Abstract

Sliding sash lock comprises at least two locking bars (18) and a gear (38, 44). The locking bars are pre-tensioned for automatic movement from their open position into their locking position. The sliding sash lock has a locking element (72) moving between a locking position and a release position. In its locking position the locking element prevents movement of the locking bar from a locking position, in which it engages in an opening in the sash connecting element, into the open position, and in its release position allows movement of the locking bar from the locking position into the open position. Preferred Features: The locking bars are pre-tensioned in their locking position by the elastic restoring force of at least one restoring spring element (64). The locking element is coupled to a key-operated lock unit (78).

Description

Sliding blade lock.

The present invention concerns a lock Sliding blade for the insertion and interlocking of a sheet sliding, preferably a sliding door, according to the preamble of claim 1.

A lock of this kind is known for example, by GB 2 168 748 A. This document shows a lock for a sliding leaf in which some latches are prestressed by springs to their locked position in such a way that a sliding blade equipped with the known lock, automatically applying the latches behind of the leaf connection element and thus keeping the sliding leaf in the connection element thereof.

In the known sliding leaf lock it has described a lever operable through a control system (see: "control 44" in Figure 3 of document GB 2 168 748 A), with which the upper of the two latches can be locked of the known lock in the interlocking position. The lever does not exert influence of any kind on the movement of the lower latch and therefore this lower latch remains unlocked

Another sliding blade lock is known for document GB 2 212 849 A. This presents a kind of insurance against wrong maneuver. Two latches are coupled by means of a coupling part to perform a joint movement. Some means present the latches towards their locked position. A blocking member presented towards its blocking position blocks the movement of the coupling part both when the latches they are in their locked position as when they are in its open position, that is, retracted inside the housing of the lock. This means that a sliding sheet provided with the lock known by GB 2 212 849 A is not embedded automatically with a leaf connection element to approach this one.

The drive means for moving the member lock and the coupling part is exclusively a pallet of closing a profiled light bulb lock. Through the movement of the closing pallet is first made the member of lock with your gear appendage exit a gear opening of the coupling part and then, as the movement continues of the closing pin, the coupling element moves from the locking or interlocking position to the other position respective.

The known insurance against mishandling causes the sliding leaf to be blocked by means of a spike coupled with a proximity probe a movement of the coupling part from the opening position to the interlocking position. The sliding leaf being closed, the proximity probe is inserted in the housing of the lock, so that the locking element is located in the area of a recess of the coupling part, whereby this part coupling can then move to the position of interlocking

Another sliding blade lock is known for US-A-5,820,170. In this known lock the coupling element and latches coupled with it are joined with two compression springs of such way that the latches, due to a neutral action exceeded caused by compression springs, they remain in each of its positions: opening position and position of insert.

As a security measure against an opening no desired of the lock, some projections of the coupling element fit, in the insertion position, in the attachment appendages of a guide groove of the coupling element and thus exclude a opening movement of the latches without simultaneous maneuvering of a nut as an input element of the gear.

In this sliding leaf lock of the state of the technique is disadvantageous the fact that the latches, after the opening of the sliding leaf lock, are in its opening position and are held there by the springs of compression. Therefore, a sliding blade provided with this lock cannot be embedded and retained in a connection element of said sheet by a simple closing push or pulse of closing.

If you should think about making this push of closing preventively bringing the latches to their position of fit while the sliding blade is open, this measurement does not provides no additional help, since the latches are insured in their locked position and therefore cannot deviate momentarily when entering the corresponding opening. A possibility of independent blocking of the nut.

It is also known by the document DE-AS 11 52 037 a door lock folding slides whose latches are prestressed by force of spring to the locked position. To open the door, the latches are pressed by spikes provided in a nut by turn of this nut from the insertion position to the position of opening. In addition, the latches are articulated so tiltable on a car that can be moved linearly from the lock of the lock or towards this one. The car is moved towards outside the lock of the lock by an eccentric formed in the nut when turning it against the prestressing of a spring. By moving the car out of the lock, the latches configured as hooks move penetrating into greater measure in the lock housing (position of interlocking), so that the folding door provided with the lock can be approximated to the leaf connecting element in the one that the latches fit.

Also, a wheel is provided in the nut toothed that is meshed with a zipper formed in a slide. Through this gear wheel the movement is transferred from turning the nut to a linear movement of the slide. The Sliding has a projection that in the interlocking position of the latches can be coupled, by turning a disk of interlocking, with two spikes arranged in it and retained like this firmly. The interlocking disk rotation is produced by the closing bolt of a light bulb lock which, when turned bulb lock along an angular range of rotation determined, it is coupled with a recess of the coupling disc and drag the latter. It is thus possible to block the lock.

In this state of the art lock is disadvantageous the fact that the two latches have to be arranged in the vicinity of the nut. This restricts the possibility of arranging the insertion points of the sliding leaf with the corresponding leaf connection element. Besides, the Lock structure is complicated due to the large number of components.

