Definitions

  • the present invention relates to a valve guard.
  • the present invention relates to a valve guard for a gas cylinder valve.
  • Cylinder valve assemblies for gas cylinders and the like are well known. Traditionally, cylinder valves are provided with a hand wheel which is operable by rotation to open and close the valve. More recently, cylinder valves which use levers to operate the valve mechanism have become known. Such a cylinder valve assembly is disclosed in US 5,975,121 .
  • valve guards In order to prevent damage to valve assemblies during transit and/or use, it is common to provide a valve guard. Typically valve guards enclose the valve assembly to a certain extent to afford the necessary protection to the valve. However, this can be problematic as the guard can reduce access to the valve operating mechanism and outlet.
  • the present invention provides a valve guard for a gas cylinder comprising a cylinder and valve assembly, the valve guard comprising a base portion and at least one cantilevered arm extending away from the base portion, wherein, in use, the at least one cantilevered arm is arranged to extend between the base portion and a position substantially in line with a centreline of the cylinder.
  • the cantilevered arm provides protection to the valve assembly in the event that the cylinder is dropped or knocked over, whilst maintaining good access to the valve assembly and outlet.
  • visibility of the valve actuation mechanism is substantially maintained allowing the user to ascertain the position of the actuation mechanism from a large number of angles around the cylinder. This is particularly advantageous for lever operated valve assemblies.
  • the cantilevered arm preferably comprises a bulbous portion located at the distal end of the cantilevered arm to help reduce impact damage to any other item that the guard may hit as it drops or falls over.
  • the bulbous portion preferably comprises a churning knob to aid manual manipulation of the gas cylinder.
  • the base portion is of substantially concave form to provide side protection to the valve assembly.
  • a sidewall portion of the base portion preferably comprises an opening allowing access to the valve assembly and reducing weight of the valve guard.
  • the opening preferably defines a handle to aid manual handling of the gas cylinder.
  • a sidewall portion of the base portion comprises a raised portion to protect particularly delicate parts of the valve assembly.
  • the raised portion is preferably arranged to be located proximate an operating mechanism of the valve.
  • the at least one cantilevered arm is generally of tapered form, tapering from the base portion towards its distal end. This provides strength and stiffness at the base of the cantilevered arm which is most likely to fail during an impact.
  • the valve guard preferably comprises an alignment feature arranged to align with a selected alignment feature on the cylinder or valve to aid correct positioning of the guard on the gas cylinder in relation to the valve assembly.
  • the valve guard comprises at least two sections arranged, in use, to connect together in position around a valve assembly. This aids assembly of the guard around the valve assembly.
  • the present invention provides a kit of parts comprising a plurality of sections for forming a valve guard.
  • the present invention provides a gas cylinder assembly comprising a gas cylinder, a vale assembly and a valve guard as described above.
  • Figure 1 shows a schematic isometric view of a cylinder valve and valve guard assembly with the valve operating lever shown in the "off' position;
  • Figure 2 shows a schematic isometric view of the cylinder valve and valve guard assembly of Figure 1 with the lever shown in the "open" position;
  • Figure 3 shows an isometric view of an alternative cylinder valve and valve guard assembly with the valve operating lever shown in the "off' position;
  • Figure 4 shows an isometric view of the valve guard of Figure 3 in isolation
  • FIG. 5 shows an alternative isometric view of the valve guard of Figure 4.
  • a cylinder and valve assembly 1 is shown comprising a gas cylinder 2, a valve assembly 10 and a valve guard 20.
  • the valve assembly 10 is connected to the cylinder 2 by a threaded connection (not shown) as is well known in the art, and the guard 20 is connected to the neck ring of the cylinder by a threaded connection, also well known in the art.
  • the valve assembly 10 comprises an actuation lever 12 and an outlet 14. In the position shown in Figure 1 the lever 12 is in the downward or "off position such that gas is prevented from flowing from the outlet 14.
  • the valve guard 20 comprises a base portion 21 and a cantilevered arm 22 which extends from the base portion 21 to a distal end 23.
  • the distal end 23 of the arm 22 has a bulbous form and the proximal end 24 of the arm has a thicker cross-section that the cross-section of the arm 22 immediately proximate the bulbous end 23.
  • This configuration provides stiffness to the arm 22 in the region most likely to fail during an impact.
