Pull-out shelf support systems
First Claim
1. In a pull-out shelf support system within a fixed frame comprising, for each side of a shelf, an intermediate member for travel partially with the shelf, and roller means for enabling the shelf to run on the intermediate members and the intermediate members to run with respect to the frame;
- the improvement comprising(i) first roller means journalled at the front of the frame to support the intermediate member,(ii) second roller means journalled on the intermediate member and co-operating with a level track provided on or by the frame,(iii) third roller means journalled at or near the forward end of the intermediate member to support the shelf, and(iv) fourth roller means journalled at or near the rear of the shelf and co-operating with a level track provided on or by the intermediate member,the arrangement being such that, on pulling out the shelf, the latter shifts with respect to the intermediate members while being supported horizontally thereby, and the intermediate members shift with respect to the frame while being supported horizontally thereby.

Abstract
A shelf (17) on a frame (18,19) sits within a tray-like structure provided by an intermediate frame (8), while the latter is supported by rails (6) and rollers (7). When pushed back into the storage position, the shelf (17) is stopped by a bar on the frame (8), with the rollers (21) on the shelf (17) at the rear ends of slots (12) in side plates (9) of the frame (8). The intermediate frame (8) is arrested by the outer framework (1). To gain clear access, the shelf (17) is pulled out horizontally, and it can shift with respect to the intermediate frame (8) a distance corresponding to the length of the slots (12). When it reaches the limit of this travel, the frame (8) is entrained and continued pulling draws it out, running on the rollers (7) and (13). The limit of its travel is defined by stops but when achieved the shelf (17) is fully clear of the framework and thus fully accessible. To restore the storage position, the shelf is simply pushed in again.
