Definitions

  • the present invention relates to a weight device for an anchor line that extends between a boat and an anchor.
  • An anchor is used to connect a boat or a vessel to a sea bed or bottom of a lake in order to prevent the boat/vessel from drifting due to current or wind ( figure 1 ).
  • an anchor there is always a risk that the anchor loses its grip on the sea bed. The upward pulling forces on the anchor line from the boat may cause the anchor to loosen, whereafter the boat starts to drift. This is especially true in rough wind and weather conditions.
  • anchor weight devices have been developed.
  • the aim of these devices is to position the anchor line from the anchor parallel to the water bed before extending in a more upward direction towards the boat.
  • Examples of such weight devices are disclosed in DE9301099 , SE411032 and WO8102413 .
  • the more horizontal orientation of the anchor line reduces the upward pulling forces on the anchor. This reduces the risk for the anchor becoming detached from the sea bed. This also increases the possibility for the anchor to fasten again on the water bed after having been detached.
  • anchor holding devices improve the safety of a boat.
  • weight devices may be a double anchor attached to the anchor line at a distance from each other as shown in US2008245287 .
  • Another alternative is the use of lead attached to the anchor line.
  • Other holding devices can be attached to the anchor line prior to use. Many of these devices comprise screwing part and/or complex locking mechanisms to attach the holding device to the anchor line.
  • DE20017299 describes a weight device with a locking mechanism that can be opened to attach the device to the anchor line.
  • AU731379BB2 also discloses an apparatus for assisting anchoring of boats comprising a weight having a channel for receiving an anchor line.
  • SE520 239 describes a mooring device comprising a holder arranged around a rotatable wheel and having two arms extending under the wheel, whereby a weight is attached to one of the arms.
  • An opening for receiving an anchor line is defined between the wheel and the arms under the wheel.
  • a mooring line can be attached to the holder.
  • the holder can be opened and closed using a lock positioned on the arms under the wheel.
  • a disadvantage with this device is that opening and closing of the device it can be troublesome. In particular when the sea is rough, and the boat is moving up and down, and it can be tricky to open and close this device.
  • the anchor weight device comprises a weight element having an upper surface.
  • a holder is attached to the weight element, and preferably extending upwardly from the upper surface of the weight element.
  • the holder may extend in a direction that crosses a plane defined by the upper surface of the weight element.
  • the anchor weight device also comprises a wheel that is rotatably arranged in relation to the holder and disposed at a distance from the upper surface of the weight element.
  • a first space for receiving an anchor line is formed between a peripheral surface of the wheel and the upper surface of the weight.
  • the anchor weight device is characterized in that the anchor weight device comprises a shackle comprising an intermediate part and a first and a second leg extending from the intermediate part on opposite sides of the wheel and ending at a distance from the peripheral surface of the wheel, and the shackle is rotatably connected to the holder so that the shackle is rotatable between a closed position in which at least one of the legs extend between the wheel and the upper surface of the weight element to secure the anchor line housed in said space, and an open position in which said at least one leg is moved away from the upper surface of the weight element so that an opening is formed between the shackle and the upper surface of the weight element to allow the anchor line to enter or leave said space.
  • the shackle is arranged rotatable between an open position in which an opening is formed between at least one the legs and the upper surface of the weight element, and a closed position in which the legs extend towards the weight element close the opening and by that secure the anchor line in the space.
  • An advantage with the invention is that the device can easily be opened and closed by simply rotating the shackle between the first and second position. In addition, it is possible to close the device at a distance from the device by simply pulling a rope attached to an upper part of the shackle.
  • the intention of the weight device is to change the angle of the tensile force on the anchor to an essentially horizontal tensile force instead of an essentially vertical tensile force causing the anchor to adhere better to the bottom of the sea. Further, the strain on the anchor is reduced due to a spring effect achieved by the device, which absorbs the weight of the boat, when waves and wind moves the boat up and down in relation to the anchor.
  • the weight device is intended to be rolled out on a stretched anchor line that extends between a boat and an anchor.
  • the device is adapted to be slidably connected to the stretched anchor line.
  • the weight device comprises a shackle that is rotatably arranged in relation to the weight element between an open position, in which an opening is formed between the shackle and the weight element to allow the stretched anchor line to enter and leave the space, and a closed position in which the opening is closed, thereby preventing the anchor line from leaving the space.
  • the device can be slidably connected to the stretched anchor line by simply rotating the shackle between the open and closed positions.
  • the anchor weight device of the present invention comprises a separate shackle for this purpose. This improves convenience for the user and allows the device to be used by one person. This also reduces wear and tear of the device and allows the device to remain compact with reduced size, easy to use and store.
  • the shackle When the shackle is in the open position relative the weigh element, it is possible to enter the anchor line into the space through the opening formed between the shackle and the upper surface of the weight device, and to remove the anchor line from the space through the opening.
  • the opening is closed and the shackle, the wheel and the weight element form a closed structure with a through hole for the anchor line to pass through.
  • the weight device is permitted to move relative the anchor line in a longitudinal direction of the anchor line when the shackle is in the closed position. However, the weight device is not permitted to be moved away from the anchor line when the shackle is in the closed position.
  • the anchor weight device is a simple and robust construction comprising a few parts and can be manufactured at relative low cost.
  • the device does not comprise any complex screwing or locking means. Such means may become affected by sand or mud from the water bed, which reduces the lifetime of the device.
  • the anchor weight device can easily be operated by one person on a vessel.
  • the anchor weight device can be attached and detached on any type of anchor line, such as a chain or a rope. When the anchor weight device is not used, the device can easily be stalled in the vessel without occupying much storage room.
  • An anchor line is an elongated and bendable element, for example, a wire, a chain, rope, belt or string.
