Description

[0001] A DOOR LOCK MECHANISM

[0002] This invention relates to a locking mechanism suitable for use on a door of an air vehicle.

[0003] Usage of light-weight locking mechanisms on doors is an important issue in aviation. In air vehicle sliding door systems, when external or internal locking system is requested, the mechanism to lock the system first moves along a movement axis of the door, which then moves perpendicular to the movement axis of the door and completes the locking process. In similar lock systems, direct hook type lock systems are mostly preferred. However, the reliability of such systems is low (the ability of the system to hold on to its slot) and the risk of injury to the user increases. There is a need to develop a lightweight and effective lock system suitable for aviation structures.

[0004] JPH11350814, which is included in the known-state of the art, discloses a lock mechanism for vehicle doors. Said mechanism comprises a lock device to simplify the connection of a rotary handle and a switch handle. The device has a base plate with a horizontal wall and a vertical wall, a body fixed to the horizontal wall, a rotary handle positioned on the vertical wall, and a switch handle located in the slot in the actuator that can rotate freely on the vertical wall.

[0005] US2011173891 , which is included in the known-state of the art, discloses a device and a system comprising a release device configured to unlock a sliding door panel from the left and right sides of the sliding door panel. Left and right sides of the sliding door panel are opposite in the sliding direction.

[0006] GB393180, which is included in the known-state of the art, discloses a lock mechanism for sliding doors. Said mechanism has a lever-shaped handle with a horizontal pivot. When the lever is pulled to open the door, one end of the lever carries an arm of the hinged latch and the vertical pivot of the latch is released from its slot. The face of the latch is concentric with the pivot. The mechanism also comprises a plate with a recess configured solely for the insertion of the latch. US2020239119, which is included in the known-state of the art, discloses a door assembly for an air vehicle. Said door assembly comprises a passenger door, a fuselage section for locating the passenger door, and a survival cradle lock bar for releasing the survival cradle. The passenger door can move between a raised position and a lowered position relative to the fuselage section. The survival cradle lock bar is connected to the passenger door and / or the machine body section via a coupling device. The coupling device comprises a locking mechanism to trigger the gripping device fixed to the fuselage section of the aircraft together with the pre-positioned survival cradle. In this way, a latch of the survival cradle is detachably attached to the gripping device.

[0007] US11299250, which is included in the known-state of the art, discloses a door arrangement relative to the flight deck door of an aircraft. There is a latch on the edge of the door, which is arranged to engage the latch recess when it is in the closed position within the door frame. The access door can be rotated forward from the closed position to the open position. It discloses a first mechanical door handle system with a mechanical combination lock, and a door lock mechanism positioned on the rear side of the privacy door and combined with the latch.

[0008] Thanks to a door lock mechanism according to the present invention, a more durable and more reliable door lock system is provided.

[0009] Another object of the present invention is to provide a lightweight door lock system for an air vehicle.

[0010] Another object of the present invention is to lock a door in a practical, effective and easy way.

[0011] The door lock mechanism realized to achieve the object of the invention, which is defined in the first claim and other claims dependent thereon, comprises a body of an air and / or space vehicle; at least one door on the body that allows access to the inside of the body by opening and closing; at least one handle that is removably mounted on the door and enables the opening, closing and locking movements of the door; a rod positioned on the door to move linearly in line with the axis passing through the point where it is connected to the door, wherein the rod can be triggered by the user thanks to the handle and move in the direction it extends; a slot located on the axis where the rod extends, into which the rod is removably placed; a first position (I) in which the rod is not located in the slot and the user can open the door; a second position (II) in which the door cannot be opened, the rod is almost completely inserted into the slot and the movement of the door is prevented.

[0012] The door lock mechanism according to the invention comprises a lock bearing with a channeled structure. The handle moves on the lock bearing by sliding. The spring is compressed by the user applying pressure on the handle towards the door and pressing the handle towards the door. When the spring is compressed, the spring and the handle move by sliding on the lock bearing. The handle, which is in the first position (I), slides on the lock bearing with the compressed spring and comes to the second position (II). There is a housing in which the spring is located. One side / end of the housing is connected to the rod, the other side / end is connected to the lock bearing. There is at least one extension extending outward from the lock bearing. The extension at least partially contacts the handle when in the first position (I) and / or the second position (II), preventing removal of the handle from the lock bearing. Individual extensions are available for the handle in the first position (I) and the handle in the second position (II).

