Dans le domaine des barrieres de protection visant a delimiter un espace protege, tel que le terrain entourant une maison d' habitation ou un local industrial, il est connu de realiser une barriere a base de poteaux et d'un grillage tendu entre ces poteaux. Une telle solution est peu esthetique et relativement onereuse, alors qu'elle resiste mal aux efforts transversaux et que sa duree dans le temps est relativement faible. I1 est egalement connu de realiser une barriere en fer forge en constituent des elements rigides destines a etre implantes sur un soubassement ou un mur en beton. Une telle solution est onereuse et n'est pas a la portee d'un bricoleur occasionnel. Des problemes analogues se posent en ce qui concerne les barrieres destinees a entourer un lieu potentiellement dangereux, tel qutune piscine. Dans ce second cas, le caractere inesthetique d'une solution avec grillage est In the field of protective barriers intended to delimit a protected space, such as the land surrounding a dwelling house or an industrial premises, it is known to make a barrier based on poles and a fence stretched between these poles. Such a solution is unattractive and relatively expensive, while it resists transverse forces poorly and its duration over time is relatively short. It is also known to make a wrought iron barrier made of rigid elements intended to be installed on a base or a concrete wall. Such a solution is expensive and is not within the reach of an occasional handyman. Similar problems arise with regard to barriers intended to surround a potentially dangerous place, such as a swimming pool. In this second case, the unsightly character of a solution with grating is

souvent considere comme redhibitoire. often seen as unacceptable.

element de barriere et d'une barriere conformes a son principe, donnee uniquement a titre d'exemple et faite en reference aux dessins annexes dans lesquels: - la figure 1 est une representation schematique en perspective d'une barriere conforme a l' invention incorporant des elements de barriere conformes a l' invention; - la figure 2 est une vue a plus grande echelle du detail II a la figure 1; - la figure 3 est une vue, a plus grande echelle et avec arrachement partiel, du detail III a la figure 1; - la figure 4 est une vue eclatee du detail de la figure 2; - la figure 5 est une representation schematique, eclatee et en cours de montage, d'un element de la barriere de la figure 1 et - la figure 6 est une vue analogue a la figure 4 pour un element de barriere conforme a un second mode de barrier element and a barrier in accordance with its principle, given solely by way of example and made with reference to the accompanying drawings in which: - Figure 1 is a schematic perspective representation of a barrier according to the invention incorporating barrier elements according to the invention; - Figure 2 is a view on a larger scale of detail II in Figure 1; - Figure 3 is a view, on a larger scale and with partial cutaway, of detail III in Figure 1; - Figure 4 is an exploded view of the detail of Figure 2; - Figure 5 is a schematic representation, exploded and during assembly, of an element of the barrier of Figure 1 and - Figure 6 is a view similar to Figure 4 for a barrier element according to a second mode of

realisation de ['invention.realization of the invention.

La barriere B representee partiellement a la figure 1 comporte plusieurs elements fixes, dont un seul est represente avec la reference E, ainsi qu'un portillon P The barrier B partially shown in Figure 1 has several fixed elements, only one of which is represented with the reference E, as well as a gate P

articule autour d'un axe Z-Z' globalement vertical. hinges around a generally vertical axis Z-Z '.

Des elements E supplementaires prolongent les elements representes a la figure 1 dans le sens des lignes pointillees. L'element E comprend deux poteaux 1 et 2 realises par pliage de t81e et disposes avec leurs axes longitudinaux respectifs Zl-Z'l, Z2-Z'2 globalement verticaux. Chaque poteau 1 ou 2 est pourvu d'une platine 11, respectivement 21, permettant sa fixation sur un sol globalement plan Additional E elements extend the elements shown in Figure 1 in the direction of the dotted lines. Element E comprises two posts 1 and 2 made by folding t81e and arranged with their respective longitudinal axes Zl-Z'l, Z2-Z'2 generally vertical. Each post 1 or 2 is provided with a plate 11, respectively 21, allowing its fixing on a generally flat ground

grace a des vis 12, respectivement 22. with screws 12 and 22 respectively.

