A fence-frame-to-post connector comprises two separate members joined by one or more fasteners separate from the members. One member is attached to the fence frame with additional fasteners separate from those used to join the two members and also separate from the connector. One of the fasteners that joins the two members of the connector can be a hinge that is preferably made by a key tab and key slot combination in which the key pivots in the keyhole.

BACKGROUND OF THE INVENTION 
       [0001]    This invention relates to a connector for making a fence-frame-to-post connection. A primary use of the present invention is in the connection of wood fence members to a metal post member. Prior art patents do not disclose an equally simple and easy to install fence-frame-to-post connection. Several unpatented fence-frame-to-post connections are in use, but none are as simple to manufacture and easy to install as the present invention. The present invention improves on the prior art by providing a connector that aligns its halves along one axis, easing installation. A preferred embodiment of the present invention improves on the prior art by providing a connector that has a hinged connection between its halves, further easing installation. 
       SUMMARY OF THE INVENTION 
       [0002]    It is an object of the present invention to provide a fence-frame-to-post connector having two separate members joined by one or more fasteners. The fasteners that join the members are separate from the members and separate from the fasteners that attach the connector to the fence frame. This allows the connection to the post to be made separately from, and prior to, the connection to the fence frame. One member is attached to the fence frame with additional fasteners separate from those used to join the two members and also separate from the connector. One of the fasteners that joins the two members of the connector can be a hinge that is preferably made by a key tab and key slot combination in which the key pivots in the keyhole. 
         [0003]    It is a further object of the present invention to provide a fence-frame-to-post connector with tabs that shield the ends of the fasteners used to join the connector members and that also align the connector members horizontally, easing installation. Still a further object of the present invention is to provide a fence-frame-to-post connector that is formed to mate with the outer surface of a cylindrical metal post, thereby easing installation. Still a further object of the present invention is to provide a fence-frame-to-post connector that has two members connected by a hinge, allowing the members to be pivoted together around the fence post. Still a further object of the present invention is to provide a fence-frame-to-post connector with a key tab and key slot combination that allows the hinge to be formed by the installer, which in turn facilitates one-handed installation on the fence post. Still a further object of the invention is to provide a fence-frame-to-post connector integral fastener retainers, either in the form of simple fastener openings or in the form of attached nuts. Still a further object of the invention is to provide a fence-frame-to-post connector that has horizontally self-aligning members by virtue of matched bend lines in the two members. Still a further object of the invention is to provide a fence-frame-to-post connector with enhanced support of the fence frame member by virtue of tabs that extend beneath the fence frame member. Still a further object of the invention is to provide a fence-frame-to-post connector that connects a metal post and a wood fence frame member. Still a further object of the present invention is to provide a fence-frame-to-post connector that eases installation on the post by snapping onto the post. These and other object of the invention are explained and illustrated below.
