Description

[0001] A CANOPY MOVEMENT SYSTEM

[0002] The present invention relates to the canopy movement mechanism that allows the canopies in aircraft to be opened and closed by sliding and rotating.

[0003] There are canopy movement systems that open by rotating towards the rear, side and front of the aircraft. Said movement directions have their own advantages and disadvantages. Opening the canopy towards the rear of the aircraft is compatible with sliding design in terms of placement and preventing interferences. Sliding designs used in the canopy allow the mechanism to be simpler, lighter and occupy less volume. Opening the canopy towards the front of the aircraft has the advantages of effectively using the volume behind the seat since there will be no mechanism behind the seat, enabling crew escape in emergency situations with the canopy cutting method and allowing the seat to be removed without demounting the canopy. In sliding locking situations, the canopy can be locked in any desired area and the loads acting on the canopy can be easily transferred to the aircraft body. Opening the canopy by rotating allows the canopy to be thrown from the aircraft in emergency situations.

[0004] In the United States patent document numbered US11623730 in the state of the art, a canopy separation system and method for aircraft are mentioned. The aircraft canopy includes a pivot assembly including a first hinge and a second hinge opposite from the first hinge. The first hinge includes a first pivot slot having a first length. The first pivot slot is configured to retain a first aft pin of a fuselage of the aircraft. The second hinge includes a second pivot slot having a second length. The second pivot slot is configured to retain a second aft pin of the fuselage of the aircraft. The first length differs from the second length. The canopy is evacuated from the aircraft in emergency situations and personnel evacuation is performed.

[0005] In the United States patent document numbered US11002054 in the state of the art, a sliding door mechanism is mentioned. The sliding door mechanism includes a track that is fixed in position relative to a door opening, a post fixed in position relative to the track, and a member that is moveable longitudinally with respect to the track. The member being configured to be guided by the track. The mechanism further includes an arm mounted to the member. The arm rotatable about a vertical axis and configured to be pivotably attached to the sliding door. The arm comprises a slot that is configured to receive the post as the door is moved from an open position toward a closed position. The post urges the arm to rotate relative to the carriage, so that the arm transmits a force to the door. The door is moved laterally into the door opening.

[0006] By means of a canopy movement system developed with the present invention, both sliding and rotating movements are provided for canopy movement. Another aim of this invention is to ensure that the lock loads to which the canopy is exposed in the canopy movement system are effectively transferred to the aircraft.

[0007] Another aim of this invention is to provide a compact and relatively simple mechanism design without the need to use complex mechanisms for the canopy movement mechanism.

[0008] Another aim of this invention is to provide a canopy movement mechanism that can be opened towards the front or the rear of the aircraft according to the manufacturer's preference.

[0009] Another aim of this invention is to provide a canopy movement system suitable for use during the routine operation of the aircraft.

[0010] The canopy movement system defined in the first claim and the claims dependent on this claim, which is realised to achieve the aim of the invention, comprises a body that is located on the aircraft. The canopy can be opened and closed so that the pilot can enter and exit the canopy. The canopy load is transferred to the body via the bracket. The canopy has a hinge connected to the canopy and the bracket. The hinge enables the canopy to move by moving on the bracket. The actuator provides the force required for the canopy movement. The fixed end of the actuator is connected to the body and the movable end is directly connected to the canopy structure. The parts of the first bearing element and the second bearing element that are connected to the bracket are fixed, while the other parts can rotate freely around the axis they extend along. The first bearing element and the second bearing element are located at different positions on the bracket and there is a distance between the closest ends of each other, determined by the manufacturer. The first guiding channel and the second guiding channel are located as a channel that will create a recess on the outer surface of the hinge. The first guiding channel slides on the first bearing element, the second guiding channel slides on the second bearing element. The first guiding channel extends almost completely parallel to the direction in which it extends along the length of the aircraft. The sliding channel that is located on the second guiding channel extends almost completely parallel to the direction in which it extends along the length of the aircraft. The transition region is located as a gap at the lower right end of the sliding channel. The vertical force of the actuator ensures that the transition region passes over the second bearing element. The walls of the first guiding channel are located in such a way that they at least partially create a gap between them and the first bearing element. The walls of the second guiding channel are located in such a way that they at least partially create a gap between them and the second bearing element. The first guiding channel and the walls of the sliding channel allow the hinge to only make a sliding movement despite the vertical force applied by the actuator.

