1 Claim. I

This invention relates to a shipping crate of a type which may [be stored and delivered to the user in a knocked down condition whereby 'a minimum of space will be occupied until erected. A primary object of the invention is zto provide anexceedingly simple yconstruction of minimum weight Iand yet which will be quite rigid. A further important object of .the invention is to provide a base or pallet to receive the article to be encased and to supply the base mounted thereon, by means of which the encased article 'may be transported, and yat the same time form the base for supporting the case structure thereabove in lan interlocking manner.

A still further important object of the'invention is to provide -a structure ywhereby at least three of the side panels may loe integrally hinged `one to the other kpermitting use of berwboard or plywood and the like without requiring nailing .at the hinged corners. Further it is important that the superstructure above the pallet interlock with the pallet as well as with -a top `cover whereloy there is no tendency to spread apart. The structure is so provided that allparts thereof may be secured firmly on the v.pallet'and one against it bysirnply passing one or more straps or fbands around :the erected case.

These and many other objects and advantages of the invention will become apparent to those versed in the art in the following description o'f one particular form as illustrated in the accompanying drawings, in which Fig. l is ya view in front elevation of a strructure embodying the invention;

In the form of the invention 'herein Vs'howng'I provide 4a base'orpallet -IUVbuilt-up in any suitable manner fto have 'thefdimensions to receive and end 'portions on which are secured the rails |131 and |14. .'Ihen across the outer ends of these rails f|3 and |4 are secured side `trails f|5 --and flB. The .rail '|'5 lis :provided with tongues `|-1 and |8 whichextend entirely'to'the outer edges :of the underlying rails 4I3 and |54 .whereas the major ends L|9 and 2l) of the rail ll|'5 are. spaced inwardly respectively from those ifron-t .and'b-ack rails i3 and |4, Fig. 8. Likewise the 'top side Yrail I6 provided .with Atongues -2`| and 122 which .extend .out to ".the outer edges of those'rails |3Jand |4, whereas themajor end portions 23 and 24 ofthe. rail I6 are spacedinvva-rd-ly'fromthose edges.

Preferably, ywhile vnot necessarily so, a flolock 25 is laid on the topisi'de 'of :the rai-1 I3 between the rails l5 and vI6 tohave .its forward edges come withinithejpl-ane off the-ends |.9 and 23.

Referring to Fig. 7, arear panel '26 is provided to have side panels.21 and28shinged toits vertical edges. Theside lpa'ne1i21 hassecured thereto along its :front vvertical edge :and against its inside'facefapost 29. Likewise .a post '3U is'secured along the rear vertical .edge of this pan-el 21 against Iits face so that .when .the panel 21 is folded to extend at'right 'angles forwardly .from the rear .panel -26,'the back '.face :of ythe post 30 will fthen :zbe in lcontact againstii-,he forward face of the panel 26. In like manner, posts 3| and 32 :are secured against the inner iace4 of the panel 28. The lower ends of these posts 29, ,30, 3| land 32 terminate a distance above the lower edges of the panels '21"and28 equal to thefvertical thi-ckness of each of-the rails land |6. From the lower ends lof these posts, there extends downwardly in inwardly yspaced .relation from the panels 21 and 28 the tongues 33, 34, 35 and 3-5. The inward spacing vof these tongues from the panels equals the horizontalfthickness of each of the tong-ues I1, |8, 2|, and 22 as vmeasured-'from the Iouter side edges Aof the yrespective rails |5 land I6.

