Description

In the present invention, the seat arrangement is changed while newly installing a table between the seats adjacent to the aisle direction of the existing spectator seats having an inclination that raises the height of the floor from the front to the rear. It is about how to change seats.

When trying to install a new table between the seats adjacent to the aisle direction of the existing spectator seats that are formed in a staircase shape with a slope that raises the floor height from the front to the rear, the aisle direction The seats for a plurality of stages adjacent to the seat will be rearranged to a smaller number of seats (see Patent Document 1). This is due to the inability to change the form of the skeleton itself, to which the seats are fixed. The front refers to the field side where the audience faces, and the rear refers to the opposite side.

In Patent Document 1, the floor is arranged while maintaining a constant distance between seats from the existing spectator seats in which the distance between floor surfaces arranged with a certain distance in the passage direction and the distance between adjacent seats are equal. The seats have been changed to spectator seats where the distance between seats is larger than the distance between faces. In this example, the existing floor is used as a footrest when the spectator sits in the newly installed seat, but there is no regularity between the new adjacent seats and the floor, and the space between the seats is irregular. Since the distance between the floor and the floor is not the same, the floor may not be usable as a footrest (paragraph 0018).

In Patent Document 1, the distance between adjacent seats after the installation of a new seat is increased from the distance between existing seats to secure a sufficient space between the new seats, but the distance between the new seats is secured. Since there is no regularity between the floor and the floor, it is difficult to install the table regularly when trying to install a new table.

By switching the state of the aisle board that is rotatably supported around the horizontal axis and integrated with the additional seats between the adjacent seats in the aisle direction, the additional seats can be taken in and out between the adjacent regular seats. There is also a method (see Patent Document 2).

Japanese Patent No. 5166301 (Claim 1, Claim 2, paragraphs 0013 to 0019, FIGS. 1, 2) Japanese Unexamined Patent Publication No. 7-279457 (paragraphs 0012 to 0014, FIGS. 4 to 7)

However, Patent Document 2 does not change the existing distance between seats, nor does it correspond to the installation of a new table.

Based on the above background, the present invention proposes a method for changing the seats of spectators' seats, which can accommodate the installation of a new table while changing the distance between existing seats.

The method for changing the seats of the spectators'seats according to claim 1 is that the seats of the spectators' seats are adjacent to the aisle direction in the existing spectators' seats having a slope that rises stepwise on the upper surface of the existing old floor from the front to the rear. It is a seat change method that changes the seat arrangement while newly installing a table on the old floor of at least three steps.
The table is installed on the upper surface of the two steps of the old floor on the front side of the upper surface of the old floor of the three steps adjacent to the passage direction, and the old floor of the two steps on the front side. It is a constituent requirement that a new seat is newly installed on the front side of the table on the upper surface of the old floor portion on the rear side of the upper surface.

"Front" refers to, for example, the field side or the stage side to which the audience faces as described above, and "rear" refers to the opposite side. "There is a slope in which the height of the upper surface of the old floor rises from the front to the rear" means that it goes up from the front side to the rear side and goes down from the opposite side. The "passage direction" is a direction in which the upper surface of the stepped old floor portion 2 is raised and lowered. The upper surface of the old floor portion 2 is the old floor surface 3. Hereinafter, the upper surface of the old floor portion 2 is also referred to as the old floor surface 3. There are spectator seats for outdoor or indoor stadiums such as athletics stadiums and soccer fields, and spectator seats for indoor theaters.

As shown in FIG. 1, the step h between the three steps of the old floor surface 3 and 3 adjacent to the passage direction and the width w of the upper surface (old floor surface 3) of the old floor portion 2 are basically the same, but not necessarily. no need to do that. The width of the old floor surface 3 is basically equal to the width of the old floor portion 2. Hereinafter, the width of the upper surface of the old floor portion 2 (old floor surface 3) is also referred to as the width of the old floor portion 2. The "width of the upper surface of the old floor portion" is the depth of the old floor surface 3 in the passage direction.

