Description

  Embodiments of the present invention relate to an illumination baton device that suspends a lighting fixture from a ceiling of a television studio or a theater, and an illumination system in which a plurality of the illumination baton devices are arranged side by side.

  Conventionally, when a lighting fixture is suspended from a ceiling of a television studio or a theater, an illumination baton device that can collectively support a plurality of lighting fixtures so as to be movable up and down is used. The lighting baton device generally has a baton for hanging a plurality of lighting fixtures, a hoisting machine fixed to a grid installed on the ceiling, and a plurality of hanging wires connecting the baton to the hoisting machine.

  For example, in order to irradiate the desired illumination light from above the studio set, it is desirable to prepare a plurality of lighting fixtures according to the layout of the studio set and individually adjust the height position of each lighting fixture. . For this reason, usually, a plurality of lighting baton devices are arranged side by side at a relatively narrow interval, and the height positions of the plurality of lighting fixtures attached to the respective lighting baton devices are individually adjusted for each lighting baton device. I am doing so.

According to the lighting baton device of the first embodiment, a slidable second baton can be provided in addition to the first baton with a relatively inexpensive device configuration, and the number of hoisting machines is reduced with respect to the number of baton. And the desired illumination light can be irradiated.

According to the lighting baton device of the second embodiment, when the second baton is not used, the rotating arm can be rotated to store the second baton, and the lighting apparatus can be easily attached to the first baton. .

  According to the lighting baton device of the third embodiment, the second baton can be locked in the suspended position and the storage position, and the problem of inadvertent rotation when using the second baton can be prevented. The trouble that the stored second baton rotates carelessly can be prevented.

  As shown in FIG. 1, the lighting baton device 100 is vertically suspended from a grid-like grid G fixed on the ceiling of a building such as a television studio or a theater. The grid G is fixed with an elevator 102 having a direction changing vehicle for moving the illumination baton device 100 up and down. The elevator 102 simultaneously winds up the four suspension wires 101 (only two are shown in FIG. 1) from which the illumination baton device 100 is suspended at the same speed. That is, the elevator 102 can move the illumination baton device 100 up and down while maintaining a horizontal posture.

  The lower ends of the suspension wires 101 are fixed to the main body frame 110 (main body) of the illumination baton device 100 via suspension arms 112 extending in a substantially vertical direction. Two suspension arms 112 are provided at both ends of the illumination baton device 100 in the longitudinal direction (left-right direction in FIG. 1; first direction). The lower end of each suspension wire 101 is attached to the upper end of each suspension arm 112. Further, the lower ends of the suspension arms 112 are fastened and fixed to the main body frame 110 by screws 114 through L-shaped metal fittings 113 (FIG. 5).

  As shown in FIG. 2, two suspension wires 101 are provided at both ends in the longitudinal direction of the illumination baton device 100 so as to be separated from each other in the device alignment direction (the left-right direction in the drawing; the second direction). Two suspension arms 112 are also provided at each end of the illumination baton device 100. Each of the two suspension arms 112 provided at each end in the longitudinal direction of the illumination baton device 100 is inclined in a direction away from each other in the upward direction along the alignment direction of the illumination baton device 100. In other words, the two sets of suspension arms 112 provided at both ends of the illumination baton device 100 are expanded in the alignment direction toward the ceiling.

  Thereby, the hanging position by the hanging wire 101 of the illumination baton device 100 is expanded in the arrangement direction, the hanging posture of the illumination baton device 100 can be stabilized, and the illumination baton device 100 is hardly shaken in the arrangement direction. be able to. For this reason, when the lighting baton device 100 is moved up and down, it is possible to prevent a problem that interferes with a lighting fixture (not shown) or an art baton (not shown) attached to another adjacent lighting baton device 100 or the like. it can.

  As described above, the lighting baton device 100 vertically suspended from the ceiling is separated by a predetermined distance in the vertical direction and the short direction (second direction) orthogonal to the longitudinal direction (first direction). It is installed side by side and constitutes the lighting equipment for the ceiling. Moreover, an art baton is arrange | positioned between the illumination baton apparatuses 100 as needed. Since the illumination baton device 100 of the present embodiment is provided so that it can be moved up and down independently, a space for arranging an art baton or the like may be provided between two illumination baton devices 100 adjacent in the arrangement direction. it can.

