Abstract: A child's combination toy comprising a bicycle, or tricycle, to the frame of which a seated doll is attached in front of the handlebars. The doll is seated with its hands grasping a miniature set of handlebars and its feet resting on a miniature set of pedals which are coupled to the cycle's front wheel by a gearing and friction-drive arrangement. The legs of the doll are flexible so that they are moved by means of the pedal action in correspondence with the action of the legs of the cycle's rider. The doll also turns in correspondence with the turning of the cycle's handlebars. The actions of the doll cause it to appear to be operating the cycle in conjunction with the actual operator.

Abstract: There is disclosed an image orientation and projection system for use with stereoscopic viewing and projection systems.The preferred embodiment utilizes a stereoscopic viewing system of one or two prisms, preferably each having a plano face and an opposite face bearing a plurality of spaced-apart, straight and parallel V-grooves. Reflective surfaces are positioned in relation to said prisms to permit the employment of left and right stereoscopic images in their normal (left - right) and unreversed orientation to each other.

Abstract: A pivotal jumping stick with the handlebars and footrest connected together and pivoted at their centers to permit the user to maintain his balance on uneven terrain. While in motion, a pin slides vertically in a slot formed in the impacting rod, counteracting the inherent twisting force of the spring mechanism, and allowing the user to accurately steer the device.

Abstract: A board game includes an upright playing surface representative of a mountain having trails or paths thereon with openings for releasably receiving playing pieces, there being missiles or other hazards slidably or movably related to the mountain and which are adapted to strike the playing pieces to physically knock them off of the mountain.

Abstract: There is disclosed a stereoscopic viewing system utilizing one or two prisms to direct the line of sight from a viewer's eyes to each of a pair of stereoscopic images. The single lens sytem employs different occluded angles between the prism faces and the facing image planes to avoid lateral distortion of the images. In the preferred embodiment, the prisms have a plano face and an opposite face bearing a plurality of equally-spaced, straight and parallel V-grooves, forming a plurality of equally-spaced, longitudinal triangular prisms therebetween. The preferred viewing system employs, in the simplest embodiment, one of these prisms mounted with its grooved face at an occluded angle of from 40.degree. to about 60.degree. to one of a pair of stereoscopic images. The second stereoscopic image is mounted on a planar imaging surface at an occluded angle of from 2.degree. to about 15.degree. to the plano face of the prism.
