Structure of inline skates

Abstract

The present invention relates generally to an improved structure of inline skates, which provides a cushion, a wheel with a gearwheel on its side, and a pawl assembly. By pressing down the weight, the wheel with gearwheel on its side occludes the pawl assembly, which stops the wheel with gearwheel on its side from rolling one-wayly. Thereby, the improved structure of inline skates is more ergonomic and exercise injuries can be prevented. In addition, a brake is provided for providing shock absorption and more powerful acceleration. Besides, automatic support upright is also provided for avoiding tumbles.

1 . An improved structure of inline skates, comprising:
 a boot;   a base, securing at the bottom of the boot, comprising one or more connection plates, and two side plates being adapted on both sides of the bottom of the connection plate, respectively with a plurality of pivotal holes thereon;   a wheel set, comprising a plurality of wheels, a front wheel, and a rear wheel, and the plurality of wheels, the front wheel, and the rear wheel being pivoted on the side plates;   one or more one-way roll stop devices, comprising a gearwheel and a pawl assembly, the gearwheel securing on the side of the front wheel or the rear wheel, the pawl assembly securing on the side plate, and the gearwheel and the pawl assembly corresponding to positions of each other; and   one or more cushions, one end thereof being adapted on the side plate corresponding to the front wheel or the rear wheel, and the other end thereof connecting to the front wheel or the rear wheel and the gearwheel through a screw bolt assembly;   wherein when the base is pressed, the cushion is compressed and drives the gearwheel to contact with the pawl assembly for stopping the front wheel or the rear wheel from rolling one-wayly.   
   
   
       2 . The improved structure of inline skates of  claim 1 , wherein the cushion includes a sliding block and sleeve assembly, a spring, and an adjustment shaft, the sliding block and sleeve assembly connecting with the front wheel or the rear wheel and the gearwheel through the screw and bolt assembly, the sliding block and sleeve assembly including a sleeve with a trench adapted for accommodating the spring and the adjustment shaft, and the top end of the adjustment shaft securing at the bottom of the connection plate. 
   
   
       3 . The improved structure of inline skates of  claim 2 , wherein the side plate connects pivotally with the front wheel or the rear wheel through a long pivotal bore, the sliding block and sleeve assembly further including a sliding block, the sliding block being a long block corresponding to the long pivotal bore with a shorter length, and the sliding block being able to inset in the long pivotal bore. 
   
   
       4 . The improved structure of inline skates of  claim 2 , wherein the adjustment shaft has threads thereon with one or more nuts, and the spring is confined between the trench and the nuts for adjusting the compression force of the spring. 
   
   
       5 . An improved structure of inline skates, comprising:
 a boot;   a base, securing at the bottom of the boot, comprising one or more connection plates, and two side plates being adapted on both sides of the bottom of the connection plate, respectively with a plurality of pivotal holes thereon;   a wheel set, comprising a plurality of wheels and a front wheel, the plurality of wheels being pivoted on the side plates, and the front wheel connecting with the plurality of wheels through a front side plate;   one or more one-way roll stop devices, comprising a gearwheel and a pawl assembly, the gearwheel securing on the side of the front wheel, the pawl assembly securing on the side plate, and the gearwheel and the pawl assembly corresponding to positions of each other; and   one or more cushions, one end thereof being adapted on the side plate corresponding to the front wheel, and the other end thereof connecting to the front wheel and the gearwheel through a screw bolt assembly;   wherein when the base is pressed, the cushion is compressed and drives the gearwheel to contact with the pawl assembly for stopping the front wheel from rolling one-wayly.   
   
   
       6 . An improved structure of inline skates, comprising:
 a boot;   a base, securing at the bottom of the boot, comprising one or more connection plates, and two side plates being adapted on both sides of the bottom of the connection plate, respectively with a plurality of pivotal holes thereon;   a wheel set, comprising a plurality of wheels and a front wheel, the plurality of wheels being pivoted on the side plates, and the front wheel connecting with the plurality of wheels through a front side plate;   one or more one-way roll stop devices, comprising a side gearwheel and a side pawl assembly, the side gearwheel securing inside of the front wheel, the side pawl assembly securing on the front side plate, and the side gearwheel and the side pawl assembly corresponding to positions of each other;   one or more cushions, one end thereof being adapted on the side plate corresponding to the front wheel, and the other end thereof connecting to the front wheel, the front side plate, and the side gearwheel through a screw bolt assembly; and   one or more driving apparatus, adapted on the side plate;   wherein when the base is pressed downwards, the cushion is compressed and drives the driving apparatus to press the side pawl assembly to occlude the side gearwheel for stopping the front wheel from rolling one-wayly.   
   
   
       7 . The improved structure of inline skates of  claim 6 , wherein the driving apparatus has a contact inclined plane. 
   
   
       8 . An improved structure of inline skates, comprising:
 a boot;   a base, securing at the bottom of the boot;   a wheel set, comprising a plurality of wheels and a front wheel;   one or more cushions, connecting to the front wheel and the base; and one or more one-way roll stop devices, being adapted at the location corresponding to the front wheel, and by accompanying the cushion making the one-way roll stop device in an occlusion and cease-rolling status or a free-sliding and maintain-rolling status;   wherein when the base is pressed while the front wheel rolling backwards, the cushion is compressed and drives the one-way roll stop device for stopping the front wheel from rolling one-wayly.
