In general, various types of exercise equipment have been developed and used, and there are exercise equipment for aerobic exercise such as treadmills and weight exercise equipment for strengthening strength, but weight exercise equipment can selectively bite a plurality of weight blocks on a wire. And an exercise device connected to the wire so that the user can exercise the muscle.

Looking at the various conventionally developed exercise equipment through the literature as follows.

The use of such exercise equipment can be used by the elderly, as well as by the elderly or for physical rehabilitation, because the use of exercise equipment can be used for the elderly or rehabilitation therapists. More and more safety accidents and damages are high.

Since the weight exercise device is to pull the weight block by force and strengthens the muscle strength, there may be a risk of accidents such as a collision or shock when the weight block is returned, and the weight or weight of the weight block must be continually burdened by the joints or muscles. It may cause abnormalities or damage.

In addition, since the weight block size is limited, it is difficult to adjust the weight delicately even if the weight block is added or lowered, accessories or parts of the body may be injured between the weight blocks, and there is a difficulty in changing the design of the entire exercise equipment. It is not only beautiful but not expensive, but also requires a lot of installation space for use, and noise and noise are generated during operation, making it difficult to concentrate on exercise.

The exercise device 100 using the adiabatic expansion to which the technology of the present invention is applied is a holding means such as a footrest, a fixing hole, a sucker, and the like so that the user can step on and maintain the foot or connect with a wall or floor or a general weight exercise device. An instrument cylinder 102 is provided at the bottom of 101.

One side of the instrument cylinder 102 has a closed surface 103 is blocked, the opposite position of the closed surface 103 is provided in a cylindrical shape having an opening 104, while maintaining sufficient rigidity Use a plastic material that can be seen inside.

The instrument cylinder 102 has a piston 105 that generates tension by the force to expand the air inside the instrument cylinder 102 by returning to its original position by pulling.

The outer diameter of the piston 105 is formed to be smaller than the inner diameter of the instrument cylinder 102 to provide ease of insertion, after forming one or more airtight ring groove 106 on the outer surface of the piston 105, the airtight ring 107 is coupled to maintain the inner wall surface and airtightness of the instrument cylinder 102 so that air between the lower surface of the piston 105 and the instrument cylinder 102 does not flow in and out.

An upper side of the piston 105 is connected to the piston rod 108 to be exposed above the mechanism cylinder 102 to have a grip 109 so that the user can hold it by hand or connect with other exercise equipment.

The opening portion 104 of the instrument cylinder 102 is coupled to the intermittent cap 110 to prevent the piston 105 from leaving the instrument cylinder 102 during the up and down movement, the instrument cylinder, The coupling of the 102 and the intermittent cap 110 may be variously implemented in a form capable of disassembling and coupling such as screw coupling, one-touch coupling, hook using a hook.

When the piston 105 is in close contact with the closing surface 103 of the instrument cylinder 102, the minimum surface gas can be maintained while preventing the piston 105 from being able to pull the piston 105. At the same time leaving the space there is to have a limiting means 111 for limiting the maximum tensile force (force, maximum weight) generated when pulling the piston 105.

The restricting means 111 may be provided through a ring that prevents the piston 105 from coming into close contact with the closing surface 103, and forms a unitary step in the mechanism cylinder 102 or at the lower end of the piston 105. It may be carried out in various ways, such as to form a protrusion.

The piston rod 108 and the grip 109 at the lower end of the piston 105 may be configured in one piece, may be configured by combining in a state of interposing the airtight material so as to separate and prevent air leakage, respectively, In the center thereof, a penetrating air passage 112 is formed to enable external air communication with the outside and the device cylinder 102.

The grip 109 has an opening and closing means 113 to open and close the air passage 112 to open the piston 105 when assembling the mechanism cylinder 102 and to prevent air leakage when performing the movement. do.

The opening and closing means 113 may be configured by a valve body of a conventional technique, or may be configured to be interrupted by screwing through a gastight member on the piston rod 108 and the grip 109.

The piston rod 108 is further provided with a piston adjusting means 115 to adjust the distance between the closed surface 103 of the instrument cylinder 102 and the lower end of the piston 105 to the user's physical condition or movement form, rehabilitation It is possible to freely set the pulling force of the piston 105 in accordance with the state of exercise or physical therapy.

In the present invention, the piston adjusting means 115 is formed with a screw 116 on the outer surface of the piston rod 108, the control disk 117 is screwed to the piston rod 108, and the control disk 117 of Coupled to the upper and lower side is exemplified as consisting of an intermittent nut 118 to continuously maintain the adjusted state.

