Description

Stretchable material guide for furniture parts that can be displaced from the body of the furniture {TELESCOPIC GUIDE FOR A FURNITURE PART THAT CAN BE DISPLACED IN THE BODY OF A PIECE OF FURNITURE}

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

Flexible material guides are for example published in DE 20 2005 005 489 U1, depending on the type.

Accordingly, the publication firstly displaces the furniture part in the furniture body in such a way that it is fixed in the axial direction and also in the transverse direction with respect to the furniture part in the front end region of the operating rail. The furniture part is joined to the working rail.

It is also proposed in DE 20 2005 005 489 that the flexible material guide is designed in such a way that the axial engagement of the operating part with respect to the working rail under all circumstances is ensured after the movable furniture part is first closed or pressed in. This is achieved by the insertion limiter being pressed against the front end of the guide rail or the center rail when the insertion limiter is located in the front end region of the actuation rail and the actuation rail is not fully pressurized inward. The latch element that engages the latch cam in the latch recess and / or opening of the actuation rail is pivotable from the insert blocking position.

 Thus, the operating rail is initially blocked automatically in the inserting direction before the operating rail is secured to the coupling between the furniture parts and reaches the final insertion position and is only released again after successful coupling between the operating rail and the furniture parts. This results in a more stable and optimized mounting.

The object of the present invention is to improve the design, in particular for high mounting reliability.

The present invention is achieved by the main configuration of claim 1.

Thus, the insertion limiter hooks around the guide rail or the central rail, in particular the front end of the guide rail, and the insertion limiter has one or more spring areas, which spring areas are provided as soon as the furniture part is pulled outwards. It is reset from the position surrounding the rail.

The present invention utilizes and improves the advantages of the prior art depending on the type. Thus, because of the hook-like wraparound of the guide rails, they are always securely fixed, and the elastic properties of the latch control components pivot in reverse from the blocking position for complete insertion in any case as soon as they are extended after mounting. Run

The engagement behind the free end of the guide rail is particularly simple to implement the design. The shape on the center rail is preferred in this regard.

According to a preferred embodiment, the adapter unit has a control curve to actuate the spring region of the latch control portion. Such control bends are useful when designed and applied to one or more spring areas in a manner that utilizes control bends, one of which is the hook section on the latch control part being guided or centered after the movable furniture part is removed from the telescopic material guide. It can be tensioned in such a way that it automatically moves back into the position to be joined behind the rail.

In another embodiment of the latch control portion as a metal spring, the action of this control curve or another action on the metal spring can be omitted. The spring is automatically released when the drawer is first pulled out.

Useful embodiments are disclosed in the dependent claims.

The invention is explained in detail hereinafter with reference to the drawings on the basis of an exemplary embodiment.

A stretchable material guide for a piece of furniture, such as a drawer, which is guided to be displaceable within the furniture body, is indicated in its entirety by reference numeral 1 in FIG. 1.

This telescopic material guide comprises an actuating rail 2 as clearly shown in FIGS. 2 and 3, which actuated rails and a displaceable guide rail 4 fixed to the marked furniture body 3 (FIG. 10). Can be combined into furniture parts. The central rail 5 with increasing extension length located between the operating rail 2 and the guide rail 4 can be optionally designed. The central rail can be seen in FIG. 10 showing a cross section through a flexible material configuration having a roller body between the central rail 5 and the rails 2, 4, 5.

The displaceable furniture part is simply referred to as a forward drawer. Such terminology is not to be understood as limiting, and is referred to as a "front" or "back" or "top" and "like a word associated with a drawer mounted in a body that can be pulled out, respectively. Terms such as "bottom" are not to be understood as limiting, where the front panel is typically referred to as "in front" and the drawer floor is as "on the bottom". It is referred to.

Overall, the drawer-side adapter unit 6, which also preferably functions as a latch element for latching on the actuation rail, and the insertion limiter 7 pre-mounted on the actuation rail are displaced into the actuation rail. To connect the possible furniture parts and / or to fasten the furniture parts on the working rail 2.

The adapter unit 6 is used for joining the actuation rail 2 to the drawer, in particular for joining the actuation rail 2 to the drawer frame 8 which is provided as a sheet metal part or for example configured on the sheet metal. .

The adapter unit 6 may be implemented in one or multiple parts. In a preferred embodiment there are two parts and a first adapter part 9 made of sheet metal and a second adapter part 10 made of plastic which is connected to the first adapter part to form a pre-assembled unit. do.

