Description

  The present invention relates to an exercise device, and more particularly to an exercise device that can exercise in a heated state.

  BACKGROUND ART It has been known that aerobic exercise is effective for enhancing muscle strength of the lower limbs or improving cardiopulmonary function. Further, as exercise equipment capable of performing aerobic exercise, for example, a treadmill for performing a walking exercise, an ergometer for performing a cycling exercise, and the like as disclosed in Patent Literature 1 are known.

U.S. Pat. No. 5,133,339

  Exercise generally occurs due to muscle contraction (muscle contraction). A substance directly involved in muscle contraction is adenosine triphosphate (ATP), and a substance which is greatly involved in ATP production is oxygen. As the exercise intensity increases, such as walking fast or lifting a heavy object, the number of recruited muscle fibers (neuromuscular units) increases, and ATP consumption in muscle cells increases. Therefore, the demand for oxygen increases. Oxygen is transported from respiratory organs to muscle cells by various factors. Since oxygen is ultimately transported to muscle cells by blood, the amount of oxygen transported is basically the amount of blood pumped by the heart ( Cardiac output). Thus, during exercise, the respiratory circulatory system is enhanced according to the exercise intensity.

  However, for example, lower limb muscle strength due to obesity is inadequate to exercise by its own weight, persons with lower limb disorders or temporary dysfunction due to surgery, sarcopenia due to aging or chronic disease, lower limb muscle strength A person who has decreased or a person whose heart function has decreased due to a heart disease or the like cannot exercise with a large exercise load, and simply exercises using an exercise device as disclosed in Patent Document 1. In such a case, there has been a problem that it is not possible to perform a sufficient exercise to cause the respiratory circulatory system to increase. As a result, there has been a problem that effective lowering of muscular strength of the lower limbs or improvement of cardiopulmonary function cannot be achieved.

  The present invention has been made in order to solve the above-mentioned problems, and provides an exercise apparatus that can provide a large exercise effect on respiratory circulation and metabolism even when exercise load is small.

  An exercise device according to the present invention has an exercise device that allows a user to exercise a predetermined lower limb, and a cover that has an opening provided corresponding to a position where the user exercises, and covers at least the lower body of the user. A sealing member for sealing the opening, and a heating device for heating air in the cover. The cover has heat insulation.

The exercise device of the present invention includes a heating device that heats the air in the cover. Since the user exercises by inserting the lower body into the cover during exercise, the lower body is warmed and the body temperature of the lower body rises. Since blood circulates throughout the body, a rise in body temperature in the lower body causes a rise in core body temperature (core temperature). On the other hand, the thermoregulatory center promotes sweating in an attempt to lower the elevated body temperature, and as a result, the respiratory circulatory system is enhanced. As described above, since the respiratory circulatory system is enhanced by increasing the core body temperature, a large exercise effect on respiratory circulatory metabolism can be obtained even with a small exercise load.

  In a preferred embodiment, the exercise device further includes a pressure adjusting device for adjusting the pressure in the cover, wherein the cover has airtightness, and the seal member hermetically seals the inside of the cover.

  With such a configuration, the inside of the cover can be pressurized. When the inside of the cover is pressurized, a force for lifting the user from below, that is, buoyancy is applied, and the weight applied to the lower limb of the user is reduced by the buoyancy, that is, the weight of the user can be relieved. . Therefore, even a person who cannot support his or her own weight (self-weight) due to a decrease in muscle strength of the lower limbs can exercise.

  In a preferred embodiment, the cover is constituted by a double sheet of a heat insulating sheet and an airtight sheet.

  In a preferred embodiment, the exercise device further includes a blower in the cover.

  With such a configuration, the air in the cover can be circulated, and discomfort due to stuffiness due to perspiration can be reduced.

  ADVANTAGE OF THE INVENTION According to the exercise apparatus which concerns on this invention, a large exercise effect regarding respiratory circulation metabolism can be obtained even in the state where exercise load is small.

