FIG. 5 is a perspective view schematically showing the portion 24, and FIG. 5 is a schematic view of the locking portion 50 of the first head portion 22 of the mop 10 according to the embodiment of the present invention. FIG. 6 is a cross-sectional view, and FIG. 6 is a cross-sectional view taken along the line YY ′ in FIG.

  The first head portion 22 in FIG. 3 is a perspective view of the second surface 22b, which is an attachment surface that comes into contact with or faces the wiping cloth 70 in a use state during cleaning, as viewed from below. A large number of thin plate-like reinforcing portions 25 extending in the short direction B parallel to the short sides 232 and 233 are formed on the second surface 22 b along the first long side 230. The lower end of the reinforcing portion 25 comes into contact with the wiping cloth 70 in a use state at the time of cleaning, and the wiping cloth 70 can be reliably pressed against the surface to be cleaned by supporting the wiping cloth 70. On the first long side 230 side of the second surface 22b, a large number of engaging protrusions 62 of the wiping cloth attaching portion 60 are formed to protrude.

  The third long side 231 of the first head portion 22 includes a plurality of rotating pins 26 that are formed to protrude along the rotation axis O and two curved arm portions that constitute a part of the locking portion 50. 51, 51 are formed. The curved arm portions 51, 51 are provided on both sides of the connecting portion 30 formed at the center of the third long side 231, extend downward from the third long side 231, and then reverse at the curved portion. It is formed in a tongue shape extending upward. As shown in FIG. 5, a vertically long protrusion 54 extending in the vertical direction, that is, from the first surface 22a side to the second surface 22b side is formed on the surface of the curved arm portion 51 opposite to the connecting portion 30 so as to protrude. Has been. The curved arm portions 51 and 51 are flexible enough to be easily deformed when a person pinches with a finger and pushes the curved arm portions 51 and 51 toward each other. Further, the protrusion 54 is formed more gently on the inclined surface on the third long side 231 side than on the inclined surface on the first long side 230 side, and is easily changed in the opening direction of the mop head 20. Is hard to change in the closing direction.

  In FIG. 4, the second head portion 24 is a perspective view of the second surface 24b, which is an attachment surface that comes into contact with or faces the wiping cloth 70 when used in cleaning, as viewed from below. Similar to the first head portion 22, a large number of reinforcing portions 25 are formed on the second surface 24b, and a large number of engaging protrusions 62 are formed on the second long side 234 side. A plurality of bearing holes 28 are formed along the rotation axis O on the fourth long side 235 side, and engage with the rotation pin 26 of the first head portion 22 so that the first head portion 22 can be engaged. The 2nd head part 24 can be connected rotatably. Further, on the third long side 231 of the second head portion 24, a groove forming portion 55, in which a groove portion 56 is formed at a position facing the protrusions 54, 54 when connected to the first head portion 22, 55 is projectingly formed.

  As shown in FIG. 6, the groove portion 56 includes three groove portions 56 </ b> A, 56 </ b> B, and 56 </ b> C extending in three directions from the vicinity of the center of the groove forming portion 55. The groove portions 56 </ b> A, 56 </ b> B, 56 </ b> C can receive and lock the protrusion 54, and can restrict the first head portion 22 from rotating around the rotation axis O with respect to the second head portion 24. In the grooves 56A and 56B, the inclined surface on the second long side 234 side is formed more gently than the inclined surface on the fourth long side 235 side. In the groove 56C, the inclined surface on the fourth long side 235 side is formed more gently than the inclined surface on the second long side 234 side. Therefore, by engaging the grooves 56A, 56B, and 56C with the inclined surface of the protrusion 54, the protrusion 54 is difficult to move in the direction in which the mop head 20 is closed, and the protrusion 54 in the direction in which the mop head 20 is opened. Is easy to move. When the protrusion 54 indicated by the dotted line in FIG. 6 is positioned in the groove 56A, the mop head 20 can be maintained in the open state as shown in FIG. And if the protrusion 54 is located in the groove part 56C, as shown in FIG. 2, the mop head 20 can be maintained in a closed state. When the protrusion 54 is positioned in the groove 56B, the mop head 20 as shown in FIG. 7 to be described later can be maintained in an open state at the intermediate stop position.

