Abstract

An article such as a rubbish container for mounting on a support surface such as a wall. The article has a back plate 1 for fixing to the support surface, and a body 2 for mounting on the back plate. The body supports an element, such as a pivotal lid 3, which is movable relative thereto from a normal position to a displaced position, and the back plate and body define formations e.g. hooks 5 and body apertures which can be interengaged by a predetermined movement of the body relative to the back plate so as to secure the body to the back plate. The element and back plate define formations 6, 5 which when the element is in the normal position (Figure 6) interengage to prevent disengagement of the body from the back plate and when the element is in the displaced position (Figures 1, 3) permit disengagement. <IMAGE>

Description

SPECIFICATION Wall-mounted article The present invention relates to an article for mounting on a support surface such as a wall.

Wall-mounted articles are required for a variety of purposes. For example, there is a widespread use of wall-mounted containers for receiving wastepaper or other rubbish and for dispensing materials such as papertowels, soap and the like. It is highly desirable if such containers can be easily lifted off the wall for emptying, filling or the like. It is however necessary to prevent such containers being accidentally knocked offthe wall or deliberately removed without authorisation by, for example, vandals. It is known to provide such containers with a back plate which is permanently secured to a wall and to fix the container to the back plate by for example screws, locking mechanisms orthe like.Such fixing arrangements as have been proposed are not altogether satisfactory however as they generally result in a relatively expensive structure and are either not sufficiently secure against unauthorised removal or are more difficult than isdesirablefor authorised removal.

It is an object of the present invention to obviate or mitigatethe above problems.

According to the present invention, there is provided an article for mounting on a support surface, comprising a back plate for fixing to the support surface, and a bodyfor mounting on the back plate, the body supporting an elementwhich is movable relative thereto from a normal position to a displaced position, the back plate and body defining formations which can be interengaged buy a predetermined movement of the body relative to the back plate so as to secure the body to the back plate, and the element and back plate defining formations which when the element is in the said normal position interengageto prevent disengagement of the body from the back plate and when the element is in the said displaced position are disengaged so as to permit said disengagement.

The article may be a wall-mounted container in which the movable element defines a pivotal lid.

When the lid is closed the container body cannot be released from the back plate. On the other hand when the lid is open the container body can be lifted from the back plate. A lock may be provided to secure the lid in the normal closed position to thereby prevent unauthorised removal of the container body. If the container is to be used to receive rubbish or the like an opening in the body may be provided to enable rubbish to be deposited in the container. The lockable lid would only be opened when it is desired to liftthecontainer bodyoffthe back plateto enable the container to be emptied.

An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figures ito 6schematically illustratetheway in which the back plate, body and a pivotal lid interengage in one embodiment ofthe invention; Figure 7illustratesthe structure of a second embodiment of the invention; and Figures8and 9respectively illustrate details ofthe lid hinge and lid hinge and lid lockofthe embodiment of Figure 7.

Referring to Figures 1 to 6, the illustrated embodiment comprises a back plate 1, a container body 2 and a movable element or lid 3. The lid 3 is secured to the body 2 by a hinge 4. The back plate 1 supports a series of hooks 5, for example three in number, and the body 2 defines apertures through which the hooks 5 can be inserted. The lid 3 supports a downwardly extending L-shaped element 6 which is intended to engage behind one of the hooks 5.

As shown in Figure 1 ,the back plate 1 is initially secured by for example screws to a support surface, for example a wall. The back plate is thus a permanentfixture. The body is then offered up to the back plate in the position shown in Figure 1 and then pushed towards the back plate as shown in Figures 2 and 3 in the direction of the arrows so that the hooks 5 pass into the interior of the container body 2 through the appropriately positioned apertures therein. The container body is then allowed to drop downwards in the direction of the arrow shown in Figure 4 so thatthe hooks engages behind the edges ofthe aperture in the body th rough which they have been inserted.As shown in Figures 5 and 6the lid 3 is then dropped down so that the element 6 engages beneath the uppermost hook 5.

When the container lid is closed as shown in Figure 6 any attempt to remove the container from the back plate is prevented as the container body cannot be moved upwards due to the interengagement of the uppermost hook on the back plate and the element depending from the lid. The only way the container body can be lifted from the back plate is byfirst opening the lid and then moving the container body relative to the back plate in the appropriate manner.

Thusthe body cannot be pulled off the back plate accidentally or intentionally unless the lid has been opened.

The lid may be locked in the position shown in Figure 6 by a simple locking mechanism (notshown) and when so locked the container body cannot be removed from the back plate without either smashing the lid or unlocking the lid.

Referring now to Figures 7 to 9, a second embodiment of the invention is illustrated in greater detail. The same reference numerals are used for equivalent components as those used in Figures 1 to 6. The back plate 1, container 2 and lid 3 are all fabricated from, for example, galvanised steel. The hooks 5 are welded to the back plate 1 and the depending element 6 is welded to the lid 3. A location bracket 7 is also welded to the back plate 1, the location bracket supporting a bin (notshown)which in use is inserted within the container body.

The detail of the structure of the container in the vicinity of the lid hinge 4 is shown in Figure8.

Figure9 illustrates an arrangementfor locking the lid 3 in the closed position. A key operated lock 8 can be actuated to control the position of a locking bar 9.

In the position shown in Figure 9 the locking bar9 engages behind a bracket 10 welded to the lid 3so as to prevent the lid 3 being lifted up. The locking bar9 can howeverbeswung awayfromengagementwith the bracket 10 so asto enable the lid to be opened.

Claims

1. An article for mounting on a supportsurface, comprising a back plate forfixing to the support surface, and a body for mounting on the back plate, the body supporting an element which is movable relativetheretofrom a normal position to a displaced position, the back plate and body defining formations which can be interengaged buy a predetermined movement of the body relative to the back plate so as to secure the body to the back plate, and the element and back plate defining formations which when the element is in the said normal position interengageto prevent disengagement of the body from the back plate and when the element is in the said displaced position are disengaged so asto permit said disengagement.

2. An article according to claim 1,whereinthe movable element is a pivotal lid and the body is a container, the container body being movablefrom the back plate onlywhen the lid is in an open position.

3. An article according to claim 2, wherein a lock is provided to secure the lid in a closed position to thereby prevent unauthorised removal ofthe container body.

4. An articleaccordingto claim 3,wherein an opening is provided in the body to enable rubbish to be deposited in the container when the lid is in the closed position.

5. An article for mounting on a supportsurface substantially as hereinbefore described with referenceto the accompanying drawings.
