OTTO LEWIN ATTORNEY United States Patent 3,284,14? LGQKHNG ARRANGEMENT FOR MULTIPLE DRAWER CABINETS AND THE LIKE @tto Lewiu, York, Pa, assignor to Cole Steel Etguipment (10., Inc, New York, NC! a corporation of New York Filed Apr. 23, 1965, Ser. No. 45%,3tl0 16 Claims. (Cl. 312-218) This invention relates to cabinets and more particularly to a locking arrangement for multiple drawer cabinets.

Multiple drawer cabinets, such as those commonly used for filing or as pedestals for desks, are often provided with a mechanism to lock the drawers thereof against being opened by unauthorized personnel. Such locking mechanisms quite often take the form of a bar or slide disposed for rectilinear sliding movement, along either the sides, back, or top of the cabinet, and in response to the actuation of a key controlled lock, slidably disposed in the cabinet, and interconnected with the bar or slide by suitable connecting means.

In conventional cabinet constructions the great majority of the cabinet space is devoted to the drawers and the suspension mechanism therefor and the area remaining, in which the locking mechanism must be disposed, is considerably small and almost invariably closely disposed to either the sides, top, or the rear walls of the cabinet. Such confined spacing has a considerable effect on the time required to assemble the locking mechanism into the cabinet and thus reflects heavily in the cost thereof.

it has become common practice, in assembling a locking mechanism into cabinets, to secure some or all of the pieces thereof into the cabinet by the use of intermediate connecting devices, such as, screws, bolts, rivets, etc. and to also interconnect the various elements of the locking mechanism in the same manner. However, due to the confined area wherein the locking mechanism is to be installed, the alignment of the elements to facilitate the installation thereof in the cabinet and the interconnection of one with the other by the use of such intermediate connecting devices is a tedious, cumbersome, time-consuming and expensive task.

It is therefore an object of this invention to provide an improved mechanism for securing one or more of a plurality of movable members against movement.

It is a further object to provide an improved locking arrangement for a cabinet and the like and especially a multiple drawer cabinet.

A still further object is to provide a locking arrangement for a multiple drawer cabinet wherein the elements of the locking mechanism are interconnected without the use of intermediate connecting devices such as screws, bolts, rivets, etc. to facilitate the ready interconnection thereof and installation within the cabinet.

Another object is to provide a locking arrangement for a multiple drawer cabinet wherein safety features are provided to prevent release of the locking mechanism by unauthorized personnel.

This invention involves multiple drawer cabinets of the type used for filing, and of the type used as pedestals for desks, wherein a locking bar is mounted closely adjacent one of the inner walls of the cabinet for longitudinal rectilinear movement, between a position coacting with stops provided on the drawers to prevent movement of the drawers from within the confines of the cabinet and a position removed from the path of movement of the drawer stops to permit movement of the drawers from within the confines of the cabinet, such longitudinal rectilinear movement of the locking bar in turn being effected by linear movement of a rotary barrel type lock between an unlocked and a locked position, and through the intermediary of a member interconnecting the lock and locking bar and adapted to transmit the linear motion of the lock to the locking bar; and contemplates mounting the lock and the connecting member and interconnecting the lock, locking bar and connecting member without the use of intermediate fastening devices, members or elements (such as screws, bolts, rivets, and the like) to thus facilitate rapid, efficient, and economic interconnection thereof.

In carrying out the invention, according to a preferred embodiment thereof, an inner wall of a multiple drawer cabinet has formed from the material thereof structure for receiving a lock, for guiding longitudinal rectilinear movement of the lock, for determining the extent of movement of the lock in one direction, and for coaction with the bolt of the lock to latch same in a locked position; as well as a fulcrum upon which a connector-actuator is pivotally mounted. The connector-actuator is formed with a portion facilitating the pivotal mounting thereof on the fulcrum, a hook disposed for coaction with a pin carried by the lock to interconnect the two, and an arm extending into an open side-d channel formed in the material of a locking bar disposed in the cabinet for movement between raised and lowered positions. A spring acts on the connectoractuator to urge same in an appropriate direction to raise the locking bar and move the lock to an unlocked position.

Other objects, features, and advantages of theinvention in its details of construction and arrangement of parts, will be seen from the above, from the following description of the preferred embodiment when consid ered in conjunction with the drawings, and from the appended claims.

In the drawings:

FIG. 1 is a fragmentary perspective view of a multiple drawer cabinet cut away in part to better show the details of a locking mechanism therefor embodying the present invention;

FIG. 2 is a fragmentary perspective view cut away in part of the construction of the inner forward righthand wall of the cabinet of FIG. 1;

FIG. 3 is a fragmentary sectional view taken on line 3-3 of FIG. 1 showing the locking mechanism thereof in its actuated and locked condition;

FIG. 4 is a view similar to that of FIG. 3 but showing the locking mechanism thereof in its unactuated and unlocked condition; and

FIG. 5 is a partial fragmentary sectional view taken on line 5-5 of FIG. 1.

