1. claim. (ci. 22o-s4) This invention relates to foldingA crates such as used for the crating of eggs for shipment.

It is desirable to provide folding crates so that when empty, they may be collapsed to occupy a fraction of their set-up volume. When collapsed, empty crates 'may be shipped as an incident to the shipment of reciprocal trade Lproducts on the return trip of a carrier to the source of the filled crate,

Foldable crates must, in addition to fulfilling their mission of collapsibility, provide a rigidity and strength of the order of that inhering in ordinary crates.

It is accordingly one of the objects of this invention to provide a collapsible crate, which, when set up, is substantially rigid and free from strain under influence of normal distorting forces. y

It is another object of the invention to provide a collapsible crate the at' walls of which are brought into closely adjacent planes upon collapsing thereof.

Other objects of the invention will become apparent to those skilled in the art upon consideration of the following specification in connection with the accompanying drawing, in which:

Fig. I is an isometric view of the framework of a crate the covering paper walls of which have been removed,

Fig. II is a fragmentary sectional plan taken from the plane II of Fig. I,

Fig. III is a fragmentary elevation from plane III of Fig. I,

Fig. IV is a fragmentary view from plane IV of Fig. I,

Fig. IVA is a view similar to Fig. IV showing a modified detail,

Fig. V is a view from plane V of Fig. I, and

Fig. VI shows a modified hinge detail.

The crate frame comprises a series of integral frame sections including a forward wall section III, end wall sections I2 and I4, rear wall section I6, central partition section I8, bottom flap section 20, and lid section 22,

Each of the sections is preferably fabricated of a series of round metal rods or tubes.

The front wall frame section I comprises a pair of

parallel beam members

24 and 26 rigidly joined adjacent their end portions and their midsection by

parallel uprights

28, 30, and 32.

The extending portions of the beams are bent rearwardly of the front wall to form eyelets 34 having their axis parallel to uprights 32 with the planes horizontal.

Lower beam 26 is provided with bottom-nap stops 36 which may be bent upwardlyto provide keepers 36.

Rear wall frame I6 is identical with thev front section except' forA omitting the bottom-apstops, and' that it faces its eyelets toward the front section.. f

The front 'and rear wall sections are linked together by end sections I2 and I4 comprising upper andilower beams 40 and 42y joinedby

uprights

44 and 46 adjacent the beam ends. The free beam ends are bent to form eyelets 48 having their axis horizontal and receiving the eyelets 34 in hinged interlinking relation therewith.

Bottom-fiap section comprises an M-shaped bail each leg of which is provided with an eyelet 50 adjacent its free end for the reception of lower beam 26' of the rear wall frame to hinge the bail and prevent vertical displacement-With respect thereto.

In order to prevent release of bail I8, as might occur as a result of a central compression from front to rearof the crate, the hook Fig. IVA, may be employed providing a pocket laterally of the line of compression for reception of the bridge portion of the bail whereby both tension and compression results in self locking action.

In order to restrict movement of eyelets 54, the

upright 30 may be offsetas at 64, Fig. VI, to hinge the eyelets in the oiset.

Cover section 22, of M-shape, is pivoted to beam 24 of the rear wall section by eyelets 66, which may encircle the beam between upright 32 and 28 and eyelets 34',

As shown in Fig. V the cover bail 68 overlies beam 24 and lies adjacent beam 40 to assist in fixing the prismatic shape of the frame when closed.

It will be observed from Fig. III that bottom section 20 underlies divider section I8 and is locked down thereby.

In order to collapse the frame, lid 68 is hinged rearwardlyand downwardly against rear Y.

wall section I6. Divider section I8 is rotated against section l0. Bottom section 20, being released, is folded upwardly adjacent section I6.

Sections I6, I0, I2, and I 4 are then free to collapse by hinging about the vaxes of eyelets 34.

The exterior faces of the frame sections have 5 secured thereto, as by staples 64, a suitable covering material such as cardboard or other nbreboard of suitable strength, each frame having a separate sheet secured toit. The staples may be placed so as to embrace the rod of the frame. l0

Suitable means to fasten the cover section down may comprise a cord secured through the cover material to the cover section frame and;y L

adapted to anchor to a suitable capstan on the` front section. Y'

VHaving described a preferred embodiment lof my invention and explained the principle there'-4 of, it will be understood that yreference shall be l' Y had to the claims for determination of Vwhatii l claim as my invention. 20

A collapsible crate comprising front and back .side frames formed of two uniform section elongated horizontal rods integrated with three vertical rods extending between the ends and mid- 25 points of said elongated rods, the elongatedv rods having four extension forming eyelets displaced 'laterally of the plane of the frames and having -the'axis of the eyelet openings disposed vertif rearward to form stops and keepers; a cover pivoted to the upper rod of the rear wall having eyelets secured therearound between the vertical Irods and the eyelets of the horizontal rods, said Y,cover being formed of rods in the shape of an M, "pivotally connected to the upper horizontal rod of the vrear Wall, and in closed position, the outer `legs of the cover lying in the plane of the upper horizontal rods of the end frame members; a rod formed, U-shaped partition frame pivoted to the intermediate vertical rod ofthe front side frame; locking hooks mounted on the rear side wall middle vertical rod for receiving the bridge of the partition frame; and an M shaped bottom member pivoted to the horizontal rod of the rear side wall frame.
