Description

  The present invention relates to a cleaning instrument that can be used as a substitute for a scissors while detachably attaching a wiping material made of fiber cloth to a cleaning head part to clean a floor surface and the like.

  Conventionally, as a cleaning instrument, a non-woven cloth wiper is detachably attached to the cleaning head part with handle, and by moving it along the floor surface, dirt and dust on the floor surface are attached to the wipe material. What is called a so-called “cleaning sheet” is used.

  For example, in Patent Document 1 below, the cleaning head portion is composed of a flat rectangular box-shaped holding portion with a handle, and an elastic body attached to the lower surface portion of the holding portion. A method is disclosed in which a plurality of convex portions bulging in a hemispherical shape are formed on the surface. When cleaning the floor or carpet, this cleaning tool covers the surface of the elastic body with a non-woven wipe and moves the cleaning head along the floor to be cleaned. If the surface of the elastic body is not flat, the elastic body is deformed, or if the surface of the elastic body is complicated like a carpet, the surface of the elastic body can be cleaned by biting between long hairs. .

  Patent Document 2 shown below is a cleaning instrument having a configuration substantially similar to that of Patent Document 1, but a plate-like elastic body made of urethane foam is provided on the lower surface portion of the holding portion, and the surface of this elastic body is placed inside. In addition to being formed in a convex shape, a very large number of small convex portions (each convex portion having a diameter of 1 mm to 2 mm and a height of 1.3 mm to 1.8 mm) are formed on this surface. Is a hemispherical convex part with a depression at the top, and the convex part itself is easily deformable by this depression, and even when it is pushed or pulled in the front-rear direction or moved in the left-right direction with respect to the floor surface etc. The portion is easily deformed and can be cleaned without causing a gap between the surface and the non-woven cloth wipe.

Japanese Patent Laid-Open No. 9-140650 Japanese Patent No. 3027345

  However, as in Patent Document 1, when an elastic body is provided in the cleaning head, an elastic feeling is generated when contacting the floor surface, and a pin without a gap is stretched between the elastic body and the wiping material. If the surface on the floor contact side of this elastic body is flat, the center part will be insufficiently contacted, and the entire surface will not be able to be cleaned uniformly, and only at the outer peripheral part. Tend to be cleaning.

  If the elastic body is formed in a middle convex shape as in Patent Document 2, it is possible to prevent such a point that the center portion is insufficiently hit, but equipment such as a mold for molding the elastic body becomes expensive. , Disadvantageous to product cost. In addition, if a large number of extremely small hemispherical protrusions are formed on the elastic body, it cannot be denied that the mold is disadvantageous in terms of cost.

  In particular, the cleaning tool is convenient and convenient when it has multiple functions in general, but in the case where a hemispherical convex portion is formed on an elastic body as in Patent Document 1, an elongated gap is used. You can't scrape out any trash that you can't use as a bag. Further, as in Patent Document 2, even if the elastic body itself is made of urethane foam, if it is an extremely small hemispherical convex portion, the deformation margin of the convex portion itself is small, and the convex portion itself is substantially elastically deformed. For example, in the case where the object to be cleaned has a part that is easily damaged or has a small uneven part, it cannot be used practically and has poor versatility. It has become.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a versatile cleaning tool that is advantageous in terms of manufacturing man-hours, equipment, or product cost.

  In the first aspect of the present invention, a number of elastically deformable elastic protruding pieces having a flat plate shape are protruded from the substrate member, and the elastic protruding pieces are aligned and arranged along the longitudinal direction of the substrate member. When a wiping material is not attached, it is possible to easily scrape dust that has entered a narrow gap using a flat plate-like elastic protruding piece, and the elastic protruding piece itself can be elastically deformed. By using this point, it can also be used as a scissors, and if the protrusion length of the elastic protruding piece is increased to increase the deformation allowance, even if the object to be cleaned is easily damaged or uneven, it is easily cleaned can do. Furthermore, if a wiping material is attached so as to cover the elastic protruding piece, it can be used as a cleaning sheet having a relatively large elastic width without generating a gap between the elastic protruding piece and the wiping material. Therefore, it can be used not only as a so-called “cleaning sheet” but also as a bag, and becomes a versatile cleaning tool. In addition, since each elastic protruding piece has a relatively simple shape such as a flat plate shape, the mold is also inexpensive, which is advantageous in terms of manufacturing man-hours, equipment, and product cost.

