Description

The present invention relates to accessories for a sliding door containing a rail along which at least one running element is disposed, with the possibility of displacement, and an automatic removal device with a driving element moving along the guide track, mating with a driving element located on the running element for moving the running element to end position.

DE 202009014882 discloses accessories for a sliding door in which a driving element is located on the running element, which is interfaced with a closing device. The drive element in this case can be fixed on a roller carrier. This allows you to do without the use of tools when installing drive elements on a roller carrier.

DE 102011050394 describes fittings for a sliding door in which there is a drive element on the running element which is adapted to engage with the automatic retraction device. The drive element is held on the running element with the possibility of adjustment, so that it is possible to easily compensate for the tolerance. However, a chassis requires many components. In addition to this, apart from the drive element, a sliding guard is also usually installed on the sliding door hardware to prevent the sliding door from unintentionally leaving the rail. Therefore, when installing accessories for a sliding door, it is necessary to install and align many different parts, in particular, if the right and left running elements are used in the sliding door.

Thus, the task of the invention is to create accessories for a sliding door, which has a simple structure and provide easy installation.

The specified problem is solved in the accessories having the features according to paragraph 1 of the claims of the present invention.

According to the invention, the drive element is arranged to move relative to the carrier of the running element from the mounting position to at least one functional position in which it is possible to interface with the driving element of the automatic retraction device, the drive element making it possible, in the mounting position, to mount the running element on the guide, in the functional position, protects the running element from exiting the rail by means of an emphasis on the drive element. Thus, the anti-popup fuse is implemented by a drive member that prevents the running member from flying out of the rail, at least to the extent that the running member can be removed from the rail. In addition to the anti-pop-up safety function, the drive element is configured to mate, in a functional position, with an automatic retraction device that moves, by the drive element, the sliding door to a predetermined end position. The automatic lead-off device can, in this case, by means of a spring, create a preliminary load on the driving element in the direction of the end position, and optionally, a damper can be provided on the automatic take-off device. Thus, accessories for a sliding door can have a high level of functionality with a small number of parts.

Preferably, the drive element is pivotally mounted on the carrier of the running element. Alternatively, the drive element may be biasedly mounted on the carrier of the running element so that movement from the mounting position to the functional position or in the opposite direction can be made. In this case, each of the rotation and / or displacement movements can be carried out without using a tool. In addition to the option of fastening the drive element to the sliding door already before installation, with subsequent long-term leaving there both during installation and during the removal of a piece of furniture with a sliding door, this is an important advantage.

In one embodiment of the invention, the drive element comprises a protrusion configured to engage with a socket on a driving member of the automatic retraction device. The protrusion can be protruded essentially perpendicularly in one direction from the carrier element made in the form of a plate of the carrier, thereby obtaining a compact structure. In addition, the protrusion can be positioned at a distance from the stop to protect against exiting the rail.

For ease of manufacture of accessories with a small number of parts, the drive element can be made integral, in particular, from plastic or metal. Especially preferred are composites of soft plastic components, for example, composites of plastic and rubber (composites of type K & K). The drive element can also be fixed in the mounting position and / or functional position, to prevent inadvertent release after moving the drive element to the functional position. The fixation can be carried out by means of functional elements of the power and / or geometric closure, formed indirectly or directly on the drive element and the running element.

Preferably, the drive element is movable from the mounting position to two different functional positions. This allows you to refuse to use the left and right running elements, that is, running elements mounted on the left or right side of the sliding door. Two running elements that are identical in design can be mounted on the right and left sides of the sliding door, so that this element is right or left is determined only by moving the drive element to the corresponding functional position. This allows you to reduce the cost of storage and simplify installation.

To provide particularly high damping forces on the running element, two drive elements can be positioned, each of which interacts with an automatic retraction device. In this case, the automatic retraction device may comprise a damper so that the fittings according to the invention can also be used when moving very heavy sliding doors. Alternatively, an opening damper may be driven by a first drive element and a cover damper by a second drive element. In this case, this group of drive elements and dampers can be located both in one plane and in different planes. It is also possible to have more than two drive elements, automatic retraction devices or dampers.

The invention is described in more detail below with reference to several embodiments and with reference to the accompanying drawings, in which the following is depicted.

In FIG. 1 shows a perspective view of a piece of furniture with the proposed accessories for a sliding door.

In FIG. 2 is a side view of the piece of furniture of FIG. one.

