Description

The present invention relates to a guide device for guiding a sliding door on a running profile in accordance with the restrictive part of paragraph 1 of the claims, as well as to a cabinet furniture product.

The guiding device is known, for example, from patent document EP 0388623 A2, where guiding parts are disclosed with pivotal slide rails or rollers that allow the installation of a sliding door in the lower guide profile after hanging the sliding door in the upper running profile by simply pressing the door into the lower guide profile. Thus, the sliding door is guided in such a way that its deflection in the depth direction relative to the perpendicular to the plane of movement is prevented.

The problem is that when the sliding door is moving to the extreme position determined by the travel stop or damper in the guide profile, if there are no corresponding countermeasures, undesirable oscillations of the sliding door in its vertical plane can occur, since the deviation in the height direction relative to another perpendicular to the plane of movement cannot be prevented sufficiently. The guide part facing the said extreme position can be supported in the vertical direction, while the guide part facing the place at a distance from the said extreme position is counter-displaced and cannot be supported due to lack of contact surface, therefore it does not contribute to the absorption of force .

A known way to prevent this is the additional location of the so-called travel stops in the guide profile. In this case, the guide part facing the travel stop can be moved opposite said travel stop. Since these sliding door guiding parts are not as stable as the running profile and the sliding door chassis moving along it, severe deformation of the guide parts can occur because all the forces generated during a collision are absorbed only by the guide part facing this travel stop.

The present invention is to propose a guide device for guiding the sliding door in the running profile, ensuring the reduction of the above-mentioned oscillation of the sliding door when it is moved to the extreme position without having the above-mentioned travel stop in the guide profile.

This task can be solved by a guide device for guiding the sliding door in a running profile, having the features set forth in claim 1, as well as through a cabinet furniture item having the features set forth in claim 18.

The guide device according to the present invention comprises a guide profile adapted to move a sliding door therethrough, and at least one guide part adapted to be fixed onto the sliding door. The guide profile and said at least one guide part are configured to mate with each other and be able to be guided along the guide profile. In this case, the guide profile and the said at least one guide part are configured to mate with each other with at least a partial geometrical engagement due to the engagement of each other.

This provides, on the one hand, simplifying the installation of the sliding door, since in this case, after hanging the sliding door in the (upper) running profile, it is only necessary to push the door into the (lower) guide profile in the (lower) guide profile area without having to equip the guide device with complex swiveling guiding parts.

The at least partial geometric coupling with the gripping of the guide profile and said at least one guide part also ensures that, in the presence of forces acting in the vertical direction and resulting from the sudden braking of the sliding door as it moves to the extreme position, the said forces are distributed along the length of the guide part in the direction of the longitudinal axis of the guide profile in the case of a single guide part mated with the guide profile in such a way that ascheno point force to the guide portion.

The guide device preferably comprises two guide portions that are located as far as possible from each other, since this ensures a particularly effective resistance to forces acting, in particular, in the vertical direction. Resistance to vertical forces by means of only one guide part is far from being so effective even if this part has a relatively large width.

The proposed guide device can also be made with one or more than two guide parts.

Preferred embodiments of the present invention are the objects of the dependent claims.

In accordance with a preferred embodiment of the present invention, the guide portion comprises a main corner portion and a head portion adapted to mate with a guide profile.

In accordance with a preferred embodiment of the present invention, the guide part is made as one unit. In accordance with another preferred embodiment of the present invention, the guide part is made of several parts, in particular two parts. The main corner portion is preferably made of a material different from the material of the head portion. For example, the main corner portion can be made of metal and be attached to a sliding door, for example, by bolting.

According to a particularly preferred embodiment of the present invention, the head portion and the guide profile are made of different plastic materials. The manufacture of these parts from plastic materials is permissible due to the wide distribution of forces acting during braking. The advantages here are not only in economically profitable production, but also in the ease of interfacing with each other and disengaging the guide profile and the at least one guide part.

In the manufacture of the head part of the guide part from the first plastic material, and the guide profile from the second plastic material, the formation of interfering noises is prevented when these parts slide against each other during the movement of the sliding door.

The head part is preferably made with the possibility of attachment to the main corner part of the guide part with friction, geometric and / or cohesive coupling.

As mentioned above, in order to ensure the effective distribution of forces during the deceleration of a sliding door, only one guide part of a certain width can be installed on it.

In a preferred embodiment of the present invention, the guide device comprises two guide portions that are adapted to be fixed to the sliding door and which, when mounted, are associated with the guide profile and are spaced apart from each other on the sliding door, as a result of which the sliding door is braked parts perceives forces acting vertically downwards, while the other guide part perceives forces acting vertically upwards, which Essentially prevents the swing door from vibrating.

