US Patent 10422155 Fence and fence connection apparatus and method

A connector assembly and method for constructing a no-weld pipe fence, a no-weld fence end brace, or a no-weld fence corner brace. The connector assembly includes (a) a bolt, a threaded pin, or a hinge knuckle structure which is attachable to a fence post and (b) an attachment sleeve which can be slidably nested on the end of a pipe rail or brace member. The attachment sleeve is connectable to the bolt, threaded pin, or hinge knuckle structure in a manner which allows the pipe rail or brace member to be pivoted to a horizontal position or to any other desired angle on the fence post and then locked in place.
