Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to shoes suitable for ice skating, skiing, and other sports.

2. Description of the Related Art Shoes are already known in which a shoe-like base is made of a relatively flexible material, such as leather or synthetic leather, and the outside of this shoe-like base is covered with an exterior body made of synthetic resin.

In particular, for shoes used for ice skating, skiing, and other sports, we use leather, etc. to reduce the cost of shoes and improve durability, abrasion resistance, airtightness, heat retention, stability, etc. Shoes are commercially available that have a shoe-like base made of a flexible material and a multilayered body made of synthetic resin on the outside. However, in the above-mentioned shoes, the outer side of the shoe-shaped base is covered with a synthetic resin exterior body, so the durability and
Although they are excellent in abrasion resistance, waterproofness, heat retention, stability, and foot protection, they have drawbacks such as poor breathability, making feet stuffy and producing a bad odor.

Therefore, a shoe that has a ventilation member with ventilation holes integrated into the sole of the shoe has already been proposed, but when the shoe is in use, dirt and the like can adhere to the ventilation hole and cause clogging. This has the disadvantage that the air permeability effect may be lost.

This invention was made in view of the above circumstances, and aims to provide excellent durability, abrasion resistance, heat retention, waterproofness, stability, foot protection, and breathability.
It is an object of the present invention to provide shoes that can be easily removed even if the ventilation holes of a ventilation panel constituting a ventilation member become clogged with dirt or the like.

That is, the present invention provides a ventilation member having ventilation holes in the sole portion of an exterior body made of synthetic resin that is integrally formed on the outside of a shoe-shaped base, and connects this ventilation member to a frame body and the frame. It consists of a ventilation panel that is removable from the body, and a ventilation hole is provided in this ventilation panel, and if this ventilation hole becomes clogged with dirt, etc., the ventilation panel can be removed from the frame and the debris removed. That's what I did.

The present invention will be described below based on an embodiment shown in the drawings.

1 to 3 show skates used for ice skating, and 1 is a shoe. This shoe 1 consists of a shoe-shaped base 2 made of a relatively flexible material and having breathability, an exterior body 3 made of synthetic resin provided to cover the outside of this shoe-like base 2, and A ventilation member 4 provided at an appropriate location on the sole portion of the shoe; and a porous synthetic resin layer 5 provided at least in a portion corresponding to the ventilation member 4 between the shoe-shaped base 2 and the exterior body 3. It consists of An edge portion 6 is provided on the sole of the exterior body 3. In addition, 7 is a shoelace stopper. The shoe-shaped base 2 is shoe-shaped and is made of a relatively flexible material.
For example, it is made of leather, synthetic leather, or fiber.

Further, it is desirable that the shoe-shaped base 2 has air permeability, and if the shoe-shaped base 2 is made of a non-breathable material, a large number of holes are formed on the bottom 8 of the shoe-shaped base 2 as shown in FIG. Pore 9...
... is provided to provide breathability. Further, the exterior body 3 has a shoe-like shape as a whole and is formed integrally with the shoe-like base body 2, but in the case of shoes, especially sports shoes, a part of the exterior body 3 is shoe-shaped in relation to its function. For example, it is desirable for the torso or the so-called moon-shaped part to have a certain degree of rigidity, and it is desirable for other parts, for example, the outer part of the sole, to have a certain degree of flexibility. Form it so that it looks like this. Furthermore, the exterior body 3 does not need to be formed uniformly on the outer circumferential surface of the shoe-shaped base 2; for example, the exterior body 3 is formed so that a gap is created between the shoe-shaped base 2 and the exterior body 3 in the sole portion of the shoe. A recess may be provided inside.
Ventilation member 4 provided in the sole portion 10 of the exterior body 3
As shown in FIGS. 4 to 6, it is composed of a frame 11 and a ventilation panel 12.

The frame 11 is formed into a ring shape from an elastic material such as rubber, synthetic rubber, or other synthetic resin. This frame body 11 has a tapered outer circumferential surface,
The inner sole side of the shoe 1 has a larger diameter, and the outer sole side has a smaller diameter, and a stepped portion 13 consisting of a collar is integrally provided on the inner peripheral surface of the smaller diameter side, that is, on the outer sole side. For example, four cut grooves 1 are formed in this stepped portion 13 at appropriate intervals.

... are locked to the stepped portion 13 of the frame 11. Therefore, when removing the ventilation panel 12 from the frame 11, rotate the ventilation panel 12 by a predetermined angle, position the protrusions 19 in the cut grooves 14, and remove the ventilation panel 12 from the frame 11. The vent panel 12 is configured so that it can be easily attached to and detached from the frame body 11 by simply pulling it out to the bottom side. The ventilation member 4 configured as described above is attached to an appropriate location in the sole portion 10 of the exterior body 3.

If a recess is provided inside the sole portion of the exterior body 3, the ventilation member 4 should be attached to the side of the sole portion 10 of the exterior body 3 so that its end reaches the recess. You can also do it. Furthermore, between the shoe-shaped base 2 and the exterior body 3, at least a portion corresponding to each ventilation hole 18 provided in the ventilation panel 12 of the ventilation member 4 is porous. A synthetic resin layer 5 is provided.

