MODULAR FLOOR TILES AND FLGOR SYSTEM
BACKGROUND OF THE INVENTION
The present invention relates generally to a modular tile and
modular tile system. More specifically, it relates to a modular tile and
modular tile
system installed on an existing floor.
Work environments are becoming increasingly sophisticated due to
an increasing need for utilities necessary to service the environment
including
power, data and communications networks. Often, these environments must
distribute power to tools such as computers, printers and the like. In
addition,
many environments must distribute data and communications cabling to support
interoffice electronic mail, world-wide interne~t connectivity, and in-house
intranet
connectivity. An important consequence of 'this increased sophistication in
work
environments is the incr~:ased need for distributing and managing cabling in
an
efficient, safe and aesthetically appealing manner.
Another demand often placed ~on modern work environments is the
need to be easily configured and reconfigured to keep in stride with the
fluctuating demands and influences in the work place.
One solution to providing increased volumes of power and data
cabling throughout an office environment is to create a raised floor) namely a
floor built a distance above the existing floor to thereby provide a space for
cabling between the two. Some raised floors are architectural, i.e. are
installed
when the building is built, and include a series of relatively large panels)
some of
which can be lifted to gain access to the space. Other raised floor systems
are
" installed later and comprise a gridwork of supports and panels or tiles
which are
installed over this gridwork. An example of such a pieced-together system is
shown in U.S. Patent No. 4,593,499 to Kobayashi et al.
Typically) both types of raised floors, namely the architectural and
the pieced-together, are installed by skilled tradespersons having special
tools,
CA 02272253 1999-OS-18
WO 98/24990 PCT/US97/22633

equipment and training. Naturally, providing adequate support and proper
leveling are important concerns. As a consequence, the installation andlor
reconfiguration of the conventional raised floor is often costly. Moreover)
work
environment elements can not be easily configured and reconfigured with the
typical raised floor.
Also, because raised floors are most often installed in a wall-to-wall
configuration, a facilities planner must commit to equipping the entire work
space
with a raised floor) rather than equipping only that portion with the
requirements
justifying a raised floor. This fact reduces the utility and adaptability of
raised
floors to certain work environments, especially those that have a need to
equip
some work stations one way for some of its workers and some another way for
others of its workers. In particular, it would be desirable in some work
environments to create platforms of a raised floor to meet the needs within
that
part of the work environment.
The conventional raised floor often lacks specific cabling
management capabilities. For example) in some systems, the cabling is not
isolated from one another nor managed separately within the floor. This can
create interference and noise problems between power, communication, and
data cabling.
SUMMARY OF THE INVENTION
Briefly stated, the present invention is directed to a modular tile and
modular tile system.
The modular tile has a base structure having a generally horizontal
portion and four support legs. The legs engage the existing floor and support
the
horizontal portion above the floor thereby providing a lower chamber between
the
existing floor and the horizontal portion. The tile also has four upper column
members and a cover supported by the upper column members a distance
above the horizontal portion thereby creating an upper chamber.

In another aspect of the invention, a system of tiles have at feast
four modular tiles arranged so that a corner' of each of the tiles meet at a
common point. The tiles comprise a base structure having a generally
horizontal
portion, a connecting point at each corner, .and four support legs engaging
the
existing floor thereby creating a lower chamber. The lower chamber is adapted
to receive cabling. Four upper column members extend above the horizontal
base structure. A cover is supported by the upper column members and creates
an upper chamber adapted to receive cabling. A tile connect engages adjacent
connecting points to releasably connect the modular tiles.
In another aspect of the invention, a system of tiles on which a work
environment is confgured is provided. The work environment includes elements
such as panels, screens, work surfaces, storage cabinets, ramps, and lights.
The system has a plurality of tiles arranged across the existing floor to
create a
platform. Each tile has a bottom portion and a top portion. The top portion
includes an array of apertures adapted to receive a protruding portion of an
indexing element associated with a work environment element.
In another aspect of this invention, a system distributes electrical
power in a work environment. The system includes an electrical connector
receiving electrical power from an power source. A first modular tile has a
circuit
defined by a first and a second conductor. The first circuit receives the
electrical
power from the electrical connector. A second modular tile has a circuit
defined
by a first and a second conductor. A modular tile connect electrically
connects
the first circuit with the second circuit such that the electrical power
received by
the first circuit energizes the second circuit.
The present invention provides significant advantages over typical
raised floor tiles and raised floor tile systems. The preferred present
invention
provides a modular floor tile with exposed edges. The preferred modular tiles
are
easily configurable, enabling efficient distribution and management of
cabling.
The term cabling is meant to refer to cables and wires including power) data
and
utilities servicing a work environment and corresponding work environment

