Description

La présente invention concerne les socles destinés à recevoir des pieds de barrières ou de palissades pour délimiter par exemple des chantiers ou des zones de travaux, tant à l'intérieur qu'à l'extérieur, et leurs accessoires.The present invention relates to pedestals intended to receive feet of barriers or palisades to delimit for example building sites or areas of works, both indoors and outdoors, and their accessories.

Les socles connus, encore parfois appelés plots, comportent des logements disjoints agencés pour recevoir les pieds de deux barrières adjacentes à maintenir.Known bases, also sometimes called studs, have housings disjointed arranged to receive the feet of two adjacent barriers to maintain.

A titre d'exemples de tels socles, on peut se référer par exemple aux publications NL 10 08 592, NL 94 01555, DE 196 52 696 A1, EP 1 148 186 A1, GB 2 252 775 et GB 2 248 660.As examples of such bases, one can refer for example to publications NL 10 08 592, NL 94 01 555, DE 196 52 696 A1, EP 1 148 186 A1, GB 2 252 775 and GB 2 248 660.

Ce dernier document décrit un organe de verrouillage destiné à maintenir les pieds sur le socle. Cela permet de rendre plus difficile, pour des personnes non autorisées, de dégager les pieds du socle pour écarter les barrières ou palissades et de protéger plus efficacement le chantier ou la zone à délimiter. L'organe de verrouillage comporte une pièce qui est fixée par boulonnage sur le socle, ce qui rend sa pose et sa dépose pour l'ensemble des socles d'un chantier fastidieuse. De plus, la vis utilisée est susceptible de rouiller et de s'abímer sauf à utiliser de l'acier inoxydable, relativement coûteux.This last document describes a locking member intended to maintain the feet on the base. This makes it more difficult for unauthorized persons to to release the feet of the base to spread the barriers or fences and to protect more effectively the site or the area to be delimited. The locking member includes a part which is fixed by bolting on the base, which makes its installation and removal for all the bases of a tedious construction site. In addition, the screw used is likely to rust and damage except using relatively expensive stainless steel.

L'invention vise à proposer un moyen simple et perfectionné permettant de verrouiller des pieds de barrière sur un socle.The invention aims to provide a simple and improved means for lock barrier feet on a base.

L'invention atteint ce but grâce à un ensemble comportant :

  • un socle comportant au moins deux logements destinés à recevoir respectivement les pieds de deux barrières adjacentes destinées à être maintenues par le socle,
  • au moins un logement intermédiaire situé entre ces deux logements, destiné à permettre le passage d'un organe de verrouillage amovible, solidaire à son extrémité inférieure d'un élément de retenue destiné à être engagé sous le socle et à venir en appui contre sa face inférieure, et solidaire à son extrémité supérieure d'un élément de fixation sur les pieds.
The invention achieves this object thanks to an assembly comprising:
  • a base comprising at least two housings intended respectively to receive the feet of two adjacent barriers intended to be held by the base,
  • at least one intermediate housing located between these two housings, intended to allow the passage of a removable locking member, integral at its lower end with a retaining element intended to be engaged under the base and to come into abutment against its face lower, and secured at its upper end to a fastening element on the feet.

Le logement intermédiaire est avantageusement agencé de manière à pouvoir recevoir un pied de barrière ou de poteau.The intermediate housing is advantageously arranged so that it can receive a barrier or post foot.

Le logement intermédiaire est de préférence réalisé de manière à communiquer avec les autres logements, ce qui peut faciliter la fabrication du socle et permettre de réaliser plus facilement le logement intermédiaire pour qu'il puisse recevoir un pied de barrière ou de poteau.The intermediate housing is preferably made so as to communicate with the other housings, which can facilitate the manufacture of the base and allow more easily make the intermediate housing so that it can receive a foot fence or post.

L'organe de verrouillage peut par exemple comporter un corps allongé et l'élément de fixation comporter un double collier conventionnel, destiné d'une part à être fixé sur ce corps allongé, par exemple par boulonnage, et d'autre part à enserrer les pieds.The locking member may for example comprise an elongated body and the fixing element comprise a conventional double collar, intended on the one hand to be fixed on this elongated body, for example by bolting, and on the other hand to enclose the feet.

L'élément de retenue peut par exemple être constitué par une plaque sur laquelle se raccorde perpendiculairement le corps allongé de l'organe de verrouillage.The retaining element may for example consist of a plate on which is connected perpendicularly to the elongated body of the locking member.

