Description

Device and method for mounting a guide rail assembly

The invention relates to a device and a method for assembling a guide s rail arrangement according to the preambles of claims 1 and 9.

When mounting a furniture drawer guide on a furniture body, it is necessary to anchor the body or guide s rail assembly - formed from a single or multi-part guide rail - on the furniture body or fasten. The guide s rail arrangement preferably consists of the combination of a guide rail with a guide rail angle or a plurality of guide rail angles.

It is known that the guide rail is designed in the manner of a guide angle, which has a fixable on the furniture body attachment leg which is attached to the furniture body by means of fasteners such as screws, pins or dowels.

Such arrangements are known, for example, from EP 0 791 313. A disadvantage of the arrangement is that the fastening pins are only equipped with teeth on one side and that they do not have a spreading element in order to achieve high strength during assembly.

It is also known to set Schubkastenausziehführungen on a piece of furniture using a fastener, wherein the fastener is braced by means of a clamping lever on the furniture body.

Such arrangements shows the generic DE 198 48 855 Al. A disadvantage of this construction is the additional design effort for the realization of the clamping lever. Furthermore, each tension lever located on the pullout guide must be actuated separately, which leads to an unacceptably high effort during assembly.

Against this background, the invention has the task of further simplifying the generic device and the generic method. The invention solves this object with respect to the device by the subject-matter of claim 1 and with respect to the method by the subject-matter of claim 9.

It thus provides, in particular, a method for assembling at least one guide rail arrangement of a pull-out guide of a drawer of a piece of furniture on a furniture carcass that has at least one guide rail arrangement and which has at least one or more fastening elements which can be brought into a more fixing position (s) is attached to the furniture body, comprising the following steps:

the guide rail assembly is preassembled with the at least one fastener on the furniture body, wherein the at least one fastener after preassembly is in the less fixing position, and - the at least one fastener is by at least one or more movements of the pre-assembled on the rail drawer and / or moved by at least one or more movements of the running rail from the less fixing position to the stronger fixing position.

By the device according to the invention and by the method according to the invention, the mounting of the guide rail assembly on the furniture body is very simple.

First, the guide rail assembly is pre-assembled on the furniture body by the guide rail assembly is pressed with at least one fastener on the furniture carcass wall. The fastener takes a slightly fixative, but overall rather loose position.

If the drawer is guided by means of two guide rail assemblies on two opposite sides, this pre-assembly is carried out according to the other two each opposite furniture carcass walls. Then the running rail or the entire pre-assembled drawer with the preassembled track and possibly a center rail on the pre-assembled guide s rail arrangement placed and once retracted and extended. Alternatively, the determination is made by the method of each individual drawer slide.

By at least one of the two movements "placing the drawer", "first insertion and removal of the drawer" or "method of drawer slide" is then the at least one fastener from one of its looser pre-assembled position in a more rigid position - a "lock s position " - emotional.

That this type of quasi-tool-free installation or fixing and anchoring of at least one fastener is particularly simple and straightforward, is obvious.

There are neither special constructive elements such as movable levers or the like. provide on the drawer or on the drawer slide, it is still necessary to set the at least one fastener with special tools or the like. to do.

By this device and the method for their operation, it is also possible to reduce the height of the guide rail angle to the dimension "top edge rail".

As an alternative to a continuous guide rail angle, the guide rail arrangement can also be formed from two or more separate guide rails. The reduction of the overall height as well as the use of separate angles lead to a significant material saving.

Another advantage is that the mounting points on the guide rail angle no longer need to be accessible for tools for assembly. The hole spacing can be aligned with the hole spacing known from furniture systems "System 32 ^® " and "System 25". Advantageous variants of the invention can be found in the dependent claims. The invention also provides the subject matter of claims 7 and 18.

The invention will be described in more detail below with reference to the drawings by means of exemplary embodiments, wherein further advantages of the invention will become apparent. Show it:

Figures 11 to 12 are plan views of other sections of a drawer with a pre-assembled drawer slide on a cabinet wall.

FIG. 1a shows a partial area of a pull-out guide 1 for drawers, which has a carcass arrangement or guide rail arrangement 2 with at least one guide rail, which is designed as a guide rail, and a running rail 3 which is attached to a drawer 4 (FIG. see FIG. 5) and if necessary a center rail 5 between the running rail 3 and the guide s rail arrangement 2.

The slotted area for spreading the fastener was not drawn in favor of a simplified representation. The spreading of such elements is known from the prior art as described above.

The guide rail assembly 2 has the guide rails angle 6, which has a mounting leg 7 for fixing the guide s rail assembly 2 on a not shown in Figure 1 furniture carcass wall (but see the reference numeral 19 of the furniture carcass in Fig. 9 ff) and a rail leg 8 with a rail-like contour, the like as the actual rail support surface for the drawer with the running rail 2, the middle rail 5 and possibly provided rolling elements or the like. serves (see also Fig. 10).

The fastening leg 7 is provided with a plurality of through-holes 9, which are designed to receive one-piece or multi-piece fastening elements 10, which in the present case are designed as expansion anchors.

