[0001] The present invention relates to a sports stadium of the type that has a plurality
of turf modules which are assembled into a complete sports field with a turf surface.
In particular the invention regards solutions for providing good quality natural turf
on such turf modules.
Background
[0002] International patent application publication WO2013002649 describes a sports stadium
of the type discussed herein. Namely of the type having a plurality of turf modules
which can be assembled on a fixed support base into a complete sports field. When
not in use, the turf modules can be stored in a storage room below the fixed support
base. When in such a storing position, the operator can cultivate the turf by providing
light and water to the turf, while protecting the turf for harsh weather.
[0003] Although the storage room disclosed in
WO2013002649 can be suited for providing suitable climate for the natural turf, conventional methods
are still used for cultivating the turf. This includes the use of conventional watering
techniques and repeated inspection of the turf quality.
[0004] Various movable turf fields made up of turf modules are also described in
Turfgrass Bulletin, issue 214 of October 2001. This article describes how an entire turf field is assembled by a plurality of adjacently
arranged turf modules, having natural turf.
[0005] In the prior art, solutions are described regarding heating a natural turf. For instance,
Norwegian patent publication
NO304415 describes a sports field having natural turf. The field is provided with air-conducting
channels in a layer below the turf which is adapted for warming the turf. Cooled (used)
air returns through return channels below the turf.
[0006] Patent application
GB2395135 describes an artificial sports surface where an artificial turf is rolled out onto
a supporting surface from rolls. Between the supporting surface and the artificial
turf are also intermediate layers rolled out from rolls. The supporting surface is
built up by a plurality of supporting sub layers in the form of adjacently arranged
blocks, having an upper and lower plate, between which supporting webs are arranged.
The plates and webs form horizontally extending channels. These channels allows for
drainage of water which will penetrate the artificial turf and other layers above
them. The channels are also used for retro-fitting of piping through a plurality of
adjacently arranged blocks. Such piping can be used for feeding sprinkler heads with
water or other purposes, such as heating. This solution avoids extensive ground construction,
as the piping is retro-fitted into the blocks themselves and not in the supporting
ground.
[0007] JPH10313676 is discloses a solution having a piping in the ground below a turf. The
turf is divided into zones and the piping is sectioned for every zone. The amount
and temperature of heat medium flowing in the piping can be controlled to control
growth of the lawn. Moreover, temperature detectors are arranged in the ground for
the respective zones and to perform control based on the measured temperatures.
[0008] It is an object of the present invention to provide an improved solution for cultivating
the turf on turf modules of the above described type. Additional objects will appear
from the following description.
The invention
[0009] According to a first aspect of the present invention, there is provided a sports
stadium with a turf field and a surrounding spectators stand. The turf field is made
up of a plurality of turf modules supported on a fixed support base. The upper face
of the turf modules is turf. The turf modules are movable on the fixed support base,
and movable between an application mode on the fixed support base and a storage mode
in a storage location. According to the first aspect of the present invention, the
turf modules comprise integrated module resource lines that distribute resources to
the turf. Moreover, the turf modules comprise a module resource connection adapted
to connect to a fixed resource connection.
[0010] The invention will exhibit most advantages when the turf on the turf modules is natural
turf. However, the use of artificial turf on the turf modules is also within the scope
of the invention.
[0011] The module resource lines being integrated shall mean that these lines are fixed
parts of the turf modules. That is, they are not retro-fitted after the modules have
been installed in an application mode or in a storage mode. On the contrary, they
are part of the turf modules and are thus moved together with the turf modules.
[0012] In many preferred embodiments, the storage location will be an enclosed chamber having
either artificial lighting or natural lighting, such as in a greenhouse. By storing
the turf modules inside, i.e. in a chamber, the user is able to control the environment
in which the modules and the turf are stored.
[0013] Preferably, the fixed support base comprises fixed resource lines which connect to
fixed resource connections distributed on the fixed support base. In this manner,
every turf module is able to connect to a dedicated fixed resource connection.
[0014] The turf modules may in one embodiment be interchangeable between an elevated transport
condition, wherein wheels support the turf module, and a lowered resting condition,
wherein the module resource connection is adapted to connect with the fixed resource
connection as a result of the turf module being lowered from the transport condition
into the resting condition.
