Abstract

PURPOSE:To enable a floating body to be easily detachable from the neck for preventing a drowning accident, by providing the floating body made up of a synthetic resin foaming agent with a round hole for inserting the neck, and further by connecting the round hole and the outer periphery of the floating body via an openable separating part. CONSTITUTION:In a circular dislike floating body 1 of a prescribed thickness made up of a synthetic resin foaming agent, a round hole 2 for inserting the neck is formed in its center, and the round hole 2 and the outer periphery of the floating body 1 are connected via a separating part (cutoff line) 3. And, when it is used, the right and left parts making the separating part 3 as a boundary are bent upward and downward respectively, and the floating body 1 is fitted around the neck in such a state as the round hole 2 is widened. In the fitted condition, since the floating body 1 works to push up the jaw and the back of the head above the surface of the water, the nose and mouth are prevented from being immersed under water. Further, when a lifeline is thrown, it can be connected to a hole 4. Thus, a drowning accident can be prevented.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a lifebuoy to be worn like a collar.

[Conventional technology and its drawbacks]

Conventional life floats are known as so-called life jackets or life jackets, which have floats on the torso, chest, and back, but this life jacket has a floating effect on the head and neck. Due to the scarcity, the head and neck were often submerged in water, making it impossible to breathe and causing death by drowning.

[Purpose of the invention]

Therefore, the present invention is based on the viewpoint that if the nose and mouth are kept above the water surface, the above-mentioned conventional drowning can be prevented. I am proposing a lifebuoy.

[Structure of the invention]

The structure of the present invention that solves the problems of the prior art is that a window hole for neck fitting is provided in the floating body, and the window hole and the outer end of the floating body are communicated via an openable and closable separation part. This article focuses on the characteristic life-saving floats.

[Example 1] (Figures 1 to 3) 1 is a circular plate-shaped floating body made of synthetic resin foam material (closed cell) with a required wall thickness. A window hole 2 for neck fitting is formed, and the window hole 2 and the outer end of the floating body 1 are communicated via a radial separation portion 3 (cut line).

Therefore, the action is to open the left and right floating body parts bordering on the separation part 3 by bending them up and down as shown in the imaginary lines in Figure 2 against elasticity, and to open the floating body through the opened separation part 3. By inserting it from the side of the neck, attachment of the floating body 1 to the neck is completed. Furthermore, upon release of the above-described bending operation, the separating portion 3 automatically butts against itself due to the elasticity of the floating body itself and maintains the closed state.

In the above-mentioned state, when you perform breaststroke or standing stroke as shown in Figure 3, the floating body 1 works to push up the chin and the back of the head above the water surface, so the nose and mouth will not be submerged in the water. . Reference numeral 4 denotes a hole for connecting a reins, and a string can be connected to this hole 4 to enable pulling of a swimmer.

[Embodiment 2] (Fig. 4) In this example, the length of the separating portion 3 is increased by providing the separating portion 3 in the tangential direction to the window hole 2, and the abutting contact area is increased due to this increase. This is a modified example in which the closing biasing force of 3 is increased to prevent the separation part 3 from opening unexpectedly due to resistance with water.

[Embodiment 3] (Fig. 5) In this example, square dovetail protrusions 3 and 3b are formed on the left and right abutting surfaces constituting the separation part 3, and both the dovetails 3a,
3b is engaged with peracid from the thickness direction of the floating body,
This is an example in which the closed state of the separating section 3 is maintained even more reliably when the floating body is used.

[Embodiment 4] (Fig. 6) In this example, arc-shaped dovetail protrusions 3c and dovetail concave lines 3d are formed on the left and right abutting surfaces constituting the separation part 3, and both dovetail protrusions 3c, 3d are formed. This is a modification of the third embodiment described above, in which the floating body 1 is engaged with peracid from the thickness direction of the floating body 1 to ensure that the separation portion 3 is kept in a closed state when the floating body is in use.

[Embodiment 5] (Figures 7 and 8) In this example, small holes 5 are formed through the floating body parts on the left and right sides bordering on the separation part 3, and a string 6 is pushed through the small holes 5. This is an example in which the closed state of the separation section 3 is reliably maintained when the floating body is used by tying the two.

[Embodiment 6] (Figures 9 and 10) In this example, headed pins 7 are arranged side by side on the left and right sides of one side of the floating body part bordering on the separation part 3, and the string 6 is tied to the headed pins 7. This is an example in which the closed state of the separating section 3 is reliably maintained when the floating body is used by tying the floating body.

[Embodiment 7] (Fig. 11) In this example, a mooring member 8, commonly called Velcro, consisting of a loop and a locking piece that wraps around and locks the loop, is provided on the left and right abutment surfaces constituting the separation part 3. This is an example in which the mooring ensures that the separation section 3 is kept in a closed state when the floating body is used.

[Embodiment 8] (Figures 12 and 13) In this example, the floating body 1 is formed of an air bag member having an air blowing port 9. Therefore, as the separation part 3, foam is formed at both end openings of the air bag member. Blocks 10 formed of a relatively hard material such as wood are fitted into each other, and dovetail protrusions 10a and 10b in the thickness direction of the floating body are provided on the abutting surfaces of both blocks 10, which engage each other with peracid. It was formed by

[Embodiment 9] (Figure 14) This example is an example in which a so-called light-emitting member 11 that reflects the irradiation of light such as a fluorescent film or light is provided on the entire surface of the floating body 1. It is designed to make people aware of this.

[Example 10] (Figures 15 to 18) In each of the previous examples, a circular floating body was illustrated, but it may be formed into a rectangular shape as shown in Figure 15 or a triangular shape as shown in Figure 16. You may.

Alternatively, the shape may be elongated in the front-rear direction as shown in Fig. 17. In this case, swimming, such as crawling, in which both arms are rotated parallel to the length of the body, is hindered by the arms hitting a floating object. It's incredibly convenient.

Further, as shown in FIG. 18, the outline of the floating body is formed in the shape of an animal's face so that children and the like can wear the floating body.

〔Effect of the invention〕

As described above, according to the present invention, the floating body can be easily attached to and taken off from the neck by opening and closing the separation part provided on the floating body, and when the floating body is attached to the water and enters the water, the part above the neck, The bag and mouth can be kept above the water at all times, thus eliminating drowning accidents caused by traditional life jackets.

It is also effective as a swimming ring, and has excellent features such as a simple structure.
