However, it is a matter of course that a control means for controlling a specific apparatus is provided in the apparatus, so even if the function of the control means is omitted, it is of course implied that the control means is provided in the description.

The present invention relates to a beam projector lift accommodated in a stage, which is vertically and horizontally moved in use and exposed to the outside of the stage.

FIG. 1 schematically illustrates the installation of a beam projector lift according to an embodiment of the present invention. The beam projector 100 is installed below (under, inside) a stage 10, .

At this time, it is a matter of course that the stage 10 includes a housing (or an inner space) capable of accommodating the beam projector 100 therein.

The beam projector 100 includes a guide rail 121 which is partly contained in the stage 10 and the other part is exposed to the outside of the stage 10, Can be exposed.

The beam projector 100 exposed to the outside of the stage 10 by a certain distance can be vertically moved (vertically moved) by the vertical movement unit 110.

Accordingly, safety and stability can be secured as compared with a beam projector lift used in a conventional ceiling, and even if a beam projector is installed on the floor, the space is not occupied.

Hereinafter, a structure for vertically and horizontally moving the beam projector lift according to the present invention will be described with reference to the accompanying drawings.

2 of the accompanying drawings, the vertical moving part 110 includes a base 111, a vertical control motor 112, an X-lift guide moving rod 113, an X-lift guide 114 and an X- can do.

The base 111 may include an X-lift 115 and an X-lift guide moving rod 113, which can vertically move the beam projector 110 by installing the beam projector 100.

The vertical control motor 112 is formed on one side of the base 111 and performs a function of transmitting rotational force to the X-lift guide moving rod 113, which will be described later.

That is, as shown in FIG. 2 of the accompanying drawings, a gear may be formed at one end of the vertical control motor 112, and a gear engaged with the gear of the vertical control motor 112 may be formed at the X- The rotational force generated in the vertical control motor 112 can be transmitted to the X-lift guide moving rod 113.

At both ends of the X-lift guide moving rod 113, threads may be formed on one surface thereof. As shown in FIG. 2 of the accompanying drawings, the threads formed at both ends of the X-lift guide moving rod 113 may be formed so that their ends are symmetrically formed to be opposite to each other.

This is because the X-lift guide 114, which will be described later, is moved by the rotation of the X-lift guide moving rod 113, and both ends of the X- The X-lift guides 114 should be moved in opposite directions.

Such an X-lift guide moving rod can be installed on the base 111 by the support member 116 as shown in FIG. 2 of the accompanying drawings.

As shown in FIG. 2, the X-lift guide 114 may include two X-lift guide rods 113 and may be fitted to the X-lift guide rods 113. The X- 114 may be close to each other and away from each other.

The first X-lift (115a) and the second X-lift (115b) may be connected to the two X-lift guides (114).

That is, the X-lift 115 is moved upward when the X-lift guide 114 is brought close to the X-lift guide 114 by driving the vertical control motor 112, and is moved downward when the X- .

In this case, the beam projector lift according to the present invention is operated by the rotational force of the vertical control motor and the thread formed on the X-lift guide moving rod 113. When foreign substances such as dust are generated on the thread, Is moved slower or faster than the other one, so that the beam projector 100 installed at the uppermost end thereof may be lost in the center. In this case, the beam projector 100 may be damaged or may be injured There is a concern.

Accordingly, in order to solve the above-described problem, another embodiment of the present invention can detect whether the two X-lift guides 114 are operated while maintaining a certain distance from each other. This is illustrated in FIG.

Figure 3 schematically shows the construction of a vertical moving part in a beam projector lift according to another embodiment of the present invention.

3 of the accompanying drawings, the distance measuring means 116a is provided on the support member 116 for supporting the X-lift guide moving rod 113 and the reflecting means 114a is provided in the lower direction of the X- Can be designed to be extended.

At this time, since the reflecting means 114a must be moved along the X-lift guide 114, it is preferable that the reflecting means 114a is formed to be shorter than the supporting member 116. [

The distance measuring means 116a may be means for outputting light or infrared rays and the reflecting means 114a may be a means for reflecting the light outputted from the distance measuring means 116a, Lt; / RTI >

The distance measuring means 116a may include not only means for outputting light, infrared rays, etc., but also means for receiving light, infrared rays, and the like reflected from the reflecting means 114a.

Finally, the distance measuring means 116a can measure the distance from the distance measuring means 116a to the reflecting means 114a by analyzing the received light, which is the time of flight (TOF) of the light By analyzing, it can be seen how close the reflection means 114a is from the distance measurement means 116a.

Thus, it is possible to detect whether the two X-lift guides 114 move with the same distance around the distance measuring means 116a.

Furthermore, if the two X-lift guides 114 do not maintain the same distance around the distance measuring means 116a, an alarm or an additional communication means (not shown in the drawing) is provided in the support member 116 And notify the controller 200, which will be described later.

