Definitions
- the present invention relates to a hand tool and method for manufacturing the same.
- Hand tools such as open-end wrenches, closed-end wrenches, torx wrenches, ratchet wrenches, sockets, are provided with at least one opening configured to be sleeved with a fastener, and a size of each of said opening is conformed with a metric size or an imperial size so as to apply to the fastener to be rotated.
- the conventional fasteners have various sizes in the metric standard and the imperial standard, and a conventional hand tool is suitable to use in two sizes of the fasteners at most. Therefore, the operator has to prepare a number of hand tools of different specifications or sizes for operation, which is inconvenient to carry and high cost.
- a hand tool with an opening suitable for two different sizes of fasteners are provided, and the opening is defined by a plurality of sidewalls processed with convex surfaces, engaging grooves, abutting surface, or the like, which has a complicate structure and a high processing cost, and the fasteners are easy to deform or disengage therefrom due to small contact area.
- the present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
- the main object of the present invention is to provide a hand tool and method for manufacturing the same, and the hand tool is suitable to fasteners in different sizes and has a simple structure and is easy to manufacture.
- the present invention provides a method for manufacturing a hand tool, including following steps of: determining a target size according to a first standard range and a second standard range; and forming a hand tool body according to the target size.
- the hand tool body includes an opening and a plurality of sidewalls defining the opening, and a distance between two said sidewalls radially opposite to each other corresponds to the target size.
- One of the first standard range and the second standard range is a metric size range
- the other of the first standard range and the second standard range is an imperial size range.
- the first standard range includes a first upper limit value and a first lower limit value
- the second standard range includes a second upper limit value and a second lower limit value.
- the target size is determined to be greater than or equal to the first lower limit value and less than or equal to at least one of the first upper limit value and the second upper limit value.
- the target size is determined to be greater than or equal to the first lower limit value and less than or equal to the first upper limit value.
- the present invention further provides a hand tool, manufactured by the method as described above.
- the hand tool is a wrench or a socket, and the opening is disposed on one end of the hand tool body and configured to be assembled with a fastener.
- a method for manufacturing a hand tool of the present invention includes following steps of: determining a target size according to a first standard range and a second standard range; and forming a hand tool body 10 according to the target size.
- the first standard range includes a first upper limit value and a first lower limit value
- the second standard range includes a second upper limit value and a second lower limit value.
- the target size is determined to be greater than or equal to the first lower limit value and less than or equal to at least one of the first upper limit value and the second upper limit value.
- the target size is determined to be greater than or equal to the first lower limit value and less than or equal to the first upper limit value.
- the hand tool body 10 includes an opening 11 and a plurality of sidewalls 12 defining the opening 11, and a distance between two said sidewalls 12 radially opposite to each other corresponds to the target size. Therefore, the opening 11 can be used for fasteners in both the metric standard and the imperial standard, and the hand tool is convenient to process and provides wide range of applications and good operating stability.
- the first standard range is the imperial size range
- the second standard range is the metric size range.
- the imperial size range conforming to the standard is between 17.51 mm (the first lower limit value) and 17.76 mm (the first upper limit value)
- the metric size range conforming to the standard is between 17.05 mm (the second lower limit value) and 17.30 mm (the second upper limit value).
- the target size may be determined between 17.51 mm and 17.76 mm (such as 17.67mm) so that the opening 11 is conformed to the imperial size range and can be used for the fastener in size 11/16"; the target size is close to the metric size range so that the opening 11 is also usable for the fastener in size 17 mm, which is convenient to manufacture.
- a difference between the target size and the second lower limit value is less than or equal to 0.8 mm.
- a difference between the first lower limit value and the second upper limit value is less than or equal to 0.4 mm, which avoids large size difference and allows the plurality of sidewalls 12 to be stably abutted against the fastener.
- the method for manufacturing the hand tool is to form the distance between the two said sidewalls 12 to be the same with the target size, which allows the two said sidewalls 12 to be stably abutted against the fasteners with different sizes.
- the plurality of sidewalls 12 are unnecessary to be further processed and can provide stable abutment with the fastener so as to have good operation effect.
- the method for manufacturing the hand tool further includes a step of arranging a first size mark 20 corresponding to the metric size range and a second size mark 30 corresponding to the imperial size range on the hand tool body 10.
- the first size mark 20 and the second size mark 30 respectively include at least one of characters, numbers and patterns, as shown in figures 1 and 2 , which is convenient to use.
- the method for manufacturing the hand tool further includes a step of arranging at least one recognition structure 40 on the hand tool body 10. When the target size is within the metric size range, one of the at least one recognition structure 40 is arranged adjacent to or at the first size mark 20.
- the at least one recognition structure 40 When the target size is within the imperial size range, one of the at least one recognition structure 40 is arranged adjacent to or at the second size mark 30 so as to show the standard size to which the opening 11 conforms.
- the at least one recognition structure 40 includes a first recognition portion 41 corresponding to the first size mark 20 and a second recognition portion 42 corresponding to the second size mark 30.
- the first recognition portion 41 and the second recognition portion 42 respectively include a pattern with a round, oval or polygonal shape.
- the first recognition portion 41 is different from the second recognition portion 42, such as hexagonal borders and round borders shown in figures 1 and 2 .
- Shapes of the first recognition portion 41 and the second recognition portion 42 are different to each other so that it is convenient to know that a size of the opening 11 is conformed to the imperial size range of size 11/16" and also conformed to the metric size range of size 17 mm.
- the at least one recognition structure may include patterns, concave or convex structures, color blocks, colored text, or the like.
- one of the first and the second size marks conformed to the standard may include a red pattern, and one of the first and the second size marks non-conformed to the standard may include a green pattern; one of the first and the second size marks conformed to the standard may include a round border, and one of the first and the second size marks non-conformed to the standard may have no border.
- the method for manufacturing the hand tool further includes step of forming a plurality of notches 13 communicated with the opening 11, and each of the plurality of notches 13 is located between adjacent two of the plurality of sidewalls 12, which is convenient to be assembled with the fastener and prevents corners of the fastener from abrasion.
- the target size is determined to be between the first lower limit value and the second upper limit value.
- the first standard range is the metric size range
- the second standard range is the imperial size range. Take size 5/8" and size 16 mm as an example, the imperial size range conforming to the standard is between 15.91 mm (the second lower limit value) and 16.16 mm (the second upper limit value), and the metric size range conforming to the standard is between 16.05 mm (the first lower limit value) and 16.27 mm (the first upper limit value).
- the target size may be determined between 16.05 mm 16.16 mm (such as 16.15mm) so that the opening 11a is conformed to both the imperial size range and the metric size range, which has a wide range of applications.
- the shapes of the first recognition portion 41 and the second recognition portion 42 are the same so as to represent that the opening 11a is conformed to two respective sizes.
- the hand tool body 10a may include a plurality of the opening 11a, 11b, shapes, size and types of said openings 11a, 11b may be identical to or different from one another.
- the present invention further provides a hand tool, manufactured by the method as described above.
- the hand tool may be a wrench (as shown in figures 1-3 ) or a socket (as shown in figure 4 ), and the opening 11, 11a, 11b, 11c is disposed on one end of the hand tool body 10, 10a, 10b.
- the distance between the two said sidewalls 12 is between a lower limit value of one of the metric size range and the imperial size range and an upper limit value of the other of the metric size range and the imperial size range so that the opening 11a is conformed to both the imperial size range and the metric size range.
