Description

The present invention is a spectator seat that changes the arrangement of the seats while newly installing a table between the seats adjacent to the aisle direction of the existing spectator seats with a slope that raises the floor surface from the front to the rear. seat change method.

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 with a slope that raises the floor height from the front to the back, the aisle direction A plurality of rows of seats adjacent to each other are rearranged to a smaller number of seats (see Patent Document 1). This is due to the inability to change the form of the frame itself to which the seat is fixed. The front refers to the side of the field facing the spectators, and the back refers to the opposite side.

In Patent Document 1, from the existing spectator seats in which the distance between the floor surfaces arranged with a step in the aisle direction and the distance between the adjacent seats are equal, the floor is arranged while maintaining the distance between the seats constant. The audience seats have been changed so that the distance between the seats is greater than the distance between the faces. In this example, the existing floor serves as a footrest for spectators when they sit on the newly installed seats. Since the space between the floors and the space between the floors are not the same, the floor may not be used as a footrest (Paragraph 0018).

In Patent Document 1, the distance between adjacent seats after the installation of new seats is increased from the distance between existing seats to ensure ample space between the new seats. Since there is no regularity in the intervals between the floor and the floor, it is difficult to install the tables regularly when trying to install a new table.

An additional seat can be put in and taken out between adjacent regular seats by switching the state of an aisle board in which the additional seat is integrated and supported rotatably around a horizontal axis between the seats adjacent in the aisle direction. There is also a method (see Patent Document 2).

Japanese Patent No. 5166301 (claim 1, claim 2, paragraphs 0013 to 0019, Fig. 1, Fig. 2) Japanese Patent Application Laid-Open No. 7-279457 (paragraphs 0012 to 0014, FIGS. 4 to 7)

However, Patent Document 2 does not change the existing inter-seat distance, and does not correspond to newly installing a table.

SUMMARY OF THE INVENTION In view of the above background, the present invention proposes a method for changing spectator seats that is capable of accommodating new installation of tables while changing the distance between existing seats.

The seat change method of the spectator seats according to claim 1 is provided in the existing spectator seats having a sloping step-like height on the upper surface of the existing old floor from the front to the rear, and is adjacent to the aisle direction. A seat change method for changing the arrangement of seats while newly installing a table on the old floor of at least three stages,
The table is installed on the upper surfaces of the two front-side old floor sections among the upper surfaces of the three-stage old floor sections adjacent to each other in the passage direction, and the two front-side old floor sections are installed. A new seat is newly installed on the front side of the table on the upper surface of the old floor on the rear side of the upper surface of the
It is a constituent requirement that at least three levels of the old floor section adjacent to each other in the passage direction are changed to two new levels of new floor sections after the table is installed .

"Front" refers to the field side or stage side facing the audience as described above, and "rear" refers to the opposite side. ``From the front to the rear, the upper surface of the old floor is inclined so that the height rises'' means that it goes up from the front to the back, and goes down from the other side. The “passage direction” is the direction in which the upper surface of the stepped old floor 2 is moved up and down. The upper surface of the old floor part 2 is the old floor surface 3 . The upper surface of the old floor section 2 is also referred to as an old floor surface 3 below. Spectator seats include spectator seats for outdoor or indoor stadiums, such as track and field stadiums, soccer fields, etc., and indoor theater spectator seats.

As shown in FIG. 1, the step h between the three adjacent old floor surfaces 3, 3 in the passage direction and the width w of the upper surface of the old floor portion 2 (the old floor surface 3) are basically equal, 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 part 2 . Hereinafter, the width of the upper surface of the old floor section 2 (old floor surface 3) is also referred to as the width of the old floor section 2. The “width of the upper surface of the old floor” is the depth of the old floor 3 in the passage direction.

"At least three levels of old floors 2 arranged in the aisle direction" are at least three levels of existing old floors 2 that are continuous in the direction of the aisle where new tables 6 are to be installed. This means that the floor section 2 is changed to a new two-stage new floor section 8 (new audience seats 9) after the table 6 is installed.