The horizontal moving part 120 allows the base 111 of the beam projector lift according to the present invention to be horizontally moved so as to be drawn out or received from the stage 10.

Such a horizontal moving part 120 can be explained with reference to FIGS. 4 to 6 of the accompanying drawings, which schematically show the construction of a horizontal moving part in a beam projector lift according to an embodiment of the present invention have.

4 of the accompanying drawings may constitute a plurality of wheels 122 on the lower surface of the base 111 (the opposite surface on which the vertical moving part is constituted).

In this case, the number of the wheels 122 may be four as shown in the accompanying drawings. However, since the scope of the present invention is not limited to the drawings, the number of the wheels 122 may not necessarily be four, Enough is enough.

The wheel 122 may include a wheel shaft 122a and a wheel gear 122b which connects wheels facing each other among a plurality of wheels and the wheel shaft 122a rotates The wheel 122 is rotated.

The wheel gear 122b may be formed on one side of the wheel shaft 122a.

The horizontal control motor 123 is installed in the direction in which the wheels 122 of the base 111 are formed and may be formed with a motor gear 123a which is in contact with the wheel gear 122b .

Accordingly, when the horizontal control motor 123 rotates, the motor gear 123a transmits the rotational force to the wheel gear 122b, the wheel shaft 122a can be rotated by the wheel gear 122b, and the wheel 122 Can be rotated in the direction of rotation of the wheel shaft 122a to move the base 111.

The movement and removal of the base 111 may be enabled by moving along the guide rail 121, which can be referred to FIG. 5 of the accompanying drawings.

According to Fig. 5, the guide rails 121 may be formed of a plurality of stages. In the accompanying drawings, the first guide rail 1211, the second guide rail 1212, and the third guide rail 1213 are divided into three stages. However, the scope of the present invention is not limited to the drawings, and it goes without saying that it may be composed of two stages or more than three stages according to design conditions.

The wheel 122 formed on the lower surface of the base 111 may be mounted on the lower side of the guide rail (1213 in Fig. 5) of the last stage distant from the base 111 And a guide wheel formed on the lower side of the guide rail at the last stage).

That is, since the wheel 122 is at the same height as the guide rail at the last stage, the base 111 can be stably moved.

Referring to FIG. 5 of the accompanying drawings, the guide rail 121 may include a first guide rail 1211, a second guide rail 1212, and a third guide rail 1213, The second guide grooves 1212a and the third guide grooves 1213a may be formed on the upper surfaces of the other guide rails 1212 and 1213 other than the first guide rail 1211 connected thereto.

6, the guide rails 1211, 1212, and 1213 may have guide wheels formed on a lower surface thereof.

A first guide wheel 1211a may be formed on a lower surface of the first guide rail 1211 and a second guide wheel 1212b may be formed on a lower surface of the second guide rail 1212, The third guide wheel 1213b may be formed on the lower surface of the third guide rail 1213. On the other hand, the third guide rail 1213, which is the last stage, may not be provided with the third guide wheels 1213b.

The first guide wheel 1211a can be moved along the second guide groove 1212a and the second guide wheel 1212b can be moved along the third guide groove 1213a.

6, the guide grooves 1212a and 1213a may be closed at one end of the second guide rail 1212 and the third guide rail 1213. This is because each of the guide wheels 1211a, 1212b, and 1213b So that the guide grooves 1212a and 1213a are not separated.

6, the heights of the first guide rails 1211, the second guide rails 1212, and the third guide rails 1213 and the distance between the respective stages are shown, It is sufficient that the height and the spacing are configured only to such an extent that the beam project lift according to the present invention can be smoothly operated, rather than being constructed as a wide space or a high height as shown in FIG. 6 when actually designed.

Although not shown in the drawings, the beam projector lift according to the present invention may further include a power line for electrical control and a communication line for transmitting and receiving signals.

In this case, the power line and / or the communication line is drawn out together with the power line and / or the communication line when the base 111 is taken out or stored, And / or the communication line.

To this end, in the present invention, line storage means (not shown) extends in the same direction as the wheel shaft 122a on one side of the lower surface of the base 111, and line storage means is provided at both ends of the line storage means, (Not shown) for supporting the wire receiving means so as to be spaced apart from the lower surface of the lower surface by a predetermined distance and to rotate the wire receiving means in the circumferential direction thereof.

And a line storage motor (not shown in the drawings) connected to the gear and a gear configured to be engaged with the gear at one end (inside or outside of the support means) of the line storage means.

Accordingly, when the horizontal control motor 123 is controlled so that the guide rail 121 is drawn out, the line storage motor can be operated so that the power line and / or the communication line can be released, When the guide rails 121 are controlled to be accommodated, the line storage motor may be operated together to wind the power line and / or the communication line.

