Description

This invention relates to a movement mechanism that enables to move the hooks in the canopies of air and / or space vehicles. In air and / or space vehicles, cockpits are surrounded by transparent structures called canopies. It is thus aimed to isolate noise and meteorological effects, to enhance the visibility and to reduce the friction caused by air flow. By creating a pressurized area within the canopy, it is aimed to protect pilots from atmospheric effects in high-speed flights. Having said this, canopies are considered as a component of pilot rescue systems used to evacuate pilots from air vehicles in emergencies. Canopies are produced from acrylic plastic or polycarbonate materials that require expertise by making transparent shaping in order to provide pilots with a good angle of view. The ability of canopies in providing substantial sealing and their lightweight are important factors affecting the health of pilots and the performance of air vehicles. The opening and closing of the canopies during the access of pilots to the cockpit and the removal (jettison) of canopies from the air vehicle in emergencies are carried out by actuating mechanisms provided on the air vehicle. In addition to canopy actuating mechanisms, various systems that enable pilots to be safely ejected out of the air vehicle are also provided in air vehicles and they need to be operated in line with the actuating mechanisms. While the opening and closing operations of a canopy are performed by a mechanism, the process of locking the canopy onto the air vehicle body to ensure sealing is performed by a different mechanism. While the necessary power is provided to the mechanisms by various motors and actuators, the closed and locked states of a canopy are controlled by means of sensors. Since the use of multiple mechanisms and actuators will increase the area used within the canopy, it leads to the need to larger cockpit volumes and to an increase in the weight of air vehicles. In the Turkish patent document TR202022489, which is included in the known state of the art, it is described that at least one canopy mechanism enables a canopy to move from a closed position to an open position and from the open position to the closed position by performing a rotational motion around an axis that provides the connection of the canopy to the body, and enables the canopy in the closed position to be brought to a locked position by performing a horizontal sliding motion along an axis parallel to the body. In the United States patent document US4375281, which is included in the known state of the art, is described a manually-operable lock comprising a dog mounted in fore-and-aft alignment on the wall of the cockpit of an aircraft and a pair of dog receivers mounted on the canopy for releasably securing a canopy in a closed condition. It comprises a dogactuating arm including internal and external arm components, respectively, supported for oscillation about a common axis and pivotally connected to the dogs through rod. Spring-loaded releasing means mounted on the arm and adapted to be ramp-cammed and positioned in coaxial alignment with a receiving bore when the arm is at the limit of its forward throw enables the arm to be released for releasing the arm for pivotal displacement. In the United States patent document US3145042, which is included in the known state of the art, are described hooks that provide a quick release of cargo hooks. When the cam lever, the cam surface, the hook and the locking pin, the outer end of the cam arm are moved downwardly, the hook grasps the locking pin and pulls the two connector blocks together, and when the outer end cam arm is moved upwardly, the cam surface resting on the pin forces the two connector blocks to separate from each other. Thus, the cam arm and the locking pin perform a dual locking and releasing function. With a canopy movement mechanism developed by this invention, it is ensured that the hook performs a rotational motion by applying force thereon from two different points and the load is distributed to different points on the hook. A further object of the present invention is to develop a more lightweight, compact, reliable and low-cost canopy movement mechanism. The canopy movement mechanism realized to achieve the object of the invention, defined in the first claim and in the claims dependent on this claim, comprises a body, a canopy coupled to the body. Preferably, there are hooks on the body that are symmetrically connected to each other on both sides of the body. The hooks are articulated in a rotatable manner from the part by which they are connected to the body. Preferably, hooks are engaged into the cylindrical and fixed pins located on the canopy. In the open position (A) of the canopy, in which one side of the canopy is close to the cockpit and the other side thereof is rotating away from the cockpit, the cockpit is easily accessible. If the hooks are seated to the pins on the canopy, the canopy assumes the locked position (L). In the locked position (L), the canopy is fixed so that it cannot move on the body. With the edges of the canopy at least partially contacting the body, the canopy assumes a closed position (K) between the open position (A) and the locked position (L). In the closed position (K), the pins are located within the hooks. The movement of the canopy between the