Abstract

The device has an elastic material block (2) vulcanized on a support plate (1) and equipped with a tapping (4) at the center of the block, and a section having a threaded rod which inserts into the tapping. The rod permits bending of the section during light impacts and is pulled out from the tapping during violent impact. The rod allows the section to be detached from the block and the support plate.

Description

La présente invention a pour objet un dispositif de protection contre lesThe subject of the present invention is a device for protecting against

chocs mécaniques constitué d'une platine disposée sur le sol, d'un bloc de matière élastique inséré sur la platine et d'un profilé inséré sur le bloc de matière élastique.  mechanical shock consists of a plate disposed on the ground, a block of elastic material inserted on the plate and a profile inserted on the block of elastic material.

On connaît déjà différentes sortes de dispositifs de protection des chocs mécaniques. Par exemple, le brevet FR 2 304 722 divulgue une borne inclinable lors d'un impact, cette borne étant fixée sur le sol par l'intermédiaire d'une matière déformable élastiquement.  Various types of devices for protecting mechanical shocks are already known. For example, patent FR 2 304 722 discloses a tilting terminal during an impact, this terminal being fixed on the ground by means of an elastically deformable material.

Le brevet FR 1 482 473 décrit un poteau inclinable lié au sol par un embout, grâce à une pièce intermédiaire souple s'insérant dans l'embout et rigidifiant le poteau.  The patent FR 1 482 473 describes a tilting pole bound to the ground by a tip, thanks to a flexible intermediate piece inserted into the tip and stiffening the pole.

Ce type de dispositif est efficace lors d'un choc faible car il permettra la flexion du poteau, mais présente l'inconvénient d'arracher la structure sur laquelle il est fixé lors d'un choc violent.  This type of device is effective during a weak shock because it will bend the post, but has the disadvantage of tearing the structure on which it is fixed during a violent impact.

L'invention a permet de remédier à cet inconvénient par arrachement de la partie supérieure du dispositif, la partie inférieure restant fixée au sol.  The invention has remedied this drawback by tearing of the upper part of the device, the lower part remaining fixed to the ground.

Conformément à l'invention, on propose un dispositif de protection contre les chocs mécaniques divers composé de trois parties: une platine disposée sur le sol - un bloc de matière élastique, du type dit silentbloc inséré sur la platine et muni d'un taraudage un profilé inséré sur le bloc de matière élastique Le profilé est muni d'une tige filetée qui va s'insérer dans le taraudage du bloc de matière élastique. Le profilé peut être incliné lors d'un choc léger par l'intermédiaire du bloc de matière élastique. Lors d'un effort plus important, il pourra être arraché du bloc de matière élastique par l'intermédiaire du taraudage qui se désolidarisera de la tige filetée du profilé.  According to the invention, there is provided a device for protection against various mechanical shocks composed of three parts: a plate disposed on the ground - a block of elastic material, the so-called silentbloc type inserted on the plate and provided with a thread a profile inserted on the block of elastic material The profile is provided with a threaded rod which will be inserted into the tapping of the block of elastic material. The profile can be tilted during a light impact through the block of elastic material. During a greater effort, it may be torn from the block of elastic material through the tapping which will separate from the threaded rod of the profile.

On comprendra mieux l'invention à l'aide de la description faite ci-après en référence aux dessins annexés sur lesquels: - la figure 1 est une vue globale du dispositif de protection - la figure 2 est une vue de l'association de la platine et du bloc de matière élastique - la figure 3 représente le profilé Le dispositif de protection des chocs mécaniques est composé d'une platine 1 fixée au sol par des moyens connus, tels que des boulons ou autres. Sur cette platine 1 se trouve le bloc de matière élastique 2. Selon une caractéristique avantageuse de l'invention, le bloc de matière élastique 2 sera vulcanisé sur la platine 1, afin d'améliorer sa résistance tout en lui conservant son élasticité. De plus, ce bloc 2 peut former des insertions en forme de queue d'aronde dans la platine 1 (non représenté).  The invention will be better understood by means of the description given hereinafter with reference to the appended drawings in which: FIG. 1 is an overall view of the protection device; FIG. 2 is a view of the association of the platinum and the block of elastic material - Figure 3 shows the profile The mechanical shock protection device is composed of a plate 1 fixed to the ground by known means, such as bolts or other. On this plate 1 is the block of elastic material 2. According to an advantageous characteristic of the invention, the block of elastic material 2 will be vulcanized on the plate 1, to improve its strength while retaining its elasticity. In addition, this block 2 can form dovetail-shaped insertions in the plate 1 (not shown).

Selon une autre caractéristique avantageuse de l'invention, ce bloc de matière plastique 2 sera en caoutchouc, naturel ou synthétique. II pourra également être en polymère élastomère.  According to another advantageous characteristic of the invention, this block of plastic material 2 will be made of rubber, natural or synthetic. It may also be elastomeric polymer.

Au centre du bloc de matière élastique 2, se trouve un taraudage 4, comme on peut le voir sur la figure 2. Ce taraudage 4 pourra avoir un diamètre et une profondeur variables, selon les caractéristiques de résistance aux chocs souhaitées.  In the center of the elastic material block 2, there is a tapping 4, as can be seen in Figure 2. This tapping 4 may have a variable diameter and depth, depending on the desired impact resistance characteristics.

Sur le bloc de matière élastique 2 se trouve un profilé 3. Ce dernier aura indifféremment une forme cylindrique, parallélépipédique ou autre. II est muni d'une tige filetée 5 qui va s'insérer dans le taraudage 4 du bloc de matière élastique 2. Lors d'un choc léger, cette tige 5 va permettre la flexion de l'ensemble du dispositif de protection. Par contre, lors d'un impact violent, cette tige 5 va s'arracher du taraudage 4, et par conséquent du bloc de matière élastique 2. Ceci permettra au profilé 3 de se détacher de la structure constituée par le bloc de matière élastique 2 et la platine 1. Cette dernière restera fixée au sol, et évitera ainsi une dégradation de ce dernier.  On the elastic material block 2 is a profile 3. The latter will have indifferently a cylindrical shape, parallelepiped or other. It is provided with a threaded rod 5 which will be inserted into the tapping 4 of the elastic material block 2. During a slight impact, this rod 5 will allow the bending of the entire protective device. On the other hand, during a violent impact, this rod 5 will tear off the tapping 4, and therefore the block of elastic material 2. This will allow the section 3 to detach from the structure constituted by the block of elastic material 2 and platinum 1. The latter will remain fixed on the ground, and thus avoid a degradation of the latter.

La platine 1 pourra être réalisée indifféremment en inox, composites, aluminium ou tout autre matériau adapté. Elle pourra avoir une forme arrondie, carrée ou autre.  The plate 1 can be made indifferently of stainless steel, composites, aluminum or any other suitable material. It may have a rounded shape, square or other.

Le bloc de matière élastique 2 aura préférentiellement une forme conique assurant une bonne étanchéité avec le profilé lors du vissage.  The block of elastic material 2 will preferably have a conical shape ensuring a good seal with the profile during screwing.

Ce dispositif de protection contre les chocs mécaniques peut être utilisé dans divers espaces, tels que les industries, les habitations de particuliers, les voiries et locaux divers.  This device for protection against mechanical shocks can be used in various spaces, such as industries, homes, roadways and various premises.

Bien que l'invention ait été décrite avec des moyens de réalisation particuliers, elle comprend tous les équivalents techniques des moyens décrits.  Although the invention has been described with particular embodiments, it includes all the technical equivalents of the means described.
