Description

  The present invention is a cleaning mop for removing dust and dirt on the floor, and in particular, the mop body attached to the tip of the handle handle is an obstacle so that the chair, desk leg and the like can be easily cleaned. It is related with the mop for cleaning devised so that it may automatically turn and clean when it comes into contact.

  Mops such as dust mops and dust cloth type mops are often used for cleaning work such as wiping and sweeping large floors. These mops have a mop body that wipes and sweeps the floor through a universal joint at the lower end of the handle handle. The mop body is made of non-woven fabric, cloth, fiber / nylon / acrylic pile yarn, mouton wool etc. It is attached.

  In the cleaning work, the handle handle is operated to wipe and sweep the floor surface with the mop body, but it is inconvenient to work if the handle handle and the mop body are fixedly coupled. For this reason, the angle between the two can be varied using a universal joint. The universal joint has a handle handle that can be rotated 180 ° around one direction of the mop body, for example, when the mop body is rectangular, around the long side direction axis or around the short side direction axis (for example, Patent Documents) 1) and two directions, that is, those that can turn nearly 180 ° in two directions of the long side direction and the short side direction (for example, Patent Document 2).

  In case of a mop that the handle handle turns only in one direction with respect to the mop body, for example, when cleaning around the desk legs and the corners of the floor, the handle handle tilted from the floor is swung horizontally, and the tip mop A time-consuming operation of bringing the side of the main body into contact with a desk leg or a floor corner wall surface is required. In that case, it is often necessary to move the operator's standing position.

  In the case of a mop that turns the handle handle in two directions with respect to the mop body, the long side of the rectangular mop body can be tilted in the range of -180 ° to 180 ° with respect to the direction in which the tilted handle handle extends. However, for that purpose, an operation for twisting the handle pattern or stopping the twisting of the handle pattern is necessary. Further, since the vehicle turns only in the range of −180 ° to 180 °, the operation of the handle handle when cleaning around the leg of the desk and the corner of the floor is complicated and troublesome.

It is a figure which shows a motion of the mop 1 for cleaning at the time of cleaning a floor surface. The entire mop body 3 is slightly tilted from the floor 15. This is the movement of the mop body 3 when the area around the obstacle 20 is cleaned with the cleaning mop 1.

  Hereinafter, an embodiment of a cleaning mop according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of a cleaning mop 1 according to the present invention, and FIG. 2 is an exploded perspective view thereof. The cleaning mop 1 is composed of a handle handle 2, a mop body 3 for wiping and sweeping the floor, and a universal joint 4 connecting the two. FIG. 3 is an enlarged perspective view of the connecting portion of the handle handle 2, the universal joint 4, and the mop body 3.

  The handle handle 2 is a rod-like handle for operating the mop body 3, a grip portion 2 a for gripping is formed at the base end, and an end portion on the side of the universal joint 4 for connecting to the universal joint 4. A bifurcated portion 2b is formed. A screw through hole 2c is formed on the side surface of the bifurcated portion 2b.

  The mop body 3 has a wiping member 3b mounted on the lower surface side of a plastic or wooden rectangular base 3a. The wiping member 3b is formed of a fiber bundle assembly in which mop yarns that are thread-like or string-like strips are bundled, and is attached to the lower surface of the rectangular base 3a by adhesion, a hook-and-loop fastener, or the like. Sponges may be used instead of mop yarns depending on the application. A circular through hole 3d is formed at the center of the rectangular base 3a, and a circular bearing 3c having a thickness equal to the thickness of the base 3a is attached to the circular through hole 3d in a state where the outer ring is fixed to the base 3a. It is.

