DETAILED DESCRIPTION OF THE INVENTION
[0038] In this detailed description, the subject matter locking mechanism (1) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
[0039] In FIG. 1, a representative perspective view of the assembled form of the subject matter locking mechanism (1) is given. The present invention relates to a locking mechanism (1) which provides additional force providing fixation of the sliding door in open position in a safe manner when the vehicle is positioned in an inclined position (II) and providing fixing/closing of the sliding door in open position with less force and in an easier manner when the vehicle is positioned in a flat position (I). In said locking mechanism (1), there is a primary damping mechanism (10) and an additional damping mechanism (30).
[0040] On said primary damping mechanism (10), there is a gripper (15) where a pin (60), provided on the sliding door, is connected. Said gripper (15) is connected onto a movable body (14). As can be seen in FIG. 2, there is a primary rail (12) and a piston (13) on said movable body (14). The movable body (14) is connected to a cover (20) in order to protect the inner section of the primary damping mechanism (10) from dust, dirt and similar items. A stopper (11) is connected to the end part of said cover in order to stop the movement of the pin (60), provided on the sliding door, after connection thereof to the gripper (15).
[0041] In FIG. 3, a representative frontal cross sectional view of the assembled form of the subject matter locking mechanism (1) is given. There is a secondary body (31) in said additional damping mechanism (30) configured to slide with respect to the cover (20) and to be able to displace at least partially. A secondary compression extension (33) is provided on said secondary body (31). At least one secondary spring (34) is positioned between a primary compression extension (21), provided on the side of the cover (20) facing the additional damping mechanism (30), and said second compression extension. There is at least one movement cocoon (19) provided mutually on the movable body (14) and the additional damping mechanism (30) and there is at least one delimiting extension (32) extending into said movement cocoon (19) through the additional damping mechanism (30). Thanks to said delimiting extension (32), the movement of the additional damping mechanism (30), which can displace with respect to the cover (60), is delimited. There is at least one primary wall (17) and a secondary wall (18) provided on the side of the movable body (14) facing the additional damping mechanism (30). A lock housing (16) is provided such that there is a predetermined distance between said primary wall (17) and said secondary wall (18).
[0042] In the additional damping mechanism (30), there is a drive arm (43) which can rotate at a first pin (41) axis and provided on one side of said first pin (41) and there is a control element (40) having a control arm (44) provided on the other side thereof. On said control arm (44), there is a secondary housing (46) provided on the side which is close to the first pin (41) and there is a primary housing (45) provided at the end side of the control arm (44). There is a protrusion part (47) between said secondary housing (46) and said primary housing (45). In the additional damping mechanism (30), on the surface provided against the control arm (44), there is a movement surface (35) in a manner providing inclination. A ball (36) is positioned between said movement surface (35) and said control arm (44). The inclination height in the movement surface (35) decreases towards the primary housing (45) and it provides positioning of said ball (36) inside the primary housing (45) under normal conditions depending on gravity. In the control element (40), moreover, there is at least one primary press spring (42) which forces the control element (40) to rotate at the first pin (41) axis and which compresses the ball (36) inside the primary housing (45) or inside the secondary housing (46).
[0043] In the additional damping mechanism (30), there is a locking element (50) which can rotate at a second pin (51) axis and having a lock arm (53) which extends towards the drive arm (43) vicinity of the second pin (51). At the locking element (50), there is at least one secondary press spring (52) which provides rotation of the lock arm (53) at the second pin (51) axis.
[0044] In FIGS. 4 and 5, the representative upper and lateral cross sectional views of the subject matter locking mechanism (1) where the sliding door is in closed position and where the vehicle is stopped in inclined position (II) are given. When the vehicle stops in inclined position (II) and when the sliding door is in closed position, the ball (36), provided in the additional damping mechanism (30), is positioned in the primary housing (45). As can be seen in FIGS. 6 and 7, when the sliding door advances at an opening direction (III), the pin (60) provided on the sliding door engages into the gripper (15) and pushes the movable body (14) in the stopper (11) direction. In this case, the secondary wall (18), provided on the movable body (14), pushes the lock arm (53), provided in the additional damping mechanism (30), towards the drive arm (43). As the drive arm (43) is pushed, the ball (36) positioned in the primary housing (45) in the control arm (44) is released and the ball (36) is positioned inside the secondary housing (46) after sliding on the movement surface (35) as a result of gravity effect in this case. When the ball (36) arrives in the secondary housing (46), since the primary housing (45) is empty, the drive arm (43) begins pushing the lock arm (53).
[0045] In FIGS. 8 and 9, the representative upper and lateral cross sectional views of the subject matter locking mechanism (1) where the sliding door passes to closing position and where the vehicle is stopped in inclined position (II) are given. When the sliding door advances at a closing direction (IV), the movable body (14) moves in the closing direction (IV). By means of the movement of the movable body (14) in the closing direction (IV), the lock arm (53), pushed by the drive arm (43), enters into the lock housing (16) provided between the primary wall (17) and the secondary wall (18). The secondary spring (34) is activated as the lock arm (53) enters into the lock housing (16). As can be seen in FIG. 11, in this case, the secondary compression extension (33), provided in the secondary body (31), compresses the secondary spring (34) and the additional damping mechanism (30) begins advancing in the closing direction (IV). The additional damping mechanism (30) can move along the width of the movement cocoon (19). Thus, in the inclined position (II), the closing resistance of the door is increased.
[0046] The return of the additional damping mechanism (30) back to the prior position is provided in the case where the closed door again passes to open position. As the sliding door is opened, the movable body (14) advances in the opening direction (III) and the secondary wall (18) again pushes the lock arm (53) onto the drive arm (43). In this case, the ball (36) is released and it can move on the movement surface (35) thanks to the effect of gravity.
[0047] In FIGS. 12 and 13, the representative top and lateral cross sectional views of the subject matter locking mechanism (1) where the sliding door is in closed position and where the vehicle is stopped in flat position (I) are given. While the vehicle is in flat position (I), when the sliding door is in closed position, the ball (36) is positioned on the primary housing (45). As can be seen in FIG. 15, when the sliding door moves in the opening direction (III), the pin (60) enters into the gripper (15) and provides the movable body (14) to advance in the opening direction (III). As the movable body (14) advances in the opening direction (III), the secondary wall (18) pushes the lock arm (53) and the lock arm (53) exerts pressure to the drive arm (43). As the drive arm (43) is pushed by the lock arm (53), the control arm (44) moves upwardly. In this case, since the vehicle is in flat position (I), the ball (36) continues to stay in the primary housing (45).
[0048] In FIGS. 16 and 17, the representative upper and lateral cross sectional views of the subject matter locking mechanism (1) where the sliding door is in closed position again and where the vehicle is stopped in flat position (I) are given. In case the sliding door moves in the closing direction (IV), the primary spring (12) is compressed by means of the piston (13) and the movable body (14) moves in the closing direction (IV). During the movement of the movable body (14) in the closing direction (IV), since the ball (36) is positioned in the primary housing (45), the control arm (44) cannot move. Since the control arm (44) cannot move, the drive arm (43) does not push the lock arm (53). Therefore, in case the vehicle is in flat position (I), the additional damping mechanism (30) is not active.
[0049] Thus, a locking mechanism (1) having an additional damping mechanism (30) is provided which is active and which increases the fixation resistance of the sliding door in the open position in case the vehicle is positioned at an inclined position (II) and which is deactivated in case the vehicle is positioned in flat position (I).

It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