It is possible to insert only one of the through holes 9 of one of the fasteners. The hole pattern can also be designed in a different way than in FIG. In particular, it is possible to offset each other axially or in the pull-out direction forming a plurality of hole patterns with one or more through holes in the guide rail angle.

Of course, the invention is also not limited to a single fastener on a guide s rail assembly 2, but it is possible to set each guide s rail assembly with multiple fasteners on the furniture body 19.

It is also understood that - although only the determination of a guide s rail assembly 2 is illustrated in Figure 1 - preferably two guide s rail assemblies 2 are set on opposite sides of the drawer in the illustrated manner in the assembly of a drawer. The claims are not restrictive in this regard, but each include, if "at least one" element is mentioned, also the option that several of the respective elements concerned in the respectively claimed kind or in terms of the method to be assembled.

According to its preferred embodiment, the at least one fastening element 10 is formed as a one-piece or multi-part expansion dowel, which is movable by means of a movement of an actuating element 12 from a non-splayed position to a splayed position, although this is not apparent from Figure 1.

With regard to the basic construction of an expansion anchor, reference is made to DE 198 48 855 A1 or DE 27 21 403 A1 already mentioned in the introduction, according to which the expansion anchor is designed in such a way that a movement of e.g. axially adjustable inner expansion cone expanding jaws are extended. In itself, it has also been considered to bring fasteners by pivoting fittings in a final assembly position. However, it was not recognized that running rails and / or drawers are suitable to lock in a simple manner preferably by means of a linear movement of the drawer or the running rail, the fasteners 10 of the guide rail (s) 2.

Thus, it is preferably provided to plug at least one of the fixing elements 10 to be fixed for pre-assembly through one of the fastening holes 9 and the unit thus preassembled with the guide rail (nanordnung) 2 then to fix at a provided with corresponding holes or blind holes furniture body wall, without the first fixing the fastener 10 is already moved to the expansion position in which he securely fixes the sschienenanord- guide on the furniture body wall and anchored so that they without a back movement of the Fastening element from the spread position can not be solved again by the furniture carcass wall.

The fastener 10 is used against rotation in the mounting holes 9, conceivable here is a square Execution of the mounting hole and the upper portion of the fastener.

According to the invention it is further provided that the drawer is designed in its entirety with the pre-mounted rail and possibly the pre-mounted center rail and sized relative to the furniture body that either the first placement of the drawer on the pullout guide and / or the first insertion or extension of the drawer on the guide sschienenan- order the fastener 10 is moved from its less-fixing position to its stronger fixing position.

With respect to the fastener 10, this means that an actuating element (or portion) 12 of the fastener 10 is moved from its non-splayed position to its splayed position.

In this way, the fastening element is moved into the expanding position virtually simply by placing the drawer 4 or, more preferably, by the first extension and retraction of the drawer 4, thus anchoring the guide rail arrangement to the furniture cabinet wall.

Of course, it is possible to set several of the attachment selemente 10 on the furniture carcass wall in the first movement.

As can be seen from the figures, it is possible to implement these measures by various means. Thus, as shown in FIG. 1, a projection 11 projecting in the direction of the furniture body can be formed on the running rail 3, which is designed and dimensioned such that it moves the actuating element 12 of the fastening element, in particular of the fastening element 10, from a first position into one pivoted second position, whereby the fastener 10 is moved accordingly from its non-splayed position in its spread position, which here corresponds to a movement from a less-fixing position into a stronger fixing position. This movement includes an angle change of 90 °. The fastening element is secured against rotation in the through-hole 9, also conceivable is a square version of the through-hole 9 with the expansion element of the fastening element 10 pressed in from the rear. The expansion element in the upper region is preferably designed as a square. The term "protrusion" is also to be understood as meaning that the running rail 3 as a whole is made so broad that it anchors the fastening element 10 during movement, but has recesses in the region of which it can be placed in the region of the preassembled fastening elements 10 In this case, virtually the wider area of the running rail 3 forms, in addition to the recesses, the "projection" or the "before jumps".

This movement results from the interaction of the figures Id, Ie and If. In Fig. If, however, was not shown exactly for drawing reasons, as spread apart the jaws, but this position was only indicated by dashed lines.

FIG. 1 d shows how the projection 11 initially moves toward the actuating element 12 during the first insertion of the drawer with the running rail onto the guide 2 and, as can be seen from FIG. 1e, pivots and finally moves into the end position of the FIG. in which the fastener is moved to its spread position.

According to Figure 1, the actuating element 12 of the fastening element is designed as a rotary member having a here perpendicular to the longitudinal axis A of the fastener 10 extending leg 12a, which formed as a pin projection 11 on the running rail 3 during insertion of the running rail 3 from the position of the figure Id in which the figure If pivots. It is also conceivable to design the actuating element 12 -as shown in FIGS. 2 and 3 -as a movable actuating element in the direction of the longitudinal axis A of the fastening element 10, which is designed such that the expansion function of the fastening element is activated during axial displacement of the actuating element.

