FIG. 11 is a schematic view showing a state in which the cleaning sheet is caught with respect to the anti-slip portion of the mounting plate.

  As shown in FIGS. 1 and 2, the cleaning tool 1 has a proximal end portion of the angle adjustment arm 200 connected to the most distal end portion of the rod-like tool 100, and a cleaning head via a head joint 300 at the distal end portion of the angle adjustment arm 200. 400 is connected, and the cleaning sheet 500 is attached to and detached from the mounting plate 401 of the cleaning head 400 for use.

  The rod-shaped tool 100 is formed by connecting a plurality of shafts 10 to 40 in a freely stretchable manner, and FIGS. 1 and 2 show the most contracted state. The first shaft 10 constitutes a grip 11 that is gripped by the user in the cleaning tool 1.

  The angle adjustment arm 200 can be used by adjusting the mounting angle of the cleaning head 400 connected to the rod-shaped tool 100.

  The head joint 300 connects the cleaning head 400 to the tip of the angle adjustment arm 200. The head joint 300 includes a stainless steel plate spring 301 as shown in FIGS. The base end portion of the leaf spring 301 is inserted into a U-shaped cross-section mounting groove 208 provided on the rear surface on the distal end side of the angle adjustment arm 200, and the set screw 302 is inserted into the flaw hole 301 </ b> A of the leaf spring 301.

Accordingly, the cleaning head 400 can bend flexibly by the head joint 300 and press the entire surface up to the base of the mounting plate 401 against the cleaning surface. Since the cleaning head 400 bends in the vertical direction, the attachment plate 401 can be made to follow the cleaning surface without finely adjusting the crossing angle of the cleaning head 400 with respect to the rod-shaped tool 100.

  The cleaning head 400 uses the mounting plate 401 as a mounting portion for the cleaning sheet 500, and from the front end side of the mounting plate 401 (the side closer to the rod-shaped tool 100 of the mounting plate 401 is the base end side, and the opposite side is the front end side). When the cleaning sheet 500 is inserted, the mounting plate 401 has a wide end 401A at the base end, a narrow end 401B at the distal end, and left and right stepped locking portions 401C at the boundary between the wide end 401A and the narrow end 401B. . In this embodiment, the wide portion 401A is longer in the insertion direction of the cleaning sheet 500 than the narrow portion 401B.

  The cleaning head 400 is provided with a sheet holding projection 404 (holding portion) that holds one end portion of the cleaning sheet 500 on the base end side of the mounting plate 401, in this embodiment, on the base side of the upper surface of the wide width portion 401A. A non-slip portion 405 that is in frictional contact with the bag-shaped inner surface of the cleaning sheet 500 is provided on the front end side of the 401, in the present embodiment, on the lower surface (also provided on the upper surface) of the narrow width portion 401B.

  The cleaning sheet 500 includes, for example, a base nonwoven fabric 501A and fibers 501B on the surface of the base nonwoven fabric 501A. The cleaning sheet 500 overlaps two base nonwoven fabrics 501A in a cylindrical shape penetrating on an extension line in a direction of being attached to the mounting plate 401 so as to form a bag shape at both ends so that the cleaning sheet 500 can be attached to the mounting plate 401. Left and right side seals 502 (linear seals or juxtaposed dot seals) are provided, and left and right steps provided at the boundary between the wide portion 401A and the narrow portion 401B of the mounting plate 401 on the left and right sides of the middle portion in the longitudinal direction. A point seal 503 is provided to be hooked on the locking portion 401C. The cleaning sheet 500 includes a locking hole 504 that is locked to the sheet holding projection 404 of the mounting plate 401 at the center of both ends in the longitudinal direction of the base nonwoven fabric 501A.

  The cylindrical base nonwoven fabric 501A of the cleaning sheet 500 is inserted into the mounting plate 401 of the cleaning head 400, the point seals 503 on both sides are hooked on the left and right locking portions 401C of the mounting plate 401, and the locking holes 504 are mounted on the mounting plate. The sheet holding projection 404 is used by being locked. At this time, the sheet holding projection 404 of the cleaning head 400 has a head portion 404A connected to the base side of the upper surface of the wide portion 401A of the mounting plate 401 via the projection shaft portion 404B, as shown in FIGS. The head 404A has a vertically long shape longer than the locking hole 504 of the cleaning sheet 500 in the insertion direction of the cleaning sheet 500 in a plan view, and is provided with a tapered surface 404C on the lower surface of the sheet insertion side. 504 passes through the head 404A and is locked to the protruding shaft 404B, so that the locking hole 504 of the cleaning sheet 500 is easily inserted and is not easily detached. Further, the sheet holding projection 404 is provided with a projection shaft portion 404B at a position shifted to the base end side of the mounting plate 401 from the central portion of the longitudinal length along the insertion direction of the cleaning sheet 500 in the head portion 404A. As a result, the sheet holding projection 404 passes through the sheet insertion side with respect to the projection shaft portion 404B, thereby facilitating insertion of the locking hole 504 of the cleaning sheet 500. Then, the sheet holding projection 404 makes the maximum circumferential length of the head portion 404 </ b> A through which the locking hole 504 of the cleaning sheet 500 passes equal to or less than the circumferential length of the locking hole 504. That is, in FIGS. 6 and 7, the longitudinal length of the sheet holding projection 404 is A, the maximum circumferential length of the projection 404 passing through the outer peripheral surface of the projection shaft portion 404B on the sheet insertion side is L, and the vertical direction of the locking hole 504 When the length is a and the circumferential length is l, l × γ> L (γ is an elongation correction coefficient of the base nonwoven fabric 501A) so that the locking hole 504 of the cleaning sheet 500 is inserted into the sheet holding protrusion 404. By making a << A, the locking hole 504 of the cleaning sheet 500 is not easily detached from the sheet holding projection 404.

