In cabinet making, a door is designed to close automatically when it hits the drawer due to a mechanism known as a self-closing hinge. This feature is incorporated to ensure that the cabinet doors stay closed securely and neatly when not in use, preventing them from being left ajar accidentally.
Here's how it works:
Self-Closing Hinges: Cabinet doors are typically attached to the cabinet frame using hinges. Self-closing hinges are designed with a special mechanism that automatically pulls the door closed when it reaches a certain point in its swing. This mechanism can be in the form of a spring or a hydraulic device.
Magnetic Latch: In some cases, there may also be a magnetic latch mechanism involved. When the door is pushed to a closed position, a magnet inside the hinge or the cabinet frame attracts a metal plate on the door, creating a secure closure.
Drawer Positioning: The location of the drawer within the cabinet is strategically placed to activate the self-closing mechanism. As the door swings shut, it comes into contact with the front edge of the drawer. This contact triggers the self-closing hinge, causing it to pull the door closed.
Smooth Operation: The self-closing hinge ensures that the door closes gently and smoothly, preventing any slamming or abrupt movement that could cause damage to the door or the cabinet frame.
By incorporating self-closing mechanisms in cabinet doors, cabinet makers can enhance the overall functionality and aesthetics of the cabinets. It also adds convenience for users, as they don't have to worry about closing the doors manually every time they use the cabinet.
