Document Type and Number:
Japanese Patent JP6816641
Kind Code:
B2
Abstract:
In a vehicle lifting device, a damper for exerting a force in an upward direction on a lifting body is provided in order to enable a platform loaded with goods or people to be lifted and lowered by manpower. However, a large operating force is required to overcome the force of the damper in the vicinity of the lifting position to perform the descending operation. An object of the present inventionis to provide a manually operated lifting device having a lifting body which is forced in an ascending direction, which can reduce an operating force of a descending operation of the platform, and which can easily lower the platform from an ascending position to a descending position by manpower. A lever (50) extending in the longitudinal direction of a first link (21) is arranged integrally withthe first link (21). A small operating force for operating the lever (50) is increased by using the lever principle, whereby a four-bar linkage (20) can be operated against the force of the damper (25), and the platform (3) can be lowered.
