This patent application is a National Phase Concerning a Filing Under 35 U.S.C. 371, claiming the benefit of priority of PCT/GB00/03195, filed Aug. 18, 2000, which claims the benefit of priority of Great Britain Application Serial No. 9919420.1, filed Aug. 18, 1999, all of which are incorporated herein by reference.


FIELD OF THE INVENTION
The invention relates to container moving apparatus and especially, but not limited to, apparatus for moving containers containing fluids, for example beer barrels or gas cylinders.
BACKGROUND TO THE INVENTION
Containers containing fluids, for example beer barrels, gas cylinders, chemical drums, oil drums and fluid filled plastic containers are heavy and difficult to move. This is especially apparent for containers having a volume of 5 gallons and upwards. The barrels can simply be pushed and rolled along the ground. However, with these methods the barrels are generally out of control if being pushed down a decline and are therefore dangerous. In addition, the barrels are difficult to push up an incline and are also at risk of rolling back down the incline. Furthermore, if the barrels are manually manoeuvred then this requires the person to bend over in order to push the barrels. This puts the person at risk from injury and puts a high strain on the back of the individual. Any resultant back pain can result in time off work for the individual, and, therefore, puts a burden on the employer.
A prior art method comprises a trolley having a support section located between two wheels and a handle. The barrel is placed on the support section and the support section is tilted using the handle and the barrel an then be manoeuvred. One problem with such trolleys is that the wheels are generally small which makes the trolley difficult to manoeuvre upstairs or downstairs. In addition, the barrel is at risk of falling off the support section when manoeuvring down a decline or downstairs. With such trolleys the barrel travels in front of the individual. At sharp corners there is a risk of a collision since the individual cannot see around the corner prior to the barrel being pushed in front of the corner. The only solution is for the individual to stop pushing the trolley and firstly check for hazards around the corner.
It is an aim of the present invention to overcome at least one problem associated with the prior art whether referred to herein or otherwise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIGS. 1 and 2, beer barrel moving apparatus 10 has a frame comprising two side members 12, 14 which are connected at an upper location by a handle section 16. The side members 12, 14 are connected at a lower position by a reinforcement member 18.
The side members 12 and 14, handle section 16 and reinforcement member 18 all comprise tubular or box sections of aluminium. The handle section 16 and the reinforcement member 18 are both telescopic. The handle section 16 has two outer tube sections 11, 13 each being connected to one side member 12, 14 respectively. An inner tube section 15 having a smaller cross section is located inside the two outer sections 11, 13. Similarly, the reinforcement member 18 has two outer tube sections 17, 19 each being connected to one side member 12, 14 respectively. An inner tube section 21 having a smaller cross section is located inside the two outer sections 17, 19. This arrangement enables the length of the handle section 16 and the length of reinforcement member 18 to be adjusted by sliding the outer sections over the inner sections.
Each side member has a clamping member 20, 22 secured at a lower position. The clamping members 20, 22 are secured to the side members 12, 14 through roller bearings 24, 26. The bearings 24, 26 enable the clamping members 20, 22 to rotate relative to the side members 12, 14.
The side members 12, 14 are also connected by a flexible member 28. The flexible member 28 may be a section of webbing. The webbing 28 has a ratchet mechanism 30 located thereon.
The ratchet mechanism 30 enables the length of the webbing to be adjusted. By using the ratchet mechanism 30 to decrease the length of the webbing 28, the side members 12, 14 and the clamping members 20, 22 are moved towards each other and the lengths of the handle section 16 and the reinforcement member 18 are shortened.
As shown in FIGS. 3 and 4 a beer barrel 32 can be clamped between the two clamping members 20, 22. Once the beer barrel 32 is clamped by the clamping members 20, 22, the beer barrel 32 is able to rotate relative to the frame 10 as a result of the roller bearings 24, 26.
The barrel 32 is secured to the frame 10 by firstly spacing the clamping members 20, 22 by a distance greater than the length of the barrel 32. The clamping members are then positioned within the end annular flanges 34 of the barrel. The ratchet mechanism 30 is operated to reduce the length of the webbing 28. The axes of the clamping members 20, 22 are aligned with the central axis of the barrel 32. This subsequently results in a smooth rolling action of the barrel relative to the frame 10.
