An embodiment of the exercise apparatus of the present invention will be described below with reference to additional drawings. As shown in Fig. 1, the exercise device 1 is composed of a sports equipment 2 such as a treadmill, a chamber 10, a sealing member 20, and a pressure adjusting device 30. Hereinafter, the front, rear, left and right directions will be defined using the direction that the user 40 of the exercise equipment 2 faces as the front.

In addition to the various treadmills that are generally commercially available, the sports equipment 2 can use various sports equipment such as an exercise bicycle. However, in order to be used in track and field training, it is desirable to produce suitable speed. The sports equipment 2 is disposed on the base 3. The base 3 is of a considerable size due to the configuration of the exercise equipment 2, and is configured to withstand even when the user 40 is training on the exercise equipment 2. The base 3 can also be assembled with a foldable foot 4 and a caster 5. Thereby, when the exercise device 1 is used, the extendable leg portion 4 can fix the base 3, and when the exercise device 1 is to be moved, by folding the leg portion 4, the caster 5 can be used to move to an arbitrary place.

Next, the chamber 10 will be described with reference to FIGS. 2 and 3. The chamber 10 is formed of a sheet having airtightness, and the end portion is assembled to the outer peripheral end of the base 3 to form a bag shape. A transparent sheet or an opaque sheet can be used for the sheet. Further, when an opaque sheet is used, it is preferable to provide a transparent window 11 formed of a transparent sheet in one of the front, rear, left and right portions. Thereby, the trainer can grasp the training state of the user 40 from the outside.

The upper end portion of the chamber 10 is formed by a circular opening portion 12 of a size that the user 40 can access in the lower body. As shown in FIGS. 4 and 5, an engagement ring 13 is attached to the inner peripheral end of the opening portion 12, and the engagement ring 13 has a predetermined width in which the tube portion 23 to be assembled of the skirt portion 22 to be described later can be engaged. . The engagement ring 13 is formed to have a smaller inner diameter than the opening 12 and a larger outer diameter than the opening 12 . Further, the engaging ring 13 is formed of a material having a relatively high rigidity, and is tightly joined to the sealing member 20 to hermetically seal the chamber 10. The inner peripheral end of the engagement ring 13 is assembled with a guard ring 14 that protects the skirt portion 22 to be described later and has a substantially circular cross section, and the outer peripheral portion of the engagement ring 13 is assembled to protrude from the chamber 10 around the entire circumference. Internal annular stop 15.

Further, as shown in Fig. 2, the pair of right and left sides of the opening portion 12 of the chamber 10 are provided with a pair of levers 16, 16 for vertically expanding and contracting the chamber 10. Each of the levers 16 is supported by one of the right and left sides of the base 3 and is movable up and down by the pair of slide bars 6, 6 and moves up and down along the slide bars 6, 6 to be held at any height on the slide bars 6, 6. on. Thereby, irrespective of the height of the user 40, the upper end of the chamber 10 can be located at the waist of the user 40. Further, as shown in Fig. 3, when the user 40 is to use the exercise device 1, the levers 16, 16 can be lowered to the vicinity of the lower ends of the slide bars 6, 6 to compress the chamber 10, whereby the user 40 can easily Through the opening 12 Enter the chamber 10.

Next, the sealing member 20 will be described with reference to FIGS. 4 and 5. The sealing member 20 is preliminarily attached to the user 40 when the exercise device 1 is used, and is formed by the pants portion 21, the skirt portion 22 integrally formed with the pants portion 21, and the tube portion 23 assembled to the outer peripheral portion of the skirt portion 22. . The pants portion 21 is made of a material excellent in stretchability or elasticity. In order to improve the fit when it is worn, it is preferable to use a material composed of a synthetic rubber such as a chloroprene rubber such as a wetsuit.

The skirt portion 22 is integrally formed with the pants portion 21 around the waist portion of the pants portion 21. The skirt portion 22 is formed larger than the inner diameter of the engagement ring 13 and is formed in a donut shape having a size smaller than the assembly position of the stopper 15, and can be put on by inserting the foot of the user 40 from the center opening. The pants portion 21 is loaded. The skirt portion 22 is formed by using a material having airtightness and overlapping the fabric by four layers. As will be described later, although the inside of the chamber 10 is made high pressure when the exercise device 1 is used, since the fabric is formed by stacking four layers of the fabric, even if the inside of the chamber 10 is high pressure, the skirt portion 22 can be controlled to expand, and the result is obtained by The expansion of the skirt 22 prevents the skirt 22 from being detached from the snap ring 13. Further, the tube portion 23 is formed of a ring-shaped material made of an elastic material such as polyurethane, and is assembled around the entire circumference of the outer peripheral end of the skirt portion 22 around the entire circumference.

Referring again to Fig. 1, the chamber 10 has a blower port 17 at the front, an exhaust port 18 at the rear, and a pressure adjusting device 30 is incorporated in the blower port 17. The pressure adjusting device 30 can use a blower such as a blower. Using the pressure adjusting device 30, the air outside the chamber 10 is sucked into the chamber 10 from the air blowing port 17, whereby the pressure in the chamber 10 can be increased. Further, when the pressure in the chamber 10 is to be lowered, the air in the chamber 10 can be discharged from the exhaust port 18 using the exhaust port 18 to reduce the pressure in the chamber 10. Thereby, the pressure in the chamber 10 is adjusted.

