The present invention relates to a fid suitable for splicing rope, and more particularly to a fid having a first and second channel and an aperture disposed through the channels to receive the rope being spliced.
Fids are used in many fields for splicing rope such as braided or covered rope. A fid is used to open up strands or portions of rope for splicing. In particular, the fid is used in holding rope open or can be used to allow a splicer to push strands through another section of rope as part of the splicing process.
Many fids are made from wood, bone, aluminum, steel, or plastic material. Conventional fids have a conical shape with a tapered end portion. A fid can be constructed to have a variety of diameters based on the size of the rope being spliced.
In one example, the fid is an aluminum bar with a tapered point front section on one end and a hollow back section at an opposite end with respect to the front section. The front section is used to open up strands of rope using the tapered point. Some of the strands of rope can be laid flat into the hollow back section of the fid so that the fid can be used to pull these strands through another section of rope. Some require a “pusher” to help retain a segment of rope, such as a core portion, and then push the fid through another segment of rope.
In addition to a fid being used in direct contact with the rope, some fids have markings along the fid's body that are used for measuring segments of rope at certain stages in the splicing process. In particular, a fid can be used as a measurement tool for determining points in the rope where actions need to be taken during the splicing process.
There has been a need for a fid capable of holding onto a segment of rope while the fid is threaded through another section of the rope. In one example, the segment of rope is taped onto a back end of the fid to keep it securely in place. Alternatively, fids having the hollow back section can provide a space for the segment of rope to be laid flat within during splicing. However, the hollow back section often requires further taping to secure the rope within the fid. Therefore, this issue has not been adequately addressed or solved.
There is a need for a fid that provides an improved feature of clutching or grasping a segment of rope to be threaded through another segment of rope during the splicing process without requiring additional taping, pushing, or auxiliary fasteners, which would slow down the splicing process. The present invention is directed toward further solutions to address this need, in addition to having other desirable characteristics.
In accordance with an embodiment of the present invention, a fid for splicing has an elongate body having a first end and a second end opposite the first end. The elongate body includes a transitional section between the first end and the second end. The first end terminates in a tapered point. The elongate body has a first section disposed between the first end and the transitional section. The first section includes a first effective cross-sectional area based on a first effective outer diameter. The elongate body has a second section disposed between the second end and the transitional section. The second section has a second effective cross-sectional area that is greater than the first effective cross-sectional area. The second effective cross-sectional area is defined by a second effective outer diameter. The elongate body has a first channel formed along a first side of the second section. The first channel extends from the second end toward the transitional section. The elongate body has a second channel formed along a second side of the second section. The second channel extends from the second end toward the transitional section. The second side is opposite the first side. The fid includes an aperture passing from the first side of the second section through to the second side. The aperture is disposed in both the first channel and the second channel.
In accordance with aspects of the present invention, the second effective cross-sectional area can be about 2 to 4 times greater than the first effective cross-sectional area. The second effective cross-sectional area can be sized and dimensioned in such a way that a segment of rope, determined by the particular form of splicing required, has a cross-sectional area that is less than about half of the second effective cross-sectional area.
In accordance with aspects of the present invention, the first channel and the second channel can be sized and dimensioned to receive a segment of rope, determined by the particular form of splicing required, in such a way that the segment of rope has a diameter that is about equal to or less than a depth of the first channel. The segment of rope can have a diameter that is about equal to or less than a depth of the second channel.
In accordance with aspects of the present invention, the elongate body can be made from a solid material. Alternatively, the elongate body can be made from a metal, wood, plastic, composite, or any combination thereof.
In accordance with aspects of the present invention, the aperture can have an elongate shape.
In accordance with aspects of the present invention, the fid can include a second aperture passing from the first side of the elongate body through to the second side. The second aperture, disposed proximal with the first end, can provide an insertion point for a tool in such a way that when the tool is inserted in the second aperture, a temporary handle is formed between the tool and the second aperture allowing a user to pull the fid through a rope.
In accordance with aspects of the present invention, the elongate body can be monolithic.
In accordance with aspects of the present invention, the first channel can extend through the second end and the second channel can extend through the second end.
In accordance with aspects of the present invention, the fid includes a rim portion surrounding the aperture to provide an edge configured to bite into a segment of rope and hold the segment of rope in place. In a further aspect, the rim portion can be a rounded edge section.
