  • Patent number: 11192763
    Abstract: A parking lift for vehicles. The parking lift includes a platform on which a vehicle can be parked and lifted by a pair of scissor-lifts configured to raise and lower the platform to enable parking of a second vehicle beneath the platform. A deck of the platform is provided with a gradual slope throughout its length to enable vehicles with low ground clearance to travel onto the platform without contacting an underside of the vehicle with the deck. Each of the scissor-lifts includes short leg and a long leg that is longer than the short leg. Upon actuation between lowered and raised positions, the legs raise an entry end of the platform a greater vertical distance than an opposite terminal end. The platform is thus tilted upward to place a deck thereof in a substantially level or downwardly sloping orientation from the entry end toward the terminal end.

  • Patent number: 8511644
    Abstract: Device that uses the force of one or several persons to help a stuck vehicle get free. It comprises a set of chains of blocks (2) to put in front of the wheels and that are connected by straps (3.6) to a system that will pull them under the wheels while pushing the car by reaction. The forces come from a lever system consisting of a main bar with a triangular part fixed underneath and near its front end. When the operator lifts the bar, the displacement of the extremities of the triangular part away from the wheels creates a pull on the straps while the front end of the bar pushes the car. The blocks become the fulcrum of this lever system. Alternately, a winch fixed on the car bumper pulls on the straps via deviation rollers or rings, transmitting the reaction pushing forces to the car rear part.

  • Patent number: 8313089
    Abstract: A lift apparatus for lifting a structure includes a base, a bell crank pivotably coupled to the base, a coupling member for engaging a portion of the structure, pivotably coupled to the bell crank device via at least one lift member, and a longeron assembly having a pivoting apex and configured to pivot about the base. The apparatus also includes a biasing device having a first end pivotably coupled to the bell crank device for applying a force thereto, the bell crank device converting the first force to a second force and applying the second force to the coupling member via the lift member for lifting the structure. A movement of the structure is compensated by rotation of portions of the longeron assembly which repositions the apex, the bell crank, and lift arm to maintain the structure in the lifted position.

  • Patent number: 8308134
    Abstract: A mobile jack is provided for a vehicle the where the mobile jack includes a movable base with a plurality of rollers adapted for moving the jack upon a generally horizontal support surface and positioning the jack under a load. The mobile jack may lift loads using a scissor assembly lying in a vertical plane where the scissor assembly connected between the movable base and an upper platform. Additionally, the mobile jack may include at least one hydraulic cylinder for actuating the scissor assembly. The mobile jack may include a safety lock for locking the upper platform in a lifted position where the lock is movable between at least one locked and unlocked position. When the upper platform is in the lifted position, the lock automatically moves to the locked position so that it cooperates with the scissor assembly to prevent the scissor assembly from lowering independent of the cylinders.

  • Patent number: 8191862
    Abstract: The present invention relates to a spring compression apparatus for compressing a coil spring and a related method of making this apparatus. A top plate is provided that engages and supports a first end of a coil spring. A middle plate engages and supports a second end of the coil spring, so that the coil spring is supported between these two plates. A base plate is disposed on an opposite side of the middle plate from the top plate. A frame is formed that fixedly supports the top plate and the base plate. The frame also slidably supports the middle plate. A jack, which is positioned between the base plate and the middle plate. The jack urges the middle plate toward the top plate, so as to compress the coil spring.

  • Patent number: 8160475
    Abstract: This involves a cart that can be used in changing a marking module in a xerographic color marking system. The cart has a lifting mechanism securely attached to its upper surface. When the marking module is to be changed and a new replacement module installed, the lifting mechanism is used to support the marking module during each of these procedures. Since the marking modules are relatively heavy (30-35 lbs.), to prevent accidental damage to the module, the cart and its attached lifting mechanism are conveniently used by the customer. The lifting mechanism is made up of an upper cradle, a bottom plate attached to the cart and a movable linkage. The module securely rests in the cradle in both removal and installing operations. It is not uncommon for a customer to want to change a color or colors in one or more modules. This cart and its attached lifting mechanism makes it relatively easy to accomplish this change.

  • Patent number: 8081901
    Abstract: This invention provides a xerographic marking module that has a built-in lifting mechanism that is useful in installing a new module in a xerographic marking system. The lifting mechanism forms the bottom portion of the marking module and comprises an upper cradle to hold the remaining module portion, a lower plate that constitutes the bottom of the module when in a collapsed position, and a movable linkage that connects the cradle to the lower plate. When in installation mode, the linkage creates a vertical force which will upwardly push the cradle (holding the module) away from the lower plate into an installation elevation. After slides in the module and in the color marking system are mated, the lifting mechanism is collapsed and the module pushed into the color marking system or apparatus.
