Abstract
Interlocking clips are provided to assemble structures without the need for conventional fasteners. Structures such as fences, which may be assembled in situ, include the cooperating clips designed to provide a controlled amount of “play” between the pickets and rails of the fence to enable adjustment when racking the fences to accommodate sloping terrain. The clips are provided to interlock rails to cross members. The clips are preferably formed of a single sheet of a springy metallic material. The clips may be advantageously used to couple other types of apparatus.
Claims3
Apparatus comprising:
- a channel-shaped member having a web portion and a pair of integral sidewalls extending from the web portion;
- said web portion having at least one opening;
- a cross member inserted between said sidewalls and having a first end extending at least partially through said opening, longitudinal axes of said cross member and said channel-shaped member being transverse to one another;
- a stabilizing rib integral with and extending inwardly from said first sidewall and engaging a first surface of said cross member;
- a flange integral with and extending inwardly from a free end of said second sidewall;
- a clip having a substantially U-shaped central portion defined by first and second sidewalls joined to a curved end portion, said central portion extending inwardly into an opening in a second surface of said cross member opposite said first surface, the first and second sidewalls of said U-shaped central portion being urged toward one another as the U-shaped central portion is pressed into said opening;
- free ends of said U-shaped central portion first and second sidewalls being bent a given distance from the curved end portion to form a pair of wing portions extending away from one another and being provided with curved bends to form free ends which extend toward the curved central portion, the free ends forming an angle of less than 90° with the wing portions;
- said free ends being urged into intimate contact with the second surface of said cross member and said wing portions being urged into intimate contact with an interior surface of said second sidewall whereby said clip urges a first surface of said cross member into intimate contact with the stabilizing rib and an edge of the opening in the rail thereby maintaining the channel-shaped member, cross member and clip into intimate locking engagement.
