Definitions

  • This invention relates to a sea anchor for mooring boats. It should be understood that the sea anchor has application not only in sea water but also in fresh water environments , such as inland lakes and waterways .
  • Temporary moorings for boats typically comprise a large mass which is located on the sea floor.
  • a chain is connected to the mass and a buoy is, in turn, connected to the other end of the chain.
  • a boat can moor at the buoy by pulling up alongside the buoy and being attached to the buoy.
  • these moorings are provided relatively close to the shore and provide a temporary mooring where boats can be moored for weeks or months before the boat moves on to another location .
  • the object of the invention is to provide a sea anchor which overcomes these problems .
  • the invention may be said to reside in a sea anchor comprising : a base for coupling with a tether having a buoy so that a boat can be moored by connection of the boat to the buoy; and at least one anchor member couplable to the base and for penetrating the sea floor by being driven relative to the base, to thereby anchor the base and therefore the sea anchor to the sea floor.
  • the base Since the base is anchored to the sea floor by the anchor member, the base can be made much lighter than conventional sea anchors , thereby overcoming the difficulties of moving and locating the sea anchor in position. Because the anchor member couples the base to the sea floor by penetrating the sea floor, the anchor member is securely installed in position and will not tend to move over the sea floor, thereby preventing any damage to the ecology of the sea floor.
  • the base includes at least one locating pin for penetrating the sea floor to locate the anchor in position on the sea floor prior to application of the anchor member .
  • the locator pin is moveable from a retracted position to an operative position, where it is able to penetrate the sea floor, so that the base can be moved with the pin in the retracted position to prevent the pin causing damage if the sea anchor base is accidentally dropped.
  • the locating pin is moveable by locating the locatable pin by a pivotal mounting so the pin is moveable between the retracted and active position by pivotal movement .
  • the sea anchor further comprises a locking member for locking the pin in either the retracted position or the active position.
  • the anchor member comprises an auger rotatable relative to the base so the auger can be rotated to penetrate the sea floor to thereby anchor the base to the sea floor .
  • the base includes a tube and an opening through which the auger can pass, the auger having a head which locates in the tube and which is not able to travel through the opening.
  • the head of the auger includes a coupling section for coupling with a tool to rotate the auger to thereby drive the auger into the sea floor.
  • the base comprises a plurality of aims, each of the arms having a respective tube and opening for receiving a respective auger .
  • the base is comprised of three arms .
  • the base includes a handle for facilitating movement of the base and for coupling of the tether to the base.
  • the sea anchor further comprises a tool for engaging the head of the auger, the tool comprising a shaft having a cooperating coupling member at one end for engaging the coupling section of the auger, the tool having a handle for facilitating rotation of the tool and therefore the auger when the tool is connected to the auger to thereby rotate the auger in the tube so the auger can penetrate the sea floor by moving relative to the tube through the opening.
  • a tool for engaging the head of the auger the tool comprising a shaft having a cooperating coupling member at one end for engaging the coupling section of the auger, the tool having a handle for facilitating rotation of the tool and therefore the auger when the tool is connected to the auger to thereby rotate the auger in the tube so the auger can penetrate the sea floor by moving relative to the tube through the opening.
  • the sea anchor further comprises a locating element for penetrating the sea floor to initially locate the sea anchor in position prior to instalment of the at least one anchor member.
  • the locating element comprises a V-shaped bracket attached to an underside of the base .
  • V-shaped brackets are attached to the underside of the base .
  • a cover for covering the base and the base has an attachment and locking member, the cover having a slot for enabling the attachment and locking members to pass through the slot so that a tether can be connected to the attachment and locking member, the base having a pair of pockets adjacent the slot so the base can be rotated to bring the pockets into registry with the attachment and locking member to thereby lock the base and cover together .
  • the locking and attachment member comprises an eyelet.
  • the eyelet is located on a boss and the slot has opposed cut-outs for accommodating the boss when the cover is located on the base.

