Technical Field

The utility model relates to a double-layer sole and a shoe, in particular to a replaceable double-layer sole and a shoe.

Background Art

Currently, most of the shoes and boots on the market and the military combat training shoes and boots have the upper and soles tightly integrated together. However, for military training shoes, long-term training will cause great wear and tear on the soles, but the uppers are relatively strong. If you buy a new pair of shoes, it will not only cause waste, but the feet and the new shoes will also need to be run-in to improve the comfort of wearing. If you don't change your shoes, the anti-slip pattern on the soles will not have an anti-slip effect, affecting the safety of training.

In the prior art, there are already shoes and boots with replaceable soles. The detachable structures are basically deformable blocks and groove structures. However, the disadvantage of this structure is that during training, the soles are constantly rubbed against the ground due to continuous running and jumping. When too much force is applied, the deformable material will deform and tend to separate from the original sole. Repeatedly doing this will easily cause the detachable sole to be loosely connected to the original sole.

DETAILED DESCRIPTION

The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.

Embodiment 1 A replaceable double-layer sole

As shown in FIG1 , this embodiment includes a fixed sole 1 and a replacement sole 7. The fixed sole 1 is used to be fixedly connected to the upper 12, i.e., the structure of a common sole in the prior art, but the bottom of the fixed sole 1 is not provided with anti-skid patterns, and the bottom is a flat structure. The replacement sole 7 is detachably arranged on the fixed sole 1, and the side of the replacement sole 7 connected to the fixed sole 1 is a flat surface, and the side contacting the ground is provided with anti-skid patterns.

A hard block structure is built into the arch of the fixed sole 1. The block structure is made of acrylic, PVC or ABS hard plastic. PVC is used in this embodiment. The block structure does not directly contact the sole of the foot. The fixed sole 1 is made of a softer rubber material. Therefore, the thickness above the block structure is sufficient to buffer the impact of the hard material. In addition, the block structure is set at the arch of the foot. The foot pit at the arch of the foot is arched upward, and the contact with the block structure is relatively small. Therefore, it does not affect the comfort of wearing.

As shown in FIG2 , a circular groove 2 is provided on the block structure at the arch of the fixed base 1, and a slot 3 is provided on the inner wall of the circular groove 2, that is, it is recessed inward along the inner wall of the circular groove 2 at a position 3 mm deep from the end face of the circular groove 2, and the slot 3 is arranged around the inner wall of the circular groove 2. The thickness of the slot 3 is 4 mm, 5 mm or 6 mm, and 5 mm is used in this embodiment. At least two jacks 4 are provided at the notch of the circular groove 2. Two jacks 4 are provided in this embodiment, and the two jacks 4 are arranged oppositely, and the straight line where the two jacks 4 are located is perpendicular to the length direction of the fixed base 1. The jack 4 extends downward from the end face of the slot 3 to the slot 3, is connected with the slot 3, and one end is connected with the cavity of the circular groove 2. The fixed sole 1 is provided with an arc-shaped groove 5 with the circular groove 2 as the center at the forefoot and the heel. A plurality of arc-shaped grooves 5 are arranged at intervals. The arc-shaped grooves 5 all penetrate from one side of the fixed sole 1 to the other side, and the notches of the arc-shaped grooves 5 are all smaller than the groove bottom. The notch refers to the position of the opening, and the groove bottom refers to the bottom opposite to the notch.

As shown in FIG3 , a protrusion 8 is fixedly provided at the arch of the replacement base 7. The position of the protrusion 8 corresponds to the position of the circular groove 2. The protrusion 8 matches the circular groove 2 and is inserted into the circular groove 2. When the bottom of the protrusion 8 contacts the bottom of the circular groove 2, the replacement base 7 is tightly fitted with the fixed base 1. Two plug-in blocks 9 are fixedly provided on the protrusion 8. The two plug-in blocks 9 are arranged opposite to each other, and the straight line where the two plug-in blocks 9 are located is consistent with the length direction of the replacement base 7. Both plug-in blocks 9 are fixed at 3 mm from the end where the protrusion 8 is connected to the replacement base 7. The thickness of the plug-in blocks 9 matches the thickness of the slot 3, and the thickness is slightly less than 5 mm, so that the plug-in blocks 9 enter the slot 3 through the insertion hole 4. The replacement base 7 is rotated so that the two plug-in blocks 9 slide in the slot 3 to a position perpendicular to the straight line where the two insertion holes 4 are located, so that the replacement base 7 is tightly fitted with the fixed base 1. When the replacement base 7 and the fixed base 1 are perpendicular to each other, the positions of the plug-in blocks 9 and the insertion holes 4 are the same. When the replacement base 7 and the fixed base 1 overlap each other, the positions of the plug-in blocks 9 and the insertion holes 4 are staggered. The replacement base 7 is provided with an arc-shaped convex rib 10 matching the arc-shaped groove 5, wherein the arc-shaped convex rib 10 closest to the protrusion 8 extends from the center of the replacement base 7 to both sides, but does not extend to both sides of the replacement base 7, and the remaining arc-shaped convex ribs 10 extend to both sides of the replacement base 7. The material of the protrusion 8 and the insert 9 in this embodiment are both hard plastic material, which can be acrylic, PVC or ABS hard plastic, and the present embodiment adopts PVC material, and the arc-shaped convex rib 10 is an elastic material, and the present embodiment adopts rubber material.

In order to further improve the firmness of the connection, the front end and the rear end of the fixed base 1 are both provided with a concave hole 6, and the corresponding positions on the replacement base 7 are fixed with a positioning block 11 matching the concave hole 6. The positioning block 11 is made of elastic material, and this embodiment uses rubber material. Alternatively, the front end and the rear end of the fixed base 1 are both provided with a positioning block 11, and the corresponding positions on the replacement base 7 are both provided with a concave hole 6 matching the positioning block 11. The cooperation between the two adopts the existing technology. This embodiment adopts the first structure.

As shown in FIG4, when using this embodiment, the replacement sole 7 is placed vertically with the fixed sole 1, so that the plug block 9 on the protrusion 8 of the replacement sole 7 corresponds to the plug hole 4 on the circular groove 2 of the fixed sole 1, and then the plug block 9 is inserted into the plug hole 4, and the replacement sole 7 is rotated to make the plug block 9 rotate in the slot 3 of the circular groove 2. At the same time, the arc convex rib 10 on the replacement sole 7 enters the arc groove 5 on the fixed sole 1. When the replacement sole 7 and the edge of the fixed sole 1 coincide with each other, the rotation is stopped. At this time, the plug block 9 is tightly inserted in the slot 3, and the replacement sole 7 is closely attached to the fixed sole 1. The plug block 9 on the protrusion 8 of the replacement sole 7 and the plug hole 4 on the circular groove 2 of the fixed sole 1 are mutually offset to play a limiting role, and the arc groove 5 and the arc convex rib 10 are mutually limited, which further plays a role of tightly fixing to prevent loosening. Finally, the positioning blocks 11 at the front and rear ends of the overlapped replacement sole 7 are pressed into the concave hole 6 of the fixed sole 1, so that the entire sole is tightly connected in the front, back, left, right, up and down positions, which greatly improves the firmness of the combination of the two.
