Weighted, Foldable, Pleated Tablecloth Apparatus and Method
Abstract
A cover such as a tablecloth is provided with a system of
weights proximate the perimeter thereof in order to resist the
dislodgement of the tablecloth from the table by the presence of
wind. Containment for the weights is selected to have a length and
diameter suitable for installation with a periodicity providing
periodic gaps. The gaps assist in folding the cover for storage, as
well as providing natural breakpoints for pleating, so it will
drape more naturally from the edges of corners of the supporting
equipment or table covered by it.

Description
BACKGROUND
[0001] 1. The Field of the Invention
[0002] This invention relates to tablecloths and mechanisms for
securing tablecloths in outdoor environments exposed to wind.
[0003] 2. The Background Art
[0004] Covers for equipment take on many forms. A good example is a
tablecloth used in outdoor environments such as camping,
picnicking, parties, entertainment, and the like. Outdoor
environments are frequently exposed to some degree of breeze or
wind. It is not uncommon for wind to not only put the table cover
in disarray but may actually flip it over, spilling and otherwise
adversely affecting the contents held by the table. For example,
drinks may be tipped over with a comparatively modest force as a
tablecloth is caught up by winds and pushed across a table.
[0005] It would be an advance in the art to develop a system and
method to secure tablecloths against the affects of breezes and
wind while still providing decorative themes desired and a ready
susceptibility to be easily folded up and stored.
BRIEF SUMMARY OF THE INVENTION
[0006] In accordance with the foregoing, an apparatus and method in
accordance with the invention provide a system of weighting having
periodic gaps to provide the aesthetic appeal and proper
functioning of folds and pleats that naturally should occur in the
manner of draping a cover, such as a tablecloth, over an item of
equipment, such as a supporting table. Hereinafter, whenever the
term "tablecloth" is used, it is used both to recite a tablecloth
specifically, and as an example of any general cover for equipment
maintained outdoors.
[0007] For example, indoors, a fabric or plastic dust cover or
protective cover may be draped over an article of equipment. In one
example, a cloth table covering will drape down over the edge of a
table. In accordance with the invention, a system of weights
provides periodic gaps in the weighting in order to support
pleating of the cover as it drapes from the edge, and particularly
the corners, of a covered table.
[0008] Meanwhile, the weighting system is also provided with
periodic gaps suitable for folding. Stretching of materials,
bursting of containers, distortion of the weights, containment
systems, or the cover itself (e.g., tablecloth) is not required in
order to conveniently fold up the tablecloth for storage.
Hereinafter, the tablecloth illustrated represents one embodiment
of a cover, used by way of a specific embodiment, and as an example
generally. However, in general, protective covers in accordance
with the invention may be formed as a flat sheet to drape over
equipment, or may be sewn to be shaped more like the actual
perimeter of equipment covered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0048] It will be readily understood that the components of the
present invention, as generally described and illustrated in the
drawings herein, could be arranged and designed in a wide variety
of different configurations. Thus, the following more detailed
description of the embodiments of the system and method of the
present invention, as represented in the drawings, is not intended
to limit the scope of the invention, as claimed, but is merely
representative of various embodiments of the invention. The
illustrated embodiments of the invention will be best understood by
reference to the drawings, wherein like parts are designated by
like numerals throughout.
[0049] Referring to FIG. 1, while referring generally to FIGS.
1-32, a cover apparatus 10 (e.g., tablecloth 10, furniture cover
10, barbecue cover 10, machinery cover 10, or the like) may be
formed to have a cover portion 12 surrounded by a hem portion 14.
The hem portion 14 is sometimes referred to simply as the hem 14.
In general, the hem portion 14 or hem 14 is created by the hem
stitch 16 securing a loop portion 14 of the material back to itself
at the edge of the cover portion 12. Hereinafter, the term
"tablecloth 10" is used by way of both a specific example and as a
general representation for all the types of covers that may benefit
from the invention.
[0050] In certain designs in accordance with the invention, a trim
portion 18 may be added. The cover portion 12 may have no pattern
at all, may have any color at all, may include a particular
selection of a pattern, or the like. Meanwhile, the trim portion 18
may likewise have a pattern, no pattern, a color or no color, and
may or may not have the selected pattern or no pattern of the cover
portion 12. Thus, in general, various artistic or graphic elements
may be added to the cover portion 12, the trim portion 18, to both,
or to neither.
