Abstract
The present invention entails a cane having a finger assembly in the lower portion thereof and extendable from the cane for gripping objects. In particular, the finger assembly is biased toward an extended position. A locking mechanism enables the finger assembly to be locked in an infinite number of positions between a fully extended position and a fully retracted position such that objects of various sizes can be retrieved and held.
Claims12
A cane with extensible fingers for retrieving and picking up objects comprising
- (a) a cane having a hollow body and an opening at its lower end;
- (b) a finger assembly mounted within the lower portion of the cane and moveable between a retracted closed position and an extended open position, the finger assembly including an elongated actuating rod extending within the cane;
- (c) biasing means for biasing the finger assembly toward the extended open position;
- (d) locking means for engaging the finger assembly and locking the same in any position between the extended open position and the retracted closed position;
- the locking means including a spring loaded cam surface for engaging the elongated actuating rod and stationing the same in a locked position so as to lock the finger assembly in a selected position wherein when the locking means is released the finger assembly is outwardly extended by the biasing means and wherein the finger assembly is closed by urging the fingers into the open end of the cane and against the biasing means, and wherein the fingers can be locked in any position while being retracted by engaging the elongated rod with the locking means.
A cane with extensible fingers comprising:
- a cane having an open internal chamber;
- a finger assemble movably mounted within the cane's chamber and movable from a closed retracted position to an open extended position;
- means for biasing the finger assembly toward the open extended position;
- and latching means for locking the finger assembly in an infinite number of positions as the finger assembly is moved from the open extended position to the closed retracted position which is achieved by pushing the finger assembly inwardly into the cane's chamber against the force of the biasing means.
A cane having extensible fingers for picking up and retrieving objects, comprising:
- a. a cane with an internal chamber formed therein;
- b. a finger assembly movably mounted within the chamber and including a pair of fingers movable from a retracted closed position within the chamber to an open extended position where the fingers project from the cane;
- c. the finger assembly further including an actuating rod secured to the fingers and extending upwardly therefrom through the cane chamber;
- d. a spring disposed within the cane's chamber and engaged with the actuating rod for biasing the actuating rod and finger assembly toward the open extended position;
- e. a cane tip secured to the bottom of the cane and having a pair of openings formed therein through which the fingers extend, the openings being particularly directed to spread and open the fingers as they move therethrough in the process of moving from their closed retracted position to the open extended position;
- and
- f. a latching assembly for latching the finger assembly in an infinite number of positions between the open extended position and the retracted closed position, the latching assembly including a lever movably mounted adjacent the exterior of the cane and operatively connected to a camming surface at least partially disposed within the cane's chamber and movable from an engaged position where the same engages and binds against the actuating rod and a disengaged position where the camming surface is spaced from the actuating rod such that the actuating rod can freely move there past, and biasing means for engaging the camming surface and biasing the same toward and into the engaged position, whereby by actuating the lever the camming surface can be released from the actuating rod and the fingers extended wherein the fingers can be latched in any number of positions between the fully opened and closed positions by simply disengaging the camming surface from the actuating rod and pushing the fingers toward the retracted position and releasing the camming surface at any desired position reached so as to lock the fingers in a particular position.
