It is a side view when the chamber of the exercise device of FIG. 1 is contracted. FIG. 2 is an enlarged view of the vicinity of a seal member of the exercise device of FIG. 1. It is an enlarged view of the A section of FIG.

  Hereinafter, an embodiment of an exercise device according to the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the exercise device 1 includes an exercise device 2 such as a treadmill, a chamber 10, a seal member 20, and a pressure adjustment device 30. Below, the front-back direction and the left-right direction are defined with the direction in which the user 40 using the exercise device 2 faces as the front direction.

  As the exercise equipment 2, various commercially available treadmills can be used, and various exercise equipment such as an exercise bike can be used. In addition, in order to use for athletics training, what can give a suitable speed | rate is preferable. This exercise device 2 is disposed on a pedestal 3. The pedestal 3 has a size sufficient to place the exercise equipment 2 and is formed to withstand even if the user 40 performs training on the exercise equipment 2. A foldable leg 4 and a caster 5 may be attached to the pedestal 3. Thereby, when using the exercise device 1, the leg 4 can be extended and fixed so that the pedestal 3 does not move. When the exercise device 1 is desired to be moved, the caster 5 is folded by folding the leg 4. Can be moved to any location using.

  Next, the chamber 10 will be described with reference to FIGS. The chamber 10 is formed of a sheet having airtightness, and an end portion is attached to the outer peripheral end of the base 3 and is formed in a bag shape. As the sheet, a transparent sheet or an opaque sheet can be used. Moreover, when using an opaque sheet | seat, it is preferable to provide the transparent window 11 formed with the transparent sheet in a part of front and rear, right and left. Thereby, the trainer can grasp the training state of the user 40 from the outside.

  A circular opening 12 is formed at the upper end of the chamber 10 so that the lower body of the user 40 can enter and exit. As shown in FIGS. 4 and 5, an engagement ring 13 having a predetermined width with which a tube 23 attached to a skirt 22 described later can be engaged is attached to the inner peripheral end of the opening 12. . The engagement ring 13 has an inner diameter smaller than the opening 12 and an outer diameter larger than the opening 12. Further, the engagement ring 13 is made of a material having high rigidity so that the chamber 10 can be closed in an airtight manner in close contact with the seal member 20. A protective ring 14 having a substantially circular cross section for protecting a skirt 22 described later is attached to the inner peripheral end of the engagement ring 13 from below, and the inner periphery of the chamber 10 is disposed on the outer peripheral side of the engagement ring 13. An annular stopper 15 is attached to the entire circumference.

  Further, as shown in FIG. 2, a pair of levers 16 and 16 for extending and contracting the chamber 10 up and down are attached to the left and right sides of the opening 12 of the chamber 10. Each lever 16 is supported by a pair of slide bars 6 and 6 attached to the left and right sides of the pedestal 3 so as to move up and down, and moves up and down along the slide bars 6 and 6 at an arbitrary height. It is held on slide bars 6 and 6. Thereby, regardless of the height of the user 40, the upper end of the chamber 10 can be positioned around the waist of the user 40. Further, when the user 40 uses the exercise device 1, the chamber 10 can be compressed downward by lowering the levers 16 and 16 to near the lower ends of the slide bars 6 and 6, as shown in FIG. As a result, the user 40 can easily enter the chamber 10 through the opening 12.

  Next, the seal member 20 will be described with reference to FIGS. 4 and 5. The seal member 20 is attached to the user 40 in advance when the exercise apparatus 1 is used, and includes a pant 21, a skirt 22 provided integrally with the pant 21, and a tube 23 attached to the outer peripheral end of the skirt 22. Is formed. A material excellent in stretchability and elasticity is used for the pants 21. In order to enhance the fit at the time of wearing, it is preferable to use a material made of a synthetic rubber such as chloroprene rubber used in a wet suit or the like.

  The skirt 22 is provided integrally with the pants 21 around the waist of the pants 21. The skirt 22 is formed in a donut shape that is larger than the inner diameter of the engagement ring 13 and smaller than the attachment position of the stopper 15. Can be installed. The skirt 22 is made of an airtight material, and is formed by layering the fabrics four times. As will be described later, when the exercise apparatus 1 is used, the inside of the chamber 10 is set to a high pressure. However, since the dough is formed by overlapping four layers, the skirt 22 may swell even if the inside of the chamber 10 becomes high pressure. As a result, the skirt 22 is prevented from coming out of the engagement ring 13 due to the swelling of the skirt 22. The tube 23 is a ring-shaped member made of an elastic material such as polyurethane, and is attached to the outer peripheral end of the lower surface of the skirt 22 over the entire periphery.

  Referring to FIG. 1 again, the chamber 10 is provided with a blower port 17 at the front and an exhaust port 18 at the rear, and a pressure adjusting device 30 is attached to the blower port 17. For the pressure adjusting device 30, for example, a blower such as a blower can be used. The pressure inside the chamber 10 is increased by using the pressure adjusting device 30 to suck in air outside the chamber 10 and send it into the chamber 10 through the blower port 17. When the pressure in the chamber 10 is lowered, the pressure in the chamber 10 is lowered by using the exhaust port 18 and exhausting the air in the chamber 10 from the exhaust port 18. Thereby, the pressure in the chamber 10 is adjusted.

