BACKGROUND OF THE INVENTION The present invention relates to a locking device comprising a locker assembly comprising a tray, a lid and an expanded front panel, a latch located inside the locker and partially extended therethrough by opening the front panel, and a locking device, e.g. comprising a locking insert and an actuator inserted between the latch and the locking means, the rear end of the latch having a locking zone, at least one primary locking member of the locking zone, and also at least one secondary locking member and one or more receiving openings thereof the actuator is provided with an intermediate assembly and a lever, and the lever is connected to a lifting surface temporarily in contact with the closure for moving the lever up.

• · ·

The increased aesthetic requirements for the various door and window structures that cover the openings made from new structural materials created by the development of the industry have also significantly influenced the safety needs of the locking systems used in doors and windows.

Nowadays, it is increasingly important that the latch is as thick as possible and that it can be pushed out of the closet as long as possible, while having the closest possible structural depth. This requirement is particularly pronounced in the field of so-called portal locks, but of course it is a requirement for other locks, eg. including locking locks, screw locks, landscape and portrait versions. Of course, with these requirements, the difficulty of opening and unlocking the lock remains an essential consideration.

A number of constructions have been developed to meet new demands. A large part of these are actuated by actuators assembled from different motion transmission elements in the locking cabinet. Examples of such latches include, for example, / 4.118.480, 3 ^ .019.350, and c.

However, they have the disadvantage that the cabinets are large in size and the components that operate the latches are complicated, making them expensive to manufacture and time-consuming to assemble.

A further disadvantage is that due to the wear and possible tension of the parts moving relative to one another, there is a great potential for failure.

It is furthermore disadvantageous that the positioning of the latch actuating parts can be achieved only by reducing the latch thickness, which in turn greatly reduces the strength and resistance of the latch.

beat

A narrower cabinet is subject to the construction described in U.S. Patent Publication Nos. A3.427.713, \ 3.316.261 Dt, and '3.037.018.

• · «

- ο However, here too, wear and tear on the moving parts and the consequent failure of them are unfavorable.

They also have the disadvantage that although the depth of the closet is significantly reduced, the complexity of the moving mechanisms used in the structures increases.

A common disadvantage of most known solutions is that, despite their original function, they can be unlocked by simple means and operations, due to the small cross-section of the latch or the removability of moving parts.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the shortcomings of conventional locking devices provided with a locking sleeve which makes it difficult to dislodge the latch, and to provide a design that incorporates a simple latch moving mechanism despite its small structural depth.

It was also our intention that the reduction of the depth dimensions should not result in an increase in other dimensions of the closure, and that the latch protrusion and cross-section would remain at least as usual with conventional constructions and that the lock would be reduced by unauthorized persons. also the possibility of opening it to a minimum.

The inventive idea was based on the recognition that the conventional lever can be adapted to move the latch directly, subject to appropriate modifications. In fact, if the lever is made with a particular geometric design, taking into account the movement path of the lock insert, and unlike the known designs, the lever is specially forced to engage with the latch, then the task can be solved.

In accordance with the object, the locking device according to the invention, comprising a locker consisting of a tray, a lid and an expanded front panel, is located inside the locker and can be partially extended therefrom by opening the front panel.

a lock and a locking device which can be inserted into the locker, e.g. comprising a locking insert and an actuator inserted between the latch and the locking means, the rear end of the latch having a locking zone, at least one primary locking member of the locking zone, and also at least one secondary locking member and one or more receiving openings thereof the actuator is provided with an intermediate assembly and a lever, and the lever is in contact with a lifting surface adapted to move the lever upwardly and temporarily in contact with the locking device, such that the locking device is operable with the locking device a recessed surface located on its opposite side and in contact with it is temporarily assigned.

A further feature of the locking device according to the invention may be that the lever has a carrier body having a breakthrough at least partially enclosing the locking device, the lifting surface and the sinking surface being disposed along the break and extending from the carrier body.

t

In an embodiment, it is advantageous that at least one of the latch and lever is provided with a guide track and the other is connected to a guide member and is part of the transmission assembly, and is thus connected to the lever for a forced engagement.

In another embodiment of the locking mechanism, the guide track is formed of a main intermediate section corresponding to the direction of movement of the latch and a first inclined section which extends at one end of the intermediate section and is inclined at an angle to the intermediate section. The guide track is completed by a second oblique section which is inclined to the other end of the intermediate section and is inclined at an angle to the intermediate section.

In another embodiment, the first oblique section and / or the second oblique section of the guide track have a support surface.

In a further embodiment of the invention, the actuator is a actuator having a single guide pin.

In a further advantageous embodiment of the locking mechanism, the lever has a hook member which prevents the movement of the latch, and the latch is provided with a stop member which leans against the hook member.

The present invention has many advantageous features. Most importantly, while maintaining the usual size of the locker, it is possible to significantly reduce the depth - both for portal locks and notch locks - so that the latch actuating mechanism can be much simpler than the commonly used versions for lever locks.

A further advantage is that due to the completely different design of the lever and the novel lock-lever constraint, despite the small closure depth, both the rotation of the latch in one revolution and the structural thickness of the latch may exceed known designs. This, in addition to improving the aesthetic appearance of such doors and windows, also greatly enhances the security of the lock against burglary.

It is also an advantage that due to the small number of moving parts, the tension, wear and consequent failure of the locking mechanism are reduced and their operation is made more reliable.

It is also advantageous that the locking device according to the invention can be manufactured by conventional technology and at a lower cost than other levered locking devices.

The invention will now be described in more detail with reference to the drawings, in which: In the drawings it is

version, which in this case is a conventional engraving lock. The closet 1 comprises a tray 1a with a lid 1c and a front plate 2 on the latch side 5 of the closet 1.

The tray 1a and the lid 1c of the closet 1 are held together by the fastening elements of the lid which are connected to the screw housings 1b fixed in the tray 1a via the through arrows of the lid 1c ld.

Figure 1 shows the trap 4a and the trap 4, which can be moved in a manner known per se by the nuts 3, projecting from the face 2.

head trap. The portion not covered by the lid shows how the locking device 7, which in this case is the locking insert 7a, is located in the locker 1.

Although the locking device of Fig. 1 includes the walnut 3 and the trap 4 for completeness, this is not a necessary requirement but does not affect the substance of the solution. It should also be noted that for the sake of simplicity in understanding the construction of the locking device according to the present invention, certain parts that are not relevant to the solution are not shown in Figure 1 in order to better visualize the connection and location of the essential members.

Figure 1 illustrates how the lever 81 of the actuator 8 surrounds the locking insert 7a. The lever 81, as seen in Figure 2, is comprised of a carrier body 81a, a puncture 81d penetrated into the carrier body 81a and adapted to pass through the locking insert 7a, and a curved upper lifting surface 81b on the carrier body 81a. - comprising a recessed surface 81c which is divided into two parts by the outer channel 812d of the break-through 81d. .

The opening 81d here includes an inner opening 811d for receiving a locking insert 7a in the form of a cylinder lock and an outer channel 812d forming a continuation thereof, where the outer channel 812d protrudes to the edge of the carrier body 81a.

Also, the carrier body 81a of the lever 81 has a guide track 9 formed from a substantially horizontal intermediate section 9b and a first oblique section 9a connected at an angle 91b to one end of the intermediate section 9b and forming a continuation of the other end 92b of the intermediate section 9b. a groove-like recess formed by a second inclined section 9c inclined at an angle of the same.

In this embodiment, the guide track 9 is formed in the first oblique section 9a and the second oblique section 9c of moving the latch 5 externally, e.g. also a support surface 9d, which prevents pushing and pinching.

·· ·· • · ·

Returning now to FIG. 1, it is also observed that the size of the piercing 81d in the body of the lever arm 81a is adapted to the size of the locking insert 7a such that the width of the inner opening 811d follows the width of the locking insert 7a.

However, the inner opening 811d is larger in vertical direction than the locking insert 7a, which allows the lever 81 to move in a vertical direction, i.e. rising and lowering with respect to the locking means 7.

In Fig. 1, the dashed line illustrates the actuator assembly 82, of which the actuator 82a is a guide pin 821a. This guide pin 821a extends into a guide path 9 formed in the carrier body 81a of the lever 81. The actuator 8, formed from the lever 81 and the intermediate assembly 82, thus engages the latch 5 and the locking means 7.

It is also shown in Fig. 1 that the latch 5 comprises a latch head 5a extending from the closet 1 and a latch body 5b remaining inside the closet. In this variant, the rear 51b of the rer test body 5b is provided with a connection zone 6 which contains a primary switch member 6a, a secondary secondary member 6b and a single receiving opening 6c enclosed therein.

It should be noted here that both the primary switch member 6a and the secondary switch member 6b - and hence the receiving opening 6c - may be more.

In the operation of the embodiment shown in Figures 1 and 2, the crank 71a is also rotated by rotating the locking insert 7a and pressing against the lever surface 81b formed by the lever body 81a with its outer surface 711a. As the crank 71a is moved further, the crank 71a begins to raise the lifting surface 81b and thus the lever 81.