  As shown in FIGS. 8 to 11, the anti-slip portion 405 provided on the mounting plate 401 of the cleaning head 400 is a protrusion assembly 406 provided on the lower surface of the narrow width portion 401B, and each protrusion 407 is, for example, a short circle. A side surface 407A that rises from the lower surface of the narrow portion 401B in a columnar shape and a top surface 407B (FIGS. 10 and 11) intersecting the side surface 407A, the side surface 407A is formed smoothly and without corners like a cylindrical outer peripheral surface, The intersection of the side surface 407A and the top surface 407B is formed in a square shape. Each protrusion 407 of the non-slip portion 405 can be made of a high friction material (rubber, brushed fabric, etc.) provided integrally or separately on the lower surface of the narrow width portion 401B.

  Therefore, in the cleaning tool 1, the point seal 503 that forms a narrow hooking portion is provided in the middle portion of the insertion range of the cleaning sheet 500 with respect to the cleaning head 400, and the cleaning sheet 500 attached to the mounting plate 401 is provided. While the point seal 503 is hooked on the stepped locking portion 401C of the mounting plate 401, the locking hole 504 at one end of the cleaning sheet 500 is held by the sheet holding projection 404 of the mounting plate 401, and the cleaning sheet 500 Is prevented from slipping by a non-slip portion 405.

According to the present embodiment, the following operational effects can be obtained.
(a) In the cleaning tool 1, the anti-slip portion 405 of the mounting plate 401 prevents the cleaning sheet 500 from slipping when the cleaning sheet 500 is pressed against the anti-slip portion 405 by the cleaning reaction force from the surface to be cleaned. Therefore, when the cleaning sheet 500 is inserted into the attachment plate 401, the anti-slip portion 405 does not become a resistance against the cleaning sheet 500.

  (b) At the time of cleaning with the cleaning sheet 500 attached to the mounting plate 401, one end of the cleaning sheet 500 is held by the sheet holding protrusion 404 on the base end side of the mounting plate 401, and the cleaning sheet 500 is attached to the mounting plate 401. It is prevented from slipping by the anti-slip portion 405 on the tip side. Therefore, the cleaning sheet 500 is stably and reliably inserted without moving with respect to the mounting plate 401.

  (c) The anti-slip portion 405 of the mounting plate 401 is a projection assembly 406, and the projection 407 includes a side surface 407A rising from the mounting plate 401 and a top surface 407B intersecting the side surface 407A. The intersection of the side surface 407A and the top surface 407B is formed in a square shape. Therefore, the cleaning sheet 500 is prevented from slipping by engaging with the angular intersection between the side surface 407A of the protrusion 407 and the top surface 407B. Further, since the side surface 407A of the protrusion 407 is formed smoothly and without corners, the user's fingers are not damaged.

  (d) The mounting plate 401 has a wide end 401A on the base end side and a narrow end 401B on the distal end side, and a stepped locking portion 401C is provided at the boundary between the wide end 401A and the narrow end 401B. By holding one end of the cleaning sheet 500 on the sheet holding projection 404 on the base end side of the mounting plate 401 in a state where the intermediate portion of the cleaning sheet 500 is locked to the stepped locking portion 401C of the mounting plate 401, One end portion to an intermediate portion of the cleaning sheet 500 can be stably and reliably inserted into the mounting plate 401. In addition, the intermediate portion to the other end portion of the cleaning sheet 500 can be prevented from slipping to the slip preventing portion 405 of the mounting plate 401.

  (e) When the tubular nonwoven fabric 501A of the cleaning sheet 500 is inserted into the attachment plate 401, the entangled portion of the fibers constituting the nonwoven fabric 501A is hooked and engaged with the protrusions 407 constituting the anti-slip portion 405 to ensure that It is slippery (FIG. 11).

  (f) Since the cleaning sheet 500 forms a through-hole, the cleaning sheet 500 can be inserted into the mounting plate 401 of the cleaning tool 1 from either end of the cleaning sheet 500. Since the front end portion of the cleaning sheet 500 is easily soiled and the root portion is not easily soiled, it can be inserted from either side. Also in this case, since the cleaning sheet 500 is prevented from slipping on the mounting plate 401 and is maintained in a stable and reliable insertion state, the tip of the mounting plate 401 may protrude from the tube of the cleaning sheet 500 and touch the surface to be cleaned. There is no.

  (g) The cleaning sheet 500 is securely slipped by the high friction force on the anti-slip portion 405 of the high friction material provided on the mounting plate 401.
