Description

[Detailed Description of the Invention] This invention relates to a mold ruler used to cut into a carpet tile near a wall when laying the carpet tile on a floor surface.

Carpet tiles (hereinafter simply referred to as tiles), which are made by planting piles and lining the back side with a synthetic resin layer and cutting them into predetermined shapes and dimensions, are easier to store, transport, and install than rolled carpets. It has the advantages of being easy to apply, it is rich in design as patterns can be pasted on it, and it is economical as only the parts that are dirty or worn out need to be replaced. It is rapidly becoming popular.

Conventionally, in order to install such tiles next to a wall, as shown in FIG. After pasting the ... with adhesive, turn the first row of tiles T11 over to the joint position of T21 (Fig. 3A),
When placed against the wall, overlap point a with tile T21,
Mark the backing layer 2 corresponding to b with a cutter or writing utensil, cut it along the line connecting points a and b, and place the flooring between the tile T21 and the wall W again with the front side (pile 1 side) facing up. It is to be fitted onto G (Fig. 3B). FIG. 4 is a sectional view taken along the line of FIG. 3.

In this method, the tile to be cut T11
The tile T21 has sagged at the step formed by the already laid tile T21 and the base surface that has not been laid yet (see Figure 4).
At the overlapped part with 21, the piles overlap and move easily, making it difficult to accurately determine the cutting point. Cutting too short may leave a joint, or cutting too long may push up, which is undesirable. Moreover, in this method, if the wall surface is sloped, when the tile T11 is applied to the wall, it will shift from the joint of the tile T21, so it is difficult to accurately determine the cutting position in that case as well. Furthermore, the cutting work at positions such as pillars and entry/exit corners becomes more complicated, and it is difficult for even highly skilled workers to achieve a good finish. Furthermore, since the tiles are placed upside down against the wall, there is a restriction that it is not possible to apply glue to the floor base near the wall.

This invention solves the above-mentioned problems and creates a tile pattern that allows for easy, accurate and quick cutting, and is extremely effective for cutting into sloped walls and areas with protrusions. The purpose is to provide rules.

That is, in this invention, a measuring bar mounting part is formed in the center of the bar body and extends at right angles to the main body, and the measuring bar is placed on the measuring bar mounting part at right angles to the main body. and the measuring bar is slidably mounted on the measuring bar resting part through a space formed by the measuring bar guide part fixed on the main body and the measuring bar resting part. The gist of the rules is the rules.

Hereinafter, the embodiments shown in the drawings will be described in detail. FIG. 1 shows an embodiment of the present invention, and A, B, C, D, and E are respectively a perspective view, a front view, and
They are a top view, a side view, and a sectional view taken along the line X-X in Figure C. As shown in the figure, a measuring bar mounting portion 11 is formed in the center of the rod-shaped main body 10 and extends perpendicularly to the main body 10 . The shape and size of the rod-shaped main body 10 are not particularly limited, but it is preferable that the rod-shaped main body 10 can accurately abut against the edge of the tile, and a rectangular column-shaped one is especially suitable. It is important that the measuring bar mounting portion 11 extends at right angles to the main body.
This will be explained in detail later, but when cutting (cutting) the tile near the wall, it is located in front of the cutting position (second row).
This is to measure the distance from the edge of the tile to the wall, and find a point of symmetry on the tile with that edge as the border. A plate-shaped body, a rod-shaped body, etc. can be used for this measurement bar mounting part. In the embodiment shown in FIG. 1, a triangular prism is formed integrally with the main body with its top facing upward. A measuring bar 12 bent into a chevron shape at an appropriate angle from the center is placed on this measuring bar mounting portion.
Place. Therefore, the peak shape of this measurement bar matches well with the top and both slopes of the triangular prism of the mounting section, and it can be slid on the mounting section without wobbling from side to side. Of course, the combination of shapes is not limited to these shapes; for example, if a flat plate-shaped platform is used, grooves can be provided at desired positions on the platform, and the measurement bar can also be shaped like a flat plate. Even if a protruding line corresponding to the grooved line is provided on this, it can be slid in the same manner without wobbling. Alternatively, as shown in FIG. 1, it is also possible to provide a guide or a measuring bar to prevent vibration 16 along both side edges of the mounting portion, or these may be used in combination. The point is that the measuring bar should be able to move smoothly on the measuring bar mounting portion without wobbling or wobbling, and should be able to slide at right angles to the main body.

Further, it is convenient to form a measuring bar guide part 13 on the top surface of the main body between the measuring bar mounting part and the measuring bar guide part 13 having a space corresponding to the shape of the measuring bar and corresponding to the thickness of the measuring bar. By doing this, it is possible to suppress the shaking of the measuring bar, and also to hold the measuring bar when it is slid and pulled out toward the main body (FIG. 1).

The measuring bar 12 is provided with a scale starting from the end edge 17 on the measuring bar extending side of the main body when the rear end is placed against a stopper 15 provided at the rear end of the measuring bar mounting portion (first scale). figure). Although this scale may be provided at only one end of the measuring bar, it is preferable to provide it at both ends, since it can be applied to walls that are oblique in any direction. 14 is a bolt for fixing the guide portion.

The present invention is constructed as described above, and how to use it will now be explained. First, as shown in FIG. 2, a tile T21 is pasted from the center of the room toward the wall W to the front (second row) of the position where molding (cutting) is required near the wall. Next, the tile T11 to be cut along the wall is turned over and accurately stacked on top of this tile T21. And these tiles T11,
At the edge (joint) facing the wall of T12,
Place the mold ruler main body 10 so that the side edge 17 of the measuring bar mounting portion 11 is exactly aligned with the extended side edge 17 of the mold ruler body 10. Next, the measuring bar 12 is slid in the direction of the wall W to come into contact with the wall W, and the side edge 17 at this time is
Read the scale of the upper measuring bar 12 (point C in Figure 2), that is, the distance L from the wall W to the edge of the tile _T11 .
Then, the measurement bar 12 is returned to its original state, and with the rear end of the measurement bar 12 in contact with the stopper 15, the previous point c of the measurement bar is found on the tile T11. Thereafter, several cuts are made on the tile T11 in the same manner, the cut is made on a line connecting these cutting points, and the cut is inverted and fitted between the wall W and the tile T21.

As described above, with the molding ruler of the present invention, a cutting point on a tile can be determined by simply bringing the side edge of the main body into contact with the tile side edge and moving the measuring bar back and forth once.
Therefore, the mold-making work can be performed easily, accurately and quickly, and the finished appearance is also good. In addition, in the conventional method, the tile to be pasted on the wall is turned over and placed against the wall to find the cutting point, which has the restriction that it is not possible to glue on the base of that part in advance, but with the mold setting ruler of this invention, you can Gluing can be applied to the base of the product, simplifying the process of applying glue. In this case, it is more preferable to provide a geta on the bottom of the main body or to raise it from the base by passing a bolt through it, as this will prevent glue from adhering to the main body.
