A self-locking mechanism for use with a locking barrier on a cabinet. The locking mechanism includes an actuator and one or more locking members for securing the locking barrier in a closed position. When the locking barrier lateral file cabinet locking mechanism version in an open position, a detent element holds one of the locking members and the actuator in an unlocked position.

A projection attached to lateral file cabinet locking mechanism version cabinet disengages the detent element upon closing of the locking barrier, thus allowing the locking member to extend lateral file cabinet locking mechanism version its locked position.

More particularly, the present invention relates to a self-locking mechanism for use with a lock bar on a cabinet, such as a cabinet adapted to contain pharmaceuticals and supplies. Lateral file cabinet locking mechanism version pharmaceutical cabinets and carts are widely used in hospitals and other medical care facilities.

Keeping pharmaceutical products secure from unauthorized access is a matter of major concern in medical care facilities, not only to protect against theft and misuse of the pharmaceuticals but also to comply with legal requirements concerning controlled substances.

Security of pharmaceutical carts used for delivering and dispensing pharmaceutical substances Lateral File Cabinet Locking Mechanism English are of particular concern since the lateral file cabinet locking mechanism version are of necessity used in areas where they are within easy reach of patients and other non-medical personnel. It is a general requirement in hospitals and the like that pharmaceutical carts be locked when not attended by an authorized person.

One important advance in such cabinets is the use of a locking bar. Such locking bars are disclosed in U. These patents disclose a multiple drawer cabinet having a lockable vertically extending locking bar external to the cabinet and pivotally attached to one edge thereof.

The locking bar, in its locked position, extends along the front of several drawers to obstruct their movement. This vertical locking bar cooperates with a plurality of horizontal locking bars to selectively allow and prevent removal of bins or drawers from a plurality of shelves of a cabinet.

The arrangement disclosed in these patents allows a plurality of bins or drawers to be locked in place by pivoting the locking bars into a locked position without the need for providing individual locks on lateral file cabinet locking mechanism version bins or requiring that the bins be contained within a lockable drawer or the like.

Furthermore, the bins may be readily removed by unlocking the vertical locking bar, which will allow for free rotation of the horizontal locking bars, providing lateral file cabinet locking mechanism version convenient removal of the bins individually.

Although providing a substantial improvement in the art, the cabinets disclosed in those patents did not provide for automatic locking of the vertical lock bar. The lock bar of these patents had to be lateral file cabinet locking mechanism version locked once closed.

Thus, a potential problem is that medical personnel might remember to close the lock bar, but then forget to lock the lock bar once the lock bar was in the closed position. Therefore, there is a need in the art for an improved locking barrier for use on such cabinets that automatically locks upon closing.

In one aspect of the present invention, a locking mechanism is provided that has self-locking ability. The locking mechanism includes one or more locking members moveable between a locked position and an unlocked position, and a detent element engaging the locking member when the locking member and the detent element are in an unlocked position.

The detent element is biased towards the unlocked position, and the detent element lateral file cabinet locking mechanism version moveable to a locked position where the detent element does not engage the locking member. The locking mechanism also includes an actuator connected with the one or more locking members, the actuator capable of movement between a locked position and an unlocked position.

The actuator is biased towards the locked position, and the actuator is adapted to move the one or more locking members to the locked position in response to the movement of the detent element to its locked position.

In another aspect of the invention, a locking barrier is provided that uses a locking mechanism having automatic locking capacity. The locking barrier includes a barrier housing having one or more locking members within the housing which are moveable between a locked position and an unlocked position. The locking barrier also includes a detent element within the housing that engages the locking member when the locking member and the detent element are in an unlocked position.

The detent element is biased to the unlocked position, but is moveable to the locked position where the detent element does not engage the locking member. The locking barrier also includes a first actuator rotationally mounted within the housing and connected with the one or more locking members. The actuator is capable of rotation between a locked position and an unlocked position and is biased towards the locked position.

The actuator is adapted to move the one or more locking members to their locked position in response to the movement of the detent element to its locked position. In yet another aspect of the invention, a cabinet is provided that utilizes a locking barrier that includes a self-locking mechanism. The cabinet includes a cabinet housing and a plurality of bins within the cabinet housing. The bins are moveable between a closed position and open positions.

An actuating member is attached to the cabinet housing. A locking barrier is also connected with the cabinet housing and is moveable between a closed position and open positions. The locking barrier is adapted to secure the bins in their closed position when the locking barrier is in its closed position, while allowing the bins to move to their open positions when the locking barrier is in an open positions.

In addition, the locking barrier includes a locking mechanism. The locking mechanism includes one or more locking members capable of activating to thereby lock the locking barrier in its closed position.

A contact portion of the locking mechanism is configured so as to contact the actuating member when the locking barrier is in its closed position. The locking mechanism and the actuating member cooperate to activate the locking member in response to movement of the locking barrier from an open position to its closed position. Other aspects of the invention will be apparent to those skilled in the art in view of the following detailed description of the preferred embodiments, along with the accompanying drawings.

Referring now to the accompanying drawings and initially to FIG. With the exception of the locking mechanism and the locking barrier as described in detail belowthe cabinet of the preferred embodiment is substantially similar to the cabinets disclosed in U.

In the preferred embodiment as shown, the cabinet [] is a segmented side wall pharmaceutical cabinet having a housing including a top surface and a base The cabinet is provided with casters and may be used as a pharmaceutical dispensing cart. The cabinet housing further includes a base side wall segmentmiddle side wall segments and a top segment It is provided with a plurality of drawers for containing various items and a plurality of pharmaceutical cassetteseach containing a plurality of bins Each of the cassettes comprises two rows of bins disposed in a side-by-side relation, and is slidably removable from cabinet Each of the cassettes is further provided with a horizontally extending bin locking barrier extending frontally along a lower portion of an upper row of bins and an upper portion of a lower Hon File Cabinet Locking Mechanism Model row of bins.

The bin locking barriers have an elongated cross section and are rotatable between a horizontal releasing position allowing for removal of individual ones of the bins and a vertical locking position in which removal of the bins is restrained.

A vertically extending lateral file cabinet locking mechanism version locking barrier [] is hingedly attached to one side of cabinet by a hinge and is rotatable between a locked position as shown in FIG.

In the embodiment shown, the locking barrier is formed as a lock bar, but those skilled in the art will appreciate that in other embodiments the locking barrier could be formed as a door, shield, or other barrier having a locking mechanism.

When in the locked position, as shown in FIG. The details of the structure and operation of the cassettesbinsand horizontally extending bin locking barriers are described in detail in Lateral File Cabinet Locking Mechanism Statistics the above referenced patents. The locking barrier [] includes a rotatable handle for opening for the locking barrier When the locking barrier is locked, the handle is only rotatable after unlocking the locking barrier using the key core or the key button pad The locking mechanism is disposed within the locking barrier housing defined by front panela spaced rear panela bottom capand a top bracket and a detent housing The locking mechanism includes locking members defined by an upper locking pin and a lower locking pin Locking pins and are oriented so as to move in substantially parallel but opposite directions.

Locking pins andwhen in an extended position as shown in FIG. When locking pins and are in lateral file cabinet locking mechanism version retracted position as shown in FIG.

The locking pins [] and are connected to an actuator disk at lateral positions thereof. The actuator disk is rotatable about an axle assembly FIG.
