Assembly for guiding the longitudinal sliding movement of a sub-assembly
An improved arrangement for a transverse dividing element includes an upper cross beam ( 32 ), each free end of the cross beam being guided longitudinally by way of an associated guiding structure. The guiding structure includes a slide having a groove in which a free end ( 34 ) of the cross beam ( 32 ) can slide longitudinally, the free end being equipped with guiding ( 92, 100 ) and a locking ( 102, 104 ) element. The transverse dividing element can be used to guide an upper cross beam supporting a transverse element that is used to divide the internal space of an aircraft cabin.
1. An assembly for guiding the longitudinal sliding movement of a sub-assembly ( 32 ), comprising:
a guide rail ( 36 ) comprising a groove ( 40 ) with an inside wall defining a longitudinal guideway ( 93 ), the body of the guide rail ( 36 ) comprising a longitudinal front groove ( 40 ) open in a transverse direction; and
a guide runner ( 34 ) configured to cooperate with the groove ( 40 ) of the guide rail ( 36 ) comprising at least one locking system ( 102 ) for locking the runner ( 34 ), when the runner is engaged in the guide rail ( 36 ), in any longitudinal position relative to the guide rail ( 36 ), the guide runner ( 34 ) further comprising rolling elements ( 92 ) each comprised of a pair of mutually oblique rollers configured to roll along longitudinal guideway ( 93 ) of the groove ( 40 ),
wherein the guideway ( 93 ) comprises opposing inner walls each having faces with cylindrical arcs of approximately circular section, and
wherein the locking system ( 102 ) comprises at least one locking shoe ( 104 ) movable between i) a retracted position and ii) a locked position in which the shoe engages by friction with a locking surface of the body of the guide rail ( 36 ).
2. The arrangement as claimed in claim 1 , wherein the locking shoe ( 104 ) comprises a locking sole ( 106 ), the locking surface comprises a longitudinal planar locking track ( 51 ) formed in the groove ( 40 ), and the locking shoe is configured to engage with the longitudinal planar locking track ( 51 ).
3. The arrangement as claimed in claim 2 , wherein the inside wall of the groove ( 40 ) has at least one longitudinal electrically conducting track ( 180 ) contacted by at least one electrical contact element ( 190 ) carried by the guide runner ( 34 ) and connected electrically to at least one electrical and/or electronic component associated with said sub-assembly.
4. The arrangement as claimed in claim 1 , wherein the locking shoe ( 104 ) comprises a locking sole ( 106 ), the locking surface comprises a longitudinal locking track ( 47 , 49 ) formed outside of the groove ( 40 ), and the locking shoe is configured to engage with the longitudinal locking track ( 47 , 49 ).
5. The arrangement as claimed in claim 4 , wherein the inside wall of the groove ( 40 ) has at least one longitudinal electrically conducting track ( 180 ) contacted by at least one electrical contact element ( 190 ) carried by the guide runner ( 34 ) and connected electrically to at least one electrical and/or electronic component associated with said sub-assembly.
6. The arrangement as claimed in claim 1 , wherein the rolling elements ( 92 ) are arranged at opposite longitudinal ends ( 100 ) of the of the guide runner.
7. The arrangement as claimed in claim 6 , wherein the inside wall of the groove ( 40 ) has at least one longitudinal electrically conducting track ( 180 ) contacted by at least one electrical contact element ( 190 ) carried by the guide runner ( 34 ) and connected electrically to at least one electrical and/or electronic component associated with said sub-assembly.
8. The arrangement as claimed in claim 1 , wherein the inside wall of the groove ( 40 ) has at least one longitudinal electrically conducting track ( 180 ) contacted by at least one electrical contact element ( 190 ) carried by the guide runner ( 34 ) and connected electrically to at least one electrical and/or electronic component associated with said sub-assembly.
9. The arrangement as claimed in claim 8 , wherein said electrical contact element ( 190 ) is a sliding contact.
10. The arrangement as claimed in claim 8 , wherein the runner ( 34 ) supports a movable block ( 210 ) configured to support said electrical contact element ( 190 ) and which is movable transversely between i) a retracted position of rest, in which said electrical contact element is not in contact with the at least one conducting track ( 180 ), and ii) an advanced position of contact with the at least one conducting track ( 180 ).
11. The arrangement as claimed in claim 10 , wherein movements of the movable block ( 210 ) between the retracted position and the advanced position are controlled by an action of an operating mechanism ( 108 , 114 ) of said locking shoe ( 34 ).
12. The arrangement as claimed in claim 11 , wherein the movable block ( 210 ) is configured to return elastically to its advanced position of contact.
13. The arrangement as claimed in claim 10 , wherein the movable block ( 210 ) is configured to return elastically to the advanced position of contact.
14. The arrangement as claimed in claim 8 , wherein the guide runner ( 34 ) comprises a brush ( 230 ) for cleaning said conducting track ( 180 ).
