This invention relates to an apparatus for releasably coupling and decoupling clips 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 cleat or a mooring buoy. The mooring line is tied around the dock cleat 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 neglects 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. 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 the hook is retained 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 which are generally considered the easiest to operate are those employing a long rod which acts as an extension of the boater's arm and then has a clip located on each end wherein the opening and closing of the clips by remote means eases the burden of the procedure.
The present invention overcomes the problems outlined above and provides safe and convenient clips for docking a boat to a mooring structure with the aid of a mooring pendant apparatus. The apparatus releasably couples or decouples to an eyelet on the bow of the boat or to a buoy. The apparatus includes a pair of clips, one on each end of an elongated rod, wherein the clips open and close for attachment or release. The clips each comprise integral hook and ring sections which define a mouth therebetween. Each hook section includes an attachment hook which attaches to a movable arm having an upper bridge section, wherein means are provided to force the movable arm into the attachmet hook and therein exert a tension on the bridge section to keep the clip biasly in a closed position.
One embodiment teaches that both ring sections include an access of rotation hole to provide an anchoring position for a functional retractor lever. Levers include a pair of right and left lower and upper arm sections, the lower and upper arms forming a variable angular deviation in relationship to each other. The retractor levers each include a functional contact section for engaging a movable arm into an open or shut position and a variable curved lever arm having at a distal end an extension piece that is frictionally fitted with great bias into an axis of rotation hole, therein creating the torque for the retractor lever to operate. The movable arm of each clip has an upper bridge section that is snap-locked into the hook section to close the mouth. The movable arm is placed under tension by the stress created in geometric positioning of a pair of leg sections. A long leg section extends downwardly and at a distal end fits an insertion piece into a lower opening in the ring section and a shorter leg section also having an insertion piece that fits into an upper opening in the ring section. This leg design produces a torque on the movable arm urging it to be biased in a closed position.
The invention uses a pair of cables, a first cable attached to the first retractor lever and a second cable attached to the second retractor lever for activation of the clips. These cables first pass through a fixed handle that keeps them aligned for use, and then each cable is secured to an opposite end of a single sliding handle, wherein a boater may pull on the sliding handle with sufficient force to overcome either of the locking tensions placed on the movable arm.
An embodiment of the invention utilizes a method for placing the movable arm under tension, wherein an internal spring is located in a movable arm to exert the tension necessary to lock the arm into the hook of the clip. This embodiment employs both a left and right arm having an angular deviation. The arms formed in a bowed position in relationship to each other, and the pull on the movable arm is on both sides of the arm.
While many other materials may be used, the clips, and the rods 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 clips by welding. While many materials may be used to withstand the harsh conditions and weather, the cable is preferably formed from aircraft cable or polyvinyl-chloride coated steel.
Several embodiments of clips have been discussed, and it is to be appreciated that various combinations of clips may be utilized.

Preferred embodiments of the invention will now be described with reference to the Figures. Some terms used in the description and the appended claims are defined below.
Referring to
The present invention uses one of the more common commercially available clips and then alters that clip in a most novel manner. As best illustrated in
The movable arms 44a, 44b have long leg sections 69a, 69b extending in a downwardly direction and at distal ends, insertion pieces 68a, 68b which frictionally fit with great bias into a lower openings 70a, 70b respectively, and also the movable arms have shorter second legs 71a, 71b having an insertion pieces 72a, 72b which friction fit into upper openings 74a, 74b. The design of the movable arms 44a, 44b is such that they have a bend. Such a design allows for the movable arms to be placed under tension resulting in a natural state of closure. The clips of the invention utilize carefully engineered locations for holes on the ring structure. The site for the access of rotation holes 46a, 46b were carefully chosen to insure that the clips would not be weakened structurally. The design of the movable arms 44a, 44b and the manner they are bent is part of the inventive concept. Such a design allows for the movable arm to be placed under tension resulting in a natural state of closure. As previously stated, it is preferred that the clip be manufactured for a solid piece of stainless steel, however brass or some other corrosion resistant material may be utilized without compromising the inventive concept.
A first end 25 of the elongated rod 24 is integrally attached to the first ring 38a as art of a cast, welded, forged, or combination thereof. The rod 24 extends through both the first fixed handle 28a, then through the sliding handle 30, and finally through the second fixed handle 28b wherein a second end 27 of the rod 24 is attached to the second clip 22b. The first or second clips 22a, 22b may be used to tie a mooring rope/line. As best seen on
The mooring line referred to above is usually a strong and sturdy rope. When the mooring pendant apparatus 20 is kept in the boat, the connectivity is usually made to one of the clips 22a, 22b connecting to the mooring line either through a clip on the line or a loop on the line, and then the boater proceeds to secure the boat by connecting the apparatus to the bow ring utilizing the opposite clip on the apparatus 20. While one of the mooring lines is utilized by the apparatus, the second mooring line is usually connected to one or more of the cleats on the boat. 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, reaching and securing the line to the bow ring is made slightly easier, provided that the apparatus is kept within a reasonable length and weight.
