Abstract

(57) [Abstract] (Correction) [PROBLEMS] To obtain a wheel nut that can always fit even one repair tool of a specific size. SOLUTION: A body 1 extends in the axial direction with an appropriate length and has two ends. The screw hole 12 extends axially from one end into the body. Two means for engaging the rotary tool are formed on the outer surface of the body. Each of the means is of a specific size and has a plurality of surfaces 13, 14 for engaging the rotary tool. These surfaces extend axially in an approximately annular manner beyond the outer surface of the body.

[Industrial applications]

 This invention relates to a modified wheel nut. In particular, this invention relates to an improved wheel nut with two different wheel nut dimensions at the same time.

[0002]

[Prior Art and Problems to be Solved by the Invention]

 In FIG. 1, the wheel 90 of the vehicle is assembled by mounting the wheel 90 on the stud 91 of the wheel hub and then screwing the nut 92 onto the stud 91. Currently, there are numerous automobile companies in the world and, therefore, the dimensions of wheel nuts are not yet standardized. In general, wheel nuts on the market come in two different sizes, one is 3/4 inch (or 19 mm) and the other is 13/16 inch (or 21 mm). (According to FIG. 2, the wheel nut is substantially in the shape of a hexahedron and has an axial screw hole extending therein. The length d between the two facing surfaces of the hexahedron is regulated as the dimension of the wheel nut. ). Each car company has its own will in choosing the dimensions of the wheel nuts. In determining the dimensions of wheel nuts, the automobile company provides a set of repair tools, such as spanners, suitable for such dimensions. Repair tools of one particular size cannot be adapted to wheel nuts of other sizes. Therefore, if wheel nuts of different dimensions were used, they could be damaged by using the repair tools provided by the motor vehicle company, especially if the tires of the car were suddenly damaged somewhere along the way. Car owners will not be able to replace tires. This is completely inconvenient for car owners. In addition, it is also necessary for the auto repair center to store two differently sized wheel nuts. In addition, the car repair center will not be able to provide replacement services for car tires with differently sized wheel nuts. Therefore, the fact that the wheel nuts have different dimensions is also difficult for the automobile repair center.

Because of the above deficiencies, the inventor of the present invention has long made efforts to improve wheel nuts.

It is therefore an object of the present invention to provide an improved wheel nut having two different dimensions at the same time.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the wheel nut according to the invention essentially comprises a body. The body is of suitable length and extends axially and thus has two ends. The screw hole extends axially from one end through the body. Two means are formed on the outer surface of the body for engagement with the turning tool. Each of the steps is of a particular size and has a plurality of surfaces for engagement with a turning tool. These planes extend radially beyond the outer surface of the body and form an approximate circle.

Objects and features of the present invention will be apparent from the specification and the drawings. Moreover, this invention is not limited to all the embodiments.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION

 3 and 4, the improved wheel nut according to the invention essentially comprises a body 1. The body 1 extends axially of suitable length and thus has two ends 10 and 11. A screw hole 12 extends axially from the end 10 into the body 1, which screw hole 12 may or may not penetrate the body 1. There is a six-sided surface 13 for engaging the spanner at a position close to the end 10. These six faces 13 are annular and project radially beyond the outer surface of the body 1. The six faces have regular hexagonal (according to FIG. 5) cross sections. The 6-sided 13 combination forms a nut measuring 13/16 inch. Further, there are other six faces 14 for engaging the spanner at a position close to the end 11. The six faces 14 are annular and project radially beyond the outer surface of the body 1. Each face 13 is parallel to the corresponding face 14. The 6-sided 14 combination forms a 3/4 inch nut.

The invention has been described in terms of a preferred embodiment. It will be appreciated that many variations can be made to the preferred embodiments without departing from the scope of the invention, to those of ordinary skill in the art.

【The invention's effect】

 Due to the structure disclosed above, the improved wheel nut according to the present invention simultaneously has two different dimensions. Therefore, repair tools provided by any automobile repair center can be used to assemble and / or disassemble the wheel nut according to the present invention. For example, when using a 3/4 inch sized wrench, tightening and / or loosening of the nut according to the present invention can be accomplished by applying a wrench to face 14 and a 13/16 inch sized wrench. If used, tightening and / or loosening can be achieved by applying a wrench to face 13. This is really useful for car owners, especially in the event of sudden tire damage. In addition, if an automobile repair center uses the wheel nuts of the present invention, it eliminates the need to store two different types of nuts at the repair center. In this way, the wheel nut according to the present invention also simplifies the storage of parts for an automobile repair center.
