This invention relates to automobile luggage carriers and particularly to small automobile luggage carriers which can be utilized on station wagons, the rear trunk deck of conventional size cars or on the roof of smaller cars.

It is an object of this invention to provide an automobile luggage carrier which can be used on station wagons, the trunk lid of conventional size cars or on the roof of smaller cars; which is rigid and strong; which is low in cost; and which is neat and pleasing in appearance.

FIG. 20 is a fragmentary plan view of the strap mounting shown in FIG. 19.

FIG. 21 is a fragmentary sectional view taken along the line 21-21 in FIG. 10.

Referring to FIG. 1, the luggage carrier embodying the invention is adapted to be mounted on the roof of a station wagon, on the rear trunk lid of a conventional size car or on the roof of a smaller size car and comprises integral die cast end assemblies 20 connected by upper and lower side rails 21, 22 extending between the ends thereof and cross members 23. When mounted on the rear trunk lid, the end members 20 extend forwardly and rearwardly. When mounted on a top of a station wagon or a smaller size car, the end members 20 face the side.

As shown in FIGS. 9 and 11, each end assembly 20 comprises an upper rail 24, a lower rail 25 and central struts 26 and end struts 27 extending between the upper rail 24 and the lower rail 25. The entire unit is cast in one piece.

As shown in FIG. 11, the upper and lower rails 24,

25 are generally C-shaped in cross section and face with the curve or bulge portion thereof outwardly. A decorative plate 28 bearing medallions and the like may be cast integrally between the struts 26. A portion of lower rail 25 is preferably cut away at the area of medallion 28.

Referring to FIGS. 2 and 3, each end assembly 20 is formed with integral

hollow extensions

30, 31 adjacent the upper and lower ends of the struts 27 over which the side rails 21, 22 are telescoped and held in position by

screws

32, 33. To facilitate insertion of the rails, the ends of the

extensions

30, 31 are tapered as at 34. The cross section of the

extensions

30, 31 is preferably oval as shown in FIG. 6.

Referring to FIGS. 3, 4 and 10, each of the lower rail portions 25 is formed with longitudinally spaced integral extensions 35 that extend inwardly toward the opposite end member 20. As shown in FIGS. 3 and 5, the extensions 35 include a flat top surface 36, inclined flat side surfaces 37 extending downwardly from the edges of the fiat surface 36, curved lower surfaces 38 extending from the lower edge of the inclined surfaces 37 and flat upwardly and inwardly extending surfaces 39 extending from the lower edge of the surfaces 38. The central inner portion of each projection is recessed as at 40.

Each cross member 23 is telescoped over opposed projections 35 and held in position by screws 41 threaded upwardly from recess 40 through the projection 35 and into the cross member 23. Extending between the lower side rails 22, a resilient insulating strip 23a may be provided and engages the car top or trunk lid (FIG. 21).

As shown in FIG. 3, the cross member 23 is generally channel shaped and includes a Hat top 42a which engages surface 36, inclined sides 4212 which are spaced from the surfaces 37, vertical sides 420 that engage the surfaces 38 and inwardly extending flanges 43 that engage the surfaces 38.

The shape of the projections 35 permits cross rails of different cross sections to be used on the same projection. For example, an extruded cross rail 45, as shown in FIG. 6, may be used which has an internal configuration including a fiat surface 46, inclined surfaces 47, curved surfaces 48 and flanges 49 so that it is telescoped and makes contact with the

surfaces

36 and 38 of the projection 35. At the same time, the exterior configuration of cross member 45 is substantially different in appearance having a ribbed surface.

Alternately, extruded cross member 50, shown in FIG. 7, may be used, which has a different exterior appearance and an internal configuration including flat surface 51, inclined surfaces 52, straight surfaces 53 and flanges 54. This telescopes over the projection 35 and makes contact with the

surfaces

36 and 38 of the projection 35.

A further type of cross member 55 is shown in FIG. 8 and is made of sheet metal and includes an inwardly curved concave surface 56, a vertical surface 57 and flanges 58 so that in this form, when the cross member 55 is telescoped over the projection 35, contact is made with the

surfaces

37 and 38 of the projection 35.

Referring to FIGS. 3 and 10, each end member 28 is also formed with bosses 68 adjacent the end struts 27 having a threaded opening 61 for receiving a screw 62 that supports an L-shaped bracket 63. Screws 64 are threaded downwardly through the bracket 63 into the car top or trunk lid panel P to retain the automobile luggage carrier in position.

In order to accommodate the mounting of the carrier on car tops or trunk lid panels which have a curvature, the modified form of the invention such as shown in FIGS. 12-16 can be used and comprises end assemblies 70 which include an upper rail 71, a lower rail 72 and central struts (not shown) and end struts '73. However, instead of having integral

hollow extensions

30, 31, each end assembly 71 is provided with removable

hollow extensions

74, 75.

Removable extensions

74, 75 are substantially identical in construction and include a flat end surface 76 (FIGS. 14, 17) which is adapted to abut against a corresponding surface 77 on the end assembly 70. The outer surface 78 of each extension is generally oval. In order to hold each extension in position, projections 79 are provided and extend into complementary recesses 80. A screw 81 is threaded through surface 76 into an opening 82. It can be seen that the angle which each

extension

74, 75 makes with respect to the end assembly 70 depends upon the surface 7611. By having

removable extensions

74, 75 with end surfaces 76a at varying angles to the axis of the openings 82 the angle of the extensions can be changed and as a result the end rails and struts which are placed over the

removable extensions

74, 75 can more nearly accommodate variations in the curvature of the luggage carrier.

Instead of utilizing the mounting bracket 63 shown in FIGS. 3, 10, and 18 to mount the carrier, a strap assembly can be used as shown in FIGS. 19 and 20. As shown, the lower rail 25 of each end assembly is arcuate in cross section and a bracket 85 having a hook 86 thereon can be engaged with the rail 25 at various positions along the length of the carrier. Bracket 85 includes an upstanding flange 87 at the other end thereof into which a screw 88 is threaded. The screw 88 has an enlarged head 89 that abuts the sides of an opening in a bracket 90. The bracket is in turn engaged with one of a plurality of openings 91 in a strap 92. The lower end of the strap has a hook member 93 fastened thereto by a rivet 94 and engaging the drain trough E of the car top. A locking tab 95 projects downwardly from a plate 96 held in position by a screw 97 into the end of trough E to positively lock the strap. A plastic or rubber sleeve 98 can be provided over the strap to prevent scratching of the car top.

By the above arrangement, the strap can be engaged with the car top carrier at various points along the end of the

assemblies

20 or 75.

It can thus be seen that there has been provided an automobile luggage carrier which is rigid and compact; which can be used on the trunk lid of conventional size automobiles or on the roof of smaller size automobiles; which is simple in construction and low in cost.
