L AR ATTACHED TO THE AGE C RIER CK-WHEEL STAYS 0F CYCLES Filed July 9, 1948 Sheets-Sheet 2 Patented Jan. 30, 1951 UNITED LUGGAGE CARRIER. ATTACHED TO THE BAOK-VVHEEL STAYS OF CYCLES Jules Bachmann, Dubendorf, Switzerland, assignor to Max Schneider, Zurich, Switzerland Application July 9, 1948, Serial No. 37,825 In Switzerland July 1, 1947 2 Claims.

connected to two fitting surfaces arranged at right angles to each other, and on these surfaces springs act in such a manner that the side flaps are held in the horizontal or vertical position.

One execution of the object of the invention is illustrated by way of example in the accompanying drawing, in which:

Fig. 1 .is a perspective View of the lug age carrier;

Fig. 2 a cross-section on the line IIII of Fig. 1, and

Fig. 3 a section on the line III-III of Fig. 2.

Fig. 4 is a perspective view of the luggage carrier with the side flaps raised up.

The new luggage carrier has a main or primary supporting frame 2, known per se, arranged for attaching to the fork I of the back wheel, and having a horizontal part Ed on which objects can be laid. Further, on the primary frame 2 a hinged clamping piece :3 is fitted in known manmen standing under the influence of a torsion U spring 3. On the two stays forming the part 2a, two traverses 5 are arranged, in each of which a flat spring t is fixed. Two rotatable cams l are pivotably supported on bolts 8 in each traverse 5. Each of the rotatable cams i has two fitting surfaces 8, 9a slightly bent inwards and standing at right angles to each other; on them lie the ends of the springs 6. By means of the said rotatable cams, side or secondary suppor ing frames it are swivellingly supported in the traverses 5. Each side flaps has two arms ll, each of which is firmly connected to a rotatable piece To each of the secondary frames iii a frame-shaped holder 92 is hinged and stands under the influen e of a torsion spring is. The latter tends to press the upper part of the holder 12 on to the arms I l; i. e. an object laid between them will be held firmly clamped, fluted rubber rollers H5 being also fixed on the holder to ensure a better hold for the object in question. Also the rubber rollers IE will make it more dinicult for objects firmly clamped between the holder l2 and the arms i! to be unintentionally displaced. With the secondary frames Iii in the depending vertical position (Fig. 1), objects can be firmly held independently in the two secondary frames and also under the clamp :l. The springs 6 are chosen of such strength, and the pressure of the spring ends on the fitting surfaces are chosen so strong, that the side iii cannot swing unintentionally round the bolts 8.

But if the secondary frames it are turned up through they come to lie in the horizontal position. The springs 6 then press on to the fitting surfaces to; and hold the side flap-s in the horizontal position as illustrated in Fig. i. The arms 5 l and the part 2a now lie in one plane, so that comparatively large objects, such as attache cases, etc. are supported on a practically even surface and do not sag downwards on both sides of the clamp at.

What I claim as my invention and desire to secure by Letters Patent is:

1. A luggage carrier for cycles comprising, a primary supporting frame adapted to be attached to the rear fork of the cycle, said primary supporting frame including two spaced substantially parallel parts extending rearwardly and horizontally when said frame is attached to said fork, two secondary supporting frames each comprising two parallel arms of angular shape pivotally attached with one of their ends to said parallel parts of said primary supporting frame to project laterally therefrom, cooperating means on said primary supporting frame and on said arms for retaining said secondary supporting frames selectively in two positions, one of said two positions constituting a folded position in which said secondary supporting frames depend vertically downward and the other position constituting an unfolded position in which said secondary supporting frames project horizontally outward and in which said arms are positioned substantially in the same plane as said spaced parallel parts of said primary supporting frame, said angular shaped arms being arranged in such manner that the ends thereof opposite the ones pivotally connected to said primary supporting frame are directed vertically upward when said secondary supporting frames are retained in their unfolded position, said last named ends of said arms being connected with each other by a transverse member extending parallel to the pivot axis of said angular shaped arms, a frameshaped holder pivotally mounted on said transverse member, and spring means mounted on said transverse member, and operatively connected with said holder to yieldably urge the same in a direction towards said angular shape arms, whereby the carrier forms a three-sided enclosed apparatus especially designed for large packages when said secondary supporting frames are retained in their unfolded position, and whereby said carrier forms a multiple compartmentalized structure when said secondary supporting frames are retained in their folded position.

2. A luggage carrier for cycles comprising, a primary supporting frame adapted to be attached to the rear fork of the cycle, said primary supporting frame including two spaced substantially parallel parts extending rearwardly and horizontally when said frame is attached to said fork, two secondary supporting frames each comprising two parallel arms of angular shape pivotally attached with one of their ends to said parallel parts of said primary supporting frame to project laterally therefrom, cams fixedly secured to said ends of said arms, spring means secured to said primary supporting frame and engaging said cams whereby said secondary supporting frames are adapted to be adjusted and retained selectively in two positions, one of said two positions constituting a folded position in which said secondary supporting frames depend vertically downward and the other position con stituting an unfolded position in which said secondary supporting frames project horizontally outward and in which said arms are positioned substantially in the same plane as said spaced parallel parts of said primary supporting frame, said angular shape arms being arranged in such manner that the ends thereof opposite the ones pivotally connected to said primary supporting frame are directed vertically upward when said secondary supporting frames are retained in their unfolded position, said last named ends of said arms being connected with each other by a transverse member extending parallel to the pivot axis of said angular shape arms, a frame-shaped holder pivotally mounted on said transverse member, and spring means mounted on said transverse member and operatively connected with said holder to yieldably urge the same in a direction towards said angular shape arms, whereby the carrier forms a three-sided enclosed apparatus especially designed for large packages when said secondary supporting frames are retained in their unfolded position, and whereby said carrier forms a multiple compartmentalized structure when said secondary supporting frames are retained in their folded position.
