  • Patent number: 6899185
    Abstract: A beach cleaner that is simple in configuration and light in weight and can be manufactured at a low cost. The beach cleaner is easy with regard to maintenance and inspection and can efficiently reclaim various kinds of refuse scattered on a beach. A beach cleaner includes a traveling body with ski members disposed at four corner portions of a frame having a substantially quadrangular shape. The beach cleaner is towed along a surface F of sandy soil by a traction vehicle R. A bar-like scraper is provided at a lower portion of a front portion of the traveling body and extends in a widthwise direction of the traveling body through a scraper supporting member for scraping up refuse on the sandy soil while the traveling body is operating. A refuse reclamation section is provided on the traveling body rearwardly of the bar-like scraper for collecting pieces of refuse scraped up and thrown rearwardly by the bar-like scraper onto a net member.

  • Patent number: 6857479
    Abstract: A beach cleaner for recovering waste while moving in a towed state by a traction vehicle. A grating-like portion scoops up waste present in front of the beach cleaner as the beach cleaner is moved and a reticulate portion that is formed behind the grating-like portion to hold waste. As the beach cleaner is moved, waste present in front of the beach cleaner is scooped up onto the grating-like portion and is held with the reticulate portion formed behind the grating-like portion. Sand that is scooped up together with the waste is allowed to drop through the gaps in the grating-like portion.

  • Patent number: 6763949
    Abstract: A waste recovery station for a beach cleaner for recovering waste raked up by a beach cleaner. A waste recovery station for a beach cleaner includes a pair of station members arranged in parallel with each other through a required spacing. Each station member is provided with a pair of support posts with a foot such as, for example, a circular or square flat plate fixed to a lower end of each support post and is also provided with a guide member fixed to upper ends of the support posts. In the guide member, a longitudinally intermediate portion is formed as a horizontal portion and front and rear end sides are formed as slant portions and are bent downwardly at an obtuse angle. The beach cleaner A is lifted by the guide members while passing between the station members, whereby waste caught on rakes is allowed to drop onto the sand.

  • Patent number: 6640906
    Abstract: A beach cleaner for recovering waste while traveling in a towed state by a traction vehicle. A grating-like portion scoops up waste present in front of the beach cleaner as the beach cleaner is moved. A rotor is disposed on an upper side of the grating-like portion and is adapted to rotate so that a lower portion thereof moves rearwardly. The rotor is mounted on a rotary shaft extending in the transverse direction of the beach cleaner. Waste is delivered rearwardly between the rotor and the grating-like portion. With travel of the beach cleaner, waste present in front of the beach cleaner is scooped up onto the grating-like portion and sand which is scooped up together with the waste is allowed to drop through gaps in the grating-like portion.

  • Patent number: 6634434
    Abstract: A beach cleaner for traveling on sandy soil while being towed by a traction vehicle for recovering waste such as empty cans scattered on the sandy soil. The beach cleaner is provided with a travel body. The travel body includes a plurality of longitudinal members arranged in a hurdle shape spacedly and extending in a travel direction and also having in a front portion thereof a portion to be pulled by the traction vehicle. A flat plate-like scraper for scraping up waste together with sand during travel of the beach cleaner is provided in the front portion of the travel body. A net for separating waste from a mixture of sand and waste scraped up by the scraper and for storing the thus-separated waste thereon is stretched on an upper surface of the travel body.

  • Patent number: 6612374
    Abstract: A beach cleaner for recovering waste while being towed by a traction vehicle. The beach cleaner includes a grating-like portion for scooping up waste present in front of the beach cleaner as the beach cleaner is moved. The grating-like portion is inclined so that the front side thereof assumes a lower position. A rotor is disposed on an upper side of the grating-like portion and for rotation so that a lower portion thereof moves rearwardly. The rotor is centered on a rotary shaft extending in the transverse direction of the vehicle. The rotor delivers the waste rearwardly between the rotor and the grating-like portion. A reticulate portion is formed behind the grating-like portion. The reticulate portion is inclined so that the rear side thereof is located at a lower position to hold waste.

  • Patent number: 6540030
    Abstract: Waste scattered on a sandy beach is recovered in a clean and efficient manner by using a beach cleaner of a simple structure. In a first waste recovery step, a first beach cleaner A is allowed to travel on a sandy beach while being towed by a self-traveling vehicle R, whereby waste G1 such as string-like waste and other elongated waste is caught on rakes and conveyed to a waste recovery area. In a waste recovery station the first beach cleaner A is lifted to recover the waste. In a second waste recovery step, while a second beach cleaner is allowed to travel by the self-traveling vehicle, waste such as cans which have not been recovered in the first waste recovery step are scooped up in a waste conveying section, and are then collected in a waste collecting section by means of scraping blades and are recovered in a waste recovering area.

  • Patent number: 6519937
    Abstract: A hydrostatic continuously variable transmission includes a fixed capacity hydraulic pump and a variable capacity hydraulic motor, connected by a hydraulic closed circuit. A control system and method for the variable transmission provides a good deceleration feeling when going downhill. In accordance with the control system and method, a range of a selected gear is determined. Next, it is determined whether the vehicle is in an automatic gear shift mode. If these conditions are met, it is then determined whether or not certain criteria for descent control are satisfied. The certain criteria may include: (1) whether the throttle is closed; (2) a speed or acceleration of the vehicle; (3) whether the acceleration exceeds a threshold; and (4) whether simultaneous satisfaction of conditions (1)-(3) exist for a period of time exceeding a fixed time. If all of the criteria are satisfied, the gear ratio is shifted by a specified amount towards a LOW side.
