Abstract
A device is presented that can be used as both a pad eye and as a fairlead independently and simultaneously while providing separation between the two modes of use. The device provides the option for multiple attachment points and multiple fairlead passages and reduces the need of requiring both a pad eye and additional hardware such as a pulley in applications such as the implementing of a jib sheet in-hauler system on a sailing vessel. Additionally, the device is configured in a symmetric manner so as to allow the device to be optionally joined and mated to a second but inverted such device allowing for the assembly of two such devices into a single combined unit. Such a combined configuration has the benefit of allowing for pad eye and fairlead functions to take place in a suspended location instead of being constrained to only a fixed surface.

DETAILED DESCRIPTION OF THE PRESENTED EMBODIMENTS
(20) FIG. 1A presents a perspective view of the first presented embodiment 130 of the device. The device consists of an annular ring 20 that has legs 22A and 22B protruding from the outside diameter 30 of annular ring 20. Annular ring 20 has both an outside diameter 30 and an inside diameter 28 and annular ring 20 is generally toroidal in shape. Annular ring 20 has a top side 24 facing in a direction defined as upward. Herein, directional terms such as upward, downward, outward, inward, top, bottom, vertical, horizontal and sides refer to the presented embodiment(s) in an exemplary orientation and are not intended to limit the device to any particular orientation. Conversely, ring 20 has a bottom side 26 facing a direction defined as downward. Legs 22A and 22B protrude outward radially from the outer diameter 30 of ring 20 and then curve and bend downward toward a fixed surface 36. Fixed surface 36 may be a boat deck or other surface. Bases 62 of legs 22A and 22B each have an underside surface 38. Underside surfaces 38 of the bases 62 of legs 22A and 22B are generally located coplanar to each other so that all underside surfaces 38 can sit evenly on surface 36. However, the positions of underside surfaces 38 of bases 62 of legs 22A and 22B can alternatively be offset vertically from each other depending upon the irregularity of fixed surface 36. Legs 22A and 22B protruding from ring 20 are generally oriented so that they symmetrically oppose each other with respect to the center of annular ring 20 but can be staggered in different angular positions depending upon the application. Legs 22A and 22B are also generally mirror images of each other, but can have different geometries and attributes depending upon the specific application. Legs 22A and 22B can also contain mounting holes 16. Mounting holes 16 can be recessed into legs 22A and 22B with optional counterbores 42 to provide a more snag resistant geometry.
(21) FIG. 1B presents a similar perspective view of embodiment 130 but with an optional stiffening plate 52 located underneath surface 36 so as to provide more support if rigidity is lacking in surface 36. Surface 36 becomes sandwiched between underside surfaces 38 of bases 62 of legs 22A and 22B and stiffening plate 52. Bolts 50 can be inserted through counterbores 42 and mounting holes 16 of legs 22A and 22B and passed through both the holes 56 of surface 36 and the holes 57 of optional stiffening plate 52 and then secured with nuts 54. It is understood that stiffening plate 52 is not limited for use with only embodiment 130 but can also be shaped differently and can be used with other presented embodiments as well.
(22) FIG. 1C presents a similar perspective view of the embodiment 130, but with optional bolts 48 inserted from the underside direction of surface 36 instead of inserted from the topside direction of surface 36. Mounting holes 16 originating from underside surfaces 38 of legs 22A and 22B can comprise of blind holes or through holes and can be smooth bored or internally threaded to accept threaded bolts 48 from such underside direction. Bolts 48 can be inserted through holes 57 of stiffening plate 52, passed through holes 56 of surface 36 and then threaded into mounting holes 16 of legs 22A and 22B. It is understood that other means of attachment of embodiment 130 to fixed surface 36 are also possible, as well as other means of attachment of additionally presented embodiments to other additionally presented surfaces.
