Abstract

The cabinet mounted rail 1 of a drawer slide mechanism is moveable laterally with respect to the cabinet wall 4 under resilient flexure of arm 2' of the mounting bracket (which arm 2' is only secured at its upper end to wall 4), the lateral position being selected and retained by an eccentric cam 6 mounted on a vertical axis X-X and bearing on wall 4. The periphery of the can 6 bears radially extending teeth 9 of resilient material to act as detents, and may bear on operating arm 13. <IMAGE>

Description

SPECIFICATION Laterally adjusta 191s pull-out assembly for drawers of the like The invention relates to a laterally adjustable pull-out assembly for drawers or the like comprising a supporting rail on the side of the body, a guide rail on the side of the drawer and an eccentric as an adjusting means rotatably mounted around an axis (X-X) vertically extending to the sliding flange.

When mounting drawers in cupboards or closets a possiblity of adjusting the supporting rail on the side of the body or the guide rails on the side of the drawer, of the slide assembly is often desired in order to obtain a precise lateral alignment of the drawers.

A lateral adjustment of the supporting rails is desired so that the front panels of the inserted drawers are exactly in the desired positions and, further, that quiet motion and an improved fit of the drawer in the puil-out assembly are obtained.

It is further desired that the adjustment of the supporting rail can be made without fully extracting the drawer from the body of the piece of furniture, i.e. that the adjusting means are substantially accessible from the front of the piece of furniture.

With prior art adjustment means, such lateral adjustment of the supporting rail is possible in one direction only, i.e. away from the side wall of the body, because the eccentric is only able to urge the supporting rail away from the side wall. When the distance between the supporting rail and the side wall is too big, a backward rotation of the eccentric is not sufficient, but the supporting rail has to be forced to te side wall of the body by exerting lateral pressure.

It is the object of the invention to provide a laterally adjustable supporting rail of the above-described kind in which all -operational advantages are preserved and which is of simple structural design also when the drawer is anchored in the pull-out assembly, which ensures safe operation (i.e. that an unintentional adjustment of the supporting rail is prevented). An advantageous embodiment allows an adjustment in the direction towards the side wall as well as away from the body side wall within the normal operational range of the adjusting means.

According to the invention, this is achieved by mounting the eccentric, which is a plastics wheel or a segment of a plastics wheel with flexible teeth, on an elastic fastening member for the supporting rail and by adapting it to rest against the furniture side wall, when the supporting rail is in the mounted position.

By providing the toothed wheel, the teeth of the eccentric brace themselves on the furniture side wall or a corresponding abutting wall in such a manner that an unintentional rotation of the eccentric is efficiently prevented.

By arranging the eccentric on a separate fastening member of the supporting rail, the eccentric is more easily accessible. Further, a sort of elastic support for the supporting rail is obtained by the combined action of the fastening member and the supporting rail, said elastic support effecting that the supporting rail is pressed against the furniture side wall by the fastening member, when the eccentric is correspondingly rotated. An advantageous embodiment provides that the fastening member has a profile with a vertical fastening flange and a horizontal supporting flange for the supporting rail and that the eccentric is mounted on the supporting flange.

This resilience of the fastneing member can be increased still by providing the fastening flange with a punched flap on which a fastening screw or the like engages.

A further embodiment of the invention provides that an adjustment member is moulded to the eccentric. In this embodiment adjustment can be effected without tools.

In the following two embodiments of the invention will be described in greater detail by means of the figures of the attached drawings without being limited thereto.

Figure 1 shows a schematic view of a supporting rail according to the invention, Figure 2 shows a side view of a supporting rail according to the invention, Figure 3 shows a front view of a second embodiment of a supporting rail according to the invention, and Figure 4 shows a schematic view of a pullout assembly with a supporting rail according to the invention.

The supporting rail 1 according to the invention is fixed to the furniture side wall 4 by means of two fastening members 2, 3, the fastening members 2, 3 being screwed to the body side wall 4 by means of screws 5.

The fastening member 2 is, as can best be seen in Fig. 3, substantially L-shaped and has a vertical fastening flange 2' and a horizontal supporting flange 2" for the supporting rail 1.

A plastics wheel or a segment of a plastics wheel is rotatably mounted on the horizontal supporting flange 2" on an axle 7, said wheel or said segment being provided with an eccentric hub 8, thus forming an eccentric 6.

The plastics wheel or the plastics segment is further provided with teeth 9 bracing themselves on the body side wall 4, as illustrated in section A of Fig. 3.

The teeth 9 and their slight resilience provide a safety means for the eccentric 6 by efficiently preventing an unintentional rotation thereof. In the embodiment according to Fig.

3 to 6, an adjustment member 1 3 is moulded to the eccentric 6 for rotating the same. By means of the moulded adjustment member 13, the eccentric can be rotated without any tool.

In the embodiment according to Fig. 1 and 2, rotation of the eccentric 6 is effected by pressing from the front of the piece of furniture on a tooth 9 of the eccentric 6 by means of a suitable tool, e.g. a screw driver, in the direction of arrow V of Fig. 2, thereby turning the eccentric.

In Fig. 3, the eccentric 6 and the supporting rail 1 are shown in the zero position. By turning the eccentric 6, the supporting rail 1 with the fastening member 2 are moved from the body side wall 4 in the direction of arrow F.

Due to the resilience of the metal fastening member 2, the supporting rail 1 can also be moved in the direction towards the side wall, when the eccentric 6 is correspondingly turned.

In order to improve the resilience of the fastening member 2, it is provided with a flap 10 on which the fastening screw 5 engages directly.

Fig. 4 shows a schematic view of the arrangement of the supporting rail according to the invention, the drawer 11 with the guide rail 12 also being illustrated. The guide rail 1 2 is mounted in the supporting rail 1 by means of rollers, for example. The axis of rotation and the bearing axle 7 of the eccentric 6 are vertically aligned in the mounted position.
