Japanese Patent No. 5144598

  However, as a result of many years of research and experiments by the inventors of the present application, the above-described cleaning tool has no problem in terms of efficiently removing dirt, and the lower part of the belt-like body 3 that increases the number of times of contact with the tunnel wall surface wears over time. However, as shown in FIG. 5 (b), the range for removing dirt on the wall surface is narrowed and the cleaning efficiency is reduced. In this respect, it was found that there was room for improvement.

  This invention considers the said situation, and the solution subject is providing the cleaning tool which does not get entangled when the strip | belt shaped body which removes the dirt of wall surfaces, such as a tunnel, rotates, and cleaning efficiency does not fall.

The present invention for solving the above-mentioned problems is a cleaning tool in which a belt-like body for wiping off a wall surface is suspended on a support plate fixed to the wall surface of a tunnel or the like, and the belt-like body is in a lower end direction. It is formed in a divergent shape toward the end, and has a core along the longitudinal direction . In addition, the belt-like body here means that it swings or rotates when it receives wind pressure, rubbing against the wall surface such as a tunnel at this time, and wiping off the dirt adhering to the wall surface. Examples include belt-like cloth.

In addition, as long as the core can give rigidity to the strip, there is no problem, but in particular, it does not rub against the surface of the strip, in other words, the wall surface of a tunnel or the like. It is desirable to form the core by applying a resin to the side.

  In addition, as a method of suspending the belt-like body on the support plate, there is no problem even if the belt-like body is directly fixed to the support plate or suspended via a clasp, but the belt-like body is pivotally supported by a pin. It is desirable that the portion pivoted by is folded twice.

  Further, in order for the belt-like body to further rotate along the wall surface of the tunnel or the like, a ball with a pin through hole is arranged outside the belt-like body and is supported by the pin together with the belt-like body. It is desirable that the pin is provided with a detachable pin cap so that the belt can be easily replaced when the belt is broken.

  As in the present invention, if the band-shaped body is formed so as to expand toward the lower end, the area receiving wind is larger, so that the band-shaped body is obtained by obtaining further wind pressure energy than the conventional one. It is possible to increase the rotational force of the belt, and it is difficult to entangle the belt-like body during the rotation.

  Further, if the belt-like body has a core along the longitudinal direction, the belt-like body can have rigidity, so that the possibility of being entangled markedly becomes lower than that of the conventional one.

It is a perspective view which shows the 1st example of the cleaning tool by this invention. It is a perspective view which shows the 2nd example of the cleaning tool by this invention. (A), (b) is a side view which shows the 3rd example of the cleaning tool by this invention, Comprising: It is a side view which shows the removal | desorption state of the pin cap to a pin. It is a side view which shows the 4th example of the cleaning tool by this invention. (A), (B) is a perspective view showing a conventional cleaning tool, (B) shows the cleaning tool immediately after installation on the inner wall surface of the tunnel, and (B) is entangled when the belt-like body rotates. It is a perspective view which shows the cleaning tool of the state which has gone.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. First, as shown in FIG. 1, the first example of the cleaning tool of the present invention includes a support plate 1, a double-sided pressure-sensitive adhesive tape 2, a belt-like body 3, and pins 4.

  The support plate 1 is for suspending the belt-like body 3, and in the first example of the cleaning tool of the present invention, one end portion of the pin 4 penetrates and is fixed. The support plate 1 preferably has a thickness of 1 mm or less, thereby reducing the weight and reducing the gap between the wall surface in the tunnel and the cleaning tool as much as possible. The weight reduction of the support plate 1 has an effect of strengthening the adhesion between the support plate 1 and the wall surface in the tunnel, and has the effect of hardly damaging a car or the like even if it is peeled off. In addition, the small gap between the wall surface in the tunnel and the cleaning tool has an effect that the strip 3 is easily in contact with the wall surface.

