Description

[Detailed description of the invention] This invention relates to an air valve device installed on a rubber boat. Various types of air valve devices for rubber boats are known, but the valve body is exposed on the surface of the rubber boat. Therefore, items that may cause air leakage or injury to the user if they come into contact with the equipment, items that are not suitable for use in cases where air blowing and exhaust operations are troublesome and an emergency is required, and items that are not suitable for use when an emergency is required Many of them had many parts and did not take into account actual use on the water, such as those that could become unusable if parts came off or were lost.

The present invention overcomes the above drawbacks, without being exposed to the surface,
It is an object of the present invention to provide an air valve device which can perform air blowing and exhaust operations extremely easily, has no parts coming off, and is suitable for practical use.

The present invention will be explained with reference to an embodiment shown in the drawings. 1 has a required inner diameter and depth, and a ventilation hole 2 is provided in the center of the bottom.
It is made of a rubber member with a flange 3 for attachment to be adhered to a rubber boat on the outer periphery of the upper end, and a seat plate 5 with a tube shaft 4 having the required inner diameter and length erected on the upper center surface is buried and fixed in the inner bottom part. The opening at the lower end of the tube shaft 4 communicates with the ventilation hole 2,
A cap nut-shaped nut 7 is screwed onto the screw 6 provided on the outer periphery of the upper half of the tube shaft, and a ventilation notch 9 is provided at the periphery of the cap 8 at the upper end of the nut. A valve seat 10 for opening and closing the upper end of the tube shaft 4 is attached, and a stopper 12 for removing the nut is provided on an annular ridge 11 provided at the lower end of the nut.

Inside the upper end opening 16 of the member 1, a bag spanner-shaped insertion opening 15 that fits a nut 7 provided on a rubber joint 14 connected to an air inlet pipe 13 is inserted and connected as desired.

Since the present invention is constructed as described above, as shown in FIG. 8, an opening equal to the outer diameter of the member 1 is provided at a suitable location in the air sac 17 forming the boat, and the member 1 is fitted into the air sac through the hole. If the flange 3 is adhered to the surface of the air bladder with adhesive, the member 1 is integrated with the air bladder, and the valve body mounted inside the member is below the surface of the member 1 as shown in FIG. Even if an object touches the upper end surface of the air bag, the nut 7 will not loosen, and there is no risk of air leakage, and since it will not come into contact with the human body, it will save time and prevent injury to the user.

However, if you want to freshly introduce or replenish air, insert the insertion port 15 of the joint 14 connected to the tip of the air injection pipe 13 into the gap 16 from the upper end opening of the member 1, and the bag spanner The shaped insertion port 15 fits the nut 7, so when the joint is rotated to the left, the nut 7 rotates and rises along the thread 6 of the tube shaft 4, so that the valve seat that was in close contact with the opening at the upper end of the tube shaft 10 is separated from the tube axis, so if compressed air or an air pump is used to pump air through the air inlet tube 13, the air will flow from the air inlet tube through the notch hole 9 provided on the periphery of the cap at the upper end of the nut, through the tube axis 4, and into the air sac 17. When the air supply is finished, turn the joint 14 to the right and screw the nut 7 into the thread of the tube shaft, and the valve seat 10 will come into close contact with the opening at the upper end of the tube shaft 4, allowing ventilation. It closes the mouth.

After inserting the insertion port 15 of the aiming air inlet pipe 13 into the gap 16, rotate the joint 14 to the left. ,ff'fE
, and if you want to stop the insufflation after the end of insufflation or even during insufflation, you can stop insufflation simply by rotating the joint to the right.

The aeration operation is thus considerably simplified.

In addition, when removing the air inside the air bag, insert the insertion port 15 of the joint 14 from the upper end opening of the member and turn it to the left. The nut 7 will rise and the valve seat 10 will be opened, so that the air inside the air bag can be removed. The air is discharged into the outside air through the notch hole 9, and the operation is extremely simple.When the nut fitted into the insertion port 15 reaches a certain limit, the nut fitted into the insertion port 15 is removed from the tube shaft by the action of the stopper. There will be no withdrawals, so there is no need to worry about accidentally leaving Natsu and losing him.

With conventional air valves, when inflating, the operation of attaching or removing the inlet pipe and the operation of opening and closing the valve are separate operations, which is time-consuming.

As described above, according to the present invention, the installation of the inlet pipe or the removal operation and the opening/closing operation of the valve can be performed almost simultaneously, so the inlet operation is much easier than in the conventional technology, and the valve body is It is safe because it is located under the surface of the boat, and has the effect of making it a truly practical air valve device without worrying about losing parts.
