On the other hand, each of the hook members 15a and 15b is selectively fitted to both the first and second chains 24a and 24b of the first and second chain units 20a and 20b when they are pivoted up and down. It has an engagement portion for snapping to form an overall "T" shape (shown best in Figure 3) as described above.

Now, a more detailed description will be made of the first and second chain units 20a, 20b of the present embodiment mentioned above, and these first and second chain units 20a, 20b are mutually as shown in the figure. It is arranged side by side.

The first chain unit 20a includes a first main sprocket 22a rotatably mounted to the frame 2 and a corresponding first idle sprocket 23a and the sprockets 22a and 23a. The first chain 24a and the first main gear 26a are integrally rotated with the first main sprocket 22a.

Similarly, the second chain unit 20b includes a second main sprocket 22b rotatably mounted to the frame 2 and a corresponding second idle sprocket 23b and the sprockets 22b and 23b. A second chain 24b that extends and a second main gear 26b that rotates integrally with the second main sprocket 22b are included.

At this time, as shown in the figure, the first main gear sprocket 22a and the second main gear sprocket 22b, and the first main gear 26a and the second main gear 26b are disposed adjacent to each other. The resistance and restoring force of the resistance generating unit 30 to be described below is directly involved in the generation.

Now, a detailed description of the resistance generating unit 30, which is connected to the first and second chain units 20a and 20b, provides a resistance against movement of the driving units 10a and 10b described above and a corresponding restoring force. This will be done.

In the present embodiment, the resistance generating unit 30 is a pinion 32 which is commonly engaged with the first and second main gears 26a and 26b, and a pin that is engaged with the pinion 32 so as to be reciprocated from side to side. A size gear 34 and a tension and compression spring type spring member 36 having one end connected to the rack gear 34 and the other end fixed to the inner wall of the frame 2.

Accordingly, when the first and second main gears 26a and 26b rotate the pinion 32 simultaneously, the pinion 32 causes the rack gear 34 to reciprocate selectively left and right. The reciprocating motion of the rack gear 34 selectively stretches or compresses the spring member 36 connected thereto, which is in response to the user's movement of opening or narrowing the first and second drive units 10a and 10b. Resistance and elastic resilience against this resistance are generated.

At this time, although not shown in the above description and drawings, the resistance generating unit 30 is further added to the pneumatic cylinder for generating a resistance by the air pressure can be used for the double the resistance and the selective adjustment of the resistance Of course, this will be apparent to those skilled in the art, and the specific description thereof has been omitted in the present specification because it is less relevant to the spirit of the present invention.

Now, with reference to FIGS. 1, 4, 5 and 6, a detailed description will be made of the operation of the exercise device 1 described above.

Referring to FIG. 1, when the user opens the first and second drive units 10a and 10b in the x direction with respect to each other, the first hook member 15a and the second engaged member on the upper portion of the first chain 24a are provided. The second hook member 15b engaged with the lower part of the chain 24b counterclockwise the first and second main sprockets 22a and 22b and the first and second main gears 26a and 26b integrated therewith. It can be seen that the rotation.

At this time, since the first and second main gears 26a and 26b rotate together in the counterclockwise direction, the pinion 32 which is commonly engaged with these main gears 26a and 26b is clockwise as shown in FIG. Will be rotated.

Accordingly, the pinion 32 linearly moves the rack gear 34 engaged with the pinion 32 in the direction A of FIG. 1 to extend the spring member 36 connected to the rack gear 34.

As a result, it can be seen from the foregoing description that the elongation of the spring member 36 generates a resistance force, which is ultimately generated by the user opening the first and second drive units 10a and 10b relative to each other. .

At this time, the spring member 36 has an elastic restoring force in a direction opposite to the A direction, which means that much less force is consumed when the user narrows each other than when opening the drive units 10a, 10b. do.
