9 Claims.

I generally a plurality of trays so connected with the box and case and its movable cover as to be automatically laterally displaced with respect to the case upon the opening of the cover. The traysaregenerally referred to as cantilever trays due to the particular arrangement of links between the trays themselves and between the trjay's'and Case and cover. Carrying cases of the kind "and type herein disclosed are relatively I larger'eguiring considerablematerial to produce same and adapted torcarry and support a relatively heavy load. Several of the problems involved in the manufacture and production of the carrying cases includeinexpensive yet practical'fineansfor supporting the trays when the case isclosed as well as open, inexpensive yet practical and efficient operative mounting of the tray on the case and its cover and the general reorganization of the manufacture of a carrying case whereby lesser amount of material would utility.

. It is an object of this invention to provide a simple but sturdy means for supporting nested cantilever trays both when the carrying case is closed and when it is opened.

Another object of this invention is the mounting of the cantilever trays to acarrying case and its cover in which the least amount of material and] parts are employed consistent with emcient and sturdy construction. It is also an object of this invention to provide a cantilever tray support which supports the traysin both of its operating positions nested or superimposed when the cover is closed and extended when the cover is'open.

v,Other objects and advantages of the present invention should be readily apparent b reference to the following specification considered in conjunction with the accompanying drawings form-- ing a part thereof and it is to be understood that any. modifications may be made in the exact structural details there shown and described, within the scope of the ap ended claims, without departing from: or exceeding the spirit of the invention. a

Fig. 9 is a fragmentary longitudinal sectional View through the hinge of the case and cover taken on line 9.--9 in Fig. 8.

Fig. 10 is a perspective view of a hinge member forming a detail of the invention.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

As illustrated in the drawings the carrying case comprises box proper ID, a front cover H and a rear cover l2. The box proper includes the bottom panel l3 and front and rear walls I l and i5 integral with the bottom and bent substantially as illustrated in Figs. 2 and 4. Secured to the opposite ends of the front and back walls and the bottom, as by means of seams 1-6, are end walls I! and I8. The end walls I! and I8 have their upper edges inclined or peaked asat l9 and which peaked portions extend above the upper edges of the front and rear walls l4 and 15. The upper edges of the said front and rear walls l4 and I5 are offset respectively at 20 and 2! providing. inward

flanges

22 and 23 which lie behind the lower edges of the front and rear covers H and l2. r

The front and rear covers I l and I2 are respectively provided with a

vertical portion

24 and 25 from which inclined

top portion

26 and 21 extend toward one another with the rear cover top portion 21 terminating in a horizontal top portion -28 followed by a downwardly inclined top portion 29 which substantially meets there the inclined top portion 26 of front cover I! thereby providing the case with a peaked or triangular appearing cover. The free end of the top portion 26 is offset as at 30 to underlie the adjacent free end of the top portion29 whereby a substantially continuous cover is provided for the carrying case.

Each of the vertical portions of the covers is provided at its lower end with a bead 3| which acts as a hinge part for the cover and receives therein a hinge pin or rod 32 which extends substantially the full length of the case. The said lower edge of the case vertical portions are cut out at a plurality of points as illustrated at 33 in Figs. 1, 7 and 9. Disposed in said out out portions 33 are hinge members 34 each having at its lower end a U shaped bead 35 which cooperates with the bead 3| of the covers and receives centrally thereof the hinge pin or rod 32. Each hinge member 34 is adapted to have its body portion 34A contact One of the

case flanges

22 and 23 and is secured thereto by any desirable means, such for example spot welding 36 as illustrated in Fig. 9. The said hinge member is secured in such a position as to have the open end of the U bead or half bead 35 closed by the flange to which it is attached as clearly illustrated in Fig. 8. The hinge member 34 is clearly disclosed in Fig. 10 and offers a practical and economical hinge member for the conventional hinge member where a full bead is employed instead of the U bead 35. Each hinge member 34 is bent to overlie its box proper flange and project toward the center of the said box proper and is provided at its upper end with a ledge or flange31 parallel to the bottom panel of the carrying case.

The upper end I9 of the box ends I! and I8 is turned inwardly to provide a flange 38 which may in and of itself act as a reenforcement for said ends. In order to fully reenforce and strengthen the box ends use is made at each end of a liner 39 having a flange 40 which underlies the box end flange 38. The liner 39 extends downwardly to a point in the plane of the upper surface of the hinge members ledge or flanges 31 whereupon the liner, at its central point, is turned normal into the box to provide a flange 4!. The flange 4i, see Fig. 4, is a relatively short, transversely of the box, but does extend an appreciable distance on opposite sides of the vertical center of the box ends. In order to strengthen the flange 4|, which has its upper surface in the same horizontal plane with the upper surface of the hinge members ledges of flanges 31, it is provided with a pair of raised portions or. ribs 42. The end liners 39 are each provided with two or more depressions 43 causing the liners at these points to contact with the box end walls I1 and I8 and are then .connected to one another by means of spot well 44 extending therethrough.

Mounted on the end liner ledges 4|, respectively on each side of the vertical center of the end walls are

trays

45 and 46, which in turn have mounted thereon

superimposed trays

41 and 48. The outer longitudinal edges of

trays

45 and 46 are supported by the alined hinge members flanges 31 carried respectively by the front and rear walls I4 and [5. The trays 4548 may be individually provided with partitions extending transversely or longitudinally thereof as desired and as is well known and therefore not. illustrated in the drawings. From the foregoing it will be noted that the trays. aresupported along the.

outer edge particularly when the carrying case is closed, as illustrated in Fig. 2, as well as at their opposite ends.

The superimposed trays of each pair are pivotally connected to one another by a link 49 and through the. link and pivot 50, at the lower offset end thereof the trays are pivotally connectedv directly to. the end walls of the box proper. Each v of the lower trays has pivotally connected thereto a second link which through the pivot 52 in its offset lower end is likewise connected pivotally to the end walls of the box proper. Each of theupper trays has pivotally connected to it one arm 53 Ma compound link, the other arm 54 of which is respectively pivotally connected by til a pivot 55 through its offset and to the end wall of the front and rear covers. This linkage is such that movement, for example, of the rear cover I2 from the closed position illustrated in Fig. 2 to the open position illustrated in Fig. 5 moves the trays from a superimposed position, of Fig. 2, to an extended position, see Fig. 5, and when in this which are standard devices and whose operation is well understood. To prevent unauthorized access to the interior of the carrying case any type of locking means, such as disclosed at 58 may be provided for this purpose. In order to conveniently permit carrying or transportation of the case it has attached to its horizontal top portion 29 a. handle 59.

From the foregoing it will now be appreciated that there has been provided-a sturdy carrying case in which the elements for constructing the same have been reduced to a minimum utilizing various elements of the case for double duty, such for example. a hinge member as the element simultaneously supporting the trays, a reenforcing inner liner providing a reenforced supporting ledge for the tray, and the end members of the box proper for hinge mounting of the tray links, all tending toward simplification of construction of the carrying case without weakening the same.
