Abstract
Abstract Structural members are connected by a joining device which is attached to one of the members and has an insert part projecting therefrom for insertion into a cavity in another structural member. The insert part has a shoulder arranged to lie within the cavity facing the first structural member, and a pin passes through an aperture in the second structural member to abut with the shoulder to retain the insert part within the cavity. The pin preferably has a cross-section shape so as to urge the insert part further into the cavity on rotation of the pin. The device may be attached to the first structural member by screw means.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
167 words
Means for joining structural members, comprising an insert plate, a locking pin, and means adapted for rigidly but detachably securing one end of the insert plate to a first structural member so as to project therefrom, the insert plate having the same external cross-section at each end so that it can be a close sliding fit within a cavity of similar cross-section in a second structural member, the insert plate having an aperture through which the locking pin can pass when inserted through a passage in the second structural member, whereby the plate is locked within the second structural member, the pin having a flat formed on one side, said flat being in engagement with the wall of the aperture in said insert plate and providing a cam section to the pin, whereby on rotation of the pin from a position in which the flat is in engagement with the plate on the side of the aperture remote from said one end the joint will be tensioned.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
137 words
In an article of furniture which includes abutting panels, a joint between said panels comprising a plate rigidly secured at one end to the abutment surface of a first panel, said plate being circumferentially enclosed with a close sliding fit in a cavity in the opposite abutment surface of a second panel and in the same plane as the second panel, and a pin disposed in a passage in the second panel and extending through an aperture through the plate, said pin being in engagement with the plate on the side of the aperture remote from the first panel so as to retain the plate within the cavity, the pin having a flat on one side whereby the joint can be tensioned by rotation of the pin from a position in which the flat engages the plate.
Claim 4
Dependent Claim
137 words
In an article of furniture which includes abutting panels, a joint between said panels comprising a plate rigidly secured at one end to the abutment surface of a first panel, said plate being circumferentially enclosed with a close sliding fit in a cavity in the opposite abutment surface of a second panel and in the same plane as the second panel, and a pin disposed in a passage in the second panel and extending through an aperture through the plate, said pin being in engagement with the plate on the side of the aperture remote from the first panel so as to retain the plate within the cavity, the pin having a flat on one side whereby the joint can be tensioned by rotation of the pin from a position in which the flat engages the plate.
Claim 5
Dependent Claim
56 words
A joint according to claim 2, in which an internally threaded bush is inset in the abutment surface of the first panel and is permanently secured therein against extraction and rotation, and a screw projects from said one eNd of the insert plate and engages in the bush to secure the plate to the first panel.
Claim 6
Dependent Claim
37 words
A joint according to claim 2, in which a screw extends from the plate through a passage in the first panel and into the edge of a third panel abutting the opposite face of the first panel.
Claim 7
Dependent Claim
56 words
A joint according to claim 4, in which a second said insert plate is similarly housed in a cavity in the edge of the third panel and similarly retained therein by a said pin, the screw connecting both plates through the passage in the first panel, whereby both plates are rigidly secured to the first panel.
Claim 8
Dependent Claim
64 words
A joint according to claim 4, in which a third said insert plate is housed in a cavity in an edge of the first panel so that the screw passes through the aperture in the plate and retains the plate within the cavity, the third plate being rigidly secured to the abutment surface of a fourth panel abutting the edge of the first panel.
Claim 9
Dependent Claim
58 words
A joint according to claim 6 in which the fourth panel abuts the first panel edge-to-edge, and a fourth said insert plate is housed in a cavity in the abutting edge of the fourth panel and retained therein by a said pin, a screw joining the third and fourth plates to secure together the first and fourth panels.
Claim 10
Dependent Claim
21 words
A joint according to claim 2 wherein the pin is of circular section except for the flat formed on one side.
Claim 11
Dependent Claim
14 words
A joint according to claim 2 wherein the insert plate is of plastics material.
Claim 12
Dependent Claim
20 words
Means according to claim 1 wherein the pin is of circular cross-section except for the flat formed on one side.
Claim 13
Dependent Claim
13 words
Means according to claim 1 wherein the insert plate is of plastics material.
