Abstract

A fitness treadmill consists mainly of a base, two sliding rail sets and two stepping boards; each of the rail set is formed by two rails in symmetrical shape; each rail has an upper rail strip assembled on the lower rail strip and the upper and lower rail strips are implemented with one or more than one guiding section based on the stepping board moving method; whereas the two stepping boards are respectively installed with front rollers and rear rollers on the two sides for each of the stepping board set to be assembled to each sliding rail set so that the rear rollers are pressed against the upper rail strip and the front rollers are pressed against the lower rail strip for the front and rear rollers to roll along the upper and lower rails and guiding section.

Claims

1. A fitness treadmill with characteristics comprising a base, two sliding rail set, and two stepping boards, wherein:

a base, which is the assembly for stabilizing treadmill and providing two sliding rail set installed on its top;

two sliding rail set, where in each sliding rail consists of two rail in symmetrical shape;

each rail consists of an upper rail assembled on the lower rail, with a gap formed between the upper and lower rails;

said upper rail is bent with one or more than one guiding section for guiding stepping board sliding angle;

said lower rail is also bent with one or more than one guiding section for guiding stepping board sliding angle;

with this the two rails constitute a symmetrical rail set for the two rail set to be assembled on the base;

two stepping board, wherein each is a board installed with two front roller and two rear roller;

the two stepping boards are assembled on the two sliding rail set so that the two rear roller pressed against on the upper rail strip forming connection, whereas the two front rollers pressed against the lower rail strip forming connection;

the front and rear rollers could roll on the respective upper and lower rail strips for each stepping board to generate variations in angle during sliding movement.

2. The fitness treadmill claimed in 1, wherein the said base consists of a front base and a rear base;

the front base constitutes a lateral strip;

the each of two sides of the lateral strip is installed with a pivoting board;

the inner side of each pivoting board and the center of the lateral strip is installed with a rail strip fixture which allows the upper rail connects to the front of the lower rail. And the rear base also constitutes with a lateral strip;

the lateral strip is installed with several protruding plates for the upper trail strip to connect to the rear end of the lower trail strip.

3. The fitness treadmill claimed in 2, wherein the back of the lateral strip of the said front base is installed with two pulley seats corresponding to two stepping boards;

each pulley seat is installed with a vertical pulley and horizontal pulley. And a piece of rope is installed through the two pulley seats between the vertical and horizontal pulleys so that the two free ends of the pulling rope extends to each stepping board for connection.

4. The fitness treadmill claimed in 2, wherein the said rail strip fixture is in plate shape and forming U-shape fixing section at the top as the fixing part for the connection of upper rail strip and lower rail strip.

5. The fitness treadmill claimed in 1, wherein the shape of the guiding section of the said upper rail is to extend the front section of the upper rail strip forming a curve shape at the top, and the foremost end extends downward and bent into guiding section in V-shape, whereas the rear end of the upper rail strip is extending horizontally.

6. The fitness treadmill claimed in 1, wherein the guiding section of the said lower trail strip is the front section of the lower rail strip extending upward in curve shape.

7. The fitness treadmill claimed in 1, wherein the said upper rail is installed with the first guiding section and the second guiding section;

the shape of the first guiding section is to bend the front section of the upper rail strip upward in curve shape whereas the shape of the second guiding section is to bend the rear section of the upper rail strip upward in curve shape.

8. The fitness treadmill claimed in 1, wherein the front section of the said lower rail is installed with a front stopping part that uses the front and back stopping-parts as the stopping point for the roller'"'"'s movement.

9. The fitness treadmill claimed in 1, wherein the bottom of each of the said stepping board is installed with a hooking strip for hooking the bottom of the lower rail strip.

10. The fitness treadmill claimed in 1, wherein the two front rollers and the two rear rollers respectively are connected with an axis for the connection of axis and stepping board to form rotating state.

11. The fitness treadmill claimed in 1, wherein the two handrails can be installed;

each handrail can be made of steel pipe comprising a holding section at the bending part of the upper section and a pivoting section near the bottom end so that the pivoting sections of the two handrails connect to the pivoting boards on the two sides of the front base to become rotating form, and near the pivoting section a fast rotating fixture is installed for the handrail to be fixed at proper angle; and

between the selected locations of the symmetrical parts of the two handrails a lateral rod is connected;

the body of the lateral rod is installed with two pivoting seats for connecting to the rocking pole described below.

12. The fitness treadmill claimed in 1, wherein two rocking poles are installed;

each of the rocking poles is long pole of steel pipe or other pipe material;

the body of the rocking pole is installed with a pivoting part for the pivoting part to connect to the pivoting seat of the above stated lateral rod to form swinging state;

the upper section of the rocking pole is a holding section, whereas near the bottom end of each is installed with a metallic pulling strip for one end of the pulling strip to pivot to the rocking pole and the other end pivot to the bottom of the stepping board will cause the two rocking poles and the two stepping boards to move jointly. When the hand is holding the holding section of rocking pole and the foot is stepping on the board for sliding movement, the arm swinging effect during running can be achieved.
