Base structure for a walking stick

Abstract

A base structure for a walking stick comprises a body including a connecting support and a plurality of extending legs, the connecting support including a retaining chamber formed around an inner wall thereof to receive a post, and the extending legs extending radially from a bottom end of the connecting support, each of the extending legs including an arcuate arm and a block, and one end of the arcuate arm connected on the bottom end of the connecting support so as to obtain flexibility, the block being located on another end of the arcuate arm and including a plane to abut against the ground; and a washer secured in a bottom surface of the retaining chamber to bias against a bottom end of the post.

1 . A base structure for a walking stick comprising:
 a body including a connecting support and a plurality of extending legs, the connecting support including a retaining chamber formed around an inner wall thereof to receive a post, and the extending legs extending radially from a bottom end of the connecting support, each of the extending legs including an arcuate arm and a block, and one end of the arcuate arm connected on the bottom end of the connecting support so as to obtain flexibility, the block being located on another end of the arcuate arm and including a contacting plane to abut against the ground; and   a washer secured in a bottom surface of the retaining chamber to bias against a bottom end of the post;   wherein the body further includes a flange and a number of reinforcement ribs, the flange is fixed on a connecting portion of bottom ends of the extending legs, and the reinforcement ribs extend outward from an outer wall of the flange to inner side surfaces of the arcuate arms;   wherein the contacting plane includes a number of anti-slip members attached thereon.
