Description

La présente invention a pour objet un élément de support pour au moins un pied d'une clôture ou d'un panneau de sécurité, cet élément comprenant au moins (a) un moyen d'appui présentant une première face adaptée pour prendre appui sur un sol ou une surface, et une deuxième face opposée à ladite première face adaptée pour venir en contact avec un moyen de lestage, et (b) un moyen adapté pour coopérer avec le pied d'une clôture ou panneau de sécurité.The present invention relates to a support element for at least one foot of a fence or a security panel, this element comprising at least (a) a support means having a first face adapted to bear on a floor or a surface, and a second face opposite said first face adapted to come into contact with a ballast means, and (b) a means adapted to cooperate with the foot of a fence or security panel.

Pour les chantiers, il est requis de pouvoir les sécuriser pour empêcher des accidents pour des piétons ou autres usagers. Pour la protection de tels chantiers, il est connu d'utiliser des clôtures ou panneaux de sécurité, sous forme de grilles s'étendant dans un cadre dont les montants verticaux présentent deux prolongations formant les pieds du panneau ou élément de clôture. Ces pieds sont alors placés dans des éléments supports pour assurer que les panneaux ou clôtures soient sensiblement verticaux. Ces éléments supports sont mobiles pour faciliter le placement des panneaux de sécurité.For construction sites, it is required to be able to secure them to prevent accidents for pedestrians or other users. For the protection of such sites, it is known to use fences or security panels, in the form of grids extending in a frame whose vertical uprights have two extensions forming the feet of the panel or fence element. These feet are then placed in support elements to ensure that the panels or fences are substantially vertical. These support elements are movable to facilitate the placement of the security panels.

On connaît de nombreux éléments de support pour panneaux de sécurité ou clôtures.Many support elements for security panels or fences are known.

On connaît ainsi des plots ou socles en béton présentant une série d'ouvertures adaptées pour recevoir des pieds de panneaux adjacents. De tels plots ou socles présentent l'inconvénient qu'une partie dues plots ou socles s'étend hors du chantier, et donc du côté piétons. Ceci est la cause de nombreux accidents, en particulier pour les personnes ayant des problèmes de vision. De tels plots ou socles sont décrits par exemple dans les documents WO2009/066065 , EP1148186 , GB2255998 , JP20070289567 , etc.Concrete blocks or pedestals having a series of openings adapted to receive legs of adjacent panels are thus known. Such studs or pedestals have the disadvantage that a part of pads or pedestals extends off the site, and therefore the pedestrian side. This is the cause of many accidents, especially for people with vision problems. Such studs or pedestals are described for example in the documents WO2009 / 066065 , EP1148186 , GB2255998 , JP20070289567 etc.

