Description:

FIELD OF INVENTION

Current application relates with a muff net, especially relates with an elastic muff net for preventing tangling of coiled hoses and wires.

BACKGROUND OF THE INVENTION

Coiled wires and hoses are widely used in our daily life. A telephone jack line between a ground phone body and receiver is one example. Especially for a ground phone on a desk of office, the coiled jack line easily tangled and makes a user annoyed. That kind of inconvenience is acceptable as a small happening in everyday life. However, for gardeners tangled hose line causes some trouble. They must cut the water first and untwine all the hose. Time loss due to tangling is not negligible. Moreover, repeated tangle, folding in some part, and untwine of coiled hose, most of which are made of flexible plastics that are weak in repeated folding, may result in break of the hose it self. And once it is tangled and exposed to sunlight, the coiled hose deformed by the heat of sunlight and can not be coiled again. For coiled electric power lines, tangling may result in short in circuit. The result is more significant and may do damage to user and may starts fire. It is purpose of the current application to provide an anti-tangle means that not only prevents tangling of coiled hoses/lines but also protects them in both position of stretched and retracted. In stretched position the muff prevents tangling and in retracted position the muff makes it easy to store the coiled hoses/wires.

DESCRIPTION OF THE PRIOR ARTS

U.S. Pat. No. 6,845,559 to Choi illustrates a structure and a method for coupling a protective net to a flexible tube, comprising shaping the flexible tube, wrapping the flexible tube with the meshed protective net made of stainless steel, and welding both ends of the flexible tube to both ends of the protective net. A solution heating process for the flexible tube and welding process for the flexible tube and the protective net are simultaneously carried out under the same condition in the same furnace. As a result, the protective net and the flexible tube are uniform in terms of physical properties. Furthermore, intergranular corrosion of stainless steel by inevitable stress generated upon welding a flexible tube and a protective net using any one of conventional methods, and crevice corrosion between a welding ring and a flexible tube, are prevented.

U.S. Pat. No. 4,263,942 to Lenhart, et al. illustrates a support sheathing for use, for example, on tubular sausage casings, the sheathing forming a container for a cylindrical hollow rod made of a shirred tubular casing, the sheathing comprising a heat-shrinkable, net-like, plastic tubular material, the sheathing surrounding the tubular casing about its outer cylindrical surface and forming integral end portions for covering end portions of said tubular casing, said integral end portions of the sheathing having annular openings therein surrounded by an annular bead, whereby the end openings of the sheathing permit access to the interior cavity of the hollow rod.

None of the prior art illustrates an anti-tangle net muff shown as in the current application.

SUMMARY OF THE INVENTION

A telephone jack line between a ground phone body and receiver is one example of coiled wires. The coiled jack line easily tangled and makes a user annoyed. That kind of inconvenience is acceptable as a small happening in everyday life because the tangled line does not disturb communication through telephone. Some user enjoys tangling and untwines the tangle. However, for gardeners tangled hose line causes some trouble. They must cut the water first and untwine all the hose. Time loss due to tangling is not negligible. Moreover, repeated tangle, folding in some part, and untwine of coiled hose, most of which are made of flexible plastics that are weak in repeated folding, may result in break of the hose it self. For coiled electric power lines, tangling may result in short in circuit. The result is more significant and may do damage to user and may starts fire. It is purpose of the current application to provide an anti-tangle means that not only prevents tangling of coiled hoses/lines but also protects them in both position of stretched and retracted. In stretched position the muff prevents tangling and in retracted position the muff makes it easy to store the coiled hoses/wires. An anti-tangle muff for coiled materials; such as a coiled electric wires, coiled gardening hoses, air hose, and coiled telephone wires, is provided. The muff is comprised of a cylindrical net loomed with elastic threads. Retracted length of the muff is same as the retracted coiled hoses/coiled wires and fully stretched length of the muff is the same as the stretched length of the hoses/wires. Both ends of the muff are fastened to fit the diameter of wires and hoses. Distance between two neighboring net knots is less than half of the outer diameter of the coiled hoses/wires when retracted to prevent tangling of the coiled hoses/wires.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 is a perspective view of a coiled hose (1) tangled while use. It happens frequently while using a coiled hose to supply water to lawn (2) of a garden. A coiled gardening hose (1) easily tangles if change nozzle (3) direction of the hose (1) from here to there.

FIG. 2 is a perspective view of an anti-tangle net muff (4) for coiled hoses and wires according to current application retracted state and a coiled hose (5) in retracted state. The net muff (4) is loomed with a resilient material such as Nylon® yarn. Length (6) of the net muff (4) in retracted state is half of length (7) of the coiled hose (5) in retracted state. Length (6) of the net muff (4) when retracted is in a range of 10 centimeter to 1,000 centimeter. Diameter (8) of the net muff (4) is the same as outer diameter (9) of the coiled hose (5). To hold the coiled hose (5) inside of the net muff (4), distance (10) between two neighboring net knots (11) is less than half of the outer diameter (9) of the coiled hose (5). Diameter (8) of the net muff is in the range of 0.1 centimeter to 500 centimeter.

FIG. 3 is a perspective view of an anti-tangle net muff (4) for coiled hoses and wires according to current application covering a coiled hose (5) in a retracted state. Once the coiled hose (5) of FIG. 2 is inserted to the net muff (4), both ends (12-a), (12-b) of the net muff (4) are fastened by solid tie bands (13-a), (13-b) and adhered to respective ends of the hose (5) by glue. Due to resiliency of the net muff (4) that is shorter than the hose (5), the coiled hose (5) is fully retracted and easy to store.

FIG. 4 is an enlarged drawing of both ends, (12-a) and (12-b), of the anti-tangle net muff (4) according to current application. Both ends, (12-a) and (12-b), of the net (4) are fastened to respective ends of the hose (5) and fastened by solid tie bands, (13-a) and (13-b). Glue may be applied on there to make the fastening tighter.

FIG. 5 is a schematic drawing that showing the anti-tangle net muff (4) according to current application covering a coiled hose (5) in a stretched state. Due to the solid tie bands, (13-a) and (13-b), that are fastened and glued to each end of the coiled hose (5), the net muff (4) stretches with the coiled hose (5) and holds the hose (5) inside thereof.

FIG. 6 is a schematic drawing of a tangled coiled hose (5). When a user spray water to one part of a lawn and then spray to other corner of the lawn, user usually drag the nozzle (3) of the a coiled hose (5) to the other corner. Rest part of the coiled hose (5) used overlap each other. Then, one loop (5-1) of the coiled hose (5) is inserted between other loops, (5-2) and (5-3); of the rest part the hose (5). It can happen in any portion of the hose.

Once the coiled hose (5) is tangled, it takes a time to untwine and it disturbs the job. If the tangled hose (5) is left behind on a hot summer day under the sun, the hose may be deformed. Then the coiled hose (5) has to be abandoned.

FIG. 7 is a schematic drawing that shows how the net muff (4) according to current application prevents tangling of a coiled hose. Though some part of the coiled hose (5) used overlap each other, and one loop (5-4) of the coiled hose (5) is inserted between other loops, (5-5) and (5-6), of the rest part the hose (5). The net muff (4) blocks the loop (5-4) stick into a space between other loops, (5-5) and (5-6). It is easily return to a stretched state as shown in FIG. 5 if a user just pulls one end or the nozzle (3).

After use, the coiled hose (5) and the net muff (4) return to a state shown in FIG. 3. The net muff (4), according to current application, not only prevents tangling of a coiled hose/wire to save working hours but also makes it easy to store them in an organized state.