elements. The term work environment element is meant to include elements
such as work surfaces, panels, screens, storage cabinets, ramps and the like.
Work environment elements could also include powered devices such as
computers, lights, sound booms) powered panels, screens, work surfaces and
the like.
The preferred present invention is modular in that it is configurable
and can be quickly connected and re-connected.
The present invention also relates to modular tile platforms or
islands configured from the modular tiles. Modular tile platforms can be used
for
a variety of activities including stand up activities, dynamic mobile office
chair
based activities, low level sofa activities, mini-conferencing) mini-waiting
area)
team grouping and manager to secretary interfacing. By modular platform it is
meant that the connected modular tiles comprise a floor which is not
necessarily
installed wall-to-wall. Preferably) the modular tiles are self supporting and
are
not structurally confined to architectural wafts. Therefore, the preferred
modular
tile platform need not abut an architectural wall.
The modular tile platform environment can provide related
economic benefits. For example, in certain types of lease situations) the
modular
tiles can provide a tenant improvement and therefore specific leasehold
advantages. The tiles can also be quickly reconfigured for a new tenant.
Moreover, such a tile scheme is usually easily transported by the tenant for
rapid
deployment in the next installation. With its on-site capacity and ability to
support
the frequent transitions associated with temporary or visiting work
environments,
the modular environment can enhance the benefits of rental and lease
opportunities.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, FIG. 1 is a perspective view of a modular
tile 95 incorporating the preferred embodiment of the present invention.
Modular
tile 95 is preferably exposed along its edges and installed on top of an
existing
floor 38. FIG. 2 is a perspective view of a modular tile platform 39
configured
using the modular tile shown in FIG. 1. As shown in FIG. 2, the side edges of
the
modular tile platform 39 is preferably formed by the tiles themselves, thus
leaving
the side edges of the outermost tiles exposed. This is preferred for
simplicity of
the design, appearance and function of the platform.
In an alternative, less preferred embodiment, a trim is provided to
cover the side edges of the outermost tiles. Such a trim may be provided in
lengths equal to the length of the individual tiles. Alternatively) the trim
may be
provided in longer lengths to cover the side edges of multiple tile. Such tong
lengths of trim may also be made to be cut in the field to the desired length.
In addition, a ramp 370 may also be provided along the edges of
the modular tile platform. Such ramps are discussed below in connection with
FIGS. 33-35.
FIG. 3 is a partial side view of the modular tile platform shown in
FIG. 2. F1G. 3 shows the modular tile 95 connected to two modular tiles 91,
93.
FIG. 4 is an exploded view of modular tile 95 shown in FIGS. 1-3.
Referring to FIGS. 1-4) modular tile 95 preferably comprises a
square top portion 575 and a square bottom portion 585. The general
dimensions of the preferred modular tile is 18 inches in width and 18 inches
in
height. Top portion 575 comprises an insulating member 631, cover 621 and
floor covering 601. Bottom portion 585 comprises a base structure 641, tile
connects 301, 401 or 501, corner members 800 and horizontal portion members
900. These elements can be more clearly described with reference to FIGS. 3
and 4.
CA 02272253 1999-OS-18
WO 98I24990 PCTlUS97/22633
FIG. 3 shows a complete side view of modular tile 95 and a partial
side view of modular tiles 91 and 93. Modular tiles 91 and 93 are generally of
similar structure as modular tile 95. Modular tile 95 is connected to modular
tile
91 and modular tile 93 via modular tile connect 475 and 99, respectively. Also
shown is cabling 2, and 4. Cabling 2, 4 can be efficiently installed
underneath
the modular tile 95 since the tile 95 is preferably exposed along each of its
edges. In this preferred embodiment, cabling 2 provides power and cabling 4
provides communications.
Base portion 585 is installed on top of existing floor 38 and defines
a lower chamber 85. Top portion 575 resides on bottom portion 585, thereby
defining an upper chamber 75. Both chambers.75 and 79 are adapted to receive
cabling, electrical devices 1 and the like. Electrical devices 1 receivable in
either
chamber 75 or 79 include transformers, junction boxes) outlet boxes, wiring
harnesses and other like electrical devices. Preferably, lower chamber 85
defines
two channels 87) 89 and upper chamber 83 defines two channels 74) 75. Power
cabling 2 is installed in channels 85, 89 and communications cabling 4 is
installed in channel 75. Alternatively, as shown in FIG. 3, cabling 83 is
managed
between two connected modular tiles 95, 93 and underneath modular tile
connect 99.
Separating the power cabling 2 from the communications cabling 4
results in a number of advantages. For example, separation provides an easier
method of troubleshooting if utilities maintenance is required. It also
minimizes
the risk of electrical interference. Moreover, installing the higher voltage
cabling
2 in lower chamber 85 reduces the risk of electrical exposure to occupants of
the
work environment.
FIG. 4 is an exploded view of the modular tile 95 shown in FIGS. 1-
3. Preferably, base portion 585 includes a generally rectangular base
structure
641 having a generally horizontal portion 643. FIG. 5 is a top view of base
structure 641. Preferably, horizontal portion 643 has various sets of holes,
upper
column members, and support legs.

