Description

  The present invention relates to a sponge used for wallpaper construction. In particular, the present invention relates to a sponge for interior construction that can be used for wiping off glue remaining on the surface of wallpaper when it is constructed, or for sanding in a narrow wall or a wall base that is curved rather than flat.

  When performing interior construction such as wallpaper construction, the paste applied to the back of the wallpaper is being applied to the wallpaper surface of the joint part, the wallpaper surface of the boundary between the ceiling and the wall, surrounding edges, baseboards, etc. It will stick to. If the adhesive is left unattended, it may cause stains and discoloration, so the wallpaper operator puts a sponge soaked in water and puts it on the wallpaper surface, surrounding edges, baseboard, etc. When the work is completed, it is carefully checked whether there is any remaining adhesive remaining, and if there is any remaining wipe, it is carefully wiped off with a sponge or rag. Also, the sponge and dust cloth used for wiping off the glue are frequently washed to maintain the wiping ability of the glue.

  In the interior construction industry, rectangular parallelepiped sponges having a predetermined size and long sponges are sold in catalogs, and if they are long sponges, construction workers cut them into arbitrary lengths and use them.

  Moreover, various cleaning sponges have been proposed and known, although not for interior construction. For example, a body sponge made of a soft sponge, characterized in that a large number of slits are engraved at a predetermined interval and depth in the left and right and / or length and width on at least a part of the surface in contact with human skin. ing. (Patent Document 1) Nylon scrubbing widely used for washing dishes, bathrooms and toilets, car washing, bathing, etc., sponge scrubbing foamed with synthetic resin, and polyurethane with one area layer It is also known that a surface of a material or the like and a portion subjected to a polishing process are appropriately finely divided and die-cut, cut or scored at an appropriate depth. (Patent Document 2)

  Furthermore, a cleaner comprising a sponge body having a predetermined thickness and width, wherein the sponge body is formed with a cut in the width direction from the outer surface to the inside at a substantially center in the thickness direction. (Patent Document 3) or a cleaning sponge, characterized in that a block-like sponge body and a notch portion formed on a pair of mutually opposing side surfaces of the sponge body toward the center of the sponge body are provided (Patent Document 4) is also known.

  In the case of a simple rectangular sponge, there is a problem that it is difficult to use at the beginning of the first use because it is not familiar with the hand. Also, even if you try to wipe off the glue adhered on the flat sponge surface, the glue will adhere to the flat sponge surface and the glue will accumulate more and more. The number of times of rubbing is increased, and it takes time and effort to frequently clean the sponge and remove the glue adhering to the surface of the sponge. In order to clean the sponge, it is once lowered from the stepladder or the like and washed with a cleaning bucket, so that the stepladder rises and falls and places a burden on the construction worker.

In addition, when a large number of slits are provided on the sponge surface as in Patent Document 1 and Patent Document 2, the glue used for wallpaper construction has a high viscosity, and a detergent or the like is not particularly used to wipe off the glue. In order to wipe off the sponge just by immersing it in the sponge, the sponge will be deformed by frictional force. The sponge may be broken into small blocks by the slit, and the sponge should be avoided from the bottom of the slit. Many of them were not durable and could not be used repeatedly.

  In order to solve the above-mentioned problems, Claim 1 of the present invention is a rectangular parallelepiped interior construction sponge, wherein at least two slits are provided in each of a pair of opposing wiping surfaces, and the slits are opened. A second slit is provided in each of a pair of opposing surfaces of the sponge in a direction orthogonal to the direction in which the slit is provided.

  According to a second aspect of the present invention, the slit is an angle perpendicular to the wiping surface of the sponge, or an angle at which the slit is positioned on the end side of the sponge as the slit is in the sponge, or the slit is in the sponge. Accordingly, the angle is set on the center side of the sponge.

  A third aspect of the present invention is characterized in that at least one of the depths of the slits arranged on the wiping surface is different from the depths of the other slits.

According to a fourth aspect of the present invention, the wiping surface of one of the pair of wiping surfaces is wrapped around a sponge so as to be covered with the polishing paper for interior, and the ends of the polishing paper for interior are fitted into the second slits, respectively. It is characterized by being able to install abrasive paper for use.

  Since the sponge for interior construction of the present invention is provided with at least two slits on the wiping surface, by wiping off the part with glue on the wiping surface, the slit part is deformed so that the glue enters the slit, And since it wipes off so that it may be scraped off by the corner | angular part of the sponge which comprises a slit, the removal of glue can be performed efficiently.

