Description

The invention relates to the castle "Anti-panic" according to the restrictive part of paragraph 1 of the claims.

From the application EP 0668425 a door lock is known, the latch and the latch of which can be retracted with the help of a push door handle and a lock sleeve connected to it by means of a drive connection. The valve is actuated by means of a pusher tending by the force of the spring to the closed position and held by the release device in the open position. To connect to the valve, the pusher is equipped with a link, which includes the valve pin. The axis of the lock sleeve is paired with the pusher, due to which the valve is actuated together with it. A special locking device for diverting the valve back is not provided, with the exception of the backstage segment located in the push rod transverse to the valve movement in the direction of closing and opening.

From the applications DE 3520862 and DE 3537786, there are known versions of the lock in which the main lock box includes a latch and a latch, as well as a pusher equipped with drive rods, connected by means of a drive connection to the drive rods protruding from the housing of the main lock box. Correspondingly to the drive rods, auxiliary lock boxes and / or locking elements are located which, by means of the drive rods, move into or out of the slots for the gate valves. The pusher with the drive rods is equipped with a locking device, which, when the valve is in the locked position, does not allow the pusher to move under the influence of the drive rods. The goal is to prevent the lock from being unlocked when a potential cracker tries to move the drive rod with a tool. Without a locking device, under the influence of a pusher equipped with drive rods, the latch of the main lock box, as well as all other locking elements and / or auxiliary locks located on the drive rods, will also move to the opening position, which will allow an outsider to open the sash.

In the above-mentioned known embodiments, the locking device is formed by a rotary locking lever. In DE 3520862, a locking surface is provided on the locking lever adjacent to the hook hole. The locking lever interacts with the distribution pin of the pusher, which is moved in the open position of the lock by means of a locking cylinder by means of a drive mechanism, and removes the hole of the hook from the area of the locking protrusion fixed in the housing, which unlocks the pusher equipped with drive rods. In the application DE 3537786, on the contrary, it is provided that the locking lever by means of a distribution pin actuates one of the gears.

A lock is known from DE 3148030, in which a pivot arm can correspond to a push rod equipped with drive rods, which, when the valve is in the extended position, rests with the locking faces on the push rod equipped with drive rods and abuts the locking recess in the locking protrusion from the housing side.

DE 3034764 proposes a pivot lever located on a push rod equipped with drive rods, which, when the gate valve of the key lock box is extended, moves into the area of the counter-motion motionless located in the housing, which does not allow the drive rod to move in the opening direction, and which, when the gate valve is retracted, is again withdrawn from the specified zones.

A disadvantage of the embodiments known from the prior art is that in all of the above embodiments, an unlocking method is provided based solely on the use of cylinders. Thus, their use in door locks controlled by a push handle seems impossible.

The objective of the invention is to develop the design of the lock, driven by a push-pull door handle and detects a high degree of protection against squeezing the drive rods.

The lock solution in accordance with the invention provides that the locking device is formed by a locking protrusion located on the variable pressure element, which in the locked position of the valve prevents it from moving in the direction from the extended position.

The form of execution of the invention involves only a small number of additional structural elements that can easily be placed inside the main lock box.

The simplest improvement option provides that the locking device consists of a locking protrusion slanted towards the valve, which in the locked position enters the locking recess.

Reliable locking is ensured in a situation where the variable pressure element detects a guide pin that is adjacent to the housing protrusion and mates with the housing, and which supports the variable pressure element in the housing.

An advantage is also that a trigger device is provided in the valve or on the valve, which can move in the valve against the action of the energy storage device in the direction of the unlocking position and grab with it an alternating pressure element when unlocking.

In addition, it is provided that the trigger device is a pusher moving in the direction of locking.

The invention is illustrated by drawings.

In FIG. 1 shows the main lock box 1 of a multi-level locking device, which, by means of protruding rods 2, 3, protruding from the main lock box 1, actuates other locking elements not shown here, along with the latch 4 and the main lock latch or latch 5. These are not shown the locking elements may also be locking elements located in the auxiliary lock boxes or located directly on the drive rod 2, 3 and movable with it elements that are in the closing position are respectively located on the frame slots for valves. The drive rods 2, 3 are moved along the guide of the front plate 6.

Inside the housing 7 of the main lock box 1, the drive rods 2, 3 are connected by means of a drive connection, using a pusher 8 equipped with drive rods and simultaneously connected to the drive device of the main lock. The lock sleeve 9 contains the axis of the sleeve 10, which when turning abuts against the regulating slope of the pusher 8 equipped with drive rods and moves it according to FIG. 1 upwards, and on the other hand, the same axis of the sleeve 10 is coupled to the variable pressure member 30. The latter is located according to FIG. 1 above the pusher 8 equipped with drive rods and is elongated by an arm 31 towards the axis of the sleeve 10, while the extension 32 protrudes in the rotation range of the insert gear 26, which is coupled to a locking cylinder not shown here. Turning the gripper lead clockwise entails moving the variable pressure member 30 up in the direction of arrow 33.

