[0032] The examples and related conditions detailed herein are primarily intended to assist the reader in understanding the principles of the present application and are not intended to limit its scope to these specific examples and conditions. It is clear that those skilled in the art would be able to design various arrangements which, although not explicitly described or depicted herein, embody the principles of the present application and are included within its spirit and scope.

[0033] Furthermore, to help with such understanding, the following description can describe slightly simplified embodiments of the application. As will be apparent to those skilled in the art, other embodiments of the application can be more complex.

[0034] In some cases, modified examples of the application can also be described. This is only to help with the understanding and likewise not to limit the scope or establish limitations of the application. These modifications do not constitute an exhaustive list and other modifications can be made by those skilled in the art while remaining within the framework of the application.

[0035] Furthermore, all statements herein regarding the principles, aspects and embodiments of the application, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. This is intended to cover any and all equivalents which can be developed now or in the future.

[0036] As can be seen in the attached figures, the object of the application is a hinge 1 intended to equip a door of a fixed device 2, for example an electrical cabinet of an aircraft or a hatch of an aircraft.

[0037] The hinge 1 comprises a first part 3, called mobile part, intended to be mounted on a door 4 of the fixed device 2 and a second part 5, called fixed part, intended to be mounted on a box 6 of the fixed device 2.

[0038] To simplify the reading of this specification, an orthogonal coordinate system (X, Y, Z) is depicted in the attached figures. The direction Z corresponds to the pivoting axis of the door 6, which is preferably but not limitatively chosen to be vertical. The directions X and Y are orthogonal to the direction Z, the direction X being in the plane of the door.

[0039] The mobile part 3 and the fixed part 5 each comprise at least one hinge part. Preferably but not limitatively, one of the mobile part 3 and the fixed part 5 comprises one more hinge part than the other of the fixed part 5 and the mobile part 3. In other words, in one embodiment, the mobile part 3 comprises N hinge parts and the fixed part 5 comprises N+1 hinge parts. In another embodiment, the fixed part 5 comprises N hinge parts and the mobile part 3 comprises N+1 hinge parts. In the embodiment depicted here, the mobile part 3 comprises three hinge parts and the fixed part 5 comprises two hinge parts.

[0040] The hinge portions of the mobile part 3 and of the fixed part 5 are shaped to cooperate with each other, the hinge portions of the mobile part 3 moving between the two hinge portions of the fixed part 5, so that the cable C can be inserted into the hinge 1 and held in place in the direction Z, as will be described in detail later.

[0041] The mobile part 3 is described in detail next.

[0042] As can be seen in the figures, the mobile part 3 comprises a body 10, for example a molded plastic body, extending between a first end 11 and a second end 12.

[0043] The body 10 widens from the thin and curved first end 11 to the wider end 12. Between the ends 11, 12, the body 10 is delimited by pairs of opposite outer surfaces S1, S2, S3 and S4, each extending between the first end 11 and the second end 12.

[0044] The surface S1 is substantially planar and is pierced by two orifices 13. The surface S1 is designed to be pressed against the door 4. The surfaces S3 and S4 have a trapezoidal overall shape.

[0045] The body 10 comprises a cavity 14 constituted by a recess on the surface S2, and the bottom 15 of which constitutes a plate 16 for fixing the mobile part 3 to the door 4. The plate 16 comprises two orifices 13 for receiving screws fastening the hinge 1 to the door 4.

[0046] The end 12 carries the hinge portion 7 of the mobile part 3. In the embodiment depicted here and in a non-limiting manner, the mobile part comprises three hinge portions 17, 18 and 19, respectively called lower hinge portion, upper hinge portion and intermediate hinge portion.

[0047] The hinge portions 17, 18 and 19 have the overall shape of a hollow and laterally open cylinder, as will be described in detail later. The cylinder of the hinge portions 17, 18, 19 is coaxial with an axis A-3 parallel to the direction Z. Thus, the cable C can be inserted into the hinge portions along the axis Z and retained in the hinge 1.

[0048] As has been indicated, the lower hinge portion 17 is a tongue in the overall shape of a hollow and laterally open cylinder and is delimited by a planar outer wall 20. The lower hinge portion 17 comprises a first portion 21, called base portion, which is mounted above in the direction Z with a second portion 22, called inner portion. The first portion 21 extends between a first end 23 of the tongue and a second end 24 facing, thus defining an opening angle a of the tongue 17, for example between 20° and 45°.

[0049] The internal portion 22 has a greater opening angle than the base portion 21, which defines a shoulder E in the outer wall 20 in the direction Z. In the plane (X, Y), the base portion 21 has a greater thickness than the internal portion 22, which defines a step M between the base portion 21 and the internal portion 22. The step M is joined to the shoulder E along a rectilinear edge.

[0050] In other words, the lower hinge portion 17 comprises two coaxial C-shapes positioned one above the other, formed by the base portion 21 and the internal portion 22, the C-shape of the internal portion 22 being smaller than the C-shape of the base portion 21, that is to say thinner and with a wider opening than the C-shape of the base portion.

[0051] The upper hinge portion 18 is symmetrical to the lower hinge portion with respect to the plane (X, Y).

[0052] As already indicated, the upper hinge portion 18 is a tongue having the overall shape of a hollow and laterally open cylinder and is defined by a planar outer wall 25. The upper hinge portion 18 comprises a first portion 26, called base portion, below which a second portion 27, called internal portion, is located in the direction Z. The base portion 26 extends between a first end 28 of the tongue and a second end 29 facing, defining a given opening angle, for example between 20° and 45°. In the embodiment depicted here, the opening angle a of the base portion 26 is the same as that of the base portion 21 of the lower tongue 17.

[0053] The internal portion 27 has a greater opening angle than the base portion 26, which defines a shoulder E in the outer wall 25 in the direction Z. In the plane (X, Y), the base portion 26 has a greater thickness than the internal portion 27, which defines a step M between the base portion 26 and the internal portion 27. The step M is joined to the shoulder E along a rectilinear edge.

[0054] In other words, the upper hinge portion 18 comprises two C-shapes positioned one above the other, formed by the base portion 26 and the internal portion 27, the C-shape of the internal portion 27 being smaller than the C-shape of the base portion 26, that is to say thinner and with a wider opening than the C-shape of the base portion.

[0055] As already indicated, the intermediate hinge portion 19 is a tongue having the overall shape of a hollow and laterally open cylinder and is defined by a planar outer wall 30. The intermediate hinge portion 19 comprises a portion called base portion 31, which is mounted on both sides in the direction Z with a portion called upper portion 32 and a portion called lower portion 33, the upper portion and the lower portion being symmetrical to each other in the plane (X, Y).

[0056] The base portion 31 extends between the first end 34 of the tongue and the facing second end 35, thereby defining a given opening angle, for example between 20° and 45°. In the embodiment depicted here, the opening angle a of the base portion 31 is the same as the opening angle of the base portion 21 of the lower tongue 17 and of the base portion 26 of the upper tongue 18.

[0057] The opening angle of the upper portion 32 and of the lower portion 33 is greater than the opening angle of the base portion 31, which defines two shoulders E in the outer wall 30 in the direction Z. In the plane (X, Y), the thickness of the base portion 31 is greater than the thickness of each of the upper portion 32 and of the lower portion 33, which defines two steps M, one between the base portion 31 and the upper portion 32 and one between the base portion 31 and the lower portion 33.

[0058] As can be seen in the figures, the distance separating the lower hinge portion 17 from the intermediate hinge portion 18 and the distance separating the intermediate hinge portion 18 from the upper hinge portion 19 are the same. The distances in the direction Z between the end 23 and the end 34, between the end 24 and the end 35, between the end 34 and the end 28 and between the end 35 and the end 29 are denoted respectively hi.

