摘要： An improved dual hydraulic, parallelogram arm wheel chair lift assembly for use in commercial vehicles, such as vans or buses. The lift assembly includes a platform connected at one end to a pair of parallelogram linkages, each of which is provided with a power-up, gravity-down hydraulic cylinder for pulling the parallelogram linkages and platform from a lowered loading position to an immediate transfer position, and thence to a folded, generally upright stored position. The pulling action of the hydraulic cylinders with hydraulic fluid working on the rod side reduces side loading on the piston head and wear on pivot pins of the parallelogram linkages. The hydraulic cylinders are self-bleeding of air during gravity down operation to reduce spongy and jerky operation. The lift assembly has an improved base member employing an additional base support plate to form a box structure to increase strength and reduce moment-induced bending of the mounting plate. Tie downs are also provided to the side supports to assist in reducing sway movement of the side supports. An improved, highly precise microswitch trigger assembly mounted independent of arm pivot pins and large bearing surface fixed arm pivot pins are disclosed. The hydraulic cylinders are mounted base down and act at right angles to the conventional mounting scheme, with full extension at lower load position and fully closed (retracted) at the upper stowed position.
摘要翻译：一种改进的双液压，平行四边形臂轮椅升降机组件，用于商业车辆，如货车或公共汽车。提升组件包括一端连接到一对平行四边形连杆的平台，每一个平行四边形连杆都设置有上下推重的液压缸，用于将平行四边形连杆和平台从降低的装载位置拉到直接传递位置，然后到折叠的，大致直立的储存位置。液压缸的拉动动作使液压油在杆侧工作，减少活塞头上的侧向负荷，并磨损平行四边形连杆的枢轴销上。液压缸在重力下降运行时是自我渗出的空气，以减少海绵和干燥的运行。提升组件具有改进的基座构件，其采用额外的基部支撑板以形成箱结构，以增加强度并减小安装板的力矩引起的弯曲。绑带也设置在侧支架上，以帮助减少侧支架的摆动运动。公开了一种改进的，高度精确的微动开关触发器组件，其独立于臂枢轴销和大的轴承表面固定臂枢轴销安装。液压缸底座安装在底部，与传统的安装方案成直角运动，在较低的载荷位置完全伸展，并在上部收起位置完全关闭（缩回）。

摘要： Passive rotary wheelchair lift that is retrofittable in transit vehicles on either the forward or rearward edge of a side double-door step well. The lift employs in its preferred embodiment a double slide tube having a box frame with a cross header. A hydraulic cylinder actuates a pair of chains, one descending down each lift tube to operate the vertical lift. A manual hand pump is provided in the case of power failure. Secured to the bottom of inner telescoping lift tubes is a plate carrying a power actuator for rotating the lift platform from a deployed horizontal position to a vertical stowed position. In the stowed position the platform is approximately 26 inches in length and 36 inches in width. The platform has one or more slide-mounted extension sections which permit the platform to extend out to a full 51 inches. Manual or power-actuated wheel stops are provided at the rear entry and the forward end, for either one way or two way entry/exit onto the platform. Lockout circuitry prevents the actuators from rotating or stowing if the platform is not in its full raised position. Actuator clutch mechanism prevents the platform from being stowed if it is occupied. As installed, one of the double doors is openable permitting the stairwell to be used by an able-bodied person. The stowed platform is nested against a transit seat and remains behind the closed door half of the double-door pair. For use by a wheel chair user, both doors are opened and the lift is deployed, rotated and actuated to raise or lower the user to the ground, platform or curb. A special power actuating and ground contact locking plate is employed to permit the entry the entry wheelstop to be both power actuated and pivoted to the stowed position. The actuators can be disconnected for full manual operation in the event of power failure. A variety of lockout switches and circuitry is shown.

摘要： A hydraulic drive system for an access apparatus and a method of access is presented. The hydraulic drive system may include a hydraulic power unit, a hydraulic cylinder and a subsystem for limiting motion of the access system according to the position of and/or load supported by the access system. The subsystem may prevent motion, such as stowing and/or folding, when the access apparatus is supporting a load and/or is in a predetermined position. To limit motion, the subsystem may create a fluid path from the hydraulic power unit that bypasses the hydraulic cylinder, thus preventing the cylinder from moving the access apparatus. The subsystem may include a first valve that is opened when the access apparatus is in the predetermined position, and/or a second valve that is opened when the access apparatus is supporting a load.

摘要： A vehicle wheelchair access system with a platform which includes a right-side vertical arm and a left-side vertical arm, both having elongated supports with a first and second portion. The first portions of the elongated supports are pivotably coupled with the vertical arms, which operate to deploy the platform structure. A moveable platform section is coupled intermediate to the right-side and left-side elongated supports for movement between the first and second portions of the right-side and left-side elongated supports. A linkage connects the moveable platform section for movement with the actuator between a stowed and a deployed orientation.

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.

摘要： An electromagnetic contactor comprising a terminal and contact block supported at one end on a magnetic frame includes cooperating interlocking means on its coil bobbin and the block for rigidly supporting the block at an additional location. The interlocking means on the coil bobbin include a pair of oppositely directed support arms with upstanding projections in mating engagement with wall members of the block. Each support arm also has a recess that receives a sheet metal coil terminal with lugs that are bent into contact with the arm after insertion of the terminal into the recess to prevent movement of the coil terminal with respect to the arm.
