Title (EN) LABOR-SAVING TRUCK TAILGATE DEVICE SET
(FR) ENSEMBLE DISPOSITIF DE HAYON DE CAMION ÉCONOMISEUR DE TRAVAIL
Abstract:
(EN) A labor-saving truck tailgate device set comprises a tailgate bracket (42, 44), a spindle-containing spring set (555), a spring-end supporting bracket (80) and further comprises a damper set (444) and a damper bracket (40, 41). The spindle-containing spring set (555) is connected to the tailgate bracket (42, 44) by inserting the coiled spring (15) into the spindle (74) so that one end of the coiled spring (15) is held onto the tailgate bracket (40, 41) and the other end of the coiled spring (15) is connected to the spring-end supporting bracket (80) by means of having said spring-end supporting bracket (80) held onto the truck body (121). The spindle (74) is positioned on the same center as the spindle (46) of the tailgate (111) and is further comprising the damper set (444) which is connected to the truck body (121) and the tailgate (111) via bracket (40,41). The end of the spring (15) that is connected to the tailgate bracket (42, 44) rotates in the same direction as the tailgate (111) during opening. The end of spring (15) that supported on the spring-end supporting bracket (80) creates the strain via the rotational force of the coiled spring (15) and the retardation of the damper (444) in order to reduce the shock during opening the tailgate (111) and, at the same time, the accumulating strain or tension inside the spring (15) gets converted into the recoil force during closing of the tailgate (111).
(FR) La présente invention concerne un ensemble dispositif de hayon de camion économiseur de travail comprenant un support de hayon, un ensemble ressort contenant un axe, un crochet soutenant une extrémité de ressort, l'invention concernant en outre un ensemble amortisseur doté de crochets permettant de raccorder le crochet de hayon au hayon. L'ensemble ressort contenant un axe est raccordé au crochet de hayon en insérant le ressort enroulé dans l'axe pour qu'une extrémité du ressort enroulé soit maintenue sur le crochet de hayon et que l'autre extrémité du ressort enroulé soit raccordée au crochet de support d'extrémité de ressort grâce au maintien dudit crochet de support d'extrémité de ressort sur le corps du camion. L'axe est positionné sur le même centre que l'axe du hayon et comprend en outre l'ensemble amortisseur qui est raccordé au corps de camion et au hayon par l'intermédiaire du crochet. L'extrémité du ressort raccordée au crochet de hayon tourne dans le même sens que le hayon pendant l'ouverture. Ladite extrémité de ressort qui supporte le crochet de support d'extrémité de ressort crée la contrainte par la force de rotation du ressort enroulé et le retard de l'amortisseur afin de réduire le choc pendant l'ouverture du hayon. Simultanément, la contrainte ou la tension s'accumulant à l'intérieur du ressort est convertie en force de recul pendant fermeture du hayon.
