Lock mechanism for retractable awning

摘要

An improved upper bracket is provided for a retractable awning of the type which includes a flexible cover sheet anchored along one edge to a vertical support surface with the opposite edge of the cover sheet being secured to a roll bar adapted to be moved toward and away from the supporting surface so that the awning can be retracted or extended respectively. The roll bar has a pair of support arms connected at opposite ends thereof which are adapted to support the roll bar at a pre-selected elevation from the horizontal surface and a pair of brace members extendable from an upper bracket to an associated end of the roll bar to hold the roll bar in an extended position spaced from the vertical support surface. A lower bracket is also mounted on the vertical support surface beneath the upper bracket and is adapted to retain the distal end of an associated brace member as well as a lower end of an associated support arm when the awning is in its retracted position. The improved upper bracket includes an automatic latch and easy locking system for securing the awning in its retracted position.
