Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an end fitting reference tool which is used as a reference for dimensioning by applying an end face of a scale when dimensioning a tatami mat.

[0002]

2. Description of the Related Art The dimensions of a tatami mat are measured using a special scale (so-called sash) to measure the size of the room.
For example, in the case of six tatami mats, a method is adopted in which dimensions are allocated so that six tatami mats fit completely in the whole and the dimensions of each tatami mat are determined. Even if the room to be dimensioned is designed to be square, there is a slight deviation in the squareness, so a squareness standard is used for dimensioning.

FIG. 8 shows an example of the case where dimensions are measured using an optical right-angle standard A for projecting a laser beam in two directions at right angles. Here, the laser beam Y with respect to the threshold B ₁ is and sets the reference device A so as to pass through the position to keep the distance 90cm from the threshold B ₁ parallel and threshold B _1, the position (b) of FIG. Sill B using a scale-up S
Measure the distance from ₂ to the laser beam Y. If the measured value is 179 cm, the width of one end of the tatami is determined to be 89 cm by subtracting the tatami width of 90 cm.

[0004] Next, (b), (c), the position at each measure the distance from the threshold B ₂ to the laser beam Y tatami other side of the length of (d), tatami other end of the width (the The width to the other end is also 90 cm) and the length of both sides of the tatami mat is determined. After that, the scale S is rotated by 90 °, and the distances from the thresholds B ₃ and B ₄ to the laser beam X are obtained at each of the positions (e) to (f), and the length of the tatami mat is 180 cm and the width of the tatami mat is 90
cm, and determine the width of both ends of the tatami mat and the length of both sides of the tatami mat.

[0005] In the dimensioning of the tatami mats performed in this manner, the scale S is set between the sills at the opposing positions, the scale at the position where the laser beam passes is read, and the distance from the sill to which the scale edge is applied is examined. In addition, although the scale edge may be applied to a tatami mat or the like, in the present invention, for convenience of explanation, all the portions that are the reference for dimensioning are regarded as thresholds and expressed as thresholds.

[0006]

When a new tatami mat is replaced with an old tatami mat, the old tatami mat is often set up and the dimensions are measured. If the tatami mats are laid, the scale cannot be set stably between the sills whose upper surface is at almost the same height as the surface of the tatami mats. When the surface position is higher than the threshold, it is impossible to set the scale itself.

However, when the tatami is raised and dimensioned, it is necessary to move furniture and furniture in the room to a place where they do not interfere. If you can't afford to move furniture or removed tatami to another room, you will have to move it many times in the same room, increasing wasteful work. In addition, when moving furniture or the like, the set reference device is moved and the standard is out of order.

[0008] Therefore, an object of the present invention is to enable new dimensions to be taken without removing an old tatami mat.

[0009]

In order to solve the above problems, the present applicant has invented the following end contact reference tool. The end contact reference tool is provided with an upper surface of a sill or an abutment surface on a tatami mat above a plate-shaped insertion portion inserted between the edge of the tatami and the sill,
Further, a scale-end receiving portion standing on a sill is provided continuously above the insertion portion, and the positions of the front surface of the receiving portion and the rear surface of the insertion portion are aligned on the same line.

[0010] It is preferable that the reference tool is provided with a needle hole penetrating vertically on the back side of the receiving portion. It is also preferable to provide a vertical collation line on the front surface of the receiving portion.

[0011]

[Operation] The insertion part is inserted between the edge of the tatami mat and the sill, and the receiving surface is put on the upper surface of the sill or on the tatami mat, and the receiving part is set up on the sill. At this time, the front surface of the receiving portion is flush with the side surface of the sill where the back surface of the insertion portion is in contact. Therefore, it is possible to create a state equivalent to when the scale is passed between the sills by attaching the two reference tools to the sills on both sides facing each other and applying the scale end to the front surface of the receiving portion of each reference tool. , Accurate measurement can be performed without removing the tatami mat.

In the case of a device having a needle hole, a reference tool can be temporarily fixed on a sill with a stopper having a stop needle.
When the temporary fixing is performed, even if the gap between the sill and the tatami is large, the reference tool does not fluctuate, and the measurement can be stably performed.

In the case where the reference line is provided, the position of the right angle reference device can be changed or the position can be corrected by using the end contact reference device. This will be described later with an example.

[0014]

FIG. 1 shows an embodiment of an end contact reference tool according to the present invention. The end contact reference tool 1 is configured to insert a plate-like insertion portion 2 to be pressed between the edge of the tatami mat C and the sill B, an abutment surface 3 projecting rearward at a right angle from an upper end of the insertion portion 2, and a front surface 4a. Receiving part 4 aligned on the extension of back surface 2a of part 2
And comprising.