En variante de l'utilisation des platines 11 et 21, les poteaux 1 et 2 pourraient etre introduits dans des fourreaux scelles dans le sol ou euxmemes directement As a variant of the use of the plates 11 and 21, the posts 1 and 2 could be introduced into sheaths sealed in the ground or themselves directly

scelles dans le sol.seals in the ground.

Une traverse 3 s'etend entre les poteaux 1 et 2 en partie inferieure de ceux-ci et est supportee par des equerres 13 et 23 en t81e pliee qui vent boulonnees respectivement sur les poteaux 1 et 2. La traverse 3 est A cross member 3 extends between the posts 1 and 2 in the lower part of these and is supported by brackets 13 and 23 in folded t81e which wind bolted respectively on the posts 1 and 2. The cross member 3 is

elle-meme boulonnee sur les equerres 13 et 23. itself bolted to brackets 13 and 23.

Cette traverse est formee par pliage de tole, avec une section transversale globalement en forme de U. comme les This crosspiece is formed by bending sheet metal, with a cross section generally in a U shape.

poteaux 1 et 2.posts 1 and 2.

Une seconde traverse 4 est prevue en partie superieure de ['element E et s'etend entre les poteaux 1 et 2 en etant parallele a la traverse 3, cette traverse 4 etant egalement boulonnee sur des equerres 14 et 24, elles memes A second cross member 4 is provided in the upper part of the element E and extends between the posts 1 and 2 being parallel to the cross member 3, this cross member 4 also being bolted on brackets 14 and 24, themselves

respectivement boulonnees sur les poteaux 1 et 2. bolted to posts 1 and 2 respectively.

En pratique, les traverses 3 et 4 vent identiques et s'etendent selon des directions globalement horizontales In practice, the crossbeams 3 and 4 are identical and extend in generally horizontal directions

loreque les poteaux 1 et 2 vent verticaux. loreque poles 1 and 2 vertical vent.

Treize barreaux 5, avec une section transversale en forme de U. vent prevus sur ltelement E et stetendent selon des directions globalement paralleles aux poteaux 1 et 2, chaque barreau 5 s'etendant entre les traverses et depassant, respectivement, en dessous de la traverse 3 et Thirteen bars 5, with a U-shaped cross section. Wind provided on the element E and extend in directions generally parallel to the posts 1 and 2, each bar 5 extending between the crosspieces and exceeding, respectively, below the crosspiece 3 and

au dessus de la traverse 4.above the crossbar 4.

Comme il ressort plus particulierement des figures 2 et 4, chaque barreau 5 est prevu pour etre introduit partiellement dans une ouverture 31 globalement en forme de U qui est menagee dans le voile superieur 32 de la traverse 3. En pratique, les dimensions transversales de l'ouverture 31 vent legerement superieures a ltepaisseur de la feuille de t81e dans laquelle est forme le barreau 5, ce qui permet une introduction aisee de ce barreau dans cette ouverture. En revanche, une fois ce barreau introduit dans cette ouverture, il ne peut pas pivoter autour d'un axe vertical, car ses voiles lateraux 51 et 52 vent respectivement bloques dans les parties laterales 33 et 34 As can be seen more particularly in FIGS. 2 and 4, each bar 5 is designed to be partially introduced into an opening 31 generally in the form of a U which is formed in the upper web 32 of the cross member 3. In practice, the transverse dimensions of the 'opening 31 wind slightly greater than the thickness of the sheet of sheet in which the bar 5 is formed, which allows easy introduction of this bar into this opening. On the other hand, once this bar introduced into this opening, it cannot pivot around a vertical axis, because its lateral sails 51 and 52 are respectively blocked in the lateral parts 33 and 34

de louverture 31.opening 31.

Le voile de fond 53 du poteau 5 est prevu pour etre The bottom cover 53 of the post 5 is provided to be

engage dans une partie de fond 35 de l'ouverture 31. engages in a bottom portion 35 of the opening 31.

