Abstract: A construction toy comprises a multiplicity of straws, wherein at least some of the straws are joined together with a first straw extending through a second straw via a pair of transversely aligned holes in the second straw. Further, at least some straws are joined together longitudinally by an end of one straw extending tightly into an enlarged socket end of another straw. The invention includes a punch for punching the transverse holes in a straw, a cutter for cutting the straws to a desired length, and an expander for forming the enlarged socket in an end of a straw.

Abstract: A spatial logic or manipulative puzzle in the form of a 2×2×2 cube is provided comprising a body made of interconnected pieces, groups of which are relatively rotatable about three axes to exchange positions of the pieces, wherein exposed faces of the pieces are sculptured to define an image. Each piece has means for establishing a pivotal connection to other pieces of the puzzle, at least three planar faces for slideable abutment with adjoining faces of other pieces, and at least one exposed face which is sculptured to define part of an image. The internal mechanism is preferably controlled by a castellated spider fixed in relationship to one of the pieces. A mechanism of this type enables the pieces and components to be interengaged and secured together by pushing the last piece home and does not require internal screws or springs or gluing as in some other known cube mechanisms.

Abstract: A book which comprises: first and second rigid covers, a plurality of rigid pages, and binding means attached to an edge of each rigid cover and each rigid page, wherein at least some of said rigid pages are of a different size to others of such rigid pages so that when said book is closed, said plurality of pages is sandwiched between said first and second covers to form a three-dimensional sculpture.

Abstract: A toy construction kit, particularly a three-dimensional puzzle, including a plurality of generally regular polygonal construction elements that can be releasably assembled, through tab-and-slot, hinged interengagement, to form a toy construction. Each of the construction elements is formed from a resiliently flexible sheet of plastics material, for example, polypropylene. A single toy construction may include construction elements in regular polygonal shapes of triangles, squares, and pentagons with all of the sides of the elements having, the same length. The tab-receiving slots of the tab-and-slot engagement may be provided in flanges formed integrally with and projecting from the sides of the construction elements.

Abstract: Apparatus for playing a game, comprising a set of playing pieces having at least three distinct identifiable subsets and a playing surface arranged to receive the pieces and maintain them in a row and column matrix with pieces touching adjacent pieces defining the columns of said matrix and with said matrix being filled with less than the set of said pieces, guide means fixed in relation to said playing surface guiding the pieces for movement along the columns between their ends and permitting pieces to enter and leave each column from its ends so that insertion of a piece at one end of the column causes the pieces to be displaced along the column with a piece being discharged from the other end of the column, and means defining a unique direction in which pieces move along each column.
