In addition, the present invention provides a flywheel fitness system that uses the weight of the flywheel to exercise the muscular tissue of the human body.

Description

flywheel fitness system

The invention relates to sports equipment, in particular to a flywheel fitness system which utilizes the weight of the flywheel to exercise body muscle tissue.

The conventional flywheel fitness system will place flywheels of different weights according to the user's needs. Therefore, the flywheel axis on which the flywheel is placed must have a free end for replacing the flywheel. When the center rotates, it rotates eccentrically, causing noise or component wear. The current methods to solve this problem generally use a plurality of bushings of different sizes or a method of increasing the precision between the shaft and the bushing to improve the problem of the skew of the shaft, but the cost of using this method is relatively high.

In addition, when the flywheel fitness system is operating, the flywheel will rotate at a high speed. At this time, the free end of the flywheel is exposed, which may contact the human body and cause safety problems.

In order to solve the above-mentioned deficiencies, the purpose of the present invention is to provide a flywheel fitness system, especially a structural design with a cover to provide the support force of the flywheel shaft and cover the shaft, so as to solve the problem of eccentricity of the shaft due to the weight of the flywheel, and Improve the safety of use.

Based on the above purpose, the present invention provides a flywheel fitness system, which includes a body, a side surface of the body has an accommodating portion to accommodate at least one load-bearing element, and an axis is disposed in the body and partially protrudes from the accommodating portion , at least one load-bearing element has a shaft hole and is sleeved on the shaft center, a center position of the inner surface of a cover body has a positioning part, the positioning part is provided with a shaft sleeve and the cover body is clamped to the free end of the shaft center, In order to provide the shaft center supporting force, the shaft center will not be eccentrically rotated due to the weight of the load-bearing element, wherein the load-bearing element is a flywheel.

Wherein, the cross-sectional contour of the cover body is smaller than the cross-sectional contour of the accommodating portion, so that the cover body can be positioned on the body and close the accommodating portion.

Preferably, the accommodating portion is a groove, the side wall of the cover has a joint structure, the joint structure is a plurality of positioning tenons, the side wall of the groove has a plurality of positioning grooves, and the positioning tenons are arranged. Abut the positioning grooves to complete the positioning of the cover body.

Preferably, the engaging structure is a plurality of positioning grooves, the sidewall of the groove has a plurality of positioning tenons, and the positioning tenons are configured to abut against the positioning grooves to complete the positioning of the cover body.

In order to clearly illustrate the specific embodiments, structures and effects of the present invention, the following descriptions are given in conjunction with the drawings:

Please refer to FIG. 1 and FIG. 2 , which illustrate a flywheel fitness system, including a main body 10 , a side surface of the main body 10 has an accommodating portion 13 for accommodating at least one load-bearing element 18 , and an axis 11 is disposed in the main body 10 And part of it protrudes out of the accommodating part 13 , the at least one load-bearing element 18 has a shaft hole, the load-bearing element 18 is sleeved on the protruding end (ie the free end) of the shaft center 11 and is arranged in the accommodating part 13 , a cover body 20 has a positioning portion 21 at the center of the inner surface, a shaft sleeve 22 is arranged on the positioning portion 21, and the positioning portion 21 is engaged with the free end of the shaft 11, the shaft sleeve 22 and the shaft 11 is tightly fitted, so that the cover body 20 can provide the support force of the shaft center 11 to avoid the problem of eccentric rotation of the shaft center 11 due to the weight of the load-bearing element 18 . The load-bearing element 18 is a flywheel, and the user can set different weights and/or numbers of flywheels in the accommodating portion 13 according to their own needs to meet the user's training needs.

In this embodiment, the accommodating portion 13 is a groove, the cover body 20 and the groove 13 are substantially circular, and the cross-sectional contour of the cover body 20 is slightly smaller than the cross-section of the groove 13 . Surface profile, the side wall of the cover body 20 has a joint structure, the joint structure is a plurality of positioning tenons 23 arranged at intervals, the groove wall of the groove 13 has a plurality of positioning grooves 15, and these positioning tenons are installed during installation. 23 is correspondingly arranged in the positioning grooves 15, and the positioning portion 21 of the cover body 20 is engaged with the free end of the shaft center 11, so that the cover body 20 can be positioned on the main body 10 and close the groove 13, wherein The shaft 11 may be a rotating tenon. After the cover body 20 is installed, the user will not directly contact the high-speed rotating tenon during training and cause injury, thereby improving the safety of use.

Please refer to FIG. 3 for another embodiment of the present invention, the connecting structure is a plurality of positioning grooves 31 , the side wall of the accommodating portion 13 has a plurality of positioning tenons 32 , and the positioning tenons 32 are arranged to abut against the positioning tenons 32 during installation. The positioning groove 31 is used to complete the positioning of the cover body 20 .
