Tri-wheel skating boot

Abstract

A tri-wheel skating boot, comprised of a hollow area formed at the bottom in the rear of the truck, a suspended support shaft frame extending forward from the rear of the truck, a laterally disposed shaft tube at the end of the support shaft frame pivoted to a wheel shaft with both ends connected to two rear wheels, a seat at the center above the shaft tube, a recessed trough in the rear truck, a hole at the bottom of the recessed trough to connect through the hollow area below, a connection block between the hole and the seat; a protrusion at the upper end of the connection block to lock it in position relatively to the hole; a spherical surface at the lower end of the connection block to hold against the seat, a screw hole at the top of the connection block; a convexity with a central hole formed in the rear of boot above the truck to be inserted into the recessed trough in the truck and secured with a bolt in the connection block for achieving proper deflection of the support shaft frame to compromise the inclination whenever the skater takes a turn.

I claim,  
     
         1 . A tri-wheel skating boot with a truck made of plastic material and a boot connected to an upper part of the truck, characterized by that: 
 the truck having formed a hollow area at the bottom in the rear and extending forward a suspended support shaft frame; a laterally disposed shaft tube being formed at one end of the support shaft frame; a seat being formed at the center of the upper side of the shaft tube; a recessed trough being formed on the rear of the truck; a hole being provided at the bottom of the recessed trough to connect through the hollow area below; a connection block being provided between the hole and the seat; a protrusion being provided at the upper end of the connection block to lock in position relatively to the hole; a spherical surface being provided at the lower end of the connection block to hold against the seat; a screw hole being provided at the top of the connection block;    a convexity having a center hole being provided in the rear of the boot to protrude toward the bottom;    the boot having its convexity in the rear inserted into the recessed trough in the rear of the truck; a bolt being directly penetrated through the hole and secured in the screw hole of the connection block; two wheels being respectively provided to both ends of the shaft tube of the support shaft frame pivoted to a wheel shaft; both rear wheels sliding on the ground to appropriately deflect the suspended support shaft frame when subject to the pressure exercised by the weight of the body of a skater taking a turn to help achieve a smooth and reliable turn by compromising the inclination created at taking the turn.
