Description

The present invention relates to a draining tool for draining water by scraping water droplets adhering to a window glass, a mirror in a bathroom, or a wall surface with a blade, for example.

Draining tools used to wipe off water droplets and the like adhering to the surface to be cleaned such as window glass have been conventionally known. For example, Patent Document 1 discloses a draining tool including a handle portion H (grip portion), a blade support portion J, a connecting portion C, and a blade portion B (blade). The blade support portion J extends in a direction perpendicular to the direction in which the handle portion H extends. The base end portion of the blade portion B is supported by the tip of the blade support portion J and extends away from the handle portion. The blade portion B also extends along a direction that is perpendicular to the direction in which the blade support portion J extends and intersects the direction in which the handle portion H extends. The connecting portion C is connected to the tip of the handle portion H and the base end of the blade support portion J.

In the draining tool disclosed in Patent Document 1, the connecting portion C extends from the handle portion H in a bifurcated manner and is connected to the blade supporting portion J. According to the draining tool having such a configuration, the rigidity of the connecting portion C is increased, and the connecting portion C is not easily deformed during the draining operation.

For example, when a drainer is used to clean a window glass, the area for wiping water is relatively large. Therefore, during the draining operation, the draining tool repeats the reciprocating operation on the surface of the window glass. However, according to the draining tool described in Patent Document 1, since the connecting portion C has high rigidity, the reciprocating operation on the window glass surface (cleaning target surface) cannot be smoothly performed by a flexible movement. Therefore, the above-mentioned conventional draining tool has room for improvement in terms of workability.

The base end portion of the blade 4 is supported by the tip end portion of the blade support portion 2, and extends to the tip end portion so as to move away from the grip portion 1. As shown in FIGS. 2 and 3, the blade 4 is substantially perpendicular to the direction y (second direction) and intersects the direction x (first direction) in the direction z (third direction). ) Extends along. The angle α formed by the direction x in which the grip portion 1 extends and the direction z in which the blade 4 extends is, for example, in the range of 10 to 25 °, preferably in the range of 10 to 20 °. In the attached drawings, the aspect in which the angle α is 15 ° is shown. In the present embodiment, the thickness of the blade 4 gradually decreases from the base end portion to the tip end portion.

As shown in FIGS. 1, 3 and 4, in the present embodiment, the blade 4 has a blade front surface 4a. The front surface 4a of the blade and the front surface 2a of the support portion in the blade support portion 2 face the side opposite to the side in which the blade 4 is biased with respect to the grip portion 1 in the direction y view (second direction view). In the present embodiment, the blade front surface 4a and the support portion front surface 2a are flush with each other.

Further, the blade 4 is provided with a recess 41 and an engaging piece 42. The recess 41 faces the blade support portion 2 side, and the protrusion 21 of the blade support portion 2 is fitted in the recess 41.

The holding portion 43 is configured to include a slit-shaped through hole, and the thickness of the periphery of the through hole is relatively small. As a result, the portion around the through hole is more easily elastically deformed than the other portions.

The blade 4 is integrally formed by injection molding, for example, with a flexible soft resin material. Examples of such a soft resin material include EVA resin, rubber containing synthetic rubber such as silicone rubber and urethane rubber, soft polyvinyl chloride, and thermoplastic elastomer (TPE).

Next, the operation of this embodiment will be described with reference to FIGS. 6 to 9.

In the present embodiment, the connecting portion 3 connecting the grip portion 1 and the blade supporting portion 2 includes an elastically deformable portion 31. The elastically deformable portion 31 is a portion in which elastic deformation is easily performed in the direction y, which is the direction in which the blade support portion 2 is extended by an external force. According to the drainer A1 having such a configuration, as shown in FIG. 6, the blade support portion 2 and the blade 4 supported by the blade support portion 2 are in the left-right direction (direction substantially along the direction y) in the drawing with respect to the grip portion 1. The elastically deformable portion 31 can be bent so as to rotate in the direction of. In FIG. 6, the state in which the elastically deformable portion 31 is bent by an external force is represented by a virtual line.