  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 apparatus 1 covers the exercise equipment 2, the exercise equipment 2 and the lower body of the user U, has a cover 10 having an opening 12 through which the user U can enter and exit, and seals the opening 12. The apparatus includes a sealing member 20 for stopping, a heating device 30, and a pressure adjusting device 40. Hereinafter, the front, rear, left, and right directions are defined as the direction in which the user U using the exercise equipment 2 faces.

As the exercise equipment 2, various treadmills that are generally commercially available are used. The exercise equipment 2 is arranged on a pedestal 3. The pedestal 3 is large enough to dispose the exercise equipment 2 and is formed so as to be able to endure even when the user U exercises on the exercise equipment 2. A foldable leg 4 and a caster 5 may be attached to the pedestal 3. Thus, when using the exercise device 1, the legs 4 can be extended to fix the pedestal 3 so as not to move, and when the exercise device 1 is to be moved, the casters 5 can be folded by folding the legs 4. It can be moved to any place by using.

  Next, the cover 10 will be described with reference to FIGS. The cover 10 has an end attached to the outer peripheral end of the pedestal 3 and formed in a bag shape. The cover 10 is large enough to cover the exercise equipment 2 and the lower body of the user U.

  The cover 10 is configured by a double sheet of a heat insulating sheet 101 having heat insulating properties and an air tight sheet 102 having air tightness (see FIG. 5). Either the heat insulating sheet 101 or the airtight sheet 102 may be inside or outside, but in the present embodiment, the outer surface of the heat insulating sheet 101 is covered with the airtight sheet 102. As the heat insulating sheet 101, for example, a sheet made of polyethylene, polyester, polycarbonate, or the like can be used. As the airtight sheet 102, for example, a sheet made of nylon, vinylon, polyester tarpaulin or the like can be used. A transparent sheet, a translucent sheet, or an opaque sheet can be used for the heat insulating sheet 101 and the airtight sheet 102. When a translucent sheet or an opaque sheet is used, it is preferable to provide a transparent window 11 formed of a transparent sheet on a part of the front, rear, left and right. Thereby, the trainer can grasp the exercise state of the user U from outside.

  At the upper end of the cover 10, a circular opening 12 is formed at a position corresponding to the position where the user U exercises with the exercise equipment 2 and has a size that allows the lower body of the user U to enter and exit. An engagement ring 13 having a predetermined width and made of a highly rigid material is attached to an inner peripheral end of the opening 12. The engagement ring 13 has a flat ring shape having an inner diameter smaller than the opening 12 and an outer diameter larger than the opening 12. A protection ring 14 having a substantially circular cross section is attached to the inner peripheral end of the engagement ring 13 at a position below. Further, an annular stopper 15 which projects into the cover 10 and is formed by curving a plate material into a truncated conical shape having a small diameter on the lower side is attached to the entire outer circumference of the engagement ring 13.

  As shown in FIG. 2, a pair of levers 16 for extending and retracting the cover 10 up and down are attached to both left and right sides of the opening 12 of the cover 10. Each lever 16 is vertically movably supported by a pair of slide bars 6, 6 attached to the left and right sides of the pedestal 3, moves up and down along the slide bars 6, 6, and has an arbitrary height. It is held on slide bars 6,6. Thereby, regardless of the height of the user U, the upper end of the cover 10 can be positioned around the waist of the user U. When the user U uses the exercise apparatus 1, the cover 16 can be compressed downward by lowering the levers 16, 16 to near the lower ends of the slide bars 6, 6, as shown in FIG. Thus, the user U can easily enter the cover 10 through the opening 12.

