  Hereinafter, an embodiment of a tile cutting ruler according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1, a tile cutting ruler 1 according to this embodiment is a tile cutting ruler configured by connecting two sets of parallel links in a rectangular shape, and includes four corner portions 2, 2, 2. , 2 (of which the two adjacent corner portions 2 and 2 are adjacent to the first corner portions 2A and 2A and the remaining two adjacent corner portions 2 and 2 are the second corner portions 2B and 2B), respectively. Four second bar members 3, 3, 3, 3 provided between the corner portions 2, 2 are provided. In the present embodiment, these are made of plastic. However, these materials may be metals such as aluminum, iron, and stainless steel, or carbon.

  As shown in FIG. 2, the first corner portion 2 </ b> A includes a pair of first bar members 20, 20 whose end portions are rotatably connected by a connecting portion 24. Each first bar member 20 is a flat square member having a width larger than the thickness. Each first bar member 20 includes an insertion portion 21 that protrudes from an end opposite to the connecting portion 24. The insertion part 21 has a smaller thickness and width than the main body part of the first bar member 20.

  Each first bar member 20 includes a stepped portion 21 at the end on the connecting portion 24 side. One first bar member 20 includes a stepped portion 21 on the upper surface side. The other first bar member 20 includes a stepped portion 21 on the lower surface side. Thereby, a pair of 1st bar members 20 and 20 become uniform thickness in the state where the edge parts were piled up. That is, each of the upper surface and the lower surface of the pair of first bar members 20, 20 is the same surface (the same surface).

  Each first bar member 20 includes a hole 23 with a seat 23a at the end on the connecting portion 24 side. The connecting portion 24 mainly includes a bolt 25 that passes through each hole 23 that is concentric with the step portions 21 and 21 of the pair of first bar members 20 and 20 and a wing nut 26 that is screwed into the bolt 25. To do. The head 25a of the bolt 25 has a small thickness, and even if the head 25a is inserted into the seat 23a of the first bar member 20 and does not protrude from the upper surface of the first bar member 20, the protrusion amount is small. A washer 27 is inserted into the seat 23 a of the other first bar member 20 for contact with the wing nut 26.

  As shown in FIG. 3, the second corner portion 2B has basically the same configuration as the first corner portion 2A. The difference is the structure of the connecting portion 24. The connecting portion 24 of the second corner portion 2B has a main configuration of a pair of pins (convex pins 28 and concave pins 29) that are concavo-convexly fitted. Even if the flange portion of the convex pin 28 is inserted into the seat 23 a of the first bar member 20 and does not protrude from the upper surface of the first bar member 20, or protrudes, the amount of protrusion is small. Even if the flange portion of the concave pin 29 is inserted into the seat 23 a of the other first bar member 20 and does not protrude from the lower surface of the first bar member 20 or protrudes, the amount of protrusion is small.

  As shown in FIG. 4, the second bar member 3 is a flat square member having the same cross-sectional shape as the main body portion of the first bar member 20 and having a width larger than the thickness. The second bar member 3 has a hollow tube shape and has the same cross-sectional shape as the insertion portion of the first bar member 20. For this reason, the insertion part 21 of the 1st bar member 20 can be inserted in each edge part of the 2nd bar member 3. As shown in FIG.

  In a state where the first bar member 20 and the second bar member 3 are concavo-convexly fitted, the upper surface, the lower surface, the outer edge surface and the inner edge surface of the first bar member 20 and the second bar member 3 are the same surface (same surface) It becomes. For this reason, each of the upper surface and the lower surface of the tile cutting ruler 1 is the same surface (the same surface). Then, the tile cutting ruler 1 is formed by two first bar members 20 and 20 and the second bar member 3 on each side of the tile cutting ruler 1 which is a rectangle (a rectangle (concept that a rectangle includes a square)). Each link is configured. Further, on each side, the outer edges of the two first bar members 20 and 20 and the second bar member 3 are in a straight line, and constitute a ruler portion as the tile cutting ruler 1.

  A plurality of types of second bar members 3 having different lengths are prepared (FIGS. 4A to 4C are a part of them). Since the length of the first bar member 2 is fixed, a plurality of types of second bar members 3 having different lengths are prepared according to the tile size and joint width excluding this length. Thereby, if the 2nd bar member 3 is replaced | exchanged, the multiple types of ruler 1 for tile cutting from which the length (length of one side) of a ruler part differs can be comprised.

