A holder for the shank of a tool comprising a cylinder having a series of shoulders and grooves in radial formation with the shoulders and grooves allowing for O-rings to penetrate to the interior and exterior of the cylinder to form a means whereby the shank of a tool can be inserted and the tool held in position. As an alternative embodiment the shoulders and grooves can be helical around the cylinder with rubber latex tubing in the grooves and penetrating to the interior and exterior of the cylinder to thereby hold a tool or implement. Also note that a tool can be inserted at either end of the cylinder; and that an oversize cylinder can be inserted over the cylinder and held by the exterior portion of the O-ring or latex tubing. A special embodiment of this invention is the formation of a grommet employing a tubular portion to form a ring into which is cut grooves forming shoulders and into which is inserted an O-ring to form a grommet.
A holder for the shank of a tool comprising a tubular sleeve having a series of parallel shoulders and circular grooves, wherein from the midpoint of the sleeve a plurality of said shoulders and grooves extend in each direction axially, and wherein said series of parallel shoulders and circular grooves contain O-rings which are spaced along the length of the tubular sleeve and wherein said circular grooves are open to the inside of the tubular sleeve and which the circular grooves and shoulders allow portions of the O-rings to protrude inwardly and outwardly to provide a means to hold the shank of a took when the tool shank is inserted into the tubular sleeve, wherein the tool can be inserted easily at either end of the tubular sleeve and the tool can be easily removed.
A holder for the shank of an implement, comprising a tubular sleeve having shoulders and helical grooves formed therein, and an elastomeric coil wound over the shoulder within the helical groove and partially protruding inwardly and partially outwardly thereof, such that the inwardly-protruding elastomeric coil grips the shank of the implement and retains the shank of the implement within the sleeve, and such that the implement may be slid outwardly of the sleeve by a manual force, and the tubular sleeve being able to receive the implement from either end.
