摘要： An automatic push button wheelchair securement device for mounting on the floor of a wheelchair transporting vehicle.As the wheelchair occupant rolls the wheelchair to the designated location on the securement device; by pressing a push button the holding flaps of the securement device will rise by means of two air cylinders to contact the rear large wheels tangentially, hence, providing securement for the chair and preventing it from rolling forward or backward in case of sudden stops or collision of the vehicle.The holding flaps, in another embodiment may be comprised of four individual holding flaps self adjusted and positioned by means of electrical linear actuator and infrared sensing device.

摘要： A wheelchair lift with hydraulic power unit and automated folding platform for installation on the floor, inside the opening defining walls of a vehicle to provide for loading and unloading of wheelchair occupants to and from the vehicle. Completely automated, retractable, collapsable folding platform. Hydraulic power unit (10) of the lift and the hydraulic cylinder (28) are totally enclosed, and contained in the power box. The power unit provides power for upward motion of the platform and gravity descent for downward motion of the platform. The platform is pivotally retracted and held in a vertical position in half of the opening space of the vehicle door. The folding motion is accomplished by a folding arm driven against a cam roller which starts the motion of the ball joint linkages inside the platform tubing structure. This initiates a resulting revolving motion of one half section of the platform which folds the platform in a smooth un-interrupted continuous manner.
摘要翻译：具有液压动力单元和自动折叠平台的轮椅升降机，用于安装在地板上，位于车辆开口的开口内部，以提供轮椅乘客往返车辆的装载和卸载。完全自动化，可伸缩，折叠折叠平台。电动液压动力单元（10）和液压缸（28）完全封闭，装在动力箱内。动力单元为平台的向上运动提供动力，并为平台向下运动提供重力下降。平台枢转地缩回并保持在车门的开口空间的一半的垂直位置。折叠运动通过抵靠凸轮辊驱动的折叠臂来实现，该凸轮辊开始平台管道结构内的球形接头连杆的运动。这引发了平台的一半部分产生的旋转运动，其以平滑的不间断的连续方式折叠平台。

The folding motion is accomplished by a folding arm driven against a cam roller which starts the motion of the ball joint linkages inside the platform tubing structure. The automatic folding action of the platform segments is also accomplished by other actuating devices such as hydraulic cylinder or a linear actuator (118) attached to a folding mechanism (114) and (116) for a complete 180 degree rotation and overlay of one segment of the platform over another.