  The tile cutting ruler 1 according to the present embodiment is configured as described above. Next, a method for drawing a cutting line on a tile using the tile cutting ruler 1 will be described.

  FIG. 5 provides joints between the tiles T and T and between the wall W and the tile T. In a mode in which the wall W is inclined with respect to the construction line of the tile T, the tile T to be constructed near the wall is arranged. A case where a cutting line is drawn on the tile T using the tile cutting ruler 1 in order to cut in accordance with the shape of the wall is shown.

  In this case, as the ruler 1 for cutting the tile, the second bar member 3 is selected in which the length of the ruler is equal to the joint joint dimension (actual dimension of the tile T + joint width H) plus the joint width H. Use what you did. First, i) The tile t to be cut in accordance with the shape of the wall is overlaid on the already applied tile T adjacent to the construction site. ii) Next, the tile cutting ruler 1 is changed in accordance with the inclination angle of the wall W, and the thumbscrew 26 is tightened to fix it at that angle. iii) Next, a link on one side of the tile cutting ruler 1 having the two first corner portions 2A and 2A, that is, a link on the one side having the protruding portion of the connecting portion 24 is set along the wall W. iv) The outer edge of the link opposite to this link, that is, the link on one side of the tile cutting ruler 1 having the two second corner portions 2B and 2B, that is, the link on one side that does not have the protruding portion of the connecting portion 24 Since the line coincides with the line to be cut of the tile t, a cutting line is drawn along the outer edge of the tile t (using a ruled line or a pen).

  As a result, the tile t is cut into two, but the one located outside the ruler 1 for cutting the tile matches the figure represented by the two-dot chain line near the wall in FIG. It becomes the tile T to be constructed. In this way, by simply replacing the second bar member 3, it is possible to draw a cutting line in consideration of the joint width in the tile size.

  FIG. 6 shows a mode in which joints are provided between the tiles T and T and between the wall W and the tile T, and the wall W is parallel to the construction line of the tile T. Also in this case, as the ruler 1 for cutting the tile, the second bar member 3 is selected in which the length of the ruler portion is the joint dimension (actual dimension of the tile T + joint width H) plus the joint width H. A cutting line can be drawn in the same procedure by using the above and fixing the angle of each corner portion 2 at a right angle.

  FIG. 7 shows a mode in which a joint is provided between the tiles T and T, but no joint is provided between the wall W and the tile T. In this case, as the tile cutting ruler 1, the same thing can be obtained by selecting the second bar member 3 in which the length of the ruler portion is the joint size (actual size of the tile T + joint width H). A cutting line can be drawn in the procedure.

  FIG. 8 shows an aspect in which each of the two walls W and W that are corners is inclined with respect to the construction line of the tile T. In this case, using one tile cutting ruler 1, first, as shown in FIG. 8A, a cutting line in relation to one wall W is drawn, and then as shown in FIG. A cutting line in relation to the other wall W is drawn. As a result, a cutting line at the corner can be drawn on the tile T. Note that two tile cutting rulers 1 and 1 may be used side by side to draw a cutting line all at once.

  FIG. 9 shows a tile cutting ruler 1 in which two sets of parallel links have different lengths. In short, if the distance from the wall W can be grasped, the cutting line of the tile T can be appropriately drawn. For this reason, the shape of the tile 1 is not particularly problematic. However, like the tile cutting ruler 1 shown in FIG. 9, a tile suitable for drawing a cutting line on a rectangular tile by using a rectangular shape in which the lengths of the links on the vertical and horizontal sides are different. It can be a cutting ruler.

  Further, according to the present embodiment, the tile cutting ruler 1 is configured such that the tiles T and t overlap with each other by overlapping the tile t to be cut on the existing tile T and performing the work. It is placed across the floor F where there is no T. For this reason, as shown in FIG. 10A, because of the large step, the tile cutting ruler 1 may be inclined during the operation of drawing the cutting line, and the cutting line may not be drawn appropriately. This fear becomes conspicuous when there are few portions of the tile cutting ruler 1 to be placed at the place where the tiles T and t overlap. However, according to the tile cutting ruler 1 according to the present embodiment, as shown in FIG. 5B, the protruding portion of the connecting portion 24 (the screw portion of the bolt 25) serves as a step eliminating means (height adjusting means). The tile cutting ruler 1 can be maintained in an appropriate posture, and thereby a cutting line can be drawn stably.