  The lighting baton device 100 of the present embodiment is a device that is used by hooking a lighting fixture on the first baton 20 and the second baton 30, 30 described later, but an acoustic device such as a microphone is attached in addition to the lighting fixture. You can also. Alternatively, a film or panel can be attached to the lighting baton device 100 without using an art baton.

  As shown in FIG. 3, the main body frame 110 of the illumination baton device 100 includes two main frames 110 a that are separated from each other in the lateral direction and extend in parallel to each other in the longitudinal direction. The above-described four suspension arms 112 are fastened and fixed to the upper surface of the main frame 110a near both ends in the longitudinal direction of the main frame 110a. The main frame 110 a extends over substantially the entire length of the illumination baton device 100.

  The main body frame 110 has a plurality of sub-frames 110b extending in the short direction connecting the two main frames 110a. Further, a hollow duct 110 c for wiring is attached to the lower surface side of the main body frame 110. The duct 110c has a length slightly exceeding the entire length of the main body frame 110.

  As shown in FIG. 1, a cable cage 10 for housing a cable (not shown) is provided on the upper surface side of the main body frame 110, that is, the ceiling side. The cable is accommodated in the cable cage 10 in a folded state, and is pulled out from the cable cage 10 as the lighting baton device 100 moves vertically downward. In FIG. 3, the cable cage 10 is indicated by a broken line in order to make the other configuration of the illumination baton device 100 easier to see.

  The lighting baton device 100 is for hanging and supporting a plurality of lighting fixtures (not shown), and therefore it is necessary to connect a cable derived from the ceiling. The cable includes a power supply line for supplying power to a plurality of lighting fixtures (not shown) and a control line for transmitting a control signal for controlling lighting of each lighting fixture.

  As shown in FIGS. 1 and 2, a first baton 20 is suspended from the center of the lower surface side of the main body frame 110 in the short direction. Specifically, the first baton 20 is suspended vertically downward from a lower surface 110d extending in the longitudinal direction of the duct 110c via three support arms 22. The first baton 20 has a length slightly exceeding the main frame 110 a and extends in parallel with the longitudinal direction of the main body frame 110 (first direction). The first baton 20 is fixed to the main body frame 110.

  In the present embodiment, the first baton 20 is suspended from the lower surface 110d of the duct 110c of the main body frame 110 via the three support arms 22 near and in the center in the longitudinal direction. Note that both ends in the longitudinal direction of the first baton 20 have a structure that can be further extended to the outside in the longitudinal direction as indicated by broken lines in FIG. A plurality of outlets 115 are provided on two inclined surfaces 110e inclined in a direction extending upward from the lower surface 110d of the duct 110c.

  When attaching a lighting fixture (not shown) to the lighting baton device 100, a hook (not shown) on the lighting fixture side is hooked on the first baton 20 (or second batons 30 and 30 described later) and the lighting fixture is suspended. Then, a power cord (not shown) of the lighting fixture is inserted into a nearby outlet 115. In the present embodiment, eight outlets 115 are provided apart from each other in the longitudinal direction of the inclined surface 110e, and a total of 16 outlets 115 are provided on both sides of the lower surface 110d.

  However, the number of outlets 115 provided on the two inclined surfaces 110e of the duct 110c can be designed arbitrarily, and varies depending on the length of the illumination baton device 100. Further, the number of outlets 115 can be increased by using a branch tap cord (not shown).

  The illumination baton device 100 according to the present embodiment includes two sets of second batons 30 and 30 in addition to the first baton 20 described above. The second batons 30 and 30 are provided on both sides in the short direction of the illumination baton device 100 with the first baton 20 interposed therebetween, and the two sets of the second batons 30 and 30 have substantially the same structure. . The second baton 30, 30 is provided so as to be able to be deployed and stored with respect to the main body frame 110.

