A writing instrument, comprising a tubular body having a longitudinal axis with a first and a second end, and with an opening arranged in the first end; a first building block having a body part with a substantially plane surface and one or more coupling knobs extending from the substantially plane surface, and where the first building block is fixed onto the outside of the tubular body so that the coupling knobs extend away from said longitudinal axis.

An over-molded removable posable bendable toy system may have at least two end components anchored to the ends of a posable component. The over-molded removable posable bendable toy system may also have one or more body components movably engaged to the posable component to permit movement of the one or more body components between the at least two end components. An exemplary removable posable bendable toy may be removed from one toy and used in any other toy.

A structure (10) comprising two shell parts (20, 30) which are connected to each other with at least one snap connection (21), wherein the two shell parts comprise, on the inner side, mutually complementary male and female snap means (25, 35) configured to form a snap connection (21), and wherein the two shell parts have complementarily configured abutment faces that abut on each other when the male and female snap means are interconnected (25, 35); wherein the male and female snap means (25, 35) comprise an external spiral-shaped protrusion (24) configured on the male snap means, and a thereto complementarily configured, internal, spiral-shaped protrusion (34) configured on the female snap means; and wherein the external spiral-shaped protrusion (24) on the male snap means (25) is configured such that it engages with the internal spiral-shaped protrusion (34) on the female snap means (35); and that the structure (10) comprises rotation-preventive means configured such that the two shell parts are unable to rotate relative to each other when the male and female snap means are interconnected to form at least one snap connection (21).

Disclosed herein are toy building units of a toy building set. The building units comprise a sheet of a material that defines a net of a polyhedron, the sheet having a plurality of sections, each section being connected to another section with a hinge. The building units are configured to fold at the hinges from a flat configuration into a polyhedron with a hollow interior. The building units also comprise a plurality of joins on outer edges of the building unit, each join comprising one or more teeth configured to interleave with teeth of another join and releasably connect the sections of the building unit to form edges of the polyhedron. The sections, hinges and joins are all provided on one piece of the same material.

A connector element for a construction system, the construction system having first and second construction elements. The first type of construction elements comprising at least one construction element having connector knobs formed on a surface thereof and arranged in a regular two-dimensional lattice. The second type of construction elements comprising at least one construction element configured to cooperate with a connector peg to form a snap connection. The connector element comprising an elongate body having first and second ends and a longitudinal axis (A.sub.1). The first end having a first cylindrical connector portion, having an inner surface configured to form a friction fit, and an outer surface configured to form a friction fit between four neighbouring connector knobs formed on a first type of construction element. A second cylindrical connector portion configured to form a snap connection with the cylindrical connector opening of the second type of construction elements.

A method for registering one of a plurality of assembly modules operatively coupled to one another in a modular assembly system is provided. A first message including a first identifier of the assembly module is received from one of the plurality of assembly modules. A second message including a second identifier for the assembly module is transmitted to the assembly module. The second identifier is generated based on at least the first identifier. A third message including the second identifier is received from the assembly module. In response to determining that the third message is received, the assembly module is registered as a new assembly module of the modular assembly system. At least one of the receiving, transmitting, determining, and registering is performed by a control module of the plurality of assembly modules.

The Letter Cubes are block to make buildings that do not just make a statement with their rooms, walls and the like, but also make verbal statements with the blocks themselves. It has a series of three-dimensional fonts made with metal, plastic, ceramic, glass, recycled materials and other materials that magnetically, with knobs, hooks, snaps and tubes (and combinations of these and other interfaces) assemble into walls, buildings and other structures that communicate messages. These alphabets also have a series of related pieces that include numbers, punctuation and additional knobs, beams and panels that enable construction of a wide range of buildings, toys, structures and objects that are artistic, toys, games and that are otherwise useful as boxes, chairs, tables, etc. The invention comes in its own box that is assembled further to the same logic as the alphabets so it does not have packaging waste.

The invention relates to a construction unit configured to interlock with other construction units to create a variety of different shapes.

The invention relates to a toy building element (1) for the construction of an elastic structure (2), comprising a plurality of at least three consecutive chain link type individual links (4).

According to the invention it is intended that the connection (5) between the separate individual links (4) comprises a lesser reset force in relation to the bending elasticity (shear modulus G) than the reset force in relation to a tensile strength (elasticity modulus E).

With this toy building element a claw working according to the bionic principle, a fin working according to this principle or a spring joint can be constructed.

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.
