Description

Detailed Description of the Invention a. FIELD OF THE INVENTION The present invention relates to shoes, and in particular to a cushion assembly for the rear part of a shoe. A shoe incorporating the cushion assembly according to the present invention exhibits a shock absorbing effect when the user is exercising and standing. The cushioning device also helps to provide the correct position for the foot.

B. PRIOR ART The present invention provides for the presence of a different type of material inserted between the upper and outer soles, or a cushioning insert made of a plastic material that is placed through or laterally through the rear portion of the sole. Unlike other known devices that rely primarily on the.

C. Means for Solving the Problems An important aspect of the present invention is that at least one spring is provided in the rear part of the shoe, between the outer sole and the upper sole which come into contact with the ground, preferably Is to insert multiple pins. The present invention will be further described below with reference to the accompanying drawings.

D. EXAMPLE In FIG. 2 of the accompanying drawings, the middle sole 5 is made of plastic or metal and has a thickness of about 0.3-0.8 cm. The intermediate shoe sole is provided with a retaining means for introducing the pin, that is, a plurality of anchoring holes, for example, screw holes.

The numeral 10 in FIG. 6 indicates an outer sole adapted to come into contact with the ground. This outer shoe sole is provided with a plurality of holes 11a at positions corresponding to the holes 11 provided in the intermediate shoe sole 5. Reference numeral 12 is an upper portion of the upper sole 6 that contacts the foot.

In FIG. 1, the pin 1 is a bottom part 2 made of a hard thermoplastic or rubber material and a means or tethering part which is engageable with the above-mentioned oil-retaining or tethering holes of the intermediate sole, for example the And an upper portion 4 which is threaded. The spring 3 is tightly arranged on the top part 13. 3 pins
Is a support for one function, namely a spring,
It is useful to have a hard part that contacts the ground and to be threaded to allow engagement with the midsole. This pin and spring assembly is shown at 7. The final position of the lower end of the spring is indicated by the arrow, which means that the spring rests in the groove 16 at the top of the threaded portion 4.

As shown in FIG. 2, reference numeral 5 is an intermediate sole provided with a screw hole 11. This midsole is made of plastic material or metal. This midsole accommodates the pins, serves to align the springs and provide strength to the areas where the cushioning action is exerted. In addition, this midsole compensates for slippage in the cushion assembly.

FIG. 4 shows the upper sole 6 provided with a plurality of protrusions or teeth 14. The teeth penetrate into the top portion of the spring so that the spring is held firmly in place after the shoe is assembled. The upper sole 6 holds the springs and prevents them from injuring the user's foot, but also provides strength to the cushion area and supplements the slip of the cushion assembly.

Reference numeral 10 in FIG. 6 is a conventional shoe sole provided with a hole 11a. These holes are of substantially the same size as the base 2 of the pin.

Reference numeral 9 in FIG. 6 represents another intermediate sole which can optionally be inserted under the upper sole 6. The midsole is preferably made of a low density foam material to help create a shock absorbing effect without creating drag. The midsole is provided with holes 11b, must have the same dimensions as these holes 11 and 11a, and are located at the positions corresponding to the holes 11 and 11a. The spring 3 can be made of different materials to have different strengths. This midsole 5 can be glued, sewn or attached to the outer sole by any suitable means. This midsole 5 provides the spring with the correct orientation and tilt angle, reinforces the cushion area, and a suitable inward tilt angle offsets slight or outward sliding of the assembly. The midsole can be made of metal or plastic material, can be rigid, can be made in one piece, or can consist of multiple parts.

The upper sole 6 with teeth can be glued, sewn or attached to the upper of the shoe by any suitable means. The upper sole holds the upper ends of the springs, which are also pressed against the toothed surface, thus eliminating skidding during use. The upper sole also reinforces the cushioning area and reinforces the material of the outer part of the foot to offset the skidding of the device and to provide a slight amount of inward incline.

The diameter of the holes may vary depending on the size of the shoe. It is not always necessary to have a specially designed device for each size or half size, but pre-drilled lower mid soles and toothed upper soles are used for each size. Good. The size and strength of the spring as well as the number of holes are determined by the weight defects to be supported or abnormal defects in the physical form to be corrected. The number of holes in the example shown is suitable for average size shoes 13
It is an individual. Smaller size shoes have fewer holes, and larger size shoes have more holes.

The total cushion force resulting from this assembly according to the invention is
It is the sum of the product of the elastic modulus of each spring and the number of springs, and the elastic modulus of the outer sole. FIG. 6 shows how the various parts are arranged. The pin can be screwed into place with a suitable screwdriver. The base of the pin may be circular or any other shape, such as hexagonal. If the pins become worn, they can easily be replaced on the spot.

One advantage of the shoe according to the invention is, for example, training,
It can be used as footwear for sports such as jogging, tennis, and football shoes, or any other shoe especially used for running or marching. Due to its shock-absorbing effect, the shoe minimizes illnesses such as inflammation, periosteitis, or any other acute or chronic illness. The number of springs and the position of the springs can be varied according to individual needs. The cushioned shoe according to the invention reduces fatigue, reduces muscle stress and protects the bones of the foot.