The first adapter part 9 is implemented in such a way that it can be coupled to the lateral frame 8 of the furniture part which is displaceably mounted.

To this end, the first adapter part 9 is preferably implemented as a punching / vent part made of sheet metal and preferably the lateral frame of the displaceable furniture part is formed by clinching the first adapter part ( 9) is formed in such a way that it can be permanently connected.

The first adapter part 9 is connected and latched into the second adapter part 10 and the second adapter part preferably comprises plastic. The second adapter part 10 is embodied in a way that can be latched on the actuation rail 2. The first adapter part and the drawer frame or the first adapter part 9 and the second adapter part 10 are in principle also embodied as one part.

The actuating rail 2 and the second adapter part 10 have a corresponding connection element 11, the corresponding connection element here preferably having a lower projection 12 on the second adapter part 10 (FIG. 3) and preferably as a window-like cutout or recess 13 (Fig. 2) on the upper side of the actuating rail 2.

The protrusion 12 comprises multiple webs 32 which are preferably joined at a slight spacing in the recess 13 when the multiple webs reach.

The first and second adapter parts 9, 10 are mutually assembled units in a pre-assembled unit by the latch means 28 on the second adapter part 10 which are coupled in the cutout 29 of the first adapter part 10. Quick and tight connection is possible.

A section 30 extending completely or essentially parallel to the actuation rail 2 is embodied on the second adapter part 10 and provided with a control curve 23 on the side of the section facing towards the actuation rail. And the control curve is designed and formed in such a way that the spring region on the insertion limiter is tensioned (as described in detail below). The section 30 also has a protrusion 27 for engaging under the beveled surface 26 of the base portion.

In order to assemble and draw the drawer on the actuation rail 2 in the axial direction, it is necessary to mount the drawer on the actuation rail in such a way as to ensure the engagement of the projection 12 in the window-shaped cutout 13.

However, in order to ensure that the protrusions 12 and the incisions 12 are engaged with each other in such a way that the drawers are pressed and / or closed inward to have the front panel as close as possible to the furniture body, the insertion limiter 7 This insertion limiter ensures that the guide rail can be mounted relatively far behind the furniture body.

The insert limiter 7 also ensures a combination with the adapter unit 6 so that the drawer is fixed on the end on the front panel side which is raised from the working rail 2 by snapping and / or latching engagement.

Insertion limiter 7 is implemented here in two parts, which in one embodiment is also preferred but not required. The insert limiter comprises a base portion 14 which can be fixed on the actuating rail 2 and a pivotable latch control portion 15 which is fixed thereon but positioned to be partially movable relative to the base portion, FIG. 4. Are shown as individual parts.

The base portion 14 comprises plastic as shown in FIGS. 1 to 6 cost-effectively.

It further has one type of stopper section 16, which is used in the operating rail 2 from the front end of the stopper section using this stopper section. A flange section 25 is provided at the front end of the stopper section 16 and the flange section is adjacent to the shoulder 17 and extends parallel to the working rail 2 on the outside.

In the insertion direction x, the rear end of the shoulder 17 passes through the release lance 18 extending downward via a beveled face 26 so that the release handle 18 is radially in the direction of extension. And / or perpendicularly protrude somewhat further outwards relative to the show rate 17 from the actuation rail 2.

The beveled surface 26 extends in the second section 26a both diagonally downward and in a diagonal direction perpendicular to the actuation rail 2 and only in the diagonal direction perpendicular to the actuation rail. Extend within 26b.

One or more of the sections of the beveled surface 26 have protrusions 27 on the second adapter portion 10 that engage below, in the final mounting position where the drawer is fixed to lift from the working rail 2 at the front end. Beveled surfaces are therefore particularly important.

To release below and / or behind this engagement, in the extended state of the drawer, the handle 18 is pressed in the direction y perpendicular to the actuation rail 2 such that the beveled surface 26 passes over the protrusion 27. Move and release under the coupling. Thus, the release of the drawer is not only easy, but especially quickly if desired. This principle is preferably applied in all the embodiments shown.

A slot 19, such as a T-groove, is provided in the show rater 17 of the base portion 14, in which the first spring region of the latch control portion 15, here a spring tongue 20, is provided. Coupled to the mounting position, the spring tongue 20 is firmly held, supported and guided on the base portion 14.

From FIG. 4, the latch control portion 15 is made of plastic. According to another embodiment, the sheet metal may be included.

