This invention relates to an apparatus for releasably coupling and decoupling a clip as to facilitate mooring a boat. More specifically, the apparatus allows for easier attachment of a mooring line to the bow of a boat.
Pleasure boats, such as yachts and small boats, are often moored to either a dock rail or a mooring buoy. The mooring line is tied around the dock rail or through a mooring ring on a buoy. Preferably the mooring line is tied to a ring or eye member that is found on the bow of the boat. Because of the difficulty in securing a mooring rope to a relatively remote eye member, such as one found on the bow of a boat, the boater often omits this procedure and only ties the boat to the cleats on the top surface of the boat. The difficulty created in trying to tie the rope to the buoy ring may be just as hard because the boater must reach down for the buoy and then often must pull it up to tie the line. If the mooring line cannot be pulled up, due to factors such as weight or tension in its anchor line, a second person is usually required. The problem encountered in trying to tie a mooring rope to the ring on the bow of a boat is usually due to the awkward position in which most bow rings are located. Reaching over and trying to reach the bow ring may be very hazardous to a boater, especially in rough waters. An unassisted boater may even find it impossible to moor his boat. It may be especially difficult to attach and detach a tie line to a mooring buoy or a boat bow ring or eyelet, in situations where a boat is not small enough to permit the user to reach down and manually fasten or unfasten the clip which secures the tie line to the mooring buoy or bow ring. Also, tying the mooring line to cleats on the deck of the boat creates chafe which can weaken and eventually cause failure of the mooring line. And, with more boats being built with pop-up or pull-up cleats there is the problem of failure from the constant stress of the mooring line. When the freeboard is large, the boatsman must use a long boat hook or gaff to reach down and snag the mooring line and lift it up to height where he can manually snap or unsnap the clip from the buoy or bow eye member.
Remote control attachment assemblies are commercially available and such assemblies usually comprise a slide member designed to be attached to a conventional elongated boat hook and then retain the hook in an open position. This enables the open hook to engage the eye member of the mooring buoy or bow ring. Such assemblies are often difficult to use. The present invention has found that the type of devices that are generally considered the easiest to operate are those that employ a long rod which may be employed as an extension of the boater's arm and wherein the opening and closing of the clip by a remote means eases the burden of the procedure.
The present invention overcomes the problems outlined above and provides a safe and convenient clip for docking a boat to a mooring structure with the aid of a pendant mooring apparatus. The apparatus releasably couples or decouples to an eyelet on the bow of the boat or to a buoy. The apparatus includes a clip that may open and close for attachment or release. The clip is formed from a hook and an integral ring section which form an opening or mouth therebetween. There are three holes defined on the perimeter of the ring which also has an open portion in the center. The holes include first and second loaded holes and a movable arm having extended legs that friction fit into the loaded holes by such design and location that the movable arm is biased into a closing position on the clip. There is also an access of rotation hole in the ring section which coordinates with a functional retractor arm to activate the opening and closing of the mouth. The retractor arm includes lower and upper arm sections forming an angular deviation in relationship to each other, and a lever arm that with bias frictionally fits into the access of rotation hole to maintain the retractor arm in a state of rotational torque. The retractor arm is in functional contact with the movable arm and upon activation of a greater force by the boater the mouth of the clip is opened.
An embodiment of the invention employs a central rod having means for connecting a first end to the ring section of the clip and a second end containing a displaced eyelet for fastening of a mooring line. A cable, which has one end attached to the retractor arm and an opposing end attached to a handle, will activate the apparatus upon being pulled such that the clip opens and then will close when the pull on the cable is eased.
One embodiment utilizes a cable guide that is affixed to the central rod for maintaining control and alignment of the cable. A fixed handle is usually used to create a grip for the user.
While many other materials may be used, the clip, central rod and displaced ring of the mooring pendant apparatus are preferably formed out of stainless steel or brass and also may be cast or forged. When not cast the rod is integrally connected to the clip by welding. The cable is preferably formed from aircraft cable in order to cope with the harsh conditions of water and weather. The displaced eyelet may be expanded to include multiple eyelets for attachment of multiple mooring ropes, and may be affixed to the mooring line or may be connected at the time of use, thus keeping it on board the boat as opposed to keeping it connected to the mooring line and mooring ball.

Preferred embodiments of the invention will now be described with reference to the Figures. Some terms used in such description and in the appended claims are defined below.
Referring to
The present invention alters one of the more common commercially available clips and employs it in a most novel manner. As best illustrated in
A first end 25 of the central rod 24 is permanently attached to the ring 38 by welding, or some other conventional fashion and the rod then extends in succession: through the cable guide 32, then the movable handle 30, and lastly through the fixed handle 28 to a place wherein a second end 27 attaches to a displaced eyelet 34. The eyelet having an opening 84 defined therein for tying a mooring rope/line 42. For securing and controlling the cable 26, a cable guide 32 is provided which is shown in
The mooring line 42 referred to above is usually a strong and sturdy rope. While the instant invention prefers the mooring line to be connected to the displaced eyelet 34, it can also be placed on the ring 38, although when placed on the ring 38 a tight fit is created making it rather difficult to control both the rope and the clip 22. The present invention envisions using the displaced eyelet 34 to affix the mooring line and yet still having the ability to consider the floating of the apparatus when it is not connected to the bow ring on the boat. If the mooring pendant apparatus 20 does not float, then it needs to be placed on or near the mooring ball rather than risk having it sink. When in use the mooring pendant apparatus 20 is connected to the bow ring and serves as an extension of the user's arm. When the mooring line and apparatus 20 are kept in the boat, the connectivity is usually made to the displaced ring 34 and then the boater connects the apparatus 20 to the bow ring. A second line is usually connected to one or more of the cleats on the boat and depending on the length of the central rod 24 the pendant apparatus 20 can be used to retrieve the mooring line 42. The length of the pendant apparatus 20 is a variable based on how much a boater can handle. Since it is an extension of one's arm it is very easy to reach and secure the line to the bow ring, providing it is kept to a reasonable weight.
