2 Claims. (Cl. 229-44) This invention relates to a box and more particularly to a rim for the body and cover of the box and a hinge for connecting the two together.

'One of the objects of this invention is to provide an arrangement of rim to better support the hinge between the parts.

Another object of the invention is to provide a construction which may be made. complete with the box and the body and cover sections formed complete and the two assembled as a final operation.

Another object of the invention is to provide a spring hinge box of such arrangement that the spring may be positioned in place after the rim is assembled with the body and cover sections.

Another object of the invention is to provide a rim which may be formed in a continuous strip and then bent into generally rectangular shape for fitting the edge of a rectangular box.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure l is a perspective view of the box in closed position;

Figure 2 is a perspective view of the .box in open position;

Figure 3 is a section of a fragmental portion of the box adjacent the sprin and hinge between the parts;

Figure 4 is a fragmental plan view of the corner portion of the rim showing the relationship of the parts;

Figure 5 is a sectional view on substantially line S5 of Figure 2 showing the manner of securing the rim to the side wall of the box;

Figure 6 is a perspective view of fragmental portions of two of the rims in the relation that each one bears to the other, showing the parts broken away and in section at the corners;

Figure 7 is a perspective view of one of the rims;

Figure 8 is a perspective view of the body of the box and both rims shown together and in position to be assembled with the body of the box;

Figure 9 is a plan view of one of the rims before being folded into generally rectangular shape;

Figure 10 is a plan view of a fragmentary portion of the rim stock prior to being formed into channel shape, the better to show the cut thereon for forming a corner of the rim shown in Figure 9; and

Figures 11 and 12 are sectional views of modified rim constructions.

In proceeding with this invention, I form a strip of channel stock by notching, cutting, and rolling of the parts so that this stock may be bent up into a rim of generally channel cross section to fit on the upper edge of a rectangular box, the rim having formed from one of the walls, preferably the outer wall, hinge eyes so that when two of the rims are assembled, a hinge pin may pass through the eyes to hingedly relate the two rims, which may thereafter be assembled on the box sections. The rims are specially formed at the corners for supporting the hinge, and the arrangement is such that springs may be positioned even after the rims are assembled on the box.

With reference to the drawings, 10 designates generally a rectangular body portion of the box provided with a bottom wall 11 from which there extend upwardly a front wall 12, a rear wall 1-3, and side walls 14 and 15. The cover section of the box comprises a top wall 16 with a front wall 17, rear wall 18, and side walls 19 and it), which depend from the cover. The upstanding and depending walls of the box are of a shape in the construction here shown to be in edge-to-edge abutting relation when the box is closed.

I position a metal rim designated generally 21 about the upper free edge of the body of the box and a metal rim designated generally 22 about the free edge of the cover of the box. Each of these rims is of identical formation and formed from a strip of channel stock, shown generally at 23 in Figure 9, which has the outer wall 24 (Fig. 8) of the channel continuous, while the bridge wall 25 and inner wall 26 are notched as at 27 and 28 (Fig. 9) so that the portion 29 between these notches will be of the length of the front wall either 32 or 17. Notches 3'9 and 31 form other portions 32 and 33 Which are of a length to extend along the side walls 14- and 15 or 19 and 20, while the end portions 34 and 35 extend along the rear walls 13 or 18. The folding occurs at these notches 27, 28, 30, and 31 by bending the outer Wall '24 which is continuous.

The edges of the notches 27 and 28 are on a miter of 45 degrees to the wall 24 so that when the rim portions 32 and 33 are bent at right angles to the portion 29, these mitered corners will abut and provide the seams 36 and 37, as shown in Figure 8. The notches and 31 are on a similar miter, but the end of the inner walls 32 and 33' are cut to provide tabs 38 as best seen in Figure 10. These tabs are bent at right angles so that when the sections 32 and 34 are folded at right angles, the inner wall 39 of these portions 32, 34 will abut against the tabs 38 as shown in Figure 4 and also as shown in Figure 6. By this arrangement any tendency for the free portions 34 and to swing inwardly relative to the portions 32, 33 is blocked by the said tabs 38.