open position (A), closed position (K) and locked position (L) is realized by means of at least one actuator. The hooks on the body are rotated around the point where they are hinged to the body by means of the actuator, enabling the canopy to move between the open position (A) and the locked position (L). A rotation guide is provided on the hook so that the hook can grip the pin. The canopy comprised by the canopy movement mechanism of the invention comprises is brought from the locked position (L) to the closed position (K) due to the fact that the hooks can rotate around the point where they are hinged to the body with the triggering of the actuator. With the triggering of the actuator, both sides of the actuator can extend and shorten simultaneously. When the actuator is triggered when the canopy is in the locked position (L), one side thereof can extend and the other side connected to the canopy cannot push the canopy because the hooks are coupled to the pins. A single actuator is provided of which both sides can move. The actuator enables the movement of the canopy between the locked position (L) and the open position (A). Preferably, two separate actuators for rotating the locks of the canopy and moving the canopy away from the cockpit can be located on the canopy to provide the movement of the canopy between the locked position (L) and the open position (A). When the actuator is triggered, it enables the canopy to be brought from the locked position (L) to the closed position (K) by rotating the hooks around the point where they are connected to the body. In the closed position (K) between the open position (A) and the locked position (L) of the canopy in which the pins are positioned within the hooks, the canopy can move at least partially on the body so as to move away from the cockpit. The movement of the canopy on the body in the closed position (K) at least partially away from the cockpit can be realized by extending the other side of the actuator or by triggering the second actuator. While the canopy is brought from the closed position (K) to the open position (A) in which the hooks are freed from the pins, the movement of the canopy away from the cockpit at the same time as the hooks are rotated by the actuator enables the position of the pin to be changed by sliding within the rotation guide. By changing the position of the pin within the rotation guide, the hook is rotated by the pin and the actuator is enabled to rotate the hook from a different point simultaneously. Thus, the hook is rotated by both the actuator and the pin from the closed position (K) of the canopy until the hook is freed from the pin, thus enabling the load to act on the hook from different points. Thus, the hook, which is rotated by forming different moment arms, can be produced from a lower strength material compared to the hook where the force is applied from a single point, and the maintenance and repair cost decreases as the probability of breakage decreases. In an embodiment of the invention, the canopy movement mechanism comprises an inlet mouth that enables the pin to be coupled to the rotation guide while the canopy is brought from the open position (A) to the locked position (L) and the pin to be removed from the rotation guide while the canopy is brought from the locked position (L) to the open position (A). The inlet mouth is in the form that narrows as it extends away from the rotation guide. While the canopy is brought from the closed position (K) to the open position (A), the pin comes from the rotation guide to the inlet mouth. It slows down the rotation of the canopy from the cockpit as it exits the inlet mouth of the pin. In an embodiment of the invention, the canopy movement mechanism comprises a mouth protrusion forming an inlet mouth wall for forming the inlet mouth to narrow as it extends away from the rotation guide. The mouth protrusion is located in the form of a protrusion on the hook and enables the hook inlet mouth to be designed as per user's preference. The mouth protrusion enables the inlet mouth to have the same width as the pin, so that the pin stays opposite the inlet mouth to enter the rotation guide. In an embodiment of the invention, the rotation guide comprised by the canopy movement mechanism has an arc form. There are hooks on the body that are connected to each other in series. By connecting the hooks in series, they are enabled to move simultaneously. Each of the hooks connected in series can rotate around the point where they are hinged to the body by being triggered by the actuator which is of an electromechanical linear actuator type. Based on the symmetry plane of the body, the hooks comprise hooks that are parallel to each other on both sides of the body. The hooks connected in series are located on both sides of the body in parallel to each other and move in a synchronous manner. They enable the canopy to switch between the open position (A) and the locked position (L). A rotation guide is provided on each hook. In an embodiment of the invention, the rotation guide comprised by the canopy movement mechanism is composed of a first guide and a second guide. Due to the rotation of the hook by the actuator when the canopy is in the locked position (L), the pin changes its position in the first guide. The positional change of the pin in the first guide is made possible by rotating the hook