Abstract

Abstract Components for constructional purposes in the form of bars or columns which form male components and female components fixable thereto for coupling with connecting components to make frames of various kinds as for tables or shelving or the like, the bar or column comprising sub-columns of polygonal or octagonal-based section spaced around and integral with a central core, each subcolumn being adapted to form a male element of a joint with one or more of the female components which are provided with an opensided bore having a corresponding polygonal or octagonal-based wall and adapted to embrace a sub-column and be secured thereto at any appropriate position therealong. Columns with sub-columns of identical section form a modular unit for cooperation with a standard form of female component which may be fitted to any one of the sub-columns and be designed for locating and fixation to a standard form of frame component by spigot and socket coupling preferably so that the frame component comes flush with the female component. The female components may be fitted by screws countersunk in channels in the female components to tighten such components on the sub-columns and be designed for connection to the frame components by self-tapping screws in open-sided bores at the sides of the channels to cause them to grip the frame components.

Claim 5
Dependent Claim 73 words
Modular joint components according to claim 2, in which only one side of the wall of the bore of the female component is omitted and the sides of said wall adjacent to the lateral opening thus formed are defined by two relatively converging oblique lips and each said channel between sub-columns of the column component is adapted to accommodate one said lip and a lip of a like female component side-by-side in parallelism.
Claim 6
Dependent Claim 61 words
Modular joint components according to claim 2, in which two adjacent sides of the wall of the bore of the female component are omitted to provide the lateral opening and the two lips so that the female component can embrace a sub-column and lie at an angle of 45* to the axes intersecting the centers of the core and the sub-columns.
