Description

[Detailed explanation of the invention] <Industrial application field> This invention is used for basic training of various sports in water, exercise for functional recovery training for physically disabled persons, etc., and underwater exercise for natural childbirth for expectant and nursing mothers. This invention relates to a flotation vest worn by an athlete to keep the head above the water surface while the body is in an upright hunched position.

<Prior Art> Water provides greater resistance to the movement of limbs than air. Therefore, swimming and other water sports that involve submerging body parts in water have been said to be very beneficial for muscle training.

However, muscles develop depending on how you train them.
This means that muscle development through swimming, cycling, and weight training is an overall effective secondary method of training for people who do not make these movements their primary sports and activities, but It is not possible to develop the necessary muscles immediately.

Therefore, in order to perform proper training, athletes,
Alternatively, sometimes the patient needs proper biomechanical exercise to develop muscle tissue.
For example, in order to strengthen the muscles necessary for running, it is effective to run while floating in the water instead of swimming.

Ski vests and life jackets have conventionally been used as flotation devices for such exercises.

<The problem that the invention aims to solve> However, the flotation devices to date have not been designed to perform this type of training, and have been developed with safety in mind. Ski vests and life jackets are commonly used as flotation devices.
It is created only to create a cushioning space on the body surface to reduce the shock applied to the body, or to keep the upper body above the water surface, and allows the wearer to take a floating position on his back to prevent drowning. become. Therefore, the wearer has no choice but to adopt an impossible posture in order to repeatedly perform exercises such as running or aerobics underwater.

Additionally, such equipment limits the freedom of movement needed to perform running and aerobics correctly. Because of these shortcomings, people who use standard ski vests and life jackets to exercise and train themselves in the water are forced into unnatural positions by these flotation devices. Therefore, they cannot use their muscles the way they use them in their sports.

Such devices are bulky and uncomfortable. Furthermore, because these flotation devices are constructed to keep the wearer above the water, the upper body, including the arms and shoulders, is above the water surface and the wearer does not benefit from the increased resistance provided by the water. do not have.

<Means for solving the problem> The flotation vest of the present invention to solve the above problem has a neck hole 7 and left and right arm holes 2 at the top.
and a split 13 connected to the neck hole 7 and extending to the vicinity of the wearer's lower abdomen, each of the left and right sides of the split 13 being front parts 3a, 3b, and the front parts 3a, 3b.
A vest-like main body 1 is formed of a water-resistant elastic member, and has a back part connected to the side edges of the wearer to cover the back of the wearer, and a pants part 6 having leg holes 19 at the lower end. The front parts 3a and 3b are provided with a detachable part 5 made of a velvet fastener that can be attached and detached so that the trunk diameter of the vest-like main body 1 can be freely adjusted on the other front part, straddling the split 13. , 3b and the back part 4 are provided with independent bag-like parts 11 and 12, respectively, and the bag-like parts 11,
The floating body 12 is characterized in that floating bodies 14 and 15 each made of a foamed resin material are housed in such a manner that the buoyancy on the back side 4 is larger than the total buoyancy on the front parts 3a and 3b.

<Function> The flotation vest of the present invention opens the upper part of the main body 1 and passes the wearer's legs and torso through the front part 13 or further closes the shoulder part 20 and connects the torso diameter with the engaging part 5 made of velvet fasteners. When the wearer enters water that is at least as deep as the wearer's height and wide enough to allow physical movement, buoyancy is generated in the front and rear floating parts, and this buoyancy The back side is larger than the front side, and the pants part 6
The wearer supports the wearer's body directly from below, allowing the wearer to float forward in the water in a bent-over position, thereby enabling free physical movement underwater.

〈Example〉 To explain in detail the embodiment shown below, Figs. 1 to 4 show the first embodiment of the present invention, and the flotation vest is made of a foamed resin sheet with high elasticity, water resistance, and non-water absorbency. A vest-shaped main body 1 is formed of a member whose front and back surfaces are adhesively covered with resin cloth or the like, and armholes 2 through which the wearer's arms pass are formed on the left and right shoulder sides of the main body 1.

