Abstract
Abstract A shoe including a mid-sole layer, a lower layer, an air compression cavity, an air envelope, a shoe pad, an inner and outer vamp and an ornament. The air envelope is connected to the air compression cavity via an air-transmission tube which extends from the air compression cavity, passes through the mid-sole layer, is layered between the front end and outer inner of the vamp and extends through to the upper side of the vamp. The air compression cavity is set between the mid-sole layer and the shoe pad corresponding to the position of the heel portion of the shoe so that the air compression cavity is compressed and decompressed periodly as the wearer is walking. The ornament is adhered to the air envelope and is vibrated up and down via the air forced in and out by the air compression cavity in walking.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
268 words
A shoe having a vibratable ornament comprising a mid-sole layer (1), a lower layer (2), an air compression cavity (3), an air envelope (4), a shoe pad (5), an outer vamp (6) and an ornament (7) wherein said air compression cavity (3) is connected with said air envelope (4) via an air-transmission tube (31); said air compression cavity (3) being set at a heel portion of said shoe between said shoe pad (5) and said mid-sole layer (1) and said air envelope (4) being set on an appropriate position of said outer vamp (6); said mid-sole layer (1) having two holes (11, 12) therethrough respectively set on a front and a rear end thereof and a recess (13) on a bottom surface thereof communicating said two holes (11, 12) for the engagement of said air-transmission tube (31); said air-transmission tube (31) passing through the recess (13) of said mid-sole layer (1) from said hole (12) to hole (11) near the front of said mid-sole layer (1) encompassing the front end of the inner suface of said outer vamp (6) and finally extending from said outer vamp (6) to connect to said air envelope (4); said air compression cavity (3) being periodically compressed so as to force air therein to be transmitted to said air envelope (4) via said air-transmission tube (31) when a wearer walks on said shoe; said air envelope (4) comprising appropriate number of wings on which said ornament (7) is adhered so that said ornament (7) is vibrated up or down periodly in conjunction with the compression or decompression of said air compression cavity (3).
Claim 2
Dependent Claim
268 words
A shoe having a vibratable ornament comprising a mid-sole layer (1), a lower layer (2), an air compression cavity (3), an air envelope (4), a shoe pad (5), an outer vamp (6) and an ornament (7) wherein said air compression cavity (3) is connected with said air envelope (4) via an air-transmission tube (31); said air compression cavity (3) being set at a heel portion of said shoe between said shoe pad (5) and said mid-sole layer (1) and said air envelope (4) being set on an appropriate position of said outer vamp (6); said mid-sole layer (1) having two holes (11, 12) therethrough respectively set on a front and a rear end thereof and a recess (13) on a bottom surface thereof communicating said two holes (11, 12) for the engagement of said air-transmission tube (31); said air-transmission tube (31) passing through the recess (13) of said mid-sole layer (1) from said hole (12) to hole (11) near the front of said mid-sole layer (1) encompassing the front end of the inner suface of said outer vamp (6) and finally extending from said outer vamp (6) to connect to said air envelope (4); said air compression cavity (3) being periodically compressed so as to force air therein to be transmitted to said air envelope (4) via said air-transmission tube (31) when a wearer walks on said shoe; said air envelope (4) comprising appropriate number of wings on which said ornament (7) is adhered so that said ornament (7) is vibrated up or down periodly in conjunction with the compression or decompression of said air compression cavity (3).
Claim 3
Dependent Claim
