The lid is removed by raising the lid relative to the housing in a vertical direction in any orientation other than in the fully open position, and the lid can be replaced by lowering the lid in any orientation other than the fully open position. <IMAGE>
Description
"IMPROVEMENTS IN OR RELATING TO COVER ARRANGEMENTS".
The present invention relates to cover arrangements and to a method of locating a cover member on a cover support and Is particularly, although not exclusively appl icable to cover members for waste disposal arrangements.
PCT Publication No. 89/02863 and U.S. Patent No.
4 282 983 both disclose lids which are detachably connected to a support and which can be held in an open position. However, both of the prior lid mounting arrangements rely upon there being a snap fit between the co-operating parts with the snap fit also providing the support for the lid. The snap fit arrangement may be prone to fatigue and is complicated in structure.
Furthermore, in order to fit and remove the iids accurate a I i gnment and considerable force is required thus subJectlng the parts to undue stress and requiring a user to ensure that the parts are accurately maligned prior to connection.
According to one aspect of the present invention a cover arrangement comprises a cover member and a cover support, the cover member being pivotal on the support between a closed position in which an opening is substantlally covered by the cover member and an open positlon, the cover member and the cover support including a first set of surfaces arranged to co-operate with each other in the open position to allow the cover member to remain in the open position under a force exerted by the weight of the cover member and to resist pivotal movement of the cover member from the open position in the opposite pivotal direction to that in which It would move to the closed position, and a second set of co-operating surfaces different from the first set arranged to support the cover member on the cover support during pivotal movement.
The cover member may be removable from the cover support, and the cover member may be returnable, when removed, to a position In which It Is able to co-operate with the support under a force exerted by the weight of the cover member.
According to another aspect of the present invention a cover arrangement comprises a cover member and a cover support, the cover member being pivotal on the support between a closed position, In which an opening is substantially covered by the cover member, and an open position, the cover member being arranged to cooperate with the support in the open position to allow the cover member to remain in the open position under a force exerted by the weight of the cover member and to resist pivotal movement of the cover member from the open position in the opposite pivotal direction to that in which it would move to the closed position, the cover member being removable from the cover support, and the cover member being returnable, when removed, to a position in which it is able to co-operate with the support under a force exerted by the weight of the cover member.
The cover member and the cover support may
Include a first set of surfaces arranged to co-operate with each other in the open position to allow the cover member to remain in the open position under a force exerted by the weight of the cover member and to resist pivotal movement of the cover member from the open position in the opposite pivotal direction to that in which it would move to the closed position, and a second set of co-operating surfaces different from the first set arranged to support the cover member on the cover support during pivotal movement.
At one axial location the second set of cooperating surfaces may Include a single co-operating surface from each of the cover member and the cover support.
A surface of the cover member from the second set of co-operating surfaces may comprise an edge of the cover member.
The second set of co-operating surfaces may be located at a different axial location from the first set of co-operating surfaces.
A plurality of second sets of co-operating surfaces may be provided, and each of those sets may be axially spaced from each other.
The surface of the cover support of the second set of co-operating surfaces may support the cover member in the open position and during initial movement away from the open position.
The first set of co-operating surfaces may comprise two spaced surfaces on each of the cover member and the cover support. One of the co-operating spaced surfaces of the cover support may include a downwardly facing surface and, alternatively or additionally, one of the co-operating surfaces of the cover member may include an upwardly facing surface.
The first set of co-operating surfaces of the cover support may be provided along an elongate opening of the cover support.
The cover support and the cover member may cooperate to resist axial movement In at least one direction of the cover member relative to the cover support, and preferably In both direction and, alternatively or additionally, the co-operation of the cover support and the cover member to resist axial movement may be arranged to occur at two spaced locations.
According to another aspect of the present
Invention In a method of locating a cover member on a cover support in which, when located, the cover member is pivotal on the support between a closed position, in which an opening is substantially covered by the cover member, and an open position, the cover member being arranged to co-operate with the support in the open position to allow the cover member to remain in the open position under a force exerted by the weight of the cover member and to resist pivotal movement of the cover member from the open position In the opposite pivotal direction to that in which it would move to the closed position, the method comprises locating the cover support under a force exerted by the weight of the cover member.
The method may comprise locating the cover member on the cover support whereby, when the cover support is located, the cover support Is In the closed position.
Alternatively or additionally, the method may comprise locating the cover member on the cover support when the cover member is In the open position, or in any position between the open and closed positions.