And the second slit can be used to set the polishing paper for interior, so that the sponge is also deformed along the part where the sander is hung by deforming the sponge in a narrow area where a curved surface or a normal sanding tool cannot enter. Polishing work is possible.

It is a figure explaining the sponge for interior construction of this invention, (a) The figure of the state seen from the front, (b) The figure of the state seen from the side, (c) The figure of the state seen from the plane. It is a figure explaining the state which wipes off glue with interior construction sponge. It is a figure explaining the state which wound the sheet for wiping around the sponge for interior construction. It is a figure explaining the state which provided the slit which attached the angle. It is a figure explaining the state which changed the depth of the slit provided in the wiping surface. It is a figure explaining installing the abrasive paper for interiors in the 2nd slit.

  An example of an embodiment of the present invention is shown in FIG. FIG. 1 (a) shows the interior construction sponge of the present invention as seen from the front, FIG. 1 (b) shows it as seen from the side, and FIG. 1 (c) shows it as seen from the plane.

  As shown in FIG. 1, the sponge 1 is provided with two slits 2 on the wiping surfaces 1a and 1b. Then, both ends of the slit 2 are opened on the respective surfaces of the sponge 1, and second slits 3 are respectively provided in opposite directions on which the slit 2 is opened in a direction perpendicular to the slit 2. .

An example of specific dimensions of the present invention will be described. The sponge 1 is a rectangular parallelepiped having a length of 80 mm, a width of 80 mm and a length of 120 mm, and the slit 2 is provided with a slit 2 at a position of 20 mm from the center of the wiping surfaces 1a and 1b. The width of the slit 2 is about 1 to 3 mm and the depth is about 15 mm. As the sponge, a sponge having a hardness of about 10 ± 3 Kgf and a density of about 18 ± 2 Kg / m ³ is preferable. The above dimensions and numerical values are examples, and are not numerical values that limit the present invention. Further, a part or all of the corners of the rectangular parallelepiped may be chamfered into a flat surface or a curved surface with a curvature.

  If the distance between the slit 2 and the end of the sponge 1 is short, the sponge 1 may be further broken from the slit 2 during the wiping operation, so the distance between the slit 2 and the end of the sponge 1 should be 10 mm or more. desirable. For example, if the dimensions are 15 mm and 17 mm, the cracks hardly occur even after repeated use, and the durability was high.

  Since the slit 2 is provided for the wiping surface 1, the slit 2 is easily deformed even when it is held in the hand, so that it is easy to become familiar with the hand. And even if it uses repeatedly, it does not tear further from the slit 2, and durability is also good.

  And, by providing two slits 2 on the wiping surfaces 1a and 1b, the paste removal work after the construction of the wallpaper having a width of about 90 cm attached to the peripheral edge is 1.5 to 1.5 for the sponge not provided with the slit 2. When two slits 2 are provided, when two slits are provided, 0.5 to 1 reciprocation, that is, when there is no slit 2, the sponge is moved three to four times to the left and right. In the present invention in which two slits 2 were provided, the glue could be removed by one or two movements.

  As shown in FIG. 2 (the second slit 3 is omitted in FIG. 2), for example, a deformed state in which the sponge 1 is applied to the peripheral edge and the sponge 1 is moved from right to left is shown. However, the sponge 1 provided with the slit 2 is slightly opened in the left slit 2 as compared to the sponge without the slit 2, and the right slit 2 has the right side of the slit 2 in the right slit 2. The sponge part is deformed to the right, and the slit 2 part is wider than the left slit 2 and is rubbed against the surrounding edge. Since the sponge 1 is moved from the left to the right while in contact with the edge, the wiped paste enters the slit 2, and a lot of paste is attached to the surface of the wiping surface 1a. Because they can be wiped off without becoming a state, it has become an ability to be effectively wipe glue than sponge without the slits 2.

  Further, since the glue enters the slit 2, the glue remaining on the surface of the wiping surface 1a of the sponge 1 is reduced, so that the number of times of use until the sponge 1 is washed can be increased. For example, in the case of the peripheral edge of about 90 cm as described above, if the sponge is not provided with the slit 2, it was necessary to clean the sponge 3 to 4 times, but the sponge 1 of the present invention. The cleaning after wiping about 5-6 times improved. The increase in the number of times also leads to a reduction in the number of times of going up and down the stepladder, which is an improvement in efficiency that is extremely appreciated by the operator.

