drawer-lock-mechanism-procedure I used a cap from a pill case. To achieve this motion conversion, the actuator includes the slot 56 which includes a top horizontal slot portion 57 and a bottom horizontal slot portion 59 connected by a slanted camming locm portion 58 that transitions between the top and bottom horizontal slot portion. Now it is time to attach the drawer to drawer lock mechanism procedure table. Also drawer lock mechanism procedure prevent theft. Seat track apparatus.

This keeps the glass door from sliding. A ratchet lock is used on glass doors and has a bar that slides back and forth.

The way the lock slides depends on which way the door slides. The bar will block the door from opening. This saves the facility manager time and money if one of the locks were to break.

Cabinet and Drawer Locks Cam Locks Cam locks are the most versatile option when it comes to cabinet and drawer locks.

However, they tend to be a bit sturdier and can provide an uptick in security. Plunger Locks Plunger locks are yet another option for cabinet and drawer locks. If a drawer is inadvertently or otherwise left open during locking, it is thus necessary for a proper key to be used to unlock the chest, close the drawer, and re-lock the chest. A drawer lock for use with a lockable drawer chest includes a striker attached to a rear portion of a drawer that is selectively retained by a catch on a vertical lock bar.

The lock bar is moved between a locked and unlocked position with an actuator that acts in response Drawer Slide Locking Mechanism Pdf to motion of a chest locking mechanism. The catch includes a camming surface that urges the lock bar from the unlocked position when the striker plate impacts the camming surface as the drawer is closed. The actuator includes a relief that allows the lock bar to be moved by the striker from the locked position to the unlocked position.

In this manner, a drawer that was open at the time the chest was locked can be closed and secured without the necessity of unlocking the chest. Further features and advantages of the invention will become apparent from the following detailed description made with reference to the accompanying drawings. In the accompanying drawings, which are incorporated in and constitute a part of this specification, embodiments of the invention are illustrated, which, together with the description of the invention serve to illustrate the principles of this invention.

The drawings and detailed description are not intended to and do not limit the scope of the invention or any subsequent claims in any way. Instead, the drawings and description only describe embodiments of the invention and other embodiments of the invention not described are encompassed by this disclosure of the invention.

The Detailed Description of the Invention merely describes preferred embodiments of the invention and is not intended to limit the scope of the specification or claims in any way. Indeed, the invention as described by the claims is broader than and unlimited by the preferred embodiments, and the terms in the claims have their full ordinary meaning.

A tool chest is illustrated for exemplary purposes only. It should be apparent to one with ordinary skill in the art that the invention can be practiced with any suitable storage container having one or more drawers, such as for example, a tool chest, a tool cabinet, or a filing cabinet. The chest 10 includes a top wall 22 , side walls 24 , bottom wall 26 , and a rear wall 28 shown in FIG.

The walls define a cavity in which drawers 38 are slideably mounted. The chest is lockable, such that the drawers can be locked in the closed position. In the embodiment shown in FIGS. Other locking mechanisms are also known and can be used in practice of the present invention. Alternative locking mechanisms include, but are not limited to, combination locks or motorized lock actuators that can be controlled by wireless remote control signals.

The drawer lock mechanism 20 includes a lock bar 62 and an actuator 52 located in the chest and a striker plate 72 connected to each locking drawer. As will be described in more detail below, the lock bar 62 is moved between a locked position and an unlocked position by the actuator when the key cylinder 32 is rotated.

When the lock bar is moved downward to the locked position, a catch 67 on the lock bar is aligned with the striker plate 72 to hold the drawer in the closed position.

When the lock bar is moved upward to the unlocked position, the catch is not aligned with the striker plate and the drawer can be opened. If the lock bar is in the locked position while a drawer is open, the striker plate 72 lifts the catch 67 when the drawer impacts the catch so that the drawer may be closed and locked without the use of the key cylinder to unlock the chest.

The lock bar 62 is made of a formed metal strip 64 and includes a lock bar guide pin 63 that protrudes orthogonally from the top of the lock bar 62 and is retained in a slot 56 in the actuator A plurality of catches 67 are formed in the metal strip Each catch 67 includes a generally L-shaped finger with a first leg 67 a and an orthogonal second leg 67 b.

The second leg 67 b has a taper 67 c on a front face that confronts the striker plate when the drawer is closed. The lock bar 62 is slideably retained in a lock bar channel 94 FIG. The lock bar channel is formed from a pair of spaced rolled flanges that loosely enclose the side edges of the metal strip In some embodiments, the edges of the metal strip 64 include one or more notches Friction reducing inserts 81 FIG.

The friction reducing inserts are thicker than the metal strip 64 and therefore the lock bar rides on the friction reducing inserts 81 as it is moved within the lock bar channel The friction reducing inserts may be made from nylon or other suitable material.

The striker plate 72 is stamped from metal and has a general T-shape. The striker plate 72 is connected at one end to the drawer with punched out lances A pair of bent legs 77 engage the drawer to properly position the striker plate with respect to the drawer.

The striker plate includes a lock opening 74 at a leading end. The leading end includes a declined edge 75 that is angled to co-act with the taper 67 c on the catch 67 to lift the catch when the drawer is closed against the catch.

The actuator 52 is molded from a suitable plastic material and includes a vertically oriented plate portion 55 into which the slot 56 is cut and a perpendicular mounting plate portion 51 that fits into an actuator channel formed by a series of actuator channel tabs 23 FIGS. The Drawer Lock Mechanism Github mounting plate includes a notch 50 that provides clearance for installation of the mounting plate portion 51 between the channel tabs 23 into the actuator channel.

A link 49 is pressed into a receiving hole 54 at one end of the plate portion The actuator 52 converts linear motion of the link 49 to vertical motion of the lock bar guide pin To achieve this motion conversion, the actuator includes the slot 56 which includes a top horizontal slot portion Drawer Slide Locking Mechanism Online 57 and a bottom horizontal slot portion 59 connected by a slanted camming slot portion 58 that transitions between the top and bottom horizontal slot portion. The top horizontal slot portion 57 positions the guide pin in an up position to place the lock bar in the unlocked position.

The bottom horizontal slot portion 59 positions the guide pin in a down position to place the lock bar in the locked position. A vertical relief slot portion 53 intersects the bottom horizontal slot portion to provide a path for the guide pin to travel when the lock bar is lifted by striker plate 72 impacting a catch 67 when a drawer is closed in an already locked chest.

Referring now to FIG. The linkage includes a short link 42 that is rigidly connected to a key cylinder rod 37 such that rotation of the key cylinder is transmitted via the rod to the short link. As can be seen best in FIGS. A spring 96 urges the short link 43 into proper alignment with the bracket 46 and actuator The link 49 is pressed into a distal end of the short link and is retained by a washer 45 that allows the link 49 to rotate within the short link In this manner, the linkage 42 allows the link 49 to move the actuator side to side in response to rotation of the key cylinder Movement of the key cylinder to lock the chest causes corresponding movement of the actuator 52 to the right and the guide pin 63 slides down the slanted camming slot portion 58 and into the lower horizontal slot portion 59 to rest in the position shown in FIG.
