A cleaning tool 1 shown in a perspective view in FIG. 1 is composed of a plate 2 and a long handle 4 attached to the plate 2 via a free joint 3. And the disposable dirt wiping sheet 5 whose edge is folded on the upper surface is indicated by a virtual line.

The plate-like body 2 is a rectangular shape which is long in the left and right directions, and is made of a hard plastic body 8 having a pair of long sides 7A and a pair of short sides 7B, and a rubber covering the lower surface and the peripheral edge of the body 8. And the elastic lower surface member 9. Upper surface 1 of main body 8
In FIG. 0, a long handle 4 is attached to a central portion thereof, and clamp members 13 are pivotally attached to left and right side portions. The outer end 15 of the clamp member 13 is formed so as to be grippable, and has a rotating shaft (not shown) that is rotatably engaged with the main body 8 at the inner end 14. When the outer end 15 is pinched and the clamp member 13 is opened in the direction of arrow P, and the edge of the sheet 5 is folded over the main body upper surface 10 and the member 13 is closed, the sheet 5 is clamped between the member 13 and the upper surface 10. Can be.

The long handle 4 is moved by a double-headed arrow Q
As shown by, it is possible to turn about 180 ° in a direction parallel to the long side 7A of the plate-like body 2 and to fall on the plate-like body upper surface 10,
And, as shown by a double-headed arrow R, the short side 7
It can turn about 180 ° in a direction parallel to B and fall on the upper surface 10 of the plate-like body. The long handle 4 is a molded product of a thermoplastic plastic, and has a grip portion 17 and a through hole 18 for suspension at an upper end portion.

The universal joint 3 extends upward from the upper surface 10 of the plate-like body, extends downward from a pair of first support arms 11 facing each other in a longitudinal direction parallel to the long side 7A, and a lower end 4A of the long handle 4. A pair of second support arms 22 opposed to each other in a direction orthogonal to the long side 7A, and are sandwiched between the first support arms 11 and the second support arms 22, and the first support arm 11 and the second support arm And a connecting member 23 interposed between the arm 22 and the arm 22.

FIG. 2 is a view taken in the direction of arrows II-II in FIG. 1, in which the upright long handle 4 is shown by a solid line, and the lying down long handle 4 is shown by an imaginary line. The first support arm 11 and the connection member 23 are rotatably engaged with each other via a rotation shaft 24 extending from each of the first support arms 11 toward the connection member 23, and are connected to the second support arm 22. The members 23 are rotatably engaged with each other via a rotation shaft 25 extending from each of the second support arms 22 toward the connection member 23. The second support arm 22 of the long handle 4 is in the angular range A ₂ is a when the instrument 1 is used in cleaning, parts of the connecting member 23 the second support arm 22 abuts on the case, The thickness of the second support arm 22 is slightly larger than the distance between the opposing second support arms 22, and the second support arm 22 is relatively weakly pressed against the connecting member 23. When support arm 22 enters the range A ₂ moves in a direction to fall down the angle range B _2, coupling member 23 is particularly thick second support arm 22 between the direction of the thickness of the portion 27 which has been subjected a large number of points fine Therefore, the support arm 22 is strongly pressed against the connecting member 23.

FIG. 3 is a view taken in the direction of arrows III-III in FIG. 1, wherein the upright elongated handle 4 and the connecting member 23 are shown by solid lines, and the connecting member 23 that has fallen down with the elongated handle 4 is shown by imaginary lines. ing. The thickness of the connecting member 23 in the direction between the first support arms 11 is larger than the separation dimension of the first support arm 11, and in particular, the portion 26 provided with many fine points is formed particularly thick. When the tool 1 is used, the first support arm 11, like the second support arm 22, is relatively weakly pressed against the connecting member 23, and when the long handle 4 falls down for storing the tool 1, the connecting member 23 The thick part 26 is located between the first support arms 11, and the pressure contact force of the first support arms 11 is increased.

2 and 3, the first and second support arms 11 and
The relatively weak pressing force between the connecting member 2 and the connecting member 23 is set such that the plate-like body 2 can easily swing its head with respect to the long handle 4 when the cleaning worker flexes his arm slightly. On the other hand, the strong pressing force between the first and second support arms 11 and 22 and the connecting member 23 is set to such an extent that the plate-shaped body 2 does not shake its head due to its own weight. When the first support arm 11 and the second support arm 22 are strongly pressed against each other, the plate-shaped body 2 does not shake its head unless an operator particularly applies force.

In the cleaning tool 1 constructed as described above, when the long handle 4 is suspended as shown in FIG. 4 and stored such that the long side 7A of the plate 2 is vertical, the plate 2 becomes heavier. However, it does not turn around the universal joint 3 in the direction of arrow D to become horizontal, and does not occupy much space in the horizontal direction. Therefore, this cleaning tool 1 is convenient when many objects are to be stored in a narrow place. First
It is preferable that both of the two support arms 11 and 22 can be strongly pressed against the connecting member 23, but only one of the two support arms may be strongly pressed.

In the cleaning tool 1 according to the present invention, the plate-like body 2 and the long handle 4 are formed of a relatively elastic plastic such as ABS, and the first and second arms 11, 22 are formed integrally therewith. Is preferred. It is preferable that the connecting member 23 is also formed of the same plastic. Connecting member 23
In, it is preferable that the thickness is gradually changed.

[0018]

In the cleaning tool according to the present invention, when the long handle is in the lying state, the plate-like body does not easily shake the head, and even if the long handle is suspended and stored, the plate-like body can be kept. Does not extend horizontally to get in the way. In addition, the universal joint of such a tool does not have any special members to be added to the conventional joint structure, so that the manufacturing cost can be kept relatively low.
