1. Field of the Invention
This invention relates to a method and apparatus for controlling a rope, as to facilitate drawing of a boat towards a docking space.
2. Background Art
Recreational boaters and those in the shipping industry are commonly faced with the problem of drawing a boat/ship (hereinafter “a boat”) towards a docking space with the boat in relatively close proximity thereto.
Typically, boats are able to maneuver under their own power, or be pushed by a tugboat, to a position adjacent to a dock at which the boat will ultimately be secured. The most challenging aspect of docking occurs typically when the boat is required to be secured along a dock at a mooring that runs parallel to the boat length and has a length equal to, or only slightly greater than, that of the boat. This maneuver can be compared to parallel parking a car.
Commonly, the boat will be preliminarily situated with its length parallel to the length of the mooring, whereupon hooks and/or ropes are used to draw the boat in a sideways direction to against the dock. Typically at such docks, there are a series of cleats that cantilever upwardly and accept a rope that can be tied therearound.
The recreational boater may often have the assistance of someone on the boat as well as someone on the dock as the docking operation is performed. Commonly, long ropes will be thrown from the boat to an assistant who is then able to pull on the rope to reposition the boat.
More commonly, however, the recreational boater will be in a situation wherein he/she will be without any assistance from the dock. The boater is thus faced with the task of laterally repositioning the boat from a position within the boat that is spaced from dock. This procedure is normally attempted in one of two different ways.
The boater may have one or more ropes with a pre-formed, restrictable lasso which the boater may toss towards the dock cleat in an attempt to surround the same with the loop defined by the lasso. If successful, the boater may then pull upon the rope to draw the boat to against the dock.
This procedure requires a certain amount of skill in throwing the rope. Inevitably, several efforts may be unsuccessful. If the lasso has a restrictable loop, each time the failed attempt is completed, the boater may be required to re-enlarge the loop preparatory to a subsequent effort.
While in calm conditions, this trial and error effort may not have significant consequences other than being an inconvenience, in rough conditions, the delay in securing the rope may permit winds or wake to reposition the boat either away from the dock or dangerously towards another structure or boat.
Alternatively, boat hooks are used. Typically such a boat hook will have an elongate pole with a hook at a distal end thereof. The boater manipulates the proximal end of the pole to engage the hook on some type of structure at the dock and then draws the boat towards the dock by exerting a pulling force on the proximal end of the pole.
While use of boat hooks may be preferred by reason of being able to more reliably engage the dock therewith, boat hooks have some inherent drawbacks. First of all, the docking process typically involves two distinct steps when a boat hook is employed. That is, the hook is manipulated to draw the boat towards the dock, whereupon a separate rope must be secured between the boat and a cleat, or other structure, on the dock. In calm conditions, this two-step process may be moderately inconvenient. In rough conditions with a single boater performing the docking operation, it may be awkward to serially perform the steps without losing some control over the position of the boat.
Additionally, with large or heavy boats, the capacity of the boat hook must be substantial or alternatively there is a risk of the same failing during use.
The industry has developed a number of rope control mechanisms wherein a looped rope can be maneuvered to place the loop around a cantilevered object, such as a cleat. Exemplary structures are shown in U.S. Pat. Nos. 2,811,127 (Palsson); 3,677,597 (Stipek); 3,841,685 (Kolodziej); 3,918,385 (Wallace); 4,667,617 (Molitor); 5,009,181 (Upchurch); 5,116,260 (Upchurch); and 5,799,602 (Trillo). Generally, these structures are less than optimal by reason of their being either complicated in nature or less than convenient to use.
Ideally, a boater would have a lightweight structure that is both simple and reliable to use, whereby a lone individual on a boat might be able to readily, conveniently, and safely complete the docking of a boat.
In one form, the invention is directed to a method of directing a rope around a cantilevered support. The method includes the steps of a) providing an apparatus for controlling the rope having i) an elongate pole with a length and a proximal region and a distal region spaced from each other in a lengthwise direction, and ii) a rope engaging assembly at the distal region of the elongate pole, the rope engaging assembly having at least one surface facing generally in a lengthwise direction away from the proximal region; b) configuring the rope so that the rope bears against the at least one surface and a portion thereof is thereby formed to be generally U-shaped opening towards the proximal region with the rope in an operative position on the apparatus; c) holding at least a second portion of the rope and the elongate pole at the proximal region so that the rope is borne against the at least one surface to maintain the U-shaped rope portion in the “U” shape; and d) manipulating the elongate pole with the rope in the operative position to cause the U-shaped portion of the rope to be directed around the cantilevered support.
In one form, the method includes the step of exerting a force on the rope at a first location spaced from the U-shaped portion to tension the rope between the cantilevered support and the first location.
In one form, the rope engaging assembly consists of two discrete surfaces that are spaced transversely from each other with respect to the length of the pole.