of holes 120, a second set of holes 140, a third set of holes 910 and a fourth
set
of holes 810. These sets of holes serve a number of beneficial purposes. For
example) using holes 120, cabling installed on top of or beneath horizontal
portion 643 can be secured using a cable tie (not shown). Holes 120 also allow
cabling installed in either upper chamber 75 or lower chamber 85 of the
assembled tile 95 to be accessed and pulled through horizontal portion 643.
Therefore, installed cabling can be managed in both upper and lower chambers
75 and 85 within one modular tile and can be re-installed or re-managed
without
having to re-install the entire base structure 641.
Holes 120 also decrease the amount of material required for the
base structure 641, thereby reducing manufacturing costs. The resulting
modular tile 95 is also lighter and easier to manipulate and install. Holes
120
also increase the flexibility of base structure 641 so that it can conform to
surface
inconsistencies in the existing floor. Preferably, horizontal portion 643
comprises
a second set of holes 140. Holes 140 provide similar advantages as holes 120.
Preferably, as shown in FIGS. 4 and 5, horizontal portion 643 has a
third set of holes 910 and a fourth set of holes 810. Third set of holes 910

the upper chamber thereby defining channels for installing and managing
cabling
and other electrical devices. They also increase the rigidity and strength of
the
modular tile 95.
Preferably, the additional upper column members comprise both
horizontal portion members 900 and corner members 800. Third set of holes 910
are adapted to releasably affix the horizontal portion members 900 to the
horizontal portion 643. Base structure 641 has five horizontal portion members
900 (only one shown in FIG. 4). Preferably, one horizontal portion member 900

