DESCRIPTION:
BRIEF SUMMARY
This invention relates to a drawer slide, a drawer slide assembly, and furniture utilizing such a drawer slide assembly, the term furniture being used herein to include items such as filing cabinets, and office furniture together with domestic furniture such as bedroom and kitchen drawer units.
It should be noted that the term "drawer slide" as used herein is a term known in the furniture art, and sometimes substituted by the term "drawer runner".
British Patent 1046638, and British Patent 2130472 (in the name of the inventor in relation to the present application) both disclose arrangements wherein a single drawer slide, at each side of a drawer, cooperates with rollers carried by the drawer and the carcass of the cabinet housing the drawer, slidably to support the drawer within the cabinet.
It is an object of the present invention to provide a drawer slide which can be manufactured by cold rolling of mild steel strip and which can be readily assembled in a situation in which both the drawer and the drawer cabinet nave been preassembled. The arrangement illustrated in British Patent 1046638 is unsuitable for manufacture by cold rolling of mild steel strip, and has several inherent disadvantages arising from the need to facilitate assembly to preconstructed drawers and cabinets. For example, the drawer rollers are secured to the drawer structure by screws passing completely through the drawer structure and so having their heads exposed within the drawer space, and the end stops of the runner are separately formed, detachable components. By comparison, the construction disclosed in British Patent 2130472 does lend itself to manufacture by cold rolling of mild steel strip, but the disclosure is of a drawer slide arrangement which can only be assembled prior to completion of the construction of the carcass of the cabinet housing the drawer.
It is one object of the present invention to provide an improvement over the drawer slide arrangement illustrated in British Patent 2130472 in which assembly to a preconstructed drawer and cabinet is facilitated.
In accordance with the present invention there is provided a drawer slide formed by cold rolling metal strip and shaped, in cross-section to define first mutually presented tracks for receiving and cooperating with a first set of rollers carried, in use, by a drawer, second mutually presented tracks for receiving and cooperating with rollers carried in use by the drawer receiving cabinet, a first web portion integrally interconnecting the first tracks, a second web portion integrally interconnecting the second tracks integral stop means closing both ends respectively of a first channel defined by one of the first and second weds and its respective tracks, a cut-out provided in the outer track of the first channel to facilitate insertion of the respective rollers into said first channel, integral stop means closing an end of a second channel defined by the other of said first and second webs and the respective tracks, and an access aperture in the web of said second channel providing, in use, access through the web to means for securing the respective rollers to the drawer or to the cabinet carcass.
The cut-out is preferably provided adjacent an end of the drawer slide, the integral stop means of the second channel being provided at the end thereof remote from the cut-out. Buffer means is preferably provided associated with the integral stop means adjacent the cut-out.
The buffer means associated with the stop means adjacent the cut-out preferably comprises a shock absorbent resilient member arranged to partially close the cut-out, in use, to restrict removal of the roller(s) from the first channel.
Alternatively, the cut-out may be spaced from an end of the slide.
Preferably, the drawer slide further comprises buffer means associated with at least one of the integral stop means of the first and second channels.
Preferably, each of the first and second tracks is of part circular cross-section.
Alternatively, each of the first and second tracks may be of generally `
