Overcentre clamped ladder steady
An overcenter clamped ladder steady comprising a ladder support 1 mounted on an overcenter clamp, said clamp comprises a forward clamp half 3 and a rear clamp half 7, rotatably coupled by a hinge pin 8, each having a clamping surface 3a, 7a, a pair of trunnion plates 6 are mounted on the forward clamp half holding a trunnion 9, a T-shaped bar 10 is inserted and adjustable within the trunnion, a pair of clevis plates 11 are mounted on the rear clamp half holding a clevis pin 13 and handle 14, provided with a clevis slot 15 to receive the T-bar rotatably mounted on said pin. The ladder steady may comprise an end stop 16 which abuts a clevis plate when the clamp is in an overcenter position. The clevis plate and handle may also be provided with locking holes 17 for receiving a locking pin 19 (fig.5). Also disclosed is a method of clamping the steady to a support structure.
