    15 20 25 30 35 locking device, which is hereinafter referred to as child lock. For revolving windows fitted with swingarm fittings, there is, for example, the applicant's patent SE 8902843-5, where one of the swingarm fittings has a child lock which consists of a hook-like fitting with a recess in the form of a guide groove and a nose. The nose guides a holding member, in the form of a shoulder cut, into the groove and the groove has a rest position for the rivet in the closed position of the window and a locking position for the child's child safety device. This solution also has a separate ventilation lock in the form of a fold-out arm, which in the child-locked position folds out and is clamped between the window frame and the frame, whereby the window is prevented from being involuntarily closed. With the ventilation lock extended, the window is locked for movement both outwards and inwards in relation to the frame. The Norwegian NO 320116 is further based on the Swedish patent's child lock, but differs from this in that an extra, deep groove has been introduced in the fitting in connection with the child safety position, whereby a fixed, locked position is obtained where the window is locked in both directions. In this way, both the child lock and the air lock have been obtained with one and the same detail. The applicant has also further developed the solution according to SE 8902843-5 according to the patent SE 1001178-1, which is a combined child lock and ventilation lock.
    Furthermore, there are similar solutions on the market where some form of hook or fitting with track instructions hooks into a shoulder cut or a similar holding means, and prevents the opening of the window. These hooks or grooved hooks are arranged to be rotated, lifted or pushed to the side to release the latch and thereby allow the window frame to pass the latch position.
    The problem with the known solutions is that they do not fully meet the requirements set according to the standardized test method NT CONS 018 - WINDOWS AND FRENCH DOORS, CHILD-RESISTANT DEVICES: STRENGTH AND FUNCTlON. According to this method, the object (the window, door or door) is tested both in terms of strength - according to SS 3587, and in terms of function - according to section 7 NT CONS 018, ie the function of preventing children of a certain age from opening a window, for example. There are solutions for so-called child locks that meet the strength requirements according to SS 3587, while none of the known constructions pass the function test according to NT CONS 018.
    The test is shortened to at least 30 children aged 3-5 years, selected so that there are as many girls as boys and where these are evenly distributed in ages, social, ethnic and cultural background. The test object, hereinafter referred to as the window as an example, is placed in a rig and so that the children can get acquainted with it and understand that it is permitted to use it. An example is to place it in a preschool where the test can later take place. During the test itself, each child is first told to try to open the window completely and then the child is allowed to try to open the window for 5 minutes without instructions. Then the child, if it has not been able to open, can see when the test leader opens the window and the latch, without the test leader saying how it goes 10 15 20 25 30 35. The child then has another 5 minutes to try to figure out how to open the window.
    The test is interrupted when the child can open or after the end of the second 5-minute period.
    The results are plotted in a diagram (see figure 1) and means that if the result falls below line 1 - "Limit 1" - the barrier has passed the test and if the result ends up above line 2 - "Limit 2" - the barrier has not passed the test. ports between the lines means that no conclusions can be drawn in that situation and the test continues with additional children (in addition to the first 30) until one of the lines is passed or until a maximum of 200 children have completed the test. The result is below line 1, with full protection according to the test method's premises. However, manufacturers deliver their products with these child locks as they still make it difficult for children to open the window past the lock position. The regulations, as above, state that "the risk must be limited" for openable windows and glass sections whose frame edge is lower than 1.8 meters above the floor.For balcony doors and openable windows where the distance between the glass surface and the floor is less than 0.60 meters There must be safety fittings and locking devices that “prevent” children from opening or passing the door or window. In these cases, it is common to provide the fitting with a lock in the form of a keyed handle or the like. The main problem is thus that the child restraints on the market do not provide adequate child safety protection.
    Disclosure of the Invention With the present invention, the object is achieved in solving the problem that today's child locks do not prevent children from lifting the locking function of reversible windows, doors and shutters. The object set out is achieved from the first aspect of the invention by a method in which at least a part of the locking device, i.e. the locking means or holding means, is operated in at least two successive steps or steps, where the first step gives access to perform the second step. The purpose of this is to make it more difficult, especially for younger children, to understand how the disengagement of the barrier works. Due to the preferred embodiment of the method, an additional step is thus added for the disconnection compared to older solutions. This is crucial for advancing child safety for latches at reversible windows, doors and doors, from previously only limiting the risk of children being able to lift the child lock and open the window, door or door, with the risk of falling out, to prevent children from lifting the lock. In the past, a certain number of children always managed to lift the barrier, while the now presented procedure, according to the tests above, prevents all children of the mentioned ages from lifting the barrier, according to the test method.
    According to a preferred embodiment of the invented method, the locking means is operated in two steps. The locking member is the fitting part which is a hook-like fitting plate arranged with a recess for the holding member. The locking means and the holding means are in the locking position in engagement with each other, the window frame being locked for opening past the locking position. According to the embodiment, the locking member is slidably attached to the frame plate and the disengagement of the locking device of the locking device takes place by displacing the locking member in one direction in a first step, which allows the second step, at which step the locking member is displaced in another direction. For example, first press the locking member in the direction of the frame plate and then lift the locking member to completely release the lock. Another example is to first lift and then slide the locking member outwards, in the direction away from the user, or inwards in the direction towards the user. Other combinations are of course possible according to the preferred embodiment and the locking means can just as well be arranged on another part of the pivot arm fitting, for instance on one of its pivot arms or on the frame and then consequently the holding means for instance arranged on the frame plate or frame. By combining at least two steps for the disengagement of the latch, a child-resistant latch device which meets the requirements according to prescribed standards has been obtained. The construction thus prevents children from disengaging the lock, which older solutions cannot do.
