Description

  The present invention relates to a cleaning tool in which a wiping body insertion portion is detachably inserted into a bag portion of a wiping body for cleaning a floor surface and a wall surface, and in particular, a wiping body insertion portion in which the wiping body insertion portion is rotatable. The present invention relates to a rotary cleaner.

Conventionally, as this type of cleaning tool, a handy type or a hook-shaped long handle type has been widely used. For example, Patent Document 1 discloses a long handle type cleaning tool.
FIG. 13 shows a long handle type cleaning tool. 13A and 13B respectively show a pile wiping body 40, and FIG. 13B shows a long handle 41 for fixing and holding the pile wiping body 40.

  The wiping body 40 includes an elliptical base cloth 42 and a large number of piles 44 planted on the lower surface of the base cloth 42. The base fabric 42 is formed by weaving cotton fibers or synthetic fibers in a mesh shape, and on the upper surface of the base fabric 42, bag-like insertion portions 43, 43 made of the same fiber type are provided.

  The long handle holder 41 includes a mounting portion 45 attached to the base cloth 42 and a pipe-like handle 47 for manual operation. A grip 48 is provided on the distal end side of the handle 47. The tip of the handle 47 is pivotally supported by the mounting part 45 via the joint part 46. The mounting portion 45 is made of a substantially elliptical oval plate having a joint portion 46 protruding therefrom. By inserting both end portions of the mounting portion 45 into the bag-like insertion portions 43 and 43, the wiping body 40 is mounted on the long handle holder 41 to constitute a long handle handle type cleaning tool. In particular, when the wiping body is periodically replaced and rented from a manufacturer or the like to the user, the wiping body 40 needs to be separable from the handle. In order to simplify the work at the time of replacement and cleaning, the wiping body 40 is made detachable with respect to the mounting portion 45 at the end of the handle.

JP 2005-270630 A JP-A-10-328108 JP 2002-65545 A

In the state where the wiping body 40 is mounted on the mounting portion 45 in the conventional cleaning tool, most of the piles 44 are located on the back side of the mounting portion 45. Moreover, the tip of the handle 47 is fixed and held with respect to the mounting portion 45 via the joint portion 46, and does not have a degree of freedom to move around the long axis of the mounting portion 45.
However, in this conventional cleaning tool, the handle 47 can be tilted in the longitudinal direction of the mounting portion 45, but cannot be rotated around the long axis of the mounting portion 45. In order for the wiping surface of the pile 44 to come into contact with the floor surface or the like, it is necessary to always perform the cleaning work while paying attention to the force that moves the handle 47, and there is a problem that the smooth cleaning work is hindered.

FIG. 14 shows a state in which the handle 47 is laid on the floor 49 and cleaned when the gap 51 such as furniture such as furniture is cleaned with the cleaning tool. (15A) of FIG. 15 shows the side surface of the cleaning tool in which the handle 47 is inclined at the laying angle θ.
In cleaning the gap, the laying angle θ with respect to the floor 49 is often set to 45 ° or less. In order to clean every corner of the gap 51 in such a laid state, it is necessary to hold the handle 47 and move it while rotating it so that it traces on the floor 49 as indicated by the arrow 50. When the handle 47 is vertically set on the joint portion 46, if the handle 47 is turned around the vertical axis, the wiping body 40 also rotates following the rotation. However, since the mounting portion 45 is inserted in close contact with the bag-like insertion portions 43, 43, the handle 47 is held in the direction of the arrow 50 as shown in FIG. The wiping body 40 and the mounting portion 45 move integrally even if it rotates, and the movement of the wiping body 40 stops at the floor surface portion on the front side in the rotation direction, as shown by the broken line in (15B), The wiping body 40 floats on the floor surface portion on the rotation start side in response to the frictional resistance with the floor surface and floats in the air, and a smooth rotation operation cannot be performed.

  In the case of the conventional cleaning tool, the handle 47 is disposed in a T-shape with respect to the wiping body 40 in a state where the mounting portion 45 is attached to the wiping body 40 so that the handle 47 can be rotated back and forth and right and left. Therefore, a joint portion 46 is formed on the mounting portion 45. However, since the joint portion 46 is formed on the mounting portion 45, the pivotal connection point is located above the mounting portion 45, and even if a force is applied with the handle 47, the mounting portion 45 slides upward. As a result, there is a problem in that it is difficult to sufficiently apply the force for smoothly performing the rotation operation to the mounting portion 45.

  Patent Document 2 discloses a cleaning tool that rotatably supports a mop shaft of a cleaning mop formed in a roller shape. In this cleaning mop, after a braid is fitted to each of a bent part of the wire in a U-shape and each end of the wire, a synthetic fiber bundle cut into a predetermined length inward of the U-shape The wire is twisted across the (cleaning yarn), the wire end is bent inward and the end is covered with braid, and the synthetic fiber bundle is centered on the mop shaft. It is formed to spread radially. However, in this cleaning tool, although the cleaning mop can be rotated to the floor plane by a roller rotation method using rolling friction, the synthetic fiber bundle is integrally formed with the mop shaft in the form of a roller. In addition to processing costs such as material costs and wire twisting, it is necessary to replace the mop for cleaning with the mop shaft after use, and it cannot be applied to rental products in which only synthetic fiber bundles are collected and reused.

