Loading rail and sliding block for a loading rail
A loading rail has a cross-sectional profile which is uniform over at least part of the length of said loading rail, has, on an upper side, a longitudinal groove for receiving at least one sliding block, the longitudinal groove being constricted in an upper region by at least one web, which is attached to a side wall of the longitudinal groove, to form a longitudinal slot, and the web bearing at least one downwardly projecting projection, wherein the projection forms an undercut on a side facing away from the longitudinal slot, as seen from below. The disclosure also relates to a sliding block for a loading rail.
1. A loading rail comprising:
a cross sectional profile that is uniform over at least part of a length of said loading rail, the cross sectional profile including:
a longitudinal groove for receiving at least one sliding block; and
at least one web attached to a side wall of the longitudinal groove on an upper side thereof, to form a longitudinal slot constricting the longitudinal groove in an upper region thereof, the web bearing at least one projection, wherein the projection includes an inner radiused portion and a straight portion that extends away from the radiused potion and the web and toward the side wall along an interior angle between 45° and 55° and defines an undercut on a side thereof facing away from the longitudinal slot.
2. The loading rail as claimed claim 1 , wherein the at least one projection is adjacent to the longitudinal slot.
3. The loading rail as claimed in claim 1 , wherein the straight portion Of the at least one projection is directed toward a guide surface of the loading rail.
4. The loading rail as claimed in claim 3 , wherein the guide surface defines a slope on die inside of a side wall of the loading rail, the slope flaring outwardly with respect to the longitudinal groove.
5. The loading rail as claimed in claim 1 , wherein the straight portion of the projection includes a first surface defining a portion of the undercut and a second surface opposite the first surface, the first surface and second surface extending generally parallel to each other.
6. The loading rail as claimed in claim 1 , wherein the longitudinal groove is constricted by two mutually opposite webs which each bear a projection, the two projections forming respective undercuts.
7. The loading rail as claimed in claim 1 , wherein the loading rail is of mirror-symmetrical design with respect to a longitudinal center plane.
8. The loading rail as claimed in claim 1 , wherein the loading rail has a flat lower side.
9. The loading rail as claimed in claim 1 , wherein the loading rail is installed on a vehicle.
10. A loading rail comprising:
a longitudinal groove constricted in an upper region by at least one web attached to a side wall of the groove to form a longitudinal slot, the web bearing at least one projection having a straight portion thereof extending along an angle of between 45 ° and 55°simultaneously away from the web and toward the side wall and defining an undercut expanding in a direction away from the longitudinal slot on a side of the projection facing away therefrom.
11. The loading rail as claimed in claim 10 , wherein the loading rail extends along a length thereof and comprises a cross-sectional profile which is uniform over at least part of the length of the loading rail.
12. The loading rail as claimed in claim 10 , wherein the at least one projection is adjacent to the longitudinal slot.
13. The loading rail as claimed in claim 10 , wherein the loading rail is installed on a vehicle.
14. The loading rail as claimed in claim 10 , wherein the projection further extends outwardly with respect to the longitudinal slot.
15. The loading rail as claimed in claim 10 , further including:
at least one profile element extending laterally outward from the side wall of the longitudinal groove on a side of the side wall opposite the longitudinal groove, the at least one profile element defining a portion of one of a floor panel or a roof panel of a vehicle.
16. The loading rail as claimed in claim 15 , wherein:
the longitudinal groove is a first longitudinal groove; and
the loading rail further includes a second longitudinal groove, the at least one profile element coupling the first longitudinal groove with the second longitudinal groove.
17. The loading rail as claimed in claim 1 , wherein the cross sectional profile further includes:
at least one profile element extending laterally outward from the side wall of the longitudinal groove on a side of the side wall opposite the longitudinal groove, the at least one profile element defining a portion of one of a floor panel or a roof panel of a vehicle.
18. The loading rail as claimed in claim 17 , wherein:
the longitudinal groove is a first longitudinal groove; and
the cross sectional profile further includes a second longitudinal groove, the at least one profile element coupling the first longitudinal groove with the second longitudinal groove.
