VI/ANN a "CHAN/GAL Afform-ys for A l/cam United States Patent 3,223,466 FILHN'G CABINET Judson E. Roberts, Northridge, Calif, assignor to Holga Metal Production Company, Van Nuys, Califi, a corporation of California Filed Nov. 12, 1963, Ser. No. 322,777 11 Claims. (Cl. 312--220) This invention relates generally to filing cabinets and relates more particularly to a locking mechanism for multi-shelf filing cabinets.

While the invention has particular utility embodied in multi-shelf steel filing cabinets, and is shown and described embodied therein, it is to be understood that its utility is not confined thereto.

Certain problems and difficulties are encountered in providing a suitable locking mechanism for filing cabinets having a plurality of horizontal, vertically spaced shelves dividing the cabinet into a plurality of compart* ments, each of which is provided with a door. One of such problems involved in this type of filing cabinet is the provision of a locking mechanism which will lock all of the doors and is controlled from a single location or station.

it is therefor a general object of the invention to provide a locking mechanism for cabinets of the above de scribed character that will solve the problems involved and overcome the difficulties thereof.

It is another object of the invention to provide a lock ing mechanism of this character that will effectively lock all of the doors of the cabinet by actuation of a single door.

It is still another object of the invention to provide locking mechanism of this character wherein the lock rods are moved to the locking position by actuation of one of the doors.

It is a further object of the invention to provide locking mechanism of this character that is extremely simple in construction.

A still further object of the invention is to provide locking mechanism of this character that is simple in operation.

It is another object of the invention to provide locking mechanism of this character that is rugged and durable.

It is still another object of the invention to provide locking mechanism of this character wherein wear and breakage of locks is reduced to a minimum.

It is a further object of the invention to provide a locking mechanism of this character that is substantially tamperproof.

It is a still further object of the invention to provide mechanism of this character that is relatively inexpensive to manufacture.

The characteristics and advantages of the invention are further sufficiently referred to in connection with the following detailed description of the accompanying drawings, which represent one embodiment. After considering this example, skilled persons will understand that variations may be made without departing from the principles disclosed, and I contemplate the employment of any structures, arrangements or modes of operation that are properly within the scope of the appended claims.

Referring to the drawings, which are for illustrative purposes only:

FIG. 1 is a perspective view of a portion of a filing cabinet having locking mechanism embodying the present invention;

FIG. 2 is an enlarged sectional view taken on line 22 of FIG. 1;

"ice

FIG. 3 is an enlarged sectional view taken on line 33 of FIG. 1;

FIG. 4 is an enlarged fragmentary view, partially in section, showing a lock-dog on an installed lock-rod;

FIG. 5 is an enlarged sectional view taken on line 5-5 of FIG. 2;

FIG. 6 is an enlarged fragmentary View of a lock-rod with a lock-dog;

FIG. 7 is an enlarged perspective view of a lock-rod lift; and

FIG. 8 is an enlarged perspective view of a lock-hasp.

Referring more particularly to the drawings, there is shown a filing cabinet, indicated generally at 10, having side walls 11, a top wall 12, a back wall, not shown, a bottom wall, not shown, and a plurality of horizontal vertically spaced shelves, one of said shelves being indicated at 16 and the rest of the shelves being indicated at 17. While there are shelves 17 shown above the shelf 16, it is to be understood that there could be shelf 17 below the shelf 16 with the shelf 17 below the shelf 16 spaced vertically apart and also spaced vertically from the shelf 16.

The spaces between the shelves and defined by said shelves and adjacent portions of the cabinet walls, comprise storage compartments for the storage of files of various well known character. Each compartment is provided with a door having a horizontal pivotal axis adjacent the upper horizontal edge thereof. Each door has end flanges or walls 51 which are pivoted on pivots 20 adjacent the upper ends thereof, the pivots of each door being in axial alignment. The door for the compartment above the shelve 16 is indicated at 18 and the doors for the other compartments are indicated at 19. The doors have their upper ends spaced inwardly of the plane of the front edges of the walls of the cabinet and when said doors are in the closed position they are downwardly and forwardly inclined. Each door has an inturned flange 21 extending along the lower edge of the main body 22 of the door and normal to the plane thereof. From the rear edge of flange 21 there is a depending flange 24 with a back-turned edge portion 25 which is adapted to abut against the front face or edge 26 of the adjacent shelf.

The cabinet structure, feature and elements above described are of well known character and hence it is believed to be unnecessary to show and describe further details.

The present locking mechanism includes a vertical lockrod 30 at each side of the cabinet, each rod 30 being a flat strip of metal having a plurality of longitudinally spaced lock-dogs 31 punched from the body of the rod and extending at right angles to the plane of the lock-d, said lock-dogs all extending in the same direction, there being a lock-dog for each of the doors. Each lock-dog 31 has an uptunned flange 31a at the free end which prevents entry intothe filing compartments by pulling on the door thereof, deflecting the lock hasps hereinafter described or otherwise causing the lock-hasps to be forced inwardly and away from the lock-dogs.

The lock-rods are of the same construction and arrangement and the means for operably mounting said rods has the same construction and arrangement except that such means is arranged in opposing relationship with the lockdogs also arranged in opposing relationship at the sides of the front of the cabinet. Hence, a description of one such mounting or retaining means will be suflicient.

Referring to FIG. 5, the side wall of the cabinet has an inturned flange 33 along the front edge and at the inner edge of said flange 33 there is a backwardly turned flange 34 having its rear free edge engaging the front edges 26 0f the shelves adjacent their ends. The top and bottom walls of the cabinet also have a similar construction along the front thereof.

