Each screw stud 22 includes a fixing portion 22a and a screw portion 22b. The fixed portion 22a extends into the opening of the axle hub 20 and is fixedly attached to the axle hub 20 by press-fitting engagement. Since the axle hub 20, the screw stud 22, and the press-fitting engagement are features of a conventional vehicle, a detailed description thereof will be omitted for the sake of brevity.

The wheel 10 is an annular metal structure on which rubber tires are mounted. The wheel 10 includes a central hub mounting portion that includes a plurality of mounting holes 26 and a plurality of recesses 28 that are arranged coaxially with the mounting holes 26 and communicate with the mounting holes 26. Since the wheel 10 and the tire are conventional components of a vehicle, the detailed description thereof is omitted for the sake of brevity.

Hereinafter, the wheel lock assembly 16A (16) according to the first embodiment will be specifically described with reference to FIGS. The wheel lock assembly 16A basically includes a main body 34 (FIGS. 2 to 10, 14 to 15), an inner sleeve 36 (cover) (FIGS. 2, 4 to 5, FIGS. 7 to 8, and 11). , Outer sleeve 38 (cover) (FIGS. 2-8, 12), and key 40 (FIGS. 7, 14, 15).

7, 9, and 10, the main body 34 is illustrated as being removed from the other parts of the wheel lock assembly 16 </ b> A. The main body 34 has a central axis A1 passing through the inside. The main body 34 is basically an annular hollow member, and is opposite to the wheel engagement end 44 (wheel contact end), the outer sleeve support region 46, the key portion 48, the inner sleeve support region 50, and the wheel engagement end 44. Has a key receiving end 52 (wheel non-contact end). A screw hole 54 provided with a stud engaging screw groove with which the screw portion 22 b of the screw stud 22 is engaged extends from the wheel engaging end 44 in the main body 34 to the key receiving end 52. The main body 34 can be attached to and detached from the axle hub 20 by moving in the twisting direction (in this embodiment, the direction around the central axis A1 of the main body 34).

The wheel engagement end 44 is configured to come into contact with the wheel 10 and to fix and hold the wheel 10 to the axle hub 20. More specifically, the wheel engagement end 44 has a conical or tapered portion 44a (tapered surface) and a cylindrical portion 44b. As shown in FIG. 9, the outer surface of the cylindrical portion 44b has an outer diameter of the first diameter D1. When the wheel lock assembly 16 </ b> A is mounted on the vehicle 12, the screw stud 22 is screwed into the screw hole 54. When the wheel lock assembly 16 </ b> A is fastened to the screw stud 22, the tapered portion 44 a of the wheel engagement end 44 contacts the surface of the wheel 10 in the recess 28 surrounding the mounting hole 26, as shown in FIG. 2.

The outer sleeve support region 46 is defined on the outer surface of the main body 34 between the cylindrical portion 44 b of the wheel engagement end 44 and the key portion 48. The outer sleeve support region 46 includes an annular concave surface 46a, an outer annular projection 46b, and an inclined surface 46c. As shown in FIG. 9, the annular concave surface 46a has an outer diameter of the second diameter D2, and the outer annular protrusion 46b has an outer diameter of a third diameter D3 larger than the second diameter D2. The second diameter D2 and the third diameter D3 are both smaller than the first diameter D1.

The key portion 48 is provided on the outer periphery of the main body 34 and includes, for example,

surface contours

48a and 48b as shown in FIG. 9 as surface contours (first surface contours) that define the first key pattern 48c. FIG. 9 shows only two types of

surface contours

48a and 48b having different sizes. However, it should be understood from the drawings and the description of the present specification that more surface contours having different sizes and shapes can be provided in the key portion 48. The first key pattern 48c may be defined by a plurality of surface contours 48a, a plurality of surface contours 48b, and a plurality of other surface contours (not shown). The first key pattern 48c is configured to engage with the second key pattern 62d of the key 40, which will be described in detail below, and the main body 34 moves in the torsional direction by the movement of the engaged key 40 in the torsional direction. It is supposed to be. That is, the 1st key pattern 48c is comprised so that the main body 34 may be connected with the tool for moving to a twist direction. This tool serves as means for mounting and removing the wheel lock assembly 16A. The tool includes a key 40 and a wrench that engages with the key 40. In the present embodiment, an example in which the main body 34 is moved in the twisting direction using a wrench or the like together with the key 40 is shown, but the present invention is not limited to this. For example, the key 40 may be a key (tool) integrated with a wrench. In this case, the main body 34 can be moved in the twisting direction only by this key. As shown in FIGS. 9 and 10, the key portion 48 as a whole has an outer diameter substantially the same as the second diameter D2. As shown in FIG. 10, the

surface contours

48 a and 48 b can be formed from an uneven surface and a non-uneven surface that reduce the overall diameter of the key portion 48. Note that the first key pattern 48c can be defined by combining the

surface contours

48a and 48b in different orders and further combining other surface contours in various forms, or omitting other surface contours. And should be understood from the description herein.

