Description

Description CAR GLASS CLEANER

Technical Field

[1] The present invention relates, in general, to car window cleaners used for washing car windows in every season regardless of changes in the weather and, more particularly, to a car window cleaner, which includes a handle to be grasped by the hand of a user, and a window cleaning part which is provided on a first end of the handle and serves to wash a car window, and in which a coupling part is provided at a predetermined position through the handle, so that a water container or water hose is coupled to the coupling part. Background Art

[2] Generally, car windows are affected by changing seasons. For example, in the summer, a windshield of a car may be soiled with various foreign substances, such as dust, muddy water, etc., or may be stained by bugs striking the windshield. In this case, a user operates a windshield wiper to wipe the windshield.

[3] As such, in the case that the windshield is wiped by the windshield wiper, general foreign substances such as muddy water are easily removed by the windshield wiper, but a bug impact stain is not easily washed, so that, although the windshield is wiped by the windshield wiper, the windshield may still be messy. Therefore, if the car travels a relatively long distance, the clear sight of the user may be obscured.

[4] Furthermore, in the case that a rear windshield and side windows are covered with morning dew, the user must wipe them some other way.

[5] However, because most cars have no special window brush for the side windows or the rear windshield, it is difficult to wipe the side windows and the rear windshield clean.

[6] Meanwhile, in the winter, the car window is often covered with frost or snow. If the user has to immediately use the car, for example, to go to work in the morning, it is necessary to rapidly remove the frost or snow from the car window.

[7] The above-mentioned situations mainly arise when it is impossible to wash the entire car, for example, when the car is on an express highway or at a busy time such as when the user has to go to work in the morning.

[8] Therefore, this interferes with careful driving and comfortable travel and may make it impossible for the user to get to work on time. To solve the above problems, a car window cleaner that makes it possible to wipe both front and rear windshields clean in a short time is required. Disclosure of Invention Technical Problem

[9] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a car window cleaner, which, in the summer, makes it possible to easily wash a car window using a variety of kind of potable water containers or a dedicated water container regardless of the location of the car before it starts and also during a trip, and which, in the winter, makes it possible to easily remove frost or snow using a saw- toothed blade or a planar blade or to rapidly remove frost using hot water, alcohol or an antifreeze solution.

[10] Another object of the present invention is to provide a car window cleaner which makes it possible to easily push and remove snow that has piled on the car window, hood or roof, using a window cleaning part thereof. Technical Solution

[11] In order to accomplish the above objects, the present invention provides a car window cleaner, including: a handle to be grasped by a hand of a user; and a window cleaning part provided on a first end of the handle to wash a car window, wherein a coupling part is provided at a predetermined position through the handle, so that a water container or water hose is coupled to the coupling part.

[12] The coupling part may be provided at the predetermined position through the handle, and may include: a through hole formed through the coupling part, with an internal threaded part formed on a circumferential inner surface of the through hole.

[13] The coupling part may be provided at the predetermined position through the handle, and may include: a through hole formed through the coupling part, with an internal threaded part formed on a circumferential inner surface of the through hole. Threads of first and second ends of the internal threaded part may be formed in opposite directions such that the water container or water hose is coupled to any one selected from among first and second ends of the coupling part.

[14] Furthermore, an internal threaded part or an external threaded part may be formed on at least one of first and second ends of the coupling part provided in the handle.

[15] The car window cleaner may further include: a window brush unit, having a coupling protrusion coupled to one end of the coupling part of the handle and communicating with a remaining end of the coupling part, a skirt-shaped part integrally extending from a circumferential outer surface of an end of the coupling protrusion such that the coupling protrusion and the skirt-shaped part communicate with each other, and a sponge member provided in the skirt-shaped part.

[16] The coupling part may include a through hole formed at the predetermined position through the handle; and a coupling pipe, with a stop ring provided at a medial position on a circumferential outer surface of the coupling pipe, the stop ring having a diameter greater than an inner diameter of the through hole, so that a portion of the coupling pipe which is provided at one side of the stop ring is inserted into the through hole and is coupled to the water container or water hose.

[17] The handle may have a mounting groove in the first end thereof, and the window cleaning part may have an insertion protrusion on a surface thereof, so that the insertion protrusion of the window cleaning part is inserted into and fastened to the mounting groove of the handle.

