[0048] I. Introduction This specification describes several exemplary embodiments, at least some of which relate to adjustable pliers, such as retaining ring or snap-lock pliers. The exemplary pliers consist of two halves, with a handle at the proximal end and a working tip at the distal end. These two halves are rotatably coupled to each other via studs. Squeezing the handles together moves the working tip. In a standard pliers configuration, the pliers halves intersect a longitudinal axis extending from the proximal end to the distal end, such that the working tip of each pliers half (or each half) is located on the side of the longitudinal axis opposite to the handle of that half. In this case, squeezing the handles together will cause the working tips to move toward each other, similar to scissors. Alternatively, it is possible to configure the pliers with a "reverse" or expanded configuration, such that squeezing the handles together moves the working tips away from each other. For example, in the case where the working tip and handle of the first pliers half are located on one side of the longitudinal axis and the working tip and handle of the second pliers half are located on the other side of the longitudinal axis, squeezing the handles together will cause the working tips to separate. The adjustable pliers described in this article can switch between a standard pliers configuration and a reverse configuration without separating the first pliers half and the second pliers half.

[0049] Standard and reverse clamp configurations can be used for a variety of applications. For example, both configurations can be used to place and remove retaining rings, such as snap rings. Clamps that close when squeezed can be used to retract an inner retaining ring for insertion into a conduit or other annular structure. Conversely, clamps that open when squeezed can be used to expand an outer retaining ring, allowing it to slide over a shaft or similar structure.

[0050] The exemplary embodiments described herein include adjustable pliers having a second pliers half with a slot for receiving a stud coupled to a first pliers half. The slot extends along a path from a first end to a second end, wherein the first and second ends of the path are aligned with a transverse axis or a first axis. Furthermore, the second pliers half extends from the handle to the working tip in a direction substantially aligned with a longitudinal axis or a second axis perpendicular to the transverse axis. Performance parameters are defined at least in part by the relationship between the dimensions of the slot or the working tip of the second pliers half. In some embodiments, the performance parameters are one or more ratios of the dimensions of the slot or the working tip of the first pliers half. The applicant has determined that the performance parameters described herein contribute to achieving better performance of the adjustable pliers. Advantageously, the performance parameters described herein allow a user to operate the adjustable pliers in both a first and a second working position, such that during operation, the force on the adjustable pliers pushes the stud into the slot end rather than along the slot path. Furthermore, the performance parameters described herein enable the first and second working tips to cross each other during transitions between the first and second working positions without tilting or contacting each other, or to reduce tilting or contact. As another example, the performance parameters described herein enable smooth transitions between the first and second working positions. II. Example of an adjustable pair of pliers

[0051] Figures 1 to 4 illustrate embodiments of adjustable pliers, which can be adjusted to have a standard configuration or a reverse configuration by repositioning the studs relative to the pliers halves. For example, Figure 1 shows an adjustable pliers 100, which includes a first pliers half 120 and a second pliers half 140 coupled via studs 160. The first pliers half 120 includes a first handle 122, a first working tip 132, and a first connector body 130 between the first handle 122 and the first working tip 132. Similarly, the second pliers half 140 includes a second handle 142, a second working tip 152, and a second connector body 150 between the second handle 142 and the second working tip 152.

[0052] Figure 2A shows the adjustable pliers 100 in a first working position. The adjustable pliers 100 is shown to be substantially aligned with the longitudinal axis 102, wherein the first handle 122 and the second handle 142 are positioned toward the proximal end 104 of the longitudinal axis 102, and the first working tip 132 and the second working tip 152 are positioned toward the distal end 106 of the longitudinal axis 102.

[0053] As the adjustable pliers 100 opens and closes, the first pliers half 120 and the second pliers half 140 rotate around the stud 160. Therefore, as the adjustable pliers 100 opens and closes, the paths of the first handle 122, the second handle 142, the first working tip 132, and the second working tip 152 are all arc-shaped. However, considering the respective positions of the first handle 122, the second handle 142, and the first working tip 132, the second working tip 152 near the proximal end 104 and the distal end 106 of the longitudinal axis 102 when the adjustable pliers are operated, the first handle 122, the second handle 142, and the first working tip 132, the second working tip 152 substantially move in the transverse direction indicated by the transverse axis 108.

