Definitions

• Barred fencing assembly system comprising a pair of complementary connecting pieces
• the invention relates to the field of fences, and more precisely to fences bars.
• Barred fences have been known for a long time; they can be found on many public or private sites requiring effective protection against intrusions.
• a barred fence conventionally comprises a plurality of cylindrical bars (any section, including circular, rectangular, square, rhombus) maintained spaced by means of a continuous upper smooth and, if necessary, a low even continuous bar.
• a first technique is to drill into the (or) smooth (s) holes of complementary shape of the bars and to press them into the holes, then weld the bars smooth at their interface. This technique is used to make fences with bars over the (s) smooth (s). This first technique is tedious.
• a third technique is to screw the bars on the (the) smooth. This technique is also tedious and requires, in addition, important hardware (screws, nuts, washers) subject to corrosion and thermal fatigue.
• a rod assembly system to form a barred fence, which comprises a first and a second complementary connecting pieces, each connecting piece comprising a body provided with two hollow reserves each complementary to a bar and a pin which protrudes from a bottom of at least one of the reserves to be inserted into a preformed hole in the bar or to perforate it, the first connecting piece being provided with at least one finger which protrudes from the body and the second connecting piece being provided with at least one chimney provided with a bore for receiving in force the finger of the first connecting piece.
• a barred fence comprising a plurality of spaced bars, and a plurality of assembly systems of this type, connecting the bars two by two.
• This system allows rapid assembly of the fence by simply fitting the connecting pieces into each other. It quickly results in a solid fence and beautiful presentation.
• each connecting piece may have a bottom wall and define, opposite this bottom wall, a joint plane
• the pin can extend projecting from the bottom of the reserve without going beyond the joint plane
• the finger can extend from the bottom wall to beyond the joint plane
• the chimney extends for example from the bottom wall to beyond the joint plane
• each connecting piece may comprise a finger and a chimney;
• the finger has for example a square base and a circular top whose diameter is less than or equal to the side of the base; in this case, the bore of the chimney is preferably of a diameter less than or equal to the side of the base of the finger.
• FIG. 1 is an exploded perspective view showing an assembly system of a barred fence by means of a pair of connecting pieces;
• FIG. 2 is a perspective view on a larger scale showing a connecting piece
• FIG. 3 is a sectional view illustrating the assembly of two bars by means of a pair of connecting pieces
• FIG.4 is a sectional view illustrating two bars assembled by means of the two connecting pieces
• FIG. 5 is a perspective view of a fence including a series of bars assembled in pairs by means of a pair of connecting pieces;
• FIG.6 is a perspective view illustrating the splicing of two fence panels on site
• FIG.7 is a sectional view illustrating, on a larger scale, the structure of the splint.
• FIG. 1 shows a system 1 for assembling bars 2 to form a barred fence 3, itself illustrated in FIG.
• This system 1 comprises, to assemble the bars 2 two by two, at least one pair of connecting pieces 4 of complementary shapes, which together jointly trap two bars 2 previously arranged parallel.
• Each connecting piece 4 is advantageously made integrally, e.g. by molding. It is preferable to make each connecting piece 4 in a metallic material, e.g. in an aluminum possibly alloyed. It can provide a treatment such as anodizing for decorative purposes and / or corrosion resistance.
• Each connecting piece 4 comprises a body 5 provided with two reserves 6 recessed each complementary to a bar 2, and at least a pin 7 which protrudes from a bottom of at least one reserve 6 to be inserted into a preformed hole 8 in a bar 2.
• no hole is preformed in the bar 2 and the pin 7 is in this case for perforating the bar 2 during assembly. It is also conceivable to make a pilot hole in the form of a cutout delimiting the edge of the hole 8 without making the piercing, leaving for example a pellet which fills the hole until it is driven by the peg 7 during the assembly.
• the peg 7 is advantageously tapered, and has a base (eg square) wider than its top, so as to be forced into the hole 8 or facilitate the perforation of the bar 2.
• Each pair of connecting pieces 4 comprises:
• the hollow reserves 6 are semicircular contour.
