Description

  The present invention relates to a flooring wiper that performs cleaning by mounting a cleaning sheet on a wiper head, and more particularly to a flooring wiper that can be used on both sides by turning the sheet upside down. It is.

  A flooring wiper for cleaning a floor surface or the like by mounting a cleaning sheet on a wiper head has been well known. This kind of flooring wiper normally uses both the front and back sides of the sheet efficiently, so if one side gets dirty, it is turned over to use the other side. Since the whole was once removed from the wiper head, turned over, and then attached to the wiper head again, there was a problem that hands were easily soiled by dust adhering to the sheet.

  On the other hand, Patent Document 1 and Patent Document 2 disclose a mop in which the entire wiping cloth (wiping cloth) can be reversed without removing it from the head.

Among these, the mop disclosed in Patent Document 1 forms a head by overlapping two mounting members so that they can be opened and closed, and the head is attached to the tip of a handle so that it can be turned upside down. By sandwiching both ends of the wiping cloth mounted on one side between the two mounting members, the wiping cloth is fixed in the mounting state.
And when reversing the front and back of the wiping cloth soiled by cleaning, remove the other end of the wiping cloth from the head while holding one end of the wiping cloth between the two mounting members, The upper and lower surfaces of the wiping cloth are turned upside down, and the other end of the wiping cloth is sandwiched between the two mounting members again.

  In addition, the mop disclosed in Patent Document 2 is formed so that a part of the head can be freely opened and closed to sandwich one end of the wiping cloth, and the other end of the wiping cloth is formed on both upper and lower surfaces of the head. When the wiping cloth is turned upside down, it is reversed with one end sandwiched by the head as a fulcrum, and the other end is locked to the non-slip portion. I will let you.

The mops disclosed in Patent Document 1 and Patent Document 2 have the advantage that the entire wiping cloth can be reversed without being completely removed from the head, but the head is formed to be openable and closable. Therefore, the structure of the head is complicated accordingly, and there is a slight difficulty in that the opening / closing operation of the head is required when the wiping cloth is reversed.
In addition, since the end of the wiping cloth is directly sandwiched between the upper and lower mounting members forming the head, it is suitable when using a wiping cloth having a large thickness (for example, 5 mm or more) such as a dust cloth. However, when a sheet having a small thickness (for example, about 1 mm) is used, it is not suitable because the sheet easily slips off.

It is formed to extend to one side surface of the head 3. Hereinafter, the configuration of the wiper head 3 will be described in more detail. In the following description, of the front and rear side surfaces 7a and 7b of the wiper head 3, the side surface on which the escape hole 11 is formed is referred to as a first side surface 7a, and the opposite side surface is referred to as a second side surface 7b. Shall be called.

  As is clear from FIGS. 3 and 4, the wiper head 3 is attached to the base 14 formed by joining two board members 14 a and 14 a to each other, and both the upper and lower surfaces of the base 14. The pad plate 15 for buffering and a plurality of locking blocks 16 forming the sheet locking portion 8 are provided, and the surface of the pad plate 15 is the mounting surfaces 6a and 6b. In the illustrated embodiment, a total of four locking blocks 16 are provided.

  The two board members 14a and 14a are shallow dish-shaped members molded of hard synthetic resin, have the same shape, and one of the front and rear side surfaces 7a and 7b of each board member 14a. The side surface (first side surface) 7a is formed with the escape hole 11 and two block mounting portions 17 having a concave shape in plan view where the locking block 16 is fitted, and the other side surface ( On the second side surface 7b, two concave block mounting portions 17 into which the locking blocks 16 are fitted are formed. The two block mounting portions 17 formed on the first side surface 7a and the two block mounting portions 17 formed on the second side surface 7b are the center in the longitudinal direction of the board member 14a (and hence the wiper head 3). Are arranged so as to be symmetric with respect to the center in the lateral direction.

  The left and right side ends of the block mounting portion 17 are provided with recesses 19 in which the vertical portions 18a of the fixing projections 18 formed on the left and right side surfaces of the locking block 16 are fitted and locked. It is formed so as to open to the joint surface side of 14a.

