Description

The present invention relates to a flooring wiper for cleaning wooden floors.

Flooring wipers for cleaning wooden floors are known, as disclosed in US Pat. This flooring wiper generally has a handle, a rectangular wiper head attached to the tip of the handle, and a wiping cloth attached to the wiper head so as to cover the entire lower surface of the wiper head, The floor surface is cleaned by pressing the wiping cloth against the floor surface with the wiper head. The wiping cloth is usually impregnated with a cleaning solution, wax, or the like.
When the floor wiper is used to clean a corner of a room, the end of the wiper head may contact the wall to generate noise or damage the wall. Therefore, like the second and third flooring wipers disclosed in Patent Literature 2 or Patent Literature 3, there is also known a wiper head provided with an elastic cushioning portion at the side end portion thereof. .

Among them, the second flooring wiper disclosed in Patent Document 2 is provided with flexible elastic pieces that are bent in a V shape as the cushioning portions at the front and rear and/or the left and right side ends of the wiper head. The elastic piece provides cushioning properties.
However, in the second flooring wiper, when the wiper head comes into contact with the wall, the elastic piece is interposed between the wiper head and the wall surface. A gap is formed between the wiper head and the wall surface, and there is a problem that the gap cannot be cleaned.

On the other hand, in the case of the third flooring wiper disclosed in Patent Document 3, in order to provide cushioning properties, the four sides of the wiper head are provided with an upward wall that rises vertically upward and an upper end of the upward wall. and a downward wall that is vertically folded back from the bottom to form a buffer wall.
However, in this third flooring wiper, since the four buffer walls formed on the four sides of the wiper head are all connected together, it is difficult to elastically deform, and the downward wall is not the upward wall. Since it extends directly downward with a small gap between them, the range of movement is narrow, and for this reason, there is a problem with cushioning.

The body portion 11 has a plate-like shape having an upper surface 11a to which the handle 2 is attached and a lower surface 11b to which the wiper cloth 20 is attached and pressed against the floor surface 30. Its thickness is about 2.5 mm. It is formed to be about 5 mm.

As shown in FIGS. 4 and 6, the lower surface 11b of the body portion 11 has a plurality of recesses 17 for attaching the first hook-and-loop fasteners 16 for fixing the wipe cloth 20. As shown in FIGS. Each of these concave portions 17 has a rectangular contour shape of the same shape and size, and two concave portions 17 are formed on both left and right sides of the main body portion 11 bordering on the central position in the left-right direction. The first hook-and-loop fastener 16 has hook-shaped projections that are entwined with the fibers of the wiping cloth 20, and a member formed separately from the wiper head 10 is adhered to substantially the entire inner bottom surface of the recess 17. It is provided on the wiper head 10 by attaching it with a bonding means such as adhesive or double-sided adhesive tape, or by integrally forming the hook-shaped protrusion with the wiper head 10 . The depth of the concave portion 17 is such that the hook-shaped protrusion of the first hook-and-loop fastener 16 protrudes from the lower surface 11a of the main body portion 11 by an amount that can be engaged with the wiping cloth 20 .

As shown in FIGS. 2 to 5, a handle attachment portion 5 for attaching the handle 2 is formed on the upper surface 11a of the body portion 11 so as to be positioned at the center of the upper surface 11a in the front-rear direction and the left-right direction. It is The handle attachment portion 5 has a convex shape protruding upward, and the upper end portion thereof is formed as a pair of tubular bearing portions 5a, 5a to which the universal joint 4 is connected.

Protrusions 15 protruding upward from the upper surface 11 a of the body portion 11 are provided on both sides of the handle attachment portion 5 in the left-right direction. The convex portion 15 is formed by forming the concave portion 17 in the lower surface 11b of the main body portion 11, and extends from the handle attachment portion 5 to one end and the other end of the main body portion 11 in the left-right direction. extended. The width of the protrusion 15 occupies about 1/3 of the length of the wiper head 10 in the front-rear direction.

Further, on the upper surface 11a of the main body portion 11, a plate-like rib 14 vertically rising from the upper surface 11a is provided at the center position of the upper surface 11a in the front-rear direction. It is formed to extend to one end and the other end of the direction. The rib 14 rises upward from the flat top surface 15a of the convex portion 15 and linearly extends toward both ends of the body portion 11 in the left-right direction. Further, the height of the rib 14 is highest at the portion connected to the handle attachment portion 5, and gradually decreases from the handle attachment portion 5 side toward one end side and the other end side in the left-right direction of the main body portion 11. . The width of the rib 14 is formed thinner than the width of the handle attachment portion 5 in the front-rear direction, and is constant over the entire length of the rib 14 .

A plurality of second hook-and-loop fasteners 18 are attached to the upper surface 11a of the main body 11 for detachably locking the wiper cloth 20 on the upper surface 11a side. The second hook-and-loop fasteners 18 have the same hook-shaped projections as the first hook-and-loop fasteners 16, and a pair of hook-and-loop fasteners 18 are provided near both ends in the longitudinal direction of the main body 11, facing each other in the front-rear direction. There are 4 in total. Like the first surface fastener 16, the second surface fastener 18 may be integrated with the wiper head 10 or may be separate therefrom.