    According to a further preferred embodiment of the method, the locking member is both slidably arranged on some part of the pivot arm fitting, preferably on the frame plate and also hingedly attached to the same. Thus, the locking function of the locking device is disengaged by first displacing the locking member in a direction, for example, upwards, downwards, inwards or outwards, relative to the user, or inwards towards the frame plate or outwards from the same. The first step allows to then perform the second step which is performed by rotating the locking member about the articulated attachment point. By using two different types of torques, displacement and rotation, it becomes more difficult for younger children to handle the lock and understand to perform the torques in the correct order and synchronized.
    According to a further preferred embodiment of the method, the locking member is both displaceable and articulated attached to some part of the pivot arm fitting, preferably on the frame plate, but in this case the rotation of the locking member takes place in the first step, and the displacement in the same way as above but in the second step.
    According to a preferred embodiment of the invented method, the locking device also comprises an operating member, which is linked to the locking member. The locking member is hingedly attached to any part of the swing arm fitting, preferably to the frame plate and furthermore the operating member is hingedly attached to the locking member at a first upper end of the operating member.
    The second, lower end is free, i.e. does not attach anything, and further the actuator is articulated attached to the same part of the swing arm fitting, preferably the frame plate, at a point between the first and the second end. By operating the other, free end of the operating member, the locking member is actuated, via the linking. According to the method, the actuator is displaced, in a first step, in a direction in order to move the actuator into a position where a second direction of movement is possible. In a second step it is then possible to perform a movement of the operating member in a second direction, preferably in the direction of the user, which causes the locking member to be actuated via the link with the operating member, whereby the locking member is rotated and thereby lifts the locking member hook and then leaves its engagement with the holding member. , whereby the latch is disengaged. In most known constructions of child restraints, the restraining member or equivalent is difficult to access, which means problems for people with reduced mobility or range. The task of the control body is to facilitate maneuvering / disengagement of the child lock for these persons. According to this embodiment, the operating member is operated in at least two steps to disengage the locking function of the locking device and thus maintains and even improves child safety and also facilitates handling for persons with limited mobility and range. Previously known solutions do not present solutions that both meet the strict requirements regarding child safety and also provide improved access for maneuvering.
    According to a further embodiment of the invented method, in addition to the above-mentioned operating means, the locking device also comprises a locking washer. The lock washer is mounted on some part of the swing arm fitting, preferably on the frame plate, in positional coordination with the other end of the actuator when it is in its locked position. The other end of the operating member is insertable behind the locking washer, i.e. between the locking washer and the frame plate, in that the locking washer in mounted position forms a space between the frame plate and the distribution surface of the locking washer. The locking washer has an open side where the operating member is thus insertable and at this side the locking washer comprises a locking lug, which is arranged to lock the other, free end of the operating member. This is the locking position according to the embodiment and by inserting the operating member into the space behind the locking washer, the locking member comes into engagement with the holding member. When disengaging the locking function of the locking device is to take place according to the preferred embodiment of the method, the other end of the operating member is first displaced in one step, in a direction for release from the locking lug, and then it is possible in a second step, displaced the other end of the operating member in a second direction , wherein the operating means acts on the locking means so that it is released from the holding means and the locking function ceases. In the locking position, the locking washer also covers the other end of the actuator and thus the locking lug and the engagement between the locking lug and the actuating member are hidden. As a result, the user must know or have the ability to understand how the device is disconnected, which is an advantage over older solutions where the locking mechanism is visible. The hidden latch according to the embodiment presents an additional difficulty which makes it more difficult for smaller children, in addition to the fact that they have to maneuver the operating means in two steps to release the latch. Furthermore, the lock washer can also be easily mounted afterwards, i.e. with already existing locking fittings according to the invention. This means that if, for example, the use of a room is changed to a room where children are staying, it is easy to supplement the locking device with the lock washer, whereby the security level is significantly increased, according to the tests reported above. Older solutions do not show this simple and cheap supplementary option when changing the use of the premises.
    According to a further preferred embodiment of the invented method, the second, free end of the operating member has a distance to the part of the pivot arm fitting on which the operating member is articulated arranged, preferably on the frame plate, preferably by a bend located between the other end and the actuator attachment to the frame plate.
    This bending means that the other end of the actuator angles out from the surface of the frame plate and thus becomes somewhat resilient, i.e. the failure of the material allows a suspension. In this way the other end becomes displaceable in the direction of the frame plate and by pressing the other end against the frame plate it becomes possible to insert the other end behind the locking washer.
