Installation on an insert mounted on telescopic rails in a housing

The invention relates to a device on a slide- in unit mounted on telescopic rails in a housing for locking in a specific / in particular fully extended position.

around drawers of great depth / those in housings, cupboards or racks are arranged / can be fully extended /

IS is known to use so-called telescopic rails, which consist of a fixed part in the housing and a or two movably interlocking parts / in or on soft the drawer is suspended or stored.

In a similar way, electrical devices or electronic assemblies are installed in switch cabinets built up.

έ5 To on or with the in the drawers or slots To be able to handle objects undisturbed, it is necessary / to lock the drawers on the telescopic rails in a certain position, especially when the telescopic rails are fully extended.

There is therefore the task of creating a device with which a locking can be made, which are constructed in the simplest possible way and versatile, especially with standard telescopic rails, is usable.

The object is achieved with a device / which has the features of claim 1.

By automatically pivoting the bolt from its working position to its rest position or vice versa, the slide-in or the drawer pushed in to the rear wall of the housing “It will be a better use of space Reached in the housing or in the viewing position *

In a preferred embodiment, it is pivotable Bolt mounted on a plate-like molded part, which is at any point on a movable part of the Slide on the telescopic rail and fix it there. Due to its symmetrical training to the longitudinal center line, it can this molding for both sides of a pair of telescopic rails be used. On the Teies-kopsehien is only to make a recess, preferably a hole, in which a latch located on the molded part can resiliently engage.

To explain the invention, exemplary embodiments and functional sequences are shown in FIGS. 1 to 3 described below.

Figure 1 shows a perspective view of the bolt, Figure 2 the molded part with bolt in the working position, Figure 3 a to d the sequence of movements when inserting the Telescopic rail.

The bolt 1 shown in Figure 1 is a one-piece structure with an approximately trapezoidal outline made of light, elastic plastic.

At its narrow end, a transverse bore 2 is made for receiving an axle. The recess 3 allows it to be plugged on or clamping a Seger ring or the like onto the axle in order to achieve an axial displacement of the bolt impede.

A recess 4, which is to be widened towards its broad end, is delimited by two legs 5 and 6 / the inner surfaces of which are designed as slideways 7 for a turning pin described in more detail in FIG. The front end of the leg 6 is designed as a sharp locking edge 8 running parallel to the pivot axis a - a. ″.

-2. shows the locking device on a

Telescopic rail 9 mounted / on the end of a movable part 9 * of this telescopic rail. For this purpose, a plate-like molded part 10 with two rail-like projections 11 running symmetrically to the longitudinal center line is pushed onto the end of the part 9 'of the telescopic rail 9 / the rails 11 encompass the longitudinal edges of the part 9 ″. The molded part 10 is thus fixed in the transverse direction « A locking lug 12 / which snaps into a recess / for example "a bore 13 / in part 9" of the telescopic rail 9 is used for fixing in the longitudinal direction plate-shaped molded part 10 is arranged.

From the figure it can be seen that the molded part 10 is synurtetrical to its longitudinal center line is formed and on its wider, the end of the movable part 9 " the end facing the telescopic rail is provided with two axle bolts 14 arranged perpendicular to the plane of the plate which the bolt 1 can be attached, in such a way that, depending on whether the right or left rail of a pair of telescopic rails is equipped or both, in each case the above-Üegende axle pin 14 is used.

The bolt 1 is shown here in its working position. Its lower leg 6 rests on part of the telescopic rail 9. This is fully extended to an unwanted one To prevent it from being pushed in, the bolt 1 can move with it

a locking edge 8 on a preferably lying in the front plane of the housing or the cabinet shoulder 15, here z. B. against the front edge of the fixed part of the telescopic rail 9.
5

To solve the locking, the bolt 1 must be lifted by hand and the Einähub pushed in until the handle 6 dee bolt 1 on the upper length edge 16 of the fixed part 9 ″ of the telescopic rail 9 or a similar or appropriately designed cream inside of the housing slides.

Figure.,! shows the turning process when inserting the telescopic rail in four phases.

In order to bring the bolt from its working position shown in FIG. 2 and also in FIG. 3a into a rest division, a turning pin 17 is generally arranged inside the housing near the rear end position of the insert, which enters the recess 4 of the bar 1 and on the slide 7 of the leg 5 slidingly rotates the bolt 1 by about 180 ° about the axle pin 14, as shown in FIGS. 3b and 3c.

The telescopic rail and the / slide-in module stored in it can so fully inserted up to the rear wall b - b 'of the housing (Figure 3d), so that the clear space in the housing can be fully utilized.

The diverging course of the legs 5, 6 delimiting the recess leaves a relatively large structural dimension Room for maneuver when attaching the pivot pin 17 to.

If the pair of telescopic rails is pulled out again, the sequence of movements and the interaction between Turning pin 17 and bolt 1 in reverse order. The bolt 1 is from its rest position again