The inner sleeve support region 50 includes an annular concave surface 50a, an outer annular projection 50b, and an inclined surface 50c. The annular concave surface 50a has a fourth diameter D4, and the outer annular projection 50b has a fifth diameter D5. The fifth diameter D5 is larger than the fourth diameter D4. Further, the fifth diameter D5 is smaller than the second diameter D2. The inclined surface 50c of the inner sleeve support region 50 decreases in diameter as it advances from the outer annular protrusion 50b toward the key receiving end 52 along the axial direction of the main body 34. It should be understood from the drawings and the description of the present specification that the axial direction of the main body 34 is coaxial with the main body 34 or parallel to the central axis A1. Therefore, as a whole, the overall diameter of the main body 34 decreases along the axial direction from the cylindrical portion 44b of the wheel engagement end 44 toward the key receiving end 52 side.

Hereinafter, the inner sleeve support region 50 is also referred to as a first support region, and the outer sleeve support region 46 is also referred to as a second support region.

The key receiving end 52 (also called a wheel non-contact end or a free end of the main body) is cylindrical and has an outer diameter smaller than the fifth diameter D5. The outer diameter may be greater than or equal to the fourth diameter D4.

The screw hole 54 extends from the wheel engagement end 44 to the key receiving end 52 so as to completely penetrate the main body 34. However, the screw hole 54 only needs to be open at the wheel engagement end 44 so that the screw groove of the screw hole 54 can contact and engage the screw groove of the stud 22. Should be understood from. For this reason, as another embodiment, the screw hole 54 can be extended to the middle of the main body 34 to close the key receiving end 52 of the main body 34.

7 and 11, the inner sleeve 36 (first sleeve) is illustrated as being removed from the other part of the wheel lock assembly 16A. As shown in FIG. 11, the inner sleeve 36 is a hollow cap-shaped member, and has an annular main body portion 36a, an end cap portion 36b that is an end cover, an inner surface 36c, an inner annular protrusion 36d, and an open end 36e. The inner surface 36c has a sixth diameter D6, and the inner annular protrusion 36d has an inner diameter of a seventh diameter D7 that is smaller than the sixth diameter D6. The seventh diameter D7 is smaller than the fifth diameter D5 of the outer annular protrusion 50b of the inner sleeve support region 50 of the main body 34 and slightly larger than the fourth diameter D4 of the annular concave surface 50a. The sixth diameter D6 is slightly larger than the fifth diameter D5 of the outer annular protrusion 50b of the inner sleeve support region 50 of the main body 34. The annular main body 36a of the inner sleeve 36 has a cylindrical outer surface having an eighth diameter D8. The eighth diameter D8 is smaller than the second diameter D2 of the annular concave surface 46a and the key portion 48. Therefore, when the inner sleeve 36 is attached to the main body 34, the outer diameter of the inner sleeve 36 is smaller than the outer diameter of the key portion 48. Therefore, as will be described later, the inner sleeve 36 becomes an obstacle to the insertion of the key 40. Instead, the key 40 can contact and engage the key portion 48.

8, 14 and 15, the end cap portion 36b (closed end) of the inner sleeve 36 covers the screw hole 54 (center hole) at the key receiving end 52 of the main body 34.

The inner sleeve 36 can be attached to the inner sleeve support region 50 by various assembling methods. The inner sleeve 36 can be press-fitted onto the inner sleeve support region 50 by using the inclined surface 50c as means for moving the outer annular protrusion 50b and the end cap portion 36b while applying pressure to each other during mounting. As another method or a combination with the above-described method, the inner sleeve 36 can be fitted into the main body 34 in a more free state by heating the inner sleeve 36 to expand the entire diameter. When the temperature decreases, the inner sleeve 36 is reduced in diameter. When the inner annular protrusion 36d is pushed and exceeds the outer annular protrusion 50b, the inner sleeve 36 can rotate about the main body 34, and the main body 34 is interfered with by the inner annular protrusion 36d, the outer annular protrusion 50b, and the key portion 48. The inner annular protrusion 36d is held by the outer annular protrusion 50b so as to prevent the movement in the axial direction. This interference is due to the relatively different diameters of adjacent surfaces of the body 34.