It may be fixed to the base portion 14 in a manner that is partially movable relative to the base portion 14 after fixing. Theoretically it may also be implemented in one piece with the base part 14 but the spring region may be partially movable.

The baseplate of the latch control portion 15, which acts as a torsion spring and can be fixed to a free end on the base portion, and the latch control portion 15 pivots about the base portion 14 around the axis of rotation of the base portion. A pin 21 protruding from 22 is used to secure the latch control portion 15 to the base portion 14.

According to FIGS. 2 and 3, the pin is fixed on the free end to one type of hollow cylindrical receptacle 33 on the base portion 14. This torsional spring forms a first spring region on the latch control portion 15.

In addition to the pin 21 on the baseplate 22, which is also provided with a second spring region, the latch control portion 15 also includes a deformable spring tongue 20 attached to the baseplate 22, One free end section thereof passes through the slot 19 of the shoulder 17 of the base portion 14 and controls on the second adapter portion 10 in such a way that the spring tongue 20 moves and is tensioned as soon as the drawer is inserted. It works with a bend or face 23.

The latch control portion 15 also includes a hook section 24, the hook section being disposed around the free front end of the guide and / or body rail 4 during initial mounting (FIGS. 5A, 6A, 7A), so that the hook The section surrounds the free front end of the guide and / or body rail so that the torsion spring is relaxed.

At this time, the mounting execution is described in more detail based on the order of the ordered mounting image, and the sections of the elastic material guide element are sometimes not shown for easier understanding.

The adapter unit 6 is already fastened at the factory to the drawer frame 8 and the insertion limiter 7 is fastened to the flexible rail configuration (preferably one each in each lateral frame of the drawer).

After preassembly, the base portion 14 also has a stopper section 16 coupled to the actuating rail 2 and assembled thereon as described above and the latch control portion 15 via the base 21 via the pin 21. Assembled to move on portion 14. The latch control portion is biased relative to the base portion 14 in such a way that the hook section 24 surrounds around the front end of the guide rail 4 in the pressed state of the actuating rail 2.

As described above, in this state, the first spring region, i.e., a pin 21, such as a torsion spring, is relaxed so that the actuation rail extends beyond the front end of the guide rail 4, and with the rear or inner edge of the flange 25. It extends by a small distance, corresponding to the spacing between the inner edges of the hook section 24 (see FIG. 6A).

In practice, the protrusions are for example about 1 to 3 mm. This position is fixed by assembling the insertion limiter 7 in advance.

In this regard, preassembly can be carried out, for example, in advance at the "factory".

The actual mounting at the "final customer" can be started in this case by placing the drawer on the pressure actuating rail 2 and subsequently pressing the drawer.

Because of the gravity (z direction) the drawer is rearward and / or on the working rail 2 until the projection 12 on the second adapter part 10 and / or on the bottom side of the adapter unit falls here into the recess 13. Pressurized in the insertion direction x (6a and 6b and 7a and 7b as well as FIGS. 5a and 5b) (Figs. 5c, 6c and 7c), and the second adapter part 10 is provided by a projection 27 It spreads open and operates below the beveled surface 26 before reaching the recess 13. When the protrusion 12 engages in the recess 13, the first adapter portion 10 is relaxed so that the second adapter portion 10 and / or the adapter unit and the operating rail 2 recognize each other. And possibly latched to sound (5c, 6c, 6d).

Since the projections 27 engage below the base portion 14 of the insertion limiter 7, the drawers are not only fixed in the retracted and extended direction but also secure the unintended rise of the actuating rail 2.

Since the working rail 2 is pulled slightly relative to the guide rail 4 by the pre-assembled unit, it is preferable to mount the elastic material guide 1 deeper in the furniture main body.

This advantage is also intended to allow the drawer to be used to be somewhat retractable without protruding up to the contact of the front panel on the furniture body, with the control bend 23 and insertion limiter 7 on the adapter unit 6 being hook sectioned. Designed and applied relative to each other in such a way that 24 is sufficiently moved and pivoted here, the drawer is then opened from the starting position of FIG. 5A and the drawer is then pressed inward so that the base portion 14 is no longer Not placed between the flange section 25 and the end of the guide rail 4, the actuation rail 2 can be pressed further inward by this distance.

In this way, the spring tongue 20 is deflected perpendicularly to the direction of extension.

