Exercising apparatus

## Abstract

An exercising apparatus has a front frame, a rear frame and a seat assembly. The rear frame is connected to the front frame and the seat assembly is mounted pivotally between the front frame and the rear frame. The seat assembly has a seat back, a seat, a leg holder, a front connecting rod and a lower connecting rod. When a user is in an inverted position, the user's body is stretched and pressure on the spine can be eliminated. With the relative movement between the seat back and the seat and the relative movement between the seat and the leg holder, the torso and femoral muscles of the user can be fully exercised.

## Background
BACKGROUND OF THE INVENTION
1. Field of Invention
The present invention relates to an exercising apparatus, and more particularly to an exercising apparatus that is provided for inverting a user and exercising the use's torso and femoral muscles.
2. Description of the Related Art
Discs of the spine separate vertebrae, allow vertebrae's movement and provide a shock absorbing effect. Nerves in the body leave the spine through the spaces between the vertebrae. Pressure of body weight on the discs and constant pounding from running can cause the discs to be compressed. The pressure on the nerves and discs may cause a frequent back pain and this is a big problem in daily life.
Inversion therapy involves hanging upside down to apply gentle traction to the spine. This increases the space between the vertebrae and reduces the pressure applied on the discs. Increasing the space between the vertebrae reduces the pressure on the nerves and discs, which means eliminating back pain. In addition, appropriate exercises of torso muscles can increase support to the spine and is also helpful to ease back pain.
A conventional inversion table comprises a frame and a table. The frame has two handgrips mounted on both side of the frame. The table is supported by the frame above the ground for pivotal movement about a horizontal axis and has an ankle clamp mounted on one end of the table. In use, a user lies on the table and fixes his ankle with the ankle clamp. Then the user pivots the table about the horizontal axis by griping the handgrips to an inverted position. However, the user's body is kept in a flat position and the torso muscles of the user are not used for inverting the user. Thus the conventional inversion table cannot provide any exercising effect to the user.
To overcome the shortcomings, the present invention provides an exercising apparatus to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an exercising apparatus such that a user can pivot from a sitting position to an inverted position and exercise the torso muscles of the user.
The exercising apparatus in accordance with the present invention comprises a front frame, a rear frame and a seat assembly.
The front frame has a damper mounted on the front frame.
The rear frame is connected to the front frame and has two hanging members and two handgrips. The hanging members and handgrips are mounted on the rear frame.
The seat assembly is mounted pivotally between the front frame and the rear frame and has a seat back, a seat, a leg holder, a front connecting rod and a lower connecting rod. The seat back is mounted pivotally between the hanging members and has a lower end. The seat is mounted pivotally on the lower end of the seat back and has a front end.
The leg holder is mounted pivotally on the front end of the seat, aligns with the damper and has a lower end and two holding bars. The holding bars are mounted on the lower end of the leg holder. The front connecting rod is mounted pivotally on the front end of the seat and has two ends. The ends are mounted on the rear frame. The lower connecting rod has a front end and a rear end. The front end is connected pivotally to the leg holder and the rear end is connected pivotally to the lower end of the seat back.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
With reference to FIGS. 1 and 2, an exercising apparatus in accordance with the present invention comprises a front frame (10), a rear frame (20) and a seat assembly (30).
The front frame (10) has a bottom rod, two supporting rods (11), a connecting rod (12) and a damper (13). The bottom rod has two ends and the supporting rods (11) are mounted respectively on the ends of the bottom rod. The connecting rod (12) is mounted between the supporting rods (11). The damper (13) is mounted on the connecting rod (12).
The rear frame (20) is connected to the front frame (10) and has a bottom rod, two supporting rods (21), two handles (22), two hanging members (23) and two handgrips (24). The bottom rod has two ends and the supporting rods (21) are mounted respectively on the ends of the bottom rod. The supporting rods (21) each have an upper end, and the handles (22) are mounted respectively on the upper ends of the supporting rods (21). The hanging members (23) are mounted respectively on the supporting rods (21) and each have an open slot. The handgrips (24) are mounted respectively on the supporting rods (21).
With further reference to FIG. 3, the seat assembly (30) is mounted pivotally between the front frame (10) and the rear frame (20) and has a seat back (31), a seat (32), a leg holder (33), a front connecting rod (34) and a lower connecting rod (35). The seat back (31) is mounted pivotally between the hanging members (23) and has a rear side, a connecting post (312), and a U-shaped connector (311). The connecting post (312) is mounted on and protruded downward from the rear side of the seat back (31) and has a lower end. The U-shaped connector (311) is mounted on the lower end of the connecting post (312) and has two ends. The ends of the U-shaped connector (311) are mounted pivotally and respectively in the open slots of the hanging members (23).
The seat (32) is connected pivotally to the lower end of the connecting post (312) of the seat back (31) and has a front end. The leg holder (33) is connected pivotally to the front end of the seat (32), aligns with the damper (13) and has a lower end and two holding bars (331). When the leg holder (33) pivots rearward and abuts the damper (13), the impulse of the leg holder (33) can be effectively absorbed by the damper (13). The holding bars (331) are mounted on the lower end of the leg holder (33) for holding the user's ankles. The holding bars (331) each have an optional sponge sleeve mounted around the holding bar (331).
The front connecting rod (34) is U-shaped and has a bottom rod and two side rods. The bottom rod is mounted pivotally on the front end of the seat (32) and has two ends. The side rods each have a proximal end and a distal end. The proximal end is connected to one end of the bottom rod and the distal end is mounted pivotally on the supporting rod (21) of the rear frame (20).
The lower connecting rod (35) has a front end and a rear end. The front end is connected pivotally to the leg holder (33) and the rear end is connected pivotally to the lower end of the connecting post (312).
In use, the user sits on the seat assembly (30) and holds the handles (22) of the rear frame (20) with hands and the holding bars (331) with legs. With further reference to FIGS. 4 and 5, when the user is inverting, the seat back (31) and the seat (32) are pivoted relative to the rear frame (20) and the hanging members (23). Hands of the user hold the handles (22) and gradually move to the handgrips (24) for keeping balance. The angle between the seat back (31) and the seat (32) is increasing during the pivotal rotation of the seat assembly (30). At this time, the user's abdominal muscles are extended and dorsal muscles are contracted so an exercising effect to the torso muscles is achieved. In addition, the angle change between the seat (32) and the leg holder (33) also provides an exercising effect to the user's femoral muscle.
With further reference to FIGS. 5 and 6, when the user is in an inverted position, the seat back (31), seat (32) and leg holder (33) are in alignment with each other. The user's body is inverted and stretched so pressure of body weight on the spine can be eliminated. The back pain caused by the pressure can be eased by the inversion condition.
Furthermore, with the relative movement between the seat back (31) and the seat (32) and the relative movement between the seat (32) and the leg holder (33), the torso and femoral muscles of the user can be fully exercised. Therefore, the exercising apparatus in accordance with the present invention has multiple functions of inverting the user to release the pressure on the spine and exercising the torso and femoral muscles of the user.
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 function of the invention, the disclosure is illustrative only. Changes may be made in detail, 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.
