## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is based upon and claims priority under 35 U.S.C. 119 from Taiwan Patent Application No. 104217926 filed on Nov. 9, 2015, which is hereby specifically incorporated herein by this reference thereto.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a seated inversion table, especially to a seated inversion table that can prevent a user from over-inverting when using the seated inversion table.
2. Description of the Prior Arts
A seated inversion table is used for relieving discomfort caused by osteophytes, commonly referred to as bone spurs or parrot beak. In other words, the seated inversion table is rehabilitation equipment that allows a patient to appropriately exercise on it for stretching the abdominal muscles and back muscles.
According to Taiwan Patent No. M298454, the conventional seated inversion table is provided with a seat cushion assembly tiltably mounted between a front support component and a rear support component, a center of a first rod of the seat cushion assembly is mounted on an extendable rod, and two end portions of the first rod are tiltably mounted on two inner surfaces of two opposite ends of the rear support component which face to each other. The extendable rod is connected to a connecting tube through a second rod. The second rod is located under a sitting cushion of the seat cushion assembly. A center of the connecting tube is tiltably mounted on a connecting frame, and two opposite ends of the connecting tube are tiltably mounted on a hanging portion of the rear support component. The connecting frame is securely mounted on a rear surface of the back cushion.
When the patient performs inversion on the seated inversion table, the spaces between vertebras can be extended, aches caused by the osteophytes pressing on neurons are relieved, and abdominal muscles and back muscles stretch and get exercise at the same time. When the user sits on the seated inversion table and uses it, the back of the user lies against the seat back, the feet hook on the foot-clamping frame assembly, and the hands hold on and push the handle bars until the body tilts backward 180 degrees.
However, the conventional seated inversion table is not disposed with any protective structure for preventing the seated inversion table from over tilting. Thus, because the two end portions of the first rod are tiltably mounted on the two inner surfaces of two opposite ends of the rear support component which face to each other, when the user over tilts with the seat cushion assembly, the conventional seated inversion table cannot stop the inertia of inverting by the first rod abutting on the handle bars, which increases the possibility of injury to the user.
In addition, because a distance between two fixing rods of the foot-clamping frame assembly of the conventional seated inversion table is hard to adjust when the user sits on a sitting cushion of the seated inversion table, the user's foot cannot hook on the fixing rods firmly.
Besides, because the seated inversion table is designed for the particular purpose, the seated inversion table is not suitable for other purposes. When the seated inversion table is not in use, it is not easy to store the seated inversion table in the limited housing space of densely populated metropolitan area.
To overcome the shortcomings, the present invention provides a seated inversion table to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide a seated inversion table that can restrict and stop inertia during inversion to protect the user.
The seated inversion table has:

    
    
        a support frame assembly comprising:
        
            at least one rear support component,
            at least one front support component connected to the at least one rear support component, and
            a connecting tube, two opposite ends of the connecting tube securely mounted on the at least one front support component;

            a front swinging rod, two opposite ends of the front swinging rod tiltably mounted on the support frame assembly,
            a cushion bottom rod, one end of the cushion bottom rod securely mounted on the rear swinging rod of the seat back assembly, and another end of the cushion bottom rod securely mounted on the front swinging rod, and
            a sitting cushion movably mounted on the cushion bottom rod and the cushion bottom rod located on a bottom surface of the sitting cushion;
        
        
        a lower connecting tube assembly comprising:
        
            a lower connecting tube located on the bottom surface of the sitting cushion, one end of the lower connecting tube securely mounted at another end of the rear-rod-tilting frame of the seat back assembly,
            a guiding stand mounted on an outer surface of the lower connecting tube, and
            a band, one end of the band securely mounted on the connecting tube of the support frame assembly and detoured around the guiding stand;
        
        
        a rotating frame assembly comprising:
        
            a connecting frame tiltably mounted at a center of the front swinging rod of the seat cushion assembly, another end of the lower connecting tube securely mounted on the connecting frame, another end of the band mounted on the connecting frame, and
        
        
        a foot-clamping frame assembly securely mounted on the rotating frame assembly, and being adjustable in angle and distance relative to the rotating frame assembly.
    
    


One of the advantages of the present seated inversion table is that with the front swinging rod tiltably mounted on the support frame assembly, the front swinging rod will be located at an end of the stroke and abut on the upper bars when the user performs inversion on the seated inversion table. Thus, a range of an inversion angle is restricted and thereby the seated inversion table may not over tilt.

