Description

[Detailed Description of the Invention] The present invention relates to a tatami edge drop height adjustment device that cuts vinyl stacked on a polyethylene plate along the longitudinal center line to facilitate division.

Conventional adjustment tools were folded twice in the longitudinal direction and attached to the back edge of the tatami, regardless of the parquet on the four sides of the room, the height of the threshold, and the thickness of the tatami. The height of the threshold is high and low, and there are thick and thin straw tatami mats, so make sure the top surface of these parquets or sills and the top surface of the tatami mat located there are at the same height. It was inappropriate.

For example, the thickness of this adjuster is about 2 mm, so when folded twice, it becomes about 4 mm thick.

If the height of the sill is 6 cm, and the thickness of the tatami mat to which the adjustment tool is folded double is 6 cm and 2 mm, then this tatami will be 2 mm higher than the height of the sill. Become.

In such cases, if a single non-folding adjuster was used, it would be possible to create a 6cm thick tatami, the same as the height of the threshold, but it could not be used in a wide range of widths.

This proposal was devised to eliminate this drawback.
To explain this with drawings, as shown in Fig. 1, vinyl 2 is layered on a base 1 mainly made of polyethylene, and a cut groove 3 is provided on the longitudinal center line to divide only the vinyl 2. do.

Since the present invention is as described above, when using it, as shown in Figure 3, by pinching both sides with your fingertips and pulling them in opposite directions, the polyethylene plate 1 is soft, so it can be separated along the cut grooves 2 of the vinyl. It can be done. By attaching this separated piece to the back edge of the tatami mat, it can be used as a parquet on the four sides of a slightly lower room or on the top of the sill.
The top surface of the tatami mats located there can be made to the same height.

In addition, if the tatami is thin and there is a large difference in level from the parquet or threshold, you can fold the adjuster twice as before, and then stack the separate pieces and attach them to the back edge of the tatami to make it thicker. This eliminates the difference in height between the door and the sill, making it possible to make the top surface exactly the same height.

Therefore, the accuracy difference is twice that of the conventional one.

Note that since the vinyl cut groove 3 is in the longitudinal direction, it can be stored in rolls as in the past, and the tension will not change even if force is applied during work.

Note that the effect is the same even if the vinyl 2 is made into two sheets from the beginning in the longitudinal direction and is layered on the polyethylene plate 1.
