Summary of the Invention

Problems to be Solved by the Invention

[0004] On the other hand, in the case of Patent Document 1, the position of the suspended object device for entertainment facilities is fixed and the arrangement cannot be freely changed. Also, since the suspended object for entertainment facilities and the rotating drum require a large weight, the supporting member may bend, and the suspended object for entertainment facilities may tilt. Further, when raising the suspended object to the ceiling, if the suspended object and the rotating drum are arranged side by side in the vertical direction (up and down direction), it is necessary to secure a large height of the space in the ceiling area, and there are cases where the ceiling area cannot be sufficiently secured depending on the entertainment facility.

[0005] Therefore, one object of the present invention is to enable the suspended object for entertainment facilities to be freely arranged.

Embodiments for Carrying out the Invention

[0018] Hereinafter, embodiments of the lifting system for suspended objects for entertainment facilities of the present invention will be described with reference to the drawings. However, the lifting system for suspended objects for entertainment facilities of the present invention can be implemented in many different ways and is not to be construed as being limited to the description of the examples shown below. In the drawings referred to in this embodiment, the same parts or parts having the same function are denoted by the same reference numerals, and repeated description thereof will be omitted.

[0019] Also, for the sake of convenience of explanation, terms indicating directions such as upward (upper side), downward (lower side), forward (front side), rearward (rear side), rightward (right side), and leftward (left side) are used. However, the direction in which gravity acts is downward B, and the opposite is upward U. Also, the entrance side (front direction) of the entertainment facility in which the lifting system for suspended objects for entertainment facilities of the present invention is provided is forward F, and the opposite back side (depth direction) is rearward D. Further, when viewed from the front (entrance) side, the right side is rightward R, and the left side is leftward R. Also, in this specification, the left and right directions are collectively referred to as the left-right direction (also referred to as the "first direction"), the up and down directions are collectively referred to as the up-down direction (also referred to as the "second direction"), and the front and rear directions are collectively referred to as the front-rear direction (also referred to as the "third direction"). The left-right direction and the front-rear direction are parallel to the floor surface (also referred to as the "ground") of the entertainment facility.

[0020] Furthermore, in this specification, entertainment facilities include studio facilities and stage facilities that provide entertainment. Studio facilities include film studios, television recording studios, and music studios, which are places for video production, sound recording, photography, etc. Stage facilities include theaters, concert halls, and opera houses, which are places for live performances such as plays, concerts, musicals, operas, and ballets.

[0021] (1. Configuration of a lifting and lowering system for entertainment facilities) The configuration of the suspended object lifting system 1 for entertainment facilities according to one embodiment of the present invention will be described.

[0022] Figure 1 is a schematic top view of an entertainment facility suspension lifting system 1 according to one embodiment of the present invention. As shown in Figure 1, the entertainment facility suspension lifting system 1 includes an entertainment facility suspension lifting device (hereinafter referred to as the "lifting device") 10, a ceiling passageway (also referred to as the "catwalk") 20, an opening 30, and a rail 40. The lifting device 10, the ceiling passageway 20, the opening 30, and the rail 40 are installed in the ceiling area of ​​the entertainment facility 5.

[0023] The lifting device 10 has the function of raising and lowering suspended objects for entertainment facilities by raising and lowering a part of it (the lifting section 100 shown in Figure 2 and later). In one embodiment of the present invention, stage equipment and lighting equipment for illuminating performers installed in the entertainment facility 5 are used as suspended objects for entertainment facilities.

[0024] The ceiling passageways 20 are arranged in a grid pattern. The openings 30 are provided between adjacent ceiling passageways 20. In this example, 20 openings 30 are provided in a 4x5 grid, but the number of openings 30 can be changed as appropriate. The lifting section 100 of the lifting device 10 moves up and down through the openings 30.

