The present invention relates to a stage device having a lighting device installed on the ceiling of the stage where the performance is performed, and more particularly to a lifting stage device for moving a plurality of lighting equipment up and down.

The stage is equipped with a variety of devices, such as lighting fixtures that illuminate the stage, effect mechanisms that produce the necessary effects for the performance, and membrane lifting mechanisms that variably accommodate the stage.

These devices are usually mounted on an elevating stage device as a reason for management, maintenance, and performance, so that they can be moved up and down.

1 is a view showing a state of the conventional lifting stage device will be described with reference to this.

In the conventional stage where the performance is performed, a horizontal wall or grid iron 30 or the like forms a structure in which the hanger 20 is connected to provide a predetermined space in the ceiling 10. The space includes a driving unit 200 which is a driving source of an elevating stage device for elevating devices such as a lamp, a machine control panel 700 for controlling the driving unit 200, a terminal box 410, and the like.

On the other hand, a stage device such as lighting (hereinafter referred to as a lighting device) is fixed to the barton 500 connected through the driving unit 200 and the wire rope 130, it is moved up and down in accordance with the operation of the driving unit 200.

In general, the baton 500 includes a pipe 520 for performing a basic support function, and a fly duct 510 electrically connected to a fixture while fixing a lighting fixture, and the terminal box 410 connected to a power line for supplying power. The cable 420 is drawn from to supply the power necessary for the operation of the luminaire.

The cable 420 is wired to be bent in a zigzag shape so that the length of the bar 500 is moved up and down so as not to damage the appearance, and the bent portion 421 is processed to maintain the bent state. On the other hand, the upper surface of the baton 500 includes a cable basket 530 for storing the cable 420 connected to the ceiling 10 side. Therefore, when the bar 500 moves upward, the cable 420 wired in a zigzag form is folded into the cable basket 530, and when the bar 500 moves downward, the cable 420 moves in the cable basket 530. Will be withdrawn and released.

The cable guider 430 may be further included in the space of the ceiling 10 according to the position of the cable 420.

In addition, the wire rope 130 drawn from the driving unit 200 is balanced to the baton 500 while guiding the wire rope 130 along with the rotation of the drum 100 provided in the driving unit 200. The pulleys 310 and 320 are further included.

Therefore, in order to install the stage devices on the stage, it is necessary to secure a certain space on the ceiling of the stage, and it is troublesome to perform the operation of energizing the console device, the machine control panel 700 and the dimmer 800, and the like. In particular, it is very difficult to install conventional stage devices in a space other than the stage space.

4 is a view illustrating a state in which a wire rope is wound around a conventional winding drum, and FIG. 5 is a perspective view illustrating an exploded view of the winding drum.

The drum 100 receives a power source from a rotating shaft 140 that is interlocked with a motor (not shown) and prevents the coil disk 110 from being rotated and the wire rope 130 wound around the coil disk 110 from being separated. Guide disk 120 is guided to be wound in only one direction.

As shown in FIG. 4, the wire rope 130 is wound while being sequentially stacked under the guidance of the guide disk 120. As described above, this is for the smooth shangdong of the stage device due to the nature of the winding mechanism for elevating the stage device up and down.

The winding disk 110 has a holder 113 for fixing one end of the wire rope 130. In addition, an inlet passage 114 for introducing one end of the wire rope 130 into the holder 113 is formed. Accordingly, one end of the wire rope 130 is inserted into the holder 113 through the inlet passage 114, and is separated again due to the hanging hook 131 having a diameter provided at one end of the wire rope 130. Without fail, the wire rope 130 and the winding disk 110 are fixed to each other.

However, when the outer ear 130 is drawn out from the inlet passage 114 and wound along the circumferential surface of the wound disk 110, the outer peripheral surface of the wound disk 110 is wound at the inlet of the inlet passage 114. The wire rope 130 is bent toward the protrusion is formed.

Such protrusions do not detect the wire rope 130 which is continuously wound in a circular manner, and form protrusions, causing eccentricity during rotation of the drum 100 as well as causing vibration due to the winding device.

In addition, when the winding of the wire rope 130 is made on the protrusion, since the winding speed changes instantaneously and hinders the smooth movement of the stage apparatus, application to the stage apparatus requiring delicateness and softness was somewhat unreasonable.

Subsequently, the driving unit 200 includes a limit 210. The limit 210 is to limit the number of revolutions of the drum 100 to control the shankdong range of the barton 500, and in general, after limiting the bar formed with a thread to a certain length and the rotation of the drum 100 By rotating together and engaging the mover formed with a female thread to engage the bar in the longitudinal direction of the bar, when the bar is rotated, the mover moves in one direction through the engagement of the thread and no further movement is possible. The bar will also stop rotating. As a result, the drum 100 stops rotating and limits the movement of the barton 500.