  The groove portions 56A, 56B, and 56C and the protrusion 54 are engagement mechanisms that fix the first and second head portions 22 and 24 in at least three positions of an open state, a closed state, and an intermediate stop position. Is a release mechanism that releases the fixation by the engagement mechanism so that the first and second head portions 22 and 24 can rotate. Further, the curved arm portion 51 is formed so that the projection 54 is biased toward the groove portion 56, and is connected when the first and second head portions 22 and 24 in the closed state are opened by the operator by hand. For example, the protrusion 54 protrudes from the groove 56C and enters the groove 56B, and is fixed so as to press the protrusion 54 against the groove 56B.

  A method of attaching the wiping cloth 70 to the mop head 20 will be described with reference to FIGS. FIG. 7 is a cross-sectional view schematically showing a process of attaching the wiping cloth to the mop according to the embodiment of the present invention. FIG. 8 schematically shows a process of attaching the wiping cloth to the mop according to the embodiment of the invention. FIG. 7 and 8 show the state of the mop head 20 at the intermediate stop position and the open position, using the Z-Z ′ cross section in FIG. 1.

  As shown in FIG. 7, the mop head 20 is fixed from the closed state to the first and second head portions 22 and 24 by the locking portion 50 at an intermediate stop position between the open state and the closed state. The operator spreads it by hand, for example, on the wiping cloth 70 placed on the floor surface 72 and arranges it at a position where the engaging projections 62 come into contact with both ends of the wiping cloth 70. When the operator spreads the mop head 20 by hand, the protrusion 54 of the locking portion 50 moves relatively easily from the groove 56C to the groove 56B, so that the opening operation of the mop head 20 can be easily performed. Since the engagement protrusion 62 has a tapered shape in which the distal end portion 62a extends toward the side opposite to the rotation axis O, when the pressing portion 62 is pressed against the wipe 70 at a predetermined angle as shown in FIG. 70 can be securely engaged. In addition, since the first and second long sides 230 and 234 are curved so that the vicinity of the center protrudes outward, the engagement protrusion 62 near the center is more reliably than the engagement protrusions 62 near both ends. The wipe 70 can be engaged.

  In this state, the mop head 20 is further pressed against the wiping cloth 70 in the direction of the arrow F, so that the distal end portions 62a and 62a are moved in the direction of the arrow G while being engaged with both ends of the wiping cloth 70, so Alternatively, it shifts to an open state as shown in FIG. At the initial stage when the mop head 20 is opened, the engaging protrusion 62 near the center of the first and second long sides 230 and 234 first spreads the wiping cloth 70 and then gradually the first and second long sides 230 and 234. Since the engaging protrusions 62 on both end sides of the two are engaged with the wiping cloth 70, the wiping cloth 70 can be easily attached. Although not shown in FIGS. 7 and 8, when the mop head 20 is in an open state, the protrusion 54 of the locking portion 50 exits the groove 56 </ b> B to the groove 56 </ b> A due to the deformation of the curved arm 51. Fixed by entering.

  By doing so, the engagement protrusion 62 can be reliably engaged with and held by the wiping cloth 70, and the first and second head portions 22 and 24 are fixed at the intermediate stop position. By making it contact with the wiping cloth 70, the wiping cloth can always be attached to the mop head by a certain operation. Further, in the open state of FIG. 8, the first and second head portions 22 and 24 can be reliably maintained in the open state because the protrusion 54 enters the groove portion 56A and is fixed in the locking portion 50. it can. In particular, the engagement protrusion 62 is formed on the outer peripheral edge 23 side facing the rotation axis O of the first and second head portions 22 and 24, whereby the first and second head portions 22 and 24 are formed. When opening about the rotation axis O, the engaging protrusion 62 can attach the wiping cloth 70 to the mop head 20 while applying a certain tensile force to the wiping cloth 70 while spreading the wiping cloth 70.