  Further, a blower 31 is disposed in the chamber 10, particularly in a cover provided in front of the exercise equipment 2. The blower 31 sucks air in the chamber 10 and can apply wind to the user 40 from the front. The wind is exhausted from an exhaust port 18 provided at the rear of the chamber 10, whereby an air flow circulating in the chamber 10 is generated. During training by the exercise device 1, the inside of the chamber 10 is hermetically sealed by the seal member 20, so that the humidity in the chamber 10 rises due to sweating due to exercise such as running of the user 40, and the inside of the chamber 10 Often gets muddy. However, the air blower 31 is provided in the chamber 10 to circulate the air in the chamber 10, and the moisture in the chamber 10 is discharged from the exhaust port 18, thereby eliminating the unpleasant sensation due to the increase in humidity in the chamber 10 and stuffiness be able to. Moreover, since the wind from the air blower 31 directly hits the leg part of the user 40, the lower body part of the user 40, especially the leg part can be cooled.

  Next, a method of using the exercise device 1 will be described. First, the user 40 inserts both legs from the central opening of the skirt 22 and wears the pants 21 to position the skirt 22 on the waist of the user 40. Then, as shown in FIG. 3, the lever 16 is lowered and the upper end of the chamber 10 is lowered to the vicinity of the base 3. Thereafter, the user 40 enters the chamber 10 through the opening 12 and raises the lever 16 to raise and fix the upper end of the chamber 10 to the waist. In this state, the user 40 deflects the tube 23 to reduce the diameter, thereby passing the opening 12 and putting the skirt 22 into the chamber 10. At this time, the skirt 22 is expanded in the chamber 10 by the restoring force due to the elasticity of the tube 23. Since the engaging ring 13 is provided with the stopper 15, the tube 23 is held at a position where it comes into contact with the stopper 15, and the skirt 22 is positioned inside the stopper 15. Since the outer diameter of the skirt 22 is larger than the inner diameter of the engagement ring 13, the tube 23 attached to the outer peripheral end of the lower surface of the skirt 22 is engaged with the engagement ring 13, so that the outer peripheral end of the skirt 22 is engaged. Close contact with the coupling ring 13. As a result, the skirt 22 is held at a predetermined position covering the opening 12, and the skirt 22 is prevented from coming out of the engagement ring 13 due to the skirt 22 being biased to one side.

  Thereafter, the user 40 operates a handy operation panel (not shown) to activate the pressure adjusting device 30 to increase the pressure in the chamber 10. When the pressure in the chamber 10 increases, as shown by the arrow B in FIG. 5, the skirt 22 is inflated by being pressed against the engagement ring 13 at the same time as the skirt 22 is pressed against the engagement ring 13. As a result, the skirt 22 and the engagement ring 13 and the protection ring 14 are brought into close contact with each other, and the opening 12 is hermetically closed. At this time, the protective ring 14 attached to the inner peripheral end of the engagement ring 13 prevents the inner peripheral end of the engagement ring 13 from coming into contact with the fabric of the skirt 22 and damaging the skirt 22.

  As described above, in the present invention, since the chamber 10 and the seal member 20 are separately provided, the user 40 can place the seal member 20 in the waist before entering the chamber 10. The seal member 20 can be easily attached and detached. In addition, since the user 40 enters the chamber 10 with the seal member 20 positioned on the waist of the user 40 first, the user 40 can easily enter and exit the chamber 10. In addition, by pressurizing the inside of the chamber 10, an internal pressure is applied to the skirt 22, and the skirt 22 is automatically brought into close contact with the engagement ring 13 and the protection ring 14. Even if the user 40 performs intense exercise and the seal member 20 moves together with the user 40, the adhesion between the skirt 22, the engagement ring 13, and the protection ring 14 is maintained by the internal pressure. Sufficient airtightness of the inner opening 12 can be maintained. Furthermore, since the chamber 10 and the seal member 20 are separate members, the user 40 can easily exercise without clinging the chamber 10 to the user 40.

  Moreover, by providing the blower 31 in the chamber 10 and providing the exhaust port 18 in the chamber 10, the air in the chamber 10 can be circulated and the humidity in the chamber 10 can be discharged. Thereby, even if the inside of the chamber 10 is steamed due to sweating of the user 40 who performs training, discomfort caused by the sweat can be removed.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this Embodiment, A various change is possible unless it deviates from the meaning. For example, in the above-described embodiment, the shape of the opening 12 and the skirt 22 is circular, but the shape of the opening 12 and skirt 22 is not limited to the circular shape, and various shapes such as an elliptical shape, a rectangular shape, a polygonal shape, and the like. It can be made into the shape. At this time, the engagement ring 13 is formed in a shape similar to the opening 12, and the protection ring 14, the stopper 15, and the tube 23 extend over the entire circumference so as to follow the shapes of the engagement ring 13 and the skirt 22, respectively. Provided. Further, the opening 12 and the skirt 22 do not necessarily have a similar shape, and the skirt 22 is formed so as to be in close contact with the engagement ring 13 attached to the inner peripheral end of the opening 12 so that sufficient airtightness can be maintained. Anything is acceptable.