Grâce à l'invention, on dispose d'un moyen efficace et économique pour verrouiller deux pieds de barrière ou de palissade sur un socle et rendre plus difficile l'accès à un chantier ou à une zone à protéger.Thanks to the invention, an efficient and economical means is available for lock two barrier or palisade feet on a base and make it more difficult access to a site or to an area to be protected.

Le socle comporte de préférence une enveloppe en matière plastique remplie de béton.The base preferably includes a plastic envelope filled of concrete.

Cette enveloppe est avantageusement réalisée avec d'une part au moins deux logements destinés respectivement à accueillir les pieds et d'autre part le logement intermédiaire par lequel communiquent ces deux logements.This envelope is advantageously produced with on the one hand at least two housings intended respectively to receive the feet and on the other hand the accommodation intermediary through which these two dwellings communicate.

De préférence, l'enveloppe est réalisée par soufflage mais on ne sort pas du cadre de l'invention lorsque l'enveloppe est réalisée autrement, par exemple par rotomoulage ou par moulage par injection de deux demi-pièces soudées ensuite.Preferably, the envelope is produced by blowing but it does not leave the framework of the invention when the envelope is produced otherwise, for example by rotational molding or by injection molding of two half-pieces then welded.

Le logement intermédiaire peut par exemple présenter une section sensiblement carrée ou rectangulaire lorsque le socle est observé de dessus, les logements destinés à recevoir les pieds étant par exemple de section circulaire et de diamètre légèrement supérieur à 40 mm.The intermediate housing may for example have a section substantially square or rectangular when the base is observed from above, the housings intended to receive the feet being for example of circular section and diameter slightly greater than 40 mm.

Le logement intermédiaire peut présenter une section rectangulaire de dimensions légèrement supérieures à 80 x 40 mm, et les angles aux jonctions entre le logement intermédiaire et les autres logements peuvent être agencés de manière à permettre au logement intermédiaire de recevoir un pied de section circulaire, notamment de 60 mm de diamètre.The intermediate housing may have a rectangular section of dimensions slightly greater than 80 x 40 mm, and the angles at the junctions between the intermediate housing and the other housings can be arranged so as to allow the intermediate housing to receive a foot of circular section, in particular 60 mm in diameter.

L'invention pourra être mieux comprise à la lecture de la description détaillée qui va suivre, d'exemples non limitatifs de mise en oeuvre de celle-ci, et à l'examen du dessin annexé, sur lequel :

  • la figure 1 représente, de manière schématique et partielle, un organe de verrouillage en place dans un socle,
  • la figure 2 représente isolément et de manière schématique en coupe longitudinale selon II-II de la figure 1, l'organe de verrouillage, et
  • la figure 3 représente de manière schématique, en perspective de dessus, un exemple de socle pouvant avantageusement être utilisé conjointement avec l'organe de verrouillage de la figure 1.
The invention will be better understood on reading the detailed description which follows, of nonlimiting examples of implementation thereof, and on examining the appended drawing, in which:
  • FIG. 1 shows, schematically and partially, a locking member in place in a base,
  • FIG. 2 represents in isolation and schematically in longitudinal section along II-II of FIG. 1, the locking member, and
  • FIG. 3 schematically represents, in perspective from above, an example of a base which can advantageously be used in conjunction with the locking member of FIG. 1.

On a représenté à la figure 1 un socle 1 et un organe de verrouillage 2 destiné à verrouiller sur le socle 1 deux pieds P de barrière engagés dans des logements respectifs 3 et 4 du socle 1. Les pieds P sont constitués par exemple par des tubes métalliques dont le diamètre extérieur est voisin de 40 mm.There is shown in Figure 1 a base 1 and a locking member 2 for lock on the base 1 two feet P of barrier engaged in respective housings 3 and 4 of the base 1. The feet P are constituted for example by metal tubes, the outside diameter is close to 40 mm.

L'organe de verrouillage 2 comporte un corps allongé 6 constitué par exemple par une tige plate métallique, et une plaque de base 9 sur laquelle se raccorde perpendiculairement la tige plate 6 à son extrémité inférieure, la tige 6 étant par exemple fixée par soudure à la plaque 9.The locking member 2 comprises an elongated body 6 constituted for example by a flat metal rod, and a base plate 9 to which is connected perpendicularly the flat rod 6 at its lower end, the rod 6 being for example fixed by welding to the plate 9.

La tige 6 comporte à son extrémité supérieure un perçage 14 permettant la fixation sur celle-ci d'un double collier 15 comportant deux brides, dont seule l'une 16 est apparente sur la figure 1.The rod 6 has at its upper end a hole 14 allowing the fixing on the latter of a double collar 15 comprising two flanges, of which only one 16 is shown in Figure 1.

Chacune de ces brides comporte deux logements demi-circulaires agencés chacun pour venir s'engager sur un pied P.Each of these flanges has two semicircular housings arranged each one to come to engage on a foot P.

Le double collier 15 est par exemple fixé sur la tige plate 6 au moyen d'un boulon 19 introduit dans le perçage 14 et nécessitant un outil spécial pour être dévissé.The double collar 15 is for example fixed on the flat rod 6 by means of a bolt 19 inserted into the hole 14 and requiring a special tool to be unscrewed.

Conformément à un aspect de l'invention, un logement intermédiaire 17 est prévu sur le socle 1 entre les logements 3 et 4 pour le passage de la tige 6.According to one aspect of the invention, an intermediate housing 17 is provided on the base 1 between the housings 3 and 4 for the passage of the rod 6.

Pour utiliser l'organe de verrouillage 2, celui-ci est introduit par-dessous dans le socle 1 de manière à ce que la plaque 9 vienne en appui contre sa face inférieure et que la tige 6 traverse le logement 17.To use the locking member 2, it is introduced from below into the base 1 so that the plate 9 comes to bear against its underside and that the rod 6 passes through the housing 17.

Ensuite, les pieds P sont introduits dans les logements respectifs 3 et 4, puis le double collier 15 est mis en place de manière à enserrer les pieds P et être fixé sur la tige 6.Then, the feet P are introduced into the respective housings 3 and 4, then the double collar 15 is put in place so as to grip the feet P and be fixed on the rod 6.

L'organe de verrouillage 2 empêche alors de dégager les pieds P qui restent solidaires du socle 1.The locking member 2 then prevents releasing the remaining feet P integral with the base 1.

Le socle 1 peut être réalisé entièrement en béton ou en matière plastique comme c'est le cas sur la figure 1. Toutefois, les logements 3, 4 et 17 sont de préférence réalisés comme illustré sur la figure 3 par conformation d'une enveloppe en matière plastique, cette enveloppe étant remplie de béton coulé à l'intérieur, le béton venant entourer les logements 3, 4 et 17. Cette enveloppe est avantageusement réalisée par soufflage.The base 1 can be made entirely of concrete or plastic as is the case in FIG. 1. However, the housings 3, 4 and 17 are preferably produced as illustrated in FIG. 3 by shaping an envelope of material plastic, this envelope being filled with concrete poured inside, the concrete coming surround the housings 3, 4 and 17. This envelope is advantageously produced by blowing.

Le logement 17 peut être réalisé avec une section rectangulaire, de grand côté parallèle à l'axe longitudinal X du socle, et être par exemple de dimensions légèrement supérieures à 40 x 80 mm, de manière à pouvoir recevoir un pied de section rectangulaire de côtés 40 x 80 mm.The housing 17 can be made with a rectangular section, with a long side parallel to the longitudinal axis X of the base, and for example be of dimensions slightly larger than 40 x 80 mm, so that it can receive a rectangular section foot 40 x 80 mm sides.

Dans l'exemple considéré, les angles 18 à la jonction des logements 3, 4 et 17 sont agencés de manière à permettre de recevoir également dans le logement 17 un pied de section circulaire de diamètre 60 mm, ce qui confère au socle un caractère multifonction.In the example considered, the angles 18 at the junction of the housings 3, 4 and 17 are arranged so as to receive also in the housing 17 a foot circular section with a diameter of 60 mm, which gives the base a multifunctional character.

D'autres logements peuvent encore être réalisés sur le socle 1, comme on peut le voir sur la figure 3.Other housings can also be made on the base 1, as can be see it in figure 3.

Bien entendu, l'invention n'est pas limitée aux exemples qui viennent d'être décrits.Of course, the invention is not limited to the examples which have just been described.

En particulier, les logements 3 et 4 recevant les pieds peuvent être réalisés avec d'autres formes encore, de même que le logement intermédiaire 17.In particular, the housings 3 and 4 receiving the feet can be made with still other forms, as well as the intermediate housing 17.

Sur la figure 3, on voit que le socle 1 comporte à proximité de son extrémité gauche un ensemble de logements communiquant permettant également le passage d'un organe de verrouillage 2 tel que celui qui vient d'être décrit.In Figure 3, we see that the base 1 has near its end left a set of housing communicating also allowing the passage of a locking member 2 such as that just described.

Dans toute la description y compris les revendications, l'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, including the claims, the expression "Comprising a" should be understood as being synonymous with "comprising at least a ”, unless otherwise specified.