For example, when cleaning the surface to be cleaned such as a window glass using the draining tool A1, the range for scraping water is relatively large. Therefore, for example, as shown in FIG. 7, during the draining operation, the draining tool A1 repeats a reciprocating operation accompanied by a U-turn on the surface of the window glass G (cleaning target surface S). As shown in FIG. 8, during the draining operation, the blade 4 is pressed against the surface S to be cleaned and the tip of the blade 4 bends so as to be curved. According to the present embodiment, since the connecting portion 3 includes the elastically deformable portion 31, the draining operation is performed by gripping the blade supporting portion 2 and the blade 4 supported by the blade supporting portion 2 as shown in FIG. It can be performed while rotating left and right with respect to 1. As a result, during the rotation operation of making the drainer A1 U-turn, the force of pressing the cleaning target surface S by the tip of the blade 4 acts substantially evenly over the entire longitudinal direction of the blade 4. Therefore, the reciprocating operation on the window glass surface (cleaning target surface) using the draining tool A1 can be smoothly performed by flexible movement, and water droplets and the like adhering to the cleaning target surface S can be scraped off substantially uniformly. ..

The elastically deformable portion 31 is elongated from the portion connected to the grip portion 1 to the portion connected to the blade support portion 2. Further, as shown in FIG. 5, the cross section 310 perpendicular to the longitudinal center line of the elastically deformable portion 31 has a length in the direction perpendicular to the first dimension L1, which is the length in the direction y. A certain second dimension L2 is large. According to such a configuration, the elastically deformable portion 31 tends to bend in the direction y (horizontal direction in FIG. 5), while the direction y perpendicular to the direction y in the cross section 310 shown in FIG. It is hard to bend in the longitudinal direction of the surface 310). According to such a configuration, as can be understood from FIGS. 1, 3 and 8, when the user presses the blade 4 against the cleaning target surface S side while grasping the grip portion 1, the pressing force is elastic. It is avoided that the easily deformable portion 31 is deformed. As a result, the blade 4 can be appropriately pressed against the surface S to be cleaned.

In the present embodiment, the cross section 310 has a long rectangular shape having a first side 311 and a second side 312. The first side 311 is substantially along the direction y. The second side 312 is substantially perpendicular to the first side 311 and is longer than the first side 311. According to such a configuration, the characteristic regarding the direction in which the external force acts on the elastically deformable portion 31 described above with reference to FIG. 5 (while the elastically deformable portion 31 tends to bend in the direction y, the cross section shown in FIG. 5). A point on the surface 310 that does not easily bend in the direction perpendicular to the direction y) can be realized by a simple structure. The cross section of the elastically deformable portion 31 is not limited to a rectangular shape as described above, but various shapes such as an elliptical shape or a hollow shape can be adopted.

The elastically deformable portion 31 has a rib 32 protruding in the direction y from the side surface to which the first side belongs. According to such a configuration, it is possible to effectively suppress the twisting deformation around the longitudinal center line of the elastically deformable portion 31 during the work using the draining tool A1.

The blade support portion 2 and the blade 4 each have a support portion front surface 2a and a blade front surface 4a facing the side opposite to the side on which the blade 4 is biased with respect to the grip portion 1 in the direction y. The front surface 2a of the support portion and the front surface 4a of the blade are flush with each other, and the blade support portion 2 and the blade 4 are provided with holding portions 22 and 43. According to such a configuration, as shown in FIG. 9, the wiping material W can be held by the holding portion 22 (43) so as to cover the support portion front surface 2a and the blade front surface 4a. The wiping material W is made of, for example, a cloth material having a predetermined thickness. Then, by rubbing the front surface 2a of the support portion and the front surface 4a of the blade against the surface S to be cleaned, the surface S to be cleaned after the draining operation shown in FIGS. 7 and 8 can be wiped off. Therefore, according to the present embodiment, it is possible to efficiently perform a series of operations of draining and wiping finish after washing the surface S to be cleaned with water.

The holding portions 22 and 43 for holding the wiping material W are provided at two or more positions separated from each other in the direction y. According to such a configuration, the wiping material W can be appropriately held. In the present embodiment, as is well shown in FIG. 1, the holding portions 22 and 43 are provided at three positions separated from each other in the direction y, and the wiping material is provided even if the dimension of the blade 4 in the direction y is relatively large. It is possible to hold W properly.

In the present embodiment, the angle α formed by the direction x in which the grip portion 1 extends and the direction z in which the blade 4 extends is in the range of 10 to 25 °. According to such a configuration, as will be understood with reference to FIGS. 8 and 9, in both the draining work and the wiping finishing work, the grip portion 1 is in a posture of being appropriately inclined with respect to the surface S to be cleaned. Work can be performed and workability is excellent.
