A toy building brick system includes a base brick having a cubic shape such that the base brick comprises six outer walls. The base brick has an open interior and each of the outer walls comprises a female receiver such that six female receivers are formed in the base brick. In this manner, the base brick defines an all-female brick. A plurality of inserts is provided and each of the inserts is removably engaged with one of the female receivers such that an outer surface of each of the inserts faces outwardly of the open interior.

The present disclosure relates to toy construction kits and assemblies and, more particularly, to connectors that are mechanically attached to and extend from the corners of geometric frame-like modules. The connectors are also adapted to interface with and magnetically connect to linear magnetic modules, whereby a user can create multiple construction platforms upon which a number of diverse and interesting structures can be assembled.

A construction system includes at least two building elements provided with one or more cylindrical holes and one or more connection pins having a first end, a second end and a longitudinal axis. The connection pins are configured to be detachably inserted into the holes and hereby connect two adjacent building elements. The connection pins are provided with a first notch extending along the longitudinal axis and a second notch extending along the longitudinal axis, wherein the first notch extends from the first end to a position between the first end and the second end, wherein the second notch extends from the second end to a position between the first end and the second end. The width of the connection pins is larger than the width of the cylindrical holes.

The invention relates to a modular construction system comprising at least one object and a coupling element releasably connectable to the object, wherein: the object comprises at least one surface with at least one opening, which opening comprises a number of inward extending lips arranged distributed over the periphery of the opening; the coupling element comprises a body with an axial axis arrangeable in the opening, which body is provided along its outer periphery with at least one outward extending locking cam; wherein the coupling element is arrangeable in at least one arranging orientation in the opening of the object, and is rotatable in the opening relative to the object to at least one locking orientation, in which locking orientation the coupling element is locked in an axial direction and a rotational direction. The invention also relates to a coupling element, object and tool intended and configured to form part of such a modular construction system. External elements such as a skin plate, a fabric, a cord or the like can be attached to a structure according to the invention by means of an attaching element with a shank and a widened head, which shank can be inserted releasably into a continuous opening of a coupling element.

The invention relates to a coupling element comprising a body with an axial axis arrangeable in an opening of an object, which body is provided along its outer periphery with at least one outward extending locking cam, wherein the body is provided with at least one resiliently movable tongue extending therefrom, to which tongue the locking cam is connected, wherein the at least one tongue is movable inward by a force being exerted thereon.

The present invention relates to a unit block having a coupling portion and an insertion portion provided in special structure and shape such that, instead of providing an assembly-type toy that makes a user build an assembly-type completed product according to the manual, the user is enabled to implement various articles by exercising creativity without feeling bored. The present invention provides a unit block, which has integrally provided coupling and insertion portions, and provides, as a means for using the same when a desired object is to be implemented.

A constructional toy comprising a plurality of elements which can be assembled together to form a variety of three dimensional structures. The elements include a triangular prism shaped brick element comprising a plurality of walls. The walls define a male mating side having a male engagement feature which extends from the brick. The walls also define a female mating side which defines a cavity configured for receiving an engagement feature of the same configuration as provided on the male mating side.

A grid for a snap-together electronic toy set is disclosed. The grid includes: a planar, non-conductive member; a plurality of spaced-apart, non-conductive snap-fittings; at least one first electrically conductive snap-fitting; and at least one second electrically conductive snap-fitting. The planar, non-conductive member includes first and second opposed surfaces. The plurality of spaced-apart, non-conductive snap-fittings are connected to the first opposed surface. The at least one first electrically conductive snap-fitting is connected to the first opposed surface in spaced-apart relation to the plurality of spaced-apart, non-conductive snap-fittings. The at least one second electrically conductive snap-fitting is connected to the second opposed surface. The at least one second electrically conductive snap-fitting is electrically conductively connected to the at least one first electrically conductive snap-fitting.

ABSTRACT An interlocking frame for selective engagement with a plurality of adjoining interlocking frames is presented herein. The frame includes a frame body that defines an interior portion at least partially enclosed by a plurality of interior walls, a front face, a rear face, and a plurality of peripheral walls. The interlocking frame also includes a plurality of locking tabs each selectively and independently rotationally disposable between a retracted position and an extended position relative to the frame body. Each of the locking tabs has an arm that extends beyond the frame body when the locking tab is disposed in the extended position in order to engage with a corresponding locking slot of an adjacent frame.

A system of interlocking blocks and rods or tubes for rapid assembly of component infrastructures, where one or more of those components have electronics, power or other instrumentalities built into the component during manufacture, such as by 3-D printing, and the components thereof and methods therefor. The rods or tubes, blocks (for interlocking the rods/tubes) and through-holes allow not only structural stability but interconnectivity of electricity, power or other functionalities. The methodology of the present invention provides a paradigm for modeling more costly and complicated systems. Also, product packaging for products made pursuant to the present invention is scaled so as to be usable in the application of the parts.
