Abstract

A drawer guide comprises a channel and a surrounding section for fixing one to the drawer and the other to the supporting structure. The section defines a compartment on either side of the channel. Each compartment contains a roller bearing comprising alternate rollers of two types, the axes of one type being at right angle to the rollers of the other type. Fig. 2 shows a perspective view of both profile sections in the operational position, with the rollers and wheels in the working position. Fig. 3 shows a detailed perspective view of a cage (omitted from Fig. 2), together with the method used to hold the rollers and wheels in position. <IMAGE>

Description

BER GUDES The purpose of the invention concerns a device for guiding drawers, specially designed and developed to permit the maximum amount of adjustment, absolute smooth operation and high load capacity.

This guide is of the type which comprises a number of rotating elements between the part integral with the cabinet and the part which is integral to the drawer and provides, as will be seen later, considerable advantages over known methods as there is an absence of lateral and vertical play associated with a minimum of components necessary to achieve this purpose.

According to the invention there is provided a drawer guide as set out in Claim 1.

An example of the invention will now be described with reference to the accarpanying drawings in which: Figure 1 shows a front view of the main profile section and a complementary profile section. The arrows indicate the effects of the guide system, in the horizontal plane and the vertical plane.

Figure 2 shows a perspective view of both profile sections in the operational position, with the rollers and wheels in the working position. A partial cross section is given and the cage which holds the rollers and the wheels in position has been omitted.

Figure 3 shows a detailed perspective view of a cage, together with the method used to hold the rollers and the wheels in position.

Figure 4 shows a detailed front view of the operational arrangement of the cage between the main profile section and the complementary profile section, without including the wheels and rollers in order to simplify the Figure and facilitate its comprehension.

With reference to the drawings the guide system illustrated in the drawings includes two parts, a main profile section 1 and a central body 5. One of these parts is fixed to the drawer and the other to the structure within which the drawer is to be mounted but the drawer and the structure are not shown as they do not form part of the invention.

The main profile section 1 has a main upright portion 21, a main 22 base portion fixed to the base of the upright portion, a smaller upstanding side 6 connected to the free end of the base portion 21, a channel 2 extending from the top of the side 6 towards the main upright portion 1 and a smaller upright portion 8 affixed to the free end of the channel 2. The section 1 thus provided a hollow L-shape, the outer vertical wall 21 being higher than the inner vertical wall 8.

The central body is of generally square section, partly cut away, having an upper horizontal portion 9 extending above the top of the smaller upright portion 8, a main side portion 5 extending between the main upright portion 21 and the smaller upright portion 8, a lower horizontal portion 4 extending between the channel 2 and the main base portion 22 but stopping short of the side 6 and a side portion 7 extending downwardly from the main upper portion 23.

In use, the side portion 7 and the side 6 are coplanar.

The components so far described define two chatters of rectangular section, an upper chamber defined at each side by the sides 8 and 7 and top and bottom by the horizontal portions 2 and 23, and a lower chamber defined by the sides 6 and 5 and the horizontal portions 2 and 4. Within each chamber is a roller bearing mounted in a cage, the roller bearing comprising rollers with horizontal axes alternating with rollers of vertical axes, the diameters of the rollers being sufficiently large as to keep the adjacent portions of the main profile section and the central body apart.

Figure 3 shows an exploded view of the rollers 3 and 14 in a cage 11 of nylon material. The cage 11 is formed with openings 12 for the rollers 3 having horizontal axes and 13 for the rollers 14 having a vertical axes. In Figure 3, the cage is in two parts, one part for each chamber, joined together by a side plate 15 and being formed with a central slot within which the channel 2 and the upright portion 8 of the central body are received. The diameters of the rollers 3 and 14 are greater than the width of the corresponding apertures in the cages so that the rollers extend from the cage to engage the profile section 1 and the central body 5.

Surfaces 1 and 7 are suitable for fixing to the drawer and the supporting structure.

Claims

CLAIMS.

1. A drawer guide comprising two linear sets of roller bearings arranged one on each side of a channel forming part of a profile section, the rollers of a bearing set including rollers of one type separating rollers of a second type whose axes are at right angles to the rollers of the first type, the diameter of the rollers of each type exceeding the length of the rollers of the other type, the guide further comprising a second section defining a compartment on either side of the channel within which a respective set of rollers is located.

2. A guide as claimed in Claim 1 wherein the profile section comprises walls at either end of the channel, one extending in the opposite direction to the other and both at right angles to the channel, said walls defining said compartments with the channel and the second section.

3. A guide as claimed in Claim 1 or Claim 2 wherein said two compartments are of different widths and the rollers of one type of the two sets are of corresponding by different diameters.

4. A drawer guide substantially as herein described with reference to the accompanying drawings.
