Abstract

A hand-trolley for transporting cylinders is able to be loaded (e.g. with a gas cylinder) with rollers 15 in a horizontal plane, and used to carry the cylinder upright with the rollers 15 in a vertical plane. The hand-trolley has a frame 10 of two generally U-shaped pieces of metal. It has a handle 13 and a load support member 14, the latter including the roller 15. When the trolley is to be loaded it may rest on feet 12 and a pair of wheels 11(a). The trolley may be stood upright on wheels 11(b) with the foot 20 of a member 17 resting on the ground. The foot 20 also helps to support the gas cylinder in an upright position. A gas cylinder may be secured on the trolley by a chain fastened to clips 19. <IMAGE>

Description

SPECIFICATION Hand trolleys This invention relates to hand trolleys, particularly to those for carrying compressed gas cylinders.
Many different designs of hand trolleys are known, each adapted to a particular purpose.
However, trolleys used for the handling of gas cylinders (which are typically relatively heavy) present problems in use in not being manoeuvrable or not adequately providing for transfer of such articles for a substantially vertical carried position to a substantially horizontal carried position. Furthermore, problems arise in the transfer of the heavy articles from the trolley to storage or a carrier vehicle.
The object of the present invention (or at least a preferred embodiment thereof) is to provide a hand trolley capable of meeting or overcoming these disadvantages.
There is provided according to the present invention a hand trolley including a mobile frame which can be supported in a stable position either in a substantially horizontal or vertical manner, the frame being adapted to support and carry a load and including conveyor (or other) means for supporting the load so as to enable simple loading and unloading of said load as desired to be carried out.
Conveniently a movable stop member is provided on said frame for engaging said load and assisting in holding the load against movement during use of the trolley. The stop member is biased to move to its operative position and is pivotally mounted to be moved against said bias to free the load for movement.
The frame typically has at least two pairs of wheels, the trolley being able to be moved or propelled on one of the pairs of wheels with the conveyor means in a substantially horizontal plane and being able to be moved or propelled on the other pair with the conveyor means in a substantially vertical plane in the manner for a normal trolley. The pairs of wheels may be positioned such that the trolley moves through an arc of a circle between said horizontal and vertical planes and vice versa.
The hand trolley according to the invention will now be described, by way of example, having reference to the accompanying drawings in which: Figure 1 is a perspective view of the trolley; Figure 2 is a side view of a loaded trolley in horizontal position, and; Figure 3 is a side view of a loaded trolley in vertical position.
Referring to the drawings, a frame 10 comprises two members or pieces of metal bar, rod, tubing or the like that, very generally speaking, are U-shaped. In Figs. 1 and 2 the frame 10 is shown in a generally horizontal position that is, the axis of the U lies generally horizontally. The frame is mounted on pairs of wheels 11 a and 11 b. The frame is shaped so as to define a handle 1 3 from which feet 1 2 project.
The generally U-shaped members cooperate together to define (at the end of complementary limbs of each U) a load support member 14 comprising two spaced-apart parailel arms.
Between the arms of the support member 14 are mounted a series of roller-conveyors 1 5 upon which a load, such as gas cylinders 16, may be carried.
It will be appreciated that the configuration of the load may vary and also the profile of the rollers and the frame may vary to suit the configuration of the load whilst retaining the inventive concept.
The legs of an abutment member 1 7 are pivotally supported to the said support member 14 by pivot members 18. The member 1 7 carries means (or clips) 1 9 for connecting to a chain or cable 24 for releasably securing the load to the trolley. The abutment member 1 7 includes a foot 20 extending between the legs thereof at one of its ends. The foot 20 helps to support the load when the trolley is in an upright position as shown in Fig. 3.
The pairs of wheels 1 a and 1 b are attached to the other limb of the generally Ushaped frame. When the trolley is in its horizontal (or loading) position as shown in Fig. 1 (and 2), it rests on the wheels 11 a and feet 1 2. By lifting the handle 1 3 and pushing or pulling the trolley may be moved forwards or backwards. When the trolley is in its upright position as shown in Fig. 3 it rests on the foot 20 and the wheels 11 b. It may be moved forwards by tilting the handle, from the side opposite the load, away from the load and then pushing forwards.
A soft resilient buffer of rubber-like material 21 covers leg members (or cross-pieces) 1 Oa extending between the limbs of the two generally U-shaped members defining the frame 1 0. The cross-pieces 1 Oa are situated intermediate the handle 1 3 and the wheels 11 a.
In operation, the load, such as gas cylinders, may be loaded onto the rollers 1 5 with the trolley in the horizontal position as shown or with the trolley in the upright position depending whether the cylinders are stored vertically or horizontally. With the cylinder positioned on the rollers 1 5 the abutment member 1 7 is moved to the position shown and locked in position by chain 24. The trolley if in its horizontal position can then be lifted to an upright position onto wheel pairs 11 b and moved similarly to a conventional trolley. Curved members 10b on the frame are positioned to act as a "third pair of wheels" during movement of the trolley between the vertical and horizontal positions.
During unloading if it is desired to unload the cylinders of like in the horizontal position, such as, for example, onto the tray floor of a motor vehicle, the trolley is again moved to its horizontal position and the abutment member 1 2 freed from the bottom of the load. The load can then be easily rolled off Onto the tray. Similarly, the trolley can be loaded in the same way.
A buffer member 21 is mounted to the cross-pieces 1 Oa and is adapted to abut the tail-gate of the vehicle and prevent damage thereto during a loading and unloading operation.
The configuration can be modified to reposition the handle 1 3 and the wheel supporting frame 10 to allow more convenient handling of the trolley in the horizontal position and on stairs.
The means (or clips) 1 9 is secured to the arms of the abutment member 1 7 so that when a chain 24 is secured to the clips 1 9 the abutment member 1 7 and its associated stop member 20 are prevented from moving from beneath the load (e.g. the gas cylinders 16), therefore preventing accidenatal displacement of the load when fastened onto the trolly.
Also a rubber coated foot may be positioned adjacent the end roller 1 5 of the trolley to engage the tray or floor of a carrying vehicle during loading and unloading to a load member so that the roller does not foul the tray or floor and thereby be prevented from rotating.

Claims (9)
