drawer-locking-mechanism The project is a locking mechanism for a secret drawer and I want it to work something like this: 1. Place an RFID tag on top of the furniture over the reader on the underside. 2. Press an N.O. button/switch inside an existing drawer. 3. When the button is pressed power will be supplied to the Arduino board. 4. The Arduino will check to see if an authorized RFID tag is in place. 5. If there is then the Arduino will activate a solenoid that will pull back and release the drawer.

The invention relates to mechanisms to prevent opening at one time more than one drawer of a vertical stack thereof. Cabinets often employ interlocking mechanisms allowing only one drawer to be opened at a time. For example, Lockibg. Opening of one drawer causes the drawer locking mechanism to be vertically displaced into a locking position by action of a member against an inclined surface.

When the drawer is closed, a second inclined surface causes the bar to be returned mecanism its original position. In both of these patents, socket and lug or ball mechanisms are used to maintain the rods in a raised position against gravity. It has been drawer locking mechanism that a simple, drawer locking mechanism interlocking device results from providing one locking bar for drawer locking mechanism drawer, using gravity to lower a bar into an interfering position, and using an inclined surface to raise the bar back drawer locking mechanism a noninterfering position drawer locking mechanism the Drawer Slide Locking Mechanism 20 drawer is shut.

Such a device avoids reliance on, and the friction of, socket and lug or ball mechanisms used to keep locking bars raised. In preferred embodiments, the inclined surfaces are on members attached to the drawers, and they pass through holes on the locking bars when the drawers are opened and shut; and interference is provided by notched members attached to the drawers and passing through holes in the locking bars.

Preferred Embodiment. The drawing, structure, and operation of a preferred embodiment will now be described. The drawing is an isometric view of a mechanism according to the invention shown attached to drawers in a cabinet. There is shown in the drawing a mechanism preventing the opening of more than one drawer of an electrical equipment cabinet at one time.

Guides 10, 12 are mounted on the frame of the cabinet drawer locking mechanism shownand each have three rectangular holes through their horizontal drawer locking mechanism in which angle-iron locking bars 14, 16, 18 are slidably mounted for limited vertical displacement.

Each bar 14, mexhanism, 18 has three rectangular holes 20, 22, 24 associated with drawers 26, drqwer, 30, respectively. Each drawer 26, 28, 30 has a bar-raising member 32, 34, or 36 with upward facing inclined surfaces 38, 40, or 42, respectively, which surfaces pass through the holes in the associated locking bar as the drawers are closed and opened.

Each drawer 26, 28, 30 also kocking a pair of locking members 44 attached to it mcehanism pass through the holes in the locking bars not associated with the raising members 32, 34, drawer locking mechanism Each of these locking members 44 has a vertical surface 46, which is located slightly behind drawer locking mechanism plane passing through the rear surface 48 of its locking bar when its associated drawer is fully closed.

When all of the drawers are closed, all of the locking bars will drawer locking mechanism in raised positions, because the upper horizontal surfaces of raising members 32, 34, 36 will be acting against the upper horizontal drawer locking mechanism surfaces of holes 20, 22, 24 in the associated locking bars. When a drawer is opened, for example, drawer 26, the inclined surface 38 passes through hole 20 in locking bar 14, thereby allowing locking bar 14 to lower by gravity so that portions lovking its rear surface 48 are moved into interfering positions with mecnanism 46 of the locking members 44 associated with drawers 28, Thus, when bar 14 is in this lower position, drawers 28, 30 cannot be opened.

As drawer 26 is closed, inclined surface 38 will contact the upper horizontal surface of hole 20 of locking bar 14, mechanizm cause locking bar 14 to be raised into a non-locking position.

Drawers 28, drader and their associated raising members 34, 36 and guide bars 18, 16, respectively, function in the same manner. All drawer locking mechanism reserved. Login Sign up.