However, the limit 210 is provided with one or more pairs of bars and movers, and is made of a metal material having a large load to ensure sufficient strength. As a result, the load of the limit 210 becomes large.

A cable 420 is included to be folded or unfolded along.

As described above, the stage device according to the present invention can be completed by connecting the wire rope 130 to the fastener 133, without having to place a separate space on the ceiling 10, unlike the conventional stage device described above Therefore, installation and removal of the stage device are facilitated. To this end, the drive unit 200 and the dimmer 800, which are arranged independently, are mounted on the barton 500 'to be integrated, and the base body forming the barton 500' is deformed to provide sufficient support for an increased load. do.

First, the housing 550 has a hollow 551 in which the driving unit 200 and the dimmer 800 are mounted. At this time, since the hollow 551 is surrounded by an outer wall except for an upper surface, the mounted driving unit 200 and the dimmer 800 are not exposed to the exterior. This is because the stage device exposed to the outside by having a separate space on the ceiling 10 to have a clean appearance.

On the other hand, a pipe 520 is formed below the housing 550 to draw wires, data lines, etc. of the lighting device 600 and to fix and support the plurality of lighting devices 600 integrally. The pipe 520 is connected to the fixing plate 553 and the fastener 554 provided in the housing 550 to allow the luminaire 600 to move together with the movement of the housing 550.

In addition, the housing 550 is provided with a jack connector 511. The jack connector 511 is to allow the housing 550 to function as a conventional fly duct 510 (refer to FIG. 1), and a jack provided at an end of an electric wire and a data line of a lighting device 600 may be detachable. Is fitted.

The driving unit 200 includes a motor 201 (see FIG. 9), a drum 100 rotating in cooperation with the motor 201, and a limit (not shown) for limiting the rotation speed of the drum 100. As such, the load is relatively large. Therefore, the drive unit 200 is mounted at the center of the hollow 551 so that the housing 550 having a predetermined length can be stably lifted without being eccentric. Meanwhile, the drum 100 is coupled to the pivot shaft 140 drawn out through the pivot shaft through hole 552 formed in the housing 550, and is disposed to be exposed to the outer wall of the housing 550.

The exposed drum 100 may be greatly inhibited by the appearance of the drum 100, and the outer plate 555 is provided at the center where the drum 100 is located in the housing 550 to cover the drum 100. Can be.

The support plate 540 is disposed on the upper surface of the housing 550. The support plate 540 includes a pulley 310 ′ that supports the entire load of the stage apparatus together with the drum 100. The pulley 310 ′ is disposed to correspond to the direction of the drum 100 exposed on the outer wall so that the pulley 310 ′ may engage with the wire rope 130 drawn out from the drum 100.

As shown, in the embodiment according to the present invention, the wire rope 130 is drawn out from the drum 100 located at the center of the housing 550 and is turned toward the ceiling 10 via the pulley 310 '. In this case, since the wire rope 130 faces the ceiling 10 while wrapping a portion of the outer circumference of the pulley 310 ′, the wire rope 130 bears a predetermined tension received by the wire rope 130.

In general, since the housing 550 will have a quadrilateral plane having a predetermined width, it is preferable that the pulley 310 'is disposed at each of four corners for uniform load distribution of the stage device. Thus, the drums 100 protrude from the front and rear surfaces of the housing, respectively, and the wire ropes 130 are all paired in pairs, respectively, to be connected to the four pulleys 310 '.

The drawn reference numeral '311' is a pulley fixing tool, which protrudes the pulley 310 'from one side of the support plate 540.

Subsequently, the support plate 540 is provided with a cable basket 530. The cable basket 530 is a cable 420 is seated, thereby preventing the dressing of the cable 420 flows downward when the housing 550 is elevated.

In addition, the cable 420 has a bent portion 421 bent a predetermined position in order to prevent the flow down to form a zigzag shape. Therefore, while the cable 420 is folded or unfolded when the housing 550 is raised and lowered, it is possible to prevent the cable 420 from flowing down due to the dressing.

The cable basket 530 on which the cable 420 is seated may be provided on the support plate 540 as a separate item, but the center of the upper surface of the support plate 540 is bent downward to secure a predetermined space. The cable basket 530 may be formed. This structure can be expected to have a higher strength than the support plate 540 is a flat plate shape, it is possible to increase the buffering efficiency against the tension received by the pulley (310 ').

Meanwhile, a guide plate 531 may be further provided to guide the cable 420 to be smoothly inserted without being separated through the narrow entrance of the cable basket 530 formed on the support plate 540.

