Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a movable floor platform for the audience seats in equipment for changing the shape of the relationship between the stage and audience seats (referred to as stage format) in a theater or the like. This relates to theater equipment that realizes various stage formats by combining a seating wagon (also called an audience wagon) and a pedestal mechanism installed on the theater floor.

(Summary of the Invention) This invention combines an audience seat wagon and a truss mechanism provided on the floor of the theater for the purpose of freely and easily changing the stage format of the theater depending on the program and production intention. In order to realize this, the passenger wagon is made into standard dimensions and consists of an upper surface in the form of a stepped floor on which several rows of passenger seats can be mounted horizontally and several rows vertically, and a lower surface equipped with wheels or sleds for movability. On the other hand, near the entire surface of the theater floor is divided vertically and horizontally with reference dimensions common to or related to the audience seat wagons, and each divided section is constructed with a sliding mechanism that moves up and down independently. When the passenger seat wagons are stored, they are placed under the floor of the individual sliding mechanisms, and when in use, the individual passenger wagons can be taken out onto the floor of the individual sliding mechanisms and arranged in any position and in any direction. The purpose is to provide theater floor sliding mechanism equipment.

(Prior Art) Generally speaking, some stage formats in theaters exhibit a correlated shape between a stage section 11 and an audience seat section 12 as shown in FIG. These are called end stage format a, thrust stage format b, and arena stage format c. A recent trend is to make it possible to use these various formats depending on the performance and production intention, even within a single theater space. There is a need to provide a mechanism that allows changes or replacement.

Conventional techniques for achieving this purpose include providing seats for the audience individually or in the form of several chairs connected horizontally as portable chairs, and arranging them on the floor in a space designated for the audience area as necessary. There is something. Also, depending on the time and circumstances, it may be necessary to temporarily remove some or all of the chairs from the theater, but in that case they will be stored in a warehouse located at an appropriate location.

In order to achieve some of the above objectives, we have developed a multi-division auction mechanism for the floor of theaters, etc., a mechanism in which the audience seats are movable by means of a wagon, and a mechanism in which the audience seats are directly mounted under the floor of the auction without the use of a wagon. However, technologies such as a mechanism that vertically rotates and sets it on the floor when necessary, and a mechanism that allows the front part of the audience seats to be moved and stored under the fixed floor at the rear of the audience seats to expand the stage area. Each of them already exists.

(Problems to be Solved by the Invention) When attempting to obtain various variable stage formats using such conventional techniques, there are the following problems.

(1) In order to give the audience a good sight line, the cross-sectional shape of the audience seating area should be made up of tiered floors for each row of chairs, that is, the front and back spacing is, for example, approximately 1.0 m apart.
Moreover, depending on the stage format you choose, you may want the rows of chairs to be oriented vertically (in the x direction in Figure 1).
There may be cases where you want it to be horizontal (perpendicular to the paper in Figure 1). Therefore, it is conceivable to ideally divide the theater floor surface into sections of 0.9 to 1.0 m both vertically and horizontally, using a multi-segmented shedding mechanism. However, it is technically and economically impossible to divide the auction mechanism into such small sections over almost the entire surface of the theater floor, and it is not practical.

(2) Depending on the stage format you choose, there will be unnecessary chairs or wagons for the audience. A warehouse or space to accommodate this must be provided outside the theater space. As a result, construction costs will increase,
Restrictions also tend to arise in the mutual layout of the theater space and attached spaces such as the lobby and dressing rooms.

(3) With a mechanism in which the existing seats are mounted directly under the floor of the auction and set on the floor by vertical rotation or other methods when necessary, or in which the front part of the seats is stored under the fixed floor at the rear of the seats, the chairs are The direction of the columns is fixed, and you cannot freely make them vertical or horizontal.

Therefore, an object of the present invention is to solve the above-mentioned problems and to make it possible to extremely easily obtain a variety of almost perfect stage formats within one theater space at a relatively low construction cost. The purpose is to provide a theater floor sliding mechanism with a built-in audience seat wagon.

(Means for Solving the Problems) In order to achieve this object, the auction seat wagon built-in auction mechanism equipment for theaters according to the present invention is designed to make the relationship between the stage section and the audience seats in the theater variable. In the theater format variable equipment configured by combining a movable floor platform for the seating section and a truss mechanism provided on the theater floor, each of the plurality of movable floor platforms for the audience seating section is
It has a tiered floor structure with standard dimensions that can accommodate several rows of audience seats horizontally and several rows vertically, and a sliding mechanism installed on the theater floor extends near the entire surface of the floor vertically and horizontally. The equipment is constructed by dividing the base into parts having standard dimensions that are common to or related to the base, and each divided part moves up and down independently. When storing the movable floor base for the passenger seat section, it is placed under the floor of each of the above-mentioned sling mechanisms, and when in use, the movable floor base for the sate section is taken out onto the floor of each of the above-mentioned swivel mechanisms, and placed in a desired position and in a desired orientation. The feature is that a predetermined theater format is obtained by arranging the theaters.

(Examples) The present invention will be described in detail below by way of examples with reference to the accompanying drawings.

FIGS. 1A to 1D are schematic cross-sectional views of the theater floor and its surroundings in an embodiment of the present invention, and are shown for convenience in explaining the stage format creation operation procedure. The auctions 21, 22, 23, 24, and 25 can each move up and down independently, and each has a storage space under the floor in which passenger wagons 26, 27, 28, and 29 can be stored.

