Definitions

  • the present invention relates to a fender device for boats.
  • US 6161494 A describes a fender device comprising a body adapted to protrude from the side of a boat and to inflate.
  • the inflatable body is located, at rest, in a housing inside the boat communicating with the outside with an opening closed by a hatch that can be opened on command.
  • the above cited patent does not explain how the hatch can be made and how it can be opened on command in relation to the operation of the inflatable body.
  • French patent 2896227 discloses a hull protection device comprising an inflatable element, which is in the deflated state inside the hull, and in the inflated state outside the hull.
  • the device includes maneuvering means for moving the inflatable element between an internal position and an external position.
  • the inflatable element In its free end, the inflatable element has a cap which forms a closure of the side when the inflatable element is retracted inside the hull in a deflated position. The cap does not constitute an adequate closure of the side.
  • US 9038556 describes a concealable fender assembly comprising a fender and a cover having a shape compatible with the shape of the side of the hull of a boat in closed position.
  • the assembly also has a mechanism for actuating the cover for closing and opening thereof with respect to the side of the hull.
  • the cover is associated with the fender so that when the cover is in open position the fender outwardly extends from boat hull lateral surface. The fender is always swollen.
  • US 2010/0031862 A1 discloses an inflatable fender comprising an enclosure mounted on or in the boat hull and connectible to a fluid supply, an inflatable flexible member mounted within the enclosure and capable of extending therefrom when inflated by fluid supplied into the enclosure, and separate retraction means associated with the enclosure and operable to withdraw the inflatable into the enclosure when deflated.
  • US 2010/0031862 A1 provides various embodiments, almost all external on the side of the boat; these involve a modification of the side of the boat to provide for the protruding housing of the flexible member. Other embodiments that have a housing inside the boat, provide means for withdrawing the flexible element into the housing and a closing cover hinged in the side that closes after the flexible element has returned into the housing.
  • the present invention aims to overcome the drawbacks mentioned above.
  • the main purpose of the present invention is to provide a fender that can be deployed in working position by actuating an opening of an exit port of the fender from the side of the boat and can be withdrawn to rest position by actuating a closure of the same exit port.
  • Another object is to provide an opening and a closing of the exit port automatically performed in conjunction with controlling the deployment and the withdrawal, respectively, of the fender by operation means.

  • a speed of rotation different from that of the drum 40 determined by the second motor 55 can be selected for the rotation of the upper rollers 58 and lower rollers 59 so that the upper rollers 58 and lower rollers 59 engage with the fender assembly 2 in order to allow uniform advance and regression.
  • the operation of the second motor 55 is limited by limit switches, preferably inductive, which can be positioned in the vicinity of the winch shaft 41.
  • the door 1 of the passage opening of the fender assembly 2 is first shown closed. Then ( Figure 2 ), the door 1 begins to open being operated by the control panel of the console thanks to the motor 52 which, by means of the transmission shaft 19, with the bevel gear formed by the first bevel wheel 190 and the second bevel wheel 191 and the endless wheel 18, drives the racks 15 sliding on the side walls 500, 501 of the container 5 of the fender device.
  • the fender assembly 2 begins to come out thanks to rotation of the winch drum 40.
  • the fender assembly 2 is completely extracted in the deflated condition, thanks to the drive of the motor 55 of the winch 4 and to the motor 57 which moves the plurality of upper rollers 58 and lower rollers 59, and hangs from the boat side F with its pressure hose 3.
  • Figure 5 shows the fender assembly 2 inflated by the compressed air generator and
  • Figure 6 shows the fender assembly 2 in working position with the door 1 completely closed.
  • the pressure hose 3 can be unwound from the drum to the extent necessary to position the fender assembly at the required height.
  • the fender assembly 2 When the fender assembly 2 has to be withdrawn inside the hull, it is deflated and rewound on the drum 40 of the winch 4 by the motors 55 and 57 which work in the direction opposite to that of the deployment, until the stop determined by the inductive sensors.
  • the fender device according to the present invention also to reduce its weight, is made in its components, such as gear wheels, bearings, bushings, wheels and worm screws, bevel gears and racks, in Teflon (PTFE), an anticorrosive material with excellent mechanical performance.
  • PTFE Teflon
  • the rubberized rollers are made with the injection moulding process of ABS or other suitable thermoplastic polymer and coated with polyurethane rubber to increase the grip.
  • the container 5, the sealed compartment of the engines and the winch 4 can also be made with thermoplastic polymers for injection moulding.
  • a prototype was made with the following maximum measurements: width 14 cm, height 17 cm, depth 17 cm. It should be understood that the container 5 has very small dimensions and takes up minimal space inside the boat. The door could be even smaller than the container 5, for example 15 cm wide and 5 cm high. Thanks also to its small size and its compact and per se complete structure, the fender device can be applied easily and quickly on newly built boats or, with minor modifications, even on already built boats.
  • the fender device provides the advantage to a person of being able to deploy a desired number of fenders on the boat side as needed with simple commands from the control panel of the boat and subsequently to withdraw the fenders always with remote control, without leaving the control panel. Thanks to the invention, the boat sides maintain their traditional appearance that is substantially unchanged both with fenders deployed from the boat sides and with fenders withdrawn inside the boat.
