DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectator seat in a stadium or a theater, and more particularly to a structure of a self-cleaning spectator seat in which floor cleaning is automated.

[0002]

2. Description of the Related Art As is well known, in a stadium such as a baseball stadium or a theater such as a movie theater, a large number of chairs are arranged vertically and horizontally to form a spectator seat. There are various types of chairs, and for example, there is a chair having a structure in which a seat portion is flipped up to a backrest side to easily clean a floor surface or the like. In general, this cleaning is manually performed by a cleaning worker holding a houki, a garbage bag, or the like.

[0003]

In such a conventional audience seat, the space between the chairs is so small that it is difficult to clean the chairs, and the number of chairs is large, so that the amount of work is large. For this reason, many workers take a long time. For this reason, cleaning is often performed intensively at midnight after the spectators return from the stadium or theater. Moreover, the work itself is not very hygienic, which has led to a chronic labor shortage of cleaning workers. In addition, this led to a rise in cleaning labor wages.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a self-cleaning spectator seat that can automatically perform cleaning with almost no need for a cleaning operator. It is in.

[0005]

In order to achieve the above-mentioned object, the present invention provides a seating system in which chairs are arranged vertically and horizontally.
A step-like stepping floor, a bottom floor provided below the stepping floor for dropping trash, at least a tilting means for tilting the stepping floor divided in every horizontal row to drop trash, and Receiving with the receiving sheet provided between the tread and the bottom floor,
Collecting means for collecting the trash by moving the receiving sheet.

The receiving sheet is supported by, for example, a vertical rope and a horizontal rope. This horizontal rope is fixed to the vertical rope.
The collecting means includes a moving device that receives the vertical rope and moves the rope together with the rope.

The moving device can be a drum provided at a front end and a rear end of a spectator seat. These drums wind the vertical rope, the horizontal rope and the receiving sheet.

Below the drum at the front end of the audience seat, for example, a belt conveyor can be provided. This belt conveyor conveys the garbage received and moved by the receiving sheet to the outside of the audience seats.

[0009] Preferably, a washing device for washing the receiving sheet is provided. This washing device can be provided on the lower surface of the drum at the front end of the audience seat.

[0010] The spectator seats may include not only lower floor seats but also upper floor seats, and the front end of the upper floor seats may protrude above the lower floor seats. In this case, the belt conveyor cannot be provided below the protruding upper floor seat front end drum. Instead, an opening / closing portion may be provided in a part of the bottom floor, and a chute sheet for introducing dust from the receiving sheet on the upper floor into the receiving sheet on the lower floor may be provided so as to be able to be wound up and unwound. .

[0011]

When cleaning, the tilting means is operated to tilt the tread, and the dirt slides along the tilted tread to drop to the bottom floor. The dropped garbage is collected by the collecting means. That is, the dropped dust is received by the receiving sheet, and moves as the receiving sheet moves. The receiving sheet is supported by a vertical rope and a horizontal rope, and by moving the vertical rope to which the horizontal rope is fixed, the moving force is transmitted to the receiving sheet without difficulty. When the drum of the moving device winds the vertical rope, the horizontal rope, and the receiving sheet, the receiving sheet can be easily inverted and the dust can be transferred to another transporting means (for example, a belt conveyor). The garbage from the inverted receiving sheet is conveyed to the outside of the audience seats by a belt conveyor, and can be temporarily stored in a garbage storage area or loaded on a garbage truck, for example.

By providing the cleaning device, even if the garbage received on the receiving sheet is raw garbage, it is possible to clean the receiving sheet so as not to emit a bad odor.
Further, by providing the cleaning device on the lower surface of the drum, easy cleaning can be performed with the receiving sheet supported by the drum.

