Abstract
Abstract Connection members for constructional systems based on two extruded sections, one having an undercut channel formation along one face, and the second section have two such channels along one face, are characterized by having a base member which fits into the single channel formation of the first section and a spaced pair of parallel side members which fit in the two channel formations of the second section to be connected to the first, securement of the correction member to the two sections joining the sections together.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
254 words
A constructional system for making joints between separate lengths which may be extruded which comprises a first length having an outwardly facing, open ended, undercut channel formation with a mouth along one face thereof, a second length having two such channels with mouths along one face thereof, a connection member having a base which is passable into an end of the channel formation along said one face of said first length and is of such form as to be prevented thereby from passing said channel mouth while movable to any desired position along the channel, securing means accessible for actuation through said mouth of said channel in said first length whereby the connection member may be secured by its base to said first length at said desired position therealong to project through said mouth of said channel in said first length, said connection member having a spaced pair of side members each extending along a respective one of a pair of parallel axes and passable in its axial direction into the end of a respective one of the two channel formations along the said one face of said second length, each of said side members having a tapped hole therethrough inclined to the axis thereof in the direction of the base thereof, and a threaded member screwed into each such hole and accessible for actuation through said mouth of the associated channel in said second length whereby tightening of the threaded members draws the second length into rigid fixed relationship with said first length.

Dependent Claim

A constructional system for making joints between separate lengths which may be extruded which comprises a first length having an outwardly facing, open ended, undercut channel formation with a mouth along one face thereof, a second length having two such channels with mouths along one face thereof, a connection member having a base which is passable into an end of the channel formation along said one face of said first length and is of such form as to be prevented thereby from passing said channel mouth while movable to any desired position along the channel, securing means accessible for actuation through said mouth of said channel in said first length whereby the connection member may be secured by its base to said first length at said desired position therealong to project through said mouth of said channel in said first length, said connection member having a spaced pair of side members each extending along a respective one of a pair of parallel axes and passable in its axial direction into the end of a respective one of the two channel formations along the said one face of said second length, each of said side members having a tapped hole therethrough inclined to the axis thereof in the direction of the base thereof, and a threaded member screwed into each such hole and accessible for actuation through said mouth of the associated channel in said second length whereby tightening of the threaded members draws the second length into rigid fixed relationship with said first length.
Claim 3
Dependent Claim
33 words
The constructional system of claim 1 wherein the free end of each of the side members has an angled surface and the tapped hole passes through the angled surface in perpendicular relation therewith.
Claim 4
Dependent Claim
16 words
The constructional system of claim 1 in which each threaded member is a pointed end screw.
Claim 5
Dependent Claim
26 words
The constructional system of claim 3 wherein the screw has a circular cutting edge on its pointed end and a hexagonal socket in its opposite end.
Claim 6
Dependent Claim
21 words
The constructional system of claim 1 wherein the channels of the second length have panel supporting ledges along the lengths thereof.
Claim 7
Dependent Claim
20 words
The constructional system of claim 4 including panels abutting said ledges and extending into the channel of the first length.
Claim 8
Dependent Claim
147 words
The constructional system of claim 1 in which said first length is an extruded rigid member having inner webs forming at least the corner portion of an inner rectangular shaped core, intermediate webs extending outwardly from at least the corners of the inner webs, and outer webs carried by the intermediate webs and defining at least the corner portions of an outer rectangular cross sectional shaped core, said first length having a longitudinal slot between the webs defining adjacent corners of one side of the outer rectangular shape of the length to form said outwardly facing open ended undercut channel, and in which said second length is an extruded rigid section having webs forming a main rectangular core and having extending from an outer face of one such web additional webs each adjacent pair of which forms one of said outwardly facing open ended undercut channel formations.
Claim 9
Dependent Claim
48 words
The constructional system of claim 7 in which at least one longitudinal slot is provided in each of at least two sides of the outer rectangular shape of the section whereby such section has at least one undercut channel formation along each of at least two faces thereof.
Claim 10
Dependent Claim
33 words
The constructional system of claim 7 in which the outer rectangular shape of the cross section of the section has sides which are equal to or are integral multiples of a unit distance.
Claim 11
Dependent Claim
22 words
The constructional system of claim 7 in which inner webs form a complete side of an inner core adjacent the longitudinal slot.
Claim 12
Dependent Claim
38 words
The constructional system of claim 7 including a cover for the face of the secondary length having the two longitudinal slots therein and said cover having webs aligned with faces of the second length adjacent the slotted face.
Claim 13
Dependent Claim
39 words
The constructional system of claim 7 in which the first length has a portion of an intermediate web extending normally outwardly from an inner web to provide a side surface normal to the base of at least one channel.