[0013] In an embodiment of the invention, the door lock mechanism comprises the spring that is pressed against the door by the user to store energy by compression. The lock bearing is triggered by the simultaneous movement of the handle and the rod in the direction that the rod extends, as the spring moves downwards in the handle, which is released from the extensions by compression. The handle is slid between the first position and the second position on the lock bearing.

[0014] In an embodiment of the invention, the door lock mechanism comprises alignment of lateral surfaces of the handle and the lock bearing almost completely side by side, so that when the user presses the handle, it can be freed from the extensions and slide on the lock bearing.

[0015] In an embodiment of the invention, the door lock mechanism comprises simultaneous movement of the rod and the housing that moves on the lock bearing with a spring therein. In an embodiment of the invention, the door lock mechanism comprises the handle that is closer to the slot in the first position (I) than in the second position (II). When the handle moves from the first position (I) to the second position (II), it moves away from the slot.

[0016] In an embodiment of the invention, the door lock mechanism comprises the housing with approximately the same surface area as the lock bearing.

[0017] In an embodiment of the invention, the door lock mechanism comprises a handle suitable for use on sliding doors.

[0018] In an embodiment of the invention, in case of sliding doors, the door lock mechanism comprises a rail mechanism with one side on the body and the other side on the door, facing each other, in order to trigger and slide the door by a user and / or a servo motor (Figure 1).

[0019] In an embodiment of the invention, the door lock mechanism comprises an extension that extends linearly on the lock bearing, allowing the spring compressed by the handle in the first position to move to the same form until it reaches the second position.

[0020] In an embodiment of the invention, the door lock mechanism comprises extensions in the form of tabs located on the lock bearing when the handle is in the first position and the second position.

[0021] In an embodiment of the invention, the door lock mechanism comprises L-shaped extensions that prevent the handle from moving when the spring is in the free position.

[0022] In an embodiment of the invention, the door lock mechanism comprises extensions in eccentric flanged form that gradually limit the movement of the handle in the first position and / or the second position. The extensions that are higher in the first position and the second position are located lower in the transition zone between the first position and the second position.

[0023] In an embodiment of the invention, in case of sliding doors, the door lock mechanism comprises triggering and sliding the door by a user and / or an electric motor. The door lock mechanism realized to achieve the object of the present invention is illustrated in the attached drawings, in which:

[0044] The door lock mechanism (1) comprises at least one body (G) on an air and / or space vehicle; at least one door (2) on the body (G); at least one handle (3) on the door (2), which allows the door (2) to move; at least one rod (4) located on the door (2) in connection with the handle (3), triggered by the handle (3) and thus moving in the direction it extends; at least one slot (5) located as a groove on the body (G), allowing the handle (3) to be inserted or removed therein; the handle (3), which has a first position (I) allowing movement of the door (2) when the rod (4) is completely removed from the slot (5); the rod (4) which is at least partially inserted into the slot (5); the handle (3) with a second position (II) in which the movement of the door (2) is restricted thanks to the contact of the rod (4) with the wall of the slot (5).

[0045] The door lock mechanism (1) according to the invention comprises at least one lock bearing (6) on the door (2), which allows the handle (3) to slide by means of its channeled structure; at least one spring (7), which is compressed when the user applies a pressure force via the handle (3), so that the spring (7) is slid by the user, allowing the handle (3) to move between the first position (I) and the second position (II); at least one housing (8) located on the lock bearing (6), in connection with the rod (4), and allowing the spring (7) to be contained therein; at least one extension (9) extending outwards from the lock bearing (6), so that the spring (7) at least partially contacts the handle (3) in the first position (I) and / or the second position (II) and that the handle (3) is held on the lock bearing (6).

[0046] It comprises at least one door (2) on a body (G), i.e. an air vehicle, that can be opened or closed to provide access to the interior of the air vehicle and / or the body (G). In order to lock the door (2) and to open and close it, there is at least one handle (3) on the door (2) that moves through the center where it is connected to the door (2). There is at least one rod (4) in the door (2), which can be moved by the handle (3) and triggered by the handle (3) along its length outwards from the door (2). There is at least one slot (5) inside the body (G) for inserting the rod (4) removably, which is located opposite the rod (4) in the direction that the rod (4) moves. There is a second position (II) in which the rod (4) is located outside the slot (5) and the door (2) can be moved freely by the user. There is a first position (I) in which the pin (4) is almost completely inserted into the slot (5), preventing the door (2) from moving. Thanks to the handle (3), the door (2) can be moved between the second position (II) and the first position (I) (Figure - 2).

