Abstract
Abstract The device described enables hollow, basically rectangular sections to be joined together either orthogonally or end-to-end and also to be joined to floors, ceilings, beams and the like. The device is a piece of extrusion basically U-shaped in cross-section which fits neatly into extrusions and by means of flanges with threaded grooves can either be connected directly to the extrusion or by drawing a bracing web into the grooves. The connecting piece is then joined to the other component or floor etc either by means of tightening the bracing web screw or by means of a flat metal plate which fits neatly into a groove in the main web of the connecting piece being secured there by screws and then screwing this plate, which projects out of the connecting piece, to the floor, ceiling etc. Provision is also made for a sealing agent which accommodates dimensional differences due to tolerances or dilation and also prevents transmission of sound.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
A device for connecting hollow sections which are basically rectangular in cross section in which the connecting piece (3) inserted in one end of the hollow section (1) is a section cut off an extrusion, which is basically U-shaped in cross section perpendicular to the long axis of the extrusion, and practically completely fills the space inside the hollow section (1), and the web (17) of the connecting piece (3) has a basically rectangular space in it and the flanges (5) of the piece (3) have, facing each other at the free ends, lengthwise-running grooves which are preferably in cross section in the form of 3/4 circles, whereby the connecting piece is secured to the base (2), on which the section (1) is to be fixed, by its web (17) if desired by screwing or by some other means, and whereby the hollow section is secured to the connecting piece by one single screw (9) and the connection joints are closed by a sealing agent (13) running round the connecting device and fitted into appropriate grooving on the outside of the web (17) of the connecting piece and if desired supplimented by a second (e.g. silicone) seal (14).
Claim 2
Independent Claim
198 words
A device for connecting hollow sections which are basically rectangular in cross section in which the connecting piece (3) inserted in one end of the hollow section (1) is a section cut off an extrusion, which is basically U-shaped in cross section perpendicular to the long axis of the extrusion, and practically completely fills the space inside the hollow section (1), and the web (17) of the connecting piece (3) has a basically rectangular space in it and the flanges (5) of the piece (3) have, facing each other at the free ends, lengthwise-running grooves which are preferably in cross section in the form of 3/4 circles, whereby the connecting piece is secured to the base (2), on which the section (1) is to be fixed, by its web (17) if desired by screwing or by some other means, and whereby the hollow section is secured to the connecting piece by one single screw (9) and the connection joints are closed by a sealing agent (13) running round the connecting device and fitted into appropriate grooving on the outside of the web (17) of the connecting piece and if desired supplimented by a second (e.g. silicone) seal (14).
Claim 3
Dependent Claim
56 words
A device according to claim 1 in which in connecting a cross piece, where the hollow section is to be connected at right angles to a long side of the base (2), a bracing web (7) is forced between the flanges (5) of the connecting piece and in the grooves (6) of the said flanges (5).
Claim 4
Dependent Claim
141 words
A device according to claim 2 in which the bracing web (7) is a flat piece of metal, which is perpendicular to the long axis of the hollow section and has a threaded groove which forms an acute angle with one of the transverse axes of the hollow section into which groove the screw (9) joining the hollow section (1) and the connecting piece (3) together engages and by tightening up turns the bracing web into the plane of the section, so that the opposite lying faces of the bracing web in the grooves of the flanges on the connecting piece are pressed against these flanges (5) and the wing (2) in the plane of the bracing web (7) positioned in the direction of the transverse axis of the hollow section is pressed against the wall of the hollow section (1).
Claim 5
Dependent Claim
61 words
A device according to claim 1 in which in making an end-to-end connection between the hollow section (1) and a similar section (2), the first hollow section (1) is secured to the connecting piece by a screw (15) which engages in a threaded groove (16) in a flange (18) on the connecting piece (3) parallel to the connecting piece flanges (5).
Claim 6
Dependent Claim
81 words
A device according to claim 1 in which in making a connection between the hollow section (1) and a floor a flat piece of metal (19) is inserted into and completely fills the space (4) in the web (17) in the connecting piece and projects out of one side of that side space (4) and is screwed to the floor at the part which projects out while the connecting piece (3) is also screwed to the flat piece of metal (19).
Claim 7
Dependent Claim
47 words
A device according to claim 1 in which in making a connection to a ceiling the connecting piece (3) is screwed directly on to the ceiling and an elastic sealing component (13) is incorporated and accommodates and compensates for movement of the hollow section due to dilation.
