Description
BACKGROUND OF THE INVENTION
1. Field of Invention
The present invention relates to a portable floor covering mat that protects floor surfaces from scratches and stains that can occur, for example, during appliance movement and repair.
2. Description of the Related Art
Heavy appliances, such as refrigerators and dishwashers, are occasionally moved outwardly from walls to make repairs and/or for cleaning. However, movement of these large appliances often results in unsightly scratches and marks on floor surfaces; such as linoleum, tile and hardwood. In addition, oil, grease or other materials can spill during appliance movement and repair, potentially staining floor surfaces.
Surprisingly few floor surface protectors have been developed to protect the floor surfaces when moving heavy appliances outwardly from a wall. It has been proposed to place protective strips under the feet or legs of the appliance. One such product, marketed as Glide Guard™ Floor Protectors, includes two narrow strips to be placed under the legs or wheels of the appliance at the time of installation of the appliance. When the appliance is to be moved, additional strips are attached to extend the protector forward from the front of the appliance. Once the strips are in place, the user pulls the appliance forward and away from the wall along these strips. Implementing prior known protectors like the Glide Guard™ Floor Protectors requires an owner to have sufficient foresight to place strips under the feet of the appliance at he time of installation in order to take advantage of these protectors in the future. otherwise the consumer must align the strips with the feet of the appliance and attempt to move/lift the appliance on to the strips.
In either case, pulling an appliance away from the wall often involves rocking he appliance side-to-side. The narrow width of products like the Glide Guard™ floor Protectors, provides little leeway for sideward movement of the appliance. arrow strips also do not protect the floor surface from spills or leaks that occasionally occur during repairs. Moreover such products are not robust for commercial use nor readily transportable. Thus, there remains a need for a portable structure that protects floor surfaces from scratches and spills during appliance movement and repair.
SUMMARY OF THE INVENTION
The main objective of the floor covering mat of the invention is to provide protection to floor surfaces from scratches and spills during appliance movement and repair.
An additional objective of this invention is to provide a floor covering mat that does not require prior installation of parts and that is readily portable to any location for immediate use.
A further objective of this invention is to provide a floor covering mat that may be easily cleaned after use.
The foregoing and other objects of the present invention are realized by providing a floor covering mat defined by first and second panels interconnected with a hinge so that the mat can be extended for disposition in front of an appliance to be serviced or folded for storage and transport. At least one side of each panel has a thickness transition section, such as a bevel, to facilitate sliding or rolling movement of the appliance onto the mat. Moreover, the panels are hingedly connected so that the thickness transition sections thereof form a substantially continuous longitudinal edge of the mat, to accommodate the full width of the appliance. When the floor covering mat is in an open, ready to use position, one surface of each panel is in substantial contact with the floor. Therefore, the hinge structure is preferably flush with or recessed from the floor contacting surface.
In accordance with a further feature of the invention, the ends of the panels remote from the hinge structure are provided with a handle structure to facilitate lifting and transport of the mat in its folded disposition.
Other objects, features, and characteristics of the present invention, as well as the methods of operation and functions of the related elements of structure, and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures.

DETAILED DESCRIPTION OF THE INVENTION
A floor covering mat
100
provided in accordance with the present invention is illustrated by way of example in
FIG. 1
, disposed in its extended configuration, ready to underlay an appliance
102
to be displaced, to protect floor surfaces
104
from scratches and spills that can occur during appliance
102
movement and repair.
For convenience and ease of description of the apparatus, directional terminology; such as length and width will be used. With reference to the illustrated embodiment, length will be used to refer to the dimension that extends parallel to the edge disposed in facing relation to the legs/wheels
106
of the appliance
102
. Width refers to the dimension that extends perpendicular to the length. Use of these descriptions are not intended to limit the invention in any way.
As noted above, mat
100
is adapted to protect floor surfaces
104
, such as hardwood, tile and linoleum, from marks, scratches and stains which can occur when sliding a heavy appliance
102
, such as a refrigerator or dishwasher, away from a wall for servicing. Accordingly, mat
100
has a length of a size to receive the full width of refrigerators, dishwashers, and the like that it is intended to receive. On the other hand the mat
100
is adapted to be readily transported from service location to service location and stored between uses. Thus, the mat provided in accordance with the invention can be extended for use and dimensionally reduced for storage and transport.
