Description

  The present invention relates to a baton device, and more particularly, to an improvement of a baton device that forms a grit with a main baton and a transfer baton.

  In general, many batons, such as pipe bodies, are arranged almost horizontally in the same row near the ceiling above the stage of a theater or the like, and baton devices that suspend lighting fixtures etc. are often used on this baton. ing.

  And when many lighting fixtures etc. are hung, for example, in patent document 1, in order to increase a holding place, a frame body is separately hung by a baton, and lighting fixtures etc. are made to this frame body. A baton device intended to suspend the hood is disclosed.

Therefore, according to the baton device disclosed in Patent Document 1, the frame body is suspended from the baton when necessary, and when it is not necessary, a predetermined stage such as a sleeve stage adjacent to the stage is provided. By storing the frame body in the storage place, it is possible to use the frame body more effectively than when the frame body is always suspended by the baton.
Japanese Patent Laid-Open No. 9-265804 (Claims Claims 1, Paragraphs 0002, 0004, 0005, 0009 to 0012, FIGS. 1 and 2)

  However, it may be pointed out that it is difficult to provide the baton device disclosed in Patent Document 1 described above not in a space near the ceiling above the stage in the theater but in a space near the ceiling in the studio, for example.

  That is, for example, even in a television broadcasting studio, lighting equipment is distributed in a space close to the ceiling to ensure necessary lighting. In many of the television broadcasting studios, the above space is a space above the stage in a theater. Compared to the above, the ceiling is low, that is, narrow.

  Therefore, even if an attempt is made to provide the baton device disclosed in Patent Document 1 in a space close to the ceiling in this studio, the so-called space becomes insufficient, and its realization becomes difficult.

  Therefore, a large number of main batons arranged in one direction at a horizontal plane facing each other so as to be close to the ceiling surface in a space close to the ceiling in the studio, and a direction crossing the main batons A baton device has been proposed which forms a grit for suspending a lighting fixture or the like with a large number of spare baton arranged in the other direction. At this time, the baton is connected so as to be separable. It is said that it will be distributed to the necessary places as needed.

  Therefore, in the baton device that forms a grit with the main baton and the handing baton, the number of handing baton can be increased or decreased, and by selecting the location of the baton, the required lighting equipment can be increased or decreased. Will get.

  However, at this time, whether or not the delivery baton is distributed as prescribed, that is, whether it is maintained in a state in which a lighting fixture or the like can be suspended, depends on visual recognition from below the baton device. It is not easy, and if the passing baton is not linked in a predetermined manner, there is a risk that the passing baton may come off the linked place and drop many lighting fixtures.

  This invention was devised in view of such a current situation, and its purpose is to form a grit with a main baton and a passing baton to increase the hanging place such as a lighting fixture, It is an object to provide a baton device that can easily confirm the connection state of the passing baton, can realize a safe use state of the passing baton, and is optimal for expecting an improvement in versatility.

  In order to achieve the above-described object, the configuration of the baton device according to the present invention basically includes a large number of existing main batons arranged in one direction at a horizontal plane position facing the ceiling surface, and the main batons. In a baton device in which a grit for suspending a lighting fixture or the like is formed with a number of passing batons arranged in the other direction crossing the main baton, the main baton is suspended by a guide member disposed above it. Further, it is assumed that the guide member has pressure-sensitive means on its upper surface, and the transfer baton is detachably spanned by the guide member with its both ends contacting the pressure-sensitive means.

  More specifically, the pressure-sensitive means is a tape switch, and the guide member has a flat surface that allows the pressure-sensitive means to be fixed on the upper end surface and is suspended from a ceiling surface or the like. Suppose that it is suspended.

  Therefore, in the present invention, when a grid for suspending a lighting fixture or the like is formed by the main baton and the passing baton, the passing baton is hung on the guide member for suspending the main baton. Since the pressure-sensitive means distributed on the member senses that the passing baton is hung on the guide member, knowing this, for example, the passing baton from the lower side of the baton device on which the luminaire is suspended is predetermined. Thus, it is not necessary to confirm whether or not it is bridged on the guide member by a technician, that is, it is not necessary to confirm by relying on the eyes of a technician or the like.

  As a result, according to the present invention, when the grit is formed by the main baton and the passing baton to increase the hanging place such as the lighting fixture, the state where the passing baton is reliably spanned can be easily confirmed. Therefore, it is possible to realize a safe use state of the passing baton, and it is optimal for expecting an improvement in versatility of the baton device.

  Hereinafter, the present invention will be described based on the illustrated embodiment. The baton apparatus according to the present invention is assumed to be distributed in a space near a ceiling surface in a studio for television broadcasting, for example, as shown in FIG. As shown in FIG. 2, the main baton 1 and the transfer baton 2 form a grit (lattice-like body) G for suspending the luminaire S or the like. At this time, the guide member 3 and the pressure-sensitive means 4 are illustrated. It is said that it has.

  To explain a little, the main baton 1 has an appropriate length and mechanical strength that allows the lighting fixture S or the like to be suspended, and is made of, for example, a pipe body and is opposed to a ceiling surface (not shown) while being adjacent from below. It is assumed that many are arranged in one direction substantially horizontally at a horizontal plane position.

