Description

  The present invention relates to a flooring wiper that performs cleaning by mounting a cleaning sheet on a wiper head.

  For example, like a mop disclosed in Patent Document 1 or Patent Document 2, a flooring wiper that cleans a floor of a board by mounting a cleaning sheet on a head is known. In such a flooring wiper, various fixing mechanisms are used to fix the seat mounted on the head in a mounted state.

The mop disclosed in Patent Document 1 forms a plurality of elastic tongue pieces by providing a plurality of intersecting cuts on the upper surface of a head (support plate), and an end of a sheet attached to the head is formed on the cuts. The elastic tongue piece is locked by being pushed in, and thereby the sheet is fixed in the mounted state.
Since the fixing mechanism using such a cut can be fixed simply by pushing the sheet into the cut, the sheet mounting operation is simple. Further, even when a sheet that has been soiled by cleaning is removed from the head, it is only necessary to pull the sheet slightly hard and pull it out from the cut, so that the removal work is also easy.

  However, the sheet fixing mechanism disclosed in Patent Document 1 is suitable when a thin sheet of about 1 mm is used, but is not suitable when using a thick sheet as low as 2-5 mm. is there. The reason is that in the case of the thin sheet, it can be easily pushed into the cut and is easily locked to the elastic tongue, but the thick sheet is bulky and difficult to push into the cut. Not only that, even if it is pushed in, it is difficult to be engaged with the elastic tongue piece, so that it is easily detached from the head.

  On the other hand, the mop disclosed in Patent Document 2 forms a fastening hole on the top surface of the head (mounting base) and fits the fastening hole attached to the flexible fastening member attached to the top surface of the head. A protrusion is formed, and a locking hole is formed in the sheet. When the sheet is attached to the head and fixed, the end of the fixing member is lifted upward, and the fixing member and the head The sheet is fixed by sandwiching the end of the sheet between them and inserting the protrusion into the fixing hole of the head through the locking hole of the sheet.

  The mop disclosed in Patent Document 2 is excellent in that both a thin sheet and a thick sheet can be used, but when using any sheet, the sheet is fixed or removed. In this case, the both ends of the fixing member are lifted and deformed in the direction away from the head, and at the same time, the protrusion must be fitted into or escape from the locking hole of the sheet. Compared with the one that uses a cut such as the flooring wiper disclosed in Document 1, the operation is somewhat troublesome.

  The technical problem of the present invention is to provide a rational and easy-to-use flooring wiper that can selectively use both a thin sheet and a thick sheet by properly using two types of sheet fixing portions having different configurations. There is to do.

  In order to solve the above problems, a flooring wiper of the present invention has a handle and a wiper head attached to the tip of the handle in a tiltable manner, and the wiper head has a rectangular shape having a longitudinal direction and a transverse direction. A base plate and sheet fixing members attached to one end side and the other end side in the longitudinal direction of the upper surface of the base plate, respectively, and the base plate is paired with one end side and the other end side in the longitudinal direction of the base plate. A pair of sheet sandwiching portions, the pair of sheet sandwiching portions formed at opposite positions of one end side and the other end side in the short direction of the base, and leg portions rising from the base; A flange portion extending from the upper end of the leg portion toward the inside of the base, and the sheet fixing member has flexibility, and the free ends at both ends in the longitudinal direction are provided between the pair of sheet sandwiching portions. The pair of sheets in a posture facing the buttocks A plurality of elastically deformable locking pieces defined by a plurality of slits are formed on one end side and the other end side in the longitudinal direction of the sheet fixing member. The first sheet fixing portion that locks the thin sheet and fixes the seat in a mounted state is formed by the locking piece formed on the free end of the sheet fixing member and the base. A second sheet fixing portion that clamps a thick sheet and fixes the sheet in a mounted state is formed by the sheet clamping portion.

In the present invention, the sheet fixing member has a wide portion formed at both ends in the longitudinal direction, and a narrow portion interposed between the wide portions at both ends, and the lateral width of the wide portion is the narrow portion. The wide portions are formed to be larger than the width of the wide portion, and extending portions projecting laterally from the narrow portion are formed at one end and the other end of the wide portion in the width direction.
The width of the wide portion is preferably larger than the length of the flange portion in the sheet clamping portion along the longitudinal direction of the base.

