CABINET Filed July 19, 1965 F a M 5/36 INVENTOR OTTO LEWIN ail J/M ATTORNEY United States Patent Chico 3,325,234 Patented June 13, 1967 3,325,234 CABINET Otto Lewin, York, Pa., assignor to Cole Steel Equipment Co., Inc., New York, N.Y., a corporation of NewYork Filed July 19, 1965, Ser. No. 473,057 16 Claims. (Cl. 312--219) This invention relates to cabinets and more particularly to a locking arrangement for multipledrawer cabinets.

Multiple-drawer cabinets, such as those commonly used for filing or as pedestals for desks, are sometimes constructed with mechanism to lock the drawers thereof against being opened by unauthorized personnel, and are sometimes constructed without any form of locking mechanism whatsoever.

A very efiicient and commonly used form of locking mechanism incorporates a bar or slide disposed for rectilinear sliding movement, along either the side or back of the cabinet, in response to the actuation of a key controlled lock slideably disposed in the cabinet and interconnected with the bar or slide by suitable connecting means. The bar in turn coacts with stops provided on each drawer of the cabinet.

When a locking mechanism is incorporated in a multiple drawer cabinet it will usually affect the price thereof. Therefore, a purchaser who does not require a cabinet that locks, to save money, will purchase a cabinet which does not incorporate locking structure. The manufacturers, distributors, and dealers must therefore provide and stock multiple-drawer cabinets not only in many sizes and shapes for many purposes, but also with and without looking mechanisms.

If the purchaser knows in advance Whether he requires a lockable cabinet he can place his order with his dealer, Who can then place it with the manufacturer, and the cabinet appropriately constructed. However, quite often, either the purchaser does not foresee the need for locking mechanism in the cabinet, or the dealer does not have stock on uch a cabinet and must make an immediate delivery. It has therefore become common practice to field install locking mechanisms in file cabinets by securing stops to the drawers thereof, positioning a lock and actuator therewithin, and locating a locking bar in the cabinet for coaction with the drawer stops.

Field installation of the drawer stops is most always difficult, and so they are quite often provided on all drawers whether needed or not; with the manufacturer either taking the loss or passing it on to the purchaser when such stops are not needed.

Field installation'of the locking bar has however presented many problems. The internal construction of the cabinet almost always prevents the ready insertion of a bar of the length that the locking bar must be. Such locking bars must therefore either be provided in the cabinet whether needed or not, in which case the manufacturer must take a loss thereon or pass on the additional charge to the customer, or the cabinet must be somehow mutilated by opening either the bottom, top or side thereof to permit installation of the locking bar.

It is therefore an object of this invention an improved cabinet.

It is a further object to mechanism for a multiple to provide provide an improved locking drawer cabinet.

A still further object is to provide a locking mechanism which can be efficiently field installed in a multiple drawer cabinet.

Another object is to provide a locking mechanism which can be field installed in a multiple drawer cabinet without mutilation of any part of the cabinet, and which is easily adaptable for use with cabinets having different numbers of drawers.

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 position and a locked position through 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 providing drawer stops, a lock, a connecting member, and a locking bar which can be field installed in a cabinet not provided with such mechanism in an efficient manner, with a minimum of effort and cost, and without mutilation of the cabinet.

In carrying out the invention, according to preferred embodiment thereof, the cabinet itself has formed therein during the fabrication thereof, structure for receiving a lock and for guiding the movement thereof, and for receiving a connector-actuator which interconnects the lock and the locking bar; while the drawers are formed to receive locking stops. The lock and connector-actuator are adapted for ready insertion into the file cabinet without the use of special tools and without the use of the intermediate connecting mean such as screws, bolts, nuts, welding, etc. and when inserted in the file cabinet, for ready interconnecting one with the other; while the locking bar is formed in several sections adapted to be easily disposed in guide means provided in the cabinet and once so disposed readily interconnected by simple and efiicient connecting means. The locking stops and drawer structure for receiving same are constructed such that the locking stops may be installed on the drawer without the use of intermediate connecting means (such as bolts, screws, nuts, welding or riveting) and once so installed so that they cannot be easily removed.

