Abstract
An outsole for shoes includes a top part and a bottom part, the top toe portion of the top part and the bottom toe portion are glued to each other and a chamber is defined between the top and bottom heel portions of the top and bottom part. The top heel portion has multiple top protrusions extending from underside thereof and the bottom heel portion has multiple bottom protrusions extending from a top surface thereof. The top and bottom protrusions are located in the chamber. The respective distal ends of the top and bottom protrusions are glued to each other. The deformation of the top and bottom protrusions absorbs shocks from the ground.
Description
- (1) Field of the Invention
- The present invention intends to provide a shock absorbing outsole which has ideal shock absorbing feature and can be made at low cost.
- (2) Description of the Prior Art
- A
conventional shoe 30 with shock absorbing feature is shown inFIG. 4 and generally includes anoutsole 32 with avamp 33 connected on a top of theoutsole 32 so as to form theshoe 30. A soft andtransparent cell 31 is embedded in the heel portion of theoutsole 32 so as to absorb shocks from the ground. Thecell 31 is made of PVC and the outsole is made by way of blow molding. However, there are several shortcomings for theconventional outsole 32. - The connection of the
vamp 33, thecell 31 and theoutsole 32 is made by using lasting machine and the shoe last to set the desired shape of thevamp 33. After thecell 31 is positioned, the material for theoutsole 32 can be poured into the molds to form theoutsole 32. Nevertheless, thecell 31 is too soft to keep its shape under the pressure during the machining and so that thecell 31 is deformed when being combined with theoutsole 32. Thedeformed cell 31 affects the shape of theoutsole 32. - Besides, when the
cell 31 is combined with theoutsole 32, because thecell 31 is too soft, it cannot bounce back immediately after the wearer applies a load to thecell 31 and this causes uncomfortable wearing experience to the wearers. - The present invention relates to an outsole for shoes and comprises a top part and a bottom part, wherein the top part has a top toe portion and a top heel portion. The top heel portion has multiple top protrusions extending from underside thereof. The bottom part has a bottom toe portion and a bottom heel portion, wherein the bottom heel portion has multiple bottom protrusions extending from a top surface thereof. The top and bottom parts are connected to each other and a chamber is defined between the top and bottom heel portions. The top and bottom protrusions are located in the chamber. The top and bottom toe portions are glued to each other and respective distal ends of the top and bottom protrusions are glued to each other.
- The outsole has the following advantages:
- 1. The material required for the outsole is reduced, this is because the top and bottom heel portions of the top part and the bottom part include curved and recessed top surface and underside.
- 2. The top part and bottom part are connected to each other by glue so that assembling processes are simplified and the manufacturing cost is reduced.
- 3. Because the top part and the bottom part can be made in mass production by using way of molding, the outsoles can be easily formed simply by gluing the top parts and the bottom parts. The cost of laboring can be reduced.
- 4. The connection of the top protrusions and bottom protrusions effectively absorb the force and shocks to reduce injury to the ankles of the wearers.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
-
FIG. 1 is a side view to show a shoe having the outsole of the present invention; -
FIG. 2 is an exploded view to show the top part and the bottom part of the outsole of the present invention; -
FIG. 3 is a cross sectional view taken along line 3-3 inFIG. 1 , and -
FIG. 4 shows a shoe with a conventional outsole in which a cell is embedded. - Referring to
FIGS. 1 to 3 , theoutsole 100 of the present invention comprises atop part 10, abottom part 20 which is connected to thetop part 10. Avamp 102 is connected to thetop part 10 to form the shoe. - The
top part 10 includes atop toe portion 11 and atop heel portion 12. Thetop heel portion 12 has multipletop protrusions 13 extending from underside thereof. Thebottom part 20 includes abottom toe portion 21 and abottom heel portion 22. Thebottom heel portion 22 hasmultiple bottom protrusions 23 extending from a top surface thereof. The thickness of the top andbottom heel portions bottom toe portions bottom toe portions bottom heel portions chamber 101 is defined between the top andbottom heel portions bottom protrusions chamber 101. - The
top heel portion 12 has a curved and recessed underside and thebottom heel portion 22 has a curved and recessed top surface, such that thechamber 101 is defined by the two respective curved and recessed underside of thetop heel portion 12 and the curved and recessed top surface of thebottom heel portion 22. Thechamber 101 is defined transversely through theoutsole 100. - A diameter of each of the top and
bottom protrusions bottom protrusions connection surface 131/231. It is noted that theconnection surfaces outsole 100. Therespective connection surfaces bottom protrusions - When the wearer applies a force to the heel portion of the shoe, the force compress the top and
bottom protrusions bottom protrusions bottom protrusions chamber 101 is narrowed. When the force is shifted to the toe portion of the shoe, the top andbottom protrusions outsole 100 of the shoe provides shock absorbing feature. - The shape of the
top part 10 and thebottom part 20 reduces the material required for theoutsole 100 and the shapes of the top andbottom parts vamp 20 can be made precisely. It is easy to glue thevamp 20, thetop part 10 and thebottom part 20 so that the cost for making the shoe can be reduced. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