  And it is desirable for the support plate 1 to have lubricity in the surface which contact | connects the strip | belt-shaped body 3, and an acrylic board is suitable. The acrylic plate is excellent in self-lubricating properties, can be reduced in weight, and has weather resistance. In addition, the weather resistance used here refers to a property that hardly causes alteration such as deformation, discoloration, and deterioration with respect to wind and rain, temperature change, and the like. In addition, an acrylic plate having a thickness of 1 mm or less can be easily cut with a scissors or the like, so that processing is easy and convenience is high.

  The double-sided pressure-sensitive adhesive tape 2 is for fixing the support plate 1 to the wall surface in the tunnel, and like the support plate 1, it is preferably 1 mm or less in thickness and waterproof.

  When the belt 3 receives wind pressure, it swings or rotates around the pin 4 as an axis, and at this time, it rubs against the wall surface in the tunnel and wipes off the dirt adhering to the wall surface. As shown in FIG. 1, it is formed in a shape that spreads toward the lower end and has a function of preventing entanglement during rotation. The length of the strip 3 in the longitudinal direction is usually about 60 cm, and the strip 3 swings or rotates while drawing a circular orbit with the length as a radius. It should be noted that if the length in the longitudinal direction is short to some extent, it tends to swing and rotate more easily, and a length of about 30 cm can perform the most efficient cleaning. The width of the strip 3 is preferably within several centimeters, the width of the upper end in the longitudinal direction of the strip 3 is about 1 cm, and the width of the lower end in the longitudinal direction is about 2 of the width of the upper end. It is desirable that the width is about 2 cm, and it is desirable that the width gradually increases from the upper end to the lower end. If it is this extent, even if the strip | belt-shaped body 3 tears and scatters, it will not disturb the visual field of the driver | operator of a motor vehicle. The fabric of the strip 3 shown in the figure is preferably a fray-resistant fabric created by forming a continuous loop called a tricot in the warp direction, but is not limited to this. Further, the types of natural fibers, regenerated fibers, and synthetic fibers are not particularly limited with respect to the material of the fibers.

  Further, as in the second example of the cleaning tool of the present invention shown in FIG. 2, the belt-like body 3 preferably has a core 3 a along the longitudinal direction from the viewpoint of preventing entanglement, and at least below the belt-like body 3. It is preferable to have the core 3a half along the center in the longitudinal direction. It should be noted that the core 3a may be any material as long as the belt 3 can be rigid enough not to be entangled even when rotated by wind pressure. For example, the surface of the belt 3, in other words, a tunnel, etc. The core 3a may be formed by applying resin to the side that does not rub against the wall surface, or the core 3a may be formed by sewing with a sewing machine along the longitudinal direction of at least the lower half of the belt-like body 3. In the case where the core 3a is formed by applying a thermoplastic resin on the surface of the band-like body 3, in other words, on the side that does not rub against the wall surface of a tunnel or the like, after confirming the rotation state and cleaning state of the band-like body 3 It is preferable because the rigidity can be easily adjusted. The belt-like body 3 is pivotally supported by the support plate 1 by the pins 4. However, at the portion where the belt-like support is supported, in other words, at the position where the support plate 1 and the belt-like body 3 are in contact with each other, It is desirable that it be folded up heavily. As a result, the belt-like body 3 is difficult to twist and can stabilize the rotation axis.

  In addition, as for the pin 4 shown to the 1st example of the cleaning tool of this invention, and a 2nd example, one end part penetrates the support plate 1, and is fixed, Comprising: The strip | belt-shaped body 3 is pivotally supported. It is. The pin 4 is desirably a linear pin called a tag pin and having both ends formed in a T shape and is elastically deformable. If it is a tag pin, you will usually hit it with a tag gun, but simply pass the tag gun needle through the two (sometimes two or more) you want to connect the tag gun and pull the tag gun trigger. Since the objects to be connected to each other are connected to each other, the creation of the cleaning tool can be simplified. As a method of suspending the belt-like body 3 from the support plate 1, a method using the pins 4 as described above may be used. However, the belt-like body 3 is directly fixed to the support plate 1 or suspended via a clasp. There is no problem with the method, and there is no problem with the following third and fourth examples.