(23) FIG. 1D presents another perspective view of the first presented embodiment 130 mounted to a fixed surface 36 with the use of bolts 50. FIG. 1D demonstrates how legs 22A and 22B bend downward enough below the bottom side 26 of ring 20 so that a rope or line 44, or alternatively multiple ropes or lines 44, can fit through the gap created between the bottom side 26 of ring 20 and the top surface of fixed surface 36 onto which the underside surfaces 38 of the bases 62 of legs 22A and 22B are mounted to. Although there is no set limit for the inside diameter 28 of ring 20, inside diameter 28 is generally made large enough to allow for two or more diameters of line 44 to pass through without interfering with each other. There is also no set limit for the outside diameter 30 of ring 20, but outside diameter 30 is generally large enough to provide a radial thickness of ring 20 of dimensions to allow for the construction of rounded edges 68A and 68B on the inside diameter 28 and rounded edges 72A and 72B on the outside diameter 30 of ring 20 to be formed to predetermined sizes so as to act as fairlead surfaces to redirect the direction of line 44. Consequently, the axial thickness of ring 20 is also generally of a dimension so as to allow for the similar construction of rounded edges 68A and 68B on the inside diameter 28 and rounded edges 72A and 72B on the outside diameter 30 of ring 20 to be formed to predetermined sizes so as to act as fairlead surfaces to redirect the direction of line 44. The radial thickness of ring 20 is defined as half the difference between outside diameter 30 and inside diameter 28 while the axial thickness of ring 20 is defined as the distance between the greatest vertical projection of the top side surface 24 with that of a corresponding greatest vertical projection of bottom side surface 26 in the opposing direction. The rounded edges 68A, 68B, 72A and 72B are made to predetermined dimensions based on the material characteristics of the particular line 44 used so as to prevent damage to the line 44 material from bending at too sharp of a radius. Rounded edge 68A is a round formed with the intersection of a plane created from the top surface 24 with the projected wall of the axial bore of the inside diameter 28 of ring 20, and rounded edge 68B is a round formed with the intersection of a plane created from the bottom surface 26 with the projected wall of the axial bore of the inside diameter 28 of ring 20. Rounded edges 68A and 68B are generally made of the same dimensions as each other but do not necessarily need to be the same. Consequently rounded edge 72A is a round formed on the intersection of a plane created from the top surface 24 with the projected wall made from projecting an axial cylinder created around the circumference of outside diameter 30 of ring 20, and rounded edge 72B is a round formed on the intersection of a plane created from the bottom surface 26 with the projected wall made from projecting an axial cylinder around the circumference of outside diameter 30 of ring 20. Rounded edges 72A and 72B are again generally made of the same dimensions as each other, but do not necessarily need to be the same. The dimensions of rounded edges 68A and 68B are generally, but not necessarily, of the same dimensions as rounded edges 72A and 72B respectively. Legs 22A and 22B merge with the outside diameter 30 of ring 20 in a contiguous manner with generally smooth and flowing transitions 54 in all directions of such merge so as create a snag free fairlead surface and to prevent other undesirable attributes created from sharp corners or irregular transitions. Fillet 58A and fillet 58B are formed on legs 22A and 22B respectively where legs 22A and 22B merge with the bottom surface 26 of ring 20 and transition with the outside diameter 30 of ring 20 so as to further provide contiguous smooth and flowing transitions. In addition, in this first presented embodiment 130 as well as in others, the outside geometries of bases 62 of legs 22A and 22B are made generally circular with respect to a plane parallel to underside surfaces 38 so as to provide rounded surfaces on the sides of the bases 62 of legs 22A and 22B of predetermined radii that are capable of acting as additional turning fairleads for line 44.
(24) FIG. 1E further illustrates embodiment 130 mounted to surface 36 and demonstrates how line 74 can be attached to ring 20 in an attachment mode representing a fixed pad eye while line 44 can be simultaneously fed through the inner diameter 28 of ring 20 in an arrangement representing a fairlead. Line 74 can be attached to ring 20 using a cow hitch type connection, a standard knot or any other means of attachment depending upon the application. Region 78 defines the section of ring 20 that lies between adjacent legs 22A and 22B. Line 74 is constrained to stay in region 78 due to legs 22A and 22B acting as physical barriers to restrict any further movement of line 74 in a direction tangent to the circumference of outside diameter 30 of ring 20. Likewise region 82 defines another section of ring 20 that lies between adjacent legs 22A and 22B but on the opposing side of ring 20. Line 44 is constrained to stay in region 82 due to legs 22A and 22B again acting as physical barriers to restrict any further movement of line 44 beyond region 82 in a direction tangent to the circumference of outside diameter 30 of ring 20. As a result of these separate and isolated regions 78 and 82, lines 74 and 44 are generally restricted in their opportunity to be able to slide into and rub against each other whereas such interference could cause wear and additional friction. FIG. 1E also further illustrates how ring 20 contains rounded inside edges 68A and 68B as well as rounded outside edges 72A and 72B to provide round and gentle surfaces to act as a contact area for an attachment point or to act as fairlead turning surfaces for lines 74 or 44. The radii of rounded edges 68A, 68B, 72A and 72B are predetermined in size from the characteristics of the line material used, but generally range from one to as much as three times the radius of the line 44 or 74. In some cases, especially in situations of intermittent motion or light loading, the radii of rounded edges 68A, 68B, 72A and 72B can be smaller than the radius of the line 44 or 74. Generally the dimensional sizes of the radius of both rounded edges 68A, 68B, 72A and 72B are all made the same as each other but in some applications it may be desired to have outside rounded edges 72A and 72B smaller than the respective inside rounded edges 68A and 68B or vise versa so as to increase the cross sectional area of ring 20 for increased strength.
