Description

 Telescopic guide for a slidably arranged in a furniture body

Mδbelteil

The present invention relates to a telescopic guide according to the preamble of claim 1.

Telescopic guides are known per se, so from the generic DE 20 2005

005 489 Ul.

Thereafter, it is initially known from this document, a furniture body slidably disposed in a furniture part to be coupled to the running rail such that the furniture part is fixed in the front end region of the running rail with respect to this, in the axial direction as well as transversely to the axial direction.

Moreover, it is proposed in DE 20 2005 005 489 to design a telescopic guide such that an axial coupling of the furniture part with the running rail after the first closing or insertion of the movable furniture part is ensured under all circumstances. This is achieved in that a Einschubbegrenzer is arranged in the front end region of the running rail, which abuts not fully inserted track at the end of the end of the guide rail or a center rail. The engaging with a locking cam in a latching recess or a recess of the track locking element is pivotally out of its slot blockage position.

Thus, the coupling between the running rail and the furniture part is ensured by the fact that the running rail in the direction of insertion is first forcibly blocked shortly before reaching the final insertion position and only after successful

Coupling between the running rail and the furniture part is released again. This leads to a safer and optimized assembly. It is the object of the invention to improve this construction, in particular with regard to a high installation safety.

The invention solves this problem by the subject matter of claim 1.

Thereafter, the insertion limiter surrounds the guide rail or the center rail, in particular the end-side end of the guide rail, hook-shaped and has at least one spring region, which causes a provision of the guide rail or the middle rail embracing position during the first extension of the furniture part.

The invention takes advantage of the generic state of the art and develops it further. Thus, by the hook-like grip of the guide rail is always a safe installation, the resilient property of the Aufraststeuerteils realized at the first extension after assembly in any case a swing back from the blockage position against complete insertion.

Constructively particularly easy to implement is the rear grip of the free end of the guide rail. The arrangement on the middle rail is, on the other hand, less preferred.

According to a preferred variant, the adapter device has a control cam for actuating the spring region of the Aufraststeuerteils. It is advantageous if this cam is designed and tuned to the at least one spring portion that one of the spring portions is tensioned so that the hook portion on Aufraststeuerteil after removing the movable furniture part of the telescopic guide automatically in the rear grip position on the guide or middle rail moved back.

In an alternative embodiment of the Aufraststeuerteils as a metal spring can be applied to this action of a control cam or other action on the Me- tallfeder even be dispensed with. The spring automatically releases when the drawer is first opened.

Advantageous embodiments can be found in the dependent claims.

The invention will be described in more detail below with reference to the drawing with reference to exemplary embodiments. Show it:

In Figure 1, the reference numeral 1 a total of a telescopic guide for a slidably guided in a furniture body furniture part such. B. called a drawer. As can readily be seen in FIGS. 2 and 3, this telescopic guide has a running rail 2 which can be coupled to a displaceable furniture part and a guide rail 4 fixed to an indicated furniture body 3 (FIG. An extension length increasing center rail 5, which is arranged between the running rail 2 and the guide rail 4, is optionally conceivable. It can also be found in Fig. 10, which shows a section through a telescopic arrangement with center rail 5 and rolling elements between the rails 2, 4, 5.

Hereinafter, the sliding furniture part is referred to as a drawer for the sake of simplicity. This conceptual assignment is not intended to be limiting, as are terms such as "forward" or "rear" or "upper" and "lower", each referring to common usage with respect to a pull-out drawer mounted in a body, in which: the front panel is usually referred to as "lying in front" and the drawer bottom as "lying down".

To connect the movable furniture part with the running rail or for fixing the furniture part to the running rail 2 serve a drawer-side adapter device 6, which as a whole preferably also the function of a

Latching element for locking on the running rail exerts, and a preassembled on the running rail insertion limit. 7

The adapter device 6 is used for coupling the running rail 2 with the drawers, in particular for coupling the running rail 2 with a drawer frame

8, which is designed for example as a sheet metal part or builds on such.

The adapter device 6 can be designed in one or more parts. Here it is in two parts in a preferred embodiment and comprises a first adapter part 9 made of sheet metal and a second A dapterteil 10 made of plastic connected to this to a preassembled unit. The first adapter part 9 is designed such that it can be coupled to the side frame 8 of the displaceably mounted furniture part.

