CONVERTIBLE FLOOR SYSTEM
Abstract
A system is provided for quickly converting a floor area from
one surface to another. A hard floor, typically wood, as for
dancing, is covered by one or more detachable carpet sections
located within an otherwise fully carpeted floor area. The carpet
sections can be detached and removed to convert the underlying area
into a dance floor. In one embodiment grooves are formed in the
underlying floor and contain felt strips which lock with
detachable, flexible locking strips attached to the carpet sections
and which lock therewith when the carpet is installed. Hardened
insert strips overlay the felt strips when the carpet is removed to
provide a flat, smooth dancing surface.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to floor systems and more
particularly is directed towards a floor system that is quickly
convertible from a fully carpeted area to a smooth, hardwood, floor
area.
2. Description of the Prior Art
Most modern restaurants install wall-to-wall carpeting in their
dining and lounge areas, not only for decorative effects but also
for the comfort of the patrons and the sound absorbtion
characteristics provided by carpeting. Those restaurants that
feature dancing normally have a special hardwood floor area set
aside and restricted to dancing only. Generally the hardwood floor
areas are rather expensive and used only for dancing. The
restaurant owner does not normally use this area for anything but
dancing for the reason that if tables or chairs were placed on this
floor during those times of day when there is no dancing, the floor
finish would be marred by the furniture legs and stained by spilled
food. As a result, that portion of the restaurant is unused for
long periods of time as during breakfast or lunch when there
normally is no dancing. The restaurant owner thus loses the
possibility of increased patronage during certain periods of the
day and also reduces his seating capacity for special events such
as meetings, banquets and the like.
Accordingly, it is an object of the present invention to provide a
convertible floor system whereby a floor area can be quickly and
easily changed from a smooth, hardwood surface for dancing or the
like to an area that is fully carpeted and blended into other
adjacent carpeted areas.
SUMMARY OF THE INVENTION
This invention features a convertible floor system, comprising a
floor area, hardwood flooring over at least a portion of said floor
area, fixed carpeting over a portion of said floor area and
detachable carpeting overlaying said hardwood flooring, said
hardwood flooring being bounded by grooves, strips of one portion
of a flexible connector secured in the grooves, strips of another
portion of the flexible connector marginally bonded to the
removable carpet sections for detachably installing said carpet
sections to said hardwood flooring, and hardened smooth strips
removably mounted in said grooves over said one portion of
connectors to form a flush flooring surface upon removal of said
carpeted sections.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, the reference character 10 generally
indicates a hard floor area, typically wood, covered by carpeting
12, normally inlaid in a wall-to-wall manner. Within the
permanently carpeted floor area is a convertible area bounded by
the line 14. This area is convertible from a hardwood flooring 16
to a carpeted area 18, the carpet section overlaying the flooring
16 being removable.
In the illustrated embodiment, the convertible area includes two
adjacent hardwood floor sections 16 although single or multiple
hardwood floor sections can be utilized according to particular
requirements. Typically, the convertible area is rectangular in
outline although other configurations are possible.
As shown, the hardwood areas 16 are defined by shallow marginal
grooves 20 extending all about the areas 16 and between adjacent
areas. Seated in the grooves 20 is a strip 22 of felt or similar
material, permanently set in place and forming one half of a strip
connector of the sort sold under the trademark "Velcro." Velcro
fasteners are comprised of two parts, one being a non-woven
material such as felt and the other part being comprised of a
flexible material 24 provided with a plurality of small hook-like
loops 26 of a stiff resilient plastic material, such as nylon,
projecting from the face of the material. When the two sections are
pressed together, these hooks lock with the fibers of the felt,
holding the two parts together. The parts can be separated by
peeling one away from the other as suggested in FIG. 1. The
connection and separation may be repeated indefinitely.
The felt strip 22 is thinner than the depth of the recess 20 to
provide clearance to accommodate the cooperating hooked strips 24
marginally bonded to the underside of the carpet sections 18
whereby, when the carpet section 18 is in position, the upper
surface thereof at the seams will be smooth and flush with the
fixed carpeting as best shown in FIG. 3. As also shown in FIG. 3,
when the carpet section 18 is laid down, the hooked strips 26 will
lock with the felt strips 22, securing the carpet section firmly in
position to prevent accidental displacement thereof. With the
carpet section 18 installed, the entire floor area will be carpeted
in a continuous manner so that in a restaurant, for example, all of
the floor area will be available for setting up tables and chairs
or otherwise making maximum use of the available space.
When the convertible area is to be utilized for dancing purposes,
for example, the carpet sections 18 are peeled back as shown in
FIG. 1, separating the hooked strips 24 from the felt strips 22 and
exposing the underlying hardwood flooring as shown in FIG. 2.
Smooth, hard thin strips 28 are then placed in the grooves to form
a flush continuous surface as shown in FIG. 2. In the preferred
form of the invention, the strips 28 are fabricated from a
laminated plastic material such as that sold under the trademark
"Formica" to provide a very smooth, hard, durable finish
corresponding to that of the hardwood surface 16.
The area may be quickly and easily converted back into a carpeted
area by merely removing the strips 28 and replacing the carpet
sections.
Referring now to FIG. 4 of the drawings there is illustrated a
modification of the invention and, in this embodiment, members 30,
preferably elongated flexible magnetic strips, are attached along
the inner margins of the removable carpet sections 18. Magnetically
attractive parts, such as steel nails 32, are secured in the groove
to detachably engage the carpet margins.
Referring now to FIG. 5, there is illustrated a further
modification of the invention and, in this embodiment, removable
carpet section 18" are provided with flexible magnetic strips 34
attached along the inner marginal carpet faces. Typically, the
strips 34 are a magnetic vinyl (PVC) material sold by 3 M
Corporation under the trademark "Plastiform." Preferably the strip
is approximately 0.060 inch thick and 1 inch wide and backed by a
pressure sensitive adhesive. Co-operating magnetically attractive
inserts 36 are fastened to the floor in sockets or grooves
depending upon the configuration of the inserts.
The inserts may be in the form of steel cylindrical plugs,
typically 1 inch in diameter by 3/4 inch in length spaced
approximately on 4 inches centers, or a steel strip, typically 1
inch wide by 1/4 inch thick. In either case the insert is flush
with the floor surface so that the floor remains flat.
Referring now to FIG. 6, there is illustrated yet another
modification of the invention and, in this embodiment, removable
carpet sections 18" are detachably connected by means of "Velcro"
strips with a relatively wide band 24' which may be the felt or
hook portion permanently attached to the bottom marginal edge of
one carpet section. The band 24' extends beyond the edge of the
carpet section and detachably connects to a cooperating band 22',
which may be hooked or felted depending upon the band 24',
permanently attached to the bottom marginal edge of the adjacent
removable carpet section. Around the border of the area covered by
the removable carpet sections is a metal strip 34 nailed to the
floor over the edge of the fixed carpet 12'. The metal stip covered
by a layer of felt 22" and the bottom margin of the movable carpet
18" provided with a hooked band 24" for detachable connection.
