Waist twisting station

A waist twisting station includes a base, a rotating unit for waist twisting, and at least one spring to generate resistance force. The rotating unit has a hoop linked with a spring, which can be pushed away by user's body movement. The inside layer of the hoop has a row of massage balls so that the body movement can exercise the waist and lags as well as receive body massage at the same time to accelerate calorie burning. In addition to the waist twisting hoop, a handle bar with or without spring connected to the base can give user a unique whole body exercise experience.

RELATED APPLICATIONS

BACKGROUND OF THE INVENTION

The invention relates to fitness equipment, particularly waist-training machine for a user to twist his or her waist in the same way as a hula-hoop but with much more resistance force, at the same time massaging the waist.

Many kinds of fitting equipment are widely used nowadays, for twisting the waist and buttocks. Simjian (U.S. Pat. No. 3,945,637) and Chang (U.S. Pat. No. 6,918,856) tried to invent the waist massage and waist exercise machines. Traditional hula-hoops have been used for twisting the waist and the buttocks for acquiring body training owing to its soft smooth movement, very prevalent among consumers. However, the traditional hula-hoops have some disadvantages. 1. A person should have certain experience or technique, or the person will be unable to maneuver it smoothly on the waist. 2. The traditional hula-hoop doesn't have enough resistant force on user's waist; therefore take longer time to burn calories. 3. In starting to move around the traditional hula-hoop on the waist, a person is prone to harm the waist, especially for the old. 4. The traditional hula-hoop can't efficiently massage the waist or buttocks to help burning stomach and waist fat.

In current invention, a waist-twisting station includes a base, a rotating unit (waist twisting hoop) connected to at least one spring leg, and a handle bar with or without spring(s). For the one spring leg example, the spring axis 16 and the waist twisting hoop axis are overlapped. The spring can be coil spring or a piece of spring material column. The base has a foot board on it, the vertical handle bar is connected to the front part of the base, and the waist twisting hoop is connected to the base by a vertical spring and connection bar(s). The waist twisting hoop has a row of rotatable balls or rollers on the inner lay. The height of the waist twisting hoop and handle bar can be adjusted to higher and lower position to fit user's waist and hands.

The waist twisting hoop is pushed by the user in a circular around the vertical spring, provided with massage rollers (balls) in its inner surface so that a user entering the waist twist hoop may do circular (or twisting) action and receive massage action synchronously, obtaining the effect of waist twisting exercise and slimming at the same time. The massage will help burn the fat.

SUMMARY OF THE INVENTION

This invention relates to a waist twisting station with spring to offer resistant force. The rotatable balls or rollers on the rotating unit (waist twisting hoop) offer smooth movement of user's body along the hoop and give massage to user at the same time. The user twists the waist against the hoop and receives the spring's force and also receives massage action from the balls or rollers at the same time. This exercise can slim the body and build waist and abdomen mussel. Also the waist twisting station can be used as arm exercise equipment by bending the spring connected to the handle bar.

DETAILED DESCRIPTION OF THE INVENTION

A preferred embodiment of a waist twisting station in the present invention, as shown inFIGS. 1-4, includes a base1, a waist twisting hoop30, a foot board5, a main spring10, a spring legs15and a spring handle bar55with handle bar spring50. The main spring10has an axis passing through the center of the main spring10. The waist twisting hoop also has an axis passing through the center of the waist twisting hoop. The axis of the main spring10and the axis of the waist twisting hoop30are substantially overlapped to make the resistance force the same when push against the waist twisting hoop30in any direction. The main spring can be coil spring or a piece of spring steel column or other spring material column.

The leg15has an adjustable sleeve with adjust knob20to adjust the height of the waist twisting hoop30. Also the waist twisting hoop30can be moved in horizontal direction via T-link25and the adjust knob35. The handle bar55also has an adjustable sleeve with adjust knob53to adjust the handle bar height as well as the resistance force. The vertical bar40and48are linked by the adjust knob45.

The waist twisting hoop30has multiple holes to hold a row of rotating balls65/70. Also, the waist twist hoop30with hinge link80can be opened and closed using a pin75as showed inFIG. 4. Massage ball70was fixed inside the ball holder65and can free rotate inside the ball holder65as showed inFIG. 5.

The handle bars55and60have an adjustable sleeve with adjust knob53, vertical bars51and48are connected by spring50.

The user stands on the foot board and close the waist twisting hoop30to lock his/her waist in it, put hands on the handle bar horizontal support arm55, then rotate his/her waist to move the waist twisting hoop30from side to side or rotate in circular. When the waist twisting hoop30is pushed aside, the force from the main spring10will push the waist twisting hoop30against user's waist. The massage ball70can rotate while the waist moves around the waist twisting hoop30to give waist massage and generate less friction on waist during the waist movement.

The waist twisting hoop comes with different diameter to fit user's waist. The main spring10and handle bar spring50come with different strength to fit different user's need.

Handle bar55and60can also be used to exercise user's arms by pushing, pulling, side bending, and rotating around the axis. This waist twisting station is good for waist, hip, leg, and arm exercise.

This invention can have at least following embodiments:1. The waist twisting hoop can have one or more than one spring(s) attached on it;2. The waist twisting hoop can have a hoop only or can have rotating balls or other rollers on the hoop inner circle to allow smooth body movement and generate massage function on user's body;3. This waist twist station can have handle bar with spring, handle bar without spring, or even without handle bar;4. This waist twist station can have spring handle bar along without waist twisting hoop, this is therefore the arm exercise station.
