Definitions

• the present invention relates to a sliding door fitting for furniture with a guide rail formed from at least two rail parts, which can be fixed to a furniture body and along which at least one guide part is guided, which can be fixed to a sliding door in order to keep it movable and guided on the furniture body, wherein the at least two rail parts are connected to one another in the butt area via a butt connector.
• a guide rail is composed of at least two rail parts that are aligned in the joint area.
• a guide element is mounted on the joint area, which forms a guide track laterally next to the track of the guide rail, so that a roller rolls on the guide track in the joint area and thus the guidance in the joint area is taken over by the guide track.
• the rail parts are provided with recesses in the joint area, making the manufacture and assembly of the sliding door fitting complex.
• Another similar sliding door fitting is shown. WO 2021/023772 .
• the EP3 653 821 discloses a guide device for sliding doors in which a guide element is inserted into the track in a joint area between two rail sections, allowing guidance to be provided either by a main roller or an auxiliary roller.
• the provision of two rollers next to each other results in a bulky design and complex assembly.
• Another disadvantage of the upwardly open guide rails is that they become dirty over time, which adversely affects smooth running.
• At least one support roller is fixable and rotatably mounted on the furniture body in a joint area between the at least two rail parts, by means of which support roller the at least one guide part can be supported when traveling over the joint area of the guide rail.
• This allows a stationary support roller to be used to bridge any unevenness in the joint area between the two rail parts, in that the support roller supports the guide part when the at least one guide part moves over the joint area.
• a corresponding guide is essentially provided on an underside of the guide part so that even after extended periods of use, no impairments due to soiling occur.
• the transition between the two rail parts can be optimized.
• a guide track is formed on the at least one guide part, which can roll on the support roller.
• the guide track can have a length between 1 cm and 8 cm, in particular 2 cm and 5 cm, in order to be able to support the guide part over a certain distance.
• the guide track can have a curved section for raising and lowering the guide part, so that when traveling over the impact area, the guide part is first raised and then lowered.
• the at least two rail parts are connected to one another in the butt area via a butt connector.
• the at least one support roller is rotatably mounted on the butt connector.
• the butt connector can form a spacer so that the two rail parts are arranged at a predetermined distance from one another. Part of the butt connector is thus located as an extension of a guide on the two rail parts.
• This transition area can optionally have a depression or recess, since in this area the guide part is supported by the support roller.
• a butt connector is mounted between the rail parts, on which at least two support rollers are rotatably mounted, wherein at least one of two guide parts can be supported via each support roller.
• a first support roller can thus support a first guide part along a first guide on the guide rail, and a second support roller can support a second guide part that can be moved along a second guide on the guide rail. This allows sliding doors arranged at different levels to be guided on the guide rail in a compact manner.
• the two support rollers can be arranged one above the other in the vertical direction, so that the required installation space in the horizontal direction is minimal.
• At least one guide roller is provided on the at least one guide part, which can roll along a track on the guide rail. This allows the guide part to be moved along the guide rail with minimal force.
• at least one guide roller at least one sliding element can also be used to guide the guide part along the guide rail.
• the guide rail preferably features two spaced-apart guides, each for a guide part.
• the guides can be arranged vertically one above the other to minimize installation space.
• each guide part is preferably mounted vertically on a mounting element fixed to the sliding door. This allows the guide part to move smoothly along the guide rail, and the flexibility also allows for compensation of assembly tolerances. If, however, the weight of the sliding door is supported by the guide part, it is preferably rigidly fixed to the sliding door.
• a piece of furniture according to the invention comprises a furniture body, in particular in the form of a cabinet, and at least one sliding door, which is mounted on the furniture body via a sliding door fitting.
• Each sliding door can be suspended from a top shelf via at least one runner on a guide rail, and the guide rail is fixed to a base of the furniture body to ensure the alignment of the sliding doors.
• the inventive arrangement of at least one support roller in the joint area between two rail parts can be provided both on the guide rail on the floor and optionally on the running rail on the top floor.
