TH14769U - Tailgate lifting device for pickup trucks - Google Patents

Abstract

Page 1 of 1. Summary of the Invention: The pickup truck tailgate lift assist device consists of a base made of a polygonal rod, a connector with two opposing ends (end one and end two), a fastener for the connector to be attached to a slotted section, a torsion spring rod, a mounting plate, and a snap plate. The mounting plate is attached to holes on the rear edge of the truck bed. The base is attached to holes on the lower wall of the tailgate. The snap plate secures the torsion spring rod to the mounting plate. Hole one of the connector is fitted onto the polygonal rod and contains a spring tension adjustment device to adjust the spring tension of the torsion spring rod. The pickup truck tailgate lift assist device prevents the tailgate from rolling down forcefully when opening and reduces the effort required by the user when lifting the tailgate when closing it.

Page 1 of 2: Claims 1. Tailgate Lifting Device for Pickup Trucks Pickup trucks have a bed with a tailgate. The tailgate can be rotated open and closed. At the rear edge of the bed floor (34) there are several holes, and at the bottom wall of the tailgate there are several holes. The tailgate lifting device for a pickup truck consists of a base (53) which has a structure (59). The structure (59) is attached to the holes in the bottom wall of the tailgate and has a polygonal bar (60) protruding from the structure (59). A connector (54) has two opposite ends, one end and one end. The one end has a first hole (62), the cross-section of which is shaped to fit the cross-section of the polygonal bar (60). The two end has a second hole (63), the cross-section of which is shaped to fit the cross-section of the slot (77). The device that fastens the connector to the slot is unique in that it also consists of The torsion spring rod (55) consists of the slot for inserting into the second slot (63) of the connector (54), the first straight section (66), the first deflected section (67), the second straight section (68), the second deflected section (69), the third straight section (70), the truncated section (71), the downward pointing section (72), and the tension adjustment section (79). The mounting plate (56) consists of two opposing ends, namely the first end (80) and the second end (81). The first end (80) is attached to a hole at the rear edge of the truck bed section. The coupling plate (57) covers the third straight section (70) of the torsion spring rod. The coupling plate (57) is attached to the second end (81) of the mounting plate, and the tension adjustment device is used to adjust the spring tension of the torsion spring rod. 2. The tailgate lift device of a pickup truck, according to claim 1, has a nut attached to the rear edge of the bed section (34) at the position corresponding to the hole on the rear edge. The mounting plate (56) is attached to the hole on the rear edge of the bed section (34) by inserting a bolt (92) through the spring washer (93), through the washer (94), through the hole (82) at the first end (80) of the mounting plate, through the hole on the rear edge, and then tightening it to the nut. 3. A tailgate lifting device for a pickup truck, in accordance with claim 1, in which the lower wall (52) of the tailgate has a nut (42) welded to a position corresponding to a hole in the lower wall. The base (53) is secured to a hole in the lower wall (52) of the tailgate by inserting a bolt (46) through a hole (61) in the structure (59) through a hole in the lower wall of the tailgate and tightening it to the nut (42). Page 2 of 2. 4. The tailgate lift device of the pickup truck, according to claim 1, in which the cross-section of the polygonal bar (60) and the cross-section of the first hole (62) are hexagonal in shape. 5. A tailgate lift device for a pickup truck, according to claim 1, in which the cross-section of the second hole (63) and the cross-section of the insertion part (77) are cut in the shape of a circle. 6. The tailgate lift device of the pickup truck, as per claim 5, also consists of a threaded hole (64) located adjacent to the second hole (63). The device that fastens the connector to the insertion part consists of a grub screw (58). The grub screw is screwed through the threaded hole (64) until it makes contact and applies force to the insertion part (77). 7. A tailgate lift device for a pickup truck, according to claim 1, which at the second end (81) of the mounting plate (56) has two threaded rods (83), the plate (57) has holes (88) and (89) and a groove (91) between the holes (88) and (89). The groove (91) serves to cover the third linear section (70). The plate is attached to the mounting plate (56) by fitting the holes (88) and (89) of the plate into the threaded rods (83), after which a washer (99) is fitted and a nylon insert lock nut (98) is tightened onto the threaded rods (83). 8. Tailgate lift device for pickup trucks, in accordance with claim 1, which the mounting plate (56) also consists of a first baffle plate (84) and a second baffle plate (85), with a slot (87) between the two baffle plates. The mounting plate (56) has a threaded hole (86) located in line with slot (87). The spring tension adjuster consists of a screw (95) (96) and two spring washers (97), with the spring tension adjuster (79) located between the first baffle plate (84) and the second baffle plate (85) and located in line with the threaded hole (86). 9. The tailgate lifting device of a pickup truck, according to claim 1, which the downward pointing part (72) makes an angle of 90 degrees with the third straight part (70). 10. A tailgate lifting device for a pickup truck, according to claim No. 1, whose structure (59) consists of three walls.
