A flexible modular construction device comprising tongue portions (26) and flap portions (18) extending from a polygonal body (12). The polygonal body and flap portions have openings (16; 22) which are similar in size and shape, such that the tongue portion can engage said openings simultaneously. Slits (24) between the polygonal body and flap portions allow the tongue of other construction modules to pass through and engage with the openings of overlapping flap and body portions on other modules in an interweaving manner. The margin between body portions, flaps, and tongues is marked with integral hinges (14; 20; 28) which allow the user to assemble stellated forms and other articulated and convertible geometric structures. Accordingly several advantages are to provide an improved construction device, to provide means of increasing the ease of assembling more structurally stable forms, using a more user-friendly and versatile modular construction device.

Disclosed herein is a toy building unit for playing capable of folding from a flat position into a three-dimensional hollow position.

A stackable block, comprising: a wall having an inner surface and an outer surface, the wall comprising a strip of material having a first end and a second end with a plurality of transverse fold lines spaced there between, the wall configured to define a structure having an upper perimeter and a lower perimeter, wherein the structure is formed by the strip being folded about the transverse fold lines and the first and second ends being connected together, and wherein at least a portion of the inner surface is vertically offset from the outer surface such that the upper and lower perimeter have stepped configurations.

Provided is a toy, game, or puzzle building system. The building system may comprise variously shaped clips that are operatively attachable to cards, paper, or the like. The clips may have a receiving portion adapted to receive the edge of a card or another clip and may connect two, three, four, five, etc. cards or clips in various angles and orientations. For instance, two cards or clips may be connected in a straight line, at a right angle, at an obtuse angle, at an acute angle, etc. Multiple cards may be inserted into each receiving portion of the clips and the cards may be folded, cut, or otherwise manipulated to create a myriad of shapes. Cards may be provided as a part of the building system and may have various shapes, sizes, and images thereon that may be built into a particular item, vehicle, animal, person, building, scene, or landscape. The building system may also allow for freehand building and can incorporate any existing card or paper, such as playing cards, baseball cards, greeting cards, photographs, collector cards, notecards, etc. The various components and versatility between components allow for the creation of limitless configurations, shapes, and images.

The presently disclosed technology is directed towards two-dimensional clothing for a doll that has a portal or passage way for a head and neck of a doll to pass through and which further has shoulder straps that rest on at least one shoulder of the doll. In addition, such a device has a fold line at a line of symmetry between a front side and back side of the clothing which is used to fold the clothing or to adjust the clothing based on the size or fashion style of a doll.

A method and system of attaching rivets to secure sheets of paper together. The rivets have a head, a recess, a skirt and a tail. A tool is configured so that the tail fits through a hole in the tool. Before the tail is inserted into the hole in the tool, the tail is inserted through two holes in the paper(s) and then in the hole in the tool. Pressure is placed on the paper by pressing downward on the tool thereby causing the paper(s) to snap into the recess, thereby securing both pieces of paper together.

An invertible interactive toy structure comprising a series of adjacent foldable segments that can be assembled by folding in either of two different directions and joined at its outer edges to form a self-standing toy structure. When folded in one direction, the assemble structure displays its outside features. When folded in the opposite direction, the assembled structure displays its inside features. Figures which correspond to the indicia on the walls of the structure are provided. The figures are removably affixed to corresponding indicia on the walls of the toy structure. In a particular embodiment, the structure is a barn and the inside features represent various items or scenes associated with farming.
