Abstract
Description
[0001] Drawer guide
[0002] The present invention relates to a pull-out guide for furniture, with a one-piece support bracket which has a mounting web which can be fixed to a wall and a support web which projects from the mounting web, wherein a track is provided at an angle from the support web, on which track at least one movable rail is mounted, wherein openings for the introduction of fastening means are formed on the mounting web at a front and rear end in the longitudinal direction.
[0003] DE 10 2019 111 292 A1 discloses a guide rail for a drawer slide in which embossed grooves are formed between the openings of a retaining bracket to stabilize the retaining bracket. When inserting fasteners, especially screws, into the openings of the retaining bracket, chips can be forced out of the wall, contaminating the furniture body and posing a hygiene problem.
[0004] EP 2 429 340 A1 and DE 10 2013 010 577 A1 each disclose pull-out guides with a stationary cabinet rail that can be fixed to a furniture carcass via fastening means. For this purpose, a plurality of openings are provided in the cabinet rail, which are provided in a strip-shaped section positioned at a distance from the cabinet wall. As a result, when screwing in the fastening means, in particular the screws, chips can enter a gap between the cabinet rail and the wall, so that the chips can fall out at a later time and then have to be removed as dirt.
[0005] It is therefore an object of the present invention to provide a pull-out guide that can be effectively mounted on a wall and reduces or avoids problems caused by soiling.
[0006] This object is achieved with a pull-out guide having the features of claim 1. The pull-out guide for furniture according to the invention comprises a support bracket having a mounting bar that can be secured to a wall and a support bar that protrudes from the mounting bar and on which at least one movable rail is held. The mounting bar extends over almost the entire length of the movable rail. Openings for inserting fastening means, such as screws, are formed on the mounting bar, with at least one suction opening having an area of more than 4 cm 2 The comparatively large suction opening allows any chips to be vacuumed away after the drawer slide is installed. A suction device, such as a vacuum cleaner with a suction tube, can be placed against the suction opening. This enables effective assembly and prevents contamination of the furniture during subsequent use.
[0007] Preferably, the mounting web has a lower wall contact area and an upper wall contact area perpendicular to the longitudinal direction, with an offset arranged between the lower and upper wall contact areas. The offset between the wall contact areas provides a channel for vacuuming away the chips. The offset and the lower wall contact area or the upper wall contact area can be connected via two strip-shaped profiles. A front and a rear hole row section are preferably formed on the offset, each having a plurality of openings for inserting fastening means. The at least one suction opening is arranged between these two hole row sections.
[0008] In a further embodiment, the offset has a height, and the suction opening is designed with a lower height of at least 60% of the height of the offset. The respective height preferably refers to the vertical extension in the mounted position.
[0009] Preferably, an edge of the at least one suction opening can be positioned at the offset by 0.2 mm to 4 mm from the wall via profiles. This also allows for the suction removal of contaminants that have accumulated on the mounting web on the side facing the wall. The offset of the one-piece support bracket preferably extends almost over the entire length of the track, which simplifies manufacturing.
[0010] Preferably, two strip-shaped profiles are formed on the mounting web, which can be placed against the wall, and the at least one suction opening is arranged between the two strip-shaped profiles. This allows the suction opening to be positioned at a distance from the wall via the strip-shaped profile, so that a suction channel is formed between the two strip-shaped profiles on the side of the mounting web facing the wall. This suction channel is defined by the mounting web, the two profiles, and the wall of the furniture body, so that when a vacuum cleaner is placed against the suction opening, the chips or other contaminants can be sucked away through the suction channel.Preferably, the openings for inserting fasteners are provided in the area of the suction channel, so that the fasteners are guided through the suction channel during assembly, and any chips generated during the insertion of the fasteners can be suctioned away via the suction channel. The strip-shaped profiles on the mounting web can preferably extend over the entire length of the support bracket.
[0011] The strip-shaped profiles can, for example, be formed by steps, with one section of the step being able to be placed against the wall of the furniture body and another section being spaced apart from the wall, forming a connecting bridge between the two profiles, where the suction opening is recessed. Instead of a step, ribs or other profiles can also be provided in the mounting bridge.
[0012] The suction opening preferably has a length of at least 25 mm. The length of the suction opening can be at least twice as large as the height of the suction opening. The size of the suction opening can, for example, be in a range between 4 cm 2 up to 20 cm 2 to enable effective suction through the suction opening.
[0013] The openings for introducing the fastening means are preferably arranged at a front and rear end of the mounting web. The suction opening is preferably arranged in a central region in the longitudinal direction of the support angle. A distance of at least 25% of the length of the support angle can be provided on both sides in the longitudinal direction to a respective end. As a result, when a suction device is placed against the suction opening, suction is carried out in both directions, so that contamination is removed from opposite sides of the support angle in the longitudinal direction. In a further embodiment, at least some of the openings for introducing fastening means have a shoulder that extends into the suction channel. The distance between the wall and the shoulder can be smaller than the distance between the wall and the suction opening. The shoulder can also serve as a spacer for the suction channel.
