Abstract

PURPOSE:To firmly attach a measuring instrument to an attaching plate and to improve the vibro-isolating property of the measuring instrument by setting an elastic supporting member consisting of a collar part and a leg part to the attaching hole of the attaching plate and providing the leg part with a tongue part which clips the measuring instrument and providing the measuring instrument with a slip suppressing part. CONSTITUTION:An annular groove 19 of an elastic supporting member 5 made of rubber is fitted to an attaching hole 3 of an attaching plate 1 to set the member 5. A measuring instrument 7 is pushed into a holding hole 20 of the member 5, and the side wall of a case 13 expands a tongue part 25 of the member and gets over the upper end of an inclined projecting part 17, and then, slip of the measuring instrument 7 is suppressed by a step part 17a. Since the measuring instrument 7 is elastically clipped with a minute gap (S) between the measuring instrument 7 and the member 5 and is held with a gap (t) between the measuring instrument 7 and the wall surface of the holding hole 20 of a collar part 9 of the member 5, the measuring instrument has an excellent buffer function against oscillation from the attaching plate 1. Consequently, the measuring instrument has the damper function against oscillation and is surely attached to the attaching plate with one-touch work.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for instruments mounted on automobiles, motorcycles, etc.

[Prior Art and its Problems] Conventionally, this type of mounting structure is known, for example, the one shown in FIG. 5. That is, a deep-drawn bracket 102 is welded to the lower surface of the mounting plate 100, a bolt 106 is welded to the lower surface of the instrument 104, and the instrument 104 is fixed to the bracket 102 using nuts 108 and elastic members 110 and 112. There is.

However, this conventional technique requires many parts such as a deep-drawn bracket 102, bolts 106, bolts 108, and elastic members 110 and 112, which not only complicates the structure but also makes welding work difficult. There was a problem that the workability was not good because it required . In addition, the instrument 104
In order to firmly attach the instrument to the mounting plate 100, it is necessary to create a rigid structure using the bracket 102 and many other parts as described above, but this will make it easier for vibrations from the mounting plate 100 to be transmitted to the instrument 104. . On the other hand, when a flexible structure is used with emphasis on vibration-proofing properties, problems arise such as detachment and rattling of the instrument 104, and therefore, both firm installation and vibration-proofing properties cannot be satisfactorily satisfied.

Also, Utility Model Publication No. 55-42307, Utility Model Publication No. 55-4
Although instrument mounting structures such as those disclosed in Japanese Unexamined Patent Publication No. 2461 and Japanese Utility Model Application Publication No. 55-117920 are also known, they do not have both a strong structure and vibration-proofing properties.

The present invention aims to solve the above-mentioned problems of the conventional technology, and by devising the structure of the elastic support member for attaching the instrument to the mounting plate, the instrument can be firmly attached to the mounting plate with one touch. The object of the present invention is to provide a mounting structure for a meter that has improved vibration isolation for the meter.

[Means for Solving the Problems] In order to solve the above problems, the instrument mounting structure according to the present invention has the following features: An elastic support member is attached to a mounting hole formed in a mounting plate, and the instrument is connected through this support member. In the instrument mounting structure in which the elastic support member is attached to the mounting hole, the elastic support member has a flange portion which is attached to the mounting hole, and a flange portion which protrudes from one end of the flange portion with a predetermined gap from the side wall of the instrument. A tongue part is formed at the lower part of the leg part, and the tongue part is inclined toward the meter and clamps the meter around almost the entire circumference with elastic force. The special effects include the provision of a regulating section that regulates the movement of the instrument in the direction of separation when it comes into contact with the instrument.

[Function] In the configuration of the present invention, the elastic support member is attached to the attachment hole formed in the attachment plate, and the instrument is attached via this elastic support member. A leg portion is provided that projects from one end of the flange portion held together with a gap from the side wall of the meter, and furthermore, the lower end of the leg portion is a tongue portion inclined toward the meter side.

When installing the instrument, the tongue section with this structure holds the instrument with elastic force with one touch by simply pushing the instrument in, and also firmly holds the instrument in a sandwiched state around almost the entire circumference of the instrument. It also has the effect of preventing the meter from falling off by coming into contact with the regulating part of the meter.

