Abstract

The invention relates to a lock (1) to be used, in particular, on doors of apartments, in particular a lock (1) which can be actuated by a drive rod, which lock divides up the locking position to the frame-side striking plate (44) by subdividing the bolt-member movement, this resulting first of all in the bolt moving forwards by a tightening movement made possible by a bolt bevel and, subsequently, a bolt interconnecting engagement to the striking plate (44). For the purpose of optimising the closure method, the invention proposes to provide two mutually adjacent bolt members (A, B), of which one bolt member (B), exhibiting the bolt-member bevel (37), is controlled such that it leads during the closure movement. On the other hand, the bolt member (A) causing the interconnecting engagement [lacuna] via a pivot member. <IMAGE>

From DE 40 06 687 A1, embodiments of such a lock are known. One embodiment includes a hook-shaped locking element that advances linearly over the cuff during the locking process and which, after the locking element has advanced, pivots downwards to provide a rear grip on the frame side.

Furthermore, the hook bolt engages with a control pin in a control slot of an actuating slide that is guided longitudinally in the lock housing. The slot section used to control the hook bolt , into which the control pin is inserted.

The object of the invention is based on the task:

|. - ■.'.■■· to design a lock of the type in question in a way that is simpler to manufacture and more cost-effective in terms of locking technology. '

' Two differently acting bolts are now provided, which are driven by a common drive element. The drive is carried out via a

Once the door has been tightened and has completely entered the strike plate on the frame side, the other locking element comes into engagement by means of a pivoting movement. This takes place completely without hindrance, apart from the normal friction at the joint point of this locking element. Furthermore, this creates increased security, in addition to the engagement by means of the locking element being bevelled, the locking element, so that an attempt to break open is made more difficult.

' that the locking member with the bevel is

linearly extending mandrel. A circular cross-section for the mandrel is particularly suitable. Accordingly, the corresponding strike plate recess can also be designed as a circular hole. The bevel is then to be designed as a flattened area. For example, it is possible to have a blunt-shaped

To limit the protrusion of the hook bolt, it is intended that it has a stop that protrudes into the hook mouth and, in the closed position, hits the back surface of the cuff. Thus, the

In the embodiment, the lock 1 is part of a drive rod lock 2. This has a central lock 3, which is attached to a longitudinal cuff 4. The latter is also the carrier of the lock 1, which, in the embodiment, fulfills the function of an additional lock. In the embodiment

VGN: 258 024 A 20 989 Dr.G./We. 7.1:1998 . .

Such an additional lock 1 is provided above the central lock 3. An equivalently designed additional lock is arranged below the central lock, which is however not shown.. -

Regarding the central lock 3, it is a

■ ■" · '.'' Mortise lock with latch 5 and bolt 6. The latch 5 can be retracted using a follower 7. The latch 5 can also be retracted using a locking cylinder 8 built into the central lock. The latter also serves to lock the bolt 6. Two complete locking turns of the key 9 inserted into the locking cylinder 8 lead to a complete advance of the bolt 6. Along with the forward locking movement of the bolt 6 , the drive rods 10, 11 running behind the faceplate 4 are displaced. -

The lock 1, which serves as an additional lock, has in detail a lock base 12, which is fixed to the back of the cuff 4. A lock cover 13 extends parallel to the lock base 12. Fastening screws 14 are used to hold it, which engage in studs 15, 16, 17 on the lock base. An actuating slide 18, which runs in the longitudinal direction of the lock, rests on the lock base 12'. Its rear edge 18' extends to a rear narrow wall 19, which is angled away from the lock base 12 and runs parallel to the cuff 4. The middle stud 16 extends through a . parallel to the cuff 4. directed longitudinal slot'20 of the operating slide 18. In the lower area, the latter is coupled to the drive rod 10, which engages with an angled end 10' in a transverse slot 21 of the operating slide 18 that is open at the edge. The aforementioned transverse slot 21 starts from the front edge 18'' of the operating slide 18.

The lower stud 17 forms the pivot pin for a locking member A. This is designed as a hook bolt 22, has a single arm and forms a hook mouth 23. This creates the locking hook 24 at the end, which creates a composite engagement when closed. When the hook bolt 22 is in the open position, it rests on the narrow wall 19 with its rear edge 25, while the locking hook 24 is flush with the front surface of the cuff 4, see in particular Figure 5. A stop 26 projects into the hook mouth 23, the function of which will be described later. A control flank 27 extends below the stop 26, which, when the locking member A is closed, is parallel to the... Direction of displacement of the actuating slide 18 and is located on the side of the stud 17 - pivot pin - facing the cuff 4. At the height of the stud 17, the control flank 27 merges into an adjacent ramp 28, which lies in the movement range of a control cam 29 of the actuating slide 18. In the open position of the lock 1, the control cam 29 is located directly below the stop 26. Furthermore, the control cam 29 rests on the control flank 27. .

