Variable length tool handle

Claim 2

A segmented handle of variable length which is characterized by: (a) an upper gripping member having a opening which partially extends longitudinally therethrough whereby the opening is dimensioned and configured to accomodate a chuck and cooperate with releasable retention means disposed on the chuck; (b) at least one lower gripping member (i) positioned adjacent to the upper gripping member, and (ii) having an opening extending longitudinally therethrough whereby a shaft may be inserted into the opening in the lower gripping member and communicate with the upper gripping member; (c) a hollow shaft dimensioned and configured (i) for receiving a chuck at either end and cooperating with releasable retention means on the chuck, and (ii) to be received by the opening in the lower gripping member; (d) a means for preventing rotational slippage of the hollow shaft in relation to the lower gripping member; (e) at least one chuck dimensioned and configured to be received both within one end of the hollow shaft and the upper gripping member; and (f) a means disposed on the chuck for releasably retaining the chuck within the shaft and the upper gripping member; thereby providing a secure connection between the combined gripping members and the shaft when the chuck is inserted into both the one end of the shaft surrounded by the lower gripping member and into the opening in the upper gripping member, and also permitting a secure connection between the chuck and the upper gripping member alone.

Claim 3

The segmented handle recited in claim 1 wherein the chuck is characterized by a polygonal configuration.

Claim 4

A segmented handle of variable length which is characterized by: (a) an upper gripping member having an opening which partially extends longitudinally therethrough whereby the opening is dimensioned and configured to accomodate a chuck disposed in the upper end of a hollow shaft; (b) at least one gripping member (i) positioned adjacent to the upper gripping member, and (ii) having an opening extending longitudinally therethrough whereby a shaft may be inserted into the opening in the lower gripping member and communicate with the upper gripping member; (c) a means disposed on the adjacent portions of the gripping members for releasably securing said members in a fixed coaxial relationship; (d) a hollow shaft dimensioned and configured (i) for receiving a chuck at either end and cooperating with a releasable retention means on the chuck, and (ii) to be received by the opening in the lower gripping member; (e) a means for preventing rotational slippage of the hollow shaft in relation to the lower gripping member; (f) at least one chuck dimensioned and configured to be received both within one end of the hollow shaft and the opening of the upper gripping member; (g) a means disposed on the shaft for releasably retaining the shaft in relation to the lower gripping member; and (h) a means disposed on the chuck for releasably retaining the chuck within the shaft and the upper gripping member; thereby providing a secure connection between the shaft and the combined gripping members when said members are disposed in the fixed coaxial relationship, and also permitting a secure connection between the chuck and the upper gripping member alone.

Claim 5

A segmented handle of variable length which is characterized by: (a) an upper gripping member having an opening which partially extends longitudinally therethrough whereby the opening is dimensioned and configured to accomodate a chuck disposed in the upper end of a hollow shaft; (b) at least one gripping member (i) positioned adjacent to the upper gripping member, and (ii) having an opening extending longitudinally therethrough whereby a shaft may be inserted into the opening in the lower gripping member and communicate with the upper gripping member; (c) a means disposed on the adjacent portions of the gripping members for releasably securing said members in a fixed coaxial relationship; (d) a hollow shaft dimensioned and configured (i) for receiving a chuck at either end and cooperating with a releasable retention means on the chuck, and (ii) to be received by the opening in the lower gripping member; (e) a means for preventing rotational slippage of the hollow shaft in relation to the lower gripping member; (f) at least one chuck dimensioned and configured to be received both within one end of the hollow shaft and the opening of the upper gripping member; (g) a means disposed on the shaft for releasably retaining the shaft in relation to the lower gripping member; and (h) a means disposed on the chuck for releasably retaining the chuck within the shaft and the upper gripping member; thereby providing a secure connection between the shaft and the combined gripping members when said members are disposed in the fixed coaxial relationship, and also permitting a secure connection between the chuck and the upper gripping member alone.

Claim 6

The segmented handle recited in claim 3 wherein the means disposed on the adjacent portions of the gripping members is characterized by a plurality of pins disposed on one member and an equal number of spring-biased ball detents disposed in the other member whereby each pin may be releasably secured in an appropriately positioned detent by the spring-biased ball.

Claim 7

The segmented handle recited in claims 3 or 4 wherein the means disposed on the shaft for releasably retaining the shaft is characterized by a spring-biased ball which releasably engages the opening in the lower gripping member.