when the pin is in a fixed position and by sliding the pin in the first guide. The canopy is thus brought from the locked position (L) to the closed position (K). When the canopy is in the closed position (K), the pin passes from the first guide to the second guide and the canopy can move on the body at least partially away from the cockpit by means of the actuator. While the canopy is brought from the closed position (K) to the open position (A), it slides in the second guide and enables the hook to be rotated simultaneously with the actuator and by applying force thereon from different parts until the pin reaches the inlet mouth with the canopy moving away from the cockpit at least partially. In an embodiment of the invention, the second guide comprised by the canopy movement mechanism is more curved than the first guide. The amount of the curve is user-predetermined and affects the position change speed of the pin in the first guide and the second guide. The pin moves faster on a more curved surface. In an embodiment of the invention, the second guide comprised by the canopy movement mechanism is wider than the first guide. The width affects the amount of movement of the canopy away from the body. Since the canopy does not have the width to be able to move away from the body while the pin is in the first guide, that is, since the first guide and pin have almost the same diameter, the canopy cannot move away from the body. Since the second guide has a larger diameter than the first guide, the maximum amount the canopy can move away from the body corresponds the value found when the diameter of the pin is subtracted from the second diameter. In an embodiment of the invention, the connection element comprised by the canopy movement mechanism restricts the rotation of the hooks by contacting the hooks during the period when the canopy is in the open position (A). The connection element can be triggered by the triggering element and moved back and forth, thus ensuring that it contacts the hook. The triggering element is activated when the triggering pin on the canopy hits the inlet mouth of the triggering element. While the canopy is brought from the locked position (L) to the open position (A), the connection element is pushed by rotating the triggering element by means of the triggering pin and the rotation of the hook is prevented by the contact of the connection element with the hook. It is fixedly located on the body as long as the canopy is in the open position (A). When the triggering element is brought to the inlet mouth from the canopy open position (A), the triggering pin hits the triggering element and enables the triggering element to rotate around the point where it is connected to the body. Meanwhile, the triggering element disconnects the hook and the connection element by pulling the connection element and the hooks begin to move freely. When the contact of the connection element with the hooks is cut off and the hooks are freed, the hooks are rotated by the actuator, so that the canopy comes to the locked position (L) with the actuator rotating the hooks. While the canopy is brought to the locked position (L), the hooks are coupled to the pin, and the triggering element engages the triggering pin and enables the canopy to be fixed to the body. The rotational movement of the triggering element around the point where it is connected to the body is ensured with the triggering pin contacting the triggering element and cutting off the contact of the triggering pin with the triggering element. In an embodiment of the invention, the canopy movement mechanism comprises a stopper provided in the form of a protrusion on the hook and preventing the connection element from contacting and rotating the hook in the open position (A). In an embodiment of the invention, the stopper comprised by the canopy movement mechanism enables the hook to have a conjugate form with the connection element, thereby preventing the hook from rotating in the open position (A). In an embodiment of the invention, the connection element comprised by the canopy movement mechanism sits in the recessed surface formed by the stopper on the hook when the pin comes out of the inlet mouth while the canopy is brought from the locked position (L) to the open position (A). In an embodiment of the invention, the actuator comprised by the canopy movement mechanism is connected to the torque tube. The torque tube is rotatably moved by the actuator along the axis along which it lies on the body. A connection bracket is mounted to both ends of the torque tube. With the rotation of the torque tube, the connection bracket rotates too and pushes or pulls the shaft connected to the other end thereof. With the linear movement of the shaft, the hooks can be rotated around the points where they are connected to the body and coupled to the pins and removed from the pins. With the triggering of the actuator, its end connected to the torque tube extends and rotates the torque tube. When the hooks come out of the pins, the connection bracket contacts the limiter, which is a part on the body, so that the torque tube does not rotate the hooks further and the rotation of the torque tube is prevented. When the hooks come from the closed position (K) to the locked position (L), the limiter provided as a part of the body at least partially prevents the further rotation of