Technical Field

The utility model relates to a cleaning tool, which is equipped with a cleaning cloth for cleaning the dust on the surface to be cleaned.

Background

As is well known, cleaning tools are used for cleaning by attaching a cleaning sheet such as nonwoven fabric to the bottom surface of a head. Generally, locking portions are provided at four corners of the upper surface of the head portion to lock the cleaning sheet, and the floor surface is cleaned by the cleaning sheet covering the bottom surface of the head portion. For example, prior patent document 1 (publication No. kokai 2016-112743) discloses a cleaning tool in which sheet holding portions are provided at four corners of an upper surface of a head portion to which a cleaning sheet is locked.

However, when the cleaning sheet is removed from the sheet holding member composed of a plurality of elastic tongues on the upper surface of the head of the conventional cleaning tool, the cleaning sheet is easily caught between the elastic tongues and may be torn. Once the cleaning sheet is torn, there is a problem in that dust collecting ability is significantly reduced even if it is turned over and attached again to the holding member in order to use the surface which is not dirty.

In addition, since the sheet holding member of the conventional cleaning tool is an integrally molded product, there is a gap between the elastic tongues, so that the cleaning sheet has a weak holding force and cannot hold a thick cloth or the like.

In the present embodiment, for convenience of explanation, as shown in fig. 1, the longitudinal direction of the head 1 is referred to as the X direction, and the short direction is referred to as the Y direction.

The dimensions of the cleaning implement, for example, the head 1, which is substantially rectangular in shape, have a transverse length in the X direction of 30cm, a longitudinal width in the Y direction of 12cm, and a height of about 4 cm. For example, a cylindrical shank made of a light metal such as aluminum and a hard synthetic resin has a diameter of about 1.5cm and a length of about 120 cm. The cleaning implement may be of a suitable size depending on the cleaning site to be used.

The head 1 includes an upper surface plate 1a and a bottom surface plate 1b provided on the upper and lower surfaces, and the upper surface plate 1a and the bottom surface plate 1b are arranged in parallel at a predetermined interval via an intermediate portion 1 c. The intermediate portion 1c has an upper plate 1d to which the upper surface plate 1a is attached, a lower plate 1e to which the bottom surface plate 1b is attached, wall surfaces provided on side surfaces supporting the upper plate 1d and the lower plate 1e, and the like. Actually, the intermediate portion 1c is composed of a member divided into two in the vertical direction, and is formed integrally by adhesion, fitting, or the like. Even if the upper plate 1a and the upper plate 1d are not separated from each other, the bottom plate 1b and the lower plate 1e are not separated from each other, and the upper plate 1d has a surface of the upper plate 1a and the lower plate 1e has a surface of the bottom plate 1 b.

The upper surface plate 1a and the bottom surface plate 1b are rectangular plates for attaching a cleaning cloth on either surface, and a large number of concave and convex portions 1f are formed in a pattern on the surface. These concave-convex portions 1f can generate a large amount of unevenness on the surface of the attached cleaning sheet at the time of cleaning, and can effectively collect dust and the like at the concave portions.

In the center portions of the upper panel 1a, the bottom panel 1b, and the intermediate portion 1c, a notch portion 1h having a predetermined width is provided from the side of one long side 1g in the X direction to the center portion in the Y direction. The first rotating member 2 is pivotally connected to an intermediate portion 1c which is the tip of the cutout portion 1 h.

The upper plate 1d in the upper surface plate 1a and the lower plate 1e in the bottom surface plate 1b are provided with a plurality of pairs of tooth portions 1k at intervals along the

long sides

1g and 1i on both sides in the X direction, and the tooth portions 1k serve as locking portions of the cleaning cloth. The teeth 1k are provided in a gap 1j between an upper plate 1d and a lower plate 1e having

long sides

1g and 1i in the X direction of the

head

1, and 2 pairs of teeth 1k are provided along one

long side

1g and 1 i.

The pair of tooth portions 1k is composed of first trapezoidal teeth 1l projecting downward from the upper plate 1d and second trapezoidal teeth 1m projecting upward from the lower plate 1 e. The first trapezoidal tooth 1l and the second trapezoidal tooth 1m are flexible thin plates made of synthetic resin, which have a width of about 3 cm, a height of about 2cm, and a thickness of about 1 mm, and are trapezoidal in shape with a width decreasing toward the front end. The dimensions of the first trapezoidal teeth 1l and the second trapezoidal teeth 1m may be appropriately selected according to the size of the head 1 and the like.

The first trapezoidal teeth 1l facing the lower plate 1e and the second trapezoidal teeth 1m facing the upper plate 1d are set to a height not reaching the opposite side lower plate 1e and upper plate 1d, and are inclined inward as shown in fig. 5. Further, the first trapezoidal tooth 1l and the second trapezoidal tooth 1m contact each other at one contact point 1o between oblique sides of the trapezoids.

The first trapezoidal teeth 1l and the second trapezoidal teeth 1m may be attached to the upper plate 1d and the lower plate 1e as separate bodies, even if they are not integrally formed with the upper plate 1d and the lower plate 1 e.

The first rotary member 2 provided at the substantial center of the head portion 1 has a pair of first shaft portions 2a protruding in the X direction on both sides of the lower end, and the first rotary member 2 is pivotally connected to a bearing portion 1n provided in the intermediate portion 1c so as to be rotatable in the Y direction. The pair of second shaft portions 2b protrude in the Y direction on both sides of the upper portion of the first rotating member 2. A through hole 2c for inserting the bolt 5 is formed in the center of the pair of second shaft portions 2 b.

The second rotating member 3 has an arm portion 3a suspended in an inverted U shape from both sides, and a pair of bearing portions 3b are provided opposite to each other in the Y direction on the inner side surface of the arm portion 3 a. A through hole 3c communicating with the through hole 2c of the first rotary member 2 is formed in the center of the pair of bearings 3b, and a female screw to be screwed with the male screw of the bolt 5 is provided inside the through hole 3 c. The second rotating member 3 is rotatable in the X direction about the Y direction by receiving the pair of second shaft portions 2b on both sides of the first rotating member 2 in the pair of bearing portions 3b of the second rotating member 3.

In this way, after the first rotary member 2 and the second rotary member 3 are rotatably connected, the bolt 5 is inserted through the through hole 2c and the through hole 3c, and the internal thread of the through hole 3c and the external thread of the bolt 5 are threadedly mounted, thereby enhancing the connection between the first rotary member 2 and the second rotary member 3.

Due to the presence of the notched portion 1h, the shank portion 4 fixed to the upper end portion of the second rotary member 3 is rotationally moved from the upper surface plate 1a side to the opposite bottom surface plate 1b side by the first rotary member 2. That is, the handle 4 is rotatable 180 degrees in the Y direction with respect to the head 1 from a state in which the upper side shown in fig. 1 is the upper surface plate 1a to a state in which the upper side shown in fig. 3 is the lower surface plate 1 b. Further, the shank 4 can also be rotated in the X direction by rotation of the second rotation member 3 relative to the first rotation member 2. The handle 4 and the end of the second rotating member 3 may be connected by a snap or a thread, specifically, the lower end of the handle 4 and the end of the second rotating member 3 are provided with matching snaps for snap connection, or the lower end of the handle 4 is provided with an external thread, and the end of the second rotating member 3 is internally provided with an internal thread screwed with the external thread, so that the handle 4 and the end of the second rotating member 3 are connected by a thread.

As shown in FIG. 6, in order to use the cleaning tool, for example, a commercially available cleaning sheet S made of a nonwoven fabric having a width of about 30cm, a length of 20cm and a thickness of about 0.5mm is provided on the bottom panel 1b side of the head 1. Then, the edge portion of the cleaning sheet S is pushed into the tooth portion 1k along the long sides 1g of both sides of the head 1 with fingers and locked. So that the cleaning sheet S can be stably clamped and locked between the four pairs of first trapezoidal teeth 1l and second trapezoidal teeth 1m in total. In the present embodiment, the cleaning sheet S is used as the cleaning cloth, but a cleaning cloth thicker than the cleaning sheet S may be used.