Furthermore, since there is a gap between the legs and the instrument, and the instrument is held between the tongues only, vibrations from the mounting plate, etc., are buffered and are not strongly transmitted to the instrument, which improves vibration isolation. is also excellent.

[Example code] An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a sectional view showing how the instrument is mounted, and Fig. 2 is an exploded perspective view. A meter 7 is attached via a member 5. This instrument 7 is a speed meter or the like used in a two-wheeled vehicle, and is composed of a display section 11 having a flange section 9 on its upper part, and a main body section 15 in which a mechanism section for driving this display section 11 is housed in a case 13. ,
A side wall of the case 13 is formed with an inclined protrusion 17 having four stepped portions 17a at equal intervals in the circumferential direction.

The elastic support member 5 is made of rubber, and includes a flange 21 having an annular groove 19 formed on the outer periphery and a holding hole 20 formed on the inner side, and a gauge 7 extending from one end of the flange 21.
The leg portion 23 is provided to protrude toward the side wall of the case 13. The lower end of this leg portion 23 is a tongue portion 25 that is inclined toward the meter 7 toward the tip and is formed to be thin. Note that the inner diameter of the tip of the tongue portion 25 is the same as that of the case 1 when the instrument 7 is not attached.
It is set slightly smaller than the outer diameter of No. 3.

Further, there is a gap 1.5 mm between the holding hole 20 and the case 13.
However, the dimensions of each member are set so that a minute gap s (about 0.5 mm) is created between the tip of the tongue piece 25 and the stepped portion 17a.

In the above configuration, when installing the meter 7, the elastic support member 5 is first attached to the mounting plate 1 by fitting the annular groove 19 of the elastic support member 5 into the mounting hole 3 of the mounting plate 1.

Next, the meter 7 is pushed into the holding hole 20 of the elastic support member 5 in the direction of the arrow. At this time, the tongue portion 25 at the tip of the elastic support member 5 is expanded by the side wall of the case 13, and pushed into the position where the tongue portion 25 passes over the upper end of the inclined protrusion 17. Thereby, the tongue part 25 clamps the meter 7 by elastic force at a position where there is a minute gap S with respect to the step part 17a.

Therefore, when the instrument 7 is pushed into the holding hole 20 of the mounting plate 1, it is reliably held by the tongue portion 25 of the leg portion 23, resulting in excellent workability.

The elastic support member 5 is made of rubber, and has a gap 1 between the walls of the holding hole 20 of the collar portion 9. Since the instrument 7 does not come into direct contact with the instrument 7, the vibrations generated in the IJ4, etc. are not transmitted to the instrument 7 through these, but are only transmitted by the slightly thin tongue portion 25. Therefore, the elastic support member 5 has an excellent buffering effect against vibrations generated in the mounting plate 1. Moreover, instrument 7
Even if a force is applied in the detachment direction, the tip of the tongue portion 25 comes into contact with the stepped portion 17a to prevent the meter from coming off, so that the meter is firmly held. Moreover, since the tip of the tongue portion 25 has a minute gap S with respect to the step portion 17a, it has a damping effect against vibrations.

Moreover, the structure is simple because only the elastic support member 5 is required as a part for removing the instrument 7, and parts such as bolts and nuts are not required.

In addition, since there is no protrusion such as hol], yasu, or shoto on the outer periphery of the instrument 7 as in the conventional technology, other gl)
There is no problem when picking up items.

In the above embodiment, the restricting portion provided here on the case is realized by the inclined protrusion 17, but the same effect can be obtained by using an annular groove 31 formed on the side wall of the case 13 as shown in the third centroid. play.

Further, as a modification of the elastic support member, as shown in FIG. It may be made easier to open to further facilitate installation.

The device to which this embodiment is applied is not limited to vehicles, but is particularly suitable for locations where vibrations occur, such as machine tools.

[Effects of the Invention] As explained above, according to the present invention, by devising the structure of the elastic support member for attaching the instrument to the mounting plate, the instrument can be attached to the mounting plate with one touch, and furthermore, It also has an excellent effect of damping vibrations to instruments.
