Definitions

  • This invention relates to fences, and in particular to fences comprising posts and rails fabricated from sheet metal.
  • Such a fence may comprise no more that a plurality of spaced apart upright posts and one or more rails extending between each pair of neighbouring posts.
  • each fence panel may comprise a small plurality of rails, for example a top and a bottom rail, or top and bottom rails and an intermediate rail, supporting in-fill means such as, for example, a plurality of pickets or other upright members or one or more rigid sheets.
  • the present invention is applicable to all such fence constructions, being directed essentially to the affixure of the posts to the rails.
  • Sheet metal fences have gained in popularity in recent times, especially when made of steel that has been pre-coated with zinc, an aluminium-zinc alloy, or other corrosion resistant coating and finish painted by the materials supplier, because of their long life and attractive appearance.
  • an object of the present invention is to simplify the erection of sheet metal fences by providing for the ready affixture of the rails to the posts without the need for screwed fasteners to pierce the respective components.
  • a secondary object of the invention is to provide for such affixture by means which not only permit a rail to extend horizontally from a nominally vertical post but also permit for a degree of departure from horizontal ity in either sense, so as to better adapt pre-fabricated fence components for use in fences on sloping or undulating sites.
  • the invention consists in the combination of a fence post and rail comprising a sheet metal post shaped so as to define a longitudinally extending recess in a side of the post, post coupling means formed in the metal defining the recess, rail supporting clip means comprising clip coupling means in snap engagement with the post coupling means, and a sheet metal rail having an end portion disposed within the recess in snap engagement with the rail supporting clip means.
  • the invention consists of a method of attaching a rail to a post in a fence comprising providing:
  • the post shaped from sheet metal so as to define a longitudinally extending recess in a side of the post;
  • the rail formed from sheet metal, in the form of an inverted channel sectioned body having a channel web portion and two channel flange portions;
  • - post coupling means comprising two arcuate or chevron shaped slots, one opposite the other in opposing side faces, in the metal defining the recess;
  • - clip coupling means comprising two tongues on a rail supporting clip means adapted to in use hook over lower edges of the respective slots; and locating the tongues into the slots and locating the channel flange portions into the rail supporting clip means.
  • the post coupling means comprises two arcuate or chevron shaped slots, one in each of two opposite side faces of the recess, and the co-acting clip coupling means comprises two tongues on the clip means adapted to hook over lower edges of the respective slots and two bosses are provided on the clip means and adapted to snap under the upper edges of the respective slots when the tongues are fully homed, so as then to prevent the clip means rising and the tongues from retracting from the slots.
  • the clip coupling means remain in engagement with the post coupling means while permitting some rotation of the clip, and of a rail engaged with it, about a horizontal axis extending from one said side face of the recess to the other.
  • the channel flange portions of the rail have inturned lipped flanges extending along their free edges and the clip means defines two troughs with non-return detent means in one side wall thereof.
  • the clip means and the rail are so dimensioned that the edge margins of the channel flanges including the lipped flanges may be inserted into the respective troughs, during which insertion the resilient lipped flanges are deformed as they ride over the detent means, and following which the rail is gripped by the clip means due to the total or partial return of the lipped flanges to their undeformed shape and consequent inability to move past the detent means in the return direction.
  • Figure 1 is a plan view of a fence post.
  • Figure 2 is a plan view of the post of Figure 1 with rail supporting clip means in place.
  • Figure 3 is a sectional view taken on line 3-3 of Figure 2, but with fence rails in place.
  • Figure 4 is a view similar to Figure 3 taken on line 4-4 of Figure 2.
  • Figure 5 is a side elevation of clip means appearing in Figures 2, 3 and 4 drawn to a larger scale.