[0015] In an alternative embodiment, fixed resource connections are arranged at a perimeter
of the fixed support base and the module resource connections of some turf modules
connect to such at the perimeter arranged fixed resource connections when in the application
mode. In this alternative embodiment, some turf modules may transmit resources from
one adjacently arranged turf module to another adjacently arranged turf module.
[0016] In some embodiments, the storage localization is provided with fixed resource connections
and fixed resource lines, wherein the turf modules are connected with such fixed resource
connections when in the storage mode. Thus, the operator may supply resources to the
turf both when the turf modules are in the application mode (on the field / fixed
support base) and in the storage mode (storage location).
[0017] The resources supplied through the fixed resource lines comprise at least one of
the resources listed in the following group: water, temperated water, gas, temperated
gas, plant nutrition, electric power, sensor signaling.
[0018] Sensor signaling involves communication of sensed parameters, such as temperature
in the turf, to a parameter reader, normally a computer system. The supply of temperated
water and temperated gas shall be construed as the supply of water and/or gas, the
temperature of which is affected by the user. A typical example is the supply of hot
water or hot gas on a cold winter day to keep the turf sufficiently warm. Temperated
fluid can also be used in order to obtain optimal growth environment.
[0019] The storage localization can advantageously comprise a plurality of storage shelves
at different vertical positions, in which turf modules are arranged when in the storage
mode. The storage shelves are then provided with fixed resource lines in communication
with fixed resource connections in the storage shelves. The storage location, such
as a storage chamber, can be inside the sports stadium itself, such as below the fixed
support base. It may however also be outside the sports stadium.
[0020] Preferably, a plurality of the turf modules can be provided with an identification
code which is readable by a computer system, wherein also the position of an identified
turf module is readable by the computer system when in an application mode. Advantageously
the reading of the identification mode can be readable when the module resource connection
is in engagement with the fixed resource connection. E.g. RFID transponders connected
to the computer system and distributed in the fixed support base, and in the storage
localization may be applied.
[0021] The turf modules can comprise turf condition sensors that are readable by a computer
system. The sensed parameters may e.g. be communicated by wireless link or through
the engagement of the fixed resource connection with the module resource connection.
The turf condition sensors can typically be one or more of temperature sensors, humidity
sensors, decay gas sensors, and more.
[0022] Advantageously, resource valves are arranged in association with the fixed resource
lines and/or in association with the module resource lines. Such resource valves can
advantageously be remotely operable. Such an embodiment makes the operator able to
adapt the supply of resources, typically water or heat, to the turf modules in need
of the resource in question. One typical example may be a cold day where the sun heats
some of the turf modules, which then would not need further heating. Other turf modules
arranged in the shadow should be heated by opening valves that control the supply
of warm water and/or warm air. Advantageously, such individually controlled supply
of resources can take place automatically by means of a computer system which detects
the conditions of the turf at each turf module. Correspondingly, the computer system
can operate resource valves in the storage location.
[0023] The storage location can be a storage chamber provided with storage chamber environment
control means. A computer system is then adapted to control the storage chamber environment
control means on the basis of input from sensors in the storage chamber. The storage
chamber environment control means can typically comprise air heaters or coolers, air
humidifiers and/or air dryers.
[0024] According to a second aspect of the present invention, there is provided a method
of cultivating the turf of a plurality of turf modules that are adapted to constitute
a turf field of a sports stadium. The method comprises the following steps:
- a) establishing a connection engagement between a module resource connection and a
fixed resource connection; and
- b) through said connection engagement, supplying a turf resource to the turf.
[0025] A turf resource may include for instance water, temperated water, gas, temperated
gas, plant nutrition, electric power.
[0026] In a preferred embodiment, the method comprises the following steps:
c) disengaging the connection engagement between the module resource connection and
a fixed resource connection when the turf modules are on a fixed support base on which
they constitute the turf field;
d) moving the turf modules to a storage location;
e) establishing a connection engagement between the module resource connections and
fixed resource connections at the storage location.
[0027] With this method, the operator is able to move the turf modules to a location where
he in some embodiments is able to control the environment. Also, he is able to leave
the fixed support base available for events which require the turf field to be removed.
