摘要： An alert mechanism (170) for use with a displaceable member of a ladder rung assembly, the alert mechanism (170) being configured to provide an audible alert when the displaceable member is displaced from the first position to the second position, wherein the at least one alert mechanism (170) includes: a pin (190); a collar (200) coupled with the pin (190) and movable relative to the pin (190) between a first collar position and a second collar position; and a detent mechanism (204) configured to hold the collar (200) at the first collar position relative to the pin (190) until a force of a specified magnitude is applied to the collar (200), whereby the collar (200) is displaced from the first collar position toward the second collar position upon application of the force of the specified magnitude.
