A bag restraining system, and method of its use is diclosed. The bag restraining system, in its preferred embodiment, provides a device that can be easily attached to existing two wheel transport units while providing a vast range of vertical and horizontal adjustment necessary to effectively restrain and accommodate bages of various lengths and/or diamters. The system provides for the quick and easy removal of the protruding elements, on which bags are restrained, from the two wheel transport unit to allow immediate use of the two wheel transport unit in a material transport capacity when desired. The system incorporates automatic gripping, force controlling and distributing compressible material elements which, either alone or in conjunction with forces developed by rotating members, control and distribute the restraining forces exerted on a restrained bag. The system also provides for quick and easy bag release. Said attributes help to prevent the development of high stresses in restrained bags which result from application of large forces at points thereon, and thereby minimize the possibility that bags restrained in the system will be torn. The system is also essentially self contained thereby minimizing the chance that parts thereof will be lost.

A bag restraining system, which bag restraining system comprises a base mounting rail, which base mounting rail, when viewed from the front with the longitudinal dimension oriented horizontally and the width dimension oriented vertically in elevation, presents with right and left side elongated slot
A bag restraining system, which bag restraining system comprises a base mounting rail, which base mounting rail, when viewed from the front with the longitudinal dimension oriented horizontally and the width dimension oriented vertically in elevation, presents with right and left side elongated slots therein, positioned longitudinally to the right and left of the longitudinal center line which is perpendicular to the longitudinal dimension of the base mounting rail at the mid point thereof, and which elongated slots are in line with, or parallel to, the vertical center line which extends the longitudinal to, the vertical center line which extends the longitudinal length of the base mounting rail at the vertical mid point thereof; which base mounting rail further has a multiplicity of right and left side complimentary pairs of detachable connection means, which bag restraining system further comprises right and left side arms, which right and left side arms attach to, in an easily removable manner, and project perpendicularily from the base mounting rail, by way of said detachable connection means, which mesh with complimentary connection means present on the back of each of the right and left side arms within the breadth dimensional area thereof, and to which right and left side arms, on the outer vertical surfaces thereof are attached pivot brackets, to which pivot brackets are attached restraining levers by way of pivot pins such that the restraining levers are free to rotate about their pivot pin connection points in a partial arc limited to what is termed the closed restraining space position which, for the right restraining lever, is in the clockwise direction and where the length of the right restraining lever nearest the outer vertical surface of the right side arm contacts the outer vertical surface of the right side arm and the lower aspect of the outer horizontal extent of the right restraining lever is in contact with or in close proximity to the top of the right pivot bracket to prevent over-rotation of said right restraining lever, and for the left restraining lever, is in the counter-clockwise direction and where the length of the left restraining lever nearest the outer vertical surface of the left side arm contacts the outer vertical surface of the left side arm and the lower aspect of the outer horizontal extent of the left restraining lever is in contact with or in close proximity to the top of the left pivot bracket to prevent over-rotation of said right restraining lever: in which closed restraining space position the top open edge of a bag, or other materials, can be restrained, which restraining levers are each, in length, a significant portion of the length of the side arms to which they are attached so that bag restraining force distribution along said length can be achieved in use, thereby avoiding point application thereof to a bag, or other material, restrained in the bag restraining system.