[0011] Said canopy movement system comprises a rotation channel. The rotation channel is located on the second guiding channel. The direction in which the rotation channel extends lengthways extends along another direction in such a way that it makes an angle other than zero degrees with the direction in which the sliding channel extends lengthways. The rotation channel is in the form of a channel and extends in a certain curve. The upper end of the rotation channel extends in a way that it has a gap with almost the same cross-sectional area as the transition region. The canopy movement system comprises an open position (III). In the open position (III), the rotation tip almost completely contacts the first bearing element. The first bearing element restricts the degree of freedom of the second bearing element so that the rotation tip cannot slip any further and can only rotate. In the transition position (II) and the open position (III), the hinge can rotate around the rotation tip. In the open position (III), the rotation channel is located on the second bearing element. Between the transition position (II) and the open position (III), the rotation channel moves by sliding on the second bearing element. Only one actuator ensures that the canopy moves between the lock position (I), the transition position (II) and the open position (III).

[0012] In one embodiment of the invention, the canopy movement system comprises an actuator. The actuator is positioned to extend along the guiding angle. The guiding angle is predetermined by the manufacturer according to the canopy opening kinematics. The guiding angle is an angle between the direction in which the sliding channel extends lengthways and the direction in which the actuator extends lengthways, and is different from zero degrees. The fixed end of the actuator is mounted on the body, while its movable end is mounted directly to the canopy structure. The actuator is positioned to extend along the guiding angle. The horizontal component of the net force along the guiding angle of the actuator provides the horizontal force required for the sliding movement of the canopy from the lock position (I) to the transition position (II), while the vertical component of the net force along the guiding angle provides the vertical force for the rotation movement of the canopy from the transition position (II) to the open position (II) and the rotation moment. The distance between the rotation tip position and the position where the actuator applies force to the canopy is the moment arm distance required for rotation. In this way, it is ensured that the canopy moves between the lock position (I), transition position (II) and open position (III) with only one actuator.

[0013] In one embodiment of the invention, the canopy movement system comprises an actuator. The actuator pushes and slides the canopy between the lock position (I) and transition position (II). The actuator pulls the canopy between the transition position (II) and the open position (III) and ensures that it rotates. In this way, the canopy can perform sliding and rotation movements one after another.

[0014] In one embodiment of the invention, the canopy movement system comprises a rotation tip. The rotation tip is located on the first guiding channel, at the end of the first guiding channel closest to the actuator. The rotation tip ensures that the end of the first guiding channel close to the actuator is curved in a radiused form. In this way, in the transition position (II), the rotation tip ensures that the hinge movement slows down with the increasing surface contact with the first bearing element, allows the first bearing element to contact itself and acts as a retarder for the canopy (3) movement. The first locking tip is located on the rotation channel and is located at the lowest end of the rotation channel. The first locking tip, while the canopy is in the open position (III), provides the first bearing element to contact itself by gradually increasing surface contact with the second bearing element and slowing down the hinge movement and acts as a stopper for the canopy. The second locking tip is located at the left end of the sliding channel, which is the farthest end of the sliding channel from the actuator. The second locking tip ensures that the end of the first guiding channel, which is farthest from the actuator, is curved in a radiused form. The second locking tip is almost completely in a radiused form. The second locking tip, in the lock position (I), provides the second bearing element to contact itself by gradually increasing the surface contact with the hinge movement and acts as a stopper for the canopy.

[0015] In one embodiment of the invention, the canopy movement system comprises a bracket and a hinge. The bracket and the hinge are positioned on the body at the front end parts of the canopy in the case where the canopy is desired to open by rotating forward. The front side refers to the nose of the aircraft.

[0016] In one embodiment of the invention, the canopy movement system comprises a bracket and a hinge. The bracket and the hinge are positioned on the body at the rear end parts of the canopy in the case where the canopy is desired to open by rotating backwards. The rear side refers to the exhaust side of the aircraft.

[0017] In one embodiment of the invention, the canopy movement system comprises an actuator. The direction in which the actuator extends lengthways extends in the left downward direction. In this way, the actuator pushes the canopy between the lock position (I) and the transition position (II) and ensures that the canopy slides to the left, and pulls it between the transition position (II) and the open position (III) and ensures that the canopy performs forward rotation movements one after another.