  Each second baton 30 includes two divided batons 30 'and 30' divided into two in the longitudinal direction. That is, the illumination baton device 100 of the present embodiment has a total of four divided batons 30 ′, two on each side with the first baton 20 in between. The number of divisions of the divided baton 30 'can be arbitrarily set. In FIG. 3, the split baton 30 ′ (that is, the second baton 30) is not shown in order to make the other structures easier to see.

In the main body frame 110, four divided batons 30 ′ are independently slid in the lateral direction of the illumination baton device 100, and four sets for rotating between a hanging position and a storage position, which will be described later, are provided. A slide rotation mechanism 40 is provided. Since the four sets of slide rotation mechanisms 40 have substantially the same structure, the following description will be made with one slide rotation mechanism 40 as a representative.

The slide rotation mechanism 40 is a connection of two slide rods 41 and two slide rods 41 that slide in the short direction with respect to the main body frame 110 by connecting the distal ends 42 separated from the main body frame 110 in the short direction. A rod 43, an auxiliary rod 44 provided at the center of the connecting rod 43, and two rotating arms 45 that rotatably connect the divided baton 30 ′ to the tips 42 of the two slide rods 41 are provided. The two slide rods 41, the connecting rod 43, and the auxiliary rod 44 function as slide members.

  The two slide rods 41 are inserted into the main frame 110a via a linear bearing 52 such as a slide bush provided on the front main frame 110a. A slide sleeve 53 that slidably receives the slide rod 41 is provided inside the linear bearing 52 in the short direction. The slide sleeve 53 is bridged between the two main frames 110a. By using the linear bearing 52, the slide rod 41 can be directly moved in the short direction with high accuracy.

  The auxiliary rod 44 passes through the main frame 110a on the front side and is inserted into the slide sleeve 51. The slide sleeve 51 is provided between the pair of main frames 110a. The auxiliary rod 44 functions to prevent the central deflection of the connecting rod 43. The connecting rod 43 extends in parallel with the main body frame 110.

  Thus, when the connecting rod 43 is pulled away from the main body frame 110 from the position indicated by the solid line in FIG. 3, the two slide rods 41 slide in the slide sleeve 53 while being supported by the linear bearings 52, The auxiliary rod 44 slides in the slide sleeve 51. A state in which the connecting rod 43 is pulled out to the position farthest from the main body frame 110 is shown by a broken line in FIG. At the base end of the slide rod 41, a retaining structure (not shown) is provided.

  Conversely, when the connecting rod 43 is pushed in the direction approaching the main body frame 110 from the position indicated by the broken line in FIG. 3, the two slide rods 41 are slid in the reverse direction within the slide sleeve 53 while being supported by the linear bearings 52. The auxiliary rod 44 slides in the slide sleeve 51 in the reverse direction. A buffer member 55 (FIG. 3) for buffering the impact caused by the collision of the slide rods 41 is provided on the main frame 110a on the back side at a position facing the base ends of the two slide rods 41 with the connecting rod 43 pushed. It has been.

The slide rotation mechanism 40 has two rotation arms 45 that rotatably support the divided baton 30 ′ at the tips 42 of the two slide rods 41. The base end of the rotation of each rotation arm 45 is connected to the tip 42 of the corresponding slide rod 41 so as to be rotatable. The split baton 30 ′ is fixed at both ends to the turning tips of the two turning arms 45, and is spanned between the two turning arms 45. The divided baton 30 ′ extends in parallel with the longitudinal direction of the illumination baton device 100 (first direction).

In addition, a lock mechanism 60 that locks the rotation of the rotation arm 45 at two positions is provided at the tip 42 of one slide rod 41 of each slide rotation mechanism 40. The lock mechanism 60 has a suspended position (position indicated by a two-dot chain line in FIG. 2) where the divided baton 30 ′ is suspended vertically downward with respect to the tip 42 of the slide rod 41, and a storage position (FIG. 2). 2, the rotation arm 45 is locked so that the rotation of the rotation arm 45 with respect to the tip 42 is prohibited.

  As shown in FIG. 5, the lock mechanism 60 includes a lock pin 61 provided at the distal end 42 of the slide rod 41, and two (not shown) provided at the rotation base end of the rotation arm 45 corresponding to the lock pin 61. A lock hole and a spring (not shown) that urges the lock pin 61 toward the lock hole are provided. The two lock holes are located at a position facing the lock pin 61 in a state where the rotating arm 45 is rotated to the suspended position, and a position facing the lock pin 61 when the rotating arm 45 is rotated to the storage position. Is provided.

