  The head 1 has a block shape extending in the longitudinal direction of the wiper blade 3 as a whole, and is composed of a first head portion 1a and a second head portion 1b that can be divided into two along the longitudinal direction. Each of the first head portion 1a and the second head portion 1b is integrally formed of a resin having a predetermined strength such as an ABS resin.

  Concave portions 11 and 12 are formed on the inner walls of the first head portion 1a and the second head portion 1b so as to face each other along the longitudinal direction. By wiping the wiper blade 3 between the first head portion 1a and the second head portion 1b so that the bulging portion 31 of the wiper blade 3 is surrounded by the recesses 11 and 12, the wiper blade 3 is attached to the head 1. Installed. On the first head portion 1a and the second head portion 1b, flange portions 13 and 14 are formed so as to oppose each other along the longitudinal direction at an appropriate position separated from the concave portions 11 and 12. The sponge body 4 is attached to the head 1 by sandwiching the attachment portion 41 of the sponge body 4 between the flange portions 13 and 14. A plurality of pointed locking projections 13a facing the flange 14 side are formed on the flange 13 at a predetermined pitch along the longitudinal direction, and the sponge body 4 is separated from the head 1 by the locking projection 13a. It is prevented from falling off.

  As clearly shown in FIG. 3, a plurality of engagement cylinders 15 and engagement shafts 16 are provided at appropriate positions on the inner walls of the first head portion 1a and the second head portion 1b. The first head portion 1a and the second head portion 1b are integrally connected by inserting the engagement shafts 16 into the engagement cylinders 15 and fastening them with screws 17 or the like.

  As shown in FIGS. 2 to 4, the head holder 2 includes a pair of shaft portions 21 that are fitted into through holes 52 of the guide body 5 to be described later, a handle portion 22 for connecting the handle, and a lock. And an engaging portion 23 constituting the mechanism L. The head holder 2 is integrally formed of a resin having a predetermined strength such as an ABS resin.

  The pair of shaft portions 21 are formed on one end side in the longitudinal direction of the head holder 2. The center of each shaft portion 21 coincides with a predetermined axis that is perpendicular to the longitudinal direction of the head holder 2. The outer diameter of each shaft portion 21 is slightly smaller than the inner diameter of the through hole 52. The handle 22 is formed to extend to the other end in the longitudinal direction of the head holder 2 and has a cylindrical inner surface having an inner diameter equivalent to the outer diameter of the rod-like handle 6. The handle 6 is fitted to the handle portion 22 and connected to the head holder 2. The engaging portion 23 has a concave engaging step portion 23a that can be engaged with an engaging convex portion 71 formed on the operation lever 7 described later.

And a concave portion (not shown). The guide body 5 is integrally formed of a resin having a predetermined elasticity.

  The operating lever 7 has an engaging convex portion 71, a locking piece 72 for locking to the second head portion 1b, and a pair of convex portions (not shown) for positioning with respect to the guide body 5. . The operation lever 7 is integrally formed of a resin having a predetermined elasticity.

  When the head holder 2 is connected to the head 1, the locking piece 53 of the guide body 5 is formed on the outer peripheral surface of the second head portion 1 b with the pair of guide bodies 5 sandwiching the head holder 2 and the operation lever 7. This can be done by inserting it into the opening. More specifically, the pair of shaft portions 21 of the head holder 2 are fitted into the through holes 52 of the pair of guide bodies 5, and the pair of projections of the operating lever 7 are fitted into the recesses of the guide body 5. If the guide body 5, the head holder 2 and the operating lever 7 are inserted through the opening of the second head portion 1b while being positioned, the locking piece 53 of the guide body 5 and the locking piece 72 of the operating lever 7 are elastically deformed. And it is latched by the latching | locking parts 18 and 19 formed in the 2nd head part 1b. Thereby, the pair of guide bodies 5 and the operation lever 7 are integrally fixed to the head 1.

  Here, the guide portion 51 of the guide body 5 is provided so as to extend from the head 1 in a cantilever manner. Further, as shown in FIG. 7, in the state where the guide portion 51 is in contact with the glass surface S together with the wiper blade 3, the contact portion 51 a with the glass surface S of the guide portion 51 protrudes toward the glass surface S. In addition to the curved shape, the contact portion 51a and the contact portion 3a with respect to the glass surface S of the wiper blade 3 have a relatively large predetermined distance. In the state shown in FIG. 7, the contact portion 51 a is located on the head holder 2 side with respect to the wiper blade 3. In this state, when the head 1 is pressed against the glass surface S with a predetermined pressing force, the guide portion 51 is elastically deformed and is in a state indicated by a dotted line in FIG.

  As described above, since the outer diameter of the shaft portion 21 of the head holder 2 is slightly smaller than the inner diameter of the through hole 52 of the guide body 5, the head holder 2 and the pair of guide bodies 5 are a pair of Relative rotation is possible around the shaft 21. Further, since the pair of guide bodies 5 are integrally fixed to the head 1, the head 1 rotates with respect to the head holder 2 around a pair of shaft portions 21 parallel to the longitudinal direction of the head 1. It becomes possible.

