The present invention relates to an athletic shoe, and more particularly, to a shock absorbing structure and a device such as a running shoe having a foot member (hereinafter referred to as a water repellent member) and a spring member attached thereto and disposed below the foot receiving member. It is about.

More particularly, it relates to a shock absorber of such a shoe having a new structure for a spring member movably attached to the bottom of the foot receiving member.

Such athletic and athletic devices are known in the prior art as shown, for example, in US Pat. No. 4,492,374, issued to January 8, 1985, to Letman et al. However, the device disclosed in this US patent has several disadvantages.

1. Since the spring member is permanently attached to the foot receiving member, as shown in FIG. 1, the entire assembly unit should be performed near the inside of the assembled form, which must be inconvenient.

2. The plates 5, 7 forming the spring members are bonded to each other and the ratio and weight of the springs are arranged by the arrangement including the buckle 33, bar 35 and the circulating rubber member 39. It is attached to the regulating mechanism 13. Due to the nature of the attachment assembly, it cannot be disassembled automatically under abnormal force, which can be dangerous.

3. In the U.S. Patent No. 4,492,374 the device is relatively heavy because of the need for the metal members 13, 15, 17.

4. The ratio and weight adjustment mechanism 13 of the spring is burdensome and heavy.

It is therefore an object of the present invention to provide a structure for a spring member having a secure form.

It is a further object of the present invention to provide a spring member that can be completely separated from the foot receiving member so that the separating spring member can be stored in the foot receiving member.

It is also an object of the present invention to provide a device for adjusting the durability and weight of the spring member.

A band member having a first end and a second end comprising a second end and a second end of the top plate, a first fitting means at the first end of the band member and a second fit at the second end of the band member Fastening means; A first end of the lower plate and a first end of the upper plate to be fixedly accommodated in the first fitting means; And a second end of the lower plate and a second end of the upper plate, which are fixedly received by the second fitting means and are detachable to the bottom of the foot receiving member, by which the spring member can be automatically separated under an abnormal lateral force. It is a shoe cushioning device having a spring ratio and a weight adjusting device including a plastic spring member arranged to be attached.

The invention will be better understood by the following examples which are explained with reference to the drawings.

Referring to the drawings, the shock absorber of the athletic and athletic shoe shown generally in FIG. 1 comprises a foot receiving member 3 and a spring member 5. The foot receiving member can be suitably made as shown in US Pat. No. 4,492,374. Optionally it includes boots of some size, as shown in FIG. The spring member 5 comprises an upper plate 7 and a lower plate 9. The upper plate 7 and the lower plate 9 are both made of a rigid yet resilient plastic.

The upper plate 7 and the lower plate 9 are arcuate, so that when the spring member is dismantled, it becomes annular, ie oval. A spring rate and weight adjustment device comprising a plastic strap member 11 is disposed between the top plate 7 and the bottom plate 9. Heavier and thicker strap members 11 are used to provide greater resistance or to support more weight. Optionally, lighter and less thick plastic strip members are used to provide less resistance and to support less untitled material.

However, all of the above varieties are controlled at the production plant. In order to maintain an appropriate choice, retailers must have a large inventory.

According to a feature of the present invention, it is possible to reduce the need for such inventory by creating a plastic strip member 11 of material that can be reduced slightly by adjusting the spring ratio and the size of the weight adjustment device.

In accordance with a preferred form of the present invention, the strap member 11 includes a scale display portion 100 on at least one surface as shown in FIG.

When the strip member 11 is cut and detached according to the scale display part 100 so as to suit the needs of the user, the spring force and the weight may be adjusted because the force of the spring is reduced and the weight is also reduced.

The strap member 11 has a first end and a second end, the pad 13 is covered with the first end and the pad 15 is covered with the second end. Strip 17 is placed on pad 13 and strip 19 is placed on pad 15. In a preferred embodiment, the strips 17, 19 are in line with each other and are arranged at the center of each of the pads 13, 15. The upper plate 7 and the lower plate 9 have a first end and a second end. The recesses 21 and 23 are at the first and second ends of the upper plate 7, respectively, and the mating recesses 25 and 27 are at the respective first and second ends of the lower plate 9. . The width of the recess is such that the recess can be snap-fastened to each of the strips 17, 19. The recesses 21 are therefore fitted-fastened at the top of the strip 17 and the recesses 25 are fitted-fastened at the bottom of the strip 17. In the same way, the recess 23 is fitted-fixed on the top of the strip 19 and the recess 27 is fitted-fixed on the bottom of the strip 19. The connecting protrusions 29 and 31 extend at the first end of the upper plate 7, and the connecting protrusions 33 and 35 extend at the second end of the upper plate 7.

Similarly, the connecting protrusions 37 and 39 extend at the first end of the lower plate 9 and the connecting protrusions 41 and 43 (41 invisible in the drawing) extend at the second end of the lower plate 9.

