Door Hinges

Description
Description

A door hinge is a mechanical bearing that connects a door to a frame, allowing it to rotate along a horizontal axis. The hinge is typically made of metal and consists of two plates, one mounted on the door and the other on the frame, that are connected by a pin, also known as a hinge pin, which allows the door to rotate. The hinge plates typically have knuckle, leaf and pin, which form the hinge mechanism. The hinge is designed to provide a pivot point for the door to rotate around and also to support the weight of the door. There are different types of hinges, each with its own unique design and application such as butt hinges, continuous hinges, spring hinges, pivot hinges, and more.

History
History

The history of door hinges dates back to ancient times, where simple wooden hinges were used in Egypt and Greece. In the Middle Ages, iron hinges were introduced in Europe, providing greater security than wooden ones. The Industrial Revolution brought mass production of door hinges, making them more affordable. During the 19th century, brass, bronze, and steel hinges were developed and became popular. Today, door hinges come in a wide range of materials and finishes, with different designs and mechanisms to suit different types of doors and usage.

Future

Door hinges, often overlooked, are evolving to suit modern needs. Soft-close hinges, which prevent doors from slamming shut, are becoming a household favorite. Additionally, concealed hinges, offering a cleaner look by hiding the hinge plate, are on the rise. Some even come with advanced materials to resist corrosion or wear. As homes prioritize both function and design, hinges will adapt, ensuring doors swing smoothly while also complementing the aesthetics of contemporary spaces.

Common Questions
Common Questions
What causes door hinges to sag?

Door hinges can sag due to a variety of reasons, including improper installation, a lack of maintenance, or wear and tear. The most common cause of sagging hinges is a loose or worn hinge pin, which can cause the door to lose its proper alignment and sag. Additionally, the door or door frame may have warped or twisted over time, or if the door is too heavy for the hinges, it will cause them to sag over time as well.

What type of door hinge is the strongest?

Continuous hinges, also known as piano hinges, are considered to be the strongest type of door hinge. They are made of one long piece of metal and are mounted continuously along the length of the door, providing more support and stability than traditional hinges. They are typically used in heavy-duty applications such as industrial and commercial doors, and are known for their durability and strength.

Why are door hinges mounted on the interior of the door?

Door hinges are typically mounted on the interior of the door for security reasons. When the hinges are on the inside, it makes it much harder for someone to remove the door from the outside, as the hinges are not visible and cannot be tampered with. This makes it harder for intruders to break in, and provides an extra layer of security for the building. Additionally, mounting the hinges on the inside can also help protect the hinges from the elements and prolong their lifespan.

Hirline Door Hinge
Style and size comparison drawing of the Hirline Door Hinge compared to other door hinges

A Hirline Door Hinge, or concealed hinge, is a type of hinge that is designed to be hidden when the door is closed. It consists of two parts, a mounting plate that is attached to the cabinet or frame, and a hinge arm that is attached to the door. The unique design of a hidden hinge is that it is concealed inside the cabinet or frame when the door is closed, and it is not visible from the outside.

Hirline Hinges are commonly used in kitchen cabinetry and furniture, where a sleek and clean look is desired. They are also used in situations where the hinge needs to be hidden, such as in pocket doors or in sliding doors. They are typically made of steel or another strong metal, and the pin is usually made of steel or brass.

The Hirline Door Hinge has a leaf height of 3.94” (100 mm), open width of 2.72” (69 mm), and depth of .47” (12 mm). The overall pin height is 4.13” (105 mm) and the closed width is 1.85” (47 mm).

Butt Door Hinge - Round
Style and size comparison drawing of the Butt Door Hinge (Round) compared to other door hinges

The Butt Door Hinge is a hinge consisting of two plates, one attached to the door and the other attached to the frame. These plates are connected by a pin, which allows the door to rotate around it. The hinge plates have knuckles that form the pivot point when the hinge is in use. The hinge is designed to mount on the surface of the door and frame. Because of its simple design, it has a low failure rate, making it a reliable and long-lasting hinge. However, it has a limited range of motion and is not suitable for doors that need to open at a wide angle or in both directions. They are commonly used for interior and exterior doors in residential and commercial settings.

The Butt Door Hinge (Round) has a leaf height of 3.46” (88 mm), open width of 3.46” (88 mm), and depth of .47” (12 mm). The overall pin height is 3.62” (92 mm) and the closed width is 1.97” (50 mm).
