摘要： Multipanel rollstops mountable on the outboard end of a wheelchair lift platform in which at least one upper panel of the rollstop folds down or telescopes to reduce the rollstop profile for stowage. Preferred embodiments include bifold, trifold or telescoping rollstops for underfloor or under vehicle lifts. In the extended multipanel position, rollstops of the invention provide increased rollstop height and occupant security in the intermediate and transfer positions of the lift as compared to non-folding or telescoping rollstops of the same stowage profile. The folding of telescoping of the rollstop is automatic upon lift stowage. In a preferred embodiment, the rollstop upper panel is folded or unfolded by a direction-reversing mechanical actuator through a contact arm which engages structure of the lift or stowage compartment, and operates automatically without requiring operator intervention. In the unfolded, deployed safety barrier configuration the top edge of the rollstops of the invention extend at least 7″ above the platform, which is the critical minimum to stop a runaway wheelchair event.

摘要翻译： 多功能滚轮可安装在轮椅升降平台的外侧，其中至少一个上滚板的上面板折叠下来或伸缩，以减少用于装载的侧倾轮廓。 优选实施例包括用于地板下或车下升降机的双叉，三重或伸缩式滚降机。 在扩展的多用途位置中，与相同的存放轮廓的非折叠或伸缩式滚动挡块相比，本发明的滚动拦截提供了提升机的中间和转移位置中的增加的停转高度和乘员安全性。 升降机装载时，自动将折臂伸缩。 在优选实施例中，通过接触臂将方向反转的机械致动器折叠或展开，所述接触臂接合提升或装载隔间的结构，并且自动地操作而不需要操作员干预。 在展开的部署的安全屏障配置中，本发明的滚动挡板的顶部边缘在平台上方至少延伸7“，这是停止轮椅事件的关键最小值。

摘要： A wheelchair lift having a foldable platform including a first platform portion foldably coupled to a second platform portion, a lifting frame, at least one lifting arm with one end pivotally coupled to the lifting frame and the other end connected to the second platform portion and adapted to pivot the lifting arm between a substantially vertical stowed position and a substantially horizontal deployed position. A post extends from the lifting arm and a locking assembly is pivotably coupled to the lifting frame. The locking assembly includes a lever arm pivotably coupled to the lifting frame, a gas spring extending between the lever arm and the lifting frame which operates to resist pivoting of the lever arm, and a mechanical spring extending between the lever arm and the lifting frame which exerts a biasing force operating to pivot the lever arm to engage the post. Pivoting the lifting arm to the deployed position actuates unfolding the platform, while pivoting the lifting arm to the stowed position actuates folding the platform and engages the post with the lever arm.

摘要： An under floor lift comprising a horizontal, U-shaped header framework which is mountable between a vehicle axle and floor, and which reciprocatingly receives a nestable carriage comprising a second U-shaped framework. The carriage comprises a transverse motor mount plate and a pair of spaced, horizontal arms between which is received the lift platform. The platform is pivotably suspended, lifted and lowered by spaced pairs of parallelogram linkages pivotably secured at their outboard ends to the outboard end of the carriage side rails and at their inboard ends to the inboard end of the lift platform. The carriage is telescoped by a gear and chain mechanism from an inboard stowed position horizontally out to a transfer level deployed position. The wheelchair lift is moved by a hydraulic/chain drive downwardly and upwardly supported by the parallelogram arms to or from a ground level position, to permit the lift to be an in-swing, negative type lift. An automatically transitioning inboard bridge plate is pivoted to the platform, and during decent inclines and forms an inboard barrier. The bridge plate is slidably mounted on channels or rails which are in turn mounted on a support plate pivotably mounted to the outboard edge of the carriage motor mount plate. The combination of the bridge and support plate assembly provides excellent stability to the lift mechanism, essentially eliminating lateral sway way and the problems attendant thereto.
