(11) A gas cylinder mobility aid, presented hereafter, is operatively associated with a collar of a gas cylinder to achieve safe, efficient transportation of one or more gas cylinders for various delivery and dock workers. The gas cylinder mobility aid reduces strain associated with heavy, repetitive carrying of gas cylinders and greatly diminishes the hazards associated when rotating one or a stack of gas cylinders forward.

(12) FIG. 1 depicts a perspective view 100 of a gas cylinder mobility aid as in one embodiment. The gas cylinder mobility aid is employed for facilitating safe transportation of one or more gas cylinders, such as but not limited to, thirty three pound aluminum cylinders. The gas cylinder mobility aid is attached to an inner surface of the collar of a gas cylinder and comprises a base plate 102 with an upper surface and a lower surface. One or more coupling members 104 are affixed to the lower surface of the base plate 102 wherein the one or more coupling members 104 are positioned to form a frictional fit with the collar of the gas cylinder.

(13) In FIG. 1, the one or more coupling members 104 are shown as rubber bushings, and the base plate 102 is shown as a rectangular plate. The one or more coupling members 104 may be affixed at opposing lengths of the lower surface of the base plate 102. In alternative embodiments, the one or more coupling members 104 may be affixed at a plurality of one or more corners of the base plate 102. Other shapes of base plates 102, such as square or circular, are considered to be within the scope of other embodiments of the invention. Similarly, the one or more coupling members 104 may be affixed at a plurality of sides of the lower surface of the base plate 102. Additionally, the one or more coupling members 104 may be affixed at a plurality of one or more corners of the base plate 102. Furthermore, a plurality of coupling members 104 may be affixed equidistant from one another on the lower surface of the base plate 102. In the embodiment having a circular base plate 102, the one or more coupling members 104 may comprise one continuous coupling member 104 positioned around the circumference of the base plate 102, or a plurality of coupling members 104 positioned around the circumference of the base plate 102.

(14) In FIG. 1, two rubber bushings are affixed to a distal end of the lower surface of the base plate 102 and are each secured in place by a steel lock nut 106. Other fasteners in the art such as, but not limited to, screws 108, washers 110 and spacers may be further employed in the assembly of the gas cylinder mobility aid.

(15) The gas cylinder mobility aid further comprises a vertical member, not presently shown in FIG. 1, affixed at the center of the base plate 102, and a handle, displayed in FIG. 1 as a spherical handle 112, rotatably attached to the vertical member such that the handle is present above the upper surface of the base plate 102 and the handle rotates about the vertical member. During assembly, the vertical member may be passed through a hole in the base plate 102 and extend vertically at a right angle from the upper surface of the base plate 102. In some embodiments, the vertical member comprises a first end and a second end where the handle is attached at the first end of the vertical member and the base plate 102 is attached at the second end of the vertical member.

(16) The base plate 102, one or more coupling members 104, the vertical member and the finger guard 114 may be fixed together such that only the spherical handle 112 is able to rotate. In some embodiments, the finger guard 114 may be built into the base plate 102. In some embodiments, the gas cylinder mobility aid contains an attachment member affixed to the lower surface of the base plate 102 opposite to the handle. In other embodiments, the attachment member is attached to the vertical member at the end opposite to the handle. In other embodiment, the handle is fixed while the base plate 102, the vertical member and the coupling members 104 rotate during transportation. In some embodiments, the attachment member couples to a user's belt.

(17) Within FIG. 1, the vertical member, such as but not limited to a socket cap head screw, is enclosed within the spherical handle 112, finger guard 114, base plate 102, washer 110 and steel lock nut 106 assembly. The assembly presented provides durability while remaining inexpensive to manufacture and maintain. Additionally, the gas cylinder mobility aid may be manufactured to be lightweight, thus providing effortless portability and stowability. The gas cylinder mobility aid may be manufactured in a variety of different sizes to fit various different gas cylinder dimensions.

