2. Description of the Related Art For example, in a stand-type microphone attached to a multimedia personal computer, a movable stem is erected on a base placed on a desk, and a microphone is attached to a tip of the movable stem. . In order to make the microphone unit and the movable stem tiltable with respect to the base, for example, a tilt structure shown in FIG. 5 is used. In the figure, a pair of support pieces 101 are erected on a base 100 so as to face each other, and a circular bearing 102 is formed on each of the support pieces 101. The movable stem 200 to which the microphone 201 is attached has shaft portions 202 protruding from both side surfaces at the lower end thereof, and these shaft portions 202 are fitted and supported by the bearing 102. With this configuration, the shaft portion 202 is rotatable around the axis with respect to the bearing 102, and the movable stem 200 is capable of tilting in the direction around this axis.

[0003]

However, in this conventional tilt mechanism, the movable stem 200 cannot perform a tilt operation only in the direction around the axis of the shaft portion 202 and the bearing 102, as shown by the arrow in FIG. . For this reason, the range of the position of the microphone unit 201 is also limited by the tilt operation, and as a result, the place where the stand-type microphone is placed and the position of the operator who handles the microphone are restricted by the tilt direction of the movable stem. May affect the operability of personal computers and microphones. Also,
When the microphone unit 201 is tilted in another direction, the mounting direction of the base 100 needs to be changed.
It is not easy to change the direction by a microphone cord (not shown) connected to the microphone, and the microphone cord may be twisted, resulting in an undesired use form.

An object of the present invention is to provide a multi-directional tilt mechanism capable of tilting in any direction.

According to the present invention, a base mounted on a desk or the like has a hemispherical seat having an X-direction slit extending in one direction, and is supported by the base to perform a tilt operation. A possible movable stem has a Y-direction slit extending in a direction orthogonal to the X-direction slit, and a hemispherical portion in contact with the hemispherical seat is formed, and penetrates the X-direction slit and the Y-direction slit. And a joint for connecting the hemispherical seat and the hemispherical portion is provided. The movable stem is moved in the X direction and the Y direction by the joint being moved in the X direction slit and the Y direction slit.
The tilt operation can be performed in any direction, and as a result, the tilt operation can be performed in any direction.

Here, the hemispherical seat has a configuration in which a top surface of the base is recessed, and the hemispherical portion has a configuration in which a base end of the movable stem protrudes. The surface portion is formed to have the same diameter. Also, joints penetrate through the X-direction slit and the Y-direction slit, and are movable in the slit extending direction in these slits, and are provided at both ends of the shaft, respectively. It is composed of a head that prevents falling off. Further, it is preferable that a microphone is attached to the tip of the movable stem to be configured as a stand-type microphone.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment in which the tilt mechanism of the present invention is applied to a stand type microphone.
FIG. 2 is a partially exploded perspective view thereof, and FIG. 3 is a longitudinal sectional view thereof. The stand-type microphone includes a base 1 placed on a desk, and a movable stem 2 supported on the base 1 in an upright state and having a microphone 3 integrally attached to a tip end thereof.
It is composed of The base 1 has a hollow structure in which the outer shape is close to a truncated cone and has no bottom plate, and the top surface thereof is formed as a hemispherical seat 11 by being recessed downward in a hemispherical shape. Have been. A boss 21 having a conical shape is integrally formed at the base end of the movable stem 2, and a hemispherical portion 22 is connected to the boss 21 by screws 23. The end surface of the hemispherical portion 22 is formed so as to protrude into a hemispherical shape having the same radial dimension as the hemispherical seat 11 of the base 1, and the inside thereof has a hollow structure.

The hemispherical seat 11 of the base 1 has
A slit 12 extending radially in one direction of the plane, here the X direction, is formed.
The hollow interior of the hemispherical seat 11 is communicated with the outside through the through hole. Further, a Y-direction slit 24 is formed on the distal end surface of the hemispherical portion 22 of the movable stem 2 and extends in the radial direction in the Y-direction orthogonal to the X-direction slit 12. The hollow interior of the surface portion 22 and the outside are communicated.

The hemispherical portion 22 of the movable stem 2
Are supported by a hemispherical seat 11 of the base 1 and are connected to each other by a joint 4 penetrating through the X-direction slit 12 and the Y-direction slit 24. The joint 4 has a shaft portion 41 having a smaller diameter than the width of each of the slits 12 and 24, and a head 42 provided at both ends of the shaft portion 41 and having a larger diameter than the width of each of the slits 12 and 24. , 43, the shaft portion 41 is inserted through the slits 12, 24, and the front heads 42, 43 are provided inside the hemispherical seat 11 and inside the hemispherical portion 22, respectively. Is located. In order to realize this structure, in this embodiment, one head 43 of the joint 4 is configured to be screwed to the shaft 41, and the shaft 41 is connected to the base 1 from below by a hemispherical surface. X of seat 11
The connection can be achieved by inserting the one head 43 into the shaft 41 from the inside of the hemispherical portion 22 after inserting the directional slit 12 or the Y-direction slit 24 of the hemispherical portion 22.

In the stand-type microphone thus constructed, when the movable stem 2 is tilted along the X direction with the base 1 placed on a desk, the joint 4
Is moved integrally with the movable stem 2 in the X-direction slit 12, so that the movable stem 2 can be tilted in the X-direction. Further, when the movable stem 2 is tilted along the Y direction, the joint 4 is relatively moved in the Y-direction slit 24 while being fixed to the base, so that the tilt of the movable stem 2 in the Y direction is increased. Operation becomes possible. further,
When the movable stem 2 is tilted in a direction intersecting the X direction and the Y direction, respectively, the joint 4 moves the base 1 and the movable stem 2 in the X direction slit 12 and the Y direction slit 24.

Therefore, as shown in FIG. 4, the movable stem 2 can be tilted in any direction within the range of the length in which the slits 12 and 24 in the X and Y directions are formed. . This allows the microphone unit 3 attached to the tip of the movable stem 2 to be directed in an arbitrary direction regardless of the position where the base 1 is placed, and a stand-type microphone that has been conventionally regarded as a problem. The location of the device and the position of the operator handling the device are restricted by the tilt direction of the movable stem, so that the influence on the operability of the personal computer and the microphone can be eliminated. In addition, since it is not necessary to change the direction of the base when tilting the microphone unit, the microphone cord is not twisted.

Further, in this configuration, as components for constituting the tilt mechanism, a hemispherical seat 11 on the base side, a hemispherical portion 22 on the movable stem side, and a joint 4 for connecting the two.
Are required only, and the slits 12, 2 formed in the hemispherical seat 11 and the hemispherical portion 22, respectively.
Since only the assembly work of connecting the joints 4 with the joints 4 is sufficient, the number of constituent parts is small, and there is almost no need to adjust the parts.
