The door lock mechanism (1) comprises a body (G) on an air vehicle; at least one door (2) on the body (G); a locked position (K) in which the door (2) is stationary on the body (G); a free position (S) in which the door (2) is located movably on the body (G); a first handle (3) on the door (2), which allows the door (2) to move from the locked position (K) to the free position (S) or from the free position (S) to the locked position (K); at least one slot (4) on the body (G); a shaft (5) triggered by the first handle (3) and moving in a direction in which the shaft (5) extends on the door (2), wherein the shaft (5) is inserted removably into the slot (4), thus enabling the door (2) to move from the free position (S) to the locked position (K) or from the locked position (K) to the free position (S) (Figure 1 , Figure 2, Figure 3, Figure 8, Figure 9).
The door lock mechanism (1) according to the invention comprises a first rod (6) which transmits a movement of the first handle (3) to the shaft (5); a second handle (7) on the door (2); a second rod (8) which transmits a movement of the second handle (7) to the shaft (5); at least one protrusion (9) which extends outward from each of the first rod (6) and the second rod (8); at least one plate (10) which is located on the shaft (5), with a distance to the protrusions (9) when the door (2) is in the locked position (K), thereby allowing the first handle (3) and second handle (7) to move independently of each other due to said distance, wherein the plate (10) contacts the protrusions (9) when the first rod
(6) or the second rod (8) is triggered, thus enabling the shaft (5) to move so that the door (2) is moved from the locked position (K) to the free position (S) (Figure 4).
The first handle (3) located on the door (2) is triggered by the user, allowing it to move on the door (2). Movement of the handle triggers the shaft (5). When the shaft (5) is triggered, the door is moved to the locked position (K) or to the free position (S) on the body (G).
A second handle (7) is also located on the door (2). The first rod (6) and second rod (8), one end of which can contact the plate (10) and the other end of which can contact the first handle (3) or the second handle (7), are provided to transmit movement of the first handle (3) and the second handle (7) to the shaft (5). Thanks to the distance between the protrusions (9) on the first rod (6) and the second rod (8) and the plate (10) on the shaft (5), the first handle (3) and the second handle (7) can be operated independently of each other, movement is provided. In addition, the door lock mechanism (1) is simplified and made light-weight without using different shafts (5) for the first handle (3) and the second handle (7) and for the first rod (6) and the second rod (8).
In an embodiment of the invention, the door lock mechanism (1) comprises at least one rod arm (11) located in connection with each of the first handle (3) and the second handle
(7), connected rotatably to the door (2), and allowing a movement applied by the first handle (3) or the second handle (7) to be transmitted to the first rod (6) or second rod (8); a first connecting element (12) located between the rod arm (11) and the door (2) and allowing the rod arm (11) to rotate around itself on an axis in which the rod arm (11) is connected to the door (2); at least a second connecting element (13) located between the rod arm (11) and the first handle (3) or second handle (7), and allowing the first handle (3) and/or the second handle (7) to rotate around itself on an axis in which the first handle (3) and/or the second handle (7) is connected to the rod arm (11). Thanks to the first connecting element (12) and the second connecting element (13), the rod arm (11) and the first handle (3) or the second handle (7) can be rotated on the door (2) independently of each other (Figure 5, Figure 6). In an embodiment of the invention, the door lock mechanism (1) comprises a first position (I) of the first handle (3) or second handle (7), in which the first handle (3) or the second handle (7) is triggered by the user to rotate around the first connecting element (12), so that the door (2) is moved from the locked position (K) to the free position (S); a second position (II) in which the surfaces of the first handle (3) or the second handle (7) are rotated almost perpendicularly to a movement direction of the door (2) around the second connecting element (13). Thanks to the first connecting element (12) located on the rod arm (11), the first handle (3) first moves the door (2) to the free position (S), and then the first handle is rotated around the second connecting element (13), so that the first handle (3) or the second handle (7) is moved to the second position (II) in order for the user to open the door (2) in an easier manner (Figure 10, Figure 11).
In an embodiment of the invention, the door lock mechanism (1) comprises at least one torsion spring (14) on the second connecting element (13), which applies a force to the first handle (3) or second handle (7) that are previously moved by the user to the second position (II), so that the first handle (3) or second handle (7) are moved to the first position (I). Thanks to the torsion spring (14), when a user releases the first handle (3) or second handle (7), the first handle (3) or second handle (7) rotates around the second connecting element (13) relative to the rod arm (11), so as to be moved to the first position (I).
In an embodiment of the invention, the door lock mechanism (1) comprises at least one connecting rod (15) located on the rod arm (11), between the rod arm (11) and the first connecting element (12), and transmitting a movement of the rod arm (11) to the first rod (6). Since the connecting rod (15) is connected to the rod arm (11) at a point between the rod arm (11) and the first connecting element (12), movement of the rod arm (11) is transmitted such that the first rod (6) or second rod (8) moves on the door.
In an embodiment of the invention, the door lock mechanism (1) comprises at least one opening (16) on the plate (10), which allows the first rod (6) and the second rod (8) to move relative to the shaft (5) so as to contact the plate (10), wherein the first rod (6) and the second rod (8) are located movably in the opening (16). Thanks to the opening (16) located on the plate (10), the first rod (6) and the second rod (8) can move inside the plate (10) and contact the plate (10) via the protrusions (9), thereby triggering the shaft (5) (Figure 7). In an embodiment of the invention, the door lock mechanism (1) comprises the first handle (3) and the rod arm (11) that correspond to the surface of the door (2) when the door (2) is in the locked position (K). Since the first handle (3) or the second handle (7) is positioned in the body (G) without extending outward from the door, the door (2) does not occupy any extra volume on the air vehicle.
In an embodiment of the invention, the door lock mechanism (1) comprises a third connecting element (17) and a fourth connecting element (18) which enable the connecting rod (15) to be movably connected to the rod arm (11) relative to the first rod (6) or the second rod (8). Therefore, the connecting rod (15) enables the first rod (6) or the second rod (8) to move in a direction desired by the user.
In an embodiment of the invention, the door lock mechanism (1) comprises at least one pin (19) triggered by the shaft (5) so as to be removably inserted into the slot (4), thereby enabling the door (2) to move from the free position (S) to the locked position (K) or from the locked position (K) to the free position (S). Thanks to the pin (19), the door (2) can be securely located in the locked position (K) or in the free position (S).
In an embodiment of the invention, the door lock mechanism (1) comprises the pin (19) located integrally with the shaft (5).
In an embodiment of the invention, the door lock mechanism (1) comprises at least one spring (20) on the pin (19), which applies a pressing force towards the slot (4) when the door (2) is moved from the free position (S) to the locked position (K), thus allowing the pin (19) to be inserted into the slot (4). Thanks to the spring (20), the pin (19) can be automatically moved from the free position (S) to the locked position (K) without requiring any force applied by the user.
In an embodiment of the invention, the door lock mechanism (1) comprises at least one rail mechanism (21) located on the door (2) and allowing the door (2) to be opened and/or closed by the user by sliding. In an embodiment of the invention, the door lock mechanism (1) comprises the door (2) with the first handle (3) on one surface thereof and the second handle (7) on the other surface thereof, mirror-symmetrically to the first handle (3).