    When the other end is behind the lock washer, i.e. in the locked position, and the user releases the actuator, the other end springs out slightly into the space behind the lock washer. Thereby a hook arranged on the other end of the operating member comes into engagement with the locking lug and the operating member is thus prevented from the movement which disengages the locking device. To disengage the locking function of the locking device according to the method, in a first step, the other end of the operating member is pressed against the frame plate, for release from the locking lug, and then, in a second step, the other end of the operating member is displaced in a second direction along the surface of the frame / frame plate. preferably in the direction of the user, the operating means actuating the locking means, via the link, so that the locking means is released from the holding means and the locking function ceases.
    From the second aspect of the invention, the object is achieved in that a device of the initially specified type has the special features that at least a part of the locking device, i.e. the locking member or holding member, is movably arranged in at least two different steps or moments, from its rest position at the device locking position . This means that when the locking device is in its locking position, i.e. when the locking member is engaged with the holding member, the lock or alternative holding member must be displaced or rotated, or combinations of these moments, in a total of at least two steps, to lift the locking member engagement with the retaining member. The implementation of the first stage gives access to carry out the second stage.
    It is also possible according to the embodiment to first, in step 1, actuate the locking means, and then, in step 2, to operate the holding means, or vice versa, to disengage the locking function of the locking device. Because at least a part of the locking device is movably arranged in at least two different directions, the locking device manages to prevent children aged 3-5 years from disconnecting the lock, and thereby risk falling out through, for example, a window, according to the standardized test method NT CONS 018. This is the only now known construction that exhibits adequate child-resistant protection according to the test method. One could imagine an alternative solution where a latch is first released for maneuvering by means of a separate tool, but this is a worse solution, as first of all a specially arranged tool or at least one tool is needed, and that this tool must be available in the vicinity of the window if it should not be too cumbersome to lift the latch.
    According to a preferred embodiment of the device, it is the locking member itself which is slidably arranged in at least two different directions. In the first step, the locking means is displaced in the direction along the longitudinal direction of the frame, i.e. upwards or downwards, preferably along the frame plate, in order to enable the second step. Then, in a second step, the locking member is displaced in a second direction approximately perpendicular to the first direction.
    This means that the other direction is either transversely to the spreading direction of the frame, inwards or outwards in relation to the window frame, or either towards the frame or outwards from the frame.
    The important thing is that the first step is followed by a second step and that the combination of these steps makes it difficult or prevents children to disconnect the child lock.
    According to a further preferred embodiment, the locking means is first displaced in a direction transverse to the longitudinal direction of the frame, in order to enable the second step. Then in a second step, the locking member is displaced approximately perpendicular to the first direction. This means that the other direction is, for example, in the direction along the direction of extension of the frame, for example upwards or downwards along the frame plate if this is mounted on the side frame, or either towards the frame or outwards from it.
    According to a preferred embodiment, the locking means is first displaced in a direction towards the frame, in order to enable the second step. Then, in a second step, in a direction approximately perpendicular to the first direction. Thereby, the second direction, in which the locking member is displaced, constitutes a movement along the plane of the frame / frame plate.
    According to a preferred embodiment, the locking means is first displaced in a direction out of the frame, in order to enable the second step. Then, in a second step, in a direction approximately perpendicular to the first direction. Thereby, the second direction, in which the locking member is displaced, constitutes a movement along the plane of the frame / frame plate.
    According to a preferred embodiment, the locking member is permanently attached to the frame plate, which means that the locking member can be rotated around the joint. Furthermore, the locking means is slidably arranged along the leaded attachment. This means that the two steps to be performed for disengaging the locking function of the locking device, according to the object of the invention, become selectable as to the order in which they are to be performed. For example, in a first step, the locking member is rotated to a position where the second step becomes possible, and then perform the second step - the locking member is displaced in the direction along the axis of rotation. Of course, reverse order is also fully possible, depending on how the application is selected.
    All the above-described and preferred embodiments have the main advantage over older solutions, as mentioned above, namely that they can withstand the standardized test method NT CONS 018, and thus prevent children from disconnecting the locking function of the locking device.
    An alternative to the locking means or holding means, or the combination thereof, being actuated directly, for disengaging the locking function, is to provide the locking means with an operating means. In older solutions, which only include some type of locking means and holding means, the location of these is often inaccessible. This in itself is often an explanation for the fact that the child lock is not completely secure, ie that a certain number of children are able to lift the lock, and then the function or result becomes somewhat more secure if the lock is made more difficult to access. Older solutions present constructions where the barriers are located high and / or are difficult to access in one way or another. As a result, not only children but also people with reduced mobility, such as the disabled, wheelchair users or the elderly, find it very difficult to reach the barrier and be able to disconnect it. By providing the locking member with an operating member, preferably in the form of an operating arm, which functions as an extension of the locking member, it becomes much easier to access and access and be able to disengage the locking function of the locking device. According to the preferred embodiment, the locking member is hingedly attached to a part of the swingarm fitting, preferably the frame plate, and in the locking position the locking member engages the holding member through a hook-like design, just as in the variants described above. The locking member is disengaged from the holding member by rotating the locking member about its joint, and thus lifting the locking member off from the holding member and the locking function ceases. Furthermore, the operating member is hingedly attached to the locking member, at its first, upper end, the end which is closest to the locking member. Furthermore, the actuator comprises a second, free end, i.e. it is not fixedly arranged in any other part. Between the first and the second end, the actuator is also hingedly attached to the frame plate, according to the preferred embodiment. By operating the operating member, preferably with a movement along the frame plate, in the direction of the user, the locking member is lifted off from the holding member through the interconnection with the operating member, and the locking function ceases. In this embodiment, the actuator to be handled is in two stages, where the implementation of the first stage gives access or possibility to carry out the second stage, in which the actuator acts on the locking means via its movement and via the linking, the locking means being released from the holding means. This solution has the same purpose and results as the above-mentioned procedure and alternative solutions, and thus also solves the main problem with older solutions.
