Description

Ceiling microphone lifting device {A microphone up and down apparatus}

The present invention relates to a ceiling microphone lifting device, and more particularly, by allowing the microphone to descend from the ceiling, the microphone string is not placed on the floor of the room so that it does not get dirty and hangs, and the microphone stand makes it possible for the performers of church choirs or symphony orchestras. The ceiling microphone lifting device is easy to use because it is not obscured.

In general, the microphone is connected to the amplifier through the microphone string, and most of these microphones are usually used by attaching them to a stage stand. If the stage is large, the mic string should be that long because the amplifier is far away, and the string is placed on the stage.

However, because the microphone string is placed on the stage disorderly, the performers or choirs can walk on the microphone string, and if they are inadvertently caught, they can trip over the string. In addition, in the church choir, the microphones are placed on both sides of the stage, and because of the stand, the choir members are not visible because of the stand, and when the choir ends, the microphone has to be removed to listen to the pastor's sermon.

The present invention was developed in view of the conventional problems, and the object of the present invention is that the microphone string is automatically lowered and raised from the ceiling, and there is no inconvenience in installing the microphone, and the microphone string is not placed on the floor of the room, which is not dirty. And there is no fear of tripping over the line and there is no need to provide a separate stand for the microphone to install a ceiling lifting device.

In order to achieve the above object, the present invention provides a microphone lifting device that lowers or raises a microphone provided in a ceiling toward an interior, and a winding shaft wound around an outer circumferential surface of the microphone is provided to be rotatable inside the main body. On one side, a motor and a reduction gear for forward and reverse rotation of the winding shaft are provided on the same axis as the winding shaft, and the other side of the main body is provided with a bearing for supporting the rotating pipe at the end of the winding shaft, and a microphone cord wound around the winding shaft inside the winding shaft. A passage is formed through the rotating pipe and the bearing to be drawn out of the main body and connected to the amplifier.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of the inventive microphone lifting device and Figure 2 is a side cross-sectional view of the inventive microphone lifting device. The present invention is provided with a rectangular main body 1, the upper part of the main body is open, the open upper part is provided to be opened and closed by the cover (3). And the inside of the main body 1 is provided with a winding shaft 4 to which the microphone string 11 is wound. The winding shaft 4 has one end thereof connected to the reducer 7 provided on the outer wall of the main body 1 via the rotary shaft 8, and the reducer 7 is provided to be driven by the motor 6.

And the other end of the winding shaft (4) is connected to the outer wall of the main body through the rotary pipe (9) and the rotary pipe (9) is fitted to the bearing (10) fixed to the outer wall to reduce the rotational friction of the rotary pipe (9) Supported. Also, the winding shaft 4 has a passage 5 formed therein, and the passage 5 is provided to communicate with the rotary pipe 9. The microphone string 11 is inserted into the passage 5 of the winding shaft 4 through the cylindrical bearing 10 and the rotary pipe 9, and the microphone string penetrated into the winding shaft is drawn out to the outer circumferential surface of the winding shaft. It is provided to.

In addition, the lower end of one side of the main body 1 is formed with an entrance (2) through which the microphone string 11 enters and exits, and the microphone string of the side connected to the amplifier is connected to the bearing 10 along the passage 5 of the winding shaft 4. After being withdrawn, it enters into the main body 1 again and is drawn out of the main body 1 along the entrance 2 and connected to the amplifier. The motor 6 and the bearing 10 are covered by the motor cap 18 and the bearing cap 19 so as not to be exposed to the outside.

In addition, the lifting stop switch 15 and the down stop switch 14 for adjusting the lifting amount of the microphone string 11 are provided at the bottom of the entrance 2 inside the main body 1, and the microphone string 11 is provided with these switches. Lifting projections 13 and the lowering projections 12 for controlling the are provided respectively. Reference numeral 16 denotes a control unit for controlling the motor 6 and the switches 14 and 15 of the main body, 17 denotes a microphone, 11a denotes a roller for guiding the microphone string 11, and 20 denotes a switch wire.

The present invention configured as described above is provided such that the main body 1 is embedded in the ceiling and the microphone 17 is lowered to the stage from the main body. This will be described in more detail as follows. The control unit 16 is provided with a button for automatically lowering the microphone or manually adjusting the amount. When the operation signal is applied to the main body, power is supplied to the motor 6 so that the motor Forward or reverse rotation. When the motor is rotated forward, the microphone string 11 is lowered, and as the rotational force of the motor is decelerated in the reducer 7, the winding shaft 4 is rotated through the rotation shaft 8.

The winding shaft 4 is smoothly rotated by being supported by the bearing 10 through the rotation pipe 9. In the process of rotation, the microphone string 11 wound around the winding shaft 4 is lowered toward the interior through the doorway 2 while being released along each roller 11a provided at the bottom of the main body. Since the end of the microphone string 11 is provided with a microphone 17 connected to the amplifier, the microphone is lowered to the choir or symphony orchestra of the stage. The amount of falling of the microphone is automatically or manually controlled by the controller 16. When the lowering protrusion 12 touches the lowering stop switch 15 as shown in FIG. 4, the power applied to the motor 6 is cut off. The microphone stops descending.

In addition, after using the microphone, the control unit 16 is operated to raise the microphone, and the motor and the winding shaft 4 inside the main body are operated in the reverse order when the microphone descends, so that the microphone string 11 of the winding shaft 4 It is wound around the outer circumference.

As described above, according to the present invention, since the winding shaft in which the microphone string is wound is installed on the ceiling while being stored inside the main body, the microphone string is automatically lowered from the ceiling and supplied to the choir or symphony orchestra in the room. Therefore, the strings are not messed up on the floor of the room, so the stage can be cleaned and the stray strings are prevented from falling over. And it does not need a separate stand to stand the microphone has the effect of making the microphone easier to use.
