Description

  The present invention relates to a water droplet wiping tool used when wiping off water droplets adhering to the surface of a vehicle body.

  The water droplet wiping tool is used, for example, when wiping off water droplets adhering to the surface of the vehicle body after car washing, and water absorption capable of wiping off a large amount of water droplets is required. A water droplet wiping tool (a water droplet wiping device for car wash) disclosed in Patent Document 1 has a configuration in which a cylindrical water-absorbing sponge is rotatably attached (Patent Document 1 and [Claim 1]). As a specific example, a structure in which a synthetic wiping cloth formed in a rectangular shape is attached to a rotatable roller (Patent Document 1, [0009] [FIG. 2]). Moreover, the water droplet wiping tool (car roof cleaning tool) disclosed in Patent Document 2 has a configuration in which a towel cloth is rounded while a large number of ridges are formed, and a rope is inserted through the center of the rolled towel cloth. There is a usage example in which one end of a rope that spans the roof of the vehicle body is fixed, and the other end is shaken back and forth to rub the towel fabric against the roof and blow up water droplets (Patent Document 2 [Use state reference diagram) 3]).

JP 09-295559 A Design Registration No. 1210366

  The water drop wiping tool disclosed in Patent Document 1 or Patent Document 2 is preferable in that it increases the surface area of a towel cloth formed with a large number of synthetic wiping cloths and ridges formed in a rectangular shape so that a large amount of water drops can be wiped off. . However, there are problems in specific configurations. The water droplet wiping tool disclosed in Patent Document 1 has a problem in that it takes time and effort for manufacturing because the synthetic wiping cloth formed in a rectangular shape is attached to a rotatable roller one by one. Moreover, since the synthetic | combination wiping cloth attached to the roller one by one is attached to the roller independently one by one, each has the problem that it is easy to separate, ie, it is easy to break.

  Since the water drop wiping tool disclosed in Patent Document 2 increases the surface area by forming a crease on one towel cloth, the problem is that individual synthetic wiping cloths are separated and broken like the water drop wiping tool disclosed in Patent Document 1. There is no. Here, it is not clear how the folds are formed, but as far as the enlarged folds are seen, it seems that the roots of the folds are sewn along the extending direction of the toweling. . The method of forming a crease on a toweling fabric by sewing is the simplest method, but it is impossible to deny the possibility that the sewing thread will loosen by squeezing the absorbed water. There is a problem.

  Thus, the water droplet wiping tool disclosed in Patent Document 1 or Patent Document 2 has a problem of poor durability in a specific configuration. Therefore, with reference to Patent Document 2, a water wiping tool capable of wiping a large amount of water droplets by folding a single water-absorbing cloth to form a large number of ridges and increasing the surface area will be developed. In order to solve the problem that the cocoon collapses, we studied how to make the cocoon.

  What was developed as a result of the study was a cylindrical water-absorbing cloth in which the extending direction was aligned and rounded in the direction in which a large number of ridges were arranged to form a hollow part, and a mandrel that could be freely inserted into and removed from the hollow part of the water-absorbing cloth The water-absorbing cloth is a water droplet wiping tool in which wrinkles are formed in a slackened portion by passing through a restraining belt slightly longer than the outer peripheral length of the mandrel and closing the restraining belt in an annular shape. The water droplet wiping tool of the present invention is not formed by sewing each heel at the root while forming a heel by folding a water-absorbing cloth, as in Patent Document 2, but by using a restraining belt that is inserted and removed. By closing in an annular shape, a wrinkle is formed at the loosened portion. The restraining belt is hidden through the interior of each ridge and exposed at the valley between adjacent ridges. The portion where the restraint belt is exposed becomes a valley between adjacent ridges.

