3 Claims. (Cl. 5-98) This invention relates to a combination car-bed and car-seat having a hammock in which may be placed a pad or mattress and more especially to an improved hammock construction.

Objects of the invention are to provide a hammock for such a combination bed and seat which is designed to effect a maximum of economy of material, which is of simple shape so as to be readily stitched, which is provided with means for easily attaching it to and detaching it from the frame, for example, when it becomes soiled and has to be washed, which has provision for lengthwise adjustment and provision for using the extra length when not required for that purpose for a storage pocket.

As herein illustrated the hammock has a bottom, end and side panels, the latter being foldable heightwise with reference to the bottom and stitched to afford a substantially rectangular structure having four corners. Along the top edges of the side and end walls are situated straps with one end stitched to the edges and the other foldable over the crib rails to form supporting loops by which the hammock is suspended therefrom. Fastener elements near the ends of the straps afford means for joining their ends in loop fashion. The bottom panel at one end is extended beyond the perpendiculars dropped from the top edge of the side panels at that end, the end panel at that end is inclined upwardly from the extremity of the bottom extension and the side panels have triangular extending portions joined to the edges of the bottom extension and the end panel thereby forming an internally accessible prolongation of the hammock. This end panel is foldable heightwise on itself to a vertical position and there are fastener elements at its opposite ends on the outer side engageable to hold the panel folded, thus to take up the extension and to form a pocket at that end accessible from the outside.

The invention will now be described in further detail with reference to the accompanying drawings where- Fig. l is a plan view of the pattern of the hammock prior to folding and sewing to shape for use;

Fig. 2 is a perspective view of the hammock fastened to the frame with the extension opened out for use;

Fig. 3 is a fragmentary perspective view of the extensible end of the hammock with the extension folded to form a storage pocket;

Fig. 4 is a vertical section on the line 4 4 of Fig. 2;

gig. 5 is a vertical section on the line 5-5 of Fig. 3; an

Fig. 6 is a vertical section on the line 6-6 of Fig. 2.

Referring to the drawings Fig. 1, the hammock indicated generally at 10 in its flat condition, is comprised of a suitable textile material preferably washable and includes a bottom panel 12, side panels 14, and end panels 16 and 18. Between the end panel 18 and the proximate edges of the bottom and side panels 12 and 14, at that end, there is a bottom extension 12' and triangular side extensions 14'. The bottom, side, ends, and extensions may be integral but as shown the bottom and side panels and bottom extension 12 are integral while the end panels 16 and 18 are made independently and stitched to the edges of the bottom and side panels. Preparatory to use, the panels are folded upwardly with reference to the bottom and permanently joined along their vertical and inclined edges to form a hollow box-like structure. As thus joined, one end 2,692,993 Patented Nov. 2, 1954 of the hammock will have a substantially vertical end wall 17 and the side walls 19 will be substantially vertical but the other end wall 21 will be inclined so as to form an interially accessible prolongation or pocket 23 at that end of the hammock, distendable when desired to increase the length of the hammock for a child who would be uncomfortable if confined to the distance between ends both of which were vertical. The prolongation may be taken up however when not needed by folding the end panel 18 on itself (Figs. 3 and 5) to bring its lower portion 20 into engagement with its upper portion 22 and securing them by means of fastener elements 24. When thus folded (Figs. 3 and 5) the end 21 will be vertical as is the end 17 thus shortening the hammock and at the same time forming a pocket 26 between the folds of the panel at the end of the hammock accessible from the outside thereof in which articles may be carried.

The aforesaid hammock is supported on a rigid frame (Fig. 2 of the type which may be convertible from a bed to a seat and vice versa for automobiles, the frame having side rails 30 and end rails 32), by a plurality of straps 34 and 36 which may be folded into loops and secured in this fashion over the side and end rails. The hanger loops are made independently and stitched to the edges of the hammock since continuous support is not necessary or desirable and since to out the straps integral with the hammock would be wasteful. Four .straps 34 are used along each side and one 36 at each end, these straps being made of double thickness. One end of each strap is stitched to the upper edge of the side panel or end panel, (Fig. 6), the other end is folded on itself to form a loop L. Cooperable fastener elements 40 are anchored to the straps so that when they are folded over the frame and brought together the elements may be engaged to hold the strap in loop form as shown in Fig. 2 and securely to suspend the hammock from the frame.

To afford a finished appearance, all of the exposed edges of both the hammock and the straps have piping 42 stitched thereto. As here illustrated, the stitching S (Figs. 4, 5 and 6) which is used for attaching the piping also unites the panels whose edges are concealed by the piping. In attaching the straps to the edges of the hammock, the end of each strap is matched with the inside edge of the hammock, the piping is stitched over both edges and then the strap is folded upwardly as indicated in Fig. 6. By attaching the strap to the inside so that it rises upwardly on the inside of the rails and is folded over the rails to the outside for engagement of the snap-fasteners, there is little temptation for the child to try to unsnap the fastener.

It is thus evident that the hammock may easily be attached or detached from the frame; that an economical use of the material for making the hammock is attained ,since the strap portions may be made from scrap material which would be otherwise waste; and that a hammock which may be extended, that is lengthened, for longer use is provided this extension however being constructed to be taken up when not in use to form a storage space in the form of a pocket at one end.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall Within the scope of the appended claims.

I claim:

l. A hammock bed whose eifective internal length at its top is constant but whose internal length at its lower part may be varied, said bed comprising a hammock consisting solely of flexible sheet material, the bed comprising a rigid frame from which the hammock is suspended, the frame comprising spaced, parallel side rails and spaced, parallel end rails at right angles to the side rails, the several rails being normally disposed in the same plane and defining a rectangular open structure, the hammock comprising a bottom panel of approximately the same horizontal dimensions as the open frame structure, side panels and end panels, the side panels being integral with the bottom panel, a bottom ex-`y tension element interposed between one end panel and the proximate edge of the bottom panel, each side panel 3 Y having at one end a triangular extension joined at one edge to the adjacent edge of the respective side panel, at a second edge to the bottom extension, and at a third edge to that end panel to which the bottom extension is connected, the side panels and end panels having suspension tabs at their outer edges which normally embrace the side and end rails of the frame and thereby .support the hammock, the end panel to which the bottom extension element is attached having complemental fastener elements adjacent to its inner and outer horizontal edges, the bottom extension element being in the same plane with the bottom panel when the bed is at its greatest longitudinal extension, and that end panel which is attached to the bottom extension element then inclining upwardly from the outer edge of the bottom extension element to the end rail of the frame, the bottom extension element extending vertically up from its junction with the bottom panel when the hammock is at its shorter length, and the end panel which is attached to the bottom extension element then being doubled to form a horizontal fold approximately midway its height thereby to form a pocket, said end panel being held in folded position by engagement of its upper and lower fastener elements.
