The amplitude variable exercise device 1 according to the present invention was formed (configured) as follows.

The housing 2 is formed in a predetermined shape to protect various devices installed therein, and any one of the front side or the rear side forming the housing 2 is formed in a detachable form and coupled / attached by a mounting means such as a bolt screw. To allow separation.

In the interior of the housing (2), the slide support (5) is placed on the bottom so that it can be moved left and right by the amplitude variable device (10), which will be described later in detail, and a lever (in the center of the top of the slide support (5)) 6) was formed to settle the slide support (5) described later.

An amplitude variable device 10 for moving the slide support 5 to the left and right was formed as follows.

 The nut hole 13 is formed in the lower center of the slide support 5 so as to penetrate right and left, and in the lower center of the housing 2, the support rods 14-1 and 14-2 are provided in the lower center. 11) to the left and right, the screw rod 11 is screwed to the nut hole 13 of the slide support (5), the reduction motor (15) to the screw rod shaft 12 protruding out of the housing (2) ) Is connected to the rotation axis.

In addition, although not specifically shown, the amplitude variable device 10 for moving the slide support 5 to the left and right is equipped with a cylinder operated by hydraulic or pneumatic to the housing 2 to move the slide support 5 forward / backward. And, the slide support (5) can be guided by a conventional LM guide consisting of a guide block (guide hole or guide groove) and the guide rail to move left and right in a straight line.

Rolling plate 16 is placed on the upper side of the lever 6 of the slide support 5 to be rolled left and right based on the lever 6.

On the upper side of one side of the rolling plate 16, a camshaft 21 formed eccentrically on the cam 20 is installed, and a reduction shaft motor having a camshaft 21 protruding outward from the housing 2 is provided outside the housing 2. It was connected to the rotary shaft of (22).

On the other side of the rolling plate 16, the shaft groove 19 is formed to load (load) the shaft rod 19 formed at the lower end of the linear motion rod 18, and the lower side of the distribution hole 3 on the upper surface of the housing 2. The guide tube 25 is fixed in communication with the distribution hole (3) by inserting a linear motion bar (18) to operate up and down.

The operation relationship will be described below.

The variable amplitude exercise apparatus 1 according to the present invention operates as follows when the slide support 5 is positioned on the center line 0 as illustrated in FIG. 2.

When the reduction motor 22 operates, the cam 20 installed by the cam shaft 21 rotates, and when the cam 20 rotates, the rolling plate 16 supported by the lever 6 on the center of the bottom is left, The right is to be rolled up and down, the height (width: h1 = h2) that the left and right ends of the rolling plate 16 is rolled while maintaining the same height.

When the rolling plate 16 rolls up and down left and right, the linear motion rod 18 in which the shaft bar 19 is placed in one shaft groove 17 of the rolling plate 16 is moved up and down by a certain height (h1 = h2). Ascend and descend as.

Therefore, the linear motion bar 18 also rolls the footrest of the exercise device constantly while moving up and down with a constant width.

In the above state, when the reduction motor 15 of the amplitude variable device 10 is operated to rotate the screw rod 11 in the forward direction or the cylinder (not specifically shown) is operated, the slide support (5). Is moved to one side from the center line (0) as illustrated in Figure 3a.

As shown in FIG. 3A, when the reduction motor 22 is operated while the slide support 5 is moved to one side from the center line 0, the cam 20 installed as the cam shaft 21 rotates.

When the cam 20 rotates, the rolling plate 16, which is supported by the center of the bottom surface, is rolled up and down, left and right, and the left end of the rolling plate 16 is the lever 6 of the slide support 5. : Since the distance from the supporting point is short, the height (width: h1) at which the left end is rolled is maintained while maintaining a very low height, while the right end is connected with the lever (6: support point) of the slide support (5). Since the distance is maintained in a relatively long state, the left end rolls while maintaining a relatively high height h2.

Therefore, the linear motion bar 18 also rolls the scaffold of the exercise device in a large width while moving up and down in a large width.

On the other hand, if the reduction motor 15 of the amplitude variable device 10 is operated in reverse to rotate the screw rod 11 in the reverse direction or the cylinder (not specifically shown) is operated in reverse, the slide support 5 As shown in Figure 3b is to move from the center line (0) to the other side.

When the reduction motor 22 operates while the slide support 5 is moved from the center line 0 to the other side as illustrated in FIG. 3B, the cam 20 installed as the cam shaft 21 rotates.

When the cam 20 rotates, the rolling plate 16 supported by the center of the bottom surface is rolled left and right and up and down, and the left end of the rolling plate 16 is the lever 6 of the slide base 5. Since the distance from the supporting point is kept long, the height (width: h1) at which the left end is rolled is kept while maintaining a very high height, while the right end is the lever (6: supporting point of the slide stand 5). Since the distance to the other side is relatively short, the left end is rolling while maintaining the height h2 having a relatively low amplitude.

Therefore, while the linear motion bar 18 also moves up and down with a small width to roll the footrest of the exercise device to a small width.

As described above, the variable amplitude exercise apparatus 1 according to the present invention moves the rolling plate 16 to the center or to the left or the right side as illustrated in FIGS. 2 and 3A and 3B. By converting the supporting position, the upper and lower widths of the rolling plate 16 and the linear motion bar 18 can be changed in various ways, and thus, the width of the foot of the exercise device can be varied in various ways. .

Although described and illustrated only with respect to specific embodiments of the present invention, it will be apparent to those skilled in the art that various modifications and changes can be made within the technical scope of the present invention, and such modifications and modifications belong to the appended claims. It is natural.