On connaît par le document FR2899911 un élément de support (1) pour au moins un pied d'une clôture ou d'un panneau de sécurité, cet élément comprenant au moins (a) un moyen d'appui (10) présentant une première face adaptée pour prendre appui sur un sol ou une surface, et une deuxième face opposée à ladite première face adaptée pour venir en contact avec un moyen de lestage (L) ou apte à coopérer avec un ou des moyens de fixation, et (b) un moyen (11) adapté pour coopérer avec le pied (P) d'une clôture ou panneau de sécurité (C), dans lequel ledit moyen (11) adapté pour coopérer avec ledit pied (P) comprend (a) une partie (R) définissant une gorge (G) sensiblement en U avec un axe longitudinal (A.), ladite gorge (G) ayant un fond (F) présentant ou associé à un élément ou face (FI) adapté pour prendre appui sur ledit sol ou surface, et (b) une pièce (12) attachée à ladite partie (R), éloignée du fond (F) de la gorge (G) et s'étendant au-dessus de ladite gorge (G) lorsque l'élément ou face (FI) prend appui sur une surface sensiblement horizontale, ladite pièce (12) présentant au moins une ouverture (12A,12B) située au-dessus dudit fond (F) de ladite gorge (G), ladite au moins une ouverture (12A,12B) étant adaptée pour permettre le passage d'une partie du pied (P) d'une clôture ou panneau, tandis que ladite gorge (G) est adaptée pour recevoir l'extrémité (PE) dudit pied (P) passant au travers de ladite au moins une ouverture (12A,12B), ladite au moins une ouverture (12A, 12B) et la dite gorge (G) présentant chacun une forme adaptée pour limiter au moins un mouvement de pivotement du pied (P) par rapport à l'axe longitudinal (A) de la gorge (G), et pour lequel il est réalisé au moins partiellement au moyen d'une tôle en métal, avantageusement en acier, pliée de manière à former la gorge (G) et la pièce (12) présentant ladite au moins une ouverture (12A,12B) située au dessus de la gorge (G).We know from the document FR2899911 a support element (1) for at least one foot of a fence or safety panel, this element comprising at least (a) a support means (10) having a first face adapted to bear on a floor or a surface, and a second face opposite to said first face adapted to come into contact with a ballast means (L) or adapted to cooperate with one or more fastening means, and (b) means (11) adapted to cooperate with the foot (P) of a fence or security panel (C), wherein said means (11) adapted to cooperate with said foot (P) comprises (a) a portion (R) defining a groove (G) substantially U-shaped with a longitudinal axis (A.), said groove (G) having a bottom (F) having or associated with an element or face (FI) adapted to bear on said ground or surface, and (b) a part (12) attached to said portion (R) away from the bottom (F) of the groove (G) and extending above said groove (G) when the element or ace (FI) bears on a substantially horizontal surface, said part (12) having at least one opening (12A, 12B) located above said bottom (F) of said groove (G), said at least one opening (12A , 12B) being adapted to allow the passage of a portion of the foot (P) of a fence or panel, while said groove (G) is adapted to receive the end (PE) of said foot (P) passing through of said at least one opening (12A, 12B), said at least one opening (12A, 12B) and said groove (G) each having a shape adapted to limit at least one pivoting movement of the foot (P) relative to the longitudinal axis (A) of the groove (G), and for which it is made at least partially by means of a metal sheet, advantageously made of steel, folded so as to form the groove (G) and the piece ( 12) having said at least one opening (12A, 12B) located above the groove (G).

On connaît également des platines de support pour un pied d'un premier panneau et un pied d'un deuxième panneau adjacent du premier. Ces platines présentent un moyen pour coopérer avec un moyen de lestage, par exemple un socle en béton. On connaît ainsi une platine constitué d'un plat de section carrée sur lequel sont soudés deux tubes destinés chacun à recevoir un pied d'un panneau. Le plat de section carré est destiné à être appliqué sur le sol et une dalle en béton peut être placée sur ledit plat. On connaît encore un plat allongé à une extrémité duquel sont soudés deux tubes pour recevoir un pied de deux panneaux adjacents, et à l'autre extrémité duquel est soudé un tube destiné à être inséré dans le creux d'un moyen de lestage ou d'un socle.
Ces platines sont difficiles à fabriquer. De plus, les tubes peuvent facilement s'encrasser, de sorte que l'enfoncement d'un pied dans un tube peut ne pas être suffisant et peut donc constituer un risque d'accident. Le nettoyage de telles platines est difficile, voir impossible, si du béton ou de l'argile ont durci dans un tube.Support plates are also known for a foot of a first panel and a foot of a second panel adjacent to the first panel. These plates have a means for cooperating with a weighting means, for example a concrete base. There is thus known a plate consisting of a flat square section on which are welded two tubes each for receiving a foot of a panel. The dish of square section is intended to be applied on the ground and a concrete slab can be placed on said dish. There is also known an elongated plate at one end of which are welded two tubes for receiving a foot of two adjacent panels, and at the other end of which is welded a tube intended to be inserted in the hollow of a weighting means or a pedestal.
These plates are difficult to manufacture. In addition, the tubes can easily become dirty, so that the depression of a foot in a tube may not be sufficient and may therefore be a risk of accident. Cleaning such platens is difficult, if not impossible, if concrete or clay has hardened in a tube.

