    First the steel balls to non-preventing positions, after which the control piston is pulled off by turning a locking cylinder.
    Another example of a reading device is shown in the patent document US 5,484,18O in which the locking device is intended to be arranged on the inside of a door frame. In this example, the locking device is an end plate comprising a cavity for receiving a projecting locking piston for locking the door.
    The locking device further comprises a cam arranged, in a non-rotating state, to hold the extended piston in the cavity, and to, in a rotating state, allow the locking piston to pass past the rotating cam and out of the cavity. The comb is held in its non-rotating state by means of a hook. U.S. Patent No. 4,056,277 discloses a similar device in which the cam is held in its non-rotating condition by the use of a metal ball. When opening the locking device, the hook or metal ball is first retracted, after which the frame is rotated by the locking piston pressing against and rotating the cam.
    SUMMARY OF THE INVENTION An object of the present invention is to provide a locking device which provides high security and functionality with a compact and reliable design.
    According to a first aspect of the invention, this object is achieved with the locking device according to the independent claim 1.
    The indicated locking device comprises a blocking means for locking the movement of a locking element, and a latch arranged to engage, in a first state, the blocking means in its first, blocking position to keep the blocking means immobile, and in a second state to allow a movement of the blocking means to its non-blocking state.
    The locking device is further provided with a control means arranged to control both the condition of the lock which is used to keep the blocking means immobile and to control the actual movement of the blocking means. Thus, the locking device can be designed more compact since both the blocking means and the latch of the blocking means can be moved and / or controlled with the same control means.
    The latch is preferably arranged to keep the blocking means immobile by intervening with one or more parts or structural features of the blocking means. When the latch engages and keeps the blocking means immobile, the blocking means is prevented from being pushed backwards from a position in which the blocking means helps to restrict access. Thus, a more secure locking device is achieved because the locking element is blocked by the blocking means, which in turn is kept immobile by the latch, in order to limit tampering. Thus, the locking element cannot be manipulated by an intruder without first manipulating both the blocking means and the lock, which increases the security of the locking device. Preferably, the latch itself is arranged to avoid transmitting any movement to the blocking means, whereby the function of the latch can be more easily guaranteed. In order to surface the blocking means, the lock must thus be in its second, non-holding state. By controlling the condition of the latch with the same means as for moving the blocking means, there is less difficulty in coordinating the mechanism of the locking device, which leads to a more reliable locking device. The design according to the invention also requires a smaller number of movable members, whereby there may be less wear and a lower probability of failure.
    Based on the reduced number of members, the mechanism can also be designed more compactly so that the need for space for the device is reduced.
    Preferably, the control means is arranged to control the condition of the locking and blocking means based on its position. Preferably, the control means is arranged to control the condition of the locking and blocking means on a purely mechanical basis. Preferably, the control means is movable and arranged to control the changes in state of the lock and the position of the blocking means by its movement or position, so that the positions of the locking and blocking means change with the movement or position of the control means. Preferably, the control means is also arranged to surface and / or transmit a movement to the lock and to the blocking means. Preferably, the blocking means and / or the latch are shaped so that an extreme force acting on the blocking means to press the blocking means against its non-blocking state is transmitted to and presses the latch further towards its first state. Thus, the latch will be more difficult to surface out of its holding state by someone pressing or manipulating the blocking means. This can be accomplished by designing the latch and blocking means so that the latch is pressed against the blocking means to create frictional forces that hold the latch even tighter in its initial state.
    Preferably, the control means itself comprises only a single means, arranged to transmit movement to the blocking means and to change the state of the locking lock.
    However, the control means may in turn be connected to a lock by additional links, means or elements within the locking mechanism, for generating or transmitting movement to the control means. In another embodiment, the control means may instead comprise an electric drive for moving the lock and the blocking means. Preferably, the control means is an integral part of the locking device. Thus, a key or the like is not intended to be included in the definition of a controller. In one embodiment, the locking element can also be replaced by the same control means as for moving the blocking means and the latch.
    However, the locking mechanism may also include other links or means, other than the guide means, to achieve the displacement of the locking element.