  At this time, the main baton 1 is not shown in detail, but in many cases, it is located in a space close to the ceiling surface of the studio and is arranged in the horizontal direction. It is assumed that it is formed longer than the passing baton 2.

  On the other hand, the passing baton 2 is basically configured in the same manner as the main baton 1 described above, and of course allows the lighting fixture S to be suspended. In this case, a large number are arranged substantially horizontally in the other direction, ie, the direction crossing this.

  From this, the delivery baton 2 is formed to be much shorter in length than the main baton 1 described above, and in particular, the refilling operation for changing the place of delivery is facilitated. For example, on the basis of 900 mm which is a basic dimension in a building, it will be formed to a length that is an integral multiple thereof.

  However, in the present invention, the passing baton 2 is not directly linked to the main baton 1, but is linked so as to be bridged over a guide member 3 described later.

  That is, as described above, the main baton 1 suspends the lighting fixture S and the like, and at this time, it is unclear at which position in the main baton 1 the lighting fixture S is suspended. This is because the selection of connecting the main baton 1 and the baton 2 so as to be directly bridged is assumed to be impossible in some cases, and may be impractical.

  On the other hand, the main baton 1 described above is suspended from a guide member 3 disposed above the main baton 1, and the guide member 3 is suspended from the ceiling surface. The suspension member 5 is suspended.

  At this time, as shown in FIG. 2, the suspension member 5 suspends the baton wire rod 6, and the guide member 3 is suspended on the baton wire rod 6.

  Further, although the suspension member 5 is suspended from the ceiling surface, the suspension member 5 may be suspended from, for example, a kite that is arranged below the ceiling surface. .

  As described above, when the hanging member 5 is suspended from the cage, it is possible to distribute the baton device according to the present invention in a space close to the ceiling above the theater stage. In other words, it can be said that it may be embodied above the theater stage.

  The baton wire rod 6 suspends a large number of plugs 61 that enable energization of the luminaire S or the like to a so-called main body, and is not shown, but is a lead wire that connects the plug 61 to the inner space of the main body. In particular, in the present invention, it is possible to accommodate a lead wire that is electrically connected to the pressure-sensitive means 4 described later.

  By the way, the guide member 3 is assumed to suspend the main baton 1 using the tightening type suspending band 31 as shown in the figure, but the main point is that the main baton 1 is horizontally arranged at a predetermined height position. Any configuration may be adopted as long as it exists.

  However, the main baton 1 suspends the luminaire S and the like, and considering that the luminaire S has so-called directivity, the guide member 3 is formed in a tightening shape as described above. Thus, it can be said that it is preferable that the main baton 1 is suspended in such a manner as to prevent the main baton 1 from rotating.

  Further, the guide member 3 in the present invention is configured to fix the pressure-sensitive means 4 to the upper end surface, and is configured to have a flat surface for the upper end, and in the drawing, the cross section is rectangular. It is assumed that the pressure sensing means 4 is provided on the flat surface which is the upper end surface.

  From the above, the guide member 3 may be of any configuration as long as the pressure-sensitive means 4 can be fixed to the upper end surface, but as described above, the main baton 1 is suspended, And in view of enabling the transfer baton 2 to be bridged, it is to be avoided that it is composed of a flexible structure such as a chain or a wire. I will.

  Further, it can be said that the guide member 3 may be made of, for example, a frame body having a honeycomb structure in addition to the pipe body in order to avoid an unnecessarily increase in the total weight in the baton apparatus.

  Next, the pressure-sensitive means 4 is composed of a tape switch as shown in the figure. As described above, the pressure-sensitive means 4 is fixed to the upper end surface of the guide member 3 and is switched on by a load acting on the upper end surface. It is said.

  That is, as shown in FIG. 2, the transfer baton 2 has hook-shaped hooks 21 integrally at both ends by welding or the like, and the hooks 21 are connected to the upper end surface of the guide member 3. The hook 21 is brought into contact with and presses the tape switch as the pressure-sensitive means 4 when it is hooked on the tape.

  Then, the fact that the passing baton 2 is in contact with and pressing the tape switch via the hook 21 can be known by, for example, a controller via a lead wire connected to the tape switch.

  Further, since the tape switch is configured to be switched on when a predetermined load is applied, if the transfer baton 2 is not accurately in contact with the guide member 3, that is, the tape switch, Therefore, it is possible to clearly know by mechanical means that the passing baton 2 is not linked to the guide member 3 accurately.

  As described above, according to the present invention, the engineer determines whether or not the passing baton 2 is hung on the guide member 3 in a predetermined manner from below the baton device on which the lighting fixture S or the like is suspended. It is no longer necessary to check with the eyes of a person such as an engineer. As a result, a grit G is formed by the main baton 1 and the handing baton 2 to hold the lighting fixture S or the like. When the transfer baton 2 is increased, it is possible to easily confirm the state in which the delivery baton 2 is reliably spanned and to realize a safe use state of the delivery baton 2.

It is a perspective view which shows partially the baton apparatus by this invention. FIG. 6 is an enlarged partial view showing a state where a passing baton is stretched over a guide member.
