Abstract
Description
- The present invention relates to a pair of pliers, and more particularly to a pair of pliers for operating a workpiece, such as a pipe, rod and the like.
- A conventional pliers comprise an elongated shank, a fixed jaw locked onto at least one end of the shank, and a movable jaw pivotally mounted on the at least one end of the shank and movable relative to the fixed jaw. The fixed jaw has a surface provided with a plurality of locking teeth. The movable jaw has a surface provided with a first toothed face and a second toothed face. The first toothed face of the movable jaw is provided with a plurality of first engaging teeth. The second toothed face of the movable jaw is provided with a plurality of second engaging teeth. Thus, a workpiece is clamped between the locking teeth of the fixed jaw, the first engaging teeth of the first toothed face of the movable jaw and the second engaging teeth of the second toothed face of the movable jaw. In such a manner, the movable jaw is movable relative to the fixed jaw to clamp workpieces of different sizes by a pivot action of the movable jaw. However, when the swinging angle of the movable jaw exceeds a determined value, the locking teeth of the fixed jaw, the first engaging teeth of the first toothed face of the movable jaw and the second engaging teeth of the second toothed face of the movable jaw cannot engage the surface of the workpiece efficiently, so that the workpiece easily slips from the fixed jaw and the movable jaw of the pliers, thereby causing inconvenience to the user.

U.S. Patent No. 2,559,973 ;6,026,714 ;6,742,419 ;7,044,030 and7,096,764 . - The present invention is to mitigate and/or obviate the disadvantage of the conventional pliers.
- The primary objective of the present invention is to provide a pair of pliers having an enhanced friction to prevent from incurring a slip during operation of the pliers.
- Another objective of the present invention is to provide a pair of pliers, wherein the first contact point of the locking teeth of the fixed jaw and the second contact point of the first engaging teeth of the first toothed face of the movable jaw have a larger friction with the surface of the workpiece by the special angle design of the fixed jaw and the movable jaw to enhance the clamping force of the fixed jaw and the movable jaw on the surface of the workpiece, so that the workpiece is clamped by the fixed jaw and the movable jaw exactly and closely to prevent the workpiece from being slipped from the fixed jaw and the movable jaw during operation of the pliers.
- A further objective of the present invention is to provide a pair of pliers, wherein each of the locking teeth of the fixed jaw, the first engaging teeth and the second engaging teeth of the movable jaw is designed to have an obtuse angle to enhance the strength of the locking teeth, the first engaging teeth and the second engaging teeth.
- A further objective of the present invention is to provide a pair of pliers, wherein the first tangent line of the locking teeth of the fixed jaw and a face of a contacting one of the locking teeth of the fixed jaw have an included angle ranged between 37° and 45° to prevent the workpiece from being slipped from the fixed jaw due to a deformation of the workpiece.

Thefixed jaw 15 has a surface provided with a plurality oflocking teeth 150. Themovable jaw 20 has a surface provided with afirst toothed face 21 and asecond toothed face 22 which are arranged to form a substantially V-shaped profile. Thefirst toothed face 21 of themovable jaw 20 is provided with a plurality of firstengaging teeth 210. Thesecond toothed face 22 of themovable jaw 20 is provided with a plurality of secondengaging teeth 220. - Referring to
Figs. 1-3 , when the pliers are used to operate aworkpiece 30, such as a pipe, rod and the like, theworkpiece 30 is clamped between thelocking teeth 150 of thefixed jaw 15, the firstengaging teeth 210 of the firsttoothed face 21 of themovable jaw 20 and the secondengaging teeth 220 of the secondtoothed face 22 of themovable jaw 20. In such a manner, each of thelocking teeth 150 of thefixed jaw 15 has an angle (D) ranged between 90° and 92°. Each of the firstengaging teeth 210 of the firsttoothed face 21 of themovable jaw 20 has an angle (B) ranged between 93° and 97°, and each of the secondengaging teeth 220 of the secondtoothed face 22 of themovable jaw 20 also has an angle (B) ranged between 93° and 97°. - A line (L1) passing apexes of the first
