Abstract

A shoe including: a sock-shaped base member forming at least a portion of an upper; a reinforcement member made of a thermoplastic resin welded to side surfaces of the base member on a medial side and a lateral side of a foot; and a mid sole made of a thermoplastic resin welded to a bottom surface of the base member.

First claim

The invention claimed is:

1. A shoe comprising:
a sock-shaped base member forming at least a side surface of an upper on a medial side of the shoe, a side surface of the upper on a lateral side of the shoe, and a bottom surface of the upper, the sock-shaped base member having a lattice structure;
a reinforcement member made of a thermoplastic resin attached to the side surfaces formed by the sock-shaped base member in a state where the thermoplastic resin is run into the lattice structure so that the reinforcement member is integrated with and anchored in the lattice structure of the sock-shaped base member; and
a midsole made of a non-foamed body of a thermoplastic resin attached to the bottom surface formed by the sock-shaped base member, wherein:
the midsole includes an upper plate, a lower plate, and connecting plates,
the upper plate of the midsole and the bottom surface of the upper are fixed directly to each other by a welding construction,
in fixing by the welding construction, the upper plate is attached to the bottom surface formed by the sock-shaped base member in a state where the thermoplastic forming the upper plate of the midsole is run into the lattice structure so that the upper of the midsole is integrated together with the sock-shaped base member such that it is anchored in the lattice structure, and the upper plate extends in a front-rear direction along the bottom surface,
the lower plate is placed below the upper plate while being spaced apart from the upper plate and facing the upper plate, and the lower plate extends in the front-rear direction while being divided in a medial part on the medial side of the shoe and a lateral part on the lateral side of the shoe,
the connecting plates extend in an up-down direction between the upper plate and the lower plate without being attached to the side surfaces of the upper, and are connected with the upper plate and the lower plate, and three or more connecting plates of the connecting plates are placed on each of the medial and lateral sides of the shoe,
the upper plate and the medial part of the lower plate are integrally connected with each other via the three or more connecting plates placed on the medial side of the shoe,
the upper plate and the lateral part of the lower plate are integrally connected with each other via the three or more connecting plates placed on the lateral side of the shoe,
any two connecting plates, adjacent with each other in the front-rear direction, of the three or more connecting plates placed on the medial side of the shoe are placed so as to face with each other,
any two connecting plates, adjacent with each other in the front-rear direction, of the three or more connecting plates placed on the lateral side of the shoe are placed so as to face with each other,
the upper plate, the medial part of the lower plate, and the three or more connecting plates on the medial side of the shoe each extends in a width direction of the shoe on the medial side, thereby defining a plurality of holes passing through in the width direction on the medial side of the shoe,
the holes on the medial side extend in the width direction only in a part of a total width of the shoe in the width direction,
the upper plate, the lateral part of the lower plate, and the three or more connecting plates on the lateral side of the shoe each extends in the width direction of the shoe on the lateral side, thereby defining a plurality of holes passing through in the width direction on the lateral side of the shoe,
the holes on the lateral side extend in the width direction only in a part of the total width of the shoe in the width direction,
on the medial side of the shoe, each of the connecting plates on the medial side alternates with each of the holes on the medial side,
on the lateral side of the shoe, each of the connecting plates on the lateral side alternates with each of the holes on the lateral side,
the medial part and the lateral part of the lower plate are spaced apart with each other in a part between the medial and lateral sides of the shoe, the connecting plates in the medial and lateral sides of the shoe are spaced apart with each other in the part between the medial and lateral sides of the shoe, thereby the midsole defining a depressed area hollowed upwardly between the medial and lateral sides of the shoe, and
the upper plate defines a plurality of cutouts passing through in the up-down direction, and the lattice structure of the bottom surface formed by the sock-shaped base member is exposed at each of the cutouts and faces to the depressed area.

2. The shoe according to claim 1 , wherein the sock-shaped base member is made of one or two or more of a knit fabric, a knit-like fabric, and a woven fabric that each has the lattice structure, or a primary member of the sock-shaped base member is one or two or more of the knit fabric, the knit-like fabric, and the woven fabric.

3. The shoe according to claim 1 , wherein the medial part and the lateral part of the lower plate are continuous with each other at a front end of the midsole and at a rear end of the midsole, thereby the lower plate being continuous in a loop shape.

4. The shoe according to claim 3 , wherein:
the upper plate includes a medial part placed on the medial side of the shoe, a lateral part placed on the lateral side of the shoe, and at least three bridge plates connecting the medial part and the lateral part of the upper plate, and
each of the cutouts is formed between two bridge plates, adjacent with each other, of the at least three bridge plates.

5. The shoe according to claim 4 , wherein the reinforcement member covers opposing side surfaces of a midfoot, and an eyelet is formed in an upper edge portion of the reinforcement member on each of the side surfaces.

6. The shoe according to claim 4 , further comprising an outsole attached to a lower surface of the midsole and having a greater abrasion resistance than the midsole.

7. The shoe according to claim 1 , wherein:
the reinforcement member that is anchored in the lattice structure comprises eyelets that allow a shoelace to pass through.

8. The shoe according to claim 1 , wherein the reinforcement member is welded to the sock-shaped base member.

9. The shoe according to claim 1 , wherein the reinforcement member and the midsole form a single integral component that is molded in a single molding process.

10. The shoe according to claim 1 , wherein the reinforcement member is more rigid than the sock-shaped base member.

11. The shoe according to claim 1 , wherein:
the upper plate includes a medial part placed on the medial side of the shoe, a lateral part placed on the lateral side of the shoe, and at least three bridge plates connecting the medial part and the lateral part of the upper plate,
each of the cutouts is formed between two bridge plates, adjacent with each other, of the at least three bridge plates,
an upper surface of the depressed area is composed of the at least three bridge plates and the lattice structure of the bottom surface exposed at each of the cutouts,
the lower plate defines an opening in which the depressed area opens downwardly, and
the lattice structure and the at least three bridge plates, both composing the upper surface of the depressed area, are exposed via the opening so as to face a ground surface.
