Description

[Detailed explanation of the idea] The present invention relates to a hand microphone holding device.

A hand microphone such as a vehicle-mounted radio is engaged and held by a hand microphone holding device when not in use.

Therefore, this type of holding device is required to be able to smoothly attach and detach the microphone, and to be able to securely hold the microphone when the microphone is not in use.

This is to withstand vibrations while the car is running, and also to prevent repeated ON/OFF switching due to vibrations when an electric circuit is formed by the microphone and the holding device.

A conventional hand microphone support device is constructed as shown in FIGS. 1 and 2.

That is, a locking disk 2 is attached to the upper part of the back surface of the microphone 1, and a neck portion 3 having a smaller diameter than the disk 2 is formed between the disk 2 and the back surface of the microphone.

On the other hand, the Dashboard panel 4 of an automobile has a U-shaped support having an opening 5 wide enough to allow the disc 2 to pass through on the top surface and an opening 6 wide enough to engage the neck 3 on the front side. A plate 7 is attached.

8 indicates a screw for attaching the support plate.

Note that a tongue-shaped tongue piece 9 is formed at the edge of the six-shaped front opening, and this tongue piece 9 is designed to act as a leaf spring.

In the conventional microphone support device described above, the microphone is supported as shown in FIG.

That is, the user looks into the opening 5 on the upper surface of the support plate 7 with the disc 2, looks into the opening 6 on the front surface with the neck 3, and pulls the microphone 1 downward.

Then, the disc 2 resists the elasticity of the tongue piece 9 and moves downward while pushing it towards the dash board panel 4, and is sandwiched between the tongue piece 9 and the inner surface of the support plate 7, and the microphone State supported.

Now, if the gap between the tip of the tongue piece 9 and the inner surface of the support plate 7 is a, and the thickness of the disc 2 is b, then how small a is relative to b will allow for smooth attachment and detachment of the microphone and appropriateness to the microphone. I try to obtain a good holding power.

The forces acting on the tongue 9 include the force pushing the tongue toward the dash board panel 4, as well as the frictional force exerted by the disc 2 on the tongue 9.

On the other hand, the tongue piece is a supporting leaf spring and is likely to buckle due to the above-mentioned frictional force, so there are restrictions on the plate thickness t, length 1, etc. of the tongue piece, and it must have sufficient performance as a spring. is difficult.

That is, since the plate thickness t of the tongue piece 9 cannot be made smaller, the amount of deflection of the tongue piece 9 must be made smaller, and therefore the dimension a
, l) had to be highly accurate.

The present invention has been made based on the above-mentioned circumstances, and provides a handheld microphone support device that allows smooth attachment and detachment of a microphone and does not cause buckling of a leaf spring that holds the microphone.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

3A-3B show the support plate of the device of the present invention.

The support plate 10 has a gutter-like shape with wing plates 11 protruding from both sides for attachment to the dash board panel, and its front plate 10
A notch 12 is provided at one end edge of the notch 12, which is formed by a tapered part 12a whose width gradually narrows toward the other end, and a straight part 12C which has an arcuate end 12b connected to the tapered part 12a.

Further, long holes 13 are provided in the side plates 10b on both sides of the front plate 10b, respectively, located near the ends thereof, and curved leaf springs 14 convex toward the inner surface of the front plate 10a are attached to both ends of these long holes. The end of the pin 15 is slidably engaged.

Retaining rings 16 are attached to the ends of these pins 15.

Thus, the curved leaf spring 14 brings the pin 15 into contact with the inner edge of the elongated hole 13.

This state is shown in FIG.

The microphone 1 is supported by engaging the neck portion 3 with the straight portion 12C of the notch 12 and pushing the disc 2 between the inner surface of the front plate 10a of the support plate 10 and the leaf spring 14.

Therefore, in the device of the present invention having the above configuration, the curved leaf spring 1
4 has pins 15 at both ends thereof, and these pins are slidably engaged with elongated holes 13 provided in the side plate 10b of the support plate 10, so that they are deflected by pressure contact with the disc 2. As a result, even if the total length l changes, the change can be absorbed.

Furthermore, as described above, each pin 15 is in contact with the inner edge of the elongated hole 13, so even if a force is applied to the spring in the direction of buckling the spring due to frictional force with the disk, one side Pin 15 of
supports the frictional force, and the other pin 15 slides in the elongated hole 13 in the direction of the frictional force, so that no compressive load that causes buckling acts on the spring.

As mentioned above, since there is no risk of buckling of the spring 14, there is a great degree of freedom in selecting the plate thickness and length l of the spring 14, and the amount of deflection and pressing force of the spring can be set according to the usage condition.

Furthermore, in the device of the present invention, the leaf spring 14 has pins 15 attached to both ends and does not have an open end like the tongue piece 9 shown in FIG. There is no risk of damage to the spring due to catching on other objects.

Note that by making the side panels double and providing long holes in the inner side panels, the pins can be prevented from protruding to the outside.