In the illustrated embodiment, the mat is defined by at least two square or rectangular panels
110
that are interconnected by a hinge structure
120
. The panels
110
are each sized so that when the mat is in its extended, full length disposition, with the panels disposed end to end, the mat will receive the full width of the appliance to be serviced and, preferably, accommodate any modest lateral displacement of the appliance during the appliance pull out process. Furthermore, the panels are each sized so that the extended mat will receive at least about 50 % of the full depth of the appliance to be serviced. This dimensional characteristic was determined as a result of the limited amount of floor space the mat can maintain without being too large in confining areas, i.e. apartments, thereby making it more universal in design and use. Thus, in accordance with the presently preferred embodiment, when the appliance must be removed completely from the confining wall area, it is simply slid onto the working depth of the mat, as discussed in greater detail below, and then both the mat and the appliance (when tilted) are moved out from the wall together on the low friction surface of the mat bottom.
In the illustrated, presently preferred embodiment, the mat is composed of two panels for ease of manufacture and handling. However, if the size of the panels
110
required to accommodate a particular appliance
102
is such that even folded, providing two panels is not deemed readily portable or stowable, the mat
100
may be composed of multiple panels
110
of a smaller size.
The material selected for the panels
110
should preferably be a low friction material. Providing a low friction material facilitates sliding movement of the heavy appliance
102
from the floor surface
104
to the protective floor mat
100
.
As the mat
100
is intended for repeated use, the material should also demonstrate resilience and low wear. Using a resilient material for panels
110
will reduce the likelihood that the panels will crack or chip under load, or themselves mar the floor. Moreover, advantageously, resilient panels
110
will maintain their shape and can be flexed as necessary or desirable during transport and use. Providing a low wear material ensures that the panels
110
are not easily worn down or rutted by repeated use.
During the course of appliance
102
movement and repairs, oil, grease and others may spill. Thus, the material selected for the panels should be non-absorptive, to simplify the cleanup of the mat
100
. Finally, as the mat
100
intended to be portable, a light weight material is preferred.
An exemplary materials exhibiting the above properties are Ultra High Molecular Weight Polyethylene and High Density Polyethylene. For preliminary manufacturing, i.e. machined, the former has been used. However, higher volume production will likely be injection molded using the latter, since Ultra High Molecular Weight Polyethylene can not be injection molded. Other materials exhibiting the above noted characteristics and suitably adapted to the contemplated manufacturing process may be utilized in the alternative.
Each panel
110
is formed as a thin, flat panel with an upper surface
112
and a lower surface
114
, as shown in FIG.
2
. The thickness of the panels
110
should be sufficient to support the weight of the appliance
102
without cracking. At the same time, the thickness of the panels
110
should not render the mat
100
too heavy for transport, or cost-prohibitive to make.
At least one longitudinal edge of each panel
110
is configured to have a thickness transition section
116
, as shown in FIG.
1
. Inclusion of a thickness transition section
116
along a side edge of the panel
110
allows the legs/wheels
106
of the appliance
102
to be shifted with relative ease from the floor surface
104
to the mat
100
without lifting the appliance
102
, as shown in FIG.
2
. In the illustrated, presently preferred embodiment the thickness transition section
116
is a beveled edge that extends downwardly and outwardly at a modest angle from the upper surface
112
to the lower surface
114
. In an exemplary embodiment, the angle of the beveled edge
116
is between about 5 degrees and about 30 degrees, but preferably about 15 degrees. Note that in the illustrated embodiment the thickness transition section
116
extends the entire face length of the mat. This best serves the removal of an appliance when it is positioned directly up against a wall. Although as presently proposed the thickness transition sections are smooth surfaced beveled edges, other types of thickness transition sections, such as stepped edges having a series of discrete yet minute steps may be provided.
As noted above, in the presently preferred embodiment, the lower surface of the mat is a low friction surface, so that it is possible to slide the appliance and mat together once the appliance is positioned on the top working surface of the mat, over the surface of the floor with relative ease. Nevertheless, it may be desired, in some environments or applications of the inventive mat to provide sections
124
of the lower surface of the panels
110
that are textured or have friction or grip pads applied or molded thereto to minimize movement of the mat
100
relative to the floor surface
104
, particularly when the user is displacing the appliance
102
on to the mat
100
.
