Among the obj ects of the present invention are to provide an infants crib of rugged con-v struction which is readily collapsible intoa j tary assembly with the collapsed crib without distortion or excessive compression of-said 1 mattress, regardless of the construction or thickness of the latter. 7 v V Other objects are to provide a crib of the character mentioned which can be collapsed or distended with a minimum of effort, and without the need for any tools whatsoever, and which requires no removable rods, frames, or other parts that become separated from thecompleted structure either in collapsing or distending the same, and whichin use has the appearance of the familiar modern crib and involves no sacrifice of security or comfort as compared with conventional infants cribs. V i V p Another object is to provide an infants crib, the drop side of which is easily manipu lated and avoids the use of small removable latch bars, rods, springs, or the like.

. To carry outthe foregoing objects, I pro vide a crib having a fixed side frame of usual to construction, a drop side frame and end frames, the latter of collapsible construction topermit the side framesto be moved toward each other to a degreesuch as to afforda storage space therebetween in collapsed state for accommodating the mattress in fiatiundistorted upstanding position. 1 To this end I V prefer to provide a bed spring which will readily tilt upward about a hinge near one of the sidevfra mes to permitthe collapse of the crib, and to leave free the space in which the mattress is accommodated.

In a preferred construction, the end frames of the crib comprise each a fixed section rigid with the fixed'side frame, andinturning or infolding segments connected between the edges of said fixed sections, and the drop-side frame. Preferably the bed spring frame aids tomaintain distended the info-lding segments in the operative state of the crib.

In the. preferred embodiment the bed spring frame is hingedso asto tilt out of the way to permit a collapsingmovement of the i crib.- lhe spring is shown in two sections, a wider tilting section 14 attached to a narrower fixed section 14 by screws extending through elongated slots 26 and serving as hinge pins for the tilting section. A coil spring 27 is anchored to the frame 28 of the;

fixed spring section at oneend, and to the frame'29 of'the hinged springsection the other end, said spring thereby tending to tilt upward the hinged part 14 of the spring to permit collapse of the crib.

The mattress support or spring, as shown,

comprises longtitudinal strips or ribbons of;

metal, supported by coil springs anchored at the spring frame ends. i

The end parts of the frame 29 ofthe hinged spring portion exert outward pressure when in lowermost position, against the extended infolding segments 17 -18 ofthe end frames and thereby aid in maintaining the latter in distended position; For this purpose, there is preferably disposedat the lower end. of the median part of each of the end frames, a

I ments outward.

' of the anglebar.

metal camming lug '31 secured near the median hinge of the infoldingsegments at leaf 18 thereof, and having an outstanding curved tion 29 of the bed spring frame rests in operative position in an angle bar 34 connected at opposite ends to the posts 22 of the drop-side frame a little below thelevel of the rail-10. By this arrangement thespring 27 is dis tended when the framef29is' snapped into angle bar 34, and the contraction thereof upon mere release of the spring from bar 34 causes automatic upward tilting of the spring 14: r i I Any suitable latch may be provided at the angle bar 34 to lock the bed spring in operative position. I have illustratively shown a latch comprising'a horizontal slidable latch bar 37 secured by studs 38, each to ride in a longitudinal slot 39 through the horizontal web 34 of the angle bar, said latch having preferably a flange 40 riding along the'edge An upstanding spring latch tongue. ll on the latch'ibar extends through a corresponding slot42 in the angle j bar and in loeked position of the bedspring through a similar slot 43 in the lateral frame bar 29 of the'ibed spring. The latch bar has a 'downturned 'finger piece 44 by which it may be pushed tooperaltive or locking position after. thespringi has been depressed when the latch tongue will overlie the' frame of the bed spring.

In order to collapse'the er1b the finger piece .44: is simply withdrawnuntil the tongue 41 is arrested by its shoulder 45 and the bed sectionfli of the spring. Thereupon the hinged end "sections fold inward to the position shown in Fig. 5 and the bed is collapsed.

, Lockin or latching means may also be provided to 'seciire the crib in collapsed state. an illustrative embodiment shown, each of the corner posts 22 of the drop side frame carries a metallic latch bar which may be a lever 46 hinged to the corner post by a cross pin 47 therethrough. The latch level has a relatively short outer finger. operating end 48 at one'end and the longer l'atcharm46 at its inner end. In the collapsedstate: of the crib, as shownin Fig. 5, the latch bars'are depressed, so that the latching tongues 50v at the free extremity thereof extend into corresponding latching slots 51 in the'fixed sections 16 of the end frames, thereby retaining the crib securely locked in collapsed state.

