Description

The invention relates to a locking pin for a window or door lock fitting with a bolt and a sleeve rotatably mounted on the bolt, wherein the sleeve relative to the bolt in at least one position provided by means of a bolt on the Annular groove and engaging in the annular groove locking element can be fixed.

Such a locking pin is for example from the DE 2 903 837 C3 known. In the known locking pin, the bolt has an annular groove and the sleeve rotatably disposed thereon on its inside two annular grooves. In the intermediate space between two opposing annular grooves, the locking element is arranged. A disadvantage of the known locking pin, that in each case at least one annular groove must be introduced both in the bolt and in the sleeve. On the other hand, the production of the locking pin designed as difficult, since the locking element between sleeve and bolt must be brought.

Object of the present invention is in contrast to provide a locking pin, which is cheaper and easier to produce.

This object is achieved by a locking pin of the type mentioned, wherein the sleeve has at one end an axial stop for the locking element, wherein the locking element is fixed to the sleeve. Preferably, the axial stop on the drive rod side end of the sleeve, ie at the end of the sleeve, which points in the direction of the drive rod when the lock pin is mounted, is provided. The axial stop preferably has a stop surface, which is aligned substantially perpendicular to the longitudinal axis of the sleeve. The axial stop may be designed annular and formed by a step of the sleeve. The latching element is preferably arranged radially resiliently with at least one section. This makes it possible, though a plurality of annular grooves are provided on the bolt to gradually adjust the sleeve on the bolt.

Characterized in that the axial stop is arranged at one end of the sleeve, the inside of the sleeve does not have to be machined to introduce there annular grooves. In particular, the inside of the sleeve may be substantially smooth, in particular free of ring grooves. For the assembly or production of the locking pin of the bolt can be inserted into the sleeve and then the locking element can be applied to the axial stop. Then it can be attached to the sleeve. Alternatively, first the locking element can be attached to the sleeve and then the bolt can be inserted. In both cases, the assembly is easier than in known locking pin.

According to one embodiment, it can be provided that the stop is hammered into the sleeve on the front side. This has the advantage that the sleeve does not have to be machined. The stop can be made particularly easy in this way. In particular, a step on the sleeve can thereby be produced in a particularly simple manner. The stopper is preferably arranged inside in the sleeve.

The latching element can be attached to the sleeve in a form-fitting and / or cohesive manner. For example, the locking element can be glued to the sleeve, soldered or welded.

However, an embodiment in which a particular frontal section of the

Sleeve is recast. As a result, the latching element can be attached to the sleeve particularly easily and quickly. It may be sufficient if the sleeve is re-embossed only at one point and the latching element partially engages, in particular holds in contact with the axial stop.

In one embodiment of the invention can be provided that the stop is circular and the locking element is not circular, in particular oval, square or U-shaped. This ensures that the latching element can deflect radially at least at one point in order to allow an axial adjustment of the sleeve with respect to the bolt.

According to a variant of the invention it can be provided that the stop is rectilinear. In this case, a particularly simple locking element, in particular in the form of a wire, can be used. The stop is preferably arranged so that the spring element abutting thereon extends with a portion through the interior of the sleeve.

The locking element can be arranged rotationally fixed to the sleeve.

According to a particularly preferred embodiment of the locking pin according to the invention can be provided that the bolt has a plurality of axially spaced annular grooves. This means that the sleeve can be fixed axially in different positions relative to the bolt. The sleeve can therefore be moved gradually axially relative to the bolt. In particular, the sleeve can be manually axially be adjusted with respect to the bolt. The locking element slides over the shoulder of an annular groove, or the material web between two adjacent annular grooves, in the next annular groove. There, the sleeve, if no external forces are applied, in turn fixed axially via the locking element on the bolt.

It can be provided that the sleeve is fixed in a predetermined position and the correct position of the sleeve is adjusted with respect to the bolt manually by a fitter during assembly of the locking pin on a window or a door. Furthermore, it can be provided that, in a first use of the locking pin in cooperation with a closing piece, the axial position of the sleeve with respect to the bolt is adjusted automatically. Accordingly, when the sleeve of the locking pin first enters a locking piece, the sleeve can be pulled out depending on the position of the closing piece or be displaced in the direction of the drive rod of the espagnolette fitting. For this purpose, it is advantageous if at least three annular grooves are provided on the bolt and in a starting position, the locking element is arranged in the middle annular groove.

Furthermore, it can be provided that the sleeve is formed mushroom-like. As a result, the sleeve can engage behind a section of a closing piece. This embodiment of the sleeve is particularly advantageous when an automatic axial adjustment of the sleeve is to be made on first use.

The bolt may have two eccentrically arranged bolt portions, wherein the sleeve on the upper

Bolt portion is arranged and the lower bolt portion is rotatably arranged in a slider or a drive rod. This makes it possible to adjust the contact pressure of the movable sash to the seals. Furthermore, tolerances from the manufacture of frames and / or wings as well as variations (e.g., "settling") due to prolonged use and mechanical stress can be compensated.

In a preferred embodiment of the invention can be provided that the bolt have a collar and the sleeve has a lifting of the sleeve from the bolt preventing second axial stop.

Particular advantages arise when a combined tool engagement is provided for at least two different tools on the bolt. For example, a hexagon socket and a Phillips can be provided as a combined tool engagement. Firstly, no special tool is necessary for adjusting the bolt. On the other hand, it is assumed that a fitter has either an Allen key or Phillips screwdriver quickly to hand to make an adjustment of the locking pin can. The setting of the locking pin can be done faster and more reliable. Other tool engagements or tool engagement combinations are also conceivable, e.g. TORX, Slot, Pozi, Philipps, Robertson. In this case, the tool engagement for different countries can be adapted to there common tools.