Returning to FIG. 4, base structure 641 further comprises at least
four support legs 745, 747, 749 and 751 which preferably support an individual
modular tile 95. Alternatively, the support lega support more than one modular
tile. For example, a support leg may be a unitary device positioned at a
common
point where two or more modular tiles meet. At this common point, one leg
would
support a corner of each of the modular tiles.
CA 02272253 1999-05-18
WO 98/24990 PCT/US97/22633
-14-
Support legs 745,' 747) 749 and 751 are preferably integral with
base structure 641. Preferably, upper column members 645, 647, 649 and 651
are integral with support legs 745, 747, 749 and 751, respectively. In a more
preferred embodiment) support legs 745, 747, 749 and 751, and upper column
members 645, 647, 649 and 651 are integral with base structure 641. Most
preferably, base structure 641, support legs 745, 747, 749 and 751 and upper
column members 645, 647, 649 and 657 are made in one piece.
A spacing member 775 is disposed on each leg 745, 747, 749 and
751 and protrudes laterally away from the surface of the leg. Spacing member
775 cooperates with the support legs on adjacent modular tiles such that the
legs
are positioned a predetermined distance from one another. For example, as is
shown in FIG. 3, the support legs of connected modular tiles 91, 95 and 95) 93
are positioned a predetermined distance from one another by spacing members
775. Spacing member 775 is preferably made from the same piece of material
as the legs 745, 747, 749 and 751. Alternatively) a spacing member is a
different
piece of material which is rigidly affixed to the leg.
Spacing member 775 provides a number of advantages. For
example, in the preferred embodiment, by spacing side by side connected
modular tiles a predetermine distance from one another, installation will
usually
require less labor. In addition, because installed modular tiles only touch
one
another at the spacing member rather than along an entire edge of the modular
tile, a modular tile can oftentimes be taken out of an assembled platform
without
having to disconnect and/or remove other connected modular tiles. Furthermore,
by spacing the modular tiles a constant, predetermined distance from one
another) a heightened aesthetic appearance of a connected modular tile
platform
can be achieved.
In an alternative embodiment, support legs 745, 747, 749 and 751
comprise a leveling member 790. FIG. 30 is a partial sectional side view of a
modular tile platform similar to the platform shown in FIG. 19 and includes a
leveling member disposed on the support legs of the modular tiles. FIG. 30

shows two modular tiles 91, 95 connected to one another via a modular tile
connect 99. Modular tiles 91, 95 are installed over existing floor 38. Modular
tiles 91, 95 have support legs 795. Preferably, support legs 795 comprise an
outer shell 796 and a retaining member 791. The retaining member 791 retains
the leveling member 790 within the support I~ag 795.
Preferably, leveling member 790 is a slow reaction member which
absorbs uneven surfaces on existing floor 38. The leveling member preferably
includes a sack made of a flexible) preferably non-elastic polymer such as a
thermoplastic polyurethane compound or the like. The sack is filled with a
viscous material, such as a gel, which flows quite slowly. Alternatively, the
sack
can be frlled with particulate matter which'shifts and flaws under pressure.

structure
641, and a second conductor 708 disposed between insulation member 631 and
a cover 621. First conductor 702 and a second conductor 708 together define a
circuit 709. Modular tile 91 has a similar construction as modular tile 95.
Tile
connect 475 preferably connects a first circuit of modular tile 97 to a second
circuit of modular fife 95.
The mechanical characteristics of connect 475 are similar to the
previously described modular tile connects 301, 4D1 and 501. Tile connect 475
comprises a top surface 436, a bottom surface 438, a first and a second

436 and extends from the first upwardly directed pin 444 to the second
upwardly
directed pin 445. Second conductor 439 is embedded in connect bottom surface
438 and extends from the first downwardly directing pin 440 to the second

When the modular tile 95 cover 621 is installed over base structure
643, upwardly directed pin 445 releasably engages a cover downwardly facing
hole 44T and thereby engages second conductor 708 residing between cover
621 and insulator 631. More preferably, first conductor 437 at upwardly
directed
pin 445 mates with a connecting point 736 of conductor 708. This electrical
connection results in first conductor 437 being at the same electrical
potential as

modular tile 91 by way of electrical connect 475.
Preferably) modular tiles connected together in a modular tile
platform configuration define a power grid. E3ased on the configuration of the
modular tile platform, the power grid may extend throughout an entire platform
or

computers, calculators, lamps or other similar type tools requiring low
voltage
D.C. power.