[18] The window cleaning part may include: a planar blade part integrally extending from the first end of the handle in a longitudinal direction of the handle, the planar blade part having a planar edge; and a rubber blade part fitted into a mounting slot, which is formed in the first end of the handle in a latitudinal direction of the handle.

[19] The window cleaning part may include: a planar blade part integrally bent from the first end of the handle towards a first side of the handle and having a planar edge; and a saw-toothed blade part integrally bent from the first end of the handle towards a second side of the handle and having a saw-tooth-shaped edge.

[20] The window cleaning part may include: a planar blade part integrally bent from the first end of the handle towards a first side of the handle and having a planar edge; and a removable holding part integrally bent from the first end of the handle towards a second side of the handle, with an insertion slot formed in an edge of the removable holding part. One selected from a group of cleaning members including a saw-toothed blade made of metal or hard synthetic resin, a wiper made of rubber, a wiper made of soft foam, a wiper made of natural or synthetic pulp, a wiper made of fabric, and a brush may be fitted into the insertion slot of the removable holding part.

[21] The window cleaning part may include: a pair of removable holding parts integrally bent from the first end of the handle towards respective first and second sides of the handle, with an insertion slot formed in an edge of each of the removable holding parts. One selected from a group of cleaning members including a saw-toothed blade made of metal or hard synthetic resin, a wiper made of rubber, a wiper made of soft foam, a wiper made of natural or synthetic pulp, a wiper made of fabric, and a brush may be fitted into the insertion slot of each of the removable holding parts.

[22] The handle may be adjustable in length.

[23] The handle may include: a grip pipe; a length adjustment rod inserted into the grip pipe, with a window cleaning part provided on a first end of the length adjustment rod, and an external threaded part, having a reverse conical shape, formed on a second end of the length adjustment rod; and a locking member, with an internal threaded part formed on a circumferential inner surface of the locking member and engaging with the external threaded part of the length adjustment rod, and a slit longitudinally formed in the locking member.

Advantageous Effects

[24] In a car window cleaner of the present invention, a coupling part is provided at a predetermined position through a handle, and a water container, such as a potable water container, or a water hose is tightly coupled to the coupling part. Thus, in any season, the present invention makes it possible to easily wash a car window using water supplied from the water container or the water hose. In particular, in the winter, the present invention makes it possible to rapidly remove frost using hot water or an antifreeze solution. Furthermore, it is possible to remove frost using only a saw- toothed blade part or rubber blade part without using the water container.

[25] Moreover, in the present invention, a through hole is formed through the coupling part, and an internal threaded part is formed on the circumferential inner surface of the through hole. The threads of opposite ends of the internal threaded part are formed in opposite directions such that the water container or water hose is coupled to either of the opposite ends of the coupling part. Therefore, depending on the intended use of the window cleaning part, which has several blade parts, such as a planar blade part, a saw-toothed blade part and a rubber blade part, on an end thereof, the water container can be coupled to either of the opposite ends of the coupling part so as to be located on a desired side.

[26] Furthermore, the window cleaning part of the car window cleaner of the present invention may be used for pushing and removing snow piled on the car window, hood and roof. In particular, because the handle may have a structure such that it is adjustable in length, the present invention makes it possible for the user to easily remove even snow that is far away from the user.

[27] As well, in the present invention, at least one removable holding part, having an insertion slot, may be provided on the window cleaning part. Thereby, a planar blade, a saw-toothed blade, a brush, a sponge member or a water tissue wiper is selectively inserted into the insertion slot according to the intended use, thus being convenient for the user.

[28] In particular, in the case that the present invention is used after connecting the coupling part of the handle to a water hose that extends from a faucet, the user can wash the car more conveniently.

[29] As such, the car window cleaner of the present invention is advantageous in that, when a car window becomes dirty, the user can easily and efficiently wash the car window using the car window cleaner regardless of time and place in every season, that is, in the summer as well as in the winter.

