Description

  The present invention relates to a cleaning tool used for cleaning a floor surface or the like.

  Some cleaning tools used for wiping the floor or the like include a support rod, a cleaning head connected to the support rod via a universal joint, and a wiping cloth provided in the cleaning head. The cleaning head includes a main body and an elastic body provided on the lower surface of the main body. The wiping cloth is wound around the main body and the elastic body, the central portion in the width direction is disposed on the lower surface of the elastic body, and both end portions in the width direction are wound on the main body and locked to the main body.

  By the way, in the said prior art, there is nothing which can latch (fix) a wiping cloth to a main body easily and reliably, and the improvement regarding this point was requested | required.

  The problem to be solved is that the wiping cloth cannot be easily and reliably locked to the main body.

The present invention solves the above-described problems, and is characterized in that the wiping cloth is wound around the cleaning head and is detachably locked. Is provided with a locking portion that is detachably locked to the wiping cloth, and a linear slit extending from the substantially central portion of the locking portion to the outer periphery thereof is provided in the circumferential direction. The one end of the slit is in contact with the adjacent slit, and the position of each contact point of the adjacent slit is different at the approximate center of the locking portion. A zigzag zigzag portion formed by the center side end portion of the slit is formed in the center portion, and an elastic tongue piece that is elastically deformable in the inner and outer directions of the cleaning head is formed between adjacent slits in the locking portion. Is a point.
In addition, the angle which an adjacent slit makes may be 30-110 degrees.

According to the present invention, since the zigzag zigzag portion constituted by the center side end portion of the slit is formed in the substantially central portion of the locking portion, only the wiping cloth is pushed into the substantially central portion of the locking portion. Then, the zigzag portion bites into the wiping cloth in a zigzag manner, and locks and fixes the wiping cloth. Thereby, the wiping cloth can be easily and reliably locked and fixed to the locking portion.
Further, in the present invention, the slit itself is linear, and the position of each contact point of the adjacent slit is different, so that the slit is formed at the center side end of the slit at the substantially central portion. A zigzag portion is formed. Thus, in the present invention, since the zigzag portion is formed with a simple configuration, the zigzag portion can be formed easily and at low cost.

  The present invention provides a cleaning tool capable of easily and reliably locking and fixing a wiping cloth to a main body.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a cleaning tool includes a support rod (handle) 1 and a universal joint (or spherical bearing) 2 on the support rod 1. And a wiping cloth 4 wound (wound) around the cleaning head 3 and used for wiping the floor surface or the like. This floor surface is a concept that includes all of the conventional cleaning tools of this type, such as flooring such as flooring, tatami mats, and vinyl floors, wall surfaces, ceiling surfaces, and the like.

  The support rod 1 is hollow and has a plurality of connecting pipes 6, which are connected in a separable manner.

  The cleaning head 3 has a main body 8 and an elastic body (intervening body) 9.

  As shown in FIGS. 3 to 5, the main body 8 is formed of a synthetic resin such as high-density polyethylene, polypropylene, and ABS resin (acrylonitrile butadiene styrene), and is integrally formed by, for example, injection molding. The main body 8 is formed in a rectangular shape in plan view, but the shape in plan view of the main body 8 may be a circle, an ellipse, a square, or a polygon that is a pentagon or more. The central portion of the upper surface of the main body 8 is a recessed portion 11 that is recessed downward, and the central portion of the recessed portion 11 is connected to the support rod 1 via the universal joint 2, thereby supporting A cleaning head 3 is rotatably provided on the rod 1.

  A portion of the main body 8 excluding the recessed portion 11, i.e., the outer peripheral portion, has a hollow shape that opens downward, and the four corner portions of the wiping cloth 4 are detachably locked to the four corner portions of the outer peripheral portion. A locking portion 13 is provided. Each locking portion 13 is made thinner than other portions, and a space 14 for pushing the wiping cloth 4 is formed below the locking portion 13.

