Description

Technical Field

[0001] The present application relates generally to sockets for driving fasteners, and more particularly to sockets and socket sets having indicia identifying the size and / or type of the corresponding socket. Background Art

[0002] Torque is commonly applied to workpieces, such as threaded fasteners, using a variety of wrenches and tools. Workpieces may have a variety of different sizes, shapes, and fittings. Therefore, many tools include drivers adapted to fit one or more different adapters, such as sockets, to engage and rotate different workpieces. Sockets are commonly used to drive hexagonal nuts or bolt heads. The appropriate size socket must be selected for each size of nut or bolt head. Sockets may be SAE sizes (also known as English or foot-pound systems) or metric sizes. For example, a 1 / 2 inch socket is provided for a nut with a diameter of 1 / 2 inch. Similarly, for metric sized nuts, a 10 mm socket is provided for a nut with a diameter of 10 mm.

[0003] Sockets are often sold in sets containing multiple sockets of different sizes. The set may include metric and / or SAE sized sockets. Socket sets are often sold with a socket carrier for storing and organizing the sockets, and the sockets are often arranged in order according to the socket size and grouped with other SAE or metric sockets. The size of the individual sockets is often displayed on the outer surface of the socket to allow identification of the socket required for the job and to allow the socket to be returned to the corresponding position in the socket carrier after the job is completed. However, visual identification of the sockets can be time consuming or difficult, especially for sockets that are close in size and when the sockets are not well marked. In addition, the size is often stamped or laser etched on the socket, which is often difficult to read, especially in low light conditions. It is also common for metric and imperial sockets to be mixed, causing confusion and requiring additional time to locate the required socket. Summary of the invention

[0004] The present invention generally relates to sleeves and sleeve sets that include markings on the respective sleeves for indicating the sleeve size and distinguishing sleeves of various sizes from one another. The markings on the sleeves may include a plurality of numerical markings on the outer surface of the sleeves and one or more lines between the numerical markings, wherein the number of lines varies between sleeves of adjacent sizes to further distinguish the sleeves. The alternating appearance of sleeves of adjacent sizes allows for quicker and easier identification of the proper sleeve, thereby saving time and reducing the possibility of error.

[0005] In one embodiment, the present invention generally relates to a sleeve set including a first sleeve and a second sleeve having a first size and a second size, respectively, each of the first sleeve and the second sleeve including a driving portion, a working portion, an outer surface, and a first numerical mark and a second numerical mark disposed on the outer surface. The first sleeve includes a first line disposed on the outer surface of the first sleeve and located between the first numerical mark and the second numerical mark.

[0006] In another embodiment, the present invention is generally directed to a socket set including a first socket and a second socket having a first size and a second size, respectively, each of the first socket and the second socket including an outer surface, a driving portion having a driving end, a workpiece engaging end, and first and second numerical markings disposed on the outer surface. The first socket includes a first line disposed on the outer surface of the first socket and located between the driving end and the first and second numerical markings, or between the workpiece engaging end and the first and second numerical markings.

[0034] Specific embodiments of the apparatus and method are disclosed herein. However, it should be understood that the disclosed embodiments are merely examples of the apparatus and method, which can be implemented in various forms. Therefore, the specific functional details disclosed herein should not be interpreted as limiting, but only as a basis for the claims and representative examples for teaching those skilled in the art to implement the present disclosure in various ways.

[0035] The present invention generally relates to a sleeve adapted to engage a head of a fastener (e.g., a polygonal nut or bolt, also referred to herein as a fastener head). The sleeves each include markings for indicating the size of the sleeve and distinguishing sleeves of different sizes from each other. The markings on the sleeves may include a plurality of numerical markings on the outer surface and / or one or more lines on the outer surface of some sleeves in a sleeve set. In one embodiment, the one or more lines are present on sleeves of alternating sizes. The inclusion of a plurality of numerical markings and one or more lines provides easier sleeve identification.

