Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a mop, and more particularly to a mop capable of replacing a wiping sheet.

[Prior Art] Various mops have been proposed in which a wiping sheet is replaceably attached. However, this type of conventional mop generally has a drawback that the replacement work of the wiping sheet is troublesome, the mounting strength is small, and the wiping sheet is likely to fall off when a large frictional force acts on the wiping sheet during cleaning. Moreover, there are various types of wiping sheets for dry wiping, water wiping, etc., and their thicknesses are also different.However, conventional mops have limited wiping sheets that can be used, and wiping sheets of different thicknesses can be used. It was difficult to use the sheet in the same way.

[Problems to be Solved by the Invention] An object of the present invention is to configure a mop in which a wiping sheet can be replaced so that even wiping sheets having different thicknesses can be easily and firmly attached. .

[Means for Solving the Problems] In order to solve the above problems, according to the present invention, a cushioning member is attached to a lower surface, and a compressive elastic member and a wiper sheet locking protrusion are provided at both widthwise end portions of an upper surface. A lower plate provided with and a upper plate to which a grip handle is attached, and these two plates are formed into a rectangular shape having substantially the same shape, and are openably and closably connected by a hinge that is sufficiently shorter than the plate width at one end in the length direction. At the same time, the other end can be engaged and disengaged by the locking means, and the wiping sheet wound between the upper plate and the lower plate can be held with the end of the wiping sheet wound around the lower plate being locked to the protrusion. , Is characterized by being fixed.

[Operation] When the wiping sheet is attached, the wiping sheet is wound from the bottom surface of the lower plate to the side of the lower plate and the projecting portion of the upper surface so as to cover the elastic member when the wiping sheet is attached, and both ends of the sheet are projected. Then, the upper plate is closed and locked to the lower plate. As a result, the front and rear ends of the wiping sheet are sandwiched and fixed between the upper plate and the lower plate via the elastic members while being retained by the protrusions.

Therefore, not only can the wiping sheet be firmly fixed by the protrusion and the elastic member, but even if the wiping sheets have different thicknesses, the difference in the thickness can be absorbed by the compression deformation of the elastic member. By this, it is possible to securely fix.

When replacing the wiping sheet, when removing it from the lower plate, it is only necessary to open the upper plate.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings.

The mop shown in FIGS. 1 to 5 is a lower plate 2 for winding a wiping sheet 1 made of a water-absorbent flexible material such as non-woven fabric, woven fabric or paper, and an upper plate 3 to which a grip handle 11 is attached. It has and.

The lower plate 2 is formed of a synthetic resin, metal, wood or the like into a substantially rectangular shape, and a cushioning member 4 made of an elastic material such as sponge or synthetic resin foam is integrally formed from the bottom surface to the side surfaces. Is glued to. Further, compressible elastic members 5, 5 such as sponge for elastically supporting the end of the wiping sheet 1 with the upper plate 3 are provided at both ends in the width direction on the upper surface of the lower plate 2. Inside the elastic member 5, there are provided a plurality of protrusions 6 at which the ends of the wiping sheet 1 are locked. This protrusion 6 may be formed integrally with the lower plate 2 or may be a small portion of the hook-and-loop protrusion side of the surface fastener fixed. Further, the protrusions 6 can be provided so as to be located at the inner four corners of the elastic members 5, 5 as shown in the figure.

On the other hand, the upper plate 3 has a rectangular shape that is substantially the same as the lower plate 2 and is made of synthetic resin, metal, wood or the like as the lower plate 2. As can be seen from FIG. 1, FIG. 2, and FIG. 4, the hinge 8 rotatably supports the lower plate 2 at one end in the longitudinal direction thereof, and is shown by a solid line in FIG. The wiping sheet 1 is configured to be rotatable between a fixed position and an opening position of the wiping sheet 1 shown by a chain line. As this hinge 8, one having a width sufficiently shorter than the plate width of the lower plate 2 and the upper plate 3 is used, and it is provided almost at the center of these plate widths.
Both ends of the wiping sheet 1 can be projected laterally in the length direction of the upper plate 3 and the lower plate 2 in a state of being wound around (see FIGS. 4 and 5).