    According to a preferred embodiment of the immediately above alternative solution, the first step comprises a movement of the second, free end of the operating member in the direction towards the part of the pivot arm fitting, in which the operating member is hingedly attached, preferably the frame plate. In order for this to be possible, the operating means comprises a sprain, bending or folding, just below its articulated point of attachment to the frame plate, i.e. on the side of the point of attachment which is closest to the other, free end. Thus, the other end will be at a distance from the frame plate and also have a certain failure, due to the lever formed between the point of attachment and the other end. It then becomes possible in the first step to press the operating member against the frame plate, and it then becomes possible to carry out the second step, in which step the operating member is moved in the direction along the frame plate and affects the locking member which is then released from the holding member. In its unaffected position, i.e. before the first step is performed, the actuator is locked for the movement which releases the locking function in the second step.
    According to a further preferred embodiment, the locking device also comprises a locking washer, which is arranged to lock the movement of the operating member in the locking position, i.e. to prevent the second step from being performed before the operating member is released from the locking washer's engagement with the operating member. The lock washer is mounted on a part of the pivot arm fitting, preferably on the frame plate, at the height of the position of the other end of the operating member, the end which is operated in at least two steps, according to the embodiment. The lock washer has in its mounted position a distance to the frame plate, and this distance forms a so-called locking space, and the actuator is insertable between the lock washer and the frame plate, by moving the actuator forward from its unlocked position, towards the locking space, and at the same time pressing inwards, towards the frame plate. When the other end of the operating member enters the space between the locking washer and the frame plate, in the locking space, the locking member simultaneously engages the holding member, in that the operating member and the locking member are interconnected, and now the locking device is in its locking position. When the actuator is released, it springs out against the lock washer and a locking lug arranged on the lock washer prevents the actuator from leaving the space by a hook on the other end of the actuator engaging the locking lug. Thus, when disengaging the latch, the actuator must, in a first step, be pressed in the direction of the frame plate to be released from the locking lug and, in a second step, displaced / pulled in the direction of the user. 10 15 20 25 30 35 10 In the second step, the locking function is switched off, by the movement of the actuator. Thus, a locking function which is switched off by at least two steps has been obtained. In addition, the lock washer hides how the actuator is locked in the locked position, which further makes it more difficult for younger children to understand the function, compared with older solutions where the parts and interventions are visible.
    According to a preferred embodiment, the locking lug comprises a first side arranged at the opening of the locking washer for the operating member. This first side has a bevel, a wedge shape, with its pointed part closest to the opening. The chamfer is for easier control of the actuator into the space between the lock washer and the frame plate. Furthermore, the locking lug comprises a second opposite side, relative to the first side, and the second side of the locking lug is arranged to block the movement of the operating member in the rearward direction towards the user. When the actuator has been arranged behind the lock washer and released, the other end of the actuator springs out towards the lock washer and as a result the hook ends up on the other end of the actuator, behind the other side of the locking lug and thus the actuator is locked for actuation / disengagement of the locking device. The angle between the other side of the locking lug and the surface of the locking washer is approximately right, which means that the other side forms an obstructing wall, a stop edge, which locks the movement of the actuator parallel to the locking washer. The first step for disengaging the locking function of the locking device is thus to first press the other end of the operating member inwards, in the direction of the frame plate, for release from the locking lug. Then, in the second step, the other end of the operating member is moved along the frame plate in the direction of the user and thus the operating member acts on the locking member, via its conductive attachment to the same, whereby the locking member is released from its engagement with the holding member.
    According to a preferred embodiment, the stop edge of the locking lug has a slight bevel or inclination. According to this alternative, the stop edge of the locking lug is not completely perpendicular to the flat part of the lock washer, but slightly inclined with an angle greater than 90 degrees between the flat part and the surface of the stop edge. The reason for this embodiment is that if the actuator is behind the lock washer and is locked by the locking lug, in an open window but unlocked position, i.e. an open position beyond the locked position, and the window is then closed, the hook of the actuator is prevented from getting stuck behind the locking edge. the slight slope.
    The inclination means that when the forcing force arises on the actuator, when the window is closed, the hook slides up from the locking lug without damaging the material in the locking lug.
    According to a preferred embodiment, the locking washer comprises a guide lug, arranged on the outside of the locking washer, i.e. opposite side of the flat surface of the locking washer, in relation to the locking space. The locking space can be said to be arranged on the inside of the locking washer, since the locking washer is mounted on, for example, the frame plate. This guide lug is arranged to come into contact with the lower pivot arm at the final phase of the window closing, and then the lower pivot arm will slide up on the guide lug and thus this part of the lock washer presses against the other end of the actuator in the direction of against the frame plate. This occurs the first step, i.e. the other end of the actuator and its hook is lifted from the stop lug, and when completely closed the hook can thus pass up past the stop edge and then the second step can take place - a movement in the direction along the lock washer and the hook can approach the tip on the wedge-shaped locking lug at the rear edge of the lock washer. The locking member and thus the operating member moves during the closing phase due to the movement of the holding member in the recess of the locking member. Conversely, the cutting functions when opening the window. No wear thus occurs on the stop edge of the Iås tray.
