Patent

CA 2367676

Prior ladder levelling devices are difficult to adjust to a surface because it is necessary to unweight the ladder at the same time as adjusting. The present invention provides opposed locking brackets so that adjustment can be made by releasing a locking plate on just one bracket.

Jusqu'à présent les dispositifs de mise à niveau d'échelles présentent des difficultés d'ajustement à une surface en raison de l'obligation de soulever l'échelle et de pratiquer l'ajustement en même temps. La présente invention concerne des supports de verrouillage opposés permettant de pratiquer un ajustement par libération d'une plaque de verrouillage sur seulement un des supports.