[0028] In yet another embodiment of the second aspect of the invention, step a) comprises
- i) establishing connection engagements between first module resource connections arranged
at a perimeter of a first set of turf modules and fixed resource connections arranged
at the periphery of the fixed support base;
- ii) establishing connection engagements between first module resource connections
of a second set of turf modules and second module resource connections of the first
set of turf modules; and
- iii) establishing connection engagements between second module resource connections
of the second set of turf modules and the module resource connection of additional
turf modules;
thereby connecting the turf modules of the turf field either directly or indirectly
to the fixed resource connections arranged at the periphery of the fixed support base.
[0029] With this method, an entire turf field may be arranged with turf modules which are
connected to turf resources, however without the need of fixed resource connections
in the fixed support base.

[0031] Fig. 1 is a principle drawing of a sports stadium 1 according to the present invention.
In this embodiment, the sports stadium 1 is equipped with a turf field 3 in the form
of a football field. The turf field 3 is made up of a plurality of turf modules 5
which are arranged closely together on top of a fixed support base 7. Encircling the
turf field 3 is a spectators stand 9, of which only parts are shown in Fig. 1.
[0032] Fig. 2 shows the same sports stadium 1 as in Fig. 1. However, in this situation the
turf field 3 is not assembled on the fixed support base 7. Indicated with dotted lines
is a storage location in the form of a storage chamber 11 below the fixed support
base 7. An aperture 13 exists in a portion of the fixed support base 7, through which
turf modules 5 can be transported between the storage chamber 11 and the fixed support
base 7. Below the aperture 13 is a not shown lift which is adapted to move the turf
modules 5 up and down through the aperture 13.
[0033] It should be noted that other storage locations 11 also are possible, for instance
a chamber remote from the stadium or even outside without any cover above the turf
modules 5.
[0034] In Fig. 2, on the fixed support base 7 one turf module 5 has been installed in its
correct position. Two additional turf modules 5 have been transported onto the fixed
support base 7 and are being moved towards their correct position. When the entire
turf field 3 has been made up by turf modules 5, the aperture 13 is closed with a
door (not shown) that is fixed in a position flush with the fixed support base 7.
[0035] In the storage chamber 11 there are a plurality of vertically stacked storage shelves
15, onto which turf modules 5 which are in a storage mode can be stored. As is indicated
in Fig. 2, one turf module 5 is about to be moved out from its storage position from
the lowermost shelf 15 in the storage chamber 11.
[0036] Also schematically indicated in Fig. 2 are fixed resource lines 17 which are fixed
to the fixed support base 7. The fixed resource lines 17 are arranged as parallel
lines which cover every position of the turf modules 5 when they are arranged in their
application mode on the fixed support base 7. The fixed resource lines 17 advantageously
comprises various types of lines for various resources, such as watering lines, heated
water lines, electric lines and air-conducting lines. Although they are visible in
Fig. 2, the fixed resource lines 17 can advantageously be arranged below the upper
face of the fixed support base 7, i.e. not possible to see.
[0037] Extending up from the fixed resource lines 17 are a plurality of fixed resource connections
19. In this embodiment there is arranged one fixed resource connection 19 at each
position of the turf modules 5 when they are in the application mode on the fixed
support base 7 (i.e. when they are in use as an assembled turf field 3). In the shown
embodiment, the entire turf field 3 is made up of 54 turf modules 5 (6 x 9). Hence
there are arranged 54 fixed resource connections 19. Since the fixed resource lines
17 do not extend across the aperture 13, the door (not shown) discussed above is provided
with corresponding fixed resource connections 19 and associated fixed resource lines
17.
[0038] Fig. 3 to Fig. 5 illustrate the process of moving a turf module 5 into an application
mode on the fixed support base 7, including connecting a module resource connection
21 of the turf module 5 to a fixed resource connection 19 below it. Fig. 3 shows a
turf module 5 which moves along a fixed support base 7 by means of wheels 23. In this
situation, the wheels 23 constitute the lowermost part of the turf module 5 and support
the remaining parts of the turf module 5. Centrally arranged in the turf module 5
there is a module resource connection 25 which connects to various module resource
lines 27 in the turf module 5. The module resource lines 25 are integrated in the
turf module 5, thus always being moved together with the turf module 5.
