Description

The present invention relates to accessories for a sliding door, in particular, for furniture containing a rail with at least one running track along which one or more rollers of the movable part can be moved, and an anti-removable device that is at least partially engaged from the bottom of the section running track of the rail.

Patent document EP 1388631 discloses a roller bearing for sliding doors, in which a safety catch is provided in which the movable shaped part is engaged with its rib from the bottom of the rail rib, which prevents the sliding door from being removed, while the shaped part must be displaced to remove the sliding door. Such anti-removable devices have proven to be effective, however, for the aforementioned safety grip, it is necessary to have a horizontal rib on the rail so that the shaped part can engage with it.

DE 102011050395 discloses accessories for a sliding door, on the movable part of which there is a pivoting arm that can engage with the edge of the running track to prevent the sliding door from being removed. In this case, the pivot arm is located at a distance from the roller so that in case of removing the sliding door, forces are applied not in the region of this roller. In addition, the space for accommodating the movable part with the safety grip is relatively large.

Thus, an object of the present invention is to disclose sliding door fittings with an efficient and compact safety catch.

This problem can be solved by means of accessories with distinctive features in accordance with paragraph 1 of the claims.

According to the present invention, the sliding door hardware comprises an anti-removable device in which a portion of the rail of the rail is at least partially closed by a rib, wherein the anti-removable device rib engages from below the rail in the region of at least one roller when viewed in the direction of the longitudinal direction of the rail. As a result, the fittings have a particularly compact design, since the movable part in the area of the roller additionally performs the functions of an anti-removable device. In addition, under load, the anti-release device can transmit forces to the moving part with an optimal ratio of the lever arms.

According to a preferred embodiment, the anti-release device comprises a pivot arm mounted to rotate about an axis extending parallel to the longitudinal axis of the rail. In this case, the pivot arm can be rotated between a fixed position in which the rail of the rail is at least partially engaged from below and a mounting position in which the rail of the rail is no longer engaged to allow mounting and dismounting of the sliding door. In the secured position, the pivot arm is preferably locked to prevent accidental release of the anti-seizing device.

To reliably prevent removal, the gap between the edge of the anti-seizing device and the bottom side of the rail is preferably less than the height of the side edge of the rail near the track. Thus, by means of a side face that prevents the roller and the sliding door from being removed from the running track in the lateral direction even in their raised position.

The pivot arm preferably has two arms between which the roller is located. Thus, in the case of a load, the force can be perceived by two shoulders that are spaced apart from each other, which also ensures stable fastening of the pivot arm. In addition, the location of the roller between the arms of the pivot arm provides essentially compact design.

According to yet another preferred embodiment, the first running track and the second running track are arranged vertically on the rail one above the other, which minimizes the area required for the fittings guiding the sliding doors. In this case, the rail can be made of a curved metal plate, which ensures minimal material consumption in the manufacture of the rail.

At least one tool socket is preferably provided on the pivot arm so that the anti-release device can also be rotated without actuating the handle. In this case, the tool socket can be located in the region of the axis of rotation of the pivot arm so that it is possible to insert the tool substantially parallel to the longitudinal direction of the rail. Thus, the anti-release device can be activated or deactivated even in confined spaces.

In yet another embodiment of the invention, an upward projection is located on said rib. This protrusion may correspond to the contour of the lower side of the rail, which provides an essentially reliable fixed position. In addition, if the rib under the roller is curved upward, the size of the gap under the rail can be reduced so that the rib can move under the rail without contact with it, but is located a short distance under the rail.

in FIG. 6A and 6B show a modified embodiment of the hardware of the present invention;

in FIG. 7A and 7B show a modified embodiment of the hardware of the present invention; and

in FIG. 8 is a side view showing yet another embodiment of the hardware of the present invention.

The cabinet furniture element 1 comprises a furniture case 2, on the upper panel of which there is a rail 3 for guiding the rear sliding door 4 and the front sliding door 5. A rail provided with a sliding or rolling track for guiding the sliding doors 4 can also be located at the bottom of the furniture case 2 and 5.

In FIG. 2 shows a front sliding door 5, held on the rail 3 with the possibility of movement by means of the movable part 6. At the top cover, behind the rail 3 there is a closer body 7, in particular of a shock-absorbed closer, the movable drive 8 of which passes through an opening in the rail 3. The drive 8 is connected with an activator 9 fixed to the movable part 6 so that the movement of the sliding door 5 at the closing and / or opening can be inhibited so that the sliding door 5 can automatically move to the extreme position.

On the rail 3 there is an upper track 10 and a lower track 11, while both movable parts 6 of the front sliding door 5 are held movably in the upper track 10, the rear sliding door 4 being guided in the lower track 11. The rail 3 is designed as integral with a curved metal plate and attached to said upper panel.

