An object is to provide, in place of a cube toy such as Yoshimoto Cube, a wide variety of playing patterns, playing patterns which cannot be predicted in terms of change in forms, a polyhedral toy which can be enjoyed in terms of change in form even when only one polyhedral toy is used, and a polyhedral toy having extensibility for achieving a wide variety of contents of play through combination of two or more polyhedral toys. Therefore, when a polyhedral piece (U1) forming the toy is formed with three quadrangular pyramids (G1 to G3) having, among six triangular faces (T1 to T6) of a cube (R), three faces (R1 to R3) as bottom faces, the polyhedral piece (U1) includes a triangle surface (10) formed of six triangular faces (T1 to T6) other than respective side faces of the quadrangular pyramids (G1 to G3) placed on one another. When polyhedral pieces (U1 to U8) each having the configuration described above form a toy (1) unfolded into a cuboid shape of two rows and four columns as illustrated in FIG. 1, in plan view on a top face of the toy (1), in each of the first row and the second row, the triangle surface (10), the third face (R3), the third face (R3), and the triangle surface (10) are arranged in the stated order.

The present invention relates to three-dimensional puzzles with segments capable of changing position in relation to one another, said segments having guides for allowing the movement of movable elements. According to the invention, the movable elements are configured in the form of permanent magnets, wherein the movement of each magnet is limited by its own guide, and each magnet is capable of being positioned in at least one of two end positions, wherein the guides in the movable segments are arranged to allow different magnets to interact with one another and to change position relative to movable elements. Movement of the magnets is provided by both the attraction and the repulsion of different magnets. The technical problem addressed is that of increasing the existing assortment of puzzles having movable segments.

A panel and a system for use in building a lightweight structure are provided. The panel, made of a film or a sheet capable of being curved or bent with fingers, includes a body in a geometric shape circumscribed by straight or curved edges, and at least one joint formation along the edge for panel connection. The joint formation has tabs separated by at least one gap. Each tab expands bilaterally and proximally from the body at its base, and each gap is positioned along the edge so as to accept the base of the tab. The joint formations along the edges of varied curvatures are alignedly, hingedly, and detachably interlocked with each other by twisting the panels with fingers to individually hook the tab at the gap. The panels are assembled into geometric structures having flat or curved faces.

Systems and methods which provide for interactive haptic proxies for hand-graspable virtual reality (VR) objects using reconfigurable artifacts and facilitated through use of a haptic reconfigurable artifact toolkit are described. Embodiments provide a haptic reconfigurable artifact toolkit including a set of reconfigurable artifacts for use in forming reconfigurable artifact-based haptic proxies, a set of haptic hardware components for use with respect to reconfigurable artifact-based haptic proxies, and a haptic reconfigurable artifact software platform configured to facilitate generation of reconfigurable artifact-based haptic proxies using items of the set of reconfigurable artifacts and the set of haptic hardware components. Reconfigurable artifacts may be shaped to form reconfigurable artifact-based haptic proxies covering a wide range of hand-grasp postures.

Puzzle kits include a first puzzle and a second puzzle, each of which is formed of a plurality of polyhedral modules, or polyhedrons, connected by hinges in a continuous loop. Each polyhedron includes four faces, six edges, and at least one magnet disposed adjacent to at least one face. Magnetically stabilized assemblies of the first puzzle and the second puzzle form at least a convex polyhedrons, such as a cube.

A magnetic sticker with folding puzzle panel, comprising a left front L-shaped panel assembly, a right front L-shaped panel assembly, a left rear L-shaped panel assembly, a right rear L-shaped panel assembly, a left upper panel, a right upper panel, a front lower panel, a rear lower panel, a first upper sticker, a second upper sticker, a plurality of inner stickers, a first lower sticker, a second lower sticker, and at least two magnets, so that the magnetic sticker with folding puzzle panel not only can be attached on fridges or other metallic surfaces, but also can be folded into different shapes to show a variety of images, colors, or photos.

The present disclosure relates to a toy. In some embodiments, the toy includes first cubic blocks, second cubic blocks, connectors, and pivoting shafts. For example, the first cubic block includes a first recessed space recessed from a first edge to a first center of the first cubic block, and a second recessed space recessed from a second edge to the first center. The second edge is perpendicular to and does not intercept the first edge. The second cubic block includes a third recessed space recessed from a third edge, and a fourth recessed space recessed from a fourth edge. Each of the connectors connects one of the first cubic blocks and one of the second cubic blocks. Each of the pivoting shafts connects a respective connector to one of the first and second cubic blocks that is configured to rotate around the respective pivoting shaft.

A transformational toy comprises at least six polyhedron bodies, at least one connection strip for connecting the polyhedron bodies in a chain, wherein the connection strip provides hinges between every pair of adjacent polyhedron bodies of the chain, wherein the hinges facilitate movement of the polyhedron bodies between at least two different geometric transformations of a combined body of all polyhedron bodies, wherein at least one of the connection strips is connecting at least three adjacent polyhedron bodies.

Pentahedral module puzzles include a plurality of pentahedral modules connected by hinges in a continuous loop. Each pentahedral module comprises at least one magnet. The pentahedral modules include mirror image pentahedral modules connected by the hinges in an alternating sequence.