  In addition, a plurality (three in the figure) of connecting protrusions 22 are formed on one side of the longitudinal direction on the joint surface of the board member 14a, and a plurality of connecting holes are formed on the other half of the longitudinal direction. A portion 23 is formed, and the number of the connecting projections 22 and the number of the connecting hole portions 23 are the same as each other, and are arranged so as to be symmetric with respect to the center in the longitudinal direction of the panel member 14a.

  Then, the joint surfaces of the two board members 14a and 14a are butted against each other, and the connection protrusion 22 of one board member 14a is press-fitted into the connection hole 23 of the other board member 14a, thereby The board | substrates 14a and 14a are mutually joined and the said base | substrate 14 is assembled. At this time, by disposing the locking block 16 in the block mounting portion 17, the vertical portions 18a of the fixing projections 18 on both side surfaces of the locking block 16 are formed on the two board members 14a and 14a. The locking block 16 is fixed in the block mounting portion 17 by being fitted and locked in the recess 19, and this will be more apparent in the description of the locking block 16 described later. It will be.

  An outer surface of the board member 14a, that is, a surface opposite to the joint surface is an attachment surface for attaching the pad plate 15. The attachment surface includes a periphery of the escape hole 11 and the block attachment portion 17. A wall 24 having a height approximately equal to or less than the thickness of the pad plate 15 is formed around the periphery of the pad plate 15, and the other portions are flat.

  The pad plate 15 is for enhancing cushioning when the floor surface is cleaned with the sheet 4, and a synthetic rubber plate, a sponge plate formed by foaming a synthetic resin, a cloth made of a nonwoven fabric, a woven fabric or the like is used. It is formed to a thickness of about 5 to 10 mm by a laminated fiberboard or the like, and is fixed to the outer surface of the two board members 14a, 14a, that is, the upper and lower surfaces of the base plate 14 with an adhesive or a double-sided adhesive tape. ing. The pad plate 15 has a relief hole 15a corresponding to the relief hole 11 of the base 14 and a notch 15b corresponding to the block mounting portion 17, and is formed in the same planar view shape as the base 14. The base 14 is slightly larger than the base 14 so that it slightly protrudes in the longitudinal direction and the short direction.

The locking block 16 is formed of a synthetic resin that is softer than the board member 14a or a synthetic rubber, and as is apparent from FIGS. 5 and 6, a hollow body 26 having a rectangular frame shape. And a front end wall 27 that closes the front end surface of the body 26, and the cut 9 and the locking piece 10 are formed in the front end wall 27.
The height of the body 26 is equal to or higher than the height of the base 14, but is lower than the overall height of the wiper head 3 including the pad plate 15.
Further, the thickness T1 of the body 26 is formed to be thicker than the thickness T2 of the front end wall 27 (for example, T1 = 1.5 mm, T2 = 1 mm), and a part of the sheet is pushed into the cut 9. Thus, when the locking piece 10 is deformed inward, the body 26 is not deformed following the depression.

  The fixing projections 18 are formed on the left and right side surfaces of the body 26. The fixing protrusion 18 has a T-shaped cross section, and includes a horizontal portion 18b extending horizontally from the side surface of the body 26 and the vertical portion 18a extending vertically from the tip of the horizontal portion 18b. The horizontal portion 18b is sandwiched between the edges of the depressions 19 for locking the upper and lower board members 14a and 14a, and the upper and lower parts of the vertical portion 18a are the above-mentioned of the upper and lower board members 14a and 14a. By fitting and locking in the recess 19, the locking block 16 is positioned in the block mounting portion 17 and the front end wall 27 forms a part of the side surface of the wiper head 3. It is fixed.

  Accordingly, the locking block 16 can be fixed to the base 14 without using a method such as adhesion or screwing. When the locking block 16 is damaged, it can be replaced with a new locking block 16 by separating the two board members 14a, 14a that are joined.
