In line roller skate with shock absorbent suspension

Abstract

An in line roller skate comprises a platform in horizontal plane and side brackets secured to underside of horizontal platform in vertical plane opposing each other and straddling at least one pair of extension arm pivotally arranged in vertical plane and contained about non rotational center axle in horizontal plane by a lot of spacer element to be contiguous to extension arm. Pair of extension arm is configured of singular extension arm coaxial affixed and opposed to each other in mirror image that distal end of at least one extension arm is of forked position from distal end of opposing extension arm. Distal end of extension arm has an axle fixated in non-rotational fashion with skating wheel pivotally affixed in a vertical plane thereof. Extension arm is encircling an elastic element being confined and arranged to allow extension arm to rotate about center axis within a certain range and quadrant of a full circle of which rotation can also be in tandem whereby opposing extension arm is fixated to each other and sharing a skating wheel attached to axle shaft at distal end of pair of extension arm. It is also contemplated that an in line roller skate can be converted quickly into a 2 wheel and 4 wheel inline roller skate depending on the preference of the in line roller skate rider.

1 . An inline roller skate comprises a platform in horizontal plane having foot wear attached to upper side thereof with at two side bracket in vertical plane secured to under side of said platform opposing each other and straddling at least one paired extension arm pivotally mounted and contained about non pivotal center axis in horizontal plane with said paired extension arm being two singular extension arm opposed to each other in mirror image so that distal end of at least one said extension arm is of forked position in vertical plane from distal end of said opposing extension arm, and having at axle fixated to said distal end in horizontal plane with a skating wheel affixed to and contained in vertical plane about said axle with said extension arm encircling a torsion spring thereof confined to allow said extension arm to pivot about said center axis in forward motion and opposite direction from each other.  
   
   
       2 . The apparatus of  claim 1  comprises said center axle being affixed in non pivotal fashion to each other opposing side bracket at one extremity of said axle and respectively opposite extremity thereof.  
   
   
       3 . The apparatus of  claim 1  whereas said extension arm comprises a hub section with said torsion spring confined within hub section of said extension arm wherein said torsion spring is having a right angle extension at opposite ends providing containment of said torsion spring with through hole in said hub section for said right angle extension and with a through hole in said side bracket for said right angle extension of opposite end of said torsion spring.  
   
   
       4 . The apparatus of  claim 3  whereas said torsion spring comprises a multi coil configuration and with said right angle extension to be in coaxial alignment with center axis thereof, and at least one through hole to be of elongated configuration in vertical plane.  
   
   
       5 . The apparatus of  claim 1  whereas said pivotal containment of said extension about said center axle further comprises lot of spacer element sized in cross sectional distance to be contiguous to said extension arm.  
   
   
       6 . The apparatus of  claim 3  whereas said extension arm further comprises a range of pivotal movement confined by said torsion spring depending on location of said through hole in said hub section of said extension arm.
