A joint for ready-to assemble furniture including a mortise in a first of two workpieces, an insert for the mortise and a fastener, such as a screw for securely joining the workpieces. The fastener receiving insert has a curved front wall corresponding to a curved load-bearing face of the mortise. An insert bore penetrates the insert for receiving the fastener, and a cover cap on the insert covers the insert member and the mortise from view when two workpieces are joined. The second workpiece has a pre-drilled bore which receives the threaded end of the fastener. The fastener is screwed into threaded engagement with the pre-drilled bore in the second workpiece to securely joint the two workpieces. A plurality of embodiments of the joint and a method of joining the workpieces also are disclosed.

A device for fixing an element to an outer surface of a support wall of a hollow body in proximity to a first partition wall of this body perpendicular to said surface, including a bolt which extends through a part of the element and said support wall and cooperates with a nut bearing against an inner wall of the hollow body, parallel to said outer surface, wherein the nut is constituted by a plate in which is provided at least one tapped hole and to which is elastically fixed a fastener extending through an opening in the first partition wall. This opening permits the introduction of the plate, the fastener being itself elastically fixed to the first partition wall.

A structural joint for a space frame having connecting members or nodes and tubular structural member is provided in which the shank of a connecting bolt, whose head is located within the hollow end portion of the tube, extends through an aperture in the tube end for engagement with a threaded opening in the node. The tube shank has a longitudinally extending keyway formed therein in which a key is slidably received. A nut or sleeve having an unthreaded inner bore receives the bolt shank and has an internal keyway which receives a portion of the key to rotatably lock the nut and bolt together so that the nut may be rotated to rotate the bolt and engage its shank in the threaded opening of the connecting member.
摘要:
A concealed means for joining two abutting elements. The first element has at least an engaging surface and an access surface oriented angularly with respect to the engaging surface. An anchor means is secured within the engaging surface such that the axis thereof extends outwardly from the engaging surface. The second element also has an engaging surface that can be abutted to the engaging surface of the first element. The first element has an ingressive passage that opens through its access surface and communicates with the anchor means. The ingressive passage is oriented obliquely to the axis of the anchor means, and the actual fastening of the first and second elements is achieved by a screw means that extends through the anchor means of the first element and penetrates the engaging surface of the second element. Tightening and loosening the screw means is accomplished by driving means having a flexible shaft for negotiating the oblique intersection of the ingressive passage with the axis of the anchor means and for permitting actuation of the screw means by rotation of the shaft from exteriorly of the first element.

A support portion includes a sleeve having slots formed therethrough for gaining access to the interior of the sleeve. A threaded screw portion has the upper end thereof interconnected with a seat support and is rotatably supported within the sleeve. A nut is threaded on the screw portion and includes a laterally extending projection adapted to engage a member extending through the hole in the sleeve to prevent rotation of the nut upon rotation of the screw portion. A further screw is supported by the support portion for preventing disassembly of the mechanism.