[0018] In one embodiment of the invention, the canopy movement system comprises an actuator. The direction in which the actuator extends lengthways extends in the left upward direction. In this way, the actuator pushes the canopy continuously between the lock position (I), transition position (II) and the open position (III) and ensures that the canopy slides to the left and performs forward rotation movements one after another. In one embodiment of the invention, the canopy movement system comprises a rotation channel. The rotation channel has a curved geometry. Thus, the sliding channel forms a gooseneck form together with the rotation channel. The gooseneck geometry provides the canopy with a wide angle of rotation.

[0019] In one embodiment of the invention, the canopy movement system comprises a pin in the form of a protrusion located on the canopy. There is a slot as a hole located on the body. In the lock position (I), the pin is seated in the slot, thus the canopy is locked, and the lock loads are transferred to the body through the slot. The canopy slides from the lock position (I) in which the canopy is locked to the transition position (II) in which the pin has no contact with the slot and comes out of the slot. The actuator provides the force required for the pin and the slot to move between the lock position (I) and the transition position (II).

[0020] In one embodiment of the invention, the canopy movement system comprises a transition tip. The transition tip connects the outer wall of the upper part of the sliding channel and the outer wall of the rotation channel at the end close to the transition region. The rotation channel is in a form that will create a smooth surface transition together with the sliding channel and the transition region.

[0021] In one embodiment of the invention, the canopy movement system comprises a transition tip. The transition tip connects the sliding channel outer wall and the rotation channel outer wall with a curved form. The transition tip ensures that the second guiding channel transitions smoothly between the lock position (I) and the transition position (II) and / or the transition position (II) and the open position (III) in a way that will cause minimum tension on the second guiding channel.

[0022] In one embodiment of the invention, the canopy movement system comprises at least two alignment protrusions. The alignment protrusions are located on the hinge. Alignment protrusions are protrusions extending down from the hinge and positioned opposite each other. The canopy movement system comprises a centering element. The centering element is located in the gap between the alignment protrusions facing each other.

[0023] There is some gap between the centering element and the alignment protrusions. The centering element can rotate freely around the axis along which it extends. In case the canopy starts to move out of alignment while moving between the lock position (I), transition position (II) and open position (III), only one of the ends of the centering element facing the alignment protrusions contacts the alignment protrusion approaching it and ensures that the alignment protrusion and the hinge move in alignment again. In one embodiment of the invention, the canopy movement system comprises an actuator. The direction in which the actuator extends lengthways and the direction angles in which the rotation channel extends lengthways are positioned in a way that they are almost exactly at the same angle radially.

[0024] In one embodiment of the invention, the canopy movement system comprises a mounting opening that is located on the hinge. The mounting opening, the first guiding channel and the second guiding channel are in the form of an I profile when viewed from the front of the hinge, and the gap sections of the I profile form the mounting opening, the first guiding channel and the second guiding channel. The mounting opening extends in a geometry with decreasing cross-sectional dimensions towards the first guiding channel. The mouth section is the last section where the first guiding channel, cross-sectional area of which is constant throughout, has a fixed cross-section, and the cross-sectional area gradually increases from the mouth towards the mounting opening.

[0067] The canopy movement system (1) comprises a body (2) that is located on the aircraft; a canopy

[0068] (3) that is movably located on the body (2) and provides the pilot with access to the cockpit and / or protection of the cockpit; at least one bracket (4) that is located on the body (2) in a way that extends outward from the body (2) and allows the canopy (3) to move thereon; at least one hinge (5) one end of which is connected to the canopy (3) and the other end to the bracket