[0036] In one embodiment, the sleeve is suitable for cooperating with a lug wrench (e.g., a ratchet wrench, a torque wrench, or a cracking rod). Typically, the sleeves each include a body having a first end, a second end, and an outer surface. The first end and the second end may have a generally circular outer diameter, and the outer surface may be generally cylindrical and extend between the first end and the second end. The outer surface may include a protrusion or depression along the surface. The outer surface of the sleeve may also include a convex portion, and a digital mark and / or one or more lines may be provided on the convex portion of the outer surface. The convex portion may allow the user to operate more easily and provide a larger surface where a digital mark and / or line may be provided. The convex portion may provide tactile feedback to the user to identify the sleeve (similar to Braille). For example, when the sleeve is a metric size, an even-sized sleeve (e.g., 10, 20, 30 mm) may include a convex portion, while an odd-sized sleeve (e.g., 9, 19, 29 mm) may not include a convex portion.

[0037] The first end includes a first axial bore that defines a drive portion. The drive portion may have a generally square cross-sectional shape that extends at least partially into the body from the first end toward the second end. The drive portion is adapted to cooperatively engage a drive shaft or drive lug of a tool, such as a hand tool, a socket or ratchet wrench, a torque wrench, an impact driver, an impact wrench, and other tools in a well-known manner. The square cross-sectional shape may be, for example, approximately 1 / 4, 3 / 8, 1 / 2, or 3 / 4 inch square, or other SAE or metric dimensions. In yet another embodiment, the drive portion may be formed to have different cross-sectional shapes suitable for mating with tools of different shapes, for example, the cross-sectional shape may be a triangle, rectangle, pentagon, hexagon, heptagon, octagon, or other type of shape.

[0038] The second end includes a second axial bore that defines a working portion. The working portion may have a polygonal cross-sectional shape that extends axially into the body at least partially from the second end toward the first end. In one embodiment, the polygonal cross-sectional shape is generally hexagonal, suitable for engaging a fastener head, such as a hexagonal bolt head or nut. In another embodiment, the working portion can be formed to have different cross-sectional shapes suitable for mating with fastener heads of different shapes, such as triangular, rectangular, pentagonal, heptagonal, octagonal, hexagonal, double hexagonal, splined, or other types of shapes.

[0039] The sizes and dimensions of the various elements of the sockets described herein can be modified or adjusted for specific uses with one or more different tools. For example, the working portion of each socket can be adapted to receive different fastener sizes, e.g., 1 inch, 1 / 2 inch, 10 mm, 12 mm, 14 mm, etc., as is well known in the art. Similarly, the size of the drive portion can be adjusted to receive different sizes and types of drive shafts or drive lugs of the tool.

[0040] The digital markings may use numbers to indicate the size of the sleeve, such as metric sizes, such as 1 mm to 100 mm, including 1, 2, 3, 4, 5, 6 mm, etc. Alternatively, the digital markings may indicate the SAE size of the sleeve, such as 1 / 8 inch to 3 inches, including 1 / 4, 3 / 16, 1 / 8, 5 / 16, 3 / 8, 7 / 16, 1 / 2 inch, etc. The digital markings are preferably oriented so that at least the bottom of the numbers are parallel to the first end and the second end. The height of the digital markings can be selected to have a digital size that is recognizable to the user.

[0041] The digital markings can be flat, raised or recessed (e.g., by etching or embossing) to the surface of the sleeve to provide a unique appearance or provide tactile feedback. For example, the digital markings can be raised on even-numbered metric sleeves and flat or etched on odd-numbered metric sleeves, or can be raised on odd-numbered metric sleeves and flat or etched on even-numbered metric sleeves. The digital markings can also be colored, such as a color different from the color of the outer surface of the sleeve (e.g., if the outer surface is chrome or bright metal, the markings can be red). The colors of the digital markings on sleeves of different sizes can also be different. For example, for sleeves of alternating sizes, the colors of the digital markings can be alternating. For example, when the sleeve is metric size, sleeves of even sizes (e.g., 10, 20, 30 mm) can be a first color (e.g., red), while sleeves of odd sizes (e.g., 9, 19, 29 mm) can be a second color (e.g., blue). Additional digital markings can also be provided on the outer surface of the sleeve. The number of digital markings on each sleeve can be 2, 3, 4, 5, 6, 7 or 8. In one embodiment, there are at least two or three digital markings on the sleeve. The digital markings can be spaced apart from each other substantially equidistantly along the circumference on the outer surface. For example, two digital markings can be spaced apart from each other by about 180 degrees, three digital markings can be spaced apart from each other by about 120 degrees, and four digital markings can be spaced apart from each other by about 90 degrees. The number of digital markings on sleeves of different sizes can also be different. For example, an even-numbered metric sleeve can have two digital markings, while an odd-numbered metric sleeve can have three digital markings. The digital markings are arranged on the outer surface of the sleeve between the drive end and the working end. Each digital marking on the sleeve can be substantially equidistant from the drive end. Alternatively, the distance between the digital markings and the drive end can be different. In another embodiment, the digital markings on the first sleeve can be close to the working end, while the digital markings on the second sleeve of the adjacent size are positioned close to the drive end.

