Definitions

  • This invention relates to pull-out shelf support systems. It is primarily concerned with such systems for use in an industrial context, for example in racking for stores, where hundreds of different items may be held, some of them heavy and awkward to handle.
  • the problem is that the shelf needs to be supported when drawn out, and in order to provide sufficient counteracting force to the tendency of the shelf to tip, it is usual for there to be a limit on the horizontal movement, leaving the rear portion of the shelf, perhaps up to one third of the total area, still within the fixed framing. Although this makes it better than fixed shelving, there are still access problems. It is desirable to have the shelf pulled out so that its total area is exposed.
  • Certain lightweight structures such as filing cabinets, have solved this problem by the use of an intermediate runner at each side which travels by means of ball bearings or rollers on rails fixed to the cabinet and which itself provides ball bearing or roller support for a track on the drawer to run on. As the drawer is pulled out, the runners move with it, but travel half the distance.
  • 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, characterised in that there are:
  • each track on the fixed frame comprises two horizontal rails one above the other.
  • the second roller means may then be a wheel which runs between them, sometimes bearing on the lower rail (when the shelf is pushed in) and sometimes on the underside of the upper rail (when the shelf has been pulled out a certain distance).
  • each intermediate member has its track provided by an elongate slot.
  • the fourth roller means may then be a wheel within the slot bearing on the bottom edge or the top edge depending on the balance of the shelf and how much it has been pulled out.
  • the intermediate members are not independent. They may form the sides of a frame underlying the shelf, and which therefore moves with the shelf when that is pulled out, although not to the same extent.
  • the intermediate members By selection of tolerances and the frictional characteristics of the various roller means it can be ensured that the shelf completes its travel before the intermediate members start to move, or vice versa. There may be situations where this is more desirable than having simultaneous movement.
  • a framework is constructed of metal angles and box sections to have uprights 1, horizontal members 2 and angled braces 3.
  • construction is conventional and will not be described in detail.
  • vertical dotted lines representing a possible fourth upright.
  • This specification is primarily concerned with single entry shelving 4 which can only be pulled out one way, to the right as seen in Figure 1.
  • double entry shelving is also possible, where a shelf 5 can be pulled out to one side or the other, as illustrated low down. For this, the extra upright may be needed.
  • a single entry shelf can only be pulled out so that about 60% of its plan area is exposed beyond the framework. This is indicated by the upper shelf 4.
  • the object here is to increase that to 100% as indicated by the lower shelf 4.
  • each upright 1 has a roller 7 journalled on the inside, slightly below the rails 6.
  • These rails and the rollers 7 support an intermediate frame 8 shown in Figures 2 and 3.
  • This is rectangular in plan and comprises flat vertical plates 9 at each side spanned at intervals by box section beams 10.
  • the plates 9 are substantially rectangular, their upper edges being well above the beams 10, and at the rear a flat bar 11 is welded between the plates 9 above the adjacent beam 10 to provide a stop.
  • Each side plate 9 has an elongate slot 12 with rounded ends extending lengthwise of it, starting a short distance from the rear end and terminating just beyond the mid point. To the rear of this slot 12, and centred below its lower edge, there is a roller 13 carried on the outside of the frame 8 by a short axle 14 extending through the plate and anchored in a block 15 secured to the front of the rear beam 10. Each roller 13 fits with a very small clearance between the associated rails 6 so that it either runs on the lower rail or engages the underside of the upper rail. At the forward end of the intermediate frame 8, the bottom edges of the side plates 9 bear on the rollers 7 fitted to the uprights 1.
  • the side plates 9 carry further rollers 16 on the inside, their uppermost segments being proud of the beams 10.
  • a shelf 17 is also basically a rectangular frame, having vertical rectangular side plates 18 spanned by beams 19. These support a rigid sheet 20 which provides the bearing surface of the shelf. Towards the rear of each plate 18 a roller 21 is journalled on the outside which engages in the associated slot 12 in similar fashion to the rollers 13 between the rails 6. The lower edge of each side plate 18 bears on the associated roller 16.
  • the shelf 17 sits within the tray-like structure provided by the intermediate frame 8, while the latter is supported by the rails 6 and the rollers 7.
  • the shelf 17 is stopped by the bar 11, with the rollers 21 at the rear ends of the slot 12.
  • the intermediate frame 8 is arrested by the framework.
  • 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.
  • 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 (not shown) but when achieved the shelf 17 is fully clear of the framework and thus fully accessible.
  • the shelf is simply pushed in again.
  • the same principles can apply, but of course the intermediate frame 8 and the shelf 17 will be symmetrical, with the slot 12 and the rollers 13 and 21 central, and extra rollers 7 and 16. It would be advisable to have a catch arrangement, releasable from either end, to hold the shelf centred and to prevent overshoot when being pushed back into the frame.