When an upper floor seat is present in the spectator seat and projects above the lower floor seat, an opening and a chute seat are provided on the floor surface at the front end of the upper floor seat to provide an upper floor. Garbage from the seat receiving seat passes through the opening / closing part and is thrown into the receiving seat on the lower floor seat by the chute seat.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an overall vertical side view of a self-cleaning spectator seat of the present embodiment. Not only the first floor but also the second floor. FIG. 2 shows an enlarged view of the first floor seat portion. 2
FIG. 14 is an enlarged view of the floor seat portion. In these audience seats, chairs 1 are arranged vertically and horizontally. The whole is inclined so that the front becomes lower, and the tread (including the floor between the chairs) 3 that the spectator steps on is stepped. 2 and 4 (enlarged view of the portion A in FIG. 2) and FIG. 5 (B in FIG. 2).
As shown in the enlarged view of FIG. 1, a bottom floor 5 is provided below the tread floor 3, and the floor is doubled. The bottom floor 5 is for dropping dust on the tread 3 as described later.

As shown in FIG. 4, the tread 3 is divided into horizontal rows. It is conceivable that the divided tread 3 is further divided in the lateral direction, for example, every predetermined portion (about 8 to 12 seats). The material of the tread 3 is a steel plate.
The mortar is packed on the back so that the audience does not make noise when walking. Alternatively, a damping steel plate in which a resin is sandwiched can be used. The tread 3 is rotatable about a fulcrum 7 and is placed on a floor support 9. Since the fulcrum 7 is provided rearward with a slight eccentricity with respect to the center of gravity of the tread 3, it is possible to prevent the audience from becoming unstable when riding on the tread 3.

The floor receiving material 9 is fixed to the bottom floor 5, has a substantially rectangular cross section, and has a front channel steel 1 in front.
1 and a steel material 13 at the rear and a steel material 15 connecting them. The chair 1 is fixed to the front surface of the channel steel 11. The fixed portion of the chair 1 is located only on the vertical surface of the front surface of the channel steel 11 on the steeply upper side (FIG. 2) and has no portion in contact with the tread 3, but the lower side with a gentle slope (FIG. 4) also touches the tread 3. For this reason, the rotating tread 3
A notch corresponding to the fixed portion of the chair 1 is provided. The fulcrum 7 is provided on the steel material 13. Fulcrum 7
Is located immediately below the tread 3 on the lower side (FIG. 4), but is located below the tread 3 on the upper side (FIG. 5). In this way, the position of the fulcrum 7 is changed according to the magnitude of the inclination angle so that the dust does not get on the seating portion of the chair 1 when the tread 3 is rotated. However, if dust is already present on the seat portion of the chair 1 from the beginning, the cleaning operator drops the dust on the tread 3 with a houki or the like in advance.

One end of a coil spring 19 is attached to the rear end of the tread 3 via a bracket 17, and the other end is attached to a grip 21. The grip 21 is fixed to the rope 23. The ropes 23 are provided in the vertical direction of the audience seats and are moved in the vertical direction so that the treads 3 provided in a large number in the vertical direction can be simultaneously rotated.

The bracket 17 contacts the steel 13 when the tread 3 rotates, and serves as a stopper for preventing the tread 3 from rotating more than a predetermined angle, for example, 45 degrees. In order to make this contact more accurate, a projection may be provided on the bracket 17 to make contact with the steel 13.

By providing the coil spring 19, the linear movement of the rope 23 can be converted to the rotation of the tread 3 without difficulty, and the mounting position of the grip 21 can be somewhat flexibly accommodated. ing.

The grip 21 can be attached to an arbitrary position on the rope 23, and the attachment position can be adjusted in accordance with the change in the length of the rope 23 over time.

The rope 23 is used in common for a large number of treads 3 existing in the vertical direction of the entire audience seat (FIGS. 2 and 3). It is received by the lower roller 25 in some places, and is prevented from being bent by its own weight. Further, in this embodiment, since the inclination angle of the audience seat is different between the upper stage and the lower stage, the upper roller 27 is arranged at a position where the inclination angle changes, and the angle of the rope 23 is adjusted. Electric screw screws 29 and 31 are connected to the rear end and the front end of the rope 23, respectively, and move the rope 23 in the vertical direction to rotate the tread 3. The tread 3 rotates and tilts when the rope 23 is moved, and when the movement is returned to the original state, the tread 3 can return to a horizontal position due to its own weight. The rope 23 is formed by twisting the rope material, and there is a possibility that a slight elongation may occur due to a temporal change. In order to adjust the elongation, the turnbuckle 3 is provided at the center of the rope 23 in the front-rear direction.
3 are provided.

