Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tile cutter adapter for cutting tiles used on the wall surface or floor surface of a building.

[0002]

[Prior Art]

 The tiles used on the walls and floors of buildings are generally square or rectangular, but the place where the tiles can be attached is not exactly a square shape, but is an integer multiple of the tiles used. In most cases, it is not the length or width. Therefore, in the corners and peripheral parts of the area to be attached, tiles cut according to the shape are used.

As a tool for cutting this type of tile, a stationary diamond cutter or a handy type cutter has been conventionally used. Among these, the diamond cutter is configured to rotate the cutter disk by a motor, while pressing the tile against the cutter disk while sliding the tile straight on the table surface to cut the tile. Further, the handy type cutter is configured to press the cutter disk against a fixed tile and move the cutter while cutting.

[0004]

[Problems to be solved by the device]

 The diamond cutter mentioned above is used when cutting tiles in a so-called on-site alignment.In that case, a guide surface parallel to the cutter disk is made on the table surface by a gauge, etc., and one side of the tile is pressed against it to slide. The tile is cut while making it. Therefore, the above-mentioned conventional diamond cutter can only perform cutting so that the cutting line becomes a line parallel to one side of the tile. When this is intentionally used for cutting at an angle, conventionally, a marking line is attached to the tile in advance, and the tile is manually pushed linearly so that the cutter disk is cut along the line. Since there is no mechanical guiding means, not only can it not be cut accurately, but tiles often break, resulting in large material loss and poor workability.

In addition, since the guide means can hardly be used in the handy type cutter, accurate linear cutting is difficult except when cutting small tiles, and particularly when cutting large tiles diagonally. Had a problem of poor workability due to frequent cutting mistakes even by skilled workers.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an adapter for tile cutters that can easily and accurately cut tiles at a predetermined angle.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this invention has a base part for fixing a tile cutter that cuts tiles by rotating a disk-shaped cutter disk, and a movable base that mounts and moves the tiles to be cut. The base part is provided with a positioning part for positioning and fixing the tile cutter and a guide part of the positioned tile cutter in a direction parallel to the cutter disk. Includes a guided part that moves by engaging with the guide part, a slit that projects the cutter disk to the upper surface side and extends in a direction parallel to the moving direction of the movable table, and a tile that is to be cut. And a holding mechanism for holding the same at a predetermined angle.

Further, in the present invention, as a holding mechanism, a holding mechanism including a holder for holding a tile by contacting a part of the tile and an indexing mechanism for appropriately setting an angle of the holder with respect to the slit is adopted. You can also do it.

[0009]

[Action]

 In the adapter of this invention, the tile cutter is positioned by the positioning portion to be fixed to the base portion, and the guide portion of the base portion is engaged with the guided portion of the movable base to thereby move the movable base to the base. Assemble to the department. In that state, the cutter disk projects from the slit to the upper surface of the movable table. On the other hand, the tile to be cut is held at a predetermined angle with respect to the slit, that is, with respect to the cutter disk by the holding mechanism provided on the movable table. Therefore, if the movable table is moved along the guide portion, , Tiles held at a fixed angle are moved in a direction parallel to the cutter disc, resulting in the tile being cut linearly at the held angle.

If a holder with an adjustable angle is provided and the tile is held by this holder, the cutting angle can be set arbitrarily.

[0011]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of an adapter 1 according to the present invention, and this adapter 1 is composed of a base 2 and a movable base 3. The base portion 2 has a positioning portion 5 for positioning and fixing the tile cutter 4 in a substantially central portion, and the positioning portion 5 is formed in a rectangular frame shape so that the tile cutter 4 can be fitted therein. An example of the tile cutter 4 is as shown in FIG. 2, in which a drive device 7 including a motor is arranged on the lower surface side of the table 6, and a part of the cutter disk 8 rotated by the drive device 7 is a table. A base 10 on which the driving device 7 and the like are placed protrudes from a slit 9 formed in the center of the table 6 to the upper surface side of the table 6, and is fitted into the positioning portion 5. A safety cover for covering a part of the cutter disk 8 and a water reservoir for supplying water to the cutter disk are omitted in the drawing.

The base 2 is further provided with a pair of rails 11 as guides. The rail 11 is for guiding the movable base 3, and is attached so as to be parallel to the cutter disk 8 of the tile cutter 4 fixed to the positioning portion 5.

The movable table 3 has a slit 13 formed in the central portion of the panel 12, a guided portion on the lower surface, and an index holding mechanism 14 on the upper surface. That is, the slit 13 is for causing a part of the cutter disk 8 to project to the upper surface side of the panel 12, and has substantially the same width as the slit 9 in the table 6 and extends over substantially the entire length of the panel 12. Has been formed. Further, the guided portion is constituted by a roller 15 rolling on the rail 11 as schematically shown in FIG. 3, and this roller 15 is a panel 12 with the cutter disk 8 fitted in the slit 13. Is attached to the lower surface of the panel 12 so as to move back and forth in a direction parallel to the cutter disk 8.

