    The present invention relates to a child lock for mounting between a window frame and a top or side hung window frame, arranged for locking the window frame in a ventilation position, comprising a locking arm rotatably mounted on the window frame and a locking part mounted on the window frame, where the locking frame includes grooves arranged for detachable engagement with a locking pin of the locking part.
    As a general rule, windows must have a child lock unless the design makes it impossible for children to climb out or fall out through them. Technical regulations require that windows in homes that are mounted higher than on the first floor must have a child lock that does not prevent the use of the window as an escape route if required. The child lock must therefore be easy to open by adults, while small children must not be able to unlock the child lock. Furthermore, the child lock should provide a ventilation opening that is not larger than it prevents children from crawling through. The child lock should also be activated automatically when the frame is opened.
    For prior art, see GB1500194 A (Victor Sandberg), GB2414513 A (DYNATEC ENG LTD), GB2384270 B2 (ASSA AB LOG FINANCIAL SERVICES ET AL), US4259811 (Interlock Ind Ltd) and GB2217775 A (Mothercare UK LTD). All publications concern windows with devices for restricting the degree of window opening. Particular reference is made to the first two publications which show pivoting arms with grooves.
    Reference is also made to US 2012/0036781 A1 (RUNK, David et al.), GB 2391901 B (J.BANKS & CO. LTD.), GB 2263934 A (J. BANKS & CO. LTD.), GB 2409879 B ( NICO MANUFACTURING LIMITED), and GB 2353560 A (LATHAM LTD.).
    The advantage of the child lock in the present invention is that it will always lock. It is also very strong and can withstand a lot. It is also locked in such a way that you have to use two hands, and is therefore safer than today's alternatives to child locks. Another advantage is that it is advantageous in terms of production. The object of the present invention is thus to provide an improved and simplified child lock for a side-hung or top-hung window.
    The above object is achieved by means of a child lock for mounting between a window frame and a top or side hung window frame, arranged for locking the window frame in a ventilation position, comprising a locking arm rotatably mounted on the window frame and a locking part mounted on the window frame, where the locking arm for releasable engagement with a locking pin of the locking part, characterized in that the locking arm comprises a separate locking groove separated from the open groove of the locking arm, and that the locking part comprises a spring-loaded locking bracket arranged for releasable engagement with the locking groove of the locking arm.
    Alternative embodiments are set out in the respective independent claims.
    The locking groove can be arranged in a front edge of the open groove of the locking arm.
    The locking groove and the open groove are preferably angled relative to each other.
    The locking arm may also comprise a second open groove arranged for releasable engagement with the locking pin of the locking part, and the locking arm may comprise a second locking groove arranged for receiving the spring-loaded locking bar, the second locking groove and the second open groove being angled relative to each other.
    The locking bar can project through a first slot in the locking part, and the locking bar is preferably connected to an unlocking lever, which can project through a second slot and be arranged to influence the movement of the locking bar in the slot.
    The locking bar and the unlocking lever can be made of a common spring arranged in the locking part.
    The locking pin can, at least in its upper part, be sponge-shaped.
    The locking arm is preferably spring-loaded mounted on the window frame.
    A first part of the spring may be attached to one end of the locking part, and extend horizontally to a underside of the first slot, whereupon it deflects vertically upwards to form the locking bar on the top of the locking part, and then continues down through the first slot again. ; a second part of the spring may extend horizontally towards and through the slot of the unlocking lever, whereupon it may deflect back through the second slot; and a third part of the spring can run from the second slot and into the locking part, where the third part can be freely arranged inside the locking part.
    The invention is now described in more detail with the aid of the attached figures, where: Figure 1 shows a child lock in accordance with the invention mounted between a window frame and a window frame to a window. Figure 2 shows an enlarged sectional view of the child lock shown in Figure 1, seen from the inside of the window. Figure 3 shows an enlarged sectional view of the child lock shown in Figure 1, seen from the outside of the window. Figure 4 shows a locking arm with fastening device included in the child lock in accordance with the invention. Figure 5 shows a locking part included in the child lock in accordance with the invention, seen from below. Figure 6 shows the locking part of the child lock in accordance with the invention, seen from the side. Figure 7 shows the locking part of the child lock in accordance with the invention, seen in perspective. Figure 8 shows a sectional view in enlargement of the child lock locking arm and locking pin, in accordance with the invention. Figure 9 shows the parts included in the child lock in accordance with the invention, before mounting in the window frame and window frame.
    By window frame is meant the frame which encloses the window glass, and by window frame is meant the frame which is mounted in the fixed structure, such as wall or ceiling, and which encloses the window frame.
    Figure 1 shows a window frame 12 with a window glass 14 mounted in a window frame 10.1. The illustrated embodiment is the frame 12 mounted side-mounted in the frame 10. However, the invention can also be used for top-hung windows. Or for that matter also for doors and the like that are equivalent to threaded mounted in a frame.
    The child lock 20 according to the invention is illustrated at the bottom of the figure, in the area marked D, and mounted between and to the respective window frame 10 and the window frame 12.
    Figure 2 shows an enlargement of the area marked D in Figure 1, and as can be seen, the child lock 20 comprises a locking arm 22, mounted on the window frame 12, and which is arranged for detachable engagement with a locking part 24 mounted on the window frame 10. The locking arm 22 is attached to the underside of the window frame 12 with, for example, a frame plate or fastening device 26 (as shown in Figures 3 and 4), where the locking arm 22 is preferably attached to the frame plate with a rivet 27, screw or the like, and which may also be designed as or equipped with a spring 28. This spring holds the locking arm 22 in a cooking position where it can lock with the locking part 24 when opening the window frame 12.