The hollow 551 may further include a dimmer 800 as well as a driving unit 200. The center of gravity of the entire housing 550 may be biased toward one side due to the biased arrangement of the dimmer 800. To this end, in the stage apparatus according to the present invention, the machine control panel 700 may be mounted at a predetermined position of the hollow 551. The machine control panel 700 mounted in this way will be arranged in the direction of lowering the bias ratio as much as possible corresponding to the installation position of the dimmer 800.

9 is a block diagram showing a configuration of a limit according to the present invention will be described with reference to this.

In the case of lifting stage equipment, the shanghai dong must be completed only from the ceiling to the stage. That is, it should not be more or less. Therefore, a limit should be placed on the shanghai radius of the housing 550, which is the limit of the driving unit 200. The limit is made of a conventional mechanical bar because the load is large, its application is unreasonable in the lifting stage device according to the present invention.

Therefore, in the stage apparatus according to the present invention, a digital limit is used.

To this end, the limit according to the present invention is a brake 221 for reducing the rotation of the motor 201, and a counting encoder disposed on the coaxial 224 of the motor 201 counting the number of revolutions of the coaxial 224 ( 222 and a controller 223 for operating the brake 221 by receiving rotational speed information of the coaxial 224 counted by the counting encoder 222, thereby limiting the operation of the driving unit 200. Run

The counting encoder 222, the controller 223, and the brake 221 communicate with each other through the communication line 225 to control the accurate movement of the stage device as well as reduce the load of the stage device.

On the other hand, in the case of the controller 223, the operation is possible from the outside, it is possible to adjust the moving distance range of the stage device in accordance with the height change between the ceiling and the stage.

6 is a view showing various embodiments of the winding drum according to the present invention, Figure 7 is a view showing a state in which the wire rope is wound around the winding drum according to the present invention will be described with reference to this.

The winding drum 100 according to the present invention has a disc shape having a predetermined thickness, and includes a rotating shaft hole 111 through which a rotating shaft 140 (see FIG. 5) interlocked with a motor (not shown) and a circumferential surface thereof. A winding disk 110 composed of a retracting path 114 cut and formed toward a center from one point of the circumferential surface so that one end of the wire rope 130 is inserted and fixed; It is disposed on both sides of the winding disk 110 to guide the winding position of the wire rope 130, and provided with a rotating shaft hole 121 corresponding to the rotating shaft hole 111, and the same speed as the winding disk 110 In the winding drum 100 of the guide disk 120 is rotated to the one side of the winding direction side of the wire rope 130 at the inlet of the inlet path 114 smooth bending of the wire rope 130 Has a curved portion 114a curved to be curved; The winding disc 110 has a longest length from the center of the rotating shaft hole 111 to the curved portion 114a while its curvature decreases from the outer end of the curved portion 114a along a circumferential surface at a predetermined ratio. The difference in the longest length from the center of the rotating shaft hole 111 to the other side of the inlet side of the inlet passage 114 facing the curved portion 14a coincides with the diameter of the wire rope 130.

As described above, the winding drum 100 according to the present invention is to wind the wire rope 130 used for lifting the stage device, the wire rope 130 is guided by the guide disk 120 The circumference of the disk-shaped winding disk 110 having a thickness corresponding to the diameter of the wire rope 130 is sequentially assembled. Since the thickness of the winding disk 110 is similar to the diameter of the wire rope 130, the wire rope 130 is limited to its movement to the guide disk 120 is disposed on both sides are wound in a single line.

On the other hand, one end of the wire rope 130 is provided with a latch 131 is enlarged in diameter. The latch 131 may be an article that is independent of the wire rope 130, or may be an integrated body having changed the shape of the wire rope 130.

The locking hole 131 is for fixing the winding disk 110 and the wire rope 130 to each other, and a holder 113 corresponding to the locking hole 131 is formed in the winding disk 110. In addition, the holder 113 communicates with the inlet passage 114 cut and formed from the circumferential surface of the winding disk 110.

That is, the holder 113 formed at the center thereof communicates with the outside through the inlet passage 114 formed at one point on the circumferential surface of the locking shaft 110. The inlet passage 114 is formed to be slightly larger than the diameter of the wire rope 130, and when the wire rope 130 is inserted to fill the space of the inlet passage 114. Meanwhile, one end of the wire rope 130 is disposed in the holder 113 through the inlet passage 114. Of course, since one end of the wire rope 130 is inserted into the holder 113 is provided with the catch 131, the wire rope 130 is inserted into the holder 113 to the outside through the inlet passage 114 The wire rope 130 and the winding disk 110 are fixed to each other by this.

On the other hand, since the wire rope 130 drawn out from the inlet passage 114 is wound along the circumferential surface of the winding disk 110, when the wire rope 130 is bent from the inlet to the circumferential surface of the inlet passage 114, The curved portion 114a is curved to smooth the bending.

