D~SCRIPTION O~ A P~EF~RE~ E~BODI~NT
The fence assembly according to the invention as shown in the acco~panying drawings, compri~es a plurality o~ fence posts 10 like the one shown in Figure 1.
Each post 10 has two lataral ~langes 12 projecting outwardly in opposite directions along all the length of the post 10. However, the flanges 12 aould extend along part only of the length o~ post 10 and they could extend at angle with respect to eaah other if desired. There may also have only one or more than two flanges 12. Each flange 12 has a ~ree edge 14 that is folded back to ~orm a ~mall channel 16.

2~i9~rl'~
Each post 10 i8 made of a single sheek of galvanized steel folded and shaped by metal forming. The posts 10 preferably have an "omega" shape a~ it can be seen in Figure 1 and 3, the long edges o~ the metal ~heet then forming the free ends 14 of the ~langes 12~ The posts 10 have a hollow section 18 separated from the ~langes 12 by a flat ridge 20 wherein the two parts o~ the metal sheet are rigidly fixed to each other, for example by welding.
A plurality of open slots 30 are made in the free edges 14. The open slots 30 extend parallel to each other through the small channels 16 in a direction preferably perpendicular to the ~ree edges o~ he ~langes 12, and are equally spa~ed from each other. To ease manufacturing, the 15 opan slots 30 can be pu~ched in the metal sheet before the folding process.
As it can he seen in Figure ~, the ~enca as~embly a:Lso comprises a plurality of screens ~0 having two lateral edges 20 42 with attaching means 44 sized and positioned to match and engage the open slots 30 of at leat two posts 10 so that in use, the screens 40 can be po~itively attached to the po~ts by engaging and locking the attaching means 44 in the open slots 30.
~5 Eaah screen is preferably a wire mesh made of wires 46 extending horizontally and vertically, and welded to~ether at every wire in~ersections. The wires of the wire mesh are made oE cold drawn steel covered by a ~ixed plastia coatin~
30 that i~ flred on the wires to be fixed permanently. However, the wires may also be made of a plastic material or any other material that is suitable for this application. The sareens may alGo be a plane metal 8heet instead o~ a wire : , 2 ~ ~ ~ 7 ~7 r~
mesh.
~ hen using the wire mesh~ as the sc~eens 40, the attaching means 44 are then consisting of the wires of the wire meshes 40 adjacent the lateral edge~ ~hereo. The distance between the ~orizontal wires of each mesh 40 is selected to be a multiple of the distance between the open slots 30 so that each horizontal wire of each loop of the wira mesh adjacent the lateral edges thereo:E may engage an open ~lot 30.
The "extarnall' wire 44 along each ~ide 42 of the wire mesh 40 is engaged in the open slot 30 o~ the adjacent flange 12 of the corre~ponding po~t by sliding the wire 44 around and behind the ~lang~ 12 and ~hen moving it in the direction in which the flange 12 extends, in order to ~ake the wire 44 to rest against the bottom o~ the small channel 16. The vertical movemenk will then be stopped by the portion of the horizonal wires which are near the wire 44 since they rest against the edge~ of their open ~lots 30.
The lataral wire 44 at the other side 42 o~ the wir~ mesh 40 is engaged the same way.
~8 can be understood, the wire mesh 40 can be oriented at any an~le with respe~t to the direction o~ the ~lange 12 and po~itioned at any height along the post6 10.
To install the fance, one has to ~ix vertically a first fence post 10 to the ground. The post 10 may be either put into a hole ~.illed with concrete or drivQn ln ~he ground with a sledgehammer. Then the later~l wire 44 of one 0~ ~he sides 42 of the screen is angaged into the channel of the post 10 a~ descrlbad above. The other side ~2 i6 2nyaged i~
another post 10 which is then ixed to the ground, preferably in another hole that may be filled with concrete after the post with the wire mesh installed on it has been inserted therein.
