DOOR INTERLOCK ASSEMBLY KIT

Doors are common in restaurant equipment design from refrigerators and freezers, to ovens to ice machines. A door is a hinged or otherwise movable panel that allows access to an enclosure, cabinet, bin, or other cavity or container.  A door assembly comprises the components that work in tandem to allow the door to function properly such as the door set, strike, catch and lock set. Doors may be hinged and swing open and closed, or they may slide within a frame. Very frequently, restaurant equipment doors feature tempered glass windows which allow for visual inspection or merchandising of food and beverage products.

An interlock is a feature that makes the state of two mechanisms or functions mutually dependent (working together as one). It may be used to prevent undesired states in a finite-state machine, and may consist of any electrical, electronic, or mechanical devices or systems. In most applications, an interlock is used to help prevent a machine from harming its operator or damaging itself by preventing one element from changing state due to the state of another element, and vice versa

Parts of a lock assembly include a cylinder or lock body, where a key is inserted. When locked, the cylinder engages a series of spring-loaded pins that keep the cylinder from turning. When a key is inserted, the uneven edge pushes the pins upward to fit the key’s height in that location within the lock body. Essentially, it recognizes the correct key when the pins move into their proper places. This “opens” the cylinder, allowing the bolt to move, and you to open the lock. The lock engages a piece of metal or plastic that extends from the door into the receiver and holds it closed. In addition, a lock assembly may include mounting components, brackets, washers and bolts.