[0054] In some embodiments, the stud 160 may be fixed. As used herein, "fixed" means in a predetermined position relative to the first clamp half 120. Therefore, in some embodiments, the stud 160 is rotatable, even if it may be inserted into and held in a specific position within the first clamp half 120. Furthermore, in some embodiments, the stud 160 may be completely stationary relative to the first clamp half 120. For example, the stud 160 may be integrally formed with the first clamp half 120.

[0055] Furthermore, in some embodiments, the force applied to the handle of the adjustable pliers is substantially aligned with the first and second directions at the end of the slot path. This force on one half of the pliers pushes in the opposite direction toward the stud 160 of the other half of the pliers, i.e., the end that enters the slot.

[0056] As illustrated in Figure 2A, when the adjustable pliers 100 is positioned in the first position, the first handle 122 and the first working tip 132 of the first pliers half 120 are both located on the same side of the longitudinal axis 102. Similarly, the second handle 142 and the second working tip 152 are both located on the other side of the longitudinal axis 102. Therefore, pushing the first handle 122 and the second handle 142 toward each other, also referred to herein as "squeezing" the adjustable pliers (depicted by arrows 190 and 191), will cause the first working tip 132 and the second working tip 152 to move away from each other (depicted by arrows 192 and 193). On the other hand, when the adjustable pliers 100 is positioned in the second working position, as shown in Figure 2B, the first pliers half 120 and the second pliers half 140 intersect the longitudinal axis 102. Therefore, the first handle 122 is located on one side of the longitudinal axis 102, while the first working tip 132 is located on the other side of the longitudinal axis 102. Similarly, the second handle 142 of the second pliers half 140 is located on one side of the longitudinal axis 102, while the second working tip 152 is located on the other side of the longitudinal axis 102. In this configuration, pushing the first handle 122 and the second handle 142 toward each other will cause the first working tip 132 and the second working tip 152 to move toward each other (as depicted by arrows 194 and 195).

[0057] To switch the adjustable pliers 100 from the first position shown in FIG. 2A to the second position shown in FIG. 2B, the relative positions of the first pliers half 120, the second pliers half 140, and the stud 160 can be adjusted. This adjustment is facilitated by moving the stud 160 through different positions in the slot 170 of the second pliers half 140 that holds the stud 160. For example, when the adjustable pliers 100 is in the first working position shown in FIG. 2A, which is associated with the reverse configuration, squeezing the first handle 122 and the second handle 142 causes the first working tip 132 and the second working tip 152 to separate, and the stud 160 is positioned at the first end 172 of the slot 170. On the other hand, when the stud 160 moves to the second end 174 of the slot 170, the adjustable pliers 100 is in the second working position shown in FIG. 2B, which is associated with the standard configuration, where squeezing the handle causes the working tips to come together.

[0058] In both positions, during operation of the adjustable pliers, the force on the second handle and the second working tip is in the lateral direction, as shown in Figures 3 and 4. For example, in Figure 3, where the adjustable pliers 100 is in the first working position, the second handle 142 is pushed towards the first handle 122, i.e., in the first leftward direction 196, and the expanded outer retaining ring 202 attempts to close, i.e., pushes the second working tip 152 towards the second leftward direction 198, parallel to the first leftward direction 196. In Figure 4, where the adjustable pliers 100 is in the second working position, the second handle 142 is again pushed towards the first handle 122, i.e., in the first leftward direction 196, and the inner retaining ring 204 attempts to expand, i.e., pushes the second working tip 152 towards the second leftward direction 198.

[0059] Therefore, during operation of the adjustable pliers 100 in either the first or second working position, the second handle 142 pushes the right side of the stud 160. To hold the adjustable pliers 100 in either working position, the two ends of the slot 170 are advantageously closed on the right side, and the path of the slot 170 extends at least partially to the left. Thus, during operation, the force on the adjustable pliers 100 pushes the stud 160 into one end of the slot, rather than along the path of the slot.

[0060] The adjustable pliers can be switched from a first working position to a second working position. Figures 5A and 5B show the adjustable pliers 100 in the first working position, Figures 9A and 9B show the adjustable pliers 100 in the second working position, and Figures 6A to 8A and Figures 6B to 8B show the adjustable pliers switching from the first working position to the second working position.