[0069] (4) and moves together with the canopy (3) on the bracket (4); at least one actuator (6) one end of which is connected to the body (2) and the other end to the canopy (3) and provides the forces that move the canopy (3); a first bearing element (7) that is located on the bracket (4) in a rotatable manner around its own axis and connects the bracket (4) and the hinge (5) to each other; a second bearing element (8) that is located on the bracket (4) with a distance between it and the first bearing element (7) in a way that it can rotate around its own axis, and connects the bracket (4) and the hinge (5) to each other; a first guiding channel (9) in the form of a channel that is located on the hinge (5), extends lengthways and performs a sliding movement on the first bearing element (7) by means of the actuator (6); a second guiding channel (10) in the form of a channel that is located on the hinge (5); a sliding channel (1010) that is located on the second guiding channel (10), extends almost parallel to the direction in which the first guiding channel (9) extends and is movably located on the second bearing element (8); a lock position (I) in which the second bearing element (8) is located within the sliding channel (1010); a rotation tip (910) that is the end of the first guiding channel (9) closest to the canopy (3); a transition region (1020) that is located on the second guiding channel (10) as an opening at the end of the sliding channel (1010) that is farthest from the first guiding channel (9), and allows the second bearing element (8) to exit the sliding channel (1010) while the hinge (5) moves; and a transition position (II) in which the rotation tip (910) almost completely contacts the first bearing element (7), the hinge (5) rotates around the first bearing element (7) and the transition region (1020) passes over the second bearing element (8). (Figure -1 , Figure -2).

[0070] The canopy movement system (1) which is the subject of the invention comprises a rotation channel (1030) that is located on the second guiding channel (10) in the form of a channel, extends in a direction different from the direction in which the sliding channel (1010) extends and one end of which extends in a way to follow the transition region (1020); an open position (III) in which the transition tip (910) is almost completely in contact with the first bearing element

[0071] (7), the hinge (5) rotates about the first bearing element (7) and the second bearing element

[0072] (8) is located within the rotation channel (1030); and the actuator (6) which allows the canopy (3) to move between the lock position (I), the transition position (II) and the open position (III). (Figure - 1 , Figure - 2, Figure - 3, Figure - 4, Figure - 6).

[0073] When the canopy movement system (1) passes from the lock position (I) to the transition position (II), the rotation tip (910) located on the first guiding channel (9) almost completely contacts the first bearing element (7) and enables the rotation tip (910) to rotate around the first bearing element (7). In the lock position (I), the first bearing element (7) can be located anywhere in the first guiding channel (9) according to the manufacturer's preference. In the transition position (II), when the first bearing element (7) contacts the rotation tip (910), the transition region (1020) located as an opening aligns with the second bearing element (8), allowing the transition region (1020) to slide over the second bearing element (8), thus the second bearing element (8) exits the transition region (1020) and the hinge (5) begins to rotate. The first bearing element (7) and the second bearing element (8) are preferably in a wheeled structure that can rotate freely around the direction in which they extend lengthways. (Figure - 1 , Figure - 2).

[0074] In the transition position (II), the transition region (1020) passes over the second bearing element (8), then the second bearing element (8) is placed into the rotation channel (1030). The component of the actuator (6) towards the aircraft body (2) ensures that the rotation channel (1030) passes over the second bearing element (8), thus ensuring that the second bearing element (8) is placed into the rotation channel (1030) in a controlled manner. The rotation channel (1030) ensures that the hinge (5) rotates around the first bearing element (7) in a controlled manner, enabling the canopy (3) to rotate and open according to the canopy (3) rotation kinematics previously determined by the manufacturer. The system enables the routine operational use of the canopy (3), which allows the pilot to access and exit the canopy (3) in routine use. (Figure - 1 , Figure - 2, Figure -3, Figure - 4, Figure - 6).

[0075] In one embodiment of the invention, the canopy movement system (1) comprises a guiding angle (11) which is the angle between the direction in which the sliding channel (1010) extends and the direction in which the actuator (6) extends, as determined by the manufacturer, and an actuator (6), one end of which is fixed to the body (2) and the other end of which is movably connected to the canopy (3), is positioned to extend along the guiding angle (11), thus allowing the canopy (3) to switch between the lock position (I), the transition position (II) and the open position (III). The horizontal component of the force components of the actuator (6) along the guiding angle (11) enables the first guiding channel (9) and the sliding channel (1010) to slide on the first bearing element (7) and the second bearing element (8) between the lock position (I) and the transition position (II). When the second bearing element (8) is engaged in the transition region (1020) in the lock position (I), the vertical component of the force components of the actuator (6) along the guiding angle (11) extending from the aircraft floor to the canopy (3) causes the transition region (1020) to slide over the second bearing element (8), thus in the transition position (II) the hinge (5) begins to rotate around the rotation tip (910). Between the transition position (II) and the open position (III), the vertical component of the force components of the actuator (6) along the guiding angle (11) extending from the aircraft floor to the canopy (3) causes the rotation channel (1030) to slide over the second bearing element (8), thus enabling the canopy (3) to both slide and rotate with only one actuator (6) without the need for complex mechanisms. (Figure - 4, Figure -12, Figure -13). In one embodiment of the invention, the canopy movement system (1) comprises an actuator (6) that pushes the canopy (3) between the lock position (I) and the transition position (II), pulls the canopy (3) between the transition position (II) and the open position (III), thus enabling the canopy (3) to perform consecutive sliding and rotating movements. The actuator (6) pushes the canopy (3) between the lock position (I) and the transition position (II) parallel to the direction in which the aircraft extends, thus the lock is lifted and the canopy (3) becomes ready to rotate. In the embodiment where the actuator (6) pulls the canopy (3) between the transition position (II) and the open position (III), the rotational moment that enables the canopy (3) to rotate around the rotation tip (910) is obtained, and the canopy (3) rotates outwards and opens. In embodiments in which the actuator (6) is positioned to extend partially towards the first guiding channel (9) and partially towards the body (2), pulling the canopy (3) between the transition position (II) and the open position (III) ensures that the rotational moment in the correct direction is obtained. (Figure -1 , Figure - 2, Figure - 3, Figure -12, Figure - 14).

