DESCRIPTION OF EMBODIMENTS

Referring to FIGS. 1 to 6, a carrier 1 for a paint tray according to an embodiment of the present invention comprises a coupler 3 for coupling to a paint tray and a lifting member 5 extending from the coupler. The coupler includes a coupling member 7 having a front face 9, a rear face 11, a top 13 and a bottom 15. In this embodiment, the front face 9 of the coupling member is shaped so that at least portions of the front face which are spaced apart between the top 13 and bottom 15 of the coupling member can engage the wall of a paint tray, as for example shown in FIGS. 5 and 6. The coupler 3 includes a base portion 17 which extends rearwardly of the coupling member 7 for supporting the paint tray carrier on a floor or other horizontal surface. The lifting member 5 comprises an arm 19 which extends upwardly from the base portion 17 and which is connected to the base portion to provide a gap 21 between the rear face 11 of the coupling member 7 and the arm 19, as shown in FIGS. 5 and 6. Advantageously, in one embodiment, the base portion of the carrier is adapted to support the carrier arm 19 in an upright position when detached from a tray and without other assistance to facilitate attachment of the carrier to a paint tray, and in particular to allow a user to set the carrier into an upright position before attaching it to a tray without having to hold the carrier either before or during its attachment to a tray. The base also assists in stabilizing the tray/carrier assembly, helps to prevent tipping of the tray and supports the weight of the carrier directly and independently of the tray.

In this embodiment, an upper portion 23 of the lifting arm 19 is angled to extend forward over a paint tray, when the carrier is attached thereto and includes an end portion 25 for supporting the handle 27 of a paint roller 29, as for example shown in FIGS. 3 and 4. In this embodiment, the end portion 25 has lower surfaces 31, 33 which extend either side of the arm 23 to enable the arm to be lifted by two fingers positioned below the end portion 25. A slot 33 is formed in the end portion for receiving a paint roller handle 27 to prevent sideways movement thereof.

FIGS. 3 to 6 illustrate how the same paint tray carrier according to an embodiment of the present invention can be attached to two different types of paint trays. In particular, FIGS. 3 and 5 show the carrier attached to one type of common paint tray which is generally moulded from a plastic material and FIGS. 4 and 6 show the carrier attached to a paint tray of a common, pressed metal type.

Referring to FIGS. 3 and 5, the first type of paint tray 41 comprises a container 43 having a paint well 45, a ramp 47 (which may include ribs, not shown) and an inner wall 49. The paint tray further includes an outer wall 51 which supports the container 41 and which is attached to the upper portion of the inner wall for example by a rim or web 53. A slot 55 (shown in FIG. 3) is formed in the lower part of the rear outer wall 57, and possibly also in the lower part of the front outer wall 59, for receiving fingers of a user so that a lower edge of the outer wall is manually accessible to a user when the paint tray is resting on a floor to facilitate lifting and moving the paint tray.

To attach the tray 41 to the carrier 1, the bottom edge 61 of the tray is simply raised above the level of the top 13 of the coupling member 7, the space 63 between the inner and outer walls 49, 57 of the tray is positioned over the coupling member 7 and the tray is then lowered over the coupling member so that the front face 9 of the coupling member engages the inner face 65 of the inner wall 49 and the rear face 11 of the coupling member 7 engages the inner face 67 of the outer wall 51 of the paint tray.

The coupling member is preferably adapted to engage both the inner and outer walls of the paint tray simultaneously and fit relatively snugly or tightly therebetween and to prevent any significant rotation of the paint tray about the coupling member due to its weight when the carrier is lifted. The coupling member 11 should also extend sufficiently into the space so that portions of the coupling member which engage the inner and outer walls of the tray are sufficiently spaced apart between the top and bottom of the tray to prevent significant rotation of the tray due its weight when the carrier is lifted.

The coupling member may be sized so that when inserted into the space, it moves the inner and outer walls of the container apart, at least slightly, so that the resiliency of the tray walls assist in retaining the coupling member within the space when the tray is lifted other than by means of the carrier, without the carrier falling out. The paint tray wall engaging surfaces of the coupling member may also be adapted to produce friction with the container walls, again to assist in retaining the coupling member within the space and to support the weight of the carrier. Although in one embodiment, the front and rear faces of the coupling member may be adapted to substantially conform with the profile of the inner faces of the inner and outer walls of a paint tray, in other embodiments, the coupling member may include protrusions, for example resilient protrusions for engaging with the inner faces of the inner and outer walls to allow the coupling member to conform to different shapes and profiles of inner and outer walls of different paint trays and different shaped gaps between the inner and outer walls.

Double-walled paint trays may have webs of material within the space between the inner and outer walls and which, for example, extend between the inner and outer walls thereby forming a bridge connecting the walls together for additional strength. Furthermore, paint trays may have other formations which also extend into the space and which potentially provide an obstruction to inserting the coupling member into the space. Embodiments of the coupling member may be adapted to avoid these webs or other protrusions by shaping the coupling member appropriately, and such shaping may for example include forming slots or recesses within the coupling member to accommodate the various protrusions.

The coupling member is preferably adapted so that when inserted into the space between the inner and outer walls of a paint tray to the extent necessary to properly secure the carrier to the tray, the lower surface or bottom 15 of the coupler lies substantially flush with floor engaging portions of the tray or extends below the tray to some degree so that, when in use, the carrier is independently supported by the floor.