  As the sealing member 20, any known sealing means can be adopted as long as the opening 12 can be hermetically sealed while the user U is in the cover 10. In this embodiment, as shown in FIGS. 4 to 6, the seal member 20 is attached to the user U in advance when using the exercise apparatus 1, and the pants 21, a flange provided integrally with the pants 21. 22 and a tube 23 attached to the outer peripheral end of the flange 22. The pants 21 are made of a material having excellent elasticity and elasticity. In order to enhance the fit at the time of wearing, it is preferable to use a material made of synthetic rubber such as chloroprene rubber used for wet suits and the like.

The flange 22 has a flat ring shape that is larger than the inner diameter of the engagement ring 13 and smaller than the mounting position of the stopper 15, and is provided integrally with the pants 21 around the waist of the pants 21. The flange 22 is made of, for example, a material obtained by laminating chlorobrene rubber on a jersey material, or a heat-insulating and air-tight material generally used for wet suits such as a flat skin. The flange 22 is formed by laminating a plurality of cloths made of the above-mentioned materials so as to withstand even if the inside of the cover 10 is pressurized by the pressure adjusting device 40.

  The tube 23 is formed in an annular shape having a size substantially equal to the outer diameter of the flange 22, and is attached to the outer peripheral end of the lower surface of the flange 22 over the entire circumference. The tube 23 is formed of an elastic material such as polyurethane.

  The heating device 30 is a device for heating the air in the cover 10 and is provided in the cover 10 as shown in FIGS. Any heating device known as a heating device such as a ceramic fan heater, a gas fan heater, a petroleum fan heater, a radiant ceramic heater, a panel heater, a hot air heater, and a heat pump hot air heater is used as the heating device 30. Can be. In order to efficiently raise the body temperature of the lower body of the user U inserted into the cover 10, it is preferable that heated air convects inside the cover 10. Therefore, the heating device 30 includes a ceramic fan heater, It is preferable to use a gas fan heater, an oil fan heater, a hot air blower, a heat pump hot air blower, or the like having a function of sending out hot air.

  The pressure adjusting device 40 adjusts the pressure inside the cover 10, and is composed of, for example, a blower such as a blower, and includes a blower tube 41. An air outlet 17 is formed in front of the cover 10, and the pressure adjusting device 40 is communicated with the inside of the cover 10 by inserting an air blower tube 41 into the air outlet 17 and attaching the same. The pressure inside the cover 10 is increased by using the pressure adjusting device 40 to inhale air outside the cover 10 and to send the air into the cover 10 from the air outlet 17 through the air duct 41. On the other hand, an exhaust port 18 that can be opened and closed is formed behind the cover 10, and an exhaust pipe 19 communicates with the exhaust port 18. When reducing the pressure in the cover 10, the pressure in the cover 10 is reduced by opening the exhaust port 18 and exhausting the air in the cover 10 from the exhaust port 18 through the exhaust pipe 19. Thereby, the pressure in the cover 10 is adjusted.

  In the cover 10, for example, a blower 50 is disposed in a cover provided in front of the exercise equipment 2. The blower 50 can inhale the air in the cover 10 and blow the wind to the user U from the front. The wind is exhausted from an exhaust port 18 provided at the rear of the cover 10 through an exhaust pipe 19, thereby generating a flow of air circulating in the cover 10. At the time of exercise by the exercise device 1, since the inside of the cover 10 is airtightly sealed by the seal member 20 and the air in the cover 10 is heated, the inside of the cover 10 is sweated by the user U walking. Is often increased, and the inside of the cover 10 is often stuffy. However, the blower 50 is provided in the cover 10 to circulate the air in the cover 10 and exhaust the moisture in the cover 10 from the exhaust port 18, thereby eliminating the discomfort caused by the rise in humidity and stuffiness in the cover 10. be able to. Further, since the wind from the blower 50 directly hits the lower limb of the user U, the lower body of the user U, particularly the lower limb, can be cooled.

