FIG.1is a perspective view showing a mop mitt for car washing according to one embodiment of the present invention,FIG.2is a schematic view showing a state in which the outer peripheral portion of the mop mitt for car washing according to the embodiment of the present invention shown inFIG.1is folded, andFIG.3is a schematic view showing a state in which both side portions and middle portion of the mop mitt for car washing according to the embodiment of the present invention are sewn.

Referring toFIGS.1to3together, a mop mitt100for car washing according to an embodiment of the present invention includes: a first surface110sewn in the state in which the outer peripheral portion112thereof has been folded inward, and forming one surface of a pocket shape having one open side; and a second surface120extending from the first surface110, rotated around a central portion114, and facing the first surface110. The first and second surfaces110and120are sewn together by sewing second sewing portions140located on both sides of thereof, so that the mop mitt100for car washing is gripped through an insertion portion160having one open side.

The outer peripheral portion112of the mop mitt100for car washing according to the present invention refers to a size space between each end of the mop mitt100for car washing and a corresponding one of the first sewing portions130in the state in which the ends of the mop mitt100for car washing have been folded inward.

The fabric of the mop mitt100for car washing according to the present invention is configured to include threads having different thicknesses and lengths, i.e., first and second yarns. The outer peripheral portion112is folded to the inside of the mop mitt100for car washing and is sewn in the first sewing portion130so that the first and second yarns are directed outward. Accordingly, the first and second yarns are also directed in lateral directions to increase the contact area between the mop mitt100for car washing and a car, so that liquid or contaminants can be easily wiped away.

A yarn that is usable as the first yarn is not particularly limited, but is preferably at least one selected from the group consisting of a polyester yarn, a copolyester yarn, a polyamide yarn, and a polyethylene yarn. It is also preferable to use a polyester/polyamide synthetic yarn, polyethylene/polyamide synthetic yarn or polyester/copolyester synthetic yarn, or a polyester single yarn, polyamide single yarn or polyethylene single yarn.

In addition, a yarn that is usable as the second yarn is not particularly limited as long as it is known in the art, but is preferably at least one selected from the group consisting of a polyester yarn, a polyamide yarn, and a polyethylene yarn.

In one specific example, the third sewing portion150located in the middle portion of the mop mitt100for car washing is sewn such that an inner space is partitioned. In other words, the second sewing portions140located on both sides of mop mitt100for car washing are sewn together in the state in which the first and second surfaces110and120are superimposed on each other, and form a pocket forming the inner space.

The second sewing portions140located on both sides of the mop mitt100for car washing are both sides of the mop mitt100for car washing parallel to the central portion114folded around the center thereof and a direction opposite to the central portion114.

In addition, a third sewing portion150located in the middle portion is sewn to partition the inner accommodation space formed by the first and second surfaces110and120across which the second sewing portions140are sewn. In this case, it is preferable that the third sewing portion150be sewn along a direction parallel to the directions in which both the second sewing portions140are sewn.

Furthermore, in one specific example, a drain hole170may be formed in a part of the mop mitt100for car washing.

Both the second sewing portions140are sewn in the state of being spaced apart from ends of the central portion114, so that the drain hole170can be formed between both the second sewing portions140and the central portion114. Alternatively, the drain hole170may be formed by perforating a part of the mop mitt100for car washing.

FIG.4is a schematic plan view showing a mop body for car washing according to another embodiment of the present invention, andFIG.5is a schematic side view showing the mop body for car washing according to the other embodiment of the present invention.

The mop body1000for car washing according to the other embodiment of the present invention includes: a spreading plate200configured to be at least partially inserted into the insertion portion160having one open side between the first and second surfaces110and120of the mop mitt100for car washing, and to spread the mop mitt100for car washing; and a handle rod300coupled with the spreading plate200, and configured to allow the mop mitt100for car washing to wipe the surface of a car in such a manner that an operator grips and pushes/pulls the handle rod300with his or her hand. The spreading plate200includes: a support portion210configured to be inserted into the innermost part of the insertion portion160and to support the mop mitt100for car washing; and a bendable portion220configured to be bendable because it has lower rigidity than the support portion210.