  In the invention of claim 2, the elastic protruding pieces are arranged at equal intervals in the longitudinal direction of the holding portion, in a staggered arrangement in the direction orthogonal to the longitudinal direction, and a part of the front and rear elastic protruding pieces overlap. When used as a bag, there is no possibility that dust or the like passes through the gap between the elastic protruding pieces, and the dust collection capability is improved.

  In the invention of claim 3, since the pillow-like protrusion is formed on the lower surface end of the holding part and the elastic protrusion piece is provided so as to protrude from the pillow-like protrusion, the elastic protrusion piece when covered with a wiping material In addition to being able to be in a tensioned state without creating a gap between the wiping material, the wiping material is held in a medium-high shape, and the tendency for the center portion to be insufficiently prevented is prevented, so that the entire surface hits uniformly. It becomes a cleaning sheet.

  In invention of Claim 4, since the said elastic protrusion piece was integrally shape | molded with the board | substrate member and the synthetic resin, if an elastic-body part is removed from the head part for cleaning, this can be wash | cleaned, and it is as a clean cleaning instrument. Can be used.

The bottom plate 9 is provided integrally with the both side plates 8a and 8b. The bottom plate 9 is basically composed of a flat plate material. However, a pillow-like projection 12 formed integrally with the side plate 8 a is provided at the end in the longitudinal direction of the holding portion 5, and the holding portion 5. As shown in FIG. 4, a protrusion 13 is provided at the end on the direction side perpendicular to the longitudinal direction of the head.

  As shown in FIG. 3, the pillow-like protrusion 12 is provided so as to protrude beyond the bottom plate 9, and comes into contact with and firmly holds the wiping material 6 when it is attached.

  When the pillow-like protrusion 12 and the protrusion 13 are provided on the bottom plate 9 in this way, a recess having a flat surface is formed on the lower surface of the bottom plate 9, so that the elastic body 20 is attached in the recess. ing.

  In particular, as shown in FIG. 3, the elastic body 20 of the present embodiment is detachably attached to the lower surface of the bottom plate 9, and has a substrate member 21 having the same rectangular shape as the holding portion 5, and the substrate member 21. A plurality of elastically deformable elastic projecting pieces 23 projecting downward from the surface and formed in a flat plate shape are integrally formed of an elastic material such as natural rubber or synthetic rubber.

  As shown in FIG. 3, the board member 21 is provided with a protruding member 22 on the upper surface, the protruding member 22 is inserted into a through hole O provided in the bottom plate 9, and a large-diameter head provided on the top of the protruding member 22.

  Here, regarding the size of the substrate member 21 and the elastic protruding piece 23 in the present embodiment, this is exemplarily shown. As shown in FIG. 6, the length L in the longitudinal direction of the substrate member 21 is about 22 cm. ˜23 cm, width W is about 7 cm˜8 cm, and for each elastic protruding piece 23, the length a in the longitudinal direction is 10 mm, the interval b between each other is 5 mm, and the interval b in the direction perpendicular to the longitudinal direction is 5 mm, wall thickness t is 1 mm, height H (see FIG. 3) is 15 mm, protrusion length h from the pillow-like protrusion 12 is about 7 mm, and the elastic protrusions 23 are arranged evenly on almost the entire surface of the substrate member 21. ing.

  Next, the operation will be described.

