DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool used for cleaning a floor or the like.

[0002]

2. Description of the Related Art Conventionally, for cleaning a floor surface, etc., dust is collected on the lower surface of the cleaning head by wiping the floor surface with the lower surface of a cleaning head rotatably connected to the tip of a handle. A cleaning tool of a type that causes the cleaning is widely used. However, when the floor surface or the like is wiped with a conventional cleaning tool, the front edge of the lower surface of the cleaning head that is orthogonal to the cleaning direction (the moving direction of the cleaning head) tends to be pressed most strongly against the floor surface or the like. . For this reason, the area where dust is collected is mainly limited to the outer peripheral edge of the cleaning head, and there is a problem that the entire lower surface of the cleaning head cannot be effectively used.

In order to solve such a problem, a cleaning tool described in, for example, JP-A-11-244210 has recently been proposed. The cleaning tool described in this publication is configured such that the lower surface of the cleaning head is a curved surface that projects downward at the center and gradually curves upward toward both edges along the cleaning direction. When the floor is wiped off with the cleaning tool, if a strong force is applied, the front curved surface of the lower surface of the cleaning head, which is orthogonal to the cleaning direction, is strongly pressed against the floor or the like. Moves from the curved surface toward the center. Therefore, dust can be collected on the entire lower surface of the cleaning head, and the collection area can be made wider than that of the conventional cleaning tool, so that the efficiency of collecting dust can be improved.

[0004]

However, in the cleaning tool described in the above-mentioned publication, the cleaning operation is performed because the lower surface of the cleaning head is integrally formed so as to be convex in advance. If there is irregular unevenness on the floor, etc.,
There was a problem that it was not possible to cope well and there was left wiping. In addition, especially when the floor surface is wiped with the curved surface portion of the cleaning head, the lower surface of the cleaning head comes into line contact with the floor surface or the like. There was also a problem that it could not be wiped.

The present invention has been made by focusing on the problems existing in the prior art as described above. The purpose is to effectively utilize the wide area on the lower surface of the cleaning head as a dust collecting area, and to cope with irregular irregularities on the floor surface etc. An object of the present invention is to provide a cleaning tool that can be cleaned and that can be wiped by bringing the lower surface of the cleaning head into surface contact with a floor surface or the like.

[0006]

In order to achieve the above object, the present invention is directed to a cleaning method for wiping a floor or the like with a lower surface of a cleaning head rotatably connected to one end of a handle. In the tool, the cleaning head may include a head body, an interposed member made of an elastic material attached to a lower surface of the head body, and a cleaning material for collecting dust attached to the lower surface of the interposed member. The gist consists of:

According to a second aspect of the present invention, in the cleaning tool of the first aspect, a gap is provided between at least an edge of a lower surface of the head body and an upper surface of the interposition member. And

According to a third aspect of the present invention, in the cleaning tool according to the first or second aspect, the lower surface of the head body is inclined or curved from both edges along the cleaning direction toward the center. The gist is that

According to a fourth aspect of the present invention, in the cleaning tool according to any one of the first to third aspects, the intervening member is configured to be detachable from the head body. I do.

The portion from both edges to the center along the left and right direction in FIG. 4) is a downwardly inclined surface S, and only the center is a flat surface F. The flat surface F is provided with a pair of recesses 18 (see FIG. 3) for mounting the interposition member 15 on the center line in the width in the short direction.

As shown in FIG. 1, holding means 19 for detachably holding the wiping cloth 16 are provided near four corners on the upper surface of the head main body 14, respectively. The holding means 19 is composed of a plurality of radially extending slits (radial slits 19a). Further, a pair of fan-shaped locking portions 20 are provided near the universal joint 17 on the upper surface of the head main body 14 so as to sandwich a center line in the longitudinal width of the head main body 14 therebetween. The locking portion 20 is the head body 14
Are formed in a gently raised shape with the central portion of the as an apex. A handle fixing groove 21 having a concave shape is provided in the middle of the locking portions 20. The handle fixing groove 21 can be fitted to the handle 12 tilted so as to be substantially parallel to the upper surface of the head body 14, so that the rotation of the cleaning head 13 in the left-right direction is restricted. Has become.