Therefore, the purpose of the present invention it consists of providing a lock of the exposed gender for a sliding blade with a simple structure and a security against increased unwanted opening compared to the state of the technique.

This problem is solved by means of a sliding leaf lock with all the features of the claim 1.

A sliding sheet can be, for example, the sheet of a sliding door or the frame of a sliding door (for example, in the case of a glass door) or a window slide. It is also imaginable to use the lock according to the invention in roller shutter doors, such as those known, for example, as garage doors, blinds Window roll-up or furniture.

The leaf connection element designates the part with which the sliding leaf lock is interlocked arranged on said sheet. Therefore, as a connection element of the leaf come into consideration, for example, a stringer of a door jamb, a window frame, a wall, the floor, etc. or, in the case of double-leaf doors or windows, one stringer of another Door or another window.

The substantially movable coupling element in a linear direction, with which the at least two are coupled latches to perform a joint movement, makes it possible to also have at least two latches with a great distance of each other on the sliding sheet. For example, a latch can be disposed in an extreme area of the leaf surface slide that faces the connecting element of said sheet and the less another latch may be arranged in the extreme zone contrary to this surface. Due to the coupling of the at least two latches with the at least one coupling element are also guarantees the joint movement of the latches along of great distances.

The locking position of the latches is a position in which the latches are embedded in the element of leaf connection, for example in a closing plate there provided, so that the sliding blade can be moved towards outside the connecting element of said sheet only by actuation of the drive element. The drive element can be here a rotating handle, such as a doorknob door or, in the case of automatically opening sheets, for example A servomotor

The at least two latches can be moved by the drive element through a gear from its locked position to its open position. The flow of force from the drive element as a point of introduction of force is effected through an input element with which the drive element can be coupled, until finally reaching the latches. In this way, the actuating element can be arranged in places of the sliding leaf favorable in the ergonomic aspect or in the safety technique irrespective of the places of arrangement of the pesti-
llos.

Also, the at least two latches are prestressed to its locked position. This makes possible a insert the latches on the leaf connection element with regardless of whether the maneuver element is maneuvered. Is it is only necessary that the sliding blade be closed by pushing it with a force or driving it with a speed that is enough for the latches, when tripping over the connecting element of said sheet, be moved in the direction of its opening position against of the prestressing force acting on them. By continuing the sliding blade movement, the at least two latches, by example after the latches have reached a part of fit the connection element of said sheet, are driven towards its insertion position under the influence of the force of prestressed and embedded in the leaf connecting element. The Insert part may be, for example, a closure plate.

In addition, the sliding blade lock comprises a locking member that can move between a position Lock and a release position. In the locked position the blocking member inhibits a movement of the latches from an interlocking position to the opening position. Thank you this inhibition of movement can be ensured in a manner simple that the latches cannot be moved from the position interlocking to the opening position due to the attack of a tool, possibly also after drilling the sheet. To overcome this blockage, a criminal would have to know the exact place where the movement inhibition is carried out by the blocking member. On the contrary, in the position release of the blocking member a movement of the latches from the interlocking position and from the position of insert, so that, when the sliding leaf is closed, you can produce an insert of the latches in the at least one opening of the connection element of said sheet.

Due to the constructive configuration of the lock according to the invention and especially due to the flow of force indicated above, the blocking member attacks directly on the coupling element. It can increase like this the security of the lock against unwanted opening, since the blocking member can be arranged in any place at length of the coupling element.

The interlocking position of the latches it can be here a position similar to the insertion position, in which, when the sliding leaf is closed, the latches attack in the connecting element of said sheet with a greater force in comparison with the insert position or fit with a covering greater in the at least one opening. This can be achieved by example, making the coupling element move true stretch in the direction of moving away from the opening position from the locking position to the interlocking position.

It should be noted at this point that the positions of the at least two latches: opening position, position of insert and interlocking position, refer in the same way to the coupling element due to the coupling between the latches and said coupling element. When you say in what it follows that the coupling element is in one of the positions, this means that the coupling element occupies a position in which the at least two latches are in the cited position.

The at least two latches can be prestressed by the force of gravity towards its position of fit in a particularly simple way in appearance constructive. This can be achieved, for example by making the latches and / or the coupling element are provided in one or more suitable sites additional masses that cause a prestressing force of the latches towards their position of insert or a torque that acts in this way. However, a prestressing induced by the force of gravity can be performed without major problems only for a limited number of motion paths of the latches. Therefore the lock Sliding sheet preferably comprises at least one element of recovery spring, by elastic recovery force of which the at least two latches are prestressed towards their insert position. Due to the forecast of a spring element Recovery of this class can guarantee a prestressing of the latches regardless of the movement path of the same.

The blocking member can be maneuvered from different ways. For example, in a door accessible from both sides it is imaginable to provide a sliding or rotating button attached with the locking member on one or both sides of the door. Without However, the blocking member is preferably coupled with a lockable drive unit with key. In this way, the Sliding blade lock can be moved from both sides of said sheet only by persons authorized to pass from its release position to the locked position, and vice versa. By Therefore, the safety of the leaf lock can be increased Sliding and space secured by this lock. They are considered as especially safe profiled light bulbs, so the lock unit preferably has a profiled bulb by means of whose closing pin the locking member can be moved from the locked or released position to the other position respective.

