PREFABRICATED FLOORING
Abstract
A resilient flooring or carpeting is mounted on a slat-like
structure. The individual slats are not bonded together and are
securely fastened to the underside of the flooring. The floor
material is sufficiently resilient to permit the flooring with the
slats attached thereto to be rolled in a large roll. When the roll
of material is laid out on a flat support, the individual slats
abut adjacent slats and form a subfloor for the flooring which is
bonded to the slats.

Claims
What is claimed is:
1. A roll of prefabricated flooring consisting of a two-part
laminate structure, the upper laminate structure being a vinyl wear
layer and a foam backing layer, used to provide the decorative and
wear surface of a floor, and the second laminate structure being a
plurality of approximately 3/4 inch thick hardboard slat elements
which are fastened to the underside of the upper laminate
structure, said slat elements being otherwise unsecured, to each
other and being so positioned relative to each other that when the
flooring is in a single plane the sides of two adjacent slat
elements abut each other and are in contact.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention herein is a flooring construction and, more
particularly, a prefabricated flooring construction consisting of
the wear layer surface and subfloor.
2. Description of the Prior Art
Broadly, the idea of a prefabricated construction material is
suggested in U.S. Pat. No. 3,077,059. Herein a flexible backing is
provided with a brick veneer. This assembly is delivered to the
construction site in a roll and then unrolled and placed on the
side of the building.
U.S. Pat. No. 2,508,128 discloses a structure for providing curved
surface walls, etc. Here a slat-like structure is fastened to the
back of a flexible board. The slat-like structure provides support
for the flexible board when it is bent into a curvilineal surface.
The slat-like structure is spaced to permit the forming of the
curvilineal surface.
Finally, NASA has developed a portable flooring surface for use on
surfaces to which a temporary flooring may be provided. The
temporary flooring is composed of a plastic foam plank structure
with a plurality of the foam planks being held together by webbing.
The structure is basically a portable slat-type flooring.
The object herein is to provide a flooring for commercial use
wherein a conventional resilient flooring or carpeting is factory
assembled to a subfloor structure composed of a plurality of slats.
This can then be rolled up in the factory and delivered to the job
site. There the subfloor and finished flooring are laid in one
operation.
SUMMARY OF THE INVENTION
The flooring herein is fabricated by placing either resilient or
carpeting material on thin slats of hardboard or other material.
The flooring material has the hardboard tightly bonded to the back
side or nonfinished surface of the flooring. The thin slats of
hardboard are adjacent and abutting each other when the flooring is
placed in a single plane, but the individual pieces or slats of
hardboard are not adhesively fastened together so that the
combination structure may be rolled up. The slatted hardboard with
the flooring can then later be fastened to a smooth subfloor or a
wood joist structure by the use of an adhesive. Consequently, both
the finished flooring and the subfloor are delivered to the
building site as a unitary structure to be installed at one
time.
BRIEF DESCRIPTION OF THE DRAWING
FIG. I is a cross-sectional view of the prefabricated floor in
position; and
FIG. II is a cross-sectional view of the prefabricated floor in its
rolled form.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The prefabricated floor 2, as shown in FIG. I, is composed of a
decorative flooring 4 and a subfloor structure 6. The decorative
flooring 4 can be either a resilient type flooring often referred
to as hard surface flooring or it may be carpeting. In the
embodiment shown in FIG. I, the flooring 4 is composed of a wear
layer surface 8 and a foam backing surface 10 similar to that shown
in assignee's U.S. Pat. No. 3,360,422. The subfloor 6 is composed
of a hardboard underlayment material which is cut into slat-type
form. Obviously, the slat material could be made of vinyls or other
man-made products.
The flooring 4 is adhesively bonded to the one side 12 of the slat
structure of the subfloor 6. The individual slats 14 are not
adhesively secured to adjacent slats. The individual slats are of a
thickness approximately equal to that of a conventional subfloor
material, that is, approximately three-fourth inch. The widths of
the slats may vary from 3/4 inch to about 21/2 inches. This permits
a structure which may be readily rolled up. Where two pieces of
slat material join themselves, there could be flat abutting
surfaces or you could have a groove in one board with a slight
tongue in the other. This is shown in FIG. I wherein the groove is
element 16 and the tongue is element 18.
Referring now to FIG. II, there is shown the prefabricated floor in
its rolled-up state. In FIG. I the prefabricated flooring is shown
in its installed position over a conventional support structure 20.
This could be a concrete slab structure to which the slat-type
subfloor 6 was adhesively secured or element 20 could be a
rafter-type floor structure wherein the individual slats 14 span
the space between a series of rafters. In FIG. II the flooring 4 is
sufficiently flexible that it may be bent into a large size roll.
The center core could be 10 to 12 inches in diameter. The subfloor
6 which is composed of a plurality of individual slats is
adhesively bound to the back side of the flooring. By not having
the adjacent edges of the individual slats bonded to each other,
they can separate sufficiently to permit the prefabricated floor to
be rolled up into a roll structure. When the flooring is rolled up,
a spacing 22 will exist between the individual slats, but the
individual slats will still be adjacent each other at the point 24
where two adjacent slats are bonded to the flooring 4.
The prefabricated floor will be fabricated in the factory by having
the subfloor slat elements fastened to the back side of the
flooring 4. This structure would then be rolled up and delivered to
the job site as a roll. A conventional support structure such as
the rafters of a floor or a concrete subfloor for a slab-type
construction will be in position, and the roll of prefabricated
flooring 2 will be unrolled in position over the conventional
support structure. Glue would be utilized in many cases to fasten
the lower side of the subfloor to the underlying support structure.
This would eliminate the need for laying the subfloor as a separate
operation from the laying of the actual finished flooring.