[0059] As can be seen in the figures, the base portions 21, 26 and 31 have the same height in the direction Z and Sint denotes the surface of the hinge portion of the mobile portion 3 defined on one side of the hollow interior space in each of the base portions 21, 26 and 31.

[0060] As can be seen in the figures, the base portions 21, 26 and 31 of the mobile portion 3 have the same internal diameter di. H denotes the distance between the facing lower end and the upper end, i.e. between 23 and 28 and between 24 and 29.

[0061] As can be seen in the figures, the body 10 comprises a joining portion 36 having an E-shaped face, each branch of which connects a portion carrying the plate 16 to one of the tongues 17 to 19.

[0062] The opening angle a defines the angular opening of the mobile portion 3. The internal volume of height H defined by the hollow space between the hinge portions 17 to 19 is the internal volume of the mobile portion 3.

[0063] The fixed portion 5 is described in detail next.

[0064] As can be seen in the figures, the fixed portion 5 comprises a body 40, for example a moulded plastic body, comprising a first portion 41 and a second portion 42.

[0065] The first portion 41 comprises a plate portion 43 for fixing the fixing portion 5 to the box 6. The plate 43 comprises two orifices 44 for the passage of screws. The outer surface S of the carrying plate 43 of the fixing portion 5 is flat so that the fixing portion 5 can be pressed against the box 4.

[0066] The second portion 42 carries the hinge portion 7 of the fixing portion 5. In the embodiment depicted here, the fixing portion comprises, without limitation, two hinge portions 45, 46, respectively called upper hinge portion and lower hinge portion.

[0067] The hinge portions 45 and 46 have the general shape of a hollow and laterally open cylinder, as will be described in detail later. The cylinders of the hinge portions 45, 46 are coaxial and have an axis A-5 parallel to the direction Z. Thus, the cable C can be inserted into the hinge portion along the axis Z and retained in the hinge 1.

[0068] As has been indicated, the upper hinge portion 46 is a tongue having the general shape of a hollow and laterally open cylinder and is delimited by a planar outer wall 47. The wall 47 extends between a first end 48 and a second end 49 facing, thus defining an opening angle of the fixing portion 5. The opening angle β is for example between 20° and 45°. In the embodiment depicted here, the opening angle of the upper hinge portion 45 is the same as the opening angle of the lower hinge portion 45.

[0069] Starting from the center of the cylinder, the upper hinge portion 46 comprises a first laterally open cylinder 50 whose height HI in the direction Z is defined between an outer wall 51 and an inner wall 52 opposite the outer wall 51.

[0070] The upper hinge portion 46 comprises a second laterally open cylinder 53 coaxial with the first cylinder 50. The second cylinder 53 extends between an inner wall coinciding with the inner wall 52 of the first cylinder 50 at a height H2 strictly less than the height HI and an outer wall 54 of variable height. The outer wall 54 corresponds to the outer wall 47 of the hinge portion 46.

[0071] In the two end portions 55, 56 defined between each end 48, 49 of the tongue and a central portion 57, the height of the second cylinder 53 is the height of the first cylinder 50, that is to say HI, and in the central portion 57, the height of the second cylinder 53 is equal to H2. As can be seen in the figures, the hinge portion 46 has an H-shaped cross-section.

[0072] In other words, each of the two shoulders E defines an end portion 55, 56. The thickness of the end portions 55, 56 is strictly less than the thickness of the central portion.

[0073] The inner diameter of the hinge portion 46 is denoted Di. The distance between the facing lower and upper ends, i.e. between 23 and 28 and between 24 and 29, is denoted H’.

[0074] The lower hinge portion 45 is identical to the upper hinge portion 46. Also, for simplicity of the description, identical reference numerals 47 to 57 apply to the lower hinge portion 45.

[0075] The opening angle β defines the angular opening of the fixed portion 5. The opening angle β of the fixed portion 5 is preferably equal to the opening angle a of the movable portion 3.

