Description

[0001]
[Industrial application fields]
The present invention relates to a basement used in a civil engineering or construction site.
[0002]
[Prior art]
Each time underground, it consists of a structure where a rubber or synthetic resin grounding bottom is attached to an upper that is generally sewn with cotton cloth, covers the legs from the buttocks of the legs, and can fit the legs with a kohaze, In addition, since it uses a flexible bottom material and has a finger crotch, it has a feature that it has a degree of freedom in movement of the foot, a good grounding feeling, and can be worn lightly.
[0003]
By the way, as mentioned above, the upper fabric is also made of cloth because of the requirement for lightness as described above, so the upper fabric may be worn or damaged when the toe part touches or collides with the object during wearing. Unfortunately, it also affected the toe area.
[0004]
Therefore, the portion where the upper and the ground bottom including toes since ancient times in contact with each underground, i.e. it is being performed to fix by meditating the rubber tape or the like to the ground portion, be secured in this way the rubber tape as a whole There is a concern that it causes an increase in weight and affects the movement of the finger, and it is not advantageous from the viewpoint of air permeability.
Also, it is called winding, and a part of the grounding bottom is extended to the outside and fixed to the upper, but this is suitable for the case where an unvulcanized grounding bottom is attached and is sewn. There was also a concern that it would be difficult to apply each time the basement was applied, and that the appearance would be uncomfortable.
In addition, for the purpose of protecting the toe part from falling objects, a proposal has been made to attach a metal tip to this part, but if the tip to cover the toe part is fixed, the weight of the toe part increases, and There was a risk of breaking the balance. In addition, in this case, the tip of the toe hits the tip of the tip, and the impact received on the tip of the toe cannot always be reduced.
[0005]
[Problems to be solved by the invention]
In view of the above-mentioned situation, the present invention has studied the basement that does not impair the lightness, breathability and balance of the foot, and can be protected from contact and collision of the toe portion, and has reached the present invention. .
[0006]
In the basement where the ground contact bottom is attached to the upper by a sewing method, the outer surface of the tip of the tip of the toe is slightly separate from the lower end of the center of the tip of the thumb and the four fingers so that each has a separate toe shape And the outer surface is satin or uneven , and a hard-shaped shape-retaining piece is interposed at the end of the back of at least approximately the center, and the hanging piece is connected downward. an elastic material made of cushioning strips, in each underground, characterized in that is sewed in contact with the upper.
In addition, the present invention is characterized by using a buffering piece in which a sewing thread storage groove extending along the peripheral edge is formed inside the upper peripheral edge, and the present invention is also characterized by using a shape-retaining piece encapsulated with a flexible material. It is what.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings illustrating the embodiments.
FIG. 1 shows an example of the basement of the present invention. A grounding bottom 2 made of rubber or synthetic resin is attached to an upper 1 made by sewing cotton cloth or the like by sewing or using both sewing and bonding together. It has become. In the figure, reference numeral 3 denotes a cohesive, 4 is a cochase hanging thread, 1A denotes an upper covering cloth, 1B denotes an inner bottom, 1C denotes a covering cloth for a toe part, and 1D denotes a covering cloth for a hook part.
[0008]
The present invention has a curved shape so that each of the outer surfaces of the tip of the toe from the lower end of the tip center of the thumb part and the four finger part is slightly separate from each other and conforms to the toe shape in the basement constructed as described above. Furthermore, the outer surface has a satin finish or an uneven shape, and a hard material shaped retaining piece 6 is interposed at the abutting position of at least approximately the center of the back surface, and a hanging piece 5B is continuously provided below. the cushioning piece 5 made of elastic material is, is characterized in that is sewn in a state of contact with the upper.
[0009]
The shock-absorbing piece 5 used in the present invention has a thumb part and a four-finger part separately, and as shown in FIG. It has a curved shape so that the contact and collision received by the toe portion are alleviated. As the material of the buffer piece 5, a molded product of elastic material such as rubber or synthetic resin can be used. As shown in the illustrated example, the outer surface is satin-finished or an uneven shape is exhibited to exhibit an anti-slip effect. It is also possible to exert a further effect of preventing wear.
[0010]
Then, the buffer piece 5 is brought into contact with the outer surface of the upper 1, and an adhesive is interposed on the inner surface as necessary, and is sewn and fixed using a sewing thread storage groove 5A provided on the upper peripheral edge thereof. Note that connecting pieces 5B hanging below the buffer strip 5 as shown, when sewing the ground base 2 after elaborate hanging it simultaneously hanging of the upper 1, robust and stable attachment Tekatsu The appearance can also be finished neatly.
[0011]
In the embodiment shown in FIG. 2 , since the shape retaining piece 6 made of a hard material is interposed at the abutting position in the center of the back surface of the cushioning piece 5, the curved shape retaining effect of the cushioning piece 5 is further enhanced and the basement is worn frequently. At this time, the fingertip fits better, and moderate cushioning and tension are imparted to the buffer piece 5 corresponding to the part that first collides with another object, thereby further enhancing the buffering effect of the present invention. The shape-retaining piece 6 may be a synthetic resin sheet piece, net piece, FRP molded product, metal sheet piece, net piece, or the like that is molded on a flat plate or in a curved shape. It adheres to the back surface of the buffer piece 5 by wearing.
[0012]
The shape-retaining piece 6 used in the present invention is not limited to the above example but is made larger than this. For example, as shown in FIG. 6, the shape-retaining piece 6 is formed so as to be along substantially the entire back surface excluding the suspended piece 5B. It can also be interposed. If it does in this way, the shape retention effect of the buffer piece 5 can be improved further.
Further, as shown in FIG. 7, a flexible material 7 such as a sponge or a nonwoven fabric can be encapsulated on the entire surface or both surfaces of the shape-retaining piece 6, and the relaxation effect per foot against the toe can be improved.
[0013]
In the basement thus obtained, the toe part of the thumb part and the four finger part can be protected from contact and collision of the container by the buffer piece 5, and also exhibits the effect of resisting friction and wear of this part, The curved three-dimensional shape of this portion is maintained, and it is very easy to put the toe into the footwear when worn, the influence on the toe can be prevented, and the appearance of this portion is improved.
[0014]
【The invention's effect】
Since the present invention is configured as described above in detail, it has the same breathability, grounding feeling and lightness as the basement of a general sewing method , and the toe is protected by the presence of a buffer piece. In addition, the strength of friction and wear of the upper toe portion is improved, and further, a shape retaining piece made of a hard material is interposed on the back surface of the cushioning piece, so that a cushioning effect is imparted with moderate hardness and tension. There is an advantage that the effect can be further enhanced, the weight is not increased and the balance is not lost , and the buffer pieces are firmly and stably attached, and the appearance is beautifully finished to provide a comfortable basement.