As soon as the actuating rail 2 connected to the drawer frame 8 via the adapter unit 6 is now separated from the guide rail 4 in the extending direction, the spring force of the tensioned spring tongue 20 is rearward-here 6D, 7D, the hook section 24, similar to the spring force, is pivoted against the spring force of the pin 20, from the engaged position inside the base portion 14 when the drawer is pushed back inwards. Is no longer disposed between the flange section 25 and the end of the guide rail 4, so that it can be pressed further inwards (FIGS. 6E, 7E).

As already described and shown in FIG. 6F, for example, in the position of FIG. 6C, the protrusion 12 on the adapter portion 10 is snapped into the recess 13 and / or the second adapter portion 10. The protrusion 27 of the second adapter part 10 and / or the adapter unit 6, which is latched by a spread of and which projects in the direction of the actuation rail 2 perpendicular to the direction of extension, is the base part. Coupled under one of the two sections 26a, b of the beveled surface 26 on (4), the reverse second adapter portion 10 and / or the adapter unit 6 and the entire drawer are actuated. Is fixed against the rise.

To allow the drawer to be released again from the actuation rail, the handle 18 is pushed inward as previously described so that the shoulder or protrusion 27 described above can be released from the engaging below, so that the drawer is raised To be possible. Thus, the hook section 24 is pivoted outwards because of the release of the pin 20 like a torsion spring, so that the hook section is again wound around the guide rail 4 the next time the actuation rail is pressed inward.

On the rear end (not shown here), the drawer frame is fixed on the C-hook to prevent it from being raised, for example in a conventional manner. A self-retractor device, preferably having a damper (not shown here) 9, may be located between the actuation rail and the guide or body rail.

The insert limiter is provided according to FIGS. 1 to 7 in such a way that the hook section 24 is pivoted inward into the actuation rail 2 when the back of the guide rail 4 is released. Alternatively, it is also possible to pivot outward with respect to the guide rail 4.

1 to 7 show a first modification.

8a to 8d show a second variant, wherein the spring tongue 20 is here supported by a coiled spring 34 so that these elements are connected in the second spring region. The functionality is basically the same. The control bend 23 on the adapter unit first causes the hook section 24 to pivot back when the drawer previously engaged on the actuation rail is pulled back, so that the actuation rail is pushed back inwards (FIGS. 8A-8D). ).

9 shows one embodiment, in which the latch control portion 15 comprises a metal, a sheet, preferably a steel sheet, to show the spring characteristics and / or one or more spring regions 35, 36. Have

The latch control portion 15 of FIG. 9 again has a hook section 24, which surrounds around the guide rail 4 in a pre-mounted position (FIG. 9A).

Again having spring regions 35, 36, one of them, the spring region 35 is implemented like a leaf spring and the other of these, the spring region 36 is operated like a torsion spring.

A spring region 35, such as a leaf spring, supported on the receptacle 37 of the base portion 14 is implemented on one end of a spring region 36, such as a torsion spring or also a pin. A web 38 having a hook section 24 for enclosing around the guide rail 4 is carried out on the other end of the spring region 36, such as a torsion spring (FIG. 9A).

The latch control portion 15 is initially mounted in a relatively severely curved manner such that a leaf spring, such as a leaf spring, is held in the inner receptacle 37 of the base portion 14 ′ so that the region like a torsion spring ( 36) is relaxed. In this position, the hook section 24 is wrapped around the free end of the guide rail 4 (FIG. 9A).

Under the action of the control curve 23 on the adapter unit 6, in particular on the second adapter part 10, the leaf spring region 35 is pressed flat, so that the hook section 24 has a torsion spring region 36 ( Even for the action of FIGS. 9c, 9d), as soon as the drawer is extended after being released from the guide rail 4, it is pivoted outward from the engaged rear position, and the spring region 36, such as a torsion spring, is tensioned, so that the drawer is again inside It can be fully pressurized when pressurized into (FIG. 9E).

The actual support of the drawer on the working rail is carried out as in FIGS. 1 to 7 (by protrusions 12 and 17).

Spring region 36, such as a torsion spring, returns back to the back engaged position of FIG. 9A, similar to the typical embodiment of FIGS. 1-7 after the spring is removed again.

The formation of the latch control portion from metal, in particular spring sheet steel, is particularly effective even after very many years, for example if the drawer is removed from the furniture body and then remounted after moving, for example, the special performance and reliability of the torsion spring section 36 Has the advantage of.