(25) FIG. 1F displays the first presented embodiment 130 in a bottom view. FIG. 1F further illustrates that bases 62 of legs 22A and 22B generally present round projections onto the bottom plane created by underside surfaces 38 so as to act as additional redirect fairleads for further redirecting line 44 through additional turning angles. Fillet 58A between leg 22A and the bottom surface 26 of ring 20 as well as fillet 58B between leg 22B and the bottom surface 26 of ring 20 provide for a smooth and gradual transition for line 44 to pass over if line 44 exits from inside diameter 28 of ring 20 in the proximity of either one of legs 22A or 22B and impinges onto the sides of such legs 22A or 22B.
(26) FIG. 2A is a top view perspective of a second presented embodiment 132 in which the annular ring 20 is in a canted orientation with respect to the fixed surface 36 onto which such presented embodiment is mounted to. A reference plane 89 defines the canted orientation of ring 20 with respect to fixed surface 36 and is formed by any three independent points 84, 85 and 86 located on the inside diameter 28 of ring 20. For certain rigging applications, canting the orientation of ring 20 with respect to the surface 36 onto which embodiment 132 is mounted to provides additional room on one side of the embodiment for the connection of larger rigid fittings, thimbles or other uses while maintaining or reducing the projected distance of ring 20 on the opposing side above surface 36 to reduce snag hazards. The degree of canting between plane 89 and fixed surface 36 depends upon the particular application but is generally about 15 degrees for the more common optional applications.
(27) FIG. 2B is a similar top view perspective of a second presented embodiment 132 in which the annular ring is in a canted orientation with respect to a mounting surface 36. The canted orientation provides additional clearance between the underside of annular ring 20 and the mounting surface 36 to allow for attaching items that may be larger than a line such as a typical rigid metal shackle 91 or a typical line or wire rope 93 implementing a typical rigging thimble 95. Sectional cut 2C-2C is also shown and is later presented in FIG. 2C.
(28) FIG. 2C is a cross sectional view 2C-2C of the second presented embodiment 132 which further illustrates the canted orientation of the annular ring 20 with respect to the surface 36 onto which embodiment 132 is mounted to. A side view of plane 89 is further illustrated to present the canting of annular ring 20 with respect to mounting surface 36.
(29) FIG. 3 displays a top view of a third presented embodiment 134. Embodiment 134 presents bases 62 of legs 22A and 22B widened so as to provide more stability and also provides more space to include a multitude of mounting holes 16. It is understood from previous FIG. 1B and FIG. 1C that embodiment 134 can also consist of holes 16 originating from the top side of legs 22A and 22B with countersinks 42, or comprise of blind holes originating from the bottom side of legs 22A and 22B, with said holes being either smoothly bored or internally threaded, among other options.
(30) FIG. 4 displays a fourth presented embodiment 136 which contains three legs 22A, 22B and 22C protruding from ring 20 to provide extra stability and more locations for attaching lines or components in a pad eye configuration and for providing more passages to be used in a fairlead configuration. Region 78 consists of the section of ring 20 located between its transitions with leg 22A and leg 22B. Region 82 consists of the section of ring 20 located between its transitions with leg 22B and leg 22C, while region 98 consists of the section of ring 20 located between its transitions with leg 22A and leg 22C. Each of the regions 78, 82 and 98 can act as either a location for attaching a line or other rigging component in a pad eye arrangement, or as a location for redirecting a line in a fairlead arrangement. Line 74 is shown attached in a pad eye arrangement to the presented embodiment 136 in region 78 but could also be attached in region 82 and/or in region 98. The presented embodiment 136 portrays line 44 being redirected in region 82 in a fairlead arrangement and line 96 being redirected in region 98 in another fairlead arrangement, with the side of base 62 of leg 22A acting as an additional means of line redirect. It is understood that any such regions 78, 82 and 98 can be used for either pad eye type attachment locations or as fairlead locations, and the sides of the bases 62 of any legs 22A, 22B or 22C can also be used as an additional means of line redirection. Embodiment 136 also contains mounting holes 16. It is understood from previous FIG. 1B and FIG. 1C that embodiment 136 can also consist of holes 16 originating from the topside of legs 22A, 22B and 22C with counterbores 42, or comprise of blind holes originating from the underside surfaces 38 of legs 22A, 22B and 22C, with said holes being smoothly bored or internally threaded, among other mounting options.
