A construction system uses a comb connector element in combination with flat or generally planar polygonal shapes of various types. The comb connector elements connect to the edges of the planar polygonal shapes. Each comb connector has at least one pair of connector members. Each connector member has a proximal end connected to the polygonal member, and a distal end. Each connector member having a face portion that includes a recess extending from a central region of the face portion. The recess extends to the distal end of the face member.

A coupling for assembling at least two beverage cans together, comprising at least a pair of collar portions, each to slidably receive a corresponding end region of one of the beverage cans, the collar portions being configured to engage the beverage cans for associated games and/or other amusement activities.

The invention is a construction toy consisting of standard connector elements, e.g., rings, and strut elements, e.g., that may be joined in various angular configurations and with various types of articulation such as fixed, sliding, swinging, spinning, etc. Rings may be provided that have pairs of perimeter orifices that are offset by different amounts wherein the different offsets provide different functionality to ring and strut assembles. Other elements may be included such as pipes, slips, caps, base components and collar components. The elements may be combined to create various forms including a figure with human traits comprised of interconnecting strips and rings of various dimensions, a decoration, a vehicle, a bird, or many other forms in accordance with a user's imagination.

A 3D fort building kit is a device that can create a variety of structures and shapes. In other words, the device has improved materials and designs with better qualities, that enables kids to build complex 3D structures. To accomplish this, the device includes panels, connectors and utility features that help kids to construct and assemble a structure of their choice in many designs. Further, structures may be constructed in many creative designs by allowing the panels to be connected vertically, horizontally, and at any angle. Furthermore, the constructed structures can be disassembled and constructed again to build other designs safely by kids. Additionally, the device is simple, durable, and light weight enough for young kids to build stable and versatile structures of their choice.

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.

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 a kit used for educational and fun purposes that provides components for creating and visualizing complex geometrical shapes. The kit includes small spheres and pegs that can be assembled into multiple geometric shapes, such as polyhedrons. The shapes are created from separate spheres used as vertices that are connected using pegs. Inner spheres including two holes are placed inside the pegs wherein the holes are used for rotating the shapes both horizontally and vertically. A stand includes horizontal spinning rods and vertical rods that are used for rotating the shapes to enable students to visualize and understand the shapes from all angles. The shapes can be assembled and disassembled as per the preferences of a student. The outer spheres, pegs and inner spheres are manipulable parts that provide hours of fun and learning and help students to learn different aspects of geometry.

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 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 door hinge assembly includes: a door frame defining a frame opening and a jamb at one side of the frame opening, the jamb including two frame corners protruding into the frame opening and a jamb brace connecting the two frame corners across the frame opening, the jamb brace defining two spaced-apart hinge holes therethrough; a door movable to selectively provide access through the frame opening, and an elastic cord connecting the door to the door frame, the cord extending sequentially through a first of the two hinge passages, through a first of two passage openings at the jamb edge, through a first of the two hinge holes, across the jamb brace, through a second of the two hinge holes, through a second of the two passage openings at the jamb edge, and through the second of the two hinge passages.