As shown in FIG. 7, the exercise device 1 may be provided with a control device 60 for controlling the heating device 30, the exercise equipment 2, and the pressure adjusting device 40. The control device 60 measures the core body temperature and the heart rate of the user U, and controls the heating device 30, the exercise equipment 2, and the pressure adjusting device 40 so that the core body temperature or the target heart rate suitable for the user U is obtained. ing. For example, the control device 60 performs control to weaken the heating device 30 when the core body temperature is higher than the appropriate temperature, and to strengthen the heater 30 when the core body temperature is lower than the appropriate temperature. When the heart rate is higher than the target heart rate, the control device 60 reduces the inclination of the exercise equipment 2 (treadmill), decreases the speed, or increases the pressure adjustment device 40 to increase the unloading rate. Control to reduce the exercise load. Conversely, when the heart rate is lower than the target heart rate, the control device 60 reduces the unloading rate by increasing the inclination of the exercise equipment 2 (treadmill), increasing the speed, or weakening the pressure adjusting device 40. Control to increase the exercise load.

  Next, a method of using the exercise device 1 will be described. First, the user U positions the flange 22 at the waist of the user U by inserting both legs from the center opening of the flange 22 and piercing the pants 21. Then, as shown in FIG. 3, the lever 16 is lowered, and the upper end of the cover 10 is lowered to the vicinity of the pedestal 3. Thereafter, the user U enters the cover 10 through the opening 12 and raises the lever 16 to raise and fix the upper end of the cover 10 to the waist.

  In this state, the user U puts the flange 22 into the cover 10 through the opening 12 by bending and reducing the diameter of the tube 23. Since the tube 23 is formed of an elastic material, the flange 22 is expanded into the cover 10 by the restoring force due to the elasticity of the tube 23. At this time, since the exercise device 1 includes the stopper 15, the tube 23 stops at a position where the tube 23 hits the stopper 15, and is disposed inside the stopper 15. Thereby, the flange 22 having the tube 23 on the outer peripheral end is also positioned inside the stopper 15. Since the outer diameter of the flange 22 is larger than the inner diameter of the engagement ring 13, the tube 23 attached to the outer peripheral end of the flange 22 engages with the engagement ring 13 and is held at a predetermined position where the flange 22 covers the opening 12. Is done.

  Thereafter, the user U operates the operation panel (not shown) at hand to operate the heating device 30 and the pressure adjustment device 40 to heat the air in the cover 10 and to control the pressure in the cover 10. Enhance. When the pressure in the cover 10 increases, the inner pressure is applied to the flange 22 and the flange 22 expands and is pressed against the engagement ring 13 as shown by an arrow B in FIG. Stick together. Since the engagement ring 13 is formed of a material having high rigidity, the flange 22 is in close contact with the engagement ring 13 and the protection ring 14, so that the opening 12 is airtightly closed. At this time, the protection ring 14 attached to the inner peripheral end of the engagement ring 13 prevents the inner peripheral end of the highly rigid engagement ring 13 from contacting the fabric of the flange 22 to prevent the flange 22 from being damaged. .

  When the pressure in the cover 10 increases, buoyancy is applied to the user U, and the weight of the user U is released. On the other hand, the air heated by the heating device 30 convects to warm the lower body of the user U and raises the body temperature of the entire lower body of the user U. The body temperature that has risen in the lower body goes through the blood to the whole body and raises the core body temperature. Thereby, the core body temperature rises, and the user U can exercise while the weight is unloaded.

  Next, the subjects were allowed to perform a walking exercise, and the effect of releasing the weight and the effect of heating the inside of the cover 10 were verified.

  In Example 1, the body weight was unloaded by 50%, and the temperature of the air in the cover 10 was heated to 60 ° C. In Example 2, the body weight was not relieved (the weight was practically relieved by 5% for the sake of the experimental device), and the temperature of the air in the cover 10 was heated to 60 ° C. On the other hand, in Comparative Example 1, the weight was not relieved, and the air in the cover 10 was not heated. In Comparative Example 2, the weight was reduced by 50%, and the air in the cover 10 was not heated.