engaging teeth 210 of the firsttoothed face 21 of themovable jaw 20 and a line (L2) passing apexes of the secondengaging teeth 220 of the secondtoothed face 22 of themovable jaw 20 have an included angle (H) ranged between 134° and 136°. - In addition, the
locking teeth 150 of thefixed jaw 15 and theworkpiece 30 have a first contact point (P1) and a first tangent line (L3), the firstengaging teeth 210 of the firsttoothed face 21 of themovable jaw 20 and theworkpiece 30 have a second contact point (P2) and a second tangent line (L4), and the secondengaging teeth 220 of the secondtoothed face 22 of themovable jaw 20 and theworkpiece 30 have a third contact point (P3) and a third tangent line (L5). A line (L6) passing the first contact point (P1) and a center (O) of theworkpiece 30 and a line (L8) passing the third contact point (P3) and the center (O) of theworkpiece 30 have an included angle (G) ranged between 160° and 176°. A line (L7) passes the second contact point (P2) and the center (O) of theworkpiece 30. The first tangent line (L3) and a face of a contacting one of thelocking teeth 150 of the fixedjaw 15 have an included angle (A) ranged between 37° and 45°. The second tangent line (L4) and a face of a contacting one of the firstengaging teeth 210 of thefirst toothed face 21 of themovable jaw 20 have an included angle (E) ranged between 40° and 55°. The third tangent line (L5) and a face of a contacting one of the secondengaging teeth 220 of the secondtoothed face 22 of themovable jaw 20 have an included angle (C) ranged between 45° and 60°. - In practice, the
workpiece 30 is clamped by the first contact point (P1) of thelocking teeth 150 of the fixedjaw 15, the second contact point (P2) of the firstengaging teeth 210 of thefirst toothed farce 21 of themovable jaw 20 and the third contact point (P3) of the secondengaging teeth 220 of the secondtoothed face 22 of themovable jaw 20, so that theworkpiece 30 is positioned by thefixed jaw 15 and themovable jaw 20 and is operated by rotation of theshank 10. In such a manner, the first contact point (P1) of thelocking teeth 150 of thefixed jaw 15 and the second contact point (P2) of the firstengaging teeth 210 of the firsttoothed face 21 of themovable jaw 20 produce a larger friction with the surface of theworkpiece 30 by the special angle design of the fixedjaw 15 and themovable jaw 20 to enhance the clamping force of thefixed jaw 15 and themovable jaw 20 on the surface of theworkpiece 30, so that theworkpiece 30 is clamped by thefixed jaw 15 and themovable jaw 20 exactly and closely to prevent theworkpiece 30 from being slipped from thefixed jaw 15 and themovable jaw 20 during operation of the pliers. - Accordingly, the first contact point (P1) of the
locking teeth 150 of the fixedjaw 15 and the second contact point (P2) of the firstengaging teeth 210 of the firsttoothed face 21 of themovable jaw 20 have a larger friction with the surface of theworkpiece 30 by the special angle design of thefixed jaw 15 and themovable jaw 20 to enhance the clamping force of thefixed jaw 15 and themovable jaw 20 on the surface of theworkpiece 30, so that theworkpiece 30 is clamped by thefixed jaw 15 and themovable jaw 20 exactly and closely to prevent theworkpiece 30 from being slipped from thefixed jaw 15 and themovable jaw 20 during operation of the pliers. In addition, each of thelocking teeth 150 of thefixed jaw 15, the firstengaging teeth 210 and the secondengaging teeth 220 of themovable jaw 20 is designed to have an obtuse angle to enhance the strength of thelocking teeth 150, the firstengaging teeth 210 and the secondengaging teeth 220. Further, the first tangent line (L3) of thelocking teeth 150 of the fixedjaw 15 and a face of a contacting one of thelocking teeth 150 of the fixedjaw 15 have an included angle (A) ranged between 37° and 45° to prevent theworkpiece 30 from being slipped from the fixedjaw 15 due to a deformation of theworkpiece 30. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention as defined in the appended claims.
