Abstract

Abstract A segmented handle is characterized by an upper gripping member having an opening which partially extends therethrough. At least one lower gripping member is positioned adjacent the upper gripping member and has an opening extending therethrough to permit communication with the opening in the upper gripping member. An apparatus for releasably securing the gripping members in a fixed, coaxial relationship is positioned on adjacent portions of said members. Alternatively, the above apparatus may be disposed in the opening of the upper gripping member.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 244 words
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 2
Dependent Claim 244 words
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
Dependent Claim 16 words
The segmented handle recited in claim 1 wherein the chuck is characterized by a polygonal configuration.
Claim 4
Dependent Claim 269 words
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
Dependent Claim 269 words
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
Dependent Claim 59 words
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
Dependent Claim 37 words
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.
