By the way, dirt on the blades of the blinds is mainly dust and dirt accumulated on the surface. As in the inventions described in Patent Documents 1 and 2, dust is squeezed by a cleaning body and slid in the longitudinal direction. Etc. will be collected on the direction of travel of the cleaning body, but this collected dust will only accumulate on the side of the cleaning body, and even if the cleaning body is pulled out to the front side of the blind, the accumulated dust will remain. Will end up.
SUMMARY OF THE INVENTION In view of such problems, the present invention has an object to allow collected dust to be properly collected after a cleaning body is slid on a blade to collect dust and the like in a cleaning tool dedicated to blinds. And

In order to solve the above problems, the present invention has the following configuration.
The invention according to claim 1 is a member that wipes the surface of the blind by moving along the longitudinal direction of the slats in contact with the upper or lower surface of the slats of the blind, and is separated from the slats in the moving direction. A wiping member having an inclined portion and capable of closing the inclined portion toward the blade plate surface, and in the width direction of the blade plate surface on the opposite side of the inclined portion of the wiping member with respect to the moving direction. A blind cleaning tool having a side damming member made of a waterproof material that abuts against the surface.
The invention according to claim 2 is a member that contacts the upper or lower surface of the blade plate of the blind and wipes off dust by moving along the longitudinal direction of the blade plate, and is inclined to move away from the blade plate in the moving direction. And a tip of the wiping member in a direction parallel to the surface of the blade and perpendicular to the longitudinal direction at the time of contact. A blind having a front damming member made of a waterproof material that comes in contact with the surface of the blade plate with a width equal to or larger than the width of the wiping member in the longitudinal direction of the blade plate when extracted on the base end side. It is a cleaning tool.
According to a third aspect of the present invention, in the blind cleaning tool, the wiping member is rotated by a rotation axis that is perpendicular to the longitudinal direction of the blind blade plate and substantially parallel to the blind blade surface. Thus, the inclined portion can be formed in both directions along the longitudinal direction of the blade, and each of the inclined surfaces formed in both directions can be closed toward the blade plate. Note that “parallel to the blade” means parallel to a plane including both side edges of the blade.
According to a fourth aspect of the present invention, in the blind cleaning tool, the wiping member is provided on both the upper and lower surfaces of the blade plate so as to sandwich the blade plate of the blind.

In the first aspect of the invention, when the wiping member wipes the surface of the blind blade, dust and dirt accumulate between the inclined portion and the blind surface. After that, by closing the inclined portion toward the blade surface, accumulated dust and the like is sandwiched between the blind surface and the inclined portion, so that the wiping member can be removed while making contact with the blade surface. Dust and the like can be collected. Further, by providing the waterproof side damming member, even if moisture such as cleaning liquid is present on the surface of the blade, it can be wiped by being pushed out in the wiping direction by the damming member.
According to the second aspect of the present invention , dust and dirt accumulated between the inclined portion and the blind surface are sandwiched by closing the inclined portion toward the blade plate surface, and the wiping member is used as it is. Dust and the like can be collected by removing it while coming into contact with the plate surface. Further, when the wiping member is pulled out from the blade plate in the direction perpendicular to the longitudinal direction, the pinch between the wiping member and the blade plate is removed. Leaked dust, moisture, etc. can be removed by the front damming member.
In the invention according to claim 3, since the inclined portion can be formed in both directions along the longitudinal direction of the blade, the blade can be wiped in either direction.
The invention according to claim 4 can clean both surfaces of the blade simultaneously by forming wiping members on both upper and lower surfaces.

The front ends of the upper front blocking member 51 and the lower front blocking member 52 are in contact with each other. In this state, the box-shaped body portions of the upper frame 10 and the lower frame 20 are held substantially horizontally.

Next, the usage method of the blind cleaning tool X which has the above structures is demonstrated. First, the user applies cleaning liquid to the blind blades by spraying, and then pushes the lever 11 of the blind cleaning tool X toward the handle 21 to open the upper frame 10 and the lower frame 20, and in this state Hold the edge of one blade. If necessary, the upper guard 12 and the lower guard 22 are set up in a vertical state. Thereby, an operator's hand can be prevented from being injured by the blind blade.
FIG. 4A shows a cross-sectional view illustrating a state in which the blade B is sandwiched. From this state, the lever plate 35 is operated to rotate the upper gear 33 and the lower gear 43 associated therewith to move away from the blade plate B in the direction of wiping the upper wiping member 30 and the lower wiping member 40. Tilt so that. FIG. 4B shows a cross-sectional view illustrating a state in which the upper wiping member 30 and the lower wiping member 40 are inclined. In this state, the upper wiping member 30 and the lower wiping member 40 are each formed with an inclined portion away from the blade plate B in the wiping direction. Further, the front end surface of the rubber plate constituting the upper side damming member 31a located on the opposite side of the inclined portion of the rubber plate portion 31 of the upper wiping member 30 extends substantially in the width direction of the surface of the blind blade. Are formed so as to contact each other. Similarly, the tip surface of the rubber plate constituting the lower side damming member 45 located on the opposite side of the inclined portion of the lower wiping member 40 is also in contact with the width direction of the surface of the blind blade. Is formed.

  In this state, when the blind cleaning tool X is slid in the longitudinal direction of the slats B, dust and dirt on the surface of the slats are caused by the rubber plate 31 of the upper wiping member 30 and the sponge part of the lower wiping member 40. It is wiped off by 41. In addition, since the surface of the blade B is dammed in the width direction by the upper side damming member 31a and the lower side damming member 45, the water such as the cleaning liquid is also damped in the upper side damming member 31a and the lower side. All are wiped off by the blocking member 45. When the blind cleaning tool X is slid to almost the end of the blade B, the lever plate 35 is operated to return the upper wiping unit 30 and the lower wiping member 40 to their original positions. As a result, the upper wiping member 30 and the lower wiping portion 40 are slightly moved in the wiping direction, and the inclined portions formed vertically are closed toward the blades, and the collected dust and dirt are sandwiched therebetween. Then, with the upper frame 10 and the lower frame 20 closed, the blind cleaning tool X is pulled forward. Thereby, the dust and dirt sandwiched between the upper wiping member 30 and the lower wiping member 40 also move, and further, the front damming member 50 is in contact with the blade 50, while the dust and dirt on the surface of the blade B are removed. The cleaning liquid will be wiped off. By the operation as described above, dust and the cleaning liquid on the blades can be almost wiped off. The wiped dust and the cleaning liquid accumulate in the lower frame, which may be cleaned as appropriate. Moreover, although the case where the blades are wiped by sliding in one direction is shown here, if the upper wiping member 30 and the lower wiping member 40 are inclined in the reverse direction, the blades are similarly moved in the reverse direction. Can be wiped off.
