Benefits of technology

[0006] The present invention is to mitigate and / or obviate the disadvantage of the conventional exercising device.
[0007] The primary objective of the present invention is to provide an exercising device, wherein the user can operate the exercising device to achieve the purpose of exercising the user's waist.
[0008] Another objective of the present invention is to provide an exercising device, wherein the longitudinal bar of the main frame is rested on the stop block, thereby preventing the main frame from being entirely rested on the ground due to an excessive rotation, and preventing the user's back from being injured due to excessive bending so as to protect the user's safety.
[0009] A further objective of the present invention is to provide an exercising device, wherein each of the rocking bars is arc-shaped to satisfy the ergonomic design, so that the user can operate the exercising device in a comfortable and safe manner.
[0010] A further objective of the present invention is to provide an exercising device, wherein the user can operate the exercising device easily and conveniently by the restoring force of each of the two elastic members, thereby facilitating the user operating the exercising device.

Problems solved by technology

However, the user's back is not easily rested on the main frame 10, thereby causing an uncomfortable sensation to the user.
In addition, the main frame 10 is easily rested on the ground entirely due to an excessive rotation, so that the user's back is easily injured due to excessive bending, thereby causing danger to the user.
Further, the user has to exert a larger force to operate the conventional exercising device, so that the user consumes much energy and cannot achieve the exercising effect.

Embodiment Construction

[0026] Referring to the drawings and initially to FIGS. 2 and 3, an exercising device in accordance with the preferred embodiment of the present invention comprises a main frame 20, a retractable bar 30, a pivot bar 40, a stop block 50, two rocking bars 60, and two elastic members 70.

[0027] The main frame 20 is substantially I-shaped, and includes a longitudinal bar 21, a first transverse bar 27 mounted on a first end of the longitudinal bar 21, and a second transverse bar 23 mounted on a second end of the longitudinal bar 21. The first end of the longitudinal bar 21 of the main frame 20 is formed with a plurality of adjusting holes 26. The second end of the longitudinal bar 21 of the main frame 20 is provided with two connecting rods 22 located adjacent to the second transverse bar 23. The longitudinal bar 21 of the main frame 20 has a mediate portion provided with a substantially U-shaped pivot base 28.

[0028] The exercising device further comprises a backrest 25 mounted on the f...

Abstract

An exercising device includes a main frame, a pivot bar pivotally mounted on the main frame, a stop block mounted on the pivot bar and rested on the main frame when the main frame approaches the pivot bar, two rocking bars mounted on the main frame, and two elastic members each biased between the main frame and the pivot bar. Thus, the longitudinal bar of the main frame is rested on the stop block, thereby preventing the main frame from being entirely rested on the ground due to an excessive rotation, and preventing the user's back from being injured due to excessive bending so as to protect the user's safety.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an exercising device, and more particularly to an exercising device for exercising a user's waist. [0003] 2. Description of the Related Art [0004] A conventional exercising device in accordance with the prior art shown in FIG. 1 is used to exercise the user's waist and comprises a bent main frame 10, a seat 12, and two handles 14. In operation, the user is seated on the seat 12, with his / her two hands holding the operation handle 14, and with his / her back being rested on the main frame 10. Then, when the user is moved backward, the main frame 10 is rotated, so that the user's upper body is moved with the main frame 10 so as to exercise the user's waist [0005] However, the user's back is not easily rested on the main frame 10, thereby causing an uncomfortable sensation to the user. In addition, the main frame 10 is easily rested on the ground entirely due to an excessive rotation, so ...
