Description

1 / 10 PEDAL ADJUSTMENT SYSTEM

[0001] The present invention relates to an adjustment mechanism for pedals used in aircraft.

[0002] During flight, pedals located in aircraft are used by pilots to control the control surfaces in the aircraft. It is important for pilots to easily access the pedals in the aircraft cockpit during flight. Pedal adjustment systems are used to provide forward / backward movement of the pedals used in aircraft relative to the pilot's position. Such systems enable pilots to easily and quickly adjust the position of the pedals relative to the pilot without changing the position in which they are seated.

[0003] United States patent document US20150259065, which is included in the known state of the art, discloses a system for retaining pedal mechanisms used in helicopters in a desired position. In this system, it is disclosed that pilots have to pull the pins at this point when leaning or extending their hand towards the pedals so that the pedals are placed in an appropriate position relative to the pilots.

[0004] United States patent document US20100126298, which is included in the known state of the art, discloses an arm with a screw that is used to move pedals forward / backward. Pedals are moved by turning the screw by means of a handle / grip attached to the end of this arm.

[0005] Thanks to the test system according to the present invention, an easy, practical adjustment system, Petition 870220055229, dated 06 / 24 / 2022, p. 15 / 37 2 / 10 effective, efficient and reliable is achieved by using human resources to adjust pedals in aerial vehicles in relation to the pilot's position.

[0006] Another objective of the present invention is to enable this pedal adjustment system in aerial vehicles to have less weight and occupy less space.

[0007] Another objective of the present invention is to prevent the use of an electric motor or an element activated by an external energy source in order to perform the position adjustment of pedals in aerial vehicles, so that it is performed only mechanically.

[0008] The pedal adjustment system embodied to achieve the object of the invention and defined in the first claim and the other dependent claims thereof comprises a floor located in aircraft; a body located on the floor; an arm extending from the body to its full length and located in such a way that it is movable back and forth in the direction in which it extends; a spring located in the body that allows the arm to move by storing energy with the compression or tension that it accumulates; a pin located in the body and having a locked position (I) that allows compression or tension force to be stored in the spring when contacting the arm, and a released position (II) in which contact of the pin with the arm is eliminated when the pin is activated by the pilot and the arm moves in the direction in which it extends;a first chamber serving as a support and in which the arm is movably located along the geometric axis in which it extends between the arm and the body; a second chamber that is located between the pin; Petition 870220055229, dated 06 / 24 / 2022, page 16 / 37 3 / 10 and the body and in which the pin is located in a movable manner when the pin is activated by the pilot; and at least one pedal (P) that is located in such a way that it can be moved further away and closer in the direction of the pilot when activated by the arm movement while the pin is in the released position (II), in which the pedal is enabled to be locked when the pin is released when the position desired by the pilot is obtained.

[0009] The pedal adjustment system of the invention comprises a guide that is located on the body, extends almost perpendicularly from the body to the arm, and prevents the arm from rotating around its own geometric axis when contacting the arm, preferably having a cylindrical shape.

[0010] In one embodiment of the invention, the pedal adjustment system comprises a guide that is fixed to the body and extends from the body to the arm; a channel in the body, which contains the guide. By means of the guide extending from the body to the arm, the arm is positioned in such a way that it cannot rotate around its own geometric axis.

[0011] In one embodiment of the invention, the pedal adjustment system comprises an arm that is movably located in the first chamber and is positioned in such a way that it is almost perpendicular to the pin that is movably located in the first chamber.

[0012] In one embodiment of the invention, the pedal adjustment system comprises a pin spring located in the first chamber that limits the movement of the pin in the first chamber by applying force to the pin when the pin Petition 870220055229, dated 06 / 24 / 2022, p. 17 / 37 4 / 10 is in the released position (II), and allows the pin to change to the locked position (I) by means of the force it applies to the pin when the pin is released by the pilot. Thus, the pin spring enables the pin to contact the arm in a more effective way.

[0013] In one embodiment of the invention, the pedal adjustment system comprises a first chamber located in such a way that it is fixed to the body in a removable manner by the manufacturer. Thus, if the first chamber is deformed, it is replaced by a new chamber by the manufacturer.

[0014] In one embodiment of the invention, the pedal adjustment system comprises a segment that is located in the first chamber in order to prevent the first chamber from disengaging from the body.

[0015] In one embodiment of the invention, the pedal adjustment system comprises a protrusion located on the pin that limits the movement of the pin when it contacts the first chamber when the pin is in the released position (II). Therefore, when it comes into contact with the first chamber, the protrusion prevents the pin spring from becoming stuck or fully opening when the pin is moved to the released position (II) by the pilot.

[0016] In one embodiment of the invention, the pedal adjustment system comprises a second chamber mounted on the body by means of a tight-fitting method. Thus, the second chamber is located in such a way that it can be easily attached and removed by the manufacturer in case of deformation.

[0017] In one embodiment of the invention, the pedal adjustment system comprises a second chamber that has a Petition 870220055229, dated 06 / 24 / 2022, page 18 / 37 5 / 10 almost completely cylindrical shape with a flanged structure such that it extends outward from the body.