[0047] The door lock mechanism (1) allows the handle (3) to move by sliding within the lock bearing (6), thanks to the lock bearing (6) with a channeled structure. By applying a pressure force on the handle (3) by the user, the spring (7) is compressed such that the handle (3) is slid and moved by the user, between the first position (I) and the second position (II). It provides a base for the protection and compression of the spring (7), thanks to the housing (8) located on the lock bearing (6) and moving in connection with the rod (4). Thanks to the extensions (9) extending out from the lock bearing (6), the spring (7) contacts the handle (3) at least partially in the first position (I) and / or second position (II) and holds the handle (3) on the lock bearing (6) (Figure - 3 and Figure - 4).

[0048] In an embodiment of the invention, the door lock mechanism (1) comprises the spring (7), which is compressed when the handle (3) is pressed by the user; the handle (3), which is released from the extensions (9) when the spring (7) is compressed; the lock bearing (6) triggered by the linear movement of the handle (3) and the movement of the rod (4) in the direction it extends, thus allowing the handle (3) to slide and move between the first position (I) and the second position (II). Therefore, the handle (3) triggered by the user and the rod (4) are enabled to move in a linear direction almost simultaneously (Figure - 5 and Figure - 6).

[0049] In an embodiment of the invention, the door lock mechanism (1) comprises the handle (3) and the lock bearing (6) that almost completely overlap surface to surface when a pressure force is applied on the handle (3). Thus, the handle (3) is enabled to slide easily on the lock bearing (6) without getting stuck on the extensions (9).

[0050] In an embodiment of the invention, the door lock mechanism (1) comprises the housing (8), with one surface connected to the rod (4) and one surface connected to the lock bearing (6), wherein the housing (8) moves on the same axis as the rod (4) and surrounds the spring (7). Therefore, the rod (4), housing (8) and handle (3) that triggers the spring

[0051] (7) inside the housing (8) can move synchronously in the same direction.

[0052] In an embodiment of the invention, the door lock mechanism (1) comprises the first position (I) in which the handle (3) is closer to the slot (5); the second position (II) in which the handle (3) is positioned further from the slot (5) than the first position (I). The handle (3) is closer to the slot (5) in the first position (I) than in the second position (II). When the handle (3) moves from the first position (I) to the second position (II), it is allowed to move away from the slot (5).

[0053] In an embodiment of the invention, the door lock mechanism (1) comprises the housing

[0054] (8) that almost completely surrounds the lock bearing (6). Since the housing (8) and lock bearing (6) have almost the same surface area and located in connection with each other, there is no need for the housing (8) to move with the movement of the handle (3).

[0055] In an embodiment of the invention, the door lock mechanism (1) comprises the handle (3) suitable for use on sliding doors (2). The handle (3) can be used on hinged doors (2) and sliding doors (2).

Thanks to the rail mechanism (10), the handle (3) can be used in sliding doors (Figure 1).

[0057] In an embodiment of the invention, the door lock mechanism (1) comprises the spring (7) on the lock bearing (6), which maintains its form throughout the extension (9); the extension (9) that holds the handle (4) in the first position (I) and the second position (II) in a form compatible manner with itself; the extension (9) that enables the spring (8) to remain in the compressed form so that the handle (4) can move between the first position

[0058] (I) and the second position (II). In this way, the spring (7), which is compressed by the handle (3) in the first position (I), is enabled to move in the same form until it reaches the second position (II).

[0059] In an embodiment of the invention, the door lock mechanism (1) comprises a plurality of extensions (9) in the form of tabs, which, for the first position (I) and the second position

[0060] (II), enable the handle (3) to almost completely hold on to the lock bearing (6) when the spring (7) is in the free position. Thanks to the tab-shaped extensions (9), the handle (3) is effectively held on the lock bearing (6).

[0061] In an embodiment of the invention, the door lock mechanism (1) comprises extensions (9) that are almost completely L-shaped, thus enabling the handle (3) to hold on to the lock bearing (6) when the spring (7) is in the free position. Thanks to the L-shaped extensions (9), the handle (3) is effectively held on the lock bearing (6). In an embodiment of the invention, the door lock mechanism (1) comprises extensions (9) that have almost completely an eccentric flanged form, thus gradually restricting the movement of the handle (3) in the first position (I) and / or the second position (II). Thanks to the extensions (9) in eccentric flanged form, the handle (3) can hold on to the lock bearing (6) effectively and gradually.

[0062] In an embodiment of the invention, the door lock mechanism (1) comprises the handle (3) to which a force is applied towards the door (2) by the electric motor or user and / or which is slid on the lock bearing (6). In this way, the opening and closing of the door (2) is achieved with a force.
