Abstract

A magnet has a north pole and a south pole. The magnetic force of the north pole of a magnet attracts the south pole of another magnet. The magnetic force of the north pole of a magnet repels the north pole of other magnet. The magnet exercise tube uses the nature of the attractive force and the repelling force of the magnet to create a resistance for exercising muscles. A magnet exercise tube consists of one small inner magnet tube, an in-between separation plastic tube and one larger outer magnet tube to create the resistance for exercising muscles. The larger the magnet exercise tube is, the greater the resistance will be created.

Description

BACKGROUND OF THE INVENTION

Most of the exercise devises use the mechanical force, which is created by weights, rubber bands or spring coils, to provide the resistive force. The present-invented magnetic exercise tube uses the magnetic force to provide resistance for exercise. A magnet has one north pole and one south pole. The north pole of a magnet repels the north pole of another magnet. The north pole of a magnet attracts the south pole of another magnet. By using the nature of attractive force and repelling force of a magnet, we can build a magnet exercise tube.

BRIEF DESCRIPTION OF THE INVENTION

The magnet exercise tube consists of one large outer magnet tube, one small inner magnet tube and an in-between plastic tube. Each magnet tube consists of numerous O-ring shaped magnets and a plastic tube. The O-ring shaped magnets are arranged and placed at an equal distance in each plastic tube. The in-between plastic tube is fixed tightly inside the large outer magnet tube. The small inner magnet tube can slide loosely inside the in-between plastic tube. When the small inner magnet tube is inserted into the in-between plastic tube, a resistive force will be created because of the attractive force or repelling force between the O-ring shaped magnets of the small inner magnet tube and the large outer magnet tube. By using this resistive force, one can exercise musles.

DETAILED DESCRIPTION OF THE INVENTION

Reffering to the drawings in detail wherein like numerals designate like parts, a [0007] magnet exercise tube 5 consists of a large outer magnet tube 6 and a small inner magnet tube 7 and an in-between separation tube 8, as illustrated in FIG. 1. There are numerous large O-ring shaped magnets 9 which are arranged at an equal distance 11 in the large outer magnet tube 6, as illustrated in FIG. 2. There are also numerous small O-ring shaped magnets 10 which are arranged at an equal distance 11, as it is in the large outer magnet tube 6, in the small inner magnet tube 7, as illustrated in FIG. 4. The in-between separation tube 8 is fixed tightly inside the large outer magnet tube 6, as illustrated in FIGS. 1 and 3. The central chamber 12 of the in-between separation tube 8 is larger than small inner magnet tube 7, as illustrated in FIGS. 1, 3 and 4. The small inner magnet tube 7 can be inserted loosely into the chamber 12 of the in-between separation tube 8 and can be slid smoothly inside the chamber 12, as illustrated in FIGS. 1, 3 and 4.
