Abstract
An apparatus provides a means by which a heavy cylindrical object, such as a gas cylinder, may be manually moved by a single person from a vertical standing position in a first location to a second location and, if desired, raised and placed on a storage shelf or platform. The apparatus has clamping mechanism which clamps around the girth of the cylindrical object. Once the cylindrical object is secured within the clamping mechanism, a manual force applied to one end of the cylindrical causes the clamping mechanism and the cylindrical object to pivot, raising the bottom of the cylindrical object from the surface upon which it stands. The apparatus, having ground engaging wheels, may then be pushed to the second location.
Description
APPARATUS FOR HANDLING CYLINDRICAL OBJECTS
AND METHOD OF UTILIZING THE SAME
BACKGROUND OF THE INVENTION
[0001] 1. BACKGROUND OF THE INVENTION
[00021 The present invention provides an apparatus and method for handling cylindrical objects. Such objects may be very heavy, bulky, and awkward to handle with the known manually-operated apparatus. Such cylindrical objects include cylindrical tanks which hold gas and liquids. Such cylindrical objects may further include other cylindrical objects such as artillery rounds, pipe segments, and similar objects which are cylindrical in shape, generally heavy and awkward to handle.
[0003] By way of example, tanks utilized for storing and transporting compressed gas are routinely transported by welders to job locations.
Regulations of the Occupational Safety and Health Administration require that compressed gas cylinders shall be secured in an upright (i.e., vertical) position. However, if supported and held together by a structurally adequate means, gas cylinders may be transported horizontally.
[0004] Maneuvering cylindrical objects presents difficulties, particularly when it is desired to move an object back and forth between a standing position on a floor or other horizontal surface and a horizontal position on a raised shelf or rack.
Many times, cylindrical tanks are moved by an individual by tilting the tank such that a small edge of the bottom of the tank engages the ground surface, and then "rolling" the tank along that edge, with the tank precariously leaning off vertical. When this method is employed, it Is not uncommon for the tank to tilt too far and fall to the ground, presenting a hazard to personnel and to equipment. Raising a cylindrical object, such as a compressed gas tank, to place it on a shelf, rack or vehicle presents additional risks of back injury or the cylindrical object falling and causing injury to personnel and/or =
property.
(0005] Devices exist, such as wheeled hand carts having straps for maintaining the cylindrical object in attachment to the hand cart, which facilitate movement of the cylindrical object along the ground or upon a floor surface. Some devices further provide relatively elaborate or complicated mechanisms for lifting the cylindrical object.
However, embodiments of the presently disclosed invention provide a secured attachment to the hand cart for movement along the ground or upon a floor surface, and also provide a relatively simply manually operated mechanism which provides a mechanical advantage for vertical movement of a cylindrical object back and forth between a vertical position on a horizontal surface, such as a floor, and a horizontal position on a shelf or rack.
SUMMARY OF THE INVENTION
[0006] An embodiment of the present invention is a handling apparatus for handling cylindrical objects, where the handling apparatus comprises a base having a front and a back, a first side member and a second side member in parallel disposition to the first side member, and a cross member spanning between the first side member and the second side member, the front comprising ground engaging front wheels and the back comprising ground engaging back wheels. The apparatus further comprises a tube extending upwardly from the cross member, the tube having a first face.
The apparatus further compries a handle member extending upwardly from the tube the handle member comprising a first rail and a second rail, with an opening defined between the first rail and the second rail. The apparatus further comprises a slide bar having a portion thereof slidingly inserted into the tube, the slide bar further comprising an upward end extending outside of the tube, the slide bar having a second face. The apparatus further comprises an engagement bracket pivotally attached to the upward end of the slide bar, the engagement bracket comprising an openable circular band with a manually operated closure wherein the openable circular band has an open position, in which the cylindrical object may be placed within the circular band, and the circular band has a closed position, in which the manually operated closure is actuated and the circular band circumferentially grasps the cylindrical object, wherein the engagement bracket is pivotal from a horizontal position to a non-horizontal position

