Description

<Desc / Clms Page number 1>
The present invention relates to a sliding door guide with a movement and support rail and a guide rail, rolling and support rollers being fixed to a sliding door leaf on the one hand, which - by carrying the leaf sliding door - engage in the movement and support rail and, with guide rollers being fixed to the sliding door leaf on the other hand, which - by guiding the door leaf and securing it against lateral tilting - s 'engage in the guide rail which has a U-shaped section in the receiving area of the guide rollers.

Sliding door guides of the generic type are known in the most varied embodiments.

Regardless of the variety of sliding door guides - for example, the travel and support rails and guide rails can be plastic, metal, or plastic-coated metal, or the movement and support rollers support and guide rollers can be produced in a wide variety of materials. All these sliding door guides are based on a common construction principle. This common construction principle provides that the movement and support rollers engage in the movement and support rail in a rotatable manner about a horizontal axis and by carrying the sliding door leaf, while the guide rollers '' engage in the guide rail rotatably around a vertical axis and securing the sliding door leaf against lateral tilting.

In general, the movement and guide rail is placed in the upper part of the sliding door leaf and the guide rail accordingly in the lower part of the sliding door leaf. But a reversal of this arrangement is naturally conceivable, namely with the guide rail in the upper part and the movement and support rail in the lower part of the sliding door leaf.

In all cases, when hanging a sliding door in the movement and support rail on the one hand, as well as in the guide rail on the other hand, it was hitherto necessary to place d first the guide rollers in the engagement area of the guide rail and then raise or lower the entire sliding door leaf in the vertical direction until the movement and support rollers come into contact taken with the displacement and support rail.

<Desc / Clms Page number 2>

 This requires a certain address - on the one hand, and a significant force on the other hand in the case where the sliding door leaf is relatively bulky and relatively heavy.

The objective of the present invention is therefore to create a sliding door guide of the generic type which allows a simplified and easy to perform mounting of a sliding door leaf.

A first solution to this objective provides that the lateral branch of the functional U-shaped part of the guide rail which faces the sliding door leaf is provided with at least one recess whose size corresponds at least to the size of a guide roller, so that at least one guide roller can be folded into the guide rail transversely thereto. A second solution of the objective of the present invention resides in the fact that the lateral branch of the functional U-shaped part of the guide rail which faces the sliding door leaf is shaped divided in the longitudinal direction, so that a lower branch section laterally covering the guide rollers in the service position can be moved relative to the remainder of the branch section of the guide rail until the guide rollers can be folded down without hindrance in the guide rail guide.

The two solution proposals have in common the measure consisting in designing the guide rail in such a way that the guide rollers can be folded laterally at the level of the guide rail, which has the advantage that, when mounting a leaf sliding door, we first hook a movement and support roller in the movement and support rail and, thus, the entire weight of the sliding door leaf can be supported at least by the movement and support rail, and that, under these facilitated conditions, the guide rollers can then be folded laterally at the level of the guide rail.

In the first cited solution of the objective underlying the present invention, an advantageous variant resides in the fact that the guide rail is provided with recesses corresponding to the number of guide rollers and spaced from one another by the same distance than the guide rollers.

In this case - as in the second solution mentioned, too - a sliding door leaf can first be completely hooked into the movement and support rail, then the rollers.

 guide can be folded into the active area of the guide rail.

Other features of the invention are the subject of other dependent claims.

The attached drawings show examples of embodiments of the invention which are described in detail in the following.

Are shown in Figure 1: a perspective view of a cabinet with a sliding door guide according to the present invention, in a first mounting position of a sliding door leaf, Figure 2: a side view of the cabinet and the leaf sliding door according to the mounting position of Figure 1, Figure 3: a view corresponding to Figure 2 with the sliding door leaf permanently mounted, Figure 4: a partial view of a guide rail with recesses can be closed by plugged-in elements, FIG. 5: a partial section along the line VV of FIG. 4, FIG. 6: a partial view corresponding essentially to FIG. 4, of a guide rail provided with a recess and elements of pivoting closure, Figure 7: a vertical section of a guide rail with recesses and folding elements to close the recesses, Figure 8: a perspective view of a guide rail with recesses and with grout buckets to close these recesses, Figure 9: a vertical section of the guide rail area of a piece of furniture equipped with two sliding door leaves, Figure 10: a perspective view of a guide rail with divided guide branches in the longitudinal direction.

In FIGS. 1 to 3 is generally identified by the reference 1 a piece of furniture which is equipped with at least one sliding door leaf 2.