When the spring member is dismantled, the connecting protrusion forms a boundary with each corner of the pads 13 and 15.

In FIG. 1, the first fitting fastening means 51, 54 and the second fitting fastening means 52, 53 provided on both sides of the strap member 11 are formed of the upper plate 7 and the lower plate 9, respectively. It is provided to hold each end.

The upper plate 7 is detachably attached to the foot receiving member 3 by screws 45 which are fastened through the upper plate 7 and the opening 47. Preferably the threaded bolt is mounted to the bottom of the foot receiving member 3 to receive the screw 45. The top plate 7 is therefore easily detached or attached from the foot receiving member 3. The sole 48 is detachably attached to the lower surface of the lower plate 9. The sole 48 is attached to the lower plate 9 by screws 49. Preferably, the threaded bolt is mounted to the plate to receive the screw 49. In operation, the top plate 7 is first attached to the foot receiving member 3 by screws 45 as described above. The recess 21 is then fitted-fastened to the top of the strip 17 and the recess 23 is fitted-fastened to the top of the strip 19.

The sole 48 is mounted to the lower surface of the lower plate 9 by screws 49 as described above. The recess 25 is snap-fastened to the strip 17, and the recess 27 is fitted to the bottom of the strip 19. The connecting protrusions 29 and 37 form a boundary with the right edge of the pad 13, and the connecting protrusions 31 and 39 form the boundary with the left edge of the pad 13. The connecting protrusions 33 and 41 are bounded by the right edge of the pad 15, and the connecting protrusions 35 and 43 are bounded by the left edge of the pad 15. The connecting projection only prevents the transverse movement of the upper plate 7 and the lower plate 9 with respect to the strap 11 and vice versa when under normal weak transverse force. However, a strong lateral force is applied (for example when the user steps on the edge of the sidewalk) and a strong lateral force allows the transverse movement of the upper plate 7 and the lower plate 9 to reverse. The holding suppression force of the connecting projections is exceeded. The snap fit of the concave and convex portion of the strap member 11 will then be returned to its original position and the entire unit will be dismantled and the strap 11 and the bottom plate 9 will fall off the top plate 7. Therefore, the user steps on a generally flat surface of the top plate 7, so that it can be prevented from falling or spraining the ankle. Automatic dismantling of the spring member under the influence of abnormal lateral forces provides safety that could not be used in the prior art.

The bottom of the sole 48 consists of a tread. Since such grounding acts when used, the detachably mounted sole can be replaced with a new sole when the previous sole is worn out and cannot be used.

The problem of the embodiment described above for detachably mounting the grounding portion to the bottom surface of the bottom plate 9 is that if a small screw is used, the force exerted when the device is used tends to pull the screw head through the sole and pull out the sole. Actually breaks away. The use of larger screws will be harmful to the bottom plate.

In order to overcome the above disadvantages, an apparatus of another embodiment is provided for releasably mounting the sole member on the bottom surface of the bottom plate. The arrangement is shown in FIGS. 3 and 4. In FIGS. 3 and 4 the first means 51 is provided for releasably supporting one end of the sole 48. The second means 53, which maintains a constant distance from the first means 51 by the space in which the sole is fitted, is provided for releasably supporting the other end of the sole 48.

In FIG. 4, the first means 51 has a first pocket 55 formed at one end of the bottom surface of the bottom plate and the second means 53 is formed at the other end of the bottom surface of the bottom plate. The two pockets 57 are constituted. Preferably, the means 51 and 53 and the sole 48 are made of the same rigid and resilient plastic as the rest of the spring member 5.

In FIG. 4, the sole 48 preferably has a stage 59 at one end and a stage 61 at the other end. The tiers are provided to prevent slipping of the sole in the pocket when arranged with respective ends in each pocket of the sole. In addition, the force applied to the bottom plate causes the bottom plate to expand and the traction force applied when the bottom plate is expanded causes a large stress in the center of the bottom plate. In order to alleviate this stress, the cutout 63 is drilled in the center of the lower plate, as shown in dashed lines in FIG.

The sole is easily inserted into the pocket by bending it and inserting each end of the sole into each pocket. The soles are then released and the springs return to their original form. In addition to being able to separate the spring member by an abnormal lateral force, it is also possible to separate the spring member only by hand force. Moreover, it is generally simple to separate the top plate 7 from the foot receiving member 3 when the unit is not used. All parts forming the spring member can be stored in the foot receiving member, as shown in FIG. Thus, the device of the present invention is much more portable than the device of the prior art.

In addition, since the spring member is made of plastic and no part is made of steel, the whole device is lighter than the device of the prior art, and the device is more portable.

Although specific embodiments have been depicted, this is intended to illustrate, but not limit the invention. Various modifications by the skilled person are possible within the scope of the invention as defined in the claims.