9 100461 Engagement bracket 20 is pivotally attached to the upward end of slide bar 18. Engagement bracket 20 comprises an openable circular band 76 which has a manually operated closure mechanism 78. Openable circular band 76 defines an opening within plane surface Pi as shown in Figure 1, where plane surface Pi is generally parallel to a horizontal ground surface 100. When the openable circular band 76 is pivoted to this position, it may be positioned about a cylinder 24. Once a cylinder 24 is received within the openable circular band and the closure mechanism 78 closed to lock the cylinder into the circular band 76, the openable circular band may be pivoted to a second position where the plane surface Pi is perpendicular to the horizontal ground surface as shown in Figure 4.
[0047] Manually operated closure mechanism 78 may be any of a number of known latch devices which pulls tension into the band as the latch is actuated. For example manually operated closure mechanism 78 may comprise a latch member 80 having a latch attached to one end of the circular band 76 and a keeper member attached to the other end. Openable circular band 76 may also have a hinged joint 84 to facilitate the operation of the band. In one embodiment, openable circular band 76 may comprise a first arc member 86 and a second arc member 88 which are joined at hinged joint 84, where the first arc member and the second arc member generally define a circle.
[0048] Figures 2 and 4-6 generally depict a method using the apparatus 10 for moving a cylindrical object, such as a gas cylinder 24, from a first position to a second position. Such second position may include placement of the cylindrical object onto a horizontal storage shelf 90 such as may be in a vehicle 92 or otherwise located. The term "horizontal storage shelf" as used herein is defined as any surface upon which a cylindrical object may be positioned in a generally horizontal orientation for storage, transport, repair, or use. The starting position of the cylindrical object, such as gas cylinder 24, is vertical with the bottom 28 disposed on a horizontal surface, such as a ' floor 30 as generally shown in Figure 2. The apparatus 10 is pushed up to the cylindrical object, such that the cylindrical object is received between the members 38 as shown in Figure 2. The openable circular band 76 of the apparatus 10 is positioned = about the cylindrical object and the manually actuated closure mechanism 78 is = 10 =
actuated by engaging keeper member 82 with latch 80 and closing the handle.
When the manually actuated closure mechanism is actuated, tension is applied to open circular band 76 and it circumferentially grasps the cylindrical object and is locked about it.
[0049] Once the cylindrical object is circumferentially grasped by the circular band 76, the user pushes down on the top 26 of the cylindrical object which, by utilization of the leverage provided by the length of the cylindrical object above the pivot point, causes the engagement bracket 20 to pivot thereby raising the bottom 28 of the cylindrical object from the floor 30. Once the bottom 28 has been raised from the floor 30, the cylindrical object may be moved by pushing the apparatus. It is to be appreciated that the present invention does not require any lifting of the cylindrical object to load it onto the apparatus 10, and once the cylindrical object is moved to the desired location, the user may allow the cylindrical object to resume a vertical position with the bottom 28 of the cylindrical object firmly positioned on the floor, or to raise the cylindrical object to an approximate horizontal orientation and place bottom 28 on support member 94 as shown in Figure 4.
[0050] Once the cylindrical object 24 is in an approximate horizontal position with the bottom 28 supported by support member 94 as shown in Figure 4, the user may lift up on the top 26 of the cylindrical object with the locking mechanism disengaged, causing the slide bar 18 to be raised within the vertical tube 14 until the cylindrical object is a small distance above a horizontal storage shelf 90, at which point the locking mechanism is reengaged to secure the slide bar 18 within the vertical tube 14. At this point, the apparatus 10 may be pushed until the cylindrical object 24 is sufficiently supported by the horizontal storage shelf 90. The user may then release the manually actuated closure mechanism 78 and push the cylindrical object 24 as required to place the cylindrical object entirely upon the horizontal storage shelf 90.
[0051] A cylindrical object may be removed from a horizontal storage shelf 90 and placed in a vertical position on a floor 30 by reversing the steps described above.

[0057] Broadly, this writing discloses at the least the following:
An apparatus provides a means by which a heavy cylindrical object, such as a gas cylinder, may be manually moved by a single person from a vertical standing position in a first location to a second location and, if desired, raised and placed on a storage shelf or platform. The =
apparatus has clamping mechanism which clamps around the girth of the cylindrical object. Once the cylindrical object is secured within the clamping mechanism, a manual force applied to one end of the cylindrical causes the clamping mech9itism and the cylindrical object to pivot, raising the bottom of the cylindrical object from the surface upon which it stands. The apparatus, having ground engaging wheels, may then be pushed to the second location.
[0058] Having thus described the preferred embodiment of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

In one embodiment, openable circular band 76 may comprise a first arc member 86 and a second arc member 88 which are joined at hinged joint 84, where the first arc member and the second arc member generally define a circle.
[0048] Figures 2 and 4-6 generally depict a method using the apparatus 10 for moving a cylindrical object, such as a gas cylinder 24, from a first position to a second position. Such second position may include placement of the cylindrical object onto a horizontal storage shelf 90 such as may be in a vehicle 92 or otherwise located. The term "horizontal storage shelf" as used herein is defined as any surface upon which a cylindrical object may be positioned in a generally horizontal orientation for storage, transport, repair, or use. The starting position of the cylindrical object, such as gas cylinder 24, is vertical with the bottom 28 disposed on a horizontal surface, such as a ' floor 30 as generally shown in Figure 2. The apparatus 10 is pushed up to the cylindrical object, such that the cylindrical object is received between the members 38 as shown in Figure 2. The openable circular band 76 of the apparatus 10 is positioned = about the cylindrical object and the manually actuated closure mechanism 78 is = 10 =
actuated by engaging keeper member 82 with latch 80 and closing the handle.
When the manually actuated closure mechanism is actuated, tension is applied to open circular band 76 and it circumferentially grasps the cylindrical object and is locked about it.
[0049] Once the cylindrical object is circumferentially grasped by the circular band 76, the user pushes down on the top 26 of the cylindrical object which, by utilization of the leverage provided by the length of the cylindrical object above the pivot point, causes the engagement bracket 20 to pivot thereby raising the bottom 28 of the cylindrical object from the floor 30. Once the bottom 28 has been raised from the floor 30, the cylindrical object may be moved by pushing the apparatus. It is to be appreciated that the present invention does not require any lifting of the cylindrical object to load it onto the apparatus 10, and once the cylindrical object is moved to the desired location, the user may allow the cylindrical object to resume a vertical position with the bottom 28 of the cylindrical object firmly positioned on the floor, or to raise the cylindrical object to an approximate horizontal orientation and place bottom 28 on support member 94 as shown in Figure 4.
[0050] Once the cylindrical object 24 is in an approximate horizontal position with the bottom 28 supported by support member 94 as shown in Figure 4, the user may lift up on the top 26 of the cylindrical object with the locking mechanism disengaged, causing the slide bar 18 to be raised within the vertical tube 14 until the cylindrical object is a small distance above a horizontal storage shelf 90, at which point the locking mechanism is reengaged to secure the slide bar 18 within the vertical tube 14. At this point, the apparatus 10 may be pushed until the cylindrical object 24 is sufficiently supported by the horizontal storage shelf 90. The user may then release the manually actuated closure mechanism 78 and push the cylindrical object 24 as required to place the cylindrical object entirely upon the horizontal storage shelf 90.