• a piece of furniture 1 is designed as a cabinet and comprises a furniture body 2, on which a front sliding door 3 and a rear sliding door 4 are movably mounted at an opening of the furniture body 2. It is also possible to provide more than two sliding doors 3 and 4 on the furniture body 2 in order to close an opening.
• a guide rail 5 is fixed, on which the front sliding door 3 is held via guide parts 6 and the rear sliding door 4 is held via guide parts 7.
• FIG. 2 A sliding door fitting is shown on the furniture 1, which is arranged on a base 9 of the furniture body 2.
• the sliding door fitting comprises a guide rail 10 fixed to the base 9, on which two superimposed guides 11 and 12 are formed.
• the guide rail 10 is fixed to an end face of the base 9 or a base.
• the front sliding door 3 has a guide part 13 in its lower area, by means of which the sliding door 3 is guided along the guide 11.
• a guide roller 15 is rotatably mounted on the guide part 13, which rolls along a track on the guide 11.
• the rear sliding door 4 is provided with a guide part 14, on which a guide roller 16 is rotatably mounted, which rolls along the guide 12.
• sliding elements can also be arranged along the guides 11 and 12, alternatively or in combination with these.
• two support rollers 24 and 26 are provided on the furniture body, by means of which the guide parts 13 and 14 can be supported over a certain distance.
• the guide rail 10 is shown during assembly.
• the guide rail 10 consists of at least two rail parts 10a and 10b, which are connected to one another in a butt area via a butt connector 20.
• the butt connector 20 comprises pins 21 protruding on opposite sides, which are inserted into a cavity at an end section 19 of the guides 11 and 12.
• the end sections 19 taper towards the butt area, but can also be formed with a constant cross-section across the guides 11 and 12.
• a plate-shaped spacer 22 is provided between two pins 21, which is arranged between the two end sections 19 and specifies the distance between the two rail parts 10a and 10b in the butt area.
• the butt connector 20 comprises a lower holder 23 on which a lower support roller 24 is rotatably mounted. Furthermore, an upper holder 25 is provided on which an upper support roller 26 is rotatably mounted.
• FIG 3B The assembled position of the butt connector 20 is shown, which is arranged in the joint area between the two rail parts 10a and 10b. It can be seen that the end sections 19 of the two guides 11 and 12 taper towards the spacer 22, thus forming an upper section of a guide track in a trough shape. Optionally, this section can also be linear.
• the guide part 13 for the front sliding door 3 comprises a mounting element 30, in particular a mounting plate, which is fixed to a rear side of the front sliding door 3.
• a holding element 31 is slidably guided on the mounting element 30, so that the guide part 13 can move vertically relative to the sliding door 3.
• the holding element 31 is connected via a horizontal connecting section 32 to a further holding part 33, on which the guide roller 15 is rotatably mounted.
• the guide roller 15 is surrounded by a bracket 34, to which an attachment 35 with a guide track 36 is fixed.
• the attachment 35 is connected to two pins 37, which pass through openings 39 in the attachment 35 and protrude laterally from the bracket 34.
• the attachment 35 is fixed between the pins 37 and a holding section 38 on the top side of the bracket 34.
• the attachment 35 can also be formed integrally with the holding part 33 or can be fixed to the holding part 33 via other fastening means.
• a protruding web 17 is formed on the holding part 33, which engages behind the guide roller 15 below and laterally and thus prevents the sliding door 3, in the mounted position, from being movable together with the guide part 13 in a direction towards the furniture body 2.
• the guide part 14 for the rear sliding door 4 also comprises a plate-shaped mounting element 40, which can be fixed to the rear of the sliding door 4 and on which a holding part 41 is guided so as to be displaceable in the vertical direction.
• the holding part 41 comprises a protruding bracket 42, on which the guide roller 16 is rotatably mounted.
• an axle 43 is provided on the bracket 42.
• an attachment 45 is fixed to the bracket 42, which engages over the guide roller 16.
• the attachment 45 is held on the bracket 42 via two pins 47.
• a guide track 46 is formed, along which the support roller 26 can roll.
