Latest Patents

Donald L Cool's latest patents showcase his innovative approach to chair design. One notable invention is the “Tilt mechanism, particularly for knee-tilt chair.” This novel mechanism connects the seat and pedestal of the chair through a knee-tilt system. It features a first support attached to the underside of the seat and a second support fixed to the pedestal. The invention includes a unique restoring mechanism, employing an elastomeric spring that provides a torque which increases as the seat tilts. This design facilitates a smooth transition back to a horizontal position and allows for enhanced tilting beyond an intermediate stage.

Another significant patent is the “Split nut mechanical height adjusting mechanism for a chair.” This mechanism has a load-released design that allows users to adjust the chair's height efficiently. It features a split nut engaged with the pedestal, and a wedge system that secures the nut when the chair is occupied. This ingenious invention ensures that the chair seat can be rotated freely without adjusting the height, simplifying user interaction and enhancing overall usability.