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

In the drawings:

FIG. 2 is an enlarged fragmentary front elevational view of a section of the locking bar of FIG. 1; 7 FIG. 3 is a side elevational view of the enlarged fragmentary showing of the locking bar of FIG. 2;

FIG. 4 is a sectional view taken on line 4-4 of FIG. 2;

FIG. 5 is an exploded and enlarged fragmentary perspective view, in partial section of the locking stop of FIG. 1;

FIG. 61s a sectional view taken on line 6-6 of FIG. 1; and

FIG. 7 is a sectional view taken on line 7-7 of FIG. 2.

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 multiple 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 to be provided with a locking mechanism to secure such drawers against movement by unauthoried personnel to said position exposed from the confiines of the cabinet.

With reference to FIG. 1 there is shown generally at 10 a file cabinet of the kind commonly used for the purpose of storing papers, reports, and the like and consisting of a casing 12 formed with a top wall 14, a rear wall 16, a right-side wall 18, a left-side wall 20, and front frame 22, and within which are slideably disposed drawers 30, each including a front panel 32 supporting a drawer handle 34 and supported by a drawer body 36.

Suspension mechanism 40 (FIG. 1) 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 bodies 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.

A pair of guides 50 (FIGS. 1, 5 and 6) and 52 (FIGS. 1 and 5) are formed on the side of each drawer body 36 so as to provide guide channels 54 and 56 and lanced projections 58 (FIGS. 1, 5 and 6) and 60 (FIG. 5) re- 'spectively.

A pair of legs 70 (FIGS. 1, 5 and 6) and 72 (FIG. 5), adapted for disposition respectively in guide channels 54 and 56, and carried by a locking stop 74 are each formed with a bent over tab, 76 and 78 respectively, at one end thereof, and with an aperture, 80 and 82 respectively adapted to receive lanced projections 58 and 60 respectively.

To install locking stop 74 on drawer 30 one need only align the bent over tabs 76 and 78 with guide channels 54 and 56 respectively and then apply pressure against locking stop 74 to move same in the direction of arrow A (FIG. 5) until locking stop 74 is seated as shown in FIGS. 1 and 6. When so seated the lanced projections 58 and 60 will be disposed in apertures 80 and 82 (FIG. 6) and locking stop 74 will be secured to drawer body 36 in position for coaction with a locking ear 90 carried by a locking bar 92 suitably disposed in casing 12 for longitudinal sliding movement in the directions of arrows B and C (FIG. 1) and guided in such movement by a plurality of spaced guides 96 (only once shown in FIG. 1) formed with openings 98 and suitably secured in casing 12; it being understood that there is a locking ear 90 and a locking stop 74 for each drawer '30 of cabinet 10.

Locking bar 92 is assembled from a plurality of intermediate bars 100a and 10% each formed with an aperture, 102a (FIG. 1) and 102b (FIGS. 1 and 2) respectively disposed near the upper ends thereof, and an embossment, 104a (FIGS. 1 and 2) and 1041) (FIG. 1) respectively formed near the lower ends thereof and adapted for disposition in apertures 102a, 102b respectively; a lower bar 106 (FIG. 1) formed with an aperture 108 adapted to receive embossment 10411 of intermediate bar 10%; and an upper bar 110 formed with embossment 112 adapted to be disposed in aperture 102a of intermediate bar 100a. An upper securing hole 116a (FIG. 1) and 116b (FIGS. 4 and 7) is formed in intermediate bars 100a and 10Gb respectively while an upper securing hole 118 is formed in a lower bar 106. A pair of lower securing holes 120 (FIG. 4) are formed in intermediate bar 100a while similar pairs of lower securing holes (not shown) are formed in intermediate bar 10% and upper bar 110. A pair of spring legs 132 (FIGS. 2 and 7) and 134 struck from spring clip so as to be normally urged apart from each other, are adapted to be squeezed together and moved through aligned lower securing hole 120 of intermediate bar 100a and upper securing hole 116b of intermediate bar 1001) and to then spread apart to provide the interconnection for intermediate bars 100a and 10012 to each other. In the same manner,

spring legs

132 and 134 of another spring clip 130 are disposed in lower securing hole 120 of intermediate bar 10% and upper securing hole 118 of lower bar 106, as well as in lower securing hole 120 of upper bar 110 and upper securing hole 116a of intermediate bar 100a to provide the interconnection for intermediate bar 1001: and lower bar 106 and for intermediate bar 100a and upper bar 110 respectively. p

A necked down portion (FIG. 1) is formed on intermediate bars 100a and 100b, upper bar 110, and lower bar 106 to facilitate the disposition of such bars in guide slots 98 of guides 96.