  Thus, when the rotation arm 45 fixed to the storage position is rotated and fixed to the hanging position, the operator pulls the lock pin 61 from one lock hole by pulling the lock pin 61 with one hand. In this state, the split baton 30 ′ is rotated 180 ° with the other hand and pulled down vertically, and the lock pin 61 is released. As a result, the lock pin 61 is inserted into the other lock hole, and the rotating arm 45 is locked in the suspended position.

  On the other hand, when the rotation arm 45 fixed to the hanging position is rotated and fixed to the storage position, the operator pulls the lock pin 61 with one hand and pulls out the lock pin 61 from the other lock hole. In this state, the split baton 30 ′ is turned 180 ° with the other hand, pulled up vertically upward, and the lock pin 61 is released. As a result, the lock pin 61 is inserted into one of the lock holes, and the rotating arm 45 is locked at the storage position.

Note that the slide sleeves 53 containing the slide rods 41 are shifted in the longitudinal direction so that the slide rods 41 of the two sets of slide rotation mechanisms 40 facing in the short direction of the main body frame 110 do not interfere with each other. It is attached. For this reason, the two divided batons 30 ′ facing the short direction of the main body frame 110 are shifted in the longitudinal direction. In the present embodiment, the upper two divided batons 30 'are arranged close to the center in FIG. 3, and the lower two divided batons 30' are arranged apart from each other in FIG.

  In addition to this, a method of preventing interference of the slide rod 41 by making the length of the split baton 30 ′ different on both sides in the short direction of the main body frame 110 can be considered, but the split batons 30 ′ (and It is necessary to create and store and manage the connecting rods 43) having different lengths, which increases manufacturing costs and management costs. On the other hand, as in the present embodiment, the divided baton 30 ′ (and the connecting rod 43) has one length by shifting the divided baton 30 ′ in the longitudinal direction on both sides in the short direction of the main body frame 110. Manufacturing costs and management costs can be reduced.

  Further, the second baton 30, that is, the divided baton 30 'can be stored in a state shown by a solid line in FIG. FIG. 1 shows a state in which the second baton 30 is stored. In this state, the two second batons 30 are unusable, and the outer shape of the illumination baton device 100 is the smallest. In operation using only the first baton 20, the two second batons 30 are arranged in this state.

  In this state (the state in which the second baton 30 is housed), in addition to the first baton 20, a lighting fixture can be attached to the connecting rod 43 that can be separated from the main body frame 110 in the short direction. . In this case, the first baton 20 and the connecting rod 43 are stepped in the vertical direction, and the illumination light attached to the first baton 20 and the illumination light attached to the connecting rod 43 do not interfere with each other, and more A luminaire can be attached.

  In addition, if the 2nd baton 30 is arrange | positioned in the storage position shown as a continuous line in FIG. 2, attachment of the lighting fixture with respect to the 1st baton 20 can be made easy. If the second baton is rotated to the hanging position indicated by a two-dot chain line in FIG. 2, the second baton 30 is located on both sides in the short direction of the first baton 20, so It interferes with the installation of lighting equipment. On the other hand, if the second baton 30 is flipped up to the position indicated by the solid line in FIG. 2, it becomes easy to hook the lighting fixture on the first baton 20 and the lighting fixture can be easily attached to the connecting rod 43. Can be improved.

  On the other hand, when the second baton 30 is unfolded and used, first, the lock by the lock mechanism 60 is released from the storage state shown by the solid line in FIG. Rotates to the lowered position. Then, from this state, the connecting rod 43 is pulled outward in the short direction, and the second baton 30 is pulled out to the unfolded position indicated by the broken line in FIG. At this time, the connecting rod 43 can be pulled out to a desired length, and does not need to be pulled out to the maximum width in the lateral direction.

