Swing fitness machine

The present invention relates to an exercise device, and more particularly to an innovative structural type revealer of a swing exercise machine.

According to the work style, office workers often have to sit for a long time. Some people are even busy. In addition to pouring water and going to the toilet, the buttocks almost never leave their seats. If you sit for a long time, if you sit in a bad position, It is easy to backache and back pain, but it causes pelvic displacement, scoliosis, and even cases of injury to the intervertebral disc.

In order to alleviate the above-mentioned discomfort caused by long-term bad sitting posture, there are fitness equipment manufacturers who have launched various types of hip fitness structures. The main structure is nothing more than a support base and a bottom end universally pivoted to the support. a support rod of the seat, a mounting seat fixed to the top end of the support rod, a spring disposed on the support rod, and a seat cushion mounted on the mounting seat, wherein the two ends of the spring are respectively abutted against the The top surface of the support base and the bottom surface of the mount.

However, this conventional structural type has found in the actual use experience that the following problem still exists: the swinging end of the support rod of the conventional hip fitness structure is disposed below, so that when the mount swings relative to the support seat At this time, the spring is only deformed by about a quarter of the length of the lower half, and thereby provides a restoring force, so the force of the entire spring will be concentrated in the lower half, resulting in uneven force, which seriously affects its service life. Furthermore, the support rod is a rigid single member, and the mount is fixed to the top end of the support rod. Therefore, the relative position (angle) between the mount and the support rod is constant, so that the installation is performed. The swinging trajectory of the seat relative to the support base is a fixed hemispherical surface with the radius of the rod center centered on the swinging center of the support rod, which limits the tilting relationship between the mounting seat and the support base.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, is expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

The main purpose of this creation is to provide a kind of exercise machine, and the technical problem to be solved is to make an innovative breakthrough in how to develop a new type of swing fitness device with more ideal and practicality.

The technical feature of the present invention is mainly that the swinging exercise device comprises a connecting device; a supporting seat installed at the bottom end of the connecting device, the supporting seat is arranged on a supporting surface; a mounting seat at the top end of the connecting device; a spring disposed on the connecting device, the two ends of the spring are respectively slid against the top surface of the supporting seat and the bottom surface of the mounting seat, wherein the connecting device corresponds to the middle portion of the spring The part has a universal swing function, so that the mount can be selectively swinged relative to the support base; and a seat cushion mounted on the mount.

With this innovative and unique design, this creation is compared with the prior art, and the stress generated during operation is evenly distributed over the entire spring, in addition to extending the service life of the spring, and providing practical progress of the variable motion path. Sexuality and better industrial economy (utilization) benefits.

Please refer to Figures 1, 2 and 3 for a preferred embodiment of the present swing exercise machine, but such embodiments are for illustrative purposes only and are not limited by this structure in the patent application. The swinging exercise device includes a connecting device 10; a supporting base 20 mounted on the bottom end of the connecting device 10, the supporting base 20 is disposed on a supporting surface; and is mounted on the top end of the connecting device 10. The mounting seat 30; a spring 40 disposed on the connecting device 10, the two ends of the spring 40 are respectively abutted against the top surface of the supporting base 20 and the bottom surface of the mounting base 30, wherein the connecting device 10 corresponds to the spring The middle portion of the 40 has a universal swing function, so that the mount 30 can be selectively swinged relative to the support base 20; and a seat cushion 50 mounted on the mount 30.

The connecting device 10 includes a first pivot 11 mounted on the top surface of the support base 20, a connecting block 12 pivoted to the first pivot 11 and a second pivot pivotally connected to the connecting block 12. The ear 13 is fixed to the bottom surface of the mounting seat 30. In the preferred embodiment of the present invention, the first pivot 11 is rotatable relative to the support 20 by using at least one bearing 21 mounted in the support base 20. A first shaft hole 121 and a second shaft hole 122 are formed on the two ends of the connecting block 12, and the axes of the first shaft hole 121 and the second shaft hole 122 are perpendicular to each other, and the first shaft hole is perpendicular to each other. The second shaft hole 122 and the second shaft hole 122 are respectively disposed with a pivot 14 and the two ends of the connecting block 12 are pivotally connected to the first pivot 11 and the second pivot 13 respectively.

A first protrusion 22 is disposed on the top surface of the support base 20, and a second protrusion 31 is disposed on the bottom surface of the mounting base 30. The first protrusion 22 and the second protrusion 31 are coupled to the spring 40. The inner diameters are disposed and respectively inserted into the different ends of the spring 40, so that when the spring 40 is deformed, the end portion does not have a displacement phenomenon with respect to the support base 20 or the mounting seat 30, thereby improving the creation operation. The stability of the structure.

With the above-mentioned structural composition design, the following is the use of this creation: as shown in Figure 4-5, when you want to use this creation to slow down the discomfort caused by sitting in a bad sitting position, the user can ride The seat cushion 50 is straightened forward, and the hip muscle is directly used to cooperate with the waist force to operate the mount 30 to swing relative to the support base 20 to relieve the discomfort of back pain. The biggest difference between the present invention and the conventional hip fitness device is the connecting device 10. In the preferred embodiment of the present invention, the connecting device 10 includes a first pivot 11 , a connecting block 12 and a second pivot 13 . The three-section structure, and the portion that provides the universal rotation is located in the middle portion relative to the spring 40. Therefore, when the mounting seat 30 is swiveled relative to the support base 20, the load on the spring 40 is evenly dispersed. On the entire spring 40, stress concentration can be avoided and the service life of the spring 40 can be extended. Moreover, since the connecting device 10 of the present invention adopts a three-stage movable design, when the mounting seat 30 swings relative to the support base 20, the first pivoting ear 11, the connecting block 12 and the second pivoting ear 13 does not maintain a straight state, but is bent at any direction depending on the direction of the force applied, and the movement path of the mount 30 can be provided more varied.

Efficacy Description: The "swing fitness device" disclosed in this creation mainly uses the three-stage innovative unique structural pattern and technical features of the first pivot ear, the connecting block and the second pivot ear to make the present comparison [previous technique] In terms of the proposed structure, the stress generated during operation can be evenly distributed over the entire spring, in addition to extending the service life of the spring, and providing practical progress for the variable motion path.