Afin de limiter le mouvement diintroduction du barreau dans ltouverture 31 et de maintenir celui-ci a une hauteur pre-determinee par rapport au sol, le voile 53 est pourvu d'un creve 54 faisant saillie vers l'exterieur du barreau 5 par rapport a ce voile. Ainsi, au terme du mouvement diintroduction de l'extremite inferieure 55 du barreau 5 dans l'ouverture 31, mouvement qui est represente par les fleches F1 aux figures 4 et 5, le creve 54 vient en appui contre la face superieure 36 du voile 32, comme lo represente a la figure 2, la traverse 3 exergant alors sur le creve 54 un effort de reaction represente par la fleche In order to limit the movement of introduction of the bar into the opening 31 and to maintain the latter at a predetermined height relative to the ground, the veil 53 is provided with a hole 54 projecting towards the outside of the bar 5 relative to this veil. Thus, at the end of the movement of introduction of the lower end 55 of the bar 5 into the opening 31, a movement which is represented by the arrows F1 in FIGS. 4 and 5, the hole 54 comes to bear against the upper face 36 of the web 32 , as shown in FIG. 2, the cross-member 3 then exerting on the puncture 54 a reaction force represented by the arrow

F2 qui compense le poids du barreau 5. F2 which compensates for the weight of the bar 5.

Comme il ressort plus particulierement de la figure 5, le montage de ltelement E peut avoir lieu sans soudure, des boulons etant utilises uniquement pour solidariser les equerres 13, 14, 23 et 24 respectivement avec les poteaux 1 As can be seen more particularly from FIG. 5, the mounting of the element E can take place without welding, bolts being used only to secure the brackets 13, 14, 23 and 24 respectively with the posts 1

et 2 et avec les traverses 3 et 4.and 2 and with crosspieces 3 and 4.

Lors d'une premiere etape de montage, on fixe les equerres 13, 14, 23 et 24 sur les poteaux 1 et 2. Ensuite' on monte la traverse 3 sur les equerres 13 et 23, ce qui During a first mounting step, the brackets 13, 14, 23 and 24 are fixed on the posts 1 and 2. Then 'the cross member 3 is mounted on the brackets 13 and 23, which

permet d'atteindre la position representee a la figure 5. allows to reach the position represented in figure 5.

Dans cette position, on introduit les extremites inferieures 55 des differents barreaux chacune dans une ouverture 31 de la traverse 3, les ouvertures 31 etant prevues en nombre correspondent au nombre de barreaux 5. Le mouvement diintroduction F1 des extremites 55 dans les ouvertures 31 est poursuivi jusquia ce que les creves 54 des differents barreaux viennent en appui contre la face In this position, the lower ends 55 of the various bars are each introduced into an opening 31 of the cross-member 3, the openings 31 being provided in number correspond to the number of bars 5. The movement diintroduction F1 of the ends 55 in the openings 31 is continued until the holes 54 of the various bars come to bear against the face

superieure 36 de la traverse 3.upper 36 of cross 3.

Dans cette configuration, la traverse 4 est deplacee en direction des equerres 14 et 24, comme represente par la fleche F3, en prenant vein d'introduire les extremites superieures 56 des barreaux 5 dans des ouvertures 41 prevues dans la traverse 4 avec la meme geometric que les ouvertures 31. La traverse 4 est alors boulonnee sur les In this configuration, the cross member 4 is moved in the direction of the brackets 14 and 24, as represented by the arrow F3, taking care to introduce the upper ends 56 of the bars 5 into openings 41 provided in the cross member 4 with the same geometric that the openings 31. The cross 4 is then bolted to the

equerres 14 et 24.brackets 14 and 24.

Afin de garantir qu'un barreau 5 ne peut pas etre souleve de facon trop importante par rapport aux traverses 3 et 4, chaque barreau 5 est pourw d'un second creve 57 faisant saillie par rapport au voile de fond 53 et destine a venir en appui contre la face inferieure 46 d'un voile superieur 42 de la traverse 4. Ceci empeche un mouvement d' extraction du barreau 5 par rapport aux ouvertures 31 et In order to guarantee that a bar 5 cannot be lifted too much in relation to the crosspieces 3 and 4, each bar 5 is provided with a second hole 57 projecting from the bottom wall 53 and intended to come in bearing against the lower face 46 of an upper web 42 of the crosspiece 4. This prevents the bar 5 from being extracted relative to the openings 31 and

41 dans le sens de la fleche F4 a la figure 3. 41 in the direction of the arrow F4 in FIG. 3.

