<p>The anchoring down weight consists of a first, square plate (2) which is fastened to a second plate (3) which is in the form of a right angled, equilateral triangle. The plates are joined so that the lengthwise edges of the surface of the second plate (3) fastened to the first plate (2) run parallel to two edges surfaces of the square plate. The second plate (3) is positioned a little sideways by an amount equal to half the plate's thickness towards the centre plane of the two edge surfaces. The second plate (3) has a hole (10) in two of its sides. The identical holes have sides (11, 12) running at right angles from the two sides, and joined by a slanting side (13). The width of the holes (10) matches the thickness of the plates.</p> |
