Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a pointer structure of a pointer meter.

[Conventional technology]

Conventional guide structures of this type are shown in Figures 7 and 8.
The one shown in the figure is known.

In the case of this conventional structure, the upper surface of the mounting base 2 to be attached to the pointer shaft 1 is formed as a flat surface 3, a projection 4 and a hole 5 are formed in this flat surface 3, and a corresponding engagement is formed in the pointer body 6. A protrusion 7 and an engagement hole 8 are formed, and the pointer main body 6 is attached to the mounting base 2 by means of the protrusion 4 and the engagement hole 8, and the engagement protrusion 7 and the hole 5.

By the way, the mounting base 2 is usually made of a dark-colored resin such as black, while the pointer body 6 is made of white or other dark-colored resin.
It is made of brightly colored resin such as orange.

This is to make the pointer body 6 stand out and easy to see by making it brightly colored.

[The problem that the idea aims to solve]

However, as a result of this structure, the mounting base 2
At the contact portion between the pointer body 6 and the pointer body 6, the black color of the mounting base 2 may be visible through the pointer body 6. This means that if the cross-sectional shape of the base of the pointer main body 6 becomes thinner toward the left and right edges 9, for example, a triangular cross-section, the left and right edges 9
However, if the edge angle is acute and the wall is quite thin, burrs are more likely to occur, and the more the left and right edges 9 have an edge shape, the more likely burrs will occur.As a result, the base of the pointer body 6 may appear darkened or burrs may be visible. As a result, the color tone of the pointer main body 6 may be lost or burrs may be visible, resulting in the inconvenience that the appearance of the pointer is impaired.

[Means to solve the problem]

The purpose of the present invention is to eliminate these inconveniences, and as shown in the attached drawings, the gist of the invention is to include a mounting base that is attached to the pointer shaft, a mounting base that is disposed on this mounting base, and a structure that is approximately similar to the pointer shaft. In a pointer consisting of a pointer body that extends in a perpendicular direction, the cross-sectional shape of the base of the pointer body that contacts the mounting base becomes thinner toward the left and right edges, and the mounting base is dark colored. The pointer body is formed of a light-colored resin, the mounting base and the pointer body are integrally molded in two colors, and the lower part of the base of the pointer body is embedded in the upper end of the mounting base. It has a guideline structure that is characterized by being configured to

〔Example〕

1 to 6 illustrate embodiments of the present invention,
1 to 4 show a first embodiment, and FIGS. 5 and 6 show a second embodiment.

Incidentally, the same reference numerals are given to the same parts as those of the above-mentioned conventional structure.

The first embodiment shown in FIGS. 1 to 4 shows an indicating instrument for an automobile, and a case 10 includes an instrument body 1.
1 is installed inside the instrument, a pointer shaft 1 is provided protruding from the instrument body 11, and a dial plate 12 is attached, so that the characters, scales, etc. on the dial plate 12 are indicated by the pointer.

In this case, first, the mounting base 2 is formed of dark-colored resin, and at this time, the fitting groove 13, the protrusion 4, and the hole 5 are formed, and the mounting base 2 is placed in a mold and left in that state. The pointer body 6 is molded in two colors integrally with the mounting base 2 by pouring light-colored molten resin which is the material of the pointer body 6.

Since this first embodiment has the above configuration, the lower part of the base of the pointer main body 6 is embedded in the mounting base 2 by the fitting groove 13, and as a result, the pointer main body 6
Even if the cross-sectional shape of the base becomes thinner toward the left and right edges 9, the left and right edges 9, which are considerably thinner, are buried in the mounting base 2 and placed under the light-colored resin. Because it is hidden, there is no darkening near the bottom of the base of the pointer body 6, and no burrs are visible.
The color tone of the pointer body 6 is improved, and the pointer body 6 can be recognized by its clean appearance. By integrally molding the pointer body 6 and the mounting base 2 in two colors, the dimensional accuracy of each part is maintained stably. It is also possible to
The weight balance of the entire pointer can also be stabilized.

The second embodiment shown in FIGS. 5 and 6 shows a different structure, in which the pointer body 6 is first formed of light-colored resin to have a substantially equilateral triangular cross section, and the pointer body 6 is
is placed in a mold, and in that state, dark-colored resin, which is the material of the mounting base 2, is poured in, and the mounting base 2 is molded in two colors integrally with the pointer body 6, and the mounting base 2 is fitted when molded. The groove 13 is an inclined groove,
The lower part of the base of the pointer body 6 is buried.

In this second embodiment as well, the lower part of the base of the pointer body 6 is embedded in the mounting base 2 made of dark-colored resin, and as a result, there is no darkening, etc. near the lower part of the base of the pointer body 6, and there are no burrs. The pointer main body 6 has a good color tone, and the pointer main body 6 can be recognized with a clean appearance.

Furthermore, by integrally molding the mounting base 2 and the pointer main body 6 in two colors, it is possible to maintain stable dimensional accuracy of each pointer component, and the weight balance of the entire pointer can be maintained stably.

[Effect of idea]

As mentioned above, the present invention consists of a mounting base that is attached to a pointer shaft, and a pointer body that is disposed on this mounting base and extends in a direction substantially orthogonal to the pointer shaft, with the base of the pointer body in contact with the mounting base. In a pointer composed of a pointer body whose cross-sectional shape becomes thinner toward the left and right edges, the mounting base is formed of a dark-colored resin, the pointer body is formed of a light-colored resin, and the mounting base is formed of a light-colored resin. Since the base and the pointer body are integrally molded in two colors, and the lower part of the base of the pointer body is buried in the upper end of the mounting base, darkening etc. can be prevented near the lower part of the base of the pointer body. , the color tone of the pointer body becomes good, and the overall appearance becomes smooth.

Furthermore, the burrs on the left and right edges of the pointer body are not visible from the outside, which improves the appearance.

Further, by integrally molding the mounting base and the pointer body in two colors, manufacturing is easy and it is possible to maintain stable mounting dimensional accuracy of each pointer component.

As described above, the intended purpose can be fully achieved.