  • Figure 6 is a front elevation of the clip means of Figure 5.
  • Figure 7 is a detail view drawn to a larger scale of a fragment of the post of Figure 1 , when viewed along the arrow marked 7 in Figure 1 , showing post coupling means thereof.
  • Figure 8 is a diagram to a larger scale of the post coupling means of Figure 7 indicating the interaction of the clip means of Figures 5 and 6 therewith.
  • the illustrated embodiment comprises an intermediate fence post 10 supporting two fence top rails 11 extending in opposite directions from the post 10.
  • the post defines two rail receiving recesses (14), one on each side thereof.
  • the recesses are functionally identical and the mode of affixture to the post is the same for each rail.
  • no attempt is made to distinguish between the duplicated components herein.
  • the description applies with equal force to an end post which may have only one recess with a rail or rails extending in only one direction therefrom.
  • the post 10 comprises a web 12 and two hollow flanges 13 defining longitudinally extending recesses 14 on opposite sides of the post.
  • the post 10 may be cold roll-formed from a single sheet of pre-painted steel, with the edges 27 securely affixed to the web 12 by clinches 28 applied in an operation such as that described in Australian patent application 50457/93 or 77725/94 immediately after roll-forming.
  • the side walls of the recesses 14 are each pierced by a chevron shaped slot 15 near the top of the post 10, making four slots in all.
  • the two slots 15 of each recess 14 constitute the post coupling means in respect of the affixture of a corresponding one of the top rails 11.
  • the recess side walls may be pierced by a series of equally spaced apart slots, one above the other, to provide for the affixture of further rails below the top rail.
  • the clip means of the embodiment now being described comprises a single clip 16 which is cut and press-formed from one piece of sheet metal. Each clip 16 is adapted to bridge across a recess 14, and has clip coupling means adapted to engage the slots 15 adjacent its ends.
  • each clip 16 comprises a generally W-shaped strip (see Figs. 5 and 6) comprising two inner limbs 17, two outer limbs 18 and short upper and lower junction pieces 19 and 20 respectively.
  • Each inner limb 17 is stepped at 21.
  • each adjacent pair of inner and outer limbs and the junction 20 connecting them define a trough 29, and the step 21 constitutes non-return detent means in a wall of that trough.
  • Each outer limb 18 has a tongue 22, which is slit and displaced from the limb together with a boss 23 pressed from the plane of the limb.
  • the tongue 22 and boss 23 are so sized and positioned relative to each other that if a clip 16 is inserted downwardly into the recess 14 of a post furnished with a pair of slots 15, the tongues 22 may simultaneously pass through the slots 15 of the recess until the junction of each tongue and outer limb 18 comes up against the lower edge of the corresponding slot. At that time the bosses 23 just clear the upper edges of the slots and allow the clip to snap into place, as may best be seen from Figures 3 and 4.
  • Each rail 11 is an inverted channel section having a channel web 31 and two channel flanges 32.
  • Each channel flange 32 has an inturned lipped flange 24 extending along its free edge.
  • the rail may incline upwardly or downwardly by about 15°.
  • the single clip 16 may be replaced by two clips each able to independently engage the post coupling means, for example two clips each comprising substantially half of clip 16 minus the central portion above the steps 21.
  • the post and rail join is visually neat, with the exposed faces of the posts undisturbed by fasteners.
  • the slots in the recesses open into the flange hollows, so limiting visibility of the slots and tongues in the constructed fence.

Abstract

L'invention porte sur un assemblage piquet et traverse pour une clôture, ces deux éléments (10, 11) étant fabriqués à partir d'une tôle métallique. Le piquet (10) est configuré avec un évidement (14) s'étirant longitudinalement sur un seul côté ou sur les deux à la fois. Des fentes (15) ménagées dans l'évidement permettent à une attache (16) de s'y fixer afin de soutenir la traverse. La version préférée comporte une attache enclipsable ajustée tant à la traverse (11) qu'au piquet (10), mais autorisant une rotation de l'articulation, de sorte qu'il est possible d'édifier la clôture avec sa traverse fortement inclinée à partir d'une perpendiculaire au piquet.
