Definitions

  • the invention relates to a vessel mast comprising a tube provided with a lower end, with which the tube can be secured to a deck of a vessel.
  • a sail or cloth can be attached to the vessel mast to span part of the deck to create a shaded area.
  • Such a vessel mast is generally known.
  • the known vessel mast is provided with one or more fastening eyes to which one or more cords can be fastened, which are attached to a sail or cloth.
  • An object of the invention is to provide a vessel mast to which one or more sails or canvases can be attached in an advantageous manner.
  • the vessel mast according to the invention is characterized in that it furthermore comprises a pneumatic cylinder and a piston with an associated piston rod being displaceable in the cylinder, the pneumatic cylinder and piston with the associated piston rod being in the tube and being secured to the tube, a cord is attached the piston rod which cord exits through a passageway in the tube and can be attached to a sail or cloth.
  • the sail or cloth By attaching the sail or cloth to a piston rod of a pneumatic cylinder, the sail or cloth can be pulled taut and kept taut by the cylinder and forces on the sail or cloth due to gusts through the cylinder can be damped, so that the risk of overloading the tube or the deck of the vessel is reduced.
  • the pneumatic cylinder is part of a gas spring, preferably a gas pull spring.
  • the pneumatic cylinder is connected to an air pump or compressed air container and the gas pressure in the cylinder is adjustable by means of control valves present between the air pump or compressed air container and the cylinder.
  • the gas pressure in the cylinder can furthermore be kept constant by a control unit connected to the control valves.
  • the vessel mast comprises a further cylinder and a further piston with associated further piston rod movable therein, which further piston rod is attached a further cord, which exits via the passage or a further passage and can be attached to a further sail or a further cloth, or can be attached to the sail or cloth at another place.
  • the cylinder and the further cylinder are preferably arranged in line and the piston has a hollow piston rod through which the further piston rod of the further piston extends.
  • An embodiment of the vessel mast according to the invention is characterized in that it furthermore comprises a pressure cylinder with a pressure piston with associated pressure piston rod movable therein, which can be coupled with a securing device for securing the vessel mast to a deck in order to press or pull the securing device free from play.
  • the pressure piston projects downwards from the lower end of the tube and the piston and further pistons project upwards from the cylinders.
  • the pressure cylinder and the cylinder are preferably arranged in line.
  • FIG. 1 shows a longitudinal section of an embodiment of the vessel mast according to the invention.
  • the vessel mast 101 has a tube 103 secured with an open lower end 103A in a deck 201 of a vessel and provided with passageways 105 and 106 for cords 112 and 114 attached to a sail or canvas.
  • the tube 103 there are two cylinders 107 and 111 in line one behind the other with movable pistons 109 and 113 therein with piston rods 108 and 110 attached thereto.
  • Cords 112 and 114 are attached to the piston rods which lead to the outside via passages 105 and 106 and to which one or more sails or canvases can be attached.
  • the piston cylinders keep the sail or canvas or sails or canvases taut and dampen forces due to gusts of wind on the sail or canvas or sails or canvases.
  • a pressure cylinder 115 In the lower end 103A of the tube 103 there is also a pressure cylinder 115 and a pressure piston 117 movable therein with pressure piston rod 118 attached thereto, as well as a securing device 119 with which the vessel mast 101 is secured to the deck 201 of a vessel.
  • the pressing cylinder 115 is attached to the locking device 119 and the pressing piston rod 118 extends downwardly and is coupled to a part of the locking device 119 to ensure that the locking device cannot be unintentionally disengaged.
  • the piston rod 108 is hollow and the piston rod 110 extends through the piston rod.
  • the two pistons 109 and 113 extend upwards in the tube 103.
  • the pressure cylinder 115 and the cylinders 107 and 111 are all in line. Between the pressure cylinder 115 and the cylinders 107 and 111 are valves for directing air to and from the pneumatic cylinders.
  • FIG. 2 schematically shows the lower part of the vessel mast.
  • an air pump 121 is arranged which can change the gas pressure in the cylinders via control valves 123, 125 and 127.
  • the gas pressure in the cylinders 107 and 111 can be kept constant by a control unit 129 connected to the control valves 123, 125 and 127, which is also connected to the air pump 121.
  • the invention has been elucidated in the foregoing with reference to the drawings, it should be noted that the invention is by no means limited to the embodiment shown in the drawings. The invention also extends to all embodiments deviating from the embodiment shown in the drawings within the framework defined by the claims.
  • the pneumatic cylinder or pneumatic cylinders for keeping the sail taut can also be designed as a gas spring.
