An extendable load bearing apparatus that protects the bed of a pickup truck from damage caused by unloading and loading objects into and out of the bed, and that protects the bed from otherwise compromising weather-related elements. The apparatus includes a load bearing tray that has longitudinal sides, a forward end, and a rear end, and that has downwardly projecting tray supports extending substantially along the longitudinal sides of the tray. The apparatus also includes a plurality of rollers each housed within a roller bracket and secured to a workpiece. Each of the plurality of rollers is in supporting relationship with one of the pair of downwardly extending tray supports, At least one axle extends transversely from each of the pair of downwardly extending tray supports. A wheel is mounted in rotatable relationship to each of the axles to facilitate movement of the load bearing tray in a longitudinal direction. A pair of channel brackets is secured to the workpiece, with each of the wheels being housed within one of the channeled brackets to limit movement of the load bearing sliding tray in a longitudinal direction. The rollers and the wheels function as load bearing members that support the sliding tray to maximize the load bearing capability of the sliding tray regardless of the position of the tray in relation to the pair of channel brackets.
Cette invention concerne un plan de chargement télescopique servant à protéger la plate-forme d'une camionnette contre les dommages causées au chargement/déchargement du véhicule et contre les effets nuisibles des intempéries. Le plan de chargement comprend des longerons latéraux, des traverses avant et arrière et des pièces d'appui orientées vers le bas et faisant sensiblement toute la longueur du plan de chargement. Il comprend aussi une série de galets logés dans des chemins de roulement fixés sous les deux pièces d'appui précitées et servant à soutenir ces dernières. Une série d'axes sont montés perpendiculairement sur la face extérieure de ces pièces d'appui pour recevoir des roues tournant librement et destinées à faciliter le déplacement du plan de chargement. Un profilé en U fixé à la pièce formant chemin de roulement des galets précités sert de rail de guidage des roues pour limiter le déplacement du plan de chargement dans le sens transversal. Les galets et roues interposés entre le plan de chargement et la plate-forme de la camionnette contribuent à répartir le poids du chargement, ce qui permet de maximiser la charge peu importe la position longitudinale du plan de chargement le long des profilés de guidage.