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

In the case where the width w of each of the successive three stages of the old floor section 2 is equal, the dimension 3w that is three times the width w of the old floor section 2 for one stage is equal to the new floor section 8 for two new stages. is 2W (3w=2W), and the width W of the new floor portion 8 for one stage 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 of the two new floor sections 8 is equal (W1=W2), the width W is 1.5 times the width w of the old floor section 2 (W=1.5w). When the width W of the new floor portion 8 for each step 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, since the width W of the new floor section 8 is greater than the width w of the old floor section 2, by using this width difference (W−w), the new spectator seats 9 are adjacent to each other after the change. A space for installing a table 6 is secured between the new seats 7, 7 of the two-stage new floor sections 8, 8. - 特許庁The "new seats 7 after being changed to the spectator seats 9" referred to here includes the old seats 5 that have not actually been changed to the new seats 7 as described above.

Therefore, when the table 6 is installed, the space between the legs of spectators seated on the new seat 7 or the old seat 5 that is used as a new seat without replacement and the table 6 may become narrow. Avoided. As a result, while changing the distance between the existing old seats 5, 5, the spectators are released from the feeling of blockage 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 ensured. be.

Since the total 3w of the widths w of the three stages of the old floor section 2 is the total 2W of the widths W of the two stages of the new floor section 8 (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 part 2 among the three old floor parts 2 arranged in the passage direction (claim 2) ), the step H1 between the upper surface of the floorboard 62 and the old floor surface 3 on the previous stage side, and the step H2 between the upper surface of the floorboard 62 and the old floor surface 3 on the subsequent stage side are the old seats before the seat change. It can also be 1.5 times the level difference h between the floor surfaces 3,3. In that case, H1=H2. This means that the field of view of spectators seated on the new seats 7 on the relatively rear side is less likely to be obstructed by the spectators seated on the new seats 7 on the front side, and the field of view downward is widened.

The table 6 is installed and fixed on the old floor surfaces 3, 3 of the front two old floor portions 2, 2 among the old floor surfaces 3 of the three old floor portions 2 adjacent in the passage direction. . As shown in FIG. 2, among the old floor surfaces 3 of the three adjacent old floor units 2, the table 6 (partition plate 61 described later) installed on the old floor surface 3 of the old floor unit 2 in the foremost stage is If the legs are aligned with the frontmost part of the old floor 3, the width of the old floor 3 of the frontmost old floor 2 can be effectively used as the new floor 8. - 特許庁

The three adjacent old floor sections 2 are changed to the new floor section 8 by, for example, installing (arranging) floorboards 62 described later on the frontmost old floor section 2 . For this reason, for spectators who use this new floor 8 as a passage (foot rest), the old floor 2 on the rear side (middle) of the old floor surface 3 of the old floor 2 on the front two levels is used. A new seat 7 is installed on the front side of the table 6 on the old floor surface 3. - 特許庁Among the old floor surfaces 3 of the three adjacent old floor portions 2, the old seats 5 installed on the last old floor surface 3 do not affect the installation of the newly installed table 6. It can be used as it is even after the change. However, the old seat 5 can be freely exchanged for a new new seat 7.

Among the old floor surfaces 3 of the three adjacent old floor units 2, the table 6 installed on the old floor surface 3 of the old floor unit 2 in the foremost row is for spectators seated on the newly installed new seats 7. It can also be used for the purpose of setting up a walkway or a footrest. For example, a partition plate 61 that partitions the space between the new seat 7 adjacent to the front side of the table 6 in the aisle direction or the existing old seat 5 is integrated with the rear side of the partition plate 61 in the aisle direction, and the rear side of the aisle direction is integrated. By providing the floorboard 62 projecting to the floor (claim 2), the floorboard 62 can be used as a new passage (floor surface) or as a footrest. “Integration” includes the case where the floor plate 62 is integrally formed with the partition plate 61 and the case where the floor plate 62 is integrated as a result of joining (fixing). "Existing old seat 5" refers to the old seat 5 used as the new seat 7 as described above.

In this case, the floorboard 62 can be used as a new passage (floor surface) if the floorboard 62 hits the front surface (side surface) 4 of the old floor section 2 on the rear side, or has a width to the extent that it hits (claim 3). be possible. The "width to the extent that it hits" means that even if the floorboard 62 does not hit the front surface 4 of the old floor section 2 and a gap is generated between the floorboard 62 and the old floor section 2, the gap is It means that it is large enough not to interfere with its use as a footrest. If there is a gap between the floorboard 62 and the old floor section 2, the floorboard 62 on the old floor section 2 side is supported by the old floor section 2 thereunder via a support member 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 seats 7 are installed is replaced with the old floor plate 62 of the old floor portion 2 adjacent to the rear side (last stage). If it is equal to the height of the floor surface 3, the floor plate 62 is connected to the old floor surface 3 of the old floor portion 2, the new upper surface (new floor surface) of the new floor portion 8 is formed flat, and the passage (footrest area) is formed. ) can be expanded.

