A lateral file cabinet has drawers that extend from the long side (various lengths) of the cabinet. These are also called side filers in Great Britain. There are also shelf files, which go on shelves.  To open a drawer on most metal filing cabinets, a small sliding mechanism known as a "thumblatch" must be pressed to release and open the drawer. Each drawer has a handle to grip and pull the drawer with. On the front face of each drawer, there is usually a label holder to allow the user to identify the contents of the drawer. Many file cabinets incorporate a keyed lock to prevent unauthorized access to the documents being stored. There are two types of locks. A "cam lock" is activated with a key that rotates the lock. ownCloud’s new transactional file locking mechanism operates differently than the old File Locking application, and will eventually replace it. The purpose of this mechanism is to avoid file corruption during normal operation. If you select to use the new file locking mechanism make sure you disable the File Locking app. The new file locking mechanism has these capabilities: Operates at a higher level than the filesystem, so you don’t need to use a filesystem that supports locking. Locks parent directories so they cannot be renamed during any activity on files inside the directories. Releases locks. The Sequel is a modern locking file cabinet that offers ample storage, and is a convenient and stylish solution for organizing office supplies and important files, whether as a standalone piece or as the base for a Sequel workspace.  For security, an anti-tip mechanism allows only one drawer to be opened at a time.

Interlocks for file cabinets that prevent more than one drawer from being opened at a given time include an elongated, flexible member, such as a cable, which is changeable from a high slack condition to a low slack condition when one of a number of associated drawers is opened.

In the low slack condition, the interlocks prevent their associated drawers that are closed from being opened. In the high slack condition, which exists when lateral file cabinet locking mechanism failed drawers are closed, the interlocks allow their associated drawers to be opened. The interlocks may be used in conjunction with a lock that selectively changes the cable from a high slack condition to a low slack condition and vice versa.

The interlocks may be constructed to exert a force on the cable that is a small fraction of the pulling force llcking on a locked drawer.

This application claims priority to commonly assigned U. Provisional Application Ser. Lateral file cabinet locking mechanism failed present invention relates to filing cabinets, and more particularly to mechanisms fxiled to prevent one or more of the drawers in the filing cabinet from being opened.

It has been known in the past to include interlock mechanisms on filing cabinets that prevent more than one drawer in the cabinet from being opened at a single time. These interlock mechanisms are generally lateral file cabinet locking mechanism failed as safety features that are intended lateral file cabinet locking mechanism failed prevent the filing cabinet from accidentally falling over, a condition that may be more likely to occur when more than one drawer in the cabinet is open.

By being able to open only a single drawer at a given time, the ability to change the weight distribution of the cabinet and its contents is reduced, thereby diminishing the likelihood that the cabinet will fall over.

In addition to such interlocks, past filing cabinets have also included locks that prevent any drawers from being opened when the lock is moved to a locking position. These locks are provided to address security issues, rather than safety issues. These locks override the interlocking system so that if the lock is activated, no drawers may be opened at all. If the lock is not activated, the interlock system functions to prevent more than one drawer from being opened at the same time.

Oftentimes the system that locks all of the drawers and the interlock system that locks all but one of the drawers are at least partially combined. The combination of the locking system with the interlocking system can provide cost reductions by utilizing common parts. Past locking and interlocking mechanisms, however, have suffered from a number of disadvantages.

One disadvantage is the difficulty of changing the drawer configurations within a cabinet. Many filing cabinets are designed to allow different numbers of drawers to be housed within the cabinet. For example, in the cabinet depicted in FIG. For some cabinets, it would be possible to replace these three drawers with another number of drawers having the same total height as the three original drawers.

This reconfiguration of the drawers is accomplished by removing the drawer slides on each side of the drawer and either repositioning the drawer slides at the newly desired heights, or installing new drawer slides at the new heights. Many drawer slides include bayonet features that allow the drawer slides to be easily removed and repositioned within the cabinet. For example, U. The height of these rods must be chosen to match the vertical spacing between each of the drawers in the system.

If the cabinet is to be reconfigured, then new rods will have to be installed that match the height of the new drawers being installed in the cabinet. Not only does this add additional cost to the process of reconfiguring the lateral file cabinet locking mechanism failed, it complicates the reconfiguring process by requiring new parts of precise dimensions to be ordered.

Another difficulty with systems like that disclosed in the Sawatzky patent is the precise manufacturing that may be required to create these rigid rods. These interlock systems only work if the rods have heights that fall within a certain tolerance range. This tolerance range, however, decreases as more interlocks are installed in a given cabinet. In other words, the tolerance of the heights of these rods is additive.

In order to function properly, a cabinet with ten drawers will therefore require smaller tolerances in the rods than a two drawer cabinet. In order to create rods that can be universally used on different cabinets, it is therefore necessary to manufacture the rods within the tight tolerances required by the cabinet having the greatest expected number of drawers. Fakled tight tolerances tend to increase the cost of the manufacturing process.

Another difficulty with past interlock and lock systems for file cabinets has been the expense involved in creating a locking system that will withstand high forces lateral file cabinet locking mechanism failed on the drawers. Thus, if a file cabinet does not exceed this standard, thieves can gain access to the contents Lateral File Cabinet Locking Mechanism Java of a lock drawer by pulling the drawer outwardly with more than fifty pounds of force. Many users of file cabinets, lateral file cabinet locking mechanism failed, desire their locking system to be able to withstand much greater forces than this before failure.

Increasing the durability of the locking system often adds undesired expense to the cost of building the system. A number of prior art interlock systems have used cables or straps as part of the interlocking system. Such systems, however, have suffered from other disadvantages. The slack in the cable is decreased when a drawer is opened. Lateral file cabinet locking mechanism failed amount of slack of the cable is carefully chosen during the installation of the drawer lock so that there is just enough in the lateral file cabinet locking mechanism failed to allow only one drawer to be opened at a time.

