ABSTRACT:
Disclosed is a height-adjustable brake mechanism for roller skates, mainly including a fixing member, a movable member fitly and adjustably covered over the fixing member, a fixing bolt member for adjustably attaching the movable member to the fixing member, and a brake block attached to the movable member at a proper position and height for safely braking the roller skates when necessary. The fixing and the movable members have upward arched curved bodies and are provided with toothed top surfaces and toothed lower edges, respectively, which mesh with each other to allow the two members to engage with each other in a firm and finely adjustable manner. Teeth on the toothed portions of the two members are designed to have a certain declination that permits the movable member to be pushed backward relative to the fixing member only. To adjust the position of the movable member relative to the fixing member, just loosen the fixing bolt member to disengage it from a threaded hole on the fixing member without being moved out of the movable member, push the movable member to a desired lower position, and then tighten the fixing bolt member against the fixing member again. The brake block attached to the bottom of the movable member can therefore be lowered for further use when it is worn and becomes shortened.
