Title: Retractable Docking Line

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates generally to mooring assemblies for marine vessels and the ability to secure the vessels when docked. More specifically, the present invention includes an automatically retracting assembly for a mooring line, wherein the assembly includes a user interface for storing the distal end of the mooring line, an auto-retracting reel, and optionally, a conduit to connect the user interface and reel, wherein mooring line is wound around the reel and the free, looped end of the mooring line is stored in the canister when not in use. Docking a marine vessel typically involves numerous lines that must be tied between a boat and a dock, pier or the like, and can take up time to secure a vessel to a dock. This configuration is particularly useful in keeping the mooring lines organized and easily accessible for allowing a user to quickly and effectively secure a vessel to a dock. 
     Heretofore, many efforts have been made to provide assemblies and mechanisms for effectively secure marine vessels to docks. Some examples are set forth hereinbelow, and each of the following references are incorporated herein by reference, in their entireties:

The housing also has a line locking mechanism to hold the line at the pre-selected length so as to prevent the boat from drifting away taking line with it. 
     BRIEF SUMMARY OF THE INVENTION 
     In accordance with one aspect of the invention, a first embodiment of a device for storing and dispensing line used to moor a boat includes a user interface canister, an auto-retracting reel assembly, and conduit connecting the user interface to the reel assembly. The user interface (also referred to herein as a “user interface canister”) includes a canister having a top lid, rail support having a catch, button, and lid springs, locking nut, stopping collar, and a bottom lid. The top lid sits on top of and slides horizontally along the rail support to open and close. The mooring line is wound onto the auto-retracting reel assembly and the looped end of the mooring line is stored in the canister of the user interface until it is ready for use. When a user is ready to dock the vessel, he may slide the top lid along the rail support until the catch engages in the locking well, pushing the button upwardly to engage a hole defined by the top lid. The top lid is then locked, in the open position and the internal cavity within the canister is exposed, thereby providing access to the looped, distal end of the mooring line inside. The looped end is pulled out of the canister, causing the auto-retracting reel to unwind a desired length of the mooring line, and then the line is locked in place by pushing the button down to disengage the catch. This arrangement allows the springs to pull the underside of the top lid so that it is biased toward a closed position. The mooring line is then locked into position as the mooring line is pinched between the spring-loaded top lid and the internal side of the canister and rail support. 
     To return to the starting position, the user unties the mooring line from the dock cleat or other attachment means and simply re-opens the top lid, thus causing the mooring line to automatically retract back into the canister and wind up back onto the reel until the stopping collar prevents the looped end of the mooring line from retracting any further. Once the mooring line has been fully retracted so that the looped end is disposed within the canister, the top lid is then slid closed for storage and transport purposes.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention includes, in a first embodiment, a retractable mooring line assembly storing and dispensing line used to moor a boat  10 , and includes a user interface  12  having a canister  14  with a top lid  16  and a bottom lid  18 , an auto-retracting reel assembly  20  which windably stores mooring line  22 , and optionally, a conduit  24  that connects the reel assembly  20  to the user interface  12 . Between the top lid  16  and canister  14  is the rail support  26 . The top lid  16  slides along the parallel rails that are horizontally disposed on a top portion of the rail support  26  to open and close the canister  14 . The mooring line  22  feeds from the reel assembly  20  upwardly through a hole defined by the bottom lid  18 , and into the canister  14 . The looped end  28  of the mooring line  22  is stored in the canister  14  until ready for use. 
     The rail support  26  is a generally circular collar that is disposed on a top portion of the canister  14 , and includes a pair of parallel horizontal rails  54  for engaging a pair of grooves  56  on the underside of the top lid  16  so that the top lid  16  may slide horizontally between an open and closed position. The rail support  26  defines a centrally disposed hole  58  that the mooring line  22  passes through, and further includes a catch  30  and lid springs  34  which allow for the mooring line  22  to be locked into the desired position. The top lid  16  further includes a button  32  which is used in connection with the catch  30  and lid springs  34  to lock the mooring line  22  into the desired position. A spring  64  is positioned underneath the catch  30  such that when the catch  30  is engaged and the button  32  is not pressed down, the spring  64  is disengaged and potential energy is stored. When the catch  30  is disengaged and the button  32  is pressed down, the spring  64  is engaged in order to lock the mooring line  22  into the desired position. 