  In Patent Document 3, a head in which a rod-like head main body is inserted into a cylindrical base portion of a mop body is formed, and then this head is formed into a cylindrical clamp main body in which one cylinder side portion of the head holder is vertically cut out. There has been disclosed a cleaning tool that is assembled by pressing against a notch, expanding the notch once by its elasticity, and holding the center of the head. In this cleaning tool, the notch portion of the cylindrical clamp body which is the head holder is gripped in a state where the cylindrical base portion is put on the rod-like head body as the head core material, so that the rotation connection point is the head of the head. A force required for head operation is easily applied to the head in the vicinity of the central axis. However, since the rod-shaped head main body is inserted into the cylindrical base of the mop body, the rod-shaped head main body as the head core material moves integrally with the mop body, and the frictional resistance with the floor surface causes the case of FIG. Similarly, at the time of rotational cleaning of the floor surface, one end of the head is lifted from the floor surface and a smooth rotation operation cannot be performed.

  The present invention has been made in view of the above problems, and when the handle is gripped to clean a narrow space such as a fixture, the wiping body can be easily rotated on the cleaning surface to be simple and light.

The grip 5 is attached to the upper end of the outer pipe 4 by fitting the grip removal preventing piece 7 also serving as a cover into the hole 4 a provided on the upper end side of the outer pipe 4 from the opening on the lower end side of the grip 5.

In the cleaning tool having the above-described configuration, the insertion shaft body includes a pair of rotating shaft bodies 10 and 11 that are coupled laterally at both ends of the connecting member 20 and a pair of outer shaft bodies 10 and 11 that are externally fitted to the rotating shaft bodies 10 and 11. The hollow bodies 12 and 13 are configured in such a manner that, by these double structures, the hollow bodies 12 and 13 are pivotally supported on the rotary shaft bodies 10 and 11 so as to be able to rotate independently of each other. It arrange | positions symmetrically with respect to the connection member 20, and is provided in T shape or substantially T shape with respect to the long handle 2. Accordingly, when the narrow handle 2 is gripped to clean a narrow space such as a fixture, the long handle 2 moves when the handle 2 is tilted at an acute angle with respect to the wiping body 1 and rotated on the cleaning surface. Accordingly, the hollow bodies 12 and 13 can be rotated so as to draw an arc while rotating inside the bag portion 23 by the pivotal support mechanism of the rotary shaft bodies 10 and 11, so that cleaning is simple and light. Work can be done. Moreover, since the rotary shafts 10 and 11 are horizontally arranged via the connecting member 20 and are inserted into the bag portion 23, the rotation connecting point of the long handle 2 is connected to the rotary shafts 10 and 11. It is located very close to the horizontal axis, and the force applied by the long handle 2 can be accurately applied to the insertion shaft body, and the rotation operation is performed more smoothly in synergy with the rotation function of the pivot mechanism. be able to.
Further, in the T-shaped or substantially T-shaped cleaning tool, the insertion shaft body as the wiping body insertion portion is paired with a pair of rotating shaft bodies 10 and 11 and a pair of rotating shaft bodies 10 and 11 that are externally fitted. Since the hollow bodies 12 and 13 are configured, the wiping body insertion portion can be rotated with a simple and inexpensive structure, and the handle rotation mechanism can be integrally provided to be tiltable.

  FIG. 12 shows the measurement result of the rotational operation function of the cleaning tool according to this embodiment. In this measurement, a comparison with the prior art in FIG. 13 was performed. That is, using the cleaning tool according to the present embodiment and the cleaning tool of FIG. 13, the cleaning was attempted by laying the handle on the floor surface, and the cleaning effective areas were compared. The cleaning effective area of 100% represents that the cleaning tool can be rotated to clean the entire floor without any spots. In FIG. 12, “head” means the wiping body and the wiping body insertion portion, and “sleeve” means the hollow bodies 12 and 13. Moreover, the laying angle of the handle with respect to the floor surface was tried at 30 °, 45 °, and 60 °.

In the case of the conventional head fixing described with reference to FIG. 14, the rotation operation can be performed when the laying angle is 60 °, but when the laying angle is inclined by 30 ° or 45 °, the “head” is lifted and cleaned. The effective area was reduced to 65 to 90% (see (1) in FIG. 12). On the other hand, in the cleaning tool according to the present embodiment, smooth rotation operation is possible at any of the laying angles of 30 °, 45 °, and 60 °, and the cleaning effective area can be maintained at 100%. The rotation angle of the hollow bodies 12 and 13 itself at this time also becomes larger as the laying angle is steeply inclined to 60 °, 45 ° and 30 °, and the rotation of the hollow bodies 12 and 13 contributes to a smooth rotation operation. (See (2) in FIG. 12).
In addition, as shown in FIG. 8 (8D), the cross-sectional shape of the hollow bodies 12 and 13 is such that protrusions (ribs) 12b that contact the inside of the bag portion 23 are formed on the outer surface of the hollow body 12a. The same rotational operability was verified. The six protrusions 12b are formed along the outer periphery of the hollow body 12a. According to this verification experiment, as shown in FIG. 12 (3), the same effective results as the hollow bodies 12 and 13 without ribs were obtained with respect to the cleaning effective area. Therefore, if the hollow body 12a with ribs is used, for example, in the case of rental products, the interior of the bag portion 23 is extended by repeated cleaning or the like, and the insertion state of the insertion shaft body is loosened. However, following the movement of the handle, the projecting portion (rib) 12b can be rotated to draw an arc by rotating inside the bag portion 23 while contacting the inside of the bag portion 23. A rib formed on the outer surface of the hollow body 12a in a spiral shape can be used in addition to the ribs spaced apart from each other like the protrusion 12b.

  Although the cleaning tool of the present embodiment is a case of a long cleaning tool, the present invention can be applied to a short cleaning tool or a handy type cleaning tool. In addition, a chemical fiber material or the like can be used.

  The present invention is not limited to the above-described embodiments and modifications, and includes various modifications and design changes within the technical scope without departing from the technical idea of the present invention. Needless to say.

  The cleaning tool according to the present invention is used when cleaning the flooring of a home, office or factory, the floor of a store, and the like. It ’s good.
