Abstract
Abstract A pickup device for use at the lower end of a walking cane or crutch. The lower end of the cane or crutch is formed as a hollow tubular member that slidably receives a complementary telescoping post. The lower end of the post serves as a frictional tip for the cane or crutch. The post has a gripper in the form of one or more fingers extending longitudinally alongside it which move longitudinally with the post and are received within the tubular end of the cane or crutch when the post is recessed. The gripper is spring biased to permit it to protrude radially outward from the post when the post is extended.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
A crutch or cane, comprising: a hollow upright tube having a center longitudinal axis and an open lower end defined by a transverse edge; means on the tube for manually supporting the user in the manner of a crutch or cane; a coaxial post complementary to the tube interior configuration and slidably mounted therein at the lower end of the tube in a telescoping fashion for longitudinal movement relative to the tube between a first position substantially recessed within the tube and a second position protruding substantially downward from the tube; upright finger means mounted to the post and extending longitudinally alongside said post, the upper end of said finger means being mounted to the post and the lower end thereof being biased outward from the post axis; the lower end of said finger means being movable toward or away from said post in response to longitudinal movement of the post between its first and second positions.
Claim 2
Dependent Claim
157 words
A crutch or cane, comprising: a hollow upright tube having a center longitudinal axis and an open lower end defined by a transverse edge; means on the tube for manually supporting the user in the manner of a crutch or cane; a coaxial post complementary to the tube interior configuration and slidably mounted therein at the lower end of the tube in a telescoping fashion for longitudinal movement relative to the tube between a first position substantially recessed within the tube and a second position protruding substantially downward from the tube; upright finger means mounted to the post and extending longitudinally alongside said post, the upper end of said finger means being mounted to the post and the lower end thereof being biased outward from the post axis; the lower end of said finger means being movable toward or away from said post in response to longitudinal movement of the post between its first and second positions.
Claim 3
Dependent Claim
35 words
The device set out in claim 1 wherein said finger means are recessed within the exterior surfaces of said post in positions flush with the post surfaces when the post is in said first position.
Claim 4
Dependent Claim
30 words
The device set out in claim 1 wherein the post has a frictional rubber tip at its outer end, said finger means longitudinally overlapping a portion of the rubber tip.
Claim 5
Dependent Claim
38 words
The device as set out in claim 1 further comprising motion limiting means connected between the tube and post and defining the limit of movement of the post relative to the tube at said first and second position.
Claim 6
Dependent Claim
64 words
The device set out in claim 1 wherein said finger means is in the form of a length of spring wire bent radially outward relative to the post from the inner end of the wire to its outer end, the inner end of the wire being directed radially inward relative to the post and received through a complementary radial aperture formed in the post.
Claim 7
Dependent Claim
71 words
The device set out in claim 1 wherein said finger means is in the form of a rigid elongated finger movably received within a longitudinal slot formed along the outer surface of the post, the inner end of the finger being pivotally connected to the post about a transverse axis; and spring means between the post and finger yieldably urging the outer end of the finger radially outward from the post.