Further, locking means 9 for fixing the upper plate 3 and the lower plate 2 to each other is provided at the ends of the upper plate 3 and the lower plate 2 opposite to the mounting positions of the hinges 8. There is. As shown in FIG. 4, the locking means 9 has a locking bullet piece 9a protruding from the lower plate 2 and a locking bullet piece 9a formed on the upper plate 3 for locking. It comprises a locking hole 9c having a tongue 9b, and when the upper plate 3 is rotated to the fixed position, the locking bullet 9a is automatically fitted into the locking hole 9c to engage with the locking edge 9b. On the other hand, when the upper plate 3 is stopped and rotated to the open position, the locking bullet piece 9a may be biased with a finger to be removed from the locking edge 9b.

Further, as shown in FIGS. 3 and 4, the grip handle 11 is attached to the upper surface of the upper plate 3 so as to be tiltable in two directions, ie, front and rear and left and right. That is, the first mounting member 12 is pivotally supported on the upper surface of the upper plate 3 so as to be rotatable in the front-rear direction,
A second mounting member 13 is pivotally supported on the first mounting member 12 so as to be rotatable in the left-right direction, and the grip handle 11 is attached to the second mounting member 13.
Is attached.

When attaching the wiping sheet 1,
With the upper plate 2 rotated to the open position, as shown in FIGS.
As shown in the drawing, the wiping sheet 1 is wound from the bottom surface of the lower plate 2 to the side surface and the upper surface portion where the protrusion 6 is formed so as to enclose the cushioning member 4, and both ends of the sheet 1 are attached to the protrusion 6. After being stopped and temporarily fixed, the upper plate 3 is rotated to the fixed position, and the locking bullet piece 9a of the locking means 9 is locked to the locking edge 9b. Then, as shown in FIGS. 3 to 5, the front and rear end portions of the wiping sheet 1 are held between the upper plate 3 and the lower plate 2 via the elastic members 5 while being retained by the protrusions 6. , Fixed.

In this case, the wiping sheet 1 has the protrusions 6 at both ends thereof.
As long as the upper plate 3 and the lower plate 2 are formed to have substantially the same size,
The width of the portion of the wiping sheet held between the upper plate 3 and the lower plate 2 can be minimized. Further, even if the wiping sheet 1 to be used has different thicknesses, the difference in the thickness is absorbed by the compressive deformation of the elastic member 5, so that the wiping sheet 1 having various thicknesses can be reliably fixed. . Further, not only the end of the wiping sheet 1 is elastically held by the elastic member but also the end is locked to the protrusion 6, so that a large frictional force is exerted on the wiping sheet 1 when the mop is used. Even if it works, the sheet does not fall off. Furthermore, since the hinges 8 having a length sufficiently shorter than the widths of the upper and lower plates 2 and 3 are used, both ends of the wiping sheet 1 are projected laterally in the length direction of the upper plate 3 and the lower plate 2. Therefore, the cleaning can be efficiently performed.

On the other hand, when replacing the wiping sheet 1, use the lower plate 2
When removing the wiping sheet 1 from the lower plate 2, the locking bullet 9a of the locking means 9 is removed from the locking edge 9b and the upper plate 3 is rotated to the open position. can do.

Although not particularly described in the description of the above embodiment,
It is also possible to provide a means for ensuring the gripping of the wiping sheet, which is composed of the same compressible elastic member or protrusions, at a position corresponding to the compressible elastic members 5, 5 on the lower surface of the upper plate 3.

[Effects of the Invention] As described above, according to the present invention, a compressible elastic member and a wiper sheet locking protrusion are provided at both widthwise end portions of the upper surface of the lower plate, and the wiper sheet wound around the lower plate is provided. Since the wiping sheet is elastically sandwiched and fixed between the upper plate and the lower plate via the elastic member in a state where the end portion is locked to the protrusion,
The wiping sheet can be very firmly fixed, and even if a large frictional force acts on the wiping sheet when the mop is used, the sheet does not fall off. Moreover, even with respect to the wiping sheets having different thicknesses, the difference in the thickness can be absorbed by the compressive deformation of the elastic member, so that the wiping sheets with various thicknesses can be reliably fixed.

Moreover, since the upper plate and the lower plate are formed to have substantially the same size, the wiping sheet is held between the upper plate and the lower plate in combination with the formation of the protrusion and the elastic member. The width of the part to be cut can be suppressed to the necessary minimum, and the economical efficiency of the mop can be improved. Moreover, since the hinges having a length sufficiently shorter than the width of the upper and lower plates are used, both ends of the wiping sheet can be projected laterally in the length direction of the upper plate and the lower plate when the wiping sheet is attached, Thereby, cleaning can be performed efficiently.
