Gilliam FOLDABLE BABY CRIB BACKGROUND OF THE INVENTION This invention relates to a foldable baby crib and more particularly to a foldable baby crib having advantageous operating features, with these features facilitating a desirable appearance.

The frequent need for moving baby beds, play pens, and the like from place to place has led to the availability of a number of different collapsible baby beds. Many of these products are provided with a number of mechanical features rendering the same complicated, utilitarian, and unlike the conventional baby crib in function and appearance. Thus, many prior foldable devices are disproportionate for the sake of attaining collapsibility, and usually are not provided with slidable sides which can be moved downwardly out of the way when baby care is necessary from the side of the crib. These constructions are not well adapted for the baby crib which is to be moved occasionally, but which is normally called upon for conventional crib use.

SUMMARY OF THE INVENTION According to the present invention, a collapsible baby crib includes a mattress supporting frame having collapsible legs as well as foldable head and foot boards at either end thereof. Crib sides, which normally extend upwardly from the frame, have articulated connections therewith providing vertical sliding movement for each side relative to the frame as well as pivotal movement of the sides over the frame. The sides are normally engageable with hook means provided on the head and foot boards when the sides are vertically upraised. The sides may also be slid upwardly and pivoted over the mattress for disposition in juxtaposed relation with each other and with the mattress, after which the head and foot boards can be closed thereover. Alternatively, the sides may be slid downwardly providing access to the mattress from the side thereof.

The crib constructed in this manner functions in substantially the same manner as a conventional nonfoldable crib. It also has the appearance of a conventional crib and is therefore an acceptable piece of furniture for home use. However, the crib, together with mattress, can be folded into a completely flat package for ready transportation from place to place. This convertability to a flat configuration does not require any mechanical disassembly of the crib parts.

It is an object of the present invention to provide an improved foldable baby crib.

It is another object of the present invention to provide an improved foldable baby crib which functions during normal operation in a manner similar to conventional non-foldable cribs.

It is another object of the present invention to provide an improved foldable baby crib which is proportioned in a manner similar to the usual non-foldable baby crib..

It is another object of the present invention to provide an improved baby crib with sides which are not only foldable inwardly over the mattress, but which are also slidable downwardly for providing access from the side of the crib.

The subject matter which I regard as my invention is particularly pointed out and distinctly claimed in the concluding portion of this specification. The invention,

however, both as to organization and method of operation, together with further advantages and objects thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings wherein like reference characters refer to like elements.

DETAILED DESCRIPTION Referring to the drawings, the foldable crib according to the present invention comprises a frame including a base 10, suitably formed of a relatively thick, flat plywood panel and

base ends

12 and 14 secured thereto in upright position by means of wood screws, steel angle brackets, or the like. A mattress 11 is positioned on top of base 10. At the top edges of base ends 12 and 14, a head board 16 and a foot board 18 are respectively hingedly connected by means of piano hinges l9 and 20 while at the lower edges of the base ends,

foldable legs

22 and 24 are hingedly secured. The legs may alternatively be joined to the base itself. The legs may be provided in pairs at the head end and foot end of the crib, such pairs being structurally joined together by bracing means (not shown). Toggle

braces

26 and 28, disposed between the legs and base 10, normally support the legs in a vertical position, but when pivoted these braces allow the folding of the legs underneath base 10 as illustrated at 22' and 24, respectively.

The crib is also provided with slatted

sides

30 and 32, with side 30 located in the foreground of FIG. 1. The sides normally extend upwardly from the frame, i.e. upwardly from base 10, having an articulated connection therewith providing vertical sliding movement for each side relative to the frame, as well as pivotal movement of the sides over the frame. This connection is more clearly illustrated in FIGS. 4 and 5, and includes a vertically disposed metal bracket 34 secured to vertical end piece 36 of base end 14 by means of wood screws 38. The bracket 34 is provided with a vertical slot 40 which is open at its lower end, but which is concluded at its upper end by stop 42. Bracket 34 is substantially U- shaped in cross section as illustrated in FIG. 5 with the slot 40 disposed at the bottom of the U, for thereby enclosing a channel 47 between bracket 34 and member 36. The adjacent lower corner of side 30 is provided with a rectangular metal sleeve 44 secured over the end of the lower horizontal slat of the side 30. This sleeve carries a metal tongue 46 adapted to be slidably received, vertically upwardly in slot 40 of bracket 34, between the bracket and the end piece 36 of base end 14. The tongue is joined to sleeve 44 by means of round shank 48 passing through slot 40. The cross-sectional relationship is as illustrated in FIG. 5. It is understood that a similar articulated connection including a slotted bracket 34 is provided at each lower corner of each crib side between the respective crib sides and

base ends

12 and 14.