the hooks. The connection bracket pulls the hooks by the rotation of the torque tube from the position in which the pins are brought to the inlet mouth of the hooks during which the canopy is brought to the locked position (L), and in this way, it is ensured that the hooks rotate around the axis to which they are connected and engage the pins. However, when the hooks come to the locked position (L), the connection bracket contacts the limiter on the body in order to prevent them from rotating further. A universal joint is provided between the connection bracket and the shaft to prevent the movement occurring while the connection bracket pushes or pulls the shaft from damaging the mechanism. In an embodiment of the invention, the canopy movement mechanism comprises a tensioned spring that enables the triggering element to rotate around the point where it is connected to the body when the contact of the triggering pin with the triggering element is cut off during the movement of the canopy from the locked position (L) to the open position (A). Triggering the triggering element so that it pushes the connection element and the contact of the connection element with the hook is realized with the triggering pin rotating the triggering element as a result of the canopy moving away from the cockpit and with the rotation of the triggering element by means of the spring contacting the triggering element. At the same time, the spring ensures that the instantaneous forces applied to the triggering element when the canopy is in the open position (A) prevent the disconnection of the hook and the connection element. It pushes the connection element by constantly keeping the triggering element in the triggered position. When the triggering pin contacts the triggering element, the continuous force caused by the triggering pin overcomes the triggering force applied by the spring and ensures that the contact of the connection element and the hook is cut off. In an embodiment of the invention, the hook comprised by the canopy movement mechanism is rotated by the actuator for bringing the canopy from the locked position (L) to the closed position (K). With the rotation of the hook, the position of the pin in the first guide is changed and it passes to the second guide when the canopy is in the closed position (K). When the pin is in the second guide while the hooks continue to be rotated from a point by the actuator, the hook can be rotated simultaneously also from other points to which the pin contacts by virtue of the movement of the pin away from the cockpit by means of the canopy. When the canopy is in the closed position (K), it starts to move on the body away from the cockpit. This movement also enables the pin on the canopy to move away from the cockpit and causes the hook to be rotated with the pin applying force from different points than the actuator to rotate the hook along the second guide. When the canopy comes from the closed position (K) to the position in which the pin is located at the inlet mouth, the rotation of the hook is stopped by the triggering element pushing the connection element into contact with the hook. Although the pin has no effect on the rotation of the hook when the pin is at the inlet mouth, the fact that the actuator rotates the hooks can be prevented by the contact of the connection element. It is ensured that the canopy is rotated around the point where it is connected to the body by pushing it away from the cockpit by means of the actuator until the canopy is brought from the closed position (K) to the open position (A). In an embodiment of the invention, the canopy comprised by the canopy movement mechanism is brought from the open position (A) to the closed position (K) by the pull of the actuator. When the triggering pin comes to the inlet mouth of the triggering element while the canopy comes from the open position (A) to the closed position (K), the contact of the hook and the connection element begins to be gradually cut off. However, the setting free the movement of the hooks begins when the pin comes to the inlet mouth of the hook. When the pin comes to the inlet mouth of the hook, the triggering pin is at least partially seated into the triggering element with the canopy approaching the cockpit. While the triggering pin is brought to a position where the triggering element is at least partially seated into it from the inlet mouth, the triggering element rotates around the point where it is connected to the body with the force applied by the triggering pin, gradually pulling the connection element and preventing the contact of the hook with the connection element. Due to the fact that when the pin is brought to the inlet mouth of the hook, the hook is rotated by the actuator and at the same time the canopy is pulled by the actuator towards the cockpit, it is ensured that its position is changed by sliding it along the second guide. Thus, the canopy is brought to the closed position (K). When the pin is brought from the second guide to the first guide, the hooks are rotated by the actuator to bring the canopy to the locked position (L). When the canopy is in the locked position (L), the triggering pin also fully sits into the triggering element and enables the canopy to be fixed onto the body. The canopy movement mechanism realized to achieve the object of the present invention is shown in the accompanying figures, among which; Figure 1 is a schematic representation of the canopy when it is in the locked position (L). Figure 2 is a schematic representation of the canopy when it is in the closed position (K). Figure 3 is a schematic representation of the canopy when it is in the open position (A).

