Multi-directional and variably expanded sheet material surfaces

Expandable surfaces made from sheet materials with slits distributed on the surface of sheet material where the surfaces expand by application of force along or/and across the surface of sheet material. The unexpanded surfaces are flat sheets, or closed surfaces like cylinders, spheres, tubes, or custom-designed organic shapes marked with pre-formed or post-formed slit designs. The expanded surfaces can be single units or modules which can be attached to one another through various means. The sheet materials range from hard surfaces like metals, to softer materials like papers and plastics, or pliable materials like fabrics, rubbers, synthetic surfaces or bio-surfaces. The slits are arranged in patterns ranging from periodic, non-periodic to irregular designs. The slits can be straight, bent, curved or irregularly shaped with even or uneven spacing. Slitting can be achieved by digital cutting or punching devices like laser-cutting, water-jet cutting, digital punching, automated dies, etc. or pre-formed when casting the sheet material. Force can be applied manually with tools or through the use of machines and special set-ups. Applications range from architectural surfaces, walls, ceilings, panel systems, structures and sculpture. On a smaller scale, applications include containers, packaging material, fabrics and human wear. On micro- to nano-scale, applications range from expandable surfaces for gauzes, band-aids, stent designs, skin grafts, semi-permeable membranes and micro-filters for various industries including purification of fluids and chemical substances.

Structural walls

A plurality of studs (14) are spaced apart relative to each other. Upper end portions (32) of the studs fit into an upper channel space (22) and lower end portions (34) fit into a lower channel space (30). The lower channel space (30) is defined in part by a pair of spaced apart sidewalls (24, 26). Screw fasteners (52) extend through the sidewalls (24, 26) and connect them to the lower end portion (34) of the stud (14). The studs (14) have upper ends that are spaced from a web (20) forming the upper boundary of the upper channel space (22). Vertical elongated slots (48, 50) are provided in the sidewalls (38, 40) of the studs (14). Screw fasteners extend through the sidewalls (16, 18) of the upper channel member (10) and then extend into and through the slots (48, 50). The heads of the screw fasteners (52) bear against the sidewalls (16, 18) when the screw fasteners (52) are tightened. This firmly connects the screw fasteners (52) to the sidewalls (16, 18), but there is no connection of the screw fasteners (52) to the upper end portions of the studs (14). When the screw fasteners (52) are tightened, there is no clamping action between the heads (54) of the screw fasteners (52) and the upper end portions (32) of the studs (14). As a result, the studs (14) are completely free to move up and down relative to the upper channel member (10), within limits established by the lengths of the slots (48, 50).
