Abstract

There is provided a guard structure for a gas cylinder assembly, the gas cylinder assembly comprising a gas cylinder body and a valve, the gas cylinder body including a base and a neck to which a proximal end of the valve is connected in use, the guard structure being securable to the gas cylinder assembly and comprising a guard body arranged, in use, to surround the valve, wherein the guard body further comprises a dependent lip extending around substantially the entire perimeter of the guard body, the dependent lip being located and arranged to be graspable by at least one user to enable the gas cylinder assembly to be lifted and/or maneuvered.

First claim

The invention claimed is:

1. A guard structure securable to a gas cylinder assembly having a gas cylinder body and a valve, the gas cylinder body including a base and a neck, the valve being bounded by a proximal end connected, in use, to the neck of the gas cylinder body and a distal end remote from the neck of the gas cylinder body, the distal end of the valve having an upper surface opposite and most distal from the gas cylinder body, the guard structure comprising:
a mounting structure having a base attached, in use, to the upper surface of the distal end of the valve and extending further distal from the valve;
one or more fasteners securing the base of the mounting structure to the upper surface of the distal end of the valve;
a guard body supported, in use, by the mounting structure, and surrounding the mounting structure and the valve; and
a dependent lip extending downwardly from a lower portion of the guard body and positioned radially outward from the neck of the gas cylinder body such that fingers of a user can be hooked under the dependent lip to enable the gas cylinder assembly to be lifted and/or manoeuvred.

2. The guard structure according to claim 1 , wherein the dependent lip extends around substantially the entire perimeter of the guard body.

3. The guard structure according to claim 1 , wherein the dependent lip arranged to surround at least a portion of the neck of the gas cylinder body when the guard structure is located on the gas cylinder assembly.

4. The guard structure according to claim 3 , wherein the dependent lip is arranged, in use, to extend from a position of conformal contact with the neck of the gas cylinder body and/or a portion of the valve.

5. The guard structure according to claim 1 , wherein the dependent lip is integrally formed with the guard body.

6. The guard structure according to claim 1 , wherein the mounting structure is formed from metal and/or has a substantially circular cross section.

7. The guard structure according to claim 1 , wherein the guard body comprises first and second clamshell portions.

8. The guard structure according to claim 7 , wherein portions of the first and second clamshell portions are arranged to engage conformally with the mounting structure attached to the valve.

9. The guard structure according to claim 8 , wherein the guard body further comprises a rotatable cap locatable to secure the first and second clamshell portions to the mounting structure, the rotatable cap being rotatable about a longitudinal axis of the gas cylinder assembly.

10. The guard structure according to claim 1 , wherein the guard body is formed from a plastics material.

11. A valve assembly comprising a valve and the guard structure according to claim 1 .

12. A valve assembly according to claim 11 , wherein the valve assembly comprises a proximal end connectable to a gas cylinder body and a distal end secured to the mounting structure.

13. A gas cylinder assembly comprising a gas cylinder body and a valve assembly according to claim 11 .

14. The guard structure according to claim 1 , wherein the dependent lip extends downwardly and outwardly.