  The water-absorbent cloth is not limited to a specific material and the like as long as it is a cloth having a water-absorbing function. For example, as shown in Patent Document 2, towel cloth may be used. The restraint belt is "slightly longer than the outer perimeter of the mandrel" means that the perimeter of the restraint belt closed by connecting both ends is longer than the outer perimeter of the mandrel (outer circumference), but the restraint belt is closed in an annular shape. It means that it is limited to such a length that the valley between the ribs is touched with the outer peripheral surface of the mandrel. The restraint belt is not limited as long as it is water resistant and does not stretch. The mandrel is a member that determines the overall shape of the water-absorbing cloth with a heel. The water absorbent cloth has a linear or curved overall shape according to the shape of the mandrel inserted into the hollow portion.

  In the water absorbent cloth, when a plurality of restraint belts slightly longer than the outer peripheral length of the mandrel are arranged at intervals in the extending direction of the heel, a plurality of heel roots restrained by the restraining belt can be formed in the extending direction of the heel. Thus, the hollow portion into which the mandrel is inserted can be secured within the range where the restraint belt is disposed. Thus, it is preferable that there are at least three constraining belts that secure the hollow portion at both ends and an intermediate position in the extending direction of the flange. When four or more restraining belts are arranged, a plurality of restraining belts at intermediate positions among the three restraining belts may be provided. In this case, it is desirable that the plurality of restraining belts arranged at the intermediate positions are equidistant from the restraining belts arranged at both ends in the extending direction of the heel or between the adjacent restraining belts.

  The water-absorbing cloth is arranged with a pair of restraining belts at least at both ends in the extending direction of the heel, and while one restraining belt is slightly longer than the outer peripheral length of the mandrel, the other restraining belt is used as the outer peripheral length of the mandrel. The same or slightly shorter. As a result, when the mandrel is inserted into the hollow portion from the side where the restraint belt slightly longer than the outer circumference of the mandrel is placed, the mandrel is caught by the restraint belt that is the same or slightly shorter than the outer circumference of the mandrel, and from the opposite side of the inserted side. You will never get out. There may be at least two restraining belts for preventing the mandrel from coming out at both ends in the extending direction of the flange, but as described above, from the viewpoint of securing the hollow portion, the three restraining belts should be added with an intermediate position. preferable.

  The mandrel may be a material that is water-resistant and does not stretch, and may be solid or hollow. In addition, the mandrel may have a circular or square cross-sectional shape as long as the mandrel has a rod outer shape that specifies the entire shape of the water-absorbing cloth as a normal state, and may further have flexibility or elasticity as a whole. Thus, although the material and structure of the mandrel are free, a preferred mandrel is a cylindrical body composed of a mesh peripheral surface communicating with the inside and outside. The cylinder may be hollow, or may be filled solidly with a water absorbing member (for example, sponge). As a result, water droplets wiped off by the water-absorbing cloth can be drained into the inside of the other cylinder body or absorbed by the water-absorbing member filled in the inside, thereby suppressing or preventing deterioration in water absorption of the water-absorbing cloth. . Moreover, since it is a cylinder which consists of a mesh surrounding surface, it can be reduced in weight. In this case, moderate flexibility and elasticity can be provided if the mesh peripheral surface of the mandrel is made of resin.

  The water droplet wiping tool of the present invention is formed by using a restraining belt that is inserted into and removed from the water-absorbing cloth and closed in an annular shape, so that the problem that the sewing thread frays and the wrinkles are broken does not occur. If the restraint belt has sufficient water resistance, it is possible to suppress deterioration over time, and if it has a sufficient width, it is easy to avoid physical breakage, so that there is no problem that the wrinkles collapse. In this way, the water droplet wiping tool of the present invention has durability and an effect that can be used over a long period of time.

  The water-absorbing cloth in which a plurality of restraining belts are arranged at intervals in the extending direction of the heel secures a hollow portion into which the mandrel is inserted, and there are a plurality of parts that restrain the water-absorbing cloth with respect to the mandrel. On the other hand, it becomes possible to install it stably. This suppresses the mandrel from slipping out of the water-absorbent cloth during the wiping operation. Also, a water absorbent cloth in which one of the restraining belts arranged at both ends in the extending direction of the rod is slightly longer than the outer peripheral length of the mandrel while the other is the same as or slightly shorter than the outer peripheral length of the mandrel, It is possible to prevent the mandrel from slipping out of the water-absorbent cloth during the wiping operation.

