Description

TECHNICAL FIELD

The present invention relates generally to drop cloths, and more specifically without limitation, slip resistant drop cloths.

BACKGROUND OF TITHE INVENTION

It is common in the construction and painting industry to use drop cloths to provide surface protection at a work site. By using drop cloths, a painter can prevent stray paint, splatter or other unwanted materials or chemicals from coming into contact with surfaces such as floors, walls, doors, countertops, marble, linoleur le, glass, furniture, staircases, or any other type of surface at the work site. One of the main reasons for using a drop cloth is to eliminate the need to repair and/or replace such surfaces. If there is a spill, the user will merely incur the cost and effort of deploying a drop cloth in the work zone rather than having to clean up and/or repair the affected area.
The use of drop cloths in the work zone can pose serious safety issues such as slippage to both the user and/or other individuals who need to walk on the top surface of the deployed drop cloth. For instance, a painter typically places drop cloths on the floor of a room that is to be painted so that it covers the entire room, and then proceeds to paint the walls of the room while standing on top of the drop cloths. Because the painter stands and works while standing on the drop cloths, the painter may slip when using the drop cloths on a variety of work. surfaces, including hardwood floors, vinyl, tile, and marble. Even worse, a painter's customer(s) can also slip and/or fall on a deployed drop cloth especially if the drop cloth has to remain in the work zone for an extended period of time.
A painter or user of a drop cloth can also experience other types of slippage problems. For example, a ladder that is placed on a drop cloth can easily slip or slide when a painter or a user leans side to side, or leans forward or backwards on the ladder while using a drip cloth in the work zone. This issue can be even further exacerbated when the work zone includes or encompasses a stair case made of hard wood, which increases the chances of injury do to slippage.
Some drop cloths are fabricated cheaply and in large quantities since a typical work site may require a large area to be covered. Because of this requirement, a typical drop cloth may be made of a cheap, light and flexible material that is readily available such as canvas which can be very slippery when placed on a floor or when placed on other surfaces. Essentially, walking across a conventional canvas can cause the bottom portion of the canvas to slip and slide across floors and surrounding furniture. As such, conventional canvas is difficult to use as a drop cloth since a painter and/or other individuals standing on a piece of the canvas may easily slip and fall.
Additionally, some drop cloths are formed by stitching canvas with another rubber coated fabric together, to prevent slippage. However, the stitching process may be impractical for large-scale processes, and the stitches themselves may be bulky. Further, the stitches may not be guaranteed to be leak-resistant or leak-proof.
Other slip resistant drop clothes have been developed, such as the drop cloth described by Frantellizzi in U.S. Pat. No. 7,833,619 B2. The '619 patent describes a drop cloth comprised of a non-linear contoured topographical surface having a slip reducing feature comprised of dot technology. This slip resistant drop cloth is cumbersome to manufacturer because the rubberized dots are very hard to bond in a uniform fashion to the drop cloth making it expensive to produce. In essence, it is very difficult to produce rubberized dots having a uniform center, diameter, height and spacing between them.
In light of the shortcomings in the prior art, there is clearly a need for a slip resistant drop cloth that addresses the above-identified problems.

