Interlocking Crating System

1. Field of the Invention

The instant invention relates generally to box-like structures and more specifically it relates to an interlocking crating system.

2. Description of the Prior Art

Numerous box-like structures have been provided in prior art. For example U.S. Pat. Nos. 695,618 to Mack; 1,736,539 to Lachman; 2,759,622 to Simmons et al.; 3,266,656 to Kridle and 4,854,461 to Daniel et al. all are illustrative of such prior art. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.

As an article of manufacture a skeleton for boxes consisting of a continuous piece of metallic angle-bar bent to form upper cross members, corner-posts, and floor members. The ends of the angle-bar being rigidly united to form a one-piece frame, together with metallic braces extending between and riveted to opposed parallel members of the continuous one-piece frame.

A joint structure comprising two body elements, a uniting body having a face conforming in shape to the faces of the body elements and having an elevated member intermediate of the face of the uniting body conforming in shaped to the edges of the body elements. The faces of the body elements being welded to the face of the uniting body with the edges of the body elements adjacent to the elevated member. The elevated member has a portion overlapping the adjacent portions of the body elements. Certain of the uniting bodies having extended welding ridges extending in the same general direction as that of the elevated member and penetrating the substance of other of the united bodies.

A boxlike animal cage of knock-down construction comprising a pair of side walls, front and rear walls and top and bottom walls. A structure is for preventing relative rattling movement between the walls comprising flanges secured to the proximate ends of the side walls and front and rear walls for slideably interconnecting the side walls in substantially right angular relation to the front and rear walls. Channel-shaped guide members are secured to the upper and lower edges of the side walls and are adapted to slideably receive the side edges of the top and bottom walls. Vertical ribs are secured to the top and bottom walls adjacent the side edges thereof. Flanges extending from the channel-shaped guide members are engageable with the ribs on the top and bottom walls for clampingly holding the top and bottom walls in position. Spring locking members are secured to the upper and lower edges of the rear wall. The spring locking members are generally channel-shaped in cross-section and includes an inwardly bent portion clampingly engageable with the top and bottom walls adjacent their rearmost edges. A component is for frictionally and detachably securing the front edges of the top and bottom wall to the front wall.

A demountable shipping case comprising a base generally in the form of a pan having a generally flat bottom and a lip extending upward from the flat bottom generally around the periphery thereof. A cover in the form of a pan, generally similar to the base, has a flat top and a lip extending downward form the flat top generally around the periphery thereof. The cover is sufficiently different in size from the base, to facilitate an easy telescopic fit between the two. Side panels are unconnected to the base normally when the case is in an assembled configuration and when the case is demounted. Corner posts are for insertion within the corners of the base and the cover. Each has two channels, one of the channels oriented to receive the edge of a side panel and the other of the channels is oriented to receive the corresponding end of a side panel adjacent to the end of the first-mentioned panel when the case is assembled. The length of each panel is sufficiently shorter than the distance between the bottoms of the two corner-post channels receiving, respectively, the opposite ends of the panel. When the corner posts are retained within the corners of the base, the panel slips easily into the two channels. The depth of the sides of both the channels are sufficient to prevent any gap, which would expose to access from the exterior the contents of the case, at the corners between the side panels and the corner posts when the case is assembled with the cover in position. The cover and the base retains the case in an assembled configuration without the need for fastenings between contiguous parts.

A storage box, particularly adapted for seed storage and handling, having folded corners and sides tapered from bottom to top. The box is provided with a base member having slots engageable by the tines of a fork lift and horizontal top stacking flange which extends outwardly to the same dimensions as the base member for vertical stacking of the boxes. The box is preferably constructed of steel plate and the folded corners assure the strength and integrity of the box.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide an interlocking crating system that will overcome the shortcomings of the prior art devices.

Another object is to provide an interlocking crating system that contains a skeletal framework assembly to hold plywood panels together in a locked position, to form a box-like configuration to transport various articles therein.

An additional object is to provide an interlocking crating system in which the skeletal framework consists of a plurality of panel holders, corner lock members and rail members that fit and interlock together to maintain the box-like configuration with plywood, plastic, metal or any suitable material panels.

A further object is to provide an interlocking crating system that is simple, reusable, recyclable, and easy to use.

A still further object is to provide an interlocking crating system that is economical in cost to manufacture.

Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
