Definitions

• Figure 2 illustrates the fixing device 1 and screw 2 in the position where the device has been passed so far into the hole 5 that the flange of the collar 7 is brought into engagement against the front of the -board 4.
• Figure 3 By pressing on the screw 2 the toggle 6 has been displaced through the hole 5 in the board 4 and out of engagement with the slot 23 in the collar 7, such that when the toggle leaves the hole 5 it is caused to assume the illustrated position by the bias of the spring 8.
• the screw 2 is now loosely disposed in the fixing device and can be withdrawn from it.
• the toggle 6 is brought into compressive engagement against the back of the board 4, as illustrated in Figure 4.
• the associated collar has an unillustrated expan- sion on the flange side of the through hole 18, and the outmost turn of the spring 8 has at one end portion a corresponding diameter increase, which also increases the cost of the spring.
• the spring is insert ⁇ ed in the collar from the flange side," the expanded por- tion of the spring being fitted into the expanded portion of the hole and the spring locked to the collar by a metal washer being pressed into the expanded portion of the hole.
• the free spring end is then taken through the hole in the toggle, which also has an expansion on the upper side of the toggle, which is not illustrated in the patent specification.
