Description

  The present invention relates to a putty grinding tool for interior construction used in a base treatment as a pre-process for pasting wallpaper on a wall surface in interior construction.

  Background processing for smoothing the wall surface is performed before the wallpaper is pasted or replaced. In this base treatment, for example, putty is applied to joints or dents such as plasterboard, and the applied putty is used to grind the wall surface and ceiling surface smoothly with a grinding tool, and then wallpaper is applied.

  For grinding putty, a hand-held grinding tool is generally used. In addition, a hand-held operation sander and a cover member that covers the periphery of the sander in a state where the saddle surface of the sander is exposed, and dust generated from the sander is sucked from the inside of the cover member to a portable electric dust collector through a hose. In the dust collecting sander, the cover member is provided with a brush at the entire periphery of the lower end portion facing the surface to be polished, and a plurality of grooves are provided on the flange surface of the sander, and these grooves are sucked by the electric dust collector. There is also known a dust-absorbing type grinding tool such as a dust collecting sander (Patent Document 1), which forms a passage for airflow passing through the brush and entering the cover member. In the dust-absorbing type grinding tool, the grinding operation itself is performed manually.

  In the grinding operation for smoothing the putty-treated portion, every time grinding is performed with a hand-held tool, the fine powder of the putty that is ground is scattered, and the working environment is significantly lowered. Of course, when performing the grinding work, gloves, dust masks, dustproof glasses, etc. are used as appropriate.However, when grinding the ceiling, the operator is informed by the fine grinding powder falling from above. It was covered.

Although there is a dust-absorbing sander known from Patent Document 1 or the like, it is not often used in actual sites and is mostly carried out with hand-held tools that do not absorb dust. The reason why the dust-absorbing type sander is not used is as follows. The dust-absorbing sander is provided with a cover to absorb dust, but by sucking out the powder generated by grinding, it is covered with the cover, so that the force to press the sander tool itself against the wall is applied. As a result, moving the tool in the grinding operation is heavier than a tool that does not absorb dust, and one of the reasons is that the operator is in a state of applying a load. In addition, dust collection is performed by a dust collector, but the dust collector is also heavy, and the dust collector is configured so that an operator can wear it on a shoulder or waist belt, but it may be a long time work, Is loaded. In addition, when the work is performed with the dust collector placed on the floor, the grinding range is limited by the length of the hose, and the fact that the work efficiency is lowered is also a cause that is not used. In addition, many dust collectors are driven by motors, but they have heat during operation, and when the dust collector is placed on the shoulder, the dust collector itself becomes hot, which is also a burden on the operator. Was supposed to be applied. Therefore, there has been a demand for an improvement that reduces the amount of grinding powder without using a drive such as a dust collector.

  In order to solve the above-mentioned problem, claim 1 of the present invention is a putty grinding tool for interior construction used in a base treatment as a pre-process for pasting wallpaper on a wall surface, and a base portion of a sander provided with a handle The surface fastener is provided with a hook-and-loop fastener, and the hook-and-loop fastener has a hook-and-loop fastener that can be attached to and detached from the hook-and-loop fastener. It is characterized by adsorbing powder.

  According to a second aspect of the present invention, the brush is divided into two or more, and at least one of the divided brushes is removed so that the short side or the long side of the tool base portion and the corners at both ends thereof are covered with the brush. It is characterized by being in an undisturbed state.

According to a third aspect of the present invention, the brush is divided into two or more, and by removing at least one of the divided brushes, one corner of the base portion of the tool is not covered with the brush. It is characterized by.