The sliding door leaf 2 is coupled with respect to the furniture body identified by the reference 3 by a sliding door guide which consists of a movement and support rail 4, a guide rail 5, rollers of displacement and support 6 and guide rollers 7.

The movement and support rail 4 is mounted on the furniture body 3, like the guide rail 5.

The displacement and support rollers 6 are fixed to the sliding door leaf 2, as are the guide rollers 7.

<Desc / Clms Page number 4>

 In the embodiment shown in Figures 1 to 3, the guide rail 5 is provided with two functional U-shaped zones 8, in which engage the guide rollers 7, which can rotate around vertical axes, two sliding door leaves 2. For the sake of clarity, only one sliding door wing 2 is shown in FIGS. 1 to 3.

The lateral branches 9 of the guide rail 5 facing the sliding door leaf 2 are provided with recesses 10 whose size corresponds at least to the size of a guide roller 7.

Beyond the example of embodiment shown, said lateral branches 9 of the guide rail 5 can also be provided with a number of recesses 10 corresponding to the number of guide rollers 7, which then have the same distance between them as the guide rollers 7 on the sliding door leaf 2.

In both cases, there are the following possibilities for mounting the sliding door leaf 2 First, a displacement and support roller is hooked into the displacement and support rail 4 of the sliding door guide. The guide rollers 7 are still outside the guide rail 5. In this position, the weight of the sliding door leaf 2 is still almost completely supported by the movement and support rail 4. An assembler can then, without having to support the weight of the sliding door leaf 2 itself, move the sliding door leaf 2 until a guide roller 7 is at a recess 10. It is possible to pivot the door leaf sliding door 2 laterally until the guide roller 7 located opposite the recess 10 has entered the functional area 8 of the guide rail 5. The sliding door leaf 2 is then moved until the second guide roller 7 is located at a recess 10, and this connecting roller can then be retracted into the functional area 8 of the guide rail 5. If the guide rail is provided with a number of recesses 10 corresponding to the number of guide rollers 7, at the start of assembly, all the movement and support rollers 6 can be hooked into the movement and support rail 4, then simply move the sliding door leaf until the rollers displacement 7 and the recesses 10 are opposite, so as to then return these displacement rollers 7 into the functional area 8 of the guide rail 5.

 For safety reasons, it is advantageous to close the recesses 10 after mounting the sliding door leaf 2.

As shown in FIGS. 4 and 5, this can be done with simple plug-in elements 11, which can be pushed into the lateral branch 9 of the guide rail 5 by covering the recess 10.

FIG. 6 shows a possibility of covering the recesses 10 by pivoting tabs 12 pivotally attached to the lateral branches 9 of the guide rail 5.

FIG. 7 shows a possibility of covering the recesses 10 by folding elements 13 which can be connected to the guide rail 5 and can be pivoted around a film hinge 14 in a closed and open position.

FIG. 8 shows a variant in which sliders 15 are provided, at the level of the recesses 10, which can be moved along the guide rail 5 in order to close the recesses 10 after the assembly of a sliding door leaf 2.

As clearly shown in FIG. 9, the sliders 15 are provided here with control buttons 16 which facilitate the opening or closing of the recesses 10 by longitudinal displacement of the sliders 15.

FIG. 10 shows a guide rail 5 of a sliding door guide in which the branch 9 of the guide rail 5 facing the sliding door leaf 2 is divided in the longitudinal direction. A lower branch section 17 laterally covering the guide rollers 7 in the service position is then movable relative to the rest of the branch section 18 until the guide rollers can be folded down without hindrance in the guide rail 5.

In the construction of the present invention of FIG. 10, before the mounting of a sliding door leaf 2, the guide rail 5 is adjusted so that the lower branch sections 17 of the side branches 9 are moved as far as possible towards the high. The sliding door leaf 2 can then be suspended with its movement and support rollers 6 in a movement and support rail 4, then the sliding door leaf 2 can be folded down on a piece of furniture 3 so that the guide rollers 7 are located in the functional area of the guide rails. The lower branch sections 17 are then moved downwards until the guide rollers 7 are covered and cannot

<Desc / Clms Page number 6>

 therefore no longer be removed from the cabinet 3.

Concerning the production of the lateral branches 9 separated in the longitudinal direction and movable, other embodiments are naturally conceivable. In the embodiment of FIG. 10, these lower branches sections 17 are shaped into U-shaped sections, which are pressed onto the upper branches sections 8 by gripping them. As a variant, each lower branch section 17 may also be made of simple flat material and be connected, by lug guides and groove relative to the upper branch section 18, with the latter.
