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.
1. A connector assembly for connecting a fence rail or brace member to a fence post, the connector assembly comprising:
an externally threaded attachment bolt or pin which is attachable to an upwardly extending fence post such that the externally threaded attachment bolt or pin will extend laterally with respect to the upwardly extending fence post;
an attachment sleeve which is slideably positionable on an end of a fence rail or brace member, the attachment sleeve having a first side opening on a first laterally side of the attachment sleeve and an opposing second side opening on a second lateral side of the attachment sleeve;
the externally threaded attachment bolt or pin being receivable by the attachment sleeve such that (i) a first end portion of the externally threaded attachment bolt or pin extends through the first side opening of the attachment sleeve, (ii) a second end portion of the externally threaded attachment bolt or pin extends through the opposing second side opening of the attachment sleeve, and (iii) the attachment sleeve can be pivoted on the externally threaded attachment bolt or pin to a selected position which can be perpendicular to the upwardly extending fence post or can be up to at least ±15° from the position which is perpendicular to the upwardly extending fence post; a
collar receivable on the upwardly extending fence post for attaching the externally threaded attachment bolt or pin to the upwardly extending fence post, the collar having at least one pair of opposing, outwardly extending attachment arms having openings provided therethrough receiving the externally threaded attachment bolt or pin;
a pair of nuts or other internally threaded attachments which are threadedly positioned on the externally threaded attachment bolt or pin and are positioned outside of and tightened against the outwardly extending attachment arms of the collar for tightening the collar on the upwardly extending fence post; and
the connector assembly further comprising at least one nut or other internally threaded attachment which is threadedly received on at least one of the first and the second end portions of the externally threaded, attachment bolt or pin to lock the attachment sleeve in place on the externally threaded attachment bolt or pin at the selected position.
2. The connector assembly of claim 1 wherein the attachment sleeve has a coped forward end which, as viewed from above, comprises corresponding semicircular, rearwardly extending indentations in a top wall and in a bottom wall of the coped forward end of the attachment sleeve.
3. The connector assembly of claim 1 wherein:
the outwardly extending attachment arms of the collar are received in a forward end of the attachment sleeve, and
the forward end of the attachment sleeve is a coped forward end which, as viewed from above, comprises corresponding semicircular, rearwardly extending indentations in a top wall and in a bottom wall of the forward end of the attachment sleeve.
4. The connector assembly of claim 3 wherein the coped forward end of the attachment sleeve has forwardly projecting side ears which, as viewed from a lateral side of the attachment sleeve, have flat forward ends.
5. The connector assembly of claim 3 wherein the radius of curvature of the semicircular, rearwardly extending indentations in the top and the bottom walls of the coped forward end of the attachment sleeve is greater than or equal to an outer radius of curvature of the collar.
6. The connector assembly of claim 1 wherein the first and the second side openings of the attachment sleeve are side slots having open forward ends at a forward end of the attachment sleeve, the first and the second end portions of the externally threaded attachment bolt or pin being receivable in the first and the second side slots through the open forward ends of the first and the second side slots.
7. The connector assembly of claim 1 wherein the attachment sleeve is cylindrical.