     The top portion of the canister  14  may include a threaded collar  62  to allow for attachment to a boat. At the bottom of the canister  14  a locking nut  36  and a stopping collar  38  are provided, and include a portal  60  through which the mooring line  22  may pass. The locking nut  36  and stopping collar  38  are preferably placed between the canister  14  and the bottom lid  18 , as shown in  FIG. 3 . The top lid  16  opens by sliding horizontally along the rail support  26  until the catch  30  engages in order to maintain the top lid  16  in the open locking position, which causes the button  32  to be pushed upwardly while the top lid  16  is locked into the open position, as shown in  FIG. 6 . When the top lid  16  is open, the canister  14  is exposed and the looped end  28  of the mooring line  22  is visible and accessible to a user. The mooring line  22  may be pulled outwardly from the canister  14 , unwinding from the auto-retracting reel assembly  20  for securing the vessel to a dock, pier, another boat, or the like. To lock the extended mooring line  22  into desired position so that the mooring line  22  does not retract back onto the auto retracting reel assembly  20 , the button  32  is pressed down to disengage the catch  30 , which allows the lid springs  34  to pull the top lid  16  toward a closed position. The top lid  16  may include an indentation having locking teeth  40 , as shown in  FIGS. 2 and 3 . These locking teeth  40  press against the mooring line  22  in combination with the force of the springs  34  to pinch the mooring line  22  securely into a desired position (or length), so that the mooring line  22  is pinched between the locking teeth  40  of the top lid  16  and the inner edge of the hole defined by the rail support  26 . To unlock the mooring line  22  from this locked position and release the mooring line  22  so that it may be retracted back to its original storage location on the auto-retracting reel assembly  20 , the top lid  16  is opened and the mooring line  22  is removed from the dock cleat or other securing mechanism on the dock, pier, or the like. The mooring line  22  automatically retracts until the stopping collar  38  prevents the looped end  28  of the mooring line  22  from passing therethrough. The mooring line  22  is wound onto the reel assembly  20  and the looped end  28  of the mooring line  22  is disposed within the canister  14  when not in use, preferably with the top lid  16  in a closed position. It should to be understood that any type of stopping mechanism may be used to prevent the looped end  28  of the mooring line  22  from pulling through the bottom portion of the canister  14 . Additionally, any suitable locking mechanism may be used to prevent the mooring line  22  from retracting back onto the auto-retracting reel assembly  20 , including clamps, mechanical stops that engage gears, or any other suitable locking mechanism. 
     The auto-retracting reel assembly  20 , in one embodiment, includes a spool  42 , a base  44  with a free end  46  and a spring end  48 , and a spring  50 . The spring  50  is a flat rolled steel coil spring that provides the storage for the energy required to spin the reel assembly  20  and retract the mooring line  22 . When the mooring line  22  is extended, the spring  50  winds up more tightly, causing the spool  42  to be biased toward a wound position. The spool  42  sits inside of the base  44  wherein one end of the spool  42  attaches to the spring end  48  and the other end of the spool  42  attaches to the free end  46 . The spool  42  rotates along the horizontal axis  52  in order to extend and retract the mooring line  22 . It should be understood that the auto-retracting reel assembly  20  may take any form that is suitable for retracting a boat mooring line, and such auto-retracting reel assemblies are commercially available in various forms with different types of assemblies and components. 
     In a preferred embodiment, the user interface  12  is installed on the outside or gunwale of the boat near where a cleat would be placed for tying an external rope, and the auto-retracting reel assembly  20  is installed in a hidden place such as the inside of the boat near the wall of the boat. In an alternate embodiment, the retractable mooring to line assembly  10  may be mounted onto a dock, pier, or the like, so that the mooring line  22  may be extended therefrom and secured to a boat, rather than extending from the boat to the dock. The auto-retracting reel assembly  20  may also include a locking mechanism for locking the spool  42  in place. An example of a suitable locking mechanism can be seen in U.S. Pat. No. 9,694,878, which is incorporated herein by reference (see  FIG. 12 , Elements  16 ,  62  and  64 ). This arrangement is particularly useful when the mooring line  22  needs to be replaced. To replace an old line on the spool  42 , a user can pull the mooring line  22  until most of the line has been disengaged from the spool, lock the spool in place using the locking mechanism, replace the mooring line  22 , and then release the locking mechanism for auto-retraction. It should be noted that while the locking mechanism cited above is a suitable locking mechanism for incorporation into this retractable mooring line assembly, other types of locking mechanisms may be used, instead, and such locking mechanisms are well known in the art. 
     The conduit  24  connects the auto-retracting reel assembly  20  to the user interface  12  and functions as a channel for the mooring line  22  to pass through unobstructed between the reel assembly  20  and the user interface  12 . 
     Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein. All features disclosed in this specification may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