[0025] The rail 40 is provided along the front-rear direction. In one embodiment of the present invention, the lifting device 10 can move forward F or backward D of the entertainment facility 5 via the rail 40. One lifting device 10 is provided for one opening 30, but by moving the lifting device 10 via the rail 40, two lifting devices 10 may be provided for one opening 30 to match the size of the opening 30 (for example, lifting device 10-21 is moved so that lifting devices 10-11 and 10-21 are provided for opening 30-1), or three lifting devices 10 may be provided.

[0026] Furthermore, as shown in Figure 1, in one embodiment of the present invention, the lifting devices 10 are arranged side by side in the left-right direction. In this example, lifting devices 10-11, 10-12, 10-13, 10-14, and 10-15 are arranged in a straight line. Each of the lifting devices 10-11, 10-12, 10-13, 10-14, and 10-15 moves up and down through different openings 30. As a result, although each lifting device 10 is provided independently, it can be considered as one large lifting device 10 extending in the left-right direction, and uniform lighting can be achieved.

[0027] (1-1. Configuration of the lifting device) Next, the details of the lifting device 10 will be explained using drawings. Figure 2 is a schematic side view of the lifting device 10 with the batten 120 raised to its highest position. Figure 3 is a schematic front view of the lifting device 10 with the batten 120 raised to its highest position.

[0028] As shown in Figures 2 and 3, the lifting device 10 includes a lifting section 100, a drive section 200, a wire 300, a trolley section 400, a power trolley section 500, an operating section 600, a lifting device support frame 700, and a buffer section 800. The lifting section 100 and the drive section 200 are arranged side by side along the front-rear direction (third direction). When the baton 120 is raised to its highest position, the lower end of the lifting section 100 (in this example, the lower end 120a of the baton 120, which will be described later) and the lower end of the drive section 200 are higher than the upper end 21a of the fall protection section (handrail 21) provided in the ceiling passageway 20. This allows for effective use of the ceiling space, enabling the lifting device 10 to move in the front-rear direction without interfering with the handrail 21 and avoiding the effects of the ceiling height restriction. In addition, the upper part of the lifting device 10 is set at a height that can be reached by hand. This allows for safe maintenance of the lifting device 10.

[0029] In one embodiment of the present invention, one end of the wire 300 is connected to a drive unit 200 (rotating drum 210). The other end of the wire 300 is connected to a lifting unit 100 (baton support frame 111 of the lifting unit body 110). Multiple pulleys 350 are arranged in the wire 300 supply path from the drive unit (rotating drum 210) to the lifting unit 100 (lifting unit body 110) so that a constant tension is applied to the wire 300. The operation of the drive unit 200 (winding or unwinding the wire 300) changes the amount (length) of wire 300 supplied from the drive unit 200 to the lifting unit 100. As a result, the lifting unit 100 can move upward U or downward B (forward and backward direction) by the drive of the drive unit 200. The configuration of each part of the lifting device 10 will be described in detail below.

[0030] (1-1-1. Lifting section 100) Figure 4 is a schematic front view of the lifting section 100. The lifting section 100 includes the lifting section body 110, a batten 120, a batten bracket 130, and an extendable section 140.

[0031] Figure 5 is a schematic top view of the lifting unit body 110. As shown in Figure 5, the lifting unit body 110 has a baton support frame 111 and a frame portion 113. The baton support frame 111 is extended in the left-right direction so that the telescopic portion 140 can be placed on it. The frame portion 113 is provided in a U-shape on both sides of the baton support frame 111 when viewed from above. The lifting unit body 110 (baton support frame 111) is connected to four wires 300 via wire connection portions 115 provided on the upper side of the frame portion 113. The wire connection portions 115 are provided on the left front, left rear, right front, and right rear of the lifting unit body 110. In addition, a power supply mechanism or other parts and components may be provided on the side of the lifting unit body 110.

[0032] Let's return to Figure 4 for explanation. The batten 120 extends in the left-right direction. The batten 120 is made of a metal material (an aluminum frame in this example). The lighting fixture 90 is fixed to one part of the batten 120 via a fastener 91.