[0076] The inner volume of height H’ defined by the hollow space between the hinge portions 45 and 46 is the inner volume of the fixed portion 5.

[0077] The dimensions of the hinge portions 17 to 19 of the movable portion 3 and of the hinge portions 45, 46 of the fixed portion 5 are determined so that the hinge 1 functions optimally.

[0078] The height H1 of the first and second cylinders 51, 53 of the hinge portions 45, 46 of the fixed portion 5 is equal to the distance h1 between the end of the lower hinge portion 17 and the end of the intermediate hinge portion 19 and between the end of the intermediate hinge portion 19 and the end of the upper hinge portion 18 of the movable portion 3.

[0079] The diameter di of the base portions 21, 26 and 31 of the movable portion 3 is equal to the diameter Di of the hinge portions 45, 46 of the fixed portion 5. As can be seen in Figure 4 The outer surface of the hinge 1 is thus planar at the location of the cable insertion and extraction.

[0080] The two C-shaped steps M of each hinge portion 17, 18, 19 of the movable portion 3 are equal to the difference between the height H1 and the height H2. Accordingly, to assemble the movable portion 3 onto the fixed portion 5, the portion of the first cylinder 50 of each of the hinge portions 45, 46 protruding from the second cylinder 53 on both sides of the second cylinder 53 having the height H1-H2 can be locked against the steps M of the hinge portions 17 to 19. Accordingly, during use of the door, during rotation of the movable portion 3 relative to the fixed portion 5, the hinge portions 17 to 19 of the movable portion are guided to move in the hinge portions 45, 46 of the fixed portion.

[0081] The assembly of the hinge 1 is next described.

[0082] In a first step, Figure 8A , Figure 9A and Figure 10A), the active part 3 and the fixed part 5 are placed face to face, then the hinge part 46 of the fixed part 5 is inserted between the upper hinge part 19 and the intermediate hinge part 18 of the active part 3, and the hinge part 45 of the fixed part 5 is inserted between the intermediate hinge part 18 and the lower hinge part 17 of the active part 3, until the hinge parts 17 to 19 of the active part 3 are fixed by abutment against the hinge parts 45, 46 of the fixed part 5. Figure 5 , Figure 8B , Figure 9B and Figure 10B ). The axes A-3 and A-5 then coincide, and the hinge parts 17 to 19 are coaxial with the hinge parts 45, 46.

[0083] In this position, the openings of each of the hinge parts 17 to 19 of the active part 3 are aligned with the openings of the hinge parts 45 and 46 of the fixed part 5, which opens the profile Co of the hinge 1 and allows the insertion or extraction of the cable C. This position defines the open position of the hinge 1. In this position, the end portions 23, 34, 28, 24 and 48 are aligned on the one hand with the end portions 35, 34 and 29, 35, 29 and 49 on the other hand.

[0084] The alignment of the openings of the hinge parts of the active part 3 and of the fixed part 5 defines an angular opening OA of the hinge 1, of an angle a. The hollow volume defined by the surface Sint of the active part 3 and by the inner wall 52 of the fixed part 5 defines an internal space Ei of the hinge 1.

[0085] Note that in the hinge 1, the cable C extends along the axes A-3, A-5 of the hinge 1.

[0086] The hinge 1 having been mounted on the fixed device, the active part 3 is then pivoted between two end positions, namely the closed position of the door ( Figure 8D , Figure 9D , Figure 10D and Figure 11 ) and the open (so-called maximum open) position of the door ( Figure 8C , Figure 9C and Figure 10C ), corresponding to a maximum angle of rotation allowed of, for example, 110°.

[0087] Between and at these two end positions, the profile Co of the hinge 1 is closed only by the hinge parts 17 to 19 of the active part 3 or by the hinge parts 45, 46 of the fixed part 5 or by the alignment of the hinge parts 17 to 19, 45, 46 of the active part 3 and of the fixed part 5. Thus, the cable C is retained in the hinge 1 in the closed position of the hinge.

