The second connection member 17 is connected to the connection pin 19c and the base end 22a of the lock lever 22 by being provided above the cylindrical portion 2e of the inner peripheral surface of the reinforcing sleeve 2d. Since the cylindrical portion 2e is provided at a position closer to the upper end side of the handle 2 than the connecting pin 19c, when the connecting pin 19c moves downward, the base end 22a of the lock lever 22 is pulled up by the second connecting member 17, When the linking pin 19c moves upward, the slackening of tension by the second linking member 17 enables the rocking by the return spring of the lock lever 22, that is, the lowering of the base end 22a of the lock lever 22. In addition, the description of the 2nd connection member 17 is abbreviate|omitted in FIGS. 8-11.

Next, the switching operation of the locking means 4 will be described. When the operating sleeve 18 of the closing direction operating means 12 is slid to the unlocking position shown in FIGS. 1(A) , 8 , and 10 , the second connecting member 17 of the locking means 13 swings the locking lever 22 . Therefore, the pawl 22b is disengaged from the arm 7 (lock release). At the same time, since the tension of pulling the wings 8 of the left and right locking means 4 toward the first connecting member 16 on the cleaning tool 1 side is loosened, the first elastic member 11a and the second elastic member 11b of the means 11 are operated by the opening direction. The elastic thrust of the force causes the locking means 4 to open.

On the other hand, when the operation sleeve 18 is slid to the locked position shown in FIGS. 1(B), 9, and 11, the wings 8 of the left and right locking means 4 are moved toward The side of the head 3 is pulled closer, and the locking means 4 on the left and right are folded. At the same time, the second coupling member 17 is loosened and the rocking of the lock lever 22 is enabled. Therefore, the lock lever 22 is rocked by a return spring (not shown), and the claw 22b locks the arm 7 . Thereby, the locking means 4 on the left and right are locked in a closed state.

In this way, the locking means 4 can be opened and closed by sliding the operation sleeve 18 .

Next, the mounting of the head 3 in the direction of the cleaning sheet 9 will be described. In the cleaning tool 1 of the present invention, when the head 3 is placed above the cleaning sheet 9 and the locking means 4 is moved from the open state to the closed state by the operation means 5, the locking means 4 can be The portion 9a of the cleaning sheet 9 protruding from the head 3 is hooked, moved upwards of the head 3, and locked. That is, since the cleaning sheet 9 is spread and placed on the floor, the user of the cleaning tool 1 can then attach the cleaning sheet 9 to the bottom surface of the head 3 without contacting the cleaning sheet 9 or the head 3 .

When the operation sleeve 18 of the closing direction operation means 12 is slid to the unlocked position, the second connection member 17 of the lock means 13 swings the lock lever 22 . Thereby, the claw 22b is disengaged from the arm 7 (lock is released), and the locking means 4 is opened by the opening direction operating means 11 .

In this state, when the cleaning tool 1 is placed above the cleaning sheet 9 spread out on the floor, the hooking member 10 provided on the bottom surface of the wing portion 8 moves from the head 3 of the cleaning sheet 9 to the side The square protruding part (protruding part) 9a is hooked (FIG. 15(B)). At this time, since the head 3 is placed on the cleaning sheet 9, the wings 8 are slightly returned in the closing direction from the state shown in FIG. 2. The elastic force of the elastic member 11b and the hook member 10 can strongly press the cleaning sheet 9. Therefore, the hook member 10 hooks the cleaning sheet 9 stably.

In this state, when the user slides the operating sleeve 18 of the closing direction operating means 12 upward, the left and right wings 8 can be moved toward the head 3 side by the first connecting member 16, and the left and right latches can be moved. Stop means 4 are folded (closed state). At this time, the left and right wing portions 8 are pushed by the second elastic member 11b toward the opening direction, that is, the floor, and the left and right wing portions 8 slide on the floor while sandwiching the cleaning sheet 9 between the floor and the head 3 . Further, it is placed on the cover-shaped member 3b of the head 3 and moved. By this movement, the protruding portion 9 a of the cleaning sheet 9 is moved above the head 3 . Next, when the left and right locking means 4 are folded, the protruding portion 9a of the cleaning sheet 9 is firmly sandwiched between the wing portion 8 and the arm 7 (FIG. 15(C)). That is, the locking means 4 locks the protruding portion 9 a of the cleaning sheet 9 . Thereby, the cleaning sheet 9 can be attached to the head 3 .

The left and right locking means 4 are in a closed state, and when the operation sleeve 18 is slid to the locked position, the cleaning sheet 9 is firmly sandwiched between the locking means 4 and the head 3 . At the same time, the lock lever 22 locks the arm 7 . Thereby, the locking means 4 is locked, and even if the user releases his hand from the operation sleeve 18, the left and right locking means 4 can maintain the state in which the protruding portion 9a of the cleaning sheet 9 is sandwiched. In this state, the user can use the cleaning tool 1 to clean.

When replacing the cleaning sheet 9 after use, it is sufficient to lower the operation sleeve 18 to release the locking of the locking means 4 . When the user lowers the operation sleeve 18 , the second coupling member 17 swings the lock lever 22 to disengage the pawl 22 b from the arm 7 . Thereby, the latching means 4 on the left and right are opened by the urging force of the opening direction operating means 11, and the protruding portion 9a of the cleaning sheet 9 is released, whereby the cleaning sheet 9 can be removed and replaced. For example, if the operation sleeve 18 is slid to the unlocked position in a state where the head 3 is moved over the trash can (not shown), the cleaning sheet 9 after use can be dropped into the trash can without touching it. The used cleaning sheet 9 is discarded as it is.

In this way, in the cleaning tool 1 of the present invention, the cleaning sheet 9 can be replaced without contacting the cleaning sheet 9 or the head 3 . Therefore, the replacement of the cleaning sheet 9 is extremely simple and hygienic.

In addition, the above-mentioned embodiment is an example of the form suitable for carrying out this invention, and it is not limited to this, Various deformation|transformation can be implemented in the range which does not deviate from the summary of this invention. For example, in the above description, the cleaning sheet 9 is not The protruding portion 9a of 9 may be sandwiched between the wing portion 8 of the locking means 4 and the head 3, or between the arm 7 and the head 3. Even in these cases, the cleaning sheet 9 can be stably attached to the head 3 . [Industrial Availability]