  As shown in FIGS. 3 (a) and 3 (b), the third example of the cleaning tool of the present invention, as in the first example and the second example, is supported by the pin 4 with the pin 4, The part pivotally supported by the pin 4 is folded twice. However, unlike the first example and the second example, the pin 4 is erected in the center of the support plate 1 and is engaged within the paired pin cap 6. The part has an engaging part that can be freely engaged and disengaged, for example, an annular projecting part.

  The pin cap 6 has a conventional general shape and a bottomed shape, and has an insertion portion into which the pin 4 can be inserted, and an end portion in a direction opposite to the insertion portion so that the pin cap 6 can be easily grasped. And has a space that can accommodate at least the tip of the pin 4 in the insertion portion, and can be engaged with and disengaged from the engaging portion of the pin 4. Has a part. The material of the pin cap 6 is desirably self-lubricating and elastically deformable, such as plastic, including the engaged portion, so that the material of the pin cap 6 is hard to break even if it is detached and attached multiple times. When the pin cap 6 is used, as shown in FIG. 3 (a), the belt 3 is first penetrated and pivotally supported by the pin 4, and then, as shown in FIG. 3 (b), the pin cap 6 is used. 6 is fitted. With such a configuration, even when the belt-like body 3 is damaged, the belt-like body 3 can be replaced simply by removing the pin cap 6, so that convenience is high.

  When the pin cap 6 is externally fitted, it is desirable that the end surface of the pin cap 6 on the side of the insertion portion is not in contact with the band-like body 3 so that the belt-like body 3 rotates smoothly. It is desirable that it is shallower than the pin 4. In addition, it is desirable that the engaged portion has a shape in which the pin cap 6 cannot be easily detached from the pin 4, for example, a return structure that is generally provided with a fishhook or an arrowhead that is generally used conventionally. It is desirable to have a simulated shape.

  And the 4th example of the cleaning tool of this invention is comprised by the support plate 1, the double-sided adhesive tape 2, the strip | belt-shaped body 3, the pin 4, and the ball 5, as shown in FIG.

  The ball 5 is arranged outside the belt-like body 3, in other words, on the side opposite to the support plate 1, and is pivotally supported on the support plate 1 by the pins 4 together with the belt-like body 3. The ball 5 has a hole for allowing the pin 4 to pass therethrough. For example, a so-called bead which is a small decorative ball having a threading hole is desirable. And this ball | bowl 5 gives the soft pressing with a large area to the strip | belt-shaped body 3, The strip | belt-shaped body 3 can rotate smoothly, sticking to the wall surface in a tunnel.

  Although the outer shape of the ball 5 is not particularly limited, it is desirable that the ball 5 is rounded so that the strip 3 is not caught and has a smoothness. As a result, the belt-like body 3 is further easily rocked or rotated.

  The cleaning method of the wall surface in the tunnel using the cleaning tool of the present invention described above is as follows. First, a large number of cleaning tools are bonded to the wall surface in the tunnel at equal intervals, or more specifically to the interior board. Then, when the automobile passes through the tunnel, the belt-like body 3 suspended from the support plate 1 swings or rotates about the pin 4 as a rotation axis by the wind pressure. At this time, the belt-like body 3 is lightly pressed against the wall surface by the wind pressure while rotating, so that the dirt adhering to the wall surface can be wiped off. At this time, the cleaning tool of the present invention is not easily entangled by the above-described configuration, so that the cleaning efficiency is not lowered.

  In addition, the cleaning tool of this invention is not limited to the said embodiment, For example, without using the double-sided adhesive tape 2, even if it fixes the support plate 1 to a wall surface directly with an adhesive agent etc., there is no problem. Moreover, although the cleaning tool of this invention is mainly used for the cleaning of the wall surface in a tunnel, you may use it for cleaning wall surfaces, windows, etc., such as a house.