On note cependant qu'il niest pas obligatoire de prevoir un second creve sur les barreaux 5, un meme creve pouvant venir en appui respectivement avec les deux traverses 3 et 4. Cependant, l'utilisation de deux creves 55 et 57 separes d'une distance d5 legerement inferieure a la distance d1 entre les faces superieures des equerres 13 et 14, respectivement 23 et 24, permet d' assurer que ['amplitude des mouvements verticaux des barreaux 5 par It should be noted, however, that it is not compulsory to provide a second hole on the bars 5, the same hole being able to bear respectively with the two crosspieces 3 and 4. However, the use of two holes 55 and 57 separated by a distance d5 slightly less than the distance d1 between the upper faces of the brackets 13 and 14, respectively 23 and 24, ensures that the amplitude of the vertical movements of the bars 5 by

rapport aux traverses 3 et 4 est limitee. compared to sleepers 3 and 4 is limited.

On note que la geometric des creves 54 et 55 est inversee, la partie la plus saillante de chaque creve 54 ou 57 etant orientee vers l'extremite la plus proche 55 ou 56 Note that the geometry of the drifts 54 and 55 is reversed, the most projecting part of each dive 54 or 57 being oriented towards the nearest end 55 or 56

du barreau 5.of the bar 5.

Les barreaux 5 vent symetriques en ce qui concerne le positionnement des creves 54 et 57 par rapport aux extremites 55 et 56, de sorte que l'une ou l'autre de leur extremite peut etre inseree dans les ouvertures 31 ou 41 The bars 5 wind symmetrical with regard to the positioning of the holes 54 and 57 relative to the ends 55 and 56, so that either of their ends can be inserted into the openings 31 or 41

des traverses 3 ou 4 lors du montage. cross members 3 or 4 during assembly.

Le montage de l' clement E est tres aise alors que, une fois monte, cet element est particulierement resistant, The assembly of the element E is very easy whereas, once assembled, this element is particularly resistant,

alors qu'aucune soudure n'a ete necessaire. when no soldering was necessary.

Selon une variante non representee de ['invention, liun ou les deux creves 54 et 57 d'un poteau 5 pourraient etre orientes vers l'interieur du U forme par la section transversale de chaque poteau. Cette variante evite que les creves voisins de la traverse 3 ne soient trop visibles, mais elle induit qu'ils portent sur une languette 37 definie entre les parties 33 et 34 de l'ouverture 31, cette languette pouvant flechir sous l'effet du poids d'un poteau 5. C,est pourquoi, la solution avec les creves faisant saillie vers l'exterieur de chaque poteau est preferee, car la traverse 3 est plus resistante dans la zone d'appui 38 prevue a l' exterieur de l' ouverture 31, au voisinage de la According to a variant not shown of the invention, liun or the two holes 54 and 57 of a post 5 could be oriented towards the inside of the U formed by the cross section of each post. This variant avoids that the holes adjacent to the crosspiece 3 are too visible, but it induces that they bear on a tongue 37 defined between the parts 33 and 34 of the opening 31, this tongue being able to bend under the effect of the weight. of a post 5. This is why, the solution with the holes protruding towards the outside of each post is preferred, because the crosspiece 3 is more resistant in the support zone 38 provided outside of the opening 31, near the

zone de pliage 39 de la traverse 3.folding zone 39 of the cross member 3.