In one form, the rope engaging assembly has a U-shaped body that opens away from the proximal region of the pole. The body has a base and spaced first and second legs that terminate at first and second free ends. The two discrete surfaces are located one each at the first and second free ends.
One discrete surface may be defined by a first fitting having a first surface bounding a first U-shaped receptacle. The first surface has a base portion and first and second spaced leg portions that cooperatively define a “U” shape. The base portion defines the one discrete surface.
In one form, the pole has a lengthwise central axis and the first U-shaped receptacle opens in a line that is non-parallel to the central axis of the pole.
In one form, the other discrete surface is defined by a second fitting having a second surface bounding a second U-shaped receptacle. The second surface has a base portion and first and second leg portions that cooperatively define a “U” shape. The base portion on the second fitting defines the other of the two discrete surfaces.
In one form, the first U-shaped receptacle opens in a first line and the second U-shaped receptacle opens in a second line. The first and second lines define a “V” shape through which the central lengthwise axis of the elongate pole extends.
In one form, the central lengthwise axis substantially bisects the “V” shape.
The first surface may be made from a material that resists sliding movement of the rope thereagainst.
In one form, with the rope in the operative position, the rope is releasably frictionally held between the first and second leg portions on the first fitting.
In one form, the step of holding at least a second portion of the rope comprises holding at least a second portion of the rope from a floating vessel that is spaced from the cantilevered support. The step of exerting a force on the rope involves exerting a force on the rope to thereby cause the floating vessel to be moved towards the cantilevered support.
In one form, the method further includes the step of securing the rope at the cantilevered support to thereby maintain a desired relationship between the floating vessel and the cantilevered support.
In one form, the method includes the step of separating the apparatus from the rope by translating the apparatus away from the U-shaped portion of the rope by movement of the apparatus relative to the rope in a direction in which the U-shaped portion of the rope opens.
In one form, the step of configuring the rope involves configuring the rope into a loop to define the U-shaped portion.
In one form, the step of configuring the rope involves configuring the rope into a loop with a restrictable diameter and the step of exerting a force on the rope involves exerting a force on the rope to tension the rope and thereby reduce the diameter of the loop.
In one form, the elongate pole and a first rope engaging assembly are independent components that are releasably connected together.
In one form, the method further includes the step of providing a second rope engaging assembly that has a different configuration than the first rope engaging assembly and the first and second rope engaging assemblies are selectively connectable to the elongate pole, one in place of the other, thereby to choose a desired configuration for the apparatus.
In one form, the invention is directed to the combination of an apparatus for controlling a rope and a rope that is in an operative position on the apparatus. The apparatus has: i) an elongate pole with a length and proximal and distal regions spaced in a lengthwise direction; and ii) a rope engaging assembly at the distal region of the elongate pole. The rope engaging assembly has at least one surface facing generally in a lengthwise direction away from the proximal region. The rope in the operative position is configured to bear against the at least one surface so that a portion of the rope is U-shaped opening towards the proximal region with at least a second portion of the rope extending towards the proximal region of the pole so that a force can be exerted on the at least second portion of the rope to maintain the portion of the rope that bears against the at least one surface U-shaped. The rope engaging assembly is configured so that the rope can be selectively placed into the operative position and separated from the rope engaging assembly by relatively translating the rope and rope engaging assembly.
In one form, the rope engaging assembly has two discrete surfaces that are spaced transversely from each other with respect to the length of the pole.
In one form, the rope engaging assembly has a U-shaped body that opens away from the proximal region of the pole. The body has a base and spaced first and second legs that terminate at first and second free ends. One of the two discrete surfaces is located at each of the first and second free ends.
In one form, one discrete surface is defined by a first fitting having a first surface bounding a first U-shaped receptacle. The first surface has a base portion and first and second spaced leg portions that cooperatively define a “U” shape. The base portion defines the one discrete surface.
In one form, the pole has a lengthwise central axis and the first U-shaped receptacle opens in a line that is non-parallel to the central axis of the pole.
In one form, the other discrete surface is defined by a second fitting having a second surface bounding a second U-shaped receptacle. The second surface has a base portion and first and second leg portions that cooperatively define a “U” shape. The base portion on the second fitting defines the other of the two discrete surfaces.
In one form, the first U-shaped receptacle opens in a first line and the second U-shaped receptacle opens in a second line. The first and second lines define a “V” shape through which the central lengthwise axis of the elongate pole extends.
In one form, the central lengthwise axis substantially bisects the “V” shape.
In one form, the first surface is made from a material that resists sliding movement of the rope thereagainst.
In one form, with the rope in the operative position, the rope is releasably frictionally held between the first and second leg portions on the first fitting.
As seen in
The apparatus 10 is particularly adaptable for use in one particular environment, as shown schematically in
One more specific depiction of the environment in
One preferred form of the apparatus 10, and its interaction with the rope 12, is shown in
The proximal end 28 has a grip 32 around which a user's hand can be extended to comfortably grasp and manipulate the elongate pole 24. Other types of structure might be used, such as a closed loop, etc.