  • a sea anchor 10 which comprises a base 12 formed from three arms 12a, 12b and 12c.
  • Each of the arms 12a-12 ⁇ is provided with a tube 14 which is angled inwardly towards the centre of the base 12 and which is hollow and registers with a respective opening 16 in the respective arm 12a-12c of the base 12.
  • the base 12 also has a generally U-shaped handle 17 which can facilitate carrying of the base 16 and also acts as a securing point for a tether, such as a chain (not shown) which has a buoy (not shown) connected to its opposite end, so that the buoy can float and provide an attachment for securing a boat to the sea anchor to thereby moor the boat.
  • a tether such as a chain (not shown) which has a buoy (not shown) connected to its opposite end, so that the buoy can float and provide an attachment for securing a boat to the sea anchor to thereby moor the boat.
  • each arm 12a-12c opposite the side to which the tube 14 is connected is provided with a respective locating pin 18.
  • the locating pin 18 is pivotally mounted in a bracket 20 which is fixed to the respective arm 12a-12c.
  • the bracket 20 has a hole 21 for receiving a longer leg 26 of a U-shaped clip 30.
  • the longer leg 26 of the clip 30 passes through a hole 19 in the pin 18 to provide a pivotal mounting for the pin 18.
  • the clip 30 can then be rotated about the axis of leg 26 and the shorter leg 29 of the clip can be located in the hole 22 and the hole 27 in the pin 18 when the pin 18 is in the retracted position, to thereby lock the pin in the retracted position .
  • a stop 31 can be located on the end of the longer leg 26 of the clip 30 to prevent the clip from being pulled out of the hole 19 in the pin 18 and the hole 21 in the bracket 20.
  • bracket 20 can be formed from two plates which are identical and which sandwich the pin 18.
  • the second plate is shown in dotted lines in Figure 5.
  • An anchoring auger 40 locates in each of the sleeves 14 with auger shaft 41 passing through opening 16 and with auger head 42 registering in the sleeve 14.
  • An auger 40 is shown in detail in Figure 6. By rotating the auger 40 relative to the base 12, the auger 40 will penetrate the sea floor and will anchor the base 16 to the sea floor. Anchoring is facilitated by the auger spiral 43 and also by the fact that the augers penetrate at an angle with respect to one another, as is best seen in the side view of Figure 2. Hence the augers 40 cannot be pulled straight out of the sea floor and the sea anchor is securely anchored to the sea floor to provide a mooring.
  • the head 42 of the auger 40 is a snug fit in the sleeve 14 so the sleeve 14 assists in supporting the auger 40 in the orientation shown in Figures 1 to 4.
  • the head 42 is provided with a cooperating member 50 in the form of a cross-slot having a first slot 51 and a second slot 52 so that the head 42 can be engaged with a tool to facilitate rotation of the auger 40.
  • the tool may be a power operated tool but more likely, because of the environment in which the sea bed will be located, is a manually operated tool.
  • Figures 7 and 8 show an embodiment of a manually operated tool .
  • the tool 60 comprises a shaft 62 having a head 63.
  • the end of the shaft 62 opposite the head 63 is provided with a cooperating tool part 66 which has four flanges 67 which engage in the cross-slots 51 and 52 so that when the tool is rotated, the auger 40 is also rotated to facilitate driving of the auger 40 into the sea floor.
  • the head 63 is provided with a hole 69 which can receive a cross handle in the form of a shaft 68 shown in Figure 7 to facilitate rotation of the tool 60 and therefore rotation of the auger 40.
  • the sea anchor 10 may also include plugs (not shown) which locate in the open ends of the tubes 14 to prevent sand or other material from entering the tubes and clogging the slots 51 and 52 of the auger 40.
  • a cover (not shown) can completely cover the top of the base and tubes 14 and be secured to the base. This will reduce the likelihood of any injuries should someone step on the sea anchor and will also protect the slots 51 and 52 of the auger 40.
  • the cover can also provide a smooth surface about which sand and other marine life can flow, thereby preventing build ups around the tubes 14.
  • the cover may have a hole through which the chain extends and will also serve to prevent unwanted disconnection of the chain from the handle 17.
  • Figures 9 to 14 show a second embodiment of the invention in which like reference numerals indicate like parts to those previously described.
  • the augers used in this embodiment are exactly the same as in the earlier embodiment and function in the same way .
  • the augers are not shown in Figures 9 to 14.
  • the base 12 has three arms 12a, 12b and 12c as in the earlier embodiment and three tubes 14 for receiving the augers (not shown in Figures 9 to 12) .
  • the underside of the base 12 includes V-shaped brackets 90 which replace the pins 18 in the earlier embodiment.
  • the brackets 90 perform the same function of providing a preliminary securing of the base 12 when the base is located in sand to hold the base in place until the augers 14 are screwed into position.
  • the brackets 90 are permanently welded to the base 12 and do not retract or otherwise move .
  • the base 12 is provided with a boss 92 (see Figures 11 and 12) which has a stem 93 which locates in a hole in the base 12 and the boss 92 is welded to the base 12.
  • An eyelet 94 is then welded to the boss 92.
  • the eyelet 94 provides a handle for lifting the base and also an attachment point for a tether (not shown) which has a buoy (not shown) so the buoy can float and provide an attachment for securing a boat to the sea anchor 10.
  • Figure 13 is a perspective view of a cover 100 used with the embodiment of Figures 9 to 12.
  • the cover 100 has a generally conical outer peripheral wall 101 and an internal cavity 102 defined by an internal conical wall 103.

  • the eyelet 94 passes through the slot section 111 with the top of the boss 92 being accommodated in the circular sections 112.
  • Located adjacent the circular sections 112 are two pockets 114 so that when the cover 100 is initially located on the base 12, the eyelet projects through the slot section 111.
  • the base can then be manually rotated 90° to bring the pockets 114 into registry with the eyelet 94 so that the eyelet 94 locates in the pockets 114 to hold the cover 100 fixed to the base 12 and to prevent further rotation of the cover 100 relative to the base 12 without manual intervention.
  • the tubes 14 are accommodated in the space 104.
  • the cover 100 when secured in place, prevents the tether from being entangled with the base 12 and the internal conical surface 103 provides a 360° surface for guiding the tether towards the surface of the water.
  • the cover 100 also provides a warning of a foot hazard and also some protection should a person accidentally step on the cover so the person does not injure himself or herself.
  • the preferred embodiments of the invention may come in different sizes depending on the actual use and, in particular, whether they are for installation in relatively shallow water or intended to be installed by contractors in deep water .
  • Embodiments applicable to deep water installation are generally much larger and the augers may be driven by a pneumatic hand tool rather than the tool shown in Figures 7 and 8.
  • Caps may be provided for location on the tops of the tubes 14 when the augers are in position to prevent build up of sand or silt in the tubes 14.