In FIG. 3 is a side view of the piece of furniture of FIG. 1 in a modified embodiment.

Figures 4A and 4B show two types of fittings from FIG. 2 with different positions of the drive element.

Figures 5A-5C depict a plurality of types of fittings of FIG. 2.

Figures 6A-6D depict a plurality of types of fittings of FIG. 5.

Figures 7A and 7B show two types of fittings of FIG. 5 in a modified embodiment.

In figures 8A-8C depict types of fittings in a modified embodiment.

Figures 9A-9D show hardware views in another embodiment.

Cabinet 1 contains a furniture case 2, on which a rail 3 is fixed for installation, with the possibility of displacement, of a group of running elements 4 of accessories for a sliding door. The running elements 4 can interact in the final position with the automatic retraction device 5 to bring the sliding door to its final position. In addition, the automatic retraction device 5 may provide appropriate damping in the opening or closing direction.

In FIG. 2 hardware is shown in side view. The rail 3 is fixed by means of the upper horizontal shelf 30 on the upper panel 20 of the furniture case 2. On the rail 3 two U-shaped running tracks 31 and 32 are formed for the rollers 9. Naturally, variants are also possible in which the rail 3 contains only one running track or more two running tracks for guiding the rollers 9.

The automatic removal device 5 includes a casing 6, fixed on the rail 3 of the furniture case 2. On the casing 6 there is a movable leading element 7, made with the possibility of displacement along the guide track and transmitting the corresponding opening, closing and / or damping forces to the drive element 8, fixed on the running element 4. The running element 4 is fixed in this case behind the front plate 60 of the sliding door, and for each front plate 60 there are two spaced apart running elements 4. To and t he position of the running elements 4 can be selected depending on the weight of the front plate 60.

FIG. 3 shows a modified embodiment of a hardware in which, in addition to the example of FIG. 2, an additional automatic retraction device 5 'is provided, comprising a casing 6' on which the driving member 7 'is mounted, with the possibility of bias. In turn, the driving element 7 'can move along the guide track and be pre-loaded by means of a spring in the direction of the initial position. In addition, a damper may be located on the automatic lead-off device 5 ′ to enable braking or acceleration of the front plate 60 by the running member 5 by means of two automatic lead-off devices 5 and 5 ′. This makes it possible to obtain an increase in the diverting force or damping force, in particular in the case of heavy front plates 60.

In FIG. 4A depicts the fittings of FIG. 2 in the mounting position. The drive element 8 includes a protrusion 80, essentially perpendicular to the protruding from the plane of the front plate 60, and in the mounting position, the drive element is aligned in the downward direction. In this case, the drive element 8 is mounted to rotate about the axis 83, and in the mounting position between the upper surface 84 and the lower side of the rail 3 there is a gap L, which allows you to remove the running element 4 with the front plate 60. The gap L in this case is greater than a vertical portion of the side wall 33 defining the track 32. Thus, the roller 9 can be removed from the track 32 by lifting the front plate 60 and moved over the side wall 33 to remove the front plate 60.

In FIG. 4A depicts the fittings of FIG. 4B in the functional position. The drive element 8 is rotated approximately 90 °, so that the protrusion 80 is already located not under the axis 83, but essentially at the same height with it. In this position, as shown in FIG. 2, the protrusion 80 of the drive element 8 may engage with the driving element 7 of the automatic retraction device. In this case, by turning the drive element 8 under the rail 3, a stop 85 is installed, which is closer to the rail 3 than the surface 84. As a result, a gap 88 is obtained between the lower side of the track 32 and the stop 85, which is less than the height of the side wall 33 on the rail 3, and therefore less than the gap L. Thereby, it is possible to avoid raising the front plate 60, in which case the roller 9 could exit through the side wall 33, therefore, the emphasis 85 is used as a guard against popping up.

Figures 5A-5C depict in detail the running element 4 of the hardware of FIG. 2. The running element 4 comprises a plate-shaped carrier 40 on which a holder 41 is mounted. A roller 9 is mounted rotatably between the holder 41 and the plate-shaped carrier 40, and, if necessary, a plurality can also be placed on the carrier 40 rollers 9. Under the roller 9, a drive element 8, shown in FIG. 5A in the mounting position. From this mounting position, the drive element 8 can be alternately rotated clockwise or counterclockwise to move to the functional position. In FIG. 5B, the drive element 8 is rotated to the right, so that the protrusion 80 can now engage with the drive element on the right side of the carrier 40. In this case, the drive element 8 is rotated to the stop 86 on the carrier 40 formed, for example, by embossing. Alternatively, the drive element 8 may also be rotated clockwise 90 °, as shown in FIG. 5C. Now, the drive element is oriented to the left, and the protrusion 80 is located on the left side of the carrier 40. In this case, the drive element 8 can be locked in functional positions from figures 5B and 5C, so as to ensure a stable location. It is the rotation of the drive element 8 that determines whether the running element 4 is a right or left running element, so it is possible to deliver structurally identical running elements 4, deciding already during installation whether this is the right element or the left one.