  First, the cleaning tool of the present embodiment can be used as a so-called “cleaning sheet”. In this case, the lower surface side of the elastic body 20 of the cleaning head portion 4 is covered with the wiping material 6. For example, one end of the wiping material 6 is gripped with a finger or the like, and this is pushed into the holding portion 10, and the one end of the wiping material 6 is fixed to the cleaning head portion 4. Next, the other end portion of the wiping material 6 is grasped with a finger or the like, the elastic protruding piece 23 protruding from the lower surface of the cleaning head portion 4 is covered, and the other end portion is pushed into the holding portion 10 and fixed.

  The wiping material 6 attached in this manner is provided. The wiping material 6 is in a state along the side plate 8a and the pillow-shaped protrusion 12 at the end portion in the longitudinal direction, and the portion covering the elastic protruding piece 23 is tightly stretched by the elasticity of the elastic protruding piece 23. Therefore, when the cleaning head portion 4 is installed on the floor surface, the elasticity is transmitted to the hand and the usability is good, and when the cleaning head portion 4 is moved along the floor surface, it can be slid easily. In particular, the longitudinal end portion of the wiping material 6 extends along the pillow-shaped protrusion 12 and reaches the lower surface of the elastic protruding piece 23, so that it becomes a medium-high shape as shown in FIG. Therefore, there is no possibility that the state where the central portion of the lower surface of the cleaning head portion 4 does not hit the floor surface will occur.

  Therefore, the cleaning operation can be performed comfortably even on a relatively large floor. Further, since the elastic protruding piece 23 holds the wiping material 6 due to its elasticity, the wiping material 6 has great elasticity, so even if it is relatively easy to clean, it can be performed without problems. it can.

  When the cleaning is completed in this way, the wiping material 6 is removed from the cleaning head portion 4. At this time, if the substrate member 21 is also removed from the cleaning head portion 4, it can be cleaned, and the cleaning head portion. 4 can be stored cleanly.

  Next, if dust, dust, etc. are present on the floor, the wiping material 6 is not attached to the cleaning head part 4 and the sweeping is performed with a large number of elastic protruding pieces 23 exposed from the lower surface of the cleaning head part 4. You can also. That is, the cleaning instrument 1 of the present embodiment can be used as a bag.

  If the wiping material 6 is not attached to the cleaning head part 4 and the elastic protruding piece 23 is exposed from the cleaning head part 4, the elastic protruding piece 23 protrudes from the lower surface of the cleaning head part 4. Can be used as an alternative to firewood. If the long side of dust, dust, etc. is used on the floor, dust, dust, etc. can be collected from a relatively wide range. In this case, in the cleaning head section 4, the elastic protruding piece 23 is perpendicular to the longitudinal direction. Since the front and rear elastic protruding pieces 23 are partially overlapped with each other, dust and dust are efficiently collected without escaping from the gaps between the elastic protruding pieces 23. Can do.

  Further, even when used as a basket, when there is a long and narrow gap between the boards as in the floor of the board, and when dust or the like enters the gap, the longitudinal direction of the cleaning head section 4 When the elastic protruding piece 23 arranged in a direction orthogonal to the gap is moved along the gap between the plates, dust and the like can be easily scraped out from the gap.

  The present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art within the technical idea of the present invention. For example, in the above-described embodiment, the elastic protruding pieces 23 are arranged in a staggered manner in the direction perpendicular to the longitudinal direction of the holding portion 4 and are arranged so that a part of the front and rear elastic protruding pieces 23 overlap. Not only that, but all of the elastic protruding pieces 23 may be in a state in which the flat surface is disposed along the longitudinal direction of the holding portion 5. Further, the protruding length of the elastic protruding piece 23 protruding from the substrate member 21 can be adjusted as appropriate. If the elastic protruding piece 23 has a long protruding length, it has a high scissors performance and is easily damaged. Can be easily cleaned. Further, in order to give a certain degree of rigidity to the elastic protruding piece 23 itself whose flat surface is arranged along the longitudinal direction of the holding portion 5, all or an appropriate number of elastic protruding pieces 23 are provided with support columns. You may comprise so that it may become a "ten" shape.