[0076] In an embodiment of the invention, the canopy movement system (1) comprises the rotation tip (910), that is almost completely arc-shaped, is located on the first guiding channel (9) and acts as a stopper for the canopy (3) by gradually bringing it into contact with the first bearing element (7); a first locking tip (1040) that is almost completely arc-shaped, is the end of the rotation channel (1030) farthest from the canopy (3) and acts as a stopper for the canopy (3) by gradually ensuring contact with the second bearing element (8) in the open position (III); and a second locking tip (1050) that is almost completely arc-shaped, is the end of the sliding channel (1010) farthest from the canopy (3) and acts as a stopper for the canopy (3) by gradually ensuring contact with the second bearing element (8) in the lock position (I). The geometry in the form of a spring ensures that the stresses to which the hinge (5) will be exposed are gradually realised over time when the first bearing element (7) touches the rotation tip (910) in the transition position (II) and the second bearing element (8) touches the first locking tip (1040) in the open position (III). In this way, the hinge (5) can operate for a longer structural life. (Figure - 6).

[0077] In one embodiment of the invention, the canopy movement system (1) comprises a bracket (4) and a hinge (5) positioned on the aircraft nose side of the canopy (3) by the manufacturer, allowing the canopy (3) to rotate forward and open by means of the actuator (6). In embodiments in which the manufacturer wants the canopy (3) to rotate forward and open, the bracket (4), hinge (5), actuator (6), first bearing element (7), second bearing element (8), first guiding channel (9) and second guiding channel (10) are positioned on the aircraft nose side of the canopy (3). (Figure -12, Figure -13). In one embodiment of the invention, the canopy movement system (1) comprises a bracket (4) and a hinge (5) positioned by the manufacturer on the aircraft exhaust side of the canopy (3), allowing the canopy (3) to rotate and open backwards by means of the actuator (6). In embodiments where the manufacturer wants the canopy (3) to rotate and open backwards, the bracket (4), hinge (5), actuator (6), first bearing element (7), second bearing element (8), first guiding channel (9) and second guiding channel (10) are positioned on the aircraft exhaust side of the canopy (3). (Figure -14, Figure -15).

[0078] In one embodiment of the invention, the canopy movement system (1) comprises an actuator (6) that extends partially towards the body (2) and partially towards the first guiding channel (9), pushing the canopy (3) between the lock position (I) and the transition position (II), and pulling it between the transition position (II) and the open position (III), thereby enabling the canopy (3) to perform sliding and rotating movements consecutively. The guiding angle (11) at which the actuator (6) extends radially is determined between 180°-270° in degrees, according to the preference of the manufacturer, so that the angle differences between the direction in which the actuator (6) extends and the direction in which the first guiding channel (9) extends are a value that is different than zero degrees. Thus, the two force components required for both sliding and rotating the canopy (3) are obtained. (Figure -12, Figure -14).

