Fig. 7 is a view showing a fitness device using the thermal expansion applied to the technique of the present invention Other configurations will be described together with the configuration diagrams.

The exercise device 100 using the thermal expansion applied with the technique of the present invention is provided with a holding means such as a footrest, a fixing hole, a suction plate, or the like so as to be able to be stepped on or held by a user using a foot, or connected to a wall surface, (101), and a mechanism cylinder (102) at the lower end.

One side of the mechanism cylinder 102 has a closure surface 103 that is clogged and the opposite side of the closure surface 103 has a cylindrical shape with an opening 104 so that sufficient rigidity can be maintained Use plastic material to check inside.

Inside the mechanism cylinder 102, a piston 105 for expanding the air inside the mechanism cylinder 102 by pulling and generating a tensile force by a force for returning to the original position is built in.

The outer diameter of the piston 105 is formed to be smaller than the inner diameter of the mechanism cylinder 102 so as to provide ease of insertion and one or more inner milling grooves 106 are formed on the outer surface of the piston 105, (107) so as to maintain airtightness with the inner wall surface of the mechanism cylinder (102) so as to prevent air from flowing between the lower end surface of the piston (105) and the mechanism cylinder (102).

A piston rod 108 is connected to the upper side of the piston 105 to expose the upper side of the mechanism cylinder 102, and a grip 109 is provided so that a user can hold the same by hand or connect with other exercise devices.

The intermittent cap 110 is coupled to the opening 104 of the mechanism cylinder 102 so as to prevent the piston 105 from moving out of the mechanism cylinder 102 during the upward and downward movements, The coupling between the cap 102 and the intermittent cap 110 may be variously performed in a form capable of disassembling and coupling such as screw coupling, one-touch coupling, and hook coupling.

The piston 105 can be maintained in a vacuum state while the piston 105 is in close contact with the closing surface 103 to prevent the piston 105 from being pulled to the closed surface 103 of the mechanism cylinder 102, (Force, maximum weight) that occurs when the piston 105 is pulled while simultaneously holding the space therebetween.

The limiting means 111 may be provided with a ring that prevents the piston 105 from coming into close contact with the closing surface 103 or may have a configuration in which a unitary step is formed in the mechanism cylinder 102, A shape in which a protrusion is formed, and the like.

The piston rod 108 and the grip 109 may be integrally formed at the lower end of the piston 105. Alternatively, the piston rod 108 and the grip 109 may be combined with each other with an airtight member interposed therebetween so as to prevent air leakage. At the center of these, an air passage 112 is formed so as to enable external communication with the outside of the mechanism cylinder 102.

The grip 109 is further provided with opening and closing means 113 for opening and closing the air passage 112 to open the piston 105 to the mechanism cylinder 102 and to prevent air leakage when performing the movement. do.

The opening / closing means 113 may be constituted by a valve body of a conventional technique, or may be constituted by a shape in which the piston rod 108 and the grip 109 are interlocked with each other through a hermetic seal by screwing.

The piston rod 108 is further provided with a piston adjusting means 115 to adjust the gap between the closing surface 103 of the mechanism cylinder 102 and the lower end of the piston 105 to adjust the physical condition or motion pattern of the user, So that the force for pulling the piston 105 can be freely set in accordance with the state of exercise or physical therapy.

The piston adjusting means 115 is provided in the present invention with a screw 116 formed on the outer surface of the piston rod 108 and an adjusting disc 117 screwed to the piston rod 108, And an intermittent nut 118 coupled to the upper and lower sides to continuously maintain the adjusted state.

However, in the above-mentioned example, the adjustment groove is formed in the piston rod 108 at a plurality of stages, and the adjustment groove is connected to the adjustment disc 117 so as to be adjusted to a multi-stage by a stopper composed of a spring, a stop ball, It is preferable that the air passage 112 is formed at the center of the axis of the piston rod 108 so that the shape of the piston rod 108 passing through the piston rod 108 is avoided.