Best Mode for Carrying Out the Invention [57] [First embodiment]

[58] FIG. 1 is a perspective view of a car window cleaner, according to a first embodiment of the present invention. FIG. 2 is a view schematically illustrating a method of coupling a water container to an internal threaded part of a coupling part through a threaded engagement. [59] As shown in FIG. 1, the car window cleaner according to the first embodiment of the present invention includes a handle 10, a window cleaning part 30 and a coupling part 50. [60] The handle 10 allows a user to hold it using his/her hand and is not limited to any particular shape or structure, so long as the user is able to hold it using his/her hand without inconvenience. In particular, in FIG. 1, the handle 10 has a rectangular column shape having a predetermined thickness and width, but the present invention is not limited to this. That is, the handle 10 may have a cylindrical or other shape. [61] Furthermore, it is preferable that the handle 10 be made of hard synthetic resin, such that the handle 10 has appropriate properties such as strength and is easily adapted to mass production at low cost. [62] The handle 10 is at a first end thereof relatively wide, as shown in FIG. 1, so that the window cleaning part 30 is stably integrated with the extension part of the handle

10. Furthermore, thanks to the extension part of the handle 10, although the coupling part 50 is formed in the first end of the handle 10, even if outside force is applied to the handle 10, the handle 10 is prevented from being damaged. [63] Meanwhile, the window cleaning part 30 serves to remove foreign substances, such as muddy water, a bug impact stain, frost, and snow, applied to the car window. As shown in FIG. 1, the window cleaning part 30 is integrated with the handle 10. [64] Furthermore, as shown in FIG. 1, the window cleaning part 30 includes a s aw- toothed blade part 301, which integrally extends from the first end of the handle 10 in a longitudinal direction of the handle 10, and a wiper part 302, which is made of rubber and is perpendicularly provided on the first end of the handle 10.

[65] The saw-toothed blade part 301 of the window cleaning part 30 serves to scrape and remove frost, which covers the window of the car in the winter, from the window. Of course, in place of the saw-toothed blade part 301, a planar blade part having no saw teeth may be provided on the window cleaning part 30.

[66] The wiper part 302 is used for removing foreign substances, such as muddy water, which are relatively easily removed from the window of the car without scratching the window. As shown in FIG. 1, the wiper part 302 is inserted into and fastened to an insertion slot 304 of a fastening protrusion 303, which is perpendicularly provided on the first end of the handle 10.

[67] The coupling part 50 has a through hole, which is formed at a predetermined position through a side of the handle 10, and an internal threaded part 510, which is formed on the circumferential inner surface of the through hole.

[68] The internal threaded part 510 serves to couple a water container or a water hose to the car window cleaner. The diameter of the through hole and the pitch of the internal threaded part 510 are determined depending on those of an external threaded part 732 formed on a water container 730.

[69] In particular, it is preferable that threads of opposite sides of the internal threaded part 510 be formed in opposite directions such that the water container or water hose can be coupled to either side of the coupling part 50.

[70] Meanwhile, at least one end of the coupling part 50 may protrude from a surface of the handle 10, and an external threaded part may be formed on the end of the coupling part 50 that protrudes from the surface of the handle 10, so that a peripheral device to be used for cleaning the car window may be screwed to the coupling part 50.

[71] Here, the peripheral device is a device which adjusts the amount of water to be discharged such that water is prevented from being excessively discharged from the water container through the through hole at one time, a device which increases a spray region of water, or a device which has a substance, such as a sponge, that absorbs some of the discharged water so as to reduce the amount of water used for cleaning the car window.

[72] As shown in FIG. 2, in the case that the car window cleaner of the present invention, which is provided with the water container 730 screwed to the external threaded part 510 of the coupling part 50, is used for cleaning a car window, because water contained in the water container 730 is discharged onto the car window, the car window can be more thoroughly cleaned by the window cleaning part 30. Furthermore, in the winter, hot water or antifreeze solution may be charged in the water container 730 and used for removing frost from the car window more easily. Mode for the Invention

[73] [Second embodiment]

[74] FIG. 3 is a perspective view of a car window cleaner, according to a second embodiment of the present invention. FIG. 4 is a perspective view showing a car window cleaner having a window cleaning part provided with a removable holding part in place of a planar blade part. FIG. 5 is a perspective view showing a car window cleaner, in which window cleaning parts are provided on opposite ends of a handle.

[75] Unlike the first embodiment, in the car window cleaner according to the second embodiment, as shown in FIG. 3, the window cleaning part 30, which is integrally provided on a first end of a handle 10, includes a removable holding part 310, which has an insertion slot 312 in an edge thereof, and a planar blade part 330. The removable holding part 310 and the planar blade part 330 are bent from the first end of the handle 10 in opposite directions.

[76] Meanwhile, as shown in FIG. 4, the window cleaning part 30 may include another removable holding part 310 in place of the planar blade part 330. Furthermore, in place of the planar blade part 330, a saw-toothed blade part may be provided.