The fulcrum 7 for rotating the tread 3 as described above.
And the connecting portion 34 composed of the rope 23, the bracket 17, the coil spring 19, the grip 21 and the like constitute tilting means for tilting the tread floor 3.

In the present embodiment, the collecting means for collecting the dust falling on the bottom floor 5 as described above is the receiving sheet 35 moving along the bottom floor 5 (FIGS. 2, 3 and 3). 6 ~
(FIG. 13). That is, the bottom floor 5 is inclined forward substantially in accordance with the inclination of the audience seats (FIGS. 2 and 14). A pair of guide rails 39 are provided vertically on left and right end walls 37 (FIG. 9) of the bottom floor 5, respectively. The cross-sectional shape of the guide rail 39 is substantially U-shaped, and both ends of the U-shape are bent inward. Rollers 41 are provided in these guide rails 39. The roller 41 has two wheels 43 connected by a shaft 45 so as to fit within the above-described U-shape. The shaft 45 is provided with a connecting fitting 47, which protrudes outside from the opening having the U-shape. A hole 49 is formed in this protruding portion, and the receiving sheet 35 is provided.
A horizontal rope 51 for supporting is fixed. In this way, the horizontal rope 51 is stretched in the horizontal direction by the rollers 41 in the left and right guide rails 39. Many horizontal ropes 51 are installed along the guide rail 39. Each horizontal rope 51 is fixed to a vertical rope 53.
That is, the horizontal rope 51 and the vertical rope 53 are woven at right angles to each other (not shown) and are orthogonal to each other. Two vertical ropes 53 are provided along the guide rails 39, and each is an endless rope, and is wound around drums 55 and 57 described later.

A receiving sheet 35 is spread and fixed on the horizontal rope 51 and the vertical rope 53. The length of the receiving sheet 35 in the vertical direction may be half the length of the vertical rope 53 that is an endless rope. Similarly, the horizontal rope 5
1 is also fixed only in a half range of the vertical rope 53.

The moving device for moving the receiving sheet 35 includes drums 55 and 5 which are wound around the vertical rope 53 and rotate.
Seven. That is, the driving drum 57 is provided at the rear end of the audience seat.
Is placed, and the vertical rope 53 is wound several times. As a result, when the driving drum 57 rotates, one of the vertical ropes 53 is unwound and the other is wound by the frictional force of the winding. The drive drum 57 has only the vertical rope 53 wound thereon and the horizontal rope 5
1 and the receiving sheet 35 are not wound, so that each one of the vertical ropes 53 is provided independently.

On the other hand, an idler drum 55 is provided at the front end of the audience seat. The number of the idler drums 55 is one, and has a length covering the entire width of the receiving sheet 35. In addition, the central portion passes the bent horizontal rope 51 and the receiving sheet 35 in a wound state and makes a return movement, so that the diameter is larger than the diameters at both ends (FIG. 1).
3). Further, the bearing 59 of the idler drum 55
The spring 61 constantly presses the drive drum 57 in a direction away from the drive drum 57.

The upper roller 63 is disposed at a position where the inclination angle of the vertical rope 53 changes (FIGS. 2 and 14), and the angle of the vertical rope 53 is adjusted. A lower roller 65 is provided on the vertical rope 53 below the vertical rope 53 existing in the folded state so as to prevent the vertical rope 53 from being bent by its own weight and coming into contact with the bottom floor 5.

Below the idler drum 55, a belt conveyor 67 is arranged in the left-right direction of the audience seats. A skirt 69 is attached between the idler drum 55 and the belt conveyor 67 so as to prevent dust from scattering. The belt conveyor 67 continues to a garbage storage area, for example,
The garbage is finally transported from the garbage storage site to the garbage disposal site, for example, by a garbage truck.

