Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting device for mounting an audio device such as a microphone to, for example, a VTR camera with one touch.

[Background technology and problems]

Conventionally, when attaching a microphone to a VTR camera or the like, one method of attaching the microphone is to use an accessory shoe as shown in FIG. That is, the main body of the microphone 1 is provided with a mounting shaft 3 having a plate-shaped shoe holder portion 2 at its lower end, and a fixing knob 6 screwed onto the shaft 3 with mutual screws 4 and 5 is provided. , insert the show holder part 2 into the accessory show 8 fixed to the VTR camera 7, and then turn the fixing knob 6 to press the lower protrusions 9, 9 against the upper surface of the accessory show 8. This is the method.

However, according to this method, microphone 1
Although it is possible to securely attach the microphone, since it is necessary to turn the fixing knob 6 to fix it, the size (especially the width) of the microphone body is limited to some extent in terms of operability, and it is difficult to make the microphone large. Then, it is necessary to increase the size of knob 6 accordingly. In addition, the height of the mounting shaft 3 must be increased accordingly.
In other words, it has been difficult to miniaturize the device. Furthermore, there was also the problem that rotating the knob 6 was cumbersome when attaching and detaching.

[Purpose of invention]

The present invention was developed in view of the existing circumstances, and its purpose is to provide a mounting device for audio equipment that can be made smaller and that can be mounted and removed with one-touch operation. Our goal is to provide the following.

[Summary of the idea]

The features of the present invention include an accessory shoe fixed to an object to be attached such as a VTR camera, a housing fixed to the main body of an audio device such as a microphone to be attached to the object, and a shaft portion inserted into the housing. A rotary body having a plate-shaped shoe holder portion inserted into an accessory shoe at its lower end and an arm portion extending left and right at its upper end; a fan-shaped groove having an inclined bottom surface on which the lower surface of the arm slides; one end is loosely attached to the lower surface of the housing, and the leg portion of the lower end abuts the upper surface of the accessory shoe. It consists of a fixing bracket and an elastic body installed between the legs of the fixing bracket and the lower surface of the housing.When installing audio equipment, after inserting the shoe holder part of the rotary body into the accessory shoe, the acoustic All you have to do is rotate the main body of the device by a predetermined angle, and when removing it, all you have to do is rotate the main body of the audio device by a predetermined angle, return it, and then pull out the shoe holder from the accessory shoe. be.

〔Example〕

Hereinafter, the present invention will be explained in more detail with reference to illustrated embodiments.

FIG. 2 shows the entirety of the present invention. In this example, a microphone is shown as the audio device 11, and the mounting device 12 is mounted on the bottom side of the microphone 11. On the other hand, this microphone 1
1 is attached to, for example, a VTR camera 13 (not shown), and the accessory shoe 14 is mounted on the top surface of the VTR camera so that its insertion direction is perpendicular to the axis of the camera lens. It is installed as follows.

The structure of the mounting device 12 is as shown in FIG. 3. A housing 15 is fixed to the microphone body side, and a shaft portion 16 is inserted through the housing 15 and screwed with mutual screw portions 17 and 18. A rotating body 19 is set. Furthermore, this rotating body 19
may be simply inserted without the threaded portions 17 and 18.
As shown in FIG. 4, this rotating body 19 has a plate-shaped shoe holder portion 20 at its lower end that is inserted into the accessory shoe 14, and its upper end has a shoe holder portion 20 extending from side to side that is fixed with, for example, screws 21. Arm parts 22, 22 are provided. This arm portion 22,
Preferably, protrusions 23, 23 are provided on the lower surface side of 22.

Arm portion 2 of the rotating body 19 formed in this way
2 and 22 are housing 15 as shown in FIG.
A fan-shaped groove 2 formed as a hollow part on the upper surface side of the
It is housed in 4,24. The size of the arc of these grooves 24, 24 is determined by the size of the accommodated arm portions 22, 22.
is large enough to rotate within an angle range of approximately 90°,
Further, the bottom surfaces of the grooves 24, 24 near the peripheries are sloped bottom surfaces 25, 25 that are gently sloped from one side to the other, as shown in FIG. This bottom surface 25,2
Reference numeral 5 denotes a portion on which the protrusions 23, 23 of the arm portions 22, 22 slide, and due to the relationship between the housing 15 and the rotating body 19, when the two rotate approximately 90 degrees relative to each other, the shoe holder portion of the rotating body 19 slides. 20 is raised and lowered by the slope height. This slope height is, for example,
It is best to set it to about 0.5mm. Also, at this time, arm portions 2 are located near the left and right ends of the inclined bottom surfaces 25, 25.
It is preferable that protruding ridges 26, . Also, when the arm parts 22, 22 are rotated, the grooves 24, 24
Both edge portions 24a, 24a on the center line side function as stoppers and restrict rotation to approximately 90 degrees.

On the lower side of the housing 15 formed as described above, fixing fittings 29, 29 whose upper ends are freely fitted up and down into engagement holes 28, 28 of a part of the housing 15, for example, the protruding parts 27, 27, are attached. The lower ends of the fixing fittings 29, 29 are, for example, leg portions 30, 30 approximately in the shape of an inverted L, so as to face and come into contact with the accessory shoe 14. Furthermore, the legs 30, 30 and the housing 15
A ring-shaped elastic body 31, for example, a spring material, is attached between the lower surfaces of the .

The microphone 11 can be attached to and detached from the VTR camera 13 using the attachment device 12 of the present invention constructed as described above in the following manner.

First, at the time of mounting, as shown in the above-mentioned FIG.
2 is positioned at the lower part of the inclined bottom surfaces 25, 25 of the fan-shaped grooves 24, 24 of the housing 15, and in this state, as shown in FIG. Insert it into the accessory show 14. As a result, the shoe holder section 20 is temporarily fixed, but in this state, the direction of the microphone 11 is orthogonal to the axial direction of the lens of the VTR camera, so the microphone side or the VTR camera side must be moved relative to each other. Rotate it. Then microphone 1
1 coincides with the direction of the lens of the VTR camera 13, and especially in the case of a directional microphone, a good recording condition is immediately achieved, and at the same time the rotating body 19
Due to the rotation of the arm portions 22, 22, the inclined bottom surface 2
5, 25 to reach the high part as shown in FIG. Therefore, at this time, the rotating body 19 tends to be lifted by the inclination height relative to the housing 15, and conversely, when viewed from the housing side, the housing 15 tends to be pushed down. For this reason, the shoe holder portion 2 of the rotating body 19
The upper surface of the accessory shoe 14 is firmly pressed against the inner surface of the accessory shoe 14. Also, the fixing fittings 29, 2 are relatively
Since the distance between the legs 30, 30 of the fixing fittings 29, 29 and the lower surface of the housing 15 becomes slightly shorter, the spring pressing force of the spring members 31, 31 increases.
0 and 30 firmly press the top surface of the accessory shoe 14. In other words, by one-touch operation of inserting and rotating, the microphone 11 can be firmly attached to the VTR.
It is attached to the camera 13.

When removing the microphone 11 next time, the microphone 11 is returned to its original position and rotated, and then the shoe holder section 20 of the rotating body 19 is pulled out from the accessory shoe 14 of the VTR camera 13.

[Effect of idea]

As is clear from the above explanation, according to the present invention, there is no need for a conventional fixing knob, so it is possible to downsize the device, and the mounting strength is high when it is installed.Moreover, it has the advantage of being able to be attached and detached with a single touch operation. A mounting device for audio equipment can be provided.