A free end 34 at the distal region 30 of the pole 24 is designed to telescopingly engage a stub shaft 36 on a rope engaging assembly 38. With the stub shaft 36 and pole end 34 telescopingly engaged, one within the other, openings 40, 42, respectively in the pole 24 and rope engaging assembly 38, register to allow direction therethrough of a bolt or a pin (not shown). The invention contemplates that any type of mechanism, shown schematically at 44 in
For example, the mechanism 44 may be a detent arrangement which allows a user to depress a spring-loaded component to effect release of the connection between the pole 24 and rope engaging assembly 38.
The rope engaging assembly 38 has a U-shaped body 46 with a base 48 and first and second legs 50, 52, extending from the base 48 in a manner that the base 48 and legs 50, 52 cooperatively define the “U” shape. The first leg 50 has a first free end 54 at which a first fitting 56 is provided. The second leg 52 has a second free end 58 at which a second fitting 60 is provided. The first and second fittings 56, 60 may be identical or may have a different configuration. In the embodiment shown, the fittings 56, 60 are the same and are mounted on their respective legs 50, 52 so as to be turned 180° with respect to each other about axes parallel to the central axis 26 of the pole 24.
The exemplary fitting 56 has a body 62 with a first surface 64 bounding a U-shaped receptacle 66. The receptacle 66 is bounded by a base surface portion (surface) 68 and first and second leg surface portions 70, 72, respectively.
The second fitting 60 has a receptacle 66′ bounded by a base surface 68′, corresponding to the base surface 68 on the first fitting 56.
The two discrete surface 68, 68′ extend generally along lines L1, L2, respectively, that make a V-shape with respect to each other. The axis 26 of the pole 24 extends through the “V” and preferably bisects the same.
The receptacle 66 on the first fitting 56, and the corresponding receptacle 66′ on the second fitting 60, open away from the proximal region 28 of the pole 24 and allow the rope 12 to be placed in an operative position upon the apparatus 10, as shown in
With the rope 12 and apparatus 10 in the configuration shown in
In the embodiment shown, the configuration of the rope engaging assembly 38 is such that it can be moved by simple translational movement in the direction of the arrow 86 in
By maintaining a slight tension on the second portion 80 of the rope 12 in the direction of the arrow 88, the rope 12 can be maintained within the receptacles 66, 66′ to maintain the “U” shape of the rope portion 76 as the apparatus 10 is manipulated as described above to place the loop 76 around the support 14.
The rope 12 can also be maintained within the exemplary receptacle 66 in
Accordingly, as shown schematically in
As an alternative to using a restrictable loop, as shown in
Once the vessel 16 is in the desired position, the rope 12 can be secured to the support 14 and vessel 16, as desired. Alternatively, another rope or holding mechanism may be used to accomplish this. This step is shown at block 108 in
With the embodiment in
The invention contemplates numerous variations from the basic structures described above. For example, the entire apparatus 10 can be made as one piece as opposed to having separate components, in this case the joinable pole 24 and rope engaging assembly 38.
The depicted configuration of the body 46 on the rope engaging assembly 38 is not in any way intended to be limiting. All that is required with this design is that there be two spaced, discrete surfaces 68, 68′ that can be bridged by the rope 12 to define the U-shaped portion 76 that can be directed around the support 14 as the apparatus 10 is operated. As just an example, the “U” shape of the body 46 may be off center with respect to the axis 26 of the pole 24, and potentially fully offset therefrom.
Further, the shape of the discrete surfaces 68, 68′ is not critical to the present invention. The function of the surfaces 68, 68′ could be performed by, for example, sharp pins, the ends of which would be considered “surfaces”, as used herein.
The spacing of the surfaces 68, 68′ can be changed depending upon the particular application and the nature of the support 14.
As a further alternative, as shown in
The apparatus 10 may be made from any of a number of different materials, such as metal, plastic, or a composite. The fittings 56, 60 could be integrally formed with the remainder of the body 48. They are shown as separate elements in this design in that this facilitates separate formation of the fittings 56, 60 with a material that has frictional properties that are more preferred than those of the material making up the rest of the body 46. For example, the fittings 56, 60 could be molded from a plastic material. The plastic material may flex to accept a larger diameter rope that may be squeezed therein. Additionally, the plastic may be treated so that its frictional characteristics are appropriate to avoid unwanted slippage between the rope 12 and fittings 56, 60.
With the structure shown, the U-shaped rope portion 12 can be resituated while being relatively firmly maintained in the “U” shape. The user is thus not faced with the problem that the loop will close as the apparatus is moved. This facilitates alignment of the loop 74 with a support and direction of the loop 74 therearound.
The foregoing disclosure of specific embodiments is intended to be illustrative of the broad concepts comprehended by the invention.