In accordance with an embodiment of the present invention, a method of using a fid for splicing includes providing a fid having a first channel formed along a first side of the fid and a second channel formed along a second side of the fid opposite from the first side. The fid includes an aperture passing completely therethrough and disposed in both the first channel and the second channel. A segment of rope is placed into the first channel. This segment of rope is determined by the particular form of splicing being implemented. An end of the segment of rope is threaded through the aperture to form a threaded segment of rope. The threaded segment of rope is folded in proximity of the aperture to form a folded segment of rope, thus enabling placement of the threaded segment of rope into the second channel. The threaded segment of rope is placed into the second channel.
In accordance with aspects of the present invention, the first channel and the second channel can be formed on a section of the fid having an effective cross-sectional area sized and dimensioned in such a way that the segment of rope has a cross-sectional area that is less than about half of the effective cross-sectional area.
In accordance with aspects of the present invention, the segment of rope can be a core portion of the rope. Using a fid, a section of the core portion of the rope is threaded through a section of a cover portion of the rope. The section of the core portion includes the segment of rope placed into the first channel, the threaded segment of rope, and the segment of rope placed into the second channel.
In accordance with aspects of the present invention, the segment of rope can be a cover portion of the rope. Using the fid, a section of the cover portion of the rope is threaded through a section of a core portion of the rope. The section of the cover portion includes the segment of rope placed into the first channel, the threaded segment of rope, and the segment of rope placed into the second channel.
In accordance with aspects of the present invention, the segment of rope can be a braided rope. Using the fid, a first section of the braided rope is threaded through a second section of the braided rope. The first section of the braided rope includes the segment of rope placed into the first channel, the threaded segment of rope, and the segment of rope placed into the second channel.
In accordance with aspects of the present invention, using the fid, a first section of rope can be threaded through a second section of rope. The first section of rope includes the segment of rope placed into the first channel, the threaded and folded segment of rope, and the segment of rope placed into the second channel. A frictional force experienced by the first section of rope placed into the first channel can be about equal to a frictional force experienced by the first section of rope placed into the second channel as the fid is pushed through the second section of rope.
These and other characteristics of the present invention will be more fully understood by reference to the following detailed description in conjunction with the attached drawings, in which:
An illustrative embodiment of the present invention relates to a fid having a first channel formed along one side of the fid and a second channel formed along an opposite side of the fid. An aperture passes completely through both the first channel and the second channel. This configuration enables the fid to grasp or clutch a segment of rope during the splicing process and hold it in place without the need for taping or additional fastening of the rope. More particularly, the segment of rope can be arranged within the first channel, second channel, and aperture, while substantially equal friction forces are experienced by the segment of rope in each channel, thereby holding the segment of rope in place as the fid is pushed through a second segment of rope. The segment of rope used is determined by the particular form of splicing that is implemented.
Referring now to
The fid 10 includes an elongate body 12 having a first end 14 and a second end 16 opposite the first end 14. In one example, the elongate body 12 is made from a solid material. For example, the elongate body 12 can be made from a metal material, wood material, plastic material, composite material, or any combination of these materials. In another example, the elongate body 12 is monolithic. The elongate body 12 has a length L as shown in
The elongate body 12 includes a transitional section 18 between the first end 14 and the second end 16. The transitional section 18 has a width that changes or tapers toward the first end 14 providing a transition between a first section 22 having width W1 and a second section 24 having a different width W2. The transitional section 18 tapers at an angle θ2 as shown in
The phrase “effective outer diameter” as utilized throughout the present description is intended to be utilized consistent with its ordinary and known usage. Specifically, the effective outer diameter is the measurement of the diameter of an imaginary flexible tube wrapped tightly around the object and not folded upon itself. For example, a tube wrapped around the letter “C” would follow the curvature of the letter on the top, bottom, and left sides, and then extend directly across the gap on the right side. The dimension of the diameter of the tube is the effective outer diameter.
Correspondingly, the phrase “effective cross-sectional area” as utilized throughout the present description is intended to be utilized consistent with its ordinary and known usage. Specifically, the effective cross-sectional area is the measurement of the total cross-sectional area that results from an imaginary flexible tube wrapped tightly around the object and not folded upon itself. For example, a tube wrapped around the letter “C” would follow the curvature of the letter on the top, bottom, and left sides, and then extend directly across the gap on the right side. The dimension of the cross-sectional area of the tube that results is the effective cross-sectional area.
The elongate body 12 includes the first section 22 disposed between the first end 14 and the transitional section 18. The first section 22 includes a first effective cross-sectional area based on the first effective outer diameter or width W1 as shown in
The first section 22 includes a tapered point 20 that terminates at the first end 14. The tapered point 20 has an angle θ1 as shown in
The elongate body 12 includes the second section 24 disposed between the second end 16 and the transitional section 18. The second section 24 includes a second effective cross-sectional area defined by a second effective outer diameter or width W2 as shown in
The second effective cross-sectional area is greater than the first effective cross-sectional area, as would be appreciated by those of skill in the art based on the relatively larger second effective outer diameter or width W2 relative to the first effective outer diameter or width W1 as described and shown. In one example, the second effective cross-sectional area is about 2 to 4 times greater than the first effective cross-sectional area. In another example, the second effective cross-sectional area is about 2.25 to 2.5 times greater than the first effective cross-sectional area. The second effective cross-sectional area is sized and dimensioned in such a way that a segment of rope 40, determined by the particular form of splicing required, has a cross-sectional area, that is less than about half of the second effective cross-sectional area as shown in
The elongate body 12 further includes a first channel 26 formed along one side of the second section 24. The first channel 26 extends from the second end 16 toward the transitional section 18. Also, the elongate body 12 has a second channel 28 formed along an opposite side, with respect to the first channel 26, of the second section 24. The second channel 28 extends from the second end 16 toward the transitional section 18. In one example, as shown in
The second section 24 has an aperture 30 passing completely through the second section 24 from one side to another. The aperture 30 is disposed in a portion of both the first channel 26 and the second channel 28. In one example, the aperture 30 has an elongate shape. As shown in
The first section 22 of the fid 10 includes a second aperture 32 disposed through the first section 22 near the tapered point 20. This second aperture 32 provides an insertion point for a tool so that when the tool is inserted into the second aperture 32 a temporary handle is formed between the tool and the second aperture 32. In one example, this allows a user to be able to pull the fid 10 through a thicker segment of rope 40 during the splicing process. For example, a nail, shaft, stiff wire, or another rope can be the tool inserted into the second aperture 32 to create the temporary handle for assisting in pulling fid 10 through a difficult segment of rope 40.
In
In one example, a first section of rope is threaded through a second section of rope. The first section of rope includes the segment of rope placed into the first channel 26, the threaded segment of rope in the aperture 30, and the segment of rope placed into the second channel 28. A frictional force experienced by the first section of rope in the first channel 26 is about equal to a frictional force experienced by the segment of rope placed in the second channel 28 as the fid 10 is pushed through the second section of rope. Said differently, when the segment of rope 40 is placed in the fid 10 and the fid 10 is being pushed/pulled through another segment of rope for example, any force or friction that can pull the segment of rope 40 out of the fid 10 is experienced equally between the segment of rope in the first channel 26 and the segment of rope in the second channel 28 such that it effectively cancels out any tendency for the segment of rope 40 to pull out of the fid 10.
The use of the fid 10 in accordance with the representations of
In accordance with one eye splice process example, the segment of rope 40 is a core portion of the rope. Using the fid 10, a section of the core portion of the rope is threaded through a section of a cover portion of the rope. The section of the core portion includes the segment of rope placed into the first channel 26, the threaded segment of rope in the aperture 30, and the segment of rope placed into the second channel 28. In another eye splice process example, the segment of rope 40 is a cover portion of the rope. Using the fid 10, a section of the cover portion of the rope is threaded through a section of a core portion of the rope. The section of the cover portion includes the segment of rope placed into the first channel 26, the threaded segment of rope in the aperture 30, and the segment of rope placed into the second channel 28.
In another example, the segment of rope 40 is a braided rope. Using the fid 10, a first section of the braided rope is threaded through a second section of the braided rope. The first section of the braided rope includes the segment of rope placed into the first channel 26, the threaded segment of rope in the aperture 30, and the segment of rope placed into the second channel 28. Many additional splicing processes may be implemented in conjunction with the present invention.