    A locking device may comprise any number of movable and stationary links and means needed to restrict or allow access to an area or space. The locking device may be arranged to cooperate with one or fl your additional locking devices of a similar, mutually equivalent, or of another type, and one or fl your closing elements arranged to close an opening, such as a door, door, gate, etc. The closing element is usually locked by to prevent the closing element from moving in a position in which it covers the opening by using one or more of the locking devices. A blocking means can be any means arranged to be kept at least partially immobile in its blocking position, preferably by the lock, and possibly also to a certain part of the control means. The blocking means is preferably arranged to directly block the movement of the locking element, but may also be arranged to block the locking element indirectly by being arranged to block a chain of means and / or elements in order to surface the locking element.
    Preferably, the blocking means is arranged to indirectly or directly block the locking element by occupying a space into which the locking element needs to be moved to be opened or unlocked. The blocking means is preferably also superficially to a second position in which the blocking element is arranged to allow a movement of the locking element and to allow said access to the area or space.
    According to one embodiment, the lock is arranged to pour the blocking means immobile by forming a fixed mechanical connection between the blocking means and a fixed blocking engaging means in the first state of the blocking. The fixed engaging means is preferably stationary relative to a housing of the locking device. In one embodiment, the fixed engaging member is a wall portion of the locking device. In one embodiment, the fixed engaging member is fixedly fixed in the housing of the locking device.
    The latch may comprise a hook design device, wherein a hook or other form of grip element or structure engages or engages a corresponding coupling part, such as a pin or a jack, to keep the blocking member immobile. Preferably, however, the latch comprises a solid body arranged to extend over a distance between the blocking means and a fixed engaging means, and to be at least partially housed in and held by both the fixed Thus, the blocking means is anchored in the fixed engaging means. Preferably, the engaging means and in the blocking means. the fixed engaging means and the blocking means closely abutting, and more preferably abutting each other, the distance being small or close to zero. Preferably, the barrier comprises only one organ or body.
    Preferably, the body is movable between a first state, in which the body is simultaneously housed within the first locking cavity in the blocking means and within a second locking cavity in the fixed engaging means for keeping the blocking means immobile, and a second state in which the locking has for fl expelled from at least one of the cavities to disconnect the blocking means and the fixed engaging means from each other.
    Preferably, at least a major portion of the latch is then housed in only one of the latch cavities.
    According to one embodiment, the control means is arranged to move along a path of movement, the guide means being adapted to substantially move the blocking means while moving along a first part of the path and to mainly control the state of the barrier while moving along a second part of the path of movement. The locking mechanism, and in particular the control means, are preferably designed so that at least a main part of the first and the second part, respectively, are separated. Preferably, the first and second parts of the trajectory are completely separate. However, the locking mechanism, and in particular the guide means, may be designed so that the first and the second part of the path of movement partially coincide. Since the latch needs to be moved to the second condition before a movement of the blocking means is allowed, it is advantageous for the control means to at least to some extent guide the latch and the blocking means along separate parts of its path of movement. In another embodiment, the speed of movement of the latch and the blocking means, respectively, may differ in size between a first and a second part of the path of movement of the control means. Alternatively, the barrier may be formed with a clearance between the barrier and the blocking means so that the movement of the blocking means may begin before the barrier has reached its second state.
