2 claims.

The present invention relates to a portable baby crib or an equivalent bed construction and has reference in particular to a structure in which the component parts are especially designed and coordinated for folding, whereby to thus provide a crib which may be readily set up for use and just as readily knocked down and folded into compact and convenient form for transportation, if and when needed.

In carrying out the principles of the invention, I have evolved and produced a simple and economical structure possessed of facilities and advantages found in regulation and standard type cribs and which has the added advantages of portability vand expediency attending the knockdown, folding, and subsequent erecting steps.

Another object of the invention resides in the provision of a foldable crib in which the longitudinal occupant confining sides or walls are liftable and lowerable and are of sectional construction, adjacent ends of the respective wall sections being connectible with each other when the crib is set up for use and foldable against the head and foot sections when compactly folded for convenient handling and transportation and storage requirements.

Novelty is also predicated upon the aforementioned sectional drop sides or walls for action in conjunction with a mattress supporting spring,

the latter embodying sections hinged to the head and foot and hingedly connected together to allow for expeditious and compact folding.

A further and advantageous phase of the invention has to do with the adoption and use of a sectional mattress, the sections of the mattress being connected together by a slide fastener of the zipper type, this so that the mattress sections may be brought close together and lodged between the head Iand foot and in intimate relation with the other folded parts between said head and foot.

Other and more specific features and advantages of the invention will become more readily apparent from the following description and accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure l is a top plan view of the crib or bed set up for use, the mattress being omitted for clearness of illustration of the other parts.

Figure 2 is a side elevational view of the structure seen in Figure 1, this view showing one of the drop-sides lowered, in dotted lines, to a down position.

Figure 3 is an exterior end view of the crib with the detachable base board or panel attached.

Figure 4 is a perspective View which serves to illustrate the interior side of either head or foot, this to bring out the construction of the detachable base board.

Figure 5 is an enlarged fragmentary sectional view showing details embodied in the sectional hingedly mounted liftable and lowerable side walls.

Figure 6 is an edge elevational view showing the structure in partially folded form.

Figure 'iris a view showing the structure completely folded with the sections of the mattress embodied.

Figure 8 is a top plan view of one end of the structure showing the manner in which the adjacent sections of the vertical side walls are folded into compact form.

Figure 9 is a view like Figure 7 with the mattress sections removed and with the rest of the structure folded into tightly compacted form.

Figure l0 is a slightly enlarged view taken transversely through the central portion of the so-called spring with the spring means removed. this view being what is seen by observing Figure l1 from either left to right or right to left, and

Figure ll is an enlarged fragmentary view of the central portion of the spring.

By way of introduction to the detailed description, it is to be pointed out that the head and footl of the bed or crib are the same in construction insofar as the makeup of each is concerned. However, for purposes of differentiation the head is denoted by the numeral I4 (Figs. l and 2) and the foot by the numeral l5. Reference being had to the details of construction in Figures 3 and 4, it will be noted that each part has its upper rail provided with a hand-hole i6 which, incidentally, is usable to accommodate a rope or the like (not shown) which may be used in tying the head and foot together when the structure is folded as seen in Figures 7 and 9. The vertical members Il are provided with L-shaped rods I8, the upper portions having keeper notches I9 which serve a purpose to be hereinafter described. The lower ends are suitably stabilized and mounted in assembling fixtures 2i) secured to the lower ends of said members Il. I also direct attention to l.-

shaped brackets 2| which serve in a manner to be hereinafter described. The detachable skirt or base section comprises a base board or panel 22 having its ends mounted in grooves formed in the posts'23 and held detachably in place by assembling hooks 24 engageable with fixed retaining pins (see Fig. 3). The lower ends of the posts are provided with casters 2B while the upper ends are provided with dowels 21 which fit removably into sockets provided in the lower ends of the members Il, as is obvious. It is understood that the crib, as a unit, is usable with and without the leg equipped base board. That is to say, the latter board or panel 22 is applied or removed according to needs and lequirements.

Each confining wall or drop-side is the same in construction and the description of one will suffice for both. It follows, therefore, that each side Wallis made up of

openwork companion sections

28 and 29. These sections are respectively mounted to hinge and slide on the aforementioned rods I3. They are also provided with latch pins 30 (see Fig. 5) engageable in endless annular grooves functioning as appropriate keeper seats I9. The latches are provided with knob equipped linger-grips 3| to facilitate projection and retraction, asis obvious. When projected as seen in Figure 5, the sides are held up in the, full line position shown in Figure 2. By releasing the latches the side may be dropped down to the dotted line position here shown. It will be noted too that the endless form of the. keeper seat or channels allows the sections to fold inwardly and into overlapping relation while the latches are still engaged. Further, the sectionsv 29 are provided with suitable coupling clips, 32 and each clip is in turn, provided with a screw-threaded socket 33 which fits into a boreV provided therefor in the co-acting rail of the section 23. A thumb-screw 34 is threaded into place through the bore and into thesocket 33,l this in a manner to separably adjoin4 the rail' portions of the

respective sections

28 and 29. By removing the thumb-screws (it being necessary to. use four for stability), the sections. are then free to swing and may be folded against the head and foot sections as brought inA the drawings, particularly7 Figures 6 to 9. inclusive.` Taking up now the crib bottom, this may be generally referred to as the mattress spring It comprises complemental sections 3'5 and 36 hingedly mounted at their outer ends, as at 3T, in the supporting, and assembling brackets 2i. The frames ofy the respective sections are of angle-iron construction as shown in Figure 10 and the longitudinal and transverse wires are connected to the end members of the frames by customary coiled springs 38 as shown in Figure 1, The longitudinal sidewires are anchored by diagonal or slanting coiled springs, these being employedv to allow sufdcient freedom and play to accommodateV the sections 4U' and 4I of the sectional mattress; The spring equipped wires are hingedly linked togethervr for proper folding,A this in any suitable manner as generally denoted by the numeral 42 inA Figure i. The adjacent, ends of the angle-irons of the re'- spective sections and' 36 are hingedly connected to` L-brackets 43,. the pivots being denoted at 44. The brackets 43 on the respective sides of the spring are connected by the. rein-forcing rod or truss 45, as shown in Figures 10. andi 11. Thus, the frame parts of the spring are hinged tc the head and foot of the bed and-hingedly-connected together and the spring means is such as to accommodate the hinging and folding steps.

As before stated, the mattress is made. up. of the complemental sections or halves;A 4i); and 41| and these are interconnected b-y---al slide,- fastener means of the zipper type. This allows; the

mattress sections to be folded in with the rest of the structure as shown in Figure 7. The flexibility of the coiled springs 2S permits proper distortion of the spring anchored wires to allow the mattress sections to be compactly lodged in place in the respective positions illustrated in Figure 7.

The preceding detailed description referring to parts by distinguishing reference numerals seems to comprehensively cover the features and parts in an orderly manner. The drawings show the crib set up for use and also knocked down and folded for transportation. In addition, the drawings in Figures 3 and 4, bring out the fact that the base panels 22 and their associated caster equipped legs 23 may be detached to decrease the dimensions of the crib so that it may be carried on the rear seat of an automobile in setup form. It is obvious that the crib or bed herein shown and described constitutes a structure possessed of requisite parts and refinements susceptible of fulfilling my aims and in particular, the principal object of the invention which is to provide a compact and convenient knock-down and foldable crib for expedient handling and transportation.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.

I claim as my invention:
