Abstract

PROBLEM TO BE SOLVED: To ventilate the inside of shoes not-intermittently but continuously by storing momentary force such as the force of stepping a sole by a heel, the force of back/forth moving of a foot, the variation of pressure given to the sole, or the force of deforming the shoe. SOLUTION: (1) The force of stepping the sole by the heel is transmitted to a blowing means through gears 4 and 5 to rotate a blower 7 to ventilate the inside of the shoe. (2) The force of back/forth moving of the foot is taken out through a weight supported by a spring and the blowing means is operated by the movement of this weight to ventilate the inside of the shoe. (3) Air rooms are provided in front/behind of the sole and through the use of the flow of air generated by the compression of front/behind air rooms by the variation of body weight given to the sole, the blowing means is operated to ventilate the inside of the shoe. (4) The energy of variation of deforming the shoe caused by walking is taken out to operate the blowing means to ventilate the inside of the shoe.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for preventing stuffiness of shoes and boots, and is used for shoes used in workplaces that handle water, such as kitchens and plating factories.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No. 58-153601 discloses a shoe humidity prevention structure in which a fulgo-type air pump is provided at the heel portion of a shoe, and the air pump is pushed down by the heel to send air into the shoe. ing. In this case, the air pump discharges air only at the moment when the heel comes in contact with the ground, and only operates once per step. Therefore, when walking at 120 steps per minute, one foot has 60 steps per minute, that is, 1 step.
It will push the fountain air pump once every second. The time during which the air flows out of the air pump is the time from when the heel starts to push down the figo until it is completely pushed down, and it is instantaneous, and it is considered to be 0.1 second or less. Then, air flows for 0.1 second every other second, and no air flows for 0.9 second. Further, Japanese Patent Application Laid-Open No. 63-31
According to Japanese Patent Application Publication No. 602, a hole for ventilation is formed near the sole on the side of the boot, and at the moment when the heel rises during walking, a portion of the leg sucks out of the hole for ventilation slightly from the tube opening of the boot, A shoe ventilator having a section has been proposed. However, also in this case, the intake and exhaust are performed only intermittently once per step, and the stuffiness cannot be sufficiently prevented.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for obtaining a flow of air necessary for preventing stuffiness by utilizing kinetic energy generated intermittently by walking. And

[0004]

SUMMARY OF THE INVENTION The inventor of the present invention stores a part of the momentary force when the heel steps on the sole of the shoe or when the foot is moving, and then stretches it until the force is applied. I thought that if possible, intermittent force could be changed to continuous force. Then, it was thought that if the blowing means could be operated continuously with the instantaneous force, the air could be constantly sent into the shoe and the effect of preventing stuffiness could be increased.

[0005] When a person walks or runs in shoes or works while standing, his feet move with his toes on the ground, raising his heels, swinging his feet forward, or stopping. The distribution of the pressure applied to the soles of the feet changes as the body sways, even while standing up, down, or standing. Also, when the toes and the instep make a bending motion during walking, the shoes also deform. Utilizing these movements and the force associated with the deformation of the shoes, the energy required to continuously move the blowing means is accumulated in the deformation of metal, rubber, plastic, etc., or the inertia and gas are compressed and accumulated. The energy can be stored in such a way that the battery is charged or converted into electricity, and the blowing means can be continuously operated using the stored energy. By using these methods, it has become possible to move a sufficient amount of air to prevent stuffiness.

That is, according to the first aspect of the present invention, a part of the energy generated by the movement of the foot at the time of walking or the like is stored, and the blowing means is continuously driven by using the stored energy. It is a method of ventilating inside. The invention according to claim 2 is a method for accumulating energy of a change in deformation of a shoe during walking or the like, and continuously driving a blowing means using the accumulated energy to perform ventilation in the shoe. Claim 3 relates to a method for storing energy, a method using mechanical means such as a mainspring, or a method using physical means such as inertia or compression,
Or, it is an invention of a method of converting into electric power by a motor or the like, taking out the electric power, and charging the battery. The invention according to claim 4 is an invention according to one embodiment of claim 1, in which the sole of the foot pushes down the sole of the shoe at every step when a person walks, and the force is accumulated. Since the whole weight is applied to one foot, a large force is applied to the sole and a large amount of energy is obtained. The invention according to claim 5 is an invention according to another embodiment of claim 1, in which an attempt is made to accumulate a force by utilizing the movement when the foot moves so as to swing forward.
The invention of claim 6 is an invention showing another form of the movement in claim 1, and is a method of using energy when there is no movement such as walking. When a person works while standing, the pressure applied to the sole of the shoe due to weight shift varies slightly even when the sole is on the ground. It is intended to capture the change in pressure and accumulate force. By adopting these methods, continuous ventilation is performed as compared with the conventional instantaneous ventilation, thereby increasing the ventilation volume and solving this problem.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It is well known that stuffy feet in shoes are due to insufficient ventilation. Even with a pulp type air pump on the heel of the shoe, the foot gets stuffy if the air volume is small. If the structure is such that the pulp is pressed directly with the foot, the pulp can be pushed only once per step. However, once the force that the foot presses the shoe sole is stored in an elastic body such as a mainspring, and the stored power is used to operate the Figo type air pump, the Figo can be activated many times, and the amount of air blown can be multiplied. You can do it. Now, if you attach a small fan to your shoes and rotate this fan using the force when the heel pushes the sole and the force when the foot moves forward, the fan will not stop immediately due to inertia Therefore, the air is not instantaneous but sent for a while. At this time, if the rotating body is made heavy to increase the coasting force, or if a flywheel that is linked to the rotating body is attached and the force is stored in the flywheel and the fan continues to rotate, the fan will rotate constantly. Can be done. The wind speed at this time depends on the resistance of the air passage,
The air pressure inside the shoe changes because the foot moves forward and backward in the shoe, so the air flow varies, but as in the past,
A remarkably larger air volume can be obtained as compared with a method of intermittent air blowing.

[0008] In addition, when a small fan is attached to a shoe with a structure that turns the fan with a spring, and the spring is rolled up with the momentary force of the heel pressing the shoe sole, the spring starts to rewind when the heel leaves the shoe sole. , Juan turns around and the blast begins. This blowing will continue until the next spring is wound up. The winding of the mainspring may be performed by moving the weight by using the force of moving the foot back and forth. Also, the weight applied to the sole does not always apply to a specific location on the sole, and the location where the weight is applied changes with walking. Even if you don't walk while standing, your body moves or shakes, and the place of weight on the sole moves. The change in pressure applied to the sole of the shoe is captured by two air chambers, and by connecting these air chambers with pipes, the energy of air movement can be extracted. This energy can be used to turn the fan or to wind up the mainspring.

In addition, instead of the above-mentioned mainspring, a small generator can be rotated, the electric power obtained thereby can be charged into a battery, the battery can be discharged, and the generator can be turned to drive the fan. In any case, the wind pressure can be continuously applied to the air passage leading to the inside of the shoe with almost no interruption. As described above, the blowing means is continuously operated by using the instantaneous and intermittently applied force of the foot while storing it. In addition, it is necessary to provide an air passage for taking in outside air and for guiding air discharged from the blower to a stuffy toe portion of a shoe or a sole of a foot.

FIG. 1 shows one embodiment of the present invention. When the push plate (1) is pressed with the heel, the coiled connecting material (2) bent at 90 degrees pushes the plate gear (3), and the plate gear (3) rotates the small gear (4). Let it. Since the small gear (4) and the large gear (5) are integrally formed, the large gear (5) rotates the gear (6) attached to the blower (7) to rotate the blower (7). . Here, the holes for holding the shafts of the large gear (5) and the small gear (4) are made oval so that when the plate gear (3) is pressed, the shaft of the large gear (5) is shifted. When pushed, the gear (6) of the blower (7) meshes and turns the blower, but when the plate gear (3) retreats,
The small gear (4) is disengaged from the gear (6), and the blower (7) can rotate by inertia. Further, instead of the coil-shaped connecting member, hard small balls can be used side by side.

FIG. 2 is a diagram showing another embodiment of the present invention. The weight (1) supported on the sole by the spring (9)
0) is installed, and a gear driving plate (11) is attached to this weight. The plate (11) has a structure that does not work as a gear in the reverse direction. The gear (12) is connected to this plate. A blower may be directly connected to this gear, or the spring may be wound up via a small gear. FIG. 3 shows another embodiment, which utilizes a change in pressure applied to a shoe sole. Air chamber (13) before and after the sole
(14) is provided and this air chamber is connected by two pipes (16) having a check valve (15). The blower (7) is connected to a fan (17) installed in the middle of the pipe. The air chamber is made of elastic material,
The structure is such that exhaust is performed when pressure is applied, and is restored when pressure is no longer applied and air is suctioned. The air chamber (1
3) and (14) are alternately compressed, and air flows through a pipe (16) connecting the air chambers. This air turns the fan (17) installed in the pipe, and drives the blower (7) connected to the fan. In addition, a flywheel (18) is attached to the shaft of the fan so as to store energy and maintain the air flow.

FIG. 4 shows another example of a method of transmitting a force for the heel to press the pressing plate to the blowing means in the present invention. A force cord (19) fixed at one end and supported on the way by a pulley moves by the up and down of the push plate (1). By moving the power cord (19), the blowing means can be operated. Therefore, the position of the blowing means can be attached to the side surface of the boot. Also, by using a pulley, the slight distance that the heel can be pushed down, ie, 1
The length of about 0 mm can be doubled. Furthermore, it can be extended 4 times or 6 times by passing through a number of pulleys. Here, a generator (2
0) is driven to charge the battery (21). Also, the lower rod portion of the push plate (1) is formed into a spiral shape, and a horizontal plate that rotates along with the spiral is attached.
Vertical movement can be changed to horizontal rotation.
FIG. 5 utilizes the deformation of the shoe. An air chamber (22) made of a resilient material is provided in the curved portion of the upper part of the shoe,
A check valve (15) and an air passage (8) are attached to this air chamber. By walking, the air chamber (22) repeatedly operates as an air pump, repeatedly compressing and restoring. In the air passage (8) connected to the air chamber, air flows toward the inside of the shoe due to the check valve (15). A structure for driving the blowing means using the movement of the air will be described.

[0013]

As described above, various movements of the foot are utilized to not only directly move the blowing means, but also to change the force when the foot moves and the weight applied to the foot even when standing. , The force can be accumulated, and the accumulated force can be used to continuously operate the blowing means. Therefore, the amount of air to be blown was increased, and the amount of air required to prevent stuffiness could be obtained, so that stuffiness could be prevented. In addition to the fan, it is easy to ventilate the inside of the shoe by using various blowing means such as a method of entraining and sucking outside air into a jet like an acid egg, in addition to a fan. Also, for the purpose of ventilating inside the shoes,
By using the accumulated force to blow air into the shoe, it is also possible to discharge the moist air in the shoe.

When air is blown or exhausted in the shoes,
Depending on the amount of accumulated power, it is expected that the air will continue to blow even after the shoes are taken off. The upper force on the shoe is a large force considering that one foot supports the whole weight, but the energy required to move the blowing means is smaller than that, so even the force is enough If it can be stored in the shoe, it will be possible to dry the inside of the shoe by blowing and exhausting air for a long time even after taking off the shoes. In any case, the idea of accumulating and using instantaneous but repetitive kinetic energy, such as changes in pressure applied to the sole of a shoe due to foot movement or weight shift, has increased The effect of the present invention is great because the air can be moved twice or several tens times and the effect of preventing stuffiness can be sufficiently improved.