[0061] During the transition between the first and second working positions, the stud 160 moves along path 180 of slot 170. Specifically, in FIG. 6A, the adjustable pliers 100 is in the first transition position, where the stud 160 is in the first transition position on path 180 of slot 170. In the first transition position, the stud 160 is closer to the first end 172 of slot 170 than to the second end 174 of slot 170. Furthermore, in FIG. 7A, the adjustable pliers 100 is in the second transition position, where the stud 160 is in the second transition position on path 180 of slot 170. Compared to the first position in path 180, the second position in path 180 is closer to the second end 174 of slot 170. Furthermore, in FIG. 8A, the adjustable pliers 100 is in the third transition position, where the stud 160 is in the third transition position on path 180 of slot 170. In the third transition position, the stud 160 is closer to the second end 174 of the slot 170 than to the first end 172 of the slot 170.

[0062] During the transition between the first and second working positions, the first working tip 132 and the second working tip 152 move relative to each other. Specifically, the first working tip 132 and the second working tip 152 cross each other without tilting or contacting each other, as shown in Figures 6B to 8B.

[0063] Figures 10A to 10C show various configurations of the second pliers half 1040 having a groove 1070 and a second working tip 1052. The groove 1070 has a continuously curved path 1080. The second working tip 1052 has a cross-sectional length C.

[0064] The slot 1070 in the second pliers half 1040 is formed by a hole with a radius, such that the slot 1070 has width. As shown in FIG10A, the path 1080 includes a first end 1082 and a second end 1088. As shown in FIG10C, the path 1080 extends along a first direction 1062 at the first end 1082 and extends along a second direction 1064 substantially parallel to the first direction 1062 at the second end 1088. The first end 1082 and the second end 1088 of the path 1080 are aligned on the transverse axis 1008.

[0065] From the first end 1082 of path 1080, path 1080 extends to the outermost lateral position 1084, which is laterally offset by B relative to the lateral axis 1008 and the first end 1082 of path 1080. At the outermost lateral position 1084, the path 1080 of groove 1070 extends along the first curved portion 1083 (see Figure 10C).

[0066] From the outermost lateral position 1084, the path 1080 of the slot 1070 extends to the nearest side position 1086, spaced apart from the first end 1082 of the path 1080 by a longitudinal offset D relative to the longitudinal axis 1002. The longitudinal offset D allows the second working tip 1052 to pass through the working tip of the first pliers half, and is therefore greater than the cross-sectional length of the second working tip 1052, as described above. At the nearest side position 1086 of the path 1080, the path 1080 extends along the second curved portion 1087 (see Figure 10C).

[0067] Therefore, path 1080 extends from the first end 1082 to the outermost lateral position 1084, from the outermost lateral position 1084 to the nearest side position 1086, and from the nearest side position 1086 to the second end 1088. In some embodiments, the nearest side position 1086 is located between the first end 1082 and the second end 1088 relative to the lateral axis 1008. As shown in Figures 10A and 10C, the outermost lateral position 1084 is located on the first curved portion 1083, while the nearest side position is located on the second curved portion 1087. Furthermore, the second curved portion 1087 extends to the second end 1088.

[0068] The performance parameter may be defined at least in part by a first ratio of the lateral offset B to half the width of the slot 1070, the first ratio being expressed as a radius RA. In some embodiments, the hole radius across the slot 1070 may be the same. In other embodiments, the hole radius may vary. The first ratio may be referred to as the hook ratio. In some embodiments, the first ratio defines the hook shape of the slot, which maintains the orientation of the second clamp half 1040 and the first clamp half in a first working position and a second working position.

[0069] Furthermore, the performance parameter may be defined at least in part by a second ratio of longitudinal offset D to cross-sectional length C. This second ratio may be referred to as the tip movement ratio. In some embodiments, the second ratio defines the gap through which the working tips of the second working tip 1052 and the first pliers half intersect during transitions between the first and second working positions. Furthermore, in some embodiments, the intersection of the working tips may be achieved without tilting or contacting each other, or with reduced tilting or contact. Furthermore, in some embodiments, a smooth transition between the first and second working positions may be achieved. In some embodiments, the performance parameter is defined by both the first and second ratios.