    According to a further preferred embodiment, the locking function of the locking device is disengaged by the actuator in the locking position, i.e. in its position behind the lock washer, being movably arranged in a first direction towards the frame plate, for releasing the hook of the operating member from the locking lug. The operating member is in the locked position clamped and locked behind the locking lug via the failure or tethering in the material, when the operating member is bent and its other end thus has a distance to the frame plate. In the first step, the other end of the operating member is then pressed, preferably towards the frame plate, whereby the engagement with the locking lug ceases. And in this way the actuator is moved into position for the second step - when the actuator is moved in a second direction, along the frame plate and towards the user, ie towards the room / room. Thereby, the locking function of the locking device is disengaged by the movement of the operating member affecting the locking member, via the interconnection, and the locking member is lifted from the holding member, whereby the locking is disengaged.
    Through the invention, a number of advantages over known solutions have been obtained: - The locking device is able to prevent children from disconnecting the lock, according to the standardized test method NT CONS 018, where other locks only complicate the disconnection.
    - The locking device is more user-friendly than older locks due to the control arm, which is particularly important for people with reduced mobility and yet the safety level is higher than previous solutions.
    - The locking device automatically goes into locking position when the window, door or door is closed.
    - The multi-stage handling, which is important for good safety, is handled by handling only one detail - the operating means, the locking means or the holding means.
    - The design is prepared for retrofitting of the lock washer, which makes it possible to supplement with the increased security level afterwards, if, for example, the use of a room changes and an increased need for security arises. The lock washer is a simple and inexpensive detail that is easy to assemble. 10 15 20 25 30 35 12 Brief description of the figures In detail represents in diametrical, partly schematic cross-sections or perspective views: - Fig. 1 shows an evaluation diagram from the test method NT CONS 018.

    The constructive design of the present invention will become apparent in the following detailed description of embodiments of the invention with reference to the accompanying drawings which show a preferred, but not limiting, embodiment of the invention. In addition, the invention further advances the state of the art in the field in various respects. This is realized in the present invention in that a device of the type described below is substantially as described in the characterizing part of claim 1.
    Detailed description of the figures Fig. 1 shows an evaluation diagram from the test method NT CONS 018 - WINDOWS AND FRENCH DOORS, CHILD RESISTANT DEVICES: STRENGTH AND FUNCTION. The test means that each child is first told to try to open the window completely and then the child is allowed to try to open the window for 5 minutes without instructions. The child then, if it has not been able to open, sees when the test leader opens the window and the latch, without the test leader saying how to proceed. The child then has another 5 minutes to try to figure out how to open the window. The test is interrupted when the child can open or after the second 5-minute period is over. The results of the tests are plotted according to the example where one one means that the child has not been able to open the window and a second means that the child has managed to open the window within the time limit. If the result for the 30 children falls below line 1 - "Limit 1" - the barrier has passed the test and if the result ends up above line 2 - "Limit 2" - the barrier has not passed the test. Results that end up between the lines mean that no conclusions can be drawn in that position and the test continues with additional children, in addition to the first 30 children, until one of the lines is crossed or until a maximum of 200 children have completed the test.10 15 20 25 30 35 13 Fig.2a shows a section through a complete frame 1 which comprises a lower part 2, an upper part 3 and two side parts 4. In the side parts an arch 5, preferably a window frame, is pivotally suspended by means of two mirror-symmetrically equal pivot arm fittings 6. The pivot arm fittings 6 each comprise an outer fitting arm 7, the lower part of which is hingedly attached to windows. 5.
    Furthermore, the pivot arm fitting 6 comprises an upper pivot arm 8 which in its upper end is hingedly attached to the upper end of the outer fitting arm 7. The lower end of the upper pivot arm 8 is also hingedly attached to a frame plate 10 fixedly mounted in the frame. The pivot arm bracket 6 further comprises a lower pivot arm 9 which is also hingedly attached to the upper end of the outer bracket arm 7, but below the upper pivot arm. 8 attachment. Furthermore, the lower pivot arm 9 is also hingedly attached to the lower end of the frame plate 10. At the hinged attachment point of the upper pivot arm 8 to the frame plate 10, a locking member 11 is hingedly attached to the frame plate 10 via a first link 13. The locking member 11 is further linked to an operating member 14, via a second link 15 arranged at the upper first end 16 of the operating member 14. The other end 17 is free and displaceable in at least two directions, preferably in the direction towards the side part 4 of the frame and in the direction along the surface of the frame plate 10, i.e. inwards and outwards viewed from the user's point of view. The operating member 14 is articulated to the frame plate 10 through a third joint 18, which is located between the first end 16 of the operating member and the second end 17. On the lower pivot arm 9 a holding member 12 is arranged, which is preferably a shoulder section or the like, and the locking member 11 is arranged to grip the holding means 12 for locking function. According to the clock, the window is in a position where the locking member 11 does not engage the holding member 12 but is opened to a greater degree of opening, i.e. an opening where the dimension between the lower part 2 of the frame and the lower part of the window frame 5 is greater than 10 cm. In this position the window is not blocked for movement but pivotally movable about its joints either inwards towards the frame 1 to locked position or further to closed position or continued movement outwards towards greater degree of opening or to inverted position - approximately 180 degrees - in position for window cleaning or the like . A locking washer 19 can also be seen in the gear, which is mounted on the frame plate 10 in position at the lower, other end 17 of the actuator. The locking washer 19 is designed in such a way that in the mounted position it has a locking space 28 (see figur 4b-e) between the locking washer 19 and the frame plate 10, 1 which locking space 28 the actuator 14 is inserted for locking the actuator free, other end 17.