The "old floor 2 having at least 3 steps arranged in the aisle direction" is an existing old floor 2 having at least 3 steps continuous in the aisle direction for which the table 6 is newly installed. This means that the floor 2 will be changed to a new two-tiered new floor 8 (new spectator seats 9) after the table 6 is installed.

"Changing the seat arrangement" in claim 1 means that the arrangement state of the old seats 5 and 5 originally installed (supported) on the old floor 2 is removed from the newly installed new seat 7. It means to change to the arrangement state of the new seat 7 after the change to the new floor 8 including the old seat 5 which is used as the new seat 7 without being used. The "new seat" in claim 1 includes the existing old seat 5 used as the new seat 7.

Speaking of the case where the width w of each of the three consecutive old floors 2 is equal, the dimension 3w that is three times the width w of the old floor 2 for one step is the new floor 8 for the new two steps. (3w = 2W), the width W of the new floor portion 8 for one step is larger than the width w of the old floor portion 2 and smaller than twice (w <W <2w). When the width W of each new floor portion 8 of the two stages is equal (W1 = W2), the width W is 1.5 times the width w of the old floor portion 2 (W = 1.5w), but 2 When the width W of the new floor portion 8 for the steps is different (W1 ≠ W2), the widths W1 and W2 of the new floor portion 8 are larger than the width w of the old floor portion and smaller than twice (w <W1 (W2)). ) <2w). For example, if w = 800 mm and W1 = W2, then W1 = W2 = 1200 mm.

In either case, the width W of the new floor portion 8 is larger than the width w of the old floor portion 2, so by using this difference in width (W-w), the adjacency after the change to the new spectator seat 9 A space for installing the table 6 is secured between the new seats 7 and 7 of the two-tiered new floors 8 and 8. The "new seat 7 after the change to the spectator seat 9" here includes the old seat 5 which has not actually been changed to the new seat 7 as described above.

For this reason, as the table 6 is installed, the space between the legs of the spectators seated in the new seat 7 or the old seat 5 when it is used as a new seat without being replaced may be narrowed. Be avoided. As a result, while changing the distance between the existing old seats 5 and 5, the spectators are released from the feeling of blockage that they receive in the seated state due to the new installation of the table 6, and the feeling of openness and security in the seated state is secured. To.

From the fact that the total width w of the old floor portion 2 for the three stages is 3w, and the total width W of the new floor portion 8 for the two stages is 2W (3w = 2W), the following can also be said. As shown in FIG. 1, for example, when the floor plate 62 is integrated with the table 6 installed on the frontmost old floor portion 2 of the three-tiered old floor portions 2 arranged in the passage direction (claim 2). ), The step H1 between the upper surface of the floor plate 62 and the old floor surface 3 on the front stage side thereof, and the step H2 between the upper surface of the floor plate 62 and the old floor surface 3 on the subsequent stage side are the old ones before the seat change. It can also be 1.5 times the step h between the floor surfaces 3 and 3. In that case, H1 = H2. This means that the field of vision of the spectators seated in the new seat 7 on the rear stage side is less likely to be obstructed by the spectators seated in the new seat 7 on the front stage side, and the field of view downward is widened.

The table 6 is installed and fixed on the old floors 3 and 3 of the two old floors 2 and 2 on the front side of the old floor 3 of the old floor 2 of the three steps adjacent to the aisle direction. .. As shown in FIG. 2, of the old floor surface 3 of the adjacent three-tiered old floor portion 2, the table 6 (partition plate 61 described later) installed on the old floor surface 3 of the frontmost old floor portion 2. If the legs are aligned with the front portion of the old floor surface 3, the width of the old floor surface 3 of the old floor portion 2 in the front stage can be effectively used as the new floor portion 8.

