Abstract
Provided is a braking system for use with an extension ladder having a base section and a fly section movable relative to the base section via an adjustment rope. The braking system includes a first and a second position. When tension is applied to the rope, the spring mechanism allows upwards or downwards movement of the fly section relative to the base section. When tension is removed from the rope, the spring mechanism slows or resists upwards or downwards movement of the fly section relative to the base section regardless of the fly section's position relative to the base section.
Claims20
An extension ladder comprising:
- a base section;
- a fly section slidably coupled to the base section;
- a rope;
- and
- a brake assembly comprising:
- a pulley;
- and
- a resilient member coupled to the pulley, wherein the resilient member provides a force on the pulley,
- wherein the brake assembly is configured to:
- allow upwards or downwards movement of the fly section relative to the base section when a tension is applied to the rope;
- and
- slow or resist upwards or downwards movement of the fly section relative to the base section regardless of the fly section's position relative to the base section, upon removal of the tension from the rope.
