The present invention relates to the elastic means of sports and recreational jumping shoes, and more specifically, to the front and rear of the main elastic portion consisting of a circular or elliptical plate spring, the secondary elastic portion having a large curvature improves the elastic force and even weight It relates to elastic means of jumping shoes for inducing dispersion.

Conventionally, there was a method of obtaining elastic force by vertically arranging a plurality of coil-type springs at the bottom of the shoe, but there was a problem that the elastic force of the spring was easily weakened when repeated use, and the center of gravity in the front, rear and left and right directions If it is tilted, not only the elastic force is weakened, but also has a problem that the risk of accidents is large because it is difficult to center.

In addition, in the Republic of Korea Utility Model No. 240627, two leaf springs are bent into an ellipse shape, and the front and rear ends of the upper and lower leaf springs are fixed through a connection fixing member made of a material such as rubber, and the connection fixing In the center of the member, a cushioning piece with strong elastic force is additionally provided to prevent the shock caused by excessive bending of the leaf spring, but a jumping shoe has been proposed. However, when the user jogs toward the front, the center of gravity This is inclined to the front, the configuration proposed in the utility model only when the center of gravity is inclined forward, there is a problem that the elastic force is weakened as compared to the vertical movement can not achieve the desired purpose.

In addition, the Republic of Korea Utility Model No. 265561 also proposed a configuration having an elastic plate coupled to the two leaf springs and extending from the front and rear ends of the shoe fixing body and connected to the lower leaf spring, but in this case as described above The same problem was not solved.

On the other hand, the two utility models are provided with a cushioning member in the center to prevent the collision of the upper spring and the lower spring due to excessive load, which is because the elastic force of the entire elastic means is not enough to collide with the upper and lower springs This proves the fact that there is a problem that the elastic force is not obtained enough to obtain a proper exercise and play effect.

The present invention devised to solve the above problems is provided with a secondary curvature having a large curvature in the front and rear of the main elastic portion made of a circular or elliptical leaf spring to improve the elastic force and induce even distribution of weight to increase the center of gravity It is an object of the present invention to provide an elastic means of a jumping shoe that does not weaken the elastic force even when tilted.

Elastic means for jumping shoes according to an embodiment of the present invention devised to achieve the above object, in the elastic means of the jumping juice to give elasticity to the jumping shoes for exercise or entertainment, elliptical shape of the leaf spring The upper main elastic portion having a plurality of fastening holes, and the lower main elastic portion having a buffer member at a bottom thereof; It is connected to the front and rear ends of the upper and lower main elastic portion, characterized in that it comprises a secondary elastic portion formed by bending in a circular shape.

In this case, the main elastic portion has an elliptic shape having a ratio of long axis to short axis of 2.5: 1 to 3: 1, the auxiliary elastic portion has a curvature of 10 times or more of the main elastic portion, and a diameter of 1/10 of the major axis diameter of the main elastic portion. It is preferable that it is the following circular shape.

The auxiliary elastic part may be formed by bending the leaf spring in two or more directions.

Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration and effect of the present invention.

1 is a plan view showing a configuration according to an embodiment of the present invention, illustrating a state in which the shoe 200 and the elastic means 100 is coupled. At this time, the shoe 200 may be used in any form coupled to the elastic means 100 according to an embodiment of the present invention, but the bottom surface is relatively solid, the fastening means 140 is enough to be coupled It is desirable to have a floor structure. In addition, as shown in Figure 2, the shoe fixing means 300 that can be fixed in a state that the user wearing a normal shoe may be combined with the elastic means (100).

The elastic means 100 according to the present invention can be largely divided into main elastic parts 110a and 110b and auxiliary elastic parts 120a and 120b, and the main elastic parts are again the upper main elastic parts 110a and the lower main elasticity. The part 110b and the auxiliary elastic part are divided into a front auxiliary elastic part 120a and a rear auxiliary elastic part 120a.

The main elastic portion (110a, 110b) may vary in size depending on the user's foot size, the length of the long axis should be determined to be greater than 10% larger than the size of the foot for safety and sufficient elastic force, the ratio between the long axis and the short axis is about 2.5 It is preferable to form an elliptical shape of about 1 to about 3: 1.

The upper main elastic portion 110a is provided with a fastening hole 150 to which the fastening means 140 for coupling with the shoe 200 is connected. Of course, it may be obvious that the fastening hole 150 may be integrally connected to the bottom of the shoe 200.

The bottom surface of the lower main elastic portion (110b) is provided with a buffer member 130 made of synthetic resin material to prevent slipping and to reduce the impact and noise caused by the collision with the ground.

The front and rear auxiliary elastic parts 120a and 120b have a curvature of 10 times or more than the main elastic parts 110a and 110b, and a diameter of 1/10 or less of the major axis diameter of the main elastic parts 110a and 110b, or It is preferably formed in an elliptic shape, and is connected between the upper and lower main elastic portions 110a and 110b from the front and the rear. The auxiliary elastic parts 120a and 120b not only serve to balance the elastic force when the user moves forward or backward through the center of gravity such as walking or running, but also to the elastic force of the main elastic parts 110a and 110b. In addition, it plays a role of strengthening the overall elastic force.

At this time, as shown in Figure 3, the auxiliary elastic portion (160a, 160b) may protrude toward the outer side of the main elastic portion (110a, 110b), but there is a problem that the size of the product unnecessarily large, it is illustrated in FIG. As described above, it is preferable that the main elastic parts 110a and 110b are bent into the inner side.

In addition, the auxiliary elastic part may be bent in two or more directions as illustrated in FIG. 4 or FIG. 5, but in consideration of manufacturing efficiency, the shape illustrated in FIG. 1 is most preferable.

The main elastic parts 110a and 110b and the auxiliary elastic parts 120a and 120b may be made of metal such as iron or stainless, and the main elastic parts 110a and 110b and the auxiliary elastic parts 120a and 120b. It is more preferable that the main elastic parts 110a and 110b and the auxiliary elastic parts 120a and 120b are integrally formed by a press mold or the like, rather than being separately manufactured and combined. In addition, a synthetic resin such as urethane may be coated on the surfaces of the main elastic parts 110a and 110b and the auxiliary elastic parts 120a and 120b.

The contents described in the drawings and the specification are exemplary descriptions of the present invention, which are merely used for the purpose of describing the present invention and are not intended to limit the scope of the present invention as defined in the claims or claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible from this. Therefore, the true technical protection scope of the present invention should be defined by the technical spirit of the claims.

The present invention configured as described above provides a useful effect that not only the elastic force is greatly improved than before by providing the auxiliary elastic part, but also sufficient elastic force can be secured even when the center of gravity of the user is inclined forward or rearward when walking or driving. .