A ri'b 152 (FIG. 1) is formed integral with and extending from locking bar 92 to form therewith a guide slot or channel 154 and a shelf 156 for coaction with an arm 162 of a connector-actuator 164 fulcrumed by forked legs 166 on a fulcrum lug 172 struck from an inner support wall 174 fixedly secured to right side wall 18 and front frame 22 of casing 12. A slot 176 is formed in inner support wall 174 to facilitate the disposition of arm 162 of connector-actuator 164.

A substantially conventional key-controlled rotary barrel lock 180 is mounting for sliding movement in the direction of arrows D and E in a lock mounting channel (not shown) formed also in inner support wall 174, and is pivotally connected, as at fulcrum 182, to connectoractuator 164. A plurality of lugs 186 (FIG. 1) extend out from connector-actuator 164 to space same from the inner surface of side wall 18 of casing 12. An anchor lug 188, also formed on connector-actuator 164, receives one end of an actuator spring 190 the other end of which is anchored to inner support wall 174 as at 192. Spring 190 normally urges connector-actuator 164 in the counterclockwise direction (FIG. 1) about fulcrum lug 172 urging, through arm 162 of connector-actuator 164 and shelf 156 of locking bar 92, locking bar 92 in the direction of arrow C; and, through pivotal connection 182 of connector-actuator 164 and lock 180, lock 180 in the direction of arrow E.

A spring 200 having one end thereof anchored to a lug 202 disposed on lower bar 106 and the other end thereof secured within casing 12 urges assembled locking bar 92 in the direction of arrow B to maintain shoulder 156 of upper bar 110 in engagement with arm 162 of connector-actuator 164.

To install a locking mechanism (FIG. 1) in a cabinet 12 not equipped with such mechanism but provided with fulcrum lug 172, a channel for mounting lock 180, and guides 96, one first installs lock 180' in it's guide channel by providing a suitable aperture in front panel 22 by either cutting the metal away, or if front panel 22 is provided with a knock-out plug, removing such knockout plug. With drawer 30 removed, the installation of connector-actuator 164 is accomplished by sliding spaced forked legs 166 thereof through slot 176 of inner support wall 174, positioning legs 166 on fulcrum 172, and pivot-' ally interconnecting connector-actuator 164 to lock 180 through the intermediary of fulcrum 182. Connector-actuator 164 is then held in engagement with fulcrum 182 of lock 180 so as to move lock 180 in the direction of arrow E, to its unlocked position, and one end of spring 190 is anchored to inner support wall 174 as at 192 and the other end of spring 190 is disposed on anchor lug 188 of connectonactuator 164. Necked-down portion 140 of upper bar 110 is then maneuvered into opening 98 of its guide 96 and shoulder 156 of upper bar 110 disposed on arm 162 of connector-actuator 164. Intermediate bar 1000 is then installed by maneuvering necked-down portion 140 thereof into its opening 98 of its respective guide 96, inserting embossment 112 of upper bar 110' into aperture 102a of intermediate bar 100a, aligning upper securing hole 116a of intermediate bar 100:; wit-h one of the lower securing holes 120 of upper bar 110, and then pushing

legs

132 and 134 of spring clip 130 into aligned holes 116a and 120 until spring clip 130 seats therein to interconnect upper bar 110 and intermediate bar 100a. Neckeddown portion 140 of intermediate bar 1001) is next maneuvered through opening 98 of its respective guide 96 and aperture 10212 thereof disposed over em'bossment 104a of intermediate bar 100a. Upper securing hole 116!) of intermediate bar is then aligned with lower securing hole 120 of intermediate bar 100a and

legs

132 and 134 of spring clip 130 inserted therethrough to secure intermediate bar 1011b to the assembled intermediate bar 100a and upper bar 110. Lower bar 106 is then installed by placing aperture 108 thereof over embossment 104b of intermediate bar 100b, aligning upper securing hole 118 thereof with lower securing 'hole 120 of intermediate bar 100b, and inserting

legs

132 and 134 of spring clip 130 through aligned upper hole 118 of lower bar 106 and lower securing hole 120 of intermediate bar 10%. Spring 200 is thereafter anchored to lug 202 of lower bar 106 and to casing 12 urging assembled locking bar 92 in the direction of arrow B and shelf 156 of bar 92 into engagement with arm 162 of connector-actuator 164.

