Grip Or Plow Traps Patents (Class 104/145)
  • Patent number: 9637018
    Abstract: Disclosed is a road for charging electric vehicle. The road includes an electrified rail which includes an electrode plate for connecting an electric plate of the electric vehicle, an insulated cover covering on the plate electrode so as to prevent electric leakage and a neutral layer covering on the insulated cover for connecting a neutral electrode plate of the electric vehicle. The electrode plate includes a first electrode plate and a second electrode plate. The first electrode plate is disposed above the second electrode plate and between the first electrode plate and the second electrode plate there is a gap so that the electric plate of the electric vehicle is able to be sandwiched between the first electrode plate and the second electrode plate while charging. According to the present invention, the road surface is provided with electrified rail, thus the electric vehicle can charge while driving.

  • Patent number: 8613255
    Abstract: A mass transit monorail uses an I-beam rail structure having an upper flange portion spaced apart from a lower flange portion, the flange portions joined by a vertical web portion. A frame of a vehicle has a pair of supporting wheels contacting the rail on a first side at an intersection of the web portion with the lower flange portion. A third wheel contacts the upper flange portion on a second opposing side of the rail. The vehicle moves along the rails which form a semi-continuous in-line track. A plurality of such tracks are positioned in parallel to make up a transport corridor with plural right-of-ways where vehicles may move in opposite directions passing each other. The rails are flexible enough to enable a vehicle to move from one semi-continuous in-line track to an adjacent semi-continuous in-line track.

  • Patent number: 7802666
    Abstract: A device for protection and handling of electric feed cables (20-20?) for mobile use, especially for a mobile device (26-26?) for lifting and moving loads such as cranes, bridge cranes and the like installed along harbour docks. The device includes a mobile frame (10-10?), made of metal or other suitable material, provided with a central tower (30-30?) connected to said mobile device and with opposite arms (32-32?), arranged in alignment on a part of a trench duct or raceway (12-12?) buried in the ground with an open top substantially aligned with the surface level (14-14?) and screened by a flexible tape (16-16?). At least one of the opposite arms (32-32?) is provided with structure for lifting the flexible tape (16-16?), arranged at the top and/or at the bottom of the tape, and structure for guiding and centering the frame (10-10?) in cross direction relative to the raceway (12-12?).

  • Patent number: 6829999
    Abstract: A device for towing a train of carriages of a sorting machine includes a pair of wheels driven by respective motors, which wheels engage a blade arranged below the carriages. Each towing wheel is movable toward and away from the blade relative to its respective motor, whereby the inertia of the member that has to be moved in response to a misalignment of the blade is low.

  • Patent number: 5016540
    Abstract: A portable amusement ride incorporates a multi-functional trailer which can serve for hauling the amusement ride, when disassembled, and serve as an elevated track portion of the ride, when assembled. Electrically powered vehicles are guided and powered over an electrified track having a main enclosed path, and an alternate loading area for discharge and pick up of passengers. Automatic launch and vehicle exit features between the main path and loading area prevent vehicle collisions, with minimum requisite operator activity. A pick-up assembly carried on the vehicle both guides and electrically powers the vehicle as it moves over the track. The track has an electrified pair of members also forming a guidance channel in which the pick-up assembly from the vehicle is received. The configuration of the pick-up assembly and its interaction with the electrified guidance channel causes proper electrical pick-up substantially regardless of the terrain formed by the track over which the vehicle travels.

  • Patent number: 4129203
    Abstract: Apparatus and a system are provided for a trackless-roadway vehicle having internal and external propulsion energy sources; the external energy being obtained by a collector plow from electric power rails located in a conduit below the roadway. The collector plow, sensors, the plow elevating mechanism, and the plow steering mechanism are mounted on a laterally movable carriage on the underside of the vehicle. By means of servo-systems comprised of sensors, servo-amplifiers, and drive motors with associated gearing, the plow is automatically and continuously translated and orientated to maintain the plow arms in the vertical plane of the slot in the cover of the conduit. The plow consists of two arms, each with a contactor. When the plow is out of the conduit, the contactors lie in a single plane so that they may pass through the slot. After passing through the slot the contactors are brought to bear on the power rails by contra-rotation of the plow arms.
