Abstract

TORQUE TOOL USING COLORS FOR IDENTIFICATION. This is a torque tool that includes multiple drill bits, a handle, a pointer, and a scale ring. Each drill bit includes a colored area. In use, the handle is connected to one of the selected drill bits. The handle is operable to set multiple maximum torque values transferable to the drill bit from the handle corresponding to the colored areas of the drill bits. The pointer is formed on the handle. The scale ring includes multiple colored areas corresponding to the colored areas of the drill bits. The scale ring is rotated around the handle as it is operated to set the maximum torque values, thus aligning the pointer with one of the colored areas of the scale ring corresponding to the colored area of one of the selected drill bits.

Claims (10)

  1. 1. TORQUE TOOL characterized in that it comprises: multiple drills (11), each of which comprises a colored area; a handle (30) for connection to one of the selected drills (11), wherein the handle (30) is operable to define multiple maximum torque values transferable to the drill (11) from the handle (30) corresponding to the colored areas of the drills (11); a label (60) supported on the handle (30), wherein the label (60) comprises multiple colored areas (61, 62, 63, 64) corresponding to the colored areas of the drills (11) and multiple numbers (61a, 62a, 63a, 64a) located in the colored areas (61, 62, 63, 64) of the label (60) which correspond to the maximum torque values; a pointer (54) formed on the handle (30); a scale ring (80) rotated around the handle (30) as the handle (30) is operated to set the maximum torque values, thus aligning the pointer (54) with a value on the scale ring (80) according to one of the numbers (61a, 62a, 63a, 64a) in one of the colored areas (61, 62, 63, 64) corresponding to the label (60) to the colored area of one of the selected drills (11).
  2. 2. TORQUE TOOL, according to claim 1, characterized in that the handle (30) comprises a frame (53) and a cavity (56) in the frame (53), in which the label (60) is inserted into the cavity (56).
  3. 3. TORQUE TOOL, according to claim 2, characterized in that it comprises a transparent panel (59) connected to the frame (53) to hold the label (60) in the cavity (56).
  4. 4. TORQUE TOOL, according to claim 3, characterized in that the label (60) is printed on a lower face of the transparent panel (59).
  5. 5. TORQUE TOOL, according to claim 1, characterized in that the label (60) comprises four colored areas (61, 62, 63, 64).
  6. 6. TORQUE TOOL, according to claim 1, characterized in that the scale ring (80) comprises multiple colored areas (82, 83, 84, 85) corresponding to the colored areas (61, 62, 63, 64) of the label (60), wherein each of the colored areas (82, 83, 84, 85) of the scale ring (80) represents one of the maximum torque values.
  7. 7. TORQUE TOOL, according to claim 6, characterized in that the scale ring (80) comprises four colored areas (82, 83, 84, 85), wherein the label (60) comprises four colored areas (61, 62, 63, 64).
  8. 8. TORQUE TOOL, according to claim 2, characterized in that the pointer (54) is a pointed portion of the frame (53) extending towards the scale ring (80).
  9. 9. TORQUE TOOL, according to claim 8, characterized in that it comprises a torque unit (55) located between the pointer (54) and the cavity (56).
  10. 10. TORQUE TOOL, according to claim 1, characterized in that it comprises a lens (70) extending around the handle (30) to cover the scale ring (80).

Description

BACKGROUND OF THE INVENTION FIELD OF THE INVENTION [001] The present invention relates to torque tools and, more particularly, to a torque tool that uses colors for identification. PREVIOUS RELATED TECHNIQUE [002] There are various tools, such as closed-end wrenches, fixed-end wrenches, adjustable wrenches, Allen wrenches, socket wrenches, and related components. Pressing or printing is often used to provide a tool with an inscription to show a trademark, an aesthetic pattern, or the size of the tool. [003] The use of the above-mentioned processes for making the marking is not without problems, particularly when the marking is used to show the tool size. For example, a user may have to wipe the grease off the tool to read the marking to know the tool size, as the marking is often covered wholly or partially by grease. In addition, the user may have to turn the tool over to read the marking, since the marking is often held on a lower face of the tool in an operating position. [004] U.S. Patent No. 4,982,627 discloses a tool identification system in which a color chart displays a range of ten colors, each color indicating a particular number. A sequence of indicated numerals represents the size value of a tool, in fractional inches or metric size. However, the user must memorize the correspondence of the colors with the numerals. The user will have trouble choosing drill bits of the right sizes if he or she forgets the correspondence. Consequently, the user may bring drill bits of the wrong sizes to a job site and fail at a task. Alternatively, the user may be forced to bring drill bits of all sizes to the job site, and this is a burden. In operation, the user may choose drill bits of the wrong sizes before obtaining the drill bits of the appropriate size, and this is a waste of time. [005] Document CN 2118617 discloses an adjustable wrench including a handle, a jaw formed in the handle, another jaw movably connected to the handle, a scale in fractional inches and another scale in metric size. Each scale provides the correspondence of the value of each size to an actual size of a gap between the jaws. However, the scales may be covered with grease or stains. [006] Furthermore, no wrench was provided with anything that would allow a user to know the proper torque value to apply to a workpiece, such as a nut and threaded pin, without causing damage to the workpiece. Therefore, the user cannot apply an inappropriate torque value to engage a nut with a threaded pin so that the nut can be easily disengaged from the threaded pin due to vibration. [007] The present invention is therefore intended to avoid or at least alleviate the problems encountered in the prior art. SUMMARY OF THE INVENTION [008] The main objective of the present invention is to provide a torque tool that uses colors for identification. [009] To achieve the aforementioned objective, the torque tool includes multiple drill bits, a handle, a pointer, and a scale ring. Each drill bit includes a colored area. In use, the handle is connected to one of the selected drill bits. The handle is operable to set multiple maximum torque values transferable to the drill bit from the handle corresponding to the colored areas of the drill bits; the pointer is formed on the handle. The scale ring includes multiple colored areas corresponding to the colored areas of the drill bits. The scale ring is rotated around the handle as it is operated to set the maximum torque values, thus aligning the pointer with one of the colored areas of the scale ring corresponding to the colored area of one of the selected drill bits.