Cet élément support 1 est réalisé au moins partiellement au moyen d'une tôle en métal, avantageusement en acier, (par exemple présentant une épaisseur de 3 à 10mm) pliée de manière à former le rail (R) et la pièce (12) présentant l'ouverture (12A,12B) située au dessus de la gorge (G) définie par ledit rail (R). Après pliage, l'élément peut subir un ou plusieurs traitements, tels que durcissement, peinture, etc. Les trous ou orifices de l'élément sont avantageusement réalisés avant pliage.This support member 1 is made at least partially by means of a metal sheet, advantageously made of steel, (for example having a thickness of 3 to 10 mm) folded so as to form the rail (R) and the piece (12) having the opening (12A, 12B) located above the groove (G) defined by said rail (R). After folding, the element can undergo one or more treatments, such as curing, painting, etc. The holes or orifices of the element are advantageously made before folding.

La tôle pliée présente une partie formant le moyen d'appui (10) adaptée pour venir en contact avec un moyen de lestage (L). Dans une forme de réalisation possible, cette partie 10 aurait pu être solidaire d'un socle, par exemple en béton.The folded sheet has a portion forming the support means (10) adapted to come into contact with a ballasting means (L). In a possible embodiment, this portion 10 could have been secured to a base, for example concrete.

La partie formant le moyen d'appui (10) de la tôle pliée adaptée pour venir en contact avec le moyen de lestage (L) présente une face inférieure (FI) adaptée pour prendre appui sur le sol ou surface, la partie formant le moyen d'appui (10) de la tôle pliée adaptée pour venir en contact avec le moyen de lestage (L) présentant avantageusement une protubérance (10A) adaptée pour être insérée dans un creux du moyen de lestage (L). La protubérance 10A peut avoir la forme d'un plat qui peut servir de butée à un socle déposé sur la partie formant le moyen d'appui 10.The portion forming the support means (10) of the folded sheet adapted to come into contact with the weighting means (L) has a bottom face (FI) adapted to bear on the ground or surface, the portion forming the means bearing (10) of the folded sheet adapted to come into contact with the weighting means (L) advantageously having a protuberance (10A) adapted to be inserted into a recess of the ballast means (L). The protuberance 10A may be in the form of a plate that can serve as a stop for a base deposited on the part forming the support means 10.

La partie de rail (R) définissant une gorge (G) sensiblement en U présente un fond (F) avec une face inférieure (FI) s'étendant dans un plan (H), tandis que la partie (10) de la tôle pliée adaptée à venir en contact avec un moyen de lestage (L) présente une face inférieure (101) s'étendant sensiblement dans le plan (H) de la face inférieure (FI) du fond (F) de la gorge (G) du rail (R).The rail portion (R) defining a substantially U-shaped groove (G) has a bottom (F) with a bottom face (FI) extending in a plane (H), while the portion (10) of the folded sheet adapted to come into contact with a weighting means (L) has a lower face (101) extending substantially in the plane (H) of the lower face (FI) of the bottom (F) of the groove (G) of the rail (R).

La partie (10) de la tôle pliée adaptée pour venir en contact avec un moyen de lestage (L) présente au moins un trou (10X).The portion (10) of the folded sheet adapted to come into contact with a ballasting means (L) has at least one hole (10X).

La pièce (12) attachée audit rail (R), éloignée du fond (F) de la gorge (G) dudit rail (R) et s'étendant au-dessus de ladite gorge (G) lorsque l'élément (1) prend appui sur une surface sensiblement horizontale, présente au moins deux ouvertures (12A,12B) adaptées chacune pour permettre le passage d'une partie du pied (P) d'une clôture ou panneau.The piece (12) attached to said rail (R), remote from the bottom (F) of the groove (G) of said rail (R) and extending above said groove (G) when the member (1) takes support on a substantially horizontal surface, has at least two openings (12A, 12B) each adapted to allow the passage of a portion of the foot (P) of a fence or panel.