The upward movement of the lever 81 also forces movement of the guide path 9 formed in the body of the lever 81.

The first oblique section 9a at one end 91b of the intermediate section 9b of the guide track 9b starts upwards and is thus depressed. Due to the open position of the 5 latches - the guide pin 821a resting in the first oblique section 9a. Guide pin 821a begins to slide on the upwardly inclined first portion 9a while moving toward intermediate portion 9b of guide track 9, thereby extending the locking head 5a of the latch 5 as it expands the front panel 2a of the closure.

With properly selected geometric dimensions, the receiving opening 6c of the engaging zone 6 formed at the rear 51b of the latch body 5b of the latch 5 arrives above the rotating spindle 71a of the latch 7a when it just leaves the secondary engaging member 6b.

At the same time, the guide pin 821a reaches the end of the first oblique section 9a and at one end 91b enters the retrograde intermediate section 9b where it can proceed without hindrance.

From now on, the locking insert 7a is moved further, viewed from right to left, as shown in FIG. 1, by the crank 71a engaging in the receiving opening 6c of the connection zone 6.

f

The forced engagement of the crank 71a with the latch 5 lasts until the crank 71a reaches its left-most position and turns away from the receiving opening 6c of the connection zone 6. At this point, however, the guide pin 821a, which is a transfer member 82a of the intermediate assembly 82, reaches the other end 92b of the intermediate section 9b of the guide path 9 and, upon entering the second oblique section 9c of the guide track 9, rests on its wall.

The locking insert 7a rotates further during its crank 71a and now strikes it against the lowering surface 81c of the lever 81. Due to the downward force exerted by the crank 71a, the lowering surface 81c of the lever 81 is moved downwards. Due to its shape, the second oblique section 9c of the guide track 9 traveling with the downwardly moving lever 81 further pushes the guide pin 821a protruding from the rear portion 51b of the latch 5 towards the left. Finally, when the lever 81 is fully lowered to its original lower position, the latch head 5a of the latch 5 is completely ejected from the closure 1.

«·« «

10, it will be appreciated that by working together the guide surface 9b and the lifting surface 81b of the lever arm 81 and the lowering surface 81c, the lock 5 will travel substantially longer than the crank 71a and the crank 5 in a single rotation. could be derived from the feed of the latch during its connection time.

A further advantage of the construction is that, when the latch 5 is extended, the crank 71a rests on the lower surface 81c of the lever 81 and prevents it from rising. However, because of this stable position, the guide pin 821a protruding from the latch 5 and resting on the support surface 9d in the second oblique section 9c of the guide track 9 of the lever 81 cannot be pushed back into the closure 1.

When the latch is opened as shown in Fig. 1, the process described above takes place in the reverse direction, except that the latch 5 moves from left to right. At the end of the process, the latching head 5a of the latch 5 is again in the locking cabinet, and the guide pin 821a of the actuator 8 is mounted at the upper end of the first oblique section 9a of the guide track 9.

Figures 3 and 4 show a partially different locking mechanism. However, this embodiment also includes a lever 81 and an intermediate assembly 82 of the actuator 8. The lever 81 has a lifting surface 81b formed on the support body 81a and a lowering surface 81c as well as a breakthrough 81d. Here, too, there is the guide track 9 and the first oblique section 9a, the intermediate section 9b and the second oblique section 9c constituting it.

However, the basic difference is that the lever arm 81 includes both the shoulder hook member and the spring support 81f. Another difference is that while in the previous case the 31 lever was a powder metallurgy component, in this version the 81 lever was made of sheet metal.

Consequently, the lowering surfaces 81c at the bottom of the body 81a of the lever arm 81a are bent from a sheet so that their surface is flat. However, this does not adversely affect proper operation.

Here, as in Fig. 1, the movable member 82a of the transmitting assembly 82 is a guide pin 821a that fits in the guide path 9 of the lever 81 and is supplemented by the auxiliary pin 822a.

The guide pin 821a is located on the inside of the latch 5, so it is only indicated by a dashed line, while as a continuation thereof, the auxiliary pin 822a is coaxial on the outside of the latch 5 with the guide pin 821a.

Figure 3 also shows that the upper part of the latch 5 is completed with a stop member 5c, which in this case is a barrier 51c comprising a recess 52c.

The operation of the locking device of Figure 3 takes place in substantially the same process as in the case discussed above. The difference is that it also performs a tilting motion when the latch 5 is extended, since the lowest point of the primary switch member 6a of the connector zone 6 located at the rear 51b of the latch body 5b is lower than the top of the latch 7a. Thus, as crank 71a is rotated, it actually lifts the bottom of the primary engaging member 6a of the connecting zone 6 above the locking insert 7a. The auxiliary pin 822a controls the tilt, which, by running in a cut-out lf formed in a cut-out lf formed in the cover of the closure 1 (not shown), causes the latch 5 to be tilted.

A further difference in operation is that when the crank 71a has already pushed the latch 5 forward in the process of pushing the latch 5, the crank 71a is rotated out of the receiving opening 6c of the attachment zone 6 and has also left the lifting surface 81b of the lever 81. and a spring 10 placed between the closet 1 pushes the lever 81 back to its home position.

* · <· ··· • «· · * • 4 · · · • · ♦ ·

12 The hook member 81e then sinks slightly behind the barrier 51c and stops it, preventing the latch 5 from slipping back. However, this spring 10 is preferably not strong enough to force the lever 81 back into its lower position while it is pushed forward by the guide pin 821a inserted into the guide track 9. Here, too, the reimbursement is effected by the cooperation of the lowering surface 81c of the crank 71a and the lever 81.

Again, when the latch 5 is extended, the crank 71a sits on the lower surface 81c of the lever 81 and holds it in a lower position, preventing the latch 5 from being pushed back. The same purpose is provided by the hook member 81e, which is supported by the barrier 51c, and by the guide pin 821a which is pressed against the support surface 9d formed in the second oblique section 9c of the guide track 9c.

Again, an example of a different embodiment is shown in FIGS. set of figures. As illustrated in Fig. 7, the transfer member 82a of the transfer assembly 82 is made of a collecting plate 824a, a guide pin 821a on one side of the collecting plate 824a, and one of the movable pins 823a disposed adjacent to the holding pin 821a. 822a.

The latch 5 of Fig. 8 is also of special design, since the grooves 5e, the recess 5f and the hole 5g are inserted into the rear part 51b of the latch body 5b of the latch 5b.

Fig. 9 shows the lever 81 having a raised surface 81b and a lowering surface 81c here formed by curved and straight ribs projecting from the supporting body 81a. Also, the carrier body 81a of the lever arm 81 includes a plurality of guide tracks 9.

As illustrated in Figures 5 and 6, the locking cabinet 1 of the locking mechanism formed as a portal lock is substantially the same depth as the combined length of the locking head 5a and locking body 5b of the lock 5. However, the construction of the invention can be used well in this case as well.

The primary switch member 6a and the * * · located in connector zone 6

The secondary switch member 6b is slidably inserted in the grooves 5e of the latch 5, while the primary connector member 6a is moved by one of the movable pins 823a of the transmission member 82a of the transfer member 82a and the second connector member 82 mover pin connected. Between the primary engaging member 6a and the secondary engaging member 6b, through the hole 5g in the recess 5f, the guide pin 821a passes through the guide track 9 of the lever 81 and then through the tray 1a of the closet 1 as shown in FIG. lf also cut.

The moving pin 823a on the collecting plate 824a of the transfer member 82a runs, as shown in Fig. 10, in a curved cut-out lf formed in the lower cover of the closure 1, which is also a forced path to control the movement of the collecting plate 824a.

In the embodiment shown in Fig. 5, the actuator assembly 82 not only acts as a transmitting force between the lever 81 and the latch 5, but also controls the respective positions of the primary switch member 6a and the secondary switch member 6b during the closing and opening operation. And, by its guide pin 821a, ensures that the lock 5 is movable in its end positions.

The operation of this variant differs from that shown in Fig. 1 in that the primary switch member 6a and the secondary switch member 6b are controlled by the primary switch member 6a and the secondary switch member 6b when moving the crank 71a of the locking member 7a, how the position of the crank 71a requires it.

11-13. Figures 1 to 8 show further possibilities for the formation of the transmitting assembly 82 and also illustrate that the transmitting assembly 82 serves not only to create a forced connection between the lever 81 and the latch 5, but also to move the elements of the connection zone 6 as needed.

In Fig. 11, the intermediate assembly 82, e.g. the wings 825a having wings for displacing the primary link member 6a and the secondary link member 6b. Reimbursement of these parts shall be subject to the provisions of Article 11.

so-called concealed springs.

In the embodiment of FIG. 12, the transmitting assembly 82 moves the Iris forming the coupling zone 6 as a mechanical transmission.

Moreover, as illustrated in FIG. 13, the mediator assembly 82 may itself perform the function of a primary switch member 6a, a secondary switch member 6b, and a receiving opening 6c of the connection zone 6 itself.

The locking device of the present invention is well suited for all applications requiring a low depth of installation, a high locking action and a reliable locking device.