    Preferably, the control means is arranged to control the state of the latch towards one end of the path of movement. Preferably, the control means is arranged to control the state of the lock against the end of the path of movement against which it is moved when it moves the blocking means towards its blocking position. Thus, the latch will slide into place after the blocking means reaches its blocking position and it will also be fl removed before fl moving the blocking means. Preferably, the guide means is also arranged to surface the blocking means towards the opposite end of the path of movement. According to one embodiment, the control means comprises an angled surface adapted to exert a force acting on the barrier in a direction towards its first state and to move the barrier in a direction other than the direction of movement of the control means and / or from the direction of movement of the blocking means. Preferably, the angled surface exerts a force on the guide means which acts to move the barrier in a direction which is at an angle between 30 - 150 ° from the direction of movement of the guide and / or the direction of movement of the blocking means, more preferably at an angle between 45 - 135 °, and most preferably between 60 - 120 °. Preferably, the surface is adapted to exert a force to move the barrier in a direction perpendicular to the direction of movement of the guide member. Thus, the guide means will move the latch in a direction away from the path of movement of the guide means, so that the latch will not impede the movement of the guide means. Preferably, the latch is arranged to rest against and to be held in position by the angled surface in its first state. Preferably, the latch is further arranged to be moved back towards its second state when the control means is retracted. Thus, it is not necessary for the control means to actuate the latch with a force when it releases the latch. Preferably, the latch is then adapted to slide back along and on the angled surface as it returns to its second state. Due to the fact that the surface is angled, the frictional force acting on the latch will be low, so that a movement is allowed without the latch getting stuck.
    According to one embodiment, the latch comprises a body having a surface which is angled relative to the direction of movement of the latch and which angled surface of the body is arranged to rest against the angled surface of the guide member. By arranging an angled surface on the body of the barrier, the movement of the barrier is facilitated.
    Preferably, the barrier also comprises an angled surface arranged to make contact with a surface in the barrier cavity. Thus, the latch can be more easily inserted into and pulled out of the latch cavity. Preferably, the body is shaped like a sphere, further simplifying the movement of the body.
    According to one embodiment, the blocking means comprises a blocking surface arranged to block the locking element from being moved in order to restrict access to an area or space. Preferably, neither the blocking means nor the latch itself are arranged to transmit any movement to or against the locking element, whether directly or indirectly. The blocking surface is preferably angled in relation to the direction of movement of the blocking member.
    Thus, the frictional force decreases when moving the blocking member into or out of its blocking position. Preferably, the blocking surface is also angled relative to the direction of movement of the locking element. Preferably, the angled surface is angled so that it faces in a direction away from the direction of movement of the blocking means when retracting the blocking means. Thus, when the locking element is pressed against the blocking means by external forces, it is easier to retract the blocking means due to the angled surfaces and correspondingly reduced frictional forces.
    According to one embodiment, the locking device comprises a combination of angled surfaces arranged on the blocking means for blocking a locking element, an angled surface arranged on the latch for abutment against the guide means, and an angled surface arranged on the guide means for abutment against the latch. Thus, a total of at least three angled surfaces are provided in the mechanism that controls the locking element. This provides a greatly reduced friction when disengaging or unlocking a locking element that is loaded.
    According to one embodiment, the blocking means comprises a control means channel housing the blocking means. Thus, the control means can control the movement, and thus arranged at least partially of the control means inside the state, of the blocking means from inside the blocking means, which leads to a more compact locking device.
    According to one embodiment, the blocking means and / or the control means comprise a slot with a limited length, and the other of the blocking means and / or the control means comprises a sliding element arranged to slide in and along said slot. In a preferred embodiment, the blocking means comprises the slot, and the guide means comprises the sliding element. The slot and the sliding element are further arranged to allow a transmission of a movement between the control means and the blocking means, and also to control the movements of the control means and the blocking means relative to each other. When the sliding element reaches an end section of the slot, movement can be transmitted between the guide means and the blocking means by the sliding element acting on the terminating wall section of the slot. However, when the sliding element slides along the slot, no movement is transmitted, thereby allowing a movement of the guide means without any transmission of movement to the blocking means. In case the guide means is arranged inside a guide member channel inside the blocking means, the guide member channel and the slot are preferably arranged in connection with each other.
    According to an embodiment, the locking element can be a piston arranged to extend a cavity in the end plate, the blocking element extends into a door frame or one in which case it is arranged to block the movement of the piston.
    The locking device is then preferably a plug-in lock arranged inside a door leaf.