    Fig. 2b shows the frame 1 with the window frame 5 in its locked position, which is a combined position for child locking and ventilation. The child locking position means that the window frame 5 is locked for outward movement in relation to the frame 1 and is a fixed position against outward movement, which is a safety requirement according to current standards. In this position the locking member 11, via a recess accommodated in the locking member, has come into engagement with the holding member 12, in that the recess comprises a guide arranged for the holding member 12. The locking washer 19, at the lower, second end 17 of the operating member 14, is arranged 14 to lock the movement of the actuator 14 in the locked position, which means that the other end 17 of the actuator must first be moved towards the frame plate 10 in order to be released from a locking lug 20 arranged on the lock washer 19 with a stop edge 30 (see figure 4b-e), before the actuator 14 can be operated, preferably in the inward direction towards the user, to disengage the locking member 11 from the holding member 12, via the latching device. After disengaging the child lock, the user is free to leave the actuator 14 in the actuating position or return the free, second end 17 behind the stop edge 30 of the lock washer 19. According to the figure, the actuator 14 is in its locked position, i.e. the other end 17 is locked by the lock washer 19. When closing the window, the actuator 14 will automatically be inserted into the lock space 28 behind the stop edge 30 of the lock washer 19, if not already there, as will be explained later in connection with Figures 4a-e. Furthermore, when closing, in addition, the holding member 12 will automatically enter the recess of the locking member 11, whereby the locking position is automatically switched on when closing. This means that when the window is next opened, the device with safe child lock is already activated in that both the locking member 11 and the operating member 14 are in the locked position and to disengage at least two steps of operation of the operating member 14 are required to disengage the locking function. to the second step.
    In Figure 2a, the locking member 11 is disengaged from the holding member 12 by means of the operating member 14 in the manner described above, and the window frame 5 has left the locking position. Details about the design of the lock washer 19 and how the locking of the operating member 14 takes place are explained in connection with Figures 4a-e.
    Fig. 3 shows the right-hand side part 4 of the frame 1 comprising the fixedly arranged frame plate 10, and in this the articulated upper and lower pivot arms 8, 9 and their articulated attachments to the outer fitting arm 7. Furthermore, a part of the window frame 5 which, like in common applications with pivot arm fittings, is linearly guided at its upper part by a sliding shoe 36 arranged in a slide rail 35. At the attachment point of the upper pivot arm against the frame plate 10 - the first joint 13 - the locking member 11 is also hinged to the frame plate 10. The hinged attachment allows a rotational movement of the locking member 11 about the joint 13, but this movement is limited by a lug 37, which projects from the surface of the frame plate 10, up through a recess 38 in the locking member. Furthermore, the operating member 14 is hingedly attached to the frame plate 10 through the third joint 18, around which the operating member 14 is rotatable.
    The operating member 14 is in turn linked to the locking member 11, via the second joint 15, between the upper, first end 16 of the operating member and the lower part of the locking member. Through the interconnection in the second joint 15 and through the articulated first and third joints 13, 18, a rotational movement is transmitted from the operating member 14 to the locking member 11, and vice versa.
    The freedom of movement is limited in total for the parts through the lug 37 and the recess 38 in the locking member 11 and thus also the movement of the operating member 14 is limited, so that its other end 17 never completely leaves the lock washer 19. Above the hinged attachment 9 above the lower pivot arm 9 the frame plate 10, and in positional coordination with the other end 17 of the operating member, the locking washer 19 is fixedly mounted to the frame plate 10. Because the locking washer has a distance between its flat part 21 and the frame plate 10, the locking space 28 (see figure 4b-e) is formed therebetween. Furthermore, the locking washer 19 has an opening to the locking space 28 through an open upper edge 26 and rear edge 27 through which the other end 17 of the operating member is inserted. It is shown that the other end 17 of the actuator is located behind the locking washer 19, in the locking space 28, the actuator 14 being locked and the adequate child safety thereby in force.
    Fig. 4a shows the complete pivot arm fitting 6 comprising the frame plate 10, outer fitting arm 7, upper and lower pivot arm 8, 9, the locking member 11, the operating member 14 and the locking washer 19. The pivot arm fittings are used in pairs and are then mirror-symmetrically equal to the preferred embodiment 11. the operating member 14 is mounted only on one of the pivot arm fittings 6. As described above, the locking member 11 is hingedly attached to the frame plate at the first joint 13, and preferably the construction also comprises a clamped spring (not visible) around the joint 13, which is connected to the locking member 11 so that this tends to snap against the holding means 12 when it enters the recess of the locking means, when closing the window, in order to better ensure that the child lock is locked.