Spring (A) Open Position (K) Closed position (L) Locked position The canopy movement mechanism (1) comprises a body (2), a canopy (3) movably located on the body (2) and enabling access to and / or providing protection to the cockpit, at least one hook (4) located on the body (2), at least one pin (5) located on the canopy (3) and on which the hook (4) can be coupled, a locked position (L) of the canopy (3) in which the hook (4) is coupled to the pin (5) and fixed to the body (2), an open position (A) of the canopy (3) in which the hook (4) is decoupled from the pins (5), a closed position (K) of the canopy (3) between the locked position (L) and the open position (A), at least one actuator (6) enabling the canopy (3) to be moved between the open position (A), the closed position (K) and the locked position (L), wherein the hook (4) rotates around the point where it is connected to the body (2) and moves by means of the actuator (6) while the canopy (3) is brought from the locked position (L) to the open position (A), at least one rotation guide (401) located on the hook (4) and enabling the pin (5) to be coupled to the hook (4). In the closed position (K) of the canopy (3) of the canopy movement mechanism (1) according to the invention, the pin (5) is located in the rotation guide (401) and the canopy (3) can at least partially move on the body (2), wherein the hook (4) is rotated by applying force thereon from different points simultaneously by means of the pin (5) whose position changes within the rotation guide (401) and by means of the actuator (6) which applies force from different points than the pin (5) while the canopy (3) is brought from the closed position (K) to the open position (A) (Figure 1, Figure 2, Figure 3, Figure 4). There is a body (2), which is the air vehicle, and a canopy (3), which is connected to the body (2) and moves relatively to the body (2). The canopy (3) ensures that the pilot is protected and a suitable atmosphere is created during the flight. The hooks (4) rotatably located on the body (2) and the pins (5) fixedly located on the canopy (3) enable the canopy (3) to be locked. In the locked position (L) of the canopy (3), the canopy (3) is almost immovably located on the body (2) and the hooks (4) are coupled to the pins (5). By bringing the canopy (3) from the locked position (L) to the open position (A), it is ensured that the pilot can enter and exit the body (2) and access the cockpit. The canopy (3) has a closed position (K) between the locked position (L) and the open position (A). The actuator (6) is used for the switching the canopy (3) between the locked position (L) and the closed position (K) and for its movement between the closed position (K) and the open position (A). The actuator (6) is located on the canopy (3). By virtue of the actuator (6), it is ensured that the hooks (4) are rotated around the points where they are connected to the body (2) until the canopy (3) and the hooks (4) are freed from the locked position (L) and the pins (5), respectively. A rotation guide (401) is provided on each hook (4) so that the pins (5) can be inserted into the hooks (4). Bringing the canopy (3) from the locked position (L) to the closed position (K), in which the pin (5) is in the rotation guide (401), occurs by rotating the hook (4) by means of the actuator (6). The actuator (6) enables the hook (4) to be rotated around the point where it is connected to the body (2) by pushing the hook (4) until the pin (5) is released from the hook (4). The canopy (3) is fixed on the body (2) until it is brought from the locked position (L) to the closed position (K). When the canopy (3) is brought to the closed position (K) by means of the actuator (6), the actuator (6) pushes the canopy (3) so that the canopy (3) can at least partially move away from the cockpit. With the canopy (3) moving away from the body (2), the pin (5) slides in the rotation guide (401) and starts to rotate the hook (4) at the same time by means of the actuator (6). The hook (4) is enabled to rotate by applying force to the hook (4) from different points by the actuator (6) and the pin (5) until the pin (5) leaves the rotation guide (401). By virtue of rotating the hook (4) by applying force thereon from different points, the load is distributed on the hook (4). In an embodiment of the invention, the canopy movement mechanism (1) comprises at least one inlet mouth (402) that enables the pin (5) to be guided to the rotation guide (401) for the canopy (3) to be brought from the open position (A) to the locked position (L), that narrows as it extends away from the rotation guide (401), thereby enabling to reduce the rotational speed of the canopy (3) while the canopy (3) is brought from the closed position (K) to the open position (A). Thus, while the pin (5) is freed from the inlet mouth (402), the canopy (3) is prevented from being instantly opened and damaged by escaping from the inlet mouth (402). In an embodiment of the invention, the canopy movement mechanism (1) comprises at least one mouth protrusion (4020), which