Movement of lock 180 in the direction of arrow D, through its pivotal connection 182 with connector-actuator 164, results in a clockwise rotation (FIG. 1) of conhector-actuator 164 about fulcrum lug 172 and against the action of spring 190, moving arm 162 of connectoractuator 164 away from shelf 156 of assembled locking bar 92 and permitting movement of locking bar 92 in the direction of arrow B under bias spring 200 and/or gravity.

Conventional structure is provided with lock 180 to secure same in a locked condition (FIG. 1) upon movement of lock 180 to its fullest extent in the direction of arrow D. Such securing structure is released through the use of a suitable key and when so released the action of spring 190 upon connector-actuator 164, urging same in the counterclockwise direction (FIG. 1) about fulcrum lug 172, and the resultant action of connector-actuator 164 upon lock 180, through the intermediary of pivot 182, moves lock 180 in the direction of arrow B from its locked condition to its unlocked condition. counterclockwise rotation of connector-actuator 164, through the coaction of arm 162 thereof with shelf 156 of locking bar 92, also moves locking bar 92 in the direction of arrow C against gravity and/or the action of spring 200 to re- "move locking ears -90 of locking bar 92'from the path of movement of locking stops 74 of drawers 30.

Stops 74 are installed on drawer bodies 36 as previously described by inserting legs 70 and 72 thereof into guide channels 54 and 56 respectively until lanced projections 5'8 and 60 of

guides

50 and 52 are lodged in apertures 80 and 82 respectively. Drawers 30 are then reinstalled in casing 12 with locking ears 90 of locking bar 92 out of the path of movement thereof.

The locking of cabinet 10 is thereafter accomplished by moving lock 180 in the direction of arrow D and the subsequent movement of locking bar 92 in the direction of arrow B to place locking ears thereof in the paths of movement of locking stops 74; while the release of drawers 30 is accomplished 'by the unlocking of lock 180 and the movement thereof, in the direction of arrow E, and of locking bar 92 in the direction of arrow C.

The bars 110, 106, a and 1001) are formed so that only upper bar and lower bar 106 are required for use with a conventional two-drawer file cabinet. While for each additional drawer provided in the cabinet one intermediate bar 100 is inserted therebetween.

The pair of lower securing holes are provided to permit installation of a locking bar 90 in a cabinet 10 with a different spacing between its drawers 30; it being understood that any number of such holes or even a slot may be provided for such function if desired.

The various bars of locking bar 92 may of course be interconnected through the use of means other than spring clips (such as bolts, rivets, etc.) if so desired, and locking stops 74 may either be inserted in

guides

50 and 52 from the bottom as shown in the figures, from the top, or they may be permanently provided on the drawers if so desired.

In addition it should of course be obvious that While locking bar 92 has been shown formed with a rib 152 and with a shelf 156 that hangs upon an arm 162 of connector-actuator 164 that locking bar 92 may be pivotally interconnected with connector-actuator 16 by other appropriate means (such as a rivet, bolt, or spring clip), and that the locking mechanism hereof is easily adapted for use with other types of locks and actuators and for disposition along either the side walls front wall, or rear wall of casing 12.

From the above description it will thus be seen that a novel and improved locking mechanism has been provided for a multiple drawer cabinet, which permits manufacture of a cabinet with lock receiving structure (lock guide, fulcrum lug, locking bar guides, locking stop guides, etc.) which, although minimal, inexpensive, and casting little if any burden upon the manufacturer and therefore the purchaser, readily and eificiently receive a locking mechanism without mutilation of the cabinet (except possibly to provide an aperture for the lock), because the locking bar is formed in sections which can be easily maneuvered into position within the cabinet and then interconnected to form a unitary locking bar, and be cause the locking stops can be securely attached in proper position on the drawers.

It is understood that although I have shown the preferred form of my invention that various modifications may be made in the details thereof without departing from its scope as comprehended by the following claims.