    Because the recess in the locking member 11 is adapted to control and rotate the locking member 11 when the holding member 12 enters, and to be moved in the recess, the locking member 11 obtains the positions required for the window locking position and its completely closed position, and positions in between.
    The movement of the locking member 11, when closing the window, can be described as the locking member 11 first lifts up when the holding member 12 hits its outer edge, its nose, and then decreases slightly when the locking member 11 snaps against the holding member 12 / is guided by the groove and towards the end of the movement lifts the locking member 11 again to the nearest upright position, at the completely closed position of the window and the resting position of the locking member 11. When opened, the movement pattern is reversed. As described above, the locking member 11 is linked to the operating member 14 via the second joint 15, and further, the operating member 14 is hingedly attached to the frame plate via the third joint 18.
    Thus, through the interconnection between the operating member 14 and the locking member 11, the operating member 14 will also move in step with the movement of the locking member when closing and opening, respectively. According to fi guren, the other end 17 of the actuator is locked behind the lock washer 19 and apparently the lock washer 19 hides how the locking / disengagement of the actuator 14 goes to which further makes it difficult for children to understand how the child lock is disengaged. The lock washer 19 is preferably riveted or screwed to the frame plate and is very easy to supplement with afterwards by the frame plate 10 being prepared with a recess for the fixed arrangement of the lock washer.
    Fig. 4b-e shows the locking washer 19 in perspective, in plan from the underside and in section. The lock washer 19 is most easily described by referring to its mounted position on the frame plate 10, where the upper, lower, front, rear hereafter refers to its mounted position in relation to the frame 1 and from the user's point of view from the inside and out. The lock washer is preferably a plastic part which comprises the flat part 21, which is substantially parallel to the frame plate 10. Furthermore, the lock washer 19 comprises a front edge 22, with a front wall 23, and a lower edge 24, with a lower wall 25. These two walls 23 , 25 connects in mounted position to the frame plate 10, whereby a distance is formed between the frame plate 10 and the flat part 21 of the locking washer 19.
    The upper edge 26 and rear edge 27 of the lock washer 19 are open so that the actuator 14 can be inserted behind the lock washer 19, see Figure 4a. The space formed between the frame plate 10 and the locking washer 19 is referred to as the above-mentioned locking space 28. In order to achieve the adequate protection from a child safety point of view, the operating member 14 must be locked so that its movement parallel to the frame plate 10 is prevented and the locking member 11 prevented from being released. To prevent this possibility of movement, the actuator 14 is inserted into the locking space 28, through the upper and rear edge 26, 27 of the locking washer.
    The actuator 14 is slightly angularly changed to its extent, for example by a bending or folding (see figure 6a-b), which means that the actuator 14 can be pressed against the frame plate 10. Thanks to the angle change or bending, the other end 17 of the actuator is at a distance from the frame plate 10. in the unloaded state and it becomes possible to press the other end 17 of the operating member against the frame plate 10 due to the suspension in the material. At the rear edge 27 of the lock washer at the entrance to the lock space 28, the wedge-shaped locking lug 20 is arranged, with its tip 29 closest to the opening at the rear edge 27 of the lock washer. The bevel is for easier control of the actuator 14 to the lock space 28 and to the opposite edge of the locking lug. , which is arranged to prevent the movement of the actuator 14 out of the locking space 28. Thanks to the suspension in the material of the actuator 14, the other end 17 springs out in the direction of the frame plate 10, when the pressing force ceases, and thus a hook arranged on the other end 17 of the actuator 31 (see figure 5a-b), behind the stop edge 30. Thus, the actuator 14 is prevented from leaving the locking space 28. When releasing the lock of the actuator 14, the other end 17 of the actuator must first be pressed in towards the frame plate 10, the hook 31 going free from the stop edge And thus it is possible to extend the other end 17 of the operating member in the direction of the user, which via the interconnection with the The locking member 11 causes the locking member 11 to leave its engagement with the holding member 12 and the child lock to be disengaged. When the child lock is disengaged, the actuator 14 is normally in an unlocked position, i.e. not locked behind the stop edge 30 of the locking lug, but instead resting just inside the rear edge 27 of the lock washer 27, 10 15 20 25 30 35 17 at the tip of the locking lug 29. The actuator 14 can never leave the lock washer 19 completely due to the restriction of movement via the locking lug 37 and recess 38 of the locking device. However, when disengaging the child lock, the user may return the other end 17 of the actuator to its locked position behind the stop edge 30 of the lock washer. perpendicular to the flat portion 21 of the lock washer, without a slight inclination with an angle greater than 90 degrees between the flat portion 21 and the surface of the stop edge 30. So if the actuator 14 is located behind the lock washer 19 and is locked by the stop edge 30 of the locking lug, at open window but unlocked position, i.e. an open position beyond locked position, and the window is then closed, the hook 31 of the actuator is prevented from getting stuck behind the stop edge 30 of the locking lug. through the slight slope. The inclination means that when the forcing force arises on the operating member via the movement of the locking member, when the window is closed, the hook 31 slides up from the locking lug 20 without damaging the material in the locking lug 20. When the window begins to close from a position beyond the locked position, the holding member 12 automatically enters the recess of the locking member 11 when the parts come into contact with each other, by the locking member 11 then lifting slightly, as described above, and allowing an entry of the holding member 12 into the locking member. 11 urtag. Then, in the event of continued closing, as described above, the locking member 11 will lower slightly when, in the locked position, it snaps against the holding member 12, and is then successively lifted again to its rest position when the window is completely closed.