[0070] As shown in Figure 10A, along the transverse axis 1008, there is a distance E between the first end 1082 and the second end 1088 of path 1080. Furthermore, the center point 1081 of the radius of curvature of the second curved portion 1087 is located between the first end 1082 and the second end 1088 of path 1080 relative to the transverse axis 1008. Along the transverse axis 1008, there is an offset F between the first end 1082 of path 1080 and the center point 1081 of the radius of curvature of the second curved portion 1087. In other words, the offset F is also the distance between the first end 1082 of path 1080 and the nearest side position 1086 of path 1080 relative to the transverse axis 1008.

[0071] The performance parameter is defined at least in part by a third ratio of (i) offset F and (ii) distance E. The third ratio defines the relative position of the nearest side position 1086 between the first end 1082 and the second end 1088 of path 1080 with respect to the lateral axis 1008. In some embodiments, the performance parameter is defined by at least two of the first, second, and third ratios. Furthermore, in some embodiments, the performance parameter is defined by the first, second, and third ratios.

[0072] The first, second, and third ratios may have values ​​within a certain range. For example, the first ratio may have a value in the range of about 0.55 to about 1.10, including 0.55 to 1.10. As used herein, "about" means a variation of 10% higher or lower than the stated value. As another example, the second ratio may have a value in the range of about 1.03 to about 2.28, including 1.03 to 2.28. As yet another example, the third ratio may have a value in the range of about 0.26 to about 0.35, including 0.26 to 0.35.

[0073] Figure 11 illustrates various configurations of the second clamp half 1140 having a groove 1170. The groove 1170 has a continuously curved path 1180. As shown in Figure 11, the path 1180 includes a first end 1182 and a second end 1188. The path 1180 extends along a first direction at the first end 1182 and extends along a second direction substantially parallel to the first direction at the second end 1188. The first end 1182 and the second end 1188 of the path 1180 are aligned with the transverse axis 1108.

[0074] Based on the values ​​of the first, second, or third ratio, the second pliers half and slot described herein may have different shapes. For example, when the first ratio has a value of approximately 0.55, the second ratio has a value of approximately 1.03, and the third ratio has a value of approximately 0.26, the second pliers half and slot may take the form of second pliers half 1040 and slot 1070, or be similar in form. As another example, when the first ratio has a value of approximately 1.10, the second ratio has a value of approximately 2.28, and the third ratio has a value of approximately 0.35, the second pliers half and slot may take the form of second pliers half 1140 and slot 1170, or be similar in form.

[0075] The performance parameter may be defined at least in part by a fourth ratio of the radius of curvature RG to the radius RA of the first curved portion 1083. In some embodiments, the performance parameter is defined by at least two of the first, second, third, and fourth ratios. Furthermore, in some embodiments, the performance parameter is defined by the first, second, third, and fourth ratios. In some embodiments, the fourth ratio has a value of about 1.19 or about 2.19.

[0076] Furthermore, the performance parameter may be defined at least in part by a fifth ratio of the radius of curvature RH of the second curved portion 1087. In some embodiments, the performance parameter is defined by at least two of the first, second, third, fourth, and fifth ratios. In some embodiments, the performance parameter is defined by the first, second, third, fourth, and fifth ratios. In some embodiments, the fifth ratio has a value of approximately 3.48 or approximately 4.38.

[0077] Figures 12A to 12C show various configurations of the second clamp half 1240 having a slot 1270 and a second working tip 1252. The slot 1270 has a path 1280 and includes two linear portions. The second working tip 1252 has a cross-sectional length C.

[0078] The slot 1270 in the second clamp half 1240 is formed by a hole having a radius, such that the slot 1270 has a width. Half of the width of the slot 1270 can be represented as the radius RA. In some embodiments, the hole radius across the slot 1270 may be the same. In other embodiments, the hole radius may vary. As illustrated in FIG12A, the path 1280 includes a first end 1282 and a second end 1288. As illustrated in FIG12C, the path 1280 extends along a first direction 1262 at the first end 1282 and extends along a second direction 1264 substantially parallel to the first direction 1262 at the second end 1288. The first end 1282 and the second end 1288 of the path 1280 are aligned with the transverse axis 1208.

[0079] From the first end 1282 of path 1280, path 1280 extends to a lateral outermost position 1284, spaced apart from the first end 1282 of path 1280 by a lateral offset similar to lateral offset B relative to the lateral axis 1208. An angle K exists between the lateral outermost position 1284 and the lateral axis 1208. In some embodiments, angle K is approximately 60 degrees. At the lateral outermost position 1284, the path 1280 of groove 1270 extends along a first curved portion 1283 having a radius of curvature RG.

