Abstract:
A snap-fit type construction system comprising of:(a) various possible sets of construction elements, (b) said sets of construction elements having a male type one connection element and a female type two connection element, (c) said type one connection elements having a ridge and an indentation and type two connection elements having a groove and a projection, (d) said male type one connection elements having a pair of spaced apart ribs extending outward in a longitudinal direction from a side surface of said construction elements, a rib cavity being defined between them, with at least one of those faces of said ribs that face furthest away from said rib cavity being provided with said ridge projecting in a horizontal direction outward from said rib, running in a vertical direction up a considerable distance of the height of the bendable ends of said rib, with said ridges being provided with said indentation falling between the ends of the height of said ridges, (e) said female type two connection elements having a pair of opposed walls extending inwards in said longitudinal direction from said side of said construction elements, a recess being defined between said opposed walls and an end wall, with said recess having at free edges, an open face facing in said longitudinal direction, and two opposed open faces each facing in said vertical directions, with at least one of the sides of said opposed walls that face towards said recess being provided with said groove running in said vertical direction up along the entire height of said recess from a bottom surface to a top surface, with said groove being provided with said projection falling between the ends of the height of said grooves, (f) said ribs being resiliently bendable and substantially more bendable than said opposed walls, (g) said male type one connection element, including said ribs, said ridges, and said indentations, being of such a shape that by snap-effect are able to be received and releasably secured in said recess between said opposed walls by locating in said grooves and said projections of said female type two connection element, (h) whereby said male type one connection element and said female type two connection element may be used to connect different sizes and shapes of said construction elements together in a variety of orientations and for a variety of purposes.