  When storing the second baton 30 in the unfolded state, first, the connecting rod 43 is pushed inward in the short direction from the unfolded state shown by the broken line in FIG. 2, and the state shown by the two-dot chain line in FIG. Shrink to Then, from this state, the lock by the lock mechanism 60 is released, and the second baton 30 is rotated to the storage position indicated by the solid line in FIG.

  If the second baton 30 is to be rotated with the connecting rod 43 pulled out to the position indicated by the broken line, a relatively large space is required for the rotation of the second baton 30, and adjacent illumination is required. It will become easy to contact the lighting fixture of the baton apparatus 100. FIG. For this reason, it is desirable to rotate the rotation arm 45 in a state where the connecting rod 43 is brought close to the main body frame 110.

  As described above, according to the lighting baton device 100 of the present embodiment, in addition to the first baton 20, the two second batons 30 can be developed and used, so that they are attached to one lighting baton device 100. The number of lighting fixtures that can be used can be increased, and convenience can be improved. Further, according to the present embodiment, for example, lighting fixtures can be distributed and arranged, and the lighting effect can be varied.

  On the other hand, the lighting baton device 100 can be slimmed by storing the second baton 30 on both sides, and the degree of freedom of layout of the lighting baton device 100 can be further increased. That is, according to the present embodiment, the illumination baton device 100 can be stored compactly and used linearly, and can also be deployed and used planarly, and can be operated according to the purpose of use. .

  In addition, since the number of lighting fixtures that can be attached to one lighting baton device 100 can be increased, the number of elevators 102 can be reduced as the entire lighting equipment, and the weight of the entire lighting equipment can be reduced. The load applied to the ceiling portion can be reduced, and the manufacturing cost of the entire lighting equipment can be suppressed.

  Further, according to the present embodiment, only the first baton 20 can be used, and a plurality of (four in the present embodiment) divided batons 30 ′ can be selectively used. All of the batons 20 and 30 can be used, and further, the connecting rod 43 can be used as a baton, and the application of the lighting baton device 100 can be expanded. Furthermore, the 1st baton 20 can also be extended and the number of the lighting fixtures which can be attached can also be increased.

  Moreover, according to this embodiment, since the 2nd baton 30 of both sides can be expand | deployed, it is not necessary to use a transfer baton conventionally, and convenience can be improved. That is, since no passing baton is used, each lighting baton device 100 can be moved up and down independently, and an art baton or the like can be arranged between the lighting baton devices 100. The degree of freedom can be further increased.

Moreover, according to this embodiment, in addition to being able to arbitrarily set the height of the lighting fixture by moving the lighting baton device 100 up and down, the protruding and retracting state of the slide rod 41 of each slide rotation mechanism 40 can be arbitrarily set. Therefore, the freedom degree of the layout of a lighting fixture can be raised more. In addition, since the lighting baton device 100 can be moved up and down independently, a space for arranging an art baton or the like can be provided between the lighting baton devices 100, and the degree of freedom in the layout of the art baton can be increased. .

  Furthermore, according to the present embodiment, the divided baton 30 ′ arranged at the storage position can be locked, and the trouble that the stored divided baton 30 ′ rotates inadvertently can be prevented, and it is damaged by hitting a lighting fixture or the like. Problems can be prevented. In addition, the divided baton 30 ′ disposed at the hanging position can be locked, and the inconvenience that the luminaire moves inadvertently when the divided baton 30 ′ is used can be prevented.

[Example]
Whereas conventional illumination baton devices (having only one baton) are generally arranged side by side at a 1500 mm pitch, which is considered easy to use, the illumination baton device 100 of the above-described embodiment Arranged at a pitch of 1900 mm along the alignment direction. In this case, although there is a difference in pitch of 400 mm, the illumination baton device 100 of the present embodiment has two second batons 30 (four divided batons 30 ′), so that this pitch difference can be complemented. it can.

  That is, the illumination baton device 100 of the present embodiment has a width in the short side direction of 600 mm when it is in the most compact state in which the two second batons 30 are accommodated, and a length that allows each second baton 30 to be extended. Therefore, the second baton 30 can be arranged at an arbitrary position between 300 mm and 600 mm on both sides in the short direction around the first baton 20. For this reason, the pitch difference of 400 mm mentioned above can be supplemented.
