Abstract

A skate having simplified accelerating device generally includes a truck having a plurality of rollers rotationally mounted thereunder. A boot is pivotally installed to the front portion of the truck by means of a shaft pin. The rear portion of the truck is provided with a mounting socket which has an opening at the top and a threaded portion at bottom. The threaded portion can be readily sealed by a plug having a dowel thereof. The boot is provided with a mounting boss corresponding to the mounting socket of the truck. A circular guiding post having a bottom flange is slidably inserted into the mounting socket of the truck. The top of the circular guiding post is fixedly connected to the mounting boss of the boot. The outer diameter of the flange of the circular guiding post is larger than the upper opening of the socket such that the circular guiding post is limited within the socket. A spring member having a longer length than the circular guiding post is disposed and inserted within the circular guiding post and both ends of the spring member are biased by the mounting boss and the plug disposed at bottom the socket of the truck. By this arrangement, the boot is biased upward respect to the truck by the extension of the compressed spring member. When the user lifts his/her leg, the truck is still contacted with the ground without floating above the ground, accordingly, the weight of the truck will not become a heavy load to the user when the leg is lifted while the tip of the truck may still be used to kick back to push the body forward. As a result, the in-line skate can be quickly accelerated with less energy while the speed is increased.
