At this time, the annular bearing is a non-lubricated bearing, characterized in that the material of MC nylon, urethane, carbon and Nylube.

Rotating device for exercise equipment according to the present invention is provided between the support member and the rotating member of the exercise device to enable the rotation of the rotating member, inflow from the outside using an annular bearing made of MC nylon, urethane, carbon and Nylube material There is no fear of corrosion due to foreign matters containing moisture. In particular, there is little risk of accidents caused by corrosion of the bearing, and since it can be used for a long time without lubrication, the life of the exercise equipment can be extended, and there is no problem of contaminating the user's clothes with lubricating oil or the like.

With reference to the accompanying drawings will be described embodiments of the present invention;

1 is a perspective view of an outdoor sports equipment to which the rotary device for a sports equipment according to the present invention is applied.

The exercise device shown in FIG. 1 is a bench press type exercise device among the exercise devices to which the rotary device for exercise device according to the present invention is applied. In this embodiment, the exercise device of the bench press type described above will be described as an example. However, the rotary device for exercise equipment according to the present invention is not necessarily applied only to a bench press type exercise equipment, and can be applied to various exercise apparatuses including a bench press type exercise equipment.

Referring briefly to the above-described bench press type exercise device 100 with reference to Figure 1, the frame 110 is firmly fixed to the ground, the top of the handle is rotatably coupled to the frame 110 120, a connecting rod 130 hinged to the upper end of the handle 120, and a connecting rod 130 hinged to the lower end of the connecting rod 130 and pushing or pulling the handle 120 It is configured to include a seat 140 and the foot 150 is hinged on the frame 110 to be raised or lowered by.

The bench press type exercise apparatus 100 configured as described above is seated by the connecting rod 130 when the user pulls down the handle 120 with both hands while sitting on the seat 140 and raising the foot on the footrest 150. 140) is to lift the upper body exercise, has the same movement effect as a conventional bench press.

On the other hand, in the above-described bench press type exercise equipment 100, the components 110 to 150 are hinged, that is, between the frame 110 and the connecting rod 130 and the handle 120 and the connecting rod Between the 130 is applied to install the rotary device for exercise equipment 200 according to the present invention.

At this time, since the above-described respective rotary devices 200 have the same structure, an exercise device rotating device according to the present invention will be described as an example of the exercise device rotating device 200 provided on the top of the handle 120.

Figure 2 is an enlarged view of the rotary device for exercise equipment according to the present invention, Figure 3 is an exploded perspective view of the rotary device for exercise equipment according to the present invention, Figure 4 is a cross-sectional view of the rotary device for exercise equipment according to the present invention. to be.

As shown in Figures 2 to 4, the exercise device rotary device 200 according to the present invention, the housing 210 is provided on the upper end of the handle, the rotating shaft 220 is coupled through the housing 210 ), An annular bearing 230 provided between the housing 210 and the rotating shaft 220, and a cap 240 coupled to at least one end of the housing 210.

The housing 210 has a cylindrical shape in which a through hole 212 is formed therein so that the rotating shaft 220 may be coupled therethrough. In addition, the through hole 212 has a larger diameter at both ends than the suspension so that the annular bearing 230 can be coupled to both ends thereof, and the cap 240 is coupled to both ends of the through hole 212. A locking groove 214 for coupling with the cap 240 is formed at the inner side of the end.

The rotating shaft 220 is a cylindrical shape having a diameter equal to or slightly smaller than the interruption of the through-hole 212, the fixing groove 222 is formed at both ends thereof, the snap ring 224 is coupled to the fixing groove 222 To prevent the detachment of the annular bearing 230.

The annular bearing 230 is provided between the housing 210 and the rotating shaft 220 as described above, and is a kind of rolling means for rotating the rotating shaft 220, and penetrates in the center so that the rotating shaft 220 can penetrate. It is a disk shape in which the ball 232 is formed. At this time, the annular bearing 230 used in the present embodiment is an oil-free bearing that does not require lubricating oil, such as grease, and is preferably made of MC nylon, urethane, carbon, and Nylube.

Among these, MC nylon (Mono Cast Nylon) material is excellent in mechanical strength, durability, abrasion resistance, thermal properties, fatigue resistance, and the like, in particular excellent in corrosion resistance is very suitable for the manufacture of the annular bearing 230.
