Has the function of

On the inner surfaces on both sides corresponding to the inclined sides of the end surface of the square cylinder portion 36a, there are two lower ridge portions 36e extending inward from the end surface in the cylinder axis direction. The two lower convex portions 36e are determined so that the intersection angle with the upper surface portion of the mop head 10 is in the range of 40 degrees to 70 degrees when the tubular lock member 36 is covered with the two-dimensional rotary joint 32. It is designed to be detachably fitted to the lower concave portion 31c recessed in the outer surface of each bracket rib 31a so as to have an angle. The uneven relationship between the lower convex portion 36e and the lower concave portion 31c may be reversed. That is, the lower convex portion 36e may be provided as the lower concave portion, and the lower concave portion 31c may be provided as the lower convex portion.

The cylindrical portion 36b has two upper convex portions 36d on both sides of the inner surface. The circumferential positions of the two upper ridges 36d correspond to the two lower ridges 36e provided on the inner surface of the square cylinder 36a, and extend inward from the end face in the cylinder axis direction. The two upper ridges 36d are located in the slit 34c when the tubular lock member 36 is in the second position, and the upper ridges 36d when the tubular lock member 36 is pulled up to the first position. It is designed to fit into the portion 34g. The uneven relationship between the upper convex portion 36d and the upper concave portion 34g may be reversed. That is, the upper convex portion 36d may be provided in the upper concave portion, and the upper concave portion 34 g may be provided in the upper concave portion.

The cylindrical portion 36b has a locking projection 36g projecting from the inner surface portion of the upper end of the cantilever arm portion 36f formed between the slits by two slits downward from the upper end. The locking projection 36g is provided in the vicinity of the lower side of the ascending stop projection 34f of the second rotating body 34 when the tubular lock member 36 is pulled up to the first position and comes into contact with the ascending stop projection 34f. It is designed to fit into the stop recess 34h. As a result, the cylindrical lock member 36 is stopped at the first position.

As shown in FIGS. 2 and 3, the cylindrical lock member 36 is provided so as to move between a first position located in the pulled-up state and a second position located in the pulled-down state. ..

When the tubular lock member 36 is in the first position, the restraint of rotation of the two-dimensional rotary joint 32 by the tubular lock member 36 is released. In this state, the disposable paper P is wrapped around the mop head 10 and the dirt on the flooring is wiped off.

Further, when the tubular lock member 36 is in the second position, the square tubular portion 36a of the tubular lock member 36 covers the two-dimensional rotary joint 32, and the end surface 36c of the rectangular tubular portion 36a hits the pedestal portion 11c. At the same time as being in contact with the bracket 31, the cylindrical portion 36b is externally fitted to the operation rod 20. As a result, the tilt angle θ (see FIG. 3) of the operation rod 20 with respect to the mop head 10 coincides with the tilt angle of the lower end surface of the tubular lock member 36.

The tilt angle θ may be determined to be an appropriate angle within the range of, for example, 40 degrees to 70 degrees, but mechanically and so as to maximize the force of grasping the operation rod 20 and pressing the mop head 10 against the carpet. The angle is preferably determined from an ergonomic point of view.

Next, the actions and effects of the dual-purpose mop 1 and the connecting structure 30 according to the present embodiment will be described with reference to FIGS. 1 to 13.

In the connecting structure 30 according to the present embodiment, since the tubular lock member 36 cannot rotate in the circumferential direction of the operation rod 20, the tubular lock member 36 is located at the first position and the second position on a straight line. It can move smoothly between them, and it is easy to switch between a state suitable for cleaning dirt on the flooring and a state suitable for using it for removing pet hair adhering to the carpet.

The dual-purpose mop 1 according to the present invention is a paper in which disposable paper P is put on a plurality of cleaning convex portions 12d and both ends of the paper are overlapped on the upper surface of the mop head 10 when cleaning the dirt on the surface of the flooring. When the tubular lock member 36 is pulled up to the first position and locked by the pinching tool 40, the two-dimensional rotary joint 32 is unlocked. , The mop head 10 of the operation rod 20 can be rotated in a plane perpendicular to the longitudinal direction of the oblong rectangular plane. Therefore, if the operation rod 20 is moved in the push-pull direction and the dirt on the flooring is wiped off with the disposable paper P, the lower surface of the mop head 10 is operated so as to be in close contact with the flooring surface when the operation rod 20 is moved in the push-out direction. The tilt angle of the rod 20 with respect to the mop head 10 changes in a smaller direction, and conversely, when the rod 20 is moved in the direction of pulling the operation rod 20, the tilt angle of the operation rod 20 with respect to the mop head 10 changes in a larger direction. It will be in a suitable condition for cleaning dirt.

