United States Patent() CABINET Jack Evans, Des Plaines, lll., assignor to Century Display Manufacturing Company, Inc., Chicago, Ill., a corporation of Illinois Application January 7, 1954, Serial No. 402,721

Claims. (Cl. 312-348) This invention relates, generally, to innovations and improvements in drawer cabinets. The invention pertains particularly to innovations and improvements which permit the manufacture of good drawer cabinets on a quantity production basis at relatively low cost.

The object of the invention, generally stated, is the provision of drawer cabinets having a rugged construction, which operate smoothly, have an attractive appearance and which can be produced from sheet metal and/ or plastic on a quantity production basis at minimum cost.

Certain other and more specific objects of the invention will, in part, be obvious and Will, in part, appear hereinafter.

For a more complete understanding of the nature and scope of the invention, reference may now be had to the following detailed description thereof taken in connection with the accompanying drawings, wherein:

Fig. 9 is a view partly in front elevation and partly in vertical section of the cabinet shown in Fig. 8; and

Fig. l0 is a perspective view showing an interior railproviding partition for the smaller upper drawers of the cabinet shown in Fig. 8 with bracing straps attached thereto.

In Fig, 1 a cabinet is indicated generally at 5 which consists of a cabinet case or shell 6 which houses four sliding drawers 7. The cabinet case or shell 6 may be fabricated from sheet metal on a quantity production basis and the drawers 7 molded from a suitable plastic. However, it will be understood that other materials may be used beside metal and plastic, and that the cabinet may be of an all-metal construction or it may have an allplastic construction.

The cabinet shell or case 6 consists of an outer case member 8 (Fig. 4) having a top portion 10 and two side walls 11 11, each of which has an inwardly turned ilange 12 extending along the bottom edge thereof. This member S may be stamped from a single piece of sheet metal. The front of the cabinet shell 6 is provided with a rectangular frame member 13 (Fig. 4) having top and bottom horizontal sides 14 14 and vertical sides 15-15. The member 13 also has inwardly beveled or inclined top and bottom ilanges 16-16 and side ilanges 17 17 which are suitably secured together at the corners as shown. A narrow horizontal flange 18 projects from the inner edge of each of the top and bottom inclined anges 16, and a narrow vertical tlange 20 projects from each of the side inclined anges 17. The member 13 may be stamped and died out of a single piece of sheet metal.

The rear of the cabinet shelf 6 is formed by an end member 23 (Fig. 4) comprising an end wall 24 having projecting therefrom top and bottom horizontal flanges 25 and 26 and vertical side flanges 27 and 28. This end member 23 may be stamped from a single piece of metal by use of the same die as is used to form the front member 13 after removing the parts which serve to form and bend the inclined llanges 16 and 17.

The front frame member 13 is inserted into the front of the shell member 8 as shown in Figs. l and 2 and is secured therein in a suitable manner such as by spotwelding as indicated at 30-30 in Fig. l. Likewise, the rear end member 23 is slipped into the rear end of the shegll1 miiiber 8 and similarly secured thereto as indicated at In addition to the members 13 and 23, the cabinet case or shell 6 includes a pair of side inserts 32-32, one of which is shown in Fig. 4. The inserts 32 constitute important elements of the combination and they contribute to and make possible the production of the cabinet 5 on a quantity production basis at a low unit cost. Each insert 32 comprises a vertical wall portion 33 from which project on one side upper and lower horizontal flanges 34 and 35 and from which project toward the opposite side Vertical tlauges 36 and 37. Four rails 38 for the drawers 7 are stamped or died out of the side wall 33 on one side thereof. Each of these rails 38 has a horizontal portion 40 (Fig. 5) and a vertical flange portion 41. Openings 42 are left in the side wall 33 where the material is stamped out to form the rails 38.

At the opposite ends of each of the rails 38 and slightly thereabove, drawer stops 43 (Figs. 5 and 6) are struck out from the side wall 33 leaving an opening 44 in each instance. It will be observed from Fig. 6 that the stops 43 adjacent one vertical edge of the insert32 are upwardly and inwardly inclined at an angle of about 45 while the stops 43 adjacent the opposite vertical edge are similarly upwardly and inwardly inclined.

When the cabinet shell or case 6 is assembled, the vertical anges 36 and 37 on each insert 32 serve to space the insert the proper distance from the adjacent side wall 11 as shown, for example, in Fig. 3. The top horizontal ilanges 34 of the inserts 32 fit up against the top anges 14 and 25 respectively of the front and rear case members 13 and 23 and the bottom horizontal llauges 35 of the inserts 32 rest on the bottom anges 14 and 26 respectively of the front and rear members 13 and 23, as shown in Figs. 2 and 3. The flanges 34 and 35 may be secured in place by spot-welding or some other suitable procedure. By having the stops 43 provided at opposite ends of the rails 38, each of the inserts 32 may serve either on the left-hand side or the right-hand side of the cabinet case or shelf 6. In other words, the insert 32 shown in Fig. 4 which is oriented for use in the right-hand side of the cabinet shell 6, could by rotating it around a vertical axis be used as the left-hand insert for the cabinet case or shell 6. Therefore, all of the inserts 32 may be identical and can be stamped out of sheet metal using only a single set of dies.

When the elements or members of the cabinet shell or case 6 are assembled, they fit accurately together and result in a rigid and strong cabinet shell or case. The front opening of the cabinet 6 presents a neat and attractive appearance with the front vertical edges of each of the inserts 32 fitting behind the inwardly turned vertical flanges 20-20 on the front frame member 13 as shown in Figs. l and 2, for example.

