Description

TELECOPIC GUIDE FOR A FURNITURE PART THAT CAN BE DISPLACED IN THE BODY OF A PIECE OF FURNITURE}

The present invention relates to a piece of telescopic guide for furniture that can be displaceably arranged in a cabinet of a piece of furniture, such as a drawer, pull-out section, and the like. A sliding rail that can be hooked to the furniture member by a latching element that can be secured to it, a guide rail that can be secured to a cabinet of a piece of furniture, and optionally a guide rail to increase the extension length. And a center rail arranged between the sliding rails.

The general type of telescopic rail itself is known and is practiced in many embodiments.

Joining the sliding rail with the sliding rail in such a way that the furniture member is displaceably arranged in the cabinet of a piece of furniture in such a way that it is fixed to its leading area with respect to the sliding rail, more specifically axially and across this axial direction. It is also known to make.

Conventional joining methods are practiced in such a way that a join is created when the displaceable furniture member is fully inserted for the first time.

The conventionally used structure cannot effectively guarantee that axial coupling is achieved in all cases, so that if the furniture member is not joined to the sliding rail, the furniture member will be completely separated from the sliding rail when the furniture member is first pulled out. There is a risk. This is associated with the risk of serious injury.

It is a primary object of the present invention to construct a general type of telescopic guide in such a way that the axial coupling of the furniture member to the sliding rail is ensured under any circumstances once the movable furniture member is closed or inserted for the first time.

This object is achieved in accordance with the invention in which an insertion restrictor is arranged in the leading region of the sliding rail, the insertion restrictor being supported against the front end of the center rail or guide rail when the sliding rail is not fully inserted, It may be pivoted out of the insert-blocking position by a latching element that engages a latching cam in a latching recess.

Thus, the present invention ensures the engagement between the furniture member and the sliding rail by forcibly blocking the sliding rail in the insertion direction just before the final insertion position is achieved, and by turning the insertion restrictor out of the insertion-blocking position causing the engagement. It is based on the core concept of merely releasing the engagement again for subsequent engagement between the furniture member and the sliding rail.

That is, in all cases the user can know when the furniture member is fully inserted for the first time, thus eliminating potential operating errors.

Further features of the present invention are the contents of the appended dependent claims.

In FIG. 1, a telescopic guide for a furniture member, which can be displaceably guided in a cabinet of a piece of furniture, such as a drawer, is generally indicated by reference numeral 1.

Such telescopic guides may, in a known manner, comprise a sliding rail 2 which can be connected to a displaceable furniture member, a guide rail attached to a pointed cabinet 3 of a piece of furniture; 4) and a center rail 5 which extends to an extending length and is arranged between the sliding rail 2 and the guide rail 4.

2 shows the contour of the side frame 6 of the drawer, in which a latching element, generally indicated by the reference numeral "7", is fastened in a known manner by known clip connectors, which clip connector is telescopic It is used to form a bond between the sliding rail 2 of the guide 1 and the drawer.

3a and 3b show a latching element provided with clip means 7a for fastening to the side frame in the region of a bearing and stiffening web 6a (FIG. 2).

The latching element 7 is also equipped with a latching nose 7b on the resilient leg 7c, which latching nose 7b is coupled in the recess of the sliding rail in a manner not yet described to form a sliding rail ( 2) is used to join the drawer.

The latching element 7 also has a handle 7d which, if necessary, allows the latching nose 7b to be moved out of the recess of the sliding rail 2 so that the engagement is released.

4 is a bottom view of the side frame 6 with latching elements 7 assembled on the support reinforcing web 6a.

5a to 5c show several perspective views of the leading region of the sliding rail 2, some of which are cross-sectional views.

It is clearly confirmed that this sliding rail 2 is provided with one or more recesses 2a, where the latching nose 7b of the latching element 7 described above is adapted for the axial connection of the movable furniture member and the sliding rail 2. ) Can be combined.

