Anti-slip for Roller Office Chairs

Anti-slip for roller office chairs can be achieved by replacing specific wheels, using gravity wheels, or installing fixed foot pads, among other methods. Here are the specific approaches:

Replacing wheels with locking functions
There are wheels with a brake locking function available on the market, with a diameter of 60 millimeters. Their design principle is to achieve locking and unlocking through mechanical structures. When it is necessary to fix the position of the chair, push down the locking device on the wheel (usually a foldable catch or tab). At this time, the braking mechanism inside the wheel will closely fit with the wheel axle, preventing the wheel from rotating through friction and making the chair almost immovable. When it is necessary to move the chair, lift the locking device upwards, and the braking mechanism will separate from the wheel axle, allowing the wheel to roll normally. These wheels are suitable for scenarios where the chair needs to be frequently fixed and moved, such as conference rooms and offices.

Using gravity wheels
Gravity wheels are devices that use the principle of gravity to increase the resistance of the wheels. When a person sits on the chair, gravity acts on the internal mechanism of the wheel, increasing the resistance to left and right rotation of the wheel. This resistance does not completely prevent the wheel from rotating but makes movement more strenuous, thereby preventing the chair from sliding due to slight external forces to a certain extent. At the same time, due to the increased resistance, the noise generated when the wheel rubs against the ground is also reduced, making it suitable for office environments with noise requirements. The anti-slip effect of gravity wheels is related to the user's weight. The heavier the user, the more obvious the gravitational effect on the wheel, and the better the anti-slip effect.

Installing fixed foot pads
Fixed foot pads are anti-slip devices directly installed at the bottom of the chair, usually made of anti-slip materials such as rubber or silicone. Their working principle is to prevent the chair from sliding by increasing the friction between the chair and the ground. When installing, fix the foot pads under the four legs of the chair, changing the part of the chair in contact with the ground from the wheels to the foot pads. Since the foot pad material is soft and the surface is rough, it can better fit the ground, effectively preventing the chair from sliding. This method is suitable for the elderly or children, as they may not be able to flexibly operate wheels with locking functions or gravity wheels, and fixed foot pads can provide more stable support.
