Abstract
A police baton or the like of telescoping tubular sections normally carried in a collapsed telescoped condition and extensible by releasing a safety lock in the handle and exerting pressure upon an eject button to release a catch and permit an internal expansive helical spring to telescopically extend the sections of the baton, operation of the safety lock and of the eject button being accomplished by movement of those elements in readily distinguishable directions of operational motion.
Claims13
A police baton comprising,
- at least a pair of telescoping tubes movable to extend and collapsed positions,
- cooperating separably engageable stop portions adjacent the inner end of one tube and the outer end of the other tube to limit the extended movement of the tubes,
- one of the tubes having a handle end,
- spring means interposed between one of said handle end and its tube and the other tube and biasing said other tube to an extended position,
- a catch device carried by said one of said handle and one of said tubes and releasably engaging said other tube for extension by said spring means,
- and a safety lock associated with said catch device to releasably secure the catch device against release from said other tube.

A police baton comprising,
- at least a pair of telescoping tubes movable to extended and collapsed positions,
- cooperating separably engageable stop portions adjacent the inner end of one tube and the outer end of the other tube to limit the extended movement of the tubes,
- one of the tubes having a handle end,
- spring means interposed between one of said handle end and its tube and the other tube and biasing the other tube to an extended position, a catch device carried by said one of said handle and one of said tubes and releasably engaging said other tube for extension by said spring means,
- and said other tube having an abutment facing generally towards the direction of extension of said other tube,
- a catch element movable into and out of abutment engaging position,
- and an actuator for said catch element to move it out of abutment engaging position.
4 more elements
A police baton comprising,
- a pair of telescoping first and second tube units,
- the first tube being relatively stationary and having a handle end with a handle thereon,
- the second tube lying within the first tube and its extensible longitudinally therein,
- means associated with said tubes for limiting telescoping extension thereof,
- the second tube unit having an inner end adjacent said handle when the baton is collapsed,
- said inner end of the second tube having abutment means facing generally toward the outer end of said tube,
- a catch element carried by said handle normally biased to a position to be engaged by said abutment means and prevent outward extension of the second tube,
- and an actuator carried by said handle and movable relative thereto to shift said catch element away from said abutment means.