Since the ground putty powder is adsorbed by the brush of the present invention, the putty powder falling can be reduced. And, the brush is divided into two or more, and by removing at least one, the putter powder is adsorbed with the attached brush, while the base of the sander is visible, such as the border of the wall or the boundary between the wall and the ceiling. Since the work can be performed near the boundary, the grinding work can be performed efficiently. Further, since the suction brush is lightweight and can be attached and detached, the load on the operator is greatly reduced.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view of a state in which a sander 1 of a hand-held tool is viewed from the handle portion 2 side. A surface fastener on which the abrasive paper can be freely attached and detached is provided on the entire surface opposite to the surface of the base portion 3 to which the handle portion 2 is attached. And the surface fastener 4 is provided in the circumference | surroundings of the handle part 2 in the surface by which the handle part 2 is attached. In general, the base part 3 has a general dimension of 70 mm in width or 75 mm and a length of 240 mm. Of course, various sizes of sanders for narrow spaces are provided, and they are selected and used at the time of construction depending on the preference of the operator.

  FIG. 2 illustrates a state where the dust absorbing brush 5 is attached to the sander 1. The dust-absorbing brush 5 has a hook-and-loop fastener 6 that is locked to a hook-and-loop fastener 4 provided on the base portion 3. The hook-and-loop fastener 6 is provided on both sides, and the brush 5 is temporarily removed from the state shown in FIG. Even if it is inverted 180 degrees, it is configured to be attached to the sander 1. Of course, the hook-and-loop fastener 6 may be provided only on one side. Although the present invention is not limited, the length of the brush is about 60 mm when the brush 5 is attached. Further, one of the brushes can be used as appropriate, such as a belt-like body or a cross-section having a circular or square shape. In the case of a belt-like body, the width is preferably set to a width of several millimeters to 10 mm. In the case of using a circular cross section or a quadrangular shape, for example, one piece may have a diameter or width of 0.02 mm, and about 40 g may be used. Of course, this dimension is not a numerical value that limits the present invention, and the longer the brush, the greater the amount of brush or the longer the length of the brush, the more the adsorption of putty powder in the grinding operation can be increased. Although the thickness and length are not limited numerical values, dimensions are disclosed as an example of the embodiment.

  The material used for the brush may be appropriately selected from resins that easily generate static electricity such as polyolefin resin such as polypropylene and polyethylene, and polyamides collectively called polyester and nylon, and that can easily absorb putty grinding powder. .

  In the present invention, the dust-absorbing brush 5 is not configured as a single body, but is divided into a plurality of brushes as a tool attached to the sander 1 and acting as a single brush. The purpose is to do. In order to make it easy to grind to the very boundary of the wall or ceiling when grinding the wall and the corner of the wall, the boundary between the wall and the baseboard, the boundary between the wall and the ceiling, etc. At least one of them is removed so that the grinding work can be performed in a state where the base portion 3 of the sander can be seen. An embodiment of dividing the brush 5 will be described with reference to the drawings.

  FIGS. 3 to 9 show examples of the division of the brush 5, and each will be described. The division example of FIG. 3 shows a state in which one long side of the base portion 3 of the sander 1 and corners located on both sides thereof are visible. This is an embodiment in which In the drawing, one brush 5a of the two divided brushes is attached and the other brush is removed.

  Since the long side of the base part 3 of the sander 1 and the corners located on both sides thereof are visible, the side on which the base part 3 is visible can be seen at the corner of the wall or the boundary between the ceiling and the wall, In addition, the grinding work can be performed as close as possible to the boundary between the wall and the skirting board. And although it is not the perimeter of circumference | surroundings, since the brush 5a is installed, it can grind, adsorb | sucking the cutting powder of the putty which comes out by grinding operation.

  The example of division of the brush 5 disclosed in FIG. 4 is substantially the same as that of FIG. With this division, both the attached brush 5a and the removed brush can have the same shape such as dimensions, so the cost of manufacturing and the shape of the brush are the same when used, so either size can be removed. Since it doesn't change, when it comes to a state where a lot of putty shavings are adsorbed, it is easy to use when replacing a new brush.

