Benefits of technology

[0010]In one aspect stringer sides are angled inwardly, wherein stringer sides hold the fence boards in place for fastening the fence boards to the stringer sides. In this aspect each fence board is firstly inserted through a board slot in an upper stringer and then secondly inserted into a vertically corresponding board slot in a lower stringer, wherein the fence board is then held in place via a friction fit for attaching the fence board to the upper and the lower stringers. Depending upon the pressure exerted on the fence board only one of the two stringer sides adjacent each fence board may need to be so inwardly angled, however if the stringer sides are so angled for all board slots for each fence board the amount of pressure required by each such angled stringer side is minimized thereby reducing the resistance necessary to overcome to draw stringer sides substantially vertical and flush with the inserted fence boards.
[0028]This fence construction offers a number of unobvious advantages: the components are all readily manufactured from stock materials, and use stock fasteners; the boards are of natural wood or of recycled plastic of common section, being readily available in pre-cut, measured lengths at most lumber retailers; on-site erection is readily carried out by a single person, with no particular skill requirements once the fence posts are mounted in the ground (usually in concrete); The erected fence is a stiff, strong structure with good resistance to weather attack (e.g. no rusting) of the fastening screws, and with the concealed outer face portions of the fence boards being kept dry within the stringer; and no rotting of aluminum post footings; in case of damage to the fence, individual boards are readily released from their attachment to the stringers, and readily replaced. Where a tubular fence post is damaged the provision of a tightly fitting sleeve, enables the damaged post to be severed, the tightly fitting sleeve applied to the remaining stub of the original post, and a new fence post mounted to the sleeve. This provision avoids the undue labour of excavating the cement footing, and pouring a new footing. The use of an internal sleeve is preferred, for protective purposes. Post caps to seal off the top ends of the fence posts are preferred, which may be of metal or plastic, and of a variety of styles.
[0029]The novel features of the stringers, brackets and fence posts facilitate ready installation of these elements, and the ready installation or replacement of fence boards which suit a ‘do-it-yourselfer’.

Problems solved by technology

These types of fences are labour intensive, and over time, when servicing is required, such as the replacement of some of the boards, the removal of defective boards can be most difficult.
Also, where any hardwood is used, the disassembly of damaged boards can prove exceedingly difficult, time consuming and destructive.
A major drawback to this fence is the use of standardized, prefabricated notched boards.
In case of damage to the fence in future years, the particular precision-cut notched boards may not be readily available, while the manner of assembly, without the use of positive fasteners may lead to board movement under windy conditions, and the generation of objectionable noise, and general lack of fence strength.
Further due to the manner of board attachment, the addition of a new fence board or boards requires the removal of at least one stringer from both its supporting fence posts, to enable the removal of the old board and the insertion of the new board, and the return of the stringer into attached relation with the posts, a most difficult and burdensome task.

Embodiment Construction

[0081]Referring to FIGS. 1, 2 and 11, a fence stringer 10 is cut to length from stock, to extend between two fence posts 12. The stringer 10 is of inverted U-section, with opposed stringer sides 14 and intermediate adjoining portion 16. The intermediate adjoining portion 16 has two sets of board slots, 18, 19 a first set of board slots 18 and a second set of board slots 19 located flush with inside surfaces 15 of opposed stringer sides 14, such that the outermost sides 20 of the board slots 18, 19 are flush with the inside surfaces 15 of the stringer sides 14. A series of equi-spaced bracket attachment apertures 22 extend longitudinally along the intermediate adjoining portion 16, preferably along the longitudinal centre line of the intermediate adjoining portion, between the first set of board slots 18 and the second set of board slots 19, the bracket attachment apertures 22 being sized to receive a fastener, preferably a carriage bolt 23 (see FIG. 2).

Abstract

A stringer for an off-set board-on-board fence having an inverted U-section elongated body having two mutually opposed sides depending from an intermediate adjoining portion having laterally off-set and longitudinally over-lapping first and second sets of spaced board slots extending flush with inside surfaces of the opposed sides for attaching fence boards of predetermined cross-section flush to the inside surfaces of the opposed sides of the stringer. The stringer has board fastening apertures in the opposed sides of the stringer to fasten the fence boards flush with the inside surfaces of the opposed sides. The stringer has a plurality of bracket attachment apertures, preferably square, arranged longitudinally from end to end, between the first and second sets of board slots for attaching post brackets at each end of the stringer. A stringer support of each opposing bracket is within range of one bracket attachment aperture at each end of the stringer.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of U.S. patent application Ser. No. 13 / 243,579, filed Sep. 23, 2011, which claims the benefit of the filing date of Canadian Patent Application No. 2717783, filed Oct. 15, 2010, both of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]This invention is directed to a fence construction, and in particular to a fence having horizontal stringers with vertical boards, and in particular a board on board fence, also known as an alternating board on board fence.BACKGROUND OF THE INVENTION[0003]The board on board fence or alternating board on board fence is a very well known and widely used construction, usually being made entirely of wood, with fence posts set in cement in the ground, with a pair of horizontal wooden stringers nailed to the posts, with fence boards mutually spaced and secured in staggered relation on alternate sides of the stringers by nailing,...