In extended condition, as'best shown in Figs. 1: and 2, the latch arins46 similarly coact with latching slots 52 in the contiguous infolding'end frame segment 18. A groove 53 of the thickness oft-he latching arm. 46 is preferably provided in the upper edge of the end frame segment to accommodate the width of said arm so that the same in'la-tched condition comes flush with the upper edge of the crib; v

To better reveal the-details of the construction I have shown a crib with relatively thick posts, rails, and struts. at will be understood that the invention is adapted and preferably employed in constructions embodying parts of metal, considerably thinner than those shown andtl1e1'eby afi'ording in collapsed state an even more'compact structure than that shown. The term side fra ne-and fend frame is inclusive of panel constructions such as are employed in in fants cribs, which panels may readily be employed to advantage in my construction.

'lhefixed end frame sections 16 preferably determine awidth no greater than the thickest mattress employed with a.crib, iso'th at in collapsed state of the crib, the mattress would be laterally contacted by t-he'fixed side frame 10 at one face and'by the tilting spring area l t at the other, its lower edge resting upon the narrow fixedspring section] 14 Thus, the crib in collapsed state'together with the mattress and the'inetal strip support therefor-can be handled as'a single unit,.a nd

to this end themattress need not be of any special limber or thin construction and does not'suffer any distortion or twisting in positioning the-same in the eollapsedcrib.

:Ihe collapsed crib, it willbeseen, is a stable construction, standing on its four posts, taking up littleroom, andis very convenient to handle. The mattress is well protected in elevated position away from the floor or wall, so that it will not becomeinjured or soiled.

I have also shown a special construction of drop side for the crib, which is of more general application to infants cribs, whether of collapsing or non-collapsing type. Ihave particularly shown a drop side construction, which provides no detachable latches, rods, screws, or springs, but is a simple unitary construction.

In the embodiment illustratively shown, the ends of the drop sides are lateral metal strips 60' bent at their ends over the upper and lower rails of the drop side to which they are secured by screws 62. Each of the metal strips 60 has a pair of runner studs 64 respectively near the upper end and near the lower end thereof. The runnerstuds ride in corresponding runways which may be runner slots 65 preferably extending longitudinally of metal guide rails 66 secured to the drop side posts 22. Each of these guide rails, as shown, constitutes one of theweb's of a metal angle bar theother web of which is secured as by screws 68 to the end posts. A tongue 69 at the end of web 67 may be turned over the top of the corner post for greater security and protection. The web 67 of each angle bar runner rail is secured to the corner post as best shown in Fig. 3 to afiord a space 70 between the runner rail and the contiguous surface of the corner post wherein ride the runner studs 64 of the drop side. The heads of the runner studs being wider than'the runner slot 65, it will beunderstood that preferably the lateral strip 60 of the drop side and the runner rail 66 are preassembled by means of the runner studs 64, the shank of whichis preferably upset at 71 upon the lateral strip.

The upper end of each runner slot is reyersely bent or hook-shaped at 72 from which it will be apparent that when the drop side is raised to its upper limit and then pushed inward, the upper runner studs 64 will lock or hang the drop side in upper or closed position, from said upper end. Preferably the.

lower ends of the runner slots 65 terminate slightly above'the floor, so that the lower of the studs 64 will'rest thereaga-inst for sustaining the drop side in lower position. In order to lower the drop side from closed position, it will be understood that the same is first raised to its limit and drawn outward, so as to cause the runner studs 64 to clear the or in the store room of a hotelas well as in transportation, and Which maintains the mattress in protected, clean and inviting condilapsed in the daytime and to distend it only atsuch timeswhen it is actually-to be used.

I claim:

A collapsible crib including side frames and an end frame, each of the end frames including a stationary sect-ion rigidly connected to one of the side frames and a plurality of inwardly hinging sections connecting said stationary section to the other side frame, a spring constituting thebottom of'the crib and including a pair of hinged sections, the narrower of which is approximately equal in width to the thickness of the mattress and of slightly less width than the stationary end frame sect-ions, thewider section of the spring being foldable upwardly intofvertical position and when in such' position cooperating with the other springsection, the stationary end sections and one side wall section to de fine an open topped elongated narrow boxlike structure for supporting the mattresson edge, the spring side of such structure being out of the path of inward folding movement of the hinged end frame sections whereby the latter maybe folded inwardly into-substair' tial parallelism with the upwardly swung spring section, latches carried by the other Y side section of the crib, keeper means for the latches on certain of the hinged end frame sections, said latches being operative to hold the end frame sections against inward swinglapsed position with the latches engaging said last mentioned keepers.

reversely turned end 72 to the runner slot 65,

whereupon the drop side can be eased downward.

Thus I have provided an infants crib, which in collapsed state affords considerable l space economy while stored in the warehouse,