    According to another embodiment, the locking element comprises a movable cam arranged in a frame which internally covers an opening to an area or a space, which cam is arranged to hold or release a piston adapted to, in a first locking position, lock a closing element in a position in which it covers the opening, and, in a second, non-locking position, allow opening of the closing element. The cam is further arranged to be movable in an unlocked condition to allow passage of the locking element out of (and into) engagement with the cam. The blocking element is then arranged to block the movement of the cam in the first state of the blocking element in order to force the frame to engage with the locking element. Preferably, the locking device comprises an end plate comprising a rotating cam arranged in connection with a cavity for receiving the locking element, which end plate further comprises the blocking means, the latch and the control means. Preferably, the locking device is further an electrical end plate, the condition of the cam and the movement of the blocking means being electrically controlled and driven by the control means.
    According to a second aspect of the invention, the above object is also achieved with the locking device according to the independent claim 13. The reading device comprises at least one reading element, such as a piston or a cam, movable between a first, reading position, in which the reading element is arranged to be kept immobile to restrict said access, and a second position, in which the reading element is unread, and a latch arranged to, in a first state, keep the reading element immobile in its first reading position and to, in a second state, allow movement for the reading element into and out of its initial state. The reading device further comprises a movable control means arranged to control both the condition of the lock and the movement of the locking element. Thus, the reading element will be more securely held in its reading position by the latch, while the reading device may be more compactly designed and more easily controlled by the guide means.
    This reading device shares many of the advantages of the reading device described previously according to the first aspect of the invention, and in fact the present reading device may be designed to include similar features as the features of the blocking means described above. Preferably, the reading element is then shaped as a straight reading piston which moves with a linear movement.
    The control means is arranged to move both the piston and to change the current state of the latch.
    In another embodiment, however, the guide means is rotatable, and the reading element is rotatably attached to the guide means for movement between its first and second positions. Preferably, both the reading member and the guide member are rotatable and can be moved together. Preferably, the latch comprises a solid body arranged to read the guide means and the reading element from rotating relative to each other. Since the movement of both the reading element and the control means is limited in other points, the reading of the relative rotation can effectively keep both the reading element and the control means immobile from tampering.
    BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described as a number of non-limiting examples of the invention with reference to the accompanying drawings. 10 15 20 25 30 ll Figs. 1a-d show a locking device in the form of an end plate comprising a locking element in the form of a cam, and which comprises a blocking means and a lock according to an example of the invention.
    Fig. 2 shows a second example of a locking device comprising a locking element, a latch, and a control means for controlling the condition of the latch and the movement of the locking element.
    DETAILED DESCRIPTION I fi g. 1a, a reading device 1 is shown in the form of an end plate according to an example of the invention. The figures show only the parts belonging to the invention to increase readability and visibility. However, the omitted parts are well known in the art and can be found in the literature on electrical end plates.
    In this example, the locking device is an end plate adapted to be fixedly arranged inside a door frame or the like. The locking device is arranged to lock a closing element from being opened, which closing element is adapted to cover an opening into an area or a space, and may be a door, door, lid or the like. The closing element is provided with a corresponding own locking device, which in this example comprises a locking piston 3 arranged to be extended in a first, read condition, as shown in fi g. la, and to be withdrawn in a second, unlocked state.
    The locking device comprises a housing 5 which encloses the reading mechanism and forms a cavity adapted to receive the locking piston in the extended state of the piston. The locking device also comprises a cam 7 arranged in connection with the cavity and adapted to hold the locking piston inside the cavity. The cam 7 is then arranged to, in a first, locked condition, prevent the extended locking piston from moving out of the cavity in the opening direction of the closing element, and, in a second unlocked condition, to be rotatable to allow the locking piston to pass out of the cavity to allow opening of the closing element.
    Thus, either the closure member can be unlocked by retracting the locking piston and / or by rotating the cam, and correspondingly, the locking member is locked by the combination of blocking the cam from rotating and projecting the locking piston into the cavity.
    The locking device 1 further comprises a blocking means 9 arranged to, in a first blocking state, block the cam 7 from rotating.
    The blocking means 9 is then arranged to be placed in the path of movement of the cam in order to block the cam from rotating, the blocking means being arranged to occupy a space into which the cam needs to move in order to be able to rotate. The blocking means comprises a blocking surface 11, which is adapted to be in contact with a corresponding surface 41 provided on the cam to block the cam from rotating. The blocking means is further movable to a second, non-blocking position, whereby the path of movement of the cam can be left unobstructed so that the cam can rotate.