The end wall portions 12 stand up from the respective edges of the upper surface 11a of the main body portion 11 and extend over the entire length of the edges. All of the end wall portions 12 have the same height dimension, and the adjacent end wall portions 12, 12 are smoothly connected to each other via arc-shaped connecting portions 12a at the four corners of the main body portion 11. As shown in FIG. The thickness of the end wall portion 12 is approximately 2 mm, which is thinner than the thickness of the main body portion 11 . A corner portion where the end wall portion 12 and the main body portion 11 are connected is formed in an arc shape.

The elastic wall portion 13 is formed independently for each end wall portion 12 , and the tip 13 a is elastically deformed in a direction approaching the end wall portion 12 . That is, when the elastic wall portion 13 comes into contact with the wall 31 , the elastic wall portion 13 can be elastically deformed toward the end wall portion 12 with the connecting portion 19 connecting the elastic wall portion 13 and the end wall portion 12 as a fulcrum. It has a cushioning function due to elastic deformation. Since the elastic wall portions 13 are provided on the four sides of the wiper head 10 , even if any edge of the wiper head 10 contacts the wall 31 , the impact is mitigated. In addition, since the adjacent front and rear elastic wall portions 13 and left and right elastic wall portions 13 are separated from each other, each elastic wall portion 13 can be independently and reliably elastically deformed. The thickness of the elastic wall portion 13 is smaller than the thickness of the end wall portion 12, preferably about 1/3 to 1/2 of the thickness of the end wall portion 12. In this embodiment, the thickness is about 1 mm. It is formed in a thin plate shape. Therefore, it is easy to elastically deform and excels in cushioning properties.

In addition, the tip 13a of the elastic wall portion 13 is positioned on the same plane as the lower surface 11b of the main body portion 11 in a state in which it is not elastically deformed. The wiping cloth 20 can be pressed against the floor surface 30 by the tip 13a even when the wiping cloth 20 is pressed. In this manner, the elastic wall portion 13 has the cushioning function, and also has the cleaning function of cleaning the floor surface by constantly pressing the wiper cloth 20 with the tip 13a. The tip 13a of the elastic wall portion 13 is formed in an arc shape so that the wiping cloth 20 can always be stably pressed against the floor surface 30 regardless of the angle of the elastic wall portion 13. It is

When cleaning the floor surface 30 with the flooring wiper 1A, first, the wiping cloth 20 is wound so as to cover the entire lower surface 11b of the main body 11 and both ends of the upper surface 11 of the main body 11 in the front-rear direction. , first and second hook-and-loop fasteners 16 and 18 to the wiper head 10 . In this state, the elastic wall portions 13 positioned at the front and rear edges are covered with the wiping cloth 20 . The floor surface 30 is cleaned by pressing the lower surface 11b of the body portion 11 against the floor surface 30 and pushing the wiper head 10 back and forth or left and right. As shown in FIG. 7, when the wiper head 10 is not in contact with the wall 31 and the elastic wall portion 13 is not elastically deformed, the wiping cloth 20 and the lower surface 11b of the main body portion 11 are on the same plane. It is pressed against the floor surface 30 while being compressed with the tip 13a.

As shown in FIG. 8, when the front or rear edge of the wiper head 10 contacts the wall 31, the elastic wall portion 13 is elastically deformed toward the end wall portion 12. The impact is softened. At this time, even if the elastic wall portion 13 is elastically deformed toward the end wall portion 12, the wipe cloth 20 is kept pressed against the floor surface 30 by the tip 13a thereof. Even if there is, it can be cleaned without fail. In particular, even during the elastic deformation, the arcuate tip 13a always presses the wiping cloth 20 stably against the floor surface 30, so that the elastic wall portion 13 maintains a good cleaning condition. be. Further, even if the elastic wall portion 13 elastically deforms and the tip 13a protrudes slightly downward from the lower surface 11b of the main body portion 11, the protruding portion is compensated by the wiping cloth 20 being compressed. Since it is absorbed, it does not interfere with cleaning.
Thus, according to the flooring wiper 1A, the wiper head 10 is excellent in cushioning properties when it comes into contact with the wall 31, and even on the floor surface 30 near the wall 31, which is difficult to clean, every corner can be wiped clean. can be cleaned to

In the above-described embodiment, the tip 13a of the elastic wall portion 13 is configured to be positioned on the same plane as the lower surface 11b when the elastic wall portion 13 is not elastically deformed. As shown, the front end 13a is pushed downward from the lower surface 11b of the main body 11 within a range (for example, 1 mm or less) in which the wiper cloth 20 can be pressed against the floor surface 30 regardless of whether or not the elastic wall portion 13 is elastically deformed. can also be formed to be positioned slightly above. In this case, there is a slight difference in the force with which the wipe cloth 20 is pressed against the floor surface 30 between the lower surface 11b of the main body portion 11 and the tip 13a of the elastic wall portion 13. If the wipe cloth 20 is used, cleaning will not be hindered.
Further, the end wall portion 12 and the elastic wall portion 13 connected to the end wall portion 12 may be provided at least on the front and rear edges of the front, rear, left and right edges of the wiper head 10. It is not necessary to provide all the front, rear, right and left edges of the wiper head 10 as in the embodiment.