In one embodiment, the upper surface 22 of the base 17 of the coupler may be positioned to engage the lower edge of the outer wall of the tray or so that the lower edge is near the upper surface so that the base can provide additional support for the tray at the lower edge of its outer wall.

Referring to FIGS. 4 and 6, the second type of paint tray 81 with which the carrier 1 may be used comprises a container 83 having a paint well 85, a ramp 87, a container wall 89 and a rim 91 extending outwardly from the upper edge of the container wall 89. The tray 81 also includes a foot or feet 93 positioned below the ramp 87 for supporting the front end of the tray and to keep the tray level when supported on a horizontal surface.

To attach the carrier 1 to the tray, the coupling member 11 of the carrier is positioned adjacent the wall 89 of the tray and so that the top 13 of the coupling member is positioned below the rim 91, as shown in FIG. 6. Thereafter, a clip or clamping member 10 is pushed downwards over the top of the container wall so that one jaw 12 of the clip engages the container wall and the second jaw 14 of the clip engages the rear surface 11 of the coupling member 7 to urge and retain the coupling member against the container wall.

The strength of the coupling between the tray and the coupling member will depend on the resiliency of the clip and also the extent to which the jaws of the clip extend over the wall of the tray and over the rear wall of the coupling member. In the present embodiment, the clip extends downwards over a substantial portion of the height of the tray wall and over a substantial portion of the height of the rear wall of the coupling member. However, in other embodiments, the jaws of the clip may extend downwards by a lesser or greater degree.

Advantageously, since the clip is free to move up and down by any required extent, not only is attachment of the carrier to the paint tray greatly facilitated over prior art arrangements, but the jaws of the clip can be relatively long thereby substantially increasing the strength of the coupling, again in comparison to prior art arrangements where the resiliency of the clip which is responsible for the coupling between the carrier and tray must be sufficiently flexible to allow the clip to be bent manually in order to connect the tray to the carrier.

In this embodiment, the top 13 of the coupling member can support the tray from the rim 91. However, in other embodiments the top of the coupling member need not engage the rim and the tray may be supported simply by virtue of friction between the tray wall and the coupling member when the wall and coupling member are forced together by means of a suitable retainer, for example, a clamping member or clip as shown for example, in FIGS. 2, 4 and 6. If necessary, the friction of the surface of the tray and/or coupling member may be enhanced by any suitable means, for example, by treating the surface with a suitable treatment or texturing the surface, for example, by knurling or otherwise providing surface structure.

It is to be noted in the embodiments shown in FIGS. 5 and 6, the lower portion of the coupling member 7 generally curves or extends forwards to conform with and engage at least a portion of the curved lower part of the container wall which adjoins the floor of the paint well 45, 85. This feature may assist in supporting the tray when lifted by the carrier.

As for the embodiment shown in FIG. 5, the coupler is preferably adapted so that it is coupable to the tray in such a manner that the base 15 of the carrier lies substantially flush with the floor engaging parts of the tray or extends below the floor engaging parts of the tray so that the carrier can be supported directly by a horizontal surface and independently of the tray. Advantageously, this helps to stabilize the carrier and tray when connected together and prevents the carrier from contributing to a moment of the combined carrier/tray assembly which would otherwise tend to tip the tray forwards towards the carrier.

Although in the embodiments described above, the carrier is shown connected to the rear end of the paint trays, it will be appreciated that the carrier may be connected to any other portion of the paint tray wall, for example, one of the side walls, or the front wall.

FIG. 7 shows an embodiment of a clamp member or clip 10 which includes a detent arrangement 16, 18 for locking the second jaw 14 of the clip to the coupling member 7. In this particular embodiment, the detent arrangement comprises a recess 16 formed in the rearward face 11 of the coupling member and a corresponding protrusion 18 protruding from the inner face of the second clip jaw 14. In other embodiments, the protrusion may be formed on the coupling member and the recess formed on the clip. However, this latter arrangement, in which the protrusion is formed on the coupling member, may interfere with the coupling member's ability to adapt to double walled paint trays, as shown in FIG. 5 in which the rear face engages with the outer tray wall. In other embodiments, any other form of suitable detent arrangement may be included or a detent arrangement may be omitted altogether.

The clip may be formed from any suitable material including metal, for example sheet metal of a suitable thickness and having the desirable resilience or from a plastics material, or from any other suitable material.

FIG. 8 shows a rear view of an embodiment of a carrier 1 and like features are designated by common reference numerals. The carrier further includes at least one holder 20, 22 supported by and extending from the carrier arm 5 and which may be adapted to support at least one of a paint can and a beverage container such as a cup, mug or flask. Advantageously, the base 15 of the carrier supports the weight of the container(s) independently of the tray.

The coupler and lifting member, e.g. the carrier arm may be formed of any suitable material or combination thereof, including plastics, metal or wood. In one embodiment, the lifting member may be arranged to swivel relative to the coupler so that any angled upper portion of the arm which for example provides a carrying handle or is used for supporting the handle of a paint roller can be rotated away from an overhanging position above the tray.

Modifications and changes to the embodiments described herein will be apparent to those skilled in the art.