Subsequently, the winding disc 110 forms a disc shape, the periphery of which is reduced from the outer end of the curved portion 114a by a predetermined ratio. Accordingly, the circumferential surface of the wound disk 110 is exaggerated so that its circumference changes in the shape of a chick.

As the curvature of the circumferential surface of the winding disk 110 changes, the faces facing the inlet side of the inlet passage 114 show a difference in radius from the center of the rotating shaft hole 111 of the winding disk 110.

That is, as shown in FIG. 6, even if the curved portion 114a and the surface facing the curved portion 114a are connected to two spaced apart points showing the height difference L, the center of the inlet passage 114 is a complete circle. This doesn't work. At this time, the height difference (L) is matched with the diameter of the wire rope 130.

As a general standard, the wire rope 130 has a diameter of 4mm, 6mm, 8mm, etc. is widely used, and the winding disk 110 has a diameter of 80mm, 240mm, etc. is widely used.

In the field, the wound disk 110 is used 20 to 30 times larger than the diameter of the wire rope 130, in the embodiment of the present invention, the diameter of the wound disk 110 is 80mm, the diameter of the wire rope 130 It was 4 mm.

Therefore, the height difference L will be 4mm. However, this is only an embodiment according to the present invention, and may be modified in various ways without departing from the scope of the following claims.

As an embodiment of the winding disk 110 according to the present invention, all three are presented in FIG.

First, the embodiment shown in the drawing (a) is a fan shape having a diameter of 80 mm from one of the curved portions 114a to a point between 260 and 280 degrees, and the remaining portion is a fan shape having a diameter larger than 80 mm. Is replaced by. In other words, as the diameter increases, the curvature decreases and a height difference L is generated. The height difference L is artificially adjusted to be 4 mm.

In the embodiment according to the present invention, the sector radius of the remaining part is 93mm, and the center of the sector having a radius of 80mm is the center of the sector having a radius of 93mm in order to maintain 4mm, which is the height difference L. Did not match.

(b) In the drawing, (a) the central angle of the fan shape having a diameter of 80 mm shown in the drawing is smaller than 260 degrees, and the remaining part is replaced with a fan shape having a smaller curvature by making the diameter larger than 80 mm.

(c) In the drawing, the central angle of a fan with a diameter of 80 mm is set to 90 degrees or less, and the remaining part is replaced with a fan having a different curvature with one or more different diameters.

As the various embodiments described above are presented, the method of matching the height difference L to the diameter of the wire rope 130 may be very diverse. That is, the curvature may be reduced from the end of the curved portion 114a little by little, and the same curvature may be maintained up to a predetermined angle, but the curvature may be slightly reduced from the predetermined angle or more, or replaced with a fan shape having a curvature smaller than the existing curvature.

However, the most preferred embodiment seen through the experiments of the present inventors maintains a fan having a diameter of 80mm at a certain curvature from the curved portion 114a to a point between 260 ~ 280 degrees and then the fan shape smaller than the curvature for the remaining portion Is replaced by. This was confirmed through the ease of fabrication of the winding disk 110 and the stability and satisfaction for the actual operation result.

Therefore, by applying the above-described optimal embodiment it is possible to minimize the vibration caused by the eccentricity generated during the rotation, as shown in Figure 7 as the wire rope 130 is wound in a circular shape without the formation of protrusions as the lifting of the stage device It can proceed smoothly and delicately.

Unexplained withdrawal numbers "111a" and "121a" are the engaging groove, the engagement of the unexplained withdrawal number "141" by the rotation of the rotating shaft 140 to the winding disk 110 and the guide disk 120 Make sure it is delivered correctly.

In addition, as shown in Figure 5, the winding drum 100 may be operated in engagement with one or more of the same rotating shaft 140. That is, a plurality of wire ropes are wound around each winding disk 110 so that a plurality of stage devices can be lifted by one driving, or by connecting a plurality of wire ropes to a relatively large stage device so that they can be stably lifted. It is.

8 is a view showing another embodiment of a winding drum according to the present invention, which will be described with reference to the drawing.

In order to reduce the load of the stage apparatus according to the present invention, a plurality of cutting holes 115 and 122 are formed in the winding disk 110 and the guide disk 120 constituting the drum 100. At this time, the cutting holes 115 and 122 are preferably formed as symmetrically as possible in order to minimize the eccentricity rate during the rotation of the drum (100). That is, it is formed regularly along the winding disk 110 and the guide disk 120 so as not to affect other than the weight reduction of the drum 100.

According to the present invention as described above, it is easy to install the stage device even in a non-stage space, it can also be quickly removed, while at the same time minimized the vibration generated during Shanghai can be stable operation.
