DESCRIPTION

Rolling mechanism for a sliding door or a folding sliding door

The present invention relates to a rolling mechanism for a sliding door or a folding sliding door, composed of a rolling mechanism box that can be fixed on the side of the door and by a support of the rolling mechanism attached thereto. , which at its free end distant from the case of the rolling mechanism is equipped with parts of the rolling mechanism in the form of pulleys and / or skates.

10 Rolling mechanisms of the aforementioned genre are known in multiple embodiments and serve to suspend sliding doors or folding sliding doors on a guide rail on the side of the furniture body and guide them movable along this guide rail.

The known rolling mechanisms are relatively complicated and are made up of many

15 individual parts and require a high assembly cost. In the known rolling mechanisms the rolling mechanism housing is configured in the form of a circular disc cut on one side and can be inserted into a corresponding recess of a door leaf.

If sliding doors or folding sliding doors are used that have a continuous frame composed of profiles

20 gaps, at least in the mounting area of known rolling mechanisms, hollow profiles of relatively large dimensions have to be used, in order to accommodate the rolling mechanism housing of known rolling mechanisms.

US 2002/0138493 and US 2001/0003855 disclose examples of rolling mechanisms for a sliding door or a folding sliding door.

The problem of providing a rolling mechanism of the indicated genre, which is distinguished both by a simple construction and by an easy mounting possibility, and which in particular is appropriate to be used even in comparatively narrow hollow profiles, serves as a basis for the present invention. of a door frame and that in addition to

30 This can also be used on elements of sliding doors made of wood, glass or plastic.

This problem is solved according to the invention because the casing of the rolling mechanism is composed of an elongate base body approximately in the form of a parallelepiped with a support flange partially protruding from this base body and because on two mutually opposite front sides of the body base pins are provided

35 elastic interlocking with shaped interlocking cams, so that the rolling mechanism housing can be inserted with spring closure into an oblong-shaped neckline on the side of the door.

A rolling mechanism according to the invention is distinguished by its elongated base body that deviates from the circular shape, which makes it possible to fix the rolling mechanism even in frame profiles that are comparatively

40 thin dimensions. In addition to this the fixing of the rolling mechanism according to the invention is carried out very simply, since for the purpose of mounting the rolling mechanism it is only necessary to spring-close the rolling mechanism housing with its two locking pins in a neckline in the form of an oblong hole of a sliding door or in a recess of a mounting plate or of a hollow frame profile.

45 If necessary, the rolling mechanism can also be removed again from the sliding door or folding sliding door, since for this purpose only the two interlocking pins have to be compressed, until the interlocking is canceled with respect to the plate Mounting or hollow frame profile.

It is not necessary to fix the rolling mechanism by additional screwing or other fastening means.

50 Therefore, the rolling mechanism can be mounted or, if necessary, disassembled without tools on a sliding door or a folding sliding door.

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

In Figure 1 it is - as in other Figures - designated in conjunction with the reference sign 1 a rolling mechanism for a sliding door or a folding sliding door 2 shown briefly in Figure 2.

The rolling mechanism 1 can be mounted, for example, directly on the sliding door or folding sliding door 2 or - alternatively thereto - in a hollow frame profile 3, as shown in Figure 3. As in particular the Figures clearly show 7a to 7c, the rolling mechanism 1 is essentially composed of three construction groups. Figure 7a shows a box 4 of the rolling mechanism, which is determined for fixing the rolling mechanism 1 together in a sliding door or a folding sliding door 2 or in a hollow frame profile 3. With this box 4 of the Rolling mechanism is attached a support 5 of the rolling mechanism, as shown in Figure 7b.

The joint, which also allows a height adjustment of the support 5 of the rolling mechanism with a spindle to the case 4 of the rolling mechanism, is carried out by means of a knurled nut 6, as shown in Figure 7c.

The support 5 of the rolling mechanism is equipped with parts of the rolling mechanism, in the exemplary embodiment shown with pulleys 7. Alternatively, however, the support 5 of the rolling mechanism can also be equipped with skates or with a combination of skates and pulleys 7.

The support 5 of the rolling mechanism has an approximately T-shaped configuration, the central branch 5a being equipped with thread 5b and on two diametrically opposite sides equipped with flattening 5c. This results in a non-round cross-sectional shape, this cross-sectional shape being identical to the cross-sectional shape of a housing opening 4a within the housing 4 of the rolling mechanism. In this housing opening 4a, the central branch 5a of the bearing mechanism 5a can be inserted against rotation.

Approximately in the central area of the housing 4 of the rolling mechanism, a housing groove 4b is clearly provided with respect to the housing opening 4a, into which said knurled nut 6 is inserted. This knurled nut 6 surrounds the thread 5b of the central branch 5a and therefore allows, on the one hand, the fixing of the support 5 of the complete rolling mechanism with respect to the housing 4 of the rolling mechanism as well as on the other hand a height adjustment of the support 5 of the rolling mechanism with respect to the case 4 of the rolling mechanism.

The mentioned construction groups integrating the rolling mechanism 1 can therefore be joined together without the help of additional tools.

This results in a simple and easily realizable assembly of the rolling mechanism 1 as a whole.

The case 4 of the rolling mechanism as well as the support 5 of the rolling mechanism is made of plastic.