It is preferable that in the mop body1000for car washing according to the other embodiment of the present invention, the support portion210and the bendable portion220be injection-molded using the same resin material in an integrated form.

In this case, injection molding is a manufacturing process for producing various parts by injecting molten materials into molds. An injection molding machine includes various components: a hopper configured such that chips are put thereinto, a heating vessel configured to heat and melt a raw material, a screw configured to push out the melted plastic, and a mold configured to mold the raw material into a desired shape.

First, the chips are weighed in a predetermined amount in the hopper, and are then transferred to the heating vessel. Then, they are melted while being pushed by the screw, and the molten plastic is then injected into the mold from an injection nozzle. As the mold has been cooled, the injected plastic solidifies immediately, and a molded product is automatically ejected from the mold.

Plastics are divided into thermoplastic plastics and thermosetting plastics. Thermoplastic plastics are polymers that melt when they are heated and return to a solid state when the temperature is sufficiently lowered. Many thermoplastic plastics are produced by polymer compounds that interact with weak intermolecular forces. Unlike thermosetting plastics, thermoplastic plastics melt when heated and return to their original state, so that they have the property of being recyclable. These include polyethylene, polyethylene terephthalate, polyvinyl chloride, polyvinylidene chloride, polystyrene, polypropylene, and the like.

In contrast, thermosetting plastics are plastics that do not melt and burn to form powder or generate gas when heat is applied, and do not melt again once hardened, unlike thermoplastic plastics. These include epoxy resins, amino resins, phenol resins, polyester resins, and the like.

It is obvious that in addition to the manufacturing method using such a plastic material, there may be possible a method in which the support portion210and the bendable portion220include rubber, a spring, or the like, so that the bendable portion220is bent with respect to the support portion210.

In one specific example, the bendable portion220is preferably thinner than the support portion210. In other words, the thickness t1of the bendable portion220is preferably smaller than the thickness t2of the support portion210.

Furthermore, flexible holes222or flexible slits are formed in the bendable portion220so that the rigidity of the bendable portion220is lower than that of the support portion210, and thus the bendable portion220can be bent. It is preferable that the flexible holes222have a shape having a length longer than a width in the longitudinal direction of the spreading plate200and a plurality of flexible holes222be formed to be spaced apart from each other.

In this structure, the handle rod300is detachably coupled to the spreading plate200, so that a handle rod301having a different length, i.e., a longer length than the short handle rod300, can be coupled to the spreading plate200. In addition to this feature, the handle rods300and301may be rotated toward the spreading plate200to facilitate storage, or the long handle rod301may be extended.

According to the present invention, injection Velcro strips224are provided on and screwed to both sides of one end of the spreading plate200. In other words, the injection Velcro strips224are located on both sides of one end of the spreading plate200, and screws are fastened through the injection Velcro strips224and the spreading plate200. Accordingly, the connecting portions of the spreading plate200and the handle rod300are firmly coupled to each other, and the injection Velcro strips224come into close contact the mop mitt100for car washing when they are coupled to each other.

Furthermore, the third sewing portion150formed in the middle portion of the inner side of the insertion portion160is located in the cutout slot212of the spreading plate200. In this case, the third sewing portion150is a portion formed by sewing both inner sides of the mop mitt100for car washing. In addition, the cutout slot212is formed in the central portion of the support portion210, so that the support portion210may be bent around the cutout slot212.

Accordingly, when an operator washes a car using the mop body1000or a hand, the mop mitt100for car washing is brought into close contact with the mop body1000or both sides of the hand by the third sewing portion150formed in the middle portion of the inner side of the insertion portion160.

FIG.6is a schematic view showing the use of the mop body for car washing according to the other embodiment of the present invention.

Referring toFIG.6together withFIGS.1to5, the operating relationship between the mop mitt100for car washing and the mop body1000for car washing according to the present invention will be described. First, the outer peripheral portion112of the mop mitt100for car washing is folded inward and then sewn.