Under the unloading and heating conditions of Example 1, Example 2, Comparative Example 1, and Comparative Example 2, the subject performs a walking exercise at a speed of 6 km / h, and the eardrum temperature, heart rate, and oxygen, which are indicators of respiratory circulatory metabolism, Intake, cardiac output and respiratory rate were measured. The eardrum temperature was measured using a biological information monitor (Omron Corporation, HBP-2070) and an eardrum temperature probe (Nipro Corporation, Nipro CE Thermo CET-001 for right ear). The heart rate was measured using a biological information monitor (Omron Corporation, HBP-2070). Oxygen intake can be measured using a breath gas analyzer (Minato Medical Science Co., Ltd., AE-300S)
It measured using. The cardiac output was measured using a noninvasive impedance cardiac output meter (Manatec, Physioflow Lab-1). The respiratory rate was measured using an exhaled gas analyzer (Minato Medical Science Co., Ltd., AE-300S).

  8 shows the measurement results of the eardrum temperature, FIG. 9 shows the heart rate, FIG. 10 shows the oxygen intake, FIG. 11 shows the cardiac output, and FIG. 12 shows the respiration rate. The horizontal axis indicates time (min).

  As shown in FIG. 8 to FIG. 12, regardless of the presence or absence of unloading, heating increases the eardrum temperature, heart rate, oxygen intake, cardiac output, and respiratory rate substantially. Further, even when comparing Example 1 with Comparative Example 1, in Example 1, eardrum temperature, heart rate, oxygen uptake, cardiac output, and respiratory rate increased substantially or substantially as in Comparative Example 1. ing. From this, even in the state where exercise load is reduced by excluding weight, exercise with warming can provide a respiratory and circulatory metabolic response equal to or greater than exercise with weight. You can see that

  As described above, the exercise device 1 of the present embodiment includes the heating device 30 that heats the air in the cover 10. Since the user U exercises by inserting the lower body into the cover 10 during exercise, the lower body is warmed and the body temperature of the lower body rises. Since blood circulates throughout the body, a rise in body temperature in the lower body causes a rise in core body temperature. On the other hand, the thermoregulatory center promotes sweating in an attempt to lower the elevated body temperature, and as a result, the respiratory circulatory system is enhanced. As described above, since the respiratory circulatory system is enhanced by increasing the core body temperature, a large exercise effect on respiratory circulatory metabolism can be obtained even with a small exercise load. On the other hand, in the exercise device 1 of the present embodiment, the upper body is exposed to the outside of the cover 10 and the surrounding air is not heated, so that the upper body does not feel excessively hot and the user U is comfortable. Exercise can be performed.

  Furthermore, the exercise device 1 of the present embodiment can pressurize the inside of the cover 10 by including the pressure adjusting device 40 that adjusts the pressure inside the cover 10. When the inside of the cover 10 is pressurized, a force for lifting the user U from below, that is, buoyancy is applied, and the buoyancy reduces the weight on the lower limb of the user U, that is, releases the weight. it can. As a result, lower limb muscular strength decreased due to obesity due to insufficient lower limb muscle strength to exercise by its own weight, those with lower limb disorders or temporary dysfunction due to surgery, sarcopenia due to aging or chronic disease People can exercise.

  In addition, in the exercise apparatus 1 of the present embodiment, since the seal member 20 is attached to the waist of the user U, the trunk is fixed at the waist of the user U, and it is possible to easily maintain the standing posture. You can exercise with low balance.

  Further, by providing the blower 50 in the cover 10 and providing the exhaust port 18 in the cover 10, the air in the cover 10 can be circulated and the moisture in the cover 10 can be discharged. Thereby, even if the inside of the cover 10 gets stuffy due to sweating of the user U who exercises, the discomfort caused by the sweat can be removed.

