摘要： A method of turning typical doorknobs and other knobs without having to grasp the knob enables persons with hand debilities to open doors. The method involves installation of a knob cover which is round and made of a resilient material which can be slipped over the knob without tools, and will snugly remain around the knob. Multiple levers protrude from the knob cover, so that pushing any of the levers will cause the knob to be turned. Each lever is substantially U-shaped with a rounded apex, to avoid discomfort which might be caused by pointed levers. Furthermore, each lever is made of a resilient, soft material to facilitate movement of the levers by sensitive hands. Each lever extends from the cover a sufficient distance to allow a closed fist to engage and push the lever, while each lever is short enough to avoid contact with a door jam or adjacent wall when the knob cover is installed on a doorknob.

摘要翻译： 典型的门把手和其他旋钮的旋转方法，而不必掌握旋钮，使具有手部难度的人打开门。 该方法包括安装圆形的旋钮盖，弹性材料可以在没有工具的情况下滑过旋钮，并且将紧贴地保持在旋钮周围。 多个杠杆从旋钮盖突出，以便推动任何一个杆将导致旋钮旋转。 每个杠杆基本上为U形，具有圆形顶点，以避免可能由尖杆引起的不适。 此外，每个杠杆由弹性柔软的材料制成，以便利用敏感的手来操纵杠杆。 每个杠杆从盖子延伸足够的距离，以允许闭合的拳头接合和推动杆，同时当杠杆盖安装在门把手上时，每个杆足够短以避免与门卡住或相邻的壁接触。
