Description

  The present invention belongs to footwear for health promotion.

  For example, when the muscles behind the knees are depleted and the knees bend due to lack of exercise or aging, the muscles of the thighs contract and the pelvis tilts backward. When the back of the pelvis is bent and the shoulders are rounded, the breathing becomes shallow and blood flow deteriorates. As a result, metabolism and immunity are lowered, and the autonomic nerve is also adversely affected. Further, the blood flow to the brain is reduced, which may impair cognitive function. Therefore, the inventor of the present invention has put into practical use a health appliance (for example, refer to “Patent Document 1”) that allows a user to stretch the back of his / her knee.

  On the other hand, Patent Document 2 discloses a sandal in which the back muscles such as the Achilles tendon, the back of the knee, and the calf are stretched just by wearing them. In the sandals (footwear), the bottom is formed with the tip of the toe in order to enhance the stretching effect. In this type of sandals, the slope of the bottom is set to 10 degrees or more from the heel to the tip of the toe, so it is easy for the user's knees to move forward while standing up, and the back of the knees tends to bend, distorting the entire posture. . Further, since the bottom has a large degree of inclination, it is not suitable as footwear when performing stretching.

  An object of the present invention is to provide a knee-back straightening sandal capable of easily stretching the back of the knee while maintaining a correct posture.

  In order to solve the above-mentioned problems, the present invention is a sandal in which a sole contacting surface at the bottom with which a user's sole contacts is inclined from the heel to the tip of the toe, and the slope of the sole contacting surface is 3 degrees. It is characterized by

  According to the present invention, it is possible to provide a knee-back straightening sandal capable of easily stretching the back of the knee while maintaining a correct posture.

It is a top view of the back knee sandals concerning this embodiment. It is a top view of the bottom part of the back knee sandals which concerns on this embodiment. FIG. 3 is a sectional view taken along line AA in FIG. 2. It is explanatory drawing of a wall pushing operation. It is explanatory drawing of a leg opening operation. It is an explanatory view of wall contact operation.

An embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a plan view of an inflatable knee sandal 1 (shown only for the right foot) according to the present embodiment. In addition, the back knee sandals 1 for the right foot are bilaterally symmetrical with the back knee sandals for the left foot. Therefore, only the sole extension sandal 1 for the right foot is illustrated, and the illustration of the sole extension sandal for the left foot is omitted.

  As shown in FIG. 1, the back knee extension sandal 1 includes an instep covering portion 3 that covers the instep of the user 10 (see FIG. 4), and a bottom portion 11 that supports the sole of the user 10. The back knee sandals 1 are made of, for example, foamed resin, and the instep portion 3 and the bottom portion 11 are integrally (simultaneously) molded. The instep cover 3 is divided into an outer instep cover 4 extending from the outside of the bottom 11 and an inner instep cover 5 extending from the inside of the bottom 11. The inner instep portion 5 is bifurcated in a portion that is superposed on the outer instep portion 4, and has belts 6 and 7, respectively. On the other hand, the outer instep portion 4 is provided with buckles 8 and 9 corresponding to the belts 6 and 7. Then, by operating the belts 6 and 7 and the buckles 8 and 9 to adjust the circumferential lengths of the front side and the back side of the instep portion 3, the back of the knee extension sandal 1 is adapted to the feet of various instep widths and instep heights. Can be made.

  In addition, although the instep part 3 and the bottom part 11 are integrally formed in the present embodiment, the manufacturing method of the knee back stretched sandal 1 is not limited to this, and the outer instep covers individually made. You may provide the process of integrating the part 4, the instep cover part 5, and the bottom part 11.

  Referring to FIG. 2, the sole contact surface 12 of the bottom portion 11 is provided with a raised portion 13 extending in the left-right direction along the base of the toe of the user 10. Further, the sole contact surface 12 is provided with a raised portion 14 extending from the raised portion 13 between the first toe (thumb) and the second toe (index finger) of the foot of the user 10 toward the toe. Further, the sole contact surface 12 is provided with a plurality of (“two” in the present embodiment) raised portions 15 and 16 for stimulating acupuncture points (for example, “spring”) of the sole of the user 10. Further, an inclined portion 17 that is inclined along the soles (bellys of the toes, heels) of the user 10 is provided on the periphery of the sole contact surface 12.