For this purpose, the first adapter part 9 is preferably designed as a punched / bent part made of sheet metal and preferably designed such that the side frame of the movable furniture part can be permanently connected, for example by press-fitting on the first adapter part 9.

The first adapter part 9 is connected to a second adapter part 10 - locked here - which preferably consists of a plastic. The second adapter part 10 is designed such that it can be latched to the running rail 2. The first adapter part and the drawer frame or even the first adapter part 9 and the second adapter part 10 could theoretically also be formed as one piece.

The running rail 2 and the second adapter part 10 have corresponding connecting elements 11, here as a preferably lower projection 12 (FIG. 3) on the second adapter part 10 and as a preferably window-like recess or recess 13 (FIG. 2) on the upper side of the running rail 2 are formed.

The projection 12 consists of a plurality of webs 32 which engage in reaching the recess 13 preferably with a slight play in this.

The first and the second adapter part 9, 10 are connected by locking means 28 on the second adapter part 10, which engage in a recess 29 of the first adapter part 10, quickly and safely together to form a preassembled unit.

On the second adapter part 10 is in a mounted position wholly or substantially parallel to the running rail 2 extending portion 30 formed on its side facing the running rail a control cam 23 is formed, which is designed and shaped such that from her a spring portion of the Einschubbegrenzer is stretched (which will be described in more detail below). The section 30 also has the projection 27 for engaging under the inclined surface 26 of the base part.

In order to fix the drawer to the running rail 2 and to secure it in the axial direction, it is therefore necessary that it is mounted on the running rail, that the engagement of the projection 12 is ensured in the window-like recess 13.

However, in order to ensure that the projection 12 and the recess 13 engage in such a way that the thrust loads with its front panel as far as possible pushed up to the furniture carcass or can be closed, it requires the Einschubbegrenzers 7, which ensures that the guide rail can be mounted relatively far back in a furniture carcass.

The slide-in limiter 7 also ensures, in interaction with the adapter device 6, that the drawer is secured at the front-end-side end against being lifted off the running rail 2 by snapping or latching engagement.

The Einschubbegrenzer 7 is here - again in a preferred but not mandatory embodiment - formed in two parts. It comprises a base part 14 which can be fixed to the running rail 2 and a pivotable catching control part 15 which is fixed thereto and at least partially movable relative thereto, that is also shown as an individual part in FIG. 4.

The base member 14 is shown in FIG. 1 to 6 cost of plastic.

It has a kind of plug portion 16, with which it engages in the running rail 2 from the front-side end thereof. At the front end of the plug portion 16, a flange portion 25 is formed, to which a projection 17 connects, which extends here parallel to the outside of the running rail 2 to this. The insertion end x rear end of the projection 17 via an inclined surface 26 in a downwardly extending release handle 18, such that the release handle 18 protrudes relative to the projection 17 slightly further from the running rail 2 radially or perpendicular to the withdrawal direction to the outside ,

The inclined surface 26 extends in a first portion 26a both obliquely downwards and obliquely to the vertical to the running rail 2 and in a second portion 26b only obliquely to the vertical to the running rail.

The inclined surface 26 is of particular importance in that at least one of its sections is engaged in the final assembly position by the projection 27 on the second adapter part 10, which secures the drawer at the front end against lifting from the running rail 2.

To release this lower or rear grip is in the extended state of

Drawer pressed the handle 18 in the direction y perpendicular to the slide rail 2, which the inclined surface 26 moves past the projection 27, so that the lower handle is released. The release of the drawer is thus not only simple if necessary but also very fast. This principle is preferably used in all illustrated embodiments.

In the extension 17 of the base part 14, a T-groove-like slot 19 is formed in the mounted position, a first spring region - here a spring tongue 20 - the Aufraststeuerteiles 15 engages, so that the spring tongue 20 securely held on the base member 14, supported and guided.

The Aufraststeuerteil 15 of FIG. 4 is made of plastic. According to alternative embodiments, it may also consist of sheet metal.

It can be fixed to the base part 14 in such a way that it still remains movable in sections relative to the base part 14. It can theoretically also be integral with be carried out the base member 14, but then again in sections have movable spring portions.

