Introduction: There are countless accessories available for doors and windows, and among these, hinges play a crucial role. Today, let's delve deeper into this essential component with the help of this article.
Hinges, commonly referred to as pivots, are frequently designed in a two-fold manner. They act as metal connectors that link two parts of furniture together while allowing movement. Essentially, a hinge serves as a mechanism for connecting or rotating components, enabling doors, covers, or other swing elements to pivot. Typically, a hinge consists of a pair of metal blades attached to a pin.
1. Types of Hinges:
Ordinary Hinges: These are widely used for cabinet doors, windows, and doors. Made from materials such as iron, copper, and stainless steel, the downside of ordinary hinges is the absence of a spring hinge feature. Without additional stops or beads, the door panel might swing open due to wind.
Tube Hinges: Also known as spring hinges, they are primarily used to connect furniture door panels. They generally require a panel thickness of 16 to 20 mm. Made from galvanized iron and zinc alloy, tube hinges come equipped with adjustment screws to tweak the height and thickness of the panels vertically and horizontally. One standout feature is their ability to adjust the opening angle of cabinet doors based on space constraints. Besides the standard 90-degree angle, hinges matching angles of 127 degrees, 144 degrees, and 165 degrees are available, ensuring various cabinet doors can be extended accordingly.
Door Hinges: These are categorized into ordinary and bearing types. Bearing hinges further divide into copper and stainless steel varieties. Currently, copper bearing hinges are more popular due to their attractive design, brightness, reasonable pricing, and screw attachment.
Bearing Hinges (Copper): Each hinge contains a one-way thrust ball bearing in its shaft, making the door operation smooth and effortless. They are ideal for heavy-duty doors or special steel-framed steel doors. Inclined Surface Removal Hinges: These hinges utilize the beveled surface of the hinge and the weight of the door leaf to automatically shut the door. They work best for lighter wooden doors or half-section doors like those found in toilets.
Cold Storage Door Hinges: These are surface baked and crafted from steel plate for larger sizes or cast iron for smaller ones. They are utilized on cold storage doors or heavier insulated doors.
Fan Hinges: The stacked thickness of the two sheets in fan-shaped hinges is approximately half that of regular hinges, making them suitable for various doors and windows requiring rotation and opening/closing.
Silent Hinges: Also known as nylon washer hinges, they ensure quiet operation when opening and closing doors and windows. They are primarily used in public buildings.
Single Flag Hinges: Made from stainless steel, these hinges are rust-resistant, wear-resistant, and easy to dismantle. They are commonly used on double-hung windows.
Flip Window Hinges: During installation, the two pages with spindles are placed on either side of the window frame, while the two pages without spindles are installed on either side of the window sash. One of the slots on the spindle-free sash must be installed for the loading and unloading of the window sash. These are used on factory, warehouse, residential, and public building movable windows.
Multi-function Hinges: These hinges have an automatic closing function when the opening angle is less than 75 degrees. At an angle of 75 to 90 degrees, they remain stable by themselves. When the angle exceeds 95 degrees, they automatically lock into place. This hinge can replace a regular hinge on a door.
Anti-theft Hinges: Unlike ordinary hinges where the door leaf can be removed once the shaft is pulled out, anti-theft hinges prevent this through the self-locking of the pins and pinholes on both hinge sheets, thereby preventing the removal of the door leaf and providing an anti-theft effect. They are suitable for residential doors.
Spring Hinges: These automatically close the door leaf after it’s opened. A single-spring hinge can only be opened in one direction, whereas a double-spring hinge can be opened in both directions. They are mainly used on public building gates.
Double-Axis Hinges: These allow free opening, closing, and removal of the door leaf. They are suitable for general doors and windows.
2. Introduction to Door Hinges:
A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Composed of a movable assembly or a foldable material, hinges hold a significant position in furniture hardware accessories, directly impacting the usability of furniture and doors.
Classification based on base type divides hinges into removable and fixed types. Based on the arm body type, they are classified into slide-in and card types. Depending on the door panel coverage, they are categorized into full cover (straight bend, straight arm), half cover (middle bend, curved arm), and inner (big bend, big bend) types. By the hinge development stages, they are divided into one-stage force hinges, two-stage force hinges, hydraulic cushion hinges, touch self-opening hinges, etc. Based on the door opening angle, hinges range from 95 to 110 degrees, with special ones ranging from 25 to 180 degrees. By hinge type, they are classified into ordinary first and second-stage force hinges, short-arm hinges, 26-cup mini hinges, bullet hinges, aluminum frame door hinges, special angle hinges, glass hinges, rebound hinges, American hinges, damping hinges, thick door hinges, etc.
Classified by usage occasion:
1. General Hinges: Commonly known as regular hinges, they are used for cabinet doors, windows, and doors. They are made of iron, copper, and stainless steel. The downside of regular hinges is the lack of spring hinge functionality. Beads must be installed after installation to prevent the door panel from being blown open by the wind. Special hinges like stripping hinges, flag hinges, and H hinges can be disassembled and installed based on specific needs.
2. Spring Hinges: Primarily used for cabinet and wardrobe doors, they typically require a board thickness of 18-20mm. From a material perspective, they can be divided into galvanized iron and zinc alloy. Performance-wise, they can be categorized into hole-drilled and non-hole-drilled types. Non-hole-drilled ones are called bridge hinges, which don't require drilling holes in the door panel and aren't style-restricted. Hole-drilled ones are the common spring hinges used on cabinet doors.
3. Door Hinges: Divided into ordinary and bearing types. Bearing hinges can be further divided into copper and stainless steel. Copper bearing hinges are more prevalent due to their attractive style, brightness, reasonable pricing, and screw attachment.
4. Mechanical and Electromechanical Cabinet Hinges: These include nylon hinges with high wear resistance, corrosion-resistant zinc alloy hinges, and corrosion-resistant, oxidation-resistant, and high-strength stainless steel hinges. They are commonly used in electromechanical cabinet doors and mechanical equipment operating boxes.
5. Heavy-Duty Hinges: Due to their special installation positions, these hinges have high requirements. Generally sized above 150mm, they have a large load-bearing capacity and meet the special structure of cabinet doors. They are often used in large doors like refrigerators and freezers and are mostly made of zinc alloy.
6. Specialty Hinges: These include corner hinges with a large opening angle, commonly seen in daily use.
7. Other Hinges include countertop hinges, door hinges, and glass hinges. Glass hinges are used to install frameless glass cabinet doors, with a glass thickness requirement of no more than 5-6mm. They possess all the properties of spring hinges but do not have magnetic suction or upper and lower top-mount types, such as Pepsi magnetic glass hinges, etc.
