Abstract

PROBLEM TO BE SOLVED: To provide tools which make a swimmer enjoy underwater swimming for a long time using simple appliances. SOLUTION: This under water breathing apparatus is so constituted that a closed end life buoy having appropriate buoyancy is provided, one end of a breathing tube formed out of a tubular body in an appropriate length is positioned at a place above the life buoy, concurrently let its end part be inserted into a tube end holding fixture mounted to the life buoy so as to be held thereto, and the neighborhood of the other end of the breather tube is curved so as to be turned out an inhalation part, so that an underwater swimmer can thereby suck in atmosphere through the other end of the breathing tube, which is held in his mouth, wherein the atmosphere is sucked in from the breathing tube mounted onto the life buoy positioned over the water surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a respirator capable of staying in water for a long time by supplying air to an underwater swimmer using a tube.

[0002]

2. Description of the Related Art Conventionally, when diving underwater, there is a method of using a snorkel, a diving without using a tool for breathing,
A method using Aqualung is common, and a simple respiratory device using a tube as shown in the present invention has not been found.

[0003]

SUMMARY OF THE INVENTION Among the above means,
The dive lasts only for about 1 to 2 minutes, and the method using snorkel can swim for a long time near the water surface, but cannot be used when diving deeper. In addition, since Aqualung swims while carrying a cylinder, it cannot be continued if the air in the cylinder is consumed, and the equipment is also difficult. The present invention has been invented in order to solve the above-mentioned problems relating to the conventional underwater swimming means, and provides a simple respirator using a tubular body.

[0004]

According to the present invention, as a means for solving the problems, the present invention inhales the air sucked from the end of a ventilation pipe attached to a floating ring located above water from a ventilation pipe suction portion held by a submersible swimmer. It was configured to be able to. That is, a floating ring with a bottom having a moderate buoyancy is provided, and one end of a ventilation pipe formed of a pipe of an appropriate length is positioned above the floating ring,
The end is inserted and held in the tube holder attached to the floating ring, the other end is bent to be a suction portion, and the air sucked from the end of the ventilation pipe attached to the floating ring located on the water,
The underwater swimmer is configured so that it can be inhaled from the other end of the ventilation pipe. The present invention is an underwater respirator having the above configuration.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to use the present invention, a floating ring to which a ventilation pipe is attached is floated on water, the other end of the ventilation pipe is added to a mouth, and a ventilation pipe is attached to the head with an appropriate length of rubber band or the like. Is fixed. Then, when diving into the water as it is and sucking it through the suction portion while swimming, the atmosphere is sucked from the end of the ventilation pipe located above the water and supplied to the swimmer. Then, you can exhale into the water through the nostrils and freely swim in the water while continuing this breathing.

[0006]

Embodiments of the present invention will be described below. In the drawing, reference numeral 1 denotes a floating ring, which is a hollow donut-shaped ring.
2 is a ventilation pipe formed of a soft synthetic resin having an appropriate inner diameter, having a length commensurate with the diving depth, one end of which is located above the floating ring, the other end is curved and the other end is It serves as a suction unit for the swimmer to take in the air while holding it in his mouth. Reference numeral 3 denotes a fixed belt, the end of which is fixed near the end of the ventilation pipe. 4
Is a tube end cover, which extends from the lower part of the hollow hemisphere toward the center.
A stay 4a is fixed to the inner surface of the stay, and the upper portion of the short pipe is fixed to the stay, and is inserted and held at the upper end of the ventilation pipe. Reference numeral 5 denotes a tube holder, which has support rods 5b obliquely arranged on the outer peripheral surface of a short pipe 5a having an inner diameter substantially the same as the outer diameter of the ventilation pipe, at the lower end of the support rod, a floating ring outer peripheral surface. A curved plate 5c of a predetermined width having a curved inner surface similar to that described above is fixed. In addition, small diameter through holes are respectively formed near both ends of the curved plate, and a string 5d is connected in the through holes. As shown in FIG. 4, this cord is used to connect the ends thereof to each other to attach the pipe end holder to the floating ring. By unwinding the cord, the two articles can be separated. And the short pipe 5
A through hole is also provided in the vicinity of the upper end of a, and a string 5e is similarly tied to this through hole. By wrapping around the upper end of the ventilation pipe and tying each other's strings, the ventilation pipe is connected to the pipe end holder. Can be fixed. Numeral 6 denotes a water immersion preventing portion, in which a closed short tube is fitted and fixed at an appropriate position of the ventilation tube, and an elastic sphere 7 is positioned in the short tube so as to be able to reciprocate in a predetermined direction. The elastic sphere is formed of a water-impermeable foamed plastic having a diameter slightly larger than the inner diameter of the short pipe and the inner diameter of the ventilation pipe, and pull cords 8 and 9 are attached to the side surfaces thereof at symmetric positions. In addition, an insertion hole 10 lined with a non-permeable and elastic material is provided at the center of the closed portion of the short tube and at a predetermined position of the ventilation tube, and the drawstring is positioned in the insertion hole. I have. The above is one embodiment of the present invention.

Although the main functions of the present invention have been described above,
In this example, a water intrusion prevention part is provided to minimize the intrusion of water into the ventilation pipe when the end of the ventilation pipe comes off the mouth. As shown in FIG. 5, the water immersion preventing part has an elastic sphere positioned in the closed short tube, and when the water starts to enter from the mouthpiece, pulling the drawstring 8 causes the elastic sphere to move and pass through. The airway is closed, and the sphere is slightly expanded by elasticity, so that water can be prevented from entering. You can then float above the water, drain the water, and dive again. In addition, it can return to an initial state by pulling the drawstring 9, and can breathe. In addition, the closed short pipe and the ventilation pipe are provided with an insertion hole for passing the drawstring, and the inner surface of the insertion hole is lined with an elastic material, so that water does not enter from this portion. In this example, the tube end holder shown in FIG. 4 is used. The tube end holder can be detachably attached to the floating ring with a string, and the short tube 5a and the upper end of the ventilation tube can be fixed and detached with the string. Therefore, it is possible to separate the floating ring, the pipe end holder, and the ventilation pipe as required. In this example, since the pipe end cover is configured to be attachable to the upper end of the ventilation pipe, it is possible to prevent rainwater and the like from entering from the ventilation pipe end. The fixed belt in this example is provided for attaching a ventilation pipe to the head as shown in FIG. Fig. 7 shows the use condition of this example. If one end of the safety rope is tied to the float and the other end is tied to the swimmer's body, this string can be pulled quickly in an emergency to quickly ascend. Can be. As described above, underwater swimming can be freely enjoyed by the present invention.

[0008]

According to the present invention, by selecting the length of the ventilation pipe appropriately, it is possible to enjoy swimming underwater for a long time and to provide a useful article which can be freely used physically by using simple equipment. can do.
