The resistance adjusting device includes a magnetic member 5 installed on the surface of the wheel 1, a disk 31 operably installed on the shaft 2, a concave portion 313 formed on one surface of the disk 31, and a metal fitted into the concave portion 313. A plate 32, a panel 6 installed on the shaft 2, a cable 30 extending through the panel 6 and connected to the disk, and a disk 31
And a spring 7 installed between the panel 6 and the panel. By pulling the cable 30 and adjusting the distance between the metal plate and the magnetic member, the resistance generated on the wheel 1 can be adjusted.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to exercise equipment.

[0002]

[Prior art]

 Conventional exercise equipment using belts and wheels generally has a wheel with radially extending blades on the outside, with a first pulley attached to the hub of the wheel and a second pulley attached to the shaft. There is a belt between them. Because the diameters of the first pulley and the second pulley are different, when the belt is rotated, the wheel rotates and the blade generates air resistance.

[0003]

[Problems to be solved by the invention]

 However, conventional exercise equipment has a constant resistance and cannot be adjusted. Therefore, it cannot meet various needs of users. The exercise device disclosed in Utility Model Patent Publication No. 292569 disclosed in Taiwan partially solves the above-mentioned drawbacks, but since the resistance is controlled by using a torsion spring and many components are required, frequent use is required. Maintenance is required.

Therefore, an object of the present invention is to provide an exercise apparatus having a simple structure capable of easily adjusting the resistance.

[0005]

[Means for Solving the Problems]

 The exercise apparatus according to claim 1 of the present invention includes an exercise device and a resistance adjusting device. The exercise device is mounted on a wheel having a hub having a passage therethrough, a shaft inserted into the passage, a plurality of blades extending radially outward from the wheel, and wound around the hub. Belt. The resistance adjusting device is installed on a magnetic member installed on the surface of the wheel, a disk operably installed on the shaft, a recess formed on one surface of the disk, a metal plate fitted on the recess, and the shaft. Panel, a cable extending through the panel and connected to the disk, and a spring installed between the disk and the panel. By pulling the cable and adjusting the distance between the metal plate and the magnetic member, the resistance generated on the wheel can be adjusted.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the exercise apparatus for exercise equipment according to one embodiment of the present invention includes a hub 10 and a wheel 1 having a passage 11 passing through the hub. Two bearings 25 are connected. Two bearings 25 are connected to the shaft 2 and rotatably inserted into the passage 11. The plurality of blades 12 are formed to extend radially outward from the wheel 1, and the belt 4 is installed by being wound around the hub 10. When the belt is rotated, the wheel 1 is rotated. The resistance adjusting device for an exercise apparatus according to one embodiment of the present invention includes an annular magnetic member 5 fitted into a concave portion on the surface of the wheel 1. A center passage 311 is formed in the disk 31, and the shaft 2 is installed to pass through the center passage 311. The concave portion 313 is formed on one surface of the disk 31, and the metal plate 32 is installed in the concave portion 313 and is connected to the magnetic member 5. The metal plate 32 is formed of aluminum or an aluminum alloy. On the other surface of the disk 31, two guide rods 312 are installed. The panel 6 is connected to the shaft 2 and has two holes 61, and two guide rods 312 are installed through the holes 61. The elbow member 60 is installed on the panel 6, and the cable 30 passes through the elbow member 60 and is connected to the fitting hole 310 of the disk 31. The spring 7 is provided between the disk 31 and the panel 6. As shown in FIG. 3, when the cable 30 is pulled, the distance between the magnetic member 5 and the metal plate 32 changes, the attractive force between the magnetic member 5 and the metal plate 32 is controlled, and As the distance from the metal plate 32 increases, the resistance applied to the wheel 1 decreases.

As shown in FIG. 4, the magnetic member 5 and the metal plate 32 are installed. The magnetic member 5 is connected to the disk 31, and the metal plate 32 is connected to the wheel 1. As shown in FIG. 5, the magnetic member 5 is installed near the blade 12 on the outer periphery of the wheel 1, and an annular groove 313 'for forming the metal plate 32 is formed inside the concave portion. The resistance applied to the wheel 1 changes depending on the distance between the magnetic member 5 and the metal plate 32, and the exercise equipment can satisfy various requirements.
