Description

Flywheel fitness system

The invention is related to sports equipment, in particular to a flywheel fitness system that uses flywheel weight 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 shaft center where the flywheel is placed must have a free end for replacing the flywheel. However, the weight of the flywheel can easily cause the free end of the shaft to skew, causing the shaft When the center rotates, it rotates eccentrically, causing noise or component wear. The current methods to solve this problem generally use multiple shaft sleeves of different sizes or increase the accuracy between the shaft center and the shaft sleeve to improve the shaft skew problem, but the cost of using this method is higher.

In addition, the flywheel will rotate at a high speed during operation of the flywheel fitness system. At this time, the free end of the flywheel is exposed, which may cause safety problems when it comes into contact with the human body.

In order to solve the above 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 of the flywheel axis and to cover the axis, to solve the problem of eccentricity of the axis due to the weight of the flywheel, and Improve the safety of use.

Based on the above objective, the present invention provides a flywheel fitness system, including a body, one side of the body has an accommodating portion for accommodating at least one load-bearing element, and an axis is disposed in the body and partially protruding from the accommodating portion At least one load-bearing element has a shaft hole and is sleeved on the shaft center, a central 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, The supporting force of the shaft center is provided so that the shaft center will not rotate eccentrically due to the weight of the load-bearing element, wherein the load-bearing element is a flywheel.

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

Preferably, the accommodating portion is a groove, the side wall of the cover has an engagement structure, the engagement structure is a plurality of positioning latches, the side wall of the groove has a plurality of positioning grooves, and the positioning latches are configured Lean against the positioning grooves to complete the positioning of the cover.

Preferably, the connecting structure is a plurality of positioning grooves, the side wall 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 implementation, structure, and achieved effects of the present invention, the accompanying drawings are described as follows:

Please refer to Figures 1 and 2, which illustrate a flywheel fitness system, including a body 10, a side surface of the body 10 has an accommodating portion 13 for accommodating at least one load-bearing element 18, and an axis 11 is disposed in the body 10 And partly protruding from the accommodating portion 13, the at least one load-bearing element 18 has a shaft hole, and the load-bearing element 18 is sleeved on the protruding end (that is, the free end) of the shaft 11 and is arranged in the accommodating portion 13 , The center of the inner surface of a cover 20 has a positioning portion 21, a sleeve 22 is disposed on the positioning portion 21, and the positioning portion 21 is clamped to the free end of the shaft 11, the sleeve 22 and the shaft 11 is tightly fitted, so that the cover body 20 provides the supporting force of the shaft 11 and avoids the problem of eccentric rotation of the shaft 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 training needs of the user.

In this embodiment, the accommodating portion 13 is a groove, the cover 20 and the groove 13 are approximately circular, and the cross-sectional profile of the cover 20 is slightly smaller than that of the groove 13 The side wall of the cover body 20 has a joint structure, the joint structure is a plurality of spaced positioning tenons 23, the groove wall of the groove 13 has a plurality of positioning grooves 15, when installing the positioning tenons 23 is correspondingly arranged in the positioning grooves 15, and the positioning portion 21 of the cover 20 is engaged with the free end of the shaft 11, so that the cover 20 can be positioned on the body 10 and close the groove 13, wherein The shaft 11 may be a rotating latch. After the cover 20 is installed, the user will not directly touch the high-speed rotating latch during training to cause injury, which improves 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 against the The positioning groove 31 is used to complete positioning the cover 20.
