摘要:
A lift-up mechanism (50, 150) installed inside a vehicle serves to move a seat unit (10, 110) into or out of the vehicle. The seat unit (10, 110) is used as a passenger seat inside the vehicle and as a wheelchair outside the vehicle. Connecting plates (56, 156) are disposed on the lift-up mechanism (50, 150) permit the lift-up mechanism (50, 150) to be connected to the seat unit (10, 110) by inserting the connecting plates into connecting recesses (40, 140) formed in the seat unit (10, 110). Front wheels (60, 160) and rear wheels (70, 170) of the seat unit (10, 110) can be retracted and extended. A drive unit having an electric motor or similar drive may be provided to retract and extend the front wheels (60, 160) and the rear wheels (70, 170). An attitude changing arrangement may be provided to automatically change the attitude of the front wheels (60, 160) when the front wheels (60, 160) and the rear wheels (70, 170) are retracted.
摘要:
The disabled person lifting apparatus permits an object, such as a wheelchair user, to be moved between a first position and a second position in which the first and second positions are at different vertical distances. For a vehicle wheelchair lifting apparatus, the first position may a ground level and the second position may be at the height of the door of the vehicle so that the disabled person may enter the vehicle. When the lifting apparatus is not being used, it may be stored underneath the vehicle or in the floor of the vehicle. The lifting apparatus may include a pair of lifting arms at each side of a lifting platform that are driven by an electrical motor or a hydraulic ram. The lifting apparatus may move in a vertical direction with no horizontal movement.
摘要:
A wheelchair lifting platform for transporting a wheelchair passenger into and out of the rear door of a vehicle such as a van. The platform may be folded and stowed beneath the floor of the van behind the rear axle. The platform further includes rollstops pivotally coupled to the ends of the platform and adapted to automatically deploy when the platform is unfolded. A pivoting housing cover is also included that is adapted to open upon deployment of the platform and close upon stowage of the platform in its housing beneath the vehicle.
摘要:
A wheelchair lift for supporting a wheelchair bound passenger and for moving the passenger between ground level and an opening in a vehicle. The wheelchair lift includes a platform and pivotal mechanism engaging the platform as well as a bridge plate for assuming a horizontal orientation to enable the passenger to proceed through the vehicle opening and a vertical orientation to act as a roll stop as the platform proceeds between the ground and the vehicle opening. The bridge plate includes a non-linear channel configured within its side which engages a pivotal mechanism which includes an upper parallelogram structure and hydraulic apparatus to move the upper parallelogram structure to move the platform. Also included is a lower parallelogram structure which is in sliding engagement with the upper parallelogram structure during at least a portion of the motion when the platform is moved between the ground and the vehicle opening. The lower parallelogram also is provided with a saddle bolt for sliding engagement with the non-linear channel such that movement of the lower parallelogram acts to raise and lower the bridge plate upon movement of the platform.
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:
A dual function, inboard barrier/bridgeplate assembly for wheelchair lifts having a stowable platform, the barrier being pivotably secured to the inboard end of the lift platform, which barrier is actuated by a link to variously raise the barrier to a safety position and lower it to a bridging position in accordance with the position of the platform. The dual function barrier/bridgeplate system is particularly useful in combination with a parallelogram type lift employing an articulated lever assembly having a sliding block for leveraging the platform from a horizontal transfer orientation to a vertical, or over-vertical stowage position. There is disclosed a barrier assembly in which a spring assist system comprising a gas spring acting on one member of the articulated lever assembly and a lever arm linking a second arm of the articulated lever assembly to the barrier co-operate to actuate the barrier from a raised position when the platform is away from the transfer level and a lowered position to act as a bridge plate at the transfer level. A telescoping push arm is included which actuates the barrier by means of a pivoted link which rotates the barrier in response to the telescoping motion of the push arm. A safety interlock and load detecting system may be employed to prevent the platform from moving to the stowed position when a load greater than a predetermined weight is on the platform. An anti-free fall mechanism is disclosed comprising a pin in the slide block which engages mating slots in the telescoping push arm members to lock their length during the initial stage of deploy of the platform downwardly from the vertical stowed position.
