Abstract

A shock absorbing shoe with improved assembly and operational performance is provided. The shock absorbing shoe includes: an outsole; an upper sole arranged on the outsole and having a guide portion; a support unit including: a first support body connected to the outsole; and a second support body connected to the upper sole and having a guide part corresponding to the guide portion; an elastic member arranged between the first and second support bodies of the support unit; and a supporting member connected to the first and second support bodies of the support unit, the supporting member being movable upward and downward along the guide portion and the guide part of the second support body.

Claims

1. A shock absorbing shoe with improved assembly and operational performance, comprising:

an outsole (10);

an upper sole (20) having a guide portion (21); and

a pair of support units disposed between the outsole (10) and the upper sole (20), wherein each of the support units includes;

a first support body (30A) bonded to the outsole (10); and

a second support body (30B) bonded to the upper sole (20) and having a first guide part (33) at a position corresponding to the guide portion (21);

a first holding body (35) bonded to the first support body (30A), wherein the first holding body (35) includes a first annular rim (35d) formed along an edge thereof, a first seat depression (35e) formed by the first annular rim (35d), a first fitting protrusion (35c) formed at a center of the first seat depression (35e), and a through-hole (35b) formed at a center of the first fitting protrusion (35c);

a second holding body (37) bonded to the second support body (30B), wherein the second holding body (37) includes a second annular rim (37d) formed along an edge thereof, a second seat depression (37e) formed by the second annular rim (37d), a second fitting protrusion (37c) formed at a center of the second seat depression (37e), a protruding spacer part (36) protruding from the second fitting protrusion (37c) toward the first fitting protrusion (35c), and a second guide part (37a) formed at a center of both the second fitting protrusion (37c) and the protruding spacer part (36);

a single coil spring (41) disposed between the first holding body (35) and the second holding body (37), wherein one end of the single coil spring (41) is fitted into the first seat depression (35e), and the other end of the single coil spring (41) is fitted into the second seat depression (37e); and

a flexible supporting member (50) passing through the first guide part (33), the second guide part (37a), the single coil spring (41) and the through-hole (35b), wherein a protruding spacer part (36) has a length configured in such a way that, when the protruding spacer part (36) contacts the first fitting protrusion (35c) during compression, full compression of the single coil spring (41) is inhibited, and a space remains between the first annular rim (35d) and the second annular rim (37d) to thereby prevent the single coil spring (41) from being damaged due to over-compression and allow bending of the flexible support member (50).

2. The shock absorbing shoe with improved assembly and operational performance as set forth in claim 1, wherein the first support body (30A) includes a first circular depressed seat (31) into which the first holding body (35) is received, and the second support body (30b) includes a second circular depressed seat (31) into which the second holding body (37) is received.

3. The shock absorbing shoe with improved assembly and operational performance as set forth in claim 1, wherein the first holding body (35) includes a seat groove (35a) formed in a lower surface thereof, the supporting member (51) includes an insert hole (55a) formed in a lower end thereof, and a locking pin (60) is inserted into the insert hole (55a).