  The universal joint 4 is L-shaped when viewed from the side, and the L-shaped bottom part 4a is formed of a rectangular flat plate, and a screw through hole 4b is formed in the vertical direction near one short side. An L-shaped vertical side portion 4c is formed on the surface of the flat plate member of the L-shaped bottom side portion 4a near the short side opposite to the short side. The L-shaped vertical side portion 4c is a substantially rectangular plate material having a thickness equal to the interval between the bifurcated portions 2b of the handle handle 2 and is erected with its both surfaces parallel to the long side of the L-shaped bottom side portion 4a. The top part is formed in a semi-arc shape in a side view, and a screw through hole 4d is formed in the center of the semi-arc part.

  The cleaning mop 1 is constituted by connecting these three parts of the handle handle 2, the mop body 3, and the universal joint 4 as follows. First, a semi-arc-shaped portion of a plate material which is the L-shaped vertical side portion 4c of the universal joint 4 is inserted between the two forked portions 2b of the handle handle 2. In this state, the side screw through hole 2c of the bifurcated portion 2b and the central screw through hole 4d of the semicircular portion of the L-shaped vertical side portion 4c are aligned with each other, and the long screw 6 is formed from one outer surface of the bifurcated portion bifurcated portion 2b. Is inserted into the screw through holes 2c and 4d through the resin washer 6a. Next, the wing nut 7 is screwed into the screw portion of the long screw 6 protruding from the opposite side of the bifurcated portion 2b through the resin washer 6b, and the handle pattern is tilted from the vertical axis on the top surface of the rectangular base of the mop body. Tighten and fix with.

  The mop body 3 has a circular bearing 3c inserted into a circular through hole 3d provided at the center of the rectangular base 3a, and the outer ring and the base 3a are fixed to each other with an adhesive. The long screw 8 is inserted into the hole of the inner ring of the fixed circular bearing 3c from below. A washer 7a is attached to the screw portion of the countersunk screw 8 protruding above the inner ring of the circular bearing 3c, and the screw portion of the long screw 8 protruding on the washer 7a is connected to the screw through hole 4b of the L-shaped bottom portion 4a of the universal joint 4. Insert through. A wing nut 9 is screwed into the screw portion of the long screw 8 protruding above the screw through hole 4b of the L-shaped bottom side portion 4a via a washer 8b, and the rectangular base 3a is coupled with the long screw 8 as a rotation center axis. Tighten moderately on the lower side of 4 so that it can turn horizontally.

Finally, the cleaning mop 1 is completed by attaching the wiping member 3b to the lower surface side of the rectangular base 3a and attaching it with a hook-and-loop fastener or the like. As the long screw 8, a countersunk screw whose head appearance is a dish shape Should be used. The reason is that, even if the thickness of the screw portion is thin and a gap can be formed between the inner ring 3c1 of the circular bearing 3c, the center of the screw portion is positioned at the center of the inner ring 3c1 with a dish-shaped bowl as shown in FIG. Because it comes to do. FIG. 5 is a longitudinal sectional view including the center of the long screw 8 in a state in which the mop body 3 is attached to the L-shaped bottom part 4 a of the universal joint 4.

  6, 7, and 8 are diagrams showing another embodiment of the mop body 3. In the above embodiment, the wiping member 3b of the mop body 3 is attached to the entire lower surface of the rectangular base 3a with a fiber bundle assembly in which thread-like or string-like mop yarns as shown in FIG. 2 are bundled. used. On the other hand, in this another embodiment, two types of wiping materials are used for the wiping member 3b. FIG. 6 is a plan view of this as seen from the upper surface side. The planar shape is a rectangle, and is divided into two with the center line in the width direction as a boundary. A thick sponge 10a is used for one of the divided portions, and a flat brush 10b that extends obliquely downward toward the outside in the width direction at the other divided portion. Is used. The base of the flat brush 10b and the side surface of the thick sponge 10a are bonded back to back. FIG. 7 is a plan view of the mop body 3 in which the wiping member 3b having such a configuration is attached to the lower surface of the rectangular base 3a by adhesion, as seen from the upper surface side. The longitudinal dimensions of the wiping member 3b and the rectangular base 3a are the same.