[0024] All parts illustrated in the figures are individually designated with a reference number, and the corresponding terms for those numbers are listed below: 1. Pedal adjustment system. Body. Arm. 4. Spring 5. Pin 6. First chamber 7. Second Chamber 8. Guide Petition 870220055229, dated 06 / 24 / 2022, page 19 / 37 6 / 10 9. Channel 10. Pin spring 11. Segment 12. Protrusion 13. Flange (Z) Floor (P) Pedal (I) Locked position (II) Released position

[0025] The pedal adjustment system (1) comprises a floor (Z) located in aircraft; a body (2) located on the floor (Z); an arm (3) extending from the body (2) to its full length and located in such a way that it is movable in the body (2); at least one spring (4) located in the arm (3) that allows the arm (3) to be activated with the energy stored therein; a pin (5) located in the body (2) having a locked position (I) that allows energy to be stored in the spring (4) contacting the arm (3), and a released position (II) in which contact of the pin (5) with the arm (3) is eliminated when the pin (5) is activated by the pilot and the arm (3) is allowed to move in the direction in which it extends; a first chamber (6) in which the pin (5) is located in a movable manner when the pin (5) located in the body (2) is in the released position (II); a second chamber (7) located in the body (2) and in which the arm (3) is located in such a way that it is movable in the body (2);and at least one pedal (P) activated by the movement of the arm (3) when the pin (5) is in the released position (II) (Figure 1).;

[0026] The pedal adjustment system (1) of the invention Petition 870220055229, dated 06 / 24 / 2022, page 20 / 37 7 / 10 comprises a guide (8) that is located in the body (2), extends from the body (2) to the arm (3) and prevents the arm (3) from rotating around its own geometric axis when contacting the arm (3) (Figure 2).

[0027] The pin (5) contacts the arm (3) and allows the pin (5) to be moved to the locked position (I). With the pin (5) in the locked position (I), the spring (4) is located in the body (2) in a stretched mode. The pin (5) is pulled and activated by the pilot so that it is moved to the released position (II). With the pin (5) in the released position (II), the arm (3) moves in the direction in which it extends with the force of the spring (4). The pedal (P), which is in contact with the arm (3), moves closer to the pilot by the movement of the arm (3). When the pedal (P) is pushed by the pilot to a desired position relative to the pilot, the pin (5) is moved to the locked position (I). Thus, the pedal (P) is moved to the desired position relative to the pilot's preference. There is a first chamber (6) in the body (2), in which the pin (5) is located in a movable manner. The pin (5) moves within the first chamber (6) while passing from the locked position (I) to the released position (II).There is a second chamber (7) in the body (2), in which the arm (3) is located in a movable manner in the direction in which it extends (Figure 3).

[0028] The guide (8) located in the body (2) and extending outward from the body (2) prevents the arm (3) from rotating around its own geometric axis when contacting the arm (3), preferably having an almost completely cylindrical shape. Thus, the arm (3), which is almost perpendicular to the pin (5), does not rotate around the axis. Petition 870220055229, dated 06 / 24 / 2022, page 21 / 37 8 / 10 geometric in which it extends, allowing the pin (5) to change to the locked position (I) when it comes into contact with the pin (5).

[0029] In one embodiment of the invention, the pedal adjustment system (1) comprises a channel (9) extending into the arm (3) almost to its full length; a guide (8) located in the channel (9) so as not to impede movement of the arm (3). The guide (8) is fixedly located in the body (2). The guide (8) extending from the body (2) into the channel (9) prevents the arm (3) from rotating around its geometric axis when contacting the channel (9) (Figure 4).

[0030] In one embodiment of the invention, the pedal adjustment system (1) comprises an arm (3) located in the second chamber (7) such that it is almost perpendicular to the pin (5) located in the first chamber (6). Thus, when the pin (5) is in the locked position (I), it contacts the arm (3) more effectively.

[0031] In one embodiment of the invention, the pedal adjustment system (1) comprises a pin spring (10) located in the first chamber (6) which limits the movement of the pin (5) in the first chamber (6) by applying force to the pin (5) when the pin (5) is in the released position (II), and allows the pin (5) to change to the locked position (I) when the pin (5) is released by the pilot. Thus, the pin (5) can contact the arm (3) more effectively by means of the force of the pin spring (10).

[0032] In one embodiment of the invention, the pedal adjustment system (1) comprises a first chamber (6) removablely attached to the body (2). Thus, in the event that the first chamber (6) is deformed, it can be Petition 870220055229, dated 06 / 24 / 2022, p. 22 / 37 9 / 10 replaced with a new camera by the manufacturer.

[0033] In one embodiment of the invention, the pedal adjustment system (1) comprises a segment (11) located in the first chamber (6) such that it prevents the first chamber (6) from losing contact with the body (2). Thus, the first chamber (6), which is removablely attached to the body (2), is forced out of the body (2) by the pressure of the pin spring (10) while the pin (5) is in the released position (II), and the first chamber (6) contacts the segment (11) such that it remains inside the body (2) (Figure 5).

[0034] In one embodiment of the invention, the pedal adjustment system (1) comprises a segment (11) that is removablely attached to the first chamber (6). Thus, if the segment (11) is deformed, it is replaced by a new segment by the manufacturer.

[0035] In one embodiment of the invention, the pedal adjustment system (1) comprises a protrusion (12) located on the pin (5), extending outward from the pin (5) and limiting the movement of the pin (5) by contacting the first chamber (6) when the pin (5) is in the released position (II). When the pin (5) is in the released position (II), the protrusion (12) contacts the first chamber (6) and almost completely prevents the pin spring (10) from becoming stuck. Thus, it enables the fatigue life of the pin spring (10) to be extended.

[0036] In one embodiment of the invention, the pedal adjustment system (1) comprises a second chamber (7) which is removablely attached to the body (2) by means of a tight-fitting method. Thus, if the second chamber (7) is Petition 870220055229, dated 06 / 24 / 2022, p. 23 / 37 If the inner tube is 10 / 10 deformed, it is replaced with a new one by the manufacturer.

[0037] In one embodiment of the invention, the pedal adjustment system (1) comprises a second cylindrical chamber (7) having a flange (13) extending outward from the body (2). Thus, the flange (13) located on the second chamber (7) allows the second chamber (7) to be easily attached to or removed from the body (2) (Figure 6).
