  Patent Literature 1 below discloses a turf growing device in which a reflector is provided at a front end of a roof eave and a natural light is irradiated on grass on a field surface. This turf growing device is provided with a mechanism such as a bracket for attaching a reflector and a gear for moving the bracket.

JP-A-8-277644

  When the turf growing device disclosed in Patent Document 1 is used for growing turf on a field surface, a large number of turf growing devices must be installed to irradiate a wide area. For this reason, there are problems such as difficulty in securing an installation place, a large number of installation steps, and an increase in manufacturing cost of the apparatus.

  The present invention has been made in consideration of the above facts, and has as its object to effectively utilize sunlight by using a normally provided spectator seat without providing a dedicated facility for using the sunlight in a stadium or the like. I do.

The seat according to claim 1 is provided with a movable seat provided in an insolation-enabled area, and is provided so as to be fixed at an arbitrary position on a side opposite to a seating surface of the seat, and is configured to direct sunlight to a grass surface of a field. And a convex reflector that reflects light .

  According to the seat of the first aspect, when the seat is moved when the seat is not used, the solar light can be applied to the functional member provided on the opposite side of the seating surface of the seat. When the sunlight shines on the functional member, the functional member exhibits a function using the sunlight.

  For example, when the functional member is a solar panel, it converts light into electric energy and generates power when the seat is not in use. Further, for example, when the functional member is a reflector, the lawn is grown by reflecting the sunlight reflected by the reflector on the grass surface of the field.

  As described above, the sunshine can be effectively used by using the seats of the spectator seats usually provided in a stadium or the like without providing a dedicated facility for using the sunshine.

Further, the functional member is a convex reflector that reflects the solar light to the grass surface of the field.

The functionality member by a convex reflector, the reflected light is widely lawn surface is irradiated is diffused.
According to a second aspect of the present invention, in the seat according to the first aspect, the convex reflector is provided on an attachment that can be fixed at an arbitrary position on a side of the seat portion opposite to the seating surface.

The seat according to claim 3 is the seat according to claim 2 , wherein the attachment is detachable from the seat.

  According to the seat according to the third aspect, a functional member having a different function can be replaced as needed. For example, a wide-area lawn surface is usually illuminated by diffused light using a convex reflector, and if there is a place where the turf growing condition is poor, the reflected light is radiated to a pinpoint without being diffused by replacing it with a flat reflector. This makes it possible to flexibly respond to the growing condition of the turf.

  As described above, according to the seat of the present invention, it is not necessary to provide a dedicated facility for using the solar light in a stadium or the like, but to effectively use the solar light by using a normally provided spectator seat. Can be.

[First Embodiment]
Hereinafter, the seat 20 according to the first embodiment of the present invention will be described with reference to the drawings.

(Stadium)
As shown in FIG. 1, the seat 20 is a fixed chair installed on a spectator seat portion of the stadium 10, that is, on the corrugated floor 12.

  The stadium 10 in the first embodiment is a large-scale stadium facility used at the time of a big event such as the Olympics. In the first embodiment, a case in which the seat 20 is applied to the stadium 10 will be described. However, the seat 20 is not limited to the stadium 10 but may be any place where sunlight can be received (insolation-enabled area). It can be applied to various places both indoors and outdoors.

  The stadium 10 includes a field 16 having a lawn surface on which turf 14 is planted, a step floor 12 surrounding the field 16, and a roof 18 covering an upper part of the step floor 12.

  The turf 14 is a plant that needs light for growing (so-called natural turf), but a part of the field 16 may include a place using artificial turf.

  The corrugated floor 12 is a structure formed in a mortar shape so as to surround the field 16, and a seat 20 is installed on the corrugated floor 12 to form a stair-shaped audience seat.

  An opening 18A is formed at the center of the roof 18, and sunlight enters the stadium 10 through the opening 18A. Note that the “opening” is a concept that includes all components through which light can pass, and may be covered with a light-transmitting film material or the like as long as it allows solar radiation to pass through the inside of the stadium 10, for example. .

(seat)
As shown in FIG. 2B, a plurality of seats 20 are arranged on the corrugated floor 12 in a row along the field 16. In addition, as shown in FIG. 2A, the seats 20 are arranged for each step of the corrugated floor 12.

  The seat 20 includes a seat 22, a back 24, a pair of legs 26, an attachment 28, and a base frame 30.

  The base frame 30 is a strength member bent in a crank shape, and a shaft portion 32 protruding toward the seat portion 22 is provided in the bent portion. The shaft portion 32 supports a side surface in the width direction of the rectangular seat portion 22, and the seat portion 22 located between the base frames 30 is rotatable up and down around the shaft portion 32. I have.

