Description
Cover cloths, which include tarpaulins, drop cloths, blankets,
sheets, wrapping and the like, have many uses both inside and
outside various types of structures. A few of such pieces include
coverings for objects during painting, protection of various items
from adverse weather conditions, protection for stored items and
the like. All such coverings are sheet like material, and as such,
they are subject to being disarranged from their spread-out
covering position over the desired area by many different factors.
People, vehicles, wind and the like can cause a disarray of the
coverings so as to expose the covered objects.
It is, therefore, an object and advantage of the present invention
to provide a covering having at least two opposed, continuously
weighted edges which tend to hold the covering in a spread-out
position.
Another object of the invention is to provide an inexpensive and
simple means for holding a covering spread over any desired area
against disarrangement by wind or other extraneous forces.
Still another object and advantage of the invention is to provide a
covering which has attached weights providing self-contained
hold-down means.
Yet another object of the invention is to provide a rectangular
covering having four edges containing continuous flexible weight
material for securing such covering in a spreadout condition.
An additional object of the invention is to provide insulated
and/or heated rectangular covering having flexible weight means
continuously extending around the periphery of such covering for
securing the covering in spread-out position.
A further object of the invention is to provide a selfcontained
covering for securing the same over desired areas, but which is
sufficiently light for easy transportation and still provide a
secure covering over a desired area under adverse conditions.
These and other objects and advantages of the invention may be
readily ascertained by referring to the following description and
appended illustrations in which:
FIG. 1 is a perspective view of one form of the rectangular
covering according to the invention illustrating one form of
weighting means extending completely around the periphery of the
rectangular covering;
FIG. 2 is a cross-sectional view of the device of FIG. 1 taken
along section lines 2--2;
FIG. 3 is a modified form of a rectangular cover showing continuous
weighting on two opposed edges of the covering;
FIG. 4 is a cross-sectional view of a modified form of covering
providing an insulating covering for curing concrete and the
like;
FIG. 5 is a schematic perspective view of a rectangular covering
including a weighted flexible periphery and including heating wires
in the insulated body; and
FIG. 6 is a cross-sectional detail view of a modified form of
securing means for flexible weighting material along the edge of a
cover cloth.
In the device illustrated in FIGS. 1 and 2, a rectangular sheet
material cover 10 may be formed of any size and any desired
material. For example, the cover may be made from cloth of woven,
natural or synthetic fibers, may be of continuous sheet material
such as synthetic plastic film or the like, may be of metal covered
sheet material such as aluminum foil on canvas, or the like, or may
be of any desired flexible cloth-like material used for covering
any object. The sheet-like material may be made in any size and
generally is made rectangular for ease of manufacture and use.
Opposed edges 12 and 14 are folded back along themselves and are
sewn together to form a pocket or wide hem which extends along the
length of the cloth 10. In a similar manner, edges 16 and 18 are
folded back along themselves and are sewn to form an elongated
pocket along the edge of the cloth. As shown in FIG. 2, edge 12 is
folded back along itself and sewn by stitching 13 extending along
the edge and in the same manner, edge 14 is folded back along
itself and is stitched at 15, both forming an elongated pocket
along the edge. In a similar manner, the edges 16 and 18 are folded
and stitched to form an elongated pocket. The pocket at edge 12 is
filled with sand, shot, or other granular or particulate weighting
material 20 and the pocket at edge 14 is likewise filled with a
similar material 21. The weighting material 20 and 21 is preferably
granular so as to form a continuous weight which is flexible and
easy to handle. The pockets at edges 16 and 18 are similarly filled
with the particulate material. With the pockets sewn tight, the
cloth may be spread out and used to cover any desired item. The
weighted edge holds the cloth from disarray by wind, people, etc.
In a 12 ft. by 15 ft. canvas tarp, with the edges rolled back and
sewn, about 40 to 50 pounds of sand may be placed in the tubes
along the edges to provide weighting material for the canvas. If
desired, small separate bags of sand may be placed in the hem
formed by the turning back and stitching rather than filling the
tube with free sand. By the use of the small bags, the weighting
material may be made semi-permanent since a corner may be left open
for removal of the bags if desired.
