The invention relates tok childrens cribS, and has for its maj or object to vafforda practical, ehcient construction ofeconomicalmanufacture that permits the crib to be assembled or taken apart in a few seconds, without ne-v able wall has a free vand easy vertical tralvel in which any tendency toward binding or` cramping is eliminated.

Still another purpose is to afford a simple structure in which a drop side-wall caneasily be controlled by ones kneeyso that a mother while holding an infant in her arms can re-v lease the side by pressing her knee slightly inwardly; he side when thus releasedbeing perinitted to fall by gravity to-its lower-most position where it is vengaged by 'suitableresilient buffers and retained, theside being elevated again to its upper position whendesired by a free, easy motion and automatically locked in such upper position.

To these and other ends the invention-cone sists in the construction and. arrangement of parts that will appear from the following description when read in conjunction withithe.

vThe invention-comprises in general a pair of ends to which one side wall is detachably locked while the other side has .an interlocking-slidable engagement withthe ends, thus servingY to holdy `the parts: of the crib assembled while at the same time having verticaliadjustment to ione of two different positions. The structure is susceptible of difieren practical adaptations, and by way of illustration there is here shown one commercial embodiment that includes vthe ends designated at 1 and side walls 2 and 3 respectively that haveian interlocking assembly with the ends whilethe latter support and maintain a spring frame 4 provided with dowels 5, see Figures 2 and 15, engageable with openings 6 in cross-rails 7 of the ends. One of theV line 17-.11

side walls of the crib structure is held in fixed relation to the ends after being once assembled while the other side wall has a vertical sliding movement, and the foll'owing description will deal first with the side wall having a fixed relationship to the ends.

The fixed side has been designated at 2, and is illustrated in Figures 2 and 4 to 8 inclusive. It includes top and bottom rails, the top rails having vertically disposed dowel receiving openings 11 while the bottom rails are eut away at their ends, affording reduced portions 12 provided with horizontally extending dowel receiving openings 13. rlhe ends 1 have fixed thereto on their inner faces the supporting portions 14 which have upwardly extending dowels 15 at their upper ends while at the lower ends, the supports are recessed on their outer surfaces at 16 and located in said recesses are the dowels 17.

Dowels 17 engage the aforementioned openings 13 in the removable side wall and dowels 15 engage the aforementioned openings 11, as shown in Figures 4 and 5. The removable side wall is assembled by first dropping it downwardly so that the openings in the top rail engage over dowels 15 and then swinging the lower end inwardly until openings 13 engage over the dowels 17. The side wall is then locked in place by suitable locking devices such as pivoted plates 18 having notches 19 for engagement with the stops 20, see Figures to 7.

To remove the side wall just described, the locking plates 18 are swung upwardly to the position shown in Figure 6, whereupon the side wall can be separated from the ends by first swinging the lower rail outwardly and then lifting the side upwardly off the dowels 15. lVhen in place, it will be seen that the side wall 2 holds the ends at one side thereof and at the same time holds the spring frame in place, the latter being retained by the ends. The description now immediately following will deal with the other removable side wall which has locking engagement at the other side of the ends and is also permitted a vertical sliding adjustment relatively to the same.

The drop side wall has already been alluded to and designated at 3, and is provided at its ends with shoes 21 that engage around and slide on tracks 22, secured to the adjacent corner posts of the ends 1. The side wall 3 is brought into interlocking 'engagement with the ends by lifting it above the latter and then bringing it downwardly so that the shoes 21 engage over the vertical tracks 22` thereby preventing any lateral separation of the side wall and ends. The side wall 8 is adapted to be held in its normal or elevated position coinciding laterally with that of the iii-red side. 0r to be dropped to a lowered position. and the structure will now be described by which the side is held in such upper position and released when desirable to adjust it to the lower position.

26 designates a controlling rail pivotally supported by spring hinges 27 at the lower edge of the side wall, see Figure 12, and 28 designate locking plates attached at the ends of the controlling rail 26. Each locking plate 28 extends over the edge of the adjacent track 22, and includes a horizontal locking dog 29, sec Figures 9, and 12, engageable with a recess or notch 30 in the edge of the track 22 to hold the side wall in elevated position, as shown in Figure 9. This locked relation is maintained by the spring hinges 27 which actuate the controlling rail 26 and the lociing plates 28 outwardly so that the dogs 29 are held in the locking notches 30.

On its front, the controlling rail 26 is pro vided with a knee engaging or operating pui'- tion in the form of a strip 31 and by pressing on the latter and moving the controlling rail 26 inwardly, as shown in Figure 10, the 29 are moved out of the notches 3() whereupon the side is released and falls by gravity to lowermost position. Downwar-d movement of the side wall is limited by rubber buffers 82 secured at the bottom of the tracks 22, the ends of the latter being preferably bent upwardly upon themselves as at to aord means for holding the rubber buffers in place and in the path of the bottom rail of the side wall which rests upon the rubber buffers 32 when in lowered position.

34 designate metal strips attac ied to thc ends below the track 22', as shown in Figures 11 and 12, and constituting continuationsl of said tracks in order to prevent the loe ring dogs 29 from engaging under the bottoms of the tracks 22 when the side is in its lowered position. rlhe locking plates 2 8 are also provided with lugs 35 engaging behind the tracks 22 in order to impart a steady and uniformly guided movement to the controlling` rail 26 and locking plates 28. The drop side wall can be quickly lifted from its lowermost position and elevated until the dogs 29 reach and drop into the notches, whereupon the side is automatically locked in its upper position.

Figures 16 and 17 show a modification in which the locking plates are combined with the spring hinges. ln this form, the hinges 41 are located at the ends of the side wall, and each includes a lower leaf extending downwardly and formed integral with the lockingr plate as shown at 42, the latter cooperating with the tracks 22 in the same manner as already described.

lh ile the in venti on has been described with reference to certain structural details, it is not confined to the precise form an d arrangements herein shown. and this application is intended to cover such modifications or departures as may come within the intent of the improvements or the scope of the following 1 claims.

I claim:

l. In a knock-down crib, the combination with ends having vertically disposed tracks attached thereto and facing each other, 0f a side wall provided with shoes adapted to embrace and slide on the tracks and freely detachable therefrom by an upward sliding movement thereon, acontrolling rail pivoted at the lower edge of said side wall and adapted to swing inwardly thereof, and locking plates at the ends of the controlling rail having dogs adapted to lock the side wall to the tracks, the latter having recesses to receive the dogs.

2, In a crib, the combination with ends having vertically disposed tracks attached thereto and facing each other, of a side wall provided with means embracing and sliding on the tracks, a controlling rail pivoted at the lower edge ofthe side wall and adapted to swing inwardly thereof, locking plates carried at the ends of the controlling rail, each of said plates having a lug engaging the outer surface of the track so as to guide the plate thereon, and a dog movable along the outer edge of the track, the latter having a recess to receive said dog and hold the side wall in elevated position.
