As unexplained reference numeral 12 indicates an interlocking link for rotating the support operating tool 20 up and down in accordance with the movement of the exercise handle.

Hereinafter, the operation and operation of the present invention will be described.

First, the exerciser will exercise while adjusting the weight load of the entire weight 30 according to his ability.

In particular, the weight load of the weight 30 is to be exercised while simply adjusting by rotating the cam shaft 51 by the adjustment dial 80.

That is, when the weight 30 is composed of a total of four 5kg, 10kg, 15kg two, 5kg (1 step), 10kg (2 steps), 15kg (3 steps), 15 by the rotation operation of the camshaft 51 +5 kg (4 steps), 15 + 10 kg (5 steps), 15 + 15 kg (6 steps), 15 + 15 + 5 kg (7 steps), 15 + 15 + 10 kg (8 steps), 15 + 15 + 10 + 5 kg By selectively combining (9 steps), the weight weight load is adjusted in 9 steps.

This will be described in more detail.

When the cam shaft 51 is rotated by the adjusting dial 80, the actuating disk 55 axially mounted on the cam shaft 51 rotates together to act on the cam of the cam protrusion 55a formed on the circumference of the actuating disk. By controlling the connection clamp 40 of each weight 30 by the support operating mechanism 20 to adjust the weight of the entire weight 30 is supported on the support operating mechanism 20.

That is, in the case of the first step, only the 5kg weight 30 is supported by the connection clamp 40 to the support operating tool 20 and the remaining three weights 30 are separated from the support operating tool 20 so that the entire weight The weight load of the 30 is adjusted to 5 kg, and in the case of the second step, only the 10 kg weight 30 is connected and supported by the support clamp 20 by the connection clamp 40 and the remaining three weights 30 are Separated from the support operating port 20 to adjust the weight load of the entire weight 30 to 10kg, in the case of the third step, only the 5kg weight 30 and 10kg weight 30 is supported by the connection clamp 40 It is connected to the support 20 and the other two weights 30 are separated from the support 20 to adjust the weight load of the entire weight 30 to 15kg, 4,5,6,7,8 Step 9 is to adjust the overall weight weight load in the same manner.

At this time, the process of separating the connection clamp 40 of each weight 30 from the support operating port 20 by the cam operation by the cam projection (55a) of the operation disk 55 in more detail, the cam The cam roller 46 at the lower end of the operating link 45 of the connecting clamp 40 is guided to the protrusion 55a so that the operating link 45 rotates about the hinge shaft 47 while the cam is operated. 41 and 41 'are rotated to face each other about the hinge shaft 42 so as to be opened to each other, so that the engaging ends 41a of the upper left and right support links are supported by the support step 22 of the support operating tool 20. It is to be released to separate the weight 30 from the support operating mechanism 20.

On the contrary, when the cam roller 46 at the lower end of the operation link 45 of the coupling clamp 40 is positioned off the cam protrusion 55a, the operation link 45 and the left and right support links 41 and 41 ' While returning to its original position by the spring 43 between the left and right support links, the locking end 41a of the upper left and right links is supported by the support step 22 of the support operating tool 20 again to support the weight 30. Will be supported).

In addition, the process of separating the connection clamp 40 of each weight 30 from the support operating port 20 by the cam operation by the cam projection (55a) of the operation disk 55 as shown in FIG. This is because the cam roller 48b at the bottom of the operation link 48 of the connection clamp 40 is guided in close contact with the cam protrusion 55a so that the operation link 48 is hinged by the cam operation. The locking end 48a at the upper end of the operation link is released from the support step 22 of the support operation tool 20 while rotating about the weight, thereby separating and operating the weight 30 from the support operation tool 20.

On the contrary, when the cam roller 48b at the lower end of the actuating link 48 of the coupling clamp 40 is positioned out of the cam protrusion 55a, the actuating link 48 is rotated back to its original position by the spring 43. The locking end 48a at the upper end of the operation link is supported by the support step 22 of the support operation tool 20 to support the weight 30 to the support operation 20.

As described above, the present invention provides a weight weight by lifting or lowering the exercise knob while simply adjusting the weight load of the entire weight 30 supported by the support operating tool 20 by the rotation method of the adjustment dial 80. It is to exercise according to the load.

In particular, the total weight weight load can be adjusted by weighting the weight weight load of several steps (9 steps) more than the number of weights by combining a small number of weights (four), so that the use efficiency is excellent.

In addition, the present invention is to prevent the safety accident by the weight lock means 60 that the weight 30 supported by the support operating tool 20 is separated during the weight movement.

That is, in the lowering position (the state before the movement) of the support operation tool 20, the locking operation tool 63 connected to the end of the support operation tool by the wire 65 is shot up by the spring 62, but the guide pin 63a is applied. Because the lifting pin 63b at the lower end of the locking mechanism is spaced apart from the locking groove 56a of the locking disk 56 while being moved up and down along the guide groove 67, the cam shaft 51 can be rotated. It is possible to adjust the weight load.

On the contrary, in the support operation tool 20 rising position (movement state), the locking operation tool 63 connected to the end of the support operation tool by the wire 65 is lowered while compressing the spring 62, but not to the guide pin 63a. By lowering elastically along the guide groove (67) by the locking pin (63b) of the lower end of the locking mechanism is inserted into the locking groove (56a) of the locking disk 56 to limit the rotation of the camshaft during movement weight weight load It is impossible to control the and will be safe.

In addition, since the shock absorbing member 70 is installed at the lowered position after the weight 30 is raised and lowered to absorb the impact shock of the weight, safety is further secured.

In addition, the present invention may be directly coupled to the end of the cam shaft 51 by adjusting the rotation dial 80 to adjust the cam shaft 51 directly to adjust the cam shaft, as shown in Figures 16 and 17 the exerciser bench The cam shaft 51 can be rotated by installing the adjustment dial 80 at a position close to the movement position of the seat, which is controlled by the adjustment dial 80 forward and reverse rotation. The two ends of the wires 83 and 83 'are connected to the disks 82 and 52 that are axially mounted to the 51 to rotate the control dial shaft 81 forward and reverse by the adjustment dial. By selectively winding the 83 ', the cam shaft 51 can be easily rotated at a long distance.

In addition, the movement handle 10 and the rotating shaft 11 is assembled to the disc 12, 12 'buttted as shown in Figs. 18 and 19, the circle of the disc 12, 12' Since the plurality of adjusting holes 13 are formed to face at equal intervals on the column, the adjusting bolts 13 are aligned with the adjusting holes 13 while the assembly position of the movement handle 10 and the rotating shaft 11 is rotated up and down, and the fastening bolt 14 By inserting and assembling) to select and adjust the movement start position or the movement direction of the exercise handle 10 (the movement of lifting the movement handle upwards or the movement of the movement handle downwards) to implement various deformation effects.