The reduction of the length of the webbing 28 urges the side members 12, 14 towards each other. This causes the handle section 16 and reinforcement member 18 to subsequently shorten. In addition, the clamping members 20, 22 are urged towards each other until they abut the ends of the barrel 32. The ratchet mechanism 30 is operated further to attempt to shorten the webbing 28 which causes an increase in the pressure of the clamping members 20, 22 on the ends of the barrel. Once the clamping force of the clamping members 20, 22 on the ends of the barrel 32 holds the barrel 32 firmly the operation of the ratchet mechanism can be ceased.
A person can grasp the handle section 16 and move the frame to be at an angle to the ground and the barrel 32. Once at an angle the person can push or pull the frame which thereby causes the barrel 32 to roll along the ground and can then be easily manoeuvred in a controlled manner. The person can move the barrel 32 whilst in an upright stance which thereby reduces any strain placed on their back.
The diameter of a beer barrel 32 is greater that the height of conventional steps. In addition, the diameter of a beer barrel 32 may be greater than twice the height of a step. Therefore, if the barrel 32 needs to be moved up some stairs then the person simply pulls the frame and the barrel to the bottom of the first step. Once at the bottom of the first step the person can pull on the frame 10 to move the barrel 32 up the steps. This is not possible with prior art methods using a trolley with small wheels. In addition, the barrel 32 is always under control and cannot become separated from the frame 10.
If the barrel 32 has not been properly clamped in the frame 10 then the barrel 32 may work loose. Beer barrels have annular flanges 34 located at each end of the barrel. The annular flanges 34 project outwardly from the periphery of the barrel from each end. Therefore, if the clamping members 20, 22 work loose from the surface of the ends of the barrel 32 then they will abut an inner part of the annular flanges 34. Accordingly, the beer barrel 32 does not become separated from the frame 10. This enables the barrel 32 to be re-clamped and the barrel 32 will not have been out of control.
Once at the destination, the barrel 32 is removed from the frame 10. In order to release the barrel 32 from the frame 10 the ratchet mechanism 30 is operated to release its grip on the webbing 28. This enables the clamping members 20, 22 to be moved away from each other until the clamping members 20, 22 are spaced apart by a distance greater than the length of the barrel 32. The frame 10 can then be removed from the barrel 32 and the barrel can be manually handled to an upright position if required.
The clamping members are shown in more detail in FIGS. 5, 6 and 7. Each clamping member has a base plate 40. The base plate 40 is circular shape although a different shape can be used. Each clamping member has a shaft (not shown) affixed centrally on one side of the base plate. Each shaft projects from the base plate 40 and through a roller bearing located on the side members. This enables the base plate 40 and hence the clamping members 20, 22 to rotate relative to the side member 12, 14.
On the other side of the base plate 40 there are projections 42 secured thereto. There may be four or five such projections 42 which are radially positioned on the base plate 40. The projections 42 are lengths of hardened steel and may be welded to the base plate 40. Alternatively, the projections 42 may project through the base plate 40 and be secured by a bolt. However, the welded attachment is preferable since the other side of the base plate will not have any projecting portions and this may reduce the overall width of the frame. It is preferable to keep the overall width of the frame as short as possible in order for the frame to be able to manoeuvre beer barrels through narrow gaps.
The projections have a point at their outermost end. The point may provide a small dimple in the surface of the ends of the barrel 32 when clamped. The small dimple will give an improved grip of the barrel by the frame. However, the projections may be rounded or flat at the end. The shape of the ends of the projections may depend upon the container and/or the material of the container.
Each clamping member has a reinforcement plate 44 that is an annular plate. The annular plate 44 strengthens the arrangement of the projections 42. The annular plate 44 has five apertures 45 located radially to enable the projections 42 to pass therethrough. The annular plate 44 has a central aperture. This central aperture and the radial arrangement of the projection 42 enables a spear of a beer barrel to be located therein.
The projections on one of the clamping members may be longer that the projections on the other clamping member. This provides a greater distance from the base plate to the surface of the barrel 32 and, enables the clamping member to easily accommodate the spear of a beer barrel.
In order to improve the grip on the beer barrel 32 a layer of a material may be located between the projections and the surface of the beer barrel 32. This may be a layer of a plastics material and may be a rubber material. The shapes of the ends of the projections may be rounded or flat to improve the grip on the container.
A clamp mechanism 50 may be used as an alternative to the ratchet mechanism 30, as shown in FIG. 8. The clamp 50 has an extending member 52 which is secured to the webbing extending from both side members. The extending member is able to move about a pivot 54 which causes a decrease in the overall length of the webbing. The section of webbing 56 attached to the first side member moves towards the section of webbing 58 attached to the second side member. This causes the first and second clamping members to move towards each other to clamp the container. The clamp can be released to increase the length of the webbing for the container to be removed.