[77] As well, as shown in FIG. 5, the window cleaning part 30 may be provided on each of the opposite ends of the handle 10.

[78] FIGS. 6 through 11 are perspective views showing window cleaning members. FIG.

12 is an exploded perspective view of the window cleaning member of FIG. 10. FIG.

13 is a perspective view schematically showing a washing tissue wiper packed with a vinyl bag.

[79] As shown in FIGS. 3 through 5, the insertion slot 312 is formed in the removable holding part 310, so that a window cleaning member 350 is simply and removably inserted into the insertion slot 312. According to the intended purpose, one selected from a planar scraping blade of FIG. 6, which is made of metal or hard synthetic resin, a saw-toothed scraping blade of FIG. 7, which is made of metal or hard synthetic resin, a wiper of FIG. 8, which is made of rubber, a wiper of FIG. 9, which is made of soft foam, a washing tissue wiper of FIG. 10, which is made of natural or synthetic pulp or fabric, and a brush wiper of FIG. 11 is coupled to each of the removable holding parts 310 of FIGS. 3 through 5.

[80] For example, in the case that the car window is covered with frost, the planar scraping blade of FIG. 6 or the saw-toothed scraping blade of FIG. 7 is coupled to the removable holding part 310. Furthermore, when it is desired to remove foreign substances staining the car window, the wiper of FIG. 8, made of rubber, the wiper of FIG. 9, made of soft foam, the wash tissue wiper of FIG. 10, made of fabric, or the brush wiper of FIG. 11 is coupled to the removable holding part 310 and used for removing the foreign substances.

[81] As such, in this embodiment, the planar scraping blade or the like is selectively coupled to the removable holding part 310 of the window cleaning part 30 according to the intended use. Furthermore, there is an advantage in that, even if the planar scraping blade or the like is damaged, only the damaged blade or the like need be replaced with a new one.

[82] Meanwhile, in the case that the saw-toothed scraping blade of FIG. 7 is made of metal, it is preferred that anti-scratch tips 352 be provided at regular intervals to prevent the car window from being scratched when removing frost, as shown in FIG. 7. Each anti-scratch tip 352 is made of hard synthetic resin and configured such that it protrudes beyond the saw teeth of the metal blade, that is, such that the height thereof is slightly greater than that of each saw tooth, as shown in FIG. 7.

[83] In particular, as shown in FIG. 12, the wash tissue wiper of FIG. 10, which is made of natural pulp, synthetic pulp, or fabric, comprises a bracket 354, which has a '

¹U¹

'-shaped cross-section and is removably inserted into the insertion slot 312 of the removable holding part 310, and a wash tissue unit 356, which is inserted into a space defined in the bracket 354 and is made of multi-layered pulp or fabric sheets.

[84] Here, it is preferable that an auxiliary plate made of rubber be provided on the inner surface of the bracket 354 such that the wash tissue unit 356 is securely fastened to the bracket 354.

[85] In anticipation of when the wash tissue unit 356 becomes so dirty or severely damaged that it is impossible to use it, the present invention has a structure such that, when required, a user separately purchases a new wash tissue unit 40, which is marketed in the state of being packed as shown in FIG. 13, and easily replaces the existing wash tissue unit 356 with the new one. Furthermore, preferably, the packed wash tissue unit 356 is wet with washing agent such that the user may efficiently wipe the car window using the wash tissue unit 356 immediately after purchasing it.

[86] FIG. 14 is a perspective view of a car window cleaner of the present invention, to which a water container having a separate stopper to be screwed to the bottom of the water container is coupled.

[87] As shown in FIG. 14, an external threaded protrusion 154 and an internal threaded hole 152 may be provided on a second end of a handle 10, so that the stopper of the water container 730 is coupled to one of them. In other words, the external threaded protrusion 154 and the internal threaded hole 152 serve to store the stopper to prevent it from being lost.

[88] Furthermore, a coupling hole 734, having an internal threaded part on the circumferential inner surface thereof, is formed through the bottom of the water container 730 having therein a receiving space, as shown in FIG. 14. The stopper 736 is selectively screwed to the coupling hole 734. Preferably, the stopper 736 is connected to a predetermined position of the water container 730 by a connection member 738, thus preventing the stopper 736 from being lost.