  In the case where it is preferable to have only one protrusion, as shown in FIG. 11A, the direction of one connecting portion 24 may be reversed upside down. When it is preferable that there is no protrusion, the tile cutting ruler 1 is turned over and used as shown in FIG. 5B, or both connecting portions 24 are turned upside down. Or when a protrusion part is unnecessary, it can also replace | exchange for the connection part 24 of the 2nd corner part 2B.

  Furthermore, by using a bolt 25 having a general head 25a as the bolt 25, the protruding amount of the protruding portion can be changed in two stages as shown in FIGS. Further, as shown in FIG. 3C, the tip of the wing nut 26 is attached to the floor, and the amount of protrusion of the protrusion is changed in multiple stages by changing the screwing amount of the wing nut 26. Can do.

  In addition, according to the tile cutting ruler 1 according to the present embodiment, a plurality of types of second bar members 3 are required, but the corner portion 2 and the second bar member 3 are separated and the corner portion 2 is separated. Can be stretched straight and stored compactly.

  The tile cutting ruler according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

  In the above embodiment, as means for connecting the corner portion 2 and the second bar member 3, the insertion portion 21 is provided in the corner portion 2, and the insertion portion 21 is inserted into the second bar member 3. A concave / convex fitting for providing a concave portion is employed. However, the present invention is not limited to this. For example, conversely, the insertion portion may be provided in the second bar member and the recess may be provided in the corner portion. Alternatively, an insertion portion may be provided in one first bar member of the corner portion, a recess portion may be provided in the other first bar member, a recess portion may be provided in one end portion of the second bar member, and an insertion portion may be provided in the other end portion. Good. Further, the connecting means between the corner portion and the second bar member is not limited to the concave-convex fitting, and various known methods can be adopted as long as the ruler portion can be formed on the outer edge of the link. .

  Moreover, in the said embodiment, the outer edge of a link is used as a ruler part. However, the present invention is not limited to this. For example, the inner edge of the link may be a ruler part.

  Moreover, in the said embodiment, multiple types of 2nd bar members from which length differs are provided. The difference in length means that a bar member having a common length is combined with various spacer members (length adjusting members) having different lengths, and the bar member and the spacer member constitute the second bar member. Is included.

  In the above embodiment, a plurality of types of second bar members are prepared in consideration of the difference in joint width in addition to the tile size. However, the present invention is not limited to this. For example, if the joint width is determined for each tile size, the second bar member may be prepared in a type that considers only the tile size.

  Moreover, in the said embodiment, the process of superimposing the tile t which is going to cut | disconnect in accordance with the shape of a wall on the already enforced tile T adjacent to the construction location is performed. However, the present invention is not limited to this. For example, a part adjacent to the construction part on the wall may be left unfinished, and a tile t to be cut may be placed here to draw a cutting line. In this case, the step is the thickness of one tile.

  Moreover, in the said embodiment, the connection part 24 which has a protrusion part is provided in the two corner parts 2 and 2. As shown in FIG. That is, two first corner portions 2A are used. However, the present invention is not limited to this. There may be one connecting portion 24 having a protruding portion. That is, only one first corner portion 2A may be used.

  In the above embodiment, the thumbscrew 26 is used as a fixing means for the connecting portion 24. However, the present invention is not limited to this. For example, a pipe screw may be used. In this case, it is preferable that the tip of the screw portion of the bolt 25 is covered with a pipe screw. In order to prevent cement from adhering to the tip of the screw part and screwing smoothly, the pipe screw can be used as a step elimination means (height adjustment means) that can change the protrusion amount of the protrusion in multiple stages. This is because it can be used.

  In addition, the term specifying the shape, part or state such as “rectangular shape”, “rectangular shape”, “end”, “parallel”, “same surface (same surface)” is used in the present invention. It also includes the concept of “abbreviation” meaning close or similar.
