- ABSTRACT A boat docking device for being mounted on the bow of a boat comprises a housing member having forward surfaces slanting inwardly to a slot for receiving 21 51 lm.
- B63B 21/04 [58] Field of Search 114/230, 210; 294/84, 83 R; 2 238, 232, 241 PS, 241 SL, 241 PP, 241-513 mooring line, a latch pivotally mounted in the housing References Cited member between a locked and unlocked posltlon. and UNITED STATES PATENTS a retractable biased pin urged against the locking 1 /1891 member for securing the latch in a locked position.
- FIGURE 2 is a diagrammatic representation of FIGURE 1
- a crew member For this purpose, a crew member must be stationed on the dock, frequently requiring a crew member to jump from the boat to the dock. Moreover, where such a crew member is not available, the operator must drive the boat into the slip and as the bow nears the forward slip end, reverse the drive prop until the forward boat movement is stopped and then single handedly secure the mooring or docking lines. Such a procedure is made even more difficult in a wind or a current.
- a boat docking apparatus has been proposed in U.S. Pat. No. 3,177,839.
- a crew member must be present on the dock in order to disengage the device when the boat is to be launched. Again, if such a crew member is not available, launching may be difficult.
- the device is mounted on the dock and if care is not taken when entering a slip, damage may occur either to the device or the boat.
- the device of the present invention is designed to allow a boat operator toenter a dock and secure a mooring line to the boat bow automatically without requiring assistance of a crew member.
- the device also allows the operator to launch the boat without requiring assistance of removing bow and stem lines immediately before launch and prevents the boat from being adrift in the slip prior to unlocking the device from a mooring line.
- the device is relatively simple, having few moving parts and components, is easy to assembly and install on a boat bow. Another feature allows for remote unlocking from the cockpit of the boat.
- FIG. 1 is a side elevational view partially cut away showing the device in a locked position
- FIG. 2 shows the device in an unlocked position
- FIG. 3 shows the device installed on a boat moored in a slip
- FIG. 4 illustrates another embodiment of the invention secured in a modified boat bow.
- FIGS. 1 and 2 there is shown the docking device of the invention including a housing member 10 having a cavity 40 and a locking member or latch 12 received or disposed within the cavity.
- the latch is pivotally mounted to the housing member by a pivot rod 20 which may comprise a bolt secured to the housing member and extending through cavity 40.
- a nut (not shown) may be threadedly engaged on one end of the bolt thereby securing it to the housing member.
- a hole 21 through latch 12 is for the purpose of allowing the latch,to;rotate or pivot .on pivot rod 20.
- Housing. member 10 has an upper portion 16 and lower portion 14 each having a forward surface 17 and 19, respectively, which slant inwardly toward a slot 22 formed in the housing member.
- the rear surface 48 of upper portion 16 will abut the forward bow surface on the angle shown, it being understood that the average bow rake is about 55 from horizontal.
- lower portion 14 of the housing member will extend outwardly from the bow surface at an angle of between about and about The purpose for so extending the lower portion from the bow is to form an arm which will pick up a mooring line stretched across a dock and direct it into slot 22 as a boat moves forwardly into the line.
- forward surface 17 of upper portion 16 also slanting toward slot 22 acts as a guide surface where the mooring line is elevated somewhat.
- forward surfaces 17 or 19 guide a line into slot 22 during boat docking and as will be more fully explained hereinafter.
- a sleeve member 30 which can be threadedly engaged as shown so as to be firmly secured to the housing member.
- a hole or orifice extending through the back of the housing member and into cavity ,40 has an enlarged threaded portion 32 into which sleeve 30 is threadedly engaged and an unthreaded portion 31 which is large enough to allow pin 26 to freely pass therethrough.
- sleeve 30 can be tightened into the threaded portion of the orifice.
- Pin 26 slideably received in sleeve 30 preferably has a slender forward portion which is received in notch 24 of latch 12 when the device is to be locked, and an enlarged upper portion 28 of a diameter at least slightly smaller than the internal diameter of sleeve 30 for easy sliding of the pin within the sleeve.
- the purpose for the enlarged pin portion 28 is to ensure guidance of the pin within sleeve 30.
- the length of the pin extending into cavity 40 should be sufficient to be against the cam surface 15 of latch 12 as shown in FIG. 2.
- a biasing member in the form of spring 36 is located behind or at the end of the pin so as to bias the pin toward latch 12 and maintain the pin against the latch.
- the cam surface 15 has a gradually decreasing radius therealong between pivot rod 20 and the surface from the edge of notch 24 and the cam surface along which the end of pin 26 travels as the latch rotates to the unlocked position.
- the device also includes an adjustable end cap 38 for sleeve 30 which may be threadedly engaged for varying the compression of spring 36 depending on the extent to which the cap is screwed on the sleeve.