  From the lower part of the base frame 30, the leg 26 extends downward. The legs 26 are fixed to the floor 12 with bolts (not shown).

  Further, a back portion 24 is attached to an upper portion of the base frame 30. The back part 24 is curved up and down in a convex shape according to the shape of the back of the spectator sitting on the seat part 22.

Further, as shown in FIG. 2C, a shaft hole 28B formed in a flange 28A protruding outward from an end of the panel-shaped attachment 28 is formed in the shaft portion 32 of the base frame 30. I agree. The attachment 28 is provided on the opposite side of the seat 22 from the seating surface 22A. When the attachment 28 is hung down from the shaft portion 32, the attachment 28 is located behind the leg 26 by the length of the flange 28A. This prevents the attachment 28 from hitting the seated audience even if the foot is bent under the seat 22.
A depression 28C is formed on the surface of the attachment 28, and a reflector 40 as an example of a functional member is fitted into the depression 28C.

  In addition, the base frames 30 of the adjacent seats 20 are fixed by the connecting members 34 to reinforce the seats 20 arranged in a row, but the embodiment of the present invention is not limited to this. For example, the connecting member may be formed in a skewered shape so as to penetrate through the base frames 30 of the plurality of seats 20 arranged in a row. At this time, by extending the legs for fixing to the floor 12 from the connecting member, the legs 26 provided for each seat 20 can be omitted. In this case, the attachment 28 is positioned on the field 16 side of the connecting member so that the reflection plate 40 does not interfere with the connecting member.

(reflector)
As an example of a functional member, a reflection plate 40 that can reflect sunlight is fitted into the depression 28 </ b> C formed on the surface of the attachment 28. The reflection plate 40 is a stainless plate whose reflection surface 40A is curved in a convex shape, and the reflection surface 40A is mirror-finished. In this embodiment, polishing is performed as mirror finishing, but cold rolling, bright heat treatment, plating, or the like may be performed. The material of the reflection plate 40 is not only stainless steel, but also various metal plates such as aluminum and copper plates, a mirror in which metal is vapor-deposited on a glass surface, and a high-reflectivity sheet material adhered to a wooden base. Etc. can be applied as appropriate.

  It is not necessary to use all the seats of the stadium 10 as the seats 20 provided with the reflector 40 and the attachment 28. You may. Further, the attachment 28 may be configured to be detachable from the seat 20.

(Bounce mechanism)
As shown in FIG. 5, a flip-up mechanism 50 is provided at a connection portion between the shaft portion 32 of the base frame 30 and the seat portion 22. In order to dispose the flip-up mechanism 50, a corner of the seat 22 is cut out, and a shaft hole 22D is formed in the cutout surface 22C. A box 23 having a through hole 23A having an axis coinciding with the axis hole 22D is formed on the bottom surface of the notch surface 22C.

  The small shaft portion 32A formed at the tip of the shaft portion 32 protruding from the base frame 30 is inserted into the through hole 23A and the shaft hole 22D. As a result, the seat portion 22 can be turned vertically with respect to the shaft portion 32.

  Further, a torsion spring 54 is externally inserted into the small shaft portion 32A. One end 54A of the torsion spring 54 is locked by a locking portion 23B formed on the bottom surface of the box 23, and the other end 54B is locked by a locking portion 32B formed on the end surface of the shaft portion 32. ing. When the seat portion 22, the box 23, the torsion spring 54, and the shaft portion 32 are assembled, the torsion spring 54 is surrounded by the box 23 and cannot be visually recognized.

  As a result, when the seat portion 22 is tilted to the seating position, a spring force is accumulated in the torsion spring 54 in the clockwise direction M shown in FIG. Therefore, when the spectator separates from the seat 22, the seat 22 is jumped up to the upright position by the spring force of the torsion spring 54.

  That is, the seat 20 needs to be manually tilted by the flip-up mechanism 50 when seated, but when the seat 20 is released, the seat 22 is moved to the upright position by the spring force of the torsion spring 54. Since it returns, there is no need to return manually.

  In the present embodiment, the torsion spring 54 is used as the flip-up mechanism 50. However, a mechanism for flipping the seat 22 using an oil damper, a gas damper, or the like may be used. Further, a configuration may be adopted in which the seat portion 22 is manually moved when the seat portion 22 is at any of the standing position and the sitting position without providing the flip-up mechanism itself.

(When using seats)
FIG. 2 shows a state in which the seat 22 is tilted down, for example, when a spectator sits down while the stadium 10 is being used, and the seating position is held. At this time, the attachment 28 is hung down, and the reflection surface 40A of the reflection plate 40 is facing the opposite side of the field 16 (the riser portion 12A side of the floor 12).