is a protrusion on the hook (4), thereby forming the wall of the inlet mouth (402), enabling the pin (5) and the inlet mouth (402) to remain opposite to each other while the canopy (3) is brought from the open position (A) to the closed position (K) and the inlet mouth (402) to be almost identical in size with the pin (5). By virtue of the mouth protrusion (4020) on the hook (4), which ensures that the width of the inlet mouth (402) is the same as the diameter of the pin (5), it enables the pin (5) and the hook (4) to remain opposite to each other while the canopy (3) is brought from the open position (A) to the closed position (K). Thus, the hooks (4) are securely coupled to the pins (5). At the same time, by virtue of the width being the same, the canopy (3) is prevented from being opened quickly while the pin (5) is freed from the hook (4). In an embodiment of the invention, the rotation guide (401) comprised by the canopy movement mechanism (1) is arc shaped. Thus, it is facilitated to slidingly change the position of the pin (5) in the rotation guide (401) while the hook (4) is rotated and the canopy (3) is moving away from the cockpit (Figure 6). In an embodiment of the invention, the canopy movement mechanism (1) comprises at least one first guide (4011) and at least one second guide (4012), which are part of the rotation guide (401), wherein the hook (4) is rotated around the point where it is connected to the body (2) by means of the actuator (6) while the position of the pin (5) in the first guide (4011) is changed with the rotation of the hook (4), wherein the canopy (3) can be moved at least partially away from the cockpit by means of the actuator (6) when the pin (5) comes from the first guide (4011) to the second guide (4012), wherein the hook (4) is rotated around the point where it is connected to the body (2) simultaneously by the pin (5) of which the position is changing in the second guide (4012) and by the actuator (6) when the canopy (3) starts moving at least partially away from the cockpit. When the pin (5) is switched from the first guide (4011) to the second guide (4012), the canopy (3) is brought to the closed position (K) and the canopy (3) can move at least partially away from the cockpit. The amount by which the canopy (3) moves away from the cockpit with the pin (5) in the second guide (4012) varies depending on the width of the second guide (4012). Thus, when the pin (5) pulls the wall of the second guide (4012) by means of the canopy (3), the rotation of the hook (4) is ensured by applying force from a different point from the actuator (6). By virtue of rotating the hook (4) by applying force thereon from different points, the load on the hook (4) is distributed and the hook (4) is produced from a more compact and less durable material (Figure 7). In an embodiment of the invention, the second guide (4012) comprised by the canopy movement mechanism (1) has a larger arc than that of the first guide (4011). Thus, a space is provided in the second guide (4012) for the movement of the pin (5) and it is ensured that the pin (5) can rotate the hook (4) in addition to the actuator (6) (Figure 7). In an embodiment of the invention, the second guide (4012) comprised by the canopy movement mechanism (1) has a larger width than that of the first guide (4011). Thus, a space is provided in the second guide (4012) for the movement of the pin (5) and it is ensured that the pin (5) can rotate the hook (4) in addition to the actuator (6) (Figure 7). In an embodiment of the invention, the canopy movement mechanism (1) comprises at least one connection element (7) that is located on the body (2) and prevents the hook (4) from being rotated by the actuator (6) by contacting the hook (4) while the canopy (3) is in the open position (A), at least one triggering pin (501) located on the canopy (3), at least one triggering element (8) that is located on the body (2) and can move the connection element (7) closer to the hook (4) and away from the hook (4), wherein the triggering element (8) starts to cut off the contact of the connection element (7) with the hook (4) gradually when the triggering pin (501) contacts the inlet mouth (402) of the triggering element (8) while the canopy (3) is brought from the open position (A) to the closed position (K) by the actuator (6), and enables the canopy (3) to be fixed to the body (2) by being coupled to the triggering pin (501) while the canopy (3) is brought to the locked position (L). By virtue of the connection element (7), the hooks (4) are prevented from moving as long as the canopy (3) is in the open position (A). Thus, the connection element (7) prevents the hooks (4) from rotating while the canopy (3) pulled by the actuator (6) comes from the open position (A) until the pin (5) comes to the inlet mouth (402) of the hook (4), preventing the pins (5) from hitting the tops of the hooks (4) (Figure 5, Figure 6). In an embodiment of the invention, the canopy movement mechanism (1) comprises at least one stopper (9), which is located on the hook (4) so as to make a protrusion thereon, enabling to prevent the rotation of the hooks (4) by contacting the connection element (7) while the canopy (3) is brought from the open position (A) to the closed position (K). During the contact of the connection element (7) with the hook (4) in a way that it is fully seated therein, a