Description

  The present invention relates to a cleaning tool that removes dust and dirt on a surface to be cleaned by a cleaning tool body that is used with a cleaning sheet.

  Various cleaning tools are known that remove dust and dirt on a surface to be cleaned such as a floor by a cleaning tool body having a cleaning sheet made of a nonwoven fabric or the like on the cleaning surface. In these cleaning tools, the handle portion attached to the cleaning tool main body is held by hand and the surface to be cleaned is wiped to allow dust and dirt to adhere to the cleaning sheet, thereby enabling easy cleaning.

  Also, with these cleaning tools, if the entire cleaning surface of the cleaning tool body is a flat surface, a large volume of dust or dirt will adhere to the periphery of the cleaning surface covered with the cleaning sheet during wiping. Therefore, it is easy to inhibit the adhesion of small dust and dirt at the central portion of the cleaning surface. In contrast, for example, a cleaning tool has been developed in which the cleaning surface of the cleaning tool body is a convex curved surface that bends at a predetermined curvature so that dust and dirt can be prevented from adhering around the cleaning surface. (For example, refer to Patent Document 1).

Japanese Patent Laid-Open No. 11-244210 JP 2001-299659 A

  On the other hand, according to the cleaning tool of Patent Document 1, since the contact area of the cleaning surface to the surface to be cleaned during wiping is small, it is difficult to efficiently attach dust and dirt to the entire cleaning sheet. For this reason, the cleaning surface of the cleaning tool body is configured to be elastically deformable so as to become a flat surface by a pressing force from the handle portion from a state in which the cleaning portion is curved in a convex shape and its central portion protrudes. Tools have also been developed (see, for example, Patent Document 2).

  According to the cleaning tool of Patent Document 2, dust and dirt are adhered to the entire cleaning sheet while avoiding accumulation of large dust and dirt around the cleaning surface, and efficiently cleaned. Although it is possible to clean the surface, it is easier to switch from a state where a convex curved surface is formed on the cleaning surface to a state where a flat surface is formed on the cleaning surface by the pressing force from the handle. In addition, there is a demand for development of a new technique that can be performed in a stable state and that can clean the surface to be cleaned more efficiently.

  According to the present invention, the switching operation from the state in which the convex curved surface is formed on the cleaning surface to the state in which the flat surface is formed on the cleaning surface by the pressing force from the handle portion is performed more easily and stably. An object of the present invention is to provide a cleaning tool capable of cleaning the surface to be cleaned more efficiently.

  The present invention comprises a cleaning tool body comprising a head body and a cleaning cushion body to be used with a cleaning sheet mounted thereon, and a handle portion attached to a surface opposite to the cleaning surface of the cleaning tool body by the cleaning cushion body. An elastic spacer is provided between the head body and the cleaning cushion body, and the cleaning cushion body is pushed out by the elastic spacer to form a convex curved surface on the cleaning surface. The elastic spacer can be compressed and deformed by a pressing force of the cleaning spacer to form a flat surface on the cleaning surface, and the head main body is interposed between the head main body and the cleaning cushion body. By providing a cleaning tool provided with a sliding guide portion for guiding the cleaning cushion body so as to advance and retreat in a direction perpendicular to the cleaning cushion body, It is those that have achieved.

  According to the cleaning tool of the present invention, the switching operation from the state in which the convex curved surface is formed on the cleaning surface to the state in which the flat surface is formed on the cleaning surface by the pressing force from the handle portion is further facilitated and stable. In addition, the cleaning surface can be cleaned more efficiently.

It is preferable that the sliding guide portion 17 and the restricting means 18 formed of the sliding guide wall portion 19 and the sliding projection portion 20 are provided at one symmetrical position on both sides of the inner side 26. By providing the sliding guide portion 17 and the restricting means 18 at such positions, a flat surface is formed on the cleaning surface 14 by the pressing force from the handle portion 15 from the state in which the convex curved surface 14a is formed on the cleaning surface 14. It is possible to perform the operation of switching to the state of forming a smoother and more stable state.

  Further, in the present embodiment, a locking head 20a having a semicircular cross section is provided at the upper end of the rib-plate-like sliding projection 20. By making the jaw portion of the locking head 20a engageable with the locking overhanging portion 19a of the sliding guide wall portion 19 projecting downward from the inside of the head body 12, the locking head 20a is engaged with the locking head 20a. The restricting means 18 is configured by the extended portion 19a. Thus, when the cleaning cushion body 13 is pushed out by the coil spring 16 as an elastic spacer to form the convex curved surface 14a on the cleaning surface 14, the head body 12 is in the most retracted state with respect to the cleaning cushion body 13. However, the advancement and retraction of the head body 12 can be regulated so that the coil spring 16 retains an elastic biasing force that presses the cleaning cushion body 13 without fully extending the coil spring 16.

  That is, for example, the extension amount from the state in which the coil spring 16 is most compressed until the compression is released and fully extended (to a state in which no elastic biasing force is generated) is F, and the locking head 20a of the sliding projection 20 is slid. When the sliding length slidable inside the motion guide wall portion 19 is the limiter length L, it is possible to set the elastic force by setting (extension amount F until the coil spring 16 is fully extended)> (limiter length L). It is possible to make the head main body 12 in the most retracted state with respect to the cleaning cushion body 13 while maintaining the elastic biasing force by the spacer 16. In the present embodiment, the limiter length L is the distance from the locking overhanging portion 19a to the belt-like support plate 30 in the direction X perpendicular to the cleaning cushion body 13, as shown in FIG. . FIG. 4B is a sectional view of the periphery of the sliding guide portion 17 and the regulating means 18 when the cleaning surface is a flat surface, and the locking overhang portion 19 a is in contact with the belt-like support plate 30.