[0080] From the outermost lateral position 1284, the path 1280 of the slot 1270 extends to the nearest side position 1286, which is spaced apart from the first end 1282 of the path 1280 relative to the longitudinal axis 1202 by a longitudinal offset similar to a longitudinal offset D. This longitudinal offset allows the second working tip 1252 to pass through the working tip of the first pliers half and is therefore greater than the cross-sectional length of the second working tip 1252, as described above. As shown in Figure 12C, at the nearest side position 1286 of the path 1280, the path 1280 extends along a second curved portion 1287 having a radius of curvature RH.

[0081] Therefore, path 1280 extends from the first end 1282 to the outermost laterally position 1284, from the outermost laterally position 1284 to the nearest-side position 1286, and from the nearest-side position 1286 to the second end 1288. An angle J exists between the second end 1288 of path 1280 and the lateral axis 1208. In some embodiments, angle J is approximately 60 degrees. Groove 1270 includes a first linear portion 1285 between the first curved portion 1283 and the second curved portion 1287, and a second linear portion 1289 between the second curved portion 1287 and the second end 1288 of path 1280.

[0082] As shown in Figure 12A, a distance similar to distance D exists between the first end 1282 and the second end 1288 of path 1280 along the transverse axis 1208. Furthermore, the center point 1281 of the radius of curvature of the second curved portion is located between the first end 1282 and the second end 1288 of path 1280 relative to the transverse axis 1208. Along the transverse axis 1208, an offset similar to offset F exists between the first end 1282 of path 1280 and the center point 1281 of the radius of curvature of the second curved portion 1287.

[0083] The performance parameters of the adjustable pliers illustrated in Figures 12A to 12C can be defined in the same or similar manner as those for the adjustable pliers illustrated in Figures 10A to 10C. In some embodiments, the first ratio has a value of about 1. Furthermore, in some embodiments, the second ratio has a value of about 1.05. Furthermore, in some embodiments, the third ratio has a value of about 0.34. Furthermore, in some embodiments, the fifth ratio has a value of about 1.39 or about 2.49.

[0084] Figure 13 illustrates various configurations of the second clamp half 1340 having a slot 1370. The slot 1370 has a path 1380 and includes two linear portions. As shown in Figure 13, the path 1380 includes a first end 1382 and a second end 1388. The path 1380 extends along a first direction 1362 at the first end 1382 and extends along a second direction substantially parallel to the first direction 1362 at the second end 1388. The first end 1382 and the second end 1388 of the path 1380 are aligned with the transverse axis 1308.

[0085] As shown in Figure 5B, the first connector body 130 of the first pliers half 120 may have an outer surface 136 on one side of the adjustable pliers 100 and an inner surface 138 facing the second pliers half 140. Similarly, the second connector body 150 of the second pliers half 140 may have an outer surface 156 on the other side of the adjustable pliers 100 and an inner surface 158 facing the first pliers half 120. In some embodiments, the inner surface 138 of the first connector body 130 of the first pliers half 120 may be positioned against the inner surface 158 of the second connector body 150 of the second pliers half 140, such that as the adjustable pliers 100 opens and closes, the inner surface 138 of the first connector body 130 of the first pliers half 120 slides over the inner surface 158 of the second connector body 150 of the second pliers half 140. In other embodiments, the inner surface 138 of the first connector body 130 of the first pliers half 120 may be spaced apart from the inner surface 158 of the second connector body 150 of the second pliers half 140 by a spacer disposed on a stud or otherwise positioned between the inner surface 138 of the first connector body 130 of the first pliers half 120 and the inner surface 158 of the second connector body 150 of the second pliers half 140.

[0086] In some embodiments, the inner surface 138 of the first connector body 130 of the first pliers half 120 and the inner surface 158 of the second connector body 150 of the second pliers half 140 may each be flat, such that the first pliers half 120 and the second pliers half 140 engage with each other on a flat interface. This configuration allows the first pliers half 120 and the second pliers half 140 to rotate relative to each other about the stud 160 without tilting or contacting each other. Furthermore, the stud 160 can move from the first end 172 of the slot 170 to the second end 174 of the slot 170 without requiring the first pliers half 120 or the second pliers half 140 to tilt relative to each other. Advantageously, this allows the user to adjust the pliers 100 without requiring any complex movement of either pliers half.

