发明名称 Penmanship aid
摘要 A penmanship aid includes a base portion that has an upper surface, a lower surface, a first lateral side, a second lateral side, a front side and a back side. Each of a pair of supports is hingedly coupled to the base portion. The supports are each positioned adjacent to one of the front and back sides such that each of the supports generally extends upwardly from a respective one of the front and back sides. Each of a pair of biasing members is coupled to one of the supports such that the upper ends are biased toward each other. A ball bearing is rotatably mounted in the lower surface such that the ball bearing extends through a plane of the lower surface. An edge of a hand may be positioned adjacent to the upper surface such that each of the supports is abutting opposite sides of the hand.
