<p>The toggle bolt (1) has a curved elastic tongue (11) which engages a fixing hole (9) to prevent unseating rotation. It lodges in a keyhole slot (8,9) which opens out on a panel edge (10). The bolt has an enlarged circular base which is bisected (3,4) by a circumferential rectangular section groove (5). The neck (6) formed by the groove has a pair of diametrically opposed flats (7). Insertion in the slot is by lateral bolt sliding, with the groove (5) engaging the parallel sides of the slot inlet (9) and with the flats (7) parallel to the sides. Once in the bulb (8) of the slot, the bolt is rotated a quarter turn to lock in place, the base tongue (11) then engaging the slot inlet (9) to prevent further rotation.</p> |