[0033] The baton bracket 130 has the function of supporting the baton 120. In one embodiment of the present invention, the baton bracket 130 includes a central baton bracket 130-1 provided at the lower center of the lifting unit body 110, a left baton bracket 130-2 provided at the lower left side of the lifting unit body 110, and a right baton bracket 130-3 provided at the lower right side of the lifting unit body 110. When it is not necessary to describe these baton brackets separately, they will be described as the baton bracket 130. The lower end 130a of the baton bracket 130 is connected to the baton 120. The upper end 130b of the baton bracket 130 is connected to the baton support frame 111.

[0034] The telescopic section 140 has the function of extending and retracting according to the amount (length) of the wire 300 hanging down. Figure 6 is a schematic front view of the lifting section 100, with the frame section 113 of the lifting section body 110 transparent to make the telescopic section 140 easier to see. The lower end 140a of the telescopic section 140 is connected to the baton support frame 111 of the lifting section body 110. The upper end 140b of the telescopic section 140 is slidably connected to a rail 150 that is fixed to the upper part of the ceiling area and extends in the left-right direction.

[0035] The telescopic section 140 is constructed by connecting a plurality of linear frames (also called "subframes 141") having a predetermined length. The uppermost subframe 141 is shorter than the other subframes 141, but may have the same length. In one embodiment of the present invention, a hinge section 143 is provided between one subframe and an adjacent subframe. In this example, three hinge sections 143 are provided in a linear arrangement on the left side and four on the right side. In this embodiment, by passing the power cable and control cable through the telescopic section 140 (subframes 141), the power cable and control cable can be guided to connect to the lighting fixture suspended from the batten 120, and entanglement and disconnection of the power cable and control cable can be prevented.

[0036] Figure 7 is a schematic front view of the lifting device 10 when the lifting section 100 is lowered. In one embodiment of the present invention, as the amount of sag of the wire 300 relative to the lifting section 100 (length of the wire 300) increases, the hinge section 143 gradually opens. When one hinge section 143 opens, the opposite ends of the two subframes 141 corresponding to this hinge section 143 move apart (the distance d141 between the opposite ends of the two subframes 141 increases). As a result, the telescopic section 140 can be extended as the hinge section 143 gradually opens. On the other hand, when the amount of sag of the wire 300 relative to the lifting section 100 decreases and the hinge section 143 gradually closes, the opposite ends of the two subframes 141 move closer together (the distance d141 decreases). As a result, the telescopic section 140 folds and becomes contracted as the hinge section 143 closes. In other words, the hinge portion 143 changes its open / closed state according to the amount of sagging of the wire 300. Therefore, the telescopic portion 140 can extend and retract via the hinge portion 143 according to the amount of sagging of the wire. As described above, the gradual opening and closing of the hinge portion 143 suppresses the shaking of the lifting portion 100, thereby enabling stable lifting and lowering operation of the lifting portion 100. The number of subframes 141 and hinges 143 can be appropriately changed depending on the size (height) of the entertainment facility 5.

[0037] Furthermore, as shown in Figure 6, in one embodiment of the present invention, the connection part C130-2 between the left baton bracket 130-2 and the lifting unit body 110, and the connection part C130-3 between the right baton bracket 130-3 and the lifting unit body 110, are provided outside the connection part C300 between the wire 300 and the lifting unit body 110 (baton support frame 111). This allows the force (load) applied to the baton 120 to be distributed even when lighting equipment is fixed to the baton 120. As a result, deflection of the baton 120 can be suppressed. Details will be described later.

[0038] (1-1-2. Drive unit 200) Figure 8 is a schematic front view of the drive unit 200. As shown in Figure 8, the drive unit 200 includes a rotating drum 210, a rotating drum fixing bracket 220, and a rotating drum support unit 230 (also referred to as the "second support unit").