[0014] For precise positioning of the drawer guide, at least one bent projection can be formed on the mounting bracket, which can be inserted into an opening in the wall. Furthermore, the support bracket can be manufactured by punching or bending a metal sheet for efficient production. The punched-out area for the suction opening further enables material-saving production.
[0015] The invention will be explained in more detail below using an exemplary embodiment with reference to the accompanying drawings. They show:
[0016] Figure 1 is a perspective view of an inventive
[0017] drawer guide;
[0018] Figures 2A and 2B show two perspective views of the support bracket of the pull-out guide of Figure 1, and
[0019] Figures 3A and 3B show two views of the support bracket of Figure 2.
[0020] A drawer guide 1 comprises a support bracket 2, which can be mounted on a wall of a furniture body or household appliance via a mounting bracket 3. The support bracket 2 has a support bracket 4 that protrudes at an angle, in particular at a right angle, from the mounting bracket 3. A movable rail 5 is held on the support bracket, which can be moved along a guide track via rolling elements. One or more center rails for extending the drawer extension can optionally be provided between the movable rail 5 and the support bracket 2.
[0021] The mounting bar 3, which is essentially vertically aligned in the installed position, comprises openings 9 for inserting fastening means, such as screws. The openings 9 are circular and are preferably located at a front and rear end of the mounting bar 3. In a central region of the mounting bar 3, a suction opening 10 is formed, which has a larger area, in particular more than 4 cm 2, for example 5 cm 2 up to 20 cm 2 The suction opening 10 is rectangular in plan view and has a greater extension in the longitudinal direction of the drawer guide 1 than in the vertical direction, but can also have a different geometry. Preferably, the suction opening extends over at least 60% of the part of the mounting bar 3 that is arranged above the rail 5.
[0022] In Figures 2A and 2B, the support bracket 2 is shown without the rail 5 and the rolling elements. A raceway 6 for rolling elements is integrally formed on the support web 4, which is formed by an upwardly bent section on the support web 4. Optionally, instead of a one-piece design, a stationary rail can also be fixed to the support web 4.
[0023] The support bracket 2 has a bend 7 between the mounting web 3 and the support web 4, which can be reinforced by one or more beads 8. The beads 8 are formed by embossings that shape the metal sheet into reinforcement angles in the area of the bend 7. A lower wall contact area 31 and an upper wall contact area 33 are formed on the mounting web 3, between which an offset 32 is arranged.
[0024] Two strip-shaped profiles 11 are formed on the mounting web 3, each forming a step, so that a connecting web between the two profiles 11 can be positioned at a distance from a wall of the furniture body. The suction opening 10 is formed on this connecting web between the two profiles 11, so that the edge of the suction opening is also positioned at a distance from the wall. The suction channel 12 extends over the entire length of the mounting web 3 and thus forms a suction channel 12 on the side facing the wall, which is delimited by the connecting web between the two profiles 11, the wall of the furniture body and the two profiles 11. The suction opening 10 and further openings 9 for fastening means are provided in the area of the connecting web between the two profiles 11.Furthermore, at least one bent projection 13 is formed on the connecting web, which can be inserted into an opening in the wall of the furniture body for positioning the support angle 4.
[0025] The opening 9 on a front side of the suction channel 12 is formed as a front hole row section 91, and the openings 9 on a rear side are formed as a rear hole row section 92, with the suction opening 10 arranged therebetween. Figures 3A and 3B show the area of the suction channel 12 in detail, and the sectional view of Figure 3B shows that the suction opening 10 can be positioned at a distance from a wall on the rear side of the mounting web 3 by the two strip-shaped, stepped profiles 11.
[0026] At least some of the openings 9 for inserting fastening means have a shoulder 93 extending into the suction channel. The distance between the wall and the shoulder 93 can be smaller than the distance between the wall and the suction opening 10.
[0027] For assembly, the pre-assembled pull-out guide 1 can be positioned against a wall of a furniture carcass, with the optional projections 13 being inserted into corresponding openings in the wall. Fasteners, in particular screws, are then inserted into the openings 9, and the support bracket 2 is fixed to the wall. When the fasteners are inserted, chips can be removed from the wall, which are now located between the connecting web on the mounting web 3 and the wall of the furniture carcass. After assembly, the installer can hold a suction device, in particular a vacuum cleaner, with a nozzle against the suction opening 10 so that chips and other contaminants can be sucked out via the suction channel 12, preventing these from causing problems during later use of the furniture.
