' FOLDABLE AND PORTABLE ENCLOSURE Filed June l2, l1957 2 Sheets-Sheet 2 ,means of paper adhesive tapes United States Patent 2,878,488 FOLDABLE AND PGRTABLE ENCLGSURE John F. Doskocil, St. Louis, Mo. Application June 12, 1957, Serial No. 665,215 6 Claims. (Cl. 4-177) This invention relates to foldable and portable enclosures, and more particularly to such an enclosure adapted for use as an infants crib, a play pen, a bathinette, a wading pool or the like.
Among the several objects of theinvention may be noted the provision of a foldable and portable enclosure of the class described which is economical to manufacture; the provision of an enclosure of this class adapted to fold into a compact flat package so that it may be conveniently carried and stored; the provision of an enclosure of this cla-ss which comprises a foldable frame which may be made of an inexpensive material such as paper board and a basket which may be made of waterproof material such as exible sheet plastic material, the basket having strong watertight seams; and the provision of an enclosure of this class which is easy to erect for use. Other objects and features will be in partv apparent and in part pointed out hereinafter.
The invention accordingly compri-ses the constructions hereinafter described, the scope of the invention being indicated in the following claims.
In the accompanying drawings, in which one of various possible embodiments of the invention is illustrated,
Fig. 1 is a perspective of an enclosure of this invention as it appears when erected;
Fig. 2 is an enlarged longitudinal vertical cross section of the erected enclosure, taken on line 2-2 of Fig. 1, with parts broken away;
Fig. 3 is an enlarged transverse vertical cross section of the erected enclosure, taken on line 3-3 of `Fig. 1;
Fig. 4 is a perspective of the frame per se of the enclosure as it appears when collapsed;
Fig. 5 is a plan of the blank from which the basket of the enclosure is made;
Fig. 6 is a plan of the frame per se, showing in solid lines how the frame appears when erected, and showing in dotted lines how the frame is collapsed; and,
Fig. 7 is a detail perspective showing a basket seam.
Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.
Referring to the drawings, a foldable and portable enclosure of this invention is shown to comprise a foldable frame l. This consists of two generally identical strips of stiff paper board each designated 3. Each strip is scored on two transverse lines 5 and 7 which in effect divide it into three panels, an intermediate panel 9 and outer panels 11 and 13. The outer panels 11 and 13, which are at least approximately the same length, are shorter than the intermediate panel 9. The end of panel 11 of one strip 3 is abutted against and hingedly connected to the end of panel 11 of the other strip 3 by means of paper adhesive tapes 15, and the end of panel 13 of the one strip 3 is abutted against and hingedly connected to the end of panel 13 of the other strip 3 by also designated 15. This hinges panels 11 together at 17 and hinges panels 13 together at 19.
The frame 1 constituted by the two strips 3 (scored on lines 5 and 7 and having'their ends hingedly connected at 17 and 19) is adapted to be opened by folding on lines 5 and 7 and at hinge lines 17 and 19 to the open rectangular form in which it is illustrated in solid lines in Fig. 6. As the frame is so opened, panels 11 of the two strips are aligned end-to-end and constitute one side wall of the open rectangular frame, panels 13 of the two strips are aligned end-to-end and constitute the other side wall of the open rectangular frame, and panels 9 of the two strips constitute the end walls of the open rectangular frame. These frame end and side walls are hingedly connected where they meet at the corners of the open rectangular frame by reason of the score lines 5 and 7. The frame 1 is foldable from the open rec tangular condition to the compact hat condition in which it is illustrated in Fig. 4 by folding panels 11 inward on score lines 5 toward panels 13 and folding panels 13 inward on score lines 7 toward panels 11, as illustrated in dotted lines in Fig. 6, in such manner that panels 11 fold flat against one another and panels 13 fold at against one another (and against the flat-folded panels 11), with one end panel 9 collapsed flat against one panel 11 and the other end panel 9 collapsed dat against one panel 13.
The foldable and portable enclosure further comprises a basket generally designated 21. As hereinillus'- trated, this is formed from a blank (see Fig. 5) of a heatsealable iiexible sheet plastic material, such as polyethylene, having a central rectangular portion 23, ap portions 25 projecting at the ends of the central rectangu lar portion, and flap portions 27 projecting at the sides of the rectangular portion, so that the blank is of cruciform shape. The width of each ap portion is generally twice the width of the strips 3 of the frame 1.
The end flap portions 25 are folded on lines 29 at the ends of the central rectangular portion 23 to lie generally at right angles to the central rectangular portion and the side ap portions 27 are folded on lines 31 at the sides of the central rectangular portion to lie generally at right angles to the central rectangular portion 25 and to bring the end edges of the aps together. E nd marginal portions 33 of the end flaps 25 are doubled over on lines 35 to lie on the outside of the end flaps and provide double-thickness portions, and end marginal portions 37 of the side flaps are folded around on lines 39 and lapped on the outside of portions 33. The lapped margins 37 are then heat-sealed to the double-thickness portions throughout their lengths as indicated at 41. The double-thickness portions also become heat-sealed together.
These operations convert the blank shown in Fig. 5 to the form of a rectangular basket, the bottom of which is constituted by the central rectangular portion 23 of the blank, the ends of which are constituted -by the ilaps 25 and the sides of which are constituted by the flaps 27, with heat-sealed seams 41 at the four corners of the basket. These seams are reinforced seams by reason of the folding over of portions 33 of the flaps 25. The dimensions of the blank are such that the rectangular bottom portion 23 of the basket is slightly smaller than the frame 1 when in its open rectangular condition and the sides and ends of the basket are approximately twice as high as the width (or height) of the strips 3 which constitute the frame 1.
The frame 1 is opened to its open rectangular condition illustrated in solid lines in Fig. 6, and the basket 21 is placed within the frame. The bottom 23 of the basket is located in the plane of the bottom edge of the frame 1 and portions of the ends 25 and sides 27 of the basket are folded down and around the upper edges of the sides and ends of the frame on lines 43 and 45 to lie on the outside aardgas of the frame (see Figs. 1-3). As a result, inside end panels designated 25a of the .basket 21 extend on the inside of end walls 9 of the frame generally at right angles to central rectangular portion 23 and inside side panels designated 27a extend onthe inside of side walls 11 and 13 of the frame generally at right angles to central rectangular portion 23. Also, outside end panels designated 25b which are integrally joined to inside end panels 25a at the upper edges of the latter extend down on the outside of end walls 9 of the frame, and outside side panels designated 27b which are integrally joined to inside side panels 27a at the upper edges of the latter extend ,down on the outside of side walls 11 and 13 of the frame. The resultant enclosure can be placed on a bed, for example, for use as an infants crib. Or it may be placed on the floor for use as a play pen. With the basket'ma'de of polyethylene, for example, and with the heat-sealed seams 41 being watertight, the enclosure may also hold water and be used as a bathinette or-a wading pool. With portions of the ends and sides of the basket folded around the outside of the frame, the sides of the frame are prevented from folding outward.
In View of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.
As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted asillustrative and not in a limiting sense.
I claim:
