Definitions

• the present invention relates to a pull-out guide set for drawers or the like Profiles of the carcass rails are guided, wherein they run on the lower and / or upper horizontal webs of the carcass rails.
• Such drawer pull-outs consist of rails attached to the drawer and / or the furniture body, along which the rollers, possibly with a tilting function, and support rollers of the drawer are guided when the drawer is pulled out.
• These include the drawer pull-out, for example disclosed in EP 820 712 A2.
• a drawer If a drawer is pulled out, its guidance loses lateral stability the further the drawer is pulled out of the furniture body.
• the distance between supporting rollers and rollers with a tilting function is small, so that leverage is created.
• Cupboard depth or pull-out depth - the rollers in operation reduce the lateral stability of the extended drawer.
• the lateral stability is determined by the actual role play and the possibility of each individual drawer side to move freely with regard to the pull-out depth, whereby the rollers on one drawer side rotate counter to the rollers on the opposite side due to the slight lateral pivoting movement.
• the possible swivel play of the pulled-out drawer is further increased with the increasing width of the drawer.
• the aim of the invention is to increase the lateral stability of partially or fully extended drawers by largely preventing their horizontal swivel play.
• the desired improvement in lateral stability is achieved according to the invention in that at least two rollers arranged on opposite sides of the drawer are connected to one another in a rotationally secure manner.
• a lever function is created, the supporting and tilting forces being guided via rollers.
• a twist-proof connection is provided, preferably a tube or a rod, which is fixed, for example, by wedge connections on the rollers, which effects a synchronization of the rotation of the rollers on their axis.
• the lever loading of the extended drawer on the castors is sufficient to suppress slipping sideways between the running surface and the castor. The drawer is thus held in the extended position without swiveling sideways.
• rollers and / or the guideways are advantageous to equip the rollers and / or the guideways with adhesion-supporting surfaces, such as, for example, with quiet rollers.

• FIG. 2 is a sectional view of two guide rails with a roller
• Fig. 3 shows an exploded view of a roller according to the invention
• FIG. 4 shows an exploded diagram of one side of a drawer pull-out according to a further exemplary embodiment of the invention
• FIG. 5 shows a side view of this exemplary embodiment
• Fig. 7 is a section along the line A-A of Fig. 5 and
• Fig. 1 shows an exploded view of a drawer slide with a drawer rail 1, which is attached on both sides to a - indicated by dashed lines - drawer and a body rail 2, which is attached to the furniture body.
• the body rail 2 is approximately U-shaped, a web of the U being designed as a mounting edge 2a for attachment to the interior surface of the furniture body and the two further horizontal webs 2b and 2c serving as running surfaces for the roller 3.
• the horizontal web 1 a of the drawer rail 1 serves as the running surface for the support roller 4.
• the roller 3 is guided within the body rail 2, between the two horizontal webs 2b and 2c, with the roller 3 at the beginning of the pull-out movement runs on the lower horizontal web 2b, but acts as a tilting roller with increasing pull-out, is pushed upwards by gravity due to the weight of the drawer over the drawer rail 1 and then rolls on the upper horizontal web 2c with further pull-out.
• the lateral guidance of the rollers 3 is effected by the provided guide projections 2d and 2e.
• the guide projection 1 b lies laterally on the support roller 4.
• the drawer is thus held in the extended position, which can also be slightly offset, as far as the guide rails allow.
• the lateral stability is directly increasing
• Fig. 2 shows a sectional view of a drawer slide guide, where B indicates the axial position of the roller 3 at the start of the pull-out and C the axial position of the roller 3 during rolling on the upper horizontal web 2c, i.e. H. on the upper tread.
• Fig. 3 shows an exploded roller 3 with directly connected mounting pin 5 and associated connecting rod 7.
• the connecting rod 7 is in this embodiment on both sides by a wedge connection 6 both on the roller 3 via pin 5, and - not shown - on the opposite roller fixed against rotation.
• the connection between the rollers 3 and the way in which they are attached to the rollers 3 can be made as desired, for example by means of pins or couplings, as long as it is secured against rotation.
• a tube can also be provided.
• the pull-out guide according to the embodiment of FIGS. 4 to 8 consists of the drawer rail 11, the body rail 12 and the central rail 15.
• the drawer rail 11 is provided at the rear end with a roller 13 which runs on the lower runway 12e of the body rail 12.
• a support roller 14 for the pull-out rail 11 is supported on the body rail 12 at the front end.
• a further roller 16 is mounted, which is supported on the upper horizontal web 12c of the body rail 12 when the drawer is pulled out.
• the drawer rail 1, 11 also forms the drawer frame.
• the middle rail 15 is supported on a profile 17 formed on the drawer rail 11 and is displaceable thereon.
• the sliding support or guidance of the central rail 15 on the drawer rail 11 is possible because the central rail 15 is completely unloaded when the drawer is pulled out in the first pull-out area.
• a slide 18, preferably made of plastic is arranged, which surrounds the profile 17 in a C-shape.
• the rollers 16 of the center rails 15 are rotatably connected to one another by an axis 20, as a result of which the same lateral stability as in the previously described exemplary embodiment is achieved. If the drawer is pulled out of the furniture body, the rollers 13 of the drawer rails first roll off on the lower horizontal webs 12c of the body rails. With a certain extension path, the drawer tilts around the support rollers 14 and the rollers 16 of the middle rails 15 roll on the upper horizontal webs 12c of the body rails 12. The rollers 13 of the shop rails 11 are unloaded in this front extension path.