It is also clearly seen from FIGS. 5A-5C that an insertion limiter 8 is provided in the tip region of the sliding rail 2, which insertion stop 8 is a stopper 8a. This stop 8a can be inserted into the sliding rail 2 and has a shaped spring 8b attached to the stop 8a. The shaped spring 8b is constructed in such a way that one or more lateral projections 8c are continuously loaded in the direction of the recess 2a of the sliding rail 2 by elastic force.

In the initial position-that is, when the lateral projection 8c is pivoted in the direction of the recess 2a-the tip 8d of the shaped spring 8b projecting into the interior of the sliding rail 2 is the center rail. It is in the displacement path with respect to (5).

This means that the sliding rail 2 can only be initially pressed in the insertion direction so that the insertion restrictor 8 is supported on the face of the leading end of the center rail 5 as shown in FIG. 7A. Only when the latching nose 7b of the latching element 7 engages into the recess 2a can the spring 8b shaped into the position visible in FIG. 7B be pivoted. In other words, the tip 8d of the shaped spring 8b is moved out of the displacement path of the center rail 5. Thus, the sliding rail 2 and, in addition, the drawer or any other desired furniture member locked with the sliding rail 2 can slide completely into the interior of the body 3 of a piece of furniture. At the same time, however, this ensures that the sliding rail 2 is connected to the displaceable furniture member.

7b shows the situation given immediately after the connection which has been achieved between the sliding rail 2 and the movable furniture member. FIG. 7C shows that the sliding rail 2 slides into the cabinet 3 of the furniture up to the maximum insertion position after achieving the connected state.

6a and 6b show the telescopic guide according to the invention just before the deployment of a movable furniture member such as a drawer 9 with a side frame 6 and a latching element 7 fixed to the side frame 6. (1) is shown. 6b shows the drawer 9 after being positioned on the sliding rail 2.

By inserting the drawer 9 into the cabinet 3 of a piece of furniture, a procedural step according to FIGS. 7a to 7c is created, which, as described above, comprises a sliding rail 2 and a drawer ( If the connection between 9) is ensured, it is ensured that the drawer 9 can only be fully inserted into the interior of the cabinet 3 of a piece of furniture.

The treatment stability of one piece of furniture is thereby significantly increased, in particular the risk of injury being prevented as a result of the complete withdrawal of different furniture members or drawers from the cabinet of one piece of furniture.

As the embodiments clearly show, by way of example, the sliding rail 2 is provided with an additional recess 2b, which further projection 8e of the spring 8b shaped into this further recess 2b. ) Protrudes. This is, for example, as can be seen in FIGS. 8 and 9, a latching nose 7b located at a position different from the position in the above embodiment is provided in the latching element 7, or as shown in FIG. It may be useful if a latching nose 7b is provided in the latching element 7, ie the solution described above enables the use of a differently configured latching element 7.

The above description makes it clear that only minimal modifications to the flexible guide 1 and some additional components are necessary to implement the concept according to the invention. The largest constituents of the known telescopic guide can be retained, providing only an insertion restrictor 8 and inserting such that the effect can be released by the latching nose 7b of the latching element 7. It is only necessary to construct the limiter 8.

It is necessary for the arrangement according to the invention to function as an elastic force, by means of which it is shaped to pivot the projection 8c in the direction of the latching recess 2a or 2b and in the direction opposite to the latching nose 7b. The latching nose 7b of the latching element 7 is compressed into the recess 2a or the recess 2b so as to be larger than the elastic force of the spring 8b.

Of course, it should also be understood that the stop spring and leaf spring of the manner of a single piece product can also be integrated, for example also as a plastic material part.

It is also contemplated that such leaf springs may be replaced with rotatably mounted levers of one-armed or two-armed arms that are spring biased.

On the other hand, the above principle is not limited to guide rails having a rectangular cross section, but of course the protective receiving portion inside the hollow shape can be applied to all other guide rails, although appropriate.