[0051] Meanwhile, the color selection for the cover portion 12, and
the trim portion 18 may be selected to be complementary, analogous,
monochromatic, identical, contrasting, or the like. Thus, in
general, the color portion 12 may be a solid color including white
or black, while the trim portion 18 may be a solid color including
white or black, and either the cover portion 12 or the trim portion
18 may be patterned to have any particular graphic design desired.
For example, stars, flowers, gingham, calico, checkered, plaid, or
the like may be selected in any color scheme to be a pattern
imposed on the cover portion 12, the trim portion 18, both thereof,
or neither thereof.
[0052] Within the trim portion 18, and particularly within the hem
14, weighting materials may be captured, such as by being sewn in.
Typically, the weighted materials may be granular, pelletized, or
solid. In certain embodiments, the weighting materials may actually
be liquids, slurries, or the like. The weighting materials may be
sealed within containment suitable to resist puncture, resist
bursting, and otherwise tolerate the vagaries of abuse, wear,
weather, and other circumstances. The weighting materials may be
installed within the hem 14 to create certain gaps 20 or flat
portions 20 between filled portions 22. By providing the gaps 20
along the perimeter of the trim portion 18, the tablecloth 10 may
be created to present folds 24. The folds may appear to occur
naturally at the gaps 20 where no fill materials are located. In
the gap regions, in certain embodiments, it is possible to simply
provide for either no fill material, or very sparse amounts of fill
material in order to accommodate folding, bending, pleating, or the
like.
[0053] For example, when a tablecloth 10 is draped over a table, an
object 10 that was formed to be entirely flat now must drape down
of an edge of the table where it now contains excess sheet
material. With cloth, one is accustomed to the natural draping of a
tablecloth, naturally pleating at the corners in response to the
excess material at the corners.
[0054] By suitable selection of the length of the gaps 20 and the
filled portion 22 along the perimeter of the hem 14, one may
promote one or several locations of pleating at the gaps 20.
Accordingly, the tablecloth 10 will drape in folds 24, and pleats
26 therebetween. Likewise, each of the gaps, provides a location at
which the tablecloth 10 may fold or be folded easily. Since the hem
14 at a gap 20 may be a mere two layers thick, the front portion
and the back portion of the hem 14, the tablecloth may be folded at
those locations.
[0055] The gaps 20 and filled portions 22 may be sized and combined
to provide suitable numbers of folds 24 and pleats 26 to provide an
aesthetically pleasing appearance. For example, in certain
embodiments, the filled portions 22 may extend only a comparatively
short length, for example, about three inches each. Meanwhile, in
other embodiments, the filled portion 22 may extend 6 inches, 1
foot, or the like. Typically, distances greater than 1 foot for the
lengths of the filled portions 22 may be problematic in providing
for suitable, simple, straightforward folding and storage.
[0056] In some embodiments, the cover portion 12 and the trim
portion 18 may be separated only by the patterns printed thereon.
In other embodiments different materials preprinted with unique
patterns may be used for the cover portion 12 and the trim portion
18. For example, in the illustrated embodiment, seams 28 may be
used to secure the cover portion within the trim portion 18.
Likewise, to manufacture the trim portion 18 from lengths of a
material, the seams 28 may also be used to form diagonals, gussets,
or the like at corners and other locations, in order to accommodate
the optimal use of materials without unnecessary waste.
[0057] For example, it makes more economic sense to form the trim
portion 18 from a strip of material than it does to cut it from a
large, single piece. On the other hand, in certain embodiments, a
cover portion 12 may be made of one material, while the central or
cover portion 12 of another tablecloth 10 is cut out from its trim
portion 18. Thus the waste from each trim portion 18 could be used
as a cover portion 12 on another tablecloth. Nevertheless, in the
illustrated embodiment, the seams 28 extend along the diagonals and
corners in order to join the strips forming the trim portion
18.
[0058] Referring to FIGS. 1-21, one may see that a tablecloth 10
may include a cover portion 12 that may extend all the way to the
hem 14. Alternatively, as illustrated, the hem portion 14 may
actually be at the edge of a trim portion 18 secured by seams 28 to
the cover portion 12, that portion 12 central to the tablecloth 10
and located on the top of the table.
