Description

  The present invention relates to the elastic structure of footwear, and more particularly to the elastic structure of footwear having greater elasticity.

  There are many elastic structures of footwear. First, as an example, a small balloon-like elastic body filled with air is installed at the bottom of footwear (shoes), and the scientific success is pursued based on the mechanism that takes weight when people use it. There is an example with a structure that contains it. As another example, there is an example in which an elastic foam member having resilience is used on the bottom of the footwear to form a structure. The footwear having the elastic structure described above is comfortable both when walking and running and sufficiently satisfies each purpose of use. However, there is no footwear that satisfies both the conditions that both have an unprecedented elasticity and can be used normally in daily life. Therefore, as an example of footwear having a large elasticity, there is an open patent publication (A) JP-A-6-189801. This is a jumping shoe invented by renowned inventor Dr. Nakamatsu. This structure is strong enough to jump high, but does not gain citizenship as a daily product because of its special purpose.

  An invention similar to the present invention is disclosed in Japanese Patent No. 1516. However, the elastic structure of the present invention mainly uses the elasticity of the umbilical cord member, so that there is a structural problem that cannot generate strong elasticity. Can be mentioned. The elastic structure of the footwear according to the present invention is expected to improve such a conventional elastic structure and technical advancement.

Means for the idea to solve the problem

  The invention described in claim 1 is a footwear having elasticity in the heel portion of the footwear, wherein two or more plywood members constituting the foot are pasted together in an open state toward the rear of the footwear.

  The invention according to claim 2 has elasticity in the heel portion of the footwear according to claim 1, wherein an elastic body is provided in a gap generated between two or more plywood members constituting the footwear in the structure of the footwear base. It is footwear.

  The invention according to claim 3 is the structure of the footwear base, wherein the plywood material forming the base is connected from the front to the rear diagonally upward, the height of the heel portion is the apex, and the plywood material is curved toward the bottom of the footwear. Is a footwear having elasticity in the heel portion of the footwear formed in a continuous shape.

  A structure in which two or more plywood members constituting a footwear base are opened to the rear of the footwear produces a spring effect, and when walking with footwear having this structure, a large elasticity is generated in the heel portion. Moreover, by providing an elastic foam member having the properties of shrinkage and restoration in addition to the structure together with the structure, the elasticity transmitted to the foot changes, and by adjusting the amount of elastic foam member and the repulsive stress, The elasticity applied to the heel part is transmitted appropriately.

  This will be described below with reference to the drawings. First, FIGS. 1-12 is a side view showing the structure of the footwear of this invention shown from the perspective view of FIGS.

  1 and 2 (see perspective views of FIGS. 16 and 17) are side views showing the basic structure of the footwear of the present invention shown in claim 1. The A plywood and B plywood shown in the side view are opened from the base point (hereinafter abbreviated as “base point”) to which each plywood material opens, and A is warped upward, and B is parallel to the ground.

  The material of the plywood material constituting the footwear base of the present invention is suitably a material having strong elasticity such as a natural wood plywood, a bamboo plywood, or a synthetic resin plywood. The material of the plywood material listed above is not limited to a single material, and may be a united member formed by a combination of various materials, or any member having a leaf spring property. The feature of the present invention is that the elasticity of the plywood is applied to the footwear, and the two elements for bending the plywood and the construction of the footwear base are indispensable for producing elasticity.

  Next, the drawings shown in FIGS. 3 and 4 (see the perspective views of FIGS. 18 to 19) have basically the same structure as FIGS. 3C plywood is formed between the plywood of FIG. 3A and the plywood of FIG. 3B. 4D is formed by connecting the rear ends of the plywoods shown in FIGS. 3A and 3C.

  The above-described elastic structure shown in FIGS. 3 and 4 is the same as that of FIGS. 1 and 2 as a basic structure. However, since one plywood material is formed, the ability to limit the stress with respect to the load from the upper part is formed. Becomes higher. For example, it is effective as a measure for people with heavy weights and as a measure for running, and solves structural problems as a measure against a heavy load.