For convenience, the invention will be described as applied to a multiple drawer cabinet of the type commonly used for the filing of papers, documents, and the like, and usually referred to as a file cabinet; it being understood nevertheless that without departing from the scope of this invention that subject locking mechanism may be applied to a drawer cabinet of the type used as a pedestal for a desk or table or to any other cabinet wherein there are one or more drawers movable from a position within the confines of the cabinet to a position exposed from the confines of the cabinet, and which are provided with locking mechanisms to secure such drawers against movement by unauthorized personnel or for that matter to any construction wherein there are one or more members which are to be secured against movement.

With reference to FIG. 1 there is shown generally at a file cabinet of the kind commonly used for the purpose of storing papers, reports, and the like, consisting of a casing 12 formed with a top 14, a rear wall 16, a right-side wall 18, a left-side wall 20, and front frame 22, and within which are slidably disposed drawers 30, each including a front panel 32 supporting a drawer handle 34 and supported by a drawer body 36.

Suitable suspension mechanism (not shown) is disposed within casing 12 to support each drawer 30 for movement between a position wherein front panels 32 of drawers 30 are in the same plane as front frame 22 of casing 12 to thus prevent access to whatever is stored in drawer body 36, and a position wherein front panels 32 are removed from the plane of front frame 22 to permit access to whatever is disposed within drawer bodies 36 of drawers 30.

A locking stop 40 (FIGS. 1 and 4) is fixedly disposed on each drawer body 36 of each drawer 30 for coaction with a locking ear 46 carried by a locking bar 48 suitably disposed in casing 12 for longitudinal sliding movement in the directions of arrows A and B (FIG. 1); it being understood that there are lock stops 40 and locking ears 46 for each drawer 30 of cabinet 10.

A rib 52 (FIGS. 1, 3 and 4) is formed integral with and extending from lock bar 48 to form therewith a guide slot or channel 54 and a shelf 56 for coaction with an arm 62 of a connector-actuator 64 fulcrumed by forked legs 66 on a fulcrum lug 72 struck from an inner support wall 74 (FIGS. 1, 2 and 3) fixedly secured to right side wall 18 and front frame 22 of casing 12.

A lock mounting and guide channel 76 (FIGS. 2 and 4) also formed from inner support wall 74 slidably receives the body 80 of a conventional key-controlled rotary barrel lock 82 for movement in the direction of arrows C and D between locked (FIG. 3) and unlocked (FIG. 4) positions.

A shoulder 84 (FIGS. 2 and 3) is formed on guide channel 76 for coaction with a bolt 86 (FIGS. 1 and 3) of lock 82 which is normally urged to an extended position by conventional means (not shown) and which may be withdrawn to a retracted position (FIG. 4) by rotation of a barrel 88 (FIG. 2) of lock 82 through the use of a suitable key (not shown). A stop 98 (FIG. 2), also struck from inner support wall 74, determines the extent of movement of lock 82 in the direction of arrow C (FIG. 2).

A slot 94, formed in lock 82. is spanned by a pivot pin 96 (FIG. 2) adapted to receive a hook shaped pivot lip 98 (FIG. 3) formed on connector-actuator 64.

A plurality of lugs 182 (FIG. I) extend out from actuator 64 to space same from the inner surface of side wall 18 of casing 12 while an anchor lug 184 (FIGS. 3 and 4) also formed on connector-actuator 64 anchors one end of an actuator spring 186, the other end of which is anchored to inner support wall 74 as at 168. Spring 1116 urges connector-actuator 64 in the clockwise direction (FIG. 4) about fulcrum lug 72 urging, through arm 62 of connector-actuator 64 and shelf 56 of locking bar 48, locking bar 48 in the direction of arrow A and, through pivot lip 98 of connector-actuator 64 and pivot pin 96 of lock 82, lock 82 in the direction of arrow D.

To assemble lock 82 and connector-actuator 64 within cabinet 10 (lock bar 48 having been disposed therein in substantially conventional manner during the assembly of other parts of cabinet 10) the assembler need only slide lock 82 into lock mounting and guide channel 76;

place forked legs 66 of connector-actuator 64 upon fulcrum lug 72 of inner wall 74; insert hook shaped pivot lip 98 of connector-actuator 64 in slot 94 of lock 82 and about pivot pin 96 thereof; place arm 62 of connectoractuator 64 in guide slot 54 of locking bar 48; and anchor one end of spring 186 to anchor lug 104 of connectoractuator 64 and the other end of spring 186 to anchor lug 108 of inner support wall 74.

