Abstract
An improved shelf bracket assembly has identical bracket members. Each bracket member is L-shaped and has a mounting portion forming one leg of the L and a flange portion forming the other portion. The mounting portion has a central raised section with an opening for receipt of a flange portion of the other bracket member. Each flange also includes a dimple and a cantilever finger. The dimple cooperates with the central raised section to maintain the bracket members in an intermediate prelocked condition. The cantilever finger cooperates with the central raised section to maintain the bracket members in a final locked condition.
Claims8
In a bracket assembly consisting of a pair of bracket members, each member having an identical mounting portion including a pair of mounting wings separated by a central raised portion having an opening therein, each bracket member being mountable on the surface of a part to be assembled and said central raised portion forming a pocket with the surface of the member, each bracket member including an identical planar flange integral with and positioned at an angle slightly greater than 90.degree. relative to said central raised portion, and detent means on said flange for cooperation with the opening and the central raised portion when the flange of one bracket member is received in the pocket of the other bracket member, the improvement of detent means comprising:
- a lateral projection from the plane of the planar flange adjacent the outer end of the flange, and a flexible locking member integral with the flange positioned inwardly from the lateral projection whereby the lateral projection of one bracket member provides a temporary, intermediate holding position in cooperation with the central raised portion and opening therein of the other bracket member upon initial insertion of the flange of the one bracket member into the pocket formed by the other bracket member, and the flexible locking member of the one bracket member engages with the central raised portion opening of the other member upon full engagement of the bracket members to provide a final locking position.
