The present disclosure relates to a toy. In some embodiments, the toy includes first cubic blocks, second cubic blocks, connectors, and pivoting shafts. For example, the first cubic block includes a first recessed space recessed from a first edge to a first center of the first cubic block, and a second recessed space recessed from a second edge to the first center. The second edge is perpendicular to and does not intercept the first edge. The second cubic block includes a third recessed space recessed from a third edge, and a fourth recessed space recessed from a fourth edge. Each of the connectors connects one of the first cubic blocks and one of the second cubic blocks. Each of the pivoting shafts connects a respective connector to one of the first and second cubic blocks that is configured to rotate around the respective pivoting shaft.

The invention relates to a modular education and toy block having at least one piece 10 having a body (11), a jointer (20) working with comb fitting principle (finger joint), having recesses and/or protrusions that each of them is in triangular on at least one surface of the joinder (20) which is appropriate to form new pieces (10) by combining the piece (10) with another piece (10).

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 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.

A building block of six female sides wherein each side of the block is adapted to accept a male side of a second different block. The first block is made up of a cross form comprised of tubular projections, a skeleton block form, and connection components connecting the cross form to the skeleton block form. The second different blocks are made up of at least four generally cylindrical projections extending normally outward from the base plate of the block that may be inserted into any of the six sides of the first block and interconnect by frictional engagement. These blocks can be interconnected and assembled into a block structure that has both a finished outward appearance in which each outermost side of every block is customizable and provides internal passageways for adding structural elements, wiring, lighting or anything else needed to run through the blocks and block structure.

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.

The kit of construction elements includes a plurality of construction elements and a plurality of rod-like binding elements for connecting said construction elements, wherein the construction elements are in the form of square-based rectangles, and wherein on at least one of the faces of each construction element perpendicular to the base thereof at least one groove is formed in parallel to its base, and along at least one edge of each construction element a groove is formed for receiving a binding element, wherein each binding element is formed to fit into a groove along at least a part of its entire length and further provided with securing members formed to engage with complementary securing members of said groove by form-fitting or force-fitting, and wherein the grooves of the construction elements and the binding elements are sized so that during use the construction elements are substantially in contact along their connecting surfaces.

A toy construction set includes first and second construction elements, a pin, and a fastener including a body and a head. Each of the first and second construction elements includes through-holes and grooves on two major surfaces, respectively, of the construction element. A thickness of each groove is substantially the same. At at least one end of each groove, an edge of the groove is curved. The pin includes a body having a cavity and a member. A first portion of an edge of the member is curved, and a second portion of the edge of the member is straight. A thickness of the member is not larger than the thickness of each groove. The member of the pin is fixed in place in one of the grooves of the first construction element when the first and second construction elements are coupled by the pin and the fastener so as to constrain the pin from rotating with respect to an axis of the body of the pin.

Disclosed are a connector and an assembly toy set including the same. The connector includes a body having an upper surface, a lower surface, and a plurality of side surfaces, a first coupling part disposed on at least one of the plurality of side surfaces, and a second coupling part disposed on the upper surface, the lower surface, or the side surfaces, except for the surface on which the first coupling part is disposed. The first coupling part has a column shape that protrudes from the surface on which the first coupling part is disposed and has a joint ball for joint coupling at an end thereof. According to the present invention, various connection postures may be provided by using the joint balls for joint coupling at an end of the connector. Accordingly, various desired models may be easily assembled.

The modular panel system includes composite panels with grooves integrated into both vertical sides thereof. The grooves engage the protrusions molded into all four sides of the mating element. By sliding panels onto a mating element, a room can be created. Two walls at right angles form a simple room corner. Three walls can become two adjoining rooms and other configurations. When disassembled, the panels and elements can be transported and stored out of the way, which is especially useful when used for large scale dolls, eighteen inches tall or more.
