Description

  The present invention relates to footwear such as shoes, sandals, and the like, and particularly to footwear having a walking promoting effect that can obtain a so-called rapid walking state by using it without requiring special training and proficiency. .

  Sports shoes and other so-called health sandals have been devised in various ways to contribute to health maintenance and promotion through walking, jogging and running. Specifically, the structure and material of the footwear sole are improved. However, many of these focus on improvements that take the unnatural form to train the muscle strength of the legs or make effective use of the legs in running competitions. In other words, most proposals are for training purposes, and there are almost no footwear that can be used for efficient walking even when used by ordinary people without any proficiency or training in daily life or daily work. Not proposed. The tasks that require a relatively quick action in daily operations are medical work sites or security / security sites, etc. It was assumed that the footwear could be used, and there were few footwear suitable for such purposes.

Utility model registration No. 3126681

  The present invention has been made in consideration of such a background, and can be used to receive support that allows the foot to be stepped forward naturally only by using it without special training and proficiency. The technical challenge is to develop new footwear that can provide a natural feeling when not in a walking state.

The footwear having a walking promoting effect according to claim 1, wherein the footwear includes an upper having an appropriate footwear structure and a sole provided on the lower surface of the upper, and the sole includes a sole that forms a ground contact surface, It comprises an insole provided between the main bottom and the upper, and the front lower surface of the main bottom is formed with a raised portion that is separated from the ground surface in a stationary state, The insole includes a shape retaining sole that suppresses deformation due to a compressive load, and a cushion sole that is prominently deformed due to a compressive load provided on the lower surface side of the shape retaining sole. A stepping guide fulcrum projecting downward is provided at a substantially intermediate portion, and a front cushion sole and a heel side cushion sole constituting the cushion sole are arranged before and after the stepping guide fulcrum. , Still above the heel side cushion sole incorporates repulsion spring acting in the compression direction, by the ground of the heel during walking, rebound spring is compressed, repelled by the subsequently weight shift instantly The spring for spring is restored to push up the heel, and the stepping-out guide fulcrum is the fulcrum of the swinging motion. It consists of features.

  Further, the footwear having a walking promoting effect according to claim 2 is characterized in that, in addition to the requirement of claim 1, the shape retaining sole is formed by integrally forming a stepping guide fulcrum.

  Furthermore, in the footwear having the walking promoting effect according to claim 3, in addition to the requirement according to claim 1 or 2, the bottom bottom has a lifting height dimension G on the tip side when the footwear is in a stationary state. Is a dimension in a range of 0.5 to 1.0 times the sole rear end height dimension H.

  Furthermore, the footwear having the walking promoting effect according to claim 4 has the lift length dimension L between the lifted portion starting point P and the tip of the lifted portion in addition to the requirements of claim 1, 2 or 3, It is characterized by having a size in the range of 1.0 to 2.5 times the floating height G.

  First, according to the first aspect of the present invention, the movement of the foot part in the walking motion is supported as if it had a seesaw-like movement, and the seesaw-like action is expressed with respect to the ground contact by the buttocks. A spring for repulsion acts, and after that, the footwear is lowered forward with the stepping guide fulcrum at the center, resulting in a situation where the foot is naturally stepped forward, thereby promoting walking. . In addition, even during standing work without walking, the sinking of the heel portion is suppressed by the repulsion spring, and a stable posture can be obtained.

  According to the second aspect of the present invention, the step-out guide fulcrum is formed integrally with the shape-retaining sole, which is excellent in strength and can be manufactured at low cost.

  Furthermore, according to the third aspect of the present invention, since the tip of the bottom is sufficiently lifted, when the body weight moves smoothly from the fulcrum supporting the body weight during walking, Is achieved and a state where the foot is naturally stepped on is obtained.

  Further, according to the invention of claim 4, since the lifted length dimension L is set to about 1.5 to 2.5 times the lifted height dimension G along with the deformation of the front cushion sole, The kick-out work is performed smoothly.

It is explanatory drawing which shows the effect | action aspect in the walk operation | movement of the footwear which has the walk promotion effect of this invention. It is a disassembled perspective view which shows the other Example of the footwear which has the walk promotion effect of this invention.

  The form for implementing this invention is as showing in the Example described below, Furthermore, the various form which can be improved within this technical thought is included.

  Hereinafter, the present invention will be described in detail based on illustrated embodiments. Reference numeral F denotes the footwear of the present invention, which has a walking promoting effect during normal walking. The footwear F is roughly configured by combining the upper 1 and the sole 2, and the upper 1 is a shoe type upper 11 as shown in FIGS. A sandal type upper 12 or the like having an appropriate wearing structure can be applied. Of course, in addition to this, it is naturally possible to adopt a form suitable for the purpose, such as a boot type and a slipper type.

  Next, the sole 2 having the main configuration of the present invention will be described. The sole 2 includes a bottom bottom 20 that constitutes a ground contact surface according to a conventional method, and a midsole 21 provided between the bottom bottom 20 and the upper 1. The bottom 20 is designed in consideration of durability, anti-slip properties and the like at the time of ground contact, and a flat rubber rubber or the like having an appropriate non-slip structure is formed on the ground contact side. In the completed state, the sole 20 is configured such that the toe side does not come into contact with the shoe F in a stationary state.

  On the other hand, the insole 21 includes a shape retaining sole 22 and a cushion sole 23, and further a rebound spring 25 incorporated therein. The shape-retaining sole 22 is made of a material that suppresses deformation due to a compressive load, and specifically, a molded member such as hard urethane is used. As a whole, this has a substantially flat plate shape, and the shape of the outer shell substantially matches the outer shape of the shoe. In this shape retaining sole, a step-out guide fulcrum 220 protruding downward is formed at a substantially intermediate portion in the foot length direction, a heel support portion 221 is formed at the rear, and a front support portion 222 is formed at the front. It is formed.

