Benefits of technology

[0007] In view of this and other disadvantages of the prior art, it is thus one object of the present invention to provide an improved insole board for high-heel shoe which can decrease the producing time and cost of the shoes.

Problems solved by technology

The prior art insole board assembly suffers from a disadvantage that in constructing the assembly there need two step mold processes.
Such two step mold processes would increase the producing time and cost of the shoes.
In addition, the prior art insole board assembly has another disadvantage that for having the heel portion outside the insole board, the shank member is often snapped on the join of the midfoot portion and the heel portion due to the stress formed thereon.

Embodiment Construction

[0019] Referring to the drawings, an insole board for high-heel shoe 10, according to a preferred embodiment of the present invention, includes a board member 12, a plastic molded member 14, and a rigid supporting member 16.

[0020] The board member 12 has a forefoot portion 20, a midfoot portion 22 and a heel portion 24. The midfoot portion 22 and the heel portion 24 are split into an upper layer 26 and a lower layer 28 to form a space 30 to enclose the plastic molded member 14.

[0021] The plastic molded member 14 has a tapered fore-portion 32, an arched mid-portion 34 and a recessed heel-portion 36. The arched mid-portion 34 has a thickness which is gradual decreased respectively from a top point X thereof to each end thereof to connect the tapered fore-portion 32 and the recessed heel-portion 36.

[0022] The contour of the plastic molded member 14 is designed to have a downward curve extended from the top point X to the tapered fore-portion 32 and a second downward curve extended f...

Abstract

An insole board for high-heel shoe includes a board member, a plastic molded member and a rigid supporting member embedded in the plastic molded member. The board member has a forefoot portion, a midfoot portion and a heel portion. The midfoot portion and said heel portion of the board member are split into an upper layer and a lower layer to form a space to enclose the plastic molded member and the rigid supporting member. The plastic molded member is shaped in such a way that a flexline and an arched surface are formed on the surface of the board member. The rigid supporting member and the plastic molded member are formed and enclosed in the space of the board member by one step molding process.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates generally to high-heel shoes and, more particularly, to an improved insole board for high-heel shoe. [0003] 2. Description of the Related Art [0004] In U.S. Pat. No. 4,835,884, a prior art insole board assembly for a high-heel shoe is disclosed to provide the high-heel shoe having a smooth transition from the midfoot area to the forefoot area. The prior art insole board assembly has an insole board with a midportion divided into an upper layer and a lower layer. A shank member has a midfoot portion and a heel portion. The midfoot portion of the shank member is enclosed between the upper layer and the lower layer of the insole board. [0005] The prior art insole board assembly suffers from a disadvantage that in constructing the assembly there need two step mold processes. The firs mold process is to form the shank member. The second mold process is to let the shank member closely conform to the...