L'élément comprend avantageusement au moins un moyen pour l'associer à un profilé longitudinal ou planche ou à un moyen de guidage (100). Un tel moyen est représenté à la figure 4. Ce moyen est réalisé en pliant un morceau de tôle (par exemple en acier) de manière à définir un élément 50 en U associé à un plat 51 avec une ouverture 52. Le plat 51 est adapté pour être placé sur la pièce 12 du support 1, avant d'introduire le pied d'un panneau C. Le crochet en U 50 s'étend ainsi devant l'aile R2 du rail R. Une planche peut alors prendre appui dans le crochet 50, de manière que cette planche s'étende dans le bas du panneau C et puisse servir de moyen de guidage pour la canne d'un non voyant. Le moyen de la figure 4 est intéressant, car il est possible de modifier la position du crochet 50 en faisant pivoter le plat 51 par rapport à la pièce 12, Le crochet 50 peut ainsi pivoter entre une position où il se trouve devant l'aile R2 et une position où il se trouve dans le prolongement du rail ou dans l'axe du rail. Le crochet 50 présente par exemple une aile éloignée du plat 51 avec une ou des ouvertures destinées à livrer passage à une attache, vis, etc. pour maintenir en position un profilé ou planche prenant appui dans ce crochet 50.The element advantageously comprises at least one means for associating it with a longitudinal profile or board or a guide means (100). Such a means is represented in figure 4 . This means is achieved by folding a piece of sheet metal (for example steel) so as to define a U-shaped element 50 associated with a plate 51 with an opening 52. The plate 51 is adapted to be placed on the part 12 of the support 1 , before introducing the foot of a panel C. The U-shaped hook 50 thus extends in front of the flange R2 of the rail R. A board can then bear in the hook 50, so that this board extends in the bottom of the panel C and can serve as guide means for the rod of a blind. The means of figure 4 is interesting because it is possible to change the position of the hook 50 by pivoting the plate 51 relative to the part 12, the hook 50 can rotate between a position where it is in front of the wing R2 and a position where it is in the extension of the rail or in the axis of the rail. The hook 50 has for example a wing remote from the plate 51 with one or more openings intended to allow passage to a fastener, screw, etc. to maintain in position a profile or board bearing in this hook 50.

La face inférieure et la face supérieure du profilé présentent des ouvertures 12A, 12B, de manière à pouvoir utiliser l'élément sur ses deux faces opposées.The figure 10 shows an embodiment attached to the weighting means L. The sheet is folded to form a hollow profile extended by two plates 10 ending in abutments 10A. The plates 10 and their stops are intended to extend in the weighting means L, for example of the concrete type or other. The lower face and the upper face of the profile have openings 12A, 12B, so that the element can be used on its two opposite faces.

La figure 11 montre l'élément de la figure 1 associé à un moyen d'attache 50 similaire à celui de la figure 4. Ce moyen d'attache est réalisé à partir d'une tôle pliée et présente un plat 51 avec une ouverture 52 adapté pour prendre appui sur la pièce 12. Le plat 51 est prolongé par une section pliée pour former une sorte de profilé empêchant des mouvements vers le bas, vers le haut et latéraux d'une planche 100 introduite dans le profilé. Le pied d'une clôture introduit dans l'ouverture 52 et dans une ouverture 12A,12B permet de maintenir le moyen d'attache sur l'élément 1.The figure 11 shows the element of the figure 1 associated with a fastening means 50 similar to that of the figure 4 . This attachment means is made from a folded sheet and has a plate 51 with an opening 52 adapted to bear on the piece 12. The plate 51 is extended by a folded section to form a kind of profile preventing movements downwards, upwards and sideways of a board 100 introduced into the profile. The foot of a fence introduced into the opening 52 and into an opening 12A, 12B makes it possible to hold the attachment means on the element 1.

