Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a waterproof garment.

[0002]

2. Description of the Related Art Waterproof clothing includes waterproof diving clothing used for diving (hereinafter referred to as dry suit), life jacket, and fishing pants for waterproofing the lower body. The dry suit has a pressure air supply valve that regulates the supply of air from the air tank so that the air supplied from the air tank stays inside and adjusts the internal air pressure according to the diving depth etc. An exhaust valve is provided for exhausting the air that has accumulated in the air. In a conventional dry suit, only an exhaust valve that exhausts internal air when the posture in water is horizontal or the head is located above is attached. The exhaust valve is usually attached to a portion covering the upper arm which is a part of the upper body so as to be easily operated.

[0003]

However, if the exhaust valve is attached only to the portion covering the upper body as in the above-mentioned conventional dry suit, the diver raises his / her foot above the horizontal position at the center of the body. In such a case, the air inside collects in a portion covering the feet. The air is not discharged and generates buoyancy, so that the diver cannot change posture while being upside down. When the foot rises in this way, the surrounding water pressure decreases due to the rise, and the volume of the portion covering the foot increases without being exhausted. Therefore, the buoyancy is further increased with the ascent. In the worst case, the diver floats up to the surface of the water at once, causing an accident such as sickness. In order to prevent this, countermeasures such as diving with a weight of several hundred grams on the ankle have been taken, but no complete solution has been proposed.
In addition, even if you are wearing fishing pants, if you accidentally throw them into the water, the air will accumulate in the part that covers your feet, so your feet will float up and you will not be able to take your face out of the water. There is an accident that can not be done.

Therefore, an object of the present invention is to provide a waterproof garment capable of appropriately discharging the air accumulated therein in a well-balanced manner and keeping the user's posture in the water in a suitable state.

[0005]

In order to solve the above problems, the present invention has the following arrangement. That is, the present invention
In a waterproof garment that prevents water from entering the inside, an exhaust valve that exhausts air accumulated in an internal space in the vicinity is disposed in a portion that covers the distal end side of the leg portion. According to this, since the exhaust valve for exhausting the air accumulated in the internal space in the vicinity is arranged in the portion covering the distal end side of the leg portion, the air accumulated inside can be appropriately discharged in a well-balanced manner. Therefore, it is possible to prevent the legs from being lifted up, and it is possible to appropriately maintain the user's posture in water.

Further, the exhaust valve automatically opens when the inside pressure becomes higher than the outside pressure by a predetermined pressure or more, and the air accumulated inside is exhausted. Since it is an auto valve with a check valve function that prevents water from entering the inside, it is possible to automatically respond even in an emergency, so safety can be improved.

The auto valve is provided with a base portion having an exhaust port for waterproof clothing and a valve seat formed on the periphery of the exhaust port, and is detachably provided on the base part while covering the base portion. , A cover portion having a vent hole capable of ventilating with the outside world and a spring elastically mounted between the cover portion and the valve seat constantly abuts on the valve seat to close the exhaust port, so that the inner pressure of the waterproof garment is the outer pressure. By providing the valve body that automatically opens the exhaust port when the temperature rises, it is possible to preferably discharge the air accumulated in the internal space and prevent water from entering.

Further, the valve body is formed of a material having a high rigidity so as to cover the exhaust port and is larger than the exhaust port, and a ring-shaped member made of a highly elastic material. By comprising the valve holder portion and the ring valve mounted so as to be watertightly sandwiched between the valve seat, it is possible to reliably prevent water from entering the inside of the diving equipment.

The present invention also provides the waterproof garment, wherein the waterproof garment is a dry suit in which another exhaust valve is arranged in a portion covering the upper body.

Further, since the other exhaust valve is the above-mentioned auto valve, exhaust can be completely automated. Further, since the other exhaust valve is an auto valve with a manual function having a function of being able to open and close manually, the safety of the waterproof clothing can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory view showing one embodiment of a dry suit according to the present invention. 10
Is a dry suit, which is waterproof clothing that covers the whole body and prevents water from entering the inside. An air supply valve 14 is an air supply valve for introducing air from an air tank (not shown) into the dry suit 10. Reference numeral 16 denotes a main exhaust valve, which is an exhaust valve for exhausting air staying in the dry suit 10.