It is imaginable to use the lock unit, especially the profiled bulb lock, exclusively to move the locking member between its two positions. Further, The lock unit may be configured such that, apart from the blocking member, be able to also move the minus two latches from their insertion position or position of interlocking to its opening position. In this case, the sliding leaf lock according to the invention, for example by The use of a two-step lock unit could be in an unlocked process (movement of the blocking member of the lock position to release position) and open (movement of the latches from the locking position to the opening position). This possibility of maneuvering the lock of the sliding blade increases the comfort of its handling.

A possibility can materialize constructively simple and therefore cheap, but safe, for inhibit the movement of the at least two latches by means of the blocking member causing it to be in its locked position locking member engages at least partially in a recess of blocking of the at least one coupling element. The member of blocking may have a projection in the form of a cam, spike or similar that fits into a recess or groove of the element of coupling or one of the latches.

This outgoing or cooperating recess with it may be provided with guide chamfers or the groove layout can be selected in such a way that by moving the locking member towards its locked position causes a movement of the coupling element from its position of snap into its interlocking position.

To increase the security of the insured space with the sliding blade lock it can be advantageous to forecasting of the interlocking position in addition to the position of insert. However, the sliding leaf lock according to the invention and especially its at least two latches can be configured in such a way that the insert position already guarantees sufficient retention of the sliding sheet in the element of connection of said sheet. In this case, the interlocking position it can be identical to the insertion position, which simplifies the constructive structure of the sliding leaf lock and, by Therefore, it reduces your manufacturing costs.

To avoid an interlocking or unlocking involuntary sliding blade lock, it is advantageous that the blocking member has at least one superable insert that hold in at least one of its positions: lock position and release position, preferably in both positions. This superable insert can be formed, for example, by at least one countersink fitting or at least one attachment appendix, in which attacks a profiled spring element. Advantageously, a countersink is provided on the locking member or an insertion site for each of its positions. It can prevent thus the blocking member whose movement guides are worn due to frequent maneuvering and in which formed thus a slack, involuntarily reach the position of lock or to a position that locks the coupling element or the latches, or the blocking member moving out involuntarily from the locked position and free movement of the latches.

A lace of advantageously is obtained secure interlocking of the locking member in the element of coupling when the locking member can be moved by means of a substantially linear displacement movement, in transverse direction to the direction of movement of the element of coupling, between its two positions: lock position and release position. Since in principle a force cannot present an orthogonal component to your action direction, it ensure with this feature that the coupling element does not transmit this displacement force component to the member of blocking in case it is exerted on the coupling element a force for unwanted opening of the leaf lock slide. A criminal who would like to overcome the lock according to the invention is then obliged to first move the member of lock and then the latches. Therefore, you need more time to the opening of the sliding leaf, which represents a threat to your plan and can make you give up on it with a high probability.

As an additional security measure, the unit of lock, especially the profiled bulb, can be arranged on the sliding sheet such that the pallet of lock in a key removal position of the unit lock, especially the profiled bulb lock, secure the blocking member in at least one of its positions: lock position and release position, against a movement in the direction of the other respective position. It can be simplified like this the structure of the sliding leaf lock according to the invention, since, to materialize the security function, they do not have to Stay additional components in the lock housing.

To transmit a movement of the element of latch drive, gear input element it can be formed in a simple case, for example, by one of the At least two latches. The drive element is coupled then to move with the latch when installing it in the sliding leaf lock, so a movement of the element of maneuver is transmitted directly to one of the latches and to the other through the coupling element. However, you can achieve greater freedom of construction by making the gear understand the coupling element and as an element of input a nut coupled with it. A force is then transmitted from the maneuver element to the nut, from this to the element of coupling coupled with it and, finally, to the latches. How nut within the meaning of this application is generally understood a force transmission component that is attached or can join with a maneuvering element, which is set in rotational motion by the maneuvering element and that transmits this movement as linear movement or rotating movement to another component.

To be able to exclude or at least reduce a risk of injuries of people who, by pushing or driving the sliding blade to close it, they are close to it or even have your hand on the drive element, the nut can be coupled with play clearance to the coupling element of such that this coupling element can be moved from the locked position to open position without movement simultaneous nut. Through this movement slack you ensures that the drive element coupled with the nut does not make any movement, especially impact movement, when the latches move from their locked position in direction to its opening position with approach to the opening of the leaf connection element. Therefore, the sliding blade it can also be closed by pulling the drive element itself without the latter making an unexpected move by the user to fit the latches on the connecting element of said sheet. In addition, you can reduce the force required for an insert automatic latches on the leaf connection element, since, due to the slack of movement, they move less masses.