Le portillon P est realise avec la meme technique et comprend deux poteaux 101 et 102 sensiblement verticaux, le poteau 102 etant articule par des charnieres non representees sur un poteau d'ancrage 102'. Des traverses 15 103 et 104 vent montees sur des poteaux 101 et 102 et vent pourvues d'ouvertures d/introduction de barreaux 105 identiques aux barreaux 5 de l' clement E, les traverses 103 et 104 etant generalement plus courses que les traverses 3 et 4. Selon un aspect avantageux de l' invention qui ntest pas represente, les traverses 3 et 4 peuvent etre prevues en differentes longueurs, par exemple de 1 metre, 1,50 metre et 2 metres, ce qui permet d'ajuster la longueur des elements E a la longueur de la barriere B a realiser. En outre, un jeu de traverses d'ajustement peut etre prevu dans lesquelles des percages de passage de boulons de fixation sur les equerres vent menages en plusieurs endroits, chaque traverse pouvant ainsi etre coupee a la longueur choisie, tout en demeurant montable sur les The gate P is made with the same technique and comprises two substantially vertical posts 101 and 102, the post 102 being articulated by hinges not shown on an anchoring post 102 ′. Crosspieces 15 103 and 104 wind mounted on poles 101 and 102 and wind provided with openings for the introduction of bars 105 identical to the bars 5 of the element E, the crossbars 103 and 104 being generally shorter than the crossbeams 3 and 4. According to an advantageous aspect of the invention which is not shown, the sleepers 3 and 4 can be provided in different lengths, for example 1 meter, 1.50 meter and 2 meters, which makes it possible to adjust the length of the elements E to the length of the barrier B to be made. In addition, a set of adjustment crosspieces can be provided in which holes for the passage of fixing bolts on the brackets are provided in several places, each crosspiece can thus be cut to the chosen length, while remaining mountable on the

equerres.equerres.

Des jambes de force peuvent etre montees sur les poteaux 1 et 2 afin de rigidifier ltelement E. De meme, deux poteaux 1 ou 2 de deux elements E voisins peuvent etre assembles ensemble dans le meme but, auquel cas l'un de ces Struts can be mounted on posts 1 and 2 in order to stiffen the element E. Similarly, two posts 1 or 2 of two neighboring elements E can be assembled together for the same purpose, in which case one of these

poteaux est depourvu de platine.posts is devoid of platinum.

Dans le second mode de realisation de ['invention represente a la figure 6, les elements analogues a ceux du premier mode de realisation portent des references identiques augmentees de 200. La traverse 203 de ce mode de realisation est egalement pourvue d'une ouverture 231 en forme de U reproduisant approximativement la section transversale d'un barreau 205. Ce mode de realisation differe du precedent en ce que le relief 254 prevu sur le voile de fond 253 du poteau 205 n'est pas un creve mais une bosse formee par emboutissage localise du voile 253 et destinee a venir en appui contre une zone d'appui 238 de la In the second embodiment of the invention represented in FIG. 6, elements similar to those of the first embodiment bear identical references increased by 200. The cross member 203 of this embodiment is also provided with an opening 231 U-shaped reproducing approximately the cross section of a bar 205. This embodiment differs from the previous one in that the relief 254 provided on the bottom wall 253 of the post 205 is not a crevice but a bump formed by stamping locates the veil 253 and intended to come into abutment against a support zone 238 of the

traverse 203.cross 203.

En fait, plusieurs geometries du relief 254 peuvent etre envisagees dans le cadre de la presente invention, pour aut ant que ce relief forme une butee au mouvement d/introduction de l'extremite inferieure 255 du barreau 205 In fact, several geometries of the relief 254 can be envisaged in the context of the present invention, insofar as this relief forms a stop for the movement of introduction of the lower end 255 of the bar 205

dans l'ouverture 231.in opening 231.

Quel que soit le mode de realisation considere, l' invention presente l'avantage particulier qu'un element de barriere conforme a son principe peut etre transporte demonte jusqu'a son lieu d' installation, les poteaux, les traverses et les barreaux etant alors disposes parallelement les uns aux autres et formant un << fagot >> compact et aise a manipuler. Sur le site d/installation, il suffit a un bricoleur, meme peu experimente, de mettre en uvre le procede mentionne ci-dessus a l' aide d'une simple clef pour boulonner les equerres, afin d'obtenir une Whatever the embodiment considered, the invention has the particular advantage that a barrier element in accordance with its principle can be transported disassembled to its place of installation, the posts, crosspieces and bars being then arranged parallel to each other and forming a compact and easy to handle "bundle". On the installation site, it is enough for a handyman, even an inexperienced one, to implement the process mentioned above using a simple key to bolt the brackets, in order to obtain a
