Description

Patented Jan. 7, 1947 BOTTOM SUPPORT FOR CRIBS Y Charles E; Webb, New London, Wis., assignor to Edison `Wood Products, Incorporated, West Orange, N. J., a vcorporation of New Jersey Application June 18, 1943, Serial No. 491,403 9 claims. (c1. 5-93I ri`his invention relates to cribs andmore particularly toan improved means for detachably connecting a` mattress frame to the supporting structure of a crib.

The objects of my invention are to provide simple means for detachably connecting a mattress frame to a crib supporting structure Without the use of any tools or other loose parts, which itself has no parts that need to be removed as the frame is connected and disconnected, which is operable to detachably lock the frame to `the crib supporting structure in all directions to produce arigidifying inuence on the crib structure sufficient to hold the same secure against racking, and which when the frame is disconnected may have its movable 'parts foldable substang tially into the confines of the crib components which it is adapted to interconnect so as to permit the components to be crated compactly for shipment.

These and other objects of my invention will more fully appear from the following description and the appended claims. j

In thedescription of my invention reference is had to theaccompanying drawing,` of which:

Figure l is a front elevationalI view, partly broken away, oi a `crib into which my invention is incorporated.;`

Figure 2 is a partial horizontal section taken on the line 2-7-2 of Figure 1; Y I

Figure 3 is a iront partially sectional View of the device or my invention for` connecting the mattress frameat one corner to the supporting structure of the crib, theview being to enlarged scale and taken substantially on the line 3-'3 of Figure i; and

Figure 4 is an enlarged partially sectional View of the connecting device taken on the line 4II of Figure 3.

In the figures there is shown a crib having end sections I and side panels 2. On the end sections there are mounted guide structures '3 which connect the side panels to the end sections for upand-down movement. In the present illustrative example, there are four of these guide structures at each side of the crib-ene at each corner oi' each side panel-and the guide structures are in the form of rods 3a provided with ribs 3b which space the rods from the end sections and secure the rods thereto. The end portions 2a of the top and bottom rails of the side panels are slotted to interlock slidably with the guide struc tures. To reenforce the end portions Easo that the rails willnot pull out from the guide structures, there are provided metal y U-brackets 5 which are folded upwardly from the bottom oi' the rails against the sides thereof. V

The end sections I constitute the supporting structure for a mattress frame S. T iis mattress frame may be of any suitable construction, and for illustrative purposes is herein `shown as compris` ing a rigid rectangular outer section ria and an inner `latticed, section 6b whichvis held to the` outer'section by springs 1, this being a construe tion which can be advantageously made of a nonmetallic material such as Wood. i I

The outer frame section 6a is connected to the end sections I by identical connecting devices ii provided at the four corners of the crib. These` devices` comprise vertical bracket plates @,or catchzmembers as they may be termed, which are heid by screws It) to corner posts Ia of the end sections in positions to project sidewise beu yond the` inner edges of the corner posts, the projecting portions being accordingly suitably spaced from the panels Ib of the end sections as is shown. Secured against the sides oi the outer frame section 3a by screws il are horizontal connecting members I2. These connecting members have hookedendy portions 12a which project slightly beyond the ends of the frame', there being rectangular indentations I3 in these end portions which extend down from the `top edge thereof. Pivoted to the inner end portions ci the connecting members I2, by pivot members Iii, are bracemembers I5. These brace members have hooked end portions I5a formed by providing notches I6 in the top edges of `the brace`members and rectangular indentations II in the bottom portions, the inner sides of the notches and indentations being so positioned as to be vertically in line when each brace member is in a normal position, a position for example wherein it is approximately 40 with its associated connecting member l2 as is shown in the figures. These hooked end portions of the horizontal connecting members I2 and inclined brace members I5 are adapted to engage the respective bracket` plate 9 and be interlocked therewith explained. a I p In the overhanging portions of each bracket plate 9 there is anupper hole` I8 and a lower hole I9. The upper hole Iltis made justwide enough to receive the connecting member I2, but the lower hole I9 which receives the brace member I5 is made wider than `that member and provided with an opening I9a at one side such, for example, as is shown in Figure 4. In connecting theframe B to the end sections oi the crib, the hooked endporticn i241 is rstinf as is now 3 Serted in the upper hole I8 and is then moved vertically upwardly to bring the bracket plate into engagement with the indentation I3. This interlocking engagement of the connecting member I2 with the bracket plate B, it will be observed, serves to lock the mattress frame against dispiacenient relative to the end sections I in all but a downward direction. When the connecting member I2 is in engagement with the bracket plate Si, the brace member I5 has a normal position in a vertical plane through the inner portion or the hole I9. The brace member may however be sprung sidewise from normal position to pass through the opening lea and snap into interlocking engagement with the lhole' lef Associated with the connecting member I2 is a rest IIa-which may suitably comprise allister head on one of the screws II. This rest acts as a stop for the brace member I5 when the mat-A tress frame and crib end sections are interconnected. The rest is so positioned as to require the connecting memberl I2 to be in interlocking engagement with the bracket plate 9, as is above explained, before the brace member I5 can be engaged with the bottom hole of the bracket plate. By the same token, when the mattress frame and end section I are interconnected, the rest limits the brace member I5 to a predetermined position and the latter rrnly holds the frame in a raised position wherein the connecting member I2 is in interlocking engagement with the bracket plate 9. ySince the only direction in which the brace member is not locked to the bracket plate is one at right angles to the direction in which the connecting member is not locked to the bracket plate, the mattress frame is locked to the end sections in all directions. The mattress frame may, however, be quickly unlocked from the end sections at each corner of the crib merely7 by springing the brace member I5 to the side and disengaging it from the bracket plate by way of the opening Ida, and thereupon letting the connecting member I2 fall down against the bottom edge of the upper hole I3 and then withdrawing the connecting member from the bracket plate.

It will be observed that so long as the opposite end sections I are held in parallel relation, the connecting members I2 and brace members iii will remain in stable connected relationship with l the bracket plates 9 without need for the i ia above ^-.:-.pl;i lned. When the crib is assem with the side panels, theend sections I will be so held in parallel relationship by the side panels. The rest IIa is, however, important ink strengthening the connection of the mattress frame to the end sections and, further, in maintaining the mattress frame in stable connected relationship with the end sections before the side panels are installed in the assembling of the crib.

It will be observed that the mattressy frame may be quickly connected to the supporting structure of the crib according to my invention without the use of any tools, screws, bolts or other loose parts, and that the connecting means comprises only parts which are permanently fastened to the mattress frame and crib'end seca tions. Moreover', it will be observed thattlie only substantially projecting p'art'of the conneoting means is the brace member I5, but'that this member may be folded back intol substan-e tially the confines of the mattressframe so as to permit the frame to becrate'd c'ompactly for shipment. Yetv additionally; the connecting" device serves to lock themattressframe rig-idly toI the crib end sections in all directions and thus it serves to rigidify the over-all crib structure and hold the Irame against racking. As a consequence, when the mattress frame is connected to the crib end sections according to my invention, both side panels may be movably mounted whi.e yet maintaining the crib structure rigid without the use of auxiliary supports or braces.

|ljhe embodiment of my invention herein shown and described ,will be understood to be illustrative and not necessarily limitative of my invention since the same is subject to various changes and modifications without departure from the scope of my invention, which I endeavor to exfall press according to the following claims.
