Description

Title of the invention: Support comprising a column and a head connected to the column by a fitting connection system

[0001] The present application relates to a support comprising a column and a head connected to the column by a fitting connection system as well as to an aircraft comprising at least one such support.

[0002] According to an embodiment visible in [Fig.l], a support 10 for connecting a cable 12 (or a bundle of cables) to a structure 14 of an aircraft comprises a column 16, a head 18 as well as a connection system 20 connecting the head 18 and the column 16.

[0003] The column 16 has, at a first end 16.1, a base 22 pressed against the structure 14 and connected to the latter by fixing elements 24 such as rivets or screws for example. This column 16 is substantially cylindrical and has an axis A16 substantially perpendicular to the surface of the structure 14. The column 16 has, at a second end 16.2, an end face 26 substantially perpendicular to the axis A16. The column 16 also comprises a metal tubular insert which has a threaded conduit 28 opening at the end face 26 of the column 16.

[0004] The head 18 comprises a body 30 which has a contact face 30.1 pressed against the end face 26 of the column 16 as well as a system 32 for holding the cable 12, such as two V-shaped branches 32.1, 32.2, connected to the body 30 and configured to receive the cable 12. The latter is held between the branches 32.1, 32.2 by means of a clamping collar 34. According to one embodiment, the head 18 is made of plastic.

[0005] According to one embodiment, the connecting system 20 comprises a screw 36 which passes through the head 18 and is screwed into the threaded conduit 28 of the tubular insert of the column 16. The screw 36 is offset relative to the V-shaped holding system 32, that is to say that the screw 36 is eccentric relative to the branches 32.1, 32.2. This screw 36 is generally made of titanium. The screw 36 must be screwed into the threaded conduit 28 with a calibrated tightening torque so that the head 18 is correctly connected to the column 16.

[0006] This embodiment is not satisfactory because the screw 36 is made of a rare and expensive material. According to another drawback, a support 10 according to the prior art has a relatively large mass due to the fact that the screw 36 is made of titanium and the column 16 is partially metallic. Furthermore, the fact of having to screw the screw 36 with a calibrated tightening torque tends to impact the assembly time. Finally, since the screw 36 can unscrew, it is necessary to use an ovalized nut so as to provide a braking function and hold the screw 36 in position.

[0007] The present invention aims to remedy all or part of the drawbacks of the prior art.

[0008] To this end, the invention relates to a support comprising a column having an end configured to be connected to a structure, a head and a connection system connecting the head and the column, the head comprising a body and a holding system intended to receive an elongated element.

[0009] According to the invention, the connection system comprises: a. a first part integral with a first element among the column and the head, b. a second part secured to a second element, different from the first element, among the column and the head, the second part comprising a housing configured to at least partially house the first part, c. at least one holding system configured to occupy a first state in which the holding system immobilizes the first part in the housing and a second state in which the holding system allows the first part to at least enter the housing.

[0010] This solution makes it possible to reduce the mass of the support compared to the prior art. According to another advantage, the head can be connected to the column without tools and without checking a tightening torque. Finally, it is no longer necessary to check a tightening torque during maintenance operations in order to verify whether the head is still correctly connected to the column.

[0011] According to another characteristic, the first part comprises, from a first end oriented towards the second part, a first section having a first section and a second section having a second section smaller than the first section, the first and second sections being connected by a shoulder. The second part comprises, from a first end oriented towards the first part, a first tubular section having inner and outer lateral surfaces and a bottom, the inner lateral surface and the bottom delimiting the housing, the inner lateral surface having a section substantially identical to the first section of the first section of the first part.Additionally, the holding system comprises at least one stop, positioned protruding relative to the inner lateral surface, configured to be in contact with the shoulder in order to hold the first section of the first part in the housing of the second part.

[0012] According to another characteristic, the holding system deforms elastically between the first and second states, the first state corresponding to a non-elastically deformed state, the second state corresponding to an elastically deformed state.

[0013] According to another characteristic, the first tubular section comprises several slots each extending from the first end over a given length and connecting the inner and outer lateral surfaces, said slots delimiting between them elastically deformable tabs.

[0014] According to another characteristic, the first section of the first part comprises a first cylindrical lateral face. In addition, the inner lateral surface of the first tubular section of the second part is also cylindrical, the first lateral face and the inner lateral surface being configured to immobilize the first and second parts in rotation relative to each other.

[0015] According to another characteristic, the first lateral face and the inner lateral surface respectively comprise first and second grooves configured to fit into each other so as to immobilize the first and second parts in rotation relative to each other.