However, in another embodiment, the numbers of both the at least one rear support component 13 and the at least one front support component 14 are one. Each of the rear support component 13 and the front support component 14 is a U-shaped rod. The connecting tube 15 is connected between two arms of the U-shaped front support component 14. The curved tube 17 is connected between two arms of the U-shaped rear support component 13.
In accordance with FIG. 11, when a user performs inversion with the present seated inversion table, the user sits on the sitting cushion 33, the user's back lies against the back cushion 23, and the user's hands hold the upper bars 1231. Meanwhile, the user's hands push the upper bars 1231 and thereby the user's arms get exercise. Besides, when the user inclines backward with force and makes the user's back push the back cushion 23, the rear swinging rod 21 can be tilted forward, an angle between the sitting cushion 33 and the back cushion 23 is changed, and thereby the user's abdominal muscles stretch. In addition, the foot-clamping frame assembly 60 is moved away from the connecting tube 15 because the back cushion 23 pushes the lower connecting tube 41 and the connecting frame 51 through the rear-rod-tilting frame 22, the front swinging rod 31 is tilted upward with respect to the handle components 12 along with the connecting frame 51 moving forward, and the band 43 is stretched and deformed along with the connecting frame 51 moving forward, so that the user's leg muscles can be stretched. At this moment, the front swinging rod 31 is tilted toward the upper bars 1231.
With the user's hands keep pushing and shifting from the upper bars 1231 to the lower bars 1232, the rear swinging rod 21 will be tilted further and the angle between the sitting cushion 33 and the back cushion 23 is increased. At this time, the back cushion 23 pushes the lower connecting tube 41 and the connecting frame 51 through the rear-rod-tilting frame 22 so that the foot-clamping frame assembly 60 finally moves to a location above the back cushion 23, which achieves the purpose of inverting and exercising. Besides, the front swinging rod 31 abuts on the upper bars 1231 because of the driving of the connecting frame 51, and the band 43 is stretched completely because of being dragged by the connecting frame 51. Thus, the present seated inversion table may not be tilted toward the same direction further at this time.
Then refer to FIGS. 4 and 7 to 9. FIG. 4 illustrates storage process of the present seated inversion table after the exercise. First, the user can remove the handle bars 123, the connecting tube 15, the support covers 16, the back cushion 23, and the foot-clamping assembly 60. More precisely, after the second fixing elements 124 are removed, the handle bars 123 can be removed; after the third fixing elements 141 are removed, the connecting tube 15 can be removed. After the aforesaid components are removed, the seated inversion table is as shown in FIG. 7. Then after the first fixing elements 121 are removed, the two handle components 12 and the two rear support components 13 can be tilted.
After that, as shown in FIG. 8, the handle components 12 are tilted forward until the handle components 12 are parallel to the front support components 14. Then the rear swinging rod 21 and the front swinging rod 31 are tilted forward, making the sitting cushion 33 move forward and the front swinging rod 31 and the sitting cushion 33 parallel to the front support components 14. Then the upper end of the rear-rod-tilting frame 22 is tilted backward, making the connecting frame 51 tilt forward.
Finally, as shown in FIG. 9, the two rear support components 13 are tilted forward until the rear support components 13 are parallel to the front support components 14 to finish the storage process of the present seated inversion table. Then also refer to the FIG. 10, with the curved tube 17 bent backward, when the rear support components 13 are parallel to the front support components 14, the curved tube 17 can step away from the lower connecting tube 41 and make the lower connecting tube 41 accommodated in a curved space of the curved tube 17 to minimize a thickness of the folded seated inversion table.
Consequently, one of the advantages of the present seated inversion table is that with the front swinging rod 31 tiltably mounted on the support frame assembly 10, the front swinging rod 31 will be located at an end of the stroke and abut on the upper bars 1231 when the user performs inversion on the seated inversion table. Thus, a range of an inversion angle is restricted and thereby the seated inversion table may not over tilt. Another advantage of the present seated inversion table is that the connecting tube 15, the back cushion 23 and the foot-clamping assembly 60 are removable, and after the aforesaid components are removed, the present seated inversion table can be folded through tilting the handle components 12, the at least one rear support component 13, the front swinging rod 31, and the sitting cushion 33 to be parallel to the at least one front support component 14. After the removal and folding, the present seated inversion table is adapted to store and thereby decrease occupied space significantly and promote the efficiency of space utilization.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