The state of use of the exercise device 100 using the thermal expansion applied with the technique of the present invention will be described as follows.

In order to carry out the independent exercise with only the exercise apparatus 100 using the single thermal 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 surface so that the apparatus cylinder 102 is stabilized So that the state can be maintained.

In this state, the user grasps the grip 109 and moves when it is pulled, because the piston 105 connected to the grip 109 is close to the closing surface 103 of the device cylinder 102 and then the closing surface 103 is closed, At this time, the air existing between the piston 105 and the closing surface 103 expands without external heat.

That is, since the inside of the mechanism cylinder 102 is in an air-tight state, the shorter the distance between the piston 105 and the closing surface 103 becomes, the stronger the force for pulling the piston 105 becomes, The distance between the closing surface 105 and the closing surface 103 is gradually increased so that the logo pulling force gradually decreases.

Therefore, the user can adjust the distance between the piston 105 and the closing surface 103 by using the piston adjusting means 115 in accordance with his or her physical condition or the exercise condition. 117 may be moved upward and downward of the piston rod 108.

At this time, if the piston 105 is brought close to the closing surface 103 as much as possible, the amount of air is minimized to maximize the pulling force of the piston 105. When the piston 105 moves away from the closing surface 103, The pulling force is gradually reduced, so adjust it accordingly.

When the piston 105 is moved, it is difficult to move the piston 105 while keeping the airtightness. It is difficult to maintain the airtightness at the correct position. In this case, the opening / closing means 113 provided in the grip 109 is opened, The external air can be circulated through the air passage 112 formed at the center of the shaft of the piston 105. After the adjustment is completed, the opening and closing means 113 may be closed to block the flow of external air.

When the exercise device 100 using the thermal expansion is to be used in connection with a well-known exercise device, the holding device 101 and the grip 109 are connected to the exercise device, and then the handle of the exercise device is held You can do it just like you exercise with exercise equipment.

For example, in the case of a rat pulldown machine for strengthening the back muscles, the exercise device 100 using the thermal expansion of the present invention is positioned between the knob of the exercise device and the weight block, And the grip 109 is positioned in the handle direction of the exercise device and then connected to the exercise device.

As another example of the present invention, the length of the mechanism cylinder 102 may be extended by using the variable means 120. In this case, the upper end surface of the mechanism cylinder 102 and the lower end outer surface of the extension cylinder 121 are screwed It is also possible to form the inner ring portion 122 and connect the inner ring portion with the extension ring 124 formed with the screw 123 to extend the length.

Of course, it is a matter of course that a gas tight material 125 such as an O-ring is interposed between the mechanism cylinder 102 and the extension cylinder 121 and the extension ring 124 so as to maintain the airtightness.

As another example of the present invention, even if the pulley means 130 is provided so that the distance by which the piston 105 moves and the distance by which the grip 109 is pulled can be increased without extending the length of the mechanism cylinder 102 Is it.

The pulley 130 includes a fixed drum 131 fixedly mounted on the upper surface of the piston 105 and a fixed drum 131 fixedly installed on one side or both sides of the bottom surface of the drum 110 coupled to the upper portion of the drum 102. [ A movable drum 135 coupled to a slot 134 formed in a drill guide 133 protruding downward from a bottom surface of the finishing cap 110; And a rope 136 connecting between the pulley 135 and the grips 109. [

It is a matter of course that air tightness is ensured in the finishing cap 110 through which the rope 136 connected to the grip 109 penetrates to prevent the air inside the mechanism cylinder 102 from flowing out.

In the present invention as described above, when the piston coupled to the instrument cylinder is pulled, the muscle located in the instrument cylinder is expanded and the muscular strength can be exerted only by pulling the piston by the force of returning to the original state. So that the exercise can be performed according to physical conditions, physical therapy or rehabilitation treatment conditions, and it is possible to use the exercise device in connection with a conventional exercise device while occupying a small space for installation.