[0016] According to another characteristic, the connection system comprises a first locking system configured to occupy a locked state in which the first locking system blocks the holding system in the first state and an unlocked state in which the first locking system allows the holding system to pass into the second state.

[0017] According to another characteristic, the first locking system comprises at least one ring configured to slide around the second part between a first position, corresponding to the locked state, in which the ring is close to the first end and a second position, corresponding to the unlocked state, in which the ring is spaced from the first end.

[0018] According to another characteristic, the connection system comprises at least one return element configured to push and hold the ring in the first position corresponding to the locked state.

[0019] According to another characteristic, the connection system comprises a second locking system configured to occupy a first stable state in which the second locking system allows the ring to translate between the first and second positions as well as a second stable state in which the second locking system blocks the ring in the first position corresponding to the locked state.

[0020] According to another characteristic, the first and second parts are secured respectively to the column and to the head, the body of the head comprising a first face oriented towards the column as well as a second face opposite the first face and oriented towards the elongate element in operation. In addition, the second locking system comprises at least one rod extending between first and second ends as well as, for each rod, a conduit opening at the first and second faces and positioned in the extension of the ring, each rod having a length determined so that its second end projects and is spaced from the second face of the body of the head when the ring is in the second position corresponding to the unlocked state and is located at or close to said second surface when the ring is in the first position corresponding to the locked state.

[0021] According to another characteristic, the second locking system comprises first and second rods diametrically opposite relative to the second part as well as a crosspiece connecting the second ends of the first and second rods.

[0022] The invention also relates to an aircraft comprising at least one structure, at least one elongate element and at least one support according to one of the preceding characteristics connecting the elongate element and the structure.

[0037] [Fig. 14] is a side view of a portion of a support equipped with the head visible in [Fig.13],

[0038] According to an embodiment visible in Figures 2 to 9, a support 40, configured to connect an elongate element 42 to a structure 44, comprises a column 46, a head 48 as well as a connection system 50 connecting the head 48 and the column 46.

[0039] The elongate element 42 may be a cable, a cable bundle, a conduit or any other similar element. According to one application, an aircraft comprises at least one support 40 for connecting an elongate element 42, such as a cable or a cable bundle for example, to a structure of the aircraft. Generally, an aircraft comprises a large number of supports distributed along elongate elements.

[0040] The column 46 comprises a first end 46.1 configured to be connected to the structure 44 by a fixing system 52 as well as a second end 46.2 configured to be connected to the head 48. According to one configuration, the fixing system 52 comprises a base 52.1 secured to the first end 46.1 of the column 46 and configured to be pressed against the structure 44 as well as at least one fixing element 52.2, such as a rivet, a bolt or a screw for example, connecting the base 52.1 and the structure 44. Of course, the invention is not limited to this configuration for connecting the fixing system 52 connecting the column 46 to the structure 44.

[0041] According to one arrangement, the column 46 is substantially cylindrical and has an axis A46 substantially perpendicular to the surface of the structure 44. Of course, the invention is not limited to this geometry for the column 46.

[0042] According to one embodiment, the column 46 is made of plastic or composite material. Consequently, it has a mass significantly lower than that of a column of the prior art which incorporates a metal insert.

[0043] The head 48 comprises a body 54 which has a first face 54.1 oriented towards the column 46 and a second face 54.2 opposite the first face 54.1, as well as a holding system 56 intended to receive the elongate element 42. The body 54 and the holding system 56 are configured so that in operation, the second face 54.2 is oriented towards the elongate element 42, the latter being in contact or slightly spaced from said second face 54.2.

[0044] According to a configuration visible in Figures 2 to 9, the holding system 56 comprises at least two V-shaped branches 56.1, 56.2 connected to the body 54 and configured to receive the elongated element 42. The latter is held between the branches 56.1, 56.2 by a link 58, visible in [Fig.3], such as a clamp for example.

[0045] Of course, the invention is not limited to this configuration for the holding system 56 of the elongate element 42. As illustrated in [Fig. 10], the holding system 56 may have a C shape. Generally, the holding system 56 is configured according to the elongate element 42 to be connected to the structure 44.

[0046] According to one embodiment, the head 48 is made of plastic or composite material.

