Abstract
A fitting for detachably interconnecting two walls of an item of furniture at an angle to one another. The fitting comprises a bearing body locatable in one wall, which body has two bores formed therein, a rotatable torsion bolt being located in one bore and a portion of a tightening bolt in the other bore. On its external surface the torsion bolt is grooved. The two bores communicate with one another. In use, the head of the tightening bolt engages with the groove in the torsion bolt, and the opposed end of the tightening bolt engages in the other wall whereby rotation of the torsion bolt locks the tightening bolt in position and causes said walls to be interconnected.

A fitting for detachably interconnecting two walls of an item of furniture at an angle to one another, comprising a bearing body locatable in a recess in a first of said walls, said bearing body having two bores formed therein extending at an angle to one another, said bores communicating one with the other, a torsion bolt rotatably journalled in the first of said bores and carrying, on one of its end faces, tool receiving means, said torsion bolt having an external surface, said external surface being channelled to form a first groove, and a tightening bolt locatable in the second of said bores in said bearing body, said tightening bolt comprising a securing portion engageable in the second of said walls, a guide portion engaging at least partially in said second bore and a head portion, said head portion co-operating with the surface and at least a part of the perimeter of said grooves in said torsion bolt, whereby said co-operation draws said head of said tightening bolt into said bearing body causing said two walls to be connected and causing said tightening bolt to be locked in position relative to said bearing body, said torsion bolt being provided with a projection extending laterally from the end region of said torsion bolt provided with said tool receiving means, said bearing body being provided with at least one upstanding projecting portion around the periphery of said bore receiving said torsion bolt whereby said projection on said torsion bolt co-operates with said at least one upstanding projecting portion formed on said bearing body to limit rotation of said torsion bolt in said bore.
A fitting for detachably interconnecting two walls of an item of furniture at an angle to one another, comprising a bearing body locatable in a recess in a first of said walls, said bearing body having two bores formed therein extending at an angle to one another, said bores communicating one with the other, a torsion bolt rotatably journalled in the first of said bores and carrying, on one of its end faces, tool receiving means, said torsion bolt having an external surface, said external surface being channelled to form a first groove, and a tightening bolt locatable in the second of said bores in said bearing body, said tightening bolt comprising a securing portion engagable in the second of said walls, a guide portion engaging at least partially in said second bore and a head portion, said head portion co-operating with the surface and at least a part of the perimeter of said groove in said torsion bolt, whereby said co-operation draws said head of said tightening bolt into said bearing body causing said two walls to be connected and causing said tightening bolt to be locked in position relative to said bearing body, said torsion body being channelled to provide a further groove located adjacent the perimeter of said first groove, the longitudinal direction of said further groove extending in the direction of rotation of said torsion bolt and eccentrically around said torsion bolt, said further groove defining a tensioning surface engaging behind said head portion of said tightening bolt, said tensioning surfaces having projections formed thereon.
A fitting for detachably interconnecting two walls of an item of furniture at an angle to one another, comprising a bearing body locatable in a recess in a first of said walls, said bearing body having two bores formed therein extending at an angle to one another, said bores communicating one with the other, a torsion bolt rotatably journalled in the first of said bores and carrying, on one of its end faces, tool receiving means, said torsion bolt having an external surface, said external surface being channelled to form a first groove, and a tightening bolt locatable in the second of said bores in said bearing body, said tightening bolt comprising a securing portion engageable in the second of said walls, a guide portion engaging at least partially in said second bore and a head portion, said head portion co-operating with the surface and at least a part of the perimeter of said groove in said torsion bolt, whereby said co-operation draws said head of said tightening bolt into said bearing body causing said two walls to be connected and causing said tightening bolt to be locked in position relative to said bearing body, said external surface of said torsion belt comprising a substantially cylindrical surface portion and an outwardly directed projection portion, said projecting portion having said groove formed in its outer edge, said first bore in said bearing body having a cross-section which is substantially keyhole shaped, whereby said projection portion on said torsion bolt engages behind said head portion of said tightening bolt.