Preferably, in the present invention, the region where the locking piece of the sheet fixing member is formed is thinner than the region other than the region by forming a recess on the back surface of the sheet fixing member. In addition, the sheet fixing member is curved so that the height gradually decreases from the central portion in the longitudinal direction toward the free ends at both ends in the longitudinal direction.
Further, in the present invention, end walls rising from the base are formed at both ends in the short direction of the upper surface of the base over the entire length in the longitudinal direction of the base. By extending the collar portion, the end wall may also serve as the leg portion of the sheet clamping portion.

  According to the present invention, the first sheet fixing portion configured by the locking piece formed on the sheet fixing member, and the free end of the sheet fixing member and the flange portion of the sheet clamping portion formed on the base. By selectively using the second sheet fixing portion, both a thin sheet and a thick sheet can be selectively used. The first sheet fixing part is formed on the sheet fixing member, and the second sheet fixing part is formed by combining a part of the sheet fixing member and a part of the base. The configuration is very reasonable and easy to use.

The flooring wiper 1 includes a wiper head 2 having a horizontally long rectangular shape in plan view, and a central position on the upper surface of the wiper head 2. The wiper head 2 includes a thin cleaning sheet 4a (see FIG. 8) having a thickness of about 1 mm and a thick sheet having a thickness of about 2 to 5 mm. The cleaning sheet 4b (see FIG. 9) is selectively mounted and used.
The sheets 4a and 4b are rectangular sheets formed of a nonwoven fabric or a woven fabric. In the following description, when it is not necessary to distinguish between the thin sheet 4a and the thick sheet 4b, only “sheet 4” is displayed.

The handle 3 is connected to the wiper head 2 via a universal joint 6 so that the handle 3 can tilt at any angle in any direction.
The universal joint 6 is rotatable about a first axis L1 extending in the longitudinal direction (left-right direction) of the wiper head 2 to a pair of left and right bearings 7a, 7b formed on the upper surface of the wiper head 2. A supported first joint member 6a, and a second joint member 6b rotatably connected to the first joint member 6a about a second axis L2 orthogonal to the first axis L1; The second joint member 6b is fixedly connected to the tip of the handle 3.
The handle 3 may be formed to be stretchable for length adjustment.

  The wiper head 2 includes a base 8 having a horizontally long rectangular shape in plan view, a cushioning pad plate 9 attached to the lower surface of the base 8, and one end side and the other end side of the base 8 in the longitudinal direction. The sheet fixing member 10 is attached to each of the upper surfaces.

  The base 8 is integrally molded of a synthetic resin, and on the upper surface thereof, the hollow bearing portions 7a and 7b are formed at the center position in the short direction (front-rear direction) of the base 8, An end wall 11 is formed so as to extend in the left-right direction of the base 8 along the first axis L <b> 1. Is formed over the entire length of the base 8 in the longitudinal direction (left-right direction). The thick sheet 4b is formed in cooperation with the sheet fixing member 10 on one end side and the other end side of the base 8 in the left-right direction. A pair of sheet holding portions 12 for holding the sheet is formed, and a base side attachment portion 13 for attaching the sheet fixing member 10 to the base 8 is formed between the pair of sheet holding portions 12, 12. Yes.

  The pair of sheet clamping portions 12 and 12 are formed at opposite positions on one end side and the other end side in the width direction of the base 8, and a leg portion 12 b rising from the base 8 and the leg portion 12 b. And an eaves part 12a extending toward the inside of the base 8. In the illustrated embodiment, since the flange portion 12a extends from the upper end portion of the end wall 11, a part of the end wall 11 also serves as the leg portion 12b. However, the leg portion 12b may be formed separately from the end wall 11.