To determine the Aufraststeuerteils 15 on the base part 14 is a projecting from a base plate 22 of the Aufraststeuerteils 15, torsion spring-acting

Pin 21 which is fixable at its free end to the base part and about the axis of rotation of the Aufraststeuerteil 15 is pivotable relative to the base member 14.

According to Fig. 2 and 3, the determination of the pin at its free end in a kind of hollow cylindrical receptacle 33 on the base part 14. This torsion spring forms a first spring portion Aufraststeuerteil 15th

The Aufraststeuerteil 15 includes in addition to the pin 21 on the base plate 22, on which a second spring region is further formed, here also on the base plate 22 attaching, deflectable spring tongue 20, the slot 19 of the projection 17 of the base part with a free end portion 14 interspersed and so cooperates with a control cam or surface 23 on the second adapter part 10, that the spring tongue 20 is moved and tensioned during the first insertion of the drawer.

The Aufraststeuerteil 15 further includes a hook portion 24 which is placed at the first mounting around the free front end of the guide rail 4 (Fig. 5a, 6a, 7a), so that it engages around it, the torsion spring preferably remains unstressed.

At this point, the assembly process is explained in more detail with reference to a sequence of consecutive assembly images, in which partial portions of the elements of the telescopic guide are not shown, to facilitate understanding. Beforehand, the adapter device 6 is already fastened to the drawer frame 8 and the slide-in limiter 7 to the telescopic rail arrangement in the factory (preferably one on each side frame of the drawer in an analogous manner).

The base member 14 engages after the pre-assembly further with its plug portion 16 in the track 2 and is fixed to this, which - as already stated - the Aufraststeuerteil 15 is fixed via the pin 21 movable on the base member 14. Here, the Aufraststeuerteil is deflected relative to the base member 14 so that its hook portion 24 surrounds the front end of the guide rail 4 in eingeschoben- nen state of the track rail 2.

As already mentioned, in this state, the first spring region, ie, the torsion spring-like pin 21 relaxed and the running rail by a small piece a (see Fig. 6a), corresponding to the distance between the inner edge of the hook portion 24 and the rear or ., Inner edge of the flange 25 extended beyond the front end of the guide rail 4 addition.

In practice, the supernatant is e.g. about 1 to 3 mm. This position is secured by the pre-assembly of Einschubbegrenzers 7.

In that regard, a pre-assembly is e.g. already "in the factory" feasible.

The actual installation of the drawer at the "end customer" can in this case begin with a placement and subsequent pushing of the drawer on the inserted track (s) 2.

In this case, the drawer is moved on the rails 2 to the rear or in the insertion direction x (FIGS. 5a and 5b and 6a and 6b and 7a and 7b) until the projection 12 at the bottom of the adapter device or here at the second A dapterteil 10th Gravity-assisted falls into the recess 13 (direction z) and engages in this (Fig. 5c, 6c, 7c), wherein by the projection 27 which runs under the inclined surface 26, before reaching the recess 13, a spreading of the second adapter part 10 takes place. When the projection 12 then engages in the recess 13, the first adapter part 10 relaxes, so that the second adapter part 10 or the adapter device and the running rail 2 noticeably and optionally also audibly engage with each other (5c, 6c, 6d).

Since the projection 27 engages under the base part 14 of the insertion limiter 7, the drawer is not only secured in the insertion and withdrawal but also against unintentional lifting of the running rail. 2

The fact that the running rail 2 was pulled out by the pre-assembly somewhat relative to the guide rail 4, a deeper mounting of the telescopic guide 1 in the furniture body is possible.

Thus, this advantage can also be used to ensure that the drawer is almost always retractable without protrusion to the system of the front panel on the furniture body, the insertion limiter 7 and the control cam 23 are so designed and matched to the adapter device 6 that the hook portion 24 at the next Opening the drawer from its initial position of Fig. 5 a moved so far, pivoted here, that he no longer between the end of the guide rail 4 and the next time the drawer is inserted

Flange portion 25 of the base member 14 is located so that the running rail 2 can now be further inserted by this way.

This is achieved in that the spring tongue 20 is deflected perpendicular to the withdrawal direction.

