Powered body inversion exerciser
A powered body inversion exerciser includes a body having a base and an inversion table pivoted to the base, a power controller, which has a power-generating circuit, a spare power circuit, a power drive circuit for driving the inversion table to rotate relative to the base, and a safety control circuit all electrically connected together, and a hand control display electrically connected to the power controller. The spare power circuit provides electricity to the safety control circuit for returning the inversion table from an inversion position to an upright position when the supply of electricity of the power-generating circuit is abnormal. The hand control display is operated by a user to send a control signal to the power controller for controlling operation of the power controller.
1. Field of the Invention
The present invention relates generally to an electrically powered inversion exercise apparatus for inversing human body and more particularly, to a safety powered body inversion exerciser that automatically returns the inversion table to the upright position when the power supply is abnormal.
2. Description of the Related Art
A conventional body inversion exerciser essentially comprises a base, and a table pivotally mounted on the base and turnable relative to the base between an upright position and an inversion position. When in use, the user has the back supported on the table, and then shifts the center of gravity of the body to bias the table relative to the base from the upright position to the inversion position. When a user uses an inversion exerciser at the first time, the user may be not familiar with the biasing action of the table. At this time, the user may push the body against the table heavily or in a rush, causing the body inversion exerciser to fall to the floor. An accident or injury may occur in this case.
Because it is difficult to control the biasing speed and positioning of the table of a conventional inversion exerciser, many people are afraid of using a conversion exerciser. In order to eliminate this problem, electrically powered inversion exercisers are developed. These powered inversion exercisers commonly use a power drive unit to control biasing of the table between the upright position and the inversion position. However, this humanized design is still not satisfactory in function. Because the power drive unit is electrically operated, the user cannot move away from the table of the powered inversion exerciser in time or return the table of the powered inversion exerciser to the upright position during exercise when the power supply is abnormal.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is the primary objective of the present invention to provide a powered body inversion exerciser, which automatically returns the inversion table to the upright position when the power supply is abnormal.
To achieve this objective of the present invention, the powered body inversion exerciser comprises a body having a base and an inversion table pivotally mounted on the base and turnable relative to the base between an upright position and an inversion position, a power controller having a power-generating circuit, a spare power circuit, a power drive circuit and a safety control circuit all electrically connected together, and a hand control display. The power-generating circuit provides electricity to the spare power circuit, the power drive circuit and the safety control circuit, and the spare power circuit stores electricity from the power-generating circuit during normal functioning of the power-generating circuit. The power drive circuit actuates the inversion table to rotate relative to the base. The safety control circuit is capable of stopping the inversion table from rotation relative to the base and actuating the power drive circuit to return the inversion table to the upright position. The spare power circuit provides electricity to the safety control circuit for returning the inversion table to the upright position when the supply of electricity of the power-generating circuit is abnormal. The hand control display is electrically connected to the power controller for sending a control signal to the power controller for controlling operation of the power controller.
Preferably, the hand control display comprises a key entry circuit, a system processing circuit and a signal output circuit. The key entry circuit is operated by a user to output a first signal to the system processing circuit, and then the system processing circuit outputs a second signal to the signal output circuit after the first signal is processed, and then the signal output circuit outputs the control signal to the power controller for controlling operation of the power controller.
Preferably, the power controller further comprises a position detection circuit for detecting the position of the inversion table relative to the base, and the hand control display further comprises a detection display circuit for indicating detection result of the position detection circuit.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The body 10 comprises a base 12, and an inversion table 14 pivotally mounted on the base 12 and turnable between an upright position and an inversion position (not shown).
The power controller 20 is installed in the body 10, comprising a power-generating circuit 22, a spare power circuit 24, a power drive circuit 26, a safety control circuit 28, and a position detection circuit 30 all electrically connected together (see
The hand control display 40 is installed in the body 10 and electrically connected to the power controller 20. The hand control display 40 comprises a key entry circuit 42, a system processing circuit 44, a signal output circuit 46, and a detection display circuit 48 (see
During normal electricity supply status of the power-generating circuit 22, the user can use the key entry circuit 42 of the hand control display 40 to control the power drive circuit 26 of the power controller 20, causing it to turn the inversion table 14 relative to the base 12 from the upright position to the inversion position. At this time, the position detection circuit 30 of the power controller 20 detects the position of the inversion table 14 relative to the base 12, and the detection result is indicated through the detection display circuit 48 of the hand control display 40. Therefore, the user knows the position status of the inversion table 14 relative to the base 12 during exercise. Further, when the user feels uncomfortable during exercise, the user can control the safety control circuit 28 to stop the inversion table 14 from biasing relative to the base 12. If the supply of electricity of the power-generating circuit 22 is abnormal, the spare power circuit 24 will immediately provide electricity to the safety control circuit 28, causing it to stop the inversion table 14 from biasing relative to the base 12 and to return the inversion table 14 to the upright position.
As indicated above, the power controller 20 of the powered body inversion exerciser 1 comprises a spare power circuit 24 and a safety control circuit 28 to give an added protection to the user. Further, the design of the position detection circuit 30 enables the user to know the position status of the inversion table 14 relative to the base 12. Therefore, the user can use the powered body inversion exerciser 1 safely.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