The transmission of force from the nut to the at least one coupling element can be made, for example, causing the nut to present a gear appendage that fits into a gear recess of the at least one coupling element. This shape adjustment gear produces safe operation together With high durability of the lock.

In order to guarantee a defined position of the drive element, especially after an insertion of the sliding blade lock, the nut can be coupled with A replacement device. As coupling class especially safe, the nut can present a control appendix which is coupled under form adjustment with a device replacement.

The movement slack mentioned above can materialize easily by making the recess of engage in the direction of movement of the at least one element of coupling is larger than the dimension of the appendix of gear in this direction.

A simple insertion of the latches on the leaf connecting element causing the At least two latches are configured as hooks. In this case, the hook sections of the at least two latches can be applied behind surfaces of a closing plate in the element of blade connection and thus secure the sliding blade by adjusting form in the connecting element of said sheet. The movement automatic latches from the position to the position Opening when pushing or pushing the blade to close it can be provided by providing guide chamfers in the latch and / or in the connecting element of said sheet.

In principle, the at least two latches can be linearly mobile between its insertion position or / and position of interlocking and its opening position. However, you can get the same or even greater security of the lock with a lower construction cost when the at least two latches They are swivel mounted on the lock. It's enough then articulate the two latches only at a pivot point. It is especially preferred that the latches are arranged in the lock so that they can swing in opposite directions. By tilting latches in opposite directions you can prevent or at least delay a fracture and break-in by leverage of the sliding blade, since at least one latch remains always locked in the connecting element of said sheet  when there is a movement of the sliding blade in the direction parallel to the plane of the lock of the lock.

The same sliding blade lock can be used in different kinds of sliding sheet construction when the extent to which the at least two latches protrude from the lock in its interlocking position is adjustable, preferably for each latch regardless of at least Another latch Varying the extent to which the at least two latches come out of the lock or the lock of this one, the lock can be adapted to class dependent distance of construction that exists, when the sliding leaf is closed, between the at least one opening of the connecting element of said leaf and the lock of the lock. Due to the ability to adjust of latches independently of each other further expands the possibility of configuration of the leaf and the connection element Of the same. It can then be provided, for example, for each latch another lock plate or you can configure each latch differently to increase security against fracture and break-in

The possibility that the measurement of exit of the latches can be solved, for example, by that the lock has at least one rotating lever around of a pivot point, at one end of which it is mounted so tiltable a latch and whose other end is connected with a spindle or thread transmission that can be maneuvered from a outer side of the lock. Spinning the transmission of spindle or thread from the outer side of the lock will displaces, for example, a nut along a spindle or a threaded rod, which causes the lever to swing around of the pivot point. As a consequence of the tilting of the lever, the point of articulation of the latch on the lever is move towards the lock of the lock or away from it.

Another possibility to vary the output measurement of the latches of the lock strike consists, at least in the case of hook mounted latches tiltable, to adjust the coupling element by movement in direction to the opening position or the insertion position or the interlocking position.

As an alternative to this, at least one of the latches can be rotatably mounted on an element of positioning that is linearly mobile in one direction substantially orthogonal to the side surface of the lock, from which the at least one latch comes out. In this case, the positioning element, which, for its position adjustment, it can be in screwed coupling, for example, with a rod threaded, can be moved linearly from the outer side of the lock in the direction of the corresponding lateral surface or moving away from it, which leads to displacement corresponding point of articulation of at least one latch.

Another advantage of coupling the at least two latches by means of the at least one coupling element resides in which the recovery spring element attacks at least one coupling element. Therefore, a single spring element of recovery is enough to replace all the latches coupled with a coupling element. This simplifies considerably the structure of the sliding door lock according to the invention.

In sliding leaf locks that serve to the insertion and interlocking of a sliding sheet, preferably a sliding door, with a connecting element of said sheet, and comprising at least one latch that can move between a insertion position, in which, when the sliding leaf is closed, the at least one latch fits into at least one opening of the element of connecting said sheet in such a way that it blocks a movement of opening of the sliding leaf, and an opening position, in the that, when the sliding leaf is closed, the at least one latch leaves free the at least one opening, the at least one being prestressed latch to its locked position and can be locked in this against a movement towards its opening position, and whose sliding leaf locks feature a locking member that is mobile between a locked position, in which it locks at least a latch against a movement towards its opening position, and a release position in which the movement of the al less a latch towards its opening position, but especially in the sliding leaf locks described above with at minus two latches coupled for movement by means of a coupling element, it may happen that the latch or the sliding door lock latches lock erroneously, the sliding leaf being open, against a movement towards its opening position. When trying to fit then the sliding leaf with the connection element of the same pushing it or pushing it to close it, the latches locked bang against the connecting element of the blade, being able to considerable damage occurs both in the connection element of the leaf as in the lock of the sliding leaf and in the leaf slide. This all the more as a person, who has the insertion capacity of the sliding sheet in the element of connection of the same and does not know that the latches are interlocked, repeat the attempt to fit and eventually push the blade sliding several times and with increasing force against the element of connection of said sheet.

