Abstract

The pneumatic seal has two pneumatic joint seals (1) fixed to surround the two doors (3) of the container. The seals are pressurized with air during closure of the doors and vice versa. There is a solenoid valve (5) controlled by micro-switches (6). the pressurized air is supplied form the vehicle pneumatic brake reserve circuit.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un dispositif améliorant, à coup sûr, l'étanchéité des caisses frigorifiques et surtout le confort d'utilisation au quotidien du chauffeur livreur de par la facilité d'ouverture des portes.  The present invention relates to a device improving, for sure, the tightness of the refrigerated boxes and above all the comfort of daily use of the delivery driver by the ease of opening the doors.

L'étanchéité des caisses frigorifiques est obtenue traditionnellement par des joints fixes à lamelles qui, à force de friction contre l'encadrement, s'use et détériore le taux d'étanchéité, de plus, de par l'ajustement de la jointure (friction serrée) par rapport à l'encadrement les portes sont en général très dures à ouvrir.  The tightness of the refrigerated boxes is traditionally obtained by fixed seals with strips which, by friction force against the frame, wear and deteriorate the sealing rate, moreover, by the adjustment of the joint (friction tight) compared to the frame, the doors are generally very hard to open.

Le dispositif selon l'invention permet de remédier à ces inconvénients. Il comporte en effet selon une première caractéristique deux joints pneumatiques (un par porte), ayant la particularité de se remplir d'air, comme leur nom l'indique, et une fois gonflés, les portes étant fermées, ils épousent parfaitement la forme de l'encadrement.  The device according to the invention overcomes these drawbacks. According to a first characteristic, it indeed comprises two pneumatic seals (one per door), having the particularity of filling with air, as their name suggests, and once inflated, the doors being closed, they perfectly match the shape of framing.

Particularité ne pouvant que parfaire la tenue de la température à l'intérieur de la caisse. Etant prouvé que durant de grosses chaleurs extérieures l'échange de température intérieur/extérieur arrive à passer. D'où des modifications au niveau des réglages de l'appareil produisant le froid de 2 à 3 en dessous de 0 par rapport à l'accoutumé. De ce fait, le frigo est sollicité plus que la normale et automatiquement sa consommation s'accroît. D'autre part encore une fois, ce dispositif améliore grandement le confort d'utilisation au quotidien du chauffeur livreur en lui facilitant la manipulation des portes.  Special feature that can only improve the temperature resistance inside the body. It has been proven that during heavy outdoor heat the indoor / outdoor temperature exchange can pass. Hence changes in the settings of the device producing the cold from 2 to 3 below 0 compared to the usual. As a result, the fridge is used more than normal and automatically its consumption increases. On the other hand once again, this device greatly improves the comfort of daily use of the delivery driver by facilitating the handling of the doors.

A quelques petits détails prêts, le dispositif complet est celui présenté dans ce dossier.  With a few small details ready, the complete system is the one presented in this file.

Les schémas annexés illustrent l'invention :
La figure 1 représente la disposition du joint sur les portes avec une vue en coupe de la porte avec le joint. The attached diagrams illustrate the invention:
Figure 1 shows the arrangement of the seal on the doors with a sectional view of the door with the seal.

La figure 2 représente le joint en coupe avec son blindage en acier tressé
La figure 3 représente le dispositif complet avec tous les éléments qui en assurent le fonctionnement. Figure 2 shows the joint in section with its braided steel shield
Figure 3 shows the complete device with all the elements that ensure its operation.

En référence à ces dessins le dispositif comporte deux joints pneumatiques (1) emboîtés et collés dans chacune des deux portes (3), la partie inférieure du joint étant emboîtée et collée au fond d'une gorge (2) (figure 1) prévue à cet effet.  With reference to these drawings, the device comprises two pneumatic seals (1) fitted and glued into each of the two doors (3), the lower part of the seal being fitted and glued to the bottom of a groove (2) (FIG. 1) provided for this effect.

Ces deux joints sont alimentés en air par l'équipement pneumatique du véhicule (9), servant au freinage. Le remplissage en air des joints se produit une fois les portes fermées, déclenché par une action manuelle sur un micro-contact (6) placé soit sur le tableau de bord du camion, soit dans l'une des deux poignées d'ouverture de porte. Le micro-contact étant un bouton poussoir, une deuxième impulsion sur le bouton poussoir provoquant l'effet inverse c'est-à-dire la vidange des joints (1) de l'air pour permettre l'ouverture des portes (3).  These two seals are supplied with air by the pneumatic equipment of the vehicle (9), used for braking. The air filling of the seals occurs once the doors are closed, triggered by manual action on a micro-contact (6) placed either on the dashboard of the truck, or in one of the two door opening handles . The microswitch being a push button, a second impulse on the push button causing the opposite effect, that is to say the emptying of the joints (1) of the air to allow the doors (3) to open.

<Desc/Clms Page number 2> <Desc / Clms Page number 2>

Dans la forme de réalisation selon la figure 3, le remplissage des deux joints en air de même que la vidange est commandée par une ou plusieurs électrovannes (5) elles- mêmes commandées par le micro-contact (6).  In the embodiment according to FIG. 3, the filling of the two seals with air as well as the emptying is controlled by one or more solenoid valves (5) themselves controlled by the micro-contact (6).

La pression de l'air du dispositif étant contrôlée par un bloc régulateur de pression avec manomètre de contrôle (7) le débit d'air pouvant être augmenté ou diminué grâce à un robinet. (Ce bloc régulateur étant équipé d'un assécheur d'air évitant la condensation dans tout le système).  The air pressure of the device being controlled by a pressure regulator block with control manometer (7) the air flow can be increased or decreased by a tap. (This regulator block being equipped with an air dryer preventing condensation throughout the system).

Le dispositif complet en fonctionnement étant alimenté en air par la ou les cuves principales (8) servant aussi au freinage du véhicule, elles-mêmes alimentées par le compresseur du camion.  The complete device in operation being supplied with air by the main tank or tanks (8) also used for braking the vehicle, themselves supplied by the compressor of the truck.

Le dispositif selon l'invention pouvant être modifié comme énoncé plus haut dans certains détails. De même que les dimensions du dispositif qui dépendent du véhicule équipé. The device according to the invention can be modified as stated above in certain details. As well as the dimensions of the device which depend on the vehicle equipped.
