DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground tabi which is preferably used in civil engineering construction work, agricultural work and the like.

[0002]

2. Description of the Related Art In the past, basement socks have been widely used as work shoes for construction sites and agricultural work, or as leisure footwear for hill climbing and festivals. Underground socks are footwear that has a good sense of scissors and soles of the toes and is similar to barefoot feeling. Therefore, a conventional baseball tabi will be described with reference to FIG. This basement tabi is constructed by integrally connecting an upper 1 composed of a leg tube portion 11 and a shell portion 12 and a rubber grounding bottom 2. An opening portion 13 for putting on and taking off a basement tabi is provided in the leg tube portion 11 by being vertically divided. In the opening 13, a large number of goby 14 and thread 15 are arranged vertically.
The opening 13 is closed by inserting the goby 14 into the thread 15. In addition, since the thread 15 is provided in a plurality of rows for one kohaze 14, the adhesiveness (fitness) can be appropriately adjusted. Also,
The grounding sole 2 has a flat upper surface (substantially parallel) with respect to the grounding surface in order to give a sole feeling close to bare feet.

[0003]

By the way, as described above, in the conventional socks, a flat grounding sole 2 is employed because a barefoot-like comfort is required, so that this is used. When the center of gravity of the person stands naturally, the person is on the rear side (heel side), and there is a difficulty in walking out. In addition, there is a problem that fatigue tends to occur because a slightly unnatural standing posture is maintained for a long period of time, and there is a fear that long-term use may cause lower back pain or cause damage to the heel.

[0004] The present invention has been made in view of the above circumstances, while leaving the barefoot sensation peculiar to the underground tabi as much as possible, preventing the center of gravity from being on the rear side, making it easy to start walking, etc. It aims to provide underground socks that can withstand use.

[0005]

The present invention employs the following means in order to solve the above-mentioned problems. The underground tabi according to claim 1, wherein the tread and the heel on the top surface of the ground bottom are substantially horizontal with respect to the ground surface, in the underground tabi formed by connecting the ground sole to the upper formed by the leg tube portion and the upper part. It is characterized in that an inclined surface is formed on the heel portion of the ground contact bottom, which rises from near the center of the arch to the heel side.

[0006] According to such an underground tabi, an inclined surface is formed which rises from the vicinity of the center of the arch to the heel side so that the heel side becomes higher, so that the center of gravity when standing naturally is higher than the conventional position. Since it moves to the front side (toe side), the burden on the user is reduced, such as easy walking, and fatigue is reduced. In addition, it is preferable that the height of the slope is about 5 ± 1 mm at the highest heel position in a general foot size (in use state) and about 11 cm in length. With the inclination, not only the barefoot feeling peculiar to the underground tabi can be left on the toe side, but also the user can naturally move the center of gravity without feeling the inclination.

[0007] In this case, it is preferable that the inclined surface is formed of an elastic cushion material, so that the foot portion on the toe side has a barefoot sensation peculiar to a basement tabi and exists over a wide range on the heel side. The elastic cushion can absorb the impact on the heel during walking or the like, thereby reducing the burden on the sole. And in the above-mentioned basement tabi, a vertical wall part which stands up from an end is provided in a heel part of the ground contact, and the vertical wall part becomes higher according to the slope and forms a display part in a heel rear part. Preferably, the vertical wall portion can be used for positioning the elastic cushioning material and preventing displacement. In addition, by forming the display part, not only can you easily display trademarks and company names, etc., it also increases the holdability of the heel, one of the most painful parts is reinforced, and in terms of comfort and durability It will be advantageous.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a baseball tabi according to the present invention will be described with reference to the drawings. 1 and 2, reference numeral 1 is an upper, 2A is a ground contact bottom, 11 is a leg tube, 12 is a shell, 13 is a split part, 14 is a kohaze, 15
Is a hanging thread, 20 is a rubber bottom, 30 is an elastic cushion material,
40 is an insole material.

A rubber bottom portion 20 formed of rubber is provided with a design effective for preventing slippage on a lower surface serving as a ground contact surface 21, and an upper surface (rear surface of the foot) 22 has the same shape as when standing on the ground with bare feet. The tread portion and the heel portion have the same or almost the same height from the ground contact surface so as to give the feeling of the sole to the sole, and as a whole, an almost horizontal surface is formed except for the arch. In addition, the rubber bottom portion 20 can be moved from the front toe 23 to the rear heel 24.
Up to this point, the shape has a substantially flat surface (horizontal surface and horizontal surface), but the arch 25 having a curved surface is provided to approximate the actual sole shape. In order to maintain the curved shape of the arch 25, a rubber bottom cloth 26 is integrally attached to the upper surface 22 when the rubber bottom 20 is formed. It is sufficient if it is provided in.

A rubber vertical wall 27 is provided on the heel portion of the rubber bottom portion 20 so as to rise from the peripheral end. The vertical wall portion 27 is raised on the heel 24 side in accordance with an inclined surface of a heel portion described later, and further, the vertical wall portion 27 connected to the rear portion of the heel 24 is formed of a rubber display which is significantly higher than the inclined surface. A part 28 is formed. When the rubber bottom portion 20 is molded, an appropriate trademark, company name, or the like can be simultaneously molded and displayed on the display portion 28.

