ABSTRACT:
An upstanding panel member is provided having an opening formed therethrough in an upper portion thereof for snugly, but slidingly receiving the rear end portion of a cylindrical grease gun body therethrough. An elongated lever is hingedly supported, intermediate its opposite ends, from one side of the panel member for oscillation about an axis extending transversely of the lever, spaced outwardly of the opening and disposed generally normal to a line extending between the axis and the center of the opening. One end portion of the lever extends toward and projects slightly into the adjacent portion of the opening when that end portion of the lever is disposed at least generally normal to the center line of the opening and the other end of the lever is spaced outward from the panel member and swingable theretoward in order to swing the first mentioned end portion of the lever away from the panel member and to thus retract the free terminal end thereof away from the opening. Spring structure is operatively connected between the lever and the panel member for yieldingly biasing the lever to a position with the first mentioned end thereof swung toward the panel member and the terminal end thereof projecting slightly into the opening, whereby a cylindrical grease gun body projecting through the opening may be engaged by the end portion of the lever projecting into the opening and retained in position relative to the panel member by the lever.