Specifically, as shown in FIG. 10, the main body 34 includes a first shoulder surface 34a and a second shoulder surface 34b that are perpendicular to the central axis A1 of the main body 34, respectively. The first shoulder surface 34 a extends from the key portion 48 to the annular concave surface 50 a of the inner sleeve support region 50 in the circumferential direction of the main body 34. Similarly, the second shoulder surface 34 b extends from the cylindrical portion 44 b of the wheel engagement end 44 to the annular concave surface 46 a of the outer sleeve support region 46 in the circumferential direction of the main body 34. In a state where the inner sleeve 36 is attached to the inner sleeve support region 50, the open end 36e of the inner sleeve 36 faces the first shoulder surface 34a. Accordingly, the first shoulder surface 34a prevents the inner sleeve 36 from moving toward the wheel engaging end 44 side of the main body 34 along the axis A1. Since the fifth diameter D5 of the outer annular protrusion 50b is larger than the seventh diameter D7 of the inner annular protrusion 36d, the inner sleeve 36 moves toward the key receiving end 52 side of the main body 34 along the axis A1 by the outer annular protrusion 50b. It is prevented. For this reason, the axial movement of the inner sleeve 36 is prevented. On the other hand, the inner sleeve 36 rotates freely around the main body 34.

7 and 12 show the outer sleeve 38 (also referred to as a second sleeve) in a state where it is removed from the other part of the wheel lock assembly 16A. As shown in FIG. 12, the outer sleeve 38 is a hollow cylindrical member having both ends opened, and an annular main body portion having a first opening end 38b, an inner surface 38c, an inner annular protrusion 38d, and a second opening end 38e. 38a. The inner surface 38c has a ninth diameter D9, and the inner annular protrusion 38d has a tenth diameter D10 that is smaller than the ninth diameter D9. The tenth diameter D10 is smaller than the third diameter D3 of the outer annular protrusion 46b of the outer sleeve support region 46 of the main body 34 and slightly larger than the second diameter D2 of the annular concave surface 46a. The ninth diameter D9 is slightly larger than the third diameter D3 of the outer annular protrusion 46b of the outer sleeve support region 46 of the main body 34. The annular main body 38a of the outer sleeve 38 has a cylindrical outer surface having an eleventh diameter D11. The eleventh diameter D11 is substantially the same as the first diameter D1 of the cylindrical portion 44b of the wheel engaging end 44 of the main body 34 within a predetermined allowable range. Therefore, as shown in FIGS. 2 and 14, the outer sleeve 38 has an outer diameter that is substantially the same as the outer diameter of the cylindrical portion 44 b of the wheel engaging end 44 of the main body 34.

The outer sleeve 38 can be attached to the outer sleeve support region 46 by various assembling methods. For example, the outer sleeve 38 can be press-fitted onto the outer sleeve support region 46 using the inclined surface 46c as a means for reducing interference between the outer annular projection 46b and the inner annular projection 38d during mounting. As another method or a combination thereof, the outer sleeve 38 can be fitted into the main body 34 in a more free state by heating the outer sleeve 38 to expand the diameter of the outer sleeve 38 as a whole. As the temperature decreases, the outer sleeve 38 shrinks. When the inner annular protrusion 38d is pushed and exceeds the outer annular protrusion 46b, the outer sleeve 38 can rotate around the main body 34, and the inner annular protrusion 38d, the outer annular protrusion 46b, and the cylindrical portion 44b of the wheel engaging end 44 are provided. The inner annular protrusion 38d is held by the outer annular protrusion 46b so that the movement of the main body 34 in the axial direction is prevented by the interference with the outer annular protrusion 46b. This interference is due to the relatively different diameters of adjacent surfaces of the body 34.

When the outer sleeve 38 is attached to the outer sleeve support region 46, the second open end 38e of the outer sleeve 38 faces the second shoulder surface 34b. Therefore, the second shoulder surface 34b prevents the outer sleeve 38 from moving toward the wheel engagement end 44 side of the main body 34 along the axis A1. Since the third diameter D3 of the outer annular protrusion 46b is larger than the tenth diameter D10 of the inner annular protrusion 38d, the outer annular protrusion 46b causes the outer sleeve 38 to move in the axial direction (along the axis A1). Moving to the 52 side is prevented. For this reason, the axial movement of the outer sleeve 38 is prevented. On the other hand, the outer sleeve 38 is freely rotatable about the main body 34 and the inner sleeve 36 (around the axis A1).

As shown in FIGS. 8, 14, and 15, the outer sleeve 38 covers the radially outer surface of the inner sleeve 36 while leaving a gap Gp (key receiving gap). Further, as shown in FIG. 8, the inner sleeve 36 (first sleeve) has a first length L1 measured along the axial direction of the main body 34, and the outer sleeve 38 (second sleeve) has a main body. 34 has a second length L2 measured along the axial direction. The second length L2 is longer than the first length L1.

7, 13, 14, and 15 show the key 40. The key 40 has a tool receiving portion 60 and a key sleeve 62. The tool receiving portion 60 is illustrated in a general hexagonal shape with a plurality of surfaces, and can be engaged with a tool such as a box wrench or other wrench to attach and detach the wheel lock assembly 16A. However, it should be understood from the drawings and the description herein that the tool receiver 60 can include other tool receiver shapes. The key sleeve 62 of the key 40 includes a hollow inner surface 62a having

surface contours

62b and 62c (second surface contours) that define a second key pattern 62d. The second key pattern 62d has a shape such that when the key sleeve 62 of the key 40 is inserted on the inner sleeve 36, the key receiving end 52, and the key portion 48, the first key pattern 48c is engaged with and engaged with the first key pattern 48c. Have dimensions. Specifically, as shown in FIG. 14, the key sleeve 62 has an inner surface having a twelfth diameter D12 and an outer surface having a thirteenth diameter D13. The diameter D12 is slightly larger than the eighth diameter D8 of the inner sleeve 36, and the diameter D13 is slightly smaller than the ninth diameter D9 of the outer sleeve 38.

As shown in FIG. 14, the gap Gp is defined between the outer surface of the inner sleeve 36 and the inner surface of the outer sleeve 38. For this reason, the gap Gp is approximately half the value obtained by subtracting the eighth diameter D8 of the inner sleeve 36 from the ninth diameter D9 of the outer sleeve 38. That is, the gap Gp is a distance from the inner surface of the outer sleeve 38 to the outer surface of the inner sleeve 36. As shown in FIG. 15, the total thickness T1 of the key sleeve 62 is slightly smaller than the gap Gp so that the key sleeve 62 of the key 40 can be easily inserted into the gap Gp. When the key sleeve 62 is inserted into the gap Gp in the wheel lock assembly 16A, the second key pattern 62d contacts the first key pattern 48c and engages and engages in a matched state. As shown in FIG. 15, in the state where the key 40 is mounted on the wheel lock assembly 16A, the wheel lock assembly 16A can be mounted on and removed from the vehicle 12 by using a wrench or other torque generating tool.

The configuration and design of the wheel lock assembly 16A realizes various features. First, it is difficult to provide torque to loosen the wheel lock assembly 16 because the outer sleeve 38 is free to rotate about the body 34. For example, if one person attempts to remove the wheel lock assembly 16A by applying pressure to the outer sleeve 38 for improper purposes, the outer sleeve 38 will rotate freely about the body 34. Further, even if the outer sleeve 38 is rotated in a state in which the outer sleeve 38 is deformed in any form and in contact with the inner sleeve 36, the inner sleeve 36 is also freely rotated with respect to the main body 34.

Second, if one person attempts to weld an extension to the free end (key receiving end 52) of the wheel lock assembly 16A for fraudulent purposes, the inner sleeve 36 prevents the attempt. Specifically, the inner sleeve 36 includes an end cap portion 36b that completely covers the key receiving end 52 of the body 34 of the wheel lock assembly 16A. Even if a tool or an extension that receives the tool is welded to the inner sleeve 36 by an unauthorized welding action, the unauthorized action is prevented because the extension that receives the tool and the inner sleeve 36 rotate freely with respect to the main body 34. .

