Japanese Patent No. 6232652

In the ventilation shoes of Patent Document 1, since the sole is formed by laminating and adhering a plurality of bottom plates, the laminated surface may be peeled off when the ventilation shoes are used for a long period of time, and there remains a problem in strength and durability. .. In particular, in the vicinity of the pump chamber, since compression and restoration are constantly repeated, there is a relatively high possibility that the laminated surface will peel off, which causes problems such as blockage of the exhaust passage and deterioration of the pump function. In addition, laminated lines remain on the exterior, and improvement in design is required.

Therefore, an object of the present invention is to provide a ventilation shoe having high strength, durability and design.

The present invention includes an upper, a board that forms a shoe internal region together with the upper and serves as a bottom plate, a sole that is arranged below the board and the upper, and a ventilation device that ventilates the air inside the shoe. The ventilation device is arranged so as to communicate with the intake passage, an exhaust passage for discharging air into the shoe, a check valve for intake which is arranged in communication with the intake passage, and an intake passage which communicates with the exhaust passage. A check valve for exhaust, a check valve for intake, and a check valve for exhaust are communicated with each other, and a pump chamber provided in the sole is provided. The sole is provided with an insole plate and the insole plate. A check valve for exhaust is mounted on the insole plate including a main bottom plate having a groove-shaped insole plate mounting hole on the upper surface into which the insole plate is fitted, and the pump chamber is a region in front of the footstep portion. The ventilation shoe is formed as a flat chamber by a groove-shaped opening formed on the lower surface of the insole plate and the upper surface of the outsole plate arranged below the insole plate.

As a result, since the entire insole plate is housed inside the surface of the outsole plate, the adhesive surface between the insole plate and the outsole plate cannot be seen from the outside, and the design is improved. In addition, the adhesive surface between the insole plate and the outsole plate is hard to peel off, and the strength and durability are increased.

There is a folded portion on the outer periphery of the bottom of the upper, the board is joined to the upper surface of the folded portion, the lower surface of the folded portion is adhered to the sole, and at least a part of the exhaust passage is the lower surface of the board. It is preferable that the lower surface of the folded portion is joined to both the surface peripheral edge portion of the insole plate and the surface peripheral edge portion of the outsole plate.

According to this, since the folded portion of the upper is adhered to the upper peripheral peripheral portions of both the insole plate and the outsole plate, the insole plate and the outsole plate are firmly fixed, and the durability is further improved. In particular, since the area around the pump chamber is repeatedly compressed and restored, it is fixed not only by the adhesion between the insole plate and the outsole plate but also by the upper, so the possibility of peeling is low, which causes the exhaust passage to be blocked and the pump function to deteriorate. It can be suppressed. Here, the folded-back portion may be adhered to the upper surface peripheral portions of both the insole plate and the outsole plate over the entire circumference, or a part of the folded-back portion is adhered to the upper surface peripheral portions of both the insole plate and the outsole plate, and the like. May be adhered only to the upper peripheral edge of the outsole plate.

In a state where the insole plate is fitted into the insole plate mounting hole, it is preferable that the surface peripheral portion of the insole plate is flush with the surface peripheral portion of the outsole plate at the connecting portion.

This facilitates adhesion between the insole plate, the upper surface of the outsole plate, and the lower surface of the board.

It is preferable that the outer peripheral surface of the side plate of the insole plate surrounding the opening is adhered to the inner peripheral side surface of the insole plate mounting hole.

According to this, the adhesive area between the insole plate and the outsole plate is increased, the adhesion can be further strengthened, and the sealed state of the pump chamber can be maintained for a long period of time.

The exhaust check valve is provided at the heel position in the insole plate, and at least a part of the exhaust passage is in front of the exhaust check valve and between the upper surface of the insole plate and the lower surface of the board. A plurality of pump chamber cushions are provided in the pump chamber, and the upper surface of the insole plate is provided with a spacer in the exhaust passage that projects in a shape covering a position corresponding to the pump chamber cushion. preferable.

As a result, it is possible to prevent the insole plate from rising due to the action of the pump chamber cushion and the exhaust passage from being blocked by the spacer in the exhaust passage.

The intake check valve is mounted in the insole plate, and at least a part of the exhaust passage is provided in front of the exhaust check valve and between the upper surface of the insole plate and the lower surface of the board. A sealing material is installed between the board and the insole plate, and the sealing material has a hole, and the hole communicates the intake opening provided in the board with the intake check valve. It is preferable to do so.