The present invention also Includes a method of locating a cover member on a cover support to comprise a cover arrangement as herein referred to.
The present invention may be be carrled Into practice In varlous ways, but one embodiment will now be described by way of example and with reference to the accompanying drawings, In which:
Flgure 1 Is a plan view of a waste outlet housing 10;
Figure 2 is a plan view of the housing 10 with a lid 12 shown covering an outlet opening 14 (shown in
Figure 1) of the housing 10;
Figure 3 is a side sectional view of part of the lid and housing taken along the line III-lll of Figure 2 with the lid in a closed position;
Figure 3A is a view similar to Figure 3 with the lid shown in an open position;
Flgure 4 is a side sectional view of part of the lid and housing taken along the line IV-lV of Figure 2 with the lid In a closed position; ;
Figure 4A is a view similar to Figure 4 with the lid In an open position, and Flgure 4B Is a view similar to Flgures 4 and 4A with the lid shown in one orientation from which the lid may be removed from the housing.
The housing 10 comprises a surrounding ridge 16 which is arranged to be located on, or set flush in a worksurface (not shown) in a kitchen. A depressed flat surface 18 Is located inwardly of the rldge 16 and an opening 20 on the Inwardly facing surface of the surface 18 leads down, through the worksurface, to a waste container (not shown) located beneath the worksurface.
An opening 22 Is located along part of the ridge 16 and the surface 18 In the region of a common extent.
As shown In Figures 2, 3 and 4, the lid 12 is arranged, In the closed position Illustrated, to rest on the surface 18 such that the upwardly facing surface 24 of the lid is against and generally flush with the ridge 16 such that the opening 14 Is concealed.
The lid can be moved from the closed position shown in Figures 2, 3 and 4 to the position shown In
Figures 3A and 3B in which access to the opening 14 Is gained and rubbish can be pushed over Into, or thrown through the opening to the waste container beneath.
In order to move the lid from the closed to the open position the rim of the lid is accessed from the open side of the housing to that on which the opening 22 is located by an operative moving their fingers Into a recess 26 formed by the rldge being spaced from the lid.
The side of the lid which has been accessed Is then raised and the lid pivots in an anti-clockwise direction from the view shown In Figure 3 to that shown In Figure 3A with the end 28 of the lid sliding over the upwardly facing surface 30 of the ridge .16. That sliding movement between the lid and housing occurs at both ends of the opening 22.
When the lid is in the open position shown in Flgure 3A, downwards movement of the lid is prevented by the abutment of the end 28 of the lid with the upwardly facing surface 30 of the housing.
In the open position shown in Flgure 4A, further clockwise pivotal movement of the lid is resisted by the surface 24 of the lid (which faces upwardly in the closed position) engaging with one side 32 of the opening 22 and by engagement of a rim 34 of the lid (which faces downwardly in the closed position) with an outwardly extending rlb 36 on the opposed side of the opening 24.
The lid 12 Includes a pair of spaced downwardly extending quadrant flanges 38 which are each located in enlarged slots 40 extending transversely from either end of the opening 22. The flanges 38 co-operate with the portion of the housing defining the slots 40 to restrict relative movement of the lid and housing in the direction of the axis of pivotal movement of the lid from the closed to the open position. The flanges 38 further cooperate with the portlon of the housing defining the slots 40 to resist movement of the lid away from the pivotal axis of the lid In the direction in which the lid extends during approximately the first 300 of pivotal movement of the lid from the closed position.
The lid can be quickly and conveniently removed from the housing, for instance for cleaning of those parts by raising the lid in a vertical direction in any orIentatIon other than in the fully open position shown in Figures 3A and 4A, or lowering the lid in any orientation other than the fully open position. In particular, the lid can be slid along the worksurface over the ridge 16, with the surface 24 of the lid facing upwardly until the quadrant flanges 38 drop Into the slots 40. Furthermore, the constructlon of the cooperating parts of the lid and housing is such that the parts cannot be placed In partlal co-operatlon and thus the parts are not prone to being subjected to undue stresses because of incorrect alignment.
In the Illustrated embodiment, the lid may not necessarily be removable from the open position illustrated in Flgures 3A and 4A by merely the raising of the lid because of the abutment of the rim 34 of the lid with the rib 36; it may be necessary to pivot the lid slightly towards the closed position before the lid can be raised and removed. However, In an alternative embodiment (not shown) the rlm 34 or rib 36 may be omitted with the lid being able to rest in the open position in which case the I id can be raised to be removed from the fully open position.