    Because the operating means 14 and the locking means 11 are linked via the second joint 15, the operating means 14 also moves. Should it then be the case that the user inserts the operating means 14 into a locked position behind the locking washer 19, after opening beyond the locking position, the inclination on the stop edge surface 30 allows , when the window is closed, and the movement of the locking member 11 between the locking position and the rest position forces the operating member 14 to move, that the hook 31 and the other end 17 of the operating member are lifted in the direction of the frame plate 10 and then leave the locked position. The lock washer is thus not damaged by breaking or the like due to the hook 31 possibly sticking to the stop edge 30. However, the inclination of the stop edge 30 is completely sufficient to block the movement of the operating member 14 at the child locked position, i.e. the partially open position when the locking member 11 is engagement with the holding means 12. Due to the bevel there is no damage to the material at the stop edge 30 of the locking lug, which would be the case if the bevel did not exist.
    An additional feature to avoid wear on the lock washer 19 is a guide lug 32 arranged on the outside of the flat part 21 of the lock washer 19. When the window is closed, as described above, both locking means 11 and operating means 14 will move depending on the position of the holding means 12 in the locking means 11 recess, and the other end 17 of the actuator will during this movement first leave the stop edge 30 through the bevel, then lock again behind the stop edge, to finally leave the stop edge 30, during the last phase when the locking means 10 15 20 25 30 35 18 11 goes into rest position in the nearest upright position. At the same time as the final phase of the closing movement occurs, the lower pivot arm 9 approaches the lock washer 19, and will slide up on the guide lug 32, which then automatically presses the other end 17 of the actuator against the frame plate 10. In this way the control of the actuator 14 is facilitated in its movement during closing and opening, respectively, and the lock washer does not wear.
    To facilitate the mounting of the lock washer 19 in the frame plate 10, a projecting mounting lug 33 is provided in the lower wall 25 of the lock washer, which is dimensionally coordinated with a corresponding recess in the frame plate 10. The mounting lug 33 also comprises a continuous recess 34 for firmly anchoring the lock washer 19 to the frame plate 10. for example with a pop rivet or screw.
    Fig. 5a-b shows the locking device in cross section in two different positions, the locking position and the started closing of the window. According to Figure 5a, the window frame 5 is in its locked position where the locking member 11 engages the holding member 12. In this position the operating member 14 must first be pressed against the frame plate 10 to release the hook 31 from the locking lug 20. This is the first step for disengaging the child lock. Then it is possible to carry out the second step, namely to move the operating means 14 in the direction of the user, the locking means 11 being lifted by the holding means 12 via the link at the second joint 15. In Fig. 5b the window is about to be completely closed and thus the operating means 14 automatically inserted into the locking space 28, behind the stop edge 30 of the locking washer, at the same time as the holding means 12 during the closing movement is automatically inserted into the recess in the locking means 11. The automation in the above steps is made possible by the locking means 11 which controls the holding means 12 into the recess. which guides the actuator 14 into the locking space 28, among other things through the guide lug 32 and the wedge shape of the locking lug 20.
    Figs. 6a-6b show the sprain or angular change / bending of the actuator 14 in relation to the frame plate 10. The sprain is arranged between the articulated attachment of the actuator 14 to the cam plate 10 and the other end 17 of the actuator. In this simple way a suspension is obtained in the material , that is, the first step of disengaging the child lock. In Figure 6a, the other end 17 of the operating member is pressed in the direction of the frame plate, whereby the hook 31 on the operating member 14 can pass the locking lug 20 of the locking washer 19 for engaging or disengaging the first step. In Fig. 6b, the operating member 14 is unloaded and thus its other end 17 and the hook 31 have tethered out and are behind the locking lug 20, whereby the movement along the cam plate 10 is prevented and thus the child lock is not disengageable. 10 15 20 1 = frame 2 = lower part of the frame 3 = upper part of the frame 4 = side part of the frame 5 = arch 6 = swing arm bes | ag 7 = outer fitting arm 8 = upper swing arm 9 = lower swing arm 10 = frame | atta 11 = locking means 12 = height | | body 13 = first link 14 = actuator 15 = second link 16 = first end of control 17 = second end of control 18 = third link 19 = | ridge tray 20 = | ridge | ack 19 BOMB 21 = | flat part of ridge tray 22 = | front of ridge tray edge 23 = the front wall of the lock washer 24 = | the lower edge of the ridge tray 25 = | the lower edge of the ridge washer 26 = | the upper edge of the ridge tray 27 = | the rear edge of the ridge tray 28 = | ace space 29 = | the thigh | 32 = strength | ack 33 = mounting bracket | ack 34 = recess 35 = slide rail 36 = guide shoe 37 = recess 38 = recess
