Description

[Detailed description of the invention] (Field of industrial application) This invention is used for basic training of various sports in water, exercise for functional recovery training for physically disabled persons, underwater exercise for natural childbirth of expectant and nursing mothers, etc. 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 limb movement 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 structure.
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.

(Problem that the invention seeks 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 buffer space on the body surface to reduce the impact on the body, or to keep the upper body above the water surface, and takes a floating position on the back to prevent the wearer from drowning. It turns out.
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.

In addition, if the wearer is obese or pregnant, it is necessary to have something that fits the person's waist circumference and body shape, and a single wearable device can also be used to accommodate changes in body shape depending on the degree of obesity or pregnancy. There is a problem that cannot be addressed.

(Means for solving the problem) The vest of the present invention to solve the above problem has two armholes on the upper left and right sides through which the wearer's arms pass.
left and right front parts 3a and 3b having mutually openable and closable free ends that hang down to the waist of the wearer and cover substantially the entire abdomen from left and right, overlapping the front of the body, and the front part 3a. , 3b are connected on the back side, and a vest-like main body 1 made of a water-resistant elastic member is provided, which has a back part 4 that covers the back side of the body, and the lower part of the back part 4 is not connected to the front parts 3a and 3b. The pants section 6 is connected to the front section 3a, and a floating section having elasticity that gives buoyancy to the wearer from the front side and the back side of the body in water is formed inside the front section 3a, 3b and the back section 4. At the overlapping part between the front part 3b and the front part 3b, there is an engaging/disengaging part 5 made of a velvet fastener for freely adjusting and setting the trunk diameter of the vest-like main body 1 when the two are overlapped.
A, 5b are provided.

(Function) The flotation vest of the present invention is put on by the wearer by opening the upper part of the main body 1, passing the pants part 6 through the crotch, and setting the front parts 3a and 3b with the detachable parts 5a and 5b. When the wearer wears the pants and enters water with a depth equal to or greater than the wearer's body and a space wide enough to allow body movements, buoyancy is generated in the front and rear floating parts, and this buoyancy is directly directed downward from the body through the pants part 6. The wearer is supported from above to allow the wearer to float forward in the water in a bent-over position, thereby enabling free physical movement in the water.

(Example) To explain in detail the embodiments shown below, FIGS. 1 to 4 show the first embodiment of the present invention, and the flotation vest is made of a foamed tree sheet that is highly elastic, water resistant, and non-absorbent. A vest-shaped main body 1 is formed by adhesively covering the front and back sides with resin cloth, etc., and armholes 2 for passing the wearer's arms are provided on the left and right shoulder sides of the main body 1.
is formed.

The main body 1 has front parts 3a and 3b divided into left and right sides, which cover the front side of the wearer's body from the chest to the waist from the left and right sides.
It consists of a back part 4 which is connected at the outer end and the upper end of 3b and covers the wearer's back up to the waist. And, on the overlapping surfaces of the lower ends of the front parts 3a, 3b, there are attached detachable parts 5a, 5b which form a pair of horizontally long band-shaped velvet fasteners, and correspond to the size of the wearer's torso. The structure is such that each front part 3a, 3b can be set with an arbitrary trunk diameter.

The upper ends of the front parts 3a and 3b extend into a V shape to form a neck hole through which the wearer's head comes out, and at the center of the lower end of the back part 4, the front end is inserted between the wearer's crotches and the front end is inserted into the left front. A pants portion 6 is extended to be fixed at the lower end of the portion 3a, and the pants portion 6 is preferably made of a particularly stretchable material so that it can be easily fitted to the wearer's inner thighs, and after wearing the flotation vest. The structure is such that the buoyant force generated in the pants gives buoyancy to the body through the pants section 6.

At the tip of the pants section 6 and at the lower end of the inner surface of the left front section 3a, there are provided engaging and disengaging sections 19a and 19b consisting of a pair of velvet fasteners that correspond to each other. A detachable part 1 on the front part 3a side is provided so that the fixing position can be moved from side to side.
A plurality of 9b are attached to each other with a fixed left and right width at the attachment position, and furthermore, the engagement part 19b is attached to the pants part 6.
2 so that the side engaging/disengaging portion 19a is fixed on both the front and rear surfaces.
Two layers of velvet fasteners are sewn together to improve adhesion.

As shown in FIGS. 2 and 3, patch cloths 8 and 9 are applied to the inner surfaces of the front parts 3a and 3b and the back part 4 of the main body 1 from the inside, and the outer periphery of the cloths 8 and 9 are lined with seams 10.
A floating body 14 or 15 is provided which is sewn integrally with the main body 1 and is adhesively fixed on the entire contact surface.

The floating bodies 14 and 15 have external shapes as shown in FIGS. 2 and 3, have a certain thickness, are water resistant,
It is made of a plate made of a foamed resin material that is highly elastic and non-absorbent, and constitutes a lightweight floating section that provides a certain level of buoyancy to the wearer.
On the other hand, the size or material of the floating body 15 on the back side is selected so as to provide the same or higher buoyancy. Reference numeral 18 denotes a hemming section made of stretchable cloth that reinforces the cut end of the main body 1.

The flotation vest constructed as described above allows a person who exercises in water as described above to
Remove the pants and wear the pants with the front parts 3a and 3b open, turn the pants part 6 forward and attach and release the parts 19a and 1.
9b fixes the vest-like body 1 to the body, and the wearer enters water at a depth at least as deep as the wearer's body and exercises by floating in a substantially upright or forward-leaning position. .

FIG. 5 shows a second embodiment of this invention. In this example, the pants section 6 has left and right crotch holes 13 in the shape of ordinary seawater pants, and the front waist circumference end 6a of the pants section 6. , 6a are sewn on both sides of the lower end of the back surface. At the upper end of the front side of the pants portion 6, a locking/disengaging section 1 consisting of a plurality of fastener pieces that locks/disengages in correspondence with the hooking/disengaging section 19b on the front side 3a side.
9a, 19a, . . . are provided at appropriate intervals, and the structure is such that the waist circumference of the pants portion 6 can be expanded and contracted in accordance with the size of the wearer's waist circumference, and the lower end of the front portion 3a can be set accordingly.

In this embodiment, the pants part 6 itself is already integrally formed with the vest-like part 1, so it has the advantage of being easy to wear and not bulky on the front side, and also making it easy to move the body.

(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 carried out safely and naturally by bending forward with only the head exposed underwater. It has the advantage that it is effectively performed using the resistance and pressure of water in a comfortable posture, and that it is performed without the physical burden of supporting body weight, and that only the necessary parts of the body are trained. A pool for this purpose needs to be at least as deep as a person's height and wide enough to allow physical movement.

In particular, the pants section at the bottom of the main body is configured to fit around the outer circumference of the lower abdomen and directly support the body weight using buoyancy, allowing for smooth execution of the various underwater training exercises mentioned above, and the front section can be completely opened and closed on both sides. Moreover, since they can be set overlapping at any desired position, it is possible to freely accommodate unique body shapes such as those of obese people and pregnant women. In addition, the left and right front parts 3a and 3b fit almost the entire frontal abdomen of the wearer and are tightened without force, and since this part is covered twice, it has the advantage of being able to sufficiently protect and keep warm the abdomen of people with disabilities, pregnant women, etc. be.