As soon as the running rail 2 connected to the drawer frame 8 via the adapter device 6 now releases in the withdrawal direction from the guide rail 4, the spring force of the tensioned spring tongue 20 pivots the hook section 24 against the spring force of the torsion spring-like pin 20 from the rearward grip position - here inwardly ( 6d, 7d), so that it is no longer between the end of the guide rail 4 and the Flanschab- during re-insertion of the drawer section 25 of the base part 14 is located, as a result of which it can be further inserted accordingly (FIGS. 6e, 7e).

As already explained and e.g. 6f, engages in the position of FIG. 6c, in which the projection 12 snaps into the recess 13 on the adapter part 10 or engages in cooperation with the spreading of the second adapter part 10, which in the direction of the running rail 2 perpendicular to Ausziehrichtung projecting projection 27 of the adapter device 6 and the second adapter part 10 the one of the two sections 26a, b of the inclined surface 26 on the base part 4, so that the adapter device 6 and here the second adapter part 10 and thus the entire drawer against lifting from the Running rail 2 are secured.

So that the drawer can be released again from the track, must - as already explained - the handle 18 are pressed so that the above-described approach or projection 27 is released from the lower handle, so that the drawer can be lifted. Immediately, the hook portion 24 pivots outward again due to the release of the torsion-spring-like pin 20, so that it engages around the guide rail 4 again during the next insertion of the running rail.

At its rear end (not shown here), the drawer frame is secured, for example, in a conventional manner to a C-hook against lifting. Between the running and the guide or carcass rail, a self-closing device, preferably with damper (not shown here) 9 may be arranged.

The insertion limiter is formed according to Fig. 1 to 7 such that the hook portion 24 is pivoted in its release from the rear grip of the guide rail 4 inwards into the running rail 2. Alternatively, it is also possible that it is pivoted relative to the guide rail 4 to the outside.

The first variant, Figs. 1 to 7. The second variant, the Fig. 8 ad show, in which case the spring tongue 20 is supported by a coil spring 34, so that these elements together form the second spring region. The function is basically the same. The control cam 23 on the adapter device in turn causes the hook portion 24 is pivoted back during the first extraction of the previously locked on the track rail drawer, so that the running rail can be further inserted (Fig. 8a-d).

9 shows an embodiment in which the Aufraststeuerteil 15 of a metal sheet, preferably a steel sheet which has resilient properties or one or more spring portions 35, 36th

The Aufraststeuerteil 15 of FIG. 9 in turn has a hook portion 24, with the guide rail 4 is embraced in the preassembled position (Fig. 9a).

It also has in turn the spring portions 35, 36, one of which - the spring portion 35 - leaf-spring-like and the other - the spring portion 36 is torsions spring-like.

At one end of torsionsfederartigen or pin-like spring portion

36, the leaf spring-like spring portion 35 is formed, which is in a receptacle

37 of the base part 14 is supported. At the other end of the torsion-spring-like spring region 36, a web 38 is formed with the hook section 24 for embracing the guide rail 4 (FIG. 9a).

In this case, the Aufraststeuerteil 15 is held after the initial assembly in such a way in the inner receptacle 37 of the base member 14 ', the leaf spring-like spring portion 35 is relatively strongly curved and the torsionsfederartige area 36 is relaxed. In this position, the hook portion 24 engages around the free end of the guide rail 4th

(Figure 9a). Under the action of a control cam 23 on the adapter device 6, in particular on the second adapter part 10, the leaf spring portion 35 is pressed flat, so that the hook portion 24 during the first extension of the drawer after its release from the guide rail 4 against the action of the torsion - Federbereichs 36 from the rear grip position pivoted out (Fig. 9c, 9d) and the torsion spring-like spring portion 36 is tensioned, so that the drawer can be completely inserted during reinsertion (Fig. 9e).

The actual stop of the drawer on the running rail is realized as in FIGS. 1 to 7 (by the projections 12 and 17).

The torsion-like spring portion 36 causes after an expansion of the drawer, the renewed snap back into the rear grip position of Fig. 9a analogous to the embodiment of FIGS. 1 to 7.

The design of the Aufraststeuerteils of metal, in particular spring steel, has the advantage of particular stability and reliability, in particular the Torsi- ons-spring portion 36 even after many years, if, for example, when removing the drawer to be removed from a furniture body and then re-assembled.
