Description

[Technical field]

[0001] The present invention relates to a flooring wiper that cleans floor surfaces by attaching a cleaning sheet to a head. [Background technology]

[0002] 2. Description of the Related Art Floor wipers that clean floor surfaces by attaching a cleaning sheet to a head are well known in the art. In such floor wipers, various fixing mechanisms are used to fix the sheet to the head.

[0003] For example, Patent Document 1 discloses a floor wiper in which a plurality of elastic tongues 18a-18f are provided by providing a plurality of intersecting slits at the four corners of the upper surface of the head 10. When fixing a cleaning sheet 22 to the head 10, the end of the sheet 22 is pushed into the slits and engaged with the elastic tongues 18a-18f while covering the lower surface of the head 10 with the sheet 22, and the sheet 22 is fixed. When removing the sheet 22 from the head 10, the end of the sheet 22 is pulled strongly to pull the sheet 22 out of the slits, so that the sheet 22 can be removed. However, the floor wiper disclosed in Patent Document 1 requires the sheet 22 to be replaced by directly touching it with one's hands, and thus, although a new sheet 22 is attached, when removing the dirty sheet 22 from the head 10 after cleaning, one's hands become dirty, which is problematic in terms of hygiene.

[0004] Meanwhile, Patent Document 2 discloses a flooring wiper 1 equipped with a sheet 2 with a spatula for removing wax. The flooring wiper 1 has a fixing member 10 connected to the head 4 at both longitudinal ends of the top surface of the head 4 so as to be able to rise and fall freely, and a protrusion protruding downward from the end of the fixing member in the longitudinal direction. 11 The projection is provided. 11 is configured to fit into a locking hole 12 opened on the top surface of the head 4. . beforeWhen the sheet 2 is fixed to the head 4, the lower surface of the head 4 is covered with the sheet 2, the fixing member 10 is tilted down to interpose the end of the sheet 2 between the fixing member 10 and the head 4, and the protrusion 11 is fixed by fitting it into engagement hole 12 through mounting hole 26 of sheet 2. Furthermore, in the flooring wiper 1, knob 13 is provided at the tip of fixing member 10, and fixing member 10 can be raised or lowered by holding knob 13 with the hand. However, when sheet 2 is fixed to head 4, knob 13 is in contact with sheet 2, so that when sheet 2 is removed, soiled sheet 2 comes into contact with the hand, and as with the device of Patent Document 1, it can be said that there is room for improvement in terms of hygiene.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] A flooring wiper according to the present invention will be described with reference to Figs. 1 to 13. The flooring wiper 1 has a handle 2 and a rectangular head 3 attached to the end of the handle 2. A cleaning sheet 4 is attached to the head 3 so as to cover the entire underside of the head 3, and the head 3 is pressed against the floor surface of a toilet, living room, etc. to perform cleaning.

[0015] The sheet 4 is a rectangular flexible sheet made of nonwoven fabric, woven fabric, etc. The sheet 4 may be a wet type that contains liquid such as water or detergent, or a dry type that does not contain liquid, depending on the cleaning purpose.

[0016] The handle 2 is a round bar-shaped member. The handle 2 is provided with a grip 2a at its base end, and a universal joint 5 that can tilt in the front-rear and left-right directions is attached to its tip. The handle 2 is connected to the head 3 via the universal joint 5 so that it can tilt at any angle in the front-rear and left-right directions. The handle 2 may be formed to be extendable so that its length can be adjusted.

[0017] The head 3 has a cushioning pad 6 on which the seat 4 is attached and which has a left-right length longer than its front-to-back length, a head base 7 fixed to the front-to-back and left-to-right central portion of the upper surface 6a of the cushioning pad 6, with a front portion FA and a rear portion BA of the upper surface 6a at the outer periphery of the cushioning pad 6 exposed, a first sheet holding member 20A provided at the front end portion in the front-to-back direction of the head base 7, and a second sheet holding member 20B provided at the rear end portion.

[0018] The buffer pad 6 is a plate made of synthetic resin foam and has cushioning properties during cleaning. As shown in Figures 4 and 5, the buffer pad 6 has a plurality of circular holes 6b penetrating in the thickness direction, and a plurality of circular protrusions 8 provided inside (back side) of the head base 7 and protruding downward are fitted into the circular holes 6b, thereby fixing the buffer pad 6 and the head base 7 to each other. The buffer pad 6 has a shape in which the center parts 6c of both sides in the front-rear direction are curved inward.

