Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the mounting structure of the dial and end plate of indicating instruments, especially those of automobiles, motorcycles, etc. The present invention relates to a mounting structure for an indicating instrument to prevent problems between facing panels.

[Prior Art] In general, for example, an indicating instrument for an automobile has an instrument body 2 such as a speedometer housed in an instrument housing 1 as shown in FIG. The dial 4 is installed and fixed,
The instructions of the pointer 5 provided on the instrument body 2 are displayed on the dial 4.
The instructions on the indicating instrument are read by comparing them with the characters and scales on the display. Further, a lamp 6 is installed on the bottom side of the instrument housing 1,
The display section of the dial plate 4 is illuminated by the irradiated light beam of the lamp 6, so that the display section can be read.

A facing plate 7 is arranged above the dial 4 to hide the internal equipment from the gap between the dial 4 and the instrument housing 1, and the facing plate 7 and the peripheral edge of the dial 4 are overlapped. It is set up. Therefore, the center portion of the dial plate 4 is fixed to the instrument body 2 with screws 3, and the dial plate 7 is placed on the peripheral edge thereof to prevent vibration of the dial plate 4 and hide internal equipment.

However, in order to enhance the anti-vibration effect, it is necessary to attach the dial plate 4 with the overlapping surface of the dial plate 7 and the peripheral edge of the dial plate 4 in close contact with each other.
Therefore, due to vibrations from automobiles, etc., the overlapping portion of the peripheral edge of the dial plate 4 and the facing plate 7 may rub.
Powder may be generated. Further, the interior of the instrument housing 1 housing the instrument body 2 is sealed by the facing plate 7 and the dial plate 4, so that the heat from the lamp 6 tends to be trapped on the lower side of the dial plate 4.

Therefore, in order to solve this problem, for example, in Japanese Utility Model Application Publication No. 187719/1987, a protrusion is provided on the back side of the dial plate provided above the letters, and a protrusion is provided vertically toward the dial plate. A vibration isolating device for a meter has been proposed in which a buffer member is attached to the tip of a protrusion and the buffer member is partially abutted against the surface of a dial to prevent vibration of the dial.

[Problem to be solved by the invention] In the conventional example, vibration of the dial is prevented by abutting a protrusion vertically provided on the back side of the dial against the surface of the dial via a buffer member. However, there is a difference in level between the dial and dial plate that corresponds to the height of the protrusion and the buffer member, and as a result, the dial plate and dial plate do not form a continuous flat surface. Each facing board is visually recognized as an independent component, and cannot be seen as a flat display surface, resulting in difficulty in visibility. Further, since the buffer member is attached to the tip of the protrusion, not only the number of parts increases, but also a complicated assembly operation such as fitting the buffer member to the protrusion is required.

SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide an indicating instrument that can solve the above problems, improve visibility, and prevent vibration of the dial without increasing the number of parts.

[Means for Solving the Problems] The indicating instrument of the present invention stores and fixes the instrument body in the instrument housing, attaches and fixes a dial to the upper part of the instrument body, and arranges a facing plate around the periphery of the dial. In an indicating instrument in which a dial plate is overlapped on the peripheral edge of the dial plate to hide internal equipment located below the dial plate, a button is inserted into the overlapped portion of at least one of the dial plate and the dial plate. A contact recess is formed, and one of the dial plate and end plate is superimposed on the contact recess so that the surfaces of the dial plate and the end plate are continuous and flat, and at least the characters are placed in the abutment recess. An arbitrary number of protrusions are provided on one side of the board and the facing board to partially abut and contact.