[0047] As illustrated in Figures 5 to 7, the connection system 50 is a nesting connection system comprising: a. a first part 60.1 secured to a first element among the column 46 and the head 48, b. a second part 60.2 secured to a second element, different from the first element, among the column 46 and the head 48, the second part 60.2 comprising a housing 62 configured to at least partially house the first part 60.1, c. at least one holding system 64 configured to occupy a first state in which the holding system 64 immobilizes the first part 60.1 in the housing 62 and a second state in which the holding system 64 allows the first part 60.1 to at least enter the housing 62.

[0048] The connecting system 50 comprises a first locking system 66 configured to occupy a locked state in which the first locking system 66 blocks the holding system 64 in the first state and an unlocked state in which the first locking system 66 allows the holding system 64 to transition into the second state.

[0049] According to one embodiment, the holding system 64 deforms elastically between the first and second states. According to one configuration, the first state corresponds to a non-elastically deformed state and the second state corresponds to an elastically deformed state. Therefore, in the absence of constraints, the holding system 64 is configured to occupy the first state in which it holds the first part 60.1 in the housing 62.

[0050] According to one configuration, the first part 60.1 extends between a first end 68.1 oriented towards the second part 60.2 and a second end 68.2 secured to the first element among the column 46 and the head 48. The first part 60.1 comprises a first section 70 which extends from the first end 68.1 as well as a second section 72 which extends from the first section 70 to the second end 68.2. The first section 70 comprises an end face 70.1 and a first lateral face 70.2 having a first section. The second section 72 has a second lateral face 72.1 having a second section smaller than the first section. Thus, the first part 60.1 comprises a shoulder 74 connecting the first and second lateral faces 70.2, 72.1 of the first and second sections 70, 72. The first section 70 has a height corresponding to the distance separating the first end 68.1 and the shoulder 74. According to one embodiment, the first and second sections 70, 72 (and the first and second lateral faces 70.2, 72.1) are cylindrical and coaxial with a first axis of revolution A60.1. The first end 68.1 is a flat surface perpendicular to the first axis of revolution A60.1. The shoulder 74 is in the form of a crown positioned in a plane perpendicular to the first axis of revolution A60.1.

[0051] According to one configuration, the second part 60.2 extends between a first end 76.1 oriented towards the first part 60.1 and a second end 76.2 secured to the second element among the column 46 and the head 48. The second part 60.2 comprises a first tubular section 78 which extends from the first end 76.1 and has an inner lateral surface 78.1 which delimits the housing 62 and an outer lateral surface 78.2.

[0052] The inner lateral surface 78.1 has a section substantially identical to that of the first section 70 of the first part 60.1.

[0053] According to one embodiment, the inner and outer lateral surfaces 78.1, 78.2 are cylindrical or slightly frustoconical and are coaxial with a second axis of revolution A60.2.

[0054] The first tubular section 78 comprises a bottom 78.3, distant from the first end 76.1, which delimits with the internal lateral surface 78.1 the housing 62. The latter has a depth, corresponding to the distance separating the bottom 78.3 and the first end 76.1, slightly greater than the height of the first section 70 of the first part 60.1. The bottom 78.3 is a flat surface substantially perpendicular to the second axis of revolution A60.2.

[0055] When the first section 70 of the first part 60.1 is inserted into the first tubular section 78 of the second part 60.2, the first and second axes of revolution A60.1, A60.2 coincide. According to one configuration, the first lateral face 70.2 of the first section 70 of the first part 60.1 and the inner lateral surface 78.1 of the first tubular section 78 of the second part 60.2 are cylindrical and configured to immobilize in rotation, according to the first or second axis of revolution A60.1, A60.2, the first and second parts 60.1, 60.2 relative to each other.

[0056] According to an embodiment visible in [Fig.5], the first lateral face 70.2 and the inner lateral surface 78.1 each comprise at least one longitudinal groove S1, S2 parallel to the first or second axis of revolution A60.1, A60.2. According to one configuration, the first lateral face 70.2 comprises first longitudinal grooves S1 distributed over its entire circumference. In the same way, the surface inner side 78.1 comprises second longitudinal ridges S2 distributed over its entire circumference, the first and second ridges SI, S2 being configured to fit into each other so as to immobilize in rotation, along the first or second axis of revolution A60.1, A60.2, the first and second parts 60.1, 60.2 relative to each other.

[0057] The holding system 64 comprises at least one stop 80, positioned projecting relative to the inner lateral surface 78.1, oriented towards the second axis of revolution A60.2, positioned at the first end 76.1 of the second part 60.2. The stop 80 is distant from the bottom 78.3 by a distance substantially equal to the height of the first section 70 of the first part 60.1. In operation, when the first section 70 of the first part 60.1 is in the housing 62, the first end 68.1 of the first part 60.1 is pressed against the bottom 78.3 of the housing 62 and the stop 80 is in contact with the shoulder 74 to hold the first section 70 of the first part 60.1 in the housing 62 of the second part 60.2.