    An unauthorized individual can try to open the door by applying a large force to the cam 7, in order to force the cam to rotate and to allow the locking piston to escape out of the end plate for opening the closing element. In order to strengthen the safety of the locking device, the locking device thus comprises a lock 13 arranged to keep the blocking means 9 immobile from movement when the blocking means is in its blocking position and when the locking is in a first state. The latch 13 is further arranged to allow movement of the blocking means in a second state of the latch. Thus, if the force is applied to the cam, either by pressing on the cam or by knocking, the latch prevents the blocking means from moving.
    The locking device further comprises a control means 15 adapted to both surface the blocking means between its blocking and non-blocking positions, and to control the state of the lock 13. In this example, the control means 15 is movable and arranged to move the latch between its states by changing the position of the latch. By arranging a common control means 15 for controlling both the position of the blocking means 9 and the state of the lock 13, a combat act can further increase the reliability since there is a smaller risk that only one of the more designed locking device is provided. increases the blocking means or latch to be moved, which could be the case if they had been operated separately, or the blocking means 9 is operated to move before removal of the latch.
    The locking device comprises a locking engaging means 17, which is fixed relative to the housing of the locking device, and arranged to provide at least one surface or other feature which provides a support for and engages with the locking device.
    In this example, the engaging member 17 is rigidly attached to a wall portion of the housing 5 of the locking device. The latch is in turn arranged to engage with both the latch engaging member 17 and the locking member 9 in the first state of the latch to keep the locking member immobile. In this example, the latch 13 comprises a solid body arranged to extend over the distance, and to form a latch coupling means for securely securing the blocking means. For this purpose, mechanical connection, between the blocking means and the latch, is adapted to abut one or more surfaces of both the blocking means and the engaging means, and to transmit forces from the blocking means to the engaging means for holding the blocking means in place. In the second state of the latch, the latch is arranged to release the blocking means for movement by avoiding the formation of any mechanical connection between the blocking means and the engaging means.
    In this example, the engaging means 17 comprises a locking cavity 19 arranged to at least partially accommodate the catch within the cavity in the first state of the catch. The barrier cavity 19 is also arranged to hold the barrier 13 securely inside the cavity in the first condition by the surfaces of the cavity abutting closely against the barrier. Thus, the latch can transmit forces in a large number of directions and / or angles to the engaging member in its first state.
    The blocking means 9 similarly comprises a locking cavity 21 for at least partially accommodating and securely holding the catch 13 inside the cavity in the first state of the catch, similar to the engaging means. The latch is further solid and rigid and thus transmits forces arising from a movement of the blocking means 9 from the blocking means to the engaging means 17. In the second condition the latch is adapted to be located outside at least 21 of one of the locking cavities 19, the engaging means or 14 the blocking means, whereby the lock can not transmit any forces to the engaging means from the blocking means, and thus also allows a movement of the blocking means.
    The locking device further comprises a spring 23 arranged inside one of it 19 of the engaging member, which spring is arranged to press the latch out of the groove cavities, for example inside the latch cavity. The guide means 15 in turn comprises an inclined surface arranged to press the latch into the latch cavity against the force of the spring and against the first state of the latch. Thus, by moving the guide means, the condition of the latch can be controlled by pressing the latch into, or allowing the latch to come out of, the latch cavity. Thus, the control means controls the state of the latch in cooperation with the spring.
    In this example, the blocking means 9 comprises a channel 27 adapted to at least partially accommodate the control means 15 inside the channel. The channel is further provided with a surface 29 at one end of the channel, and the guide means is adapted to move the blocking means by pressing against the surface. The channel is further provided with side surfaces which guide the direction of movement of the control member inside the channel. In this example, the channel is surrounded by, and is almost completely enclosed in, the blocking means, but in another example, the channel could also be provided on a surface of the blocking means. The channel 27 is further provided with a channel opening 31 for allowing the control means to pass into and out of the channel. Furthermore, the space of the channel is connected to the cavity of the locking cavity 21 so that the control means 15 can control the state of the locking from inside the channel.
