- the attachment member 42 can be in a rest position, that is to say that it is then not deformed, when the movable element 44 is in the rest position, or in a position pre-assembly, between the rest position and the attachment position, when the movable element 44 is in a pre-assembly position.
- the assembly method may include a prior step of centering the fixing assembly 1 relative to the support wall 3 during which the centering member 46 is placed through orifice 31 .
- the fixing assembly 1 is brought closer to the support wall 3 until the attachment members 42 also extend through the orifice 31, always in the rest or pre-assembly position, that is to say without necessarily being in contact with the support wall 3.
- the fixing assembly 1 is then positioned so that the housing 5, in particular its base 54, bears against the first surface 301 of the support wall 3, as seen in Figures 14 and 15.
- hook 42 and the centering member 46 extend through the orifice 31, the hook members 42 extending around the periphery of the orifice 31 or a rim bordering the orifice 31 and the fixing assembly is in an intermediate configuration called “pre-assembly”.
- the displacement means 6 of the blade 4 is then tightened.
- the latter is screwed, that is to say moved in rotation around the axis of rotation 600 so as to move the movable element 44 of the blade 4 towards its fixing position.
- the elastically deformable tongue 45 is moved so as to be brought closer to the main plane 400 of the body 41, in other words so as to reduce the existing space K, along the first direction D1, between the end portion 451 of the tongue 45 and the main plane 400.
- the tongue 45 is arranged in the blade 4 in such a way that the body 41 is interposed between the tongue 45 and the first side 51 of the casing 5 when the fixing assembly 1 is assembled.
- the tightening of the displacement means 6 thus gradually displaces the tongue 45 so as to bring it closer to the opening 53, the latter rising along the body 41 of the displacement means 6.
- the reverse configuration could be considered, that is to say that the tab 45 can be interposed between the body 41 of the blade 4 and the first side 51 along the first direction D1.
- the tightening of the displacement means 6 and the displacement of the tab 45 consequently causes the gradual displacement of the blade 4 in the housing 5.
- the movable element 44 remains stationary along the second direction D2, held by the moving means 6, while the body 41 of the blade 4 is moved according to a translational movement T1 relative to the casing 5 along this same direction.
- a movement is here partly conditioned by the position of the holding members 56 of the blade 4 integrated into the housing 5, such members guiding its movement along the second direction D2.
- the body 41 of the blade 4 is moved in order to be moved away from the support wall 3 along the second direction D2, thus bringing the hooks 421 of the attachment members 42 closer to the second surface 302 of the wall of support 3.
- the attachment members 42 are brought closer to the holding member(s) 56 until the latter come into contact with the attachment members 42.
- the retaining 56 here one of the ribs 561 forming the rail, exerts a force on the inclined segment 43, elastically deformable.
- the latter is then moved so as to approach the main plane 400 of the body 41 so as to place the hook 421 in engagement with the support wall 3.
- the movement of the body 41 of the blade 4 relative to the housing 5 results in a step of hooking the blade 4 during which the hooking members 42 are moved towards the hooking position.
- the force exerted by the holding means 57 on the attachment member 42 causes in particular a tilting, or pivoting, of the attachment members 42.
- Such tilting B1 is in particular produced around a tilting axis orthogonal to the first direction D1, in particular parallel to the third direction D3.
- the housing 5 is advantageously configured so as to cooperate with the member hook 42 in order to move it between its rest position, or pre-assembly, and its fixing position.
- At least a part of the housing 5, in this case at least one holding member 56, is arranged across a path followed by the gripping member 42 when the blade 4 is moved relative to the housing 5
- the holding member 56 is arranged across a trajectory defined by a translational movement along the second direction D2.
- a free end portion of the rib 561 configured to extend around the support wall 3 and to cooperate with the attachment member 42 when the blade 4 is moved within the housing 5, may include an angled edge 573.
- the tightening of the displacement means 6 by rotation around the axis of rotation 600, parallel to the first direction D1 causes the displacement of the movable element 44 along this same direction so as to bring it closer to the body 41 .
- the attachment member 42 is brought closer to the support wall 3 and the blade 4 is moved in such a way that the proportion of the blade extending within the interior volume 500 of the casing is increased relative to what is observed during the rest configuration or pre-assembly of the fixing assembly 1 .
- the blade 4 is thus moved in the housing 5 until the trajectory of the attachment member 42 is impeded by the housing 5 in such a way that the housing exerts a force on the attachment member 42 causing a change of position to its hanging position.
- a change is made by tilting around the tilting axis orthogonal to the first direction D1 and to the second direction D2 as described above until the attachment member 42 comes into contact with the support wall 3, in particularly in grip of the latter.
- the attachment member 42 can be deformed in elastic bending by the action of the edge of the orifice 31.
- the fixing assembly 1 is thus mounted on the support wall 3.
- the attachment members 42 are in the attachment position, cooperating with the support wall 3 in order to limit the movements of the housing 5, and therefore of the element to be fixed 2, along one direction of the second direction D2 while the housing 5 prevents any movement in the opposite direction of this same direction.
- the support wall 3 is thus engaged between the attachment members 42 on the one hand and the housing 5 on the other.
- Blade 4 and housing 5 are then held in a fixed position relative to each other.
- the tongue 45 of the blade 4 is pressed by the displacement means 6 in a position such that the dimension of the space K is strictly less than that observed when the tongue 45 is in the rest or pre-assembly position.
- the reverse steps are carried out.
- the displacement means 6 is thus loosened in order to allow the return of the movable element 44 and of the attachment member 42 to their respective rest positions, that is to say beyond the preposition. - mounting of the attachment member 42.
- the loosening of the displacement means 6 by rotation around the axis of rotation 600 causes the displacement of the movable element 44 along this same direction so as to move it away from the body 41 .
- the body 41 is, consequently, moved along a direction orthogonal to the first direction D1, in particular the second direction D2, preferably, according to a translation movement in order to bring the blade 4 closer to the support wall 3 and thus move the attachment member 42 away from it.
- the blade 4 is moved relative to the housing 5 in such a way that the latter no longer exerts any force on the attachment member 42, the latter then returns from itself to its rest position in which it no longer interferes with the orifice 31 .
- the attachment member 42 is thus detached from the support wall 3 and extends facing the orifice 31 so as to allow the extraction of the fixing assembly 1, in particular of the centering member 46 and hooks 42.
- the present invention thus proposes a fixing assembly which advantageously makes it possible not to directly use conventionally used fixing means, such as screws or clips, at the level of a support wall for fixing an element to be fixed.
- fixing means such as screws or clips
- Such an indirect fixing makes it possible to overcome some of the sizing constraints specific to the fixings conventionally used. For example, in the case of a lighting device as described in the present description, it is then possible to reduce the dimensions of the support wall along the first direction D1 and in particular along the transverse direction Oy, thus making the fixing assembly more suitable for compaction constraints of the rear faces as may be the case in the automotive environment, or more generally, compaction of the dimensions of an element to be fixed.
- the present invention also allows a simplification of the fixing, as well as the production, of parts intended for congested environments by moving the fixing means conventionally observed from a perpendicular positioning at the level of the support wall towards a positioning at the level of the support wall. within the element to be fixed transverse or parallel to said wall.
- the use of tools necessary for fixing is facilitated by moving the point requiring the use of such tools away from the fixing wall, thus reducing the constraints of space, but also the risk of damage.
- the fixing means in this case the displacement means, here extends at a distance from the support wall, along a direction not perpendicular to the support wall, and that the tool used can then be arranged perpendicular to the side of the element to be fixed carrying the fixing assembly.