  Referring to FIGS. 2 and 3, the slope of the sole contact surface 12 of the bottom 11, that is, the inclination angle θ of the design of the sole contact surface 12 (the base line L shown in FIG. 3) is from the heel to the tip of the toe. It is set to 3 degrees. As described above, in the back of the knee sandal 1, the sole of the user 10 is slightly raised forward by setting the inclination of the foot contact surface 12 to 3 degrees from the heel to the tip of the toe. As a result, the back of the knee of the user 10 is unconsciously stretched (to the extent that the user 10 does not feel it). As a result, the user 10 can have an ideal posture and walking style only by wearing the stretched back sandals 1.

In addition, the user 10 can further enhance the knee back distraction effect (knee back stretch effect) by performing the following operation while wearing the knee back straightening sandals 1.
(Wall push operation)
The user 10 extends his back and stands in front of a wall (not shown). Next, the user 10 opens his / her legs back and forth to extend the back of the knees of the hind legs, bends the knees of the front legs, and extends both hands forward at shoulder level to attach to the wall. Then, as shown in FIG. 4, while pushing the wall with both hands and stepping on the floor with the heel, it takes a few seconds to expel all the air in the lungs. Next, the front and back of the legs are replaced and the above operation is repeated.

(Opening leg movement)
The user 10 stands with both legs open outward. At this time, open the toes of both feet at 45 degrees. Next, after inhaling a large amount of breath, with your back stretched out, slowly and straightly lower your hips while exhaling. Here, by lowering the waist deeper, the muscles that support the pelvis can be trained. As a result, the lower half of the body is strengthened, and the effect of distraction of the back of the knee can be improved. Further, as shown in FIG. 5, by striking the thigh with the waist lowered, adrenaline is secreted to activate the brain and prevent dementia.

(Wall contact operation)
The user 10 stands with his / her heel, waist and back attached to a vertical wall (not shown). As a result, the three points of the heel, the waist, and the back are aligned with each other, and the back of the knee can be stretched firmly in combination with the effect of extending the back of the knee of the knee back stretching sandal 1. In this state, the palm distracting effect can be enhanced by attaching the palm to the wall and exhaling. Further, as shown in FIG. 6, the trunk muscle can be trained by returning the palm and attaching the instep to the wall, and exhaling in this state and holding for a certain time (for example, “5 seconds”).

The effects of this embodiment will be described.
Conventionally, a sandal whose bottom portion is inclined to the tip of the toe for the purpose of promoting health is set to have a foot contact surface with a slope of 10 degrees or more. Therefore, in the sandals with the tip of the toe raised, the knee of the user 10 is likely to move forward while the user stands up, the back of the knee is bent, and the entire posture is easily distorted.

Therefore, in the knee-back stretch sandal 1 according to the present embodiment, the slope of the sole contact surface 12 is set to 3 degrees. As a result, the soles of the feet of the user 10 are slightly raised, and the soles of the knees of the user 10 are stretched unconsciously (to the extent that the user 10 does not feel). As a result, the user 10 can have an ideal posture and way of walking only by wearing the knee-back straightening sandals 1.
Then, by extending the back of the knee and adjusting the posture, blood flow is smoothed, metabolism is increased, immunity can be improved, and autonomic nerves can be adjusted. Furthermore, since the blood flow to the brain increases, it is possible to suppress the decline in cognitive function.
Further, according to the present embodiment, since the raised portion 13 that extends along the base of the toe of the user 10 is provided on the sole contact surface 12 of the bottom portion 11, the toe movement (kicking) during walking. Can support.
Further, according to the present embodiment, on the sole contact surface 12 of the bottom portion 11, the raised portion 14 extending toward the toe between the first toe (thumb) and the second toe (index finger) of the foot of the user 10. Since it is provided, the hallux valgus can be corrected.
Further, according to the present embodiment, since the sole contact surface 12 of the bottom portion 11 is provided with the raised portions 15 and 16 that stimulate the foot pot, various disorders of the body (internal organs) can be improved.
Further, according to the present embodiment, by performing various operations in a state where the knee-back stretch sandal 1 is worn, the knee-back distraction effect (knee-back stretch effect) can be further enhanced.