In any discussion of the clips 22a and 22b, if only one of the clips is mentioned, the discussion will apply to both clips as they are mirror images of each other. As described already, the movable arms 44a, 44b are the active part of the clips, as this is where the tension is created as a result of the design of the length of the long legs 69a, 69b, and short legs 71a, 71b and their positioning that keep the movable arm biased in the closed position. This is the functional component of the clips, since by pulling on either of the cables 26a, 26b, through the intermedium of the designed functional retractor lever, the mouths of the respective clips open, and by releasing the cables, the mouths close.
The elongated 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 28a, 28b, and sliding 30, require a channel 80 to be of a size and shape to accommodate the rod 24. When a circular cross-sectional rod is used there may be a tendency for the sliding handle to rotate on the rod. The location of the fixed handles may aid in limiting the rotation of the sliding handle. The rotation of the sliding can also be limited by a preferred embodiment utilizing a hexagonal or oval shaped rod as well as a rod with controlled curvatures in key locations.
The retractor arm 48a forms part of a unique design of the present invention. As previously cited, it has two arm sections, a lower arm section 54a and an upper arm section 56a which are bent in relationship to each other, therefore forming an angular deviation which may be variable. The bending of the retractor arm 48a lowers it in such a manner that it is in closer proximity to the rod 24, and the design of the angular deviation is a factor in the exertion necessary for the pull cable 26a. The contact section 58a of the retractor arm 48a maintains direct contact with the movable arm 44a. This provides the functional aspect of the invention, such that when the cable 26a 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 sliding handle 30, the cable tension is also lessened hereby closing the clip 22a. It is shown on
The cables 26a, 26b 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 arms open and close, as the distance of the sliding handle pull is essentially measured. As stated both cable 26a, 26b have one end attached to the looped section of the retractor arms 48a, 48b and are secured with a ferrule clip 76a, 76b. The cables freely move through the beveled conduits 78a and 78b, without hindrance or resistance, and connect to the sliding handle 30, wherein they are secured internally. In the present invention, the fixed handles 28a and 28b are firmly connected to the rod 24 and the sliding handle 30 is positioned at a certain distance above the fixed handle but not secured firmly to the rod 24. The distance between the fixed handle and the sliding handle is established by how much the sliding handle 30 has to be pulled towards the fixed handles 28a, 26b to completely open the mouth of the clip. Therefore, it is critical that the cable maintain its length with no elongation allowed.
As shown in
As described already, the movable arms 44a, 44b are the active parts of the clips 22a, 22b, as this is where the tension is created as a result of the functional retractor levers 48a, 48b. This is the functional component of the clips, since by pulling either of the cables 26a, 26b, the corresponding clips open, and by releasing the cables, the corresponding clips close. As described, the present invention discusses the activation of only one clip at a time, meaning that when the first clip 22a is being activated by pulling on cable 26a, the sliding handle 30 may slide the length between it and the second fixed handle 28b and vice versa when the second cable 26b is pulled. Both cables 26a and 26b are secured in the conduits 78a and 78b of the sliding handle 30. Even though the present apparatus discusses the one clip activation, with minor variation of the sliding handle 30 one can achieve the activation of the two clips at a time. This variation involves severing the sliding handle in half such as that it resembles two fixed handles. The pull cable will terminate in each of the segmented components and instead of being one sliding handle, it will be two sliding handles with a separation between them which will allow the user to unite the two sliding handles into one by pulling them towards each other and thereby completing the length of the original sliding handle. This action will allow both clips to be opened at the same time with the user holding one hand on the joined components of the sliding handle.
An alternate clip embodiment is presented on
The clip 120 as shown in
A leg section 168 extends in a downwardly direction and has at a distal end an extension piece 162 that frictionally fits with great bias into the axis of rotation hole 146, therein creating a leveraging anchor for the retractor lever 148. The movable arm 144 of the apparatus has an upper bridge section 164 which snap-fits into the attachment hook 166 on the hook section of the clip 122 to close it. An internal spring 149 creates the necessary tension to biasly hold the movable arm 144 in the closed position. The location for the access of rotation hole 146 was selected on the ring section 138 at a site as to not alter the clip's ability to function or weaken it. The site herein was chosen to allow insertion of the extension piece 162 which as previously stated creates an axis of rotation for the retractor lever 148. Since the movable arm 144 of the clip has an internal spring 149 located within it, holes could not be placed within its' length. If such were done, then the clip could very well be destroyed and de-activated. When activated by pulling on the cable 26, the curved functional contact section 158 engages the movable arm 144, therein causing it to rotate inwards and thus opening the clip. By curving the functional contact section 158 the lower edge is placed in contact with the movable arm 144 and there is less chance of it coming too close to the end of the movable arm. The functional contact section 158 could also be straight rather than curved but curved is preferred thereby allowing the contact section 158 to go lower.
The functional aspect of the invention, wherein when the cable 126 is pulled, it exerts a rotational force about the access of rotation hole 146, thereby applying pressure on the movable arm 144 releasing it from the hook 166 and thus opening-up. The reverse of this action is such that upon releasing the pull on the movable handle 130, the cable tension is lessened thereby closing the clip 122. It is shown on
While it is apparent that the illustrative embodiments of the invention herein disclosed fulfill the objectives stated above, it will be appreciated that numerous modifications and other embodiments may be devised by those skilled in the art. Therefore, it will be understood that the appended claims are intended to cover all such modifications and embodiments which come within the spirit and scope of the present invention.