    The child lock 20 end piece, ie. the locking part 24, is preferably made of plastic or of steel and plastic or only of steel, with its associated components. If the locking part 24 is made of plastic or steel and plastic, there should be drainage holes (not illustrated) in the front edge of the locking part. A front edge 52 of the locking part 24 can be inclined so that the locking arm 22, if it slopes slightly lower, can be guided in locking position with the locking part 24.
    Figures 5-7 show the locking part 24 of the child lock 20 in more detail. As can be seen, the locking part 24 can be designed as a platformed end piece, with a sloping front edge 52 for guiding the insertion of the locking arm 22. The locking part 24, and also the locking arm 22, can be divided horizontally into two parts, so that it different connections can be made, as the frame profiles of different window suppliers may differ.
    The locking part 24 comprises a reasonably centrally located and raised locking pin 50, preferably sponge-shaped, with which the locking arm 22 can engage. The locking pin 50 (sponge) with which the locking arm 22 engages may be, for example, a rivet which is riveted to metal, or a screw which is shaped like a sponge (as the example is shown in Figure 7) and which is screwed in place in the middle of the locking part 24, and down into the wood on the window frame 10. It can also be designed as a sleeve on the screw and which is screwed through and down into the wood. It is of course possible to only attach the locking pin 50 to the locking part 24 without it passing through the locking part 24 and down into the lower frame 10. This is most reasonable if the locking part 24 is made of steel, but is also conceivable if the locking part is made of plastic. The type of plastic is crucial in such cases. The locking part 24 preferably also comprises a pair of screws 60,62 for fastening in the window frame 10.
    The locking member 24 further includes a spring-loaded locking bar 44 or pin projecting from the locking member 24 through a slot 46 in an area leading to the locking pin 50. The locking bar 44 is connected to an unlocking mechanism or unlocking lever 42 projecting through a slot 48 on the side of the locking member. 24.
    The unlocking mechanism can be designed in several ways, but in the illustrated exemplary embodiment the unlocking lever 42 and the locking bar 44 are made of a common spring 40 which is clamped inside the locking part 24. Figure 5 shows this in more detail. The locking part 24 may on the underside comprise an opening 54 for insertion of the spring 40 which constitutes the unlocking lever 42 and the locking bar 44. A first part 40a of the spring 40 may be fixed or held in place in an opening 56 or the like in the locking part 24. The spring 40 extends then horizontally away to the underside of the slot 46, where it deflects vertically upward to form the locking bar 44 on the top of the locking member 24, and then continues down through the slot again. A second portion 40b extends horizontally toward and through the slot 48 of the unlocking lever, where it deflects back in through the slot 48. A third portion 40c of the spring extends from the slot 48 and into the locking portion 24 again, where the third portion 40c is freely disposed in a groove 58, edge or the like inside the locking member. When moving the unlocking lever 42 in the slot 48, the locking bar 44 moves correspondingly in its slot 44. The unlocking lever 42 can be equipped with a plastic knob or the like (not shown) to facilitate use.
    Function and interaction between the locking arm 22 and the locking part 24 is now explained in more detail. As shown in more detail in Figure 8, the locking arm 22 comprises an open groove 30 extending at an angle into the locking arm. When the window is closed or when opening of the window frame 12 has just begun, a waist portion 36 of the locking arm 22, due to the spring load of the locking arm, will rest or be pressed against the locking pin 50. Further opening causes the locking pin 50 to slide away from the waist portion 36 and into the groove 30. , preferably to the lowest point of the track 30. At the same time, the locking bar 44 will slide or be moved against an edge 34 in the leading edge of the groove 30, and due to its spring load in the slot 46, be inserted into an open locking groove 32. The window frame 12 is thus locked in a ventilation position, as the locking pin 50 cannot slide out of the groove 30 due to the engagement of the locking bar 44 in the locking groove 32. The groove 30 into which the locking pin 50 is inserted, and the locking groove 32 into which the locking bar 44 is inserted, are angled relative to each other, which means that the locking arm 22 cannot get out of its locking engaging the locking member 24 without unlocking it by means of the unlocking mechanism. As can be seen from the figures, the locking arm 22 thus comprises a separate locking groove 32, separated from the open groove 30 of the locking arm. rear edge 34 of the open groove 30 of the locking arm 22.
    To release the locking arm 22 from the locking part 24, the unlocking lever 42 is retracted in the slot 48, so that the locking bar 44 is displaced in the slot 46 and exits its locking engagement with the locking groove 32. The window can thus be closed. Alternatively, the locking arm 22 can be slid away from the locking pin 50 so that the window can be opened completely.
    The nose portion 38 of the locking arm 22 may also comprise a second open groove 30 'into which the locking pin 50 can correspondingly slide into locking engagement with the locking part 24.1. above. By holding back the unlocking lever 42 so that the locking pin 50 slides into the second groove 30 ', and then releasing the unlocking lever 42, the window frame 12 can be set in a second ventilation position. Release of the locking arm 22 from the locking part 24 is performed in the same manner as described above, by pulling the unlocking lever 42 back into the slot 48, so that the locking bar 44 exits its locking engagement with the locking groove 32 'and the window can be closed. Alternatively, the locking arm 22 can be slid away from the locking pin 50 so that the window can be opened completely.
    When using top-hung windows, the locking arm 22 does not necessarily have to be resiliently arranged, since the locking arm, due to the mounting and under the influence of gravity, is actuated so that the locking pin of the locking part slides into the groove of the locking arm.
