Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improved mouthpiece for diving equipment.

[0002]

[Prior art]

 Conventionally, there is a small diving tool that integrally comprises an appropriate number of small air cylinders. As shown in the side view of FIG. 3 and the plan view of FIG. 4, this diving equipment 1 includes a diving equipment body 2, a plurality of air cylinders 3 which are connected to the left and right of the diving equipment body 2 in an exchangeable manner, and a diving equipment. A regulator 4 connected to the upper part of the equipment main body 2, a mouthpiece 6 connected to the back side of the regulator 4, and a residual air amount alarm device 5 connected to the front side of the diving equipment body 2. .

The diving equipment 1 collects high-pressure air (for example, 200 kg / cm ² ) supplied from the air cylinders 3, 3 ... The pressure is reduced by and is guided to the trout piece 6.

The mouthpiece 6 is integrally formed of a soft material such as soft rubber or soft synthetic resin, and cantilever supporting pieces 8 and 8 project from both sides of the air supply port 7 connected to the regulator 4. A projecting piece 9 is provided on the inside of each cantilever support piece 8. The mouthpiece 6 is held by the mouth of the user by inserting the cantilever support pieces 8, 8 into the mouth of the user and biting the projecting pieces 9, 9.

[0005]

[Problems to be solved by the device]

 By the way, the diving equipment 1 may increase the number of air cylinders 3 to about four in order to prolong the diving time. In this case, the total weight of the diving equipment 1 increases and the water resistance during swimming increases. Therefore, the user needs to hold the diving equipment 1 firmly with his mouth through the mask piece 6 so that the diving equipment 1 does not sway. However, since the conventional mouthpiece 6 is entirely made of a soft material, it cannot be firmly held so as not to sway, and a comfortable dive may not be possible.

In order to solve the above problems, the present invention aims to provide a mouthpiece of a diving tool that can be firmly held by the mouth.

[0007]

[Means for Solving the Problems]

 Means adopted by the present invention is a mouthpiece of a diving tool, in which an air supply port and a cantilever support piece projecting from both sides of the air supply port are formed of a soft material, and the cantilever is provided from the air supply port. That is, the reinforcing core material is embedded over the support piece.

[0008]

[Action]

 Since the reinforcing core material is embedded in the portion from the air supply port to the cantilever support piece, its rigidity is increased. Therefore, the cantilever support piece can be firmly held by the mouth without wobbling.

[0009]

【Example】

 Hereinafter, a mouthpiece of a diving tool according to the present invention (hereinafter referred to as "the mouthpiece of the present invention") will be described based on the embodiments shown in FIGS. 1 and 2.

The improvement of the mouthpiece 16 of the present invention is that the reinforcing core material 20 is embedded from the air supply port portion 17 to the vicinity of the front end of the cantilever support piece 18. The mouthpiece 16 of the present invention is integrally molded of a soft material such as soft rubber or soft rigid resin except for the reinforcing core material 20, and cantilever supporting pieces 18 and 18 are provided to project from both sides of the air supply port portion 17, respectively. A protruding piece 19 is provided on the inside of the support piece 18. As the reinforcing core member 20, a thin strip plate (for example, a thickness of 0.3 mm and a width of 8 mm) such as stainless steel or a wire member is used, and holes 20a are formed at appropriate places. The hole 20a connects the outer layer 18a and the inner layer 18b of the cantilever support piece 18 separated by the reinforcing core material 20 and improves the bondability between the reinforcing core material 20 and the cantilever support piece 18. is there.

In the mouthpiece 16 of the present invention, the air supply port portion 17 is connected to the connection portion 4 a of the regulator 4 and is tightened with the band 21. In the mouthpiece 16 of the present invention, the cantilever support pieces 18 and 18 are inserted into the mouth, and the projecting pieces 19 and 19 are bitten to firmly hold the mouth piece of the user. The width dimension W of the cantilever support pieces 18, 18 can be adjusted by bending the portion 20b of the reinforcing core member 20 embedded in the root portion of the cantilever support piece 18.

[0012]

[Effect of device]

 As described in detail above, since the mouthpiece of the present invention can be firmly held by the mouth, it has a practical effect of being able to comfortably dive without diving the diving equipment.
