Description

Noise reduction exercise equipment < RTI ID = 0.0 >

The present invention relates to a noise reduction exercise device. More particularly, the present invention relates to an adductor muscle and a sphincter muscle strengthening exerciser that a user can easily adjust to exercise intensity. A guide roller having an acetal resin layer formed between a sliding footrest and a guide rod is configured to prevent wear of the guide rod, To a noise reduction type exercise machine capable of reducing noise generated when a sliding footrest moves.

Generally, in order to exercise the adductor muscles and sphincter muscles, it provides both linear movement that slides the foot plate to both sides and rotational movement that rotates the foot plate, so that the user can perform the torsion rotation in the course of raising the leg during exercise, And sphincter muscles that can simultaneously exercise the sphincter and sphincter complex has been developed and used.

For example, in Korean Patent No. 10-1162335, Korean Patent No. 10-1311947, and Korean Patent No. 10-1323261, there is proposed a method of controlling a linear motion in which a foot plate is slid to the left and a rotational motion in which a foot plate is rotated In addition, it has been shown that an adductor muscle and a sphincter strengthening exercise device which can simultaneously exercise an adductor muscle and a sphincter muscle by making it possible for a user to exercise at the same time,

However, the prior art documents do not have a means for adjusting the tension of the spring to adjust the intensity of the exercise, so that it is impossible for the user to adjust the intensity of exercise according to the physical condition.

In addition, in the case of the conventional adductor muscle and sphincter muscle strengthening exerciser, since the contact surfaces between the components such as the shaft for rotating the footrest and the support frame in contact with the shaft are all made of a metal material, There is a problem that the user is inconvenienced by noise as noise is generated.

Therefore, since a separate axial heat treatment process must be performed to reduce the metallic contact noise, the manufacturing cost of the exercise apparatus is increased.

On the other hand, due to frequent friction of the mutual contact surfaces of the metal materials, abrasion of the shafts occurs and malfunctions are caused. Therefore, it is difficult to use the exercise equipment for a long time and also maintenance cost due to frequent maintenance is separately required. Improvement of sphincter strengthening exercise equipment is indispensable.