  FIG. 8 is a longitudinal sectional view including the center of the long screw 8 in a state in which the mop body 3 having such a configuration is attached to the L-shaped bottom portion 4 a of the universal joint 4. The attachment method is slightly different from that of the above embodiment. In the embodiment, the head of the long screw 8 is positioned on the lower surface of the rectangular base 3a of the mop body 3, and the long screw 8 is attached without passing through the wiping member 3b. On the other hand, in this embodiment, the long screw 8 is attached through the wiping member 3b from the lower surface side of the wiping member 3b. For this reason, a hole through which the long screw 8 is passed is provided in a joint portion between the flat brush 10b as the wiping member 3b and the thick sponge 10a.

  Further, a short plastic conical part 11 having a diameter larger than the diameter of the head is attached to the head of the long screw 8. The head of the long screw 8 is embedded in the lower surface side of the plastic conical part 11, and the plastic conical part 11 is fixed to the head of the long screw 8 by this embedding. Since the diameter of the plastic conical part 11 is larger than the diameter of the head of the long screw 8, a hole large enough to accommodate it is provided at the joint between the flat brush 10b and the thick sponge 10a.

  The height of the plastic conical part 11 is slightly higher than the thickness of the thick sponge 10a and the flat brush 10b. For this reason, when the floor surface is cleaned with this cleaning mop, the top of the plastic conical part 11 is in contact with the floor surface. However, since the length of the top portion protruding slightly below the thick sponge 10a and the flat brush 10b is slight, the grip portion 2a of the handle 2 is pulled slightly forward to slightly tilt the surface of the rectangular base 3a of the mop body 3. Then, the thick sponge 10a or the flat brush 10b comes into contact with the floor surface and cleaning is performed. Which of the thick sponge 10a and the flat brush 10b is brought into contact with the floor surface can be selected by an operation before the surface of the rectangular base 3a is slightly inclined. The reason why the top portion of the plastic conical part 11 is in contact with the floor surface is to facilitate the horizontal turning of the mop body 3.

  The characteristic of the cleaning mop 1 described above is that the mop body 3 is configured to be horizontally rotatable by a circular bearing 3c. For this reason, when a part of the mop body 3 comes into contact with an obstacle when cleaning around a leg of the desk, around an article placed on the floor, a corner of the floor, etc., a reaction force from the obstacle is received. The mop body 3 automatically turns in the direction along the side of the obstacle. At the time of this turning, the conventional cleaning mop requires operations such as twisting operation of the handle 2, twisting prevention operation, changing the direction of the handle 2, etc., but the cleaning mop 1 of the present embodiment requires these operations. There is an advantage that no operation is required.

  Thus, in the structure in which the mop body 3 rotates horizontally, there is a concern that when the floor surface without an obstacle is cleaned, the mop body 3 rotates horizontally and the operation becomes difficult. However, in such a case, the mop body 3 does not swivel. 9, 10 and 11 are diagrams for explaining the reason. FIG. 9 is a side view of the state in which the handle handle 2 is operated so that the entire lower surface of the mop body 3 is in contact with the floor surface 15. However, the mop body 3 does not move on the floor surface 15 in such a posture.

  Usually, when cleaning the floor surface 15 without an obstacle, the operator holds the handle pattern 2 with the right hand, moves the handle pattern 2 back and forth, and cleans the floor surface 15 while moving the mop body 3 back and forth. Do. Therefore, when the handle pattern 2 is operated with the right hand and the mop body 3 is pushed forward from near the feet, the mop body 3 moves forward and the upper end of the handle pattern 2 is slightly lower as shown in FIG. Move to. Since the universal joint 4 is fastened and fixed to the handle handle 2, when the height of the upper end of the handle handle 2 is lowered, the opening angle between the lower surface of the mop body 3 and the floor 15 is as shown in the side view of FIG. θ is generated. When the mop body 3 is inclined by θ with respect to the floor surface 15, the long screw 8 that is the rotation axis of the circular bearing 3 c is also inclined by θ from the vertical direction. When the long screw 8 that is the rotation shaft is tilted from the vertical direction, the lower surface of the operator side end of the mop body 3 is in contact with the floor surface 15, so that the mop body 3 cannot turn horizontally. Then, the handle pattern 2 extends in a direction perpendicular to the direction in which the handle pattern 2 is pushed out, that is, the direction in which the handle is pushed out, and moves while maintaining the posture. For this reason, in a normal cleaning operation in which the floor surface without an obstacle is cleaned while moving the handle handle 2 back and forth, an operation in which the mop body 3 pivots horizontally does not occur.

