The present application relates to a hard-core and soft-shell toy building blocks set, comprising polycarbonate matrix having tenon on its top and several mortise holes on its bottom; the outside surface of said polycarbonate matrix is cladded with thermoplastic polyurethane elastomer rubber layer. Said hard-core and soft-shell toy building blocks set provided in the this embodiment unitizes both conventional hard and soft kinds of cordwood toy by cladding thermoplastic polyurethane elastomer rubber layer on the outside surface of polycarbonate matrix, learning strong points from both to overcome their weaknesses, it produces high bounce ability, high resistance to wearing, bending, high temperature and oxidation, particularly, it is well worth mentioning that the new product is nonpoisonous, non-absorption of water and oil, no harm to health of children.

A system and method for an amusement construction system offering simple, safe, and efficient features and solutions unavailable in any other amusement construction system. An anchor body supports one or more extensions, each extension may include one or more semi-flexible loops. The loops are semi-flexible in that they may be deformed to pass through another semi-flexible loop while springingly returning to the undeformed state which is rigid enough to maintain a desired level of coupling. A decoupling strength is related to how easily the semi-flexible loops deform sufficiently to pass through a loop to which it is coupled.

A system or kit using elastomeric blocks for self-directed, multi-modal play is described herein. In a first example, the kit includes at least one geometric block made out of an elastomeric material with at least one hole and a faceted geometry. Variations in size, shape, and number of the at least one hole may change the performance of the kit when in use. In another example, the kit includes at least one elastomeric block with at least one hole and at least one connecting post. The at least one connecting post connects to at least one elastomeric block by being inserted into at least one hole in the block; the elastomeric material of the block clutches the connecting post. The properties of the kit enable multiple modes of play beyond simple stacking and construction, allowing the depth and complexity of play to mature and adapt to any age and ability.

An eraser comprising an eraser part 1 made from a relatively elastic material having eraser properties, and where the eraser further comprises a connector part 4 made from a relatively firm material, and wherein the connector part 4 has a first connection surface 8 provided with one or more first coupling parts 7 configured for interconnection with another element, and where said connector part 4 is embedded in a cavity 2 arranged in the eraser part 1 in such a way that said first connection surface 8 faces away from said cavity 2.

The invention relates to an assembly of one or more pegboards and beads, adapted for modular connection to each other and other components.

A set of toy construction blocks that are molded from a thermoplastic elastomer. This enables each of the blocks to elastically stretch in any direction by at least ten percent. Each toy construction block has a main body with a top surface and a bottom surface. One or more male connector protrusions extend from the top surface. One or more female connector receptacles extend into the bottom surface of the main body. At least one internal chamber is molded within the main body. The internal chamber is separate and distinct from the female connector receptacles. The internal chamber does extend into the male connector protrusions. Each internal chamber can be empty or can be filled with a fill material that does not inhibit the pliability of the main body. The fill material can be liquid, gel and lubricated particles and is preferably visible through the molded thermoplastic elastomer.

A toy construction kit is disclosed. The construction kit comprising a plurality of flexible construction pieces, each of said flexible construction pieces comprising bendable rod made up of a metal wire with a plastic surrounding the metal wire. In one embodiment, the plastic wire is flexible, said plastic surrounding said metal wire forming an elongated structure. Disks are spaced along the length of rod.

To provide a block that makes connection possible even using a flexible material.

The present invention relates to an assembled block set (500) that can be assembled from assembly blocks (100) formed from elastic materials, from rigid materials, or from an elastic material and a rigid material. Through-holes are formed in the assembly blocks (100), and assembly is possible using assembly stick blocks that pass through the through-holes in the blocks (100).

A construction kit including a plurality of construction assembly pieces each comprising a resilient half rod. The half-rod comprises a rod divided in half longitudinally and having a set of teeth. The set of teeth comprises teeth disposed at intervals along a longitudinal length of said half-rod located in alternate planes to either side of a longitudinal mid-plane of the rod. The teeth are configured to provide a snap-fit interlock with a corresponding set of teeth on the half-rod of an edge of a second corresponding construction assembly piece to define a full, preferably circular cross-section, rod where the two assembly pieces interlock. Each construction assembly pieces defines a flexible plastic rectangle partly open along one edge to allow the rectangle to be flexed further open, for modeling structures having fluid shapes.

A modular semi-rigid body construction toy containing a plurality of articulation and accessory attachments to a base body made solely out of a flexible semi-rigid foam material. The toy's base body and accessories contain internally molded geometry to achieve movement and articulation between the accessory pieces and the toy's main body. The model also contains connecting links made out of the same flexible foam connect multiple flexible base bodies to create larger articulated flexible toy systems. The modular semi-rigid body construction is built with accurate aesthetic appearances representative of real-world structures, models, and machines.
