Abstract
Description
[Technical field]
[0001] The present invention relates to a cleaning sheet that can be attached to slippers or cleaning tools, and more particularly to a cleaning sheet that can be detachably attached to the underside of slippers or the like. [Background technology]
[0002] Conventionally, floor wiping has been done by a person getting on all fours with a dustcloth or by using a mop or other long stick with a wiping cloth attached to the end. These cleaning methods place a great burden on the body and require storage space for the cleaning tools, so a cleaning sheet has been proposed that can be attached to the bottom of indoor footwear such as slippers and used to wipe while wearing the footwear. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication No. 2019-141543 [Patent Document 2] Patent Publication No. 2018-89374 Summary of the Invention [Problem to be solved by the invention]
[0004] The cleaning tools described in the above patent documents are convenient because they can be wiped by moving the soles of the feet along the floor while standing. Also, some of the tools have triangular tips so that the apex of the tips can reach corners and wall edges of rooms, making it easy to wipe away dust from corners (see Patent Document 2, Figures 15 and 16). However, when the triangular configuration is used to clean corners several times, the apex becomes deformed and worn out, causing the apex to become unable to reach the corner of the floor. An object of the present invention is to provide a cleaning sheet that can easily clean corners by suppressing deformation of the tip portion of the cleaning sheet. [Means for solving the problem]
[0005] The present invention, which solves the above problems, has the following configuration. (1) A cleaning sheet that is detachably attached to the bottom of footwear and is interposed between a floor surface and the bottom of the footwear, A wiping portion capable of contacting a floor surface; An adhesive portion disposed on the footwear side of the wiping portion and attached to a bottom surface of the footwear; a core material that is disposed on the footwear side at an end of the wiping portion at a position where a tip of the wiping portion protrudes from the footwear and has a higher rigidity than the wiping portion; A cleaning sheet having (2) The cleaning sheet according to (1) above, wherein the tip of the core material is formed at a right angle or an acute angle. (3) The cleaning sheet according to (1) or (2) above, wherein the tip portion of the core material is bent in the opposite direction to the footwear. Effect of the Invention
[0006] According to the invention described in claim 1, the cleaning sheet can be attached to the bottom of the footwear in a detachable manner, so that it can be attached when needed and removed from the bottom of the footwear when not needed. Since it is interposed between the bottom of the footwear and the floor surface, for example, the wiping part can come into contact with the floor and clean it by simply walking on the floor while wearing the footwear with the cleaning sheet attached. Since it can be attached to the bottom of the footwear by the adhesive part, it is easy to attach and remove. The core material, which is more rigid than the wiping part, prevents the edge of the wiping part from becoming worn, so that corners of the floor can be cleaned for a longer period of time. According to the invention described in claim 2, by forming the tip of the core material into an acute angle or right angle, cleaning of floor corners becomes easy. According to the invention as set forth in claim 3, by bending the core material towards the floor, durability against sagging can be further increased, and the mat can be used for a longer period of time. [Brief description of the drawings]
[0007] [Figure 1] 1 is an overall perspective view showing a configuration of the present invention; [Diagram 2] FIG. 2 is an overall perspective view showing the state in which the device is attached to the bottom surface of footwear. [Diagram 3] 3 is a cross-sectional view taken along the line AA in FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, in which: Fig. 1 is an overall perspective view showing a state immediately before a cleaning sheet of the present invention is attached to the bottom surface of a slipper, which is an article of footwear. The cleaning sheet 1 has a wiping part 2, a core material 3, and an adhesive part 4. The cleaning sheet 1 of this embodiment is attached to the bottom surface of slippers 5, which is a type of footwear. The wiping part 2 is composed of a wiping member formed in a shape that is approximately along the shape of the bottom surface of the slippers 5 to which the cleaning sheet 1 is attached. The wiping member is composed of, for example, a fiber assembly. Examples of the fiber assembly include paper, nonwoven fabric, felt, woven fabric, and knitted fabric. The fibers that compose the fiber assembly are thin, flexible, and cohesive string-like materials obtained by naturally stretching animal hair, leather, plants, etc., or by artificially stretching them, and include, for example, chemical fibers.
[0009] Such wiping members may be impregnated with a chemical to improve the dust absorbing / wiping effect or the wax effect. As shown in Fig. 1 and Fig. 3, the wiping part 2 of this embodiment is configured to be attached to the front part of the bottom surface of the slipper 5 from the toe to the position corresponding to the arch of the foot. As shown in Fig. 1, the wiping part 2 is shaped like a rectangle whose width is the same as the width of the slipper. By making the tip 21 into such a shape, as shown in Fig. 2, the tip 21 forms a protruding part 210 that protrudes significantly outward from the bottom surface of the slipper 5. The protruding part 210 increases the wiping area and improves the wiping effect. The corners 211 of the protruding part 210 are either inside angles or right angles, so this part also makes it possible to wipe corners of the floor. However, if the material constituting the wiping part 2 is soft, there is a risk that a sufficient wiping effect will not be obtained.
[0010] The length of the wiping part 2 is approximately half the total length of the slippers 5. With this length, when the cleaning sheet of the present invention is attached to the slippers 5, the tip side of the slippers 5 is covered with the wiping part 2, and the part of the slippers 5 corresponding to the heels (the rear half) is exposed, and the heels of the slippers 5 directly contact the floor. With this configuration, the slippers 5 are less likely to slip on the floor when weight is placed on the heels. On the other hand, when wiping with the cleaning sheet 1 of the present invention, the heels are raised and the front half of the slipper sole is brought into contact with the floor, making wiping easy. The wiping section configured in this way has its underside in contact with the floor to wipe off dust and dirt on the floor. In particular, the tip of the wiping section can adequately wipe off dust and dirt that has accumulated in the corners between the floor and the wall.