[Embodiment] FIGS. 1 to 3 show a first embodiment of the present invention, in which an instrument body 14 such as a speedometer 12 and a tachometer 13 is housed and arranged in an instrument housing 11. A dial 16 is attached and fixed to the top of the instrument body 14 with screws 15, and a pointer 17 is provided on the instrument body 14.
The instructions are read by comparing them with display parts such as letters and scales provided on the dial plate 16. An abutment recess 18 made of a thin plate portion 16b is formed in the peripheral edge 16a on the front side of the dial 16, and above the dial 16, the dial 16 is inserted from the gap between the dial 16 and the instrument housing 11.
A facing plate 19 is provided to hide the internal equipment located below, and a step-shaped abutting recess 20 is formed on the back side of the facing plate 19 in correspondence with the abutting recess 18. By overlapping abutment recesses 18 and 20 of the dial plate 16 and dial plate 19, which are each formed into a thin plate shape, the surfaces of the dial plate 16 and dial plate 19 are configured to form a continuous flat surface. Further, in this embodiment, an arbitrary number of protrusions 21 are formed integrally with the facing plate 19 in the abutting recess 20 of the facing plate 19 to partially abut and contact the abutting recess 18 of the dial plate 16. The abutment recess 2 of the facing plate 19
A gap A is formed between each of the abutment recesses 18 and 20 by directly abutting the protrusion 21 provided at 0 against the abutment recess 18 of the dial 16. Note that 22 in the figure is a lamp for instrument illumination.

Then, the protrusion 21 formed in the abutment recess 20 of the facing plate 19 is inserted into the abutment recess 18 of the dial plate 16.
By directly abutting and contacting the abutting recesses 18 and 20, the overlapping portions of the abutment recesses 18 and 20 do not overlap in a surface contact state, but abut in a point contact state by the protrusion 21, thereby preventing powder and abnormal noise. Since the protrusions 21 are brought into direct contact with the abutting recesses 18 of the dial 16, the vibration of the dial 16 is suppressed.
Unlike the conventional example, there is no need for special parts such as a buffer member, there is no need to increase the number of parts, and there is no need to perform troublesome assembly work such as fitting the buffer member to the protrusion 21. . Furthermore, the heat generated from the lamp 22 disposed on the bottom surface of the instrument housing 11 is transferred to the gap A formed by the protrusion 21 between the abutting recess 18 of the dial plate 16 and the abutting recess 20 of the facing plate 19. Since the heat is emitted above the dial 16 through the air, it is possible to suppress a rise in temperature due to heat within the instrument housing 11 housing the instrument body 14.

Furthermore, in this embodiment, by overlapping the abutment recesses 18 and 20, each of which is formed in a thin plate shape, with the protrusion 21 interposed therebetween, each dial plate 16 and the peripheral portions of these dial plates 16 are hidden. The front side of the dial plate 19 can be made into a continuous flat surface, so that each dial plate 16 and the dial plate 19, which are each made of separate parts, visually appear as a single flat display surface. It is possible to increase the visibility by making it visible as follows.

FIG. 4 shows a second embodiment of the present invention, in which the same parts as in the first embodiment are designated by the same reference numerals. , surface peripheral portion 16a of dial 16
An abutment recess 18 similar to that of the first embodiment is formed in the abutment recess 18, and this abutment recess 18 is overlapped with the back surface of a facing plate 19 formed thinner than the dial 16, and an arbitrary number of protrusions are formed in the abutment recess 18. 21
a is formed, and this protrusion 21a abuts against and contacts the back surface of the facing plate 19.

In this way, in this embodiment, the dial 16
By superimposing a thin facing plate 19 on the abutting recess 18 formed on the surface periphery of the first plate and directly abutting the protrusion 21a provided in the abutting recess 18 against the facing plate 19 in a point contact state, the first The same effects as in the embodiment can be obtained.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, the protrusion may be provided on one or both of the side that contacts the dial plate or the dial plate.

Further, the shape or height of the protrusion may be set as appropriate.

Additionally, since a gap equal to the height of the protrusion is formed between the dial and dial plate, there is a risk that light from the lamp may leak through this gap, but this is due to the gap between the dial plate and dial plate, which overlap. This can be resolved by setting the amount appropriately.

[Effects of the invention] The present invention stores and fixes a meter body in an instrument housing, attaches and fixes a dial plate to the upper part of the meter body, arranges a facing plate around the periphery of the dial plate, and fixes the meter body in an instrument housing. In an indicating instrument in which a facing plate is overlapped on the dial plate to hide internal equipment located below the dial plate, an abutment recess is formed in the overlapping part of at least one of the dial plate and the dial plate; Either one of the dial plate and the end plate is overlapped in the abutment recess so that the surfaces of the dial and the end plate are continuous and flat, and at least one side of the dial plate and the end plate is placed in the abutment recess.
