Abstract
An extendable baton includes a hollow tubular barrel with nesting telescoping members which may be extended to a fully expanded position. The telescoping members are held in the closed position and the opened expanded position by a detent lock, with the ends of the telescoping members designed to engage each other in a positive, rigid, non-interfering relationship by using multiple, parallel tapered stop surfaces.
Claims19
An extendable baton of the type having an outer tubular handle defining a baton axis, the handle with a capped end, an open end and an inner peripheral wall, and at least one nesting, telescoping member having an outer peripheral wall, said telescoping member carried in said handle within said inner peripheral wall and axially movable relative thereto between a fully retracted, nested position, and a fully extended, expanded position, the baton further including means for selectively maintaining the telescoping member in either the retracted or expanded position, said means comprising:
- a. a positive stop for limiting the axial movement of the telescoping member relative to the handle when in the extending position, said positive stop adapted for engaging a portion of the inner peripheral wall of the handle with a portion of the outer peripheral wall of the telescoping member in a noninterfering relationship for maintaining the axial alignment of the handle and the telescoping member;
- b. a locking device movable between a first, locked position and a second, unlocked position for selectively locking the telescoping element in one of the extended and retracted positions;
- and
- c. an annular channel in the inner peripheral wall of the handle, and adapted for receiving the locking device for locking the telescoping element in a retracted position.
An extendable baton of the type having an outer tubular handle defining a baton axis, the handle with a capped end, an open end and an inner peripheral wall, and at least one nesting, telescoping member having an outer peripheral wall, said telescoping member carried in said handle within said inner peripheral wall and axially movable relative thereto between a fully retracted, nested position, and a fully extended, expanded position, the baton further including means for selectively maintaining the telescoping member in either the retracted or expanded position, said means comprising:
- a. a positive stop for limiting the axial movement of the telescoping member relative to the handle when in the extended position;
- b. a detent mechanism in said telescoping member and adapted for moving between a projected, handle engaging position for locking the telescoping member relative to the handle in a retracted position for permitting relative movement between the handle and the telescoping member;
- c. a biasing element for urging the detent mechanism into the projected position;
- d. a first lock element comprising an annular channel in the inner peripheral wall of the handle, and adapted for receiving the detent mechanism when the baton is in the retracted position;
- and
- e. a second lock element associated with said handle for engaging the detent mechanism when the baton is in the expanded position.
An extendable baton of the type having an outer tubular handle defining a baton axis, the handle with a capped end, an open end and an inner peripheral wall, and at least one nesting, telescoping member having an outer peripheral wall, said telescoping tubular member carried in said handle within said inner peripheral wall and axially movable relative thereto between a fully retracted, nested position, and a fully extended, expanded position, the baton further including means for selectively maintaining the telescoping member in either the retracted or expanded position, said means comprising:
- a. a positive stop for limiting the axial movement of the telescoping member relative to the handle when in the extended position;
- said positive stop adapted for engaging a portion of the inner peripheral wall of the handle with a portion of the outer peripheral wall of the telescoping member in a noninterfering relationship for maintaining the axial alignment of the handle and the telescoping member;
- b. a detent mechanism carried by the telescoping member and adapted to project beyond the outer peripheral wall thereof, said detent mechanism movable between an extended, projecting position for selectively engaging said handle and locking the telescoping member relative thereto, in a retracted position for unlocking the telescoping member;
- c. biasing means in communication with said detent means for normally urging the detent means into the extended position;
- d. a first stop surface having a first tapered interperipheral wall portion intersecting the baton axis at a first acute angle and a second tapered interperipheral wall portion intersecting the baton axis at a second acute angle;
- e. a complementary second stop surface on the outer peripheral wall of said telescoping member, said complementary stop surface including first and second tapered wall portions on said outer peripheral wall complementary with and intersecting the baton axis at the same angles as the first stop surface, whereby movement of the telescoping element from the retracted position to the extended position places the complementary first and second stop surfaces in positive, noninterfering engagement with one another;
- and
- f. an annular channel in said interperipheral wall of the handle for engaging the detent means when the telescoping element is in the retracted position for selectively locking the telescoping element in nested, retracted relationship with the handle.