• the connecting pieces 4 are different: the first connecting piece 4, of the male type, comprises one or more fingers 9, and the second connecting piece 4, of female type, comprises one or more chimneys 10 each clean to accommodate a finger 9 of the male link part 4.
• connecting part 4 including both a finger 9 and a chimney 10.
• the two parts 4 of the same connection pair are identical although mounted head to tail, the finger 9 of the first connecting part 4 coming into the chimney 10 of the second connecting part 4, and inversely the finger 9 of the second connecting part 4 coming simultaneously s insert in the chimney 10 of the first connecting part 4.
• each connecting piece 4 is hollow; it has a bottom wall 12 and defines, opposite this bottom wall 12, a plane 13 of joint.
• the connecting pieces 4 are assembled on either side of a pair of bars 2, the planes 13 of joints are applied against each other.
• each connecting piece 4 comprises two pins 7: one in each hollow reserve.
• the (or each) pin 7 protrudes from the bottom of the reserve 6 without going beyond the joint plane 13, to prevent the pins 7 of the connecting pieces 4 of the same pair do abut against each other inside a bar 2.
• the finger 9 and / or the chimney 10 extends (ent) advantageously from the bottom wall 12 to beyond the joint plane 13.
• both the finger 9 and the chimney 10 extend from the bottom wall 12 to beyond the joint plane 13. This maximizes the contact surfaces of the finger 9 and the corresponding chimney 10 and thus ensure good mechanical strength of the connecting pieces 4 forcibly assembled.
• the bore 11 of the stack 10 is preferably of a diameter less than or equal to the side of the base 16 of the finger 9, so that the assembly of the connecting pieces 4 of the same pair causes a fitting by force of the (or each) finger 9 in the corresponding chimney 10 and induces deformation by spacing the chimney 10, the connecting pieces 4 thus being rigidly fixed to one another by the friction of the outer face of the (Of each) finger 9 against the bore 11 deformed of the (or each) corresponding chimney 10, cf.
• a fencing panel 19 is thus obtained comprising a plurality of spaced bars 2, equipped with a plurality of assembly systems 1 connecting the bars 2 in pairs, as illustrated in FIG. We see that this procedure is at least partially automatable.
• This assembly system 1 makes possible many configurations.
• the pins 7 are perforating and the bars 2 devoid of pre-drilled holes, so as to give the editor the freedom to form the fence 3 according to his desire or according to the needs of the land to be fenced.
• the seamless assembly system 1 makes it possible to use bars of various colors to form a colored fence 3 or colored fence panels 19.
• the bars are advantageously colored (eg by spraying) during manufacture, that is to say even before the formation of the fence 3.
• FIG. 6 and FIG. 7 illustrate a method of assembling fencing panels 19 by means of a splinting system, which comprises a pair of similar splints 21 each having a body 22 provided with two reserves. 23 recessed each complementary to a bar 2, and at least one barrel 24 projecting in its center.
• each splint 21 is hollow; it has a bottom wall 25 and defines, opposite this bottom wall 25, a plane 26 of joint.
• the fishplates 21 are assembled on either side of a pair of bars 2, the planes 26 of joints are applied against each other.
• each splint 21 comprises two parallel walls 27 which extend at right angles from the bottom wall 25 to the front edges 28 which together form the plane. 26 of joint.
• the barrel 24 is hollow and opens out on an external face of the splint, to allow the splices to be assembled on either side of a pair of bars 2 (one belonging to a first panel 19 and the other to a second panel 19) adjacent, by means of:
• a screw 29 having a head 30 housed in the barrel 24 of one of the fishplates 21 and a threaded body 31 which extends through a hole 32 pierced at the bottom of the drum 24,
• the hole 32 in the barrel 24 is advantageously square outline, and the screw is provided with a section 37 intermediate complementary square profile, which is housed in the hole 32 without the possibility of rotation.
• the length of the connecting pieces 4 (and if necessary of the fishplates 21) can be adapted according to the demand; in particular, the connecting pieces 4 (and if necessary the fishplates 21) could extend a small length in front of the height of the bars 2 (as in the example illustrated), or on any length up to an equivalent length at the height of the bars 2.