During installation, locking keys 60 made of rigid plastic material can be put in some of the slots 30 between the bottom of the same and the external wire 44 of the wire mesh to lock this wire ~4 firmly in the apax of the channels a~ can be sa~n in ~igure 8. This avoids a loss of preci~ion due to a slack between the posts 10 and the wire mesh 40.
Figu~es 11 and 12 shows two examples of locking keys 60.
~he wire mesh ~0 may be formed with pleated sections 50 extending horizontally along the length, to act as reinforcing ribs. The plea~ed sections 50 give a better resistance to horizontal forces that may be applied on the wire mesh. ~ein~orcement can also be achieved by using rein~orcing bars ~not shown~.
The wire mesh 40 preferably has only one oP its horizontal edges ~rom which a plurality of vertical ~pikes 70 extend, so that the wire mesh 40 can be installed with or without spikes 70 on its top edge, depending on the way the wire mesh is positioned. The spikes 70 provide oxnamentation as well as an obstacle for those who would llke to climb over the fence.
When the posts 10 and the wire meshes 40 are installed, a plastic cap 72 may be inserted on top of each of the posts 10 in order to cover the same as can be sean in Figure 4.
Figure 9 shows the bottom o~ the cap 72. It has a plurality of protuberances ~4 that ~`its into the interior o~ the posts .
, , 2 ~
10 and are sized an~ po~itioned to engage the wall of the post and hold firmly the cap 72 on it. Glue can be used if de~ired, to prevent unauthorized removal of the caps 720 The cap 7~ may al80 be made with downwardly extending stems (not shown) long enough to reach the top edge of the wire mesh 40 and lock it firmly in the small channel 16.
If a post 10 or a wire mesh 40 neede to be replased and this post or wire mesh is not located at an ~extremity of the 10 fence, a replacement post 80 may be used, as shown in Figure 5. The post ~0 comprises a lateral ~lange 82 integrally projecting from one side of a ~lat ridge ~8, and similar to the ~langes 12 of the post 10. It al~o has another L shaped lateral flange 84 detachably fixabla to the other side of 15 flat ridge 88 of the post 80. The flanges ~2 and 84 have open slots ~9 identical to the open slots 30. The flange 84 can be fixed to the post B0 by means of a plurality of bolts insertable into holes ~ made ln its portion faaing thç post $0. The flat ridge 8~ of the post 80 has similar holes (not 20 shown) which are aliyned with the holes 86 ko allow insertion of the bolts used to attaah them together. Rather than being bolted, the flange 84 may be welded to tha post 8~.
The post 10 to be replaced between two or more wire meshes 40, is first cut out near the ground and the wire meshes 40 are removed from its folded free ends 14 of the cut post. The lower portion of the post and its aoncrete ba~e are then removed from the ~round, thereby leaving a new 30 hole ready to be ~illed with concrate. The replacement post ao is th~n in6erted into the new hole and the open slot~ 89 of the flange 82 o~ th~ post 80 is engag~d in the external wire 44 of one o~ the wire meshes 40. The other wire mesh 40 is then engaged in the open slots 89 of the detachable flange 84 which is then ~ttached to the post 80. Last of all, concrete is poured into the new hole to rigidly set the post 80. If the post ~0 is connectad to ~ore than two wire meshes ~0, more than one detachable flange ~4 can be used.
The same method can be used when a wire mesh 40 needs to be replaced except that the post 10 will have to be cut and replaced by a replacement post 80 even if the po6t 10 is not damaged. Locklng keys 60 may be used during these stops to look the wire mesh~s 40 firmly in th~ channel 16.
When a door is needed in the fence, a gate 90 can be made with one of the wire meshes 40 as i~ shown in Figure 6. For that purpose, only one of the lateral side~ 42 of the wi:re mesh 40 designated as "gate" 90, is engaged in the open ~lots 30 of the post 10. Two or more hinging keys 92 ~ade~of rigid plastic material are then meunted on the po~t ~o to keep the external wire o:E the gate 90 locked in the bottom of the channel 16 while allowing rotation of the gate 90.
