Abstract
A spring biased prop for use with a pivot member, such as a window, hinged to a support member. The prop includes sliding tubular telescopic members each carrying a pivoted arm part for attachment to the pivot member or support member. A sleeve formed of generally friction free material, such as nylon or Teflon, is fitted between the tubular members to accommodate sliding movement of the members relative to each other.