As a result, the intake passage and the exhaust passage can be easily separated.

It is preferable that the intake check valve is provided at the heel position in the outsole plate, and at least a part of the intake passage is formed in an intake cylinder arranged outside the shoe inner region.

As a result, when applied to boots or the like, communication with the outside air becomes smooth.

The outsole plate is composed of an outsole plate main body and a check valve mounting block for intake air. The check valve mounting block for intake air forms a part of a heel, and is located in a check valve mounting hole for intake air and below the check valve mounting hole. It is preferable to include a horizontal passage.

As a result, the outside air can be sucked from the intake cylinder only by providing the laminated surface between the outsole plate main body and the check valve mounting block for intake only on the inconspicuous heel.

The ventilation shoes according to the present invention have high strength and can suppress deterioration of the ventilation function due to peeling of the laminated surface of the plate forming the sole even after long-term use, and a laminated line appears in appearance. Can be suppressed. Moreover, the manufacturing process can be simplified.

Hereinafter, the first embodiment of the present invention will be described with reference to FIGS. 1 to 14. The ventilation shoe 1 includes an upper 2, a board 3, an insole plate 4, an outsole plate 5, and a ventilation device that ventilates the air inside the shoe. Here, in the present embodiment, the inside of the ventilation shoe 1 is formed by the upper 2, the board 3, and the inlay plate 9 that comes into contact with the back surface of the foot. The inlay plate 9 may be detachably arranged on the board 3 or may be adhered to the upper surface of the board 3. The insole plate 4 and the outsole plate 5 are made of an elastic material such as hard rubber or soft synthetic resin, and the contact surfaces are adhered with an adhesive or the like to form the entire sole 10. On the outer periphery of the bottom of the upper 2, there is a folded-back portion 21 that is folded back toward the inside of the shoe, the lower surface of the board 3 is joined to the upper surface of the folded-back portion, and the lower surface of the folded-back portion 21 is adhered to the upper surface of the sole 10. Will be done.

The inlay plate 9 is a plate in contact with the foot, and as shown in FIG. 4, a plurality of intake holes 91 are formed in the rear of the inlay plate 9, and a plurality of injection holes 92 are formed in the front. When the inlay plate 9 is arranged inside the shoe, the intake hole 91 is arranged on the rear bending surface as shown in FIGS. 1 to 3. The board 3 is arranged on the lower surface of the inlay plate 9, and as shown in FIG. 5, an intake hole 31 is formed in the rear of the board 3 in front of the position corresponding to the intake hole 91 provided in the inlay plate 9. An intake groove 32 is formed on the upper surface behind the intake hole 31 in order to communicate the intake hole 91 and the intake hole 31. A plurality of injection holes 33 are formed in front of the board 3 at a location corresponding to the injection holes 92 and larger than the injection holes 92. The intake hole 91 of the inlay plate 9 can also be opened at a position communicating with the intake hole 31 of the board 3.

Below the board 3, a sole 10 composed of an insole plate 4 and a bottom plate 5 is arranged via a folded-back portion 21 of the upper.

The insole plate 4 is one size smaller than the outsole plate 5 in a plan view, and the outsole plate 5 is equipped with a groove-shaped insole plate having an inner peripheral shape having substantially the same size and shape as the outer peripheral shape of the insole plate 4. It has holes H (see FIGS. 10 and 11). The insole plate 4 is fitted and accommodated in the insole plate mounting hole H. In a state where the insole plate 4 is housed in the outsole plate 5, the surface of the insole plate 4 is flush with the surface of the outsole plate 5 at the connecting portion. That is, the surface peripheral edge portion 410 of the insole plate 4 and the surface peripheral edge portion 54 of the main bottom plate 5 are flush with each other at the connecting portion.

As shown in FIGS. 7 and 9, the lower surface of the insole plate 4 has a wide groove-like shape that extends to include the area in front of the wearer's arch, specifically, the toes and the bases of the toes. An opening 42 is formed, and a narrow groove 49 communicating with the opening 42 is formed behind the opening 42. An intake communication hole 45 and an exhaust communication hole 46 are formed on the lower surface of the heel portion of the insole plate 4 behind the opening 42 and the narrow groove portion 49. Further, as shown in FIG. 7, an intake valve mounting hole 43 and an exhaust valve mounting hole 44 are formed directly above the intake communication hole 45 and the exhaust communication hole 46.