[0087] The performance parameter may be defined at least in part by a sixth ratio of the width of the connector body along the transverse axis 108 to the distance between the first end and the second end of the path. This sixth ratio allows the adjustable pliers to be fitted inside a workpiece, such as a shaft with a retaining ring. Adjustable pliers with a smaller connector body width may be more easily fitted into smaller spaces. In some embodiments, the performance parameter is defined by at least two of the first, second, third, fourth, fifth, and sixth ratios. Furthermore, in some embodiments, the performance parameter is defined by the first, second, third, fourth, fifth, and sixth ratios. In some embodiments, the sixth ratio has a value of about 2.08, about 2.16, or about 1.96.

[0088] As described herein, performance parameters can be defined by a first ratio, a second ratio, a third ratio, a fourth ratio, a fifth ratio, a sixth ratio, or a combination of such ratios. Using more ratios to define performance parameters can provide better or more reliable performance for the adjustable pliers. For example, using a first ratio, a second ratio, and a third ratio will provide better or more reliable performance for the adjustable pliers compared to using only the first and second ratios.

[0089] The first working tip 132 and the second working tip 152 may each include a separate pin 134, 154, as shown in FIG2A. In some embodiments, the first working tip 132 and the second working tip 152 may also be needle-eye tips, or another configuration.

[0090] In some embodiments, the first handle 122 and the second handle 142 may each be covered. For example, the first handle 122 and / or the second handle 142 may be coated with plastic or fitted with a rubber sleeve, etc. Furthermore, in some embodiments, the first handle 122 and the second handle 142 may each have a width. The width of the first handle 122 and / or the second handle 142 can provide comfort for the user. For example, the width of the first handle 122 is shown in Figures 5B to 9B. III. Examples

[0091] The following examples illustrate specific embodiments of the present invention. It is articulated for the purpose of interpretation only and should not be considered to limit the scope of the invention. Each instance comprises a second vise halves having slots for housing studs coupled to the first vise halves, as described above. The slot is extended on a path from the first to the second end, where the first and second ends of the path are aligned with the transverse axis. Furthermore, the second vise half extends from the handle to the working tip in a direction substantially aligned with the longitudinal axis perpendicular to the transverse axis. These instances vary in various sizes, shapes, and scales. In detail, the slots in each of Examples 1 to 6 are continuously bent, similar to the embodiments shown in Figures 10A to 10C. Furthermore, the slots in each of Examples 7 to 8 are continuously bent, similar to the embodiment shown in FIG. In contrast to this, the slot in Example 9 includes two linear parts, similar to the embodiments shown in Figures 12A to 12C. Furthermore, the slot in each of instances 10 to 12 comprises two linear parts, similar to the embodiment shown in FIG. The applicant has judged that by judiciously controlling selected dimensions and ratios (the performance parameters described above), as expressed in the foregoing examples, the adjustable pliers can transition smoothly between the first and second working positions. [instance] [1]

[0092] In the first example, the vise size of the adjustable vise is 3845. The tip diameter of the working tip is thirty-eight thousandths of an inch and the tip angle of the working tip is 45 degrees. The length of the cross section of the working tip of the second vise halves intercepted along the longitudinal axis is 0.17.

[0093] The slot in the second vise halves is formed by a hole with a radius of 0.1005 in. such that the width of the slot is 0.201 in. From the first end of the path, the path extends to the outermost position of the lateral transverse offset that is spaced 0.057 inches apart from the first end of the path with respect to the lateral axis. Therefore, the ratio of the lateral offset to the hole diameter of the slot is 0.57. At the transverse outermost position, the path of the slot extends along the first bending portion with a curvature radius of 0.12. The resulting ratio of the radius of curvature of the first bending portion to the radius of the slot hole is 1.19.

[0094] From its outermost lateral position, the path of the slot extends to its closest position with a longitudinal offset of 0.23 inches relative to the first end of the path and the longitudinal axis. This longitudinal offset allows the working tip of the second pliers half to pass over the working tip of the first pliers half, and is therefore greater than the cross-sectional length of the working tip of the second pliers half, as described above. In practice, the ratio of the longitudinal offset of the working tip of the second pliers half to its cross-sectional length is 1.35. At the closest position of the path, the path extends along a second bend with a radius of curvature of 0.35. The ratio of the radius of curvature of the second bend to the radius of the slot hole is 3.48.

