4 Claims.
This invention relates to shipping containers in general and in particular to shipping containers which may be knocked down to save shipping space when being moved in an empty condition.
Large quantities of materials are transported in containers having capacities approximately one-sixth that of a standard railway car. Such containers are moved by truck, rail and ship and frequently must be returned to their destination in an empty condition since it is hard to locate return pay loads. This is particularly true of shipments of diplomatic and military material shipped over seas. Frequently also in domestic service containers must be returned Without pay load and without waiting for the movement of a special container car. It is an object, therefore, of the present invention to provide a shipping container which may be readily knocked down for return shipment and which will occupy a minimum of shipping space and will not require special shipping container cars.
A further object of the invention is the provision of a shipping container which may be readily knocked down or assembled and when in the assembled condition may be handled in the same manner as present permanently assembled containers A still further object of the invention is the provision of a knock-down container in which the door will be suspended from at least three of the sides during lifting of the container.
A yet further object of the invention is the provision of a knock-down container having the parts rigidly held in assembled condition by means of sliding bolts.
These and other objects of the invention will be apparent to persons skilled in the art from a study of the following description and accompanying drawings, in which:
Fig. 1 is a side elevational view with portions broken away to better disclose the construction;
Fig. 2 is a front elevational view of the container;
Fig. 3 is a rear elevational View also with parts vbroken away to better disclose the construction;
Fig. 4 is a top plan View of the container; Figs. 5, 6, '7, 8 and 9 are enlarged sectional views taken substantially on corresponding section lines of Fig. 2;
' Fig. l0 is a sectional View similar to Fig. 5 but showing the connection between a side and a rear wall;
Fig. 1l is an enlarged sectional view showing the connection between the side wall and oor,
and
Fig. 12 is a top plan view of the floor unit.
Referring now to the drawings in detail it will be seen, particularly from Fig. l, that the longitudinal side Walls are made of sheet metal plate 2, stiifened on its outer surface by means of two A-shaped braces 4 suitably spot welded or otherwise secured to the plate and additionally braced by a longitudinal tie 5. The upper ends of the A bracing members are provided with an eye in which is fastened a lifting loop 6 by means of which the container may be lifted during transport. As clearly shown, the braces are of iianged channel formation so as to give maximum rigidity with minimum weight. Along the bottom edges of each side wall is riveted or otherwise attached an offset plate 8 (Figs. 3 and 11), which oiset plate has the lower portion in direct contact with the side wall sheet 2 and the upper portion offset inwardly therefrom.
The back wall, particularly as shown in Fig. 3, is formed of metal plate I0 stiffened by anged channel stiffeners I2 extending vertically of the plate and spot welded or otherwise secured thereto. The top and side edges of the end wall plate lil are flanged inwardly as at I4 and I5 respectively. The top anges are adapted to support and be overlapped by the roof later to be described, while the side flanges I5 are adapted to overlap the side walls 2. Attached along the bottom edge of the end wall is an offset plate I6 similar in construction to the offset plates 8 attached to the side walls.
The front end wall, as best shown in Fig. 2, is formed by a top plate I8 and two vertically extending side plates 20 together defining a door opening. The plates I and 2d have their upper and side edges flanged inwardly as at 2| so as toy overlap the side walls and be overlapped by the roof in exactly the same manner as the anges It and I5 of the end Wall. Plates I8 and 2E! havel angles 22 attached thereto adjacent their inner edges, which angles stiften the plate and define the door opening. Hinges 24 are secured to plates 20 and angles 22 and carry a large door 2S and a small door 28. These doors are preferably built of fiat metal plate stiffened internally by angles 30.
" The door of the container, as best shown in Fig. 12, is formed of a top plate 32 resting upon and spot welded or otherwise secured to longitudinally and transversely extending flanged channel stiffeners 3%, all suitably connected together by welding or other securing means and attached at their outer ends to angular framing members. The framing members extending along the longitudinal sides and rear end are of deformed 2 bar shape having a bottom flange 3G, vertical web 38 and an outwardly and downwardly turned outer ange 40, which outwardly and downwardly turned flanges are adapted to overlap and interlock with. the distorted plates 8 and. lit`- of the side and end walls respectively. Thus it will be seen that during lifting the side and rear edges of the floor will be carried by and Supported along their entire length by the side and rear end Walls. of the assembled container. The front edge of' the floor frame is formed by Van angle 42 (Fig. 7.) to which is attached a flat plate 43- and stiifening angle 44, which latter will alsoserve as a protection plate during loading of the container;
The container roof, as best shown in Figs. 1 and 4, is formed of a metal. plate 46 havingthe side edges thereof turned downwardly as at 43 with the downturned edges overlapping the side and end walls of the container. The roof is internally stiffened by transversely and longitudinally extending hanged channel stiieners o suitably attached to each other and to the roof Dlate 46.
