Description

The invention relates to a lock, in particular for a sliding door, according to the preamble of claim 1.

Basically, such locks are known in practice in different configurations. However, these conventional locks are usually not suitable for installation in sliding doors, because the profiles or fillings of the sliding doors have only very small dimensions or material thicknesses. Nevertheless, there is a need for locking sliding doors, especially when they are part of a space dividing element.

The DE 43 00 810 A1 relates to a bolt lock for a glass door, the housing is mounted on both sides of a door leaf.

A generic lock usually has a lock case. This takes on the actual lock mechanism and is in the final assembled state of a lock cylinder, for example, in the form of a profile cylinder, through which an actuation of the lock mechanism can be made. For receiving a lock case through the door leaf of a door in the door leaf usually accessible via the narrow side of the door panel recess in the form of a pocket is provided which receives the lock case in the final assembled state. The access opening to the bag is closed in the final assembled state by a cuff located on the lock case. To secure the position of the lock case or the forend with it arranged lock case relative to the door leaf is usually provided a screw of the forend with the door leaf.

On the door leaf main sides for shielding, for example, the end portions of the profile cylinder door shields are usually arranged, on both sides of the door leaf. To secure the position, the door shields can be screwed to the door leaf and / or the lock case. To cover the door shields covers in the form of veneers may be provided, which are pushed, for example, on the respective associated door shields, clipped or otherwise attached to the respective door plate.

Although locks of the type described above have proven themselves in everyday practice, there is room for improvement, especially with regard to improved security against manipulation. It is therefore an object of the invention to propose a comparison with the prior art improved lock, which provides improved security against manipulation over prior art locks.

To solve this problem, a lock of the aforementioned type is proposed with the invention, which is characterized by a stulpseitig of the lock box operable and connecting the door plate with the lock case connecting device.

The connecting device can only be operated with the door open, that is unlocked lock. Access to the connecting device via one of the two large areas of a door leaf, however, is not readily possible in an advantageous manner.

Further advantageous embodiments and features of the drawing and the description of the rest can be seen.

Fig. 1 shows a sliding door assembly in a side view. There are two wings 10, 12 of a sliding door 14 shown, which are displaceable in a common, identical vertical plane. The wings 10, 12 of the sliding door 14 each have a conventional frame, of which only the vertical frame profiles 16, 18 are shown in the present case, and a filling 20. The filling may be a panel-like element made of a wood material, plastic , Metal, glass or the like. Furthermore, fillings 20 are conceivable, which consist of a combination of the aforementioned materials.

The two wings 10, 12 of the sliding door 14 are in the in Fig. 1 and 2 shown closed position by a lock 22 lockable. The lock 22 is characterized by a particularly flat design. In addition, the lock 22 can be adapted to different fillings 20 with different thickness.

The lock 22 consists of a lock case 24 and a strike plate 26, which are arranged in the region of the frame profiles 16, 18 on both wings 10, 12, so that the wings 10, 12 can be locked by engaging a bolt 28 of the lock case 24 with the strike plate 26 are. The latch 28 of the lock case 24 is actuated by a lockable in the lock case 24 lock cylinder 30, in particular a profile cylinder. For this purpose, the lock cylinder 30 has a rotatably actuable driver 32 which can be actuated in a known manner by rotation of a key 34 which can be inserted into the lock cylinder 30.

A special feature of the lock cylinder 30 is that it has a particularly short design, but otherwise largely corresponds to a standard cylinder. Fig. 2 shows that the lock cylinder 30 has substantially the same length as the corresponding depth of the frame profiles 16, 18. The lock cylinder 30 is stationary thus substantially not opposite outer levels formed by the frame profiles 16, 18.

Another special feature of the lock cylinder 30 is that it can be closed from both sides despite the short length. In this way, the sliding door 14 can be used for example in a room divider, and be closable from both sides.