Referring now to the drawings, FIG. 1 refers to one embodiment of the slip resistant drop cloth 100. The drop cloth 100 is comprised of an elongated body made from a material having a desired shape and weight commonly used in the construction or painting industry, namely a rectangle shape, as illustrated in FIGS. 1 and 2. The body of the drop cloth 100 will include a front side 3, a back side 5, a first end 10, a second end 20, a third end 30, and a fourth end 40 as illustrated in FIGS. 1 and 2.
As illustrated in FIG. 2, the back side 5 of the drop cloth 100 includes a slip reducing feature made of a plurality of parallel slip resistant ridges 50 extending from the first end 10 to the second end 20 and covering the back side 5 from the third end 30 to the fourth end 40. Moreover, the plurality of ridges 50 are bonded to the material that comprise the drop cloth 100. When filly deployed on a surface, the ridges 50 enable the drop cloth 100 to remain continuously in one place without slipping or sliding.
In another embodiment of the invention, the slip resistant ridges 50 are made from silicone. In fact, there are many brands of silicone that can be used to make the ridges 50. For instance, DAP Products Inc. makes various sealant products such as DAP® 100% Silicone (hereafter DAP). DAP is a registered trademark, and this company is one of the leading marketers of caulks, sealants, adhesives, insulating foams, spackling, glazing, and other general patch and repair products. The DAP silicone is formulated to create a long-lasting watertight and weatherproof seal with superior flexibility and adhesion to a variety of materials. When cured, it is mold and mildew resistant and will not crack or shrink. Moreover, DAP silicone is low in odor, and has a minimum to maximum operating temperature of −65° F. to ±400° F. Similarly, the application temperature for the DAP silicone is between −35° F. to 140° F.
Referring now to FIG. 3, each ridge 50 on the drop cloth 100 has a common height H 50(a), wherein said height H 50(a) is about one-thirty-seconds ( 1/32) of an inch to about one-eighth (⅛) of an inch. The preferred height of each ridge on said drop cloth 100 is one-sixteenth ( 1/16) of an inch.
Referring now to FIG. 4, each ridge 50 on the drop cloth 100 also has a common width W 50(b), wherein said width W 50(b) is about one-thirty-seconds ( 1/32) of an inch to about three-thirty-seconds ( 3/32) of an inch. The preferred width of each ridge on the drop cloth 100 is one-sixteenth ( 1/16) of an inch.
Referring now to FIGS. 2-4, the ridges 50 on the drop cloth 100 also have a common space S 75 between them, wherein said space S 75 is about one-eighth (⅛) of an inch to about one-fourth (¼) of an inch. The preferred spacing between each ridge 50 on the drop cloth 100 being three-sixteenths 3(/16) of an inch.
In FIGS. 1-2, the present invention includes a body having a desired shape, such as a square, rectangle, triangle, circle, oval, or other practical shape, common sizing including but not limited to 10′×12′, 9′×12′ and 12′×15′. Nevertheless, FIGS. 1-2 depict a more common shape, namely a rectangle. The body of the drop cloth 100 is made from a material comprising canvas, linen, hemp, flax, cotton, woven cotton, polyester, or rayon taken alone, or in combination thereof, or with another material commonly known in the construction or painting industry.
FIG. 5a provides a bottom perspective view of a first trowel 500 having a sickled shaped leading edge 510 and a flat side 505 used for spreading a compound on the back side 5 of the drop cloth 100 such as silicone. The trowel 500 also has a handle 515.
FIG. 5b provides a bottom perspective view of a second trowel 550 having a sickled shaped leading edge 560 and a notched side 551 that is comprised of a plurality of notches used for forming the slip resistant ridges 50 on the back side 5 of the drop cloth 100. The trowel 550 also has a handle 570.
In FIG. 6, a suitable first trowel 500 having a sickled shaped leading edge 510 is illustrated in use, where the flat side 505 of the trowel 500 is used for spreading a silicone compound or any other suitable compound on the back side S of the drop cloth 100.
In FIG. 7, a suitable second trowel 550 having a sickled shaped leading edge 560 is illustrated in use, where the notched side 551 of the trowel 550 is used for forming the plurality of substantially parallel slip resistant ridges 50 on the back side 5 of the drop cloth 100. The ridges 50 can be comprised of silicone or any other compound suitable for forming said ridges 50,
The unique sickled shaped leading edge of the first trowel 500 and of the second trowel 550 prevents silicone or any other type of compound used to form the ridges 50 from spilling over the outer edges of either trowel and creating a mess. Further, the width of the first trowel 500 and of the second trowel 550 is made approximately to the same width of the drop cloth. This will speed up the process of manufacturing the drop cloths 100 since the slip resistant ridges 50 can be formed in just one spread.
