Abstract

Abstract A connecting member comprising an elastically deformable, tubular plug (1) slitted at the ends for interconnecting pairs of building components (9a,9b), which have coupling holes (8a,8b) to receive the ends of the connecting member, has apertures (3) in the plug wall between the slits (2), and the plug wall is formed with lengthwise extending clamping wedges (4) between the apertures (3), said clamping wedges having inclined faces which slope towards the ends of the connecting member and causing the connecting member to be compressed at the center and be expanded at the ends when it is pressed into a pair of co-axial holes in adjacent building components. The connecting member may in particular be formed with an annular flange (5) and end beads (6a,6b) which fit in corresponding annular grooves (7) in a pair of adjacent components (9a,9b).

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 140 words
A connecting member for interconnecting a pair of components in a building set, said member comprising: a tubular plug having a cylindrical outer surface made of an elastically deformable material; a pair of lenghtwise slits extending from each end of said plug along a first axial plane; a pair of opposed, lenghtwise extending apertures disposed in said first plane in the middle portion of the plug; two pairs of opposed wedges disposed on said plug cylindrical outer surface, said wedges extending lenghtwise along a second axial plane perpendicular to said first axial plane, the two wedges of each pair being disposed symetrically on opposite sides of a third plane disposed generally in the middle of the plug perpendicular to the axis of said plug, said wedges tapering inwardly from the middle portion of the plug toward the opposite ends thereof.
Claim 2
Dependent Claim 140 words
A connecting member for interconnecting a pair of components in a building set, said member comprising: a tubular plug having a cylindrical outer surface made of an elastically deformable material; a pair of lenghtwise slits extending from each end of said plug along a first axial plane; a pair of opposed, lenghtwise extending apertures disposed in said first plane in the middle portion of the plug; two pairs of opposed wedges disposed on said plug cylindrical outer surface, said wedges extending lenghtwise along a second axial plane perpendicular to said first axial plane, the two wedges of each pair being disposed symetrically on opposite sides of a third plane disposed generally in the middle of the plug perpendicular to the axis of said plug, said wedges tapering inwardly from the middle portion of the plug toward the opposite ends thereof.
Claim 3
Dependent Claim 37 words
A connecting member, as claimed in claim 1, wherein the middle portion of the plug is provided with an annular flange, and wherein the apertures in the middle portion of the plug extend through the said flange.