3, the movement of the actuating element 12 in the axial direction is effected by a projection 11 arranged on the running rail 3.

In this case, the projection 11 and / or the actuating element 12 are preferably formed so that obliquely to the longitudinal axis A of the anchor one or more cooperating inclined surfaces 13, 14 facilitate the movement of the running rail 3 in the direction X in a direction perpendicular to the X movement of the actuating element 12th implement. The projection 11 is made in Fig. 2 and 3 as an angle strip of a metal sheet, which is simple and inexpensive.

Figure 4 shows a complete pullout guide for mounting on a furniture carcass wall. Evident are the catch hook 13 on the running rail and the middle rail 5 and the running rail and the one-piece here s rail guide 6th

As can be seen, two of the hole patterns are provided with through-holes 9, wherein one of the fastening elements 10 is inserted through in each case one of the through-holes of the two axially offset hole patterns.

There are also two axial directions or main directions of extension of the rail 3 staggered projections 11 are provided, which are designed according to a variant such that almost simultaneously at the same time when inserting and removing the pullout guide (especially during the first insertion of the pullout 1), the movement of the actuating element 12th the fastener 10 is effected in its locking position.

FIG. 5 shows an arrangement similar to FIG. 4 with one of FIG. 4 with a drawer 4 placed on the running rail 3 of the drawer guide 1. The drawer 4 has a bottom 14 and side frames 15, 16 and a rear wall 17. The front panel to be provided is not shown in the figure 5, to illustrate the interaction between the pullout guide 1 and the frame 16.

Figure 6 shows a plan view of a detail of Figure 5, after fixing the fasteners by the insertion of the drawer.

As can be seen, projections 18 are provided on the drawer frame 15 instead of the projections 11 on the running rail in this embodiment. Otherwise, the function corresponds to that of the exemplary embodiment of FIG. 3, since the fastening element 10 is also locked or spread open by retraction and / or extension of the drawer 4.

The projection 18a, arranged at the rear of the drawer, is more pronounced in order to press the front fastening element 10b deeper, thus the frame 15 does not drag on the fastening element 10b during retraction and extension of the drawer.

By means of the at least one projection 18, the actuating element 12 of the fastening element 10 is moved axially in order to move the fastening element 10 into its expanded position.

The projection 18 is formed in a particularly simple manner as an expression in a sheet of the drawer frame 16, wherein the projection 18 has a spherical segment-like shape, so that in turn a kind B etätigungs bevel realized. As can be seen from FIG. 7, it is additionally possible to also provide such an inclined surface on the fastening element 12.

It is also conceivable that the projections 18 and the fastening element 10 are positioned or aligned in such different positions that when inserting the drawer, the various fastening elements 10 are actuated in chronological succession.

The drawer can be inserted and assembled by hand. Such assembly is particularly suitable for artisanal businesses. Of course, a machine- or robot-supported - and thus more industrial - assembly is conceivable.

It is essential that the guide rails 2 are first preassembled with the fasteners 10 "loose" on the furniture body 19 and that then by the movement of the drawer 4, a corresponding embodiment of the running rail 2 and / or the drawer 4 per se moving the actuating element 12 - in particular of the fastening element 10 - takes place from the less fixing position into the stronger fixing position.

It is also conceivable to design the projections 11, 18 and the fastening elements in such a way that, in particular when the drawer is placed obliquely, a projection 18a in the direction of insertion initially strikes the rear fastening element 10a when fully pushed onto it and finally fixes it to the body and the front projection 18b ascends or passes over the front anchor only (FIGS. 6 and 11, 12). In this case, the situation may arise that the front projection 18b, which is closer to the front panel, can not yet fully impress the front fastening element 10b due to the small amount of jump. In this installation case, this circumstance is used as a transport lock, the first complete extraction, the fastening element 10b is pressed by the height difference between the projection 18a and the projection 18b. The retraction of the projection 18a onto the fastener 10b may cause the drawer to be kept open, e.g. in slightly opposite to the extension direction inclined Möbelkorpen. It can also serve to lock the drawer in the extended position with self-closing mechanisms that are effective over the entire pull-out path.

Only a subsequent complete first pull-out movement of the drawer 4 (opposite to the direction X in Fig. 6) at the end customer or during assembly also fastened the front fastener 10b completely, since now the rear projection 18a and the front fastener 10b completely.

The lower front projection 18 b of the drawer 4 or the running rail 3 then always has air / clearance to the fastening element 12. The drawer 4 runs smoothly until the rear projection 18a reaches the rear fastener 10a completely in the retracted position.

In this way, a simple tumbler can be designed that prevents unintentional leakage of the drawer 4 without self-closing in not quite upright position or slight vibrations.

Alternatively, it is also possible to place the drawer 4 horizontally on the preassembled guide rail 2 with not yet spread fasteners 10 and then to assemble with only one of the projections 11, 18 during retraction and extension of several of the fasteners 10.

FIGS. 9 to 12 show in addition to the above-considered FIG. Also the furniture body or a furniture body (wall) 19, in which the fasteners 10 engage.