  The lock mechanism L is for restricting and locking the rotation of the head 1 with respect to the head holder 2, and as shown in FIG. 3, an opening is formed at an appropriate position of the operation lever 7 and the head holder 2. It is comprised from the engaging part 23 provided as. When the operating lever 7 is pressed toward the engaging portion 23, the operating lever 7 is elastically deformed, and the engaging convex portion 71 of the operating lever 7 is engaged with the engaging step portion 23 a of the head holder 2. Here, since the operation lever 7 is integrally fixed to the head 1, the rotation of the head 1 is maintained in a state in which the engagement convex portion 71 is engaged with the engagement step portion 23a. Is done. In this state, when an operation force of a certain level or more is applied toward the handle portion 22 of the head holder 2 with respect to the distal end portion of the operation lever 7, the engagement between the engagement step portion 23 a and the engagement convex portion 71 is engaged. It is configured to be released.

  Next, the effect | action of the cleaning tool A for windows mentioned above is demonstrated with reference to FIGS.

  When using this window cleaning tool A, as shown in FIG. 5 (a), the handle 6 connected to the head holder 2 is gripped so that the longitudinal direction of the wiper blade 3 is substantially horizontal. While the blade 3 is pressed against the glass surface S of the window glass, the head 1 is slid downward to operate to scrape off water droplets adhering to the glass surface S. At this time, in the window cleaning tool A, the head 1 is rotatable with respect to the head holder 2 around a pair of shaft portions 21 parallel to the longitudinal direction of the head 1, and the head 1 has a pair of guide bodies. 5 is provided, the pair of guide bodies 5 (guide portions 51) abut against the glass surface S together with the wiper blade 3 by pressing the wiper blade 3 against the glass surface. Here, since the pair of guide bodies 5 are provided at a predetermined interval in the longitudinal direction of the head 1, the wiper blade 3 can contact the glass surface S over the entire length in the longitudinal direction. When the head 1 is slid down as it is, as shown in FIG. 5B, the head 1 is rotated with respect to the glass surface S by rotating around the pair of shaft portions 21 with respect to the head holder 2. A predetermined posture is maintained. That is, even if the angle α between the glass surface S and the handle 6 changes due to the change in the height of the head 1, the wiper blade 3 is maintained at a predetermined angle with respect to the glass surface S. Water droplets adhering to the surface S can be removed. Therefore, according to the present invention, when removing water droplets adhering to the window glass, it is possible to work on the window glass in a range from a high place to a low place without any inconvenience, and work efficiency is improved.

  In the window cleaning tool A in the present embodiment, when the guide portion 51 is in contact with the glass surface S together with the wiper blade 3, the contact portion 51a of the guide portion 51 with the glass surface S is the wiper blade 3. On the other hand, since it is configured to be positioned on the head holder 2 side, the contact portion 51a is positioned below the wiper blade 3 when removing water droplets on the window glass. Therefore, if the pair of guide portions 51 are brought into contact with the glass surface S together with the wiper blade 3, the wiper can be used even if the angle between the glass surface S and the handle 6 changes due to the change in the height of the head 1. The state in which the blade 3 is inclined slightly or vertically downward with respect to the glass surface S is appropriately maintained. Therefore, according to the present invention, since the wiper blade 3 can slide the head 1 downward while maintaining an appropriate angle with respect to the glass surface S, water droplets adhering to the glass surface S are scraped off appropriately. This is suitable for improving work efficiency.

  In the present embodiment, the guide portion 51 has a curved shape in which the contact portion 51a protrudes toward the glass surface S when the guide portion 51 is in contact with the glass surface S together with the wiper blade 3. 3, when the head 1 is slid downward while being pressed against the glass surface S, the contact resistance between the glass surface S and the guide portion 51 can be reduced. In addition, as shown in FIG. 6, the guide portion 51 does not get caught by the protruding portion P and acts like a hook even on the protruding portion P such as a crosspiece protruding from the glass surface in the middle of the window glass in the vertical direction. It is possible to get over smoothly. Therefore, even when removing water droplets from the window glass having such a protrusion P, the work can be performed without any inconvenience, which is preferable in improving work efficiency. Here, since the contact part 51a of the guide part 51 and the contact part 3a with respect to the glass surface S of the wiper blade 3 have a comparatively large predetermined space | interval, the attitude | position with respect to the glass surface S of the head 1 changes almost. Without any effect on the function of removing water droplets. Therefore, it is possible to remove the water droplets adhering just before the protruding portion P without leaving them.