[0019] The head base 7 is a member whose left-right length is longer than its front-rear length, and both left-right ends are rounded by drawing curves. A handle attachment portion 10 for attaching the handle 2 is provided on the upper surface 7a of the head base 7, and this handle attachment portion 10 is disposed in the center of the head base 7 in the front-rear and left-right directions. The handle attachment portion 10 is formed in a convex shape that protrudes upward and has a pair of bearing portions 10a, 10a that receive the universal joint 5. A plurality of ribs 9 are provided inside the head base 7, which reinforce the head base 7 and define a receiving groove 31 and a recess 43, which will be described later.

[0020] 4 and 5, the head base 7 has cutout grooves 11 formed in the front and rear side surfaces 7b, 7c thereof, which communicate with the inside of the head base 7, and the cutout grooves 11 are provided at both ends in the left and right direction of the front and rear side surfaces 7b, 7c. A concave bearing portion 12 is provided inside the head base 7 at a position adjacent to the cutout grooves 11 (see FIGS. 5 and 7).

[0021] The first and second sheet holding members 20A, 20B are for attaching the sheet 4 to the buffer pad 6. Since the first and second sheet holding members 20A, 20B have the same configuration, the first sheet holding member 20A will be described, and unless otherwise required, the second sheet holding member 20B will be given the same reference numeral as the first sheet holding member 20A and a detailed description thereof will be omitted.

[0022] The first sheet holding member 20A is an elongated member having a cross-sectional shape of an inverted U-shape or an inverted V-shape with an open lower portion, or a concave shape similar thereto, and as shown in Figs. 4, 5 and 7, has a base portion 21 extending in the left-right direction along the front side surface 7b of the head base 7 (the rear side surface 7c for the second sheet holding member 20B), and an arc-shaped portion 22 connected to the upper end edge of the base portion 21 and formed so as to draw an outwardly convex arc. The lower end edge 22a of the arc-shaped portion 22 is a portion that holds the sheet 4 between the upper surface 6a of the buffer pad 6, and is provided with a plurality of protrusions 25 for preventing the sheet 4 from slipping when the sheet 4 is held. In addition, a plurality of ribs 26 are arranged at intervals in the left-right direction inside the first sheet holding member 20A to reinforce the first sheet holding member 20A. As shown in FIG. 3, the lower end portion (the lower edge 22a of the arc-shaped portion 22) on the outer side in the front-to-rear direction of the first sheet holding member 20A has an inwardly curved shape in accordance with the central portion 6c of the buffer pad 6 when viewed in a plan view.

[0023] 4 and 7, the first sheet holding member 20A has pivot shafts 27, 27 at both left and right ends. The pivot shafts 27, 27 have arm portions 27a, 27a protruding from the lower end of the base portion 21 toward the second sheet holding member 20B side (the first sheet holding member 20A side in the second sheet holding member 20A), and tip shafts 27b, 27b provided at the tips of the arm portions 27a, 27a. The tip shafts 27b, 27b face each other and protrude outward in the left and right direction.

[0024] And the above arm 27a, 27a are inserted into the head base 7 through the two cutout grooves 11, 11 provided on the front side 7b of the head base 7 (the rear side 7c in the case of the second sheet holding member 20B), and the tip shafts 27b, 27b are journalled on the bearing portions 12, 12 within the head base 7.

[0025] The tip shafts 27b, 27b of the first sheet holding member 20A are concentric with each other, and their centers are configured to be located on the first rotation axis L1 extending in the left-right direction at the front end of the head base 7. On the other hand, the tip shafts 27b, 27b of the second sheet holding member 20B are concentric with each other and are configured so that their centers are located on a second rotation axis L2 extending in the left-right direction at the rear end of the head base 7. These first and second rotation axes L1, L2 extend horizontally and parallel to each other.

[0026] As a result, the first and second sheet holding members 20A, 20B are freely rotatable about the first and second rotation axes L1, L2 extending in the left-right direction relative to the front and rear ends of the head base 7, and can be displaced between an attachment position in which the first and second sheet holding members 20A, 20B clamp the sheet 4 between the exposed front portion FA and rear portion BA of the upper surface 6a of the buffer pad 6, and a release position in which the first and second sheet holding members 20A, 20B are moved away from the buffer pad 6 to release the clamped state of the sheet 4.

