Abstract: A construction block unit includes a construction block including a bottom plate having a rectangular shape, sidewalls attached to each side of the bottom plate via hinges, wherein the sidewalls rotate on the hinges from a position planar with the bottom plate for storage to a position perpendicular to the bottom plate to form a receptacle configured to receive and contain a weight, and a pair of interlocking portions, each at opposite sides of the construction block to fasten the sidewalls in the position perpendicular to the bottom plate. Each of the pair of interlocking portions is shaped to receive a corresponding interlocking portion of a second construction block by vertically sliding the corresponding interlocking portion into the interlocking portion.

Abstract: A construction block unit includes a construction block and a lid. The construction block includes a bottom plate having a shape, a sidewall extending perpendicularly from the bottom plate at an outer edge of the bottom plate to form a container configured to receive and contain a weight, and fasteners coupled to a top edge of the sidewall opposite the bottom plate. The lid has a congruent shape to the shape such that the lid is fastenable to the top edge of the side wall via the fasteners to enclose the container. An interlocking portion of the construction block is shaped to receive a corresponding interlocking portion of a second construction block by vertically sliding the corresponding interlocking portion into the interlocking portion, interlocking the construction block and the second construction block to prevent separation by a horizontal force.

Abstract: Interlocking plastic blocks, trademarked as PIXELBLOCKS, are configured to serve as basic pixels, i.e. picture elements, in the creation of a variety of two- and three-dimensional graphic artifacts. The pixel blocks can be made in various equilateral polygonal cross-sectional shapes of designated length, typically embodied in an equilateral cube shape. All side facets in the outline of cross-sectional shape, e.g. four facets of the cube, are made identical, each facet configured with a tongue alongside a groove in a symmetrical complementary configuration such that adjacent blocks can be interlocked together to form one- and two-dimensional arrays; thus pixel blocks of uniform depth front-to-back can form two-dimensional artifacts. A 3D embodiment includes posts and post holes for Z axis attachment to form multi-layer three-dimensional artifacts.

Abstract: Interlocking blocks are configured to serve as basic picture elements and beams ("pixels and sticks") for creating a variety of two- and three-dimensional graphic artifacts. The pixel blocks have a substantially square cross-section and may be made in cubes or in beams of various length. The four sides of the square cross-section are made identical, each side defining a tongue alongside a groove in a symmetrical complementary configuration such that adjacent blocks can be slidingly interlocked together to form one- and two-dimensional arrays; thus cubes, or blocks of uniform length, can form two-dimensional artifacts and blocks of various lengths can form three-dimensional artifacts. By utilizing the blocks in a variety of visual properties such as color and light transmission, quantities of the blocks and/or beams may be interlocked together to form pictures, graphics patterns, and other artifacts.
