Aug. 25, 1953 K. R. COSTIKYAN LUGGAGE CARRIAGE Filed July 20, 1949 Patented Aug. 25, 1953 UNITED? STATES PATENT OFFICE LUGGAGE CARRIAGE Kent R. Costikyan, Montclair, N. J 7
Application July 20, 1949, Serial No. 105,823 I 1 Claim. (o1. 280-35) 4 r The present invention relates to wheeled luggage carriages of the type adapted temporarily to be mounted on pieces of luggage, such as suitcases, trunks and the like to facilitate their manual transportation. 7
r A general object of the present invention is to provide such a device which is readily and economically constructed and easily manipulated, and is of very light weight and compact in form while being readily collapsible or compactly packable to permit desirable storage with minimum occupancy of space in luggage when not in use; such apparatus being readily attached and detached in a simple manner, preferably adaptable to various'shapes and sizes of different types of luggage pieces, and readily employed with maximum comfort by people of diiferent heights for easy rolling transport of such luggage pieces without interfering with the carrying thereof on stair ways.
A more specific object of the invention is to provide such apparatus in a form which permits Wheeled support of one, end edge of such luggage pieces with secure seating thereinof the corners at both ends of that edge; the device preferably being readily adjustable to the'dimensions thereof and being simply and removably fastened thereto in a most eflicient and secure manner by strap or tying means extendingtoward the diagonally opposite end edge. r r
A further object of the'present invention is to provide an embodiment of the device which is readily adapted to eifectivemanual transport use either as a single unit or in pairs, with one in the latter case serving at one endedgeof the luggage piece as the wheeled carriage and the other at the diagonally opposite end edge as a strap anchorage and hand engagement device. 1 1
. Cther objects of the invention will in part be obvious and will in part appear hereinafter,
- The invention accordingly comprises the featuresof construction, combination of elements and arrangement of parts, which will be exemplified in the construction hereinafter set forth, and the scope of' the invention will be indicated in the claim.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:
Fig. 1 is a perspective view of. an embodiment of the device of the present-invention showing it mounted in a particular manner upon a large suitcase, the outlines of which are indicated in dotted lines withparts broken away, for wheeled support of the latter; p j i Fig. 2 is another perspective view of the carriage structure shown in Fig. 1,.With outlines'of a suitcase mounted thereon being indicated in dotted lines and with parts broken away, showing a modification of the harness means employed to secure the suitcase upon the carriage, and with the assembly shown tilted to normal wheeling position;
Fig. 3 is an enlarged perspective view of one of the two complementary members of the carriage device shown in Figs. 1 and 2 which together serve as a unitary carriage when mounted together-and equipped with wheels; and
Fig. 4 is a top plan view of the structure shown in Fig. 2 with dotted line portions of the suitcase omitted in order to avoid confusion.
Referring to the drawings in which like numerals identify similar parts throughout, it will be seen that an embodiment of the present invention comprises a carriage structure formed of a pair of complementary members 5, 5-, each in the form of a V-shaped, elongated unit made from rigid material, such as lightmetallic composition or plastic. By reference to Figs. 1 and 2, it will be seen that each member 5 comprises a relatively narrow, elongated, rectangular bottom panel 6 flanked on both longitudinal sides by substantially rectangular, elongated side panels I, I. As best seen in Fig. 2, the two side panels 1, 7 are arranged substantially normal or at ninety degrees to each other, with the medially interposed bottom panel 6 arranged substantially at.
one hundred and thirty-five degrees to each. An apertured end piece 8 is provided in the form of a cross bar extendin from the outer corners at 9, 9 of side panels 1, 1. Each member 5 is provided with means for supporting a roller or a wheel in the nature of a pair of axially-apertured, projectingmembers or ears l0 and I l extending substantially normal to and outwardly away from bottom panel 6. Ears If! and II are laterally spaced to receive a'wheel I2 therebetween, rotatably supported on an axle I3 extended through holes [4, it in those ears, as shown.