[0039] On top of the turf module 5 there is an upper face constituted by natural turf 28.
[0040] In the fixed support base 7 there is arranged a fixed resource connection 19 which
is connected to fixed resource lines 17, as discussed above with reference to Fig.
2. As appears from Fig. 3 the fixed resource lines 17 are arranged below the upper
face of the fixed support base 7, thereby being non-visible from above and well protected.
[0041] Fig. 4 shows the same components as Fig. 3. However the turf module 5 has been moved
into a position where the module resource connection 25 is arranged directly above
the upwardly facing fixed resource connection 19. The turf module 5 is now in its
correct position on the fixed support base 7. In order to engage the module resource
connection 25 with the facing fixed resource connection 17, the wheels 23 of the turf
module 5 are pulled up towards the turf module 5, making the turf module move downwards.
The downwards movement of the turf module 5 makes the module resource connection 25
move down towards the fixed resource connection 19. Fig. 5 shows the turf module 5
in a positon where the wheels 23 have been pulled up and the main body of the turf
module 5 has landed onto the fixed support base 7.
[0042] In this embodiment, actuators 29 are used to move the module resource connection
25 the last vertical distance towards and into connected engagement with the fixed
resource connection 19. Fig. 6 and Fig. 7 are enlarged portions of Fig. 4 and Fig.
5, respectively. In Fig. 6 the module resource connection 25 exhibits a vertical distance
from the fixed resource connection 19. A set of actuators 29, which in this embodiment
are pneumatic cylinders, are used to move the module resource connection 25 downwards
into engagement with the fixed resource connection 19. The engaged position is shown
in Fig. 7.
[0043] The actuators 29 may also be manually operated, or electrically or hydraulically
operated.
[0044] Visible in Fig. 6 are connection heads 31 on the module resource connection 25 that
enter receiving connection funnels 33 on the fixed resource connection 19.
[0045] When disengaging the module resource connection 25 from the fixed resource connection
19, the actuators 29 are operated in the opposite direction, thereby pulling up the
module resource connection 25 from its engagement. As will be understood by the person
skilled in the art, one can also imagine arranging the actuators 29 in association
with the fixed resource connection 19, and adapt the fixed resource connection 19
to move up and down into and out of engagement with the module resource connection
25 above it.
[0046] In an alternative embodiment, the engagement and disengagement of the module resource
connection 25 with the fixed resource connection 19 can be performed simply by lowering
or pulling up the wheels 23 of the turf module.
[0047] Pulling the wheels 23 up will lower the module resource connection 25, and by adjusting
the needed vertical distance and the vertical initial position of the module resource
connection 25, one can in this manner omit using actuators 29 for these engagements
and disengagements.
[0048] Fig. 8 is an enlarged perspective view of a module resource connection 25 and a fixed
resource connection 19. The turf module 5 and some of the fixed support base 7 are
omitted for illustrational purpose. The actuators 29 are also not shown.
[0049] The fixed resource connection 19 as well as the module resource connection 25 comprise
a main plate 26, 20. Depending from the main plate 26 of the module resource connection
25 are four guide pins 35 (barely visible) which are adapted to enter facing guide
funnels 37 provided in the main plate 20 of the fixed resource connection 19. The
guide pins 35 and the guide funnels 37 provides for mutual alignment between the main
plates 20, 26, ensuring proper engagement between the connection heads 31 and the
connection funnels 33.
[0050] When the turf modules 3 are not in their application mode on the fixed support base
7, covers (not shown) are advantageously arranged over the fixed resource connection
19 in order to protect it and in order to provide an even and useful surface. Thus,
the fixed support base 7 can be used for other purposes when the turf field 3 (i.e.
the turf modules 5) are not arranged on the fixed support base 7.
[0051] Fig. 9 is a schematic cross section side view of a pipe channel 39 recessed in the
fixed support base 7. A plurality of fixed resource lines 17 are arranged in the pipe
channel 39. Above the pipe channel 39 is a removable cover 41 which upon removal permits
inspection of the fixed resource lines 17. Also arranged below the same cover 41 is
an auxiliary channel 43 which may be employed if the user needs to arrange additional
piping in the fixed support base 7. An advantageous use of the auxiliary channel 43,
or a portion of the pipe channel 39, is drainage of water in a situation where the
turf modules 5 are not present on the fixed support base 7. Such a situation may e.g.
during a concert or a convention. Moreover, in such a situation, the fixed resource
connections 19 at the fixed support base 7 may advantageously be used by other equipment
than the turf modules 5, such as gear powered with electricity.
