US Patent 11864663 Quick release connector

A quick release connector for coupling a removable device with a mounting surface. The mounting surface can include a wheelchair arm, and the removable device can include a user controller. The quick release connector can enable a user to briefly contact a release mechanism, rotate the removable device by a limited amount, and remove the device with a single hand. The quick release connector can robustly couple the removable device with the mounting surface, enabling the mounted removable device to resist dislodging by knocks and bumps.
