摘要： A wiper assembly (90) for surface maintenance vehicles (20) has a non-destructive failure mode when impacting stationary objects, or otherwise becoming subject to instantaneous or rapidly increasing resistance to forward movement, due to an improved mechanical coupling. Portions (66) of each improved mechanical coupling may either become fully disconnected if the stress force reaches a threshold force value or recoils to the original mounting location after absorbing forces that are less that the threshold force value. The threshold value force is designed to avoid damage to the wiper assembly (90), the articulated mounting member (40)(if any), and the maintenance vehicle (20) itself. The improved mechanical coupling utilizes a resilient, deformable member (66) that adds a modicum of additional travel in response to stress forces imparted to a wiper assembly (90). Accordingly, the teaching of the present invention may be applied to previously manufactured surface maintenance equipment and vehicles in the form of retrofitted mechanical couplings, requiring modest engineering and re-installation efforts.
摘要翻译：由于改进的机械耦合，用于表面维护车辆（20）的刮水器组件（90）在撞击静止物体时具有非破坏性故障模式，或者由于改进的机械联接而以其他方式变得受到即时或快速增加的向前移动的阻力。如果应力在达到阈值力值之后或吸收力小于阈值力值的原始安装位置后，每个改进的机械联轴器的部分（66）可能完全断开。阈值力被设计成避免损坏刮水器组件（90），铰接安装构件（40）（如果有的话）和维护车辆（20）本身。改进的机械联接利用弹性的可变形构件（66），其响应于施加到擦拭器组件（90）的应力而增加了一定量的附加行程。因此，本发明的教导可以以改进的机械联轴器的形式应用于以前制造的表面维护设备和车辆，需要适度的工程和重新安装努力。

摘要： A releasable squeegee assembly for coupling to a surface maintenance machine and including a compliant bushing and an over-center lever attached to a pull rod and compliant spring. The compliant bushing is compressed via said over-center lever with said compliant spring providing a spring force. A bushing sleeve is provided to limit the degree of compression of said compliant bushing by the over-center lever. A method of coupling a squeegee assembly to a surface maintenance machine is also provided.
