Definitions

• Present invention relates to a pre-locking system maintaining rear bumper assemblies on vehicle platforms of trailers, semi-trailers and trucks that are used for road haulage at lifted position once they are lifted prior to main locking.
• the operator is required to lift the bumper and rotate the pre-locking mechanism at the same time in order to lock the bumper at lifted position. This is very difficult and not ergonomic.
• a metal bar located on the bumper is inserted to the slot drilled on the bumper brace to lock the bumper in lifted position.
• a bumper brace with a slot drilled on it will create notch effect during an impact causing the bumper to be deformed easily at that area.
• a literature screening revealed similar applications related to pre-locking systems maintaining rear bumper assemblies on vehicle platforms of trailers, semi-trailers and trucks that are used for road haulage at lifted position once they are lifted prior to main locking.
• Patent with application number TR 2008/06023 relates to a trailer with a sliding and/or lifting roof, towed by a tractor truck to be used for road haulage purposes, incorporating an upper profile attached to vertical profiles, an actuation mechanism attached to a rail located on the upper profile, and a sliding profile attached to the actuation mechanism, an upper bumper connected to the sliding profile by a connection rod, a minimum of one upper lock slot located on the upper bumper at certain intervals and a minimum of one upper lock attached to upper lock slots.
• Utility model bearing application number TR 201 1/1 1920 relates to trailer beds with a sliding and/or lifting roof, towed by a tractor truck to be used for road haulage purposes, incorporating a saddle bumper with lock slots at five different height levels, making it possible to raise or lower the roof of the trailer bed with sliding and/or lifting roof, where the cargo is loaded, at five different positions, a panel connecting the roof to the floor profile during lifting or lowering operations, locking the bumper by positioning the hooks on the lids, eliminating the requirement to replace the struts or the saddle.
• Present invention relates to a pre-locking system maintaining rear bumper assemblies on vehicle platforms of trailers, semi-trailers and trucks that are used for road haulage at lifted position once they are lifted prior to main locking.
• Primary objective of present invention is to make it possible to maintain the bumper at lifted position easily through input by one person only.
• Another objective of present invention is to position the components of the mechanism, that are of vital importance for the functioning of the pre-locking system, at a location where they will be affected less from external factors compared to competition, with a view to ensuring problem-free functioning of the system and protecting it against external factors.
• One other objective of present invention is to make it possible to clean the components of the mechanism of the pre-locking system easily from external factors such as mud, snow or ice.
• a further objective of present invention is to facilitate serviceability of the components of the mechanism of the pre-locking system by minimizing their exposure to impact of factors such as mud or snow.
• Another objective of present invention is to make it easily possible deactivate the lock externally thanks to the simple structure of the pre-locking system.
• a further objective of present invention is to minimize damages sustained by the mechanism of the pre-locking system when the bumper is impacted by installing it not on the bumper arm but elsewhere.
• Present invention is a pre-locking system maintaining rear bumper assemblies on vehicle platforms of trailers, semi-trailers and trucks that are used for road haulage at lifted position once they are lifted prior to main locking, aiming at achieving above mentioned objectives, incorporating a housing bracket secured to the vehicle platform, a lock assembly attached to the housing bracket, locking the rear bumper assembly at lifted position and then releasing it, a lock assembly housing connecting the housing bracket and the lock assembly and enabling the lock assembly to rotate around its axis, a mounting bracket securing the lock assembly housing to the housing bracket and a lock housing spring inside the housing bracket.
• Rear bumper assembly is fitted with a lock striker, engaging to the lock assembly to lock the bumper in order to achieve the objectives of present invention.
• Lock assembly contains a locking jaw engaging to the lock striker to lock the bumper.
• Lock assembly also contains a jaw lever to release the lock striker to unlock the bumper.

• Present invention relates to pre-locking system (A) maintaining rear bumper assemblies (21 ) on vehicle platforms (20) of trailers, semi-trailers and trucks that are used for road haulage at lifted position once they are lifted prior to main locking.
• Diagram-1 depicts a vehicle platform (20) constituting the main body of a trailer that is used for road haulage and carrying the components that form the trailer as well as the cargo.
• Rear bumper assembly(21 ) is attached to the vehicle platform (20).
• Rear bumper assembly (21 ) is fitted with a lock striker (21 .1 ), engaging to the lock assembly (2) to lock the bumper.
• Lock striker (21 .1 ) is either welded to the rear bumper assembly (21 ) or secured detachably by fasteners.
• the pre-locking system (A) constituting the subject of present invention incorporates a housing bracket (1 ) that is secured to the vehicle platform (20), housing the components of the pre-locking system (A).
• Pre-locking system is secured to the vehicle platform detachably, preferably by fasteners, through the mounting holes (1 .1 ) on the housing bracket (1 ).
• the housing bracket (1 ) contains a lock assembly (2), locking the rear bumper assembly (21 ) at lifted position and then releasing it.
• a locking jaw (2.1 ), engaging to the lock striker (21 .1 ) to lock the bumper and a jaw lever (2.2) releasing the locking jaw (2.1 ) to unlock the bumper are located on the lock assembly (2).
• a lock housing spring (3) located inside the housing bracket (1 ), winds the lock assembly (2) to generate the kinematic energy required for locking the bumper.
• a lock assembly housing (4) is provided, connecting the housing bracket (1 ) and the lock assembly (2) and enabling the lock assembly (2) to rotate around its axis.
• a mounting washer (5) and a mounting nut (6) are used as fasteners to secure the lock assembly housing (4) to the housing bracket (1 ).
• the pre-locking system (A) that constitutes the subject of present invention operates as follows based on the information provided in the foregoing.
• the pre-locking system (A) constituting the subject of present invention incorporates a housing bracket (1 ), lock assembly (2), lock housing spring (3), lock assembly housing (4), mounting washer (5) and mounting nut (6).
• the lock assembly (2) is connected to the lock assembly housing (4), mounting washer (5) and mounting nut (6), on the housing bracket (1 ), together with the lock housing spring (3), to form the pre-locking system (A).
