Description

BACKGROUND OF THE INVENTION

The present invention is related to an exerciser which can exercise a user's arms, waist and legs. Moreover, the exerciser can provide massaging effect for a user's waist.

An exerciser is used for exercising a user's body. For example, a swinging ring is used to exercise a user's waist. However, the swinging ring cannot provide exercising effect for the muscle of other parts of the user's body.

There is another type of exerciser for exercising a user's waist. Such exerciser has two handles and a rocking bar. A spherical body is disposed at lower end of the rocking bar. The user can lean the exerciser against his/her waist and hold the handles with two hands to rock the rocking bar for achieving an exercising effect.

However, such exerciser has some shortcomings as follows:

• 1. The exerciser can simply exercise the user's waist, while failing to provide exercising effect for the muscle of any other part of the user's body.
• 2. The exerciser cannot provide massaging effect for the user's waist.

SUMMARY OF THE INVENTION

It is therefore a primary object of the present invention to provide an exerciser which has simple structure and can exercise a user's arms, waist and legs. In addition, the exerciser can provide massaging effect for a user's waist.

According to the above object, the exerciser can be tied on a user's waist by means of a waist belt. The exerciser includes a substantially -shaped metal frame body composed of a central shaft, two handle shafts and two oblique shafts. Two foam-made handles are respectively fixedly mounted on the handle shafts for a user's hands to hold. An inner tube is rotatably mounted on each oblique shaft. A foam material is fixedly disposed around the inner tube for leaning against two sides of a user's waist to provide massaging effect for the waist. Two bearings are fitted around the central shaft and a fitting tube is rotatably fitted on the bearings. A swinging plate is perpendicularly disposed at front end of the fitting tube. A weight block is disposed on the swinging plate. In use, a user can use his/her body to revolve the swinging plate, weight block and the fitting tube about the central shaft to exercise his/her arms, waist and legs.

The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIGS. 1 to 3. The exerciser of the present invention includes a substantially -shaped metal frame body 10 having a central shaft 11, two handle shafts 12 obliquely connected with the central shaft 11 and two oblique shafts 13 obliquely connected with the central shaft 11.

Two foam-made handles 14 are respectively fixedly mounted on the handle shafts 12 for a user's hands to hold.

Referring to FIGS. 1 and 4, a plastic-made inner tube 15 is rotatably mounted on each oblique shaft 13. The inner tube 15 has a diameter slightly larger than the diameter of the oblique shaft 13. A foam material 16 having arched face is fixedly disposed around the inner tube 15 for leaning against two sides of a user's waist to provide massaging effect for the waist. A plug 17 is disposed at outer ends of the inner tube 15 and the foam material 16. The plug 17 has a ring member 18. As shown in FIG. 5, a waist belt 19 is connected between two opposite ring members 18. The waist belt 19 can be tied on a user's waist.

Two bearings 20 are fitted around the central shaft 11 at an interval. A hollow fitting tube 21 is fitted on the bearings 20. The fitting tube 21 has a rear circular tubular section and a front square tubular section. The central shaft 11 is fitted in the fitting tube 21. An upper side of the front end of the fitting tube 21 is formed with a recess 22. A bottom of the fitting tube 21 is formed with a thread hole 23.

The exerciser of the present invention further includes an L-shaped swinging plate 24 having a pivot section 25 on one side. A pin 26 is fitted through the fitting tube 21 and the pivot section 25 which is positioned in the recess 22. Accordingly, the swinging plate 24 can be pivoted relative to the fitting tube 21.

A lower section of the swinging plate 24 is formed with a hole 27. A bolt 28 is passed through the hole 27 and screwed in the thread hole 23 to lock the swinging plate 24 on the fitting tube 21.

The exerciser of the present invention further includes a weight block 30 having a certain weight (about within 1-5 kilograms). The swinging plate 24 is formed with a slot 241 and several fixing sections 242. When the weight block 30 is moved to the fixing section 242, a bolt 31 can be passed through the fixing section 242 and screwed into the weight block 30. The weight block 30 can be moved along the swinging plate 24 to adjust the position of the weight block 30. The closer to the central shaft 11 the weight block 30 is, the less the force necessary for swinging the swinging plate 24 is. Reversely, the farther from the central shaft 11 the weight block 30 is, the greater the force necessary for swinging the swinging plate 24 is.

Referring to FIG. 5, by means of the waist belt 19, the exerciser of the present invention can be tied on a user's waist with the swinging plate 24 locked on the fitting tube 21 by the bolt 28 screwed in the thread hole 23. The swinging plate 24 is perpendicular to the fitting tube 21. The weight block 30 has a certain weight so that due to gravity, the weight block 30 tends to move downward. The user's hands hold the handles 14 with certain strength. The foam materials 16 are leant against two sides of the user's waist to provide massaging effect for the waist. In order to revolve the swinging plate 24 and the weight block 30, the user must half-crouch to swing the swinging plate 24 with the weight block 30. At this time, the fitting tube 21 is rotated about the central shaft 11. When half-crouching, the user's legs must exert certain strength to support the user's own weight. Therefore, the present invention can be used to train the user's arms, waist and legs. In addition, by means of the above exercise, the foam materials 16 leant against two sides of the user's waist can provide massaging effect for the waist.

Referring to FIGS. 6 and 7, when not used, the bolt 28 is unscrewed and the swinging plate 24 is pivoted onto the fitting tube 21 in a horizontal state. Therefore, the exerciser of the present invention can be folded into a small volume to minify the storage room.

According to the above arrangement, the present invention has the following advantages:

• 1. In use of the present invention, the arms, waist and legs of a user can be well trained.
• 2. The foam material 16 and the inner tube 15 can be rotated about the oblique shaft 13 of the frame 10. Therefore, the foam material 16 can provide massaging effect for a user's waist.

The above embodiment is only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiment can be made without departing from the spirit of the present invention.