On the heel portion of the rubber sole 20, an elastic cushion member 30 having an inclined surface S which rises from the toe 23 to the heel 24 is provided. The elastic cushioning material 30 is installed on the upper surface of the heel of the rubber sole 20, and further thereon,
The insole material 40 is installed in an overlapping manner. The insole material 40 is made of a cloth such as a cotton cloth which is installed so as to cover the upper surface 22 of the rubber bottom 20, and has a function of improving comfort when attached to the upper surface of the rubber bottom 20. The elastic cushion member 30 is a plate-like member formed of a material such as foamed rubber, for example, and a desired cushioning property can be provided by appropriately adjusting the elasticity. Therefore, when the weight of the user acts on the elastic cushion member 30, the necessary inclined surface S can be substantially maintained at the same time while exhibiting appropriate cushioning properties.

Here, when the thickness (height) of the inclined surface S formed by the elastic cushion material 30 is set to a general foot size of about 25 to 26 cm, the heel 24 side in a use state where a heavy weight is used. The thickest part is preferably about 5 ± 1 mm, and is set so that a gentle slope S is formed by gradually decreasing the thickness from the maximum thickness to the vicinity of the center of the arch 25 toward the toe 23 side. In this case, the length of the inclined surface S is also 25 to 26 cm.
Assuming a general foot size of the order, it is about 11 cm from the heel 24 to the vicinity of the center of the arch 25 (near the center of the curvature of the arch 25) toward the toe 23, and if the slope S is such a slope, There is no uncomfortable feeling that the elastic cushion material 30 is installed on the sole.

An elastic cushioning material 30 and an insole material 40 are superposed on and integrated with the rubber bottom portion 20 to form the grounding sole 2A of the basement tabi. At this time, since the vertical wall portion 27 is provided, the elastic cushion material 30 and the insole material 4 are provided.
0 is easy to position, and is also effective in preventing displacement after being integrated.

[0014] By combining and integrating the upper 1 with the grounding bottom 2A configured as described above, the manufacture of the basement tabi is completed. Since the configuration of the upper 1 is basically the same as that described in the related art, a detailed description thereof will be omitted here.

Hereinafter, the operation of the above-constructed basement tabi will be described. In this basement tabi, an elastic cushion material 30 is installed on the rubber bottom portion 20 so that the heel 24 side is raised, and an inclined surface S is formed which rises from near the center of the arch 25 on the toe 23 side to the heel 24 side. For this reason, the center of gravity of the user wearing this shifts to the front (toe) side in the state of standing naturally. Such an action can be obtained similarly with an inclined surface formed of a hard member, but since an impact acts on the heel 24 of the sole during walking or the like, an elastic cushion material having cushioning properties is obtained. 30
It is more desirable to use a shock absorber to absorb the impact during walking or the like due to its cushioning property.

As described above, if the center of gravity is moved forward with the baseball tabi on, the walking becomes easier, and the standing posture can be relaxed. Further, the forward movement of the center of gravity not only makes it easy to start walking, but also can prevent lower back pain or heel damage due to long-term use. That is, by moving the center of gravity in the naturally standing state to the toe side more than before, it is possible to stand in an extremely natural posture without applying a load on the waist and heels, thereby improving comfort.

Further, when the elastic cushion member 30 receives a weight or impact, it maintains the inclined surface S without being substantially deformed, and also functions as a cushion member for absorbing the impact during walking or the like. Even after a period of use, a favorable inclined surface S and cushioning properties can be maintained. Therefore,
The elastic cushion 30 exhibits two functions, as well as a high-product-value underground tabi that achieves both durability and comfort, and is advantageous in terms of cost by minimizing the number of parts. In addition, since the elastic cushioning material 30 does not exist around the stepping part on the toe 23 side, a barefoot feeling peculiar to a basement tabi is obtained as before.

Further, since the vertical wall portion 27 and the display portion 28 connected to the vertical wall portion 27 are provided, positioning of the cushioning material and the like is facilitated, and a trademark and a company name can be displayed. Becomes The heel part, which is one of the most painful parts, is a rubber display unit 2.
Since the heel 24 is reinforced, the holdability of the heel 24 is improved, which is advantageous in terms of comfort and durability.

In the embodiment described above, the upper 1 is attached to and detached from the upper 1 by using the goby 14 and the thread 15. However, the present invention is not limited to this. For example, as shown in FIG. It is needless to say that the present invention can also be applied to an underground tabi combined with the upper 1A having another detachable structure using the fastener 16 or the like.

[0020]

According to the above-mentioned underground tabi of the present invention, the heel portion of the ground contact is provided with an inclined surface which rises from the vicinity of the center of the arch to the heel side, so that the center of gravity when worn is more forward than before. It is easy to move and walk, making it less tiring.
In addition, since the cushioning property is obtained on the heel side of the grounding sole, it is possible to absorb an impact during walking or the like.
Therefore, on the toe side, the conventional barefoot sensation is left as it is, centering around the stepping part, and on the heel side, it is hard to be tired, it is easy to stand upright, and it has become possible to absorb shock. By the synergistic effect, the burden on the user's waist and heel can be reduced and the comfort can be improved.

By using the elastic cushioning material, the formation of the inclined surface S and the provision of the cushioning property can be achieved by one component, which has a great effect on reducing the number of components and the cost. Further, since the elastic cushion member can be easily positioned by the vertical wall portion, workability at the time of manufacturing is improved. In addition, even after manufacturing, the presence of the vertical wall prevents the displacement of the elastic cushioning material, and the presence of the display improves the holdability while reinforcing the heel, so that both durability and comfort can be achieved. And provide highly productive underground socks. In addition, since an appropriate trademark or the like can be integrally formed on the display unit, it is also effective in improving the commercial value in terms of design.