  Further, in the present embodiment, the spring positioning lower convex portion 31 is provided in each frame of the reinforcing frame portion 30b adjacent to the center side in the longitudinal direction of the portion where the sliding projection portion 20 is provided in the belt-like support plate 30. Is provided so as to protrude upward from the upper surface of the strip-shaped thin plate portion 30a. When the lower end portion of the coil spring 16 is positioned and locked to the lower convex portion 31 for positioning the spring, and the head main body 12 and the cleaning cushion body 13 are joined and integrated, the ceiling of the head main body 12 is fixed. The coil spring 16 is positioned and mounted between the spring positioning upper projection 25 provided on the surface.

  The coil spring provided as the elastic spacer 16 between the head main body 12 and the cleaning cushion body 13 is a known spring member using torsional elasticity formed by, for example, spirally winding a metal linear member, In this embodiment, it is formed in a substantially truncated cone shape in which the diameter of the spiral is reduced from the top to the bottom. Further, as described above, the coil spring 16 maintains the slight compression state even when the head body 12 is most retracted with respect to the cleaning cushion body 13 and the convex curved surface 14a is formed on the cleaning surface 14. 12 and the cleaning cushion body 13.

  According to the cleaning tool 10 of the present embodiment having the above-described configuration, for example, with respect to large dust or dust on the floor surface 22, the cleaning surface 14 is curved to form a convex curved surface 14a. By wiping the floor surface 22, these dust and dirt are adhered to the cleaning sheet 21 of the cleaning surface 14 without being accumulated around the cleaning surface 14. On the other hand, for small dust and dirt on the floor surface 22, a pressing force of, for example, about 2 to 50 N is applied from the handle portion 15 to wipe the floor surface 22 while making the cleaning surface 14 a flat surface and contacting the entire surface. As a result, dust and dirt are efficiently attached to the entire cleaning sheet 21. That is, while the cleaning surface 14 is switched to the convex curved surface 14a or a flat surface by the operation of the handle portion 15, while avoiding the attachment of a large volume of dust or dust around the cleaning surface 14, The floor 22 can be efficiently cleaned by attaching dust and dirt to the entire cleaning sheet 21 covering the cleaning surface 14.

  Then, according to the cleaning tool 10 of the present embodiment, switching from the state in which the convex curved surface 14a is formed on the cleaning surface 14 to the state in which a flat surface is formed on the cleaning surface 14 by the pressing force from the handle portion 15 is performed. The operation can be performed more easily and stably, and the floor surface 22 can be more efficiently cleaned.

  That is, according to the present embodiment, the sliding guide portion that is interposed between the head main body 12 and the cleaning cushion body 13 and guides the head main body 12 to advance and retract in the direction X perpendicular to the cleaning cushion body 13. 17 is provided, for example, even when a pressing force is applied in a direction inclined from the direction X perpendicular to the cleaning tool main body 11 via the handle portion 15, the head main body 12 is cleaned by the sliding guide portion 17. By guiding the cushion body 13 to advance and retract in the direction X perpendicular to the cushion body 13, it is possible to effectively avoid deformation in the shearing direction of the coil spring as the elastic spacer 16, and the cleaning surface 14 is formed into a convex curved surface. It is possible to smoothly perform the operation from 14a to a flat surface, and thereby it is possible to more efficiently clean the floor surface 22 while switching the shape of the cleaning surface 14. It becomes ability.

  Further, according to the present embodiment, the restricting means 18 for restricting the advancement / retraction of the head main body 12 is provided, and the elastic spacer 16 is provided with the elastic biasing force even when the head main body 12 is most retracted with respect to the cleaning cushion body 13. Therefore, it is possible to easily form the convex curved surface 14a on the cleaning surface 14 as a curved surface having an appropriate curvature. In addition, since the elastic spacer 16 is not in a free state, the cleaning surface 14 cannot be switched to a flat surface unless a considerable pressing force is applied. 14a is not crushed. This facilitates the cleaning operation in a state where the cleaning surface 14 is the convex curved surface 14a, and allows large dust, dust, etc. to be effectively attached to the entire cleaning sheet 21.

  Furthermore, according to the present embodiment, the curved shape of the convex curved surface 14a can be set as appropriate by restricting the advance and retreat by the restricting means 18, and the elastic force by the elastic spacer 16 can be set as appropriate. Can be set independently, and the optimum design of the cleaning tool 10 can be easily performed.

  Note that the present invention is not limited to the above embodiment, and various modifications can be made. For example, the elastic spacer provided between the head main body and the cleaning cushion body does not necessarily need to be a coil spring, and may be a leaf spring, rubber, sponge, or the like. In addition, the sliding guide portion that guides the advancement and retraction of the head body and the restricting means that restricts the advancement and retraction of the head body do not necessarily need to be composed of a sliding guide wall portion and a sliding projection portion. A form can be adopted. For example, a pantograph mechanism can be employed. Furthermore, it is not always necessary that the sliding guide part also has a function as a restricting means. Furthermore, the sliding guide portion and the regulating means are not necessarily provided at two positions on both sides of the cleaning tool body, and the number and the mounting position thereof can be set as appropriate. Moreover, the sliding guide part does not necessarily need to be disposed adjacent to the elastic spacer.