These damages can be prevented when the lock Sliding blade includes insurance against erroneous maneuver that, to prevent the interlocking of at least one or at least two latches, prevents movement of the locking member towards its locking position at least until at least one element of the Sliding blade cooperate for the first time with the connecting element of said sheet when closing the sliding sheet.

Thanks to this insurance against wrong maneuvering you can get an interlocking of at least one or of the at minus two latches by the locking member can occur only when the sliding blade and the element of connection of it have approximated each other in such a way that is imminent or has already taken place an insertion of the latches with the connection element of the leaf.

If you start from the execution form described above, in which the blocking member attacks in the coupling element to lock the latches, it is enough that the wrong maneuver insurance suppresses a movement of the locking member until the at least two latches cooperate with the at least one opening associated with them in the connection element of the sheet. As already described, the latches are moved then by a limiting edge of the at least one opening from its locked position towards its position of opening. In this way, the coupling element that couples the two latches to make a joint move moves linearly from its insertion position, which already prevents an interlocking of the latches because the point of attack for the blocking member, for example the blocking recess, in the coupling element is no longer in the path of movement of the corresponding attack device, for example of the projection, of the blocking member. This happens only when the latches are in their locked position towards which They are prestressed.

In order to realize the insurance against maneuver wrong regardless of the constructive configuration of the sliding leaf lock, the at least one element previously described of the sliding blade can be a proximity probe mobile that stops at the leaf connection element when closing the sliding leaf and that, after making a stop, when the closing movement of the sliding blade, modify its position with relationship to it depending on the distance between the sliding blade and the connection element thereof. The geometric configuration of proximity probe, especially the measurement of your flight with with respect to the side of the lock turned towards the element of blade connection, determine here the distance position between the sliding leaf and the connecting element of this leaf from which is possible an interlocking of the latches.

With this proximity probe you can be coupled for movement a locking means that admits a movement of the blocking member towards its blocking position in function of the position of the proximity probe in relation to the sliding blade Thus, starting from the position of the probe of proximity and, therefore, depending on the distance of the leaf sliding to the connecting element of this sheet, it can be prevented with help of the blocking means a movement of the blocking member towards the locked position. The blocking means can block mechanically to the blocking member itself or to a component of a actuation device of the locking member, for example a closing blade of a profiled bulb.

The coupling for movement between the proximity probe and the locking means may be formed by a gear joint. However, with a view to the simplest constructive execution, the locking member is preferably constructed in one piece with the proximity probe
dad

Also, the movement of the probe of proximity after making this stop on the connecting element of the blade, whose movement modifies the position of the probe of proximity to the sliding leaf while the closing movement of said sliding sheet, can be a sliding movement or a tilting movement. Be prefers in this case a tilt movement of the probe of proximity, since this can be limited to a narrow space around the support point of the proximity probe and, by Therefore, the sliding blade lock can be made in compact construction

When opening the sliding blade by means of a couple of replenishment conditioned by the force of gravity, the probe of proximity preferably mounted tiltingly in the Sliding blade lock can be replaced to the position in the one that blocks the movement of the blocking member towards its lock position However, since then, for example in case of rapid movement of the sliding blade due to forces of inertia, disturbances of the operation of the safe against wrong maneuver, the proximity probe is preferably requested with the elastic force of a spring replacement that, when the sliding leaf is open, replaces it to the blocking position of the blocking member.

In the following the present will be explained invention referring to the attached drawings. They represent:

Figure 7, the embodiment shown in the Figure 5 after insertion of the sliding leaf lock in a closing plate.

In Figure 1 it has been designated in general with 10 a sliding leaf lock according to the invention. Lock 10 Sliding leaf comprises a housing 10 and a strike 14. From openings 16 of the lock 14 of the lock protrude about latches 14 shaped like hooks that are in your insert position. The latches 18 are rotatable around a pivot 20. The pivot 20 is mounted on one end of the lever 24 tiltable around an axis 22 represented in line of strokes The end of the lever 24 opposite the pivot 20 is set as a fork and hugs a nut 26 that is in threaded coupling with screw 28. Screw 28 is subject rotatably, but resistant to displacement, between one side of the lock 14 of the lock facing the mechanism of said lock and a stop 30 obtained by punching and bending of the housing plate. The screw 28 is accessible through a step 32 of the lock 14 of the lock for a drive with tool, for example with a screwdriver. Spinning the screw 28 moves the nut 26 approaching the strike 14 of the lock or away from it. The movement of nut 26 to screw length 28 leads to a lever tilt 24 around its axis 22, whereby the pivot 20 of the latch 18 can move closer to the lock 14 of the lock or moving away from it. The extent to which the latch 18 in its locked position protrudes from lock 14 of the lock.

In each latch 18 two pins are arranged coupling 34 such that the pivot 20 is located in the center of the junction line between the two coupling pins of a latch 18. A coupling pin 34 of each latch 18 is embraced by a respective end section 36 as a fork of a coupling element 38. In a latch 18, in Figure 1 the bottom latch 18, the coupling pin closest to the lock of the lock is embraced by the element of coupling and on the other respective latch 18 the coupling pin 34 furthest from the lock of the lock. It is achieved that the latches 18 move in directions opposite when a linear movement of the element of coupling 38. The coupling element 38 has holes elongated 40 that are crossed by guide pins 42 solidarity of the housing. Guide pins 42 guide the element coupling 38 along the arrow P parallel to the plane of the lock 14 of the lock. Due to the movement of the element of coupling 38 in the direction of the arrow P, the upper latch 18 up and lower latch 18 toward below, that is to say that the latches 18 swing away from one of other. By coupling the other coupling pins respective 34 can be achieved, for the same movement of the coupling element 38, a tilting of the two latches 18 towards each other. You can choose this possibility in case you you want to arrange the latches 18 so that the tips of the latches 18 by way of hooks in their locked position look one out of the other. When engaging with each other the respective coupling pins 34 closest to the lock of the lock or further away from it in each latch 18, the latches 18 may be made to swing in the same direction.

The coupling element 38 is driven to through a nut 44 for the movement of the locking position to the opening position. Walnut 44 presents an appendix of gear 46 that fits into a housing 48 provided for him in the coupling element 38. The housing 48 of the appendix of gear is larger here in the direction of movement of the coupling element 38, that is, in the direction of the arrow P, that the width of the gear appendix 46 in this direction. From This mode provides a slack of movement that makes possible that the latches 18 and, therefore, the coupling element 38 move from the insertion position to the opening position without simultaneous movement of walnut 44. Walnut 44 also presents a quadrangular recess 50 in which the stem fits (not shown) of a manually operated puller 51, such as, for example, a door handle, or the shaft of an electric motor. The shooter of Manual drive 51 is shown in dashed line. The nut 44 presents a control appendix 54 that is in front of the gear appendix 46 with respect to the axis of rotation 52 of the nut and that is coupled with the replacement device 56. The replacement device 56 has a fork 58 that hugs the control appendix 54 and a tension spring 62 connected with the fork 58 and with a spring support 60. If the nut 44 in the direction of arrow N, fork 58 moves upwards and pull spring 62 is stretched. The force spring of traction spring 62 replenishes nut 44, after release it, to the position represented in Figure 1, in which the nut 44 is applied to end stop 92.

The coupling element 38 is prestressed towards the insertion position through an element of recovery 64 comprising a compression spring 66, a support spring 68 on the side of the coupling element and a support of spring 70 attached to the housing. When moving the element of coupling 38 in the direction of arrow P, the compression spring 66 and this one, after releasing the handle of manual actuation 51, replaces the coupling element 38 in the insert position.

Also, the sliding leaf lock 10 It comprises a locking member 72 which is guided by two pins guide 74 along elongated holes 75 in one direction orthogonal to the direction of movement P of the element of coupling 38. Locking member 72 is actuated to movement by the locking pin 76 of a light bulb lock profile 78. This lock 78 is in its position of key removal. In addition, as shown in Figure 1, the locking pin 76 secures the locking member 72 in the position release against a movement towards the locked position shown in Figure 2. Locking member 72 has a appendix 79 of trapezoid shape protruding in direction to the observer from the blocking member 72 located in the drawing plane. Of the two oblique flanks of the appendix of insert 79 trapezoid shape closest to the locksmith of the lock form an insertion site 80 of the position of release and the furthest from the lock of the lock a site of insert 82 of the locked position. In these sites of fit 80 and 82 fits a profiled spring element 84 of conformity with the position of the blocking member 72. Due to the cooperation of the insertion site 80 of the release position, the insertion site 82 of the locking position and the element of profiled spring 84 materializes an superable insert which, in addition to the closing pallet 76, it maintains the member of lock 72 in the respective position chosen. Also, in the locking member is provided a locking pin 86 which in the lock position of lock member 72 fits into a recess of lock 88 of the coupling element 38.

The blocking position of the blocking member 72 represented in Figure 1 is represented in Figure 2. The lock member 72 has been moved to lock recess 88 of the coupling element 38 by turning the locking pin 76 in direction to the strike 14. The profiled spring element 84, which is riveted against the housing 12, is embedded in the site of insert 82 of the locked position. The light bulb lock profiling 78 is again in its extraction position of the key. The closing pin 76 is applied to the blocking member 72 in such a way that a movement of the member is safely prevented lock 72 towards the release position.

It remains to be noted that nut 44 is still fixed in its turning zone by end stops 90 and 92, with that the loads applicable by nut 44 are limited in magnitude both the coupling element 38 and the device replacement 56. In addition, in the example shown it is defined by the cooperation of the end stop 92 and the replacement device 56 a basic position of the manually operated handle 51 represented with dashed line. This shooter 51 is arranged in this case so that the light bulb lock is accessible profiled 78.