four-way connects 325, 330 or the two-way connects 425, 430 shown in FIG. 18.
Alternatively, connect 475 represents a general side view of a three-way
connect.
In an alternative embodiment) a modular tile without a first and a
second horizontal conductor is connected to ;~ conducting modular tile. For
example, a platform such as the one shown in FIG. 2 may have both conducting
and non-conducting modular tiles connected to one another. Electrical power
can then be distributed according to the previously described method only to
the
conducting modular tiles. Electrical power can therefore be selectively
distributed among modular tiles by using an electrical modular tile connect
475.
Together, the first conductor 70~? and the second conductor 708
define a circuit 709. Once energized) circuit 709 distributes electrical power
to
the various conductor connecting points 734) 735 and 736 within a modular
tile.

provides
power to an electrical connector 997. Electrical connector 997 has two leads
998, 999 which are connected to the first and second conductors 702) 708,
respectively. Alternatively, the transformer 996 connects directly to the
conductors 702, 708. Transformer 996 either isolates or steps-down the
incoming power from the exterior source 995. The transformer 996 or the
electrical connector 997 are installed either on top of the modular tile 91 or
within
one of the modular tile chambers.

FIG. 26 is a perspective view of a platform work environment 20
incorporating still another preferred embodiment of the present invention.
Platform environment 20 comprises a modular tile platform or island 30,
various
work environment components installed on modular tile platform 30, and cabling
2 and 4 servicing environment 20.
Platform 30 comprises a plurality of connected modular tiles 95. As
shown in FIG. 26, modular tile platform 30 comprises twenty-five (25) modular
tiles 95 connected in a matrix configuration. FIG. 27 is a top view of
platform
work environment 20 shown in FIG. 26. FIG. 28 is a side view of platform work
environment 20 shown in FIGS. 26-27.
Referring to FIGS. 26 and 27, platform 30 is installed on top of an
existing floor 10 which can be a new construction foundation floor. In these
types of installations, the modular tiles 95 are connected to one another to
define
specific zones and work areas defined by the building structure.
Alternatively,
platform 30 can be installed on top of an already existing raised floor pane!
system. In these types of retrofit applications, installation of the platform
30 is
simplified since the existing floor 10 need not be disassembled or
reconfgured.
As shown in FIGS. 26 and 28, the modular tiles 95 are exposed along their
edges. Therefore, the assembled modular tile platform 30 is preferably exposed
along its edges.
The modular tiles 95 making up the platform 30 are connected in
various configurations depending on the logistical and surface area
requirements
of the platform 30. For example, in the embodiments shown in FIGS. 26 and 27,
modular tiles 11) 13, 15 and 17 are arranged adjacent one another so that a
respective corner of each of the tour tiles 11, 13, 15, and 17 meet at common
point 19. Specifically, corner 21 of tile 11, corner 23 of tile 13, corner 25
of tile 15
CA 02272253 1999-OS-18
WO 98/24990 PCT/US97/22633
-31 -
and corner 27 of tile 17 meet one another at common point 19. This four tile
arrangement is duplicated throughout the platform 30 until the requisite work
environment surface area is configured.
Where two adjacent modular tiles 95 are arranged at the outer
boundaries of the platform 30) the tiles each have a respective corner which
meet at a common point. For example, outer corner 31 of modular tile 11 and
outer corner 33 of modular tile 13 meet one another at common point 29. Where
these two tiles meet, they are connected via a two-way connect as shown in
FIGS. 12 and 13. Alternatively, modular tiles 95 are configured so that a
corner
of only three tiles meet at a common point and form an "L" configuration.
Where
these three tiles meet, they are connected via a three-way connect as shown in
FIGS. 10-11. Modular platforms incorporating an L configuration are provided
in
the composite work environment 100 shown in FIG. 29.
FIG. 29 is a top view of a composite work environment 100