[89] FIG. 15 is a perspective view showing a car window cleaner of the present invention, in which a discharge guide plug storage hole and a plug stopper storage hole are provided in an end of a handle. FIG. 16 is a perspective view showing a water discharge guide plug. FIG. 17 is a perspective view showing a plug stopper.

[90] As shown in FIG. 15, in the present invention, the discharge guide plug storage hole

192 and the plug stopper storage hole 194 may be formed in the first end of the handle 10. When the water discharge guide plug 610 of FIG. 16 and the plug stopper 630 of FIG. 17 are not in use, they are respectively stored in the discharge guide plug storage hole 192 and the plug stopper storage hole 194. To use them, the water discharge guide plug 610 or the plug stopper 630 is removed from the discharge guide plug storage hole 192 or the plug stopper storage hole 194 and coupled to an end of the coupling part 50 which is at a position opposite the water container. Alternatively, the water discharge guide plug 610 may be press-fitted into the opening of the water container, and, thereafter, the water container may be screwed to the coupling part 50, which is provided in the handle 10.

[91] Here, because a plurality of holes is formed through the upper surface of the water discharge guide plug 610, the use of the water discharge guide plug 610 is advantageous in that the car window is efficiently washed despite the use of a relatively small amount of water.

[92] FIG. 18 is a perspective view showing a car window cleaner, in which an internal threaded part is formed in each end of a coupling part. FIG. 19 is a side view showing the car window cleaner of FIG. 18. FIG. 20 is a perspective projected view of the coupling part.

[93] As shown in FIGS. 18 and 19, in the present invention, the internal threaded part

510 may be formed on each of the first and second ends of the coupling part 50 which protrude from the first and second surfaces of the end of the handle 10, such that a water container is coupled to either end of the coupling part 50. That is, in this case, the water container can be selectively coupled to either end of the coupling part 50 through a threaded engagement according to the intended use.

[94] Furthermore, as shown in FIG. 20, a partition wall 530, having at least one through hole 550 therein, may be provided at a medial position in the coupling part 50. The partition wall 530 makes it possible for the water container to watertightly engage with the coupling part and prevents excess water from being discharged from the water container in the opposite direction. [95] FIG. 21 is a perspective view showing a car window cleaner, in which an external threaded part and an internal threaded part are respectively formed on first and second ends of a coupling part. FIG. 22 is a side view showing the car window cleaner of FIG. 21.

[96] Unlike the car window cleaner shown in FIGS. 18 and 19, in the car window cleaner of FIGS. 21 and 22, the external threaded part 570 is formed on the first end of the coupling part 50 which protrudes at a predetermined position from the first surface of a handle 10. Furthermore, the internal threaded part 510 is formed on the second end of the coupling part 50 which protrudes from the second surface of the handle 10.

[97] The internal threaded part 510 of the coupling part 50 engages with an external threaded part formed on the mouth of the water container, and the external threaded part 570 of the coupling part 50 is coupled to a peripheral device through a threaded engagement.

[98] FIGS. 23 and 24 are perspective views showing a window brush unit. FIG. 25 is a perspective view showing a window brush unit, which includes a coupling protrusion having an external threaded part thereon.

[99] As shown in FIGS. 23 and 24, the window brush unit 90, which is a kind of peripheral device, includes the coupling protrusion 910, which has an internal threaded part thereon so that it is watertightly screwed to an external threaded part of a coupling part 50, and a skirt-shaped part 930, which integrally extends from the circumferential edge of one end of the coupling protrusion 910 and has a single or more ply structure.

[100] The window brush unit 90 having the above-mentioned structure is advantageous in that it contacts and wipes the car window while containing some water, thus washing a relatively large area of car window despite using a small amount of water. Furthermore, as shown in FIG. 24, in the case of the skirt-shaped part 930 having a two or more ply structure, the car window is washed more efficiently.

[101] Meanwhile, in FIGS. 23 and 24, the window brush unit 90 has a circular shape, but the present invention is not limited to this. That is, the window brush unit 90 may be formed in a polygonal shape, such as a rectangular shape or a square shape.

[102] Furthermore, in FIGS. 23 and 24, the window brush unit 90 has a structure in which the internal threaded part is formed in the circumferential inner surface of the coupling protrusion 910, but, as shown in FIG. 25, the window brush unit 90 may be configured such that the external threaded part is formed on the circumferential outer surface of the coupling protrusion 910 and is screwed to the coupling part 50.

