The invention relates to children's construction kits for assembling building toys from connecting elements. The technical result is an increase in functional capabilities, permitting the assembly of simple and complex spatial constructions with dynamic properties. This technical result is achieved by virtue of a building toy consisting of a set of flat shape-forming and decorative modular elements made of a flexible resilient material and having fastening elements attached to the surfaces thereof, said fastening elements forming detachable joints capable of holding together connected portions of the surfaces, wherein each of the fastening elements takes the form of the centre of axial rotation of at least the held portion of the surface of a connected modular element, and each of the shape-forming modular elements has on its opposite surfaces at least one coaxial pair of fastening elements which are rigidly interconnected and have oppositely oriented mating surfaces.

A panel and a system for use in building a lightweight structure are provided. The panel, made of a film or a sheet capable of being curved or bent with fingers, includes a body in a geometric shape circumscribed by straight or curved edges, and at least one joint formation along the edge for panel connection. The joint formation has tabs separated by at least one gap. Each tab expands bilaterally and proximally from the body at its base, and each gap is positioned along the edge so as to accept the base of the tab. The joint formations along the edges of varied curvatures are alignedly, hingedly, and detachably interlocked with each other by twisting the panels with fingers to individually hook the tab at the gap. The panels are assembled into geometric structures having flat or curved faces.

The present invention relates to a straightly assembled block comprising engaging assembly means configured in male and female types, first ends of which can be coupled to each other, such that male and female piece blocks can be assembled by connecting the same to each other straightly, and the engaging assembly means are improved such that wear is prevented in spite of repeated separation/coupling, thereby maintaining continuous assembly power. To this end, the male and female piece blocks have engaging assembly means, first ends of which protrude in arc shapes, and the second ends of which are coupled to each other. Alternatively, connecting blocks have engaging assembly means formed on both ends thereof in different types. The engaging assembly means formed on the piece blocks or on the connecting blocks comprise a recessed portion and a protruding portion. Each of the recessed portion and the protruding portion has a guide means and a coupling means provided on both coupling surfaces thereof, respectively, the coupling means being guided along the guide means so as to engage, such that the same are connected on the same straight line. An incision hole for an elastic action is formed from a corner of the recessed portion toward the interior, on which a rotating shaft is formed, such that, when the protruding portion is guided and coupled, the incision hole is elastically operated so as to widen the recessed portion in the leftward/rightward outward direction, thereby preventing wear of the engaging coupling means.

A building block includes a main body comprising a plug module and a socket module. The plug module includes a plug body, a plug protruding from one side of the plug body and defining a first chamber, a number of first magnets arranged within the first chamber, and an insulating protrusion formed on a bottom of the first chamber. The socket module includes a socket body defining a second chamber, a number of second magnets arranged within the second chamber, and an insulating recess defined in a bottom of the second chamber. The first magnets and the second magnets are arranged in such a way that the first magnets of one of two building blocks are able to be magnetically connected to the second magnets of the other one of two building blocks.

A toy building component is disclosed. The toy building component includes a first body portion formed from soft, flexible material and a second body portion formed from a hard, resilient material that is coupled to the first body portion. One of the first body portion and the second body portion comprises a mounting component that extends from the other of the first body portion and the second body portion, and the other of the first body portion and the second body portion forms a protective casing around the toy building component. The different materials have different properties, and in some embodiments, different colors. The portions may be co-molded together to form the building component.

The invention provides a toy building brick made of a soft material and joinable to at least one other building brick. Additionally, disclosed is a solid building brick system of a soft elastic material, which enables the detachably joining of said bricks with each other, allowing the assembly of structures whose dimensions exceed the state of the art and, maintaining the firmness in said structures.

A kit and components for creating an elastic band model includes a form including at least one band retaining member. Elastic bands of different colors are assembled to the form using the band retaining member to hold the a plurality of linked elastic bands in place. The elastic bands fill out the form to create the shape and look of the model. The forms are part of a kit that includes the forms applicable to each unique model along with other components unique to that models shape and appearance.

The present invention relates to a hinge connection comprising a male member applied on a base plate, and having protrusions provided to be hinged and resiliently fitted between a pair of female members applied on a further base plate. The male member of the hinge connection is being formed by two parallel male legs, wherein each leg comprises protrusions comprising cogs or cut teeth. The female member is formed by two parallel female legs and each of the female members comprises a through hole for engaging said protrusions of the male legs. The present invention further provides construction elements comprising the hinge connection members of the instant application. In a particular embodiment such construction elements are stackable, and allow the construction of complex three-dimensional structures without loss of flexibility.