On the lower peripheral edge portion of the insole plate 4, a step portion 41 that falls downward from the outer peripheral edge toward the center is provided on the outside of the opening 42. The step portion 41 corresponds to the position of the step portion 53 of the main bottom plate 5, which will be described later, when the insole plate 4 is accommodated in the insole plate mounting hole H. This makes it easy to determine the range of adhesive application for adhering the insole plate 4 and the outsole plate 5. When the insole plate 4 is housed in the outsole plate 5, the outsole plate 5 is arranged on the lower surface of the insole plate 4, so that the space of the opening 42 becomes the pump chamber P. The opening 42 is formed so as to be surrounded by a side plate 411 projecting downward from the lower surface of the insole plate 4. When the insole plate 4 is accommodated in the insole plate mounting hole H, the outer peripheral surface of the side plate 411 abuts on the inner peripheral side surface of the insole plate mounting hole H and is adhered to the inner peripheral side surface. In the present embodiment, the side plate 411 includes the step portion 41, and the inner peripheral side surface of the insole plate mounting hole H includes the step portion 53.

In the present embodiment, the intake valve mounting hole 43 and the exhaust valve mounting hole 44 are formed on the upper surface side of the insole plate 4, but as a modification, the intake valve mounting hole 43 and the exhaust valve mounting hole 44 are formed. May be formed on the lower surface of the insole plate 4, and the intake communication hole 45 and the exhaust communication hole 46 may be formed directly above them.

As shown in FIGS. 7 to 9, pump chamber cushions 47, 47 extending downward and extending downward are adhered to the inside of the opening 42. The thickness of the pump chamber cushions 47, 47 is preferably the same as or slightly thicker than the depth of the pump chamber. The pump chamber cushions 47, 47 contribute to restoring the compressed pump chamber P and prevent a decrease in ventilation capacity due to deformation of the pump chamber.

The materials of the pump chamber cushions 47 and 47 are not limited as long as they have high elasticity and durability, but rubber, urethane foam and the like are used.

As shown in FIGS. 6 to 8, on the upper surface of the insole plate 4, protruding exhaust passage spacers 48, 48 extending back and forth are integrally formed on the right side and the left side from the center. This is for securing the exhaust passage L2, which will be described later, even when the pump chamber P is compressed by the toes or the like during walking. The thickness of the spacers 48, 48 in the exhaust passage is preferably about the same as or thinner than the thickness of the folded-back portion 21.

As shown in FIG. 8, the spacers 48 and 48 in the exhaust passage preferably have a shape that covers all the positions corresponding to the pump chamber cushions 47 and 47 in a plan view. The spacers 48, 48 in the exhaust passage may have substantially the same position and shape as the pump chamber cushions 47, 47 (shapes in plan view and rear view), include the positions of the pump chamber cushions 47, 47, and more than that. It may have a large shape. The spacers 48, 48 in the exhaust passage play a role of pushing back the pump chamber cushions 47, 47 when the pump chamber cushions 47, 47 are compressed and a force for pushing up the corresponding portion of the insole plate is applied. As a result, even if the ventilation shoes 1 are used for a long period of time, the portion of the insole plate 4 corresponding to the location is raised upward by being repeatedly pushed by the pump chamber cushion 47 during compression, which blocks the exhaust passage L2. It is possible to suppress the deterioration of the pump function.

The bottom plate 5 is a portion in contact with the ground, and a heel is formed on the heel portion. Further, as shown in FIG. 10, a groove-shaped narrow groove portion 51 is formed on the upper surface of the rear portion of the bottom plate 5. The narrow groove portion 51 communicates with the rear end portion of the narrow groove portion 49 of the insole plate 4 at the front end portion of the narrow groove portion 51 when the insole plate 4 is housed in the main bottom plate 5 and communicates with the pump chamber P. Make up a common road. Further, the narrow groove portion 51 crosses below the communication holes 45 and 46 at the rear portion and communicates with each other (see FIG. 13).

As shown in FIGS. 10 and 11, a band 52 is adhered or integrally molded on the outer periphery of the upper surface of the bottom plate 5 in order to improve the design. The band 52 can be appropriately designed to have a concavo-convex shape, a perforated shape, and the like. At the inner peripheral edge of the insole plate mounting hole H of the bottom plate 5, a step 53 that falls downward toward the center is provided at a position corresponding to the step 41 of the insole plate 4. The heel is integrated with the outsole plate 5 by adhesion or integral molding. The cavity in the heel is for reducing the weight and suppressing deformation during molding.

