Description

  The present invention relates to a cleaning tool. In particular, the present invention relates to a cleaning tool used for cleaning a screen door or the like.

  In recent years, with the widespread use of automobiles, air pollution in urban areas has become significant. For this reason, in the screen door provided in the window of the home, the clogging of the screen is severe. In other words, the screen doors are clogged with oily components or the like due to the influence of the exhaust gas of the automobile. If the net is clogged, the broken screen door will lose its meaning. Therefore, even at home, the screen doors are often wiped and cleaned.

  Well, it is not easy to say that cleaning the screen door with a bite. This is because if a force is applied during wiping and cleaning, the net will bend easily, and even deposits clogged in the net cannot be removed cleanly.

Therefore, a cleaning tool for screen doors has recently been proposed by one of the applicants of the present application. This screen door cleaning tool includes a gripping portion and a rotating roller attached to an extending portion from the gripping portion, and a wire rod is embedded on the surface of the rotating roller. It is. And when the rotating roller of this cleaning tool is run on the screen surface of the screen door, the wire protruding from the surface of the rotating roller enters the mesh of the mesh, and the adhering matter covering the screen surface by the surface of the rotating roller. It will be removed.
Japanese Utility Model Publication No. 57-35880 Japanese Utility Model Publication No. 62-202382 Japanese Utility Model Publication No. 2-48175 JP 2000-197849 A JP 2002-143754 A

Now, the cleaning tool proposed above makes it very easy to clean the screen door.
However, when the screen door is cleaned, cleaning liquid is applied to the rotating roller. Therefore, the rotating roller contains water, for example. In doing so, it has been found that there is a problem in that the moisture scatters on the face when traveling at a position higher than the face during cleaning.
In view of this, it has been considered to provide a cover so that water splashed during cleaning is not applied.

  By the way, although a use is completely different from a cleaning tool, what provided the cover body to the rotating roller is known. For example, in Japanese Utility Model Laid-Open No. 57-35880, Japanese Utility Model Laid-Open No. 62-202382, Japanese Utility Model Laid-Open No. 2-48175, Japanese Patent Application Laid-Open No. 2000-197849, Japanese Patent Application Laid-Open No. 2002-143754, etc. As an applicator for this purpose, an applicator provided with a rotating roller and a cover body covering the rotating roller has been proposed.

  Therefore, a prototype of this type of applicator with a cover attached to the cleaning tool was manufactured. And I tried to clean the screen door using this.

  That is, when the cleaning of the screen door is attempted using the cleaning tool with the cover body attached as in the above publication, the cover body cannot perform a sufficient function.

  As a result of diligently investigating this cause, it has been found that the application of paint and the cleaning of screen doors have different applications, so that the required functions must also be different. That is, when applying the paint, the cover body must have a fixed posture. This is because if the cover body is not fixed in position, that is, if it fluctuates, the cover body hits the existing paint film surface of the paint, leaving a cover body contact mark on the paint film surface. Even if the paint is applied neatly, it becomes meaningless. Therefore, the cover body is a fixed type in any applicator provided with the cover body. Although there is no difference in the fixed type, there is also proposed one having an adjustment function so that it can be set in several postures (Japanese Patent Laid-Open No. 2000-197849). However, in any proposal, there is no difference that the cover body is fixed at the set position during the coating operation.

  And even if it was a cleaning tool, even if it was a cleaning tool, since it was fixed, the malfunction was caused.

  That is, if the cover body has a fixed posture, even if the screen door can be cleaned without problems at a certain height position, the cover body will be obstructive for cleaning at a higher position. Was not successful.

  Therefore, the problem to be solved by the present invention is to effectively prevent the splashing of water, that is, the cleaning tool that can effectively prevent the splashed water from hitting the face and clean the surface. Is to provide.

  Now, I thought that the cover body would be indispensable to prevent the splashing water from hitting. Then, when cleaning the screen door, as a result of careful examination of the cause of the obstruction of the necessary cover body, it was found that the cover body was fixed.

  Therefore, I tried to make the cover body rotatable. As a result, it was found that the results were better than expected.

The present invention has been achieved based on such knowledge.
That is, the problem is that the gripping unit, the rotating roller attached to the extending part from the gripping part, and the cover that covers the rotating roller attached to the extending part from the gripping part. A cleaning tool comprising a body,
The cover body is solved by a cleaning tool characterized in that the cover body is rotatably attached to the extending portion from the gripping portion.

Specifically, the gripping unit, the rotating roller having a wire protruding on the surface attached to the extending part from the gripping part, and the rotating roller attached to the extending part from the gripping part are covered. A cleaning tool comprising a cover body that
The cover body is solved by a cleaning tool characterized in that the cover body is rotatably attached to the extending portion from the gripping portion.