[0095] Along the transverse axis, the distance between the first end and the second end of the path is 0.45 inches. The center point of the radius of curvature of the second bend is located between the first end and the second end of the path relative to the transverse axis. Along the transverse axis, the offset between the first end of the path and the center point of the radius of curvature of the second bend is 0.121 inches. Therefore, (i) the ratio of the offset between the first end of the path and the center point of the radius of curvature of the second bend to (ii) the distance between the first end and the second end of the path is 0.27. The width of the connector body along the transverse axis is 0.938 inches, such that the ratio of the connector body width to the distance between the first end and the second end of the path is 2.08. [Example] [2]

[0096] In the second example, the adjustable pliers have a plier size of 3890. The working tip has a tip diameter of 0.38 inches and a tip angle of 90 degrees. The length of the cross-section of the working tip of the second half of the pliers, taken along the longitudinal axis, is 0.12.

[0097] The slot in the second half of the clamps is formed by a hole with a radius of 0.1005 inches, resulting in a slot width of 0.201 inches. From the first end of the path, the path extends to its outermost position, offset laterally by 0.057 inches from the first end of the path relative to the lateral axis. Therefore, the ratio of the lateral offset to the slot hole diameter is 0.57. At the outermost position, the slot path extends along a first bend with a radius of curvature of 0.12. The ratio of the radius of curvature of the first bend to the radius of the slot hole is 1.19.

[0098] From its outermost lateral position, the path of the slot extends to its closest position with a longitudinal offset of 0.23 inches relative to the first end of the path and the longitudinal axis. This longitudinal offset allows the working tip of the second pliers half to pass over the working tip of the first pliers half, and is therefore greater than the cross-sectional length of the working tip of the second pliers half, as described above. In fact, the ratio of the longitudinal offset of the working tip of the second pliers half to its cross-sectional length is 1.92. At the closest position of the path, the path extends along a second bend with a radius of curvature of 0.35. The ratio of the radius of curvature of the second bend to the radius of the slot hole is 3.48.

[0099] Along the transverse axis, the distance between the first end and the second end of the path is 0.45 inches. The center point of the radius of curvature of the second bend is located between the first end and the second end of the path relative to the transverse axis. Along the transverse axis, the offset between the first end of the path and the center point of the radius of curvature of the second bend is 0.121 inches. Therefore, (i) the ratio of the offset between the first end of the path and the center point of the radius of curvature of the second bend to (ii) the distance between the first end and the second end of the path is 0.27. The width of the connector body along the transverse axis is 0.938 inches, such that the ratio of the connector body width to the distance between the first end and the second end of the path is 2.08.

Therefore, the ratio of the lateral offset to the slot hole diameter is 0.57. At the outermost position, the slot path extends along a first bend with a radius of curvature of 0.12. The ratio of the radius of curvature of the first bend to the radius of the slot hole is 1.19.

[0102] From its outermost lateral position, the path of the slot extends to its closest position with a longitudinal offset of 0.23 inches relative to the first end of the path and the longitudinal axis.

In practice, the ratio of the longitudinal offset of the working tip of the second pliers half to its cross-sectional length is 1.35. At the closest position of the path, the path extends along a second bend with a radius of curvature of 0.35. The ratio of the radius of curvature of the second bend to the radius of the slot hole is 3.48.

[0103] Along the transverse axis, the distance between the first end and the second end of the path is 0.45 inches. The center point of the radius of curvature of the second bend is located between the first end and the second end of the path relative to the transverse axis. Along the transverse axis, the offset between the first end of the path and the center point of the radius of curvature of the second bend is 0.121 inches. Therefore, (i) the ratio of the offset between the first end of the path and the center point of the radius of curvature of the second bend to (ii) the distance between the first end and the second end of the path is 0.27. The width of the connector body along the transverse axis is 0.938 inches, such that the ratio of the connector body width to the distance between the first end and the second end of the path is 2.08.

From the first end of the path, the path extends to its outermost position, offset laterally by 0.057 inches from the first end of the path relative to the lateral axis. Therefore, the ratio of the lateral offset to the slot hole diameter is 0.57. At the outermost position, the slot path extends along a first bend with a radius of curvature of 0.12. The ratio of the radius of curvature of the first bend to the radius of the slot hole is 1.19.

