Furniture with drawers and roller runners

The innovation relates to a piece of furniture with a drawer and roller drawer runners, in which each Long side of the drawer consisting of a body rail and a drawer rail A pair of rails is provided and each rail has an end roller on the horizontal webs of the other Rail are guided.

There are roller guides of this type are known in which the body rails and the drawer rails have a U-shaped cross-section and the horizontal webs of these rails are flat and thus have no profiles in which the end rollers could be forcibly guided.

There are also ball extracts known in which zwisehen the horizontal bars of the cabinet rail and the drawer rail are arranged in an eiram cage

Balls are provided. The horizontal bars of these rails have guide grooves for the balls equipped.

The sliding guides of the type mentioned above have poor lateral stability due to the overlapping manufacturing inaccuracies and manufacturing tolerances of the piece of furniture, the drawer, the rails and the end rollers, which means that the proper operation of the drawer is impaired ( 10.

The innovation is based on the task of designing furniture of the type mentioned so that through the formation of the sliding guides of the drawer sufficient lateral stability in his the entire range of motion.

This object is achieved according to the innovation in that on the one hand the body rails and on the other hand the Drawer rails have the same cross-section, the horizontal webs are provided with guide grooves are, in the appropriately shaped outer edges ^ - engage the end rollers and that only the Have end rollers of a drawer side axial play.

In the case of the innovation, the end rollers of the pair of rails on one longitudinal side of the drawer are forcibly guided, while the end rollers of the pair of rails on the other side of the drawer have axial play. Due to the forced guidance of the end rollers on one side of the drawer good lateral stability is achieved over the entire range of movement of the drawer,

while the axial play of the end rollers provided on the other long side of the drawer Pair of rails Manufacturing inaccuracies and manufacturing tolerances of the interacting functional parts can be bridged.

An embodiment of the innovation is in the drawings and is described below. Show it:

Fig. 1 shows a furniture body with inserted drawer and with associated sliding roller guides in the

Vertical section,

Fig. 2 a pair of rails of the sliding roller guide in side view,

Fig. 3 is a section along the line III-III in Fig. 2, FIG. 4 shows a section along the line IV-IV in FIG. 2.

The furniture body 1 is provided with a drawer 2, on the side walls 3 of which drawer rails 4 are attached are. For this purpose, the drawer rails have tabs 5, which from the vertical web of the Drawer rails are shaped and provided with a through hole for a fastening screw, which in the respective side wall 3 is screwed in.

The drawer rails 4 fixed on both long sides of the drawer have a matching one Cross-section on. They are equipped with horizontal bars, each with a guide groove 6 for an end roller 7, which is rotatably mounted on the body rail 8. For this purpose there is a pin on the cabinet rail

9 attached, which is equipped with a stop disk 10 at its free end. The stop washer

10 is provided in a cylindrical recess 11 of the end roller.

While the front end rollers 7 are rotatably mounted on the body rail 8, the rear end rollers are 12 rotatably mounted on the drawer rail 4. The horizontal bars of the cabinet rails also have guide grooves 13 equipped for the end rollers 12. To store the roll 12 is on the drawer rail a pin 14 set, which is equipped with a stop disk 15, which is in a cylindrical recess the end roller 12 is arranged.

In the embodiment shown in FIG. 1, the drawer 2 is forcibly guided on the left side. The end rollers 12 and 7 provided on the left side have no axial play. The width the stop disk 10 or 15 corresponds to the width of the cylindrical recess in the end roller. The final roles are also positively guided in the guide grooves of the horizontal webs.

On the right side of the drawer according to Fig. the end rollers 7 and 12 have axial play with respect to the associated bearing journals. This is because of this achieves that the width of the stop disks 10.15 is less than the width of the cylindrical recess 11 in the named end roles. Because of this axial play of the end rollers on one longitudinal side of the drawer there is a possibility of setting the interacting functional parts.