[0059] In certain embodiments, the trim portion 18 may extend onto
the top of the table. Nevertheless, in the illustrated embodiment,
cleaning off the cover portion 12 may be easier if it is formed as
a single, smooth sheet. Maintenance and use may be better served by
forming the trim portion 18 only in that part of the tablecloth 10
that will drape below the edge of the table covered.
[0060] In general, the hem 14 or hem portion 14 may be formed by a
hem stitch 16 to create various pockets 22 or filled portions 22,
separated by gaps 20 or flat portions 20 therebetween about the
perimeter. The gaps 20 or flat portions 20 provide for folds 24.
The folds 24 are suitable for folding the tablecloth 10 for storage
or to allow the tablecloth 10 to drape appropriately in a system of
folds 24 and pleats 26 resulting from the excess perimeter
length.
[0061] Referring to FIGS. 8-14, while continuing to refer generally
to FIGS. 1-32, the aspect ratio of length to width of the
tablecloth 10 may be determined according to a table to be covered.
For example, picnic tables, banquet tables, and the like have an
aspect ratio of length to width greater than unity. On the other
hand, circular tables, square tables such as card tables, and the
like may have an aspect ratio of one when comparing length to
width.
[0062] Referring to FIGS. 15-21, while continuing to refer
generally to FIGS. 1-32, a circular corner or a radiused corner may
be added to any particular table cloth 10 in order to provide
simpler manufacturing, aesthetic appeal, or the like. For example,
in the absence of corners, certain additional requirements are
added, but certain requirements are eliminated. For example, the
hem stitch 16 may run continuously, rather than terminating at a
corner joint. Meanwhile, such an embodiment may provide a more even
length near the corners of a table.
[0063] Referring to FIGS. 22-23, a tablecloth 10 in accordance with
the invention may include an intermediate strip 30. The
intermediate strip may be designed to display a solid color,
including black or white, or may be provided with another pattern.
For example, in certain embodiments, the cover portion 12 may be
patterned after a calico or other pattern, while the trim portion
18 is in a distinct and different pattern, for example, a gingham
pattern. Meanwhile, intermediate portion 30 or the strip 30 may be
of a suitable pattern and color, such as, for example, a solid
color providing an interface 30 between the cover portion 12 and
the trim portion 18.
[0064] Referring to FIGS. 24-25 in particular, and all Figures
generally, a substantially rectangular or square embodiment of a
tablecloth 10 in accordance with the invention may include either
sharp or rounded corners and may or may not include intermediate
strip 30 between the cover portion 12 and the trim portion 18.
[0065] Referring to FIGS. 26-29 in particular, and all Figures
generally, in certain embodiments of an apparatus 10 in accordance
with the invention, a tablecloth 10 may be designed in a circular
pattern. The seams 28 may be used to match the trim portion 18 in a
shape to surround the cover portion 12. Meanwhile, an optional
intermediate strip 30 may be included therebetween.
[0066] As can be seen, a circular configuration may include
periodic gap portions 20 between the filled portions 22 in order to
provide an aesthetically pleasing system of folds 24 and pleats 26.
In a circular embodiment, shorter lengths for the filled portions
22 may be appropriate in order to provide a more aesthetic
appearance for a circular tablecloth 10.
[0067] For example, in rectangular tablecloths 10, the tablecloth
drapes along each edge as a single sheet. By contrast, near each
corner, the tablecloth must drape in a combination of folds 24 and
pleats 26 to accommodate the mismatch in length between the table
corner and the portion of the tablecloth 10 near its own
corner.
[0068] By comparison, a circular tablecloth virtually always has a
diameter mismatch, leaving too much material relative to the
perimeter of the table. Accordingly, a continuous system of folds
24 and pleats 26 will typically occur with a cloth tablecloth over
a table. Similarly, the lengths of the filled portions 22 may be
formed to be of a comparatively shorter length, typically between
one and six inches such as, for example, about 3 inches. These
shorter filled portions 22 promote a more continuous, distributed,
aesthetic system of folds 24 and pleats 26 of a circular tablecloth
when in use.
[0069] Referring to FIGS. 30-32 in particular, and all Figures
generally, a filled portion 22 of the hem 14 of a tablecloth 10 may
have a diameter 32 of from about 1/4 inch to about 1 inch.