[0052] In addition to the fixed resource lines 17, as shown in Fig. 8 and Fig. 9, the pipe
channel 39 may also comprise lines which are not used by the turf modules 5. Such
lines can typically include electric power used when the turf modules 5 are arranged
on the fixed support base 7, for instance during a concert. Other lines can include
cooling lines for an ice rink.
[0053] Fig. 10 is a schematic top view of a turf module 5, with the position of the module
resource connection 25 indicated in a central portion of the turf module 5. Indicated
with a dotted line is an alternative localization of the module resource connection
25'. As will be understood, the position of the module resource connection 25 must
be adapted to the positions of the fixed resource connections 19, or vice versa.
[0054] Fig. 11 depicts with a schematic top view, an alternative embodiment to the one disclosed
above. In this embodiment the module resource connection 125 is arranged on a side
of the turf module 5. It connects with facing fixed resource connection 119, which
is one of a plurality arranged along a turf field periphery 50 which surrounds the
turf field 3. That is, in this embodiment, the fixed resource connections 119 are
not arranged in the fixed support base 7, however along the outskirts of the turf
field 3. Indeed, a combination of fixed resource connections 19, 119 arranged in the
periphery and in the fixed support base 7 can be imagined.
[0055] Preferably, mutual engagement between the module resource connection 125 and the
peripherally arranged fixed resource connection 119 is provided by moving them towards
each other in a substantially horizontal direction.
[0056] Fig. 11 depicts an embodiment wherein fixed resource lines 17 in the fixed support
base 7 are not used. Instead, the module resource lines 27 are used for transmitting
resources from one turf module 5 to adjacent turf modules 5. With dotted lines in
Fig. 11 an additional and adjacently arranged turf module 5 is arranged beside a peripherally
arranged turf module 5. The peripherally arranged turf module 5 connects to a fixed
resource connection 119 with a module resource connection 125. In addition the peripherally
arranged turf module 5 comprises an oppositely arrange module resource connection
125 that connect to the said adjacent turf module 5. In this manner, resources can
be distributed throughout the turf field 3 through rows of turf modules 5, without
the need for fixed resource lines 17.
[0057] In the embodiment of Fig. 11, the turf modules 5 comprise module resource lines 27
adapted to provide resources to the turf of the turf module 5, as well as resource
transmission lines 45 which are adapted to transmit resources from one module resource
connection 125 to an adjacent turf module 5, through another distant module resource
connection 125.
[0058] As will be appreciated by the skilled person, the solution outlined in Fig. 11 makes
the turf field 3, made up of the turf modules 5, suitable for installation outside
the sports stadium 1. It may for instance be temporarily be installed on a parking
lot or other suitable flat ground, if the user wants to move the venue for a sports
event, e.g. By providing temporarily fixed resource connections (119) he may still
be able to provide required resources to the turf, even if the turf modules 5 are
not installed on the fixed support base 7 or the common storage location.
[0059] Fig. 12 is an enlarged cross section view of the upper portion of a turf module 5.
More precisely, Fig. 12 shows the upper face, namely the natural turf, of a turf module
5. The module resource line 27 in this embodiment is a gas line, through which air
is distributed. The module resource line 27 connects to a plurality of smaller outlet
pipes 51 that extends upwards through the upper portion of the turf soil 53. Having
a plurality of such outlet pipes 51 distributed evenly about the turf modules 5, makes
the user able to influence the condition of the air above the turf field 3 by flowing
appropriately heated / cooled air through the outlet pipes 51. In addition, he may
control the temperature of the turf itself. One can also imagine using negative pressure
in the module resource line 27 in order to move air from the turf field into and away
from the field. This approach may cause fresh air from outside the sports stadium
to enter the stadium. Advantageously the outlet pipes 51 are small and flexible to
not represent hazard to persons on the turf field 3.