It should be noted that due to manufacturing tolerances required in the fabrication of the parts for cabinet 18 that some space will exist between the periphery of front panel 32 of drawer 30 and front frame 22 of casing 12, as more clearly shown in FIG. 5. To prevent insertion of a thin element such as the blade 110 of a knife (FIG. 5) by unauthorzied personnel there is formed in inner support wall 74 a plurality of spaced ribs 112, 114 (FIGS. 2 and 5) such that when knife blade 118 is inserted between front panel 32 of drawer 3'0 and front frame 22 of casing 18 it will be deflected and thus impossible to insert same into a position to lift locking bar 48 from its locked position as shown (FIGS. 1 and 3).

It should be further noted that due to manufacturing tolerances or for other reasons it may be desirable to attach a spring (not shown) to locking bar 48 to urge same in the direction of arrow B to thus facilitate movement thereof to its locked position.

When cabinet 10 is in its locked condition the elements of the locking mechanism are disposed as shown in FIGS. 1 and 3: with lock 82 in its locked position with bolt 86 thereof latched behind shoulder 84 of lock mounting and guide channel 76 of inner support wall 74; connector-actuator 64 in its actuated condition; and locking bar 48 lowered to its locking position with locking ears 46 thereof disposed in the paths of movement of locking stops 40 of drawers 30, thus preventing movement of front panels 32 of drawers 38 from their positions in the plane of front frame 22 of casing 12, and access to drawer bodies 36.

To unlock cabinet 18 and permit opening of the drawers 38 thereof one need only insert an appropriate key (not shown) in barrel 88 of lock 82 and rotate same in the direction to withdraw bolt 86 of lock 82 to its retracted position (FIG. 4). Spring 186, immediately upon retraction of bolt 86, acts on connector-actuator 64 to rock same in the clockwise direction (FIGS. 3 and 4) about fulcrum lug 72 and through the coaction of hook shaped pivot lip 98 of connector-actuator 64 and pivot pin 96 of lock 82 to move lock 82 in the direction of arrow D" (FIG. 2) from its locked position (FIG. 3) to its unlocked position (FIG. 4). As connector-actuator 64 rocks in the clockwise direction arm 62 thereof acts on shelf 56 of rib 52 to move locking bar 48 in the direc tion of arrow A (FIG. 1) from its lowered or locking position (FIG. 3) to its raised or unlocking position (FIG. 4) wherein locking ears 46 of locking bar 48 are removed from the paths of movement of locking stops 40 of drawers 30, thus permitting movement of drawers 38 and of front panels 32 thereof from the plane of front panel 22 of casing 12.

To lock cabinet 18 one need only apply suitable force against lock 82 to move same in the direction of arrow C (FIG. 2) until bolt 86 thereof is free of channel 76 and moved to its extended position (FIGS. 1 and 3) by appropriate mechanism (not shown) behind shoulder 84 of inner support wall 74. The coaction between pivot pin 96 of lock 82 and pivot lip 88 of connector-actuator 64, during movement of lock 82 in the direction of arrow C, results in a counterclockwise rocking (FIGS. 3 and 4) of connector-actuator 64 about fulcrum lugs 72 and against the action of spring 186. As arm 62 of rocking connector-actuator 64 moves away from shelf 56. of rib 52 of locking bar 48, locking bar 48 moves in the direction of arrow B (FIG. 1) under force of gravity until blocking ears 46 of locking bar 48 are disposed in the paths of movement of locking stops 40 of drawers 30 and movement of drawers 30, and of front panels 32 of drawers 3t from the plane of front frame 22 of casing 12 is prevented.

Should any drawer 30 be in a position with front panel 32 thereof out of the plane of front frame 22 of casing 12, when lock bar 48 is in its locking at lowered position (FIGS. 1 and 3) its locking stop 40 will not be located behind its respective locking ear 46 and movement thereof is possible. Movement of such a drawer 30 to place its front panel 32 in the plane of front frame 22 of casing 12 results in a coaction between its locking stop 40, which is disposed thereon in an inclined manner, and the appropriate locking ear 46 of locking bar 48 and a movement of locking bar 48 in the direction of arrow A (FIG. 1) until such locking stop 40 has moved past the path of travel of said locking ear 46 at which time, since arm 62 of connector-actuator 64 is still in its actuated (FIGS. 1 and 3) position, locking bar 48 again moves in the direction of arrow B (FIG. 1) until it assumes its locked position (FIGS. 1 and 3) with locking ears 46 in the paths of movement of locking stops 40 of drawers 30.

From the above description it will thus be seen thaat a novel and improved locking mechanism has been provided for securing one or more of a plurality of movable members against movement and is adapted for use in cabinets and the like and especially multiple drawer cabinet, which mechanism is inexpensive and simple in construction, requires a minimum of labor for installation, and does not require the use of intermediate connecting or attaching elements (such as bolts, screws, rivets, etc.) to enable installation and interconnection of the various elements of the locking mechanism.
