Roll-a-seal

[0001] This invention relates to the safer and more convenient use of heavy duty or construction type extension cords when joining two or more extension cords together and using them to power an electrical product such as tools, machinery or lights.

[0002] Extension cords are used to expand the working area when working with electrical products. Sometimes they are used in wet environments and this can cause a safety hazard by electrocution. Keeping water away from the exposed electric connections such as extension cord plugs can be difficult In part, because of this problem Ground Fault Interrupter outlets and breakers were created. When used, Ground Fault Interrupters will trip or stop electric current from flowing to equipment so fast it prevents serious electrical injury. When used in a wet environment, the Ground Fault Interrupter can trip so many times it disrupts the use of electric tools to the point of causing work to stop until drier conditions exist. I created the Roll-A-Seal plug to prevent these problems. This invention makes extension cord connections waterproof. When electric connections are encapsulated by the Roll-A-Seal product, water or other liquids cannot get to the electrical contacts eliminating the safety and convenience problems that can be otherwise experienced. Electric connections on extension cords are subject to corrosion when they get wet and cords with dampness in the plugs cannot be used when used with Ground Fault Interrupter outlets. These cords must be allowed to dry thoroughly before again being used when Ground Fault Interrupter outlets are being used. This can take several days and can cause the necessity of having many extension cords on hand. Roll-A-Seal was designed to prevent these problems. When two or more extension cords are being used, to prevent the cord plugs from pulling apart and separating, they are often tied together by various means. Sometimes this puts a strain on the area where the cord joins the plug. Roll-A-Seal holds the joined plugs together in the most efficient way possible by friction grip and in their intended position. This invention creates a simple, safe and convenient way to join two or more extension cords together.

[0003] This invention has taken construction type extension cords and made them safer, more convenient with simple modification in adding a molded latex cover fused to its base so it can be rolled out like rolling down a shirt sleeve onto itself and a joined plug creating a water proof seal and a means to securely hold the joined plugs together until they are unrolled to separate. This invention can save time, lives and money.

[0004] FIG. 1 shows the {fraction (1/16)} inch thick latex sleeve rolled up into itself.

[0005] FIG. 2 shows the female plug of the extension cord not covered by the latex sleeve and not joined to the male plug.

[0006] FIG. 3 shows the male plug of the extension cord not covered by the latex sleeve and not joined to the female plug.

[0007] FIG. 4 shows the {fraction (1/16)} inch thick latex sleeve rolled up into itself.

[0008] FIG. 5 shows the {fraction (1/16)} inch thick latex sleeve on the female plug rolled up into itself.

[0009] FIG. 6 shows the male and female plugs joined together with the male latex sleeve rolled out onto and covering both plugs.

[0010] FIG. 7 shows the latex sleeve of the male plug rolled out over itself and onto the female plug covering both of them.

[0011] FIG. 8 shows the latex sleeve of the female plug rolled out over the latex sleeve of the male plug creating a double seal over both the male and female plugs which are joined together.

[0012] FIG. 9 shows the male and female pugs joined together and encapsulated by both latex sleeves.

[0013] FIG. 10 shows the male plug with its latex sleeve covering itself and the female plug and the latex sleeve of the female plug over the male sleeve completing the waterproof seal.

[0014] The shown embodiments illustrated in FIGS. 1 and 2 show the female plug by itself with the {fraction (1/16)} inch thick latex sleeve in its unused condition but allowing the extension cord to function to conduct electricity from a power source to an electrical product. FIGS. 3 and 4 show the male plug in the same condition. FIGS. 5, 6 and 7 show the first step of the procedure in sealing the male and female plugs now joined with the male latex sleeve fully extended creating a friction bond over the two plugs. FIGS. 8, 9 and 10 show the male and female plugs joined, encapsulated by two layers of {fraction (1/16)} inch thick latex rubber sleeves which create a waterproof seal and friction bond holding the two plugs together. This creates in effect, one extension cord that can be used in wet environments and submerged in water without water causing a safety or convenience problem.

[0021] FIG. 2, number 7 shows the latex sleeve of the male plug rolled out over itself and onto the female plug covering both of them.

[0022] FIG. 3, number 8 shows the latex sleeve of the female plug rolled out over the latex sleeve of the male plug creating a double seal over both the male and female plugs which are joined together.

[0023] FIG. 3, number 9 shows the male and female pugs joined together and encapsulated by both latex sleeves.

[0024] FIG. 3, number 10 shows the male plug with its latex sleeve covering itself and the female plug and the latex sleeve of the female plug over the male sleeve completing the waterproof seal.