[0027] Furthermore, first and second operation pieces 40A and 40B in the form of protrusions are connected to the first and second sheet holding members 20A and 20B, respectively, for use in rotating the first and second sheet holding members 20A and 20B. The first operation piece 40A protrudes from the first sheet holding member 20A toward the rear end (the second sheet holding member 20B side) on the head base 7, and the second operation piece 40B protrudes from the second sheet holding member 20B toward the front end (the first sheet holding member 20A side) on the head base 7. The first sheet holding member 20A and the first operating piece 40A are configured to rotate about the first rotation axis L1 so that when one is pushed downward, the other is lifted upward, and the second sheet holding member 20B and the second operating piece 40B are configured to rotate about the second rotation axis L2 so that when one is pushed downward, the other is lifted upward.

[0028] As shown in Fig. 3, the first and second operating pieces 40A, 40B are disposed closer to one end in the left-right direction than the handle attachment part 10, and the tips 41, 41 of these operating pieces 40A, 40B are adjacent to each other in the left-right direction on the head base 7. In this embodiment, the first operating piece 40A is disposed closer to the handle attachment part 10 than the second operating piece 40B. .Ma Further, a recess 43 is provided on the upper surface 7a of the head base 7 at a position corresponding to the first and second operating pieces 40A, 40B, in which the operating pieces 40A, 40B are accommodated. The recess 43 is a through hole that penetrates the head base 7 in the up-down direction and is partitioned by the rib 9. The recess 43 is composed of a first portion 43a extending from the front side surface 7b of the head base 7 to the rear side surface 7c, and a second portion 43b adjacent to the first portion 43a in the left-right direction and extending from the rear side surface 7c to the front side surface 7b, and these tip portions are connected at the center in the front-rear direction to form a generally crank-like shape in a plan view. The first operating piece 40A is accommodated in the first portion 43a of the recess 43 and is rotated around a first rotation axis L1 within the first recess 43a, and the second operating piece 40B is rotated around the first rotation axis L1 of the recess 43. 2nd partThe first portion 43a and the second portion 43b are accommodated in the second recess 43 and are configured to be rotated about the second rotation axis L2 within the second recess 43. The tip portion where the first portion 43a and the second portion 43b are connected is rounded in an arc shape.

[0029] As shown in Fig. 3 and Fig. 9, the first operation piece 40A and the second operation piece 40B each have a base end 42 connected to the upper end of the base plate portion 21 of the first and second sheet holding members 20A and 20B, and the tip end 41 bent upward at an obtuse angle from the base end 42. The base end 42 is formed in a flat plate shape, and is configured so that its upper surface is flush with the upper surface 7a of the head base 7 when the first and second sheet holding members 20A and 20B are in the mounting position (see Fig. 1). In addition, in the tip end 41, the tip end 41 of the first sheet holding member 20A extends beyond the first rotation axis L1 toward the second sheet holding member 20B, and the tip end 41 of the second sheet holding member 20B extends beyond the second rotation axis L2 toward the first sheet holding member 20A. The upper surface of the tip portion 41 is rounded in an arc shape, and is located lower than the upper end of the handle attachment portion 10 in the vertical direction.

[0030] The first and second sheet holding members 20A, 20B further include a holding mechanism for holding them in the attached position and the released position, which will be described below.

[0031] As shown in Fig. 5 and Fig. 6, the first and second sheet holding members 20A and 20B further have first and second spring mounting parts 28 and 29. The first and second spring mounting parts 28 and 29 are horizontally cylindrical and provided at the center of the base plate parts 21 and 21 of the first and second sheet holding members 20A and 20B in the left-right direction. One end and the other end of a spring member 30 made of a single coil spring that constantly exerts a contraction force are engaged with the spring mounting parts 28 and 29, so that the spring member 30 is tensioned between the first and second sheet holding members 20A and 20B. The contraction force of the spring member 30 constantly acts in a direction that draws the first and second sheet holding members 20A and 20B toward each other. In addition, notches 28a, 29a are provided on the outer peripheral surfaces of the first and second spring mounting portions 28, 29, and one end and the other end of the spring member 30 are engaged with the notches 28a, 29a, thereby suppressing lateral (left-right) displacement of the spring member 30. The spring member 30 is housed in a concave receiving groove 31 formed inside the head base 7. This receiving groove 31 is formed in the left-right center of the head base 7 and is partitioned by the two ribs 9, 9 provided in the left-right center of the head base 7 and extending in the front-rear direction.

[0032] The first and second spring mounting portions 28, 29 rotate about the first and second rotation axes L1 and L2 as the first and second sheet holding members 20A, 20B rotate, respectively, and are displaced upward and downward about the first and second rotation axes L1 and L2, and accordingly, the spring member 30 is also displaced upward and downward within the receiving groove 31. This will be described in detail.