The board 3 is adhered to the upper surface of the folded portion 21 of the upper 2, and the sole 10 is bonded to the lower surface of the folded portion 21 of the upper 2. Therefore, the folded portion 21 forms a gap between the board 3 and the upper surface of the sole 10. It is used as an exhaust passage L2 as described later.

Further, as described above, the insole plate 4 is fitted and adhered to the insole plate mounting hole H of the main bottom plate 5. In a state where the insole plate 4 is housed in the outsole plate 5, the surface peripheral edge 410 of the insole plate 4 becomes the same surface as the surface peripheral edge 54 of the outsole plate 5, and the lower surface of the folded-back portion 21 of the upper 2 is a book on the entire circumference. Since the surface peripheral edge portion 54 of the bottom plate 5 and the surface peripheral edge portion 410 of the insole plate 4 are in contact with each other and adhered to each other, it is useful for firmly fixing the outsole plate 5 and the insole plate 4. Further, the opening 42 forming the pump chamber P is surrounded by the side plate 411 protruding downward from the back surface of the insole plate 4, and the outer peripheral surface of the side plate 411 is adhered to the inner peripheral side surface of the insole plate mounting hole H. , The insole plate 4 and the outsole plate 5 are more firmly joined. As a result, when the ventilation shoes 1 are used for a long period of time, a load is applied around the pump chamber P due to repeated compression and restoration of the pump chamber P, but there is no concern that the insole plate 4 and the outsole plate 5 will come off. Since the folded-back portion 21 of the upper 2 is present so as to avoid the upper surface of the pump chamber P, it does not interfere with the compression of the pump chamber.

As shown in FIGS. 6 and 7, the sealing material 7 fixed between the insole plate 4 and the board 3 includes a hole 71 and a U-shaped notch 72. The hole 71 communicates the intake hole 31 provided in the board 3 with the intake check valve V1, and the notch 72 is the exhaust check valve V2 and the insole plate in the region in front of the exhaust check valve V2. It communicates with the exhaust passage L2, which is the space between the upper surface of the 4 and the lower surface of the board 3. The sealing material 7 has a role of fixing the intake check valve V1 and an exhaust check valve V2 and a role of separating the intake passage L1 and the exhaust passage L2 to prevent the intake air from leaking into the exhaust passage L2. Fulfill. The sealing material 7 is made of sponge rubber or the like, and is preferably about 1 mm thicker than the distance between the insole plate 4 and the board 3.

Next, the structure for ventilation will be described.
The ventilation device includes an intake passage L1 that sucks air from the outside through the inside of the shoe, an exhaust passage L2 that discharges air inside the shoe, a check valve V1 for intake that is arranged in communication with the intake passage L1, and exhaust. It includes an exhaust check valve V2 that communicates with the passage L2, and a pump chamber P that communicates with the intake check valve V1 and the exhaust check valve V2. The pump chamber P is a flat chamber between the insole plate 4 and the outsole plate 5, extends forward from the arch position, and extends to the base of the toes, toes, and toes.

The intake passage L1 is provided in a plurality of intake holes 91 of the inlay plate 9, an intake groove 32 provided in the board 3, an intake hole 31 of the board 3, an inner peripheral surface of the hole 71 of the sealing material 7, and an insole plate 4. It is composed of a communication hole 45 for intake air, and takes in outside air. The exhaust passage L2 is a space between the upper surface of the insole plate 4 and the lower surface of the board 3 in front of the exhaust communication hole 46 provided in the insole plate 4 and the exhaust communication hole 46, and the injection hole 33 of the board 3. The air inside the pump chamber P is injected into the vicinity of the toes inside the upper 2, and the air inside the upper 2 is exhausted to the outside through the gap of the instep portion.

The intake check valve V1 is arranged so as to communicate with the intake passage L1. The exhaust check valve V2 is arranged so as to communicate with the exhaust passage L2. The intake check valve V1 and the exhaust check valve V2 are provided at the heel position on the heel in the insole plate 4. Since it is the most reinforced and less susceptible to deformation in shoes, damage to the check valve is prevented.

Next, the structures of the intake check valve V1 and the exhaust check valve V2 will be described with reference to FIG.
The intake check valve V1 and the exhaust check valve V2 have the same structure, and include a valve body T, an open case 81, and a cover 82 that is fitted into the open case 81 without a gap.