(18) FIG. 2 depicts a top view 200 of the gas cylinder mobility aid as in one embodiment. An outline for a gas cylinder collar 202 is present to indicate the orientation of the gas cylinder mobility aid while employed, specifically, the orientation of the coupling members 104 in relation to the gas cylinder collar 202 and the position of the spherical handle 112 in relation to the central axis of the gas cylinder collar 202 is illustrated. The gas cylinder mobility aid utilizes the central axis of the gas cylinder for facilitating effortless and safe transportation during rotation of the one or more gas cylinders, while reducing time spent during transportation dramatically. Furthermore, the finger guard 114 in the present embodiment is attached to the vertical member, not presently shown, and utilized to prevent the user's fingers and hands from becoming caught between the base plate 102 and the gas cylinder collar 202 during employment of the gas cylinder mobility aid.

(19) FIG. 3 depicts a bottom view 300 of the gas cylinder mobility aid as in one embodiment. In this embodiment, the outline for a gas cylinder collar 202 further demonstrates the seating of the coupling members 104 onto the inner gas cylinder collar 202. The coupling members 104 engage and are positioned into place along an inner circumference of the gas cylinder collar 202 such that a frictional fit is formed while overcoming any rough or damaged surface of the inner gas cylinder collar 202. In other embodiments, the coupling members 104 engage and are positioned into place along an outer circumference of the gas cylinder collar 202 such that a frictional fit is formed. In another embodiment, the gas cylinder mobility aid is manufactured as a single unit. In some embodiments, one or more of the base plate 102, the one or more coupling members 104, the vertical member and the handle are manufactured by a 3-D printer. In other embodiments, one or more of the base plate 102, the one or more coupling members 104, the vertical member and the handle are manufactured by an injection molding.

(20) FIG. 4 depicts a front view 400 of the gas cylinder mobility aid as in one embodiment.

(21) FIG. 5 depicts a side view 500 of the gas cylinder mobility aid as in one embodiment.

(22) FIG. 6 depicts a single gas cylinder application 600 of the gas cylinder mobility aid as in one embodiment. A method of employing the gas cylinder mobility aid to facilitate safe transportation of a gas cylinder 602 comprises applying the one or more coupling members 104 to the collar 604 of the gas cylinder 602 such that a frictional fit is formed. Next, the user tilts the gas cylinder 602, which may be at angle of approximately three degrees for example. Furthermore, the user applies a rotational force to the gas cylinder 602 while securing the handle and guiding the gas cylinder 602 via the handle.

(23) After positioning the gas cylinder mobility aid to the gas cylinder 602 and tilting the gas cylinder 602, the user exerts an initial force to rotate the gas cylinder 602 but very few, if any, other exertions by the user are required thereafter. The ease of use is due to the combination of the frictional fit of the coupling members 104 against the collar 604 in combination with the rotation of the handle. The gas cylinder mobility aid allows for single-handed employment of the apparatus once the rotation of the gas cylinder has begun and simple guidance of the gas cylinder 602 towards a targeted destination during rotation as oppose to most other methods which require constant two-handed operation. In some embodiments, the method may be further employed to transport two or more gas cylinders 602. In other embodiments, the method may be further employed such that the gas cylinders 602 are stacked on top of each other such as in FIG. 7.

(24) FIG. 7 depicts a multiple gas cylinder application 700 of the gas cylinder mobility aid as in one embodiment. This embodiment shows an example where a gas cylinder 602 may be stacked such that a top gas cylinder 702 rest on top of a bottom gas cylinder 704. The gas cylinder mobility aid may be employed to the top gas cylinder 702 in the stack and applied in the same manner previously stated to facilitate safe transportation.

(25) The considerable weight of a single or stacked gas cylinders 602 may be hazardous in the event of a sudden deviation from the intended path or an unexpected collapse of a stack of gas cylinders 602. Handle shapes may be employed, such as but not limited to, oblate, prolate, spherical handles 112 or other such shapes that prevent the user's fingers or hands from becoming lodged within the handle. These handles may be manufactured from materials, such as but not limited to, hardwood, which is cost quite effective or polycarbonate, which provides durability.

(26) A gas cylinder mobility aid kit for facilitating safe transportation of one or more gas cylinders 602 comprises a base plate 102, a plurality of coupling members 104, a vertical member, a handle and a plurality of fasteners. In some embodiments, the gas cylinder mobility aid kit further comprises a finger guard 114. In some embodiments, the handle is spherically shaped.
