DESCRIPTION:
BRIEF SUMMARY
The present invention relates to implements for supporting paint-roller sleeves for rotation, particularly but not exclusively for cleaning.
It is known to clean paint-roller sleeves by soaking them in a suitable solvent and rotating them about their longitudinal axes to expel the paint and solvent therefrom centrifugally. Various implements are known for supporting such sleeves for rotation, either on or detached from their rollers, the rotation being effected either manually or by a motor, for example by the motor of an electric drill. Such implements are not, however, widely available.
A complicating factor in the production of such implements lies in the fact that paint rollers are available in different sizes. The implements themselves must, therefore, either be made in different sizes to accommodate different rollers or roller sleeves, or they must be adaptable in some way to accommodate rollers or sleeves of different sizes. The provision of such different or adaptable implements adds to the manufacturing costs.
The object of the present invention is to provide an implement which is convenient to use and adaptable to support different sized roller sleeves for rotation but which can be manufactured more cheaply than prior art such implements so that it may be made more widely available.
Accordingly, the present invention provides an implement for supporting selectively each of at least two roller sleeves of different internal diameters for rotation about their axes, the implement comprising an elongate support adapted to extend through each sleeve and having support means for supporting the smaller-diameter sleeve at two longitudinally-spaced positions, the elongate support also being adapted or adaptable to support the larger-diameter sleeve at a first position and the implement further including adapter means engageable with the support means for the smaller-diameter sleeve and adapted, when so engaged, to support the larger-diameter sleeve at a second position spaced from the first position.
The invention provides a very simple way of adapting a support to carry different sized sleeves and, in a preferred embodiment, the adaptor means and at least the part of the elongate support carrying the support means for the sleeves may be manufactured very cheaply by moulding from plastics material. Although the invention has been devised particularly with a view to providing an implement for facilitating the cleaning of paint-roller sleeves it could alternatively be used as part of a paint-roller body for supporting respective sleeves for use in painting and decorating. In this latter case the sleeve support means would support the respective sleeve for rotation relative to the elongate body, or a shaft extending therethrough, and the implement would, in most cases have, a handgrip at one end. This use could reduce manufacturing costs for manufacturers currently making different sized rollers for different markets or could enable a purchaser to buy a single roller body and equip it with different sleeves for different painting tasks.
In the preferred form of the implement, however, to which reference will be made below and in which its intended use is for cleaning roller sleeves, the support means are adapted to connect a roller sleeve supported thereby to the elongate support for rotation therewith and the elongate support is adapted at one end for engagement with a drive for rotating it about its axis.
The implement of the invention could readily be adapted to support more than two different-diameter paint-roller sleeves by the provision of additional support means but two particular sizes of rollers are most commonly available on the market and the implement is preferably arranged to support these two sleeve sizes.
In practice the implement of the invention is adapted to support each sleeve to be carried thereby at or adjacent each end in order to minimise any wobbling of the sleeve on the support during rotation. The support means may be adapted to grip the sleeve ends but may simply comprise or includ