  The opening angle of the first and second head portions 22 and 24 at the intermediate stop position is about 135 degrees, but the opening angle is appropriately set depending on the engagement state between the engagement protrusion 62 and the wiping cloth 70 at the intermediate stop position. be able to. As shown in FIG. 7, when the short sides 232, 233, 236, and 237 of the first and second head portions 22 and 24 are set as the turning radii, the opening angle is set to be relatively small and the wipe 70 The protrusion tip 62a can be reliably engaged with the end portion. Further, when moving from the intermediate stop position of FIG. 7 to the open position of FIG. 8, the distance to which the wiping cloth 70 is stretched by the protrusion tip 62 is shortened, and an excessive tension is not applied to the wiping cloth 70.

  Further, as shown by dotted lines in FIGS. 7 and 8, for example, a spring 80 is provided as a biasing member that constantly biases the first and second head portions 22 and 24 in the closing direction. Both ends of the spring 80 are held by a spring mounting portion 82 shown in FIGS. 1 and 2. Accordingly, when the first and second head portions 22 and 24 are opened and the release mechanism 52 is deformed to retract the projection 54 from the groove 56A as shown in FIG. The head portions 22 and 24 can be automatically shifted to an intermediate stop position as shown in FIG. 7 or a closed state as shown in FIG. At the time of this transition, the used wiping cloth 70 is detached from the engaging protrusion 62 and can be easily removed. For example, if the release operation by the release mechanism 52 is performed on a trash can, it can be discarded without touching the used wiping cloth 70, which is preferable in terms of hygiene. Note that the protrusions 54 of the locking part 50 and the inclined surfaces of the grooves 54A and 54B are formed so that the mop head 20 is difficult to move in the closing direction, so that the closing operation is performed by operating the release mechanism 52. be able to.

  As shown in FIG. 9, the vicinity of the center of the first and second long sides 230 and 234 is formed in a substantially arc shape in which the wiping cloth mounting surface side, that is, the second surface 22b is concave. In other words, the first and second long sides 230 and 234 are gently curved so that the vicinity of the center is convex upward. As described with reference to FIGS. 1 and 2, since the first and second long sides 230 and 234 have a substantially arc shape that protrudes outward, the first and second long sides 230 are thus formed. , 234 are curved upward, so that the engagement protrusions 62 near the center of the first and second long sides 230, 234 and the engagement protrusions 62 near both ends are wiped at the intermediate stop position as shown in FIG. 70 can be securely engaged.

  In addition, since the tension of the wiping cloth 70 by the engaging protrusion 62 near the center is larger than the tension of the wiping cloth 70 by the engaging protrusion 62 near both ends of the first and second long sides 230 and 234, the wiping is performed. It is easy to attach the cloth 70. As shown in FIGS. 8 and 9, in the open state, the lower end of the engaging protrusion 62 is higher than the lower end of the reinforcing portion 25, and is a surface to be cleaned with the wiping cloth 70 attached, for example, the floor surface 72. When the mop 10 is placed on the floor surface 72, the engagement protrusion 62, in particular, the distal end portion 62a can be prevented from hitting the floor surface 72, and the floor surface 72 can be prevented from being damaged. Further, in the state where the first and second head portions 22 and 24 are opened and the wiping cloth 70 is securely attached, the engaging protrusions 62 near the centers of the first and second long sides 230 and 234 are formed on the floor surface 72. Since the wiping cloth 70 is lifted at a predetermined distance from the trash, the dust on the floor surface 72 can be taken into the interior.

  Although the embodiments of the present invention have been described in detail as described above, many modifications can be made without departing from the novel matters and effects of the present invention.
