## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an exercise machine, especially to an exercise machine that helps a person to safely perform an exercise similar to a push-up.
2. Description of the Prior Art
Push-ups are a common calisthenic exercise. Push-up focuses most of the body weight of an exerciser on his or her triceps muscles. The exerciser's body weight is applied to the triceps muscles during downward and upward movement. A beginning exerciser tends to overestimate his or her capacity and performs too many push-ups, which may damage the triceps muscles.
To overcome the shortcomings, the present invention provides an exercise machine to mitigate or obviate the aforementioned problem.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide an exercise machine that allows an exercise similar to a push-up to be performed safely.
The exercise machine in accordance with the present invention has a base, a lever, a pad, a leveling rod and a resilient element and may have at least one vibrator.
The base has at least one bracket.
The lever is attached pivotally to the bracket and has a front end, a rear end and a handlebar attached to the front end.
The pad is attached to the rear end of the lever.

The bracket (13) is attached to and protrudes up from the base bar (11) between the front end and the rear end of the base bar (11), has two sides, a lever pivot hole (132) and a leveling pivot hole (133) and may have two side covers (131), a bumper seat (134) and a secondary bumper (135). The two side covers (131) are mounted respectively on the sides of the bracket (13). The bumper seat (134) is attached to the bracket (13) and has a top. The secondary bumper (135) is attached to and protrudes up from the top of the bumper seat (134).
The connector (14) is attached to and protrudes up from the base bar (11) near the rear end and may be a hook.
The bumper (15) is attached to and protrudes up from the top of the base bar (11) near the front end.
The lever (20) is attached pivotally to the lever pivot hole (132) in the bracket (13), has a front end, a rear end and a handlebar (211) and may have a front segment (21) and a rear segment (22). The handlebar (211) is attached to the front end of the lever (20) and may have a box (212). The box (212) may have a counter (213).
With further reference to FIGS. 4 and 5, the pad (40) is attached to the rear end of the lever (20) and has a pad body (41) and a mounting bracket (42). The pad body (41) has a bottom surface. The mounting bracket (42) is attached to the bottom surface of the pad body (41), connects the pad body (41) to the lever (20) and has two wings (421) and a pin (425). The wings (421) protrude down and are connected pivotally to the rear end of the lever (20), and each wing (421) has a lever pivot hole (422), a leveling pivot hole (423) and a through hole (424). The lever pivot holes (422) are aligned with each other and are connected pivotally to the rear end of the lever (20). The leveling pivot holes (423) are aligned with each other. The through holes (424) are aligned with each other. The pin (425) is mounted in the two through holes (424).
The leveling rod (30) is connected parallel to the lever (20) and pivotally to the leveling rod pivot holes (133) in the bracket (13) and the leveling pivot holes (423) in the wings (421) on the mounting bracket (42).
The resilient element (50) is mounted between the pad (40) and the base (10), may be a spring and has an upper end and a lower end. The upper end of the resilient element (50) is attached to the pin (425). The lower end is attached to the connector (14) on the base (10).
With further reference to FIGS. 6 and 7, the vibrator (65) is attached to the bottom surface of the pad body (41) and has a controlling system (60). The controlling system (60) controls the operation of the at least one vibrator (65) and comprises a power regulator (64), an electrical cable (61), an optional switch (62) and an optional rheostat (63). The power regulator (64) connects selectively to an external power supply, transforms and converts external power and supplies electrical power to the at least one vibrator (65). The electrical cable (61) connects the power regulator (64) to the at least one vibrator (65) and may extend through the box (212) and be mounted in the lever (20) or may be connected directly from the power regulator (64) to the at least one vibrator (65). The switch (62) is mounted in the electrical cable (61), turns the at least one vibrator (65) on or off and may be mounted in the box (212). The rheostat (63) is mounted in the electrical cable (61), controls how much power is sent to the at least one vibrator (65) and how much the at least one vibrator (65) vibrates and may be mounted in the box (212).
With reference to FIG. 8, the controlling system (60) may be connected to the at least one vibrator (65) externally with the switch (62) and the rheostat (63) set in a control housing (66). The control housing (66) is mounted in line with the electrical cable (61) between the power regulator (64) and the at least one vibrator (65) and houses the switch (62) and the rheostat (63).
To use the exercise machine, a person places his or her abdomen on the pad body (41) and grasps the handlebar (211). When the person leans his or her body weight forward, the front end of the lever (20) lowers and applies a significant percentage of the body weight to the user's triceps muscles. When the person lean his or her body weight backward, the front end of the lever (20) rises, and weight is released from the triceps muscles. When the triceps muscles become sore or experience pain, the can easily release weight from the triceps muscles without injuring the muscles.
The exercise machine in accordance with the present invention helps an exerciser to safely perform an exercise similar to push-ups.