  Further, in the present embodiment, the guide portion 51 is indicated by a dotted line in FIG. 7 with respect to a load for pressing the head 1 against the glass surface S in a state where the guide portion 51 is brought into contact with the glass surface S together with the wiper blade 3. It is elastically deformed. Therefore, when the guide part 51 hits the protrusion part P, an impact is absorbed by the suspension effect, and the protrusion part P can be overcome more smoothly. If the guide portion 51 is elastically deformable as described above, only the wiper blade 3 is elastically deformed with respect to the load for pressing the head 1 against the glass surface S, and the wiper blade 3 is made of glass. Inclination with respect to the surface is suppressed, which is suitable for properly scraping off water droplets adhering to the glass surface.

  In the window cleaning tool A according to the present embodiment, a lock mechanism L that can lock the head 1 with respect to the head holder 2 is provided, so that the lock mechanism L is allowed to act. Thus, the same usage method as in the prior art becomes possible. That is, if the head 1 is locked so as to restrict the rotation, the wiper blade 3 can be pressed against the glass surface S without bringing the guide portion 51 into contact with the glass surface S as shown in FIG. it can. Therefore, it is possible to select a method of use when removing water droplets from the window glass, which improves usability for the operator.

  In the present embodiment, the engagement of the engaging projection 71 of the operating lever 7 and the engaging step 23a of the head holder 2 maintains the locked state in which the rotation of the head 1 is restricted (see FIG. 3), while the structure of the lock mechanism L can be simplified, it is possible to appropriately avoid the problem that the lock state is unfairly released during the work.

  In the window cleaning tool A according to the present embodiment, the sponge body 4 having a predetermined length in the longitudinal direction of the head 1 is mounted at a position separated from the wiper blade 3. It is possible to use such as impregnating with water or detergent and rubbing the glass surface S to wipe off dust adhering to the glass surface S, and then removing water droplets adhering to the glass surface S with the wiper blade 3. Thus, since the window cleaning tool A according to the present invention has two different types of cleaning functions, it is not necessary to prepare two types of window cleaning tools separately, and in order to improve the cleaning work efficiency. Is preferred. Further, if the lock mechanism L is operated when the sponge body 4 is used, the head 1 does not rotate even when the sponge body 4 is pressed against the glass surface S, and the work can be performed stably.

  FIGS. 10-13 has shown the other example of the cleaning tool for windows which concerns on this invention. In FIG. 10 and subsequent drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and the description thereof is omitted.

  According to the present embodiment, when the head 1 is slid downward, as shown in FIG. 10B, the operator can use the head 1 to slide downward with the handle 6 facing diagonally upward. As a result, it is convenient for the operator. Specifically, the work can be performed while shifting only the head 1 in the horizontal direction without moving in the horizontal direction with respect to the glass surface S to be worked. Further, even when the worker cannot be positioned directly under the cleaning portion of the glass surface S, the head 1 can be slid downward at the cleaning portion and adheres to the periphery of the corner portion of the glass surface S. Water drops can be removed without leaving. In addition, the flexible part in this invention is not limited to what is comprised by elastic members, such as rubber | gum mentioned above. For example, you may comprise by the joint member which can rotate to all directions, such as a universal joint. Furthermore, the flexible portion is not limited to the one constituted by the separate member as described above. For example, the flexible part can be configured by integrally forming the head and the head holder with resin, and providing a portion between them that can be bent and deformed by an external force of a predetermined value or more.

  In the window cleaning tool A2 shown in FIG. 11, the structure of the guide body is different from that in the above embodiment. In the present embodiment, each of the pair of guide bodies 5 ′ has a roller 53 instead of the guide portion 51 in the above embodiment. More specifically, the roller 53 is attached to a support portion 54 provided so as to extend from the head 1 and is configured to be rotatable around a central axis H parallel to the longitudinal direction of the head 1.

  According to this embodiment, when the head 1 is slid downward while the roller 53 is pressed against the glass surface S together with the wiper blade 3, the roller 53 rolls on the glass surface S as shown in FIG. This means that the contact resistance of the guide body 5 ′ with respect to the glass surface S can be reduced more efficiently. Even when there is a protrusion P protruding from the glass surface S, if the outer diameter of the roller 53 is set to a predetermined size or more corresponding to the height of the protrusion P, the roller 53 is not caught by the protrusion P. It is possible to get over smoothly. In addition, if the outer peripheral part of the roller 53 is formed of a material excellent in gripping force with respect to the glass surface such as rubber, the roller 53 is prevented from slipping on the glass surface S, and the roller 53 is placed on the glass surface S. Suitable for smooth rolling.

  A window cleaning tool A3 shown in FIG. 13 shows a modification of the window cleaning tool A2. In the window cleaning tool A2 shown in FIG. 11, the guide body 5 ′ has a configuration in which one roller 53 is attached to the support portion 54. However, in this window cleaning tool A3, the guide body 5 ″ is The plurality of rollers 53 ′ are mounted on the support portion 54 ′, more specifically, the support portion 54 ′ has a glass surface when the wiper blade 3 is in contact with the glass surface S.