Further, in the chamber 10, in particular, a blower 31 is disposed in the outer cover of the front side of the sports equipment 2. The blower 31 sucks air into the chamber 10 to blow the wind from the front to the user 40. This wind is discharged from the exhaust port 18 provided behind the chamber 10, whereby the air circulating in the chamber 10 is caused to flow. When the exercise device 1 is trained, since the inside of the chamber 10 is hermetically sealed by the sealing member 20, the humidity in the chamber 10 rises by the sweating of the movement of the user 40 or the like, and the chamber 10 is often provided. The situation of internal suffocation. However, the air chamber 31 is disposed in the chamber 10, and the air in the chamber 10 is circulated, and the moisture in the chamber 10 is discharged from the exhaust port 18, whereby the humidity rise and the wet belt of the chamber 10 can be released. Unpleasant feelings. Further, since the wind from the blower 31 is directly blown to the foot of the user 40, the lower body of the user 40, particularly the foot, can be cooled.

Next, a method of using the exercise device 1 will be described. First, the user 40 inserts the two legs from the central opening of the skirt 22 to put on the pants portion 21, whereby the skirt portion 22 is located at the waist of the user 40. Next, as shown in Fig. 3, the lever 16 is lowered to lower the upper end of the chamber 10 to the vicinity of the base 3. Thereafter, the user 40 enters the chamber 10 through the opening portion 12, raises the lever 16, and raises the upper end of the chamber 10 to the waist portion and fixes it. In this state, the user 40 can reduce the diameter of the tube portion 23 and pass through the opening portion 12 to fit the skirt portion 22 into the chamber 10. At this time, the skirt portion can be deployed in the chamber 10 by the restoring force generated by the elasticity of the tube portion 23. Since the snap ring 13 is provided with the stopper 15, the tube portion 23 is left at the position contacting the stopper 15, and the position of the skirt portion 22 is determined inside the stopper 15. Moreover, since the outer diameter of the skirt portion 22 is larger than the inner diameter of the engaging ring 13, the tube portion 23 assembled to the outer peripheral end of the skirt portion 22 is engaged with the outer portion. The ring 13 is engaged, and the outer peripheral end of the skirt 22 is tightly engaged with the engaging ring 13. Thereby, the skirt portion 22 can be held at a predetermined position covering the opening portion 12, and the skirt portion 22 can be prevented from being detached from the engaging ring 13 by the skirt portion 22 being biased toward one side.

Thereafter, the user 40 operates an operation panel (not shown) at hand to operate the pressure adjusting device 30 and increase the pressure in the chamber 10. When the pressure in the chamber 10 is increased, as indicated by the arrow B in Fig. 5, the internal pressure acts on the skirt 22 to expand the skirt 22 and is pushed to the engaging ring 13, while the skirt 22 will It is just combined with the guard ring 14, whereby the skirt portion 22 is tightly engaged with the engaging ring 13 and the guard ring 14, and the opening portion 12 can be hermetically sealed. At this time, by the guard ring 14 assembled to the inner peripheral end of the engaging ring 13, the inner peripheral end of the engaging ring 13 can be prevented from contacting the cloth of the skirt portion 22 to damage the skirt portion 22.

As described above, since the chamber 10 and the sealing member 20 are separately provided in the present invention, the user 40 can previously place the sealing member 20 at the waist before entering the chamber 10, and the sealing member 20 can be easily worn and detached. Further, since the user 40 enters the chamber 10 with the sealing member 20 placed in the waist of the user 40, the user 40 can easily enter and exit the chamber 10. Further, by pressing the inside of the chamber 10, the internal pressure acts on the skirt portion 22, and the skirt portion 22 and the engaging ring 13 and the guard ring 14 are automatically and tightly engaged. Moreover, even if the user 40 performs the vigorous movement and the sealing member 20 operates together with the user 40, the tightness of the skirt 22 and the engaging ring 13 and the guard ring 14 can be maintained by the internal pressure, so that the inside of the chamber 10 can be maintained. The opening portion 12 is sufficiently airtight. However, since the chamber 10 and the sealing member 20 are different members, the user 40 is not limited to the chamber 10, and the user 40 can easily move.

Further, a blower 31 is disposed in the chamber 10, and an exhaust gas is disposed in the chamber 10 The port 18 thereby circulates the air in the chamber 10 and discharges the moisture in the chamber 10. Thereby, even if the user 40 who is training causes sweating in the chamber 10, the unpleasant feeling caused by the chamber 10 can be removed.

The embodiment of the present invention has been described above, but the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, the shapes of the opening portion 12 and the skirt portion 22 are circular, but the shapes of the opening portion 12 and the skirt portion 22 are not limited to a circular shape, and various shapes such as an elliptical shape, a rectangular shape, and a polygonal shape may be employed. At this time, the engaging ring 13 is formed in a shape similar to that of the opening portion 12, and the guard ring 14 and the stopper 15 are added, and the tube portion 23 is attached to the entire circumference, respectively, and is provided to engage the engaging ring 13 and the skirt portion 22. The shape. Further, the opening portion 12 and the skirt portion 22 do not necessarily have to have a similar shape, and the skirt portion 22 can be formed to be in close contact with the engaging ring 13 assembled at the inner peripheral end of the opening portion 12, and the airtightness can be maintained.

Further, in the above embodiment, the inner ring end of the engaging ring 13 is provided with the guard ring 14, but the skirt portion 22 and the engaging ring 13 can sufficiently maintain the airtightness of the opening portion 12, and the skirt portion 22 is provided. When the damage is not caused by the engagement ring 13, it is not necessary to provide the protection ring 14 in particular. Further, the skirt portion 22 may be protected by covering the inner peripheral end of the engaging ring 13 with a material having a low rigidity.

Further, the stopper 15 does not have to be provided around the entire circumference of the engaging ring 13, and may be provided only in a part of the circumferential direction of the engaging ring 13.