In order to change at least three old floors adjacent in the aisle direction to two new floors after the table is installed, the difference between the width W of the new floor and the width w of the old floor (W - w ), it is possible to secure a space for installing a table between new seats on two adjacent new floors. Therefore, the space between the legs of the spectators seated on the new seats and the table will not be narrowed due to the installation of the tables. It is possible to be released from the closed feeling in the seat, and to secure a feeling of openness and security in the seated state.

FIG. 10 is a vertical cross-sectional view showing existing spectator seats in which the widths of upper surfaces of at least three old floor sections arranged adjacent to each other in the aisle direction are equal; It is a vertical cross-sectional view showing spectator seats after changing the old three-tiered floor section to a new two-tiered new floor section after the installation of tables.

FIG. 1 shows an existing spectator seat 1 in which the upper surface (old floor surface 3) of an existing old floor 2 is inclined so that the height rises stepwise from the front to the rear. In this example, each step h between a plurality of pairs of old floors 3 adjacent in the passage direction and the width w of the old floors 3 of at least three rear-side old floors 2 arranged adjacent in the passage direction are equal, but each step h and the width w of the old floor surface 3 are not necessarily equal. The “passage direction” is the direction in which the old floors 2 are arranged.

FIG. 2 shows the state after the old seats 5 supported by the old floors 2 shown in FIG. 1 are rearranged to new seats 7 . When the old floor section 2 is viewed in a continuous direction or a longitudinal direction (a direction orthogonal to the aisle direction) as shown in FIG. 1, each old seat 5 is supported by each old floor section 2 unit. In FIG. 1, old seats 5 for spectators seated on the front side of the old floor 2 are supported (fixed) on the front (front side (front side) side) 4 of the old floor 2 ( The old seat 5 is fixed to the front surface 4 of the old floor section 2 in the subsequent stage), but the old seat 5 is supported on the old floor surface 3 of the old floor section 2 immediately below it. Sometimes there are.

In the drawing, the old seats 5 are arranged on each of the old floors 2 (old floor surfaces 3) of the four adjacent tiers. subject to replacement. In other words, in FIG. 2, among the four stages shown in FIG. 2, the former floor section 2 in the foremost stage is changed in the same manner as the old floor section 2 in the last stage. In the following description, of the four stages shown in FIG. 1, the three stages on the rear side, which are units of one section, are referred to as "adjacent three-stage old floor section 2". In Fig. 2, among the three adjacent old floors 2 that form one section unit, the old seats 5 that were placed on the middle old floor 2 and the former floor 2 were removed, and the old seats 5 in the middle A new seat 7 is installed and fixed on the old floor surface 3 of the floor part 2. - 特許庁

As shown in FIGS. 1 and 2, among the three adjacent old floors 2, on the old floor surfaces 3, 3 of the front two old floors 2, 2 from which the old seats 5, 5 have been removed Tables 6, 6 are newly installed and fixed. However, since the sum of the widths w of the three stages of the old floor portions 2 is the sum of the widths W of the two stages of the new floor portions 8 as described above (3w=2W), the adjacent three stages of the old floors In the last stage of the old floor 2 of the section 2, when it is changed to the new floor 8, while using the full width of the old floor 3 as the new floor of the new floor 8, a part of the table 6 The width of a certain later-described floor board 62 can be used as part of the new floor surface of the new floor section 8 . On the other hand, since the width of the floor board 62 of the table 6 on the frontmost old floor section 2 is the width of the new floor surface of the new floor section 8, the old floor surface of each table 6 installed on each old floor surface 3 is 3 and the width of each floor plate 62 are different.