The adjacent three-tiered old floor portion 2 is changed to the new floor portion 8 by, for example, installing (arranging) the floor plate 62 described later on the front-stage old floor portion 2. For this reason, for spectators who use the new floor 8 as a passage (footrest), the old floor 2 on the rear side (middle) of the old floor 3 of the old floor 2 on the front side 2 steps. A new seat 7 will be installed on the front side of the table 6 on the old floor surface 3. Of the old floors 3 of the adjacent three-tiered old floor 2, the old seats 5 installed on the last-tiered old floor 3 do not affect the installation of the newly installed table 6, so the seats It can be used as it is even after the change. However, the old seat 5 may be replaced with a new seat 7.

Of the old floors 3 of the adjacent three-tiered old floors 2, the table 6 installed on the old floors 3 of the frontmost old floors 2 is for spectators seated in the newly installed new seats 7. It can also be used for the purpose of installing a passageway or a footrest. For example, the table 6 is integrated with the partition plate 61 for partitioning the space between the new seat 7 adjacent to the front side in the aisle direction or the existing old seat 5 and the rear side in the aisle direction of the partition plate 61. By providing the floor plate 62 overhanging (claim 2), the floor plate 62 can be used as a new passage (floor surface) or a footrest. The “integration” includes a case where the floor plate 62 is integrally formed with the partition plate 61 and a case where the floor plate 62 is integrated as a result of joining (fixing). The "existing old seat 5" refers to the old seat 5 used as the new seat 7 as described above.

In this case, if the floor plate 62 only abuts on the front surface (side surface) 4 of the old floor portion 2 on the rear side or has a width enough to abut (claim 3), the floor plate 62 is used as a new passage (floor surface). It will be possible. "Width to the extent that it abuts" means that even if the floor plate 62 does not abut on the front surface 4 of the old floor portion 2 and a gap may occur between the floor plate 62 and the old floor portion 2, the gap may pass or pass through. It is said that the size is such that there is no problem when using it as a footrest. When a gap is formed between the floor plate 62 and the old floor portion 2, the old floor portion 2 side of the floor plate 62 is supported by the old floor portion 2 under the floor plate 62 via a support material or the like.

In claim 3, the floor plate 62 of the new table 6 installed on the same old floor surface 3 as the old floor surface 3 on which the new seat 7 is installed is placed on the old floor portion 2 of the (last stage) adjacent to the rear side. If it is equal to the height of the floor surface 3, the floor plate 62 is made continuous with the old floor surface 3 of the old floor portion 2, a new upper surface (new floor surface) of the new floor portion 8 is formed flat, and a passage (footrest) is formed. ) Can be expanded.

The difference between the width W of the new floor and the width w of the old floor (W-w) is to change the old floor of at least three steps adjacent to the aisle direction to the new floor of two new steps after the table is installed. ), It is possible to secure a space for installing a table between the new seats on the adjacent two-tiered new floor. Therefore, with the installation of the table, the distance between the table and the foot of the spectator seated in the new seat will not be narrowed, and the spectator will be seated by installing a new table while changing the existing distance between the old seats. It is possible to secure a feeling of openness and a sense of security in the seated state by being released from the feeling of obstruction.

It is a vertical cross-sectional view showing the existing spectator seats having the same width of the upper surface of the old floor part of at least three steps arranged adjacent to each other in the aisle direction. It is a vertical cross-sectional view showing the audience seats after changing the old floor part of three steps to the new floor part of two steps after installing the table.

FIG. 1 shows an existing spectator seat 1 having an inclination in which the height rises stepwise on the upper surface (old floor surface 3) of the existing old floor portion 2 from the front to the rear. In this example, each step h between a plurality of sets of old floor surfaces 3 and 3 adjacent to the aisle direction and the width w of the old floor surface 3 of at least the rear three steps of the old floor portion 2 arranged adjacent to the aisle direction. Although an example is shown in the case where are equal, the width w of each step h and the old floor surface 3 is not always equal. The "passage direction" is the direction in which the old floor 2 is arranged.

