ABSTRACT OF THE DISCLOSURE A reinforced athletic shoe includes an upper member of woven fabric material, a first reinforcing member joined with the lower peripheral portion of the upper member, and toe and heel reinforcing members joined with the first reinforcing member and upper member. The upper member and the reinforcing members are stitched to a sole which includes upper and lower cloth members made of woven fabric material joined by cement and a 'bottom member formed of wear-resistent synthetic rubber.

The present invention relates to an improvement in joint portions of athletic shoes to be chiefiy used in wrestling, boxing or like sports.

An object of the present invention is to provide athletic shoes having effective joint portions which can fully withstand high compression and tensile forces produced at the joint portions between shoe uppers and shoes during athletic activities and which are therefore free from breakage due to those high compression and tensile forces.

Another important object of the present invention is to provide athletic shoes which are formed with effective reinforcements in the portions most susceptible to breakage so as to avoid the uneconomical use of material.

Still another object of the present invention is to provide athletic shoes which are comfortable to put on and in which the joint portions can be readily formed.

Other objects and advantages of the present invention will become apparent from the following detailed description with reference to the accompanying drawings, in which: v

FIG. l is a front view showing an athletic shoe of the present invention;

FIG. 2 is an enlarged view in section showing the structure of the principal part of a joint portion in the athletic shoe of the present invention;

FIG. 3 is an enlarged View in section showing the principal part of a joint portion in the athletic shoe of the present invention;

FIG. 4 is a View in section showing an upper in the joint portion of FIG. 2 as it is disassembled.

FIG. 5 is a view in section showing an upper in the joint portion of FIG. 3; and

FIG. 6 is a view in section showing the sole as it is disassembled.

Although the athletic shoe of the present invention will be described in detail with respect to an embodiment thereof, the present inventor does not wish to limit the Re. 27,512 Ressued Oct. 24, 1972 ice invention only to such embodiment, but it should be understood that the invention also includes various equivalents, modifications, and alterations Without departing from the spirit of the inventor and the scope of claims as set forth below.

Designated at 1 is an upper forming the upper portion of an athletic shoe and comprising an upper member 2 for covering the instep, a first reinforcing member 3 for reinforcing the lower peripheral portion of the upper member and a second reinforcing member 4 for reinforcing the first reinforcing member at the toe or heel portion. The upper member 2 is formed of a tough woven cotton fabric such as canvas or of a woven fabric made of synthetic fibers such as polyamide resin fibers, polyester resin fibers, or some other resin material equivalent to these resins fibers. rl"he first reinforcing member 3 is formed of a film or leather made of a synthetic resin which are highly joinable with the upper member 2 such as polyamide resin, polyester resin, polyvinyl chloride resin or the like. Further, the second reinforcing member 4 is to be joined with the external surface of the first reinforcing member 3 around the toe portion and/ or heel portion, and is formed of a thick leather, or of a film or leather relatively large in thickness which is made of a synthetic resin such as polyamide resin, polyester or -polyvinyl chloride.

Designated at 5 is a sole for forming the under face of the athletic shoe comprising a cover sheet 6 and a rubber sole 7 to be brought into contact with the ground. The cover sheet 6 is formed of pieces of cloth 8 and 8 of a tough cotton fabric like canvas or of a tough woven fabric made of synthetic fibers such as polyamide resin fibers, polyester resin fibers or the like, with a thick rubber cement layer or natural or synthetic rubber piece 9 interposed between the cloth pieces. The rubber sole 7 to be joined with the cover sheet 6 is made of natural or synthetic rubber including wear-resisting material mixed therewith. Applicable as the rubber cement are latex solution, rubber chloride adhesive obtained by reacting natural rubber with chloride, urethane rubber adhesive, chloroprene rubber adhesive, nitrile rubber adhesive, etc.

Enumerated as synthetic rubber are butadiene-styrene rubber (SBR), polybutadiene rubber (PBR), polychloroprene rubber (CR), butadiene-acrylonitrile rubber (NBR), polyurethane rubber, ethylene-propylene rubber, silicone rubber, rubber chloride, etc.

The lower peripheral portion of the upper 1, namely a portion of the first reinforcing member 3 and second reinforcing member 4 are integrally joined with the upper periphery of the sole 5, namely with the cover sheet G to form a joint portion of the athletic shoe. In the drawings, designated at 10 is a thread for stitching the upper and the sole together; at 11, sole core; and at 12 an intermediate sole.