A further embodiment of beer barrel moving apparatus 10 is shown in FIG. 9 and FIG. 10. The apparatus 10 comprises side members 12 and 14, a handle section 16 and a reinforcement member 18. The reinforcement member 16 is adjustable in length in order to move the side members 12 and, 14 towards and away from each other in order to clamp and release the beer barrel.
The reinforcement member 16 comprises a shaft 70 having two open ends at the longitudinal ends thereof. A first extending member 74 projects from the first side member 12 and is slidably engaged within the shaft 70. Similarly a second extending member 76 projects from the, second side member 14 and is slidably engaged in the other end of the shaft 70. The second extending member 76 comprises a flange 78 about its periphery. A spring 80 locates between the flange 78 and the periphery of the shaft 70 in order to urge the shaft 70 away from the second side member 16.
A second flange member 82 locates around the periphery of the first extending member 74. The second flange member 82 is mounted on a carriage 83 which is connected to the shaft 70. The second flange member 82 acts as a retaining means to retain the first extending member 74 at a fixed position relative to the shaft 70. In order to extend or retract the first extending member 74 relative to the shaft 70 a release level 85 can be moved along its longitudinal axis and held in position in order for the first extending member 74 to slidably move relative to the shaft 70. The second flange member 82 is not integral with the first extending member 74 and can be slidably moved along the longitudinal length of the first extending member 74. This retaining means comprises a plate 84 having an aperture defined therein. The first extending member 74 is able to slide through this aperture when the plate is substantially perpendicular to the first extending member 74. However, the first extending member 74 is retained in position relative to the plate 84 and hence the shaft 70 when the plate is at an angle. A spring 87 coupled with an abutment member 89 urge the plate 84 in to an angled configuration when the release lever is at rest. However, when the release lever is pulled along its longitudinal axis towards the second side member 16 the plate 84 can be positioned to be substantially perpendicular relative to the first extending member 74 and the first extending member can be extended from or retracted into the shaft 70. This arrangement enables barrels of different lengths to be secured with the beer barrel moving apparatus 10.
In order to clamp a beer barrel in the beer barrel moving apparatus 10 firstly the second flange member 82 is moved along the first extending member 74 in order for the clamping members 90, 92 to lightly grip the ends of the beer barrel. A lever handle 86 which is pivotally connected to the second extending member through a pivot 88 is rotated around the pivot from an open to a closed position. FIG. 9 and FIG. 10 show the level handle in a closed position. The lever handle may comprise a grip portion 87 to aid the user. As the lever handle 86 is pivoted a lever mechanism comprising a lever member 90 moves the shaft 70 along the second extending member 76 towards the second side member 14. As the shaft 70 moves towards the second side member the first extending member 74 and also the first side member 12 are also moved towards the second side member 12, 14. Therefore, the first and second side members 12, 14 and, hence the first and second clamping members 90, 92 are moved relative towards each other. In order to release the beer barrel, the lever handle 86 is rotated in the opposite direction in order for the side members 12, 14 to move away from each other as encouraged by the spring 80.
The clamp members 90, 92 mounted on the side members 12, 14 may comprise resilient members. The resilient members may provide a good grip of the ends of the barrel. The clamp members 90, 92 may comprise rubber discs or rubber annulars which are mounted on cones and preferably plastic cones. In addition, the clamp members 90, 92 may be able to pivot relative to the side members in order for the plane of the clamp members to be in a different plane, for example the plane of the clamp members may not be exactly vertical. For example, the clamp members may be mounted to the side members by 3 dimensional bearings.
Finally, the beer barrel moving apparatus 10 may comprise a brake mechanism. Each clamp member 90,92 may have a brake shoe 94,96 associated therewith. Each brake shoe 94,96 is operated independently by a brake lever 98,100 mounted on the handle 16. On pulling the brake levers 98, 100 towards the handle 16 the brake shoes 94, 96 are caused to move towards the outer periphery of the clamp members 90, 92 and, eventually, abut the clamp members 90, 92 to inhibit further rotation. The brake mechanism operates using conventional cables. Alternatively, the beer barrel moving apparatus may comprise a single lever operating two brake shoes or a single lever operating a single brake shoe associates with only one clamp member.
The apparatus 10 may be adapted to move other containers especially fluid filled containers, for example gas cylinders, oil drums, chemical drums or plastics containers. The containers may be arranged to contain a volume of a fluid greater than 5 gallons and may be arranged to contain a volume of substantially 9 or 10 or 11 or 18 or 22 gallons of a fluid.