As described already, the movable arm 44 is the active part of the clip 22, as this is where the tension is created as a result of the design of the length of the legs 69, 71 and their positioning that keep the movable arm biased in the closed position. This is the functional component of the clip, since by pulling the cable 26, the mouth of the clip 22 opens, and by releasing the cable 26, the mouth closes.
The ring 38 section of the clip 22 serves three functions. First, it can house the mooring line, although our preferred housing place as previously stated, is at the displaced eyelet 34 site, secondly because a specific location was chosen on the ring 38 to place an access of rotation hole 46 (the only location which will not possibly effect the integrity of the clip 22, i.e. does not weaken it). The size of the access hole 46 is a function of the size of the retractor arm 48 which is in turn determined by the size of the clip 22. The retractor arm 48 has a curved lever arm 60 with an extension piece 62 inserted into the access hole 46 with great bias. The open ring structure is maintained because it allows for connection to the mooring line, if so desired, and yet still be in contact with the retractor arm 48 for easy opening and closing. If the apparatus is cast, and the ring subsequently is filled solid, such that there is no central opening 40 in the ring 38 to tie the mooring rope, the inventive concept still exists as long as the ring shape was maintained. And thirdly, the importance of the ring structure is that when the remaining two holes on the ring, the lower hole 70 which accommodates the first insertion piece 68 from the distal end of the first leg 69 of the movable arm 44, and the upper hole 74 accommodating a second insertion piece 72 from the shorter second leg 71 of the movable arm, are coordinated and work as designed, a tension is created resulting in the bridge section 64 of the movable arm 44 locking within the hook 66 of the clip 22.
The present invention preferably has the mooring line 42 tied to the displaced eyelet 34. In this design the mooring line is thus displaced away from the clip 22 to avoid the tight spacing if it were tied to the ring 38 on the clip 22, and also so that it cannot interfere with the function of the movable arm 44 or retractor arm 48. This design also displaces the weight of the mooring line to an area further back, thus creating better leverage. While any geometric configuration for the ring may be used, such as a pear shaped design which could offer more room for the mooring line, or a large oval or large triangular form, the line angles must be round to avoid chafing the mooring line when in motion. As previously stated, the displaced eyelet 34 may have a plurality of rings at the end of the rod, therein allowing for more than one mooring line to be connected.
The central rod 24 serves as an extension of one's arm, and may be of any length or diameter or geometric configuration as well. The handles, fixed 28 and movable 30, require a channel 80 to be of a size and shape to accommodate the central rod 24. When a circular cross-sectional rod is used there may be a tendency for the movable handle to rotate on the rod. For this reason a preferred embodiment can have a hexagonal or oval shaped rod, and the rod may also have curvatures. The location of he cable guide 32 limits the rotation.
The cable 26 is maintained within a cable guide 32 that is illustrated in
The retractor arm 48 forms part of a unique design of the present invention. As previously cited, it has two arm sections, a lower arm section 54 and an upper arm section 56 which are bent in relationship to each other, therefore forming an angular deviation which may be variable. The bending of the retractor arm 48 lowers it such that it is in closer proximity to the rod 24, and the angular deviation is a factor in the exertion necessary for the pull cable 26. The contact section 58 of the retractor arm 48 maintains direct contact with the movable arm 44. This provides the functional aspect of the invention, such that when the cable 26 is pulled, it exerts a rotational force around the axis of rotation within the access hole 46 thereby applying pressure on the movable arm 44 by pulling it backwards to cause it to separate from the hook 66 and thereby open. The reverse of this action is such that upon releasing the pull on the movable handle 30, the cable tension is also lessened hereby closing the clip 22. It is shown on
The cable 26 can be made of any material having the strength and capability to handle salt water, controlled elongation under wet conditions, as well as the effects of warm or cold temperatures. Materials may include rope or aircraft cable, but any wire, cable or rope may be substituted provided it can cope with the harsh environment without any elongation problems. Aircraft cable is preferred for the present invention and it has shown excellent controlled elongation under wet conditions. If stainless steel is used, it is better if coated so that it is not be abrasive to the system or to the grasp of the user's hands. Lack of elongation is critical as any elongation of the cable would affect the distance in which the movable bar opens and closes, as the distance of the movable handle pull is essentially measured. As stated the cable 26 is attached to the looped section 50 of the retractor arm 48 and is secured with a ferrule clip 76. The cable 26 freely moves through the beveled conduit 78 of the cable guide 32, without hindrance or resistance, and connects to the movable handle 30, wherein it is secured internally. In the present invention, the fixed handle 28 is connected to the rod 24 and the movable handle 30 is positioned at a certain distance above the fixed handle but not secured to the rod 24. The distance between the fixed and movable handles is established by how much the movable handle 30 has to be pulled towards the fixed handle 28 for movable arm 44 to completely open the mouth of the clip. Therefore, it is critical that the cable maintain its length with no elongation allowed.