  When the handle pattern 2 is pushed forward, an angle of θ between the lower surface of the mop body 3 and the floor surface 15 causes the following effects. That is, in the conventional cleaning mop, the mop body 3 performs cleaning by moving back and forth with the entire lower surface in contact with the floor surface 15 as shown in FIG. This is because the mop body 3 is joined by a joint whose angle between the upper surface and the handle 2 is freely changed. In such a cleaning method, the dust and dirt present on the floor 15 may be pushed forward at the front end of the wiping member on the lower surface of the mop body 3. In order to prevent this, the wiping member has been processed so that dust or dust adheres to the wiping member, or the wiping member is wetted with water. However, even in such a case, dust or dust adheres only to a part of the front end of the wiping member. That is, only a part of the wiping member contributes to dust and dust removal. On the other hand, in the cleaning mop 1 according to the present embodiment, when the handle handle 2 is pushed forward, an angle θ is generated between the lower surface of the mop body 3 and the floor surface 15, so that it exists on the floor surface 15. Dust and dust collide with the wiping member 3b at the center of the lower surface of the wiping member 3b and are captured. Since it collides with and is captured by the wiping member 3b at the center of the lower surface, it is not pushed forward. Moreover, since it captures in the lower surface center part vicinity, the whole lower surface of the wiping member 3b will contribute to removal of dust and dust, and is efficient.

  FIG. 12 is a view for explaining the movement of the mop body 3 when cleaning around an obstacle such as a desk leg. The mop body 3 is brought close to the obstacle 20 as shown in (1) of FIG. When approaching the obstacle 20, the upper end of the handle handle 2 of the mop body 3 is slightly lifted so that the entire lower surface of the mop body 3 is in contact with the floor 15 as shown in FIG. In this state, the mop body 3 can be turned horizontally by the circular bearing 3c. From this state, the handle 2 is moved forward and moved forward with one side of the mop body 3 (the right side in the case of FIG. 12) being in contact with the obstacle 20. Then, as shown in FIG. 12 (2), the mop body 3 starts to turn horizontally. When the handle 2 is further advanced, the mop body 3 is in a state where the wiping member 3b of the mop body 3 is in contact with the obstacle 20 as shown in FIG. 12 (3a) or FIG. 12 (3b). The part close to the left side surface of the obstacle 20 is cleaned. Whether the posture is (3a) in FIG. 12 or (3b) in FIG. 12 is determined by the distance between the left side surface of the obstacle 20 and the turning center of the mop body 3. When the mop body 3 is in such a posture, the cleaning mop 1 according to the present embodiment performs operations such as twisting the handle 2, preventing twisting, and changing the advancing direction of the handle 2. do not need. It is possible to clean the vicinity of the side surface of the obstacle 20 with a simple operation by simply moving the mop body 3 in a state where one side of the mop body 3 is in contact with the obstacle 20. To return to the state of (1) of FIG. 12 from the posture of (3a) in FIG. 12 and (3b) in FIG. 12, the upper end of the handle handle 2 is slightly pushed down, and the lower surface of the mop body 3 is the floor surface as shown in FIG. What is necessary is just to pull the handle pattern 2 to the near side in a state slightly inclined with respect to 15.
