Detailed introduction to the types of doors and windows hinges
Introduction: There are numerous accessories for doors and windows, and among them, hinges are a crucial component. Let’s delve deeper into this topic together today.
Hinges, commonly referred to as pivot joints, are typically designed in a two-fold manner. These are metal pieces that connect two parts of furniture and allow movement. Essentially, hinges are devices that connect or rotate, enabling doors, covers, or other swinging components to pivot. They are generally made of a pair of metal plates joined by a pin.
1. What are the types of hinges?
Hinge Types:
Ordinary Hinge: Often used for cabinet doors, windows, and doors. Made from materials like iron, copper, and stainless steel. The downside of ordinary hinges is that they lack the spring functionality. Once installed, various stoppers must be added to prevent the door from being blown open by the wind.
Pipe Hinge: Also known as a spring hinge. Primarily used for connecting furniture door panels, it typically requires a panel thickness of 16 to 20 mm. Materials include galvanized iron and zinc alloy. Spring hinges come with adjustment screws, allowing you to fine-tune the height and thickness of the panels. One of its standout features is the ability to adjust the opening angle of the cabinet door based on available space. Beyond the standard 90-degree angle, there are options for 127 degrees, 144 degrees, 165 degrees, and so on, ensuring compatibility with various cabinet designs.
Door Hinge: Divided into regular and bearing types. The bearing type can further be categorized by material into copper and stainless steel. Currently, copper bearing hinges are more popular due to their attractive appearance, durability, reasonable pricing, and inclusion of screws.
Bearing Hinges (Copper): Each hinge contains a one-way thrust ball bearing in the shaft, making the door opening and closing smooth and effortless. These are often used on heavy-duty doors or specialized steel-framed steel doors. Inclined Surface Removal Hinge: Utilizes the beveled surface of the hinge and the weight of the door leaf to automatically close the door. It's ideal for lighter wooden doors or half-section doors like those found in toilets.
Cold Storage Door Hinge: Coated with surface paint, large-sized hinges are made of steel plate while smaller sizes are crafted from cast iron. They're used on cold storage doors or insulated doors requiring extra durability.
Fan Hinge: The stacking thickness of the two sheets in a fan-shaped hinge is approximately half that of a standard hinge, making it suitable for various doors and windows that require rotation and opening/closing functions.
Silent Hinge: Also known as nylon washer hinges, these produce minimal noise when opening and closing doors and windows. They are primarily used in public buildings.
Single Flag Hinge: Made of stainless steel, these hinges are rust-resistant, wear-resistant, and easy to disassemble. They are commonly used on double-layer windows.
Flip Window Hinge: During installation, the two pages with spindles are mounted on both sides of the window frame, while the two pages without spindles are installed on both sides of the window sash. One of the slotless spindle plates must be installed on the side of the slotted sash for loading and unloading of the window sash. These are used on movable windows in factories, warehouses, residential buildings, and public buildings.
Multi-function Hinge: When the opening angle is less than 75 degrees, it has an automatic shut-off function. Between 75 and 90 degrees, it remains stable, and above 95 degrees, it automatically locks in place. This hinge can replace a regular hinge on a door.
Anti-theft Hinge: Unlike ordinary hinges, which can be easily removed by pulling out the pin, anti-theft hinges prevent the door leaf from being removed thanks to the self-locking mechanism of the pins and pinholes on both hinge plates. They are suitable for residential doors.
Spring Hinge: Automatically closes the door leaf after opening. Single-spring hinges can only be opened in one direction, while double-spring hinges can be opened in both directions. They are commonly used on public building gates.
Double-axis Hinge: There are two types, allowing the door leaf to be opened, closed, and removed freely. 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. Hinges play a vital role in furniture hardware accessories, and the quality of the hinges directly affects the usability of furniture and doors.
Based on the base type, they can be classified into removable and fixed types. Depending on the arm body type, they can be categorized as slide-in and card types. Based on the door panel cover position, they are divided into full cover (straight bend, straight arm), covering 18 cm; half cover (middle bend, curved arm), covering 9 cm; and inner (big bend, big bend) where the door panels are hidden inside.
From the styles of the hinge development stage, they are divided into: one-stage force hinge, two-stage force hinge, hydraulic cushion hinge, touch self-opening hinge, etc. According to the door opening angle, hinges generally range from 95-110 degrees, with special ones ranging from 25, 30, 45, 135, 165, to 180 degrees. Based on the hinge type, they include 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 can be used for cabinet doors, windows, and doors. In terms of material, they can be iron, copper, or stainless steel. The downside of ordinary hinges is the absence of spring functionality. After installation, stoppers must be added to prevent the wind from blowing the door panel. There are also special hinges like stripping hinges, flag hinges, and H hinges, which can be disassembled and installed according to various specific needs.
2. Spring Hinges: Mainly used for cabinet doors and wardrobe doors. They generally require a board thickness of 18-20 mm. From the material perspective, they can be divided into galvanized iron and zinc alloy. From a performance standpoint, they can be categorized as hole-free and hole-required. Hole-free hinges, known as bridge hinges, resemble bridges and are not restricted by door styles. Hole-required hinges are commonly used on cabinet doors, featuring door panel holes, limited door styles, and preventing the door from being blown open by the wind after closure without the need for additional stoppers.
3. Door Hinges: Divided into ordinary and bearing types. The bearing type can be further divided into copper and stainless steel. Judging by current consumer trends, copper bearing hinges are more prevalent due to their appealing design, brightness, reasonable pricing, and screw inclusion.
4. Mechanical and electromechanical cabinet hinges. These include nylon hinges with high wear resistance; corrosion-resistant, stronger zinc alloy hinges; and corrosion-resistant, oxidation-resistant, and strong stainless steel hinges. They are frequently used in electromechanical cabinet doors, mechanical equipment operation boxes, and other products.
5. Heavy-duty hinges: Due to their unique installation positions, hinges require high standards. Typically, their size is above 150mm, with a high load-bearing capacity, and their shape and structure meet the special requirements of cabinet doors. They are commonly 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 and are widely used in daily life.
7. Other hinges include countertop hinges, door hinges, and glass hinges. Glass hinges are used to install frameless glass cabinet doors, requiring a glass thickness of no more than 5-6mm. They possess all the properties of spring hinges, except for magnetic suction and top-mount types, such as Pepsi, magnetic glass hinges, etc.