[0042] The line on the outer surface may be substantially located between the number marks. In one embodiment, a line is provided between the number marks, and the line is substantially located between the top and bottom of the number marks. When multiple lines are provided on the sleeve, the area between the number marks may define an area having a height substantially equal to the height of the number marks. A first line may be provided in the area near the drive end, and a second line may be provided in the area near the working end. Other lines may also be present in the area. The number of lines may be, for example, 0 to 20, particularly 0, 1, 2, 3, 4, 5, 6, 7 or 8, and more particularly 0, 1 or 2. Relative to the outer surface of the sleeve, the line may be flat, convex or concave to provide tactile feedback. The line may also have a color different from the color of the sleeve. For example, when the sleeve is metric size, the line on the sleeve of even size (e.g., 10, 20, 30 mm) may be a first color (e.g., red), while the line on the sleeve of odd size (e.g., 9, 19, 29 mm) may be a second color (e.g., blue). The line may be a solid line, a dashed line, or a line that is a combination of straight and dashed line portions.

[0043] In another embodiment, one or more lines may be disposed circumferentially on the outer surface between the top of the number marking and the drive end. Alternatively, one or more lines may be disposed between the working end and the number marking.

[0044] See also Figure 1 , a first set of sleeves 1000 of a first exemplary sleeve set is shown. The first set of sleeves 1000 may include sleeves 1100, 1200, 1300, and 1400. As shown, the first set of sleeves 1000 is a set of metric sleeves, wherein sleeve 1100 is an 11 mm sleeve, sleeve 1200 is a 12 mm sleeve, sleeve 1300 is a 13 mm sleeve, and sleeve 1400 is a 14 mm sleeve. It should be understood that the sleeves can be any corresponding size. It should also be understood that although four sleeves are shown, the first set of sleeves 1000 and / or the first sleeve set may include more or less than four sleeves, and four sleeves are shown for exemplary purposes only.

[0045] Each of the sleeves 1100, 1200, 1300, and 1400 in the first set of sleeves 1000 includes two numerical markings disposed approximately 180 degrees apart. Sleeves of odd sizes, such as sleeves 1100 and sleeves 1300 (e.g., 11 mm and 13 mm), further include a line extending circumferentially partially around the corresponding sleeve between the two numerical markings. The inclusion of numerical markings on all sleeves and one or more lines on sleeves of odd sizes reduces the risk of misidentifying sleeves of adjacent sizes (e.g., an 11 mm sleeve and a 12 mm sleeve).

[0046] See also Figure 2, an exemplary sleeve of the first set of sleeves 1000, such as sleeve 1300, is shown and described. It should be understood that each of the sleeves 1100, 1200, 1300, and 1400 can include similar features. For example, sleeve 1300 has an outer surface 1302, a drive end 1304, and a working end 1306. A first numerical marking 1308 is disposed on the outer surface 1302. Although Figure 2 A front view of the sleeve 1300 is shown, but it should be understood that the rear view of the sleeve can be substantially the same, and the rear view includes a second numerical marker that is substantially the same as the first numerical marker 1308. In this embodiment, the first numerical marker and the second numerical marker are arranged approximately 180 degrees apart. A first line 1314 and a second line 1316 are also arranged on the outer surface 1302, and the first line 1314 and the second line 1316 extend partially circumferentially around the sleeve between the first numerical marker and the second numerical marker.

[0047] Additionally, as shown, the first numerical indicia 1308 includes a first number 1310 and a second number 1312. However, it should be understood that the numerical indicia may include less than two numbers (eg, a single number) or more than two numbers, corresponding to the size of the sleeve.

[0048] See also Figures 3 to 7 , the sleeve 1300 has a driving portion 1318 or 1318' defined in the driving end 1304, and a working portion 1320, 1320' or 1320" defined in the working end 1306 opposite to the driving end 1304. The driving portions 1318 and 1318' may have a generally square cross-sectional shape of different sizes. The working portions 1320, 1320' and 1320" may also have different shapes. For example, the working portion 1320 may have a dodecagonal shape, the working portion 1320' may have a hexagonal shape, and the working portion 1320" may have a spline shape. It should be understood that the working portion may have any other cross-sectional shape suitable for mating with fastener heads of different shapes.

[0049] Figure 8 A second sleeve, such as sleeve 1400 , is shown that is adjacent in size to sleeve 1300 . Figure 8 The sleeve of is an even size and does not include a line between the numerical markings. However, the sleeve 1400 may include similar features as the sleeve 1300. For example, the sleeve 1400 has an outer surface 1402, a driving end 1404, and a working end 1406. The outer surface 1402 is provided with a first numerical marking 1408 consisting of a first number 1410 and a second number 1412. Although Figure 8A front view of the sleeve 1400 is shown, but it should be understood that the rear view of the sleeve can be substantially the same, and the rear view includes a second numerical mark that is substantially the same as the first numerical mark 1408. In this embodiment, the first numerical mark and the second numerical mark are separated by about 180 degrees. In addition, as shown, the first numerical mark 1408 includes a first number 1410 and a second number 1412. However, it should be understood that the numerical mark may include less than two numbers (e.g., a single number) or more than two numbers corresponding to the size of the sleeve.

[0050] See also Fig. 9 , a second set of sleeves 2000 of a second exemplary sleeve set is shown. The second set of sleeves 2000 may include sleeves 2100, 2200, 2300, and 2400. As shown, the second set of sleeves 2000 is a set of metric sleeves, wherein sleeve 2100 is an 11 mm sleeve, sleeve 2200 is a 12 mm sleeve, sleeve 2300 is a 13 mm sleeve, and sleeve 2400 is a 14 mm sleeve. In addition, it should be understood that although four sleeves are shown for exemplary purposes, the second set of sleeves 2000 and / or the second sleeve set may include more or less than four sleeves.

[0051] Each of the sleeves 2100, 2200, 2300, and 2400 in the second set of sleeves 2000 includes three numerical markings arranged approximately 120 degrees apart. Sleeves of odd sizes (e.g., sleeves 2100 and sleeves 2300) also include a line extending partially circumferentially around the corresponding sleeve between adjacent numerical markings. The inclusion of numerical markings on all sleeves and one or more lines on sleeves of odd sizes reduces the risk of misidentifying sleeves of adjacent sizes (e.g., an 11 mm sleeve and a 12 mm sleeve).

[0052] See also Fig. 10A and Fig. 10B, a front view and a rear view of an exemplary sleeve (e.g., sleeve 2300) of the second set of sleeves 2000 are shown and described. It should be understood that each of the sleeves 2100, 2200, 2300, and 2400 can include similar features. For example, the sleeve 2300 has an outer surface 2302, a drive end 2304 (similar to the drive end 1304 described above), and a working end 2306 (similar to the drive end 1306 described above). The outer surface 1302 is provided with a first numerical mark 2308, a second numerical mark 2322, and a third numerical mark 2324. In this embodiment, the first numerical mark 2308, the second numerical mark 2322, and the third numerical mark 2324 are separated by about 120 degrees. The outer surface 2302 is also provided with a first line 2314, and the first line 2314 extends circumferentially around the sleeve partially between the first numerical mark 2308 and the second numerical mark 2322. A second line 2316 is also provided on the outer surface 2302, and the second line 2316 extends partially circumferentially around the sleeve between the first numerical mark 2308 and the third numerical mark 2324. Similarly, a third line 2326 is also provided on the outer surface 2302, and the third line 2326 extends partially circumferentially around the sleeve between the second numerical mark 2322 and the third numerical mark 2324. In addition, as shown, each of the first numerical mark 2308, the second numerical mark 2322, and the third numerical mark 2324 includes a first number 2310 and a second number 2312. However, it should be understood that the numerical mark may include less than two numbers (e.g., a single number) or more than two numbers corresponding to the size of the sleeve.

[0053] Fig.11 A second sleeve, such as sleeve 2400, is shown as being adjacent in size to sleeve 2300. As shown, Fig.11 The sleeve 2400 is an even-numbered size and does not include a line between the number markings. However, the sleeve 2400 may include similar features to the sleeve 2300. For example, the sleeve 2400 has an outer surface 2402, a drive end 2404, and a working end 2406. The sleeve 2400 also includes a first number marking, a second number marking, and a third number marking that are arranged approximately 120 degrees apart. As shown, the outer surface 2402 is provided with a second number marking 2422 and a third number marking 2424. Although Fig.11 A rear view of sleeve 2400 is shown, but it is understood that the front view of the sleeve includes a first numerical indicia similar to sleeve 2300. In addition, as shown, each of the first numerical indicia, the second numerical indicia, and the third numerical indicia includes a first number 2410 and a second number 2412. However, it is also understood that the numerical indicia may include less than two numbers (e.g., a single number) or more than two numbers, corresponding to the size of the sleeve.

[0054] See also Fig.12, an exemplary third set of sleeves 3000 of the third sleeve set is shown. The third set of sleeves 3000 may include sleeves 3100, 3200, 3300, and 3400. As shown, the third set of sleeves 3000 is a set of metric sleeves, wherein sleeve 3100 is an 11 mm sleeve, sleeve 3200 is a 12 mm sleeve, sleeve 3300 is a 13 mm sleeve, and sleeve 3400 is a 14 mm sleeve. In addition, although four sleeves are shown for exemplary purposes, the third set of sleeves 3000 and / or the third sleeve set may include more or less than four sleeves.

[0055] Each of the sleeves 3100, 3200, 3300, and 3400 in the third set of sleeves 3000 includes two numerical markings disposed 180 degrees apart. Odd-sized sleeves (e.g., sleeves 3100 and 3300) also include one or more lines extending circumferentially around the sleeve above the numerical markings and / or near the drive end of the sleeve. The inclusion of numerical markings on all sleeves and one or more lines on odd-sized sleeves reduces the risk of misidentifying adjacent-sized sleeves (e.g., an 11 mm sleeve and a 12 mm sleeve).

[0056] See also Fig.13 , an exemplary sleeve of the third set of sleeves 3000, such as sleeve 3300, is shown and described. It should be understood that each of the sleeves 3100, 3200, 3300, and 3400 can include similar features. For example, sleeve 3300 has an outer surface 3302, a drive end 3304 (similar to drive end 1306 described above), and a working end 3306 (similar to drive end 1306 described above). A first numerical marking 3308 is provided on the outer surface 3302. Although Fig.13 A front view of sleeve 3300 is shown, but it should be understood that the rear view of sleeve can be substantially the same, and the rear view includes a second numerical mark. In this embodiment, the first numerical mark and the second numerical mark are separated by about 180 degrees. A first line 3314 is also provided on the outer surface 3302, and the first line 3314 extends around the sleeve circumference above the numerical mark and / or near the drive end 3304. In other words, the first line 3314 is arranged between the drive end 3304 and the first numerical mark and the second numerical mark. In another embodiment, the first line can be arranged below the numerical mark and / or near the working end 3306. In other words, the first line can be arranged between the working end 3306 and the first numerical mark and the second numerical mark.

[0057] In addition, as shown, the first numerical marking 3308 includes a first number 3310 and a second number 3312. However, it should be understood that the numerical marking may include less than two numbers (eg, a single number) or more than two numbers, corresponding to the size of the sleeve.

[0058] Each even-sized sleeve in the third set of sleeves 3000 also includes two number markings set approximately 180 degrees apart. However, each even-sized sleeve (e.g., sleeve 3200 and sleeve 3400) does not include a line extending around the sleeve circumference above the number markings and / or near the drive end of the sleeve.

[0059] See also Fig.14 , an exemplary fourth set of sleeves 4000 of a fourth sleeve set is shown. The fourth set of sleeves 4000 may include sleeves 4100, 4200, 4300, and 4400. As shown, the fourth set of sleeves 4000 is a set of metric sleeves, wherein sleeve 4100 is an 11 mm sleeve, sleeve 4200 is a 12 mm sleeve, sleeve 4300 is a 13 mm sleeve, and sleeve 4400 is a 14 mm sleeve. In addition, although four sleeves are shown for exemplary purposes, the fourth set of sleeves 4000 and / or the fourth sleeve set may include more or less than four sleeves.

[0060] Each of the sleeves 4100, 4200, 4300, and 4400 in the fourth set of sleeves 4000 includes three number markings arranged approximately 120 degrees apart. Odd-sized sleeves (e.g., sleeves 4100 and sleeves 4300) also include one or more lines extending around the circumference of the sleeve above the number markings and / or near the drive end of the sleeve. The inclusion of number markings on all sleeves and one or more lines on odd-sized sleeves reduces the risk of misidentifying adjacent size sleeves (e.g., an 11 mm sleeve and a 12 mm sleeve).

[0061] See also Fig.15A and Fig. 15B, a front view and a rear view of an exemplary sleeve (e.g., sleeve 4300) of the fourth set of sleeves 4000 are shown and described. It should be understood that each of the sleeves 4100, 4200, 4300, and 4400 can include similar features. For example, the sleeve 4300 has an outer surface 4302, a drive end 4304 (similar to the drive end 1304 described above), and a working end 4306 (similar to the drive end 1306 described above). The outer surface 4302 is provided with a first numerical mark 4308, a second numerical mark 4322, and a third numerical mark 4324. In this embodiment, the first numerical mark 4308, the second numerical mark 4322, and the third numerical mark 4324 are separated by about 120 degrees. The outer surface 4302 is also provided with a first line 4314, and the first line 4314 extends around the sleeve circumference above the numerical mark and / or near the drive end 4304. In other words, the first line 4314 is disposed between the driving end 4304 and the first, second, and third digital markers. In another embodiment, the first line can be disposed below the digital markers and / or near the working end 4306. In other words, the first line can be disposed between the working end 4306 and the first, second, and third digital markers.

[0062] Furthermore, as shown, the first numerical marking 4308 includes a first number 4310 and a second number 4312. However, it should be understood that the numerical marking may include less than two numbers (eg, a single number) or more than two numbers, corresponding to the size of the sleeve.

[0063] Each even-sized sleeve in the fourth set of sleeves 4000 also includes three number markings set 120 degrees apart. However, each even-sized sleeve (e.g., sleeve 4200 and sleeve 4400) does not include a line extending circumferentially around the sleeve above the number markings and / or near the drive end of the sleeve.

[0064] See also Fig.16 , an exemplary fifth set of sleeves 5000 of the fifth sleeve set is shown. The fifth set of sleeves 5000 may include sleeves 5100, 5200, 5300, and 5400. As shown, the fifth set of sleeves 5000 is a set of metric sleeves, wherein sleeve 5100 is an 11 mm sleeve, sleeve 5200 is a 12 mm sleeve, sleeve 5300 is a 13 mm sleeve, and sleeve 5400 is a 14 mm sleeve. In addition, although four sleeves are shown for exemplary purposes, the fifth set of sleeves 5000 and / or the fifth sleeve set may include more or less than four sleeves.

[0065] Each of the sleeves 5100, 5200, 5300 and 5400 in the fifth set of sleeves 5000 includes two number marks set 180 degrees apart. Sleeves of odd-numbered sizes (e.g., sleeves 5100 and sleeves 5300) also include a single line extending circumferentially around the corresponding sleeve portion between the two number marks. Sleeves of even-numbered sizes (e.g., sleeves 5200 and sleeves 5400) include a double line extending circumferentially around the corresponding sleeve portion between the two number marks. The inclusion of number marks on all sleeves and the inclusion of a single line on the sleeves of odd-numbered sizes and a double line on the sleeves of even-numbered sizes reduces the risk of misidentifying adjacent size sleeves (e.g., 11 mm sleeves and 12 mm sleeves).

[0066] See also Fig.17A , an exemplary sleeve of the fifth set of sleeves 5000, such as sleeve 5300, is shown and described. It should be understood that each of sleeves 5100, 5200, 5300, and 5400 can include similar features. In this embodiment, sleeve 5300 is substantially the same as sleeve 1300.