[0033] That is, the first and second spring attachment portions 28, 29 and the spring member 30 are located above the first and second rotation axes L1, L2 when the first and second seat holding members 20A, 20B are in the release position of FIG. 11. 308 in the release position. When the first and second sheet holding members 20A, 20B rotate from this position toward the mounting position, the first and second spring mounting parts 28, 29 rotate around the first and second rotation axes L1, L2 in the direction of the downward dashed arrow in Fig. 13, drawing an outwardly convex arc. Then, when the first and second spring mounting parts 28, 29 and the spring member 30 are positioned below the first and second rotation axes L1, L2, the contraction force of the spring member 30 acting at this position holds the first and second sheet holding members 20A, 20B in the mounting position in Fig. 8 in which they abut against the buffer pad 6.

[0034] Conversely, when the first and second sheet holding members 20A, 20B rotate from the mounting position toward the release position, the first and second spring mounting parts 28, 29 rotate accordingly around the first and second rotation axes L1, L2 in an outwardly convex arc in the direction of the dashed dotted line upward arrow shown in Fig. 13. Then, when the first and second spring mounting parts 28, 29 and the spring member 30 are positioned above the first and second rotation axes L1, L2, the contraction force of the spring member 30 acting at this position holds the first and second sheet holding members 20A, 20B in the release position shown in Fig. 11. In addition, in the attached position, it is clear that the downward rotation of the first and second sheet holding members 20A, 20B is restricted by abutting against the buffer pad 6, but in the released position, the spring member 30 abuts against the top plate forming the upper surface 7a of the head base 7, thereby restricting the upward rotation of the first and second sheet holding members 20A, 20B.

[0035] When cleaning a floor surface with the floor wiper 1 having the above-described configuration, as shown in FIG. 2, the first and second sheet holding members 20A, 20B are held in the release position to expose the front portion FA and rear portion BA of the upper surface 6a of the buffer pad 6. Then, the first and second sheet holding members 20A, 20B are wrapped around the entire lower surface of the buffer pad 6 and both ends of the front portion FA and rear portion BA to cover them, and the first and second sheet holding members 20A, 20B are pressed downward. Then, the first and second sheet holding members 20A, 20B rotate downward about the first and second rotation axes L1, L2, and when the first and second sheet holding members 20A, 20B are held in the attached position, the first and second sheet holding members 20A, 20B and For buffering The sheet 4 is sandwiched between the head 3 and the pad 6. The head 3 is then moved back and forth or left and right while being pressed against the floor surface, thereby cleaning the floor surface.

[0036] When cleaning is completed and the sheet 4 is to be removed from the head 3, the tip portions 41, 41 of the first and second operating pieces 40A, 40B are pushed downward from the upper surface 7a side of the head base 7, and the first and second sheet holding members 20A, 20B are rotated so as to be lifted upward about the first and second rotation axes L1, L2. Then, when the first and second sheet holding members 20A, 20B are rotated to the release position, the sheet holding members 20A, 20B are held in the release position, and the clamped state of the sheet 4 is released, and the sheet 4 is removed.

[0037] Thus, with the flooring wiper 1, when removing the sheet 4 from the head 3 after cleaning, the first and second sheet holding members 20A, 20B can be rotated and displaced from the attached position to the released position by operating from the top surface 7a side of the head base 7, which does not contribute to holding the sheet 4, thereby preventing the fingertips from touching the dirty sheet 4.

[0038] In this embodiment, the buffer pad 6 and the head base 7 are fixed together by fitting the circular protrusion 8 of the head base 7 into the circular hole 6b of the buffer pad 6, but the buffer pad 6 and the head base 7 may also be attached together by an adhesive or other bonding means. Further, although only one spring member 30 is tensioned between the first and second sheet holding members 20A, 20B, a plurality of spring members may be tensioned at a plurality of positions between the first and second sheet holding members 20A, 20B. Alternatively, one end and the other end of the spring member 30 are attached to the first and second spring mounting portions 28, 29 of the first and second sheet holding members 20A, 20B, respectively. Alternatively, for example, two spring members may be used, with one end of the first spring member attached to the first spring mounting portion 28 of the first sheet holding member 20A and the other end attached to a predetermined position (e.g., the rear end) of the head base 7, and one end of the second spring member attached to the second spring mounting portion 29 of the second sheet holding member 20B and the other end attached to a predetermined position (e.g., the front end) of the head base 7.
