Abstract
A wheeled support is described having a frame comprising four hollow arms (1) moulded from plastics material, arranged in the form of a cross. Each arm (1) carries an extension (2) slidably located in the hollow arm in a radial direction to adjust the length of the arm. Each arm (1) has a longitudinal slot (3) and carries a stop (4) at its outer free end with grooves (5) on its inner face to grip a container placed on the support. Located in a drilled hole (6) in the stop is a castor (7) having a rod (8) which locks in the hole by a spring circlip (9). A ratchet means (12) is provided between the extensions (2) and the arms (1) to incrementally adjust the extension means relative to the arms. The adjusted extensions (2) may be optionally locked relative to the arms (1) by screw-bolts (10) and wing-nuts (11).
Description
93/129~ ~ 7 ~ PCT/GB92/02372 A N~ELgD S~PPORT
This invention relates to a wheeled 8upport and more particularly to a wheeled 8upport for containers.
In medi~l or other clinical establishments where mater~ have to be di~posed of in a container it has S hitherto been the practice to walk to and from the container from the work location or to move the container to the po~ition at which the work is carried out. However if the per~on i~ constantly moving from one work loc~tion to ~nother the container has to be repeatedly moved to lQ avoid unnece~sary ~ourneys to and from the container.
Another disadvantage arises where the person i~ required to wear ~terile gloves and has to handle the container to move it from one work location to another. The alternative was to ~lide it across the floor with the lS person's foot. There i8 also a requirement for use of such wheeled supports in domestic or industrial applications.
An 8im of the present invention is to overcome the above problem ~nd di~advant~ges ~nd provide a wheeled support to carry existing container~ having a wide variety of outside sh~pes and sizes ~nd to mske them re~dily W093/129~ 21 ~ 5 (3 ~ ~ PCT/GB92/0237~
tran~portable.
According to the present invention there is provided a wheeled support comprising a frame having at least three radial arms with a wheel at or near the end of each arm wherein the arms are radially adjustable by ratchet means to receive and ~upport the base of a container.
Preferably, the frame has four radial arms, each arm having an extension slideable relative to the arm and locked thereto, the free end of the -exten~ion carrying a wheel or caster.
Conveniently, the wheeled support frame is made of a rigid plastics material.
The extensions are preferably adjustably 15 connected to the radial arms by ratchet means on the radial arms which engage ratchet pawls formed in the extensions to increment the movement of the extensions relati~e to the radial arms.
The extensions are preferably locked relative to 20 the radial arm~ by a screw-threaded wing-nut and a bolt pas~ing through a slot in the radial arm and/or extension.
In one preferred construction the frame is made from two members connected at their mid-points by a wing-nut and bolt.

According to the present invention there is provided a wheeled support comprising a frame having at least three radial arms with a wheel at or near the end of each arm wherein the arms are radially adjustable by ratchet means to receive and ~upport the base of a container.
Preferably, the frame has four radial arms, each arm having an extension slideable relative to the arm and locked thereto, the free end of the -exten~ion carrying a wheel or caster.
Conveniently, the wheeled support frame is made of a rigid plastics material.
The extensions are preferably adjustably 15 connected to the radial arms by ratchet means on the radial arms which engage ratchet pawls formed in the extensions to increment the movement of the extensions relati~e to the radial arms.
The extensions are preferably locked relative to 20 the radial arm~ by a screw-threaded wing-nut and a bolt pas~ing through a slot in the radial arm and/or extension.
In one preferred construction the frame is made from two members connected at their mid-points by a wing-nut and bolt.
2 An embodiment of tho wheeled support according to the invention will now be deRcribed by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a wheeled 30 support, and Figure 2 is a fragmentary detail o~ a support arm and extension, and Figure 3 is a modified construction of the wheeled support.
The wheeled support comprises four hollow arms 1 which are arrangsd in the form of a cro~ and ar~ moulded from a rigid pla~t$cs material. Each arm 1 carries an 2 1 h- ~ (3 7 Q
'~93/129~ PCT/GB92/02372 extension 2 located in the hollow arm and slideable in a radial direction to ad~ust the length of the arm. The arm has a longitudinal slot 3 and carries a stop 4 at its outer free end with grooves S on its inner face to grip 5 a container placed on the wheeled support. Located in a drilled hole 6 in the stop is a caster ~ which has a rod 8 which locks in the hole 6 by a spring circlip 9.
Each arm is formed with ratchet means 12 internally of the hollow arm 1 (only one arm, is shown in lO fragmentary cross-section) which engage corresponding ratchet pawls 13 formed in the free end of the extension 2. The end of the slot 3 in the extension 2 has bifurcated resilient arms urging the ratchet pawls 13 into engagement with the ratchet means 12 internally formed in lS the arm l. The four extensions can be incrementally ad~usted by sliding them into or out of the arms l. This will enable each of the four arms l to be ad~usted to the same length depending upon the number of clicks indicated by the ratchst means.
In a modified construction shown in Figures 2 and 3, like parts have the same reference numerals as in Figure l. The extensions 2 may be locked in their ad~usted position by 8 screw-threaded bolt lO which passes through a hole in each arm reRpectively and the slot 3 to 25 be secured by a wing-nut ll.
Although the support frame has been described as having four arms it may have only three arms. The arms be ad~ustable in length to accommodate containers having different outside shape~ and sizes such as circular, oval 30 ~hape, rectangular, square or triangular.
In use the extensions are pulled out and the container placed with its centre directly over the point at which the arms ~oin. The e~ten8ion8 are then pushed inwards under control of the ratchet me~ns until the 35 grooved faces of the stops 4 engage the side walls at the base of the container gripping it firmly, the arms are then locked in position. The container c~n thus be pushed WO93/129~ PCT/GB92/0237?-`
212~870 4 acros~ a floor or other surface smoothly on its wheels or casters.
In an alternative construction the arms l can be made from two members connected at their mid-points by a 5 wing-nut and bolt to form a cross. This facilitates the dismantling and packing of the wh~eled support by removing ~he wheeled casters and unscrewing the wing-nut and bolt connecting the two members and placing the members side by side.
It will be appreciated that the wheeled support is light weight and is made of a washable plastics material which can be readily washed and sterilized as may be xequired when used in sterile environments such as hospitals or other medical establishments.
lS The wheeled support is of robust construction and ic ~trong enough to support containers having relatively heavy contents such as sand used in fire safety equipment.
The container and sand may be wheeled across the floor instead of having to carry it over a long distance.
The wheeled support has a wide variety of domestic and industrial uses, for example, with garden tubs, tool chests, buckets or other containers. It is particularly u~eful by the elderly or infirm who have bad backs and find it difficult to bend and left the 25 container.