The present invention is characterized in the structure of the lower peripheral portion of the upper 1, the upper peripheral portion of the sole 5 and the joint portions of both of these portions.

Since the upper member 2 of the upper in accordance with the present invention is formed of a tough cotton woven fabric such as canvas or of a Woven fabric of tough synthetic fibers such as polyamide resin fibers or polyester resin fibers, the upper is capable of satisfactorily `withstanding the tension forcibly exerted thereon by the i'oot of the wearer. However, as compared with other tthletic sports, wrestling, boxing or like sport produces ',uch an extremely high tensile force that the lower porion of the upper member 2 is liable to be torn.

Accordingly, to the lower peripheral portion of the lpper member 2 is adhered the first reinforcing member 5 made of a synthetic resin film or leather piece having yhe same quality as the synthetic bers forming the upper nember 2 or the upper member is provided, stitched hereto, with the first reinforcing member 3 made of a synthetic resin film or leather piece which is different i'rom the upper in quality. In addition, around the toe )ortion or the heel portion of the upper member 2 which s particularly susceptible to great damage or over the :Xternal surface of the first reinforcing member 3 corre- ;ponding to both of those portions, there is provided n adhesive or stitching engagement therewith, a tough second reinforcing member 4 such as a thick lfilm or eather piece of synthetic resin having the same quality ts the first reinforcing member 3 or a thick leather piece. l`hus constructed, the athletic shoe is not only capable Jf withstanding high tension exerted thereon by the vearers foot and frictional force produced upon contact vith a mat or the oor, but the reduction of the service ife of the shoe due to the 'breakage in the upper 1 alone :an be precluded.

Because the sole 5 comprises the cover sheet 6 and a ubber sole 7 to be brought into contact with the ground oined therewith, the cover sheet being formed of pieces )f cloth 8 and 8 of a tough cotton-fabric like canvas )r of a tough woven fabric 'made of synthetic fibers such 1s polyamide resin fibers forming the upper member 2 vith a thick rubber cement layer or rubber piece 9 inter- Josed therebetween, the rubber sole 7 including wear- 'esisting synthetic rubber or the like, the sole 5 can withytand compression and tensile forces forcibly exerted :hereon against possible breakage. With the damage to :he sole 5 thus precluded, the athletic shoe is made senvceable over a remarkably prolonged period.

Further due to the fact that the lower peripheral por- :ion of the upper 1, namely a portion of the first reinforcng member 3 and the second reinforcing member 4 are oined with the upper peripheral portion of the sole 5, lamely -with the cover sheet 6, or the former and the atter are stitched together after being joined, the joint aortions can sufficiently withstand high tensile and com.- viression forces forcibly exerted thereon by the foot of :he wearer, the joint portion between the upper periphery )f the sole 5 and the lower periphery of the upper 1 :bus being perfectly protected against possible destruczion. In case, for instance, the rst reinforcing member 3 1nd second reinforcing member 4 on the upper member Z of the upper 1 and cloth pieces 8, 8 of the cover sheet S of the sole 5 are formed with a material of the same quality, the connection at the joint portion can be made urther secured. Thus, there is no possible deterioration )f adhesion even when the joint portion is subjected to ;he perspiration exuded from the foot of the wearer. With effective reinforcement provided at the portion which is most susceptible to breakage, economical use )f material is ensured to exclude influence on production `It is required that the cloth pieces 8 and S, upper mem- Jer 2 of upper 1, first reinforcing member 3, second .'einforcing member 4 and the peripheral edge of sole 5 Je integrally stitched together with a thread passing there- :hrough In this case, the peripheral edge of sole 5 or :he lower periphery of upper 1 is cut by the thread which acts to prevent the destruction of the joint portion f sole and upper 1 against the tensile force exerted by 11e foot of the wearer. In accordance with the present invention, the lower periphery of upper 1, namly a portion of the rst reinforcing member 3, and S'eCOld reinforcing member 4 are joined with the upper perlphefy of sole 5, namely with the cover sheet 6 or they are 4 stitched together after being joined together, so that the thread is quite unlikely to cut the peripheral edge of the f sole or the lower periphery of the upper.
