Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an indicating instrument capable of accurately reading an indicated value.

[Conventional technology]

Conventionally, for example, in an indicating instrument such as a speedometer, in order to reduce the visual error between the pointer and the scale, the one in which the level of the scale and the indicating level of the pointer are the same height is, for example, Japanese Utility Model Publication No. 58-153321. Proposed in the gazette.

This will be specifically described with reference to FIGS. 5 and 6.
Reference numeral 1 is an instrument case, 2 is an instrument body, 3 is a pointer, 4 is an illumination light source, 5 is a display plate, and the display plate 5 is made of a translucent material such as acrylic resin. A dial plate portion 7 above 2 having a numeral representing the speed is three-dimensionally integrally formed through a rising peripheral wall 8 so that the pointer 3 and the scale plate portion 6 are at the same level. .

As a result, even if the reading of the reading is performed in an oblique direction, it can be read in the same state as when viewed from the front of the instrument, and the reading of the reading can be performed accurately.

[Problems to be solved by the invention]

However, since the relative mounting positions of the display plate 5 and the instrument main body 2 are not always constant and the display plate 5 and the pointer have dimensional variations, the distance d between the pointer 3 and the inner peripheral edge of the scale plate portion 6 is small. If set, the tip of the pointer 3 may come into contact with the inner peripheral edge of the scale plate portion 6 and the pointer 3 may become immobile in some cases. Therefore, in the above-described conventional instrument, it is necessary to increase the gap d to some extent.

However, the larger the d dimension becomes, the less effective the visual error becomes. Therefore, the conventional configuration has a limit in accurately reading the indicated value.

In addition, since the rising peripheral wall 8 is upright from the dial plate to the surface of the scale plate, there is a problem that the speed number on the dial plate becomes invisible when viewed from an oblique direction. .

In view of the above-mentioned problems, the present invention has made it possible to more accurately read the instruction value and to prevent the speed number from being shaded even when viewed from an oblique direction. The purpose is to provide an instrument.

[Means for solving problems]

In order to solve the above-mentioned problems, the indicating instrument made by the present invention is constructed by removing a part of the non-translucent coating layer applied on the surface of the translucent base material above the instrument main body installed in the instrument case. A dial having the formed speed figure and a part of the non-translucent coating layer applied on the surface of the transparent base material are removed to form a window hole in the center having a speed scale formed corresponding to the speed figure. A display plate formed by overlapping the formed scale plate with a window is arranged, and the speed is indicated in cooperation with the speed number and the speed scale on the pointer shaft of the instrument body inserted above the dial plate. The pointer to be fixed, the edge portion without a non-translucent coating layer standing up to a predetermined height from the dial, and the scale starting from the upper end of the edge portion were attached around the window hole of the scale plate. Forming an inclined surface and separating the tip of the pointer by a predetermined distance from the inclined surface And introduce the light into the dial from the back surface of the translucent base material and introduce the introduced light into the scale plate from the back surface of the translucent base material. Further, the speed number and the speed scale are derived from the speed scale, and the speed number is illuminated by causing the edge portion to annularly leak light onto the dial.

[Action]

With the above structure, a display plate formed by superimposing a dial plate having speed figures and a scale plate with a window hole having a speed scale formed corresponding to the speed figures is arranged above the instrument body, The pointer fixed to the pointer shaft of the main body cooperates with the speed number and speed scale to indicate the speed. The tip of the pointer is opposed to the inclined surface with a scale that starts from the upper end of the edge formed in the window of the scale plate, with its tip facing a predetermined distance away from the tip of the pointer and its extension. The graduation portion of a certain inclined surface is at the same level, and there is another graduation portion which is continuous with this graduation portion and extends vertically along the sloping surface.

Therefore, the distance between the tip of the pointer and the inclined surface on the extension line can be increased a little, without compromising the effect of reducing the visual recognition error as compared with a scale having only the same level of scale, and Even if there is variation, the tip of the pointer will not hit the scale plate and the pointer will not move.

Also, since the scale is attached to the inclined surface starting from the upper end of the edge part formed in the window of the scale plate, the scale plate becomes an obstacle when the instruction is seen from an oblique direction and the speed number on the dial can be seen. It will never go away.

Since the display plate is formed by superimposing a dial plate and a scale plate with a window hole, which are separate members, it is non-translucent to a translucent base material when forming a scale plate and a dial plate having speed scales and speed figures. The coating layer can be easily formed, and the cost can be reduced. In addition, the light introduced from the back side of the dial is also introduced from the back side to the dial through the dial, and it is derived from the speed figure and the speed scale to shine the speed figure and the speed scale, and the dial from the edge part. Since the area around the speed figure is illuminated by making the light leak in an annular shape above, the brightness of the speed figure due to the transmitted light can be softened.

A coating layer 12b _{4 of} non-translucent paint is provided on the upper surface of the scale plate 12b and the inclined surface 12b ₃ by printing, for example, and a part of the coating layer 12b _{4 on} the inclined surface 12b ₃ is selectively removed. is, speed scale 12b ₅ indicative of the division between the position and speed figures 12a ₄ corresponding to the speed numbers 12a ₄ are given. Above slope
12b ₃ is also provided with a coating layer 12b ₆ made of a light-transmitting white paint, for example, at a position where the scale 12b ₅ is located below the coating layer 12b ₄ .