incorporating another preferred embodiment of the present invention. Composite
work environment 100 defines an entire floor of a building 102. Alternatively)
environment 100 defines only a portion of an entire floor.
As shown in the composite work environment 100 of FIG. 29, it is
not required to cover the entire existing floor 101 with the modular tiles 95.
Rather, a plurality of the tiles 95 are installed in a stand alone fashion to
configure the modular platforms 40, 70) 80 and 90 which are suited for work
environments supporting a limited number of personnel.
Composite work environment 100 comprises four isolated platform
environments 40) 70, 80, and 90 all having unique configurations. Environments
40 and 70 are generally rectangular type platforms) similar to the platforms
shown in FIGS. 26) 27 and 28. Platform environment 40 comprises twenty (20)
modular tiles 95 configured in a five-by-four matrix. Platform environment 70
comprises forty (40) modular tiles 95 configured in a five-by-eight
rectangular
matrix.
CA 02272253 1999-05-18
WO 98I24990 PCTIUS97/22633
-32-
Platforms 80 and 90 utilize the three tile approach in forming an L
configuration. For example) in work environment 80, connected modular tiles
56)
57 and 58 and modular tiles 48, 49 and 50 form a three tile L configuration.
Similarly, in work environment 90, connected modular tiles 62) 63 and 64 form
an
L confiiguration. Either of the work platforms 40) 70, 80 or 90 can be
extended in
width or length based on changing work environment requirements.
Alternatively, platform environments 40, 70, 80 or 90 are installed in
the typical wall-to-wall configuration (not shown). In this alternative
embodiment,
a single platform is extended in length and width to cover an entire existing
floor.
Alternatively, existing modular platforms 40, 70, 80 and 90 are extended
thereby
tying all four modular platforms 40, 70, 80 and 90 into one work environment.
The modular tile platforms shown in FIGS. 26-29 comprise modular
tiles having square covers. FIG. 36 shows an alternative embodiment of a
modular tile platform wherein the modular tile covers have an hexagonal shape.
FIG. 37 shows another alternative embodiment of a modular tile platform
wherein
the modular tile covers have a rectangular shape. In this preferred
embodiment,
the modular tiles are arranged adjacent one another so that a respective
corner
of the four tiles meet at a common point. Alternatively, as shown in FIG. 38,
the
modular tile covers having a rectangular shape are staggered in an off set
fashion such that only two corners of the two modular tiles meet at a common
point.
Returning to FIGS. 26-28) work environment 20 comprises a
number of work environment elements including a work surface 3, a sound boom
5, a light 7, a chair 9, a chair bump 8) a foot rest 13 and a movable wall 6.
Other
possible elements include water coolers) fans, noise cancellation devices,
intelligent lap top power supplies) storage components, podiums, chairs,
lighting,
ambient task lighting and integrally lit free standing panels. Preferably,
these
elements are indexed within the modular tile platform utilizing the preferred
indexing means as previously described and shown. These work elements
CA 02272253 1999-OS-18
WO 98l24990 PCT/US97122633
-33-
preferably have at least one indexing element having a protruding portion (not
shown in FIG. 26) which is releasably affixed to a modular tile.
To support these elements and other associated electrical devices,
power, data) voice and other utilities must be brought to and distributed
throughout the modular tiles and therefore the platform. Cabling 2 and 4
servicing work platform 20 are communicated to modular environment 20 in a
number of different ways.
FiG. 29 shows various schemes for providing the cabling to and
from the modular platforms 40, 70, 80 and 90. Cabling 2 supplies standard low
voltage electrical power (i.e., 115/120 Vac). In an alternative embodiment,
cabling 2 provides higher voltage electrical power {e.g., 240 Vac) and work
environments 40, 70, 80, and 90 have transformer means for transforming this
higher voltage. Alternatively, cabling 2 provides low voltage direct current
power
(i.e., 5-50 Vdc). Power and communications cabling and other electrical
devices
(i.e., AC/DC transformers) are installed either underneath, within or between
