Abstract: The present application relates to a field of bedstead, particularly, relates to an inserting assembled bedstead, which includes a bed-head transverse piece, a middle transverse piece, a bed-tail transverse piece, two bedside longitudinal pieces, two bed-head supports, two middle supports and two bed-tail supports. Inserting pieces are provided at both ends of the bed-head transverse piece, the middle transverse piece, the bed-tail transverse piece and the bedside longitudinal pieces; the bed-head support and the bed-tail support are both provided with at least two sleeve pieces positioned by 90 degree relative to each other; the middle support is provided with at least three sleeve pieces adjacently positioned by 90 degree relative to each other.

Abstract: A modular assembly system comprising a plurality of structural members. Each of the structural members has at least one slot along a lengthwise side of the member. Each of the structural members is also defined by a unique spaced relationship between the predetermined slot-to-side distance and the slot-to-slot distance. The slot-to-slot distance is a whole-number multiple of the predetermined slot-to-side distance. Each of the at least one along a lengthwise side of each of the plurality of structural members is adapted to be detachably and selectively connected slot-to-slot to one of all of the slots along one of the lengthwise sides of each of the other structural members. In the preferred embodiments, the system also includes a circular support structure and an arcuate support structure.

Abstract: A system of modular assembly comprising a plurality of structural members. Each of the plurality of structural members comprises at least two slots along a lengthwise side. A first one of the at least two slots defines a first outside slot which is located nearest to a first widthwise side and a second one of the at least two slots defines a second outside slot which is located nearest to a second widthwise side. The distance between the slot axis of the first outside slot and the first widthwise side is a predetermined slot-to-side distance, and the distance between the slot axis of the second outside slot and the second widthwise side is a whole-number multiple of the predetermined slot-to-side distance. The distance between each of the slot axes of the at least two slots along one of said lengthwise sides is a whole-number multiple of the predetermined slot-to-side distance.

Abstract: A system for modular construction comprising a plurality of structural members. Each of the plurality of structural members comprises a first lengthwise side and a second lengthwise side opposite the first lengthwise side. Each of the lengthwise sides are generally parallel to each other. Each of the plurality of structural members also comprises a first widthwise side and a second widthwise side opposite the first widthwise side. Each of the widthwise sides are generally parallel to each other. Each of the plurality of structural members also comprises at least two slots along one of said lengthwise sides. Each of the slots comprise a pair of generally parallel slot sides, an open end along one of the lengthwise sides, a slot axis parallel to and disposed equally between the slot sides.

Abstract: A system for construction including a first subassembly, a second subassembly, and a connecting member. The first subassembly comprises a plurality of first structural members, each of which includes a plurality of first member sides. At least one of the first member sides includes a first member slot having a first member slot axis. Further, at least one of the first structural members of the first subassembly has at least two first member slots. Each of the first structural members of the first subassembly is detachably connected slot-to-slot to at least one other first structural member to produce the first subassembly. The second subassembly comprises a plurality of second structural members, each of which includes a plurality of second member sides. At least one of the second member sides includes a second member slot having a second member slot axis. Further, at least one of the second structural members of the second subassembly has at least two second member slots.
