Abstract

A sit-up exerciser has a body and a back bracket. The back bracket is mounted on and pivotally connects to the body. Multiple elastic elements transversely connect to the lower end of the back bracket and the body. When a user's back presses against the back bracket, the back bracket can be pivoted relative to the body. Meanwhile, the user should resist the resilient force of the elastic elements to keep exercising. Furthermore, the exerciser has a small volume for convenient storage.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a sit-up exerciser, and more particularly to a sit-up exerciser with a small volume and easy to be moved.
  • 2. Description of the Related Art
  • At present, all kinds of exercisers are introduced into the market for people to exercise indoor such as walk exercisers, weight lifters, etc. However, a conventional sit-up exerciser is rare in the market and is usually set up in the gym. Furthermore, the conventional sit-up exerciser has a large volume and a heavy weight with inconvenient moving.
  • Therefore, the invention provides a sit-up exerciser to mitigate or obviate the aforementioned problems.
  • SUMMARY OF THE INVENTION
  • The main objective of the present invention is to provide a sit-up exerciser with a small volume and easy to be moved.
  • 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.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a sit-up exerciser in accordance with the present invention;
  • FIG. 2 is an exploded perspective view of the sit-up exerciser in FIG. 1;
  • FIG. 3 is another perspective view of the sit-up exerciser in FIG. 1;
  • FIG. 4 is an operational side view of the sit-up exerciser in FIG. 1;
  • FIG. 5 is another operational side view of the sit-up exerciser in FIG. 1; and
  • FIG. 6 is an operational perspective view the sit-up exerciser in FIG. 1.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to FIGS. 1-3, a sit-up exerciser in accordance with the present invention has a body (10), a back bracket (20) and two armrest assemblies (30).
  • The body (10) has two parallel and curved side stretchers (11), a back stretcher (12), a seat (15) and a front stretcher (14). Each side stretcher (11) has a foot integrally formed in an end of the side stretcher (11) so that the foot can stand on the ground to support the body (10). The back stretcher (12) is provided transversely between the side stretchers (11) and has multiple evenly-spaced hooks (120) respectively defined in the back stretcher (12) and two fasteners (13) mounted on a middle of the back stretcher (12). The seat (15) is mounted transversely between front parts of the side stretchers (11). The front stretcher (14) is mounted transversely in a low front end of the seat (15).
  • The back bracket (20) is mounted between and extends upward from the side stretchers (11) and has two rods (21), multiple evenly-spaced cylinders (22), a post (23) and multiple elastic elements (24). The rods (21) are respectively mounted pivotally on the fasteners (13) of the body (10) and respectively have an lower end. The cylinders (22) are mounted transversely between the rods (21). The post (23) is mounted between the lower ends of the rods (21), aligns with the back stretcher (12) and has multiple hooks (230) corresponding to the hooks (120) on the back stretcher (12). The elastic elements (24) are mounted between the back stretcher (12) and the post (23) and each elastic element (24) connects to the corresponding hooks (120) on the back stretcher (12) and the post (23). In this preferred embodiment of the present invention, the elastic elements (24) are springs.
  • The armrest assemblies (30) are mounted respectively on two sides of the body (10). Each armrest assembly (30) has a mounting bar (31) and an armrest (32). The mounting bar (31) engages with the front stretcher (14). The armrest (32) is arcuate and connects to the mounting bar (31).
  • With further reference to FIG. 4, a user sits in the seat (15) and leans against the cylinders (22). Arms of the user can rest on the armrests (32). When the user's back presses against the back bracket (15), the back bracket (20) can be pivoted relative to the body (10). Meanwhile, the user should resist the resilient force of the elastic elements (24) to keep exercising.
  • With further reference to FIGS. 5 and 6, the user's back stops pressing against the back bracket (15), the resilient force of the elastic elements (24) pushes the back bracket (20) to resume to an original status. Because the structure of the present invention is simple, the present invention occupies a small volume and is easy to be moved.
  • It is to be understood, however, that 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 details, 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.
