The present invention relates to a straightly assembled block comprising engaging assembly means configured in male and female types, first ends of which can be coupled to each other, such that male and female piece blocks can be assembled by connecting the same to each other straightly, and the engaging assembly means are improved such that wear is prevented in spite of repeated separation/coupling, thereby maintaining continuous assembly power. To this end, the male and female piece blocks have engaging assembly means, first ends of which protrude in arc shapes, and the second ends of which are coupled to each other. Alternatively, connecting blocks have engaging assembly means formed on both ends thereof in different types. The engaging assembly means formed on the piece blocks or on the connecting blocks comprise a recessed portion and a protruding portion. Each of the recessed portion and the protruding portion has a guide means and a coupling means provided on both coupling surfaces thereof, respectively, the coupling means being guided along the guide means so as to engage, such that the same are connected on the same straight line. An incision hole for an elastic action is formed from a corner of the recessed portion toward the interior, on which a rotating shaft is formed, such that, when the protruding portion is guided and coupled, the incision hole is elastically operated so as to widen the recessed portion in the leftward/rightward outward direction, thereby preventing wear of the engaging coupling means.

A device for cutting and bending a hollow elongate tube. A measuring subassembly is adapted for measuring a desired size of the tube. A cutting subassembly is adapted for cutting the tube to the desired size. A bending subassembly is adapted for bending the cut tube to a desired angular orientation. The bending subassembly includes a base controlling a radius of a bend to be formed in the cut hollow elongate tube, and a user grippable handle. The user grippable handle is configured to enable a user to rotate the cut hollow elongate tube, relative to the round base, to form the bend in the cut hollow elongate tube.

The present invention relates to construction assemblies or modules. There are attachment members that are connected by pressing an elastic protrusion head through an aperture and threading the protrusion head from one side of the aperture to the other. As the area of the aperture is smaller than area of front projection plane of the protrusion head, threading the protrusion head into the aperture requires the deformation of the protrusion head. After traversing the aperture, the protrusion head returns to its non-deformated shape, and the protrusion neck is settled within the aperture.

The invention is a cost effective, structural building set, suitable as a toy, using post connectors (10) comprised of a post (12) with attached disks (14), or similar devices that insert into cutouts (31) in geometric shaped component parts (30, 80). More than one component part can be connected to the same post connector, and such component parts can rotate relative to the post axis. The connector design allows construction of stable structures of many sizes, shapes, and types, and readily facilitates hinging between different sections of such assembled structures. Many variations of the invention are possible, including connection with other types of construction elements (530, 570, 580, 584, 602, 640), structural element figurines (900), spinors, (512), various shape post connectors (612, 618, 620, 611) and faceplates (632), blocks (550), faceplates (576), lenses (590), catapult/slingshot (680), periscope mirrors (660), tubes (672), wheels (925), spherical elements (915), figurines (900), animal parts (944, 947, 950), and plane parts (954, 955) and more.

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.

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 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.