[0088] All these positions correspond to the closed position of the hinge 1.

[0089] In the embodiment depicted here and in the maximum open position (Fig. 1 b), Figure 8C , Figure 9C and Figure 10C , the angular opening of the fixed part 5 and of the mobile part 3 is blocked by the ends of the hinge parts 17 to 19 of the mobile part 3 abutting against the ends of the hinge parts 45, 46 of the fixed part 5, thus closing the profile Co.

[0090] In the closed position, the angular opening of the fixed part 5 and of the mobile part 3 is blocked by the central part of the hinge parts of the opposite part 3, 5, thus closing the profile Co.

[0091] The travel of the hinge parts 17 to 19 of the mobile part 3 is as follows. To pass from the open position of the hinge 1 to the closed position of the hinge in the case where the door is open to the maximum, the hinge parts 17 to 19 are pivoted in the plane (X, Y) by a sufficient angle (a quarter of a turn counterclockwise in the embodiment depicted here) for the ends of the hinge parts 17 to 19 to abut against the ends of the hinge parts 45, 46. Then, to close the door, the hinge is still in the closed position, the hinge parts 17 to 19 are still pivoted in the same direction (a quarter of a turn in the embodiment depicted here). In other words, the travel and the dimensions of the mobile part 3 are such that the hinge parts 17 to 19 move in such a way as to always block the angular opening of the hinge parts 45, 46 of the fixed part 5 in this position of the hinge 1.

[0092] Note that the invention is of course not limited to this counterclockwise rotation direction or to a quarter of a turn.

[0093] In another embodiment, the hinge 1 comprises means 60 for locking the hinge in the closed position.

[0094] In the embodiment depicted here, Figures 12 to 15 the locking means 60 comprise a lug 61 and a bearing surface 62 for the lug 61, the bearing surface being located on one of the hinge parts 45, 46. The bearing surface is a recessed shoulder in the cylindrical body 53 of the upper hinge part 46.

[0095] The locking means 60 comprise actuator means 63 for actuating the lug 61. In the embodiment depicted here, Figures 12 to 15 the actuator means 63 comprise a flexible arm 64 fastened to the lug 61 and activatable by a button 65.

[0096] When the door is in use, the hinge parts 45, 46 of the mobile part are able to pivot between the maximum open position of the door and the closed position of the door, but their travel is blocked by the lug 61 resting against the bearing surface 62 when they exceed the closed position, thus locking the hinge 1 in the closed position.

[0097] When it is desired to open the hinge 1 to insert or extract the cable C, the button 65 is activated, which pulls the lug 61 away from the bearing surface 62 and allows the hinge parts 45, 46 to move to the open position of the hinge 1. In other words, the travel of the hinge parts is increased until the open position of the hinge 1 is reached.

[0098] In a variant not depicted, the actuation means 63 are fixed, for example by an indentation, to receive an accessory such as a screwdriver.

[0099] The hinge 1 according to the second embodiment is identical to the hinge 1 according to the first embodiment, except for the presence of the locking device 60.

[0100] The hinge 1 according to the embodiments of the application can be fitted or removed without having to cut the cable inserted in the hinge. On the contrary, it is only necessary to pull out the cable before removing the hinge 1. The hinge 1 according to the embodiments of the application also makes it possible to modify the wiring of the aircraft without disassembling the hinge, since it is only necessary to open the hinge 1, change the cable and close the hinge 1 again.

[0101] Note that the hinge 1 does not have a physical hinge pin. The action of the hinge 1 is achieved by aligning the hinge parts 17 to 19 of the mobile part 3 with the hinge parts 45, 46 of the fixed part 5.

[0102] Modifications and improvements to the embodiments of the application described above will be obvious to those skilled in the art. In particular, the embodiments and variants described above can be combined with each other, provided they are not incompatible. The above description by way of example is illustrative and not restrictive. The scope of the application is therefore only limited by the scope of the following claims.