  As shown in FIG. 6, six linear slits (cuts) 15 to 20 are arranged in the locking portion 13 at intervals in the circumferential direction, and between adjacent slits 15 to 20 The elastic tongue pieces 21 to 26 are elastically deformable in the direction (inside and outside of the main body 8). The slits 15 to 20 extend from the substantially central portion of the locking portion 13 to the outer peripheral portion. At the substantially central portion of the locking portion 13, one end of each of the slits 15, 16, 18, and 19 is adjacent to the adjacent slits 15 to 20. Since the positions of the contact points (intersection points) 27 to 30 of the adjacent slits 15 to 20 are different from each other, the slits 15, 17, 18, and 20 are formed at substantially the center of the locking portion 13. A zigzag (wave shape) zigzag portion (corrugated portion) 31 formed by the center side end portion is formed. FIG. 7 is a schematic diagram of the locking portion 13, and the thick line portion indicates the zigzag portion 31. The angle formed by the adjacent slits 15 to 20 is 30 ° to 110 °, but the center side angle of the elastic tongue pieces 21, 22, 24, 25 is set to an acute angle of 30 ° or more and 90 ° or less, and is elastic. If the tongue pieces 21, 22, 24, 25 are sharpened, the elastic tongue pieces 21, 22, 24, 25 can easily bite into the wiping cloth when the wiping cloth 4 is locked, which is preferable. In this embodiment, the slits 17 and 20 are continuous on the same straight line, the slits 16 and 19 are arranged on the same straight line at intervals, and the slits 15 and 18 are arranged on different straight lines. However, all the slits 15 to 20 may be arranged on different straight lines.

  The elastic body 9 is disposed below the main body 8 and is fixed to the central portion of the lower surface of the main body 8 with a double-sided tape, an adhesive, or the like, and is made of an elastic material such as synthetic rubber, sponge, or urethane foam. And a foamed resin such as foamed polyethylene. The elastic body 9 abuts on the object to be cleaned through the wiping cloth 4 during cleaning, thereby reducing the possibility that the object to be cleaned will be damaged due to contact with the cleaning head 3 and the object to be cleaned. The elastic body 9, that is, the wiping cloth 4 fits well with respect to the concavo-convex surface and the curved surface, so that these surfaces can be wiped well.

  The wiping cloth 4 collects dust on the floor surface, etc., and synthetic fibers such as polyethylene and polyethylene terephthalate, regenerated fibers such as rayon, natural fibers such as cotton, pulp and the like alone or Arbitrary things are used from the sheet-like nonwoven fabric, the woven fabric, etc. which were manufactured by mixing. Since the wiping cloth 4 is used for cleaning, it is preferable that the cloth has excellent dust absorption and wear resistance. Although the magnitude | size of the wiping cloth 4 is not specifically limited, At least the magnitude | size which can latch the four corner parts of the wiping cloth 4 to each latching | locking part 13 of the main body 8 is required. The wiping cloth 4 may be impregnated with a chemical dusting agent.

  According to the above configuration example, when the wiping cloth 4 is locked to the locking portion 13, the wiping cloth 4 is pushed into the substantially central portion of the locking portion 13 to elastically deform the elastic tongue piece 21 downward. Then, when the pressure on the wiping cloth 4 is released, the elastic tongue piece 21 is elastically restored upward, whereby the wiping cloth 4 is clamped by the elastic tongue piece 21 as shown in FIG. Locked and held.

  In this case, since the zigzag-shaped zigzag portion 31 constituted by the center side end portions of the slits 15, 17, 18, and 20 is formed at the substantially central portion of the locking portion 13, the locking portion 13 is substantially omitted. The zigzag portion 31 bites into the wiping cloth 4 in a zigzag manner simply by pushing the wiping cloth 4 into the center, and locks and fixes the wiping cloth 4. Thereby, the wiping cloth 4 can be easily and reliably locked and fixed to the locking portion 13.

  Further, in the embodiment, the slits 15 to 20 themselves are linear, and the positions of the respective contacts (intersections) 27 to 30 of the adjacent slits 15 to 20 are made different so that the approximate center of the locking portion 13 is obtained. A zigzag (wave shape) zigzag portion (wave shape portion) 31 constituted by the center side end portions of the slits 15, 17, 18, and 20 is formed in the portion. That is, in the embodiment, since the zigzag portion 31 is formed with a simple configuration, the zigzag portion 31 can be formed easily and at low cost.

  When the wiping cloth 4 is unlocked by the locking portion 13, it is easy to lock the wiping cloth 4 by the locking portion 13 if a force is applied to separate the wiping cloth 4 from the locking portion 13. Can be released.

  In the embodiment, the cleaning head is composed of the main body and the elastic body. However, the main body itself may be used as the cleaning head without the elastic body.
