The invention describes a new constructor module with the additive aspects of sound and dynamic construction. A base block is provided with varying mating elements for adjustably connecting structural blocks and plates together with sounding elements. A plurality of base blocks may be constructed based on desired output in various shapes and structures. The base blocks are coupled together with connecting elements and fixing pins, which also assist in coupling the sounding elements. Additional plates are also utilized for creating dynamic sounds and structures, including D-shaped plates and U-shaped plates. Constructor set modules may utilize all such elements in a plurality of structures, or at minimum, only base blocks, connecting elements, a sounding element, and fixing pins.

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.

A system comprising a plurality of blocks is disclosed. Each block has a cuboid body and a connecting member extending away from each corner of the cuboid body, such that for each connecting member there is a first opposed connecting member, a second opposed connecting member and a third opposed connecting member, and a connector engagement arrangement is defined between a connecting member and each of the first, second and third opposed connecting members. The system also comprises a plurality of connectors, each connector having a body with a first connection end for engagement with a connector engagement arrangement of a first block and a second connection end for engagement with a connection engagement arrangement of a second block so as to connect the first block to the second block.

A construction teaching set for education. A polyhedral block body has first and second divided members and provided by engaging and assembling of the first and second divided members. Each of the first and second divided members has a rectangular plane, a plurality of rectangular inclined surfaces adjoining sides of the rectangular plane, triangular connectors formed between the adjacent rectangular inclined surfaces, and a plurality of vertical skirts extending from the plurality of rectangular inclined surfaces and the triangular connectors. A connection bar has a protruding fastener at one end or both ends to be selectively connected to one among a first fastening hole passing through the rectangular plane, second fastening holes passing through the plurality of rectangular inclined surfaces, and third fastening holes formed in a pair of the vertical skirts adjoining each other. A coupling unit generates coupling force for the first and second divided members.

A bracket for modular luminaire includes a polyhedral module and a connector connected to the polyhedral module. The polyhedral module is a polyhedron provided with a cavity therein, and each surface of the polyhedron is provided with a stepped through-hole connected to the cavity, thereby forming a first annular protrusion at a junction of the stepped through-hole and the cavity. The connector includes a connector body having a cylindrical shape. On an outer periphery of the connector body, a second annular protrusion, a third annular protrusion, a fourth annular protrusion, and a fifth annular protrusion protrude outwards in a radial direction and are spaced apart from each other, and formed successively from a left end portion to a right end portion of the connector body. A left end of the connector is inserted into the stepped through-hole of the polyhedral module.

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.

An insert-and-twist building block structure includes a connection bar and a connection terminal unit. The connection bar has an end from which a combination projection section extends and has a conic shape. The combination projection section has an external circumferential surface formed with a bead ring including multiple raised beads intermittently arranged in a ring configuration. The connection terminal unit includes a connection terminal having an end inward recessed to form a combination cavity in a conic shape. The combination cavity has an internal circumferential surface formed with a groove ring including multiple recessed grooves intermittently arranged in a ring configuration. The recessed grooves each a middle portion forming a deep trough section and two ends each forming a shallow trough section, and a depth is decreased from the deep trough section toward the shallow trough sections.
