Abstract
ABSTRACT
There are provided new and useful attachments for carrying steel cylinders for gas comprising a handgrip section terminating in an abutment section adapted to abut against a near side of the cylinder outlet tubing, and a generally U-shaped member extending outwardly from the handgrip section from a level below the abutment section and adapted to loop around a far side of the outlet tubing at a point between the abutment section and the top of the cylinder, whereby when the handgrip section is lifted and rotated relative to the cylinder so that the abutment section abuts against the tubing, the U-shaped section is drawn against the opposite side of the tubing to form an effective grip.

Description
This application relates to attachments for carrying steel cylinders for gas.
BACKGROUND OF THE INVENTION
Various types of steel cylinders for gas are utilized, particularly in the construction and maintenance fields, in situations where the cylinder must be carried from location to location by the tradesman who requires the gas at his place of work.
The gas is generally to be burned in a torch, such as an oxy-acetylene torch. In general, larger such cylinders are provided with wheeled carriers to enable their movement From place to place.
Smaller cylinders, however, have generally not been provided with any carrying means.
This lack of a suitable means for moving intermecliate sized cylinders from place to place is both inconvenient and unsafe. Such cylinders when filled with gas may weigh in the order of 25 pounds, so that it is most unsatisfactory to have no means of aiding in moving the cylinders from place to place.
The present invention was developed against this background. The invention includes a carrying or handle means which is readily attachable and detachable from the cylinder and which provides a very convenient means for gripping the cylinder for transport purposes.
PRIOR ART
The applicant is unaware of any similar prior art devices.
It has been the case that such cylinders are genera'lly simply gripped by the valve structure extending from the top and carried in that manner. No handles or hand carrying devices are known to the applicant.
SUMMARY OF T~E INVENTION
The invention provides a handle-like carrying means which is adapted to readily co-operate with the valve structure protruding from the top of the cylinder.
Thus -there is provided for use with a gas cylinder, a carrying handle adapted t'or removable co-operation with the outlet tubiny from the cylinder and comprising a handgrip section terminating in an abutment section adapted to abut against a near side of the outlet tubing; and a generally U-shaped member extending outward'ly ~rom the handgrip section from a leve'l below the abutment section and adapted to loop around a far side of the out'let tubing at a point between the abutment section and the top of the cylinder;
whereby when the handgrip section is lifted and ro-tated relative to the cylinder so that the abutment section abuts agains~ the tubing, the U-shaped section is drawn against the opposite side of the tubiny to form an effective grip.
BRIEF DESCRIPTION OF THE DRAWINGS
In drawings which illustrate embodiments of the invention, ~,~j, &
s FIGURE 1 is a perspective view of one embodiment of the handle-like carrying device of the presen-t invention; and FIGURE 2 is a side elevation showing the handle-like device fitted over the cylinder outlet tubing and lifted into the operating position.
While the invention will be described in conjunction with a preferred embodiment, it will be unders-tood that it is not intended to limit the invention to such embodiment. On the contrary, it is intended to cover all alternatives, modifications and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTION OF TIIE PREFERRED EMBODIMENTS
_ In the following description, similar features in the drawings have been given similar reference numerals.
With reference to FIGURES 1 and 2, the device of the present invention comprises a handle-like structure lO which includes a hand grip portion 12, a forwardly and upwardly extending abutting portion 14 and a looped or U-shaped section 16. The front face of the abuttment section 14 is preFerably profiled as at 18 to abut snugly against the section 20 of the valve structure which protrudes from the top of the cylinder 22.
The U-shaped section 16 is preferably attached to the device as at 24 in a manner that will permit rotation of the U-shaped section 16. The U-shaped section 16 is preferably of such a diameter toward its outer end 26 that it will when seated on the valve structure 20 fit over the nut 28 which affixes the section 20 to the cylinder outlet 30.
In use, as the hand-grip section 12 is raised relative to the cylinder, the U-shaped section 16 is drawn toward the section 12 and brings up against the side of the nut 28 or the valve or tubing section 20. The front face 18 of the device correspondingly brings up against the opposite side of the valve section 20. The cylinder can thus be very conveniently liFted and carried safely and conveniently from work site to work site.
In the preferred embodiment the device 10 is not fixed to the cylinder or the valve structure in any way. Thus, when a cylinder is returned to a gas supplier for refill, the outlet piping will be removed from the valve structure at the nut 32. The device of the invention can then simply be removed from the valve structure by slipping it up over the upper parts of the structure following lS disconnection at the nut 32. The device can then be positioned on a filled cylinder and the outlet tubing attached at nut 32.
Typically the outlet tubing includes a 90 or T-junction as at 33 and the U-shaped section is located in use between said 90 junction and the top of the cylinders and generally in proximity to the top.
In the preferred embodiment the part of the loop section 16 which lies adjacent the valve structure 20 is at 90 to the axis of structure 20. The U-shaped section 16 may thus be curved longitudin-ally to meet the main body section of the device of the invention at the desired point; or, conversely, the main body section of the device may be designed to preclude the necessity for any curvature in U-shaped section 16. As shown in FIGURE 2, U-shaped section 16 is curved somewhat as shown at 34 so that the outer reach 35 of the U-shaped section lies at about 90 to the outlet tubing 20.
The important aspect of this rela-tionship between the curved section and the face 18 of the section 14 of the device is that the relative positions of the two parts be such as to provide a convenient gripping angle for the hand-grip section 12 of the device 10 when the face 18 and the outer end 26 of the loop section 16 are snugged up against the valve section 20. It is therefore evident that many configurations of the device will fulfil this basic structural requirement.
Thus it is apparent that there has been provided in accordance with the invention an attachlnent for carryin~ steel cylinders for gas that fully satisfies the objects, aims and advantages set forth above. While the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description.
Accordingly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit and broad scope of the appended claims.