[0039] The rotating drum 210 has a motor and performs rotational motion. As the rotating drum 210 rotates, the wire 300 is wound up or unwound. In one embodiment of the present invention, the rotating drum 210 simultaneously winds up or unwinds four wires 300. One of the four wires 300 is connected to the left front of the lifting unit body 110 (specifically the baton support frame 111). One of the four wires 300 is connected to the left rear of the lifting unit body 110. One of the four wires 300 is connected to the right front of the lifting unit body 110. One of the four wires 300 is connected to the right rear of the lifting unit body 110. As a result, the lifting unit body 110 is supported at four points, so that the lifting unit body 110 can be raised and lowered stably without tilting. The rotating drum 210 moves from side to side simultaneously with its rotation.

[0040] The rotating drum fixing bracket 220 is provided to fix the rotating drum 210. In this example, the rotating drum fixing bracket 220 is provided on the upper and lower parts of the rotating drum 210. The rotating drum fixing bracket 220 is fixed to the lifting device support frame 700 using fasteners. The rotating drum fixing bracket 220 may also be provided as an integral part of the rotating drum 210.

[0041] The rotating drum support section 230 is provided to support the rotating drum 210 (and the rotating drum fixing bracket 220). The rotating drum support section 230 is provided on both the left and right sides. The lower end 230a (second end) of the rotating drum support section 230 is connected to the lower side of the rotating drum 210 (rotating drum fixing bracket 220). The upper end 230b (first end) of the rotating drum support section 230 is connected to the lifting device support frame 700. In this example, the rotating drum support section 230 has a linear shape.

[0042] (1-1-3. Lifting device support frame 700) The lifting device support frame 700 is a frame for supporting the lifting device 10. The lifting device support frame 700 extends in the left-right direction when viewed from the front. The lifting device support frame 700 is located above the lifting device 10. In this example, the lifting device support frame 700 is made of a light metal material (more specifically, aluminum).

[0043] (1-1-4. Trolley section 400) The trolley section 400 is mounted on the upper part of the lifting device support frame 700. By sliding the trolley section 400 along the rail 40, the lifting device 10 can move forward F or backward D (front-to-back direction) of the entertainment facility 5.

[0044] The trolley section 400 is equipped with wheels. The trolley section 400 is mounted in engagement with the rail 40. In one embodiment of the present invention, the trolley section 400 is mounted on the upper left and right sides of the lifting section 100 and on the upper left and right sides of the drive section 200. The trolley section 400 is mounted on the upper side of the lifting device support frame 700 and is connected to the lifting device support frame 700 using fasteners. The trolley section 400 functions as a component (also called the "first support section") that supports the lifting section 100 and the drive section 200.

[0045] (1-1-5. Power trolley section 500) The power trolley unit 500 is installed in the upper part of the ceiling area (more specifically, the upper part of the lifting device support frame 700). Power is constantly supplied to the lifting device 10 via the power trolley unit 500. As a result, power is secured even when the lifting device 10 moves in the front-rear direction, so the lifting device 10 can use the power to drive the drive unit 200 and perform the lifting and lowering operation of the lifting unit 100.

[0046] (1-1-6.Operation unit 600) The control unit 600 is a component that can be operated by the user. For example, the control unit 600 may include buttons, levers, and a numeric keypad. In this example, the control unit 600 is located on the right side of the lifting unit 100. The user can control the operation of the lifting device 10 by operating the control unit 600. In addition to buttons, levers, and a numeric keypad, a touch panel may also be used for the control unit 600.

[0047] (1-1-7.Buffer section 800) Let's return to Figure 2 for explanation. The buffer sections 800 are provided at both ends of the lifting device support frame 700. Specifically, buffer section 800F is provided at the front end of the lifting device support frame 700. Buffer section 800D is provided at the rear end of the lifting device support frame 700. Figure 9 is a schematic side view showing two lifting devices positioned close together. As shown in Figure 9, buffer sections 800 are present at the most protruding parts in the front-rear direction of each lifting device 10. At this time, the rear buffer section 800-21R of lifting device 10-21 and the front buffer section 800-11F of lifting device 10-11 are in nearest-to-near-near contact. The buffer sections 800 are made of an elastic material (such as resin or a spring) to mitigate the impact when they come into contact. This reduces the impact even if one lifting device 10 collides with another lifting device 10 when moving it in the front-rear direction.