Let us assume side 30 has been engaged by slotted brackets 34 on the foreground side of the crib in FIG. 1, and it is desired that side 30 be secured in a normal, substantially vertical position. The side 30 is upraised to a position indicated in dashed lines at 30, with lower tongues 46 sliding along slots 40 in slotted brackets 34. The upper corners of side 30 are now engageable with hook means provided adjacent the upper corners of the sides. One such hook means is illustrated in FIG. 6 and is disposed on the inner side of foot board 18, that is, on the side facing head board 16 and immediately above slotted bracket 34 on member 36. This hook means comprises a bracket 49 secured to foot board 18 with wood screws 51 and provided with a vertical top opening slot 50 which concludes at a lower stop 52. Slot 50 receives a mating means comprising a tongue 54 joined to rectangular sleeve 56 with shank 58. Sleeve 56 is in turn secured over the end of the upper horizontal slot of side 30. Thus, when side 30 is raised to the position illustrated in dashed lines at 30' in FIG. 1, the tongue 54 is lowerable into slot 50 until shank 58 rests against stop 52, with tongue 54 being located between bracket 49 and foot board 18. The cross section is U-shaped, similar to that illustrated in FIG. 5 with respect to the previously mentioned slotted bracket 34. As tongue 54 slides downwardly within slot 50 of bracket 49, the lower tongue 46 slides downwardly inside bracket 34.

It is understood that a similar upper corner hook means construction is located at each of the upper four corners of the crib, that is, on the upper inside wall of the head board and on the upper inside wall of the foot board. The bracket constructions are horizontally juxtaposed such that a side, for example side 30, will rest with a shank 58 against a lower stop 52 of a bracket 49 at each upper end of side 30, with the side 30 thereby secured in an upright position. It is understood that latching means may be provided across the tops of slots 50 in brackets 49, if desired, in order to lock the side in position.

It is observed that when the side 30 is in upright secured relation relative to the crib head board and foot board as just described, the lower portion of side 30 slides below the top level of mattress l 1 whereby an infant is protected from wedging an arm or leg between the mattress and the lower edge of side 30.

In order to acquire access to the side of the crib, i.e. in order to provide normal infant care upon the crib mattress, a side 30 may be lowered downwardly. This is accomplished by first raising side 30, e.g. to the position illustrated at 30' in FIG. 1, such that tongues 54 clear the tops of slotted brackets 49. Then, the top of side 30 is moved slightly outwardly away from the crib to clear brackets 49 and the side is dropped. At this time, tongues 46 at the lower corners of side 30 drop from slots 40 in slotted members 34. With the side 30 dropped vertically to the floor, the top edge thereof will be on a level just above the mattress 11 providing ready access to the mattress surface, but with a short portion of the crib side extending to a level just above the mattress level. When the required access is no longer needed, side 30 is once again raised, while positioning tongues 46 enter slots 40 at each end of the crib. The side is then further raised until tongues 54 are above the tops of slots 50, allowing downward insertion of tongues 54 into hooked relation with slots 50 as hereinbefore described. The upper stop 42 of each bracket 34 is positioned such that the side 30 can be moved high enough for entry of tongues 54 into slot 50.

While the above operations have been described in particular connection with side 30, it is understood that a side32 on the opposite side of the crib is substantially identical and operates in the same manner.