A recess 30 with an open edge and a run-out slope 31 extends from the edge 25" of the hook latch 22. When the hook latch 22 is closed back, a locking projection 32 attached to the actuating slide 18 extends from the upper end of the recess 30. This interacts with a lower corner edge 33 of the hook latch 22. It can be seen from Figures 5' and 6 that when the hook latch 22 is closed back, the locking projection 32 is covered so that no additional installation space needs to be created for it behind the hook latch 22. . ■ · ■

VGN: 258 024 A 20 989 Dr.G./We. 7.1.19913

In order for the actuating slide 18 to be able to be moved completely into its lower end position, it forms an entry slot 34 which is open at the edge and which is aligned with the stud 17 and runs in the direction of movement of the actuating slide 18 '.

Above the locking member A, another locking member B is provided. The latter is designed as a linearly extending mandrel 35. The direction of movement of the mandrel is perpendicular to the direction of displacement of the actuating slide. In the embodiment, the mandrel 35 is equipped with bevels 37 on both sides of its locking head 36. Each bevel 37 is made up of two obtuse-angled "beveled surfaces F and F', such that the beveled surface F encloses a larger angle to the direction of displacement of the locking member B.

On the inside of the lock, the locking member B has a locking tail 38 that is made of the same material. This supports a pin 39 that passes through a control slot S of the actuating slide 18 and enters a guide slot 40 of the lock base 12 that runs vertically to the cuff 4. The control slot S has a central slot section 41 that rises diagonally in the direction of the cuff 4, to which an upper slot section 42 adjacent to the cuff 4 is connected: This is aligned parallel to the direction of movement of the actuating slide. Then, the diagonal slot section 41 is followed downwards by a slot section 43 arranged parallel to the cuff 4. If the pin 3.9 is in the slot sections 42, 43, a displacement of the locking member B is blocked. . ,

VQN: 258 024 A 20 989\ Dr.G. /We. 7.-I-.-1998

The locking elements A, B work together with a locking plate 44 on the frame side, indicated by dash-dotted lines. This forms an entry opening 45 for the locking element A and an entry opening 46 for the locking element B. ■·■■',. ; ., ; ·

The following effect occurs:

If the drive rod lock 2 is to be moved from its open position according to Figure 1 into the closed position

., this requires an actuation of the locking cylinder 8 using the associated key 9. In this case, the bolt 6 is pre-locked, as can be seen from Figures 3 and 4. At the same time, the drive rods 10, 11 are also displaced. The drive rod 10 takes the actuating slide 18 with it in a downward direction. The control cam 21 runs along the control flank 27 of the locking member A, but does not yet cause the locking member A to swing out. In contrast,

, the control slot S causes the locking element B, which forms the bevel 37, to be pre-closed via its diagonally rising slot section 41. This plunges into the entry opening 46 of the strike plate 44 and causes a door equipped with the drive rod lock 2 to be pulled. The advance movement of the locking element B is completed when the pin 39 is on the outlet side of the slot section 41 and is aligned with the slot section 42. During continued closing operation, the control cam 29 hits the ramp 28 of the hook bolt 22 and causes the hook bolt to pivot into the position shown in Figures 4 and 7. During the pivoting, the pin 39 plunges into the slot section 42. Accordingly, the path that serves to secure the locking pin 35 against being pushed back is used to pivot the hook bolt A. In the fully forward pivoted position

VGN: 258-024 A 20 989 Dr.G./We. 7.1.1998 . . '

In this position, its stop 26 comes into contact with the rear surface of the cuff 4, see Figure 7. Furthermore, the downward movement of the actuating slide 18 causes its locking projection 32 to reach the level of the corner edge 33 of the hook bolt 22, so that this cannot be swung back. Since the door is pulled in by the bolt member B during this previously described closing process, the bolt member A, designed as a hook bolt 22, can enter the corresponding entry opening 45 of the strike plate 4 without hindrance under

&bull; ^l , ■ " - '■" ■ . · ·'■',■"■■■■. Creating the composite engagement between the strike plate 44.

and locking link A.

To open the drive rod lock 2, an opposite closing rotation is required. This results in an upward displacement of the drive rod 10 and thus of the operating slide 18. In the initial phase of the displacement of the operating slide 18, the control cam 29 acts on the control flank 27 of the locking member A and pivots this into the open position. This is possible because at the same time as the upward displacement of the operating slide 18, the locking projection 32 has moved away from the corner frame 33'. As the displacement of the operating slide 18 continues, the locking member B is then retracted ^via the control slot S, so that after the opening and closing has been fully carried out, the pin 39 extends into the lower slot section 43 and thus secures the locking member B' in its retracted end position.