FIG. 2 shows a state after the old seat 5 supported by each old floor portion 2 shown in FIG. 1 is rearranged into the new seat 7. When the old floor 2 is viewed in a continuous direction or a length direction (direction orthogonal to the aisle direction) as shown in FIG. 1, each old seat 5 is supported by each old floor 2 unit. In FIG. 1, an old seat 5 for spectators seated on the old floor 2 on the front side is supported (fixed) on the front surface (front side (front side) side surface) 4 of the old floor 2 (fixed). An example is shown in which the old seat 5 is fixed to the front surface 4 of the old floor 2 in the subsequent stage), but the old seat 5 is supported on the old floor 3 of the old floor 2 directly below it. In some cases.

In the drawing, the old seat 5 is arranged on each of the four adjacent old floors 2 (old floor surface 3), but among them, the adjacent three stages on the rear side (rear stage side) are arranged as described above. It is subject to replacement. In other words, in FIG. 2, of the four steps shown in FIG. 1, the adjacent three steps on the rear side are the units of one section, and are changed to the new floor portion 8 of the two steps shown in FIG. Of the four stages shown in (1), the old floor portion 2 in the front stage is changed in the same manner as the old floor portion 2 in the last stage. In the following, among the four steps shown in FIG. 1, the three steps on the rear side, which is the unit of one section, will be referred to as "adjacent three steps of the old floor portion 2". In FIG. 2, of the adjacent three-tiered old floors 2 that are in units of one section, the old seats 5 arranged on the middle-tier old floor 2 and the front-tier old floor 2 are removed, and the middle-tier old A new seat 7 is installed and fixed on the old floor surface 3 of the floor portion 2.

As shown in FIGS. 1 and 2, among the adjacent three-tiered old floors 2, on the old floors 3 and 3 of the two-tiered old floors 2 and 2 on the front side from which the old seats 5 and 5 have been removed. Tables 6 and 6 are newly installed and fixed. However, as described above, the sum of the widths w of the old floor 2 for the three steps is the sum of the widths W of the new floor 8 for the two steps (3w = 2W), so that the old floors of the adjacent three steps When the old floor 2 at the last stage of the 2 is changed to the new floor 8, the entire width of the old floor 3 is used as the new floor of the new floor 8 while being used as a part of the table 6. The width of a floor plate 62 described later can be used as a part of the new floor surface of the new floor portion 8. On the other hand, since the width of the floor plate 62 of the table 6 is the width of the new floor surface of the new floor portion 8 on the old floor portion 2 in the front stage, the old floor surface of each table 6 installed on each old floor surface 3 is used. The installation position in the width direction of 3 and the width of each floor plate 62 are different.

In addition, a new seat is newly placed on the front side of the table 6 on the old floor surface 3 on the rear side (middle stage of the three stages) of the old floor surfaces 3 and 3 of the old floor portions 2 and 2 on the front side. 7 is installed. The new seat 7 installed on the old floor surface 3 of the old floor portion 2 in the middle stage is sandwiched between the tables 6 and 6 in the aisle direction. This is because the space on the old floor surface 3 of the old floor portion 2 in the frontmost stage of the three stages is used as a passage for spectators to sit on the new seat 7 installed on the old floor surface 3 in the middle stage. As a result, the three-tiered old floor 2 is changed to the new two-tiered new floors 8 and 8 after the table 6 is installed, and a new spectator seat 9 is formed.

In FIG. 2, the old seat 5 for spectators who uses the old floor surface 3 of the old floor portion 2 at the last of the three steps as a passage is left, but it can be replaced with the new seat 7. For the old floor 2 on the front side of the table 6 installed on the old floor 2 on the frontmost stage of the three stages, the same procedure as on the old floor 2 on the last stage of the three stages is repeated. Therefore, the old seat 5 arranged on the old floor 2 is also left, but it may be replaced with the new seat 7.