Since the present invention is the exercise apparatus 1 as described above, firstly, it is possible to cause an individual who is obese and has insufficient leg muscular strength to exercise by his own weight to perform an effective exercise. That is, continuous aerobic exercise is indispensable for the treatment of obesity, and it is more useful to consume more energy (large ATP demand). However, it is usually difficult to secure effective exercise therapy without muscle strength to support weight, and if you exercise excessively, there is a risk that the exercise equipment such as knee joints will be damaged due to too heavy own weight There is also. However, by using the exercise device 1 of the present invention, the fat is gradually burned to promote weight loss, and after the weight loss is achieved to a certain extent, the unloading is gradually released and walking is performed, so that the muscle strength of the lower limbs is also increased. You can earn and go.

  Secondly, even a person who has a temporary dysfunction due to lower limb injury or surgery can exercise while relieving his or her own weight, so that rehabilitation can be started early. In particular, for athletes who want to return to sports as early as possible, the more exercise they take, the less their cardiopulmonary endurance decreases, but by starting rehabilitation as early as possible, it is expected that their physical strength will not be reduced as much as possible. it can.

  Third, effective exercise can be performed even for those who have experienced sarcopenia due to aging or a chronic disease. In other words, those who have come to sarcopenia may have reduced exercise capacity due to their own weight due to weakness of lower limb muscles, may not be able to perform effective aerobic exercise, but may also have injuries to the motor organs, or may easily injure the motor organs. There is. Since many of these people do not have exercise habits, they cannot suddenly exercise with high intensity. However, by using the exercise device 1 of the present invention, it is possible to exercise gradually working on the respiratory circulatory system, gradually release the unloading while accustoming to the body, increase the muscle mass together with cardiopulmonary endurance, and improve daily living activities. Can be raised.

  Fourth, peripheral arterial disease (PAD) patients can be given supervised exercise therapy, which has recently been recommended as an initial treatment. In other words, PAD patients generally exhibit ischemic symptoms during walking according to their severity, but walking exercise is optimal as an exercise program, and the greatest exercise effect is that it is almost impossible to walk due to ischemic symptoms (lameness pain). It is said to be obtained if you continue up to. On the other hand, exercise therapy for PAD cannot be continued in many cases because of the severeness of performing exercises that make it almost impossible to walk due to lame pain. In PAD, the coexistence of lifestyle-related diseases such as diabetes, hyperlipidemia, hypertension, arteriosclerosis, and cerebrocardiovascular disorders is extremely high, and exercise therapy is also useful for treating or controlling these diseases. Therefore, by using the exercise apparatus 1 of the present invention, it is difficult to cause ischemic symptoms in the lower limbs by unloading the body weight, so that the walking exercise is continued for a long time, and the whole body blood flow is increased by heating. Therefore, the effect of improving the blood flow of the ischemic limb can be expected.

  Fifth, exercise therapy can be adopted as cardiac rehabilitation. In other words, a patient suffering from a heart disease may also be unable to achieve aerobic exercise to reach a target heart rate because the function of the lower limb motors is also reduced. However, by using the exercise device 1 of the present invention, the target heart rate can be achieved earlier than in aerobic exercise by its own weight, the cardiac output and the oxygen intake increase, and the vascular resistance decreases due to the expansion of the arteries and veins. Because of increased evaporation such as sweating due to heat and heat, effects such as improvement of vascular endothelial function, peripheral circulation, peripheral oxygen utilization, etc., and reduction of preload / afterload on the heart can be expected.

  Sixth, it is also effective in rehabilitation of ataxia, a dysfunction that regulates voluntary movements of the limbs and trunk, seen in nervous system diseases such as cerebrovascular disease, cerebellar disease, prerequisite dysfunction, and Parkinson's disease. . In other words, many of those who have such a nervous system disease have symptoms such as being unable to walk straight, having poor balance ability, and being unable to control walking, but using the exercise apparatus 1 of the present invention, Since the trunk can be fixed, exercise therapy can be performed efficiently.

