[0001] This invention relates to the installation of molding with a divider track. This
installation method is particularly useful in the installation of laminate flooring.
[0002] Commercially available laminate flooring generally includes a wear surface glued
to a substrate. The wear surface generally is high-wear resistant decorative laminate.
The substrate generally is fiber board or particle board. Each piece of laminate flooring
generally has a groove along one end and one side suitable for joining with a tongue
along one side or end of an adjacent piece of laminate flooring. Laminate flooring
is commercially installed over a pad.
[0003] Aluminium divider tracks are commercially used for the installation of flexible molding,
such as vinyl molding. This includes the installation of expansion and transition
molding, end caps and reducer strips. Divider tracks are affixed to a floor and a
rib on the back of flexible molding is interlocked between a pair of flanges extending
from the front of the divider track. Serrations extending along the rib and the interior
surfaces of the flanges interlock for resisting the removal of the rib from the flanges.
Molding can be installed by interconnecting it with a divider track without penetrating
its decorative front surface with fastening means or otherwise blemishing it.
[0004] There is a need in the installation of molding for securely affixing the molding
without blemishing its decorative front surface. In the installation of laminate flooring,
there is a need for molding covered with laminate that matches the pattern of the
laminate flooring and wood molding that co-ordinates with the pattern on the laminate
flooring. There is a need for a method of installing laminate covered and wood molding
that does not blemish its decorative front surface.
[0005] It has now been discovered that a divider track can be used for installing molding.
A divider track having a pair of spaced apart flanges extending at a right angle from
the front surface of the divider track is affixed to a surface. Kerfs cut on the back
surface of molding are positioned over spaced apart flanges extending at a right angle
from the front surface of the divider track. Pressure is applied on the front surface
of the molding for seating the molding on the divider track. Serrations extending
along the interior upper surfaces of the flanges aid in interlocking with kerfs cut
on the back surface of the molding.
[0006] Molding for laminate flooring has a decorative front surface and planar rear surface.
The planar rear surface has a planar central portion and a planar flange portion.
The flange portion intersects the decorative front face of the molding at its edge.
The flange portion also intersects a shoulder that extends from the planar central
portion to the planar flange portion. The shoulder extend at a right angle from the
planar central and flange portion of the molding.
[0007] A pair of kerfs are cut in the planar central portion of the planar rear surface
and extend along the molding for joining the molding in a friction fit on a pair of
spaced apart flanges extending at a right angle from the front surface of a divider
track. The depth of the kerf cuts is about the thickness of laminate flooring and
the distance from the planar central portion to the planar flange portion is less
than the thickness of laminate flooring whereby the planar flange portion of the molding
will be seated on the planar front surface of the laminate flooring when the molding
is seated on a divider track. The kerfs have side walls that extend at right angles
from the planar thousandths of an inch less than the widths of flanges extending from
the front of a central portion of the back surface of the molding. The kerfs have
widths of about two divider track on which the molding is to be seated.
[0008] The molding can be wood or laminate wrapped particleboard, wood or extruded plastic.
[0009] Shown on the figure is the insulation of an expansion joint between sections of laminate
flooring with kerfs cut in a planar back surface of molding for interconnection with
flanges extending at right angles from the front surface of a divider track.
[0010] The use of kerfs (16) cut in a planar back surface (15) of molding (1) for installing
the expansion molding for laminate flooring is shown on the figure. Kerfs (16) cut
in the planar back of expansion molding provide a friction fit between the molding
and flanges (25) on an aluminium divider track (2) for securely connecting the molding
and divider track.
[0011] The expansion molding shown on the figure is laminate wrapped fibreboard. Laminate
can be bonded to other substrates, such as particle board, wood or extruded plastic
for making a molding. Molding can also be wood that co-ordinates with the laminate
flooring pattern. This expansion molding has kerfs cut into its back side. These kerfs
have sidewalls that extend at right angles from a planar back surface of the expansion
molding, these kerfs having widths for providing a friction fit with flanges on a
divider track. A kerf that is about two thousandths of an inch less in width than
the width of flanges extending from the front of a divider track has been found suitable
for providing a secure, friction fit between the molding and the divider track. It
has also been found that the planar back surface of the molding should not contact
the front surface of the divider track when the molding is seated on the divider track.
[0012] The molding has a decorative front surface (11) and a planar rear surface (15). The
planar rear surface (15) has a planar central portion (17) and at least one planar
flange portion (18). The kerfs (16) are cut in the planar central portion (17). The
planar rear surface (15) of expansion molding has two planar flange portions (18).
These flange portions (18) intersect the decorative front face (11) of the transition
molding at the edge of the molding (1) and shoulders (19) that extend from the planar
central portion (17) to the planar flange portions (18). The shoulders (19) extend
at right angles from the planar central (17) and flange portions (18) of the transition
molding.
[0013] It has been found that the distance from the planar central portion (17) to the planar
flange portion (18) should be less than the thickness of laminate flooring. The kerfs
(16) should be cut to depth of about the thickness of laminate flooring. Thereby,
the planar flange portions (18) of the transition molding will be seated on the planar
front surfaces of the laminate flooring on both sides of the divider track when the
transition molding is seated on the divider track. Other molding, such as end cap
and reducer strip molding, will only have one planar flange portion for seating on
laminate flooring on one side of the divider track.
[0014] A pair of flanges (25) extend at right angles from the front planar surface (21)
of an elongated aluminum divider track (2), Figure. Serrations (26) extend along the
interior upper surfaces of the flanges (25). When the expansion molding is seated
on the divider track, the serrations aid in a friction fit of the expansion molding
on the divider track.
[0015] The divider track shown in the Figure illustrating this invention can be made by
extrusion molding metal, preferably aluminium, or rigid synthetic resin. The selection
of suitable materials, methods and equipment for extrusion molding is known to those
skilled in the art of making extruded molding.
[0016] While the illustrative embodiments of the invention have been described with particularity,
it will be understood that various other modifications will be apparent to and can
be readily made by those skilled in the art without departing from the spirit and
scope of the invention. Accordingly, it is not intended that the scope of the claims