  The mandrel is a cylinder made of a mesh peripheral surface that communicates with the inside and outside of the mandrel, so that it is possible to suppress or prevent the water absorption of the water absorbent cloth from wiping off water drops from deteriorating, and the continuous use time of the water drop wiping tool can be reduced. Can be improved. Moreover, since a cylindrical body can be reduced in weight with respect to the water-absorbing cloth that absorbs water droplets and becomes heavier, an advantage of reducing labor for wiping work can be obtained. Furthermore, if the mesh peripheral surface is made of resin, it can have moderate flexibility and elasticity due to the synergistic effect of the material and structure, making it easier to follow the water-absorbing cloth on the surface of a complex automobile. Therefore, the effect of making the wiping work more efficient can be obtained.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the water droplet wiping tool 1 of the present invention is an arrangement direction of 14 ridges 111 aligned in the extending direction (upper left to lower right in FIG. 1, left and right in FIG. 2). A cylindrical water-absorbing cloth 11 that is rounded into a hollow part 112 and a mandrel 14 that can be inserted into and removed from the hollow part 112 of the water-absorbing cloth 11. The 13 ridges 111 are formed by folding the water-absorbing cloth 11, and the last one ridge 111 is formed in a plate shape by overlapping one end portion 116a and the other end portion 116b of the water-absorbing cloth. Yes.

  The water absorbent cloth 11 includes seven restraint belts 12 slightly longer than the outer peripheral length of the mandrel 14 and one restraint belt 13 slightly shorter than the outer peripheral length of the mandrel 14 at equal intervals in the extending direction of the flange 111. A slackened portion is formed as a flange 111 by inserting and removing it through a set of through slits 113a and 113b provided, connecting both ends of the restraining belts 12 and 13 and closing them in an annular shape. The water absorbent cloth 11 of this example is formed by a constraining belt 12 and 13 by inserting a mandrel 14 into a hollow portion 112 surrounded by a virtual inner peripheral surface that follows a valley 115 formed between each ridge 111. The ridges 111 are arranged at equal intervals along the outer peripheral surface of the mandrel 14. The water-absorbent cloth 11 is a water-absorbent fabric knitted with resin ultra-fine fibers and is flexible. The restraining belts 12 and 13 are resin tapes, and both can be fused.

  Seven restraint belts 12 slightly longer than the outer peripheral length of the mandrel 14 are assigned from the right end side (lower right side in FIGS. 1 and 3, right side in FIG. 2) of the hollow portion 112, as seen in FIG. 4. A virtual inner peripheral surface that follows the valley 115 formed between the flanges 111 is formed to such an extent that the insertion and removal of the mandrel 14 inserted into the hollow portion 112 is not hindered. On the other hand, the restraint belt 12 (refer to the dimension line in FIG. 6 to be described later) slightly shorter than the outer peripheral length of the mandrel 14 is on the left end side of the hollow portion 112 (upper left in FIGS. 1 and 3 and left in FIG. 2). As shown in FIG. 5, the virtual inner peripheral surface following the valley 115 formed between the flanges 111 is narrowed so that the mandrel 14 inserted into the hollow portion 112 is engaged, as seen in FIG. Yes. As a result, the water absorbent cloth 11 forms a left-right asymmetric hollow portion 112 with a uniform inner diameter from the right end to the left end, but slightly narrowed only at the left end, and the mandrel is inserted into the left end side when inserted from the right end side of the hollow portion 112. It is caught by the restraining belt 13 and cannot be pulled out from the left end side.

  Further, since the mandrel 14 of this example is shorter than the length of the water absorbent cloth 11 in the direction in which the mandrel 14 is inserted, when the mandrel 14 is inserted into the hollow portion 112, it cannot be seen from the outside. The mandrel 14 in this example has a structure in which a sponge having water absorption is built in a cylindrical body made of a resin mesh with elasticity, and there is no risk of damage even if it hits the surface of a car body. The water absorption of 14 itself is low only by the sponge. As described above, since the mandrel 14 is hidden by the water-absorbing cloth 11, only the water-absorbing cloth 11 hits the surface of the vehicle body in the wiping work, and the water-absorbing cloth exhibits a high water-absorbing ability, so that an efficient wiping work can be performed. .