In FIG. 3A and 3B, the movable part 6 is shown in the mounting position, in which the roller 12 can be placed on the running track 10 of the rail 3. On the moving part 6, there is a pivoting arm of the anti-release device 20 having a rib 21, which in the locked position engages from the bottom of the running track 10. In the mounting position, the rib 21 is adjacent to the track 10. In addition, the pivot arm comprises two arms 22 that extend vertically and are combined into a horizontal portion 25 so that the track 10 is surrounded by a pivot track agom in the shape of "the U" or "C". The pivot arm is rotatably mounted about an axis 24 located in the region of the roller 12. The pivot arm comprises a handle 23 above the axis 24, which is slanted in the mounting position. The user can rotate it to the vertical, fixed position shown in FIG. 4A-4B.

In the fixed position, the rib 21 engages below the running track 10, the gap between the lower side of the running track 10 and the rib 21 being less than the height of the side face 13 adjacent to the running track 10, which prevents the door from moving through the face 13 when lifting the roller 12 and the sliding door . The rotary lever of the anti-release mechanism covers a section with a face 13 in the shape of the letter “U”. The shoulder 22 and the portion 25 are located on both sides of the roller 12, which ensures essentially the compactness of the movable part 6 in the region of the roller 12. The axis 24 of the pivot arm is located slightly above the axis of rotation 26 of the roller 12, but within the diameter of the roller 12 when viewed direction of its movement.

In FIG. 5A-5E, a rail 3 is shown, on which the movable part 30 for the rear sliding door 4 is movably held. The movable part 30 also includes an anti-removable device 40 with a pivot arm, the axis of rotation of which 46 is located in the region of the roller 12. The pivot arm contains a portion in the form the letter "U" with the upper horizontal rib 43, two vertical ribs 44 and the lower horizontal rib 41, and the lower running track 11 of the rail 3 is covered in the shape of the letter "C". A handle 42 protruding downward is made on the horizontal rib 41 of the anti-release device, which enables the pivot arm to be moved from the fixed position (Fig. 5A) to the mounting position (Fig. 5C).

The anti-detachable device 40 also contains two shoulders located on opposite sides of the roller 12. These shoulders are formed by horizontal ribs 41 and 43, as well as two vertical ribs 44 connected to each other through a common handle 42, which ensures essentially compact design of the movable part thirty.

In FIG. 5D and 5E show fittings with a movable part 30 at the time of lifting. The movable part 30 was raised so that the roller 12 moved away from the track 11. As a result, the rib 41 is adjacent to the lower side of the track 11 of the rail 3. Despite the fact that the roller 12 has been lifted from the track 11, it cannot be moved through the side face 14 of the track 11, preventing the movement of the roller 12 perpendicular to the longitudinal direction of the rail 3. Thus, the removal of the sliding door 4 can be reliably prevented even if the movable part 30 is lifted. Thus, the gap between the lower side of the track 11 and an edge 41 is less than the height of the side face 14 of the track 11.

In FIG. 6A and 6B show yet another embodiment of the hardware in which the construction of the rib 41 is substantially different from the construction in the embodiment of FIG. 5. On the side of the rib 41 facing the opposite side from the movable part 30, an upward protrusion 45 is formed so that the anti-detachable device 40 even better prevents the removal of accessories. The protrusion 45 has an input slope 47, directed essentially parallel to the lower side 49 of the track 11 of the rail 3, made in the form of the letter "V". Thus, when the movable part 30 is raised, the input slope 47 is adjacent to said lower side 49 so that when moving the movable part 30 forward, the fittings are repeatedly pressed in an obliquely downward direction by the initial slope 47. In addition, the rib 41 has an upper side 48 located below track 11.

In FIG. 7A and 7B show another exemplary embodiment of the movable part 30 ', in which the anti-release device has a rib 41', which, when viewed in a direction parallel to the longitudinal direction of the rail 3, is not even, but convex. The upward convexity 50 of the rib 41 'ensures that the gap between the lower side of the track 11 of the rail 3 below the roller 12 is smaller than the gap adjacent to the side ribs 44. The convex 50 can be located substantially close to the bottom side of the track 11, since the fittings under the roller 12 are resistant to tolerances. Otherwise, the exemplary embodiment of the invention of FIG. 7A and 7B corresponds to the exemplary embodiment of FIG. 5.

In FIG. 8 shows yet another embodiment of the fitting, in which (in addition to the embodiment of FIG. 5), a tool socket 60 is provided in the region of the rib 43. The tool socket 60 ensures that, if necessary, the anti-release device can be activated not only by the handle 42, but also by the tool, which can be mounted on the pivot arm substantially parallel to the longitudinal direction of the rail 3. The tool socket 60 is shown as a hexagonal recess, but, of course, it can be made in the form of a slot, a recess in the shape of a star, a cross-shaped slot, or other tool sockets.