The horizontal lengthfoffeach rofthepanels `21 and P28 :is made tobe substantially -equal Ito theY lengths of these rails I5 Iand |6 'from end to end of 'their tongues. VThe horizontal 'length ofthe rear panel 26 is made'to-beequallto substantially the length-oftherail |4. `In-assernbling 'these side and rear'ipanels on the vpallet IU, `the -side panel 21 is assembled by having its lower edgey portion brought around along 'theouterside-of therail 15; the lower edge portion of thepanel 26hroughtacrossithefendsoithe rails |5-ran'd It across the rear rail I4; and the side panel 28 has its lower edge portion brought along the outer edge of the side rail I 6. 'I'he tongues 33 and 34 are forced downwardly along the inner sides of the tongues I1 and I8 and likewise the tongues 35 and 36 are forced downwardly along the insides of the tongues 2| and 22. When this connection is made, the panels 21, 26, and 28 will then be held against horizontal ydisplacement in any direction. 'I'he panels being on the outside of the rails I5 and I6, the various tongues cannot slip or slide inwardly. Also by reason of the opposing faces of the tongues 33 and 34 being in contact with the rail -ends I9 and 20, and likewise the inner faces of the tongues 35 and 36 being in contact with the ends 23 and 24 of the rail I 6, fore and aft movement is prevented. As indicated, the distance between rail ends I9 and 20 is ina-'de to be substantially the distance between the tongues 33 and 34, and likewise the distance between ends 23 and 24 of the rail I6 is made to equal substantially the distance .between tongues 35 and 36.

As indicated in Fig. 6, a top frame is built up to have side rails 31 and 38. The rail 31 terminates by ends 39 and 49, the distance between which equals the distance between upwardly extending tongues 4I and 42 that are provided on the posts 29 and 3D spaced inwardly from the face of the panel 21. The side rail 31 is provided with end extended tongues 43 and 44 shaped to t snugly between the post tongues 4I and 42 and the inner face of panel 21 when the top is in its closed position. In the same manner the other side rail 38 terminates by ends 45 and 4B spaced apart a distance equal to the spacing apart of the upper ends of the posts 3| and 32. Then there are the rail extending tongues 41 and 48 formed to fit between the post tongues 49 and 59 and the inside face of the panel 28. The top side rails 31 and 38 are spaced apart and maintained in proper alignment by the front and rear ties 5I and 52 which are secured to have those rails on their top sides thereof to have their front and rear edges respectively aligned with the outer ends of the respective side rail tongues 43, 41, for the ties 5I and 44, 48, for the tie 52. A cover panel 53 is secured to the top sides of the ties 5I and '52 in any suitable manner. The dimensions of this cover 53 are such that when the top structure is brought into position to have its respective tongues interengaged by the respective post tongues as above indicated, the outer edges of the cover 53 will be within the planes of the outer faces of the panels 25, 21 and 28. A ller block 54 may be used to ll in the space between the forward ends of the rails 31 and 38 to have its forward edge ilush with the rail ends 39 and 45, the block 54 being secured to the tie 5 I.

Now with the top structure above described positioned to have'its tongues interengage the -post tongues, the upper portions of the panels 21, 26 and 28, are held against any tendency to shift laterally one from the other since these panels are then interconnected with the top in the same manner as the panels are interconnected with the base I.

Thus it is to be seen that even though there be an article maintained on and secured to the base I0, such article being for example, a refrigerator of considerable weight, the side panels and the top may be brought around that article and interconnect one with the other. To complete the enclosure of the article, the front panel v55 is provided to t against the front faces of gaseosa the posts 29 and 3| and also at least across the ends of the cover tongues 43 and 41 and the base tongues i1 and 2I. In order to reinforce the panel 55, reinforcing strips 56 and 51, Fig. 9, are secured against the inner face of the panel 55 to have their lower ends bear against the forward edge of the member 25, and the upper ends against the ller block 54. Now in order to secure the members thus tted together and hold them against displacement during movement of the base Ill and the article carried thereon, preferably one or more straps 58 herein shown as two, Fig. 1, are carried entirely around the assembly under the base I0 between the runners II and I2 so as to be free of the floor or ground, upwardly vertically across the back panel 26 horizontally forwardly over the top assembly, and upwardly and downwardly respectively across the front side of the panel 55 to be interconnected at the joints 59 in any suitable manner such as is well known to those versed in the packing art where devices are well known to interengage and interlock ends of flexible metal straps. Of course, it is entirely feasible to nail or employ screws through the respective tongues to secure the panels, base and top one to the other, particularly where a one-time use only of the case is had.

While I have herein shown and described my invention in the one particular form it is obvious that structural, changes may be employed without departing from the spirit of the invention, and I therefore do not desire to be limited t0 that precise form beyond the limitations which may be imposed by the following claim.

I claim:
