Abstract

There is provided a decorative cap for a wheel nut that is easily mounted and fixed to an axle and does not change or be damaged by high-temperature heat transmitted to the axle. A decorative cap is attached to a hybrid nut A of a nut with a washer B screwed to an axle X provided on a wheel of a vehicle body. The enlarged opening chamber 2 is provided, and the enlarged opening chamber 2 is followed by a concave recessed chamber having a regular hexagonal circumferential surface, and a total of twelve engagement heat radiations are provided along two ridge-shaped connecting portions 6 on the adjacent regular hexagonal circumferential surface. Consists of protruding ridges. [Selection] Figure 1

Description

  The present invention relates to a decorative cap for a wheel nut used in automobiles, particularly large vehicles such as trucks and buses.

  Generally, a wheel nut is used for an axle that supports a wheel of an automobile. Hex nuts are used as the wheel nuts, and various nut caps are used to show the exposed hexagon nuts to improve the appearance (for example, see Patent Documents 1 and 2).

  Unlike the complicated configuration described above, it is not simply a hexagon nut, but is vertically fixedly attached to a hybrid nut with a disk-shaped washer movably attached, and is used for covering. The thing of the recent structure which formed the whole by the integral structure is known.

  In this conventional example, a washer attached to the wheel nut cap main body 1a is provided on the opening side of the wheel nut cap main body 1a having a regular hexagonal cross section that can cover the hybrid nut A of the wheel nut with washer screwed to the axle X. B is provided with an enlarged opening chamber 2a to which B can be applied and a recessed chamber 3a, and a protrusion 5a is projected in the longitudinal direction substantially at the center of the regular hexagonal inner peripheral surface 4a of the recessed chamber 3a. The wheel nuts are fitted and fixed to the washer B of the hybrid nut A, and the protrusion 5a is brought into contact with the approximate center of each regular hexagonal outer peripheral surface Aa of the hybrid nut A, and is pushed in and fixed. Yes.

  In the above-mentioned Patent Document 1, a magnet is used and fixed using a magnetic attraction force, and in Patent Document 2, it is formed using a complicated structure, both of which are expensive and cannot be provided at a low cost. Was not put to practical use.

  In addition, the structure shown in FIG. 4 is simple in structure, but heat transmitted to the hybrid nut A of the wheel nut is directly applied, and heat cannot be effectively radiated from the base P of the protrusion 5a of the wheel nut cap body 1a. There was a disadvantage that the wheel nut cap body 1a was deformed or damaged by heat.

  This device can solve the above-mentioned problems by having the following configuration.

  (1) A decorative cap that is attached to a hybrid nut of a nut with a washer that is screwed to an axle provided on a wheel of a vehicle body, and an enlarged opening chamber is provided in an opening portion of a cylindrical cap provided with a head. In addition to this enlarged opening chamber, a regular hexagonal circumferential surface has a recessed chamber, and a total of 12 engaging heat radiation projections are projected along the angled connecting portion of the adjacent regular hexagonal circumferential surface. A decorative cap for wheel nuts characterized by comprising

  (2) The decorative cap for wheel nuts according to (1) above, wherein the head has a decorative pattern.

  According to the present invention, the opening portion of the cylindrical cap is formed as an enlarged opening chamber, and the twelve protrusions are juxtaposed as a mountain-shaped connecting portion, so that the peripheral surface of the washer and the surface of the hybrid nut A are provided. Since it can be reliably engaged and attached, and the high temperature released from the axle can be smoothly radiated, the risk of deformation breakage due to heat can also be avoided.

It shows a conventional example, (a) a side view in use, (b) a partial side view of (a), (c) (b) BB cross-sectional view

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  Examples of the present invention will be described below.

  Reference numeral 1 denotes a wheel nut cap body that can be attached to a hybrid nut A of a wheel nut with a washer that is screwed to the axle X of the vehicle body, 2 is an enlarged opening chamber of the wheel nut cap body 1, and 3 is an enlarged opening chamber 2 Is a recessed chamber that is provided with a regular hexagonal inner peripheral surface 4 and a total of twelve engagement heat radiations, two on each side, along the mountain-shaped connection portion 6 at the bent portion of the adjacent regular hexagonal inner peripheral surface 4. A protruding ridge 5 is provided.

  A wheel nut cap main body 1 having a head portion 7 as a whole is formed. A decorative pattern 8 shown by the manufacturer is formed on the head portion 7 and is molded with a synthetic resin material such as ABS resin. A metal-like glossy surface is formed to express aesthetics. The cylindrical wheel nut cap body 1 is pushed into a hybrid nut A of a wheel nut in which the enlarged opening chamber 2 is screwed to the axle X, and the enlarged opening chamber 2 is covered with a washer B of the hybrid nut A. At the same time, it is engaged by engaging twelve protrusions 5 in total along the angled connection 6 of the recessed chamber 3 across the hexagonal angle Ab of the hybrid nut A of the wheel nut. Can be attached.

  In this way, the decorative nut attached to the hybrid nut A of the wheel nut has a high heat quantity of about 100 degrees Celsius transmitted into the hybrid nut A of the wheel nut. Since heat transfer is dispersed even if the heat is absorbed from 5, the base P of the ridge 5 of the cylindrical wheel nut cap body 1 is not beautifully welded or thermally deformed and further deformed and damaged at all times. The vehicle can be driven while maintaining the state.