  The heel support portion 221 and the front support portion 222 each have a smoothly continuous curved surface at the boundary portion reaching the step-out guide fulcrum 220. In other words, the upper and lower thickness dimensions of the heel support portion 221 and the front support portion 222 are such that the thickness is gradually increased from the front and rear ends toward the step-out guide fulcrum 220. In addition, about the shape retention sole 22 in which the deformation expression due to the compressive load is suppressed, it is needless to say that if the compressive load is applied, the corresponding compressive deformation will occur. In other words, it means that the buffer is not compressed and deformed. Further, the shape retaining sole 22 is formed with a punched hole 224 for the purpose of appropriately reducing the weight.

  Next, the cushion sole 23 will be described. This is provided on the lower surface of the shape-retaining sole 22 and is prominently deformed by a compressive load. V. A sponge or the like is applied. Of course, the fact that the deformation due to the compressive load is remarkable means that a cushioning effect is exhibited when used as a normal practical footwear. The cushion sole 23 is formed with a stepping guide fulcrum 220 in the shape retaining sole 22 so that a space is formed below the heel support portion 221 or the front support portion 222. It is provided so as to block the part. Therefore, the heel side cushion sole 231 is provided on the lower surface of the heel support portion 221, and the front side cushion sole 232 is provided on the lower surface of the front support portion 222.

  And this heel side cushion sole 231 comprises the spring accommodating part 233 which accommodates the spring 25 for repulsion so that the center part may be hollowed out. The repulsion spring 25 is provided with a metal coil spring as an example, and is provided between the heel portion of the bottom 20 and the heel support portion 221 of the shape retaining sole 22.

  Furthermore, each part of the footwear F which acts at the time of walking etc. in the completion state, or those dimensions are further demonstrated. That is, as shown in FIGS. 1 and 2, first, regarding the height of the sole 2, the sole rear end height dimension in the sole 2 is H, and the toe side sole height dimension from the ground contact surface at the time of standing is H0. The sole rear end height dimension H and the toe side sole height dimension H0 are set to be nearly similar in the stationary state. A point at which the raised portion 201 on the bottom 20 starts is defined as a raised portion starting point P, and a dimension between the shoe tip and the raised portion starting point P is defined as a lifted length dimension L. Further, the dimension of the raised portion at the tip is defined as a raised height dimension G. Further, with respect to the sole 2, focusing on the weight shift during walking, the front and rear direction parts are divided into zones, and the rear end portion is first set as the ground contact start zone Z1, and the range before and after the stepping guide fulcrum 220 is the fulcrum. Zone Z2 is set, and a part closer to the toe is kicked out to be zone Z3. The kick-out zone Z3 is substantially a toe-side range that generally includes the raised portion starting point P.

  The footwear F having the walking promoting effect of the present invention has the configuration as described above, and exhibits the walking promoting effect as follows during walking. First of all, in use, wear it in the same state as normal shoes. When the state at the time of walking is seen, it is grounded from the heel side during normal walking. First, the grounding start zone Z1 is grounded, and the heel side cushion sole 231 and the built-in rebound spring 25 at this part are grounded. Are compressed together (see FIGS. 4A and 4B). After such a state, the vehicle is kicked out or moved in weight instantly. At this time, the ground contact start zone Z1 is set by the action of the repulsion spring 25 incorporated in the heel side cushion sole 231 in the cushion sole 23. While restoring so as to push up the heel, the fulcrum zone Z2 becomes a fulcrum of the swinging movement of the shoe forward and backward, and as shown in FIGS. 4 (c) and 4 (d), it acts as if the shoe behaves like a seesaw. .

  Incidentally, at this time, when the repulsion spring 25 does not exist, the body weight is loaded as it is in the contact start zone Z1 and the fulcrum zone Z2, so that it remains in a lowered state. When walking in this state, it becomes a burden on the muscles of the calf and strengthens the muscles at that site, but it acts like a training shoe. This deviates from the object of the present invention, which is to promote walking during normal practical use. That is, when the body weight is moved to the toe side, the repulsion spring 25 acts as a spring so as to assist the body weight movement to the toe.

  As the weight shifts or the foot is stepped on, the movement is such that the shoes are lowered forward around the fulcrum zone Z2 as shown in FIGS. 4 (e) and 4 (f). Since 20 has a floating part 201 at its front end, as the part, that is, the kick-out zone Z3 contacts the ground, a so-called seesaw-like movement is induced. This movement is a support action that naturally causes the foot to step forward. The lift height dimension G is preferably about 0.5 to 1.0 times, especially 0.7 to 0 when the sole rear end height dimension H on the heel side is used as a reference. More preferable results are obtained when the ratio is about 8 times.

  Further, with respect to the raised portion starting point P, which plays an even more important role for smooth foot depression, when the raised height dimension G is used as a reference, about 1.0 to 2.5 times, particularly 1.8 to It is preferable to make it about 2.2 times, and a more natural walking state can be obtained with such a dimension setting. For the shape retaining sole 22, it is preferable that the stepping guide fulcrum 220, the heel support portion 221, and the front support portion 222 are all integrally formed members. Needless to say, the member may be combined with the center of the shape retaining sole 22. Of course, when further cushioning performance or the like is required between the upper 1 and the sole 2, another buffer material may be interposed.

  Further, in the case of standing work or the like not walking, the footwear F of the present invention does not sink excessively due to the presence of the repulsion spring 25, and a stable use posture of the footwear is maintained.
