Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is easy to walk with no difficulty in carrying the foot, and footwear such as general shoes, sandals, and footwear for persons with disabilities that are required to relieve the sole stimulation against pushing up from the ground surface. Regarding the bottom.
[0002]
[Prior art]
In general, most footwear soles are made of natural leather, synthetic leather, urethane rubber, etc., including a piece that is integrally molded or bonded, and leather soles, non-woven fabrics using polypropylene as a binder, hard soles made of hard urethane rubber, etc. It is the structure which laminated | stacked.
[0003]
Although the footwear using the footwear having such a structure has a slight shock absorption, the footwear is hard to touch when worn, and it is hard to walk. There is a discrepancy between the deformation mode of the footwear sole at the time of gait and the movement mode of the foot adapted to the force on the toe part of the foot, the base of the finger, the front foot part, the arch part, and the heel part, which acts at the time of weight transfer, This is a factor in the inhibition of weight shift and increased pain and walking fatigue due to smooth and stable walking gait.
[0004]
In particular, the inhibition of weight shift due to smooth and stable walking gait is inappropriate as the bottom structure of footwear for persons with disabilities including persons with injuries and sequelae that are difficult to balance, and improvements are desired. .
[0005]
[Problems to be solved by the invention]
The present invention comfortably deforms and adapts to a state that approximates the movement mode of the foot that adapts to the force acting on the toe part of the foot, the base of the finger, and the front step part during weight transfer by walking gait. In both cases, it is possible to provide a footwear sole that can greatly reduce pain and walking fatigue by gentle contact with the sole front part with different hardness and mitigating against a push-up from the contact surface. Let it be an issue.
[0006]
[Means for Solving the Problems]
The footwear sole according to the present invention is a footwear bottom obtained by laminating and bonding a grounding bottom (10) and an insole (20) , which solves the above-mentioned problems , and its configuration will be described below.
[0007]
The footwear sole according to the present invention is between the ground contact bottom (10) and the midsole (20), and the entire area of the buttocks region (H) including the arch portion (1) has a cushioning piece (30 In the footwear bottom formed by laminating the grounded bottom (10) and the midsole (20) with the inclined surfaces of the constituent members bonded together to form the grounded bottom (10) , the grounded bottom (10 the configuration), toe piece of rigid (11), the claw destination piece (11) softer before step parts pieces (12), the toe piece includes arch portion (11) and the hardness of the comparable heel piece (13) but before step parts piece (12) ground plane bottom and cross-sectional positive trapezoidal inclined adhesive surface formed by the inclined side portion adhesive surface of the cross formed to correspond to (14) of The structure of the insole (20) is connected to the punched hole (21) penetrating in the central region of the portion overlapping the front step piece (12) of the grounded bottom (10). The front pedal cushion body (22), which is softer than the hardness of the bottom (20) member, protrudes from the surface of the midsole (20). The buttock cushioning piece (30) is formed of a cushion member formed of a wedge-shaped section (32) having a gradually reduced thickness from one end of the interposed main body (31) toward the arch. It is characterized by that.
[0008]
【The invention's effect】
According to the configuration of the footwear sole according to the present invention , the hard toe part (4), the softer tread piece (12) and the heel part piece (13) having the same hardness as the toe piece piece (11). The ground contact bottom (10) formed by the above-mentioned is adhesively connected by an inclined adhesive surface (14) formed by an inclined side portion having a regular trapezoidal cross section with the ground contact surface of the front tread piece (12) as a base, and the contact The front foot cushion body (22) that is softer than the hardness of the midsole (20) member is inserted into the punched hole (21) that penetrates the center region of the part that overlaps the front foot piece (12) of the ground floor (10). The toe part piece (11) of the foot during weight transfer by walking gait required by the toe part region (T) as a footwear bottom by fitting and adhering so as to protrude from the surface of the insole (20) It is possible to deform and adapt to the state of movement of the foot that adapts to the force acting on the base of the finger and the front tread piece (12) without difficulty, and to adapt the soft front tread cushion body (22). Contact with the front foot part due to hardness difference due to protrusion The gently that makes it possible to exhibit the relaxation function with respect to the push-up or the like from the ground plane.
[0009]
In addition, a wedge-shaped section (32) having a thickness gradually reduced from one end of the interposed main body (31) toward the arch piece (11) between the buttock stacks of the insole (20) and the grounded bottom (10). ) And the buttock cushioning piece (30) formed in the above, the buffer function from the arch to the heel is also exhibited.
[0010]
Furthermore, the footwear sole according to the invention of claim 2 is a leather board, a non-woven fabric using polypropylene as a binder, a hard urethane rubber, and a hard part of the heel region (H) or the grounded bottom (10) and the midsole (20). Any of the above, the front cushion part (22) and the buttocks cushioning piece (30) fitted and bonded to the toe part region (T) or the midsole (20), cork, sponge, rubber sponge, felt, Because it is made of either poly-norbornene rubber or polyurethane foam, it has excellent impact resistance and is deformed by the continuous addition of body weight. It is possible to contribute to the provision of comfortable footwear.
[0011]
In the footwear sole according to the third aspect of the present invention , the front foot cushion body (22) to be fitted and bonded to the hole (21) of the insole (20) has the contour of the hole (21). By adopting a shape having a similarly formed heel part, the hardness change at the boundary part with different hardness becomes gradual, and the uncomfortable feeling of contact with the sole can be eliminated.
