Description

The invention relates to a lock, in particular Main lock or additional deadbolt lock, with one Lock housing and a bolt bolt with bolt foot and Bolt body, the bolt foot in the lock housing slidably guided and the bolt body from the The lock housing can be pushed out.

Such a lock is e.g. from DE 200 18 104 U1 known. The content of this document is hereby incorporated into the present description introduced. This lock points a lock housing in which a bolt bolt is slidably mounted and guided and the bolt body the bolt bolt can be pushed out of the lock housing. The invention has for its object a lock to provide a higher security against Offers manipulation and vandalism.

This object is achieved with a lock at the outset that the Bolt bolt an insert plate, in particular made of steel, has, which is encapsulated by a die-cast material.

In the lock according to the invention, the bolt bolt is not Made from one material, but consists of two different materials, namely one Steel insert plate and a steel insert plate enveloping die casting material. This has the essential Advantage that the external properties of the bolt bolt in terms of weather resistance, appearance and the coefficients of friction are comparable to those of one Bolt bolt according to the prior art, however burglar resistance due to the steel insert is significantly increased since a deformation of the Bolt bolt or severing the bolt bolt, e.g. sawing is excluded. The steel insert gives the bolt bolt for a raised Burglar resistance required rigidity and strength.

In a further training it is provided that the Steel insert plate in the bar foot and in the Bolt body extends. This will prevent the Bolt bolt z. B. at the transition from the transom to Bolt body is severed. It also increases such a continuous steel insert, the rigidity of the Bolt lock.

According to the invention, the steel insert plate has at least a breakthrough in which the die casting material anchored. In addition to the surface adhesion or connection of the both materials over their surfaces will also be one positive connection achieved by that Die casting material penetrates into the steel insert plate or this penetrates, causing the on both sides of the Steel insert plate located Die-cast material trays are connected to each other.

According to the invention, the die casting material is a zinc-copper alloy (ZnAl ₄ Cu ₁ ). Such an alloy has the required resistance to weather influences as well as the necessary abrasion resistance and good sliding properties. In a further development of the invention, the steel insert plate is hardened so that it cannot be deformed or cut with conventional burglary tools.

To the bolt latch in a simple manner Activate lock housing, i.e. to be able to move a guide pin from the plane of the steel insert plate herausgepragt. Before hardening the steel insert these with the breakthroughs and it becomes the Guide pin by means of a stamping process from the plane the plate, on which the Control element, e.g. a connecting rod connecting slide attacks for the bolt bolt.

In a further development it is provided that the guide pin the die-casting material surrounding the steel insert towers over or emerges from it. This means the control is right on steel attacks existing pilot pin, so that relatively high Transfer forces from the control to the bolt latch can be made without the bolt bolt material up is stressed to its limit.

According to the invention it is provided that the bolt body in Exclusion direction seen two side and one middle region, which is substantially the same Have width. The middle area has a over the outer surface of the side areas protruding guide surface. Such a trained one Bolt body has a relatively large width, which makes it increased resistance to deformation or Severing offers, whereas the plant of the Bolt bolt on the striking plate only over the Guide surface takes place, which is only in one Area, e.g. in the middle area, this bolt body is located, which significantly reduces the frictional forces become. Another variant provides that instead of the middle area another area with local limited guide surfaces is provided, whereby comparable effects can be achieved.

To further reduce the frictional forces, one is preferred embodiment provided that the width the guide surface from the free front edge of the Bolt body decreases in the direction of the bolt foot. This means that as the Bolt bolt, in which the bolt body in the striking plate that occurs at the bolt opening of the striking plate contact surface of the bolt body is reduced, which also reduces the frictional forces.

In a further training it is provided that the Guide surface in the form of a partial circle in cross section is. On the one hand, the one deviating from one level Form prevents opening with a demolition tool simple way between the previous ones Bolt bolt and the bolt opening of the striking plate can be intervened, on the other hand a centering the bolt bolt in the bolt opening of the striking plate causes.

Finally, it is provided that the guide surface in Seen in the longitudinal direction is wedge-shaped or conical. This has the advantage that as the prefix increases Tightening or pulling up the door or window sash, in which the lock is embedded in, on the frame rebate he follows. This will make the wing feel full guaranteed.

Further advantages, features and details of the invention result from the following description, in which with reference to the drawing a particular preferred embodiment described in detail is. It can be shown in the drawing as well mentioned in the description and in the claims Features individually for themselves or in any Combination be essential to the invention.

The general structure of the lock with lock housing, Espagnolette connecting slide as well as guides for one Bolt bolt is detailed in DE 200 18 104 U1 shown and described and it is full on this publication is referred to. In Figure 1 is only the bolt bolt designated 10 in total shown, the design of which is described in more detail below is described.

The bolt bolt 10 has a bolt base 12 and one Bolt body 14 which are integrally connected to one another. The bar base 12 has a slightly larger width than the bolt body 14, whereas the bolt body 14 is longer than the bar base 12. With Dashed line 16 is a steel insert plate 18 indicated in detail in FIGS. 4 to 6 is shown and described.

The steel insert plate 18 is at a distance from the Outer edges of the bolt foot 12 and of the bolt body 14, which means that this is completely from one Die casting material 20 is cast. However, this relates not on a guide pin 22 which, as shown in FIG clearly recognizable, the die casting material 20 penetrates and clearly surpassed this.

As can be seen from FIG. 6, the guide pin 22 is made of the level of the steel insert plate 18 by means of a Embossing process shaped in the direction of arrow 24, see above that it sticks out sideways. In this process, the Steel insert plate 18 and openings 26 and 28th molded in when casting the steel insert plate 18th Pick up die casting material 20. In this way, one intimate connection of the die casting material 20 with the Steel insert plate 18 reached. The guide pin 22 engages in one (not shown) as a control element trained connecting rod connecting slide, over which of the bolt latch 10 from the lock housing pushed out or retracted into it.

When pushing the bolt bolt 10 out of the lock housing the bolt body 14 comes out of the lock housing and engages in a bolt opening, not shown Strike plate. The is particularly suitable for this wedge-shaped structure of the bolt body 14, which is shown in FIG is clearly recognizable.

The bolt body 14 is, as can be seen from Figure 1, in two lateral areas 30 and 32 and a central area 34 divided, the central region 34 one over the Has outer surface 36 projecting guide surface 38, which can be clearly seen from Figure 2. The respective Widths of the areas 30 to 34 are approximately the same size. The guide surface 38 tapers, starting from the free front edge 40 of the bolt body 14 in the direction of Bar foot 12, i.e. its width 42 decreases. in the Cross-section, the guide surface 38 is part-circular configured, which is clear from Figure 3.

A lock with such a bolt 10 offers a much greater resistance to burglary since One of the bolt bolts 10 has a greater width than conventional bolts and also the steel insert plate 18 a deformation or destruction of the bolt bolt 10 prevented. The guide surface 38 ensures despite large width of the bolt bolt 10 a smooth Prelude, since the contact surface of the bolt 10, the is defined by the guide surface 38 in size is limited, and thereby the frictional forces are minimal being held. The above also allows Guide pin 22 an indirect introduction of the actuating forces on the steel insert plate 18 and thus an optimal one Distribution within the bolt bolt 10.