[0058] According to one configuration, the stop 80 is a collar which extends over the entire circumference of the inner lateral surface 78.1. This stop 80 is dimensioned to ensure that the first section 70 is held in the housing 62 as a function of the stresses passing between the first and second parts 60.1, 60.2.

[0059] To allow the holding system 64 to deform, the first tubular section 78 comprises several slots 82, substantially parallel to each other and to the second axis of revolution A60.2, which each extend from the first end 76.1 over a given length and connect the inner and outer lateral surfaces 78.1, 78.2. The given length of each slot 82 is between half the depth of the housing 62 and said depth.

[0060] According to one arrangement, the slots 82 are regularly distributed over the circumference of the first tubular section 78, delimiting between them elastically deformable tabs 84. The number of slots 82, the given length of each slot 82, the thickness of the first tubular section 78 and the material of the second part 60.2 are determined so that the tabs 84 can flare sufficiently to allow each stop 80 to move apart in order to allow the first section 70 of the first part 60.1 to exit or enter the housing 62.

[0061] As illustrated in [Fig.7], the stop 80 has a first edge 80.1 configured to be in contact with the shoulder 74 as well as a second beveled edge 80.2 promoting the deformation of the tabs 84 during the introduction of the first section 70 of the first part 60.1 into the housing 62 of the second part 60.2.

[0062] According to one configuration, the second part 60.2 comprises a second section 86 located between the first tubular section 78 and the second end 76.2.

[0063] According to one embodiment, the first locking system 66 comprises at least one ring 88 configured to slide around the second part 60.2 between a first position, corresponding to the locked state, in which the ring 88 is close to the first end 76.1 and prevents the first tubular section 78 from flaring, and a second position, corresponding to the unlocked state, in which the ring 88 is spaced from the first end 76.1 and allows the first tubular section 78 to flare.

[0064] According to one configuration, the second section 86 has a cylindrical outer lateral surface in the extension of the outer lateral surface 78.2 of the first tubular section 78. In addition, the ring 88 is cylindrical and comprises an inner face 90 having a diameter substantially equal to that of the outer lateral surfaces of the first and second sections 78, 86 of the second part 60.2.

[0065] The ring 88 extends between first and second edges 88.1, 88.2. In the first position corresponding to the locked state, the first edge 88.1 is located near or at the first end 76.1 of the second part 60.2 and the second edge 88.2 is spaced from the second end 76.2. In the second position corresponding to the unlocked state, the second edge 88.2 is located near or at the second end 76.2 and the first edge 88.1 is spaced from the first end 76.1.

[0066] To keep the ring 88 around the second part 60.2, the latter comprises at least one bulge 92 positioned projecting relative to the outer lateral surface 78.2, at the first end 76.1 of the second part 60.2 as illustrated in [Fig.7]. According to one arrangement, a bulge 92 is provided on each tab 84.

[0067] According to embodiments visible in Figures 11 to 14, the connecting system 50 comprises at least one return element 94, such as a helical spring positioned around the second part 60.2, configured to push and hold the ring 88 in the first position corresponding to the locked state. According to these embodiments, the ring 88 is held in the second position, corresponding to the unlocked state, by an operator who grasps the ring 88 and moves it apart into the second position during the phase of introduction of the first section 70 of the first part 60.1 into the housing 62 of the second part 60.2.

[0068] According to embodiments visible in Figures 2 to 12, the connection system 50 comprises a second locking system 96 configured to occupy a first stable state in which the second locking system 96 allows the ring 88 to translate between the first and second positions as well as a second state stable in which the second locking system 96 blocks the ring 88 in the first position corresponding to the locked state.

[0069] According to configurations visible in FIGS. 1 to 10, the connecting system 50 comprises first and second locking systems 66, 96 and does not comprise a return element 94.

[0070] According to a configuration visible in Figures 11 and 12, the connecting system 50 comprises first and second locking systems 66, 96 as well as a return element 94.

[0071] According to another configuration visible in figures 13, 14, the connecting system 50 comprises a return element 94 and only the first locking system 66.

[0072] According to one arrangement, the first part 60.1 is integral with the column 46 and the second part 60.2 is integral with the head 48.