A stiffener member, indicated generally at 35, is pro vided and includes a part 37 spaced from the adjacent side wall and substantially parallel thereto, said part 37 having a forward portion in abutment with the backturned flange 34 :of the adjacent side wall and secured thereto by spot welding 'or other suitable means. There is an out-turned flange 38 along the front vertical edge of the part 37, said flange 38 being somewhat wider than the distance between the part 37 and the adjacent side wall and said flange 38 is in such engagement with the adjacent part of the side wall as to provide a wedging action to additionally secure the stiffener in position. Part 37 has a flange 40 extending obtusely rearwardly from its rear vertical edge and the flange 40 terminates at its 'outer end in a flange 41 abutting the inner side of the adjacent side wall and spot welded or other-wise suitably secured to said side wall.

The shelf is provided with a notch 43 extending rearwardly from the front edge thereof and of sufficient size to operably receive the lock-rod and retain same at each station. The portion or part 37 of the stiffener 35 is provided with 'a slot 44 therethrough at each station for reception of the respective lock-dog which extends through, the notch or slot 44 inwardly of the cabinet relative to said part 37. The slots 44 are of sufficient vertical length to permit the dogs and the rods 30 to move vertically between a locking position and a release position.

With a lock-rod extending vertically at the inner side and adjacent the forward or front edges of the side walls 11 of the cabinet, means is provided for actuating said rods. This means comprises a lock-rod lift 48 secured by spot welding or the like at the lower corners of one of the doors, such as the door 18, which is an intermediate door of the cabinet. The lock-rod lift members are of the same construction and include a front portion 49, the lower edge 50 of which rests on the rearwardly turned flange 21 of the door. To one of the end walls 51 of each door the portions 49 of the respective lock-rod lifts are welded or otherwise secured. Each of the lock-rod lifts has a cam 53 which extends from the inner side of the door at substantially right angles to the face 22 thereof and each cam has a cam surface 54 which extends from the free end thereof upwardly and outwardly when the dooris closed, there being a substantially horizontal edge 55 which extends outwardly from the upper end of the cam edge or surface 54 when the door is closed.

When the door 18 is opened the cam is, of course, inoperative. At this time both of the lock-rods are at their lowermost position, being urged to such position by gravity and limited in the downward movement by engagement of the lock-dog 31 with the lower end wall of the slots 44, the dogs then being spaced a limited, predetermined distance above the horizontal surface of the adjacent shelf When the door 18 is moved to the closed position the inner end portions of the cam surfaces 54 of the lock-rod lifts of door 18 engage the respective adjacent lock-dogs 31 and effect upward movement of the rods 30. When the door 18 is completely closed the respective lock-dogs thereof rest on the horizontal surfaces or edges 55 of said lock-rod lifts to thereby positively prevent downward movement of said lock-rods 30 when the door 18 is closed.

Door 18 is locked in the closed position by any suitable well known locking means, such as the key-operated lock 58, FIG. 1. It is to be understood, of course, that any other suitable locking means may be used whereby the free swinging edge of the door 18 is secured to a fixed or immovable part of the cabinet, such as the shelf 16. Other locking means may be of the combination type, for example. When the door 18 is unlocked and raised the lock-rod lifts disengage their respective lock-dogs 31 and the lock-rods will move downwardly under the influence of gravity to their lower limit of movement.

Each of the other doors of the cabinet have a lock-hasp, indicated generally at 60, at each corner of the free end. The lock-hasps are of the same shape and construction except that they are of opposite hand for the respective ends of a door and hence a description of one will be sufficient.

Referring to FIG. 8, the lock-hasp has a narrow intermediate part 61 which is in a vertical plane and is relatively narrow. At the outer end, relative to the door, there is a depending part 62 which is in the same vertical plane as the intermediate part 6-1. At the inner end of the intermediate part there is a generally triangularly shaped depending inner end part 63 having a cam edge or surface 64 at the forward end, said cam surface being inclined upwardly and toward. the front of the cabinet when the door is closed from the lower free end 65 of said inner end part. The forward part and the inner end part are spaced apart longitudinally relative to the lock-hasp.

The forward part 62 of each lock-hasp is secured to a respective end wall of a door by spot welding or any other suitable means. When the lock-hasps are secured to the doors the flanges 67 are oppositely arranged and are turned toward each other.

When the lock-rods 30 are in their released position, that is, when they are at their lowermost limit of movement, the lock-dogs thereof for the doors 19 are out of the notches 70 of the lock-hasps. However, when the door 18 is moved to its closed position to effect raising of the lock-rods to their uppermost position whereat the lock-dogs 31 for the door 18 are resting on the surfaces 55 of the lock-rod lifts 48, the lock-dogs for the doors 19, assuming said doors are closed, enter the notches 70 so that the door 19 cannot be opened.

The pressure required to raise the lock-rods is exerted by the actuation of the door 18 to the closed position, not by the turning of a key. This reduces wear and breakage of locks. Should a door 19 not be completely closed when the door 18 is closed, the lock-dogs 31 for said door 19 will engage the cam surfaces 64 of the lockhasps of said door 19 and will force the door to the closed position as said dogs are raised to their upper positions, as shown in FIG. 3.

The invention and its attendant advantages will be understood from the foregoing description and it will be apparent that various changes may be made in the form, construction and arrangement of the parts of the invention without departing from the spirit and scope thereof or sacrificing its material advantages, the arrangement hereinbefore described being merely by way of example, and I do not wish to be restricted to the specific forms shown or uses mentioned except as defined in the accompanying claims, wherein various portions have been separated for clarity of reading and not for emphasis.