Vertical width of the inclined surface 12b ₃ is greater than the thickness of the tip of the pointer 13, the tip of the pointer 13 is opposite is separated a predetermined distance d in a substantially central portion thereof.

Reference numeral 14 denotes a plurality of illumination light sources provided in the instrument case 10 below the display plate 12, and the illumination light source 14 is turned on by turning on a lighting switch of the vehicle, and the display plate is displayed when the surroundings are dark like at night. Illuminate the back of twelve. Illumination light from the illumination light source 14 is first introduced into the dial 12a made of a transparent base material and guided through the dial 12a. The light guided by the dial 12a shines on the speed numeral 12a ₄ attached to the dial 12a, is reflected by the reflecting surface provided in the hole 12a ₁ , and is introduced into the pointer 13 from the base of the pointer 13 to guide the pointer. Shine 13

Part of the light introduced into the dial 12a is part of the dial 12a and the scale 12
It is introduced into the scale plate 12b through the contact surface with b, and the scale plate 12b
Will be guided through. Light guided by the scale plate 12b is a speed scale 12b ₅ which was subjected to the inclined surface 12b ₃ of the scale plate 12b causes the bright, is light leakage in an annular by painting layer 12b ₄ free edge portion 12b ₂ and the dial 12a The speed number 12a ₄ on the surface is illuminated from the front side of the dial 12a.

Further, 12a ₆ is a light control layer made of a translucent paint provided on the lower surface of the dial 12a, and the light control layer 12a ₆ is close to the illumination light source 14 and a scale 12b _{5 which} is too bright than other parts. It is provided at a position between the light source 14 and the light source 14.

With the above arrangement, the speed scale 12b ₅ attached to the inclined surface 12b ₃ of the tip of the pointer 13 are opposed to the same level of parts and levels of the pointer 13 along the inclined surface 12b ₃ continuous to the portion There is another scale part extending vertically. Therefore,
Even if the distance between the tip of the pointer 13 and the inclined surface 12b ₃ on that extension somewhat larger, without impairment of the effect of reducing the visibility error as compared with the same level scale there is only conventional. Therefore, even if the display plate 12 and the pointer 13 have dimensional variations, the tip of the pointer 13 does not come into contact with the inner peripheral edge of the scale plate 12b and the pointer 13 does not move.

Also, the window hole 12b ₁ of the scale plate 12b, since the inclined surface 12b ₃ extending from the edge portion 12b ₂ on the surface thereof is formed, a dial scale plate 12b becomes an obstacle when viewed instruction from an oblique direction 12a
The speed number 12a ₄ above will not disappear.

Since the display plate 12 is formed by superposing the dial plate 12a of another member and the scale plate 12b with a window hole, it is possible to transmit light when forming the scale plate 12b and the dial plate 12a having the speed scale 12b ₅ and the speed numeral 12a _4. It becomes easy to form the non-translucent coating layers 12b ₆ and 12a ₅ on the transparent substrate,
The cost can be reduced. Further, the light introduced from the back surface of the dial 12a is also introduced into the scale plate 12b through the dial 12a from the back surface thereof, and is derived from the speed number 12a ₄ and the speed scale 12b ₅ to shine the speed numbers and the speed scale. With
Since light is annularly leaked from the edge portion 12b ₂ onto the dial plate 12a to illuminate the periphery of the speed figure 12a ₄ , the brightness of the speed figure due to the transmitted light is softened and a display that does not tire the eyes can be obtained.

〔effect〕

As described above, according to the present invention, the display plate formed by superimposing the dial plate having the speed numbers and the scale plate with the window having the speed scale is arranged, and the pointer cooperates with the speed numbers and the speed scale. The speed can be indicated by using the graduation, and in particular, the three-dimensional speed display can be performed by the inclined surface having the scale, which is excellent in design.

Then, the tip of the pointer and the graduation portion of the inclined surface on the extension line are at the same level, and there is another graduation portion that extends in the up-down direction along the sloping surface and is continuous with this graduation portion. Therefore, compared to the conventional case, the effect of reducing the visual recognition error is not impaired, the distance between the tip of the pointer and the inclined surface on the extension line can be slightly increased, and even if the display plate and the pointer have dimensional variations, The tip of the pointer will not hit the scale plate and the pointer will not move.

Further, since the sloping surface starting from the upper end of the edge portion is formed on the scale plate, the scale plate does not obstruct the view of the speed figure when the instruction is seen from an oblique direction.

Since the display plate is formed by superposing the dial plate and the scale plate with the window hole which are separate members, the non-translucent coating layer can be easily formed on the translucent base material, and the cost can be reduced. In addition, the introduced light is derived from the speed figure and the speed scale to illuminate the speed figure and the speed scale, and the periphery of the speed figure is illuminated by circularly leaking from the edge onto the dial plate, and the speed due to the transmitted light. It will soften the radiance of numbers.