For receiving the lock cylinder 30, the lock case 24 has a recess 36 into which the lock cylinder 30 can be inserted. A special feature, however, is that the recess 36 has larger dimensions than usual. Another special feature is that the width of the lock box 24 corresponds to the width of the driver 32 of the lock cylinder 30, i. the lateral flanks of the driver 32 extend in the plane of the side surfaces of the lock case 24. This has the consequence that the driver 32 is completely rotatable within the recess 36 and does not protrude beyond the recess 36 in the lock case 24.

For storage of the lock cylinder 30, two door plates 38, 40 are provided on both sides of the lock case 24. The door panels 38, 40 are placed against the sides of the lock case 24 and each have a recess 42, whose shape and dimensions correspond to the lock cylinder 32. In this way, the lock cylinder 30 is mounted on the door shields 38, 40, which in turn are secured to the lock case 24, for example by screws 68 which are connected by corresponding holes 46 in the lock box 24 and the door shields 38, 40 through threaded bushes 44.

To the outside, the door panels 38, 40 are covered by panels 48, 50. The panels 48, 50 may be subsequently arranged on the frame profiles 16, 18 and enclose the support profiles 38, 40 laterally as well as on the exposed edges. The attachment of the panels 48, 50 on the door panels 38, 40 is effected by engagement of molded on the top and the underside of the panels 48, 50 projections 52 in a corresponding recess 54 on the top of the door panels 38, 40 and by screwing in the area Bottom of the panels 48, 50 and the door panels 38, 40. Fig. 7 shows a screw 56 for this purpose.

Another special feature relates to a connecting device for the lock 22. The lock cylinder 30 is in a conventional manner with a lock cylinder screw 58th attached to the lock case 24. The lock cylinder screw 58 is thereby screwed from the end face of the wing 12 so stulpseitig in the lock case 24. In the region of the screw channel of the lock cylinder screw 58 retaining bolts 60 are arranged, which extend at an angle to the screw and this at least partially intersect. The retaining bolts 60 are inserted in mutually parallel planes from both sides through openings 62 in the door shields 38, 40 and the lock case 24 and have in the region of the intersection with the screw channel a groove 64 or groove into which the lock cylinder screw 58 preferably engages positively , In this way, the retaining bolts 60 are secured by the screwed lock cylinder screw 58 against pulling out. The connecting device is formed by the lock cylinder screw 58 as a locking screw and the retaining bolts 60.

Furthermore, the retaining bolts 60 on the outside a thickening 66 which has larger dimensions than the corresponding openings 62 in the door plate 38, 40. In this way, a removal of the door shields 38, 40 of the retaining bolt 60 without first removing the lock cylinder screw 58 and the retaining bolts 60 prevented.

The arrangement described above leads to a security of the closed sliding door 14. After closing the lock 22, the lock cylinder 30 can not be removed because the lock cylinder screw 58 is not accessible. Although the panels 48, 50 can be removed from the door panels 38, 40, but a degradation of the door panels 38, 40 from the lock box 24 is not possible because they are secured by the engagement of the lock cylinder screw 58 with the retaining bolts 60. An opening of the wings 10, 12 of the sliding door 14 is thus not destructive possible.

Out Fig. 4 It can be seen that both the apertures 48, 50 and the retaining bolts 60 are offered in different dimensions to adapt to the width of the frame profiles 16, 18 on the one hand and the thickness of the filling 20 on the other. In the present embodiment, a door plate 38, 40 is arranged on both sides of the lock case 24 respectively. However, it is understood that the use of only one-sided door plate 38, 40 is conceivable.

Furthermore, the use of the lock 22 is not limited to sliding doors but also in other doors or windows conceivable. <B> LIST OF REFERENCES: </ b> 10 wing 58 Lock cylinder screw 12 wing 60 retaining bolt 14 Sliding 62 opening 16 frame profile 64 Fillet or groove 18 frame profile 66 thickening 20 filling 68 screw 22 lock 24 lock case 26 striking plate 28 bars 30 lock cylinder 32 takeaway 34 key 36 recess 38 nameplate 40 nameplate 42 recess 44 threaded bushing 46 drilling 48 cover 50 cover 52 head Start 54 deepening 56 screw