  The ridge 111 of the water absorbent cloth 11 is formed as follows. First, a long water-absorbing cloth 11 is prepared on the side orthogonal to the extending direction of the flange 111, and as shown in FIG. 6, a pair of through slits 113a and 113b is paired, and the restraining belts 12 and 13 are inserted in the insertion / removal direction. For each row, the set is provided in the longitudinal direction of the water absorbent cloth 11 at regular intervals. The penetration slit 113a (penetration slit 113b) is close to the counterpart penetration slit 113b (penetration slit 113a), but is separated from an adjacent set of penetration slit 113b (penetration slit 113a). A portion where the set of the through slits 113a and 113b is provided is a valley 115, and a portion of the adjacent set of the through slits 113a and 113b is a flange 111. This means that the restraining belts 12 and 13 are exposed only at the valley 115 sandwiched between the ridges 111. Usually, since the valley 115 is hidden by the ridge 111, the exposed restraint belts 12 and 13 are difficult to die from the outside.

  The restraining belts 12 and 13 are exposed across the adjacent sets of through slits 113a and 113b, but are hidden between the set of through slits 113a and 113b. At this time, if the exposed length of the restraining belts 12 and 13 spanning the adjacent sets of through slits 113a and 113b is shorter than the interval between the adjacent sets of through slits 113a and 113b, the adjacent set of through slits The water-absorbing cloth 11 between 113a and 113b is folded, and a ridge 111 is formed as seen in FIG. In each illustration of this example, the length of the restraining belts 12 and 13 exposed between adjacent pairs of through slits 113a and 113b, and the length of the restraining belts 12 and 13 hidden between the pair of through slits 113a and 113b. Are approximately equal, but they may be different. Further, the length of the restraining belts 12 and 13 exposed between adjacent sets of the through slits 113a and 113b and the length of the restraining belts 12 and 13 hidden between the set of through slits 113a and 113b are equal to each other in the circumferential direction. It may not be an interval.

  In this way, the restraining belts 12 and 13 that are inserted and removed for each row in which a large number of through slits 113a and 113b are arranged have ends at the fused portions 114 and 114 set at the one end 116a and the other end 116b of the water absorbent cloth 11. It is fused and integrated with the water absorbent cloth 11. At this time, the one end portion 116a and the other end portion 116b of the water absorbent cloth 11 are overlapped, and the end portions of the restraining belts 12 and 13 are fused, and at the same time, the one end portion 116a and the other end portion 116b are fused. By merging, the final ridge 111 is formed. The fusion of the one end 116a and the other end 116b of the water absorbent cloth 11 may be separate from the fusion of the restraining belts 12 and 13. Further, the water absorbent cloth 11 may be formed into an annular shape by directly fusing the restraining belts 12 and 13 penetrating the one end portion 116a and the other end portion 116b.

  The water droplet wiping tool 1 of this example wipes the water droplet 21 by bringing the hook 111 of the water-absorbent cloth 11 into sliding contact with the surface of the vehicle 2 having the water droplet 21. Since the water absorbent cloth 11 is flexible and the ridge 111 is deformed following the surface of the vehicle body to be slidably contacted, the water droplet wiping tool 1 can absorb water even if it is reciprocated linearly or reciprocated in an arc shape. There is no change in sex. Further, since the water-absorbent cloth 11 is soft, water droplets adhering to the surface of the window glass as well as the surface of the vehicle body that is a steel plate or a resin plate can be wiped off. Thus, the water droplet wiping tool of the present invention can equally wipe off all the water droplets on the vehicle body surface of the automobile 2 including the window glass, using the bag 111 formed by the restraining belts 12 and 13. As a result, the wiping operation with water droplets becomes efficient.