As shown in FIG. 2, the variable pressure element 30 is equipped with a base 34 located opposite the bracket 31 and extension 32. This base 34 is located in the valve zone 5 and forms a fork 35 by the bracket 31 and the protrusion 36. The protrusion 36 forms due to the regulating slope vertically located to the plane of the variable pressure element 30 37 the locking face 38, which is associated with the valve 5 in the locking recess 39. The locking face 38 and the locking recess 39 together form a locking device 40 and prevent when the valve 5 is retracted back in the direction opposite the direction of extension 41. Thus, the locking device 40 is locked by a latch 5 against movement in the direction opposite to extension 41, if the latch is in the latched position.

In addition, with the valve 5, the pin 23 is locked in the locked position and is included in the recess 24 of the valve 5. The pin 23 is fixed on the push rod 8 equipped with the drive rods and moves with it in the locked position down according to the drawing, due to which it enters the recess 24. The valve 5 is coupled with a pusher 8 equipped with drive rods by means of a Z-shaped link and a trunnion included in it. In the locked position, the trunnion is located in the backstage segment parallel to the direction of movement of the pusher 8 equipped with drive rods, due to which, on the one hand, it is difficult to slide the valve 5 back, and on the other hand, the pusher 8 equipped with drive rods can move to unlock some distance without movement of the valve 5. Due to this, the pin 23 can be extended from the recess 24 before the valve 5 moves in the opposite direction to the extension 41.

As described above, it is envisaged that the locking device 40 consists of a locking face 38 which is tapered towards the valve 5 and which, in the locked position, enters the locking recess 39 of the valve 5.

To ensure reliable engagement of the variable pressure element 30 on the valve 5, the variable pressure element 30 is moved next to the locking face 38 by means of a guide pin 42 connected to the housing 7 or the lock cover in the longitudinal hole, which makes it difficult to move the variable pressure element 30 when the valve 5 is biased In this regard, it seems advisable to design a variable pressure member 30 in the form of a pusher moving in the housing approximately parallel to the push rod equipped with drive rods. This gives a relative to the direction to the locking 41 stroke enclosing the guide pin trunnion in the housing 7 or the cover of the lock.

The principle of operation of the above form of execution is as follows. If the lock locked according to FIG. 1 or 2, is driven by a push handle, that is, by a pivoting movement of the lock sleeve 9, then the axis of the sleeve 10, as well as the push rod 8 equipped with the drive rods and the variable push element, are moved up according to the drawing. The engagement of the pin 23 in the recess 24 is disengaged, as is the engagement of the locking face 38 in the locking recess 39. The pusher 8, equipped with the drive rods, provides for the retraction of the valve 5. When connected with the pusher 8 equipped with the drive rods, the connecting elements as well as the locking elements located on them or auxiliary locks are moved by means of drive rods 2, 3 to the opening position. At the same time, the latch lever 43 moves back the spring-loaded latch 4. The shutter is unlocked.

When acting on the locking cylinder, as shown in FIG. 4, by means of an insertion gear 26, the variable pressure element 30 is moved upward, which ensures that the engagement of the locking face 38 in the locking recess 39 is disengaged. The pusher 8 equipped with drive rods also moves, producing the above-described action on the drive rods 2, 3 and on the axle 23. Variable the pressure element 30 subsequently causes a pivoting movement of the latch lever 43, which allows the latch 4 to be pulled back.

Both of the above methods of action thus lead to unlocking the sash when exposed to both a key and a push handle.

One of the improved forms provides according to FIG. 5 is a design in which, along with the aforementioned functions, a release device 45 is provided in the valve 5. This release device protrudes forward at the end 46 of the valve 5 and is associated with a release device, for example, a closed or non-passage valve, coupled with the navigation valve. In this case, the valve 5 extends forward into the locking hole of the locking device coupled to the non-passage leaf, which, when opened in a known manner, retracts the valve 5 of the running leaf from the locking hole. To enable the manipulation of the valve 5, the above-described locking device located on the valve is provided. However, this locking device 40 may open under the influence of the trigger device 45.

For this purpose, the trigger device 45 is made in the form of a pusher that moves against the action of the energy storage device in the direction of the unlocking position, that is, in the direction opposite to the extension direction 41. The trigger device 45 is connected via a drive connection to a rocker mounted laterally on the valve across the extension direction 41. 47 in such a way that the movement of the trigger to the right according to the drawing entails the upward movement of the rocker 47. Rocker 47 and the thrust pressing element 30 is interconnected by means of a drive connection, which enables the upward movement of the variable pressing element 30 and, accordingly, the locking device 40 is unlocked. In this case, the pusher 8, equipped with the drive rods, is moved by means of a groove in the rocker stone 47, into which the pin 23 enters an opening position in which the pin 23 releases the valve. A further retraction of the valve 5 by means of a locking device of the non-passage leaf provides continued movement of the pusher 8 equipped with drive rods.
