GB2334880A - Lidded Bin - Google Patents

Abstract

A waste bin 1 is pivotally secured to a back plate 4 such that when a force is applied to a front panel 5 the bin is moved in a rearward direction and a flange 8c contacts part 2b of a lid 2 causing it to lift. Flange 8c is attached to the rear upper edge of the receptacle 1 and contacts portion 2b which depends downwardly from a generally horizontal portion 2a of the lid 2 at an angle of about 30‹. The angle at which portion 2b is arranged is such that relatively small rearward movement of the receptacle causes a large opening movement of the lid. Support lugs 11 are attached to the back plate 4 and support the bin by engaging a support band 10 in such a way as to allow the bin to tilt towards the back plate 4. The back plate 4 may be secured to a wall at just above knee level so that the knee of a user can be used to apply the necessary force to the front of the bin.

Description

LIDDED BIN The invention relates to lidded bins such as waste bins.

Waste bins with lids are widely used and are made in a wide variety of materials and in a wide variety of sizes. They are preferably used with bin liners which isolate the waste placed in the bin from the inner surface of the bin to reduce the amount of cleaning and sterilisation of the bin necessary. When it is desired to deposit waste material in the bin it is necessary first to raise the lid of the bin. This can be done by engaging the lid at a position spaced from a hinge with the hand of the user but it is more convenient and usually more hygienic to engage a foot pedal which through a lever linkage raises the lid. It is however not always convenient to operate a foot pedal particularly if the user is wearing soft soled shoes or open toed sandals.

It has also being proposed to mount an open-topped bin in an open sided housing, the bin being inserted through the open side, being biased to tilt so as normally to be wholly contained within the housing and being provided with a foot pedal whereby the bin can be tilted to cause a part of the bin to project from the housing thereby exposing the open top of the bin, the bin returning to a position within the housing when the foot pedal is released.

According to the invention in a lidded bin a hinged lid is provided over an open top receptacle, the bin being pivotally mounted and tiltable, by applying force to the front of the receptacle, to cause a portion of the receptacle to engage the hinged lid to raise the lid.

Preferably it is a rear upper edge of the receptacle which engages the hinged lid and particularly engages an angled portion of the lid which extends from a rearward edge of a horizontal portion of the lid downwardly to the hinge of the lid whereby a relatively small generally horizontal rearward movement of the rear upper edge of the receptacle causes such rear upper edge to abut the angled portion and produce a large angular, for example about 60 , opening movement of the lid.

Advantageously a back plate extends downwardly from the hinge, in use is secured flush to a wall of a building, has a support at its lower end to support the receptacle pivotally adjacent the lower end of the receptacle and has a pair of upwardly directed support members to support the receptacle adjacent the upper end of the receptacle in a manner to allow the receptacle to tilt towards the back plate when pressure is applied to the receptacle and allow the upper end of the receptacle to fall outwardly again away from the back plate when such pressure is released.

The receptacle can be provided with a bin liner, the upper edge of which is folded over the upper edge of the receptacle and turned downwardly.

The bin can be provided at floor level or any height thereabove but is advantageously provided just above floor level with the upper edge of the bin provided just above knee level so that a knee of the user can conveniently be used to apply the pressure to the front panel of the receptacle to cause the receptacle to tilt and open the lid.

Various different materials can be used for the various parts of the bin but preferably all parts of the bin are formed of stainless steel.

The invention is diagrammatically illustrated by way of example in the accompanying drawings in which: Figure 1 is a perspective view from one side the front and above of a lidded bin according to the invention with the lid in a closed position; Figure 2 is a side view corresponding to Figure 1; Figures 3 and 4 are respectively fragmentary views to a larger scale of the upper right-hand portion of Figures 1 and 2; and Figures 5 to 8 are views corresponding respectively to Figures 1 to 4 but with a lid of the bin moved to an open position.

Referring to the drawings a waste bin comprises a receptacle 1, a lid 2 for the receptacle 1, the lid 2 being mounted by a hinge 3 on a back plate 4. The lid 2 is moveable by pivoting about the hinge 3 between the closed position shown in Figures 1 to 4 and the open position shown in Figures 5 to 8, the movement of the lid between the closed and open positions comprising movement through about 60".

The receptacle 1 has an open top, a front wall 5, angled fillet walls 6 at either side of the front wall 5, side walls 7, a rear wall 8 and a bottom wall 9. A downwardly projecting flange 8a of the rear wall 8 extends below the bottom wall 9 and is supported in use by an upturned flange 4a at the bottom of the back plate 4.

At the upper end of the rear wall 8 there is a rearwardly extending projection comprising a horizontal flange 8b and at the free edge thereof a downwardly depending vertical flange 8c.

Close to the upper end of the receptacle 1 a support band 10 is secured, which support band 10 lies closely against the walls 5, 6 and 8 but is spaced sidewardly from the sidewalls 7 leaving at each side of the receptacle 1 a space between the support band 10 and the respective sidewall 7, into which space projects an upwardly extending lug 11 of a support bar 12 which extends horizontally across the back plate 4 and has forwardly projecting portions 13 which support the lugs 11.

A forward portion 2a of the lid 2 of similar shape in plan view as the receptacle 1 and is substantially horizontal in the closed position of Figures 1 to 4.

It is rigidly coupled at the rear edge thereof to an angled panel 2b which slopes downwardly at an angle of approximately 30O from the rear edge of the horizontal portion 2a of the lid to the hinge 3. Leaves 3a and 3b of the hinge 3 are secured respectively to the angled panel 2b and to the back plate 4.

In use the back plate 4 is secured, advantageously by screws (not shown) passing through keyhole shaped apertures (also not shown) in the back plate 4, to a vertical support surface such as a wall with the lower end of the receptacle 1 just above floor level. The back plate 4 is thus substantially vertical. The lid 2 is raised to the position of Figures 5 to 8 and the receptacle 1 is hung on the back plate 4 by engaging the flange 8a in the recess formed by the upturned flange 4a of the back plate 4 simultaneously with engaging the lugs 11 inside the support band 10. When released the receptacle 1 hangs in the position shown in Figures 1 and 2 and the lid 2 can fall down and close the upper end of the receptacle 1. If a force is applied to the front panel 5, preferably just below the band 10 and by a knee of the user, the receptacle 1 will pivot about the bottom edge of the flange 8a so that the upper end of the rear wall 8 moves towards the back plate 4. As it does so the edge formed by the junction of the horizontal flange 8b and the downwardly depending flange 8c abuts the angled panel 2b of the lid 2 and pushes the angled panel 2b into a vertical orientation. This causes the lid 2 to pivot about the hinge 3 through approximately 60 to the open position of Figures 5 to 8. With the lid 2 so opened material can be dropped into the open top of the receptacle 1. Removing the force applied by the knee to the front panel 5 permits the receptacle to pivot outwardly about the lower edge of the flange 8a back to the position of Figures 1 to 4, thereby removing the force applied to raise the lid 2 and allowing the lid 2 to pivot, under its own weight, back to the closed position of Figures 1 to 4.