Pre~erably, on~ of the two keys 92 is install~d clo~e to the top o~ the gate 90 and the other one close ~o the bo~tom o~
the gate~
Figure 10 shows a hinglng key 92. This key 92 is generally U-shaped and sized to fit into the recesses made in the post, whose bottoms are ~e~ined by the flat ridge 20.
At one end, the key 92 comprises an open hole 94 sized to snap onto the wire 4~. ~t the other end, the key 92 comprises a pin ~3 tha~ can be press-~itte~ into a hole 94 made in the body of the post to lock the key 9~ to the po~t 10, as can be seen in Figure 7. The po~t on the other side of the gate 90 can be a replacement post 80 without d~tachable flange 84. A lock (not shown) can then be ;: :

Glue can be used if de~ired, to prevent unauthorized removal of the caps 720 The cap 7~ may al80 be made with downwardly extending stems (not shown) long enough to reach the top edge of the wire mesh 40 and lock it firmly in the small channel 16.
If a post 10 or a wire mesh 40 neede to be replased and this post or wire mesh is not located at an ~extremity of the 10 fence, a replacement post 80 may be used, as shown in Figure 5. The post ~0 comprises a lateral ~lange 82 integrally projecting from one side of a ~lat ridge ~8, and similar to the ~langes 12 of the post 10. It al~o has another L shaped lateral flange 84 detachably fixabla to the other side of 15 flat ridge 88 of the post 80. The flanges ~2 and 84 have open slots ~9 identical to the open slots 30. The flange 84 can be fixed to the post B0 by means of a plurality of bolts insertable into holes ~ made ln its portion faaing thç post $0. The flat ridge 8~ of the post 80 has similar holes (not 20 shown) which are aliyned with the holes 86 ko allow insertion of the bolts used to attaah them together. Rather than being bolted, the flange 84 may be welded to tha post 8~.
The post 10 to be replaced between two or more wire meshes 40, is first cut out near the ground and the wire meshes 40 are removed from its folded free ends 14 of the cut post. The lower portion of the post and its aoncrete ba~e are then removed from the ~round, thereby leaving a new 30 hole ready to be ~illed with concrate. The replacement post ao is th~n in6erted into the new hole and the open slot~ 89 of the flange 82 o~ th~ post 80 is engag~d in the external wire 44 of one o~ the wire meshes 40. The other wire mesh 40 is then engaged in the open slots 89 of the detachable flange 84 which is then ~ttached to the post 80. Last of all, concrete is poured into the new hole to rigidly set the post 80. If the post ~0 is connectad to ~ore than two wire meshes ~0, more than one detachable flange ~4 can be used.
The same method can be used when a wire mesh 40 needs to be replaced except that the post 10 will have to be cut and replaced by a replacement post 80 even if the po6t 10 is not damaged. Locklng keys 60 may be used during these stops to look the wire mesh~s 40 firmly in th~ channel 16.
When a door is needed in the fence, a gate 90 can be made with one of the wire meshes 40 as i~ shown in Figure 6. For that purpose, only one of the lateral side~ 42 of the wi:re mesh 40 designated as "gate" 90, is engaged in the open ~lots 30 of the post 10. Two or more hinging keys 92 ~ade~of rigid plastic material are then meunted on the po~t ~o to keep the external wire o:E the gate 90 locked in the bottom of the channel 16 while allowing rotation of the gate 90.
Pre~erably, on~ of the two keys 92 is install~d clo~e to the top o~ the gate 90 and the other one close ~o the bo~tom o~
the gate~
Figure 10 shows a hinglng key 92. This key 92 is generally U-shaped and sized to fit into the recesses made in the post, whose bottoms are ~e~ined by the flat ridge 20.
At one end, the key 92 comprises an open hole 94 sized to snap onto the wire 4~. ~t the other end, the key 92 comprises a pin ~3 tha~ can be press-~itte~ into a hole 94 made in the body of the post to lock the key 9~ to the po~t 10, as can be seen in Figure 7. The po~t on the other side of the gate 90 can be a replacement post 80 without d~tachable flange 84. A lock (not shown) can then be ;: :