(31) FIG. 5 displays a fifth presented embodiment 138 which contains four legs 22A, 22B, 22C and 22D protruding from ring 20 to provide yet more extra stability and more locations for pad eye type attachment points or fairlead passages. Region 78 consists of the section of ring 20 located between its transitions with leg 22A and leg 22B. Region 82 consists of the section of ring 20 located between its transitions with leg 22B and leg 22C. Region 98 consists of the section of ring 20 located between its transitions with leg 22C and leg 22D and region 106 consists of the section of ring 20 between leg 22D and leg 22A. Each of the regions 78, 82 and 98 and 106 can act as either a pad eye type attachment location or as a fairlead passage, and the sides of bases 62 of any leg 22A, 22B, 22C or 22D can be used as an additional means of line redirection.

Typical sailboat 202 comprises of jib sail 204 and mast 206. Jib sail 204 contains sail clew 208. Embodiment 130 is shown mounted to boat deck 174. The jib sheet 169 connects to jib clew 208 and is deflected by a typical rigging bull's eye 172. Jib sheet 169 eventually terminates on its other end to a typical winch or cleat which is not shown. The in-hauler line 164 is shown terminated to the presented embodiment 130 in a pad eye arrangement and then passing through, or around, a typical rigging bull's eye 172 which is used to deflect jib sheet 169 and further control the aerodynamic shape of jib sail 204. In-hauler line 164 then runs back through presented embodiment 130 from an essentially vertical direction and is redirected to an essentially horizontal direction by embodiment 130 in a fairlead arrangement. It is understood that embodiment 130 is employed for illustration purposes and the illustration is not limited to embodiment 130 and could also employ other presented embodiments in the same function. In-hauler line 164 then runs back to boat cockpit 210. A magnified area is indicate by circle 7B and is described in the subsequent FIG. 7B.
(36) FIG. 7B is a magnified view of FIG. 7A showing more detail to the in-hauler 2:1 arrangement. In-hauler line 164 is attached by a knot or splice 214 to one side of annular ring 20 of presented embodiment 130. In-hauler line 164 then runs upward essentially vertically through or around typical rigging bull's eye 172 and then back downward though the center of annular ring 20 of presented embodiment 130. Typical rigging bull's eye 172 passes around jib sheet 169. In-hauler line 164 is redirected from an essentially vertical direction to an essentially horizontal direction by presented embodiment 130. The direction of in-hauler line 164 can be further redirected in a fairlead arrangement by being deflected by the side of either leg 22A or leg 22B.
(37) FIG. 8A presents embodiment 130 mounted on or made integral to a typical sailboat traveler type car 183 so as to create a barber hauler arrangement. Typical sailboat 202 comprises of jib sail 204 and mast 206. Jib sail 204 contains sail clew 208. Presented embodiment 130 is mounted or made integral to typical traveler car 183. It should be noted that the arrangement is not limited to embodiment 130 and could employ other presented embodiments as well. Traveler car 183 is mounted with a prismatic joint to typical traveler car track 185 so as to allow an essentially athwartship direction of movement along boat deck 174. This essentially athwartship translation of presented embodiment 130, mounted or made integral to traveler car 183, allows for further change of the lead angle of jib sheet 169 with respect to sail clew 208. By pulling on or easing out on in-hauler line 164 and positioning traveler car 183 in a selected athwartship location, further adjustment to the aerodynamic shape of jib sail 204 is made possible. A magnified area is indicate by circle 8B and is described in the subsequent FIG. 8B.
(38) FIG. 8B is a magnified view of 8B showing more detail to the barber hauler arrangement mounted on boat deck 174. Presented embodiment 130 is mounted to the upper structural surface of traveler car 183 or alternatively presented embodiment 130 or any other presented embodiments could be made integral to the upper structural surface of traveler car 183 so as to create a traveler car with such presented embodiment formed into its structure. In-hauler line 164 is attached to embodiment 130 by a knot or splice 214, run through or around a typical rigging bulls eye 172 and then looped back through annular ring 20 and then between adjacent legs 22A and 22B of embodiment 130 so as to act as a fairlead. Typical rigging bull's eye 172 is passed around jib sheet 169. Traveler car 183 can move laterally along traveler track 185 so as the change the in-hauler line 164 direction of pull with respect to typical rigging bull's eye 172, which in turn changes the lead angle of jib sheet 169 with respect to jib sail clew 208. It is understood that presented embodiment 130 used with this figure could be substituted with other presented embodiments as well and is not limited to only embodiment 130.
(39) The presented embodiments are generally intended to be constructed from metal such as aluminum or stainless steel but could be constructed out of any other suitable materials including plastics and composites. Fabrication methods include machining, investment casting, injection molding, forging or any other suitable fabrication process. Further processing may include anodizing, electropolishing, tumbling, powder coating, or any other such secondary processes.