Next, the interposed member 15 is made of an elastic material such as EVA (ethylene vinyl acetate copolymer resin) or polyethylene, and is slightly larger than the head main body 14 and has a substantially rectangular planar shape with four corners in an arc shape. Is formed. The upper surface of the interposition member 15 has an annular rising portion 15a erected along the outer edge at a predetermined distance from the outer edge of the interposition member 15. On the upper surface of the interposition member 15, a pair of cylindrical projections 22 that are fitted into the pair of recesses 18 of the head main body 14 protrude on the center line in the width in the short direction. And this recess 18
The interposition member 15 is attached to the lower surface of the head main body 14 by fitting the protrusions 22 with the projections 22. This fitting can be released by applying a force in a direction to separate them, and the head main body 14 and the interposition member 15 can be separated.
As shown in FIGS. 3 and 4, when the interposition member 15 is attached to the head main body 14, the outer periphery of the lower end of the head main body 14 is fitted inside the rising portion 15 a of the interposition member 15.

Next, the wiping cloth 16 is woven from cotton, polyester, rayon or the like. As shown in FIG. 1, the wiping cloth 16 is formed in a substantially rectangular shape with four corners in an arc shape, and an overhang 16a is provided on an outer peripheral edge thereof. As shown in FIG. 2, the wiping cloth 16 is wound so as to cover the lower surface thereof along the short direction of the interposition member 15, and the four corners are pressed into the holding means 19, so that the Mounted on the bottom. As shown in FIG. 4, the interposition member 15 has a downwardly convex shape below the head body 14 while leaving a predetermined gap between the inclined surface S of the head main body 14 and the upper surface of the interposition member 15. The wiping cloth 16 is mounted in a state where the wiping cloth 16 is elastically deformed. As shown in FIG. 1, the wiping cloth 16 has a large number of pile brushes only on the front and back surfaces of a region that contacts the lower surface of the interposition member 15 when the wiping cloth 16 is mounted on the lower surface of the interposition member 15. A pile raising portion P composed of 23 is provided. In FIG. 2, the pile raising 23 is omitted and shown in FIGS.
3 shows only the pile raising 23 located at the position corresponding to the lower surface of the cleaning head 13.

Next, the cleaning tool 1 constructed as described above is used.
1 will be described. When cleaning the floor surface A using the cleaning tool 11 of the present embodiment, the handle 12 is gripped, and the floor surface A is wiped with the lower surface of the cleaning head 13. Then, dust is collected on the lower surface of the cleaning head 13, that is, between the pile raisings 23 of the wiping cloth 16.

At this time, as shown in FIG. 5, when the cleaning head 13 is moved along its short direction (the direction of the arrow in FIG. 5), the cleaning head 13 is moved rearward (to the left in FIG. 5). )
5, a force is applied to the front (rightward in FIG. 5), so that the interposition member 15 is elastically deformed so that the gap between the front inclined surface S and the upper surface of the interposition member 15 is reduced. . Then, the portion from the intermediate portion to the rear of the cleaning head 13 is lifted upward, and the front lower surface of the cleaning head 13 is pressed against the floor surface A and is in surface contact. At this time, since the portion from the intermediate portion to the rear of the cleaning head 13 is lifted upward, the point of action of the force transmitted from the handle 12 to the cleaning head 13 via the universal joint 17 is also lifted upward and moved slightly forward. . As a result, a more nearly uniform force can be transmitted from the handle 12 to the front lower surface of the cleaning head 13 pressed against the floor surface A.
Therefore, the entire front of the lower surface of the cleaning head 13 can be used as a dust collecting area.

The pile raising 2 on the lower surface of the cleaning head 13
3 is in surface contact with the entire lower surface of the cleaning head 13, so that the pile brushing 23 contacts the floor surface A even in a portion from the middle part to the rear of the cleaning head 13 so that dust can be collected. ing.

When the cleaning head 13 is moved in the direction opposite to the arrow in FIG. 5, the portion on the opposite side from the above can be used as a dust collecting area. Therefore, a wide area on the lower surface of the cleaning head 13 can be effectively used as a dust collecting area.

According to the embodiment described above, the following effects can be obtained. (1) Since the interposition member 15 is provided between the head main body 14 and the wiping cloth 16, wiping can be performed satisfactorily even with irregular irregularities on the floor surface A. Therefore, there is no possibility that unwiped residue will be generated, and the trouble of wiping twice can be eliminated.

(2) When wiping the cleaning head 13 by moving the cleaning head 13 along its short direction, the clearance between the front inclined surface S of the cleaning head 13 and the upper surface of the interposition member 15 is reduced. The mounting member 15 is elastically deformed, and the front of the lower surface of the cleaning head 13 is brought into pressure contact with the floor surface A to be in surface contact. For this reason, compared with the conventional cleaning tool in which wiping is performed in the state of line contact, the floor surface A can be simultaneously wiped in a wide area on the lower surface of the cleaning head 13, and the cleaning efficiency can be improved.

