Application September 21, 1943, Serial No. 503,224

4 Claims.

This invention relates to improvements in closed receptacles or cases, and more particularly to a means for pivotally mounting a cover on a body of the receptacle.

The invention is more specifically directed to the provision of a pivot structure for the cover of a closed receptacle that is patterned after the structure shown in my Patents #1,833,305 and #2,141,449. The first mentioned patent discloses a pivot structure for the body and cover of a receptacle that is held in operable relationship through the use of one or more springs. In the latter mentioned patent, this type of pivot structure has been applied to a three-element receptacle; namely, one having a base, cover, and intermediate element. In the present invention the intermediate element is combined with the cover and base of a receptacle to provide what may be termed a compound pivot structure.

One of the more important advantages and objects of the structure of the present invention lies in the multiple use of a pivot structure of the type shown in Patent #1,833,305 to obtain a full 180 opening of the cover with respect to the body of the receptacle.

Another advantage and object of the invention lies in the provision of a, pivot or hinge structure that utilizes a part of one of the walls of either the cover or body of the receptacle as an intermediate pivot element.

Another object of the invention is to provide, in a structure of this kind, means for preventing over pivoting in at least one direction.

A further object of the invention lies in the provision of a relationship of cover and intermediate element depth to base depth by which to enable movement of the cover to an inverted position where it may rest upon the same surface as the receptacle base, and it is also contemplated that in the application of the present invention to diiferent uses the relationship of cover element and body of the receptacle may be varied.

Other objects and advantages of the invention will be more fully understood from av consideration of the following specification, taken in conjunction with the accompanying drawing; and in which Fig. 1 is a perspective view of a receptacle and closure in which is embodied one form of the invention, the closure being shown in partly open position;

Fig. 2 is an enlarged fragmentary vertical sectional view of the pivotal connections of the elements of the receptacle, being shown with the cover in closed position, and is taken substantially as indicated on the line 2-2 of Fig. 6;

Fig. 3 is an enlarged fragmentary vertical sectional view of the elements of the receptacle with the cover in partly open position, similar to' the cover position of Fig. 1;

Fig. 4 is a fragmentary vertical sectional View of the elements of the receptacle with the cover in fully open position;

Fig.-5 illustrates the position of the operative parts of the receptacle in a position intermediate the position shown in Figs. 3 and 4;

Fig. 6 is a fragmentary horizontal sectional view taken through one of the pivot structures, substantially as indicated by the line 6-6 of Fig. 2; i

Fig. '7 is a fragmentary vertical sectional view taken substantially on the line 11 of Fig. 6; and

Fig. 8' is a fragmentary exploded view of the elements in their relative positions as illustrated in Fig. 2. I

Reference is had more particularly to the drawing wherein the numeral I0 is employed to generally designate a closed receptacle in which one form of the present invention is embodied. This receptacle comprise a' base portion ll, cover l2, and intermediate element 13. The base H includes any conventional side, front, and base walls, l4; l6, and I1, respectively; A- rear wall I8 is not-co'nventionalinthat-it is cut away to provide a recessed area l9 along its upper edge and this cut away portion constitutes the intermediate element l3. 1

On the upper edge'of the wall I8, one 'or more rolledportions orbeads 2| are provided, these beads being preferably set toward the rear edge of the wall and in some instances extending in part beyond the vertical edge of this wall, substantially as illustrated in the drawing. Of course the bead 2| may be continuous across the entire wall 18, except as interrupted at one or more places-in its length by'a recessor slot22 which extends downwardly of the wall l8 from the bead.- The base wall 23 of this recess is preferably formed in a predetermined curve or provided with suitable projections on its surface and terminates in a spring seat 24. As is customary in this type of pivot structure, the wall 23 is so curved, or projections on its surface are so disposed as to constitute a stop to limit movement of the intermediate element 13 to a desired degree by contact thereof with a strap spring which forms a part of the pivot structure.

The cover I2 includes a top wall 26, side wall 21, front wall 28, and rear wall 29. The wall 29 terminates along its lower edge in a recess or seat 3| which receives, and is complementary to, a bead formed on the intermediate element l3 and, for convenience, preferably corresponds in proportions to the bead 2| of the body element l I. This recess, if continuous across the edge of the wall 29, may be interrupted by one or more slots 32, each lot having a curved base wall 33 which terminates in a spring seat 34.