Each side panel 1 is provided with a longitudinally-extending, elongated slot l5, and a notch I6 is provided in its outer edge near the corner 9. Cross bar 8 has its inner edge provided with a notch I! to serve as a strap seat extending substantially normal to a line approximately bisecting the angle between side panels 1, 7. Notch l7 prevents the strap from undesirably sliding along cross bar 8 and thus predetermines the location of the strap anchorage. In a preferred construction, the ear! I is formed by striking out and bending up a portion of the bottom panel 6, as indicated in Fig. '2, andv an extension of an end of the latter is bent up to provide the ear I 0. Although it is possibleto form the member 5, shown I V in Fig. 2, by means of a casting-or molding procedure, it is preferred to stamp it out of sheet metal, with the bar 8 formed as an integral part of one end of one side panel 1 at 9 and having the free end of that bar subsequently welded to the opposite end edge of the other side panel I at 9', after shaping. Alternately the bar 8 may be stamped as a separate piece and welded on at both ends.
Two such members as shown in Fig. 2, after equipping each with a wheel ii, are then'slid ably connected together, such as by means of a pair of carriage bolts l8, I8, each extended through aligned slots I5, l5 of both members, and upon the threaded end of which is mounted a wing nut i9. With loosening of the wing nuts l9, [9 it will be seen that a pair of complementary members 5, 5 may be slid longitudinally relative to each other so as to adjust the distance between their cross bars 8, 8. Such sliding connection of the pair of members 5, 5 also per- .mits compact packing thereof by telescoping them toward each other, and in an actual embodiment of the invention, such carriage structure is easily packed within a box four inches by four inches by eight inches (4" x l" x 8") in size.
As proposed in Fig. 1, such carriage construction may be mounted on a large suitcase, such as that indicated in dotted lines at 25.1, by loosening the wing. nuts [9, l9 and seating an end edge 2! of the suitcase within the troughdike seat provided by the carriage. Members 5, 5 are then slid toward each other so as to bring the cross bars 8, 8 snugly up against opposite sides or" the suitcase, after which wing nuts 19, I9 are tightened. It'is intended that the carriage so fittedon the end edge 2! of suitcase 2 be temporarily and securely held thereon by means of diagonally-arranged tying members. Such members may comprise a pair of adjustable straps 22, each having one end 2'3 fastened about one of" the cross bars "8 and seated within the notch- H therein. The other end M-of each flexible strap 22 may likewise be fastened toa similar member 5 of a similar carriage unit fitted on the diagonally opposite corner edge 25. Thus, one carriage unit may serve as a wheeling device, with the other carriage unit serving as an anchorageymeans for the diagonal straps 22,. and also as means forengagement by thehands of a person to facilitate wheeling the suitcase in a tilted position if swung over to the right as viewed in Fig. 1 substantially to that indicated in Fig. 3'. In' such case, it may also be desirable to substitute for the wheels ['2', i2 and their axles l3; iirof one carriage unit a through rod 28 to serve as a cross bar easily grasped by the hands for manipulating the carriageequipped suitcase.
As proposed in Fig. 3, the carriage unit'may be equipped with a flexible and adjustable straploop 2? having its ends 28 respectively secured to cross'bars 8,; 8," and of sumcient length as to pass around the opposite endv 29 of suitcase. 26 up to the vicinity of the diagonally opposed end edge 25. The flexible strap loop. 2T of the modification shown in' Fig. 3 is provided with a fiexibleandadiustable length of auxiliary strap having a loop '31 slidably receiving strap 27. The auxiliary strap 31! is of such length as to permit it to be lapped up over end edge. 25. of suitcase 26' and down to handle 32' thereof for fastening thereto as indicated. Strap loop 21 may be additionally provided'with a handle 33' to facilitate handling of the piece of luggage 4 which may be easily wheeled along in the tilted position shown therein. The adjustability of strap loop 21 may be provided by well known buckle means hidden from view on the far side of luggage piece '20 in Fig. 3.
As indicated in Fig. 3, the notches l6, IS in the edges of the side panels I, l accommodate glide buttons 34, 34, or like projections, with which pieces of luggage are frequently equipped.
It'will' thus be seen that the objects set forth above, among those made apparent from the preceding description, are efliciently attained and, since certain changes may be made in the above construction and different embodiments of the invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in. a limiting sense.
It is also to be understood that the following claim is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
Having described my invention, what I claim as new and desire to secure by Letters Patent is:
In a luggage carriage having a pair of complementary members, each member comprising a one-piece, rigid structure having a narrow, elongated, planar bottom panel of quadrilateral configuration; a pair of' elongated, planar side panels of quadrilateral configuration flanking opposite sides of said bottom panel, and each.