This porous synthetic resin layer 5 has both breathability and waterproofness, and such a porous synthetic resin layer 5 has, for example,
A porous synthetic resin made of a tetrafluoroethylene polymer, particularly a polytetrafluoroethylene or a fluorocarbon polymer, may be processed into a film and formed by adhesion or other methods on the outer surface of the shoe-shaped substrate 2, or the above resin may be formed into a film by adhering or using other methods. The shoe-shaped substrate 2 can be laminated, or synthetic resin fibers can be compressed under high pressure to form a porous resin sheet, and this can be provided on the outer surface of the shoe-shaped substrate 2 by bonding or other methods. Many waterproof and breathable porous synthetic resin products formed into films or sheets are already commercially available, and these commercially available products can also be used. Next, an example of manufacturing the shoe 1 configured as described above will be described.

First, a shoe-shaped base 2 is made of leather.

In this case, the bottom of the shoe-shaped base 2 is made of relatively hard leather,
The body is made of soft leather. At this time, if the shoe-like base 2 is made of a non-breathable material, the bottom part 8 has many pores 9.
Set up... Then, a porous synthetic resin layer 5 is formed at an appropriate location on the outer surface of the sole of the shoe-shaped base 2 by a method such as lamination or adhesion. Next, an exterior body 3 made of synthetic resin is primarily molded on the outer surface of the shoe-shaped base body 2 by, for example, injection molding. At this time, the mounting holes 21 and 2 of the ventilation member 4 are provided at appropriate locations on the sole of the exterior body 3.
1 is formed, and the porous synthetic resin layer 5 is exposed. Then, the frame 11 of the ventilation member 4 is fitted into the mounting holes 21, 21, for example, via an adhesive. At this time, since the exterior body 3 is only primarily formed, it is thinner than the frame body 11, and the upper half of the frame body 11 is almost buried, and the lower half protrudes from the sole of the shoe. In this state,
When the synthetic resin is secondarily additionally molded by injection molding so that the exterior body 3 has approximately the same wall thickness as the frame body 11, the frame body 11 is integrally fixed to the exterior body 3. In this case, the frame 11 has a tapered outer peripheral surface, a large diameter on the inner bottom side, and a small diameter on the outer bottom side, so that the synthetic resin that is the material of the exterior body 3 changes over time, causing the frame 11 to Even if a slight gap is created between the frame body 11 and the exterior body 3, the frame body 11 will not fall off from the exterior body 3. The ventilation member 4 is completed by inserting the ventilation panel 12 into the frame 11 fixed to the exterior body 3 from the outer bottom side according to the above-described attachment method.

Since the ventilation plate 12 of this ventilation member 4 faces the porous synthetic resin layer 5, the crests 15, grooves 16, and notches 17 formed on the plate surface of the ventilation plate 12・
A ventilation path is formed by...
Further, the structure of the ventilation member 4 is not limited to the above embodiment, but may be constructed as shown in FIGS. 7 to 9.

That is, 22 is a ring-shaped frame body, and 23 is a disc-shaped ventilation plate. The outer peripheral surface of the frame 22 is formed into a tapered surface, and the inner bottom side is formed to have a large diameter and the outer bottom side is formed to have a small diameter. Further, the inner circumferential surface of the frame 22 on the large diameter side is formed as a large diameter portion 22a, and a stepped portion 24 is provided between the large diameter portion 22a and the small diameter portion 22b. On the other hand, on the outer circumferential surface of the inner bottom side of the ventilation panel 23, for example, four locking portions 25 are protruded at appropriate intervals. These locking portions 25 are formed of substantially triangular pyramid-shaped protrusions, and have an inclined surface 26 that slopes downward toward the inner bottom side. And the locking part 25 of the ventilation panel 23...
. . , and position it on the small diameter portion 22b of the frame 22 with the side facing forward, and press fit the ventilation disc 23 into the frame 22 using the elastic force of the frame 22 and the ventilation disc 23. At this time, the locking portion 25
... is elastically contracted and is provided with an inclined surface 26 having a downward slope in the inner bottom side, that is, in the insertion direction,
It can be easily inserted without getting caught, and when the ventilation panel 23 is inserted to the specified position, the locking part 25 ...... will be inserted into the small diameter part 22
b and returns to its original state when it is located at the large diameter portion 22a. Therefore, when the ventilation panel 23 is inserted to a predetermined position in the frame body 22, the locking portions 25 are restored and locked with the stepped portion 24, and cannot be removed. Further, the ventilation board 23 is provided with a large number of ventilation holes 27, similar to the above-described embodiment, and the board surface has peaks 28, grooves 29, etc. . . . and a notch 30 . can. As a result, the ventilation panel 23 can be easily attached to and detached from the frame body 22. Note that the structure for attaching the ventilation member 4 to the exterior body 3 in this embodiment is the same as that in the above-mentioned embodiment, so a description thereof will be omitted.

As explained above, the shoe of this invention has a synthetic resin exterior body integrally formed on the outside of the shoe-like base body, so it has excellent durability and
In addition to being excellent in abrasion resistance, heat retention, stability, and foot protection, the sole of the exterior body is equipped with a ventilation member that has ventilation holes that ventilate the inside and outside, so your feet won't get stuffy. It does not produce any bad odor and can be used comfortably.

Moreover, since the ventilation member is composed of a frame body that is integrally fixed to the exterior body, and a ventilation panel and a vent that are removably attached to the frame body, there is no possibility that dust or the like will adhere to the ventilation holes of the ventilation panel. In the event of clogging, the vent hole can be removed by removing only the vent panel to remove dust and the like inside the vent hole.
Note that the present invention is applicable not only to skate shoes but also to a wide range of sports shoes such as ski boots and mountain climbing shoes.