recess which is form-fitting to the connection element (7) is formed on the stopper (9) and the hook (4) so that the connection element (7) does not damage the hook (4) (Figure 6). In an embodiment of the invention, the stopper (9) comprised by the canopy movement mechanism (1) enables to form a wall which is form-fitting to the connection element (7) on the hook (4). During the contact of the connection element (7) with the hook (4), a recess which is form-fitting to the connection element (7) is formed on the stopper (9) and the hook (4) to prevent the connection element (7) from damaging the hook (4) (Figure 6). In an embodiment of the invention, the connection element (7) comprised by the canopy movement mechanism (1) sits into the recess formed by the stopper (9) simultaneously when the pin (5) comes out of the inlet mouth (402). Thus, when the contact between the pin (5) and the inlet mouth (402) is cut off, the further rotation of the hooks (4) is prevented by the contact of the connection element (7) with the recess formed by means of the stopper (9) on the hook (4). While the canopy (3) is brought from the open position (A) to the closed position (K), it is ensured that the inlet mouth (402) of the hook (4) remains opposite to the pin (5) and the pin (5) is prevented from hitting to the hook (4) (Figure 6). In an embodiment of the invention, the canopy movement mechanism (1) comprises a torque tube (10) connected to the actuator (6) and circularly actuated by the actuator (6), at least one connection bracket (11), one end of which is connected to the torque tube (10) and rotationally moves with the rotation of the torque tube (10), at least one shaft (12), one end of which is connected to the connection bracket (11) by means of a joint and the other end of which is connected to the hook (4) by means of a joint and enables the hooks (4) to be coupled to the pins (5) or decoupled from the pins (5) by rotating the hooks (4) around the points where they are connected to the body (2) as a result of pushing or pulling the hooks (4) with the rotation of the connection bracket (11). With the torque tube (10) being triggered by the actuator (6), the torque tube (10) is rotated, the connection bracket (11) at the end of the torque tube (10) linearly moves the shaft (12), and the hooks (4) to which the shaft (12) is connected come out of the pins (5) if the shaft (12) pushes them, and are coupled to the pins (5) if the shaft (12) pulls them. In order to couple and decouple the hooks (4) to / from the pins (5) according to the push and pull state of the shaft (12), the hooks (4) are supported by a movable joint on the body (2). Thus, the canopy (3) can be moved between the open position (A) and the locked position (L). A plurality of hooks (4) are provided, which are connected to each other on the body (2) in series, so that when they are pushed or pulled by the shaft (12), they can simultaneously rotate around the points where they are connected on the body (2), respectively. With the simultaneous movement of the hooks (4), the canopy (3) can switch between the locked position (L), closed position (K) and the open position (A) by means of at least one actuator (6), which is an electromechanical linear actuator, and no different mechanisms are required for different hooks (4). Thus, it is ensured that all the hooks (4) can enter and exit the pins (5) at the same time with a more lightweight system. The body (2) comprises more than one hook (4) located parallel to each other on the body (2) according to the axis of symmetry. Thus, the canopy (3) can be fixed to the body (2) in a symmetrical manner. In an embodiment of the invention, the canopy movement mechanism (1) comprises at least one spring (13) that rotates around the point where it is connected to the body (2) so as to make the connection element (7) contact the hook (4) when the contact of the triggering element (8) with the triggering pin (501) is cut off. The triggering of the triggering element (8) can be provided by means of the triggering pin (501) and the tension spring (13). While the canopy (3) moves away from the cockpit and the triggering pin (501) comes out of the triggering element (8), it rotates the triggering element (8) and pushes the L-shaped connection element (7), one end of which is connected to the body (2), from its middle so as to make the other end thereof contact the hook (4). The spring (13), in turn, triggers the triggering element (8) so that it continues to prevent the hook (4) from rotating when a force is instantly applied to the triggering element (8) or the connection element (7) (Figure 8). In an embodiment of the invention, the position of the pin (5) comprised by the canopy movement mechanism (1) is changed in the first guide (4011) by means of the hook (4), which is pushed and rotated by means of the actuator (6) while the canopy (3) is brought from the locked position (L) to the closed position (K), and the hook (4) is rotated by applying force thereon from different points by means of the actuator (6) and the pin (5) whose position is changed in the second guide (4012) with the canopy (3) moving away from the cockpit by means of the actuator (6) by being simultaneously pushed by means of the actuator (6) while the canopy (3) is brought from the closed position (K) to the open position (A). Since the hooks (4) are coupled