In order to secure the roof to the various side and end walls bolt keepers 52 are attached to the roof on the inner surface thereof and these keepers are preferably formed of short channel members to which are welded or otherwise secured tubular portions adapted to receive the free end. of bolts 54 slideably carried in similarly forrned bolt carriers 5t welded or otherwise secured to the side and end walls. The downturned ends 5G. of the bolts Ei/i will be held in their roof-locking position by angle retainers 62,
which retainers will also hold the bolts in their retracted position with loss of the bolts out of their carriers being prevented by small angle clips G3. Thus it will be seen that when the bolts: are in their locked position their accidental 1.
unlocking will be prevented by clips 62 and when in their unlocked position their locking or loss will be prevented by clips 62 and S3.
In each corner formed by the side walls and adjacent the upper and lower edges thereof keepers Iii of a form similar to keepers 52 are securely welded or otherwise secured to the side walls 2. Immediately above and below these keepers 1B. are spaced bolt slides 'l2 which are securely welded or otherwise secured to the rear and front wall plates lil and respectively. Slideably mounted in slides 'i2 and movable through keepers 1.0 are bolts 'i4 having a turned end 75. The right angle bend or handle portions 'LG .of the upper bolts are adapted to be held in position by the upper inclined edge of angle shaped retainers 'I8 when the bolts are in the locked position. When in the lowered or retracted position .the handles 'i6 are adapted to :fitA within a slot 19. of the angle clips to thereby retain .the bolt in its lower or retracted position, The `lower bolts 'i4 are held in their locked positionby means of the lower edgesof `angle clips 8.8, which clips are provided intermediate their ends with ,a slot 82 adapted to receive the handle portion 1G and retain the bolt in an intermediate position to assist in insertion and removal of the floor unit. When in thev fully retracted position .the handles I6 of the lower bolts areadapted to rest on .the upper. edge of retaining clips 8U with loss of the bolt being prevented .by angle members 83.
Thus it will .be seen that when the bolts 1.4 are. in .their fully locked position the side and .end walls are securely held together at a plurality of points. It will also be seen that the iloor is securely held in its position with the lips 40 in engagement with distorted plates 8 and I6 by means of the lower ends of the lower bolts 14. Upward motion of the lower bolts 14 is, as pointed out above, prevented; through' contact of handle T6 with the lower end of angle clips 86. When it is desired to remove the floor this can be done by lifting the lower bolts into slots 82 and lifting. and sliding the floor out of position.
The door 28' is securely locked in its closed position by means of upper and lower slide bolts 86 and 81' respectively, which bolts lock the door to the frame as. clearly shown in Figs. 2, '7 and 8. The door 26- is eiectively locked to the door 28 and to the door frame angles by means of slidesiiy suitably operated by a handle 90 which may be sealed against unauthorized tampering.
From the preceding it will be seen that with the container in the fully assembled condition none of the securing means can be reached by any personsv except by rst entering the container through door 26. When it is desired to dismantle the container bolts -54 will be moved to their retracted position between clips 62 and 63', after which the roof may belifted free. Following this the bolts 14 adjacent the front of the container will bev moved to their fully retracted position and the front wall with itsv attached doors removed, then the lower rear bolts 'i4 may be lifted in-to slots 82 and the floor unit removed. Following this the bolts 14 carried by the rear end walls will be moved to their full-y retracted position and the container will then be fully disassembled. In reassembling the container the reverse. operations may be followed, or the vside and rear walls may be laid fiat and the floor laid in position partially overlapping the lower edges thereof. Rotation of the sides and rear end wall to the vertical position will cause engagement. between the lips 4.0 and strips 8Iv and I6. In any event, whether the floor be placed in by thismanner or lowered into position, the `downturned lips will draw the .side andrear'end-wall into proper position for movement of the bolts i4 into their fully locked condition. It will also be obvious that seals of. either the resilient or spring metal type may be provided at all joints. It will likewise be obvious that4 various modifications ,andr rearrangementsy of parts may be. made without departing from the scope ,of the invention as defined by the following claims.
