Definitions

  • RV recreational vehicle
  • a motor home or travel trailer, and the like with a slide out room for the purpose of selectively expanding the interior space of the RV.
  • RV's typically are designed to accommodate such slide out rooms at the outset. Installation of such a slide out room into an existing RV not designed to accommodate the slide out room at the outset would involve substantial modification of the RV's structure, which modification might be neither practical nor cost effective. This may be especially true where the RV is based on a conventional panel van that is subject to relevant government crash and/or emissions certifications that might be voided in the wake of substantial modifications to the van's body structure, for example, creating a large aperture in the body structure configured to slidably receive the slide out room.

  • the room 20 could be extended by operating the motor 58 to rotate the torque shaft 50 and the first and second pinion gears 52, 54 disposed thereon, thereby driving the first and second gear racks 46, 48.
  • the extent to which the slide out room 20 may be extended through the frame 34 and the vehicle 12 may be limited by the depth of the slide out room and the length and placement of the gear racks 46, 48 on the sidewalls 26, 28 of the slide out room (or the configuration of an alternative drive mechanism) and the point of installation of the assembly 10 within the vehicle 12.

Abstract

L'invention concerne un ensemble formant cellule de type rallonge escamotable à des fins d'installation dans un véhicule à moteur, comprenant une cellule de type rallonge escamotable (20) ayant des première et deuxième parois latérales opposées (26) et un cadre (34) configuré pour recevoir de manière coulissante la cellule de type rallonge escamotable (20). Des crémaillères à engrenages supérieure et inférieure (46, 48) sont disposées sur chacune des première et deuxième parois latérales. Des premier et deuxième mécanismes d'entraînement comprenant des pignons supérieur et inférieur (52, 54) sont attachés à des premier et deuxième montants (40, 42) de la cellule de type rallonge escamotable. Les pignons supérieur et inférieur viennent se mettre en prise avec les crémaillères à engrenages supérieure et inférieure respectives. Le cadre peut être installé dans un véhicule à moteur adjacent à une porte (18) du véhicule de telle sorte que l'ensemble est entièrement contenu à l'intérieur d'une partie intérieure du véhicule et la porte peut être fermée quand la cellule de type rallonge escamotable est dans une position rétractée. La cellule de type rallonge escamotable peut être étendue au travers de la porte du véhicule quand la porte est ouverte. L'ensemble peut être installé dans un véhicule bénéficiant d'une homologation gouvernementale appropriée concernant les collisions et/ou les émissions, et sorti de celui-ci, sans annulation de l'homologation.