    In this example, the guide means 15 comprises a piston slidably arranged inside the channel. The end of the piston arranged at the far end of the channel is provided with the inclined surface 25 arranged to abut against, and to control the state of the lock.
    The blocking means 9 is further provided with a slot 33, which is arranged to run along a limited length of the channel. The guide means is provided with a sliding element 35, in this example in the form of a pin, which is arranged to run in and slide along the slot. In this example, the slider is attached to the piston cup.
    The combination of the sliding element 35 and the slot 33 thus exerts a control of the relative movement between the blocking means and the control means, and also helps to transmit movement and forces between the means. In particular, to the blocking means 9 for moving and changing the blocking means, the sliding element 35 can transmit movement from the control means position when it reaches and presses against a terminating end of the slot 33, while failing to move the blocking means while the sliding element slides along the slot. Of course, the slot could also instead be provided on the guide member, and the sliding element on the blocking member.
    The locking device further comprises a solenoid 37 arranged to provide a movement to the control means and thus to surface the blocking means and the latch. In this example, the solenoid 37 is arranged to move the piston of the guide means by the action of a magnetic or electric field generated in the solenoid.
    The operation of the solenoid is in turn controlled by a logic or electrical circuit (not shown), which is arranged to receive input signals from a user when the user turns a key, operates a remote control, or some other form of locking actuator. Thus, the movement of both the blocking means and the latch originates from the same source and is transmitted via the same control means.
    In the following, the function of the locking device is shown with reference to fi gs. lb-d. I ñg. 1b, the locking device 1 is shown in an unlocked state. The blocking means 9 is placed in a non-blocking position, in which the blocking means is thus placed next to the cam, so that the cam can rotate without obstacles. The latch 13 is housed inside the latch cavity 2 1 of the blocking member and also projects down inside the channel 27 so that it rests against the inclined surface 25 of the guide member 15.
    The recess means 17 comprises a block depressing surface 39 arranged above and level with the opening to the block cavity 21 of the blocking means, so that it ensures that the block remains inside the cavity.
    Continue from ñg lb to ñg. 1c, the control means 15 is pushed to the left in the figure so that it moves the blocking means 9 towards its first, blocking state. holding down the locking cavity of the blocking means, and thus, along a first part of the blocking depression surface 39, the lock continues inside the path of movement of the control means, the control means 15 moves the blocking means without 13 states. The force of the blocking means can be transmitted via either or both by the latch to actuate the latch from the guide means to be pressed against a wall surface of the latch cavity and / or by the sliding element pressing against an end surface of the slot.
    I fi g. 1c, the latch 13 has reached the opening to the latch cavity 19 in the engaging member 17, the latch being pressed into the latch cavity of the engaging member by the inclined surface 25 of the guide member. Thus, the condition of the latch is controlled along a second, and later, part of the path of movement of the control member 15. The latch is pressed into the latch cavity of the engaging member, as shown in fi g. ld, so that it extends over the distance, and forms a mechanical connection, between the blocking means and the engaging means for keeping the blocking means 9 immobile. At the same time, the blocking member slides in place under the cam 7 so that it occupies a space in the path of movement of the cam, whereby the cam is locked from rotating. The cam thus prevents the locking piston 3 from exiting the cavity behind the cam, so that the closing element is locked.
    When unlocking the cam 7, the guide means 15 is retracted along a first part back into the cavity of the blocking means (goes back from fi g. Ld to fi g. Lc) of the spring 23. of its path of movement, so that the latch 13 is pressed. The blocking means is then no longer kept immobile by the latch. The control means avoids transmitting any movement to the blocking means during this "second" part of the path of movement. At the same time as the latch is released, the sliding element 35 reaches the rear end of the slot, and thus begins a transmission of a movement from the guide means to the blocking means 9 to remove the blocking means from blocking the cam.
