DESCRIPTION:
BRIEF SUMMARY
This invention relates to refuse containers, e.g. litter bins or household dustbins.
It is known to line such a container with a disposable bag which is held open by stretching its mouth over an upper edge of the container. This can be difficult to achieve manually and may result in an untidy appearance of the bin if the overlap is too great. The bag is also prone to detachment from the container edge resulting in penetration of refuse between the bag and the container.
It is also known to suspend the bag freely from a fixed frame which provides an edge over which the mouth of the bag is turned. In this case slippage of the bag may result in spillage of refuse.
It is an object of the present invention to provide a refuse container in which the aforementioned disadvantages are obviated or mitigated.
According to a first aspect of the present invention there is provided a refuse container comprising a hollow body with an upper access opening closed by a displaceable cover, and a bag suspension frame carried by a body wall movable between a closed position in which the frame is positioned below the access opening and an open position in which the frame is exposed for bag replacement, said frame having a movable frame element projecting away from the wall and the body having internal surfaces for deflecting said frame element upwardly during closing movement and downwardly during opening movement of the wall.
According to a second aspect of the present invention there is provided a refuse container comprising a supporting frame including frame elements engageable with the mouth of a disposable bag and movable relatively apart into a stable over-centre position in which the bag mouth is held open in use.
The invention will now be further described by way of example only with reference to the accompanying drawings, in which:
FIG. 1 is a partly cut-away side view of a refuse container with a refuse bag held in position by one embodiment of supporting frame in accordance with the invention,
FIG. 1A is a sectional view on line 1A--1A of FIG. 2.
FIG. 1B is a side view of the supporting frame.
FIG. 2 is a corresponding plan view:
FIG. 2A is a detail showing a rivet around which the supporting frame pivots.
FIG. 2B further illustrates the supporting frame and its capability to pivot.
FIGS. 3 and 4 are diagrams illustrating the mode of operation of the supporting frame;
FIG. 5 is a perspective view from the front and one side of a swing-top refuse container with an opening front carrying a second embodiment of supporting frame in accordance with the invention,
FIG. 5A is a partial side view of the swing top refuse container of FIG. 5, and
FIG. 6 is a scrap view from the front and other side of FIG. 5 looking upwardly into the body of the container.
Referring now to FIGS. 1 to 4, a refuse container 1 (of the kind intended to be mounted on a street cleaners' hand cart adjacent a like container) is of generally square shape in plan with a downwardly tapering body 2 integrally moulded in synthetic plastics material. The open top of the container 1 is closed by a lid (not shown) resting on the upper edge 3. Side handles 4 are provided at opposite sides of the container but form no part of the present invention. Slightly below the edge 3 is an integrally moulded internal ledge 5 on which rests a supporting frame 6 indicated in position in chain-dot line in FIGS. 1 and 2 and more clearly illustrated in the insets to those Figures. The edge 3 and ledge 5 may have their bag-contacting surfaces (see below) made of a resilient or high friction material. The supporting frame 6 is of generally square shape conforming to, but slightly smaller than, the edge 3. As seen in the right-hand inset to FIG. 1 there is a slight clearance between the frame 6 and the edge 3. The frame 6 is made in two symmetrical halves of galvanised steel which are connected to each other and to the edge 3 by rivets 7 as more clearly shown in the lower inset to FIG. 2 which shows the overlapping ends of the halves of the frame 6. The rivets 7 permit relative