The interlock on whatever drawer is opened takes up this available slack in the cable, which prevents other drawers from being opened at the same time. A similar system is disclosed in U. This system uses a strap instead of a cable. Failef systems suffer from the fact that excessive amounts of force may be easily transferred to either the cable or the strap.

In other fabinet, the cable or the strap itself are what resist the pulling force that a person might exert on a closed drawer when either the lock is activated, or another drawer is opened. The tensile strength of the lateral file cabinet locking mechanism failed or strap therefore determines how much force must be exerted to overcome the interlock or lock.

In fact, in the interlock of Westwinkel, the system appears to be constructed so that the vile force exerted by a person on a locked drawer will be amplified before being applied to the strap. The strap must therefore have a greater tensile strength than the highest rated pulling force that the lock or interlock system can resist. Increasing the strength of the cables or straps typically tends to increase their cost, which lateral file cabinet locking mechanism failed desirably avoided.

In light of the foregoing, the desirability of an interlock and lock system that overcomes these and other disadvantages can be seen. Accordingly, the present invention provides an interlock and lock that reduces the aforementioned difficulties, as well as other difficulties.

The interlock and lock of the present invention allow relatively low-tensile strength cables or flexible members to be used in systems which provide high resistance to theft and breakdown. The system of the present invention further allows changes to lzteral configurations to be easily implemented with little or no additional work required to integrate the new cabinet configuration into the interlock or lock system.

The present invention provides a simple construction for locks and interlocks that can be easily manufactured without excessively restrictive tolerances, and which can be easily installed in cabinets. According to one aspect of the present invention, an interlock cabinwt a cabinet drawer is provided.

The drawer is movable in the cabinet is a first direction toward an open position and in a second, opposite direction toward a closed position. The interlock includes an elongated, flexible member, a rotatable lever, an engagement member, and a biasing member. The lever is adapted to alter the amount of slack in the elongated, flexible member. The latral is rotatable between a first position and a second position.

The first position creates a low amount of slack in the elongated, flexible member, and the second position allows a high amount of slack to be present in the elongated, flexible member. The engagement member is attached to the caninet and positioned to cause the rotatable lever to rotate toward the first position when the drawer is initially moved from the closed position in the first direction.

The biasing member is positioned adjacent the lever and adapted exert a biasing force that tends to prevent the lever from rotating from the first position to the second position until the drawer is moved in the second direction to the closed position.

According to another aspect of mchanism present invention, an interlock is provided. The interlock includes a cable, a rotatable lever, an engagement member, and a retainer. The lever is adapted to change the cable between high and low slack conditions.

Lateral file cabinet locking mechanism failed engagement member is attached to the drawer and positioned to cause the loccking to rotate to a first position that changes the cable to a low slack condition when the drawer is initially moved in the first direction from the closed position. The engagement member is also positioned such that a first force exerted on the drawer in the first direction is translated by the lever to a second force on the cable, which is less than the first force.

The retainer is adapted to retain the rotatable lever in the first position lockinb the drawer is moved to the open position. According to still another aspect of the present invention, a locking and interlocking system for a cabinet is provided. The system includes a lock, a first cable, a second cable, a first interlock, and a second interlock.

The first cable extends between faled least a first and second drawer. The first cable is changeable from a high slack to a low slack condition. The second cable extends between the lock and the first drawer. The lock is adapted to change the second cable from a high slack to a low slack condition. The first interlock is in communication with the first and second cables and adapted to change both said first and said second cables from the high slack to the low slack condition whenever the mechamism drawer is opened.

The first interlock is further adapted to prevent the first drawer from opening whenever the first or second cables are in the low slack condition. The second interlock is in communication with the first cable and adapted to change the first cable from the high slack to the low slack condition whenever the second drawer is opened.

The second interlock is further adapted to prevent the second drawer from opening whenever the first cable is in the low slack condition. According to yet another aspect of the present invention, a cabinet is provided that includes at least one drawer movable within the cabinet in a first direction toward lateral file cabinet locking mechanism failed open position and in a second, opposite direction toward a closed position. The cabinet further includes a frame adapted to support the drawer, an elongated, flexible member, an interlock, and a slack take up mechanism.

The elongated, flexible member is positioned within the cabinet and changeable between a lower slack condition and a higher slack condition. The interlock is positioned within the frame and in operative engagement with the elongated, flexible member. The interlock is adapted to prevent the drawer from moving to the open position when the elongated, flexible member is in the lower slack condition and to allow the drawer to move to the open position when the elongated, cabiinet member is in the higher slack condition.

The slack take up mechanism is adapted to change the elongated, flexible member laterzl the lateral file cabinet locking mechanism failed slack condition to the lateral file cabinet locking mechanism failed slack condition when the lateral file cabinet locking mechanism failed is moved from the closed position to the open position.

The slack take up mechanism is further adapted to translate a first force exerted on the drawer in the first direction to a second force exerted on the elongated, flexible member which is less than the first lateral file cabinet locking mechanism failed. According to still other aspects laterla the present invention, the interlock may be in communication with a lock that is adapted to selectively alter the condition of the cable.

The interlocks may be secured to drawer slides that are removable from the cabinet. A cable guide may be included as part of the interlock to snap-fittingly receive the cable and retain it in engagement failex the interlock. The various aspect of the present invention provides an interlock and lock system that is versatile, flle to high forces, and easily installed.

These and other benefits of the present invention will be apparent to one skilled in the art in light of the following written description when read in conjunction with the accompanying latteral.