Figures 6A-6D depict in detail the hardware of FIG. 5. The drive element 8 comprises a socket slot into which a mushroom pin 82 or rivet can be inserted. The pin 82 contains an expanded head portion so as to prevent the removal of the drive element 8 from the plate-shaped carrier 40. This increases the stability of the drive element 8 and reduces the load on the middle axis 83. The axis 83 can also be formed as a mushroom pin or rivet for mounting, with the possibility of rotation, of the drive element 8 on the carrier 40. In this case, a mushroom pin 82 is fixed on the opposite sides of the carrier 40, which may or may not be engaged e with the corresponding socket depending from the pivotal movement of the drive member 80.

In FIG. 6D depicts in detail the abutment 86 on a plate-shaped carrier 40, which is embossed and forms an abutment for the actuating member 8. It can also be shown that the actuating member 8 has a channel for receiving the mushroom pin 82. A spring fixing wall may be provided on the channel 87 to lock the drive element 8 in a functional position and to prevent inadvertent release.

Figures 7A and 7B show a modified embodiment of the hardware, essentially corresponding to the hardware of Figures 5 and 6. Instead of the mushroom pin 82, there is a vertical tab 92 on the plate-shaped carrier 40, on which the hole 94 is made. Instead of the mushroom pin 82, the drive element 8 can be fixed on the tongue 92 - for this purpose, a retaining thickening 93 is introduced into the hole 94. Otherwise, the proposed fittings correspond to the above embodiment.

Figures 8A-8C depict another embodiment of the hardware in which there is an abutment 86 in the plate-shaped carrier 40, to which the drive element 8 can be brought. In the functional position, the drive element 8 further extends beyond the plate-shaped carrier 40, so that one edge 103 abuts against the leading edge of the plate-shaped carrier 40. This further increases the stability of the drive element 8. The rest of the running element 4 corresponds to the above embodiments Niya.

Figures 9A-9C show another embodiment of a running gear of a hardware according to the invention. The running element comprises a plate-shaped carrier 40 on which a roller 9 is mounted rotatably. Instead of a rotatable drive element, there is a displaceable drive element 10 arranged to move along a curved guide. To this end, two mushroom-shaped pins 13 are fixed on a plate-shaped carrier 40, each of which is engaged in the guide track 11. Accordingly, two guide tracks 11 having a curved portion 12 are formed on the drive element 10. In addition, on the drive element 10, a protrusion 14 is formed which extends perpendicularly from the plane of the front plate 60 and can be engaged with the seat on the driving member 7.

In FIG. 9D, the drive element 10 is shown in the mounting position. In this position, the roller 9 can be suspended on the rail 3 on the top panel 20. Once the installation is completed, the drive element 10 can be shifted along the mushroom pin 13 to reach the position of FIG. 9A. The drive element 10 is shifted so that the stop 15 of the drive element 10 is located below the roller 9, which prevents the rise of the running element. In this case, the spring 16 pushes the drive element 10 in a downward direction to prevent the drive element 10 from being unintentionally released from its functional position. The spring 16 holds the mushroom pins 13 fixed on the corner end portion 17. Although the end portion 17 of the fixation is formed only on the left guide track 11, a similar fixation can be implemented on the right guide track 11. If necessary, remove the running element from the rail 3, first you must again move the drive element 10 along the guide track 11, then, respectively, to raise the roller 9 and get the opportunity to bring it out of the rail 3.

In embodiments of the invention, the plate-shaped carrier 40 of the running member 4 may be made of a stamped and bent metal plate.

In the shown embodiments of the invention, the drive elements 8 are mounted for rotation or bias. Naturally, you can use other mechanisms to move the drive elements from the mounting position to the functional position.

The scope of the proposed fittings is not limited to furniture, and the corresponding sliding doors or sliding elements are also applicable in household appliances or other areas.