In Figure 3 it is represented in the position opening the sliding leaf lock 10 shown in the Figure 1 with latches 18 and coupling element 38. Walnut 44 It is turned in the direction of arrow N to end stop 90. The end section 36 by way of fork is also applied to the stop end 90. The latches 18 have been swung away from one of another and thus release openings 94 of a closure plate 96 which in the interlocking position of latches 18 by way of hooks has been grabbed from behind with these. To illustrate the grip by behind, the tip of the latch has been indicated with dashed line upper 18 in its interlocking position.

Due to the tilt of nut 44, the coupling element 38 has been moved by the appendix of engage in the direction of the arrow P. The lock recess 88 of the coupling element 38 has moved in the direction of the arrow P until the locking pin 86 cannot engage with East. In the opening position of the coupling element 38 no a displacement of the blocking member 72 is possible from the release position shown in Figure 3 to the position of blocking. The tension spring 62 of the replacement device 56 is stretched and, after releasing the drive handle manual 51 together with nut 44, will return said nut to position shown in Figure 1. Also, compression spring 66 of the recovery element 64 is compressed, so that the element coupling 38 will be returned by compression spring 66 to the locking position after releasing the drive handle manual 51.

In Figure 4 another form of Execution of the present invention. The same components as in Figures 1 to 3 are provided with the same symbols of reference, but increased by the number 100. The form of execution of Figure 4 will be described only to the extent that It differs from the previously described embodiment. By otherwise, the reader is referred to the description of Figures 1 to 3.

Figure 4 shows a situation in the that the sliding blade lock 110 moves in the direction of the arrow P towards the closing plate 196 mounted on an element of connection of said sheet, for example a door jamb. The latches 118 stumble in this case, with shaped chamfers 118a built in them in the area of the tips of the hooks, on the edges 198 of the openings 194 of the closing plate 196. Due to the cooperation of the 118a shaped chamfers and the edges 198, latches 118 are swiveled away from one of other. Thus, the coupling element 138 moves towards down in the direction of the arrow P. However, because the dimension in the direction of arrow P of recess 148 for the gear appendix is larger compared to said appendix of gear 146, this appendix of gear 146 of nut 144 is not also moved by the coupling element 138. For this reason, the nut 144 and a manually operated element attached to it remain in the basic position defined by the device replenishment 156 and the end stop 192.

Another difference between the form of execution depicted in Figures 1 to 3 is that the spikes of coupling 134 are provided in the coupling element and they are embraced by coupling recesses 137 of the latches 118. Like the coupling pins 34 of Figures 1 to 3, the coupling recesses are arranged at the same distance of pivot 120, it being provided exactly between the two coupling recess 137 of each latch 118.

In the form of execution represented in the Figure 4 has to, in comparison with the previous one, the capacity to adjust the exit depth of the latches 118 from the openings 116 of the lock 114 of the lock is designed in a constructively different way. As in the embodiment of Figures 1 to 3, a screw 128 fastened in rotating shape, but axially immobilized, is held between the lock 114 of the lock and a stop 130. Figure 4 shows you can completely see only the upper screw 128, since the lower screw 128 is partially covered by the element of coupling 138. A carriage 125 provided with an internal thread is found in threaded coupling with screw 128. By means of Turn of screw 128 can move carriage 125 by bringing it closer to the locks 114 of the lock or away from it. The car 125 it has a flying arm 125a in which the pivot 120 is fixed of latch 118. Therefore, with carriage 125 it is also possible to move latch 118 towards the lock of the lock or away from East.

In the form represented in Figure 4 the blocking member 172 presents in the direction of the arrow P a dimension smaller than in the form of execution shown in the Figures 1 to 3. In addition, the locking pin 186 is provided in the upper end of locking member 172. In the position of interlocking, which is identical to the locked position in the Figures 1 to 4, this spike can be moved into the recess lock 188 of coupling element 138. As is the case already in the form of execution described above, it is useful for this the closing blade 176 of a light bulb lock 178 profiled

Figures 5 to 7 show an embodiment of the sliding leaf lock according to the corresponding invention substantially to the embodiment shown in Figure 4. The same components as in Figures 1 to 4 explained so far they are provided with the same reference symbols in Figures 5 a 7. In this case, the reference symbols in Figures 5 to 7 are have increased by the number 200 with respect to Figures 1 to 3 and with the number 100 with respect to Figure 4. Also, the Figures 5 to 7 will be described only to the extent that they contain components that have not been explained in relation to one of the Figures 1 to 4. Otherwise, the reader is expressly referred to the description of Figures 1 to 4.

The sliding leaf lock 210 comprises a device against wrong maneuver that prevents it from being open the sliding blade, the latches 218 can be locked against a movement from its locking or interlocking position to its opening position This device against wrong maneuver comprises a proximity probe 203 substantially in shape triangular which is mounted on a guide pin 242 with possibility of swinging around it. A tip 203a of proximity probe 203 protrudes from an opening 217 of the lock 214 of the lock. In proximity probe 203 is provided, orthogonally to it, on the far side of the observer of Figure 5, a stop 205 that is applied against the inner side of the lock 214 of the lock. This stop is pressed against said strike by the elastic force of the spring 207. The spring 207 it is supported with a flown arm 207a at the end stop 292 of the nut 244. The flown arm 207a has a spring section 207b of helical shape surrounding another guide pin 242 different from the above-mentioned. This guide pin 242 keeps the spring 207 on your site.

