Next, as shown in FIGS. 8 and 9, in order to move the elevating table 15 up and down and fix it at a desired height position, the knob bolt 19 is loosened and released from the locking small hole 18, and the projecting pin 18 is released. 20 supporting pillars 1
The lift table 15 may be moved up and down in a state in which the lift table 15 is separated from the locking small hole 18. In this case, if the elevating table 15 is moved up and down with the tip 52 of the projecting pin 20 in contact with the surface of the support column 1, the spring 53 of the spring 53 is reached when the projecting pin 20 reaches the position of the locking small hole 18. Due to the restoring force, it automatically projects into the small hole 18.
Denoted at 54 are rollers attached inside the lift 15. When the elevating table 15 is lowered in the direction of arrow A, the long spring members 13 and 13 are extended and the tension thereof is increased, and the tilt angle θ of the rocking pieces 12 and 12 (when the elevating table 15 is at the highest position). 0) is also large. As shown by the phantom line in FIG. 9, when the lifting platform 15 reaches the position near the lowest position, the inclination angle θ approaches 90 degrees, and at this time, the swinging pieces 12, 12 of the tension of the long spring member 13 are rotated. The component force related to the moment M to be caused is extremely small. As shown by the phantom line in FIG. 9, when the lifting platform 15 is at the highest position, the long spring member 13 is close to the natural length,
And it will be in a tilted state. Moreover, one end of the long spring member 13 is located higher than the upper end of the top frame 11.

As shown in FIG. 10, when the butterfly lever 16 is used, the vertical swing lever 17 is retracted upward. That is, the shaft that pivotally supports the swing lever 17
It suffices to insert the support pin 55 into the short tubular portion 62 provided on the side opposite to the side of the 26, and to hold a part of the arm joint 27 on this. In this way, the pin 55 can be inserted into and removed from the short tube portion 62. By retracting the rocking lever 17 in this manner, the vertical axis Y, around the vertical axis Y, and around the vertical axis Y, respectively.
It can swing over 180 degrees. The elastic members 30 are commonly used for the butterfly lever 16 and the vertical swing lever 17, and insertion holes 56, 56 are provided at both ends. In the embodiment, the insertion holes 56, 56 are formed in the rubber main body 57. It is formed by small ring bodies 58, 58 that are integrally fixed. (See Figure 14). By inserting the elevators 15 and the locking protrusions 28 and 29 of the butterfly levers 16 and 16 into the insertion holes 56 and 56, a constant resistance force can be obtained when the butterfly levers 16 and 16 swing. The resistance can be increased / decreased by increasing / decreasing the number of elastic members 30. However, as shown in FIG. 11, it is also possible to attach the mounting member 31 in the front-rear direction. The attachment member 31 can be easily attached to the elevating table 15, and the engagement small holes of the attachment member 31 and the engagement member 49 can be provided.
It suffices to insert the locking pin 55 from below in a skewered manner into 56, 60 ..., and since the locking small pin 61 that is elastically projected is attached to the tip of the locking pin 50, the mounting member 31 Does not leave during use.

Next, as shown in FIG. 12, in order to use the up-and-down swing lever 17, the butterfly levers 16 and 16 may be retracted to the rear side of the lift table 15, and then the above-mentioned The push-down projection 33 and the locking projection 34 are connected by the elastic member 30 ...

FIG. 13 shows that the push-up protrusion 32 and the locking protrusion 34 are connected by the elastic member 30.

As shown in FIG. 15, by removing the bench support 7, the bench 9 can be brought into an inclined state in which the tip portion is lowered. This is suitable for abdominal muscle exercise.

Explaining the training method using the butterfly levers 16 and 16, as shown by the phantom line in FIG. 1,
The practitioner T sitting on the bench 9 attaches his arm to the outside of the butterfly levers 16, 16 which are open to the left and right, and grips 23,
Hold 23 Thereafter, the arms 16 are swung to close the levers 16 and 16 in front of the face, and the levers 16 and 16 are returned to their original positions.

Next, a training method performed using the vertical swing levers 17, 17 will be described. As shown in FIG. 16, a trainee T who sits down on the bench 9 grips the grips 25, 25 of the levers 17. First, squeeze on both sides of the neck, then push it straight up and then return it to its original position. FIG. 17 shows a case where the elastic member 30 is replaced and the trainee T pushes down the lever 17 in substantially the same manner as in FIG. Although not shown, various other operations can be performed by using the swing lever 17 or the butterfly levers 16 and 16. Further, the operation is performed even when the bench 9 is tilted or the bench 9 is removed. obtain.

As described above, in order to move the elevating table 15 up and down, the swing members 12, 12 pivotally supported by the top frame 11 support the spring members 13, 13, and the lower ends of the spring members 13, 13 are moved up and down. By connecting the bases 15, the load of the lifting base 15 at the time of vertical movement can be reduced, and vertical movement can be performed quickly, easily and smoothly. When the lifting platform 15 is in the raised position, the long spring member 13 is in a considerably inclined posture, and the two types of spring members 13 and 14 are interlockingly connected by the swing piece 12, and the upper end of the long spring member 13 is connected. Since the tip ends of the rocking pieces 12, 12 that pivotally connect the upper part of the top frame 11 are located higher than the upper end of the top frame 11, the vertical moving distance of the lifting platform 15 is increased, and thus the height of the support column 1 is reduced. You get it (see Figure 9).

Since the protruding pin 20 having the spring 53 built therein is used to position the lifting table 15, it is not necessary to search for the small holes 18 of the support pillar 1, and the position is automatically determined only by moving the lifting table 15 up and down. Therefore, after that, the knob bolt 19 can be rotated by hand to securely fix it.

If one of the butterfly levers 16 and 16 and the vertical swing lever 17 is in the retracted state, there is no problem in using the other, and therefore neither of them is required to be removed. In particular, to retract the butterfly levers 16,16, the vertical axis Y, Y
It is extremely easy because it only needs to be swung around. Also,
When the swing lever 17 is retracted, the support pin 55 may be simply engaged with and disengaged from the short tube portion 62.

Since it does not need to be removed, there is no need for an extra space for temporarily placing the removal tool, and there is no risk of loss.

Since the vertical swing lever 17 is pivotally supported on the lift 15 via the arm joint 27 having the fan-shaped portion 44, the vertical position can be changed only by engaging / disengaging the angle changing pin 47.

The mounting member 31 having the locking protrusions 28, 28 can be fixed to the locking member 49 with their front and back being opposite to each other, and further, mounting and dismounting can be performed by engaging and disengaging the locking pin 50. be able to. Therefore, the distance between the locking protrusions 28 and 29 can be changed to easily adjust the exercise load when the butterfly lever 16 is used.

The angle of the bench 9 can be easily changed only by pulling out the shaft 64 (see FIG. 3).