- spring 36 lies between the end of pin 26 and cap 38.
- the cap also has an orifice or hole to allow a wire or cord 34 to extend therethrough and which wire is connected to pin 26 by screw 39 for retraction thereof when the device is to be unlocked.
- the opposite end of wire 34 can be extended by suitable means to any desired location in the boat, for example, the cockpit, so that the boat operator, by pulling wire 34, can retract pin 26.
- Latch 12 is shaped so that an enlarged finger portion 13 is located forwardly of pivot rod so that when pin 26 is retracted from notch 24, the latch will fall or rotate gravitationally due to the mass of the enlarged portion 13 to the open position shown in FIG. 2.
- Located along the rear edge 15 of latch 12 is a notch 24 to receive pin 26 for locking the latch in the position shown in FIG. 1 when the latch has been rotated with enlarged finger l3 raised to close slot 22 in which a mooring line is received.
- the forward surface of latch member 12 is also grooved and which grooved surface extends into notch 22 in the housing member for contact with a mooring line directed into the slot.
- the device is secured to a boat bow by sleeve 30.
- a shaft or hole will be bored through the boat bow and sleeve secured therein by any convenient means such as a nut 37 threadedly engaging sleeve 30.
- the sleeve is threadedly engaged with the housing member of the device and turned until surface 48 snugly abuts against the bow.
- the upper portion 16 of the housing member can be V-cut along surface 48 as illustrated in FIGS. 1 and 2 so as to conform to the shape of the bow along the abutting surfaces. Additional securing means such as screws or bolts extending through the housing member into the bow may also be used as desired and which does not affect the operation of the device.
- brackets or other securing members attached to the boat and housing member may also be utilized but are generally not required. After securing the housing member on the bow, nut 37 is tightened snugly against the interior bow surface. It will be understood that sleeve 30 is of a length sufficient to extend through the bow with sufficient threads exposed on the interior end to secure nut 37 and cap 38.
- wire 34 may be extended conveniently through the boat utilizing blocks or eyelet types of guide members and with the opposite end of the wire terminating at a handle or the like conveniently located for being pulled by the operator.
- a mooring line 46 is stretched between cleats 44 and 45 secured to a dock across a boat slip.
- the mooring line usually a rope, need not be taut and preferably has some slack so that it will be approximately 12 to 18 and preferably about 14 to 16 inches above the water line at its lowest point, it being understood that the dock surfaces are normally about 2 feet above the water line.
- the operator need only make sure that the device is in the unlocked position by simply pulling knob 52 which is attached to the end of wire 34, and conveniently located in the cockpit, for example, at the console as shown in FIG.
- the operator can automatically secure the mooring line to the bow without requiring assistance on the dock while the boat is moving in the slip. Moreover, where the mooring line is fastened sufficiently away from the end of the dock, there is no danger that the boat bow can become inadvertently bumped against the dock since the mooring line will limit the forward movement of the boat when it is secured in the docking device.
- FIG. 4 Another embodiment of the invention is shown in FIG. 4 in which a boat bow has been modified and formed for mounting latch 12 in cavity 40.
- the bow itself forms the housing member with sleeve 30 mounted through an orifice in the bow and secured with nut 37, the other numbered components being the same as those referred to in FIGS. 1-3. Since there is no lower housing member portion for picking up and guiding a mooring line into slot 22, the upper bow surface 51 will serve that function.
- the device can be used to secure a boat to a trailer with a rope secured on the trailer and the device operated for docking or launching.
- a locking member pivotally mounted in said housing member between a locked and unlocked position having a finger portion at one end thereof for closing said slot in a locked position, a surface exposed in said slot in an unlocked position, said locking member pivoting to a locked position when pressure is exerted against said exposed surface in the direction of said bow and to an unlocked position when pressure is exerted against said finger in the direction away from said bow;
- said lower housing member portion comprises an arm extending outwardly from the boat bow and at an angle of between about 70 and about 110 relative thereto.
- the device of claim 1 including a spring for biasing said pin.
- the device of claim 7 including a sleeve member in which said pin is slidably received, said sleeve member being secured to said housing member.
- a boat having a slanted bow and the device of claim 12 the upper portion of said housing member being secured on said bow with said sleeve member being mounted through said bow.
- a boat bow having a slotted cavity therein, a locking member pivotally mounted in said cavity between a locked and unlocked position and having a finger portion at one end thereof for closing said slot in a locked position and a locking notch, said locking member having a surface exposed in said slot in an unlocked position and pivoting to a locked position when pressure is exerted against said exposed surface in the direction of said bow, and pivoting to an unlocked position when pressure is exerted against said finger in the direction away from said bow, a retractable biased pin extending in said housing member urged against said locking member and received in said notch when said locking member is in a locked position, and means for retracting said pin from said notch.