In the context of the invention also falls a method for producing a locking pin according to the invention, in which an axial stop is taken at one end of a sleeve, a bolt with an annular groove is inserted into the sleeve and a locking element is fixed to the stop before or after the insertion of the bolt. The production of the locking pin is made particularly simple by this method. In addition, the process is easy to automate.

According to a preferred variant of the method can be provided that the locking element is fixed by deformation, in particular stamping, a part of the sleeve at the stop. As a result, no additional fastening means for fastening the locking element to the sleeve are necessary.

It is particularly advantageous if the sleeve and the bolt are produced without machining, in particular exclusively with cold hammering. As a result, the production of the locking pin is particularly cost-effective and less expensive.

Further features and advantages of the invention will become apparent from the following description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The individual features can be realized individually for themselves or for several in any combination in a variant of the invention.

FIG. 1 shows a sectional view through a locking pin 1. The locking pin 1 comprises a bolt 2 and a sleeve 3 rotatably mounted thereon. The bolt 2 has a slider 4 projecting through a lower bolt portion 5 and an upper pin portion 6. The bolt portion 5 can be fixed to a drive rod. In the exemplary embodiment, the upper pin portion 6, which has a larger diameter than the lower pin portion 5, two annular grooves 7, 8. In one of the annular grooves 7, 8 comes to a fixed to the sleeve 3 locking element 9 to lie. As a result, the sleeve 3 is fixed axially with respect to the bolt 2. The locking element 9 is designed as a spring element and abuts against an axial stop 10 of the sleeve 3. The axial stop 10 is formed by a step in the wall of the sleeve 3. The axial stop 10 has a Stop surface, which is aligned perpendicular to the axis of the sleeve 3. The stop 10 can be taken from the front side of the sleeve 3 ago. It is located on the drive rod end 11 of the sleeve. 3

For fixing the locking element 9 to the sleeve 3, the sleeve part 12 is at least locally umgeprägt. As a result, the latching element 9 is fastened in a form-fitting manner to the sleeve 3. The locking element 9 can dodge radially with a part, so that it can be moved across the material web 13 away in the adjacent annular groove 8.

The bolt 2 has a collar 14 which engages over a second axial stop 15 of the sleeve 3. As a result, a lifting of the sleeve 3 can be prevented from the bolt 2, which is an anti-burglar.

It can be seen that the sleeve 3 is mushroom-shaped, in particular has an edge 16. With the edge 16, the sleeve 3 can cooperate with an undercut of a closing piece. When first locking by means of the locking pin 1, the sleeve 3 can be pulled through the closing piece up, so that the correct position relative to the pin 2 results. On the bolt 2, a plurality of annular grooves 7, 8 may be provided, so that the sleeve 3 can be set stepwise in different axial positions with respect to the bolt 2. In an odd number of annular grooves 7, 8, the locking element 9 is preferably in the delivery or mounting state in the middle annular groove 7, 8th

The bolt sections 5, 6 are arranged eccentrically to one another. When a tool is intervened in the tool engagement 17, the bolt 2 with respect to the slider 4 and optionally one Driving rod to be twisted, and so to reduce play between the locking pin 1 and a striker. The slider 4 may be slidably disposed in a cuff rail of a drive rod fitting, not shown here.

In the FIG. 2 it can be seen that the bolt sections 5, 6 are arranged eccentrically to each other. At the bolt portion 6, the annular grooves 7, 8 are formed. It can be seen that in the exemplary embodiment, the locking element 9 is formed as an oval spring element. With his legs 20, 21 it engages positively in one of the annular grooves 7, 8 a. The legs 20, 21 can be positively and / or materially secured to the sleeve 3 not shown here. This results in that the locking element 9 can be positively held both on the pin 2 and on the sleeve 3.

The FIG. 3 shows a view from below of the lock pin 1 without slider 4. The sleeve 3, for example, at the points 25, 26 deformed or be embossed, to secure the locking element 9 in the axial direction of the bolt 2. As a result, the locking element 9 then, after the Forming, held positively on the sleeve 3. Despite the embossing, the locking element 9 can yield radially when the sleeve 3 is displaced axially relative to the bolt 2 by increased force. It can be seen that the locking element 9 is interrupted at the point 27. This allows the locking element 9 to avoid radially against a restoring force.

The FIG. 4 shows a plan view of the lock pin 1. To see here is the tool engagement 17, which is designed as a hexagon socket. By a marker 28, the rotational position of the bolt 2 with respect to the slider 4 and a drive rod is displayed.

The FIG. 5 shows an alternative embodiment of a locking pin 30. In this embodiment, the sleeve 3 on the front side recesses, whereby the axial stops 31 - 33 are formed. The stops 31 - 33 have been produced by frontal impact of the sleeve 3. The stops 31, 32 are aligned with each other, so that a wire-shaped locking element 35 can be inserted. A portion of the latching element 35 is arranged in the interior 37 of the sleeve 3 in such a way that this section also comes to lie in one of the annular grooves 7, 8. Thus, the sleeve 3 can be fixed axially with respect to the bolt 2. The latching element 35 can deflect radially in order to allow an axial stepwise displacement of the sleeve 3 with respect to the bolt 2. The latching element 35 is attached to the sleeve 3 by gluing, welding to the sleeve 3 or at least partially embossing the sleeve, in particular the front edge 38 of the sleeve 3. If an embossing, the locking element 35 is positively secured to the sleeve 3. The abutment surfaces of the stops 31 - 33 are aligned perpendicular to the longitudinal axis of the sleeve 3.