[0011] The core material 3 is overlapped and attached to the tip of the upper surface of the wiping part 2. The shape of the tip 31 of the core material 3 is formed in a triangular shape along the shape of the wiping part 2, and the angle of the apex is formed in a right angle or an acute angle. The core material 3 is made of a material having higher rigidity than the material constituting the wiping part 2. For example, it is cardboard, a resin plate, a thin metal plate, etc. The tip of the core material 3 protrudes from the tip of the slipper 5 in the same manner as the wiping part 2, and the base end of the core material 3 is located at a position overlapping the bottom surface of the slipper 5. The position where the core material 3 of the wiping part 2 overlaps is deformed integrally with the core material 3, and has higher rigidity than the part where the core material 3 does not overlap. With this configuration, the core material 3, which has a higher rigidity than the material of the wiping part 2, makes it easier for the tip of the wiping part 2 to reach the back of the floor corners, and also suppresses deformation (sagging) of the wiping part 2 due to repeated use. Furthermore, by making the tip of the core material 3, i.e., the part protruding outward from the underside of the slipper 5, bent downward (towards the floor), the apex of the tip can come into point contact with the floor surface, making it easier to remove dust and dirt from floor corners, grooves and other small areas.
[0012] The core material 3 may also be made of an elastic material. Making the core material of an elastic material increases the allowable range of deformation and improves the durability of the core material 3. In addition to cleaning small areas, when wiping a flat floor, the tip elastically deforms and flattens along the flat floor, allowing the tip to clean both corners and small areas as well as flat surfaces. An adhesive part 4 is provided on the upper surface of the wiping part 2. The adhesive part 4 is composed of an adhesive layer 42 and a cover sheet 41 attached to the upper side thereof. The adhesive layer 42 is arranged along the approximate center line from the base end to the tip end of the wiping part 2, and covers the base end 32 of the core material 3 at the tip end. The adhesive part 4 may be provided on approximately the entire surface of the part 22 overlapping the bottom surface of the slipper 5, or may be provided on a part of the part as shown in FIG. 1. It is preferable that the adhesive part 4 is provided in an area including the core material 3. In other words, the adhesive part 4 has the function of attaching the wiping part 2 and the core material 3 to the bottom surface of the slipper 5. By attaching the core material 3 to the bottom surface of the slipper 5, the core material 3 is supported by the harder bottom material of the slipper 5, making it easier to push the core material 3 into the corner of the floor. The cover sheet 41 acts as a covering material to prevent the adhesive layer 42 of the adhesive part 4 from sticking to any part other than the bottom surface of the slipper 5 during transportation or storage. Just before sticking the cleaning sheet 1 to the bottom surface of the slipper 5, the cover sheet 41 is peeled off from the adhesive part 4 to expose the adhesive layer 42, which is then stuck to the bottom surface of the slipper 5.
[0013] FIG. 2 is an overall perspective view showing the cleaning sheet 1 attached to the bottom surface of a slipper 5. As shown in FIG. Even if the tip of wiping part 2 is rectangular in shape, if tip 31 of core material 3 is triangular, when tip 31 is inserted into a floor corner, wiping part 2 bends upward along the edge of tip 31 of core material 3 as shown by the imaginary line in Figure 3, and the tip of wiping part 2 becomes triangular in shape, making it possible to thoroughly clean the floor corner.
[0014] Fig. 3 is a cross-sectional view taken along the line AA in Fig. 2. As shown in the figure, the tip 31 of the core 3 is configured to be bent toward the floor (the side opposite to the slipper 5). By configuring it in this way, the tip can be inserted into a groove in the floorboard to easily remove dust and other debris that has accumulated in the groove. Moreover, as shown by imaginary lines, the wiping portion 2 may be further equipped with a fluffy wiping material 23 to enhance the wiping function. As another modification, the shape of the tip of the core material 3 may also be a rectangular portion 33. In this case, the interior angles of the two vertices 34a, 34b of the rectangle become right angles, and one of the two vertices can be used to clean a floor corner. At that time, the wiping part 2 bends along the shape of the tip of the core material 3 (rectangular portion 33), making it possible to clean the floor corner. In addition, the cleaning sheet of the present invention can be used as a disposable cleaning sheet that is discarded after use by constructing the wiping part 2 and the wiping material 23 from inexpensive nonwoven fabric, etc. By attaching it to slippers, the slippers themselves can become cleaning tools, so there is no need to prepare a separate cleaning tool such as a mop for wiping floors, and there is also no need for a place to store such cleaning tools.
[0015] By attaching the cleaning sheet 1 with the core material 3 to one of a pair of left and right slippers and attaching the cleaning sheet 1 without the core material 3 to the other slipper, the pair of cleaning sheets can be used in a different way, such as cleaning the corners of the floor with the cleaning sheet of one slipper and cleaning the floor surface other than the corners with the cleaning sheet of the other slipper. In such a case, as described above, since the sole of the slipper is exposed at the heel part, the weight is placed on the heel part of one slipper to push down, and the heel of the other slipper is lifted to clean the floor. By alternately performing such actions with the left and right feet, floor cleaning can be performed efficiently. As another modification, the shape of the tip portion of the wiping part 2 may not be rectangular, but may be triangular, protruding further toward the tip than the toe portion of the slipper 5, as shown by imaginary line 212 in Fig. 1. In this case, only the tip portion protrudes from the tip of the slipper 5. The tip of this triangular protrusion 21 is formed at a right angle or acute angle, so that the sharp tip of the wiping part 2 can reach the back of the floor corner. [Explanation of symbols]
