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 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.

A method and system of attaching rivets to secure sheets of paper together. The rivets have a head, a recess, a skirt and a tail. A tool is configured so that the tail fits through a hole in the tool. Before the tail is inserted into the hole in the tool, the tail is inserted through two holes in the paper(s) and then in the hole in the tool. Pressure is placed on the paper by pressing downward on the tool thereby causing the paper(s) to snap into the recess, thereby securing both pieces of paper together.

Building sets including one or more blocks or planks and one or more connector clips configured to engage a thickness of the planks. Various types of planks, as well as various types of connecting clips may be provided, so as to provide open-ended building characteristics to users. Some connector clips may include a mating protrusion allowing the connector clip to be coupled to a hole or receptacle of another connector clip, or hub for connector clips, or into a hole of a plank. Such clips may be pivotable relative to the structure coupled to as a result of the mating protrusion connection. The building sets may provide proportional dimension characteristics between the planks and various connector clips, hubs, etc. One or more button connector clips may be provided with one or more panels, allowing panels to be integrated into the structural framework created with the connector clips and planks.

Provided is a toy building system. The toy building system may comprise one or more of interconnecting tiles, flat tiles, arcs, line reactors, clips, tracks, rotatable tracks, split tracks, launchers and other pieces that are adaptable to connect in a multitude of configurations and may be set up in sequence to create a chain reaction of falling as in dominos. Various types of tiles or “falling units” may be utilized, including line reactors, arcs, or tiles having a multitude of different mating components and orientations including an interconnecting orientation and a flat orientation. The domino tile may further connect to other pieces of the toy building system including an arc or a rapid track builders including a track and a clip. The tiles, independently set up, as a part of the arc, or as a part of the rapid track and/or line reactors may be positioned so as to create a domino effect when a force is applied thereto, such as a force applied by a launcher. The various components and interconnectability between components allow for limitless configurations as building blocks and as a domino show.

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 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 marble run track connection arrangement for use with a plurality of physically interconnectable marble run elements includes a marble track section, a tube, and a connector. The marble track section has first and second connecting posts coupled to or forming a portion of a marble travel path of the marble track section. The tube includes a connecting portion configured to directly physically connect to another tube. The connecting portion passes a marble from or to the other tube. The tube also has a side opening configured to receive a marble therethrough into or out of an interior of the first tube. The tube also includes a track connector extending outward from the tube. The connector is configured to receive the first and second connecting posts and to couple to the track connector such that a path is defined between the marble travel path and the interior of the tube.

Connection systems for toy construction pieces, toy construction pieces, and toy construction kits. A connection system includes a male connection element and a female connection element. The male connection element includes a peg unit with a connector peg. The female connection element includes at least a portion of a connector core that defines a receiver cavity configured to receive at least a portion of the connector peg and at least a portion of a core shell. A toy construction kit for assembling a constructed assembly includes a plurality of toy construction pieces that collectively embody the connection system. A first construction piece includes the male connection element and a second construction piece includes the female connection element. The connection system is configured to selectively and repeatedly couple the first construction piece and the second construction piece to one another.

The invention relates to a connecting system 1, comprising at least one hole carrier 2 with a row of side openings 4 made therein in a longitudinal direction, the openings being aligned in a first orientation and in a second orientation orthogonal thereto and being made transverse to the longitudinal direction, wherein the side openings 4 of the first and the second orientation are shifted by one half the distance between two side openings 4. According to the invention, the distance between two side openings 4 is smaller than the clear width of the side openings 4, the side opening 4 of the second orientation being made within this distance and the side openings 4 of the first and the second orientation partially penetrating one another. The invention further relates to a method for building an assembly from a connecting system 1 and to a use of a connecting system 1 having the associated securing and connection elements and the installation sequence.