In particular, in this embodiment, since the two-dimensional rotary joint 32 is adopted for the connecting structure 30, when wiping a narrow place, for example, when wiping around the legs under the desk, for example, when wiping a narrow place, As shown in FIG. 13, the longitudinal direction of the mop head 10 can be aligned with the direction of the operating rod 20 and reciprocated as shown by the arrow C for wiping and cleaning. At this time, when the first rotating body 33 of the two-dimensional rotary joint 32 is rotated so as to rise from the lateral position, the shaft portion 33b abuts on a protrusion (not shown) at the position directly above and is stopped by the bracket 31. Since the second rotating body 34 can rotate in the vertical plane while the first rotating body 33 stands up vertically, the operating rod 20 coincides with the longitudinal direction of the mop head 10. The rotation is compensated in the vertical direction, and the mop head 10 is brought into close contact with the flooring, and the operation rod 20 is moved back and forth for easy cleaning.

Further, when the tubular lock member 36 is pulled down to the second position without using the disposable paper P when used for removing the hair of the pet adhering to the carpet, the tubular lock member 36 is rotated two-dimensionally. By covering the moving joint 32 and externally fitting it to the bracket 31, the rotation of the mop head 10 in the longitudinal direction and the lateral direction is locked with respect to the mop head 10 of the operating rod 20, and the rotation of the mop head 10 with respect to the operating rod 20 is locked. The tilt angle θ is fixed at a predetermined angle. Therefore, it is in a state suitable for cleaning to remove pet hair adhering to the carpet. Therefore, grasp the handle (upper end) and the middle portion of the operation rod 20 with both hands, apply the mop head 10 to the carpet, and pull the operation rod 20 so that the mop head 10 is kept in close contact with the carpet. You can easily perform repetitive movements of moving to, lifting and returning to the original position, and you can remove the pet's hair.

Since the dual-purpose mop 1 according to the present embodiment is provided with the paper holding tool 40, when cleaning the dirt on the surface of the flooring, the disposable paper P is applied to the lower surface portion of the mop head 10 and a plurality of cleaning protrusions are applied. When the paper holding tool 40 holds both ends of the disposable paper P which covers the portion 12d and the both ends of the paper are overlapped on the upper surface of the mop head 10, the operation rod 20 is pushed and pulled, and the disposable paper P presses and pulls the surface of the flooring. Can be wiped clean.

Further, in the dual-purpose mop 1 according to the present embodiment, each cleaning convex portion 12d is W-shaped when viewed from the front direction, and the tubular lock member 36 is on the side where the two W-shaped valleys 12e are located. Since it coincides with the inclined side of the operation rod 20 with respect to the mop head 10 when it is in the position of 2, when it is used to remove the pet hair adhering to the carpet, the disposable paper P is not used. Grasp the handle (upper end) and middle part of the operation rod 20 with both hands, apply the mop head 10 to the carpet, and move the operation rod 20 in the pulling direction so that the mop head 10 is kept in close contact with the carpet. Then, by repeating lifting and returning to the original position, each cleaning convex portion 12d has a function of scraping the side of the two W-shaped valleys 12e, and the pet's hair can be effectively removed.

Further, in the dual-purpose mop 1 according to the present embodiment, the mop head 10 is a combination of the upper surface side member 11 which is a synthetic resin molded body and the lower surface side member 12 which is a rubber molded body, and a plurality of mop heads 12 are formed on the lower surface side member 12. Since the cleaning convex portion 12d of the above is integrally molded, the upper surface side member 11 serves as a holding material, and the lower surface side member 12 can be held in a stable elongated rectangular shape.

Further, in the dual-purpose mop 1 according to the present embodiment, since the upper surface side member 11 has the flange portion 11a and the lower surface side member 12 has the adhered portion 12b, the lower surface side member 12 is separated from the upper surface side member 11. The upper surface side member 11 can hold the oblong rectangular annular adhered portion 12a of the lower surface side member 12 so as not to prevent it.

Furthermore, in the dual-purpose mop 1 according to the present embodiment, since the paper holding tool 40 has an opening 11d and a holding surface-like portion having a saw blade-shaped slit 42, the upper surface side member 11 and the lower surface side member are provided. By utilizing the gap between 12 and 12, the paper holding tool 40 can be provided in a space-saving and simple configuration.