On the lower surface of the idler drum 55, a cleaning device 71 is provided. The cleaning device 71 includes a water nozzle 73 that sprays water onto the receiving sheet 35 supported by the idler drum 55, a brush 75 that rubs against the receiving sheet 35 that is supported, and a gutter 77 that receives dirt-containing water. Consists of This gutter 77 is a belt conveyor 67.
It leads to another drainage channel.

The second-floor seats (FIG. 14) of the spectator seats also receive and move garbage by the receiving sheet 35 similarly to the first-floor seats (FIG. 2). However, 2 protruding above the first floor seats
The belt conveyor 67 (FIG. 2) cannot be provided at the front end of the floor seat. Such a space does not exist, and even if it is provided, it obstructs the view of the audience on the first floor. For this reason, an opening / closing portion 79 is provided on a part of the floor surface at the front end of the protruding second floor seat. That is, the bottom floor 5 below the idler drum 55 is opened and can be opened and closed by the slide shutter 81.

The opening / closing portion 79 is further provided with a chute sheet 83 for introducing dust. That is, an electric sheet winder 85 is provided before and after the opening / closing portion 79. The chute sheet 83 can be wound and unwound. The two left and right ends of the two chute sheets 83 can be connected to each other by a chuck. The two chute sheets 83 are formed into a bag shape by being combined. The length of the bag-shaped chute sheet 83 is 1 at the lower end.
It has a length that is inserted between the inclined floors 3 of the floor seat and reaches the receiving sheet 35 of the first floor.

In FIG. 14, the same parts as those in FIG. 2 are given the same numbers. In FIG. 14, 87 is a machine room, 89 is a doorway for spectators, 91 is a hopper, and 93 is the ceiling of the first floor seat.

The operation of this embodiment will be described below.
When performing cleaning, the electric screw screws 29, 31
To move the rope 23, and pull the tread 3 around the fulcrum 7 via the connecting portion 34. The dust slides along the inclined floor 3 due to this rotation, and falls toward the bottom floor 5 below. At this time, it is practical that a small number of workers forcibly drop the garbage that does not fall and is caught on the chair 1 or the like by a hawk or the like. Further, the order of rotation of the treads 3 may be performed for each tread 3 divided for each predetermined seat in the lateral direction of the audience seats. When the refuse 51 is sufficiently dropped in this way, the tread 3 is returned to a horizontal state. In this way, by putting a lid on the tread 3, so to speak, it is possible to prevent the dropped dust 51 from being missed.

Thereafter, the driving drum 57 is rotated, and the receiving sheet 35 is moved along the bottom floor 5 toward the front of the audience seat. As a result, the dust received on the receiving sheet 35 moves together with the receiving sheet 35. At this time, the receiving sheet 35 is supported by the horizontal ropes 51 and the vertical ropes 53, so that even if the driving drum 57 rotates, a large moving force is not applied to the receiving sheet 35 itself, and the receiving sheet 35 easily moves without being torn. Is performed. As this movement progresses, the receiving sheet 35 is sequentially moved from the front end to the horizontal rope 51 and the vertical rope 53.
At the same time, it is wound around the idler drum 55, turned over, and folded downward. At the time of this reversal, dust falls and moves onto the belt conveyor 67. Garbage that does not fall off by this inversion,
For example, garbage or dirty water adhering to the surface of the receiving sheet 35 is sprayed by the water nozzle 73 and falls on the gutter 77 by being rubbed by the brush 75. And it is discharged to the drain.

In this manner, the receiving sheet 35 is turned upside down from the front end to the rear end, and the dust is removed and washed. When the receiving sheet 35 is folded over the entire length, that is, completely turned over, the driving drum 57
The rotation of is stopped.

The trash that has moved onto the belt conveyor 67 is transported leftward or rightward of the audience seats, for example, temporarily stored in a garbage yard, loaded on a garbage truck or the like, and transported to a garbage disposal site.

