Abstract
A joint comprising: a tenon, a mortise for receiving the tenon, an aperture formed in one of the tenon and an interior wall of the mortise and a pin which extends from the other of the tenon and the interior wall of the mortise; wherein the aperture is a hole which is engaged by the pin in use such that the tenon is supported within the aperture, and the tenon is capable of vertical and horizontal motion within the mortise in a plane substantially orthogonal to a longitudinal axis of the pin, the motion being limited by the edges of the aperture.
Claims20
A joint comprising:
- a tenon for attachment to a building element;
- a mortise for receiving the tenon;
- an aperture having v-shaped edge formed through one of:
- the tenon and an interior wall of the mortise;
- and an upper pin which extends from the other of:
- the tenon and the interior wall of the mortise;
- wherein the aperture is engaged by the upper pin in use such that the tenon is supported within the mortise on the pin at an apex of said v-shape, and the tenon is capable of rotational, vertical and horizontal motion within the mortise in a plane substantially orthogonal to a longitudinal axis of the pin, the motion being limited by the edges of the aperture and lateral and vertical gaps within the mortise, the joint resetting to its original form following movement owing to gravitational effects on attached building elements.
A joint according to 4 claim wherein the upper pin extends from a first pin retaining aperture formed in an interior wall of the mortise to a second pin retaining aperture in the opposite interior wall of the mortise.