The main body 1 covers the front side of the wearer's body from the chest to the waist, and is divided into left and right front parts 3a and 3b via a vertically formed split 13 in the center.
and a back part 4 which is connected at the outer ends and upper ends of the front parts 3a, 3b and covers the wearer's back up to the waist, and the front parts 3a, 3b are opened and closed from the left and right at the center of the front. They are butted together via a vertical split 13, and can be adjusted and locked according to the diameter of the wearer's torso using a locking/disengaging portion 5 made of velvet fastener.

The upper abutting ends of the front parts 3a and 3b form a neck hole 7 that expands in a V-shape and exposes the wearer's head;
A pants section 6, which is worn through the wearer's thighs, extends from the lower ends of the front sections 3a, 3b and the back section 4, and the pants section 6 has leg holes 19 for easy fitting to the wearer's inner thighs. The structure is such that the buoyancy generated in the flotation vest gives buoyancy to the body through the pants portion 6 after being worn.

As shown in FIG. 2, padding cloths 8 and 9 are applied to each of the front parts 3a and 3b and the back part 4 of the main body 1 from the inside, and the outer peripheral edges of the main parts 1 and 1 are attached at seams 10.
The bag-like part 11 or 12 is formed by sewing the bag-like part 11 or 12 integrally with the bag-like part 11 or 12.
A floating body 14 or 15 as shown in the figure or FIG. 5 is enclosed and accommodated.

As shown in FIG. 4, the floating bodies 14 and 15 are made of plates made of foamed resin material having a constant thickness and having high water resistance, elasticity, and non-water absorbing properties. It is made of a lightweight material that provides a certain level of buoyancy to the wearer, and the buoyant body 15 on the back side is sized or made of material so as to give the same or greater buoyancy to the buoyant bodies 14 on the front side. is selected.

As described above, the bag-shaped parts 11 and 12 and the floating body 14,
Reference numeral 15 constitutes a flotation section that provides buoyancy to the vest-shaped main body 1. Reference numeral 18 denotes a border made of cloth or the like that reinforces the cut end of the main body 1.

The flotation vest configured as described above is worn on the body by a person who exercises in water as described above, with the detachable part 5 removed and the front parts 3a and 3b open.
The wearer enters water that is at least as deep as his/her height and exercises while floating in a substantially upright or forward-leaning position.

Figures 6 to 8 show a second embodiment of this invention, which is a flotation vest exclusively for women with a front section 3.
There is no split 13 between a and 3b, they are connected with elastic fabric so that the trunk diameter can be adjusted freely, and the front part 3
There are many "gussets" 20 in the fabric around the part corresponding to the wearer's nipple in a and 3b.
A floating body 14 is formed and inserted here.
It is formed into a cup shape that protrudes forward, and the floating part on the front is shaped to correspond to a woman's bust.

In this embodiment, one shoulder portion 20 is connected to the upper and lower connecting pieces 20a, 20 so that the neck hole 7 and either the left or right arm holes 2, 2 are continuous holes.
The connecting pieces 20a and 20b have one end that can be attached to and detached from the other from above and below. so that it is sandwiched and joined to
Engagement/disengagement portions 21a, 2 made of velvet fasteners
1b is attached to simplify the design of the front portions 3a and 3b and to improve adhesion to the body.

In addition, it is also possible to easily make the body diameter adjustable by inserting a highly elastic rubber band-like material in the vertical direction on the side surface of the main body 1.

<Effects of the invention> As a result of the above-mentioned structure of this invention, underwater basic gymnastics, exercise, functional recovery training, and exercises for natural childbirth for expectant and nursing mothers can be performed safely and naturally by bending forward with only the head exposed underwater. It has the advantage that it is effectively performed using water resistance and water pressure in a comfortable posture, and that it is performed without the physical burden of supporting body weight, and only the necessary parts of the body are trained. For this reason, it is sufficient for the pool to be at least as deep as a person's height and wide enough to allow physical movement.

Furthermore, the pants section at the bottom of the main body is designed to fit around the outer periphery of the lower abdomen without being bulky, and directly supports the body weight with buoyancy, making it possible to perform the various underwater training exercises mentioned above smoothly.

In addition, this flotation vest has the advantage that the torso diameter can be freely adjusted using velvet fasteners in the front section, so it can easily accommodate changes and differences in the wearer's body shape.