The index holding mechanism 14 indexes and holds the tile T with respect to the slit 13, that is, with respect to the cutter disc 8, and holds the corner portion of the tile T by fitting it. It has a holder 16, a position adjusting slider 17 for moving the holder 16 closer to or further from the slit 13, and an angle adjusting slider 18 for determining a cutting angle of the tile T. As shown in FIG. 1, the holder 16 is formed by forming receiving seats 19 each having a right angle and a different size in a portion of a predetermined plate material on the slit 13 side. The end portion of the holder 16 on the slit 13 side, in other words, each opening end of each receiving seat 19 on the slit 13 side is formed such that the line connecting these opening ends is a straight line. One side of the tile T can be abutted and held.

The position adjustment slider 17 is an elongated member rotatably attached near one end of the slit 13, and has a long hole 20 formed in the longitudinal direction thereof. The end edge of the holder 16 is slidably engaged with the position adjusting slider 17, and a fixing member, for example, a thumbscrew 21 inserted into the slot 20 penetrates the holder 16. By tightening the thumbscrew 21, the holder 16 is fixed at an arbitrary position of the position adjusting slider 17. Further, the angle adjusting slider 18 is mainly composed of an elongated hole 22 formed substantially parallel to the slit 13 at the end of the panel 12, and the elongated hole 20 of the position adjusting slider 17 intersects with the elongated hole 22. For example, a thumbscrew 23 is inserted as a fixing member at the intersection. Therefore, by loosening the thumbscrew 23, the thumbscrew 23 moves in both of the long holes 20 and 23 to rotate the position adjusting slider 17, and the angle of the seat 19 in the holder 16 attached thereto, That is, the angle of the tile T is set arbitrarily.

Next, the operation of the adapter 1 will be described. First, the tile cutter 4 is fitted in and fixed to the positioning part 5 of the base part 2. In that case, the tile cutter 4 is installed so that the cutter disk 8 is parallel to the rail 11. Then, the movable table 3 is placed over the base 2, and the roller 15 is placed on the rail 11. In this state, a part of the cutter disk 8 of the tile cutter 4 projects upward from the slit 13 of the panel 12. Then, the movable table 3 is moved (moved to the lower left side in FIG. 1) so that the cutter disk 8 protruding from the slit 13 is located on the side opposite to the fixed portion of the position adjustment slider 17, and one of the holders 16 thereof is moved. The corner portion of the tile T to be cut is fitted and held in the seat 19. In that case, if the holder 16 is moved to the left side of FIG. 1 along the position adjusting slider 17, the cutting position of the tile T is moved to the right by the holder 16 approaching the cutter disk 8 and vice versa. If the holder 16 is moved to the right side of FIG. 1, the holder 16 moves away from the cutter disk 8 and the cutting position of the tile T is shifted to the left. Further, in the example of FIG. 1, one side of each seat 19 is parallel to the position adjusting slider 17 and the other side is perpendicular to the position adjusting slider 17, so that each of the slots 20, By loosening the thumbscrew 23 at the intersection of 23 and setting the position adjusting slider 17 to 45 degrees with respect to the slit 13, the cutting angle of the tile T held by the seat 19 can be made 45 degrees. In this state, if one side of the tile T is abutted against the end of the holder 16 on the slit 13 side and held, the cutting line of the tile T becomes parallel to the one side. Therefore, by rotating the position adjustment slider 17, the tile T can be indexed at an arbitrary angle.

If the cutter disk 8 is rotated while the position and angle of the tile T are adjusted as described above, and the movable table 3 is moved along the rail 11 in that state, the tile T is cut. It is fed linearly into the disc 8 and cut at the adjusted position and at the indexed angle. In that case, since the tile T is sent to the cutter disk 8 by moving the movable base 3 with respect to the base portion 2, the movement is smooth, and the tile T is held by the holder 16. Therefore, there is no risk that the orientation with respect to the cutter disk 8 will change, and therefore the tile T can be cut accurately at the desired position and angle.

By the way, the adapter 1 of the present invention is a portable type that uses the existing tile cutter 4, and therefore the positioning portion 5 for fixing the tile cutter 4 is provided on the base portion 2. It suffices that the part 5 is one that matches the tile cutter to be used, and is not limited to the rectangular frame shape described above. It is possible to adopt various configurations such as the ones used as needed. The guide part and the guided part in this invention may be any one as long as they compensate for linear movement, and in addition to the rail 11 and the roller 15 described above, a combination of angle steel and caster, a guide rod and this. It is possible to use various conventionally known structures such as a combination with a sleeve slidably fitted to the above, a linear guideway with a built-in ball, and the like.

Further, in this invention, an indexing mechanism for indexing the cutting angle of the tile T may be provided as needed. That is, when used for cutting a large number of tiles at the same angle, the holding mechanism may be configured so that the tile holding angle is constant.

Although the adapter of the present invention is mainly used for cutting tiles, it can also be used for cutting other stone materials such as concrete. Therefore, in the present invention, the word "tile" refers to these stone materials. It includes.

[Effect of the device]

 As is clear from the above description, according to the present invention, it is extremely easy and accurate to cut a tile at an arbitrary angle, which was difficult in the past, and since the tile is not broken or the cut surface is not rough, work efficiency is improved. It is possible to improve the construction period and shorten the construction period. In addition to preventing unnecessary damage to the material, it is also possible to reuse the cut pieces, which greatly reduces the material cost and eventually the construction cost. It has excellent practical effects such as being able to achieve