connected modular tiles.
Work environment utilities are supplied from an existing utilities
service within the work environment or from adjacent work environment zones
and transmitted to the work platform in a number of different ways. In a
preferred
embodiment, modular platforms receive electrical power from an exterior
source.
For example, as shown in FIG. 29, work environment 70 receives electrical
power via cabling 51 from exterior source 61. Exterior source 61 may be a load
center, a control panel, or a branch circuit access point (or junction point)
within
the work environment building or in a remote electrical room. Preferably, the
electrical power transmitted via cabling 51 is 115I120 VAC.
In an alternative embodiment, work environment 70 comprises
transformer means 66 which isolates incoming electrical power supplied by
exterior source 61. Alternatively, transformer means 66 steps down the
incoming
electrical power. Transformer means 66 is installed either underneath, on top
of
or within the tiles making up modular platform 70. A platform can also receive
CA 02272253 1999-OS-18
WO 98/24990 PCT/US97/22633
-34-
electrical power from another modular platform. For example, work environment
80 receives electrical power from work environment 70 via cabling 53.
Communication or data cabling 4 is installed in each work platform.
This cabling is necessary for transmitting communications information to work
platforms to service facsimile, computer networks (i.e., Internet and Intranet
capabilities), phone lines and modems. Communication cabling 2 can be pulled
from one work environment to another. This cabling scheme is preferred where
various environments must be networked with one another (e.g.) LAN) Internet,
Intranets, e-mail) etc.).
In a preferred embodiment, communication or data information
originates from an external source 67 and is transmitted to work platform 80
via
cabling 41. From platform 80, this information is transmitted via data cabling
41
to work environment 80 and can be further re-transmitted to other work
platforms.
In composite environment 100) communication and data information transmitted
via cabling 41 is sent to work platform 70, 90, and 40 via communication and
data line cabling 43, 45, and 47, respectively. Alternatively, work platforms
40)
70, and 90 receive communication information from separate exterior
communications sources.
FIG. 33 shows stilt another alternative embodiment of the present
invention. FIG. 33 shows a modular tile platform 360 comprising a plurality of
connected modular tiles 95 and a modular tile platform ramp 370. Ramp 370 is
connected to the modular tiles 95 within the modular tile platform 360 such
that
the resulting modular tile platform work environment 365 maintains a generally
rectangular configuration. Preferably, ramp 370 has a length and a width
equivalent to the length and width of four modular tiles connected in a
generally
rectangular platform. Therefore, as shown in FIG. 33, ramp 370 is connected to
two modular tiles 95. Ramp 370 is connected to the two modular tiles via a two-
way modular tile connect and a three-way modular tile connect.
F1G. 34 shows an alternative embodiment of the modular tile
platform shown in FlG. 33. FIG. 34 shows a modular tile platform 350

to two modular tiles 95 via a two-way modular tile connect and a three-way
modular tile connect. In this alternative embodiment, ramp 370 is connected to
the generally rectangular modular tile platform 350 along an exterior edge
357.
FiG. 35 is a sectional side view of the connected modular tile
platform ramp 370 taken along the line 34-34 as shown in FIG. 34. FIG. 35
shows the ramp 370 adjacent a modular tile 95 and installed over an exiting
floor
38. Ramp 370 is connected to modular tile 95 via modular tile connect 378.
Preferably, the ramp 370 has the same height as the tile 95. The ramp 373
comprises an incline 371 and is supported b~,r a plurality of ribs 373. The
ramp
incline 371 is preferably covered with a floor covering 372. The floor
covering
372 has ridges 373 which prevents slipping along the incline. The ramp 370 is
preferably made from extruded aluminum. Alternately) the ramp 370 is a die
cast
of aluminum alloys. The ramp 370 facilitates accessing a modular tile platform
for wheeled carts, wheelchairs and chairs. .