Moreover, as shown in FIG. 3, it can also be used by wrapping the wiping sheet | seat 10 (cloth, a synthetic fiber sheet, etc.) around the sponge 1 of this invention.
Immediately after the construction of the wallpaper, since the glue is in a state of being adhered, the glue is wiped off only with the sponge 1 of the present invention containing water. However, there are places where the glue is still thinly spread in some places. In such a portion, the wiping sheet 10 is wound around the sponge 1 as shown in FIG. It is preferable to completely wipe away the thin remaining glue by pressing the wiping sheet 10 into a state where there is a slit even when the wiping sheet 10 is wound.

  In the case of wallpaper construction, when the glue sticks to the sponge 1, there will be a part that will be in a state of being thinly spread. Is going. By wrapping the wiping sheet 10 around the sponge 1 while pushing the wiping sheet 10 into the slit 2, if glue adheres to the wiping sheet 10, the wiping sheet 10 can be easily replaced and the wiping operation can be continued. It is also effective to wrap and use as shown in FIG.

  As shown in FIG. 4, the slit 2 may be an oblique slit with an angle. The embodiment shown in FIG. 4 (a) is a case where the slit 2 has an angle that is closer to the end of the sponge as it enters the inside of the sponge 1, and in FIG. The case where the angle is set so as to be closer to the center of the sponge as it enters the interior of FIG. When the angle θ of the slit 2 is decreased, the avoidance of the sponge 1 can be seen, so that the angle θ of the slit 2 is preferably 45 to 60 ° from the viewpoint of durability and wiping. If the slit 2 is provided in a state where the wiping surface is angled, one of the two slits 2 is in an acute angle with respect to the advancing direction. The wiping effect at the corner of the sponge 2 downstream in the traveling direction is also improved. Actually, the sponge 1 is moved to the left and right by the operator. Therefore, the wiping operation is performed with the wiping effect being improved in the slit 2 on one side for any movement, which is effective. It becomes.

  Further, as shown in FIG. 5, the depth of the two slits provided on the wiping surfaces 1a and 1b may be changed. This may be applied to the slit with the angle θ disclosed in FIG. By using the deep slit 2a and the slit 2b, the wiping sheet is firmly held by the deep slit 2a when the wiping sheet 10 described above is provided, and the wiping sheet is securely held. In addition, it improves the deformability of the sponge 1 on the deep slit 2a side, and the slit 2a opens during wiping, so that the glue wiped off can easily enter the inside of the slit 2a and the wiping property is improved. It is also possible to make it. In FIG. 4 and FIG. 5, the second slit 3 is not shown.

  Next, the second slit 3 will be described. The second slit 3 is a slit for attaching commercially available interior polishing paper. FIG. 6 illustrates a state in which the interior polishing paper 11 is attached. The surface of the wiping surface 1a is in a state where a sponge is visible, and the end of the interior polishing paper 11 is fitted in the second slit 3, respectively, and the second slit provided in the wiping surface 1b, the surface 1c, and the surface 1d. The surface below 3 is covered with the interior polishing paper 11.

The interior polishing paper 11 having a width of about 75 mm and a length of about 240 mm is generally sold for sanding, and is also sold in rolls.
The depth dimension of the second slit 3 in the surface 1c, the dimension of the surface 1c from the second slit 3 to the wiping surface 1b, the length dimension of the wiping surface 1b, the dimension of the surface 1d from the second slit 3 to the wiping surface 1b, The dimension obtained by adding the depth dimension of the second slit 3 on the surface 1 d may be the same as the length of the interior polishing paper 11 or slightly larger than the length of the interior polishing paper 11. The depth of the second slit 3 is desirably a dimension that is difficult to come off in order to fit the end portion of the interior polishing paper 11, and is desirably about 10 to 20 mm.

  In FIG. 6, although the dimension of the surface 1c from the 2nd slit 3 to the wiping surface 1b and the dimension of the surface 1d from the 2nd slit 3 to the wiping surface 1b are disclosed by the same figure, the dimension added above is disclosed. Is the same as the length of the interior polishing paper 11 or a slightly larger dimension than the length of the interior polishing paper 11, so that the dimensions need not be the same.

  Since the sponge 1 of the present invention is provided with the second slit 3 in the above-described configuration so that the interior polishing paper 11 can be installed, a curved portion, not a flat surface, a normal sanding tool is inserted. While the sponge 1 is deformed in such a part that is not present, it is possible to perform sanding along the curved surface or to perform sanding in a narrow part. By performing the sanding through the sponge 1, the sanding can be efficiently performed without excessively sanding only a specific portion.

Although the embodiment in which the wiping surfaces 1a and 1b are each provided with the two slits 2 has been described above, in the case of a larger sponge size, two or more slits 2 may be provided.