Knurled nut 6 can also be made of plastic, but for stability reasons a knurled nut 6 of metal is preferred here.

On one side of the central branch 5a provided with a flattening 5c, in the middle to lower area of this central branch 5a there is formed an interlocking shoulder 5d in the form of a sawtooth. In the upper end area of the thread 5b on the opposite side, also provided with a flattening 5c, an end stop 5e is placed.

This results in particular from Figure 10.

In the upper end area of the housing opening 4a of the case 4 of the rolling mechanism, mutually opposite projections 4c are also provided in the form of a sawtooth. One of these projections 4c corresponds to the interlocking projection 5d of the central branch 5a. This means that when the central branch 5a is introduced into the introduction opening 4a, the locking projection 5d provided in the central branch 5a passes over one of the two projections 4c of the housing 4 of the rolling mechanism due to the given elasticity. On the contrary, an extraction is no longer possible immediately after the support 5 of the rolling mechanism outside the insertion opening 4a of the housing 4 of the rolling mechanism, since in this direction the interlocking shoulder 5d and one of the projections 4c They act as blocking means.

Said stop 5e in the upper area of the central branch 5a, on the contrary, prevents any deep introduction of the support 5 of the rolling mechanism into the housing 4 of the rolling mechanism. Between the two limits of the interlocking shoulder 5d and the stop 5e the support 5 of the rolling mechanism is height adjustable with respect to the housing 4 of the rolling mechanism.

This height adjustment is carried out by actuating knurled nut 6.

As shown in particular in Figure 9, the upper transverse branch 5f of the bearing 5 of the rolling mechanism in its two front end zones is equipped with a part with wave-shaped end sections 5g, elastic in the rolling direction, as well as with tabs 5h located above, elastic perpendicular to the direction of travel. On its significance it goes into detail below.

The housing 4 of the rolling mechanism essentially comprises a base body 4d approximately in the form of a parallelepiped as well as a support flange 4e partially protruding from this base body 4d.

The base body 4d on its two opposite front sides is equipped with elastic interlocking pins 4f with shaped interlocking cams 4g.

As shown in particular in Figure 6, the elastic interlocking pins 4f with the shaped interlocking cams 4g serve to fix by spring closing the housing 4 of the rolling mechanism for example in a mounting plate 8 with a neck 8a in shape of oblong hole or within a recess 3a in the form of oblong hole of the hollow frame profile shown in Figure 3 or in a recess 3a, 8a in the form of oblong hole practiced directly on the sliding glass door element.

Due to the elastic capacity of the pins 4f, disassembly can also be carried out by compressing the two elastic pins 4f to the point that the grip behind the mounting plate 8 or a wall of a hollow frame profile 3 is canceled. In this compressed position of the elastic pins 4f, the box 4 of the rolling mechanism of the corresponding support pieces (mounting plate 8 or hollow frame profile 3) can then be removed.

If the rolling mechanism 1 is held directly on a sliding door or a folding sliding door 2, as in Figure 2 and in Figure 5 it is indicated by way of example, a milling 2a is provided in this door 2 , into which the base body 4d of the rolling case 4 can penetrate. Such a mounting possibility results both in wooden doors and in plastic doors, an adequate possibility of mounting in glass doors is conceivable, in the latter case being the mounting plate 8 preferably glued to a glass plate. However, it is also conceivable - as already mentioned above - to directly practice a corresponding recess 3a in the form of an oblong hole in a sliding door element composed of a glass or plastic plate.

Figures 13 to 15 show that on a guide rail 9 for housing the upper transverse branch 5f of the bearing 5 of the rolling mechanism a final stop 10 is placed, which on the one hand is equipped with a stop block 10a and by another part with a retention tab 10b, which is elastic perpendicular to the direction of travel of the rolling mechanism 1. The end stop 10 is fixedly mounted on the guide rail 9.

The stop block 10a serves as a final limitation for the travel path of a sliding door or a folding sliding door, this stop block 10 being located in the travel path of the end areas 5g of the support 5 of the rolling mechanism, elastic in the direction of travel. By means of this elastic configuration of the end zones 5g, a damping in the scope of the final position is ensured. The retention tab 10b of the end stop 10 cooperates with the tabs 5h of the bearing 5 of the rolling mechanism, also elastic perpendicular to the direction of travel. The retention tongue 10b is adapted in terms of its contour to the contour of the elastic tongues 5h and with a sliding door or folding sliding door 2 closed, the retention tongue 10b rests under a certain shape closure on one of the elastic tongues 5h of the 5 support of the rolling mechanism. This results in a relatively safe closing maintenance of the sliding door or folding sliding door 2 in the closed position. When you open again you must overcome small forces of

image7

5 friction between the tabs 5h and the retaining tab 10b of the end stop, but these friction forces are relatively small, so that no excessive force is required here to open a sliding door or a folding sliding door 2 from the closed position

The rolling mechanism 1 according to the invention consists of a total of fewer individual parts, it is easy to assemble in

10 set and also easy to hold on a sliding door or a folding sliding door 2. This is also valid when a similar door is equipped with a frame consisting of hollow profiles. Also, the mounting of the rolling mechanism on a sliding door or a folding sliding door is simply achievable and finally you do not need any tools.
