Description

Telescopic guides for furniture parts displaced in the body of the furniture {TELESCOPIC GUIDE FOR A FURNITURE PART ARRANGED DISPLACEABLY IN A FURNITURE CARCASS}

The present invention is a telescopic guide for a piece of furniture, such as a drawer, an extension, etc., positioned displaceably in a furniture body, the latch engagement with the furniture part via a latch member that can be fixed on the furniture part. Telescopic material having an extension rail which can be made, one or more guide rails which can be fixed on the furniture body, and preferably or possibly a central rail which increases the elongation length and is located between the guide rail and the extension rail It's about a guide.

Thus, a telescopic rail of this type is known from DE 890341 U1 or DE 20 2005 005 489 U1 according to this kind from essentially the same applicant.

Thus, joining a piece of furniture positioned displaceably within the furniture body to the extension rail so that the furniture part is fixed both in the axial direction and also in the transverse direction with respect to the axial direction in the front end region is first obtained from the original publication. Known.

This engagement is such that this engagement takes place when the displaceable furniture part is first fully inserted.

Starting from this prior art, in DE 20 2005 005 489 it is proposed that the telescopic guide is designed so that the axial joining of the furniture part to the extension rail under all circumstances is ensured after the movable furniture part is first closed or inserted. This telescopic guide is obtained in that the insertion restrictor is positioned in the front end region of the extension rail, which presses the front end of the center rail or guide rail if the extension rail is not yet fully inserted. The latch member that engages the latch cam in the opening and / or latch groove of the extension rail is pivotable from the insert containment position.

Thus, the engagement between the extension rail and the furniture part is fixed so as to be automatically cut off in the insertion direction first just before the extension rail reaches its final insertion position and again only released after a successful engagement between the extension rail and the furniture part, The group is pivoted from the insertion containment position by means of engaging. This results in a more robust and effective mounting.

In addition, this design can be further optimized. The insertion restrictor thus rests on the front face of the center rail, which has a shear face generated by the cutting tool, which shear face is cut rounding (first cut side), joint face. ), And fracture surface (cracks with curl). Sometimes this curling proves to be an obstacle during installation.

It is an object of the present invention to at least mainly solve this problem and to limit the configuration according to this kind so that high mounting safety is achieved while avoiding the above-mentioned problems.

The present invention achieves the subject matter of the claims 1 through.

Advantageous embodiments may be deduced from the dependent claims.

According to the invention, the latch member has two latch lugs, and the extension rail has two or more cuts positioned to be offset from each other in the inserting direction of the drawer, and the latch lug and the cut portion are mounted. In which only the first latch lug is positioned to engage the first cut or the second latch lug to engage the second cut.

However, during insertion, if the inertia force of the drawer is temporarily greater than the friction force of the latch lug in the cutout, for example when it collides with the damper, the first latch lug is separated from the cutout. The drawer then slides through the extension rail and the second latch lug engages the second cut. Thus, the second mounting position is reached simply and reliably, in which the drawer has a front panel that is optimally placed in the insertion position. This type of mounting is simple and reliable.

The aforementioned conditions may be carried out by means of a damped self-retractor, which is located on the telescopic guide over at least a portion of the elongation path, for convenience, preferably for the spring-supported retraction of the drawer.

The arrangement according to the invention is used to implement a safety function already at the time of initial pre-installation and to securely and securely couple the drawer to the side frame. The first cut is positioned and / or provided on the longitudinally extending rail so that the first latch lug securely arrives upon initial insertion of the drawer, thereby engaging the lug therein.

This pre-engagement position ensures that the members are not separated from each other until the drawer's final latch engagement position of the drawer, which may no longer slip, after the additional opening and closing is sufficiently strong to collide with the damping self-contractor. It is also fixed when the drawer is premounted.

In particular, the spacing of the stop faces of the latch lugs with respect to the stop at the cut is preferably smaller than the spacing of the corresponding stop faces of the cut.

Insertion restrictors provided in the prior art become unnecessary with the problems accompanying such insertion limiters.

DETAILED DESCRIPTION Hereinafter, the present invention will be described in detail with reference to the drawings based on exemplary embodiments.