The insertion portion160having one open side is formed by folding the mop mitt100for car washing around the central portion114and then sewing the second sewing portions140on both sides of the first and second surfaces110and120.

In this case, the drain hole170is formed between the second sewing portions140and the central portion114by sewing the second sewing portions140in the state of being spaced apart from ends of the central portion114.

Then, the third sewing portion150in the middle portion of the pocket-shaped inner space of the mop mitt100for car washing is sewn to partition the pocket-shaped inner space.

In the case where the mop body1000for car washing is used, the mop body1000for car washing is inserted into the insertion portion160that is open in one side of the mop mitt100for car washing.

An operator wipes the surface of the car10while holding the mop body1000for car washing, inserted into the mop mitt100for car washing, with a hand and pushing or pulling it.

In this case, the spreading plate200is configured to include the support portion210configured to support the mop mitt100for car washing and the bendable portion220configured to be bendable because it has lower rigidity than the support portion210. In the upper portion of the car10, i.e., in a portion that is difficult for a hand to reach, the bendable portion220is bent, so that the support portion210comes into close contact with the car10. Also, even when the lower part of the vehicle10is washed, the bendable portion220is bent along the exterior of the vehicle10, so that the support portion210comes into contact with the vehicle10. As described above, when the bendable portion220is bent with respect to the support portion210, the area where the mop mitt100for car washing comes into contact with the car10increases, thereby increasing the area of the vehicle10that can be wiped.

Accordingly, in the case where the mop mitt for car washing according to the present invention is gripped with a hand and then used, the mop mitt for car washing may be conveniently used, with the insertion portion160in which the pocket-shaped inner space is partitioned being gripped.

Furthermore, when the mop mitt for car washing and the mop body for car washing according to the present invention are combined with each other and then used, a washing effect can be improved by increasing a contact area between the mop mitt for car washing and a car, and there is provided the effect of easily washing all parts of a car that are difficult for a hand to reach.

FIG.7is a flowchart showing a method of manufacturing a mop mitt for car washing according to another embodiment of the present invention.

Referring toFIG.7together withFIGS.1to6, the method of manufacturing a mop mitt for car washing according to the present embodiment will now be described. First, the outer peripheral portion112of the mop mitt100for car washing is folded inward and then sewn at step S110.

The mop mitt100for car washing in which the outer peripheral portion112has been folded as described above is folded around the central portion114so that the first and second surfaces110and120in which the outer peripheral portion112has been sewn face each other at step S120.

The insertion portion160having one open side is formed to make a pocket shape by sewing the second sewing portions140on both sides of the first and second surfaces110and120made to face each other through the folding around the central portion114at step S130.

In this case, the drain hole170may be formed between the second sewing portions140and the central portion114by sewing the second sewing portions140in the state of being spaced apart from ends of the central portion114.

Then, the third sewing portion150in the middle portion of the pocket-shaped inner space of the mop mitt100for car washing is sewn to partition the pocket-shaped inner space at step S140.

Accordingly, when the pocket-shaped inner space is partitioned and a hand or the mop body for car washing is inserted and grips the mop mitt for car washing through the insertion portion, the mop mitt for car washing may be prevented from being shaken or separated and be conveniently used.

Accordingly, the mop mitt for car washing according to the present invention may provide the effect of facilitating the use of the mop mitt for car washing by allowing a hand or the mop body for car washing to be inserted into the pocket-shaped inner space, and may also provide the effect of shortening washing time by increasing a contact area between the mop mitt for car washing and a car.

Furthermore, the mop mitt for car washing according to the present invention is convenient to use, and can wash a car within a short period of time, thereby improving the efficiency of car washing.

The mop mitt for car washing according to the present invention has the following effects:

First, the mop mitt for car washing is convenient to use because it has a pocket-shaped inner space and is thus easy to grip.

Second, the mop mitt for car washing may conveniently perform car washing because the mop mitt for car washing can be used by hand and can be used in combination with the mop body for car washing.