Typically, a diameter 32 of about 1/2 inch to 3/4 inch provides a
suitable weight and size. Typically, the length 34 of the filled
portion 22 may be selected as described above in order to
accommodate a system of folds 24 and pleats 26 aesthetically
pleasing under the circumstances.
[0070] Likewise, the length 36 of the flat portion 20 or gap 20 may
be suitably sized. In one embodiment, the length 36 may be at least
a whole diameter 32 in order to accommodate each half of a diameter
of adjacent filled portions 22. In other embodiments, the length 36
may be at least up to 2 diameters 32 of the filled portion 22 thus,
when folded for storage, the tablecloth may have sufficient slack
along the length 36 to accommodate an easily folded pair of filled
portions 22 adjacent to one another.
[0071] In certain embodiments, the fill material may be selected
from synthetic or natural materials. For example, small gravel such
as is used in aquariums is a suitable fill material and competitive
in cost. Likewise, sand serves well as a suitable fill material 38.
In other embodiments, pellets, granules, shot, and the like may be
used. Steel, lead, plastic, and the like may all be suitable fill
materials 38. In certain embodiments, the additional weight of
steel or lead shot may be easily distributed down to a single piece
at a time--shot may also provide a smaller diameter 32 for
comparable weight. Thus, in general, a fill material 38 selected
may be of any suitable configuration including liquids, solids, and
particularly any granular solid.
[0072] On the other hand, the use of sand as a natural fill
material 38 may provide trade offs. Sand may require a larger
diameter 32 for comparable weight. However, sand is easily
obtained, easily installed, is cost effective, and may be easily
disposed of when a tablecloth 10 is worn out. Similarly, other
natural materials such as gravel may likewise serve.
[0073] Typically, stitching 40 may be formed in any manner. The
illustrated hem stitch 16 in FIG. 30 is a zig-zag stitch. In other
embodiments, and as illustrated elsewhere, the hem stitch 16 may be
a straight stitch or otherwise. Also, the stitching 40 may be heat
sealed, glued, or sewn with thread. Nevertheless, the stitching 40
may be the same as the style and material of the hem stitch 16, or
different therefrom. Regardless, the stitching 40 may typically be
formed as a single stitch between adjacent filled portions 22, or
as two corresponding stitchings 40 established in a length 36 of
the gap portion 20.
[0074] Referring to FIG. 31, the material of the tablecloth 10 may
be selected to be of a polymer, such as plastics and the like, a
natural material, or the like. Thus, the material of the tablecloth
10 may need no reinforcement 42. In other embodiments, oil cloth is
a suitable material. Oil cloth may be formed to have a main plastic
sheet backed by some reinforcement 42, such as an included fiber or
a cloth bonded thereto.
[0075] Referring to FIG. 32, in one embodiment, the filled portion
22 may be filled by a bag 50 containing a fill material 38. The bag
50 may be formed of any suitable material. For example, if the fill
material 38 is a granular or a pelletized material, the bag 50 may
be formed of fabric, woven, or nonwoven, or the like, including
natural, porous materials. In other embodiments, the bag 50 may be
formed of a flexible or stiff, solid plastic film, sheet, or tube,
in order to seal the bag 50.
[0076] The seal 52 may be formed in any suitable manner. For
example, a fastener, a fold, a grip, glue, and the like may be
considered as a seal 52. In other embodiments, heat may seal a bag
50 formed of a polymer film. The bags 50 may typically be of a
single length 54. In another embodiment, within a single tablecloth
10, the bags 50 may be formed at separate and distinct lengths 54
in order to accommodate, for example, longer expanses of long edges
of the table, with shorter systems of folds 24, and pleats 26 near
corners. In other embodiments, the lengths 54 may all be the same
within a tablecloth. Accordingly, the design and manufacturing may
be balanced according to what is most advantageous and
aesthetic.
[0077] The present invention may be embodied in other specific
forms without departing from its spirit or essential
characteristics. The described embodiments are to be considered in
all respects only as illustrative, and not restrictive. The scope
of the invention is, therefore, indicated by the appended claims,
rather than by the foregoing description. All changes which come
within the meaning and range of equivalency of the claims are to be
embraced within their scope.
