Abstract
An extendable pole mechanism may be used with a pair of poles that are longitudinally movable to adjust the overall length of both poles. The mechanism may include a housing that receives the poles and a trigger that is moveable with respect to the housing to adjust the mechanism between a use condition, where the poles are held in a longitudinally relative fixed position, and an adjustment condition, where the poles are longitudinally moveable with respect to each other.
Claims20
An extendable pole mechanism for use with a first associated pole that is longitudinally movable with respect to a second associated pole to adjust the overall length of both poles, the extendable pole mechanism comprising:
- a housing that receives the first and second associated poles;
- a first contact device that:
- (1) is supported to the housing;
- and, (2) is moveable with respect to the housing;
- a second contact device that:
- (1) is supported to the housing;
- and, (2) is moveable with respect to the housing;
- a first lever that is:
- (1) is supported to the housing;
- and, (2) is moveable with respect to the housing;
- a second lever that is:
- (1) is supported to the housing;
- and, (2) is moveable with respect to the housing;
- a trigger that is:
- (1) is supported to the housing;
- and, (2) is moveable with respect to the housing;
- and,
- wherein the extendable pole mechanism is adjustable by moving the trigger with respect to the housing to cause the first and second levers to move with respect to the housing to cause the first and second contact devices to move with respect to the housing between:
- (1) a use condition where the first associated pole is held by contact with the first and second contact devices in a longitudinally fixed position with respect to the second associated pole;
- and, (2) an adjustment condition where:
- (a) the first associated pole is not held by contact with the first and second contact devices in a longitudinally fixed position with respect to the second associated pole;
- and, (b) the first associated pole is longitudinally moveable with respect to the second associated pole.

- (a) the first associated pole is not held by contact with the first and second contact devices in a longitudinally fixed position with respect to the second associated pole;
- and, (b) the first associated pole is longitudinally moveable with respect to the second associated pole;
- a first biasing device that exerts a first biasing force that biases the first contact device toward contact with the first associated pole;
- and,
- a second biasing device that exerts a second biasing force that biases the second contact device toward contact with the first associated pole.
