Description

The invention relates to a Treibenstangenverschluss with the features of the preamble of claim 1.

From the EP-A-0 578 004 is an espagnolette with a remote from the main lock box additional bolt lock with additional bolt known. The additional bolt is housed in a housing consisting of at least two parts and pivotally mounted on a housing-fixed axis of rotation. The pivoting takes place by means of a floating bolt which is entrained by the two espagnolette slides on actuation of the drive rod. Depending on the locking position, arms of different lengths act between the axis of rotation of the bolt and the floating bolt. A backup against unauthorized pivoting back of the pivoted bolt is created by the position of the slots in the pivot bolt and in the housing. The swung back latch is secured against unintentional swinging by a compression spring.

From the EP-A-0 634 552 is also an espagnolette with a remote from the main lock box additional bolt lock with additional bolt known. The additional bolt is also housed in a housing consisting of at least two parts and pivotally mounted on the housing with a rotation axis. This additional bolt has a lateral recess into which engages a mounted on a drive rod connecting slide driver and the pivot bolt in a drive rod actuation off or can swing. When swinging act differently long lever arms between bolt pivot axis and driver. Due to the shape of the recess and the driver of the bolt is secured in both the pivoted out and in the retracted position.

From the DE-A-34 27 712 is also an espagnolette lock with an additional bolt lock with additional bolt known, but which has a constant lever arm between the axis of rotation and control pin. As a result, however, an unfavorable torque curve is achieved. The bolt is also not secured in both end positions. However, he has a reverse lock.

From the EP-A-0 891 465 a hook bolt additional lock has become known, which, however, is provided with an unfavorable, decreasing lever length profile when swinging the bolt. Furthermore, two drive rod connection slide are provided, which act on a drive axle. In the one-piece housing, the components are inserted through the stülpseitige opening.

Overall, it can be stated that the additional bolt locks according to the prior art are either complex or do not meet the current requirements for ease of use or security against burglary.

From the WO-A-97 38 195 and from the EP-A-1 020 597 Espagnolette locks are known with a main lock and at least one additional lock. The additional lock has a pivot bolt and a slider over which the pivot bolt is driven. The slider is held and guided between the pivot bolt and the lock cover or lock bottom.

The invention is therefore based on the object to provide an additional bolt lock, wherein the leadership of the slider is independent of the pivot bolt.

This object is achieved with a drive rod lock, which has the features of claim 1.

The additional bolt lock according to the invention is constructed so that the components can also be inserted through the stülpseitige opening in the latch housing. Furthermore it only requires a single drive rod connecting slide, via which the pivot bolt is controlled. In this case, the provided on the espagnolette connecting cam engages in the control slot of the pivot bolt, pivots it out and forms with swiveled out swing latch a back-up against unauthorized pivoting back. The entire management and storage functions within the lock housing are taken over by the guide projections, which hold the one hand, the drive rod connecting slide in position and guide during its displacement movement and record between them the pivot bolt.

In a further development, it is provided that the latch housing is formed in one piece. This has the significant advantage that during assembly no riveting, compression, embossing or screwing is required to secure the parts of the latch housing together. Preferably, the latch housing is a diecast metal, in particular a zinc die-cast part, or an injection molded part. Metal die castings have a very high strength and are inexpensive to manufacture. Injection molding elements are very lightweight and can also have high strength due to a glass fiber reinforcement.

Preferably, the guide projections are designed as guide rails. These run in particular orthogonal to the direction of movement of the drive rod connection slide, ie a bolted housing produced as a die-cast or injection-molded part is easily demoldable. The guide rails are arranged so that they optimally guide the drive rod connecting slide in each shift position. In particular, the inside of the rear wall of the latch housing may be provided with a guide groove, in which the rear wall facing edge of the drive rod connecting slide is guided.

The guide projections or guide strips are provided on an inner side of the latch housing. Another advantage of the guide projections or guide strips is that they reduce the friction between the latch housing and the moving parts in the housing, namely the drive rod connection slide and the pivot bolt to a minimum due to the small contact surface.

In a further development of the invention it is provided that the pivot bolt is integrally formed with integrally formed pivot axis. This measure further reduces the number of components. In addition, such a pivot bolt with molded pivot axis is easy to manufacture.

With preference the pivot bolt is at a Embodiment provided with a projecting in the direction of the espagnolette slide slide-out prevention pin. This swivel prevention pin ensures that uncontrolled swiveling out of the swiveling bolt, eg when transporting the bolt, the door lock or the finished door, is prevented.

In a further development it is provided that the control slot of the pivot bolt extends substantially in the radial direction with respect to the pivot axis of the pivot bolt. This has the significant advantage that the ease of use is increased because the force curve increases above the angle of rotation of the pivot bar and therefore with increasing pivoting pivot bar higher forces to use a e.g. warped door can be applied.

In a particularly preferred embodiment, it is provided that the control slot has a pivoted in the bolt housing pivot bolt parallel to the direction of movement of the drive rod connecting slide extending first portion and a second section perpendicular thereto. In this case, there is an obliquely extending third section between the first and the second section. When swung Swingarm is the cam of the espagnolette in the first section. This means that the second section forms for the swung-out pivot bolt with its flanks a backup. The forces are transferred from this second section to the cam of the espagnolette connector and from there to the back of the latch housing.

