A. T. DAVID Filed D66. 17, 1946 INFANT'S CRIB CONSTRUCTION HAVING A REMOVABLE FLOOR Jan. 2, 1 951 Patented Jan. 2, 1951 INFANTS CRIB CONSTRUCTION HAVING A REMOVABLE FLOOR Allan T. David, Corona, Calif. Application December 17, 1946, Serial No. 716,845
This invention relates to an infants crib, playpen or the like and is particularly directed to an improved form of support for a fabric sling extending between parallel sides of such device.
The principal object of this invention is to provide a removable fabric support sling for a crib, play-pen or the like, which is maintained in place by keeper bars positioned outside of the crib and passing through loops provided on the support sling.
Another object is to provide a structure of this type having parallel non-folding sides separated by parallel foldable sides, in which the loops on the fabric sling and the keeper bars extend along the non-folding sides, whereby the foldable sides in their operative position may tension the sling against excessive sagging.
A further object is to provide an improved mounting for a fabric support sling on parallel rows of spaced vertical bars forming the sides of a. crib, playpen or the like, which includes a plurality of loops on the sling extending through spaces between the bars and maintained in position by a removable keeper rod outside of the bars.
Other objects and advantages will appear hereinafter.
In the drawings:
Figure 1 is a perspective view, showing a, collapsible crib for an infant and incorporating a preferred embodiment of my invention, the device being shown in collapsed position;
Figure 2 is a perspective view of the crib in its operative position;
Figure 3 is a sectional plan view, partly broken away, taken substantially on the line 3--3, as shown in Figure 2.
Referring to the drawings, a folding crib structure, generally designated I ll, may include parallel non-folding sides ll and i2, which are connected by hinges it to the foldable sides or ends 14 and I5. The sides II and i2 and ends I; and I5 may be defined by parallel rows of vertical spaced bars IE. The top rails of the sides and ends form a frame l1, receiving the upper ends of each of the bars It in fixed relation. Similarly, the lower rails on the sides and ends constitute a frame l3, which receives the lower ends of the bars It in fixed relation. If desired, the bars It may take the form of dowel rods, which are fixed into spaced holes provided in the upper frame I! and lower frame Ill. The foldable sides or ends l4 and I5 are provided with hinges I9 which, in cooperation with the hinges it, permit the crib to be collapsed to the position illustrated in Figure In accordance with my invention, a sheet of flexible material, such as canvas, cloth, or other natural or synthetic fabric, provides a support sling 29, which extends horizontally between the sides H and I2. This support sling 2?} may take the form of a continuous loop of fabric or may comprise a single sheet having individual loops 2i formed along its opposed edges. Notches or gaps 22 are provided between adjacent loops 2i for reception of the individual bars 13 on the sides ii and 12. 'It may be found desirable to reinforce the loops with additional thicknesses of material. The loops 2| extend outwardly between spaces between the bars as and a continuous keeper rod 23 is axially inserted through all of the loops on one side of the support sling 20.
Means are provided for supporting the fabric sling Eli and keeper bars 23 against gravity and,
as shown in the drawings, this means includes an intermediate support frame '24 having parallel sides and ends connected by the hinges 25. Additional hinges 25 are provided centrally of the end members or the intermediate frame 24, so that the frame 25 folds in an exactly similar manner with the upper and lower frames ll. and i8. Holes 27! are provided in the frame 24 for sliding reception of the vertical bars It to permit the frame 26 to be mounted at any desired elevation between the frames ll and I18. Any suitable or desirable means may be provided for securing the intermediate frame 24 on the rod H5 at the desired elevation and, as shown in the drawings, this means may include a plurality of screws 23 for fastening the frame 2 1 to the rods IS.
The fabric support sling 2!] may be easily removed by withdrawing the keeper bars 23. If desired, a pair of such support slings may be kept on hand for a single crib in order that one may be in service while the other is being cleaned.
The support sling 28 may be easily installed when the crib is partially collapsed. The loops 2! on one side of the sling 20 are passed through openings between the bars 15 on one of the sides and the corresponding keeper rod 23 is passed through the loops to prevent disassembly. The other side of the support sling is then secured to the bar I 5 on the other side of the crib in a similar manner. The foldable sides 14 and i5 are then moved to operative position, as shown in Figure 2. This action tensions the support sling 28 to minimize undesirable sag.
Any convenient form of pivoted latch 29 may be provided on the sides or ends I i and I5 to maintain them in the extended operativ position and prevent them from collapsing.
The infant may be' placed directly on the surface of the sling 26 or the sling may be employed simply as a mattress support.
For a small baby, the intermediate frame 24 may be positioned at a relatively high elevation on the bars [6, so that the baby may be easily reached. As the infant grows, it may be desirable to lower the intermediate support 24 on the rod 56 to avoid danger of the infant falling from the crib and yet be supported at a convenient elevation.
A further feature of this invention lies in the construction wherein the support sling 263 may be carried either above or below the intermediate frame 24 so that, upon inverting the entire crib structure, the child may be supported at either a low elevation or high elevation, as desired.
Having fully described my invention, it is to be understood that I do not Wish to be limited to the details herein set forth, but my invention is of the full scope of the appended claims.
1. An infants crib, play-pen or the like having a side defined by a row of spaced vertical bar elements, top and bottom horizontal members at 'oppose'd ends of the bar elements adapted to maintain the bar elements in position, an intermediate horizontal member fixed relative to the vertical bar elements and positioned between the top and bottom members, a fabric support sling, a'plurality of loops on the sling extending outwardly through the spaces between adjacent bar elements, and a continuous keeper rod extending through the loops outside the vertical bar elements and supported by said intermediate horizontal member.
2. An infants crib, play-pen or the like having parallel'sides defined by two rows of spaced vertical bar, elements, top and bottom frames at keeper rod extendingthrough the loops outside the vertical bar elements and supported by the intermediate frame.