[103] FIG. 26 is a perspective view of a window brush unit having a skirt-shaped part filled with sponge material.

[104] In the present invention, as shown in FIG. 26, the skirt-shaped part 930 of the window brush unit 90 may be filled with sponge material 990, thereby enabling efficient washing of the car window despite the use of a relatively small amount of water.

[105] FIGS. 27 and 28 are views schematically illustrating methods of coupling a window brush unit to a coupling part of the car window cleaner.

[106] As shown in FIG. 27, a water container is coupled to the internal threaded part 510 of the coupling part 50 of the handle 10, and the water discharge guide plug 610 is press-fitted into the end of the coupling part 50 on which the external threaded part 570 is formed. Subsequently, the window brush unit 90 is coupled to the external threaded part 570 through a threaded engagement. As such, in the case that the water discharge guide plug 610 is fitted into the window brush unit 90, water is prevented from being excessively discharged from the water container, thus saving water.

[107] In addition, when the car window cleaner of the present invention is not in use, as shown in FIG. 27, the plug stopper 630 is press-fitted into the water discharge guide plug 610 to prevent water from leaking.

[108] In FIG. 27, the water discharge guide plug 610 and the plug stopper 630 are provided between the external threaded part 570 of the coupling part 50 and the window brush unit 90, but they may be provided between the water container and the internal threaded part 510 of the coupling part 50.

[109] FIG. 29 is a perspective view showing a plug having a ball valve structure. FIG. 30 is an exploded perspective view showing a sponge member separated from the base plate of the ball valve plug. FIG. 31 is a view showing the mounting structure of the ball valve plug between the window brush unit and the coupling part.

[110] In the present invention, the plug 650, which has the ball valve structure shown in

FIGS. 29 and 30, may be fitted between the window brush unit 90 and the external threaded part 570 of the coupling part 50, as shown in FIG. 31.

[I l l] The ball valve plug 650 includes the base plate 652, through which an opening is formed, and a support 654, which supports a spring 656, an end of which is fastened to the base plate 652. The ball valve plug 650 further includes a ball 658, which is interposed between the spring 656 and the base plate 652, a barrel 651, which has a tube shape and is provided on an upper surface of the base plate 652 so that the support 654 is provided in the barrel 651, and the sponge member 659, which is coupled to a lower surface of the base plate 652.

[112] Preferably, the base plate 652 or an inner edge of the base plate 652, which defines the opening, is made of rubber to enhance the water tightness thereof.

[113] In the case that the window brush unit 90 is used for washing the car window, when outside force is applied to the ball 658, the ball valve plug 650 is opened, so that water is discharged from the water container. Then, the car window is efficiently washed using discharged water. [114] In detail, in the ball valve plug 650, the ball 658 is supported on the base plate 652, such that a portion thereof protrudes outside the base plate 652. Therefore, when the portion of the ball 658 that protrudes outside the base plate 652 is brought into contact with the car window and pushed inwards by outside force, a gap is created between the ball 658 and the inner edge of the base plate 652, which defines the opening, thus allowing water to be discharged through the gap. When the outside force is removed, the ball 658 is brought into watertight contact with the inner edge of the opening of the base plate 652, thus interrupting the discharge of water.

[115] FIG. 32 is a perspective view showing another plug having a ball valve structure.

Unlike the ball valve plug of FIG. 29, in the ball valve plug 650 of FIG. 32, a stop ring 651a is provided at a predetermined position of a barrel 651, but there is no sponge member.

[116] FIG. 33 is a view showing the mounting structure of the ball valve plug of FIG. 32 to the coupling part. As shown in the drawing, the stop ring 651a prevents the plug 650 from undesirably falling into the water container when mounting the plug 650 to the water container. The ball valve plug 650 is fitted into the water container. Thereafter, the water container is screwed to the internal threaded part 510 of the coupling part 50 of the handle 10, such that the ball valve plug 650 protrudes from the external threaded part 570 after passing through the internal threaded part 510. In this state, the window brush unit 90 is screwed to the external threaded part of the coupling part 50 of the handle 10.

[117] FIGS. 34 through 36 are perspective views showing a button type plug.

[118] Referring to the drawings, the button type plug 670 includes a barrel 672 which has an opening in an upper end thereof, and a button member 674, which is axially coupled to the upper end of the barrel 672 and selectively opens or closes the opening.

