Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a push-up exerciser, especially to a push-up exerciser that helps a user to perform push-ups and to train himself.

2. Description of the Prior Art(s)

A push-up is a common exercise that trains pectoral muscles, rectus abdominus, transverse abdominus, etc of a user. Although doing the push-ups improves the user's fitness, the user's body also bears loads when doing the push-ups. Especially, beginners often overestimate their capacity and perform too many push-ups, which may damage their muscles. Thus, some conventional push-up exercisers are designed to help the users to perform the push-ups. However, the conventional push-up exercisers have complicated structures and therefore are expensive.

To overcome the shortcomings, the present invention provides a push-up exerciser to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a push-up exerciser. The push-up exerciser has a base, two handgrips, a connecting rod having two ends respectively connected pivotally to the base and a supporter, at least one resilient element connected to the connecting rod and the supporter, a roller pivotally mounted on a lower end of the supporter, and a pad pivotally mounted on an upper end of the supporter.

A user places his/her abdomen on the pad, grasps the handgrips and then bends or straightens his/her arms to perform push-ups. Since the at least one resilient element tends to pull the supporter and the connecting rod so the pad tends to support the abdomen of the user, load applied to the arms of the user is reduced and is less than weight of the user. The push-up exerciser has simplified structure, low manufacturing cost and helps the user to safely perform push-ups.

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.

With further reference to FIG. 3, the base 10 is T-shaped and has a longitudinal rod 13, a transverse rod 14 and two mounting ends 11. The longitudinal rod 13 has a front end and a rear end. The transverse rod 14 is transversely attached to the front end of the longitudinal rod 13. The mounting ends 11 of the base 10 are respectively defined as two opposite ends of the transverse rod 14. Each mounting end 11 of the base 10 is hollow and cylindrical and has multiple positioning holes 12 formed through the mounting end 11 of the base 10.

The handgrips 20 are respectively mounted beside two opposite sides of the base 10. Each handgrip 20 has a mounting end 21, a standing end and a holding portion 22. The mounting end 21 of the handgrip 20 is transversely curved, is hollow and cylindrical, is axially mounted through a corresponding mounting end 11 of the base 10 and has multiple positioning holes 23. The positioning holes 23 of the handgrip 20 are formed through the mounting end 21 of the handgrip 20 and selectively align with the positioning holes 12 of the corresponding mounting end 11 of the base 10. The standing end of the handgrip 20 protrudes vertically and is placed on a plane. The holding portion 22 is defined between the standing end and the mounting end 21 of the handgrip 20 and is upwardly curved.

The positioning plates 91 are resilient and are respectively mounted in the mounting ends 21 of the handgrips 20. Each positioning plate 91 has a positioning protrusion 911. The positioning protrusion 911 is mounted through a pair of positioning holes 12, 23 of the base 10 and the handgrip 20. Thus, the handgrips 20 are held in specific positions relative to the base 10. The cushion rings 92 are respectively mounted around the mounting ends 21 of the handgrip 20.

The connecting rod 30 has an upper end, a lower end and a middle. The lower end of the connecting rod 30 is pivotally connected to a rear of the base 10 and is pivotally connected to the rear end of the longitudinal rod 13 of the base 10.

The supporter 40 is curved, is pivotally connected to the upper end of the connecting rod 30 and has an upper end, a lower end and a middle. The middle of the supporter 40 is pivotally connected to the upper end of the connecting rod 30.

The at least one resilient element 50 is connected to the connecting rod 30 and the supporter 40 and is disposed below the upper end of the connecting rod 30 and the middle of the supporter 40. Each of the at least one resilient element 50 may be a tension spring.

The stopper 60 may be a wheel, may be rubber, is pivotally mounted on the supporter 40 and is disposed above the upper end of the connecting rod 30.

The roller 70 is pivotally mounted on the lower end of the supporter 40, is disposed in front of the base 10 and is disposed in front of the transverse rod 14 of the base 10.

The pad 80 is pivotally mounted on the upper end of the supporter 40.

Preferably, the push-up exerciser further comprises a rear shaft 31, two rear sleeves 32, two rear knobs 33, a front shaft 41, two front sleeves 42 and two front knobs 43, and the push-up exerciser comprises two resilient elements 50. The rear shaft 31 is transversely mounted through the connecting rod 30, is disposed adjacent to the middle of the connecting rod 30 and has two opposite ends. The rear sleeves 32 are rotatably mounted around the rear shaft 31 and are respectively disposed adjacent to the ends of the rear shaft 31. The rear knobs 33 are securely mounted on the ends of the rear shaft 31. The front shaft 41 is transversely mounted through the supporter 40, is disposed adjacent to the lower end of the supporter 40 and has two opposite ends. The front sleeves 42 are rotatably mounted around the front shaft 41 and are respectively disposed adjacent to the ends of the front shaft 41. The front knobs 43 are securely mounted on the ends of the front shaft 41. The two resilient elements 50 are respectively disposed beside the connecting rod 30 and the supporter 40. Each resilient element 50 extends from a front to the rear of the base 10 and has two mounting ends 51. The mounting ends 51 of the resilient element 50 are respectively connected to a corresponding end of the rear shaft 31 and a corresponding end of the front shaft 41, and to a corresponding rear sleeve 32 and a corresponding front sleeve 42.

With further reference to FIG. 4, when using the push-up exerciser, a user places his/her abdomen on the pad 80 and grasps the handgrips 20. With further reference to FIG. 5, then the user bends his/her arms and his/her body moves downwardly. Thus, the abdomen of the user pushes the pad 80 downwardly, the supporter 40 pivots relative to the connecting rod 30 and the roller 70 on the lower end of the supporter 40 rolls forward. Consequently, the connecting rod 30 pivots forwardly and downwardly toward the base 10. When the supporter 40 and the connecting rod 30 pivot, the at least one resilient element 50 stretches. The supporter 40 and the connecting rod 30 stop pivoting when the connecting rod 30 abuts the stopper 60. Meanwhile, the user's arms are bent at comfortable angles. Moreover, since the at least one resilient element 50 tends to pull the supporter 40 and the connecting rod 30 so the pad 80 tends to support the abdomen of the user, load applied to the arms of the user is reduced and is less than weight of the user.

When the user gradually straightens his/her arms, the user's body moves upwardly, and the at least one resilient element 50 pulls the supporter 40 and the connecting rod 30 so the pad 80 also moves upwardly to support the user.

The push-up exerciser as described has simplified structure and low manufacturing cost. Moreover, the push-up exerciser helps the user to safely perform push-ups, no excessive load is applied to the user's muscles and the user's muscles are not injured