[0073] According to one configuration, the axis of revolution A60.1 of the first and second sections 70, 72 of the first part 60.1 coincides with the axis A46 of the column 46.

[0074] According to one configuration, the second part 60.2 is integral with the first face 54.1 of the body 54 of the head 48, the second axis of revolution A60.2 being substantially perpendicular to the first face 54.1 of the body 54 of the head 48. According to this configuration, in the presence of a return element 94, the latter is interposed between the ring 88 and the first face 54.1 of the body 54 of the head 48.

[0075] According to an embodiment visible in [Fig.l 1], the second locking system 96 comprises at least one rod 98 which extends between first and second ends 98.1, 98.2 as well as, for each rod 98, a conduit 100 passing through the body 54 of the head 48 and opening at the first and second faces 54.1, 54.2. The rod 98 and the conduit 100 are configured to allow the rod 98 to slide without play in the conduit 100. The latter is oriented so that the rod 98 can slide in a direction substantially parallel to the second axis of revolution A60.2 (parallel to the sliding direction of the ring 88). The conduit 100 is positioned in the extension of the ring 88 so that the first end 98.1 of the rod 98 can come into contact with the second edge 88.2 of the ring 88.

[0076] According to one configuration, the second locking system 96 comprises first and second rods 98, 98' diametrically opposite relative to the second part 60.2 as well as a crosspiece 102 connecting the second ends 98.2 of the first and second rods 98, 98'.

[0077] According to one arrangement, each rod 98, 98' has a length (distance separating the first and second ends 98.1, 98.2) determined so that the second end 98.2 of each rod 98, 98' projects and is spaced from the second face 54.2 of the body 54 of the head 48 when the ring is in the second position corresponding to the unlocked state and is located at or close to said second surface 54.2 when the ring 88 is in the first position corresponding to the locked state. Thus, the crosspiece 102 is in contact with the second face 54.2 of the body 54 of the head 48 when the first end 98.1 of each rod 98, 98' is in contact with the second edge 88.2 of the ring 88 positioned in the first position corresponding to the locked state.

[0078] The operation of the support 40 is described with reference to figures 2 to 9. Firstly, the column 46 is fixed to the structure 44 by means of the fixing system 52. Next, the head 48 is connected to the column 46. For this, the first tubular section 78 of the second part 60.2 connected to the head 48 is positioned just above the first section 70 of the first part 60.1 connected to the column 46. Next, the head 48 is correctly oriented relative to the column 46 by pivoting it around the axis A46 of the column 46. When the head 48 is correctly oriented, the ring 88 being in the second position corresponding to the unlocked state, the first tubular section 78 of the second part 60.2 is fitted around the first section 70 of the first part 60.1 connected to the column 46.In the presence of a return element 94, the operator maintains the ring 88 in the second position when positioning the first tubular section 78 of the second part 60.2 around the first section 70 of the first part 60.1.

[0079] When the first section 70 of the first part 60.1 is in the housing 62, the first end 68.1 of the first part 60.1 is pressed against the bottom 78.3 of the housing 62 and the stop 80 is in contact with the shoulder 74 and holds the first section 70 of the first part 60.1 in the housing 62.

[0080] The elongate element 42 is then positioned on the head 48, as illustrated in [Fig. 8]. When the elongate element 42 is pressed towards the second face 54.2 of the body 54 of the head 48 during its installation, it pushes each rod 98, 98' which itself pushes the ring 88 into the first position corresponding to the locked state, as illustrated in [Fig. 9].

[0081] Finally, the elongate element 42 is held pressed against the head 48 (more particularly against the second face 54.2 of the body 54) by means of a link 58, as illustrated in [Fig. 3]. Thus, the elongate element 42 prevents any movement of each rod 98, 98' which holds the ring 88 in the first position corresponding to the locked state.

[0082] According to the invention, if the first section 70 of the first part 60.1 is not correctly positioned in the housing 62 then the first tubular section 78 remains in the flared position and prevents the ring 88 from translating into the first position. Consequently, the crosspiece 102 remains spaced from the second face 54.2 of the body 54 of the head 48, preventing the elongate element 42 from being put in place.

[0083] The support 40 of the invention has a lower mass than that of a support of the prior art, which makes it possible to reduce the mass on board the aircraft. According to another advantage, the head 48 can be connected to the column 46 without tools and without checking a tightening torque. Finally, it is no longer necessary to check a tightening torque during maintenance operations in order to verify whether the head 48 is still correctly connected to the column 46.