35 is a top perspective view showing the button type plug in an open state. FIG. 36 is a perspective view showing the bottom of the button type plug in an open state.

[120] In FIGS. 34 through 36, no internal threaded part or external threaded part is formed on the circumferential inner or outer surface of the barrel 672, but, in the present invention, an internal threaded part or an external threaded part may be formed on the circumferential inner or outer surface of the barrel 672, so that the barrel 672 is screwed to the coupling part 50 of the handle 10.

[121] FIG. 37 is a view showing the mounting structure of the button type plug to the coupling part. In this case, the water container is screwed to the internal threaded part 510 of the coupling part 50 of the handle 10. Thereafter, the button type plug 670 is inserted into the coupling part 50 of the handle 10 through the external threaded part 570, such that an end of the button type plug 670 contacts an end of the opening of the water container. In this state, the window brush unit 90 is screwed to the external threaded part 570 of the coupling part 50. Here, to prevent the button type plug 670 from being undesirably removed from the coupling part 50 of the handle 10, it is preferable that they be constructed such that friction occurs between the button type plug 670 and the inner surface of the coupling part 50 of the handle 10.

[122] FIG. 38 is a view schematically showing a stopper to be screwed to the internal threaded part formed on a first end of the coupling part. FIG. 39 is a view schematically showing another stopper to be screwed to the external threaded part formed on a first end of the coupling part.

[123] As shown in FIG. 38, if the car window cleaner of the present invention is not in use in a state in which the water container is coupled to a second end of the coupling part 50, the stopper 682 is preferably screwed to the internal threaded part 510 of the coupling part 50 so as to prevent water from being discharged from the water container.

[124] Furthermore, as shown in FIG. 39, in the case that the external threaded part 570 is formed on the first end of the coupling part 50, the coupling part 50 is closed by the stopper 684 having an internal threaded part.

[125] FIGS. 40 and 41 are views schematically showing cleaning plugs, each of which has a sponge member and is screwed to a first end of the coupling part.

[126] As shown in FIG. 41, in the case that the water container is coupled to a second end of the coupling part 50, the cleaning plug 686, which has an external threaded part on an outer surface of a first end thereof and the sponge member on a second end thereof, may be coupled to the internal threaded part 510 formed on the first end of the coupling part 50, thus preventing water from being excessively discharged from the water container, and enabling more thorough cleaning of the car window.

[127] As shown in FIG. 41, in the case that the external threaded part is formed on the first end of the coupling part 50, the stopper 688, having an internal threaded part on an end thereof, is coupled to the first end of the coupling part 50.

In detail, in the coupling pipe 594a, a stop ring 595, which has a diameter larger than the inner diameter of the through hole 592, is provided at a predetermined position on the circumferential outer surface of the coupling pipe 594a. An internal threaded part 596 is formed on the circumferential inner surface of the first end of the coupling pipe 594a on the side of the stop ring 595 on which the coupling pipe 594a is located, so that the water container is screwed to the coupling pipe 594a through the internal threaded part 596. Furthermore, an external threaded part 597 is formed on the circumferential outer surface of the second end of the coupling pipe 594a. In addition, an opening is formed through an end wall provided on the second end of the coupling pipe 594a, and a spring is provided in the second end of the coupling pipe 594a. As well, a ball is interposed between the opening and the spring.

[135] Furthermore, as shown in FIG. 43, the window brush 90 is screwed to the external threaded part 597 formed on the second end of the coupling pipe 594a.

[136] FIG. 44 is an exploded perspective view showing a further coupling pipe mounted to the through hole of the handle.

[137] In the present invention, in place of the above-mentioned coupling pipe, a coupling pipe 594b having a structure shown in FIG. 44 may be used. That is, in this case, the button type plug of FIG. 34 is integrally coupled to a second end of the coupling pipe.

[138] [Fourth embodiment]

[139] FIG. 45 is a perspective view showing a car window cleaner, according to a fourth embodiment of the present invention. FIG. 46 is an exploded perspective view showing a removable coupling member separated from the car window cleaner.

[140] Unlike the car window cleaner of the second embodiment, in the car window cleaner according to the fourth embodiment, as shown in FIGS. 45 and 46, the coupling part 50 includes a mounting hole 522, which is formed through a first end of a handle 10, a slot 524, which is formed between the mounting hole 522 and an outer edge of the handle 10, and the removable coupling member 526, which is press-fitted into the mounting hole 522 through the slot 524.