The spring section 207b of helical shape carries in turn joined a blown arm restocked 207c whose extreme area it is applied to the side of the proximity probe 203 opposite the tip 203a and thus press the stop 205 of the proximity probe 203 against the inner side of the lock 214 of the lock and keeps to proximity probe 203 in the position shown in Figure 5.

The position of the proximity probe 203 is here such that a vertical line drawn from tip 203a in direction to the lock 214 of the lock, that is, in the direction contrary to the direction of arrow B, it does not cut the guide pin 242 proximity probe support 203. Thus, when the tip 203a abuts the wall 298 of the closure plate 296 at close the sliding leaf, you have to continue moving of closing, a pair of turn that moves this proximity probe 203 into the housing 212 of the lock 210 of the sliding leaf.

In the corner of the proximity probe substantially triangular in shape that is closer to the member lock 272 is formed a lock extension 209 with the colliding the locking pin 286 of the locking member 272 in in case an interlocking of the leaf lock is attempted slide. Therefore, it is not possible to move lock member 272 by means of the closing pin 276 of the light bulb lock 278 profiled to bring it to its locked position, that is to say you can insert the locking pin 286 into the locking recess 288 of the coupling element 238 in both the probe of proximity 203 meets the extension 209 lock in the locking position shown in Figure 5.

In Figure 6 the action of blockage of the extension of blockade 209. The closing pallet 276 can be spun with simultaneous drag of the locking member 272 until locking pin 286 is applied to the extension block 209. If the pallet is requested with additional force lock 276 by means of a key (not shown) inserted in the profiled bulb lock 278, this only leads to that the stop 205 be applied with greater pressure against the inner side of the lock 214 of the lock.

On the other hand, the function of the wrong maneuver insurance is not impaired by the effect of the blocking member applied to the locking extension 209, at least when the key has been released in the profiled bulb lock 278 when pushing or driving the sliding blade to close it In the event that the tip 203a of the proximity probe 203 abuts a connecting element of the sheet, for example in the wall 298 of the closing plate 296, and the sliding sheet or the lock 210 of said sheet moves further in the direction of arrow B, the proximity probe is then tilted into the housing 212 of the lock 210 of the sliding blade, exerting the locking extension 209 a force on the locking pin 286 applied to it and pushing to the locking member 272 to return it to the position shown in Figure 5. In case the closing movement still continues, the locking extension 209 is made to swing to a greater extent and, finally, free the movement of the member of lock towards the position of
blocking.

The lock is shown in Figure 7 210 of the sliding leaf embedded with the closing plate 296. The proximity probe 203 is applied with its tip 203a to the wall 298 of the closing plate 296 and has been tilted into the housing 212 against the force of spring 207. The movement of tilt of the proximity probe 203 produces a displacement of the blown arm replaced 207c of the dock 207.

In this position the locking extension 209 it is tilted in such a way that it admits a movement of the spike lock 286 of lock member 272 into the recess of lock 288 of the coupling element 238. Accordingly, the lock member 272 can be brought to its locked position, in which it latches the latches 218 embedded with the sheet of close 296 against a movement towards its opening position.

If, in the unlocked state, the latches 218 by means of nut 244 towards its opening position and the sliding leaf is opened, so that the lock 210 of said Sliding blade moves away from the closing plate 296, the spring 207 resets the proximity probe 203 to the position shown in the Figure 5, which suppresses an interlocking of the latches 218.

Another difference between the way of execution of Figures 5 to 7 and the embodiments of Figures 1 to 4 resides in the constructive execution of the recovery element 264 and of the replacement device 256. In the replacement device 256 a compression spring 263 is used as a spring replacement. At its end turned towards the nut 244 the spring of compression 263 rests on a spring support 260 integral with the Case. The fork 258 that hugs the control appendix 254 features a flown arm that hugs compression spring 263 and forms a spring support 259 on the fork side for the end of compression spring 263 looking out from the nut 244

On the contrary, the recovery element 264 employs a traction spring 267 which, with a conformation in a manner of spring wire ring at its two ends, it is hooked on a spring support 268 on the side of the element coupling and on a spring support 270 integral with the Case.

When turning nut 244 in the direction of the arrow N to move the coupling element 238 in the direction of the arrow B and therefore to move the latches 218 from its insert position, which is represented in Figure 5, until its opening position, tension spring 267 of the recovery element 264 and the compression spring is compressed 263 of the replacement device 266. Yes, after opening the sliding blade, the drive element is released again manual (not shown in Figure 5) attached with nut 244 to perform a joint movement, the reset device 256 causes the nut 244 and therefore the drive element manual and recovery element 264 return the element of coupling 238 to the position shown in Figure 5.