    A possible disadvantage of blocking the cam 7 with a blocking means 9 is that if the frame is loaded with a force, for example from the piston, the cam will be pressed against the blocking means which leads to an increased friction, which can prevent the blocking means from being retracted and prevent the closing element from becoming unlocked. To reduce this problem, the blocking means 9 is thus provided with an angled blocking surface 11 arranged to be in contact with the cam 7, which dramatically reduces the frictional forces experienced by the blocking means when the cam is loaded.
    However, the angulation of the blocking surface 11 may lead to the force which loads the frame simultaneously applying a force which presses the blocking means against its non-blocking state. This detrimental effect is largely negated by the inclusion of said latch 13.
    The latch 13 in this example is shaped like a ball, and is thus on a similar blocking means, and the surface of the guide means which is in contact with the latch is provided with an angled surface 43 which abuts also the angled one, which increases the number of angled surfaces to three . Thus, the frictional forces that could contribute to causing a part or parts of the locking mechanism to get stuck are reduced. In this example, all three angled surfaces 11, 25, 43 are angled so that they face in directions which are at an angle relative to the directions of movement of all three of the blocking means, the guide means and the latch, so that the frictional forces are reduced in all these cases. Although this invention has been described as a preferred embodiment in the form of an end plate, the mechanism with a common control means for both a blocking means and a latch may just as well be applied to other cases, such as a blocking means provided to block a locking element in the form of a locking piston from to move.
    I ñg. 2a-b show another example of a locking device 51 according to a second aspect of the invention. In this example, the locking device is a lock which comprises a locking element 53 in the form of a locking piston, and which is adapted to be attached to a closing element 55 arranged to cover an opening into an area or a space to restrict access to the area or space. The locking piston 53 comprises a blocking part 57 arranged to extend into a cavity or similar coupling part placed in a frame or in another closing element, in order to keep the closing element locked. According to the invention, the locking device 51 comprises a latch 59 arranged to keep the locking element 53 immobile in substantially the same manner as the latch 13 in the previous example kept the blocking member 9 immobile. The locking device 41 further comprises a control means 61 arranged to control both the movement and the position of the locking element 53 and the condition of the groove 59 in response to the operation of a locking cylinder with a key, signals from a remote control, or other forms of input from a user.
    The locking device further comprises a latch engaging member 63 provided with a latch cavity 65. In this example the latch 59 is spherical, and the latch cavity is dome-shaped. The inner surface of the catch cavity 65 is slightly angled, so that when the catch is pressed against the surface, for example when the locking element is retracted, a force is applied to the catch 59 which pushes the catch out of the catch cavity 65. Thus there is no need for a spring. Since the angle of the mandrel-shaped surface is very low adjacent the opening of the cavity 65, the compressive force is small and not sufficient to force the catch to move on the guide member in case someone applies a large pressing force to the locking element. l fi g. 2b shows the locking device in a state in which the locking element is being retracted. The guide member has been fl moved to the left in the figure and the pin makes contact with the left end of the slot, so that it transmits a movement from the guide member to the locking element. The latch has also fallen into the channel formed inside the locking element, either due to gravity, or, as here, due to the oblique surface of the latch cavity.
    In most other respects, the locking device 51 is in fi g. 2 is designed in a corresponding manner, and comprises the features of, the locking device shown in connection with figs. 1a-d, however, with exclusion of the cam and substitution of the blocking means with the locking element.
    The invention is not limited to the embodiments shown but can be varied freely within the scope of the appended claims. In particular, the shapes of the locking element, the blocking means, the locking means and the control means can be chosen arbitrarily as long as they have the ability to perform their intended function. The sizes, positions and orientations of the various elements and members can also be arbitrarily changed to suit the geometry of a specific locking device. Although the paths of movement of the members and elements are shown to be mostly linear, any, or all of them, may be designed to move along a rotating path or a curvilinear path. One or both of the blocking means and the latch can also be designed as hooks instead of solid bodies, and the control means can be driven by a mechanism rather than by an electrical device. Finally, the features shown for the device can be in fi gs. la-d are also implemented in the device in fi g. 2, and vice versa.