The base-side mounting portion 13 includes a pair of parallel partition walls 15, 15 extending in the front-rear direction of the base 8, and a pair of locking projections 16 formed between the pair of partition walls 15, 15. 16 are formed. The pair of partition walls 15, 15 are formed at opposite positions in the left-right direction of the base 8, and the pair of locking projections 16, 16 are also formed at opposite positions in the left-right direction of the base 8, At the upper ends of the pair of locking projections 16, hooks 16 a that face in opposite directions are formed.
The length of the partition wall 15 is preferably １ ／ or less, for example, about ¼ of the width in the front-rear direction of the base 8, and the length of the locking projection 16 is It is even shorter than the length and is about 1/3 of the length of the partition wall 15.

  The pad plate 9 is for enhancing cushioning when the sheet 4 is cleaned, and a synthetic rubber plate, a sponge plate formed by foaming a synthetic resin, a cloth made of a nonwoven fabric or a woven fabric is laminated. The formed fiberboard or the like is formed to a thickness of about 3 to 10 mm, and is fixed to the lower surface of the base 8 by a method such as locking with a hook or bonding with an adhesive or a double-sided adhesive tape. The pad plate 9 is formed slightly larger than the base 8 so that it slightly protrudes in the left-right direction and the short direction of the base 8.

5 to 7, the sheet fixing member 10 is a flexible band-shaped member made of synthetic rubber, synthetic resin, or the like, and has a longitudinal direction and a short direction (lateral width direction). A wide portion 10a is formed at one end and the other end in the longitudinal direction, a narrow portion 10b is formed between the two wide portions 10a, 10a, and the base is formed on the lower surface of the narrow portion 10b. A fixing member-side mounting portion 17 for mounting to the eight base-side mounting portions 13 is formed.
Further, the sheet fixing member 10 is gently curved in a convex shape upward so that the height gradually decreases from the central portion in the longitudinal direction toward the free ends 10c and 10c at both ends in the longitudinal direction. ing.

  The widths Wa of the two wide portions 10a are equal to each other and are larger than the width Wb of the narrow portion 10b. For this reason, one end and the other end of the wide width portion 10a in the lateral width Wa direction protrude laterally from one end and the other end of the narrow width portion 10b in the lateral width Wb direction, and thereby the lateral width of the wide width portion 10a. Extending portions 10d for hooking fingers are formed at one end and the other end in the Wa direction, respectively.

In addition, a plurality of elastically deformable members defined by a plurality of cuts 19 are provided on one end side and the other end side in the longitudinal direction of the sheet fixing member 10 in a region straddling the wide width portion 10a and the narrow width portion 10b. Stop pieces 18 are respectively formed, and the locking pieces 18 form first sheet fixing portions 20 for locking the thin sheet 4a and fixing the sheet 4a in the mounted state.
The front end of the locking piece 18 is sharp and can be locked to the sheet 4a. Further, the sharp tip portion of the locking piece 18 is made difficult to be deformed by forming a thick portion 18a having a thickness slightly thicker than other portions, and thereby the locking piece 18 is locked to the sheet 4a. Power is increased.

  The sheet fixing member 10 is disposed between the pair of sheet sandwiching portions 12 and 12 of the base 8 in a posture in which the longitudinal direction is directed in the front-rear direction of the base 8, and the fixing member side mounting portion 17 It is attached to the base side mounting portion 13 of the base 8 as follows.

  That is, the fixing member-side mounting portion 17 has a rectangular frame shape, and of the four frame walls, the inner surfaces of the lower end portions of the pair of frame walls 17a and 17a facing the pair of locking projections 16 and 16 In addition, a hook 17b is formed to be engaged with the hook 16a of the locking projections 16,16. Then, the hook 17b of the fixing member side mounting portion 17 and the hook 16b of the locking projections 16 and 16 are locked to each other, whereby the sheet fixing member 10 and the narrow width portion 10b are the pair of partition walls. 15 and 15 is attached to the upper surface of the base 8 with a posture interposed therebetween.

  Both end portions in the longitudinal direction of the sheet fixing member 10 are freely displaceable free ends 10c, and the free ends 10c are opposed to the front end portions of the flange portions 12a of the sheet clamping portion 12, and the flange portions 12a The free end 10c forms a second sheet fixing portion 21 for sandwiching the thick sheet 4b and fixing the sheet 4b in the mounted state.

