A system and method of assembling building blocks involves a posable metal linkage comprising a plurality of ends and a Lego-like brick having means for coupling at least one of the plurality of ends of the posable linkage within a cavity located therein.

A three-dimensional logic puzzle is provided. The puzzle includes a plurality of identically shaped puzzle components of an irregular form. Each puzzle component is configured to engage with another identically shaped puzzle component via projections and recesses formed on the sides of the puzzle components. The plurality of puzzle components are interengagably assembled into the form of a predetermined three-dimensional geometric shape.

A modular construction system, including, first and second walls, each having first and second broad surfaces. Each wall includes throughgoing connector-receiving bores. The modular construction system further includes a connector including a longitudinal body portion arranged along a longitudinal axis and having a first width. A head portion of the longitudinal body portion includes a base surface having a second width in a direction transverse to the longitudinal axis. A pair of protrusions extend outwardly from the longitudinal body portion and are disposed between the base surface and a tail end of the longitudinal body portion. The protrusions include an engagement surface facing toward the base surface and having a third width, the third width being greater than the first width.

The present invention provides a connecting structure for plate members, including a projection projected from one of the plate members in a first direction, and a groove provided on the other of the plate members to have inner faces facing each other in a second direction intersecting the first direction and configured to fittingly receive the projection. The projection includes a main body, a resilient portion provided on one side of the main body in the second direction and resiliently inwardly deformable in the second direction, and an engagement portion outwardly expanded in the second direction from the resilient portion and configured to be plastically deformed along and engage with one of the inner faces of the groove when the groove fittingly receives the projection.

A modular block toy and kit that includes a male cubic unit piece having a plurality of faces with a male node extending from each respective face of the plurality of faces, and a female piece having a plurality of faces and corners formed by three intersecting faces, the female piece having a female component formed on a respective face of each of the plurality of faces that is sized and shaped to receive a respective male node enabling connection using any side of the female piece and any side of the male piece, and in which all sides of the female pieces and the male cubic unit pieces with a snapping and interlock design are identical, enabling the pieces to be snapped together using any side of the female or male piece to achieve build out indefinitely in any direction.

A toy construction set comprising a number of toy building blocks forming a construction having multiple coupling sockets, the toy building set further comprises a number of coupling pins and a flexible sheet having at least one hole. Each of the coupling pins extends in a longitudinal direction between a first end shaped for releasable attachment of the pin to one of the coupling sockets, and a second end extending away from the coupling socket in the attached position of the pin in the socket. The second end of the pin comprises a head arranged distally on a neck having a cross section allowing it to pass freely through the hole, and wherein the size and shape of the hole and of the head are adapted to make it impossible to pass the head through the hole without tearing or providing a plastic deformation on the flexible sheet.

A caster, a construction block set comprising the caster and a method of producing the caster. The caster comprises a housing and a wheeled member rotatably attached to the housing, wherein the housing includes an integrated connecting structure arranged to facilitate a separable connection between the housing and a modular assembly, thereby providing a wheeled function to the modular assembly when the caster is installed.

A game has a plurality of game pieces that are configured to be stacked upon one another in a loosely interconnected fashion that permits the stack of game pieces to tumble once the stack becomes unbalanced or unstable.

The present disclosure provides a modeling apparatus having a plurality of modeling devices, each having a generally tetrahedron shape having four faces with an interface element attached to each face. Each interface element cane b removably and rotatably coupled to an interface element of an adjacent modeling device. A combination of modeling devices are selectively couplable to form a variety of structures such as molecular, architectural, artistic, dynamic, and/or any other suitable model. The interface elements can include magnets with distinct or identical polarities, and with selective strengths to emulate the target structure or assembly attributes. They can also be iron or a neutral material such as aluminum. The vertices of the modeling apparatus include a curvilinear boundary tracing a spherical periphery of a sphere having a radius extending from a center point of the tetrahedral shape to a midpoint of an edge thereof.
