Office Chair Wheel Fixation
There are several main methods for fixing the wheels of an office chair:
Using Fixed Fittings Fixed corner fittings are specially designed devices that can be inserted into the connection part of the chair's wheels to directly restrict the rotation of the wheels. After installation, the chair will be completely fixed, suitable for scenarios that require long-term stillness, such as conference rooms or fixed workstations. Its advantages lie in its simple structure and convenient operation, but it has low flexibility and requires manual disassembly to restore mobility.
Brake Pad Wheels These wheels have built-in brake devices. The locking mechanism is triggered by stepping on or pressing the brake pads on the surface of the wheels. Once braked, the friction between the wheels and the ground is significantly increased, effectively preventing sliding. This design is commonly found in medical equipment or industrial chairs, balancing daily mobility and emergency fixation needs. However, the wear of the brake pads needs to be regularly checked to ensure safety.
Seat-Brake Wheels Seat-brake wheels use gravity sensing principles. When the user sits down, the body weight pressure triggers the internal locking structure, automatically fixing the wheels; when getting up, the lock is released, and mobility is restored. This design requires no additional operation and is suitable for office scenarios that require frequent switching between static and dynamic states. However, attention should be paid to the weight-bearing range, as overloading may cause the lock to fail.
Chair Caster Fixers There are various materials of fixers available on the market. For example, PVC soft-bottom fixers increase friction through flexible materials, while nylon felt fixers use fiber surfaces to reduce sliding. During installation, simply insert the fixer between the wheels and the ground without disassembling the original wheels. It is easy to operate and can be reused. Such products are especially suitable for protecting wooden floors or tile floors from scratches.
Snap-Spring Insertion Foot Pads These foot pads are tightly connected to the wheel axle through a snap-spring structure, with anti-slip materials (such as rubber or felt) at the bottom to enhance stability. During installation, the original wheels need to be replaced with matching foot pads, suitable for scenarios that require complete fixation and infrequent movement. Some products also have adjustable height functions to adapt to different floor flatness.
Braked Casters Some manufacturers offer braked casters that can be locked using a side brake lever or a foot pedal switch. These casters retain the flexibility of 360-degree rotation while allowing for quick fixation when needed. They are commonly found in high-end office chairs or adjustable workstations. When purchasing, attention should be paid to the compatibility of the wheel diameter with the chair and the durability of the brake mechanism.
Rubber Slot Fixers These fixers are made of elastic rubber materials and wrap around the bottom of the wheels through a slot structure, using the friction generated by material deformation to restrict movement. During installation, simply slip the fixer over the wheels without the need for tools, suitable for temporary fixation needs. However, long-term use may cause rubber aging, and regular replacement is required to maintain effectiveness.
Caster Chair Foot Covers TPU silent foot covers wrap around the wheels with highly elastic materials and have anti-slip patterns at the bottom; felt-bottom fixers use fiber surfaces to reduce sliding. These products combine fixation and floor protection functions, are easy to install, and have low costs. However, appropriate models need to be selected according to the wheel size to avoid looseness or detachment.