(3) Due to a gap provided between the inclined surface S of the head body 14 and the upper surface of the interposition member 15, the interposition member 15 at a position corresponding to a position below the inclined surface S is further deformed. Can be tolerated.

(4) Since the interposition member 15 is elastically deformed along the inclined surface S of the head main body 14, there is no possibility that the interposition member 15 is excessively deformed. (5) Since the interposition member 15 can be removed from the head main body 14, replacement of the interposition member 15 and cleaning of the lower surface of the head main body 14 can be easily performed.

(6) Since the pile raised portions P are provided on both the front and back surfaces of the wiping cloth 16, after using one side, the back side can be used by turning over. Furthermore, it is very economical because it is possible to wash and reuse it even after both sides are used.

(7) Since the wiping cloth 16 is held by the holding means 19 of the head main body 14 and is mounted on the lower surface of the interposition member 15, there is no possibility that the wiping cloth 16 will fall off during cleaning. (8) The interposition member 15 is formed of an elastic material, and is formed slightly larger than the head main body 14. Therefore, the floor A
There is no risk of damaging the surface, and there is no risk of generating noise during wiping.

The above embodiment can be modified as follows. The entire lower surface of the head body 14 may be formed flat. In this case, it is preferable that the thickness of the interposition member 15 is formed to be thicker than in the case of the above embodiment. In the case of such a configuration, substantially the same effect as in the above-described embodiment can be obtained by the elastic deformation of the interposition member 15.

In the embodiment, the wiping cloth 16 is tightly attached to the lower surface of the interposition member 15 so that the interposition member 15 is elastically deformed so as to have a downwardly convex shape below the head body 14. However, the wiping cloth 16 may be loosely mounted so that the lower surface of the interposition member 15 becomes flat.

In the embodiment, the lower surface of the head main body 14 is configured to be inclined from both edges along the short direction toward the center, but in addition, from the both edges along the longitudinal direction to the center. It may be configured to be inclined or curved toward the front. With this configuration, even when the cleaning head 13 is moved in the longitudinal direction to perform wiping, a wide area on the lower surface of the cleaning head 13 is effectively used as a dust collecting area, as in the case of the embodiment. can do. Also,
Similarly, when the cleaning head 13 is moved in the longitudinal direction to perform wiping, the wiping can be appropriately performed in response to irregular irregularities on the floor surface A, and the lower surface of the cleaning head 13 is brought into surface contact with the floor surface A. Therefore, the floor surface A can be wiped at the same time in a wide area.

The method of mounting the wiping cloth 16 on the lower surface of the interposition member 15 may be changed, for example, such that the lower surface of the interposition member 15 and the upper surface of the wiping cloth 16 are fixed with a planar fastener and mounted. .

The head body 14 and the interposition member 15 are attached at at least one position except the edge so as to have a gap between at least the edge of the lower surface of the head body 14 and the upper surface of the interposition member 15. For example, the concave portion 18 and the convex portion 22 of the embodiment may be omitted, and attached with an adhesive.

The cleaning material may be any material that can be attached to the lower surface of the interposition member 15, and may be, for example, a commercially available disposable nonwoven fabric sheet. The lower surface of the head main body 14 may be formed in a downwardly convex curved shape. Further, the inclined surface S of the embodiment may be a curved surface that is convex downward.

The intervening member 15 may have a two-layer structure in which the upper layer is made of EVA and the lower layer is made of polyethylene. next,
The technical idea that can be grasped from the embodiment will be described below.

The outer peripheral edge of the interposition member is located outside the outer peripheral edge of the head main body.
The cleaning tool according to any one of claims 1 to 4. With such a configuration, the outer peripheral edge of the head body does not directly hit the floor surface or the like at the time of wiping, so that there is no possibility of damaging the floor surface or the like.

[0034]

Since the present invention is configured as described above, it has the following effects. According to the first aspect of the present invention, a wide area on the lower surface of the cleaning head can be effectively used as a dust collecting area, and even if there is irregular unevenness on a floor surface or the like, it can be satisfactorily used. Correspondingly, cleaning can be performed without leaving any wiping, and wiping can be performed by bringing the lower surface of the cleaning head into surface contact with a floor surface or the like.

According to the second aspect of the invention, further deformation of the interposition member can be allowed, so that the effect of the first aspect of the invention can be further improved. According to the third aspect of the invention, in addition to the effects of the first or second aspect, the interposition member is elastically deformed along the inclined surface or the curved surface of the lower surface of the head main body. There is no possibility that the mounting member is excessively deformed.

According to the fourth aspect of the present invention, the first aspect is provided.
In addition to the effects of the invention according to any one of the third to third aspects, the interposition member can be replaced.