  However, as in the embodiment of FIG. 3, the end portion of the brush 5 a on the short side of the base portion 3 is positioned toward the corner portion on the side where the brush is not attached without setting the dividing position to the center of the handle portion 2. If it is configured, it is possible to absorb even more of the putty shavings that come out from the inner base part 3 of the brush in the grinding operation, so the same brush shape cannot be attached, but it can be more adsorbed It is effective.

  Whether to prioritize the adsorption performance or attach the same brush shape and prioritize the cost and usability of manufacturing the brush is a matter of design, and any of them may be adopted in the present invention. .

  The division example of the brush 5 disclosed in FIG. 5 is an embodiment in which one corner portion of the sander 1 and a part or almost one side of the short side and the long side are visible. In FIG. 5, the short side is seen about ½, but this may increase the range in which the short side is visible, or may extend the brush 5a further to the long side. In addition, the long side has a brush length such that the lower left corner in FIG. 5 is hidden, but this may also be a brush with a length such that the long side is more hidden.

  The division example of the brush 5 disclosed in FIG. 6 is a modification example of FIG. 5, and a state where one brush is removed, as shown in the figure, the corner portion of the sander 1 is one place, both the short side and the long side. These are embodiments in which one side is substantially visible. In the case of the division shown in FIG. 6, the divided brushes can have the same shape, and the size of the brush can be removed regardless of which one is removed because the shape is the same when used or the cost during production This is an embodiment that does not change.

  In the example of dividing the brush 5 disclosed in FIG. 7, the state in which one brush is removed is divided into a state in which the short side of the base portion 3 of the sander 1 and the corners on both sides thereof can be seen. It is a form. Since the short side of the base part 3 and the corners at both ends thereof are visible, the visible part can be ground to the border, such as near the wall, and putty powder ground with the attached brush 5a. Is adsorbed.

  In the divided example of the brush 5 disclosed in FIG. 8, the state in which one brush is removed is such that one corner of the long side is almost visible with the corner of the base portion 3 covered with the brush as shown in the figure. It is an embodiment that can be removed. Since all four corners of the brush 5a are covered, it is an embodiment that is easy to attract. When grinding a wall or the like, the brush 5a does not interfere with the grinding, with the surface fasteners 6 at the upper and lower corners of the long side of the base 3 in the visible state slightly peeled off. In this embodiment, stable grinding work and suction can be performed.

  The example of dividing the brush disclosed in FIG. 9 is the embodiment illustrated in FIG. 7, with the single brush removed, the short side of the base portion 3 of the sander 1 and the corners on both sides thereof can be seen. It is a modification of embodiment divided into a state. The long side of the base portion 3 is almost covered with the brush 5a, and since one short side, a part of the long side on the short side and two corners are visible, This is an embodiment in which adsorption to the brush 5a is easy.

  Moreover, in said embodiment, although the division | segmentation of the brush 5 has demonstrated and demonstrated the example of 2 division, a division | segmentation is not limited to 2 division. For example, the brush 5a in FIG. 4 can be divided into two at the center of the long side to form a substantially L-shaped brush, and four can be attached to cover the entire circumference of the base portion 3. In addition, one can be divided into three parts by using a brush that covers 1/2 shown in FIG. 4 and using two substantially L-shaped brushes (those that cover 1/4). Moreover, it is also possible to make it a brush which covers each side with two types of brushes with two brushes covering one short side and two brushes covering one long side.

  In the case of division, it is only necessary that the shape of the brush be the same as possible so that it does not become complicated during installation. The brush covering half of the base portion 3 may be a substantially U-shaped brush disclosed in FIG. Various division methods can be employed. Therefore, the division example illustrated in this embodiment is not limited.

Also, if putty powder is adsorbed on the brush and the amount of adsorbed increases, it can be easily replaced with another brush. It is possible to reduce grinding putty powder by replacing the brush with a new one that has not been used. As a result, the efficiency of cleaning during the base processing can be improved. Further, since the brush can be washed with water, the putty powder adhering to the brush can be washed and dried and used repeatedly.
