Abstract

Abstract A skate construction with pre-set buffering, shock-absorbing and the topogrphy compliance functions essentially composed of a footwear, a sole plate, a set of suspended support arms, a set of buffer wheels and a stop fixed block placed on the terminal portion of the sole plate, which is mainly characterized in that by employing a design of a low resistance rubber inflatable tire in combination with a single hub type support, a skate construction is given for keeping stable and smooth when the skate is used on lawns, concrete, unleveled or asphalt pavements.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 252 words
A skate having buffering, shock-absorbing and topographical complying functions comprising: a footwear, a sole plate having atop side and a bottom side, wherein the footwear is firmly affixed to the top side of the sole plate, a stop block affixed to the heel portion of the sole plate, which stop block is capable of reaching the ground during use, a single hub suspended from the bottom side of the sole plate comprising a plurality of spaced suspended support arms, wherein each suspended support arm is made of a tough material having bending resilience and is in the form of a bow bending to one side of said skate forming an upper bend and a lower bend, a reinforcing rib connecting the upper bend of each support arm to the sole plate to reinforce the upward bending resistance of each support arm, a horizontal axle hole at the lower bend of each support arm, a plurality of buffer wheels, wherein each buffer wheel is connected to the sole plate solely by a single support arm pivotally coupled to only one side of each wheel at the axle hole via a ball bearing, each buffer wheel comprising a hub of rigid material and a ring provided with an air valve of soft material at a proper position to provide an air pathway for an inflatable tire positioned on the wheel ring; whereby the skate may be used on various terrains, including lawns, concrete pavements and unlevelled ground, and still exhibit buffering and shock-absorbing properties.
Claim 2
Dependent Claim 252 words
A skate having buffering, shock-absorbing and topographical complying functions comprising: a footwear, a sole plate having atop side and a bottom side, wherein the footwear is firmly affixed to the top side of the sole plate, a stop block affixed to the heel portion of the sole plate, which stop block is capable of reaching the ground during use, a single hub suspended from the bottom side of the sole plate comprising a plurality of spaced suspended support arms, wherein each suspended support arm is made of a tough material having bending resilience and is in the form of a bow bending to one side of said skate forming an upper bend and a lower bend, a reinforcing rib connecting the upper bend of each support arm to the sole plate to reinforce the upward bending resistance of each support arm, a horizontal axle hole at the lower bend of each support arm, a plurality of buffer wheels, wherein each buffer wheel is connected to the sole plate solely by a single support arm pivotally coupled to only one side of each wheel at the axle hole via a ball bearing, each buffer wheel comprising a hub of rigid material and a ring provided with an air valve of soft material at a proper position to provide an air pathway for an inflatable tire positioned on the wheel ring; whereby the skate may be used on various terrains, including lawns, concrete pavements and unlevelled ground, and still exhibit buffering and shock-absorbing properties.
Claim 3
Dependent Claim 21 words
A skate according to claim 1, wherein the suspended support arms are screwed to the bottom side of the sole plate.
Claim 4
Dependent Claim 25 words
A skate according to claim 1, wherein each wheel ring is penetrated with several conduit holes on a lateral surface to improve stability in motion.
