Abstract: A toy connector in accordance with the present invention joins first and second structural elements which are aligned adjacent one another and engaged to form a flush, secure connection having a female connector assembly joined to the first structural element having at least two recess elements and at least one female snap element disposed between the recess elements, and a male connector assembly joined to the second structural element having at least one tongue adapted to engage each of the recess elements, and at least one male snap element adapted to engage the female snap element.

Abstract: A playhouse constructed of interlocking logs has a water-tight sloped roof formed by overlapping roof sheets. The sheets are secured to the playhouse by means of roof peak pieces notched at their bottom to interlock with respective notches in a tie beam log. The roof peak pieces have sloped surfaces, each with a bore defined therein for receiving a roof peg extending through one of two holes defined through the roof sheet in spaced relation along an upper edge of the roof sheet. Adjacent roof sheets in the roof structure overlap such that one peg may be inserted through aligned holes in each sheet and into a common roof peak piece bore.

Abstract: Children's building blocks that can be attached to each other in numerous combinations by integrally molded connectors located on the faces of the blocks. Some of the faces have apertures and these faces may be joined together to create tunnels between the interiors of two adjacent blocks. Doors are also provided to selectively cover the apertures. Faces having apertures may be connected to faces without apertures for the child to distinguish between an open connection and a closed connection.

Abstract: A model building kit deploying interchangeable wall panels in order to create a variety of building designs. The model building kit includes wall panels made up of interchangeable sub-units which further allows the builder to conform each individual panel to his needs. The wall panels interconnect with one another and are vertically supported by columns. The columns support a roof panel which may be also used in the interior of the building as floors. The style of architecture of the model kit is that of an industrial building such as a factory or warehouse.

Abstract: A changeable book structure in which several panels are joined side-by-side by an elastic hinge to form a book. The elastic hinge may be separated from the panels. Each of the panels has color-coded slots, and certain of the panels also have color-coded tabs receivable in the slots so that the panels may be connected together to form a self-supporting structure, such as a playhouse.

Abstract: A playset including various building facades representing a food store, pet shop, florist, post office, bank and the like have both exterior and interior details with various movable play features. Additional town structures such as mailboxes, benches, lampposts, fences and the like are used between the building facades to connect the facades with each other. Also included with the playset is a line of small, soft body dolls and animal figures representing various family members, town officials and pets.

Abstract: The invention discloses a house or other structure defining an enclosure whose walls are constituted as multiple puzzle pieces. The disclosure extends to any sculpture-like three-dimensional puzzle where the walls defining the sculpture or structure are composed of self-standable puzzle-pieces, and the sculpture or structure is itself self-standing.

Abstract: A carrying case which may be used as a toy building or toy playground. The carrying case has two foldable sides rotatably and removably hinged to its base by breakaway hinges featuring ball and socket portions. The other two sides of the carrying case remain in a vertical position attached to the base. A roof portion is connected to one of the foldable sides by breakaway hinges. The foldable sides and roof portion may be rotated to unfold the carrying case so that it may be used as toy playground. The roof portion has a built-in slide and swing. It may be removed from the carrying case and used as a separate toy. The carrying case may be folded to simulate a toy building or schoolhouse with a roof portion latched to the top of the case.

Abstract: The toy building block kit includes a variety of buildingblock pieces with a first building block piece (e.g., piece 10, 100, 110, etc.) having on at least one side thereof, a longitudinal slot (20, 102, 112, etc.) and a transverse slot (30, 104, 114, etc.), and a second building block piece (e.g., piece 12, 140, 150, etc.) having on at least one side thereof a rib (60, 130, 142, 152, etc.) extending therefrom sized, configured and dimensioned to be received in one of the slots (20, 102, 112 etc. or 30, 104, 114, etc.) in said first piece.The pieces can be elongate, rectangular or triangular and each piece has crossing slots (e.g., slots 20, 30) therein forming a waffle or matrix pattern on the various sides thereof.Also each piece, (e.g., piece 10) may have one or more ribs (e.g., ribs 60) extending from a side thereof for interconnecting with another piece (e.g., piece 12).Furthermore, a variety of specialty pieces, e.g.

Abstract: A playhouse, easily assembled by a child of tender years requiring a minimum of parts and no fastening elements, and having a sufficient structural rigidity that it can be picked up and moved without collapsing. The playhouse comprises a plurality of flat structural members, two of which, when assembled, are vertical members adapted to coact and form a self-standing cross member. A third member having passageways therein adapted to register with the first and second members rests on horizontal intersecting surfaces of the vertical members assembled to form the cross member and adds rigidity to the assembly. The third member also has slots in the periphery which register with the vertical members forming the cross member. At least one of the vertical members has one portion spaced from another portion by a horizontal supporting surface. Both spaced portions have a shoulder at one end thereof which projects through slots in a roof panel.

Abstract: A child's playset comprised of a number of rooms offering different stage settings which may be changed. Each room includes a pair of walls at an angle with respect to each other and a floor having two different heights. The playset is preferably formed by attaching four rooms together at hinges whereby the rooms may be moved with respect to each other to form different shaped playsets. In addition, the rooms may be brought together to form a square wherein a handle extending upwardly from the walls of each room come together to form a central carrying handle for transportation of the playset.
