发明名称 Ladder stabilizers
摘要 Ladder stabilizers for lateral attachment to an extension ladder for inhibiting sideways slipping and falling thereof accordingly to full safety. A long tube support made from non-rusting, a non-articulated bracing member, and a ladder side rail form an A-frame with the tube support and the side rail comprising the legs of the A and the bracing member comprising the horizontal connecting member of the A. The lock for the telescoping sections visibly indicates they are locked, this as per American National Standard ANSI A14.2-1990, par. 6.7.10, the installation being fully secured because of the technically safe locking device the telescopic tube is blocked with a spring pin. Ladder stabilizers are telescopic tubes for uneven ground and are pivotable along only the same surface of the ladder, thus enlarging the sustentation polygon for ladder support. For storage position, horizontal braces are detached and rotate about a metal attachment on the side rail of the ladder to become parallel with the ladder, the telescopic tubes are also in the same position and are firmly tied with a tension hook. This ladder stabilizer is to be added to any existing ladder extensible or non-extensible.
