a cup hinge, a common type of hinge used for cabinet doors, along with illustrations of how to adjust it.
The Hinge:
The main part of the image shows the cup hinge itself. It consists of two main parts:
Cup: A circular part that is mortised (recessed) into the cabinet door.
Mounting Plate: A plate that is screwed onto the cabinet frame.
The hinge has several screws that allow for adjustment:
Side-to-Side Adjustment Screws: These screws (usually two) are used to adjust the horizontal position of the door, moving it left or right relative to the cabinet frame. This is often used to align the door with adjacent doors or to adjust the gap between the door and the frame.
Up-and-Down Adjustment Screw: This screw is used to adjust the vertical position of the door, moving it up or down. This is used to align the top or bottom edge of the door with the cabinet frame or other doors.
In-and-Out Adjustment Screw (Depth Adjustment): This screw adjusts the distance between the door and the cabinet frame. This is used to set the overlay (the amount the door overlaps the frame) or to correct for doors that rub against the frame.
Adjustment Illustrations:
The three smaller images below the hinge show the effects of these adjustments:
Side-to-Side Adjustment (Horizontal Arrows): The red horizontal arrows indicate the movement of the door left or right.
Up-and-Down Adjustment (Vertical Arrow): The red vertical arrow indicates the movement of the door up or down.
In-and-Out Adjustment (Depth Adjustment - Horizontal Arrow): The red horizontal arrow, pointing towards and away from the cabinet, indicates the movement of the door closer to or further from the cabinet frame.
How to Adjust:
Generally, to adjust a cup hinge:
Locate the adjustment screws on the hinge.
Use a screwdriver (usually a Phillips head) to turn the screws.
Make small adjustments and check the door alignment after each adjustment.
Continue adjusting until the door is properly aligned.
Common Adjustment Issues:
Doors that are not aligned with each other: Use the side-to-side and up-and-down adjustment screws to align the doors.
Doors that rub against the frame: Use the in-and-out adjustment screw to increase the gap between the door and the frame.
Uneven gaps between doors: Use a combination of all three adjustment screws to achieve even gaps.
This image is a helpful visual guide for understanding how cup hinges work and how to adjust them to achieve proper cabinet door alignment.
