DESCRIPTION OF THE INVENTION

[0065] The tonneau cover opening and locking system, object of the present invention, comprises a profile (10) provided with a set of actuators (20) and locking structures (30) arranged at the ends of the profile and fixed by projections (31) to the holes (16), with the set of profile (10) and structures (30) being connected to the terminals (80) of the side profiles, which allows for easy opening and closing of the cover.

[0066] The profile (10) has a lower spacing (11) wherein the tarpaulin will be fitted through a plastic profile (12) sewn on the tarpaulin and a cavity (13) for arranging a second sealing profile (14). In the posterior portion, the profile has spacing (15) provided by projections (151) and (152) that allow the fitting and displacement of the actuators (20).

[0067] The profile (12) is fitted laterally in the spacing (11) of the profile (10) allowing the tarpaulin to be fixed to the structure. The fixation of the profile (12) to the tarpaulin (200) occurs by sewing so that an edging (121) is used, arranged on the edge of the tarpaulin with the profile (12), ensuring greater resistance to the seam and preventing the mesh from falling apart.

[0068] The profile (14) is fitted in the spacing (13) of the profile (10) upwardly, ensuring greater sealing at the time of closing.

[0069] The pair of actuators (20) is formed by two symmetrical parts and describes a projection (21) provided with a groove (22) that allows the fitting with the projection (152) and a groove (23) that fits with the projection (151) of the profile (10), said projection (21) having an ergonomic shape for the positioning of the user's fingers. The actuators (20) have projections (24) provided with holes (241) and projections (25) provided with holes (251), said projections (24) and (25) allowing the fixing and positioning of the system actuation rods.

[0070] The actuators (20) are fitted laterally along the profile (10) and tracked through the projections (151) and (152) positioned with the grooves (22) and (23), as shown in FIG. 7.

[0071] Locking structures (30) are fitted to the ends of the profile (10) provided with projections (31) that allow the fitting with the profile (10) through a click, so that the projections (31) are provided with a matching tooth that fit with the holes (16) arranged in the profile, facilitating the fixing and fitting system between the structures.

[0072] The locking structure (30) is endowed with projections (32) spaced apart from each other that allow the positioning and movement of the structure (40) by 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).

[0073] The structure (30) is provided in its lower portion by a relief (33) that allows the movement of the structure (40) and a relief (34) that accommodates the auxiliary part (60) for fixing the tarpaulin and arrangement of the sealing profile (14).

[0074] The auxiliary part (60) is provided with a projection (61) that fits together with the relief (34) of the structure (30) in order to allow its fixation using screws (not shown). The part (60) is sewn to the tarpaulin and when fixed allows the locking, and between the tarpaulin and the part (60) will be the part (30), and in addition the part (60) is provided with grooves (62) that allow the fitting of the sealing profile (14).

[0075] The structure (40) is provided with a bas-relief (41) that allows 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 to the terminal (80) which is fitted to the side profile, in order to allow the locking. In the central portion of the structure (40) an opening (43) is arranged that allows the positioning of the latch pin (50), said opening (43) having a projection (431) for positioning the spring. The frame (40) is fitted to the frame (30) by sliding between the projections (32) and next to the relief (33).

[0076] The structure (40) is also provided with an oblong hole (44) arranged between the projection (42) and the opening (43), which receives the locking pin (30A).

[0077] 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). In the lower portion there is a bas-relief (53) for the positioning of the spring (531). At the opposite end, it describes a projection (54) that allows the locking of the structure to the terminal (80) next to the spacing (83).

[0078] The operating system of the locking structures (30) occurs through the positioning of the structure (40) between the projections (32) so that the opening (43) is positioned close to the rectangular opening (321) for the placement of the latch pin (50) next to the hole (43), positioning the metal pin (30A) in the hole (322) located in the rods (32) and matching with the hole (322) of the part (30) and the oblong (44) of the part (40), preventing the system from dismantling, in addition to limiting the movement of the part (40) that moves slidingly with the pin (30A).

[0079] Thus, the pin (30A) is what guarantees the locking of the structure (40) with the structure (30), so that the pin (30A) serves as a limiter to the movement of the structure (40).

[0080] The spring (411) allows the tensioning of the structure (40) with the structure (30) in order to move the profile (10) away from the terminal (80) and, consequently, from the rectangular structure of the cover, which allows to keep the tarpaulin always stretched. When the latch pin (50) is activated, it presses the spring (531) to the projection (431) so that the pin (50) is released from the terminal (80), releasing the cover locking system.

[0081] The locking structures (30) are connected to the terminals (80) of the cover side profiles, said structures (80) having projections (81) that allow the fitting with the side profile (10A) through a click, so that the projections (81) are provided with teeth that fit with holes (16A) arranged in the profile, facilitating the fixing and fitting system between the structures.

[0082] The frames (80) are provided with a spacing (82) for positioning the projection (42) of the frame (40) and a spacing (83) for positioning the projection (54) of the latch pin (50).

[0083] In the lower portion, the structures (80) have a spacing (84) for the positioning of an EVA part (85), said spacing (84) having a tooth (841) that allows fitting and fixing the part (85). The EVA part (85) is fitted together with the structure (80) and side profile (10A), as shown in FIGS. 30, 31 and 32.

[0084] The actuation system between the structures (30) connected to the profile (10) and the structures (80) connected to the side profiles (10A) occurs through the actuation of the actuators (20) by the user, so that with the fingers, thumb and indicator, under the profile (10), will make the drive performing the movement against the two parts (20).

[0085] The actuators (20) are positioned in pairs in the central portion of the profile (10), so that the total release of the system can take place by the actuation of only one pair of actuators (20) or by the simultaneous actuation of both pairs of actuators. This drive system is only possible due to the form of interconnection between the actuators (20), sets of rods (70) and pins (50).

[0086] Actuators (20) are modular, which allows them to be applied and adapted according to the need for using the cover model, allowing for greater variability in the system's implementation. Furthermore, the actuators (20) can be positioned one at each end, being able to be actuated by both hands in the case of a low-cost version.

[0087] The rod fixation system (70), as shown in the images, is performed by positioning the rod (70A) to the pin (50), arranged in the left portion, and connected to the first actuator (20) so that the rod (70A) is positioned with the projections (25) and fixed together with the detail (251). The rod (70B) is positioned on the projections (24) of and fixed to the detail (241) of the first, in the second the rod (70B) will be fitted only to the projection (24) and in the third actuator (20) the rod will be fitted to the projection (24) and also in detail (241). The rod (70C) is positioned on the projections (25) of the second, third and fourth actuator (20) so that the rod (70C) functions in a manner similar to the rod (70B). The rod (70D) is positioned on the projections (24) and also on the detail (241) of the fourth actuator (20) up to the pin (50), arranged in the right portion, of the profile (10).

[0088] The actuator system (20), as shown in the images, will have four rods (70A), (70B), (70C) and (70D) with two rods being connected to the pins (50) and the other two connected between the actuators (20) which allows the transmission of movement.

[0089] The rods (70A), (70B), (70C) and (70D) are fixed with the projection (24) and holes (241) that allow the locking the ends of each rod and projection (25), and holes (251) that allow locking the ends of each rod, so that the end of the rod is bent along the holes.

[0090] On the other hand, the actuation system by actuators (20) and rods has a modular characteristic, as it allows the use of one (1) or more actuators (20) in the same profile (10), according to the application needed and type of cover that is being used, allowing the opening way to be varied with one or two hands depending on the distance between the parts (20).
