Provided herein is a set of card-like structure and connector toys for building; the set comprising one or more card-like structures and one or more end cap connectors, wherein the one or more end cap connectors comprise one or more slots for inserting the card-like structures. Also provided herein is a connector toy or a kit of connector toys; comprising one or more slots for inserting card-like structures for building.

A vehicle configured to move through a network of interconnected tubes includes a body, a motor, a motorized wheel, a biasing assembly, and a first element. The motorized wheel directly engages an inner surface of the tubes. The biasing assembly causes the motorized wheel to maintain continuous contact with the inner surface of the tubes during operation. A waist of the vehicle is constrained by an inner diameter (D) of the curved tube, a radius of curvature (R) of the curved tube, and a length (L) of the wheelbase of the vehicle. The waist of the body is sized such that the vehicle can freely move within any of the tubes without getting stuck therein.

The invention relates to a modular structural system obtained from the combination, in sliding engagement form, of generically elongated elements A, B, C, D having sections whose perimeter is provided with protrusions and recesses which, in the spatial development of the elements A, B, C, D, form sliding channels or tracks for mutual sliding of the elements which form the structural system. The structural system may also be provided with node elements C shaped so as to have two parallel opposite surfaces, one of which is provided with sliding channels or tracks for mutual male/female engagement in corresponding sliding channels or tracks and the other surface of which is provided with a permanent or releasable connection with other elements A, B, C, D at a connection angle of 0<a<180 with respect to said opposite surfaces. The structural system may also be provided with nodes A, B, C instead of the node elements C.

The present invention relates to a prefabricated toy frame including a body; and a clamp formed on at least one portion of the body and interconnected with an opposing body, wherein the prefabricated toy frame which can securely fix blocks without a separate coupling component and is formed so that a user easily makes a desired shape by being interconnected in various shapes.

A play structure is formed from flexible struts supporting a fabric. The struts are inserted through pockets along the edges of the fabric. The struts are joined together by connectors at apexes of the structure. The struts form an upper frame and a lower frame. The upper and lower frames are connected by battens. The struts and battens hold the fabric in a selected shape, such as a sailboat. The battens are formed from flat, flexible members that are bent about their longitudinal axis to form a C-shaped cross section. Ends of the battens are inserted into curved batten receivers on the connectors. When a downward force is applied, the upper frame is pressed toward the lower frame. The battens bend and flatten to resiliently allow the structure to collapse. When the force is relieved, the battens resiliently resume their curved shape, restoring the structure to its original configuration.

A wall component for receiving associated alignment clips is illustrated and described. The wall component comprises a molding strip, an array of mounting studs, and a molding frame that is inserted between a pair of wall panels. More specifically, the mounting studs are affixed to an inner surface of the molding strip and inserted through the wall panel where they are secured to the molding frame. A gap is formed between the inner surface of the molding strip and an outer surface of the wall panel for receiving associated alignment clips. The alignment clips are releasably secured to the wall component by interlocking with the mounting studs in the clip receiving gap and/or wedging the gap. The alignment clips may be affixed along an abutment edge of the wall segment or to associated model pieces. Model pieces may also be laterally slidable with respect to their associated alignment clips.

A modular play structure is disclosed. The play structure has a plurality of wall units that can interchangeably couple to form a modular playhouse. The wall units are coupled together by a mating structure. Some embodiments have a separate connector that couples wall units together at the edges of the wall units. Some embodiments have accessories coupled to the wall units at accessory openings. Some embodiments have decorative faades configured to removably attach to the plurality of wall units.

An environmentally friendly knockdown building block set includes a cardboard shipping box; a plurality of main cardboard blanks each configured to form a base block including four connecting slots therein as wide as the base block thickness; a plurality of coupling cardboard blanks each configured to form an H-block including two connecting slots therein with each slot located between two legs of the H-block and as wide as the H-block thickness; wherein the connecting slots of each base black and each H-block allow for receipt and interconnection of the base block or H-block with an associated base block or H-block forming a notched connection for the base blocks and H-blocks; wherein at least the main blocks include an inking pattern using plant based environmentally friendly inks; and wherein the shipping box is an integral component configured to be integrated into structures formed by the set.

A Toy assembly includes a flexible joint element and a construction member. The flexible joint element comprises two spherical components and a flexible string. The two spherical components are coupled to the flexible string at the two ends of the flexible string. The construction member comprises two slots and two holes which can receive the flexible joint element. Multiple construction members can be assembled, utilizing flexible joint elements, to construct toys or other structures with members having six (6) degrees of freedom.

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.