As mentioned above, the passenger seat wagon referred to here refers to the "standard movable floor platform for the passenger seat area" (unit wagon for the passenger seat area) that has been made into standard dimensions (modularized) with a stepped floor-shaped structure according to the present invention. There is, and it is abbreviated as passenger wagon.

Figure 1a shows the passenger wagons 26 to 29 stored in the passenger wagon storage spaces of the auctions 21 to 24, and Figure 1b shows the passenger wagons 26 to 29 stored in the storage spaces of the passenger wagons 21 to 24.
1, 22, and 23 vertically relative to each other, and
The passenger wagons 26 and 27 stored under the floor of 22 are placed in separate adjacent auctions 22 and 2, respectively.
3 shows the state where it has been moved onto the floor. At this time, if necessary, it is also possible to move the direction of the passenger wagon onto the floor and then horizontally rotate it 90 degrees or 180 degrees, or move the wagon up and down again and then move it back onto the original floor. It is also possible to do so.

Finally, adjust the relative position of the front edge,
A stage format as illustrated in FIG. 1c or d can be obtained. In the case of Figure 1 c, the auction 21 is the stage part and the remaining auctions are the audience seat part. In the case of Figure 1 d, the auction 23 is the stage part and the remaining auctions are the audience seat part. For example, the end stage format [Figure 3 a] and the arena stage format [Figure 3 c] are used, respectively. Further, FIG. 1c is also a sectional view of the longitudinal centerline portion of the thrust stage type shown in FIG. 3b. Since the individual passenger wagons and floor rails are constructed with common or closely related standard dimensions, they are modularized and can be combined to form a combination of equipment based on their dimensions and structure. Therefore, the above-mentioned operations can be performed extremely smoothly, and various stage formats can be easily realized.

To explain the standard dimensions, for example, as shown in the specific example below (see Figure 2),
The standard plane dimensions of the main body of the passenger wagon, which can accommodate three rows of seats vertically, are (width) 1.35 m x (vertical) 2.70 m, or (width) 1.5 m, as an example of design values. m x (vertical) 3.0 m (that is, it has an integer multiple or simple integer ratio of 0.9 m or 1 m). Note that the shape of the plane with standard dimensions is not limited to a square, but may have closely related dimensions based on a simple integer ratio, for example, a rectangle with a ratio of 1:2 may of course be used. As a design example, the standard dimensions of the edge of the floor division
Compared to the 3.0m x 3.0m, the dimensions of the passenger wagon itself are half the size, 1.5m x 3.0m.

In FIG. 1, the horizontal and vertical directions of the passenger wagon refer to the vertical direction and the horizontal direction x, respectively, to the plane of the paper.

Although the explanation is a little confusing here, I will refer to the form of the passenger wagon. Figures 2a to 2c show various embodiments of passenger wagons. In each of the figures a, b, and c, the upper row shows a plan view seen from above, the left side of the lower row shows a front view, and the right side of the lower row shows a side view. The form of the individual passenger wagon according to the present invention is as shown in FIG.
In principle, the passenger seat wagon body 32 has a tiered floor shape that can be installed in multiple rows (three rows in these figures) in the vertical direction. In actual applications, there are special cases such as the main body 32 with no step difference in the floor as shown in Figure 2c, and there are also cases where the main body 32 has a stepped floor but no chairs are attached, and is used only for vertical aisles in the seating area. There are some things. These can be used in combination as appropriate to construct a practical theater seating area.

In either case, each passenger wagon has a structure separate from the auction so that it can be moved forward, backward, left, right, or rotated horizontally by human or mechanical power, and is equipped with wheels or sleds around the bottom as necessary. Installing. It should be noted that in FIG. 2, the passenger wagon is shown separated into a passenger chair 31 and a passenger wagon main body 32. That is, from the wagon main body 32 to the passenger seat chair 31
If the seats are designed to be easily removable, some of the seats can be removed to create vertical or horizontal aisles when necessary, further increasing the flexibility in configuring the seats.

In Figures 1c and d, the stage section is shown as consisting of one auction 21 or 23 (or one row of auctions), but generally it is composed of multiple rows of auctions. It's normal. Safety considerations will also need to be taken, such as installing side aisles within the audience seats and various stoppers. However, since these do not pose any particular problems in implementing the present invention, and rather complicate the explanation, these parts are omitted in the drawings.

(Effects of the Invention) The first effect of this invention is its economy. If near the entire surface of the theater floor were to be constructed with an ideal subdivided multi-segmented sled mechanism, it would not be technically impossible to make the sills divided into units of, for example, 0.9 to 1.0 m square. However, it costs a huge amount of money. In this invention, it can be made approximately 2 to 4 m square, so the number and cost of the warps can be kept within a reasonable range (in the ratio of 1 m square to 3 m square,
(The number of auctions required is approximately 1/10). Furthermore, the production cost of the passenger wagon is only a few percent of the total cost.

The second effect is the physical and
This means that physiological and psychological conditions can always be maintained in near perfect conditions. In other words, you can freely choose the dimensions of the tiered floor and the orientation of the seats, as well as the shape and grade of individual chairs.

The third effect is that there is no need for a chair storage warehouse. This not only saves on construction costs for warehouses, but also allows for further enrichment of other essential theater spaces, such as lobbies and dressing rooms.