• the attachment 45 can optionally also be formed integrally with the bracket 42 or the holding part 41 or can be connected via other Fasteners can be used to fix it thereto.
• a protruding web 18 is also provided on the holding part 41, which is arranged below the guide roller 16 and thus prevents the rear sliding door 4 from being lifted upwards.
• the butt connector 20 for connecting the rail parts 10a and 10b is shown.
• the upper support roller 26 on the holder 25 and the lower support roller 24 on the holder 23 are connected to one another via a flexible web 27, which elastically arranges the two holders 23 and 25 under load to compensate for tolerances.
• the support rollers 24 and 26 can be made of the same or a different material than the holders 23 and 25, in particular of a softer elastomer material to prevent noise.
• the butt connector 20 can be manufactured in one piece using a two-component injection molding process if sliding elements are used instead of the guide rollers 15 and 16.
• FIG 7A The sliding door fitting is shown on the furniture body 2 in an area spaced from the abutment area.
• the guide roller 15 on the guide part 13 rolls on the guide 12, while the guide roller 16 on the guide part 14 rolls on the guide 11.
• the guide track 46 is arranged at least partially below an upper side of the support roller 26.
• the guide track 46 is located at a distance from the support roller 26 in the longitudinal direction of the guide rail 10.
• FIG 8A The position is shown when the guide parts 13 and 14 each move over the joint area between the rail parts 10a and 10b and the joint connector 20.
• the attachment 45 is supported on the guide part 14 via the support roller 26, which rolls along the guide track 46.
• the attachment 45 is raised when the support roller 26 is moved over, since the guide track 46 is curved downwards. By raising the attachment 45, the guide part 14 is also displaced upwards relative to the mounting element 40.
• the upward movement of the guide part 14 slightly lifts the guide roller 16 from the track of the guide 12, so that at least over part of the path of the support roller 26 along the guide track 46, the guide is shifted from the guide roller 16 to the support roller 26.
• the lifting movement of the guide roller 16 is slight, for example, between 0.5 and 5 mm, so that lateral guidance is still ensured despite the lifting movement due to the grooved shape of the guide roller 16.
• the lifting of the lower guide part 13 via the guide track 36 on the support roller 24 takes place in the same way as by moving the guide track 46 along the support roller 26.
• FIG 9 the different positions of the guide part 14 are shown when traveling over the butt area of the guide rail 10, which is not shown here for the sake of simplicity.
• the guide part 14 moves with the guide roller 16 to the butt connector 20, and the upper support roller 26 provided on the butt connector 20 comes into contact with the guide track 46, which is curved downwards and has an ascending and a descending area that is curved in the middle area.
• the middle area can also be designed as a linear horizontal line.
• this shape of the guide track 46 raises the attachment 45 with the guide part 14 until the support roller 26 travels over the lowest area of the guide track 46, as can be seen in the middle illustration.
• the support roller 26 comes into contact with a sloping area of the guide track 46 until the contact between the support roller 26 and the guide track 46 breaks off and the guide roller 16 now rolls on the guide 12 of the guide rail 10.
• the guide track 46 can have a length in the longitudinal direction of the guide rail 10 preferably between 1 cm and 5 cm, so that in the joint area of the two rail parts 10a and 10b, the support roller 26 takes over the vertical guidance of the guide part 14. The guidance of the other guide part 13 for the front sliding door 3 takes place in the same way.
• the guide tracks 36 and 46 are curved downwards so that the guide parts 13 and 14
• the guide elements 13 and 14 can be raised when the joint area is crossed. It is, of course, also possible to have only a slight curvature or to omit it entirely in order to achieve the most linear movement possible of the guide elements 13 and 14.
• the butt connector 20 with the support rollers 24 and 26 is arranged on the lower guide rail 10. It is of course also possible to design the upper guide rail 5 with two rail sections equipped with a butt connector with support rollers to support the guide sections 6 and 7 when passing over the butt area, whereby the weight forces of the sliding doors 3 and 4 can then also be absorbed by the support rollers.