The panels
110
are interconnected by a hinge structure
120
disposed along adjacent end edges of the panels
110
. To avoid marring the floor and to present a mat lower surface that is substantially flush with the floor, the hinge structure is preferably flush with or recessed relative to the lower surface
114
. Although not critical, the hinge structure is preferably flush with or recessed relative to the upper surface as well so that the hinge does not present an obstacle, and to avoid floor damage should the mat be placed on the floor upside down.
In the illustrated, presently preferred embodiment, the hinge structure is a living hinge, as such a hinge is well suited to the proposed material for the mat, is cost effective and easy to form, and lays flush with one surface. In the illustrated embodiment, the living hinge is defined so that the mat folds with the lower, floor contacting surfaces facing each other. As such dust and dirt that might be present on the floor and transferred to the mat will be less likely to dirty other surfaces or clothing.
The hinge
120
connects the panels
110
in a configuration that aligns the beveled edges of panels
110
so that the beveled edges define a substantially continuous edge of the mat
100
. In the illustrated embodiment, both longitudinal edges of the mat
100
are beveled so that either longitudinal edge may be placed in front of the appliance to be moved.
As shown in
FIG. 5
, the hinge
120
allows the panels
110
to fold along the hinge
120
into a folded position, wherein, depending on the orientation of the hinge, either the upper surfaces
112
or lower surfaces
114
of the panels
110
are in close proximity to each other. The folded position places the mat
100
in a compact form for easy transport and storage. If there are more than two panels
110
forming the mat
100
, the hinges
120
may allow the panels
110
to be fold in an accordion style to form a compact portable structure.
To facilitate the transport of the mat
100
, handles
126
and/or fasteners
128
may be provided. Handles
126
allow the mat
100
to be comfortably transported in a folded position. The handles
126
may be formed as a part of the mat
100
or attached as a separate component for transport. Thus, handles
126
may be formed near an edge of each panel
110
as an aperture of a size sufficient to accommodate an adult hand, as shown in FIG.
1
. Length may be added to the end of each panel
110
for the sole purpose of defining handles
126
in to the panels
110
. The added length may consist of a thicker material to provide a more comfortable grip to the handles
126
, as shown in
FIGS. 4 and 5
. In the alternative handles
126
may also be simply formed from a strap configured to transport the mat
100
. If desired, holes may be formed in the panels
110
to provide a place to secure the handles to the mat
100
. Although in the illustrated embodiment, the handles are adapted to be provided at the ends of the mat, it is to be understood that in the alternative, although less desirably, handles may be defined or attached along the side edges of the mat.
Fasteners
128
, which are schematically depicted as lines through holes
130
, may also be included to improve the portability and storability of the mat
100
by maintaining its compact, folded position. Fasteners
128
may be either integrated into the mat
100
or formed as a separate piece only to be attached at times of transport and storage. Forms of integrated fasteners
128
include magnets mounted or molded to the panel end portions so that they are in close proximity to each other when the mat
100
is in a folded position. Alternate fasteners
128
include U-shaped clips, threaded shafts and wing nuts, ties, straps with velcro or snaps, and the like. Holes
130
may be formed in the panels
110
to secure the position of the fasteners
128
to the mat
100
.
The design of the mat
100
allows the present invention to be simply implemented. As shown in
FIG. 2
, a user places a beveled longitudinal edge of the mat
100
adjacent the front legs/wheels
106
of the appliance
102
. Once the mat
100
is in place, the user guides the appliance
102
by generally pulling and sliding the appliance
102
onto the mat
100
. When the repairs are complete, the user returns the appliance
102
to its original position by pushing and sliding the appliance
102
down the beveled edge
116
to the floor surface
104
. Following use, the mat
100
may be readily cleaned if desired, folded, and fastened, if desired. After folding, the mat
100
may be transported and/or stored for future use in its folded position.
While the invention described in connection with what is presently considered to be the more practical and preferred embodiment, it is not to be limited to the disclosed embodiment, but on the contrary is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