[0048] (1-2. How force (load) is applied to the lifting device 10) Here, we will explain how forces (loads) are applied to the lifting device 10. First, we will explain how forces are applied to the drive unit 200. In Figure 8, the rotating drum 210 of the drive unit 200 has a weight of about 80 to 100 kg, so the connection point C200 between the drive unit 200 (rotating drum fixing bracket 220) and the lifting device support frame 700 contributes as the point of force application FP1-1. At this time, the connection point C400 between the trolley unit 400 and the lifting device support frame 700 contributes as the fulcrum SP1. With the fulcrum SP1 as the center, a point of application AP1-1 with an upward force fAP1-1 is generated on the opposite side of the point of force application FP1-1, which is point-symmetrical to the point of force application FP1-1.

[0049] Here, if the lifting device support frame 700 is made of a light metal material (aluminum frame), if the lifting device support frame 700 is to be supported by the connection part C400 between the trolley part 400 (first support part) and the lifting device support frame 700, a downward force (load) fFP1-1 is applied at the point of force application FP1-1, which may cause the lifting device support frame 700 to bend. However, in one embodiment of the present invention, the connection part C230 (first connection part) between the rotating drum support part 230 and the lifting device support frame 700 is provided outside the connection part C400 when viewed from the front. Since the rotating drum support part 230 is connected to the rotating drum fixing bracket 220 which is located below the rotating drum 210, a downward force (load) fFP1-2 is applied due to the weight of the drive part 200 (rotating drum 210), and the connection part C230 contributes as the point of force application FP1-2. At this time, a point of application AP1-2 is generated at a position opposite (point symmetrical) to the connection point C230, with respect to the connection point C400 (fulcrum SP1). An upward force fAP1-2 is generated at the point of application AP1-2. As a result, the downward force (load) fFP1-1 at the point of application FP1-1 and the upward force fAP1-2 at the point of application AP1-2 cancel each other out. Therefore, the downward force (load) applied to the lifting device support frame 700 is reduced, and the deflection of the lifting device support frame 700 can be suppressed. Note that this explanation applies to the left-side rotating drum support part 230, but the same applies to the right-side rotating drum support part 230. As a result, the lighting equipment 90 can be further stabilized.

[0050] Next, we will explain how force (load) is applied in the lifting section 100. As shown in Figure 6, in the lifting section 100, the connection point C130-2 between the left batten bracket 130-2 and the lifting section body 110, and the connection point C130-3 between the right batten bracket 130-3 and the lifting section body 110 are located outside the connection point C300 between the wire 300 and the lifting section body 110. The following explanation will use the left batten bracket 130-2 as an example. Since the lighting equipment 90 weighs about 100 kg, the part where the lighting equipment 90 is fixed to the batten 120 (in this example, the connection point C130-1 between the central batten bracket 130-1 and the batten support frame 111) contributes as the point of force application FP2-1. At this time, the connection point C300 between the wire 300 and the lifting section body 110 (batten support frame 111) contributes as the fulcrum SP2. With the fulcrum SP2 as the center, a point of application AP2-1 with an upward force fAP2-1 is generated on the opposite side of the point of force application FP2-1.

