Composed of standing walls facing the holding section and their hanging walls
And an upright wall provided with engaging projections that engage with each other .

The release means has means for pressing the pair of bases toward each other in a state in which the base is pressed and closed against the cover and the wiping body is gripped between the wiping body gripping portions. Then, the pair of bases are urged in a direction away from each other by an operation lever operable above the cover to release the gripping of the wiping body in the wiping body gripping portions provided on the cover and the base. Is appropriate.

The release means of the mounting head includes a pair of slide members slidably mounted on the cover and urged in a direction opposite to each other by a slide function, and these slide members are located above the cover. And an operating lever, an engagement / disengagement operation section and an opening / pressing section, and a pair of bases includes a driven section to which the engagement / disengagement section is engaged and a pressure-receiving protrusion pressed by the opening / pressing section. With the sliding of the slide member due to the pressing of the operating levers, the engaging / disengaging operation part moves the base in a direction to separate the bases from each other via the driven part, and the opening pressing part presses the pressure receiving protruding part. Is released, and the engagement of the wiping body gripping portions provided on the cover and the base can be released.

[0007]

In the mop handle having the above structure, when the cover and the pair of bases are unlocked, these bases hang down from the cover by their own weight. In this state, when the ends of the wiping body are temporarily fixed to the outer ends of the pair of bases and the base is pressed and closed on the lower surface of the cover, the engaging projections on the wiping body gripping portions provided on the cover and the base are engaged. Together, the base is engaged with the cover, and the wiping body is firmly attached to the mounting head by these wiping body grips. Therefore, during the cleaning operation, the wiping body does not come off from the mounting head or its mounting posture does not shift. The wiping member can be attached only by simultaneously or individually closing a pair of bases to which the ends of the wiping member are temporarily fixed, and engaging the wiping member gripping portion with the wiping member gripping portion of the cover. Is easy.

When the engagement of the engaging projections on the wiping member gripping portions provided on the base and the cover is released by the releasing means, the pair of bases hang down from the cover due to their own weight and the weight of the wiping member attached thereto. The wiping body can be removed from. Since the release means can be operated above the cover, the wiping body can be easily removed and the hands are not stained.

More specifically, when the operating levers projecting above the covers of the pair of slide members are mutually pressed in a state where the engaging projections of the wiping body gripping portions provided on the cover and the base are engaged with each other. The engagement / disengagement operation portion of the slide member engaged with the driven portion of the base presses the base slightly outward to release the engagement between the cover and the wiping body gripping portion of the base and release the slide member. Since the pressing portion presses the pressure receiving projection of the base in the opening direction, the pair of bases hang down from the cover.

[0010] Further, the wiping body gripping portion for gripping the wiping body is provided with:
Since the inward and outward engaging projections engage with each other by closing the base, the wiping body can be more firmly gripped by these wiping body gripping portions.

An open pressing portion 26 is provided on the side. An inclined surface 26a that is inclined toward the bottom surface of the cover 4 and a flat surface 26b with a smaller height at the distal end are formed on the distal end side of the opening pressing portion 26 (see FIG. 8). A central projection 27 extending in the sliding direction is provided at the center of the rear surface of the slide member 6, a spring shaft 28 is provided on the end surface on the distal end side, and a cover is formed through the slide groove 11 on the upper surface. 4
Operation levers 29 projecting upward are provided, respectively.

The bottom wall 5a of the base 5 is slidably inserted with an engaging / disengaging operation portion 25 of the slide member 6 when the base 5 is closed to the cover side. Are formed with a trapezoidal groove-shaped driven portion 20 whose width is smaller than the width of the opening, and a pressure-receiving protrusion 21 whose upper surface is an arc surface facing outward. Further, a claw for temporarily fixing the wiping body 2 is formed on the bottom wall 5 a side of the tip of the temporary fixing claw 19.