  Next, FIGS. 5 to 8 (see the perspective views of FIGS. 20 to 23) will be described. These are structural examples shown in claim 2, in which an elastic foam member is provided while the A plywood material and the B plywood material are opened rearward of the footwear. Next, it demonstrates in order.

  FIG. 5 (see FIG. 20 perspective view) is a structure in which an E-elastic foam member is provided over a short distance from the base point where the A-plywood material and the B-plywood material open to the rear of the footwear. 6 (see FIG. 21 perspective view) is a structure in which an E elastic foam member is provided from the rear end portion of the A plywood material to the rear end portion of the B plywood material in the same manner. FIG. 7 (see the perspective view of FIG. 22) is a structure combining the structure of FIG. 5 and the structure of FIG. FIG. 8 (see the perspective view of FIG. 23) is a structure in which an E elastic foam member is provided on the whole while the A plywood material and the B plywood material are opened.

  The reason why E elastic foam member is provided in Fig. 5 is that this part has soil and pebbles entering when walking with the footwear of the shape, it can not be solidified and the pebbles are fixed and the elasticity of the plywood material functions This is to solve the problem of not going to.

  The relationship between the elasticity of the A plywood material and the B plywood material and the elastic foam member in the examples of FIGS. 6, 7, and 8 is an elastic foam member having a repulsive stress as a role of reinforcing the elasticity of the A plywood material. It is essential to provide For example, in the case of the E elastic foam member of FIGS. 6, 7, and 8, if the elasticity of the A plywood material is insufficient, a type of E elastic foam member that matches the rebound stress of the E elastic foam member in accordance with the elasticity according to the manufacturing purpose select. The E elastic foam member has a difference in the repulsion stress of the product depending on the difference in the expansion ratio and the type of the resin material, etc., but each footwear structure is selected in light of the properties of the member according to various conditions.

  9 to 12 (see perspective views of FIGS. 24 to 27) will be described. These figures are all side views given as examples with respect to claim 3. The structure shown here is commonly characterized in that it is composed of a continuous structure of plywood and produces a leaf spring effect, which is different from the structure of claims 1 and 2 above. These will be described in order.

  The curved plywood material can be bent due to the nature of plywood, and the plywood material has a strong bending strength because it is a multi-layer, and has a strong elasticity. The leaf spring effect generated by applying this property to the bent portion in FIG. 9 results in greater elasticity at the heel.

  11 is not a structure having a curve, but a member to which two plate-like materials are fixed. When the material of the plywood shown in FIGS. 11A and 11B is a natural material such as wood or bamboo, bending is difficult and there is a problem in strength.

  FIG. 10 shows an example of a structure in which an elastic foam member is fixed to a plate-like material located in the rear part of the footwear in the structure shown in FIG. In the example shown here, the elasticity of the E elastic foam member is added to the elasticity generated in the A-plywood material shown in FIG. FIG. 12 is an example in which an elastic foam member is similarly provided on a plywood material located in the rear part of the footwear having the structure shown in FIG. As described above, the various structures constituted by the continuous hard plate-like material are simple, and there is an advantage that the manufacturing cost is reduced due to the structure of the members.

  13, FIG. 14 and FIG. 15 show other embodiments. In this example, an elastic body is provided at the bottom of the footwear, and the structure has an effect of reducing the impact caused by elasticity.

  In the present invention, the footwear platform refers to the structure of the lower part of the foot located on the sole of the footwear, and is referred to as the footwear platform for shoes, boots, sandals, etc. as well as clogs.

  In the present invention, a plywood material is not limited to a plate material joined with wood layers, but refers to a multi-layer material made of bamboo, natural materials, synthetic resins, metals, and other general materials. It also includes plywood that combines different types of materials.

  In the present invention, an elastic body refers to a member that has a property of contracting or deforming but restoring its original shape. Specifically, it refers to an elastic foam member, natural rubber or synthetic rubber, synthetic resin, metallic spring, etc., and all members having this property.
