Abstract

(57) [Abstract] [Purpose] To provide a shoe sole structure in which the impact absorbing plate material is prevented from being deformed for a long period of time and the impact absorbing function is not deteriorated. [Structure] On a top surface of a rubber book sole 1 which constitutes a shoe sole, a recess 2 is formed by hanging from a front part 1a of a soil fault to a fingertip part 1b, and a slippery sheet 3 is laid in the recess to sponge the sponge sheet. This is a shoe sole structure in which the elastic shock absorbing plate member 4 is fitted.

[Industrial applications]

 The present invention relates to a shoe sole, particularly a shoe sole structure made of rubber.

[0002]

[Prior art]

 In recent years, not only sports shoes but also casual shoes have been on the market, which can improve the shock absorption function of the sole to give comfortable wear without feeling tired.

In order to enhance the shock absorbing function of the sole, conventionally, a sponge material is used to thicken the sole as a whole, and a hard rubber material is used to make the sole thin (sole). Many shoe sole structures have been proposed, such as one in which a sponge-like shock absorbing plate material is sandwiched between the insole and the shoe bottom looks almost the same as leather shoes.

In the case of a shoe sole configuration in which a sponge-like shock absorbing plate material is sandwiched between a thin outsole and an insole using the above-mentioned hard rubber material, the conventional one has a soil-abrupted front part. A method is adopted in which a shock absorbing plate material is fitted into the concave part formed on the upper surface of the outsole by hanging it from the fingertip part, and the shock absorbing plate material is attached to the bottom surface of the concave part or the insole using an adhesive and incorporated into the shoe. To be

[0005]

[Problems to be solved by the device]

 However, as the sole flexes repeatedly during exercise and walking, the load from the foot is repeatedly applied, and this load creates a moving pressure from the soil fault side to the fingertip side.

Therefore, as described above, in the case of a shoe sole structure in which a sponge-like shock absorbing plate material is sandwiched between the outsole and the insole, the shock absorbing plate material is subjected to a load from the foot. The lower surface part of the is constrained to the bottom side, and the upper surface part is constrained to the insole side. In this state, when a moving pressure is generated from the soil fault part side to the fingertip side, the shock absorbing plate material that is softer than the outsole is pushed from the soil fault part side to the fingertip part side and moves in the surface direction. Twisting expansion and contraction occurs, and by repeating this expansion and contraction, the shock absorbing plate material gradually loses elasticity and the restoring force to return to the original shape weakens, gradually deforming by tending to solidify near the fingertips and improve the comfort. It will cause it to worsen. Further, the deformation of the shock absorbing plate material also reduces the shock absorbing function.

The present invention has been made in view of the above points, and an object thereof is to provide a shoe sole structure that prevents deformation of the shock absorbing plate material for a long period of time and has a small decrease in shock absorbing function. To do.

[0008]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above-mentioned object is to form a recess on the upper surface of a rubber book bottom that constitutes a shoe sole by hanging it from the front of the soil fault to the fingertip. A shoe sole structure is characterized in that a slippery sheet such as a reester sheet is laid on top of which a sponge-like shock absorbing plate material such as a sponge rubber plate is fitted.

[0009]

[Action]

 The lower surface of the shock absorbing plate material does not slide on the slippery sheet and is not constrained to the outsole by the moving pressure generated from the soil fault side to the fingertip side during exercise or walking. Since it returns, the lower and upper parts of the shock absorbing plate do not repeatedly expand and contract such that they are twisted in the direction of the surface, and the elastic force does not decrease over time, and the shock absorbing plate does not lose its elasticity over time. You can maintain the original shape without deformation and maintain comfortable wear.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and is a plan view of the outsole with a part of the shock absorbing plate material removed, and FIG. 2 is a sectional view taken along the line AA of FIG.

In the figure, reference numeral 1 denotes a book sole constituting a shoe sole. The outsole 1 is a rubber bottom made of a hard rubber material, which is obtained by a usual manufacturing method, and the shoe is constructed by assembling the instep and the heel portion by a usual manufacturing method.

Reference numeral 2 denotes a concave portion formed on the upper surface of the book sole 1 by hanging from the soil faulty portion 1 a of the book sole 1 to the fingertip portion 1 b, and the bottom surface of the concave portion 2 has a planar configuration. The depth of the recess 2 is about half the thickness of the outsole 1, and the depth is the same overall. Reference numeral 3 denotes a slip sheet laid in the concave portion 2. The slip sheet 3 is preferably a thin sheet, for example, a polyester sheet (about 0.1 mm) cut. Reference numeral 4 denotes a sponge-like shock absorbing plate material fitted in the recess 2 on the slippery sheet 3, and the shock absorbing plate material 4 is preferably a sponge rubber plate cut. The thickness of the shock absorbing plate member 4 is such that the upper surface of the shock absorbing plate member 4 slightly protrudes above the outsole 1 before it is fitted into the recess 2 and the instep cover is assembled.

Reference numeral 5 in the figure denotes a grounding bottom of the outsole 1.

[0015]

[Effect of device]

 According to the present invention having the above-mentioned configuration, a concave portion is formed on the upper surface of a rubber book bottom constituting a shoe sole by hanging it from the front of the stepless portion to the fingertip portion, and a slippery sheet is laid on the concave portion and sponge Since the shock absorbing plate material is fitted, comfortable cushioning is obtained during exercise and walking, and comfort is improved. Also, during exercise and walking, under the load that is repeatedly applied to the sole, the lower surface of the shock absorbing plate slides on the slippery sheet due to the moving pressure generated from the soil fault side to the fingertip side. Since the shock absorbing plate is not constrained against the outsole, the shock absorbing plate does not repeatedly expand and contract such that the lower surface and the upper surface of the shock absorbing plate are twisted in the in-plane direction, and the shock absorbing plate is released from the moving pressure and instantly becomes the original shape. The impact-absorbing plate does not deform and maintains its original shape over a long period of time without any decrease in elastic force over time, and it has excellent foot fit and does not feel tired. To maintain comfortable wear.