The slide member 6 is mounted on a spring shaft 28, and is urged in a direction opposite to each other by a slide spring (coil spring) 30 contracted between the spring member 13 and an operating lever. The movement of the slide groove 11 is restricted by the contact of the slide groove 11 with the end face of the slide groove 11. When the base 5 is pressed against the cover 4 and closed, the engagement / disengagement operation portion 25 is engaged with the driven portion 20 of the base 5, but the engagement / disengagement operation is performed by the urging force of the slide spring 30. The base 5 is pressed in a direction in which the bases 5 approach each other by a force acting on the driven part 20 from the part 25, thereby urging the engaging projections 9, 18 provided on the wiping body gripping part in a direction in which they engage with each other. Is done. In addition, when the base 5 is pressed and closed to the cover 4, the flat surface 26 b of the opening pressing portion 26 is related to the pressure receiving protrusion 21.

A handle mounting body 33 (see FIGS. 1 and 2) for mounting the handle 32 is provided with a handle mounting portion 12.
The handle 32 is attached so as to click at predetermined angles with respect to the mounting holes (not shown) of the handle mounting portions 12, 12. (Omitted) mounting pin 34

As shown in FIG. 2, the wiping body 2 mounted on the mounting head 1 has a large number of wiping threads 2b on a base cloth 2a.
It is configured as the one planted. Further, the cover 4, the base 5, the slide member 6, and the handle mounting body 3
3 are integrally formed of an appropriate synthetic resin, respectively, and the pair of bases 5 and 5 and the slide members 6 and 6 have the same shape.

Before attaching the bases 5 to the cover 4, the slide members 6, 6 are assembled so that the operation lever 29 projects upward from the slide groove 11 so as to be slidable between the hanging walls 8a, 8a. These slide members 6,
6 is urged by slide springs 30 and 30 in directions opposite to each other (see FIGS. 3 and 4). The bases 5, 5 are pivotally attached to the cover 4 so as to be able to move slightly outward by inserting the pivot shafts 16 into the pivot portions 10, 10 through the insertion openings 10a, respectively, as shown in FIG. As shown, it is made to hang down from the cover 4 by its own weight.

In the state where the bases 5 and 5 are suspended from the cover 4, the mounting head 1 holds the end of the base cloth 2 a of the wiping body 2 under the temporary fixing claws 19 provided on these bases 5. When the bases 5 and 5 are pressed and closed toward the cover 4, the engaging projections 9 and 18 provided on the cover 4 and the bases 5 and 5 are engaged, and the bases 5 and 5 are covered. 4
And the wiping body 2 is firmly gripped by this (see FIG. 2). Therefore, while having a very simple configuration, the wiping body 2 does not come off from the mounting head 1 or the mounting posture is not shifted during cleaning of a floor surface or the like. When the base 5 is closed, the engagement / disengagement operation section 25 of the slide member 6 is slidably inserted into the driven section 20 of the base 5, so that the wiping body is gripped by the wiping body gripping section and the opening pressing section is held. The flat surface 26 b of the base 26 faces the pressure receiving projection 21 of the base 5.

When replacing the dirty or worn wiping body 2, the operation lever 2 projecting above the cover 4 is replaced.
9 are pressed against each other against the urging force of the slide spring 30, the disengagement operation unit 2 that is inclined obliquely outward of the slide member 6.
5 pushes the driven portion 20 to move the base 5 outward, so that the engagement of the engagement projections 9 and 18 provided on the wiping body gripping portion between the cover 4 and the bases 5 and 5 is released. . At the same time, the opening pressing portion 26 of the slide member 6 presses the pressure receiving projection 21 of the base 5 to open the base.
In this case, since the inclined surface 26a exists between the flat surface 26b and the opening pressing portion 26, the movement of the slide member 6 is smooth.

By disengaging the engagement projections 9 and 18 and pressing the base 5 by the release pressing portion 26, these bases 5 hang down from the cover 4 due to their own weight and the weight of the wiping body 2 attached thereto. Therefore, the wiping body 2 can be dropped from the head 1 or can be easily removed. This operation of removing the wiping member can be performed above the cover 4 and it is not necessary to directly touch the dirty wiping member 2, so that the operation is simple and the hands are not stained. After removing the dirty or worn wiping body 2, a new wiping body can be attached to the head 1 by the above-described operation.