[141] Furthermore, a guide groove 527 is formed around an outside edge of the removable coupling member 526 to guide insertion of the removable coupling member 526 into the mounting hole through the slot 524. An opening 528 is formed at a central position through the removable coupling member 526.

[ 142] [Fifth embodiment]

[143] FIG. 47 is a perspective view showing a car window cleaner, according to a fifth embodiment of the present invention. FIG. 48 is an exploded perspective view of a handle of the car window cleaner. FIG. 49 is a view showing a locking member screwed to a reverse conical external threaded part of a length adjustment rod of the handle.

[144] In the car window cleaner according to the fifth embodiment of the present invention, unlike the second embodiment, as shown in FIGS. 47 and 48, the handle 10 includes a grip pipe 150 and a length adjustment rod 130, which is inserted into the grip pipe. A window cleaning part 30 is integrally provided on a first end of the length adjustment rod 130, and the external threaded part 132, having a reverse conical shape, is provided on a second end of the length adjustment rod 130. The handle 10 further includes the locking member 170, which has on a circumferential inner surface thereof an internal threaded part 172 that engages with the external threaded part 132 formed on the second end of the length adjustment rod 130. A longitudinal slit 174 is formed in the locking member 170.

[145] When the grip pipe 150 is rotated in one direction, the locking member 170 is also rotated due to friction between it and the inner surface of the grip pipe 150. The locking member 170 is tightened over the reverse conical external threaded part 132 of the length adjustment rod 130. Then, as the diameter of the locking member 170, which is being tightened over the reverse conical external threaded part 132 of the length adjustment rod 130 by rotation of the grip pipe 150, is gradually increased, the friction between the locking member 170 and the grip pipe 150 also increases. As a result, the grip pipe 150 is securely locked to the length adjustment rod by the locking member 170.

[146] When it is desired to readjust the length of the grip pipe 150, the grip pipe 150 is rotated in the opposite direction, such that the friction between the locking member 170 and the grip pipe 150 is reduced. Thereafter, the grip pipe 150 is moved inwards or outwards along the length adjustment rod 130. Subsequently, the grip pipe 150 is locked to the length adjustment rod 130 by rotating it in the direction in which the locking member 170 is tightened.

[147] Meanwhile, the length adjustable construction of the handle 10 is not limited to this structure.

[148] Thanks to the length adjustable construction of the handle 10, the present invention makes it possible for the user to easily wipe even a portion of the car window which is out of his/her reach.

[154] Furthermore, a locking unit 852, which is selectively inserted between adjacent ring-shaped protrusions 832 of the length adjustment rod 830 to maintain the length adjustment rod 830 at a desired position, is provided on a first end of the grip pipe 850. As well, the grip pipe 850 has at a second end thereof a large diameter part 854, which has an outer diameter larger than the inner diameter of the receiving space of the handle 10. Thus, when the subsidiary cleaning unit 80 is stored in the handle 10, a portion of the large diameter part 854 is inserted into and fastened to the handle 10, and, when it is desired to use the subsidiary cleaning unit 80, the large diameter part 854 makes it possible for the user to easily remove the subsidiary cleaning unit 80 from the handle 10 while holding it. Furthermore, the subsidiary cleaning unit 80 maintains its position in the receiving space using friction generated between the sponge member 810 and the inner surface of the receiving space by the restoring force of the sponge member 810.

[155] As shown in FIG. 53, because the length of the subsidiary cleaning unit 80 is adjustable thanks to the length adjustment rod 830, even if an area covered with dust or snow is far away from the user, the user can easily clean the area.

[156] FIG. 54 is a perspective view showing another subsidiary cleaning unit having a brush member. As shown in FIG. 54, the brush member 812 may be coupled to the subsidiary cleaning unit, unlike the subsidiary cleaning unit of FIG. 52 which has the sponge member 810. In this case, the user may brush away dust in the passenger compartment of the car and remove snow piled on the car using the brush member 812.

[157] As such, in the present invention, because the subsidiary cleaning unit 80, having the sponge member 810 or the brush member 812, is provided in the receiving space of the handle 10, when it is desired to dust the passenger compartment or remove snow from the car window, the user can take the subsidiary cleaning unit 80 out of the handle 10 and easily remove dust or snow from the car using it.