According to a preferred embodiment of the present invention, the head part of the guide part comprises a receiving groove with a hole between the elastically deformable legs of the groove, said hole facing the guide profile. This receiving groove is adapted to accommodate the head element of the guide profile, the head element of the guide profile having a cross section perpendicular to the longitudinal axis of the guide profile, the maximum width of which in the vertical direction is greater than the width of the opening of the receiving groove of the guide part.

In an alternative embodiment of the present invention, the receiving groove is a part of the guide profile with elastically deformable legs of the groove, adapted to accommodate the head element of the guide part. The maximum width in the vertical direction of the cross section of this head element, perpendicular to the longitudinal axis of the guide profile, is greater than the width in the vertical direction of the opening of the receiving groove of the guide profile.

The mating unit is designed so that it is possible to simply mate the guide profile with said at least one guide part without using a hinge, necessary in accordance with the prior art to ensure the connection of the guide profile after mounting the sliding door in the running profile.

The cross-sectional shape of the head part of the guide profile or the head part of the guide part can be chosen arbitrarily, since an undercut is made in the guide profile, forming a tooth in a certain sense, preventing unintended separation. In a preferred embodiment, this cross section has a trapezoidal, substantially round or oval shape.

According to an alternative embodiment of the present invention, the cross section of the head of the guide profile or the head of the guide part is made tapering in the direction of the receiving groove of the guide part or the receiving groove of the guide profile.

According to a particularly preferred embodiment of the present invention, the angle between the converging first side surfaces of the head element of the guide profile or the head part of the guide part is from 50 ° to 100 °, preferably from 60 ° to 80 °, which makes it easy to insert the head part or head element into the receiver. groove.

The angle between the converging second side surfaces on the side of the head element of the guide profile that faces the leg or on that side of the head part of the guide part that faces the main corner part is preferably from 120 ° to 170 °, more preferably from 140 ° to 160 °, which provides the possibility of dismantling the guide part from the guide profile with the expenditure of greater effort than during installation of the installation, and reliably prevents unintentional disassembly.

To ensure the comparative ease of mating and the difficulty of separating the guide parts and the guide profile, the planes of the front sides of the head element of the guide profile or the head part of the guide part extend more hollowly than the rear planes.

The receiving groove on the guide part or the guide profile, configured to accommodate the head element or the head part, is made essentially C-shaped to facilitate the function of said undercut. In this case, the receiving groove preferably has such a C-shape that its plane of symmetry is horizontal.

At least a partial geometric clutch with the grabbing in the mounted position of the guide part and the guide profile does not necessarily mean that these parts are in contact when moving the sliding door beyond the extreme position. On the contrary, the contact of the respective contact surfaces takes place when the sliding door reaches the corresponding end position.

Cabinet furniture product according to the present invention is characterized by the presence of the above-described guide device located on the sliding door as described above.

In accordance with a preferred embodiment of the present invention, the guide profile is adapted to be fastened to a plank at the base or the base of a cabinet furniture item.

In an alternative embodiment of the present invention, the guide profile comprising at least one receiving groove is made in one piece with the bar at the base or the base of the cabinet furniture item.

The guide device can also be installed in the upper part of the sliding door or on the top panel of a cabinet furniture product, and the running profile with the running device is in the lower part of the door and / or on the bottom or bottom panel, that is, in a certain sense, with changing positions .

The fastening leg 61, 81 is preferably flat and has a surface supported on the inner side of the sliding door 2, 3, in which holes are preferably made through which screws can be inserted, by means of which the guide part 6, 8 can be screwed to the sliding door 2, 3. Other mounting options can also be applied, for example, by means of a clip or a U-shaped fastening leg covering the bottom edge of the sliding door.

As shown in FIG. 5 and 6, the leg 62, 82 can also be made flat. It is also possible to design the legs 62, 82 in the form of a plurality of bridges parallel to each other, connecting the head part 63, 83 with the main corner part 61, 81, as shown in FIG. 2

The guide profile 5, 7 and the said at least one guide part 6, 8 (in the shown embodiments, the two guide parts 6, 8) are designed so that they can be joined with each other when the sliding door 2, 3 is mounted after as a sliding door 2, 3 was suspended in the upper running profile 15, while providing the possibility of guiding the sliding door along the guide profile 5, 7.

As shown in FIG. 3a, 3b, 4a and 4b, the guide profile 5, 7 and the said at least one guide part 6, 8 can be mated with each other in a direction perpendicular to the longitudinal axis of the guide profile, with at least partial geometric engagement due to the engagement another, which ensures that the sliding door along with the guide part can be simply pressed into the guide profile after mounting on the upper running profile 15. In the embodiment shown in FIG. 3a, 3b and 7, the head portion 63 of the guide part 6 comprises a receiving groove 65 for receiving the head element 53 of the guide profile 5.

The receiving groove 65 has an opening 66 facing the guide profile 5. At the same time, the groove 65 is formed by essentially two elastically deformable legs 64 of the groove, between which free ends there is formed an opening 66.

