ARTICULATION MECHANISM

FIELD OF THE INVENTION [001] The present invention relates to an articulation mechanism that allows the opening and closing of the doors of household appliances.

BACKGROUND OF THE INVENTION [002] In appliances that have door frames such as refrigerators, ovens and freezers; articulation mechanisms that allow the doors to be coupled to the body of the device, and allow them to be opened and closed around an axis that crosses said edges. In addition to having sufficient strength to load bodies of appliances that have doors of different weights, the articulation systems comprise counterweight spring systems in order to provide convenience to the user while lifting the door. Additionally, articulation systems are presented to which a damper is added in order to prevent the door from slamming against the body while closing the door.

[003] United States patent document number US8533914 in the foundations of the invention reveals an articulation for the doors of home appliances. Articulation, spring that controls and smooths the movement of the door, and damping system are presented. The damper intervenes when the door is about to be closed and

provides a smooth closing. [004] 0 template document in german utility number DE20306043 in the fundamentals gives invention reveals an articulation for the doors From appliances such as

refrigerators and freezers. Articulation is presented,

2/14 spring that controls and smooths the movement of the door, and damping system. The damper intervenes when the door is about to be closed and provides a smooth closing.

[005] United States patent document number US8806718 on the foundations of the invention reveals an articulation for the doors of household appliances. The joint comprises a damper for the purpose of improving the movement of the door.

[006] Damping systems that are present in the state of the art may not provide different force absorptions at different door positions in relation to the appliance. These situations cause insufficiencies in providing the desired comfort while closing the door.

[007] In damping systems that are present in the state of the art, important parts such as spring and damper are placed outside the body of the joint and, for this reason, are exposed to external effects. The system that is exposed to impacts, dirt and dust loses its function over time.

[008] In the state of the art, the forces that are transmitted to the damper do not reach perpendicularly to all positions of the door. This situation causes the shock absorber to become deformed over time due to the lateral forces that appear on the shock absorber.

[009] The articulation systems cannot remain in the assembly position before being assembled, due to the spring they contain. For proper assembly, the joint must be kept in the mounting position and must be secured in place in some way. In United States patent document number US6438799

3/14 which is present in the state of the art, a plastic part is developed to fix the joint in the assembly position which is broken in the first use after assembly. As a result of this part being broken, it becomes useless if the joint is disassembled and reassembled. At the same time, broken parts pose a risk to the mechanism and the breaking process requires high forces to be exerted. A locking system must be developed which allows the joint to be disassembled and assembled multiple times, which does not cause a breakage event, which does not thereby jeopardize the mechanism, which does not require high forces to be exerted, such as those necessary in the process breaking.

BRIEF DESCRIPTION OF THE INVENTION [010] The aim of the invention is to provide a hinge mechanism comprising a damper within the hinge in order to avoid accelerations during closing.

[011] Another objective of the invention is to provide an articulation mechanism that provides the movement to be transmitted to the damper with the help of a meat form, and that provides different closing facilities for the meat that is produced in the desired forms.

[012] Another objective of the invention is to provide a hinge mechanism that comprises a locking mechanism that keeps the mechanism fixed in the mounting position in order to allow mounting multiple times.
