A building model connector is disclosed comprising a central body, an arm extending outwardly from the central body, the arm including a first arm portion, and a second arm portion, and first and second gripping teeth formed at the distal end of the first arm portion and the second arm portion, respectively, on the inner surface thereof. The first and second gripping teeth are configured to removably connect to a form such as a building panel. Corresponding systems and methods also are disclosed.

A cost effective, structural building set, suitable as a toy, uses 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, 180). 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.

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.

Provided is a toy, game, or puzzle building system. The building system may comprise variously shaped clips that are operatively attachable to cards, paper, or the like. The clips may have a receiving portion adapted to receive the edge of a card or another clip and may connect two, three, four, five, etc. cards or clips in various angles and orientations. For instance, two cards or clips may be connected in a straight line, at a right angle, at an obtuse angle, at an acute angle, etc. Multiple cards may be inserted into each receiving portion of the clips and the cards may be folded, cut, or otherwise manipulated to create a myriad of shapes. Cards may be provided as a part of the building system and may have various shapes, sizes, and images thereon that may be built into a particular item, vehicle, animal, person, building, scene, or landscape. The building system may also allow for freehand building and can incorporate any existing card or paper, such as playing cards, baseball cards, greeting cards, photographs, collector cards, notecards, etc. The various components and versatility between components allow for the creation of limitless configurations, shapes, and images.

A construction kit is disclosed. The kit includes a plurality of connector hubs, links and connectors. A connector may be removably connected to a connector hub via a link. A link may be removably connected to a connector hub. Each link is configured such that a linking distance of the link, which is defined as the distance between a link face of the link and a vertex of the connector hub to which it is connected in use, is or remains substantially constant irrespective of an angular position of the link relative to the connector hub. Each link defines a linking axis which intersects a vertex of the connector hub to which the link is connected, in use. The kit may also include other components, such as couplings permitting connectors to be attached to each other, as well as integrated hub-and-link components and integrated connector-and-link components.

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.

A dog toy comprises a first component having a body that defines a cavity, the body having an opening into the cavity. The dog toy also comprises a second component having a body comprising a first protrusion and a second protrusion. Each of the first protrusion and the second protrusion is selectively insertable into the first component opening in a manner where it remains within the opening to close the opening and is removable from the first component opening when a separation force is applied. The separation force for the first protrusion is different than the separation force for the second protrusion. A treat can be inserted into the first component cavity, the first component cavity can be closed by insertion of the first protrusion or second protrusion into the first component opening, and a dog can gain access to the treat by separating the first component and the second component.

This invention relates to a modular gaming map, where a set of components can be assembled into a variety of configurations to create a three-dimensional map as a supplement for simulated battles and role-playing games, and compatible with industry standard figurines and models.