In the example of the drawing, when the width w of the old floor surface 3 of the old floor portion 2 of at least three steps is 800 mm as shown in FIG. 1, the new floor portion of two steps having a width W of 1200 mm is shown in FIG. An example of changing to 8 is shown, but the widths of all the new floors 8 are not always the same.

The table 6 has a partition plate 61 that partitions the space between the new seat 7 and the old seat 5, which are adjacent to the front side in the aisle direction after the change (rearrangement), and the new seat 7, and the partition plate 61 on the rear side in the aisle direction. A floor plate 62 that is integrated and projects rearward in the aisle direction is provided, and in some cases, as shown in FIG. 1, a top plate 63 for placing a beverage or the like is fixed to the upper portion of the partition plate 61. The table 6 is made of steel, concrete, plastic, wood, or the like.

FIG. 2 shows an example in which the front surface of the partition plate 61 of the table 6 is aligned with the front surface 4 of the frontmost old floor 2 of the three adjacent old floors 2. ing. In this example, in particular, a table 6 with a floor plate 62 that can be used as a passage or the like is installed on the old floor 2 in the front of the three steps, and the old floors of the old floors 2 and 2 adjacent to each other in the front and rear of the passage direction. 3 is used as it is as the new floor portion 8.

For this reason, between the upper surface of the floor plate 62 located on the old floor 2 on which the table 6 is installed and the old floor 3 of the old floor 2 on the front side (the frontmost of the four steps). The level difference (step) H1 and the level difference (step) H2 between the upper surface of the floor plate 62 and its two steps, and the old floor surface 3 of the old floor portion 2 on the rear side (the last step of the four steps) The position (height) of the floor plate 62 of the table installed on the old floor portion 2 of the frontmost stage of the three stages is adjusted so as to be equal.

As described above, in FIG. 2 after the seat change, among the three adjacent new floors 8 as the new spectator seats 9, the old floor 3 forming the adjacent two new floors 8 and 8 on the front side The step H1 between the upper surface of the floor plate 62 and the upper surface of the floor plate 62 forming the two adjacent new floor portions 8 and 8 on the rear side and the step H2 between the old floor surface 3 are made equal. This means that the field of view of the spectators seated in the rear seats of the adjacent two-tiered new seats 7 and old seats 5 can be made constant. The field of view of a spectator seated in a relatively rear seat is actually determined by the step between the upper surfaces of the seats adjacent in the aisle direction.

The partition plate 61 is fixed to, for example, an old floor portion 2 located below the base plate (not shown) fixed to the lower end portion of the partition plate 61. The base plate is fixed to the old floor 2 using bolts, anchors, or a filler such as mortar or adhesive. When each part (plate portion) of the table 6 is plate-shaped, the rigidity of each plate 61 to 63 is required on the rear surface of the partition plate 61, the lower surface of the floor plate 62, and the lower surface of the top plate 63. A reinforcing material (reinforcing plate) 64 for securing is fixed.

The floor plate 62 basically has a width that only abuts or abuts on the front surface 4 of the old floor portion 2 on the rear side of the floor plate 62. If the gap between the floor plate 62 and the front surface of the old floor portion 2 on the rear side is large, there is a risk of pinching the legs. Legs and the like that reach the old floor 3 of the old floor 2 directly below are connected below the portion of the old floor 2 on the rear side of the floor plate 62 near the front surface 4, and the old floor 2 is connected via the legs. Supported by.

In FIG. 2, a new seat 7 for spectators using the front floor plate 62 as an aisle is installed on the middle old floor 2 of the adjacent three-tiered old floors 2, and the same middle tier old On the floor portion 2, a passage for spectators who uses the old floor portion 2 at the last stage as a passage or a table 6 having a floor plate 62 which can be used as a footrest is installed and fixed. The old seat 5 is fixed to the front of the old floor 2 in the rear stage of the old floor 2.