However, the above example, of course, to form the adjustment groove in the piston rod 108 in multiple stages, the control groove is coupled to the adjustment disk 117 to be adjusted in multiple stages by a stopper consisting of a spring, a stop ball and knob. It will be possible to implement in various forms, such as type, it is preferable to avoid the form of penetrating the piston rod 108 because the air passage 112 is formed around the axis of the piston rod 108.

When the independent exercise is to be performed only by the exercise device 100 using the adiabatic expansion, the holding means 101 is stepped on by the user's foot, or the holding means 101 is fixed to the floor or the wall to stabilize the device cylinder 102. It allows you to maintain state.

In this state, the user grasps the grip 109 and pulls it, which is a movement, in which the piston 105 connected to the grip 109 is in close proximity to the closing surface 103 of the instrument cylinder 102 and then the closing surface 103. In this case, the air that exists between the piston 105 and the closing surface 103 expands without a heat transfer from the outside.

That is, since the inside of the mechanism cylinder 102 is hermetically sealed, the shorter the distance between the piston 105 and the closing surface 103, the stronger the pulling force of the piston 105, the more force is required, and the piston The distance between the 105 and the closing surface 103 may be greater and the pulling force is gradually reduced.

Therefore, the user can adjust the distance between the piston 105 and the closing surface 103 by using the piston adjusting means 115 according to their physical conditions or movement conditions, loosen the intermittent nut 118 and adjust the disc ( The 117 may be moved upward and downward of the piston rod 108.

At this time, when the piston 105 is as close as possible to the closing surface 103, the amount of air is minimized to maximize the force to pull the piston 105, when the piston 105 is far from the closing surface 103, the piston 105 The pulling force gradually decreases, so adjust accordingly.

Of course, when moving the piston 105 it is difficult to move in the state of maintaining the airtight, it is difficult to maintain in the correct position, so at this time open the opening and closing means 113 provided in the grip 109 and the piston rod 108 The air flow 112 is formed in the center of the piston 105 to allow the outside air to flow. After the adjustment is completed, the opening and closing means 113 may be closed to block the outside air flow.

And, if you want to use the exercise device 100 using the adiabatic expansion in connection with a known exercise device, after connecting the holding means 101 and the grip 109 with the exercise device, grab the handle of the exercise device, etc. You can do it as if you are exercising using exercise equipment.

For example, in the case of a pull-down machine for strengthening the back muscles, the exercise device 100 using the adiabatic expansion of the present invention is positioned between the handle and the weight block of the exercise device, and the holding means 101 is in the weight block direction. The grip 109 is located in the direction of the handle of the exercise device, and then connected to the exercise device so that the exercise can be performed in a connected state.

As another example of the present invention, the length of the instrument cylinder 102 may be extended by using the variable means 120, but the screw is attached to the upper outer surface of the instrument cylinder 102 and the lower outer surface of the extension cylinder 121. 122 may be formed, and the length may be extended by engaging with an extension ring 124 having a screw 123 formed in the inner diameter portion thereof.

Of course, it will be natural to interpose the airtight member 125 such as an O-ring to maintain the airtightness between the instrument cylinder 102, the extension cylinder 121 and the extension ring 124.

In another example of the present invention, the pulley means 130 may be provided so as to increase the pulling distance of the grip 109 while reducing the moving distance of the piston 105 without extending the length of the mechanism cylinder 102. Got it.

The pulley means 130 is one fixed lure 131 is fixed to the upper surface of the piston 105, and two fixed to one side or both sides of the bottom surface of the closing cap 110 is coupled to the upper portion of the mechanism cylinder (102). Movable pulley 132 coupled to the long pulley 134 formed on the fixed pulley 132, the pulley guide 133 protruding downward from the bottom of the closing cap 110, and the first and second high precision pulleys (131, 132) It consists of a rope 136 connecting between the pulley 135 and the grip 109.

It will be apparent that the closing cap 110 through which the rope 136 connected to the grip 109 penetrates air tightly so that the air inside the device cylinder 102 does not flow out.

According to the present invention, when the piston coupled to the mechanism cylinder is pulled, the air located in the mechanism cylinder expands by simply pulling the piston by a force to return to its original state while expanding the air, thereby adjusting the amount of air inside the mechanism cylinder. By controlling the pulling force of the piston, the exercise can be performed according to physical conditions, physical therapy or rehabilitation conditions, and it can be used in connection with existing exercise equipment while occupying a small installation space.