[0060] Fig. 13 is a schematic diagram which illustrates a computer system 100 which is adapted
for controlling the supply of resources to the turf modules 5. The diagram is divided
into five parts, namely a turf module 5 located on the fixed support base 7 (left
hand side of Fig. 13), the fixed support base 7, the computer system 100 (center part
of Fig. 13), the storage chamber 11, and a turf module 5 (right hand side of Fig.
13) in the storage chamber 11.
[0061] The computer system 100 comprises a computer or CPU 101 to which conventional user
interface such as a keyboard and monitor 103 are attached. Advantageously a hand-held
device, such as a smart phone 105 or a tablet computer can also communicate with the
CPU 101 through wireless communication.
[0062] The CPU 101 is connected to a plurality of various sensors, including sensors in
the turf module 5, such as temperature sensor 151, O
2-sensor 152 and humidity sensor 153. When the turf module 5 is arranged on the fixed
support base 7, the sensors 151, 152, 153 in the turf module 5 connect to the CPU
101 through a module sensor communication line 109 which extends between the CPU 101
and a fixed resource connection 19 in the fixed support base 7. The fixed resource
connection 19 is then engaged with the module resource connection 25. When the turf
module 5 is arranged in the storage chamber 11 (cf. Fig. 2), the sensors 151, 152,
153 connect through the module sensor communication line 109 and a fixed resource
connection 219 in the storage chamber 11, which is engaged with the module resource
connection 25. Thus, the computer system 100 is able to measure conditions of the
turf module 5 both in the application mode (on the fixed support base 7) and in the
storage mode (at a storage location, such as the storage chamber 11).
[0063] There are also advantageously arranged sensors in the storage chamber 11, such as
temperature sensor 155, O
2-sensor 156, and humidity sensor 157. These sensors 155, 156, 157 connect to the CPU
101 through a storage sensor communication line 111.
[0064] Also controlled by the CPU 101 is a module water supply valve 113. The module water
supply valve 113 is arranged in the turf module 5 and is controlled through a module
water supply valve communication line 115. The module water supply valve communication
line 115 extends between the CPU 101 on one side and the fixed resource connection
19 on the fixed support base 7 and the fixed resource connection 219 of the storage
chamber 11 on the opposite side.
[0065] The turf module 5 also comprises a module nutrition supply valve 117, which in a
corresponding manner connects to the CPU 101 via a control line 121 and through the
module resource connection 25 and the fixed resource connection 19 (or 219 if arranged
in the storage chamber 11).
[0066] In the fixed support base 7 there is arranged a plurality of fixed resource lines
15 in the form of heated water lines. The flow of heated water through these lines
is controlled by heated water control valves 123 which are controlled by the CPU 101
through heater water valve control line 127. In some embodiments the lines conducting
heated water can be adapted to guide the heated water in the fixed support base 7,
without guiding the water into the turf modules 5. That is, the turf modules 5 would
then be heated by convection from the heated fixed support base 7 to the turf modules
5. One could also use cold water for cooling the turf modules 5. In such embodiments
a fixed support base temperature sensor 129 can be arranged in the fixed support base
7, and connect to the CPU 101 through a support base temperature communication line
131.
[0067] In the storage chamber 11 there can advantageously be arranged storage chamber environment
control means 133, such as air heaters or humidity control means. Typically, the storage
chamber environment control means 133 will be operated based on input from the sensors
155, 156, 157 in the storage chamber 11. Thus, the operator is able to set a desired
set of environmental parameters in the computer system 100 in order to obtain desired
growth of the turf during storage. In some cases, the operator may want the turf to
grow as fast as possible to repair damages from an earlier event, such as a football
match. In other cases, he may want to prepare the turf for particularly cold or warm
weather. In such cases he may want to make the conditions in the storage chamber similar
to the outside weather, in order to reduce the climatic difference experienced by
the turf when moved onto the fixed support base 7.
[0068] In order to cultivate the turf, the user may in some cases find it advantageous to
arrange some turf modules 5 in a sunny portion of the fixed support base 7, while
he may want some remaining turf modules 5 to be arranged in the storage chamber 11.
Advantageously, by means of the computer system 100 discussed under reference to Fig.
13, each turf module 5 which is connected to a fixed resource connection 19, 119,
219, can be operated independently. Thus, the computer system 100 can be used to cultivate