The outer wall 25 along the end sections 34 and 35 is cut out so as to form spaced portions which are rolled to form hinge eyes 41 on the sections which are slightly off center so that when two of the rims are placed in opposing relation, the hinge eyes 41 on opposing sections will interleave so that a hinge pin 42 may be pressed through these eyes to hingedly relate the sections. In order that free movement may be provided in this hinge action, the cut-away portions of the outer wall may extend into the bridging wall 25 so that there Will be notches 43 formed therein. The lengths of the hinge portions 34 and 35 may be such that the two portions substantially abut, as shown in Figure 2, or these may be slightly spaced apart a distance sufficient so that springs may be inserted through the place between the ends for sliding along the rims into their final position. These springs are generally C-shaped, as shown at 45, with in-turned fingers 46 at either end to extend beneath the side walls of the channel of the rim so as to provide a spring relationship which will swing the covers to closed position when the angle bteween the covers is a little less than 45 degrees or will swing the cover to open position and form a stop to limit the opening movement after the cover has been swung away from the body a little greater than 45 degrees. While these springs may he slid on from the inner ends of the portions 34 and 35 which carry the hinges, it may be desirable to insert the hinges from the opposite ends, and in order to do so, I have notched the inner walls of the channel as at 48 and 40, as shown in Figures 7 and 8 so that the finger 46 of the springs 45 may be passed through these notches and then slid along the inner walls to the desired position, as shown.

The rims in pairs hinged together, as shown in Figure 8, with the springs in position may be assembled with the body and cover sections of a box by merely pushing these channels on to the sections, such for instance as shown in Figure 8 where the rim for the body is about to be positioned on to the body, by merely forcing the same downwardly on to the upstanding edges of the body of the box. Similarly the cover section will be assembled with the rim. In order to hold the rim on the walls with which it is assembled, the stock of the rim along the inner wall may be forced inwardly, as shown at 50 in Figure 5, by pressure of a tool, such as 51, which will be generally chisel shape with a bevel 52 so as to sever the portion of the wall nearest the bridging portion of the channel, as at 53, and bend it inwardly as at 54. The configuration of the inward projection will be generally a half cone so that any tendency for movement of the rim off the edge of the wall will be prevented. After the rim is assembled on the box, this shearing and holding may be accomplished in a press.

Preferably, the hinge eyes are located at a point spaced from the corners of the rim and also spaced from the end portions of the rim along the back wall as at 55 so that there will be an outer portion 56 of the rim at the ends to better assist in holding the rim closely adjacent thehinges for support where the greatest pressures are exerted due to the swinging of the sections on the hinge under influence of the springs which are applied.

In Fig. 11 there is shown a modified construction in which the wall 39 is provided with a tab 3? which is arranged to be at a position within the adjacent channel portion to engage against the end of the wall 33'.

In Fig. 12 there is shown a construction in which the wall 39 has a similar tab 39" but which is extended to be received in an opening 40 in the wall 33' to interlock therewith and secure these adjacent wall portions to each other.

I claim:

1. In a box a cardboard body section having a bottom wall with upstanding front, back, and side walls, a cardboard cover section having a top with depending front, back, and side walls, said back walls being in edge-toedge abutting relation, a pair of metal rims of channel shape, each receiving in its channel the front, back, and side walls of one box section, one of the walls of each channel rim along the back wall of each section being deflected to form hinge eyes and a hinge pintle extending through the eyes of two rims to hingedly relate the body and cover sections of the box, a C-shaped spring engaging one of the inner walls of each channel rim along the back wall of each section, an integral abutment on one of the adjacent inner wall corner portions of the side wall receiving portions of the rim engaging an adjacent corner wall portion of the hinge carrying portion of the rim to assist in preventing the hinge carrying channel portion from lifting through action of said spring.

2. In a box as in claim 1 wherein one of such c-shaped springs is adjacent each end of the back wall portion of said sections.
