  The anchor plate 22 has three arm portions.

  The mount 8 is configured in a dish shape with a wide edge portion, and a plurality of through holes are opened in the edge portion in order to fix a wheel bolt for coupling the wheel and the stationary wheel cover. Further, a through hole 28 for bearing connection for the center bolt 26 for fixing the bearing holder 10 and the mount 8 is opened at the bottom portion of the dish-shaped mount 8. The rim of the mount 8 is provided with a folded rim on the outermost periphery.

  As shown in FIG. 4, the bearing joining through-hole 28 is tapered at its end face. On the other hand, a taper is also formed on the screw head of the center bolt 26, and the taper angle of the center bolt 26 is set larger than the taper angle of the bearing joining through hole 28. With such a configuration, the center of the center bolt 26 is automatically aligned so that it is always set at the center of the bearing joining through hole 28. In order to always set the center of the through hole 28 for bearing connection, it is within the scope of design change to use a threaded rod and a tapered nut having a taper on the side surface instead of the center bolt.

  The bearing portion 14 includes a cylindrical center spacer 30 adjacent to the mount 8, a center bolt spring lock washer 32 serving as a locking washer adjacent to the center spacer 30, and a disk board on the outer periphery of the center spacer 30. A stopper lever 16 that is a lever for fixing 24 to the anchor plate 22 is disposed.

  The stopper lever 16 is screwed and fixed to a plate-shaped bearing cover 36, and the bearing 12 and the locating snap ring 38 are inserted between the bearing cover 36 and the anchor plate 22.

  The stopper lever 16 is a lever used when the anchor plate 22 is rotated to be attached to the disk board 24 and when the anchor plate 22 is attached / detached.

  As shown in FIG. 7, the stopper lever 16 can take a plurality of forms according to the size of the tire. In FIG. 7A, the coupling portion with the anchor plate 22 is composed of a single circular through-hole 62 and an outer peripheral portion 60, and its fulcrum is located at the center of the stationary wheel cover 2 of the present invention. Stabilize. In this case, it is not possible to deal with a plurality of sizes of disc covers exceeding the extension length of the stop lever.

  In FIG. 7B, the joint portion with the anchor plate 22 is opened so that the two circular through-holes 66 and 68 overlap each other, and the outer peripheral portion 64 is also configured to surround the through-holes 66 and 68 in an 8-shape. Is done. Two different sizes of disk boards can be accommodated.

  In FIG. 7C, the stopper lever 16 having three through holes is further arranged, and the through holes 70, 72 and 74 are arranged. It can support 3 size disk boards. These through holes 70, 72, 74 are configured to surround the outer peripheral portion 76.

  According to FIG. 2, the grip 34 is provided on the side opposite to the coupling portion of the stopper lever 16. Since the length of the stopper lever 16 is changed depending on the size of the tire and the wheel, the grip 34 is always positioned on the outer peripheral portion of the disk board, and the length is changed by the sliding movement of the grip 34.

  Further, the grip 34 is sandwiched and fixed between a pair of grip engaging portions 58 projecting from the back surface of the disc board 24 of the stationary wheel cover 2. On the contrary, when replacing the disk board, the grip 34 is released from the gripping of the grip engaging portion 58.

  The grip 34 includes a grip projecting portion 35. Since the grip projecting portion 35 contacts the back surface of the disk board 24, the entire grip 34 is prevented from contacting the back surface of the disk board 24, thereby improving operability.

  A bearing holder 10 for screwing the center bolt 26 is inserted into the inner periphery of the bearing 12. The center bolt 26 passes through the center of the bearing portion 14 including the bearing holder 10 from the mount 8 described above.

  The center bolt 26 is fixed to the center spacer 30, the center bolt spring lock washer 32, and the bearing holder 10 and rotates together with the inner ring of the bearing 12.

  On the other hand, since the bearing cover 36, the outer ring of the bearing 12, the anchor plate 22 and the disc board 24 are integrated, these disc boards 24 are prevented from rotating (FIG. 3).

  The anchor plate 22 is provided with an opening 40 having a diameter larger than that of the inner ring of the bearing 12 at the center, and a step 42 on the outer periphery of the opening 40 where the outer ring of the bearing 12 is locked.

The anchor plate 22 is engaged with and coupled to the disk board 24. Since the arm portion 18 and the connecting portion 20 are space between each other, the mount 8 can be fixed with screws without removing the anchor plate 22 (FIG. 5A). Further, in the anchor plate 22, the presence of the connecting portion 20 makes it possible to reduce the center of gravity of the anchor plate 22 and the disk board 24 and to stop the rotation of the disk board 24 without adding any parts. .

  The disk board 24 is a disk-shaped disk having ribs 46 provided at the ends, and a notch 50 is provided at one end of the disk board 24 to allow airflow to pass therethrough. The surface of the disk board 24 is made of metal or resin to form a flat surface.

  On the other hand, a rib 48 having a honeycomb structure is provided on the entire back surface of the disk board 24 except for a part thereof. By adopting this honeycomb structure, the strength of the disk board 24 is improved, so that the thinning can be easily adopted (FIG. 4).

  Furthermore, when the notches 50 are arranged horizontally in the horizontal direction, anchor plate arrangement portions 52 that do not provide a honeycomb structure radially in six directions from the center of the disk board 24 are provided. The anchor plate placement portion 52 is pressed downward to a position corresponding to the opening 44 at the end of the anchor plate 22 when the arm portion 18 of the anchor plate 22 is mounted upward and when mounted downward. The disk board 24 protrudes from the back surface, is bent in the center direction, and has a horizontal portion protruding in the horizontal direction. A hemispherical downward pressing portion is provided from the horizontal portion 55 toward the disk board 24. In addition, an opening space 57 is provided on the side.

  In addition, a rib 56 for rectifying the airflow from a part of the circumference to the notch is provided in a part of the rib 48 of the honeycomb structure of the disk board 24.

  Further, a grip locking portion 58 for locking the grip 34 of the stopper lever 16 is provided in the vicinity of the notch 50 on the back surface of the disk board 24.

  Next, the operation of the stationary wheel cover 2 according to the present invention will be described with reference to FIGS. First, the bearing holder 10 is inserted into the bearing 12 and fixed with the locating snap ring 38. This is sandwiched between the anchor plate 22 and the bearing cover 36, and the stopper lever 16 is overlapped and fixed with screws at positions corresponding to the four corners of the bearing cover 36.

  The mount 8, the center spacer 30, and the center bolt spring lock washer 32 are overlapped with each other and fixed with the bearing holder 10 through the center bolt 26. As a result, the anchor plate 22 is integrated from the mount 8.

  In this state, the mount 8 is fixed to the wheel 6 with a wheel bolt as shown in FIGS. 5 (a), 5 (b) and FIG. At this time, as shown in FIG. 5A, it is clear that the wheel bolt of the mount 8 has little interference with the arm 18 of the anchor plate 22, and the bolt can be easily screwed. Up to the anchor plate 22 is fixed to the wheel 6 by screwing the wheel bolt.

  Next, the opening 44 of the anchor plate 22 is overlapped with the opening space 57 of the disk board 24 so as to coincide with each other, and the disk board 24 is rotated to the right with the center as an axis. And is fixed to the hemispherical downward pressing portion. Here, even if the disk board 24 is rotating, it returns so that the connection part 20 of the anchor plate 22 becomes a vertically lower part. Further, the notch 50 of the disk board 24 is always set to be opposite to the traveling direction.

  When the vehicle is run in this state, an air flow is generated between the disk board 24 and the tire 5 or the wheel 6, but both are rectified by the rib 56 for rectifying the air flow, and the air flow flows from the notch 50. Further, since the rotation of the wheel due to the traveling of the automobile is blocked by the bearing 12, the disk board 24 always stops so that the notch 50 is in the direction opposite to the traveling direction.

  With the above configuration, the movable-side fixture connected to the stationary wheel cover side can work without fixing the fixed-side fixture connected to the wheel side, i.e., the mount. Become.

  Furthermore, each part fulfills a plurality of functions, thereby simplifying the structure, reducing the number of parts and reducing the manufacturing cost.

  In addition, by adopting the honeycomb rib structure, it is possible to increase the strength while being thin.

  In the first embodiment, the five-hole mount 8 has been described. Of course, the metal fittings of the device need to be changed depending on the wheel and the vehicle type. A mount that can be used instead of the mount 8 is shown in FIGS. In particular, the mount may have 6 holes, and various mounts can be used, as shown in FIGS. 8 and 9 show a two-hole mount, and FIGS. 10, 11 and 12 show a three-hole mount and an arm type is adopted. Although FIG. 13 also has three holes, the shape of the center indicating portion is circular. 14 and 15 show mounts for a large number of holes. FIG. 14 shows a 5-hole mount, and FIG. 15 shows a 6-hole mount. FIG. 16 shows an embodiment in which the stationary wheel cover 2 of the present invention is applied to the front and rear wheels of an automobile.

  In addition, about the moving body, although it demonstrated centering on the motor vehicle in Example 1 and 2, if it has a wheel, it will not be limited only to a motor vehicle, passenger cars, taxis, etc. Commercial vehicles such as buses and trucks are generally used, but naturally include bicycles, tricycles, light vehicles such as wheelchairs and rear cars, motorized bicycles, and two-wheeled vehicles. Furthermore, it goes without saying that any “wheel” of a moving body with wheels, such as a three-wheel motorcycle for transportation such as pizza delivery, golf cart, stroller, Segway (registered trademark), tourist rickshaw, etc. Absent.

  By adopting the stationary wheel cover 2 according to the present invention, the outer shape of the wheel 6 is flattened, thereby preventing an accident caused by the unevenness of the wheel.

  In addition, it is easy to attach and detach, and the stationary wheel cover 2 having many flat portions can be sufficiently utilized for advertisement.
