Embodiment Construction

[0013] The specific implementation will be described below in conjunction with the accompanying drawings. When the trainer does exercise on the treadmill, both feet are fixed on the both feet fixing device 9, and both hands hold the swing arm lever 19 of the swing arm device. When the first foot moves forward, the rear sheave 1 is driven to rotate by the back stay rope 2. Since the rear sheave 1 is connected with the resistance increasing device 12 through the axle, the first foot can be subjected to resistance when moving forward. . The structure of the resistance increasing device can be air pressure, hydraulic pressure, friction, gravity and the solid-liquid method of controlling the viscosity of the liquid with the strength of the current invented by the Hong Kong University of Science and Technology. In this figure, only the friction type is used. The structure of this method is the same as that of other methods. The structures are not complicated and will not be describ...

Abstract

The invention provides a load type treadmill, which is provided with drag devices on the basis of the prior treadmill for training in the state of increasing resistance. The load type treadmill consists of a pair of swinging arm devices and a group of two feet fixing devices. When a sporter pushes and pulls swinging arm rods connected with a drag device through a gear, a rack and a connecting rod, two hands can meet resistance when moving forwards or backwards, and the resistance can be adjusted. Besides, when the two feet fixing devices are applied with force to move forwards and backwards, the two feet fixing devices can drive a cable pulley to be connected with the drag device through a hauling cable; therefore, two feet can meet resistance when moving forwards and backwards, and the resistance can be adjusted; and at the same time, the hauling rope not applied with force can be automatically withdrawn by the cable pulley provided with an overrunning coupler and a torsion spring. In order to prevent the body from moving forwards and backwards, the treadmill is also provided with a body positioning device. Moreover, the height, tilt angle and level angle of the swinging arm devices can be adjusted according to self condition of the sporter. If all the drag devices and resistance are unloaded, the load type treadmill can be taken as a common treadmill for use.

Description

technical field [0001] The invention relates to a loading treadmill. Background technique [0002] Existing treadmills sold on the market and the treadmills retrieved by myself on the patent network, they all make the sportsman do free exercise on the treadmill, and some use the inclination angle of the pedals and the ground to reduce the resistance and even use electric power to move the treadmill. Reduced drag. They are difficult to meet the technical and strength training requirements of professionals. [0003] In the patent application No. 03249275.8 on November 23, 2001, which I retrieved on the China Patent Network, I disclosed a "swing arm structure of a treadmill". The double-arm swing curve of running without adding resistance. Contents of the invention [0004] The invention provides a load-type treadmill capable of enabling athletes to perform running training under the state of increasing resistance. [0005] In order to solve the above-mentioned technical ...
