Nov. 1, 1949 w. c. MITCHELL FILING CABINET UTILITY SHELF Filed Nov. 12, 1947 JNVENTOR. W41 rm 6. M/TCHfLL FIG--2;
Patented Nov. 1, 1949 v UNITED STATES PATENT OFFICE 2,486,966 FILING CABINET UTILITY SHELF Walter C. Mitchell, Whittier, Calif. Application November 12, 19497, Serial No. 785,453 3 Claims. (01. 311-17) This invention relates to cabinets for the files storage of letters or other sheet material and has particular reference to the construction of the drawers of such cabinets by means of which a portion of a drawer may be moved into a position wherein it may be made to serve as a supporting shelf, for the reception of papers or the like removed from the file, or as a writing desk.
An object of the invention is to provide, in a filing cabinet structure, a work-supporting shelf which when in folded non-use position becomes an inconspicuous portion of the drawer of such cabinet.
Another object of the invention is to provide a work-supporting shelf of the character described which, in its position of use, is entireh exterior of the cabinet drawer and preserves the utilitarian features of the drawer in preventing toppling over of the papers which may be arranged edgewise vertically in the drawer filing space.
A further object of the invention is to provide a shelf of the type referred to which may be readily incorporated in existing designs of filing cabinets without materially altering the cabinet structures or incurring excessive 1n the construction of the cabinets.
Still another object of the invention is to provide, in a filing cabinet structure wherein an adjustable work shelf is included as part of and cooperative with a drawer front of the cabinet, improved hinge and lock means connecting the work shelf and drawer front.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawings and description may be adopted within the scope of the invention as set forth in the claims.
Referring to the drawing:
Figure l is a perspective view of a filling cabinet showing the work-supporting shelf of my invention in extended position.
Figure 2 is a vertical sectional view taken in the plane indicated by the line 2-2 of Figure 1.
Figure 3 is a view similar to Figure 2 showing the shelf in retracted position.
Figure 4 is an enlarged perspective view of the lock rotor.
In carrying out my invention, I utilize a base structure comprising a conventional filing cabinet or the like having a housing 4 containing one or more drawer recesses 6 for containing the slidable drawers 1. less of conventional shape having the usual bottom 8, side walls- 9, and front panel ll defining the receptacle l2 in which the letters, folders or additional cost These drawers are more or other papers may be arranged in edgewise vertical and horizontally parallel relationship.
Arranged exteriorly of and overlying the front panel I l, I provide a false front member l3 equal, at least, in area to the former panel. This front member forms the shelf of my invention and is arranged, by. pivotal connection with the panel ll, to'be moved between a position of non-use, shown in Figure 3, wherein it lies contiguous with the panel II and functions cooperatively therewith as the drawer front, and a position of use, shown in Figures 1 and 2 wherein it extends horizontally from the panel H, preferably along the lower edge of the latter, to function as a shelf for the reception of papers removed from the file or as a depository for papers about to be inserted into the file. The shelf may also conveniently function as a desk for supporting the file papers as notations or other markings are being written or stamped thereon.
The manner of hinging the front shelf member l3 to the front panel I l and for locking the former to the latter so as to form an inseparable front structure for the file drawer forms an important part of my invention. As here shown, I provide a pair of brackets l4, secured by screws 16 or by other suitable means to the shelf member l3 at opposite ends of the lower edge thereof, which are each provided with wings I! extending therefrom which have therein arcuate slots l8 whose center of curvature substantially coincides with the lower edge of the member l3 facing the front panel ll of the drawer. The wings I! are passed through apertures l9 formed in the lower side portions of the panel I l and headed pins 2|, secured to the inner surfaces of the side walls 9, are slidably engaged in the wing slots l8. Thus the member 13 is mounted to pivot about its innerlower edge relative to the panel H from a vertical position contiguous with the latter to an extended position horizontally and angularly related to the panel. It will be noted that in its extended position, the bottom edge of the shelf member lies against the front of the panel I I while the pins 21 occupy the distal ends of the slots 18 relative to the shelf member thus providing elevated anchor points above the contact point of the shelf and panel H and affording adequate stabilizing braces for the shelf member to withstand normal downward pressures which may be imposed on the shelf member.
Since the shelf member i3 forms the outermost front portion of the drawer structure and consequently carries the pull grip 22, it is essential that the shelf member, when in its edge- Wise vertical position of non-use, be securely locked to the panel H in order to prevent relative separation of the parts during the action of opening the file drawer. As here shown, I provide eachof the wing slots I8, at the end thereof nearest the shelf member. [3, with a radially-ex tending notch 23 adapted to be entered by the pin 2| upon slight upward movement of the shelf member when the latter is in its aforesaid edgewise vertical position, This looks the, lower portion of" the shelf member against horizontal outward movement away from the panel I I. I also provide the upper edge portion of the panel H with one or more downwardly-lopening 24 into which the upper edge portion of the shelf member may pass as the latter is vertically raised so as to thus lock the upper portion of the shelf member to the drawer panel II. The means for raising and holding the shelf member may take one of several suitable forms but I have chosen to show, as illustrated in Figure 4, a look ele ment comp s g a shaft 26, extending hr u h and journaled in the lower portion of the shelf member, having an exposed. knob 2'! for rotating the shaft and further being provided at its inner end with an integral eccentric or similar cam 28' having a throw equivalent to the desired amount of vertical movement of the shelf member and adapted to enter an bottom portion of the panel II and to bear, as shown in- Figure 3., against the lower side of the latter aperture or against the upper surface of the drawer bottom 8 depending upon design. It will be seen that when the shelf member is moved to edgewise vertical position lying contiguously with the panel I l and the knob 2'! is manipulated to rotate the shaft 26, the eccentric or cam 28 will effect the aforesaid raising of the shelf member to engage the upper edge portion of the latter in the hooks 24 and to cause the pins 2| to enter the notches the shelf member in its position of non-use and permitting the normal strains of openingthe drawer to be imposed thereon without danger of causing dislodgement of the shelf member. Placement of the locking cam 29 closelyadjacent the hinged edge of the shelf member minimizes surface obstruction in the working area of the latter.
In reiteration, it will be seen that I have provided a shelf member for use with filing cabinets or the like which forms an inconspicuolls part of th drawer structure, which may be easily and rapidly moved between operative and inoperative positions, which affords, with each drawer, f
an unobstructed work surface of the greate t permissible area, which may be securely locked to form, in effect, an integral part of the drawer structure and which does not add materially to the complexity of the drawer structure nor to the constructional costs of the file as a whole. In addition, it will be seen that by providing asolld and stationary front wall for the drawer, eme bodied in the panel H, the drawer contents are kept from toppling over forwardly of the drawer which might occur if the shelf member l3. alone formed the drawer front.
I claim:
1. In a filing cabinet provided with a sliding drawer having a stationary front panel therein for holding contents of the drawer from mover ment beyond. the forward end th reof, a shelf member substantially equal in area. with said front panel means hingedly connecting said mem: her with the drawer for movement between posis ti'ons contiguous with and angular-1y related to said front panel, said hing means pro idin a a e ex nd g tw en the front ane and. shelf member at points be ond the hinge axis when said shelf mem er is in its ansularly r lated aperture 29 located in the 23 thereby securely locking position, and means operative upon parallel planar movement of said shelf member relative to said front panel when in said contiguously related position for locking the shelf member to said front panel.
