United States Patent SUITCASE Cordelia Dobyns, Azusa, Calif.

Application July 22, 1953, Serial No. 369,663 6 Claims. (Cl. 190-43) The present invention relates to suitcases and particularly to collapsible suitcases.

More particularly still the invention relates to a collapsible suitcase having a framework which may be folded to occupy a very small space for storage and which when in use is covered with a fabric casing or cover which may likewise be folded when removed from the framework and stored in a very small space. Moreover, due to the removability of the cover the cover may readily be washed or otherwise cleaned and the entire device thus readily stored and readily cleaned.

It is an object of the invention to suitcase.

It is another object of the invention to provide such a collapsible suitcase arranged so that the casing member thereof may be removed from the frame and the frame thereupon folded to substantially flat condition for storage or for transportation.

It is a further object of the invention to provide such a collapsible suitcase having a fabric casing member which may be removed from the collapsible framework for washing or cleaning, storage or transportation.

Other objects and features of the invention will be apparent when the following description is considered in connection with the annexed drawings, in which,

Figure 1 is a perspective view of the collapsible suitcase of my invention as set up for use. This View shows the suitcase in its closed condition;

Figure 2 is a perspective view of the suitcase of Figure 1, showing the suitcase lying on one of its larger sides and showing the top open as the case would appear when ready to be packed;

Figure 3 is a perspective view of the collapsible framework showing that framework in the position which it would assume when in use;

Figure 4 is a top plan view of the framework of Figure 3; and

Figure 5 is a vertical cross-sectional view of the framework of Figures 3 and 4, the view being taken on the plane of the line 55 of Figure 4. This view shows in full lines the framework in its partially collapsed condition and in dotted lines the framework in its open condition.

Referring now to the drawings, and particularly to Figures 3, 4 and 5 thereof, there is shown a framework comprising the two frame members and 11. The frame member 10 consists of a pair of horizontally extending

angle members

12 and 13 joined by the diagonally extending

end members

14 and 15. Similarly the frame member 11 comprises the horizontally extending

angles

16 and 17 joined at their ends by the diagonally extending

members

13 and 26. Frame members 19 and 11 are pivotally interconnected by means of the rivets or other

suitable fastenings

21 and 22, the rivet 21 extending through apertures located centrally of

members

14 and 18 and rivet 22 extending through apertures located centrally in members and 20.

Fixed to the frame member 12, adjacent the ends thereprovide a collapsible of, are two

brackets

23 and 24. In like manner, fixed to the member 16 adjacent its ends and respectively opposite the

brackets

23 and 24, are the two brackets 25 and 26. Pivotally mounted on bracket 23 is a link 27 and opposite the link 27 and pivotally mounted on the bracket 25 is a similar link 28. In like manner at the opposite end of the suitcase there is pivotally mounted on the bracket 24 a link 30 and pivotally mounted on the bracket 26 a link 31. A bar or rod 29 extends longitudinally of the framework between the

members

12 and 16 thereof, this member extending through apertures in the

links

27, 28, 30, 31, and forming pivotal connections between the pairs of

links

27, 28 and 30, 31.

Links

27, 28, 30, 31 are made of angle stock, the base of the

angle members

27 and 30 being cut away at 32 and 33 as indicated in Figures 4 and 5 in order to permit the pivoting above-mentioned. Likewise, the bases of

members

28 and 31 are cut away as indicated at 34 and 35 in order to permit the base portion of the cooperating

member

27 or 30 as the case may be to fit against the side of these members. Pivotally mounted on the

remaining base portions

36 and 37 of the

members

28 and 31 are the

latch members

38 and 40. These latch members when in the position shown in Figure 4 permit the framework to be collapsed pivoting about the

pivots

21 and 22. At this time the

links

27, 30, 28, 31 are free to pivot about the rod 29 as well as about their pivotal connections to the

brackets

23, 25, 24, 26 so that the framework can be completely collapsed into a substantially flat condition.

When the framework has been opened as shown in 27, 28, 3t 31 about the pivots previously mentioned and thereby keeping the framework open and rigid.

Preferably all of the frame members heretofore described are of suitable strong light material such for example as aluminum or magnesium although the invention is not limited to the use of such material.

A casing generally designated 41 is provided, this casing consisting of a bottom 42,

sides

43, 44, 45 and 46, and a top 47. The bottom 42 is permanently connected as by sewing to the sides 43 through 46, it being noted that these sides are formed of a continuous piece of material having its ends joined at 43, Figure 1. The top 47 is fixed to the side 44 along one edge thereof in any suitable manner, such for example as by sewing, and the free edges of the top 47 together with the adjacent edges of the

sides

43, 45 and 46 are provided with a suitable form of closure member which, in the present instance, has been shown as a zipper fastener 56.

As is clearly shown in Figure l, the framework may be inserted within the casing 41 and after being so inserted a handle 51 may be positioned on one side 46 of the casing, the handle being fastened to the framework by means of the

machine screws

52 and 53 which extend through the handle ends, through holes in the casing side 46 and through

apertures

54 and 55 in the bar 29. A wing nut 56 is then threaded onto the screw 52 and a similar wing nut 57 threaded onto the screw 53 thereby fastening the handle securely to the framework.

In order to assure that the clothing or other articles packed in the suitcase will not come into contact with the metallic framework, the cover member has fixed thereto a plurality of lining members which fold within the assembled suitcase and overlie the frame members. Thus there is stitched or otherwise suitably fastened to the free edge of the side 43 a lining member 58 which extends over the frame member, down the side 43 of the suitcase and thence across the bottom 42. Similarly, a lining member 60 is fixed to the free edge of the side 45 and extends within the frame members down the side and thence partially across I the bottom 42. A third lining member 61 is fastened to the free edge of the side 46 and extends within the framework downwardly and thence across the bottom 42, and a fourth lining member is fixed to the top 47 at the juncture thereof with the side member 44, this fourth lining member being designated 62 and being adapted to extend within the frame member down the side 44 and thence across the bottom 42 overlying the lining member 61.

The casing 41 is preferably formed of a heavy duty textile material such for example as denim or canvas and the lining members are preferably formed of lightweight material such as cotton. It will of course be clear that both the casing and the lining members may be differently organized, while still serving their intended purposes, and that many other modifications of the invention might be made. I wish therefore to be limited not by the foregoing description but, on the contrary, solely by the claims granted to me.

What is claimed is:
