Abstract: A sun visor which rotates and slides and is capable of covering top horizontal and slanted parts of a front windshield or a side window of an automobile or a vehicle whenever it is desirable to do so. The rotating motion through a range of angles is facilitated by the rotation of a plate which sits loosly inside the visor. The plate has a clamp part which fits tight enough yet can rotate around the rod axle. This invention also automates the function of the visor in such a way that the motion into an appropriate position can be accomplished (a) manually, (b) by pressing conveniently located buttons connected to the car's electric system and to motors associated with the visors, and (c) by sun striking photocells placed at representative locations around top parts of the front windshield and the front side windows.

Abstract: This invention introduces a single sun shade for a windshield, and a double sun shade for a side window of an automobile. The sun shades are capable of independently and simultaneously covering top adjacent parts of a windshield and a side window, whenever it is desirable to do so. A side window typically has a trapezoidal shape which is a composite of rectangular and triangular parts. The double shade also has a rectangular part and a triangular part and is capable of covering a top part, a corner, and a slanted part of a side window. The motions of the shades can also be actuated by electric motors.

Abstract: This invention introduces sun visors each restricted to cover a side window, or cover a windshield of an automobile. Each visor is mounted to a top part of an automobile by a single hinge and can rotate between a top stored position and a lowered used position. Each visor has a visor plate along one of its sides mounted to a plate of the hinge in such a way as to make it easy to slide the visor in a horizontal direction whenever it is desirable to do so.

Abstract: Sun visors for independently and possibly simultaneously covering parts of the top of one or both of the front windshield and a front side window of an automobile whenever it is desirable to do so. Sun visors can also cover top parts of other windows of an automobile. The visors may be attached to the automobile by different types of hinge mechanisms. This invention also automates the function of some visors in such a way that the motion of a visor into the appropriate positon can be accomplished (a) manually, (b) by pressing conveniently located buttons connected to the car's electric system and to motors associated with the visors, and (c) by sun rays striking photocells placed at representative locations around top parts of the front windshield and the front side windows.

Abstract: A pair of sun visors for covering parts of both a front windshield and a front side window of an automobile. The visors may be attached to the automobile with cylindrical rods associated with bracket units, several different types of hinge mechanisms or a clamp and plate arrangement. The visors may also be actuated by electric motors for rotation and/or pneumatic or hydraulic elements for sliding the visors relative to the rods upon which they are mounted. This invention also automates the function of some visors in such a way that the motion of a visor into the appropriate position can be accmplished (a) manually, (b) by pressing conveniently located buttons connected to the car's electric system and to motors associated with the visors, and (c) by sun rays striking photcells placed at representative locations around top parts of the front windshield and the front side windows. Shades are also introduced in place of, or in conjunction with visors.

Abstract: An ice skateboard has front and rear trucks with horizontal axles attached thereto for pivotal steering movement of the axles in response to tilting of the skateboard. Each of the horizontal axles has a pair of runner blades attached thereto. An auxiliary blade assembly is attached to each side of the skateboard between the front and rear trucks and in tandem with the runner blades attached to the axles. Each of the auxilary blade assemblies include a mounting arrangement which permits pivotal movement of the auxiliary blade relative to the longitudinal axis of the skateboard.

Abstract: This invention introduces several variations of Regular Polyhedron Puzzles which are improvements, generalizations and extensions to "Rubik's" Cube, "Pyraminx" tetrahedron and the class of puzzles given in the reference cited. The preferred embodiments include octahedron and icosahedron cubic puzzles. The distinguishing features and examples of the puzzles are briefly described. Each of the puzzles is comprised of component pieces which are joined and held together by an appropriate means to form a desired overall regular polyhedron shape having at least eight (8) plane faces. The external surfaces of each puzzle are to be assigned a unique combination of colors or pictures. The mechanism of motion makes it possible to rotate the individual component pieces of a puzzle in groups around lines joining the puzzle center and the puzzle vertices. Various possible rotations (twists and turns) result in mixing up the surface configurations.

Abstract: Two distinct dodecahedron cubic puzzles, one a Rhombic Dodecahedron Puzzle having twelve diamond faces and the other a Regular Dodecahedron Puzzle having twelve pentagon faces. The ideas involved can be readily applied to other puzzles having newer shapes such as the rhombic triacontahedron. The distinguishing features of these puzzles are briefly described. Each of the puzzles is comprised of component pieces which are joined and held together by an appropriate means. The external surfaces of each puzzle are to be assigned a unique combination of colors or pictures or monthly calendars. The mechanism of motion makes it possible to rotate the individual component pieces of a puzzle in groups around lines joining the puzzle center and the puzzle vertices. Various possible rotations (twists and turns) result in mixing up the surface configurations.

Abstract: This invention extends and generalizes a family of N-pronged (N=3,4,5,6, . . . ) star-based right prism puzzles given in the references cited. Here the overall shapes of the puzzles and the shapes of their various component structures need no longer be right prisms. Futhermore, each prong can have 3L component structures where L is no longer restricted to be one (L=1). Each N-pronged puzzle is comprised of three layers of component structures, each group of component structures in a layer can rotate together around a principal axis of the puzzle. The component structures in a prong of a puzzle appear in sets, each set is comprised of three component structures which can rotate jointly relative to all other component structures in a plane parallel to the principal axis of the puzzle. Each surface of a puzzle is to be initially assigned a unique color or picture. Various possible rotations (twists and turns) result in mixing up the surface configurations.

Abstract: This invention introduces several new Polyhedral Puzzles based on variations and extensions to the 2.times.2.times.2 cube. Spherical and shell analogue puzzles are also disclosed. These puzzles are of "Rubik's" Cube and "Pyraminx" tetrahedron class (Rubik's Cube is a registered trademark of Ideal Toy Corporation, "Pyraminx" is a registered trademark of Tomy Corporation). Main features and examples of the puzzles are briefly described. Each of the puzzles is comprised of component pieces which are joined and held together by an appropriate mechanism to form a desired overall shape. Each surface of a puzzle is to be assigned a unique color or picture. The mechanism of motion makes it possible to rotate the individual component pieces of a puzzle in groups in planes and around axes emanating from the center of the puzzle. Various possible rotations (twists and turns) result in mixing up the surface configurations.

Abstract: This invention introduces a family of N-pronged (N=3,4,5,6, . . . ) star-based right prism puzzles which generalizes puzzles of the "Rubik's" Cube and "Pyraminx" tetrahedron class and of the class of puzzles given in the reference cited. Main features and examples of the puzzles are briefly described. Each N-pronged star-based right prism puzzle is comprised of three layers of predominantly right prism component pieces; each layer is bounded between two planes parallel to the bases of said star-based right prism. The middle layer of component pieces is comprised of a core central part surrounded by N right prism edge component pieces. The core central part is comprised of rod axes of rotation emanating from the center of each puzzle, N rod axes of rotation uniformly distributed in a plane parallel to the bases of the right prism puzzle and two rod axes of rotation pointing in opposite directions orthogonal to the bases of the right prism puzzle.
