Abstract
Abstract A two dimensional logical toy comprises a frame structure having a slide passage in which a slide plate is slidably mounted and on an apertured surface of which a plurality of parallel grooves are formed together with a single transverse groove, a lift including an elongated pedestal slidably and rotatably mounted within the aperture in said slide plate and provided with a platform on one end in which two sets of parrallel grooves are formed, one set of grooves being normally disposed in alignment with the parallel grooves formed in the slide plate and the other set of grooves being transverse thereto, said lift being movable in said aperture in a direction axially of said pedestal and being rotatable so as to cause the second set of grooves in the lift platform to become aligned with the parallel grooves formed in the slide plate, and a plurality of unitary elements slidably mounted in the grooves formed in the guide plate and in the platform so as to form a wide variety of geometric patterns.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
176 words
A two dimensional logical toy comprising a frame structure having a slide passage formed therein, a slide plate slidably mounted in said slide passage and having a plurality of parallel grooves formed in a surface thereof and an aperture extending therethrough, a lift having a platform normally disposed in said aperture and having a first group of parallel grooves formed in a surface thereof and normally in alignment with the grooves formed in said guide plate respectively, said lift being movable so as to cause said platform to move out of said aperture and being rotatable and having a second group of parallel grooves formed in said surface of said platform which are disposed in normal relation to said first group of grooves, so that predetermined rotation of said lift and movement of said platform back into said aperture causes said second group of grooves to become aligned with the grooves formed in said slide plate, and a plurality of unitary elements slidably mounted in said grooves formed in said guide plate and in said platform.
Claim 2
Dependent Claim
176 words
A two dimensional logical toy comprising a frame structure having a slide passage formed therein, a slide plate slidably mounted in said slide passage and having a plurality of parallel grooves formed in a surface thereof and an aperture extending therethrough, a lift having a platform normally disposed in said aperture and having a first group of parallel grooves formed in a surface thereof and normally in alignment with the grooves formed in said guide plate respectively, said lift being movable so as to cause said platform to move out of said aperture and being rotatable and having a second group of parallel grooves formed in said surface of said platform which are disposed in normal relation to said first group of grooves, so that predetermined rotation of said lift and movement of said platform back into said aperture causes said second group of grooves to become aligned with the grooves formed in said slide plate, and a plurality of unitary elements slidably mounted in said grooves formed in said guide plate and in said platform.
Claim 3
Dependent Claim
20 words
A device according to claim 1 wherein said unitary elements comprise a plurality of readily identifiable groups of unitary elements.
Claim 4
Dependent Claim
65 words
A device according to claim 1 wherein a slide limiting passage is formed in said frame structure immediately adjacent to and in communication with said slide passage and wherein a slide limiting block is movable with said slide plate and engageable with the extremities of said slide limiting passage for determining the limits of sliding movement of said slide plate relative to said frame structure.
Claim 5
Dependent Claim
41 words
A device according to claim 3 wherein an aperture is formed in said slide limiting plate and wherein said lift includes a pedestal disposed in said aperture in said slide limiting plate on one end of which said platform is secured.
Claim 6
Dependent Claim
21 words
A device according to claim 4 wherein said pedestal is slidable and rotatable in said aperture in said slide limiting plate.
Claim 7
Dependent Claim
21 words
A device according to claim 5 wherein a flange is formed on the end of said pedestal remote from said platform.
Claim 8
Dependent Claim
32 words
A device according to claim 1 wherein a transverse groove is formed in said frame structure which is disposed in normal relation with said plurality of grooves formed in said slide plate.
Claim 9
Dependent Claim
27 words
A device according to claim 7 wherein said groove in said frame structure and said grooves in said slide plate are disposed in substantially the same plane.
Claim 10
Dependent Claim
30 words
A device according to claim 7 wherein a transverse groove is formed in said slide plate which is in normal relation with said parallel grooves formed in said slide plate.
Claim 11
Dependent Claim
17 words
A device according to claim 1 wherein said unitary elements are of substantially uniform size and configuration.
Claim 12
Dependent Claim
25 words
A device according to claim 1 wherein each of said unitary elements comprises a base portion and a top portion interconnected by an intermediate portion.
Claim 13
Dependent Claim
72 words
A device according to claim 11 wherein said base portion is of greater transverse dimension than said intermediate portion and wherein said grooves formed in said slide plate, in said platform and in said frame structure are configured to accommodate sliding movement of said unitary elements while preventing dislodgment of said unitary elements from said grooves in a direction out of the plane of the surface in which the grooves are formed.