[0106] From its outermost lateral position, the path of the slot extends to its closest position with a longitudinal offset of 0.23 inches relative to the first end of the path and the longitudinal axis. This longitudinal offset allows the working tip of the second pliers half to pass over the working tip of the first pliers half, and is therefore greater than the cross-sectional length of the working tip of the second pliers half, as described above. In fact, the ratio of the longitudinal offset of the working tip of the second pliers half to its cross-sectional length is 1.92. At the closest position of the path, the path extends along a second bend with a radius of curvature of 0.35.

The width of the connector body along the transverse axis is 0.973 inches, such that the ratio of the connector body width to the distance between the first end and the second end of the path is 2.16. [Example] [6]

[0113] The slot in the second half of the clamps is formed by a hole with a radius of 0.1005 inches, resulting in a slot width of 0.201 inches. From the first end of the path, the path extends to its outermost position, offset laterally by 0.057 inches from the first end of the path relative to the lateral axis.

The ratio of the radius of curvature of the first bend to the radius of the slot hole is 2.19.

[0118] From its outermost lateral position, the path of the slot extends to its closest position with a longitudinal offset of 0.43 inches relative to the first end of the path and the longitudinal axis. This longitudinal offset allows the working tip of the second pliers half to pass over the working tip of the first pliers half, and is therefore greater than the cross-sectional length of the working tip of the second pliers half, as described above.

The ratio of the radius of curvature of the first bend to the radius of the slot hole is 2.19.

[0122] From its outermost lateral position, the path of the slot extends to its closest position, longitudinally offset by 0.43 inches relative to the longitudinal axis and the first end of the path. This longitudinal offset allows the working tip of the second pliers half to pass over the working tip of the first pliers half, and is therefore greater than the cross-sectional length of the working tip of the second pliers half, as described above.

From the first end of the path, the path extends to its outermost position, offset laterally by 0.1 inches from the first end of the path relative to the lateral axis. Therefore, the ratio of the lateral offset to the slot hole diameter is 1. At the outermost position, the slot path extends along a first bend with a radius of curvature of 0.22. The ratio of the radius of curvature of the first bend to the slot hole radius is 2.19.

[0126] From its outermost lateral position, the path of the slot extends to its closest position with a longitudinal offset of 0.58 inches relative to the first end of the path and the longitudinal axis. This longitudinal offset allows the working tip of the second pliers half to pass over the working tip of the first pliers half, and is therefore greater than the cross-sectional length of the working tip of the second pliers half, as described above. In fact, the ratio of the longitudinal offset of the working tip of the second pliers half to its cross-sectional length is 1.04. At the closest position of the path, the path extends along a second bend with a radius of curvature of 0.25. The ratio of the radius of curvature of the second bend to the radius of the slot hole is 2.49.

[0127] Along the transverse axis, the distance between the first end and the second end of the path is 0.66 inches. The center point of the radius of curvature of the second bend is located between the first end and the second end of the path relative to the transverse axis. Along the transverse axis, the offset between the first end of the path and the center point of the radius of curvature of the second bend is 0.225 inches. Therefore, (i) the ratio of the offset between the first end of the path and the center point of the radius of curvature of the second bend to (ii) the distance between the first end and the second end of the path is 0.34. The width of the connector body along the transverse axis is 1.296 inches, such that the ratio of the connector body width to the distance between the first end and the second end of the path is 1.96.

In practice, the ratio of the longitudinal offset of the working tip of the second pliers half to its cross-sectional length is 1.05. At the closest position of the path, the path extends along a second bend with a radius of curvature of 0.14. The ratio of the radius of curvature of the second bend to the radius of the slot hole is 1.39.

The center point of the radius of curvature of the second bend is located between the first end and the second end of the path relative to the transverse axis. Along the transverse axis, the offset between the first end of the path and the center point of the radius of curvature of the second bend is 0.155 inches. Therefore, (i) the ratio of the offset between the first end of the path and the center point of the radius of curvature of the second bend to (ii) the distance between the first end and the second end of the path is 0.34. The width of the connector body along the transverse axis is 0.938 inches, such that the ratio of the connector body width to the distance between the first end and the second end of the path is 2.08.