The head element 53 of the guide profile 5 has a cross section perpendicular to the longitudinal axis of the guide profile 5, the maximum width b _{K of} which in the vertical direction is greater than the width b _{O of the} opening 66 of the receiving groove 65 of the guide part 6.

The head element 53 of the guide profile 5 is made in the form of the free end of the leg 52 of the guide profile 5 extending from the main element 51.

The number of head elements 53 of the guide profile 5 (in the shown embodiment, two head elements 53 are contained) depends, among other things, on the number of sliding doors 2, 3 guided in the guide profile 5.

In an alternative embodiment shown in FIG. 4a and 4b, the receiving groove 72 is a part of the guide rail 7.

In this case, the head part 83 of the guide part 8 has in the direction perpendicular to the longitudinal axis of the guide profile 7 a cross section, the maximum width b _{K of} which in the vertical direction is greater than the width b _O facing the guide part 8 of the hole 75 of the groove 72 of the guide profile 7. the receiving groove 72 is equipped with two elastically deformable legs 73 of the groove extending from the main part 71 of the guide profile 7 to the guide part 8.

As shown in FIG. 4a and 4b, a neck 84 is formed between the head part 83 and the leg 82 of the guide part 8, the width of which is in the vertical direction less than the width b _O in the vertical direction of the opening 75 of the receiving groove 72.

In addition, the leg 82 can be made tapering in the direction from the mounting foot 81 to the head part 83 so that the area immediately behind the head part 83 is narrowed accordingly.

In this embodiment of the present invention, the cross section of the head element 53 of the guide profile 5 or the head part 83 of the guide part 8 has a trapezoidal shape, but it can have any other shape, in particular, essentially round or oval. The only thing that is essential is the presence of an undercut, which forms a prong, which prevents inadvertent separation.

Alternatively, the cross section of the head element 53 of the guide profile 5 or the head part 83 of the guide part can be made 8 tapering in the direction of the receiving groove 65 of the guide part 6 or the receiving groove 72 of the guide profile 7, as shown in FIG. 2-8.

As shown in FIG. 7 and 8, the angle a between the converging first side surfaces 531, 831 of the head element 53 of the guide profile 5 or the head part 83 of the guide part 8 is from 50 ° to 100 °, preferably from 60 ° to 80 °, to allow the release of the guide profile 5 , 7 and the guide part 6, 8 with the application of a small force. Thus, the entry of the head element 53 or the head part 83 into the receiving groove can be made at an acute angle α.

The rear side of the head element 53 or the head part 83, directed before mounting in the direction opposite to the receiving groove 65, 72, is made so that the angle β between the converging second side surfaces 532, 832 on that side of the head element 53 of the guide profile 5, which faces The leg 52, or on that side of the head part 83 of the guide part 8, which faces the main corner part, ranges from 120 ° to 170 °, preferably ranges from 140 ° to 160 °, and thus forms an obtuse angle.

Angle γ, ranging from 120 ° to 170 °, preferably from 140 ° to 160 °, is formed on the legs 68, 78 of the guide part 6 or the guide profile 7 to help effectively prevent separation.

Preferably, the angles α and γ are chosen so that they have approximately the same magnitude.

Thus, it is ensured that to separate the parts from each other it is necessary to expend more effort than to pair them.

In one embodiment, for example, in the embodiment shown in FIG. 3a, 3b, 4a and 4b, the guide part 6, 8 can be made as a single piece, with the head part 63 in which the receiving groove 65 is formed in the free end of the leg 62.

The same applies to the head element 83 of the guide part 8, made with the possibility of entering into the receiving groove 72 of the guide profile 7.

In an alternative embodiment shown in FIG. 5 and 6, the guide part 6, 8 is made of several, in particular, two parts.

In this case, the fastening of the head part 63, 83 to the main corner part of the guide part 6, 8 is preferably carried out so that the end of the head part 63, 83, which faces the mounting leg 61, 81, contains a receiving groove 69, 89 located between the legs 67, 87 and configured to accommodate the leg 62, 82 of the main corner portion. In this case, the fastening is provided by frictional, geometrical and / or cohesive coupling, preferably by gluing and / or clamping.

While the main corner part of the guide part 6, 8 can also be made in the form of a wire molded part.

Said at least one head part 63, 83 of the guide part 6, 8 is preferably made of an elastic plastic material.

In case the head part 63, 83 of the guide part 6, 8 and the head part 63, 83 of the guide profile 5, 7 are made of plastic material, the head part 63, 83 of the guide part 6, 8 and the head part 63, 83 of the guide profile 5, 7 are made of different plastic materials to prevent the formation of unwanted noise when these parts slide against each other.

The guide profile 5, 7 is preferably fixed to the base 14 of the cabinet furniture item 1, for example, by screwing with a screw 9 or fastening with a clamp.

In the embodiment, in which the guide profile 7 has at least one receiving groove 72, the guide profile 7 can also be made in one piece with the panel at the base or base 14 of the housing furniture item 1.