When the spectator seat is wider than the front width as shown in FIG. 3 and is so-called fan-shaped, the left and right widths of the receiving sheet 35 are equal to the front width of the spectator seat. Fit to width. Therefore, the part 93 (FIG. 3) of the audience seat cannot be automatically cleaned by the apparatus of this embodiment. Therefore, the cleaning is manually performed by the cleaning operator.

Further, the cleaning of the second floor seat (FIG. 14) is performed before the receiving sheet 35 of the first floor seat is moved. That is, first, the chute sheet 8 is
3 is unwound and the right and left ends are joined by a chuck to form a bag.
Then, the lower end of the bag-like chute sheet 83 is
It is inserted from between the inclined steps 3 of the first floor seat and reaches the receiving seat 35 of the first floor seat. After that, the opening / closing portion 79 is opened by the sliding shutter 81.

The tilting of the tread 3, the movement of the receiving sheet 35, and the cleaning
1 and the like. As a result, when the moved receiving sheet 35 is inverted at the portion of the idler drum 55, the dust falls and is thrown into the receiving sheet 35 on the first floor through the opening / closing portion 79 and the chute sheet 83. Simultaneously with this insertion, the receiving sheet 35 on the first floor is moved. In this way, the dust on the second floor and the dust on the first floor are moved by the receiving sheet 35 on the first floor and conveyed by the conveyor 67.

When the cleaning of the second-floor seat is completed as described above, the chuck of the chute sheet 83 is released, and the chute sheet 83 is wound by the electric sheet winder 85. Then, the slide shutter 81 is closed.

According to the above embodiment, since everything from the dropping of the dust 51 to the transportation thereof can be performed automatically, the cleaning can be performed with almost no cleaning operator.
Further, since the operation of collecting the dust 51 can be performed in a state where the tread 3 is closed, the dust and the dust are not soared by the wind, which is sanitary.

In the above embodiment, the chair 1 is of a fixed type (FIGS. 1 and 2). In other embodiments, the chair 1 has a structure in which the seating portion is flipped up to the backrest side. There may be.

Further, in the above embodiment, the tread floor 3 is described as being divided into a single row at predetermined seat intervals. In other embodiments, for example, the plan shape of the audience seat is a perfect square. In such a case, it is not necessary to divide the seat every predetermined seat, and the seat may be completely continuous in the lateral direction.

In the above embodiment, the tilting means for tilting the tread 3 has been described as rotating the tread 3 around the fulcrum 7, but in other embodiments, the tilt mechanism is tilted by a link mechanism. It may be. Further, a rod may be provided instead of the rope 23 of the present embodiment.

In the above embodiment, the receiving sheet 35 is supported by the vertical ropes 53 and the horizontal ropes 51. However, if the receiving sheet 35 can have a sufficiently large strength, , Such ropes 51,5
3 is unnecessary. When the ropes 51 and 53 are not used, the driving drum 57 and the idler drum 55
A length over the entire width of the receiving sheet 35 is required. Furthermore,
It is desirable that the surface of the drive drum 57 be subjected to processing for further increasing the friction with the receiving sheet 35.

[0046]

As described above, according to the self-cleaning spectator seat of the present invention, dirt dropped on the lower floor by tilting the tread of the spectator seat is easily collected by the collecting means. As a result, it is not necessary for the cleaning worker to manually work in the spectator seat where the space between the chairs is narrow as in the related art, and the work can be performed hygienically in a short time. In addition, since the collecting means receives and moves the garbage on the sheet, it is possible to prevent garbage and the like from attaching to the bottom floor.

Further, by supporting the receiving sheet with the horizontal rope and the vertical rope, the force required for movement can be transmitted to the receiving sheet without difficulty, and damage such as tearing of the receiving sheet can be prevented.

Further, by washing the receiving sheet with a washing device, it is possible to eliminate the possibility that garbage and dirty water adhering to the receiving sheet will rot and emit a bad smell.

Further, by providing an opening / closing portion and a take-out / unwind chute sheet on the second floor seat, there is no need to provide a belt conveyor like the first floor seat. Can be prevented from obstructing the field of view.