(When seat is not used)
FIG. 3 shows an empty seat 20 when the stadium 10 is in use. The seat 22 is in the upright position by the spring force of the torsion spring 54 described above, and the attachment 28 has the reflecting surface 40A of the reflecting plate 40 facing the opposite side of the field 16 as in the case of using the seat 20. ing.

(When using a reflector)
FIG. 4 shows a state in which the reflector 40 is used while the stadium 10 is not in use. The hanging attachment 28 is pulled up between the legs 26 and is brought into contact with the back surface of the seat 22. On the back surface 22B of the seat portion 22, a concave portion 22C in which a corner of the attachment 28 is accommodated is formed. Thereby, the reflection surface 40A of the reflection plate 40 faces the field 16 side. The attachment 28 is not provided with the flip-up mechanism 50 and must be manually moved. However, at a position where the reflection surface 40A of the reflection plate 40 faces the field 16 side, the reflection plate 40 falls down on the back surface 22B of the seat portion 22, and the It becomes independent by the frictional force between the hole 28B and the shaft portion 32.

  In the present embodiment, the attachment 28 is self-supported by the frictional force with the shaft portion 32, but the embodiment of the present invention is not limited to this. For example, the friction with the shaft portion 32 may be reduced, and a magnet, a latch mechanism, or the like may be provided between the attachment 28 and the back surface 22B of the seat portion 22 as fixing means. At this time, in order to prevent the attachment 28 from suddenly moving due to its own weight, the torque may be adjusted by using a rotary damper or the like for the shaft portion 32.

  Also, the attachment 28 is manually moved, but embodiments of the present invention are not limited to this. For example, it may be moved by a driving device such as a motor using an electric signal. By doing so, it is possible to reduce the labor for manually flipping the seat 22 up.

(Action and effect)
According to the seat 20 of the first embodiment, as shown in FIG. 4, when receiving the solar light with the reflecting surface 40A facing the field 16, the reflecting surface 40A reflects the solar light. Note that the solar light in the present invention is a concept including both direct solar light and scattered solar light, and the reflecting plate 40 has a reflecting surface 40A that is curved in a convex shape. In addition, the direct sunlight that is parallel light is diffused and reflected (angle R1). In addition, non-directional scattered solar light is also diffused and reflected (angle R2). The angle R1 is an angle between the traveling directions of the respective reflected lights reflected from both ends of the reflection plate 40. Further, the angle R2 is an angle formed by each tangent of both ends of the reflection plate 40.

That is, since the solar light is reflected by the reflection plate 40, the field 16 can be irradiated with the reflected light as shown by the broken line in FIG. Further, since the reflected light becomes diffused light, it is possible to irradiate a wide surface of the field 16. Therefore, the growth of the turf 14 is promoted. In addition, reflected light can be applied to all-day shade areas where direct sunlight does not reach throughout the day, and permanent shade areas where direct sunlight does not reach throughout the year. Can be nurtured. Therefore, the necessity of irradiating artificial light with electricity for turf growing is reduced, and the environmental load can be reduced.
This effect is particularly remarkable in winter, when the mid-south altitude is low and sunlight is blocked by the roof 18 and the field 16 cannot be irradiated for a long time.

  Further, according to the seat 20 of the first embodiment, the seat portion 22 and the attachment 28 are separate members, and the reflecting plate 40 does not face the field 16 except when used, regardless of whether the seat is occupied or vacant. In addition, it is possible to prevent a player during the competition or a spectator on the opposing surface from feeling the glare even if the user visually recognizes the seat 20.

  Also, the stadium 10 is provided with a corrugated floor 12, and the seats 20 are arranged in a row in each row of the corrugated floor 12, so that the reflecting plate 40 can easily receive the solar light and the reflected light can be reflected. Easy to pass. That is, compared with the case where the seats 20 are arranged in a plurality of rows in a flat place, the sunlight and the reflected light are less likely to be blocked by the back 24 of the seats 20 in the front row.

  In addition, by using the seat 20 of the first embodiment, the solar light can be used without providing a dedicated facility for reflecting the solar light, thereby saving space and reducing capital investment.

[Second embodiment]
Hereinafter, the seat 60 according to the second embodiment of the present invention will be described with reference to FIG. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and description thereof will not be repeated.

(seat)
As shown in FIG. 6, the seat 60 of the second embodiment does not include the attachment 28 of the first embodiment, and has a reflection surface 80 formed on the back surface of the seat portion 62.
The configurations of the back portion 64, the leg portion 66, the base frame 70, and the shaft portion 72 are the same as the back portion 24, the leg portion 26, the base frame 30, and the shaft portion 32 of the first embodiment, respectively.