[0079] In one embodiment of the invention, the canopy movement system (1) comprises an actuator (6) that extends partially towards the canopy (3) and partially towards the first guiding channel (9) lengthways, thus pushing the canopy (3) between the lock position (I), transition position (II) and open position (III) and enabling the canopy (3) to perform sliding and rotating movements consecutively. The guiding angle (11) at which the actuator (6) extends radially is determined between 90°-180° in degrees, according to the preference of the manufacturer, so that the angle differences between the direction in which the actuator (6) extends and the direction in which the first guiding channel (9) extends are a value that is different than zero degrees. In this way, the two force components required for both sliding and rotating the canopy (3) are obtained. (Figure -13, Figure -15).

[0080] In one embodiment of the invention, the canopy movement system (1) comprises a rotation channel (1030) that forms a gooseneck shape together with the sliding channel (1010), allowing the canopy (3) to rotate at a wide angle. (Figure - 6).

[0081] In an embodiment of the invention, the canopy movement system (1) comprises at least one pin (12) that is positioned on the canopy (3) in the form of a protrusion; at least one slot (13) that is located as a cavity on the body (2); lock position (I) in which the canopy (3) is locked by the pin (12) entering the slot (13); the transition position (II) in which the canopy (3) moves from the lock position (I) by making a sliding movement, the pin (12) comes out of the slot (13) in a way that there is a distance between it and the slot (13), and the second locking tip (1050) is at a distance from the second bearing element (8); and the actuator (6) that allows the pin (12) to move between the lock position (I) and the transition position (II). The sliding movement between the lock position (I) and the transition position (II) enables the lock to be opened or the open canopy to be locked. (Figure - 7, Figure - 8).

[0082] In an embodiment of the invention, the canopy movement system (1) comprises a transition tip (1060) which is the end of the sliding channel (1010) close to the canopy (3), and a rotation channel (1030) having a smooth surface transition geometry together with the sliding channel (1010) and the transition region (1020). The parts of the sliding channel (1010), the transition region (1020) and the rotation channel (1030) which are close to each other do not contain any sharp corners, thus ensuring that the transition of the second guiding channel (10) from the lock position (I) to the transition position (II) and from the open position (III) to the transition position (II) is carried out regularly and smoothly. (Figure - 6).

[0083] In one embodiment of the invention, the canopy movement system (1) comprises a transition tip (1060) that has a radiused form between the outer wall of the sliding channel (1010) and the rotation channel (1030), and enables the second guiding channel (10) to make a smooth transition between the lock position (I) and the transition position (II) and / or the transition position (II) and the open position (III). The transition tip (1060) contacts the second bearing element (8) from its outer wall. Thus, the transition of the second guiding channel (10) from the lock position (I) to the transition position (II) and from the open position (III) to the transition position (II) is ensured to be carried out regularly and smoothly. (Figure - 6).

[0084] In an embodiment of the invention, the canopy movement system (1) comprises at least two alignment protrusions (14) that are located on the hinge (5), and are extensions facing each other from the hinge (5) to the body (2); and a centering element (15) that is located on the bracket (4) between the alignment protrusions (14), rotates around its own axis, and has at most one surface contact with the alignment protrusions (14) between the lock position (I), the transition position (II) and the open position (III), thus ensuring the aligned movement of the canopy (3) between the lock position (I), the transition position (II) and the open position (III) when the canopy (3) moves between the lock position (I), transition position (II) and open position (III), if the canopy (3) wobbles in one direction relative to the direction it extends lengthways, the centering element (15) compensates for the wobble by contacting the alignment protrusions from the other direction and ensures that the canopy (3) moves in alignment. The centering element preferably has a wheel-like structure that can rotate freely around the axis it extends lengthways. (Figure - 9). In one embodiment of the invention, the canopy movement system (1) comprises an actuator (6) that is located along the extension that is almost parallel to the extension along which the rotation channel (1030) extends. The actuator (6) contributes to the moment required for the rotation movement of the canopy (3) and to the regular occurrence of the rotation movement. (Figure - 12, Figure -14).

[0085] In an embodiment of the invention, the canopy movement system (1) comprises a mounting opening (920) in the form of a channel with a width predetermined by the manufacturer at the end of the hinge (5) that is furthest from the canopy (3) and narrows towards the first guiding channel (9), and a mouth (930) on the side of the first guiding channel (9) facing the mounting opening (920), which is the end where the first guiding channel (9) that extends along the length starts to widen. The mounting opening (920) allows the first guiding channel (9) to be mounted to the first bearing element (8). The widening form of the mouth (930) contributes to easy mounting. (Figure - 6).
