Abstract
A fitting for the connection of construction elements, such as wooden construction elements. The fitting is made of two identical fish-belly shaped fitting components which insert into corresponding grooves in the construction elements. Each fitting element has harpoon-like webs to engage the construction elements. Opposite to the fish-belly portion of the fitting element is a blade and upon the blade is at least two hook heads spaced apart by at least the width of one hook head. In the connected position, the fitting components face each other and the two complementary fitting components grip one behind the other at the hook heads.
Claims5
A fitting for connecting two elements to one another;
- said fitting comprising two complementary fitting components affixable to the one and the other element;
- each said fitting component comprising
- a base body having a front side;
- a blade formed on the base body;
- said blade having an upper face;
- and
- at least two hook heads formed on and projecting from said upper face;
- each of said hook heads having a length extending parallel to said upper face and parallel to said front side;
- said hook heads being spaced from one another generally parallel to said front side, at a distance corresponding at least to the hook head length;
- each said hook head being bounded by a hooking surface having a length extending generally parallel to said front side;
- each said hook head further being bounded by two sloped planar surfaces extending towards said front side from opposite ends of said hooking surface obliquely to the length of said hooking surface;
- said sloped planar surfaces being in mirror image symmetry with one another relative to a plane intersecting and being perpendicular to the length of said hooking surface, whereby during an interengaging relative motion between the two fitting components, the latter are guided towards one another by a sliding engagement of the sloped planar surfaces of one of the fitting components with the sloped planar surfaces of the other of the fitting components and wherein, in a fully interengaged state between the two fitting components, the hooking surfaces of the one fitting component are in an abutting, locking relationship with the hooking surfaces of the other fitting component.