The cabinet 5 takes four drawers 7 which may be molded in one piece from a suitable plastic. Each of the drawers 7 has a handle 45 and lateral flanges 46 projecting along the tops of the opposite sides. The llanges 46 serve as runners which slide on the rails 38. The dimensions are such that the ang'es 46 iit over the tops of the rails 38 as shown in Fig. 3. The flanges or runners 46 do not extend all the way to the rear end of the drawers 7 but terminate short thereof and the end portion of each flange 46 is disconnected from the top edge of the drawer side wall and tilted up at about 45 as indicated at 47 (Fig. 2) for cooperation with the adjacent drawer stops 43.

Each of the drawers 7 is also provided on opposite sides with laterally projecting lugs 48 (Figs. 2 and 3), the upper surface of each of which is rounded or semicylindrical and with the uppermost portion thereof spaced below the bottom side of the adjacent runner flange 46 a distance slightly greater than the vertical height of the anges 41 on the rails 38 so as to fit and slide thereunder.

The bottom rear edge or corner of each of the drawers 7 is rounded as indicated at 50 (Fig. 2) so as to facilitate the removal of the drawers from the cabinet and re-insertion of the drawers therein. The manner in which the drawers 7 operate in the cabinet case or shell 6 is illustrated in Fig. 2. In that figure the bottom drawer 7 is shown in the fully inserted position so that the front wall of this drawer is approximately ush with the vertical lines of intersection between the inwardlyturned narrow vertical flanges of the front frame member 13 and the beveled or inclined ange portions 17. The drawer handles 45 are so dimensioned that the outer edges thereof lie even with or slightly behind the front corners of the cabinet case or shell 6. lt will also be seen that, when fully inserted, the lugs 48 on the drawers 7 just t underneath the rear ends of the adjacent rails 38 while the upper edge of each upwardly inclined hook portion 47 just fits against the adjacent stop 43.

While each of the drawers 7 can be smoothly pushed in and out of the cabinet, they cannot be accidentally removed by pulling too hard. Thus, again referring to Fig. 2, the second from the bottommost drawer is shown pulled out to the fullest extent possible without tilting the drawer upwardly. It will be seen that the upwardly turned hook portions 47 on the forward ends of each of the lateral runner flanges 46 engage with the adjacent stops 43 so as to prevent further outward movement of the drawer 7.

The lugs 48 serve to prevent the drawers 7 from tilting downwardly after they have been pulled out a distance where the center of gravity of the drawer and contents is sufficiently shifted outside of the cabinet so that the withdrawn portions of the drawer tend to tilt or pivot downwards. As the drawersl are pulled out to where they tend so to tilt, the rounded upper surfaces of each of the lugs 48 engage and ride smoothly underneath the bottom edge of the adjacent vertical flange 41 of the cooperating rail 38 so as to provide for the smooth and level operation of the drawers throughout their travel.

After one of the drawers 7 has been pulled out horizontally as far as possible, the drawer may be removed by pivoting it upward at a suitable angle as shown in Fig. 2 in connection with the uppermost drawer. It will be seen that when the drawers are tilted up at this angle the hook portions 47 can slide out between the bottom edges of the stops 43 and the tops of the rails. The inwardly inclined angle of the flange 18 at the top of the insert 13 is such as to permit the top drawer to be tilted up at a suicient angle for removal. It will be appreciated that the drawers may be re-inserted by inserting them at the same tilted angle and then lowering them to the horizontal position as they are inserted.

In Figs. 8-10 a cabinet is indicated generally at 55 which has two full-width lower drawers 56 and six smallsized upper drawers 57. The cabinet 55 has a case or shell 8, the construction of which may be identical with the construction of the case or shell 6 of the cabinet 5 except for obvious changes in respect to the number and spacing of the projecting rails on the side wall inserts 60. Each of these inserts 60 is of the same general construction as one of the inserts 32 but will have two lower rails 61-61 and three upper runners 62. The second and third runners from the top will be spaced so as to accommodate the smaller-sized drawers 57.

The cabinet 58 also has two additional insert members for the upper portion of the cabinet which are designated at 63 (Fig. l0). Each of these members has three rails 64 struck out from the side thereof and also has stops 65 struck out from the side wall material and which correspond to the upwardly and inwardly inclined stops 66 adjacent the opposite ends of the rails 62 on the inserts 60. The members 63 may be suitably secured together back-to-back and each is provided with a horizontal top flange 67 which may be secured into the top of the case or shell 58.

In order to brace the bottom front corners of the inserts 63, strap members 70 are provided having upwardly turned ends 71. The inner ends 71 are secured to the bottom front corners of the insert members 63 and the outer ends 71 of the straps 70 are secured to the side wall portion of the adjacent insert 60 as shown in Fig. 9.

The drawers 56 and 57 may have the same construction as the drawers 7 used in cabinet 5 and will operate in the same manner.

A number of obvious changes may be made in the cabinets described above. For example, one or more of the drawers may be provided with dividers. The smaller drawers of cabinet may be located at the bottom instead of at the top, or some of the small drawers can be at the top and some at the bottom with the fullsized drawers in between. The smaller drawers do not have to have the same width but can have different widths by suitably displacing the inserts to one side or the other.

Since certain further changes may be made in the embodiments of the invention disclosed and additional embodiments of the invention may be made without departing from the spirit and scope of the invention, all matter disclosed above or shown in the accompanying drawings is intended to be interpreted as illustrative and not in a limiting sense.
