Tonneau cover opening and locking system

A tonneau cover opening and locking system characterized in that it describes a profile (10) provided with a lower spacing (11) wherein a plastic profile (12) sewn on the tarpaulin will be fitted, a cavity (13) for arranging a second sealing profile (14), a spacing (15) provided for engagement and displacement projections (151) and (152) of the actuators (20) and engagement holes (16) of the locking structures;

• the actuators (20) describing a projection (21) provided with a groove (22) that allows fitting together with the projection (152) and a groove (23) that fits together with the projection (151) of the profile (10), said projection (21) having an ergonomic shape for positioning the user's fingers, said actuators (20) have projections (24) provided with holes (241) and projections (25) provided with holes (251) and are laterally fitted together to the profile (10) and treaded through the projections (151) and (152) positioned along the grooves (22) and (23);
• the locking structure (30) is provided with projections (32) spaced apart from each other that allow the positioning of the structure (40) for fitting and fixing the locking assembly, said projections (32) having a rectangular shaped opening (321) for the positioning and displacement of the drive pin (50), said structure (30) which is provided in its lower portion by a relief (33) allowing the movement of the structure (40) and a relief (34) accommodating the auxiliary part (60) for fixing the tarpaulin and arrangement of the sealing profile (14), said auxiliary part (60) which is provided with a projection (61) that fits together with the relief (34) of the structure (30) so to allow its fixation through screws, and the tarpaulin is sewn;
• the structure (40) is provided with a bas-relief (41) allowing the positioning of the spring (411) that keeps the system tensioned and at the opposite end describes a projection (42) that allows the fitting of the structure together with the terminal (80) which is fitted to the side profile, and in the central portion of the structure (40) there is an opening (43) which allows the positioning of the latch pin (50), said opening (43) having a projection (431) for positioning the spring;
• the structure (40) is fitted to the structure (30) sliding between the projections (32) and next to the relief (33), and the structure (40) is also provided with an oblong hole (44), arranged between the projection (42) and opening (43) which receives the locking pin (30A);
• the latch pin (50) describes a projection (51) for fixing and fitting the drive rods (70) and projections (52) that allow the locking and fitting with the opening (43) of the structure (40) and in the lower portion it has a bas-relief (53) for positioning the spring (531), at the opposite end describes a projection (54) that allows the locking of the structure to the terminal (80) with the spacing (83);
• the actuator system (20) is provided with four rods (70A), (70B), (70C) and (70D) with two being connected to the pins (50) and the other two connected between the actuators (20) which allows the motion transmission, said rods (70A), (70B), (70C) and (70D) are fixed together with the projection (24) and holes (241) allowing the locking each rod ends and projection (25) and holes (251) allowing the locking of each rod ends, so that the rod end is bent with the holes;
• the terminals (80) are provided with a spacing (82) for positioning the projection (42) of the structure (40), a spacing (83) for positioning the projection (54) of the latch pin (50), a spacing (84) for positioning of an EVA part (85), said spacing (84) having a tooth (841) that allows the fitting and fixation of the part (85), and the EVA part (85) is fitted together with the structure (80) and side profile (10A).