Depending on other design conditions, the line storage motor may not be operated when the guide rail 121 is drawn out. That is, when the guide rail 121 is drawn out, the wire receiving means is rotated so that the power line and / or the communication line is released and drawn out. When the guide rail 121 is received, And / or the communication line can be wound.

According to another design condition, a power line and a communication line are separately wound on the wire receiving means, and a member having a diameter larger than the diameter of the wire receiving means is formed in the center of the wire receiving means, And to be inserted into the means.

In the beam project 100 according to the present invention, when the two X-lift guides 114 are moved by the distance measuring means 116a with the distance measuring means 116a as a center, It is also possible to control each of the X-lift guides 114 to move with the same length around the distance measuring means 116a.

This will be described with reference to FIG. 7 of the accompanying drawings.

7 schematically shows the construction of a vertical moving part in a beam projector lift according to another embodiment of the present invention.

Here, since Fig. 7 describes one example of the vertical moving part in the structure of the beam projector lift of the present invention, it should be noted in advance that the parts overlapping with the contents described above are not duplicated.

7, the X-lift guide rod 113 can be separated into a first X-lift guide rod 113a and a second X-lift guide rod 113b.

As the first X-lift guide rod 113a and the second X-lift guide rod 113b are separated from each other, the vertical control motor 112 is divided into a first vertical control motor 112a and a second vertical control motor 112b And the vertical control motor 112 may be composed of two.

Therefore, when the X-lift guide provided on the first X-lift guide moving rod 113a and the X-lift guide provided on the second X-lift guide moving rod 113b are driven with the distance measuring means 116a being kept at different distances from each other (Rotation force) of the first vertical control motor 112a or the second vertical control motor 112b described above through the control means (not shown) provided on the base 111, The X-lift guide provided on the guide moving rod 113a and the X-lift guide provided on the second X-lift guide moving rod 113b can be controlled to maintain the same distance around the distance measuring means 116a.

When it is detected that the X-lift guide provided on the first X-lift guide moving rod 113a is located farther from the X-lift guide provided on the second X-lift guide moving rod 113b than with respect to the distance measuring means 116a, It is possible to control the driving of the one vertical control motor 112a to be faster or the driving of the second vertical control motor 112b to be slower.

The beam projector lift according to the present invention as described above further includes a separate controller 200 so that the beam projector 100 can be operated remotely.

The control unit 220 functions to control the beam projector 100, the vertical movement unit 110 and the horizontal movement unit 120 and includes a vertical control module, a horizontal control module, a one-touch control module, an emergency stop control module, And an on / off control module.

The vertical control module performs the function of controlling the vertical movement unit 110 described above, and the horizontal control module can perform the function of controlling the horizontal movement unit 120 (horizontal control motor).

That is, it may mean a 'manual' operation in which the beam projector 100 is moved vertically or horizontally according to a single operation.

The one-touch control module can control the vertical and horizontal movement of the beam projector 100 at one time in a single operation, which can mean 'automatic' operation.

The emergency stop control module can perform a function of controlling the emergency stop when the vertical and / or horizontal movement of the beam projector 100 is performed.

That is, when foreign substances such as dust are generated as described above and the X-lift guide moves at a different distance from the center of the X-lift guide moving rod with different distances, the beam projector 100, The parallelism of the support plate (a structure for supporting the beam projector, not shown in the drawings) that supports the beam projector 100 may be reduced and the beam projector 100 may be detached or the apparatus itself may be damaged. 100) must be stopped in an emergency.

At this time, when the controller 200 is installed in a single phase, the X-lift guide moves the center of the X-lift guide moving rod at different distances around the center as described above through the terminal (computer or the like) It may be designed to be displayed on the screen of the terminal so that it can be notified to the user.

That is, although not shown in the drawing, the controller 200 may further include a notification display unit capable of emitting (a) light, (b) alarming, or (c)

When the X-lift guide rod 113 is divided into the first X-lift guide rod 113a and the second X-lift guide rod 113b in the above-described case, And may be designed to control each of the vertical control motors 112a and 112b.

The on / off control module can control the on or off operation of the beam projector 100 by controlling the power on or off of the beam projector 100.

Since the beam projector lift according to the present invention as described above is not buried in the ceiling unlike the conventional beam projector lift, it has the effect of solving the problems such as equipment damage or human injury caused by falling of the beam projector At the same time, it is possible to utilize the internal space widely even if it is not installed on the ceiling.

Further, since the present invention can control the vertical and horizontal movements of the beam projector, respectively, as well as the vertical and horizontal movements can be controlled at a time by the one-touch method, it is easy to control the vertical and horizontal movements of the beam projector There is an advantage that one control is possible, and emergency stop is possible, so emergency stop can be made even if a dangerous situation occurs in moving the beam projector.