  • the bulbous end 23 serves to reduce impact damage on any object struck by the end 23.
  • the guard material may typically comprise, for example, cast metals, plastics or reinforced plastics.
  • the distal end of the cantilevered arm 22 extends to a position substantially above the centreline of the gas cylinder 2. The arm 22 therefore bends forward over the valve assembly 10. This configuration protects the valve assembly 10 from damage in the event that the cylinder valve assembly 1 is dropped of knocked over.
  • the guard 20 is configured so that if the cylinder valve assembly 1 falls forwards or sideways, in the absence of projecting objects, the first point of contact will not be valve assembly 10 but either the base portion 21 or the arm 22 of the guard 20.
  • FIG. 2 shows the lever 12 of the valve assembly in the raised or "open" position.
  • the valve guard allows almost 360° access to the lever 12 and outlet 14.
  • the position of the lever 12 is easily viewed from the large majority of directions around the cylinder valve assembly 1 , thus allowing the end user to readily ascertain if the valve 10 is open or closed from a larger number of locations.
  • Figure 3 shows an alternative cylinder valve assembly 50.
  • the cylinder valve assembly 50 comprises a gas cylinder 52, a valve assembly 60 and a valve guard 70.
  • the valve assembly 60 comprises an actuating lever 62 and an outlet 64.
  • the guard 70 comprises a base portion 71 and a cantilevered arm 72.
  • the base portion 71 is generally of concave form and has two openings 75 and 76 provided therein. Although generally of concave form, as shown in Figure 3, the large majority of the base portion 71 is located below the valve assembly 60 thereby maintaining access to the valve assembly and outlet 64.
  • the base portion 71 comprises a raised side wall 74.
  • the arm 72 extends from the base portion 71 to a distal end 73.
  • a churning knob 80 is located at the distal end 73 of the arm 72.
  • the cantilevered arm 72 is generally of tapered form, tapering from the base portion 71 towards its distal end 73.
  • the guard 70 is fabricated in two pieces 91 and 92.
  • Bolt holes 78 are provided in each half 91 , 92 and, in use, the two halves are held in place by bolts 78.
  • the assembled guard 70 thus comprises a split line 90.
  • the guard material may typically comprise, for example, cast metals, plastics or reinforced plastics.
  • the side wall 74 is located proximate the lever 62 of the valve assembly ( Figure 3). This affords protection to the lever 62 from side impacts while not unduly limiting the visibility of the lever 62. As shown, because the lever 62 projects beyond the side wall 74, the downward or "off position of the lever 62 can still be seen by a user observing the valve assembly 60 from the opposite side of the wall 74.
  • opening 75 in the guard 70 is arranged to be located behind the valve assembly 60 to allow access to a valve inspection point (not shown). Opening 76 in the guard 70 provides a handle for end users when
  • openings 75 and 76 provide weight savings and material savings, the material saving in particular providing cost savings.
  • the side wall 74 may have an opening to provide an additional grasp point and to provide additional weight saving.
  • the cantilevered arm 72 resides substantially behind the valve assembly 60 at its proximal end 81 and extends to a position substantially above the centreline of the cylinder 52 at its distal end 73. The arm 72 therefore bends forward over the valve assembly 60. This configuration protects the valve assembly 60 from damage in the event that the cylinder valve assembly 50 is dropped of knocked over.
  • the guard 70 is configured so that if the cylinder valve assembly 50 falls forwards or sideways, in the absence of projecting objects, the first point of contact will not be the valve assembly 60 but either the base portion 71 or the arm 72 of the guard 70. It is possible that the lever 62 may be damaged or broken off if the cylinder valve assembly 50 falls over. However, the guard 70 will protect the valve from impacts which may damage the valve and lead to loss of the valve from the cylinder 52.
  • the guard 70 aligns with corresponding features of the valve assembly 60.
  • wall 74 needs to be located proximate the lever 62, and opening 75 needs to be located behind the valve assembly 60.
  • the guard 70 may be provided with an alignment feature (not shown).
  • valve assembly 60 when in place on the cylinder 52 during normal use with the cylinder 52 upright.
  • the front 65 of the valve assembly 60 is that closest to the distal end 63 of the lever 62 when the lever 62 is in the downward or "off position.