  Seventh, even for those who have difficulty in controlling body weight (particularly water) due to chronic renal failure, the exercise apparatus 1 of the present invention can be used to control body weight, congestion or edema due to increased evaporation such as sweating due to heat. The effect of improvement can be obtained.

As described above, by using the exercise apparatus 1 of the present invention, the exercise therapy is started without imposing a burden on the exerciser of the user U having a low exercise tolerance and having a low exercise intensity but securing a respiratory and circulatory metabolic response. In addition, as the exercise capacity increases, the unloading rate can be gradually reduced to finally obtain physical activity at atmospheric pressure.

  As described above, one embodiment of the present invention has been described, but the present invention is not limited to this embodiment, and various changes can be made without departing from the gist of the present invention.

  For example, in the above embodiment, the cover 10 is configured to cover the entire exercise equipment 2 and the lower body of the user U, but is not necessarily limited to this form. For example, in the case where the exercise equipment 2 has a grip or a seat, only an operation site where the user U operates the exercise equipment 2 with the lower limb is provided in the cover 10, and the grip U or the seat is provided. The cover 10 may be configured so that a part thereof is exposed outside the cover 10.

  Further, in the above-described embodiment, the cover 10 is formed in a bag shape by the heat insulating sheet 101 and the airtight sheet 102, but is not necessarily formed in a bag shape. For example, a cover that can hold a predetermined form can be formed by combining a heat insulating and airtight plastic plate. In this case, since the cover 10 has rigidity, the engagement ring 13 may not be provided.

  Further, in the above embodiment, the cover 10 has heat insulation and airtightness. For example, when it is not necessary to adjust the pressure in the cover, the cover 10 is formed only of the heat insulation sheet 101. It is possible to adopt a configuration having only the characteristics.

  Further, in the above embodiment, the shape of the opening 12 and the flange 22 is circular, but the shape of the opening 12 and the flange 22 is not limited to a circular shape, and may be various shapes such as an elliptical shape, a rectangular shape, and a polygonal shape. 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 are formed over the entire circumference so as to follow the shapes of the engagement ring 13 and the flange 22, respectively. Provided. In addition, the opening 12 and the flange 22 do not necessarily have to have similar shapes, and the flange 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 should do.

  In the above embodiment, the protection ring 14 is provided on the inner peripheral end of the engagement ring 13 and the stopper 15 is provided on the outer peripheral side of the engagement ring 13. However, the protection ring 14 and the stopper 15 are not necessarily required. . For example, when the airtightness of the opening 12 is sufficiently maintained by the flange 22 and the engagement ring 13 and there is no possibility that the flange 22 is damaged by the engagement ring 13, it is not necessary to provide the protection ring 14. . In addition, the flange 22 can be protected by covering the inner peripheral end of the engagement ring 13 with a material having low rigidity. Further, the stopper 15 does not necessarily need to be provided over the entire circumference of the engagement ring 13, and may be provided only on a part of the engagement ring 13 in the circumferential direction, or as long as the flange 22 does not come off from the engagement ring 13. The stopper 15 need not be provided.

Further, in the above embodiment, the pressure in the cover 10 is adjusted by the pressure adjusting device 40 provided outside, and the air in the cover 10 is circulated by the blower 50. Is not limited. For example, the pressure adjusting device 40 may be provided inside the pedestal 3, the outside air may be taken in from the side surface of the pedestal 3, and the air may be inserted into the cover 10 from the upper surface of the pedestal 3. Thereby, the exercise device 1 can be made more compact. Further, the blower 50 is not necessarily provided, and the pressure adjusting device 40 may have the function of the blower 50.

  In the above-described embodiment, the pair of levers 16 and 16 are provided on the left and right sides of the opening 12 of the cover 10 in order to extend and contract the cover 10 up and down.