La figure 13 est une vue d'une forme de réalisation similaire à celle de la figure 1, si ce n'est que l'aile R2 présente deux fentes 60. Les crochets 50 sont constitués par une patte pliée en U, avec une âme 55 destinée à servir de point d'appui à une planche 100, une aile courte 56 adaptée pour passer par la fente 60, et une aile longue 57 pour servir d'appui latéral la planche. La fente 60 est situé à une distance de la pièce 12 sensiblement égale ou inférieure à la largeur de l'âme, cette distance étant inférieure à la hauteur de l'aile courte 56. Le placement du crochet 50 s'opère alors en plaçant l'aile longue sur la pièce 12 pour insérer l'aile courte 56 à travers la fente 60. Ensuite on fait pivoter l'aile longue 57 pour amener l'aile courte 56 contre la face interne de l'aile R2 de la gorge G du rail R.The figure 13 is a view of an embodiment similar to that of the figure 1 , except that the wing R2 has two slots 60. The hooks 50 are constituted by a U-folded leg, with a core 55 intended to serve as a fulcrum for a board 100, a short wing 56 adapted to pass through the slot 60, and a long wing 57 to serve as lateral support the board. The slot 60 is located at a distance from the part 12 substantially equal to or less than the width of the core, this distance being less than the height of the short wing 56. The placement of the hook 50 is then effected by placing the long wing on the piece 12 to insert the short wing 56 through the slot 60. Then the long wing 57 is pivoted to bring the short wing 56 against the inner face of the wing R2 of the groove G of the rail R.

Les supports selon l'invention peuvent être réalisés par pliage d'une tôle prédécoupée. Ce procédé comporte ainsi alors les étapes suivantes :

  • on découpe dans une tôle une section de tôle à plier, par exemple pour avoir une forme générale comprenant une première partie rectangulaire (pour le rail, la pièce 12 et la partie 15), une partie trapézoïdale (pour la partie 10) et une partie rectangulaire (pour la butée 10A) ;
  • on forme dans ladite section de tôle une ou des ouvertures (12A,12B, 10X);
  • on coupe éventuellement la section de tôle à plier pour former une ou des pattes à plier (pour former les crochets 30);
  • on plie la section de tôle à plier pour former au moins le rail définissant la gorge en forme de U et la pièce avec la ou les ouvertures pour le pied d'une clôture ou panneau.
The supports according to the invention can be made by folding a pre-cut sheet. This process thus comprises the following steps:
  • a section of sheet metal to be bent is cut from a sheet, for example to have a general shape comprising a first rectangular part (for the rail, the piece 12 and part 15), a trapezoidal part (for part 10) and a rectangular part (for abutment 10A);
  • forming in said sheet metal section one or more openings (12A, 12B, 10X);
  • the section of sheet metal to be folded is optionally cut to form one or more tabs to be folded (to form the hooks 30);
  • the sheet metal section is folded to form at least the rail defining the U-shaped groove and the piece with the aperture (s) for the foot of a fence or panel.

Après le pliage de la tôle découpée, on peut traiter l'élément 1 pour accroître sa dureté, sa résistance la corrosion, etc., par exemple en le peignant.After folding the cut sheet, the element 1 can be treated to increase its hardness, corrosion resistance, etc., for example by painting it.

Une fois pliée et traitée (par exemple galvanisée), la tôle peut être associée à un moyen de lestage, par exemple en noyant une partie de la tôle dans un béton ou dans un bloc de résine ou de polymère chargé, par exemple de matière minérale ou autres chargesOnce folded and treated (for example galvanized), the sheet may be associated with a weighting means, for example by embedding part of the sheet in a concrete or in a block of resin or charged polymer, for example of mineral material or other charges
