20100210173 | Toy building blocks - A toy building block set includes multiple polyhedron blocks of different lengths removably attachable together. Each block includes at least a top and four side walls. At least one connector extends from the top and includes opposing interior and exterior surfaces. A recessed area is provided at the bottom of each block. Engagement projections or depressions are provided on the connector and the remaining engagement structure are provided in the recessed area of each block where they might fully or partially engage or not engage with structures on the connector. The mechanical interference engagements and resulting engagement forces provided between any two of the blocks are less than three and even less than two times the number of engagements and resulting engagement forces provided by a mated pair of the smallest polyhedron blocks of the set. | 08-19-2010 |
20100261402 | TOY BUILDING BLOCK - The disclosure discloses a toy building block that can create a cubic article by assembling a unit piece, the unit piece comprising: a plate body made of a flexible material in which an outer profile of the plate body is formed by a pair of upper and lower short sides curved inward and a pair of right and left long sides curved inward; projections provided at a corner portions located on one of diagonal lines of the plate body on a plate face of the plate body at a right angle; and through holes into which the projections can be fitted, the through holes being provided at the corner portions located on the other diagonal line of the plate body. | 10-14-2010 |
20110045733 | Block Toy - By a combination of a plurality of blocks | 02-24-2011 |
20140120798 | Stackable building block array - A stackable building block composed of a plurality or array of spaced apart hollow cone elements. All of the cones are identically configured and have an equal sided polygon cross-section. The cones are attached at their bases to form the array and may include shaped internal ribs to define a stacking height limitation. | 05-01-2014 |
20140256211 | Pairing Block set and toy block thereof - A pairing block set having a Right-hand Wedged Block and a Left-hand Wedged Block, each of mutual, mirror symmetry, is provided. Each may optionally incorporate a system of eight abutment points to each engaged Studs on its mating blocks upon assembling. By providing two different layouts—one for the odd number, and one for the even number tier toy block groups respectively, using a combination of the said pairing block set and other commonly seen Basic type of blocks for each tier groups, and after stacking up tiers of block groups by different layouts alternatingly, in a tier-to-tier mutual interlocking manner, a structurally sound assembly of oblique sided structure can be built with smoothly lined sides or walls; while leaving a plurality of Latches at both ends of the assembly, to be further interlocked with its neighboring, mating toy blocks of the intended final structure. | 09-11-2014 |
20150310785 | ADVERTISING METHODS WITH RE-CONFIGURABLE BEVERAGE SLEEVE - Combination devices that are adapted for marketing and promotion and use a sleeve for insulating beverage containers that is transformable into a toy module, building block, and/or geometric shape. | 10-29-2015 |
20150352458 | BUILDING BLOCK INCLUDING A DUAL GENDER CONNECTOR - Disclosed are implementations of a hollow three-dimensional structure with a plurality of external faces. At least one of the faces includes a connector. The connector may be configured to engage with an other connector of an other building block. The hollow three-dimensional structure may include a connector with a fastener base. The connector may include a male connector portion and a female connector portion both attached to the fastener base. The male portion and the female portion, together as the connector, makeup a dual gender connector that connects to another dual gender connector upon an application of force. | 12-10-2015 |