In another embodiment, the pivot latch for receiving a pivot axis and / or Ausschwenk-preventing pin. These provided in an alternative embodiment recordings are usually provided in a steel bar in which correspondingly shaped pivot axes or pins are loosely inserted or pressed.

In one embodiment, it is provided that the drive rod connection slide is provided with a recess for a swivel lock provided Ausschwenk-prevention pin. This recess is provided with a shoulder, which engages in the pivoted position of the pivoting bolt Ausschwenk-preventing pin and prevents pivoting of the pivot bolt. Only by slight displacement of the drive rod connection slide, in which the shoulder of the pivoting range of the swivel-prevention pin is moved, the pivot bolt can be swung out.

A simple manufacture and reduction of components is further achieved in that the cam provided on the connecting rod slide cam is pronounced by deformation. Due to the particular cold deformation of the drive rod connection slide this area is additionally solidified.

In another embodiment, the cam may also be welded onto or inserted into the drive rod connection slide.

With preference, all components are plugged into each other, so that no screwing, riveting or stamping are required.

Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail. The features shown in the drawing and mentioned in the claims and in the description may each be essential to the invention individually or in any combination. In the drawing demonstrate:

FIG. 2

a section II-II according to Figure 1;

FIG. 3

a view in the direction of arrow III of Figure 1;

FIG. 4

FIG. 6

a side view of a pivot bolt; and

FIG. 7

a longitudinal section through the slide housing.

FIG. 1 shows a longitudinal section through an additional latch lock, which is denoted overall by 10. Such additional bolt lock 10 is part of a drive rod closure and is driven by a main lock by means of a drive rod. The drive rod, not shown, via corresponding couplings 12 with a drive rod connection slide 14 which is slidably mounted in the latch housing 16, coupled. This connecting rod connecting slide 14 rests with its rear edge on the inside of the rear wall 18 of the latch housing 16 and is supported on this. Advantageously, the rear wall 18 has a guide groove 20 for receiving the drive rod connection slide 14. The substantially U-shaped drive rod connecting slide 14 has between the two clutches 12 still a tab 22 on which a cam 24 is formed. Preferably, the cam 24 is pushed out of the plane of the drive rod connection slide 14 by embossing. Between the flap 22 and the adjacent coupling 12 there is a cutout 26 into which a shoulder 28 protrudes slightly. The shoulder 28 engages, as shown in Figure 1, a Ausschwenk-preventing pin 30 which is integrally formed on a pivot bolt 32.

This pivot bolt 32 has, as shown in Figure 6, a pivot axis 34 which is either integrally formed, inserted into a corresponding receptacle or pressed. This pivot axis 34, which protrudes from both sides of the pivot bolt 32, lies in U-shaped receptacles 36 of the latch housing 16. Further, the cam 24 engages in a control slot 38 which on a side surface of the Pivot bolt 32 is provided. This control slot 38 is designed in the manner of a blind hole and has a first portion 40, which extends substantially parallel to the direction of movement 42 of the drive rod connection slide 14. Adjoining this first section 40 is an obliquely extending third section 44, which opens into a first section 40 orthogonally oriented second section 46.

From Figure 1 it can be seen that the cam 24 can be moved by displacement of the drive rod connection slide 14 within the first portion 40 without the pivot bolt 32 is pivoted. If the cam 24 is moved to the left in the position shown in FIG. 1 by displacement of the drive rod connection slide 14, the shoulder 28 is likewise moved to the left and the swing-out prevention pin 30 comes free. By further displacement of the drive rod connecting slide 14 to the left of the cam 24 enters from the first portion 40 in the third portion 44 and the pivot bolt 32 is pivoted about the pivot axis 34 and emerges from the latch housing 16 gradually. In this case, the cam 24 moves further and further away from the pivot axis 34, whereby the torque for the swiveling out of the pivot bolt 32 is increased. For example, a distorted door can be over at the free end of the Pivoting bolt 32 provided oblique surfaces 48 are used.

If the pivot bolt 32 is completely pivoted out of the latch housing 16, which is shown in FIG. 4, then the cam 24 is located in the second section 46 of the control slot 38. If the pivot latch 32 is then pressed back against the pivot axis 34 in an anticlockwise direction, then this prevents it Groove flank of the second portion 46, a displacement of the cam 24 and thus forms a backup.

The swivel-preventing pin 30 is in the fully pivoted position of the pivot bolt 32 in the space provided for this recess 26 of the espagnolette 14th

In the figures 3 and 7 guide projections 50 can be seen, which are designed as guide rails 52. These guide rails 52 hold and guide the drive rod connecting slide 14 during its movement between the open and closed positions of the additional bolt lock 10. These guide rails 52 are integrally formed on the housing inner wall and serve to reinforce the bolt housing 16.

It can be clearly seen from the drawing that the additional bolt lock 10 is constructed from the latch housing 16, the drive rod connection slide 14 and the pivot latch 32. Both the espagnolette connector 14 and the pivot latch 32 are inserted through the stub side opening 54 (Figure 7) in the latch housing 16 and are held together in this by the guide rails 52. The simple structure and the small number of components allow an inexpensive production and cost-effective installation of the additional bolt lock 10th