Numeral 12 is an auto valve, which is arranged in a portion covering the front ends of both legs and acts as an exhaust valve for exhausting the air accumulated in the internal space in the vicinity thereof. The auto valve 12 is preferably provided at the tip of the foot portion of the dry suit 10 as much as possible, but is actually installed at a place where it does not interfere with fins, for example, both ankles. If it is installed at least at the tip of the knee, air in the internal space formed at the portion covering the leg can be effectively discharged. Thereby, it is possible to prevent the legs from being lifted up, and it is possible to appropriately maintain the user's posture in water. That is, even if the internal air moves to the foot due to a change in posture during diving, the internal air is exhausted by the exhaust valve (in this example, the auto valve) attached to the tip portions of the both feet (the ankle portion in the example). ), It is possible to maintain the user's posture in water appropriately.

The auto valve 12 is automatically opened when the inside pressure becomes higher than the outside pressure by a predetermined pressure or more, and the air accumulated inside is discharged, so that the outside pressure becomes higher than the inside pressure. It has a check valve function to prevent water from entering inside. This makes it possible to respond appropriately even in an emergency,
The safety can be improved.

A specific structure of the auto valve 12 will be described below with reference to FIGS. 2 and 3. Reference numeral 20 denotes a base portion, which is fixed to a circular opening formed through a donut-shaped rubber sheet 24 attached to a cloth 22 of a diving tool (dry suit), and forms an exhaust port 26 of the dry suit. I do. The base portion 20 has a valve seat 28 formed on the periphery of the exhaust port 26. In this embodiment, the male screw portion for mounting the base portion 20 is screwed into the female screw portion of the back cap 30 inside the rubber sheet 24, and the rubber sheet 24 is sandwiched between the base portion 20 and the back cap 30. Thereby, the base part 20 is fixed to the opening of the rubber sheet 24. Further, the base portion 20 and the back cap 30 are fixed to the rubber sheet 24 in a watertight state by concentric ridges (not shown) formed on the surface in contact with the cloth. Reference numeral 30a denotes a plate portion formed as a part of the back cap 30 so as not to block the exhaust port 26.

A cover portion 32 covers the base portion 20 and is detachably screwed to the base portion 20. The cover portion 32 has a ventilation port 33 that allows ventilation with the outside world. Numeral 36 denotes a valve body, and a spring 3 mounted between the upper surface of the valve body 36 and the upper inner surface of the cover 32.
4 always contacts the valve seat 28 to close the exhaust port 26, and when the internal pressure of the dry suit 10 rises above the external pressure, the dry suit 1 is resisted against the urging force of the spring 34.
The air outlet 26 is automatically opened by moving outward (upward in the drawing). Thereby, it is possible to preferably discharge the air accumulated in the internal space and to prevent water from entering.

The valve body 36 is made of a material having a high rigidity and a valve holder portion 37 made of a material having a high rigidity.
A ring valve 38 is mounted on the outer periphery of the valve holder 37 so that the peripheral edge is exposed in a ring shape. Ring valve 3
Numeral 8 is attached by being inserted into a circumferential groove formed on a lower surface formed on the valve holder portion 37 on the inner diameter side. Since the external pressure acts on both the valve holder portion 37 and the ring valve 38, unlike the valve body entirely formed of an elastic material, the deformation due to the external pressure can be suppressed to a small extent, and water can enter the dry suit 10 inside. It can be reliably prevented. The lower part 37b of the valve holder part 37
Is in sliding contact with the inner wall of the exhaust port 26 formed by the base portion 20. Thus, the valve body 36 is guided so as to be able to move in the vertical direction.

The auto valve 12 includes a valve body 36 and a spring 34 for pressing the valve body 36.
The amount of air stored inside is determined by the pressing pressure of, and acts as an automatic regulating valve. The spring 34 is not limited to the coil spring as in the present embodiment, but may be any elastic member that acts as a spring, and a leaf spring or the like may be used. The spring pressure can be set freely according to the operating conditions.
Normally, the air is exhausted so that the user does not invert in the water, and the check valve function can be effectively operated.
It may be set to about 30 cm of water column.