Of course the length of the recess 3| in the present disclosure will be not greater than the length of the recess l9 or the intermediate element l3. Furthermore, although that portion of the wall 29 providing recess 3|, extends somewhat beyond the edges of the remaining walls of the cover, this is not to be construed as a fixed position for this recess, since it may be within the limits of the cover walls or extend a greater distance beyond that shown in the drawing.

The intermediate element l3, in the present showing of the invention, is proportioned to fit into the area iii of the wall 18 and includes a seat 36 on its lower edge that is complementary to and adapted to at least in part receive the head 21. As indicated by the drawing, .this element may be of the same thickness as the rear walls of the base and cover of the receptacle-and the seat 38 will of course correspond in length to the length of the bead 2|. The upper edge of this element is formed with a bead 31 that, as mentioned, is complementary to the seat 31 of the rear wall of the cover. ment are interrupted by one or more slots 38. The base Wall of this slot is formed with opposed spring seats 39 and H from which extend curved surfaces 42 and 43. The curved surface 42 forms a continuation of the curved surface 33 when the cover is in the position shown in Fig. 4 of the drawing, and the surface 3 forms a continuation of the surface 23 of the base when the cover is in the position shown in either Fig. 3 or 4. The intermediate element l3, as shown, is of sufficient width to facilitate vertical alignment of slots 22, 32, and 38, and if, as shown in Fig. 1, the receptacle is so proportioned as to require only two holding springs, there will be only two of each of these slots in the elements of the receptacle. When the elements are assembled, C springs 44 may be snapped into engagement with the spring seats and will serve to secure the elements in a pivotal relationship such that the cover l2 may be moved with respect to the base in a manner illustrated in the drawing.

Should it be found desirable to incorporate the present pivotal structure in a closed receptacle.

01' considerable proportions, or assure accuracy of the fitting of the cover on the body of the receptacle when moved to a closed position, the intermediate element l3 may be formed with ledges or shoulders 48 at its ends which are complementary' to projections 41 in the vertical edges of the area 19. These complementary shoulders and projections may preferably be formed with inclined meeting surfaces which cooperate, during a closing operation, to accurately center the intermediate element within the area it and thus assure the cover edges aligning with the edges of the walls of the base. Additionally, if that portion of the rear wall 29 of the cover, in which the seat 3| is formed, extends beneath the normal cover edge (substantially as shown), this part will also be caused to accurately enter the upper portion of the area 19 by reason of the shoulder, projection combination Ii, 41 of the intermediate element.

Both seat 36 and head 31 of the ele- In a structure of this kind, and possibly due to a difference in temper of one set of springs with respect to another, or in the manipulation of the cover, it is possible that there may be a tendency of the connection, between the base of the receptacle and the intermediate element, or between the intermediate element and the cover, to permit over pivoting, especially during a closing operation. By over pivoting is meant a. tendency of bead and recessed parts to become separated by movement in excess of the normal relative movement prescribed by the springs. For example, in moving the cover from the position of Fig. 4 to that of Fig. 2, the parts pass through the position suggested in Fig. 5, and should continued movement of the cover in a closing direction move the intermediate element l3 into a position of align ment with the wall l8, the intermediate element could not further pivot or swing into th base of the receptacle, by reason of its contact of the shoulders 46 with the projections 41. To prevent over pivoting as between the intermediate element I 3 and cover l2, suitable lugs 48 may be provided. These lugs may be integral with the intermediate element or attached thereto, and serve to abut the inner face 49 of the rear wall of the cover when the cover is, for example, in the position shown in Figs. 2 and 3. It will, of course, be understood that the number and size of the lugs 49 will necessarily vary as to the size of receptacle, number of springs, and use to which the receptacle may be put.

Although applicant has shown and described only one form of a compound pivot structure by which to move the cover of a receptacle into a or more open position, it will be understood that with a further recessing of the rear wall of the receptacle, an additional intermediate element might be provided similar to the element l3 and by means of which, with consideration being given to the depth of cover, receptacle, and intermediate element, the cover might be movable into a back-to-back position with respect to the base, and such variations of the structure, together with other adaptations necessary in applying the invention to a variety of materials, are contemplated as being within the scope of the invention insofar as they are set out in the annexed claims.

Having thus set forth my invention what I claim as new and for which I desire protection by Letters Patent is:
