Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an exercising apparatus and more particularly, to a push-and-pull type waist training exerciser.

2. Description of the Related Art

Various multipurpose exercising machines have been disclosed for exercising different parts of the body, and have appeared on the market. These exercising machines are commonly heavy, bulky, and complicated, not suitable for home use. Therefore, people may use small exercising apparatus, such as spring grips, chest developers, and etc. to exercise the body at home. However, these small exercising apparatus have monotonous and provide usually only one simple operation mode for training a specific part of the body. People may have to prepare several small exercising apparatus in order to train different parts of the body.

Therefore, it is desirable to provide a simple structure of exerciser, which is practical for training different parts of the body.

SUMMARY OF THE INVENTION

It is a primary objective of the present invention to provide a push-and-pull type waist training exerciser, which provides various operation modes to train the muscles of different parts of the body.

It is another objective of the present invention to provide a push-and-pull type waist training exerciser, which has a simple structure.

To achieve these objectives of the present invention, the push-and-pull type waist training exerciser comprises a base, a shaft, an operating member, a retaining member, and a plurality of spring members. The base has an axial through hole and a plurality of retaining portions. The shaft is axially moveably inserted through the axial through hole of the base. The operating member is fixedly fastened to a first end of the shaft for holding by user's hands. The retaining member is fixedly fastened to a second end of the shaft. The retaining member has a plurality of retaining portions corresponding to the retaining portions of the base. The spring members each have a first end coupled to one of the retaining portions of the base and a second end coupled to one of the retaining portions of the retaining member for imparting a resistance to the user when the shaft is moved relative to the base by the user.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 and 2, a push-and-pull type waist training exerciser 10 provided by a preferred embodiment of the present invention is shown comprising a base 11, a shaft 21, an operating member 31, a retaining member 41, a plurality of spring members 51, and two support members 61.

The base 11 is shaped like a rectangular block comprising an axial through hole 12 extended through the top and bottom sides thereof, two receiving chambers 14 symmetrically disposed at two opposite sides, a plurality of retaining portions 16, which are recessed holes in this embodiment and symmetrically disposed above the receiving chambers 14, a plurality of notches 18 symmetrically disposed below the receiving chambers 14 corresponding to the retaining portions 16, and a transverse tube 19 fixedly provided at the top side.

The shaft 21 is a rod member inserted through the axial through hole 12 of the base 11 and axially movable in the axial through hole 12.

The operating member 31 is fastened to one end of the shaft 21, comprising two first grips 32 forwardly extended from the front side thereof and two second grips 34 symmetrically disposed at two opposite lateral sides.

The retaining member 41 is fastened to the other end of the shaft 21, comprising a plurality of retaining portions 42, which are recessed holes in this embodiment and symmetrically disposed at two sides corresponding to the retaining portions 16 of the base 11.

The spring members 52 are narrow elongated elastic rubber members respectively inserted through the notches 18 and set in the receiving chambers 14. Each of the rubber members has a first head portion 52, which is provided at the first end of the spring member and coupled to one retaining portion 16 of the base 11, a second head portion 54, which is provided at the second end of the spring member and coupled to one retaining portion 42 of the retaining member 41, and a body portion, which is connected between the first and second head portions 52, 54 and has a diameter smaller than that of the first and second head portions 52, 54.

The two support members 61 are respectively fastened to the two distal ends of the transverse tube 19 of the base 11 for supporting on a part of the user's body or for pulling by the user during exercise.

FIGS. 3 and 4 show one application example of the push-and-pull type waist training exerciser. As illustrated, the user is in a sitting posture having the two support members 61 rested on the knees (or thighs) and the two second grips 34 set in the user's armpits. At this time, the user holds the two first grips 32 with the hands, and then moves the first grips 32 vertically up and down while alternatively bending and lifting the upper body. When bending the upper body as shown in FIG. 4, the operating member 31 is forced to move the shaft 21 axially downwards relative to the base 11, thereby causing the retaining member 41 to stretch the spring members 51, which impart a resistance to the user. Therefore, the muscles of the user's waist and abdomen are trained.

FIGS. 5 and 6 show another application example of the push-and-pull type waist training exerciser. As illustrated, the user is in a sitting posture having the feet pressed on the operating member 31 against the floor and the hands holding the two support members 61 to move the support members 61 vertically up and down while alternatively bending and lifting the upper body. When bending the upper body as shown in FIG. 6, the base 11 is forced downwards along the shaft 21 to stretch the spring members 51, thereby causing the spring members 51 to give a resistance to the user. Therefore, the muscles of the user's waist and abdomen are trained.

FIGS. 7 and 8 show still another application example of the push-and-pull type waist training exerciser. As illustrated, the operating member 31 is stopped at the user's abdomen, and the user is holding the support members 61 with the hands and then alternatively pulling and releasing the support members 61. When pulling the support members 61 upward toward the abdomen, as shown in FIG. 8, the base 11 is moved upwards along the shaft 21 to stretch the spring members 51, thereby causing the spring members 51 to give a resistance to the user. Therefore, the muscles of the user's hands are trained.

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.