to the pins (5) while the torque tube (10) is rotated as a result of the partial extension of the end of the actuator (6) connected to the torque tube (10) by triggering the actuator (6) while the canopy (3) is in the locked position (L), the extension of the other end of the same or different actuator (6) that is connected to the canopy (3) is possible so long as the canopy (3) can move away from the body (2). Since the end of the actuator (6) that is connected to the canopy (3) cannot be extended until the canopy (3) is brought from the locked position (L) to the closed position (K) due to the coupling of the hooks (4) to the pins (5), the canopy (3) cannot switch from the closed position (K) to the open position (A). For this reason, the torque tube (10) must rotate and free the hooks (4) from the pins (5). The pin (5) passes from the first guide (4011) to the second guide (4012) with the rotation of the hook (4) by means of the torque tube (10). The release of the hooks (4) from the pins (5) is also ensured by the pin (5) whose position changes within the second guide (4012) due to the fact that the canopy (3) starts to move away from the cockpit at the same time when the canopy (3) is brought to the closed position (K). The hook (4) is rotated by getting supported from both points and it is ensured that the load on the hook (4) is distributed. When the hooks (4) are freed from the pins (5), since the end of the actuator (6) that is connected to the canopy (3) is released, it can extend and open the canopy (3) so as to move it away from the cockpit. However, when the canopy (3) is in the open position (A), it is not desired that the end of the actuator (6) that is connected to the torque tube (10) extends and rotates the torque tube (10) and therefore moves the hooks (4). For this reason, when the hooks (4) are freed from the pins (5), the torque tube (10) is prevented from rotating further with the connection bracket (11) contacting a projection on the body (2) called a limiter. Thus, although the actuator (6) is triggered, since its end connected to the torque tube (10) contacts the limiter, it cannot extend further and cannot rotate the torque tube (10). Due to the fact that the second guide (4012) has a width greater than the cross-section of the pin (5), the canopy (3) can at least partially move away from the cockpit. In an embodiment of the invention, the canopy (3) comprised by the canopy movement mechanism (1) is pulled by the actuator (6) and brought closer to the cockpit while being brought from the open position (A) to the closed position (K), the pin (5) is placed in the inlet mouth (402) of the hook (4) formed by the mouth protrusion (4020) while the canopy (3) is brought from the open position (A) to the closed position (K), the canopy (3) is brought from the open position (A) to the closed position (K) by changing the position of the pin (5) along the second guide (4012) with the canopy (3) moving closer to the cockpit simultaneously with the hook (4) being pulled and rotated by the actuator (6), the pin (5), which is pulled and rotated by the actuator (6) and changes its position along the first guide (4011) while the canopy (3) is brought from the closed position (K) to the open position (A), is seated to the hook (4). While the canopy (3) is brought from the open position (A) to the closed position (K) by being pulled by the actuator (6), the triggering pin (501) contacts the triggering element (8) so that the connection of the connection element (7) with the hook (4) starts to be gradually cut off. By virtue of the connection element (7), when the hooks (4) are desired to be coupled back to the pins (5), they do not need to be rotated so that the hook (4) remains opposite to the pin (5). When the canopy (3) continues to approach the cockpit, the rotation of the triggering pin (501) and the triggering element (8) continues and the triggering pin (501) partially sits into the triggering element (8). Meanwhile, when the pin (5) is seated in the inlet mouth (402), the contact of the connection element (7) with the hook (4) is completely cut off and the hooks (4) are free to rotate. Until the canopy (3) comes to the closed position (K), the hooks (4) are rotated by the actuator (6) and it is ensured that the position of the pin (5) changes within the second guide (4012). Until the canopy (3) comes to the locked position (L), the hooks (4) are rotated by the actuator (6) and it is ensured that the position of the pin (5) changes within the first guide (4011). After bringing the canopy (3) from the closed position (K) to the locked position (L) by means of the actuator (6), a limiter provided as a protrusion of the body (2) limits the rotation of the torque tube (10) by contacting the connection bracket (11). By virtue of the limiter, it is ensured that the hooks (4) are restricted from sitting to the pins (5) by contacting the connection bracket (11) when the canopy (3) comes from 5 the closed position (K) to the locked position (L). The hooks (4) can be seated to the pins (5) up to a desired position according to the position of the limiter. When the pin (5) is advanced along the first guide (4011) in the hook (4), the triggering pin (501) is seated into the triggering element (8). Thus, the hook (4) and the triggering element (8) simultaneously enable the canopy (3) to be fixed to the body (2). 10