  In addition, the above cleaning tool is solved by the cleaning tool characterized in that the cover body is provided with a protruding portion that protrudes forward at a position lower than the rotation center position of the cover body. In particular, in the cleaning tool described above, a roller having a rotation center at a position below the rotation center position of the cover body is provided on the cover body, and the roller front end protrudes from the cover body front end. It is solved by a cleaning tool characterized by its size.

  In addition, the cleaning tool described above is solved by the cleaning tool characterized in that the rotation shaft core of the cover body and the rotation shaft core of the rotation roller are arranged on the same line.

  Since the rotatable cover body is provided, for example, when cleaning the screen door, the cleaning can be performed without any trouble without depending on the position of the cleaning portion (height). That is, it is excellent in cleaning workability. And even if water splashes from the rotating roller, the scattered water is received by the cover body, and it can be effectively prevented that the water splashed from the rotating roller hits the face.

  Then, when the cover body is provided with a protruding portion that protrudes forward at a position below the rotation center position of the cover body, for example, a roller having a rotation center at a position below the rotation center position of the cover body When the roller has such a size that the front end of the roller protrudes from the front end of the cover body, the rotating operation of the cover body is performed smoothly during cleaning. That is, if the cover body has an arcuate cross section, the cover body is substantially U-shaped (substantially concave) due to the weight of the cover body. That is, in the normal state (when not cleaning) where the cleaner is only in hand, the lower half of the rotating roller is in a posture covered with the cover body. However, when cleaning, if the cover does not change to a state rotated by approximately 90 °, the cover body interferes with cleaning. This 90 ° rotational operability is greatly improved when the protrusions (rollers) as described above are provided. In particular, when the rotating roller and the roller are in contact with the cleaning surface, the roller is guided by the roller, so that the cleaning workability is very good.

  Further, if the rotation axis of the cover body and the rotation axis of the rotation roller are arranged on the same line, it is convenient that the rotation roller does not interfere with the rotation of the cover body.

  The cleaning tool of the present invention is, for example, a tool for cleaning a screen door screen. And it comprises a gripping part, a rotating roller attached to the extending part from the gripping part, and a cover body covering the rotating roller attached to the extending part from the gripping part. . In particular, this cover body is rotatably mounted. Preferably, the cover body is provided with a protruding portion that protrudes forward in a position below the rotation center position of the cover body. For example, a roller having a rotation center at a position below the rotation center position of the cover body is provided on the cover body. And this roller is a thing of the magnitude | size which the roller front end protrudes from the cover body front end. Further, the rotation axis of the cover body and the rotation axis of the rotation roller are configured to be on the same line. And the wire rod is attached to the rotating roller, and the front-end | tip part of this wire rod protrudes from the surface.

This will be described in more detail below.
FIG. 1 is a perspective view of the cleaning tool according to the first embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes a grip portion of the cleaning tool A. That is, at the time of cleaning, the gripper 1 is used for cleaning (wiping and cleaning).

  Reference numeral 2 denotes an extension part having a predetermined shape extending from the grip part 1. For example, it has a substantially “ma” shape. Such a shape is also well known in the applicators listed in the patent literature.

  Reference numeral 3 denotes a rotating roller. The rotating roller 3 has a bearing hole along its longitudinal direction, and the tip of the extending portion 2 from the grip portion 1 is inserted into the bearing hole. Accordingly, the rotating roller 3 can freely rotate around the tip of the extending portion 2. In addition, since such a rotation structure is also well-known in the said patent document etc., detailed description is abbreviate | omitted. The rotating roller 3 is made of a cloth or nonwoven fabric or other water-resistant and water-containing material. In addition, a large number of wire rods 3a having a protrusion length of about 5 to 10 mm (may have some width) are embedded on the surface of the rotating roller 3.

  4 is a cover body. A cover surface (a portion excluding the frame portion and the left and right wall surfaces) 4a of the cover body 4 is made of a transparent or translucent resin. Of course, it may be opaque, but it is preferable that the rotating roller 3 is made of a transparent or translucent material since it can observe the degree of dirt, moisture content, etc. of the rotating roller 3 during cleaning. The left and right wall surfaces 4b, 4c of the cover body have, for example, a semicircular shape. Accordingly, the cover surface 4a has a semicircular cross section. Of course, it doesn't matter if it is slightly over half a circle.