  In the illustrated example, the free end 10c slightly overlaps with the flange portion 12a, and abuts the lower surface of the flange portion 12a by sinking under the flange portion 12a, as shown in FIG. In addition, when the thin sheet 4a is used, the free end 10c can be lifted on the flange 12a so that the sheet 4a can be easily locked to the locking piece 18.

Alternatively, the free end 10c of the sheet fixing member 10 occupies the same height as the flange portion 12a and abuts against the flange portion 12a, or a slight gap is maintained between the sheet fixing member 10 and the flange portion 12a. It can also be formed so as to face the flange 12a in a state.
Further, the lateral width Wa of the wide width portion 10 a is formed larger than the length X of the flange portion 12 a in the sheet clamping portion 12 along the longitudinal direction of the base 8.

The region of the sheet fixing member 10 where the locking piece 18 is formed is thinner than the region other than the region by forming a recess 23 on the back surface of the sheet fixing member 10. With this configuration, the elastic force of the sheet fixing member 10 in the region is reduced and the elastic force of the other portions is prevented from being reduced, whereby the thin sheet 4 a is engaged with the locking piece 18. It is possible to facilitate the elastic deformation of the locking piece 18 at the time of stopping, and at the same time, to secure a sufficient holding force when the thick sheet 4b is held between the free end 10c and the flange portion 12a. I have to.
The locking piece 18 is not necessarily formed so as to straddle the wide portion 10a and the narrow portion 10b, and can be formed only in the wide portion 10a. In this case, the concave portion 23 is also formed only in the wide width portion 10a.

  In the case of cleaning using the thin sheet 4a in the flooring wiper 1 having the above configuration, as shown in FIG. 8, the free end 10c of the sheet fixing member 10 is brought into contact with the flange 12a from above. In this state, the end of the sheet 4a wound around the wiper head 2 is pushed into the cut 19 from above the sheet fixing member 10, thereby elastically deforming the locking piece 18 and a plurality of engagements. The sheet 4 a is fixed to the wiper head 2 by being inserted between the stopper pieces 18 and elastically locked to the stopper pieces 18.

  After removing the soiled sheet 4a from the wiper head 2 after cleaning the floor surface or the like in this state, the end of the sheet 4a is strongly pulled upward above the wiper head 2, and the locking piece 18 is The sheet 4a can be detached from the wiper head 2 by elastically deforming the sheet 4a in the pulling direction to release the lock on the sheet 4.

  Further, in the case of cleaning using the thick sheet 4b, as shown in FIG. 9, the free end 10c of the sheet fixing member 10 is placed under the flange 12a, and the wiper head 2 The end portion of the sheet 4b wound around is inserted between the free end 10c and the flange portion 12a of the sheet holding portion 12 by elastically deforming the free end 10c downward, and the free end 10c and the flange portion The sheet 4b is held in the wiper head 2 in a fixed state by being sandwiched by 12a.

When removing the sheet 4b soiled by cleaning from the wiper head 2, the free end 10c of the sheet fixing member 10 is elastically deformed downward by pushing down the extending portion 10d of the sheet fixing member 10 with a finger. The sheet 4b can be detached from the wiper head 2 by releasing the nipping of the sheet 4b by the free end 10c and the flange 12a and pulling out the sheet 4b to the outside in that state.
At this time, the lateral width Wa of the wide width portion 10a of the sheet fixing member 10 is formed larger than the length X of the flange portion 12a, and the extending portion 10d extends laterally from the flange portion 12a. Therefore, the operation of pushing down the extending portion 10d can be easily performed.

In this way, the flooring wiper 1 is attached to the first sheet fixing portion 20 constituted by the locking pieces 18 formed on the sheet fixing member 10, and the free end 10 c of the sheet fixing member 10 and the base 8. By using the second sheet fixing portion 21 formed by the formed flange portion 12a of the sheet clamping portion 12 depending on the thickness of the sheet 4 to be used, both the thin sheet 4a and the thick sheet 4b can be used. Can be used selectively.
The first sheet fixing part 20 is formed on the sheet fixing member 10, and the second sheet fixing part 21 is formed by combining a part of the sheet fixing member 10 and a part of the base 8. Therefore, its configuration is very rational and easy to use.