(Seat)
The back surface 62 </ b> B of the seat 62 is formed to be curved in a convex shape, and is coated with a paint to form the reflection surface 80. The paint is a high-reflection paint having a higher reflectance of sunlight than that of a general paint having the same brightness, but has a lower reflectance than the reflector 40 of the first embodiment. In the present embodiment, a high-reflection paint is used as a paint, but this may be a general paint having high brightness (for example, white). Alternatively, the reflectance of the solar light may be increased by, for example, changing the color of the resin forming the seat portion 62 to a high-brightness color, or kneading powder such as aluminum flake into the resin. Thus, in the second embodiment, the back surface of the seat itself can be used as the reflection surface.

  Note that the seat 60 includes the flip-up mechanism 50 as in the seat 20 of the first embodiment, but this may be omitted and a structure in which the seat portion 60 is manually raised and lowered may be adopted.

(Action and effect)
According to the seat 60 of the second embodiment, as compared with the seat 20 of the first embodiment, since the attachment 28 is not provided, manufacturing is easy. Further, when the seat 62 is in the upright position, the field 16 is irradiated with solar light, so that the labor for manually operating the attachment 28 is reduced.

  In addition, since the high-reflection paint of the second embodiment has a lower reflectance than the reflection plate 40 of the first embodiment, the athlete in the competition or the spectator on the opposing surface may feel the glare even when viewed visually. Is suppressed.

  In addition, for example, by using a luminous paint as the paint, it is possible to cause the luminous energy to be stored by daylight and to be emitted at nighttime events. In this way, it is possible to function as a foot light that does not use electric power.

[Modification]
Next, a modification of the above embodiment will be described.

  In the first embodiment, the reflection plate 40 is arranged so that the reflection surface 40A is curved in a convex shape, but the embodiment of the present invention is not limited to this. For example, the reflection plate may be embossed by press molding so that the reflection plate itself has irregularities so that the solar light is irregularly reflected. Even in this case, the reflected light is diffused, and the strength of the reflector can be increased.

  In addition, the reflection plate 40 may be, for example, curved in a convex shape or may be a smooth flat plate that is not embossed. With this configuration, the diffusion of the reflected light is suppressed, so that the area irradiated with the reflected light can be reduced, and the illuminance of the portion irradiated with the reflected light can be increased. Thereby, the turf 14 of a specific portion can be intensively grown.

  Further, the stadium 10 may be used in combination with the seat 20 provided with the convexly curved reflector 40 and the seat provided with the flat reflector. In this way, it is possible to correct a state in which the growth of the turf 14 is uneven.

Further, in the first embodiment, the attachment 28 is fixed to the back surface of the seat portion 22, but the embodiment of the present invention is not limited to this. For example, the shaft 32 may be fixed at any position by using a ratchet mechanism. By fixing the attachment 28 at an arbitrary position, it is possible to adjust the direction of the reflected light according to the sun altitude or the sun's trajectory that varies from season to season.

  In the first and second embodiments, the turf 14 of the field 16 is illuminated by the light reflected by the reflection surface 40A and the reflection surface 80. However, the embodiment of the present invention is not limited to this. For example, the light reflected by the reflection surface 40A and the reflection surface 80 may be further reflected on the inside of the roof 18, that is, on the ceiling surface (secondary reflection), and the grass 14 may be irradiated with the secondary reflection light. . By using the secondary reflected light, the solar radiation utilization efficiency can be further increased.

  Although the functional member in the first embodiment is the reflection plate 40, the embodiment of the present invention is not limited to this. For example, a solar panel may be used. In this case, a solar panel is attached to the attachment 28, and the solar panel is electrically connected to the storage capacitor, the brightness sensor, and the LED lighting, so that the solar panel can function as a nightlight (foot light) at night. As described above, when the functional member is a solar panel, it is particularly effective as an electric power assist in the stadium 10 and the like which is a wide-area evacuation facility in the event of a disaster. Note that the solar panel can be applied to the second embodiment if it is attached to the back surface 62B of the seat 62 in the second embodiment.

  In addition, by using a heater instead of the LED lighting for the device connected to the solar panel, the feet can be warmed in winter. Alternatively, a similar effect can be obtained by directly absorbing, storing, and radiating solar heat by using the functional member as a heat storage unit instead of a solar panel.

  In the first embodiment, the attachment 28 may be configured to be detachable from the seat 20. In this case, instead of the reflecting plate 40, the embossed reflecting plate described above, It can be replaced with an attachment with a reflector and a solar panel. Alternatively, instead of making the attachment 28 detachable from the seat 20, the reflecting plate 40 may be made detachable from the attachment 28. In this manner, various functions can be given to the seat 20 as needed.

  As described above, the present invention may be appropriately combined with the above-described embodiment and various modifications, and may be embodied in various modes without departing from the gist of the present invention.