The crib according to the present invention is foldable into a flat package by first folding sides 30 and 32 over mattress 11. It has been noted that, in normal vertically secured position, the lower edge of side 30, for example, is below the top surface of mattress 1 1. However, as has also been noted, side 30 is raisable upward from this position. For folding, side 30 is first raised upwardly until tongues 54 clear slots 50 and brackets 49, and the side is then pivoted into a horizontal position on top of mattress l 1. At this time, the tongues 46 will slide nearly to the top of slots 40. The

sides

30 and 32 have a height approximately or nearly equal to the width of the crib, so that with the sides in horizontal position, they extend nearly across the crib. This is not a necessary requirement, but provides ample height for each crib side for giving'the desired confining enclosure to the infant when the crib sides are vertical, with ample storage room for the sides when folded over the mattress. This construction can be distinguished from foldable crib arrangements wherein the cribsides are foreshortened vertically in order to fit within a smaller space when folded. It is noted that as the crib side 30 folds over the mattress, the lower edge thereof rises to the top level of the mattress as permitted by the sliding action of tongues 46 in slots 40.

After side 30 has been folded to a horizontal position, side 32 is folded from the opposite direction over side 30 and the mattress as illustrated in FIGS. 2 and 3. Side 32 similarly extends nearly across the top of the crib. Since side 32 folds on top of side 30, the tongues 46 associated therewith will rise further in corresponding slots 40, usually against Y the upper stops 42. Of course, the abutment against the stops 42 is not a requirement, inasmuch as the slotted brackets 34and base ends 12 and 14 can be made somewhat longer. However, it is generally desirable that base ends 12 and 14 not be much higher than the mattress. Therefore, it is convenient to provide a height thereof sufficient for providing space for brackets 34 just accommodating the tongues 46 of side 32 in a horizontal position. The stops 42 prevent the side from leaving a pivotally anchored condition, and in general secures the crib sides during transport thereof. While in the present example side 32 is illustrated as foldable upon side 30, it is clearly understood that the reverse operation may take place with the slotted members 34 accommodating the reversed slidable juxtaposed positioning of the two

sides

30 and 32. Therefore, the folding operation of the crib is easily accomplished without having to follow a particular procedure in folding down the sides.

After the sides are folded as illustrated in FIG. 2, the head board 16 and the foot board 18 are also folded over the sides. The foot board 18 is illustrated in folded position in FIG. 2, and it can be seen that head board 16 is foldable down to a position illustrated in dashed lines at 16. The combined height of the head board and foot board is slightly less than the overall length of the crib so that the head board and foot board do not interfere with one another when folded down. Nevertheless, the head and foot boards extend in their vertical positions to a height commensurate with the height of

sides

30 and 32.

FIG. 3 illustrates the crib in a completely folded condition, and also illustrates

legs

22 and 24 as folded underneath base 10. It is seen that the head and

foot boards

16 and 18 protect the upper surface of the mattress as well as

sides

30 and 32 when the head and foot boards are thus folded. The crib as illustrated in FIG. 3 is easily transportable from place to place, but may be quickly set up wherever desired.

It should also be noted that the appearance of the crib as illustrated in FIG. 1 is comparable to the usual appearance of a crib. That is, the

sides

30 and 32 are high, providing optimum enclosure, even though these sides are easily accommodated when the crib is collapsed. Moreover, the

sides

30 and 32 in their vertically secured positions extend below the top level of mattress 11. The proportions of the crib are in general the same as those found most advantageous in the usual non-portable crib. Furthermore, either side 30 or side 32 can be dropped, as hereinbefore described, so that ample access can be had to the crib mattress area.

While I have shown and described a preferred embodiment of my invention, it will be apparent to those' a side receivable between said head and foot boards and provided at its ends with longitudinally disposed tongue members near its four corners, a first pair of slotted brackets attached to said frame near lower ends of said head and foot boards for receiving tongue members attached to the said side near the lower corners thereof, said slotted brackets having vertical, downwardly opening slots receiving the last mentioned tongue members, and having upper stops, said slotted brackets being located directly opposite one another upon facing surfaces of base ends of the frame, a second pair of slotted brackets attached to said frame upon head and foot boards, respectively, directly above the first mentioned pair of slotted brackets and opposite one another upon the surfaces of the head and foot boards that normally face one another, the second pair of slotted brackets receiving the tongue members attached to said side near the u per orners thereof the second air of slotte brac ets having vertical slots whlc open upwardly for receiving the last mentioned tongue members, and having stops at the lower ends of the last mentioned slots,