The spring pressure of the spring 34 may be variable. Adjusting the spring pressure is effective in optimizing the buoyancy of the foot due to differences in buoyancy due to differences in physique and the like. Further, a lock function for intentionally stopping the function of the valve may be provided. In the present embodiment, the exhaust valve (having only the automatic function) configured so that the valve element 36 is automatically opened at a predetermined differential pressure is attached. However, the main exhaust valve that can be manually operated is provided. 16 may be used.

Further, the above-mentioned auto valve 12 has a simple structure and can be easily disassembled and cleaned. By removing the cover 32, the valve body 36 and the spring 34 can be removed. Since the disassembly is easy and the number of parts is small, cleaning for removing attached salts and the like can be easily performed. Thereby, it is possible to prevent a problem such as intrusion of water into the suit.

Next, the operating state of the auto valve 12 of the above embodiment will be described. When the internal pressure of the dry suit 10 becomes higher than the external pressure, the auto valve 12 moves the valve body 36 in a direction to open the exhaust port 26 against the urging force of the spring 34, and the differential pressure becomes higher than a predetermined value. , The air in the dry suit 10 can be exhausted by opening the exhaust port 26. Air flows into a groove 37a provided in the valve holder 37.
And passes between the ring valve 38 and the surface of the valve seat 28, and is discharged from the vent 33.

When the inner pressure of the dry suit 10 is smaller than the outer pressure, the outer pressure is applied to the entire surface of the valve body 36, so that the ring valve 38 is closed by the ring valve 38 so that the valve body 36 closes the exhaust port 26. It is strongly pressed against the surface of 28. That is, the pressure acting on the entire surface of the valve body 36 acts on the circumferential line where the ring valve 38 and the surface of the valve seat 28 are in contact, so that watertightness can be ensured. In addition, the valve holder 37 is connected to the exhaust port 26.
The ring valve 38 is sandwiched between the outer peripheral portion 37c of the valve holder 37 and the valve seat 28, so that watertightness is ensured. And the valve holder part 37
Is supported by the valve seat 28 through the ring valve 38 all around the outer peripheral portion 37c, so that the valve body 36 as a whole has a structure resistant to external pressure. That is, the valve element 36
Can be prevented from being turned up by external pressure. As shown in FIG. 2, the cross-sectional shape of the ring valve 38 is thin at the tip end side and is formed of a material having high flexibility.
The moving length of the valve element 36 is restricted by 2. Therefore, when an external pressure is applied, the ring valve 38 can be suitably deformed in the water-tight direction and can abut on the surface of the valve seat 28, so that the water-tightness can be ensured. That is, since the peripheral portion 38a of the ring valve 38 is formed in a lip shape, the valve body 36 can react sensitively to a pressure difference, and can suitably exhibit a function as a check valve.

Further, in the dry suit described above, the auto exhaust valve 12 shown in FIG. 2 may be used as the main exhaust valve 16 disposed in the portion covering the upper body (the upper arm in the embodiment). . That is, the auto-valve 1 is provided at all positions including the portion covering the tip of the leg portion (two portions in this embodiment) and the portion covering the upper body (one portion in this embodiment).
2 may be used. Thereby, the exhaust of the dry suit can be completely automated, and the cost can be reduced as compared with the case where an automatic valve with a manual function is used because the automatic valve 12 has a simple structure. Regarding safety, since the automatic valves 12 are provided at a plurality of locations, a plurality of functions are not impaired at the same time. Therefore, even if each exhaust valve does not have a manual function, the safety can be substantially improved as compared with the case where one exhaust valve is provided. In the case of a dry suit, if an auto valve with a manual function having a function that can be manually opened and closed as in the past is provided, especially in a portion covering the upper body, both the auto and manual functions are provided. This has the effect of improving safety and giving the user a sense of security.

In the above embodiment, the case where the present invention is applied to a dry suit has been described. However, it is needless to say that the present invention can be applied to waterproof clothes such as a life jacket with an underwater buoyancy adjusting function and waterproof pants for fishing. That is. As described above, various preferred embodiments of the present invention have been described. However, the present invention is not limited to these embodiments, and it goes without saying that many more modifications can be made without departing from the spirit of the invention. That is.
