Weight training sled with enhanced component force effect

Abstract

A weight training sled with enhanced component force effect is disclosed, the sled including: a main frame with first and second ends remote from each other; a push frame, erected at the first end of the main frame; an operating handle, erected at the second end; a resistance wheel, in a rotatable state, disposed at the first end and equipped with a damping structure for providing a damping effect to retard the rolling of the resistance wheel; two wheels, in a rotatable state, disposed at either side of the second end, allowing the main frame to be displaced by utilizing the rolling of each of the wheels and the resistance wheel; and wherein, the height of the first end of the main frame is lower than the height of the second end, relatively causing the second end to have an upward inclination angle θ which is between 3° and 30°.

I claim: 
     
         1 . A weight training sled with enhanced component force effect, comprising: a main frame comprising a first end and a second end remote from each other; a push frame, erected at the first end of the main frame; an operating handle erected at the second end of the main frame; a resistance wheel in a rotatable state, disposed at the first end and equipped with a damping structure for providing a damping effect to retard the rolling of the resistance wheel; two wheels in a rotatable state, disposed at either side of the second end, allowing the main frame to be displaced by utilizing the rolling of each of the wheels and the resistance wheel; and wherein, the height of the first end of the main frame is lower than the height of the second end, relatively causing the second end to have an upward inclination angle which is between 3° and 30°. 
     
     
         2 . The weight training sled with enhanced component force effect according to  claim 1 , wherein the main frame is further provided with a weight load holder that allows the user to load a weight member selectively. 
     
     
         3 . The weight training sled with enhanced component force effect according to  claim 1 , wherein the second end of the main frame is further provided with a pulling connection portion that allows for the assembly of a pulling member. 
     
     
         4 . The weight training sled with enhanced component force effect according to  claim 1 , wherein the operating handle comprises two Y-shaped handlebars in a spaced apart configuration. 
     
     
         5 . The weight training sled with enhanced component force effect according to  claim 1 , wherein the two wheels are of an omni-directional wheel type capable of free rotation.