In addition, among the old floors 3, 3 of the old floors 2, 2 on the front side, a new seat is newly installed on the front side of the table 6 on the old floor 3 on the rear side (middle of the three tiers). 7 is installed. A new seat 7 installed on the old floor surface 3 of the old floor part 2 in the middle is sandwiched between the tables 6, 6 in the aisle direction. This is because the space on the old floor surface 3 of the old floor part 2 of the frontmost stage among the three stages is used as a passageway for spectators who sit on the new seats 7 installed on the old floor surface 3 of the middle stage. As a result, the three-tiered old floor section 2 is changed to new two-tiered new floor sections 8, 8 after the table 6 is installed, and new spectator seats 9 are formed.

In FIG. 2, the old seats 5 for spectators using the old floor surface 3 of the last floor 2 of the three stages as passageways are left, but they can be replaced with new seats 7. For the old floor section 2 on the front side of the table 6 placed on the old floor section 2 in the foremost stage among the three stages, the same operation as for the old floor section 2 in the last stage among the three stages is repeated. Therefore, although the old seat 5 arranged on the old floor 2 is also left, it may be replaced with a new seat 7. - 特許庁

In the example of the drawing, when the width w of the old floor surface 3 of the old floor section 2 of at least three stages is 800 mm as shown in FIG. Although an example of changing to 8 is shown, the width of all the new floor sections 8 is not necessarily the same.

The table 6 has a partition plate 61 that separates the space between the new seat 7 and the old seat 5 adjacent to each other on the front side in the aisle direction after the change (rearrangement), or between the new seat 7, and the rear side of the partition plate 61 in the aisle direction. A floor plate 62 is integrally formed and protrudes rearward in the passage direction. Optionally, as shown in FIG. The table 6 is made of steel, concrete, plastic, wood, or the like.

FIG. 2 shows an example in which the surfaces of the partition plates 61 of the tables 6 on the front side, which are the surfaces of the partition plates 61 of the tables 6, are aligned with the front surface 4 of the front surface 4 of the old floor section 2 of the foremost stage among the three adjacent old floor sections 2. ing. In this example, a table 6 with a floorboard 62 that can be used as a passage or the like is installed on the frontmost old floor 2 of the three stages, and the old floors 2, 2 adjacent to each other in the passage direction are installed. 3 is used as a new floor 8 as it is.

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

In this way, in FIG. 2 after the seat change, among the three new floors 8 adjacent as new spectator seats 9, the old floor 3 forming the two new floors 8, 8 adjacent on the front side and the above A level difference H1 between the upper surface of the floor board 62 and a level difference H2 between the upper surface of the floor board 62 and the old floor surface 3 forming two new floor portions 8, 8 adjacent on the rear side are made equal. This has the meaning of making the field of view of spectators sitting on the relatively rear seat of the two adjacent new seats 7 and old seats 5 uniform. The field of vision of spectators seated on relatively rear seats is actually determined by the difference in level between the upper surfaces of the seats adjacent to each other in the aisle direction.

The partition plate 61 is fixed to the old floor portion 2 positioned thereunder by a base plate or the like (not shown) fixed to the lower end of the partition plate 61, for example. The base plate is fixed to the old floor 2 by means of bolts, anchors or, in addition, fillers such as mortar and adhesive. When each part (plate part) of the table 6 is plate-shaped, the rigidity of each of the plates 61 to 63 is applied to the back surface of the partition plate 61, the lower surface of the floor plate 62, and the lower surface of the top plate 63 as necessary. A reinforcing member (reinforcing plate) 64 is fixed for securing.

The floor board 62 basically has a width that is enough to hit the front surface 4 of the old floor part 2 on the rear side of the floor board 62, or to the extent that it hits. This is because if the gap between the floor plate 62 and the front surface of the old floor section 2 on the rear side is large, there is a risk of pinching the foot. Below the portion near the front surface 4 of the old floor 2 on the rear side of the floor plate 62, the leg or the like that reaches the old floor surface 3 of the old floor 2 directly below is connected, and the old floor 2 is connected via the leg. supported by

In FIG. 2, among the three adjacent old floors 2, new seats 7 for spectators are installed on the middle old floor 2 using the frontmost floor board 62 as a passage, and the same middle old old floor 7 is installed. On the floor part 2, a table 6 having a floor plate 62 which can be used as a passage for spectators using the last floor part 2 as a passage or as a footrest is installed and fixed. The old seat 5 is fixed to the front surface of the old floor part 2 in the rear stage of the old floor part 2. - 特許庁