The modification shown in FIG. 3 includes a rectangular cover 25
having opposed edges 26 and 27 turned back upon themselves and edge
26 has stitching 28 therealong to form a tube and edge 27 has
stitching 29 therealong to form a tube along that side. The ends 30
and 31 of the tube 26 may be closed after insertion of free sand,
shot or particulate material, or insertion of individual bags 28a
containing this material. Stitching 29a, across the tube 26, may be
provided to hold the bags or loose material in position. In a
similar manner, the tube 27 has its ends 32 and 33 closed after the
insertion of weighting material in the edge. The size of the cloth
25 is, of course, determined by the size of the object over which
it will be placed.
The modification of FIG. 4 utilizes an insulated cover 35 with
edges 36 and 37 folded back upon themselves and stitched to form
tubes. Weighting material 38, as described above, is placed in the
tube 36 and weighting material 39 is placed in the tube 37 to form
flexible edge weights for the insulated cloth 35. In a similar
manner, the edge 40 is folded back upon itself and stitched to
provide a tube for holding the weighting material for the
cover.
The modification of FIG. 5 includes a cover or insulating blanket
45 having edges 46, 47, 48 and 49 folded back along themselves and
sewn to form tubes in which weighting material is placed. The
insulated blanket 45 has included therein, electric heating coils
50 to provide heat for curing cement or the like, and a connection
51, illustrated as a two prong plug, is arranged to be connected to
an electrical source to provide current for the coils in the
blanket 45. The heated insulated blanket is useful for curing
concrete in cold weather where it is desirable to maintain the
temperature of the concrete above freezing at least for its initial
setting period.
The modification of FIG. 6 illustrates a cover 60 having a tube 61
extended along its edge filled with a weighting material 62. The
tube 61 extends along the length of an edge of the cover 60 and is
fastened by means of a plurality of snap fasteners 63 to snap
fasteners 64 secured in the edge of the cover. This provides a
semi-permanent means of affixing weighting tubes along all the
edges of the cover. Obviously, various types of fasteners may be
used to secure the tubes of weighting material along the cover
edges, and these would include zippers, Velcro fasteners, and the
like. Preferably, the tube should extend along the full edge of the
cover to prevent bulges in the edge which permits wind to enter
under the edges and disarray the spread-out cover.
The weighting materials should extend along the full edge of the
drop cloths or covers, and in the preferred form, the weighting
material extends along all peripheral edges as a continuous
flexible weight. This provides means for securing the edges of the
cloth to the supporting material, which may be the ground, floor,
etc. to prevent wind from coming under the edge of the cloth,
filling the same and blowing the cloth away or disarraying it from
its spread-out position. As pointed out above, 40 or 50 pounds of
sand are sufficient to weight a 12 .times. 15 ft. drop cloth, and
in similar manner, various weights may be used for different sizes
of cover cloth depending on the use for which it will be made. By
having the weighting material continuous and flexible, the weighted
edge conforms to the contours of the surface on which the cloth is
spread, thus providing a secure means for holding the cloth down
under adverse conditions.
Although a weighted, rectangular drop cloth or cover has been shown
and described in this specification, it is to be understood that
this shape is illustrative and the cover may be provided in any
shape desired, such as circular, oblong or irregular. In addition,
it is obvious that this invention is not to be limited to the exact
description disclosed, and that changes in detail and construction
may be made therein within the scope of the invention without
departing from the spirit thereof.
Inflatable tubes may be sewn or otherwise attached to the cover
cloth for arching it over fresh concrete. For example, an
inflatable tube of 2 or 3 inches diameter may be sewn around the
periphery of a 12 ft. .times. 71/2 ft. drop cloth inside the weight
tubes as described for the device of FIG. 1. A single inflatable
tube across the center, e.g., on the center 6 feet from each end,
along with the end inflatable tubes permits the cover cloth to be
arched over fresh concrete.