[0051] Here, if the baton support frame 111 (or baton 120) is supported at the connection part C300, there is a risk that the baton support frame 111 (or baton 120) will bend due to the downward force (self-weight) fFP2-1 at the point of force application FP2-1. However, in one embodiment of the present invention, when viewed from the front, the connection part C130-2 between the left baton bracket 130-2 and the baton support frame 111 is provided outside (to the left) of the connection part C300. Also, the lower end 130a of the left baton bracket 130-2 is connected to the baton 120. The upper end 130b of the left baton bracket 130-2 is connected to the lifting unit body 110. As a result, the force (gravity) of the lighting equipment 90 is applied to the upper end 130b of the left baton bracket 130-2, and the end 130b contributes as a point of force application FP2-2 with a downward force fFP2-2. At this time, with respect to the connecting part C300 which contributes as the fulcrum SP2, a point of application AP2-2 is generated on the opposite side of the point of force application FP2-2, exhibiting an upward force fAP2-2. As a result, the downward force fFP2-1 at the point of force application FP2-1 and the upward force fAP2-2 at the point of application AP2-2 cancel each other out. Therefore, the downward force on the lifting unit body 110 (batten support frame 111) and the batten 120 is reduced, and the deflection of the lifting unit body 110 (batten support frame 111) and the batten 120 can be suppressed. As a result, the lighting equipment 90 can be further stabilized.

[0052] Furthermore, in one embodiment of the present invention, each hinge portion 143 of the telescopic portion 140 is positioned outward from the front side (entrance side of the entertainment facility) when viewed from the front side (entrance side of the entertainment facility) than the connecting portion C300. This further increases the downward force at the point of force application FP2-2. As a result, the upward force at the point of application AP2-2 can be increased, thereby further suppressing the deflection of the lifting portion body 110 (baton support frame 111).

[0053] (1-3. Lifting and lowering motion) Next, the lifting and lowering operation of the lifting device 10 will be described. As shown in Figure 3, when a user performs a lowering operation on the control unit 600 (in this example, pressing the lowering button), the drive unit 200 (rotating drum 210) rotates, the wire 300 is supplied to the lifting unit 100, and the amount of wire hanging down (the length of the wire hanging down) increases. At this time, as shown in Figure 7, the uppermost hinge 143 of the telescopic unit 140 opens, the uppermost subframe 141 and the unconnected end of the second subframe 141 separate, and the telescopic unit 140 extends. By repeating this operation, the lifting unit 100 can be lowered to near the floor surface of the entertainment facility 5, as shown in Figure 10. On the other hand, when an upward operation is performed on the control unit 600, the opposite operation is performed. As a result, the lifting device 10 can be raised. Therefore, by using one embodiment of the present invention, the lifting unit 100 of the lifting device 10 can be easily raised and lowered in the vertical direction.

[0054] Furthermore, in one embodiment of the present invention, the lifting unit 100 and the drive unit 200 are arranged side by side in the front-to-back direction. As a result, when the batten 120 of the lifting device 10 is raised to its highest position, the space in the ceiling area can be used more effectively compared to when the lifting unit 100 and the drive unit 200 are arranged side by side in the vertical direction (up and down direction), and there can be more headroom in the ceiling area (the height restriction in the ceiling area is relaxed). Therefore, when the batten 120 is raised to its highest position, the lower end 120a of the batten 120 can be raised to a position higher than the upper end 21a of the handrail 21 of the ceiling passage 20. As a result, the lifting device 10 can be moved in the front-to-back direction without interfering with the handrail 21, and lighting equipment can be freely positioned.

[0055] Figure 11 is a schematic diagram showing the usage state of an entertainment facility 5 in an entertainment facility lifting system 1. As shown in Figure 11, the entertainment facility 5 is equipped with a lifting device 10 on which lighting equipment 90 is placed, a stage set 60, and performers 70. Therefore, by using one embodiment of the present invention, the lighting equipment 90 can be positioned at a desired position (vertical position (height), front-to-back position), and various performances can be carried out according to the specifications of the entertainment facility 5.

[0062] In one embodiment of the present invention, one end of the wire 300 is shown to be connected to the baton support frame 111 of the lifting unit body 110, but the present invention is not limited thereto. The wire 300 may be connected to other parts of the lifting unit body 110 (for example, the frame part 113). Also, in one embodiment of the present invention, the rotating drum support part 230 is shown to be connected to a rotating drum fixing bracket 220 located on the underside of the rotating drum 210, but it may be connected to the rotating drum 210 itself as long as it is on the underside of the rotating drum 210.