  In the present embodiment, bearing portions 4 d are formed on the left and right wall surfaces 4 b and 4 c of the cover body 4. The tip of the extending portion 2 from the grip portion 1 is inserted into the bearing portion 4d of the one wall surface 4b, as in the case of the rotating roller 3. The bearing portion 4d is composed of a concave portion formed on the wall surface 4b and an elastic substantially Y-shaped member having a latching convex portion on the inner side of the tip provided on the wall surface 4b. Therefore, the bearing portion 4d can be removed from the extending portion 2. That is, it is a detachable type. Further, the shaft 6 is inserted into the bearing portion of the other wall surface 4c (the through hole formed in the wall surface 4c unlike the structure of the bearing portion 4d), and the tip of the inserted shaft 6 is the bearing of the rotating roller. It fits in the hole. Accordingly, the cover body 4 is attached so as to be freely rotatable with the rotation axis of the rotation roller 3 as the axis.

  Reference numerals 5a, 5b, 5c and 5d denote discs (rollers). The rollers 5a, 5b, 5c and 5d are also attached so as to be rotatable. The rollers 5a and 5b are attached to the wall surface 4b, and the rollers 5c and 5d are attached to the wall surface 4c. The attachment center position (height) of the disks 5 a, 5 b, 5 c, 5 d is a position below the rotation center position of the cover body 4. The lower position means that the disc is in a natural state where the grip 1 of the cleaning tool A is held, that is, in a state where a force other than gravity is not applied (the state shown in FIG. 1). That is, the attachment center position (height) of 5a, 5b, 5c, 5d is a position below the rotation center (extension part 2) position of the cover body 4. The size of the discs 5a, 5b, 5c, 5d is such that, for example, the front ends of the discs 5a, 5c protrude forward from the front end of the cover body 4, and the rear ends of the discs 5b, 5d are rearward of the cover body 4. It is the size which protrudes from the end to the rear side.

  Now, in a state where the grip 1 is held in an attempt to clean the screen door, as shown in FIG. 1, the cover body 4 is in a posture in which the cover surface is concave with its own weight. That is, the opening surface of the cover body 4 faces upward.

  In this state (the opening surface of the cover body 4 is on the upper side), when the cleaning tool A is brought close to the vertical screen surface of the screen door, first, the disks 5a and 5c hit the screen. Then, since this contact position (height) is lower than the height of the rotation axis of the cover body 4, a force that rotates the cover body 4 clockwise from the net acts as can be understood from the principle of action and reaction. To do. That is, as shown in FIG. 2, the opening surface of the cover body 4 rotates from the horizontal direction to the vertical direction so that the cover body 4 covers the rotating roller 3 from behind. Accordingly, the cleaning mode can be entered as it is without difficulty, and even when moisture is scattered from the rotating roller 3 during cleaning, water is not scattered on the face because it is covered by the cover body 4.

  As described above, the main feature of cleaning the vertical surface is as described above, but it is also effective for cleaning the horizontal ceiling surface. For cleaning the horizontal ceiling surface, the cleaning tool A is approached from the bottom toward the ceiling. At this time, even if the cover body 4 is rotatable, the opening surface of the cover body 4 always faces upward due to its own weight. Therefore, even if the rotating roller 3 contains water and the water drops from the rotating roller 3, the dropped water is received by the cover body 4 and does not hit the face or fall to the floor. Therefore, a curing (preliminary) operation such as cleaning the ceiling surface after laying a sheet on the floor in advance is unnecessary, which is very simple.

  If the cover body 4 is detachable, the cover body 4 can be removed when the rotating roller is immersed in the cleaning liquid (medicine), which is very convenient. Of course, a structure that can move to a position away from the position of the rotary roller 3 as well as the complete removal is also possible.

FIG. 3 is an explanatory diagram of a cleaning tool according to the second embodiment of the present invention.
The basic structure of the cleaning tool B of this embodiment is the same as that of the cleaning tool of the above embodiment.
However, in the cleaning tool A of the embodiment, the rotating roller 3 and the cover body 4 are rotatably mounted on the same shaft, whereas the cleaning tool B of the present embodiment is mounted with the rotating roller 3. The difference is that it is attached to a member different from the shaft.

  That is, the cover body 4 is rotatably attached to the second extending portion 11 from the grip portion 1 (extending portion 2). That is, the distal end portion 11a of the extending portion 11 can move along the guide groove portion 12 in the circumferential direction. This rotatable mounting mechanism is like a planetary mechanism as can be seen from FIG. In addition, since such an attachment mechanism is also well-known as an attachment method, detailed description is abbreviate | omitted. However, if the extending portion 2 to which the rotating roller 3 is attached and the extending portion 11 to which the cover body 4 is attached are separate members, the rotating roller 3 is placed in a chemical such as a cleaning liquid, although the mechanism is complicated. In the case of soaking, it is possible to easily remove the extending portion 11 from the extending portion 2 (cancel the fitting state of both), and to prevent the cover body 4 from being soaked in a chemical such as a cleaning solution. Is advantageous.