Third, since the wheel lock assembly 16A includes both the inner sleeve 36 and the outer sleeve 38, the first key pattern 48c is hidden in a recessed area. Specifically, the inner sleeve 36 covers the key receiving end 52 of the main body 34. The first key pattern 48 c needs to be separated from the key receiving end 52 by the amount of the inner sleeve 36. For this reason, it is not easy to access the first key pattern 48c and to cheat on the first key pattern 48c. Further, since the outer sleeve 38 covers the first key pattern 48c and the inner sleeve 36, the first key pattern 48c is further protected and access to the first key pattern 48c is prevented. Therefore, the key sleeve 62 is provided with a length corresponding to the length of the gap Gp in the axial direction. That is, when the key sleeve 62 is inserted into the gap Gp between the inner sleeve 36 and the outer sleeve 38, the second key pattern 62d of the key sleeve 62 of the key 40 is It is long enough to contact and engage the one key pattern 48c. More specifically, the key 40 includes a second key pattern 62d that engages with the first key pattern 48c when the key 40 is inserted over the first sleeve 36, the key receiving end 52 of the main body 34, and the key portion 48. The inside of the containing key sleeve 62 includes a hollow inner surface.

As the key 40D is moved further into the wheel lock assembly 16D, the second key pattern 62d engages with the first key pattern 48c and the fourth key pattern 62Dd engages with the third key pattern 36Dk.

In addition, if the first key pattern 48c and the third key pattern 36Dk are different in diameter so that the overall diameter of the third key pattern 36Dk is smaller than that of the first key pattern 48c, they are completely different patterns. It is also possible to do. In this case, the second key pattern 62d can pass through the third key pattern 36Dk without interference. Then, when the second key pattern 62d is engaged with the first key pattern 48c, the fourth key pattern 62Dd can be engaged with the third key pattern 36Dk.

Hereinafter, the wheel lock assembly 16E (16) according to the fifth embodiment will be described with reference to FIGS. Since the first and fifth embodiments are similar, the same reference numerals as those in the first embodiment are assigned to the same portions in the fifth embodiment as those in the first embodiment. Further, in consideration of simplicity, the description of the same parts as those of the first embodiment in the fifth embodiment is omitted.

In the fifth embodiment, the wheel lock assembly 16E includes a main body 34E similar to the main body 34 of the wheel lock assembly 16A of the first embodiment.

The main body 134 includes a wheel engagement end 144 (wheel contact end), a sleeve support region 146, a cylindrical portion 148, a key receiving end 152 (wheel non-contact end), and a key portion 190. Each of the wheel engagement end 144, the sleeve support region 146, the cylindrical portion 148, and the key receiving end 152 has an annular overall shape centering on the central axis A <b> 1 of the main body 134. As shown in FIG. 27, the wheel engagement end 144 can include a tapered portion 144a (tapered surface) and a cylindrical portion 144b. As shown in FIG. 32, the cylindrical portion 144b of the wheel engagement end 144 has an outer diameter D14. The wheel engagement end 144 includes a screw hole 154 that opens at the wheel engagement end 144 and extends partway in the main body 134. The screw hole 154 is provided with a stud engagement screw groove with which the screw portion 22b of the screw stud 22 is engaged. The screw hole 154 is provided by machining or the like so as to engage with the screw portion 22 b of the screw stud 22. The main body 134 can be attached to and detached from the axle hub 20 by moving in the twisting direction (in this embodiment, the direction around the central axis A1 of the main body 134).

The sleeve support region 146 of the main body 134 includes an annular concave surface 146a, an annular projection 146b, and an inclined surface 146c. The annular concave surface 146a has an outer diameter D15, and the annular protrusion 146b has an outer diameter D16. As will be described in detail below, the outer diameter D16 is larger than the outer diameter D15 in order to hold the covering sleeve 136. The inclined surface 146c has an outer diameter that gradually decreases from the outer diameter D16 toward the key receiving end 152 side.

The cylindrical portion 148 has an outer diameter D17 that is substantially the same as the outer diameter D15. However, as will be described later, the outer diameter D17 may be any diameter as long as the outer diameter D17 is smaller than the outer diameter D16 and the inclined surface 146c is set so as to assist the wearing of the covering sleeve 136.

As shown in FIG. 32, the covering sleeve 136 includes an end cap portion 136b (first end) which is an end cover, an annular inner surface 136c, an inner annular protrusion 136d, and an annular main body portion 136a having an open end 136e (second end).