When the cleaning sheet S is locked to the tooth portions 1k, the first trapezoidal teeth 1l and the second trapezoidal teeth 1m made of a flexible thin plate contact each other at the contact point 1o between the oblique sides of the trapezoids. The cleaning sheet S is clamped in a moderately twisted state, and the cleaning sheet S is not easily peeled off during use.

Then, the floor or the like is cleaned by wiping the floor with the cleaning sheet S on the bottom panel 1b side by the handle portion 4. When the surface of the cleaning sheet S becomes dirty due to use, only the edge portion on the one side of the cleaning sheet S is removed from the tooth portion 1k on the long side 1g side of the head portion 1 on the side where the notch portion 1h exists. In this case, the cleaning sheet S can be removed by lightly pulling the cleaning sheet S horizontally from the first and second trapezoidal teeth 1l and 1m, applying pressure to the cleaning sheet S without applying pressure to the first and second trapezoidal teeth 1l and 1 m.

The cleaning tool may mount the front and back surfaces of the cleaning sheet S with respect to the respective upper and

lower surface panels

1a and 1 b. When the cleaning sheet S covering the bottom panel 1b shown in fig. 6 becomes dirty, the edge on the long side 1i side remains locked to the tooth 1k, and the edge portion of the cleaning sheet S is removed from the tooth 1k on the long side 1g side of the notched portion 1h of the head 1.

As shown in fig. 4, the 1 st rotating member 2 is rotated 180 degrees with respect to the head 1, the handle 4 is rotated upward in the Y direction using the notch portion 1h, the head 1 is turned upside down, the tooth portions 1k of the edge portion on the long side 1i are caught on the edge portion of the cleaning sheet S, the upper surface plate 1a is covered with the dirty surface, and the locking is performed with the tooth portions 1k on the long side 1 g.

In this way, the dirty cleaning sheet S turned over on the bottom panel 1b, the surface not exposed to the upper surface panel 1a side by the dirty is removed, and the handle 4 having been rotated to the bottom panel 1b side of the opposite side is removed. Then, cleaning can be performed with the cleaning sheet S covering the upper surface plate 1a facing downward.

And after the front and back surfaces of the cleaning sheet S are sufficiently used, the cleaning sheet S is taken out from the four pairs of tooth portions 1k of the head 1 and replaced with a new cleaning sheet S.

Therefore, compared with the conventional art in which the cleaning sheet S is temporarily removed and reversed again, the cleaning sheet S can be reversed with one edge locked. Further, the area where the hand touches the cleaning sheet S is reduced, and the hand does not become dirty.

Further, instead of the holder constituted by the plurality of elastic tongues at the four corners of the head top surface of the conventional cleaning implement, a recess is provided at the four corners of the head top surface, a tooth portion 1k constituted by the first trapezoidal tooth 1l and the second trapezoidal tooth 1m is provided at the opening of the recess, and the tooth portion 1k may be used for a holding mechanism of the cleaning cloth of the cleaning implement.

According to the utility model discloses a cleaning tool, through with first trapezoidal tooth 1l and the locking part that the trapezoidal tooth 1m of second that set up on head 1 was used as cleaning cloth, can lock the cleaning sheet S and the rag of different thickness to can install and remove easily.

Further, the tooth portion 1k composed of the first trapezoidal tooth 1l and the second trapezoidal tooth 1m which contact each other at one contact point between the oblique sides of the trapezoids has an appropriate gripping force, the cleaning cloth is not easily detached from the engaged portion during cleaning, and when the cleaning cloth is removed, it is hardly caught and can be easily removed.

In addition, compared with the existing cleaning tool in which the holding member is an integrally molded product, since the first trapezoidal tooth 1l and the second trapezoidal tooth 1m are not integrally molded but separately molded, the first trapezoidal tooth 1l and the second trapezoidal tooth 1m can be provided without generating a gap. Therefore, the clamping force to the cleaning cloth can be enhanced as compared with the existing cleaning tool.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