In order to improve the insertability, it is preferable that the lower end side of the insertion portion 2 is tapered as shown in the figure, and the edge of the tapered portion is chamfered.

The end fitting reference tool 1 is configured to measure the size of the sill on both sides by contacting the end of the sizing scale with the front surface of the receiving portion. Therefore, at least two tatami mats are required for dimensioning.

In the reference tool 1 shown in FIG. 1, two stainless steel plates (about 1 mm thick) bent in a right angle L shape are overlapped, and after spot welding, the insertion portion 2 is edged. It is made by folding a strip-shaped metal plate into two and bending one end and the other end by 90 ° in opposite directions (see FIG. 2), or as shown in FIG. 4 may be formed of a square block, the insertion portion 2 may be joined to the lower part of the front surface of the square block, and the lower surface of the square block may serve as the contact surface 3, or may have a shape as described later. The point is that it has an insertion portion 2, a contact surface 3, and a receiving portion 4, and a front surface 4 of the receiving portion.
It is sufficient that a is placed on the same line as the back surface 2a of the insertion portion. The material is preferably metal in terms of durability, but may be plastic.

The size here is about 3 cm in width and about 7 cm in height. The length (height) of the insertion portion 2 is shorter than the sill height from the floorboard.

If the threshold is a siding, the depth dimension d of the contact surface 3 must be smaller than the width of the siding (sill B in the figure) as shown in FIG. 4 or FIG. The reference tool 1 having a small depth dimension of the contact surface 3
If there is a large gap between the tatami mat and the sill, there is a risk of shaking after installation. Therefore, as shown in FIGS. If the needle hole 5 is a deep hole as shown in FIG.
The wobble of the reference tool 1 can be stopped by the needle passed through the hole. The shallow needle hole 5 as shown in FIG. 5 pierces the threshold B by passing the push pin E through the hole,
The reference tool 1 can be temporarily fixed by pressing the top surface of the needle hole forming portion with the head of the push pin.

FIG. 6 shows a collation line 6 on the end contact reference tool 1 of FIG.
Is added. The collation line 6 is provided vertically on the front surface (preferably, the center in the width direction) of the receiving portion 4. This collation line 6 can also be adopted as a reference tool of another form.

An example of the use of the end contact reference tool having the collation line 6 will be described below. Now, in FIG.
Is referred to as laser beam Y has finished set so as to be parallel with the threshold B _1. At this stage, the fiducials are attached to the positions I to IV in FIG. 8, and the fiducials are positioned so that the laser beam hits the collation line.

In this way, when it is desired to shift the position of the right angle reference device A, or when the reference device is unexpectedly moved, the reference device can be correctly positioned based on the reference line of the reference device at the positions I to IV. it can. For example, if the right-angle reference device A is left at the position shown in the figure and the measurement at the position (f) or (h) is performed at a position slightly deviated from the reference device (a position that does not cause interference with the reference device). Exact dimensions are not guaranteed.

Therefore, the right angle reference A is shifted in the Y direction when measuring at the position (h) and in the X direction when measuring at the position (f). At this time, if the direction of the reference device A changes, the dimensioning will be out of order. Therefore, when the reference device A is moved in the X direction, it is checked whether or not the laser beam X has deviated from the reference line of the reference device at the positions I and II. . Then, the direction of the reference device is corrected so that the laser beam, which has not been shifted, hits the collation line again. Similarly, when the reference device A is moved in the Y-axis direction, the laser beam Y can be kept on the initially set line. In addition, if the laser beams X and Y are aligned with the collation line of the projection destination with reference to the collation lines of the fiducials at the respective positions I to IV, even if the right angle standard device moves after setting, it can be reset. This eliminates the need to start measuring again from the beginning.

FIG. 7 shows a reference tool in which the contact surface 3 is provided at the front portion so as to contact the upper surface of the tatami mat C. In this way, the object of the invention is achieved even with a structure in which the contact surface 3 is placed on a tatami mat and maintains the set state. In addition, the contact surface 3 may use both the one placed on the threshold and the one placed on the tatami mat. It is also effective to provide a needle hole on the contact surface placed on the tatami mat so that the contact surface can be temporarily fixed to the tatami mat with a push pin or the like, or to add the above-mentioned collation line to this type of reference tool. That is.

[0025]

As described above, when the end fitting reference tool of the present invention is used, a reference surface to which the end of the dimensioning scale is applied can be created on the threshold, so that there is no need to raise the tatami mats.
The sizing of tatami mats can be simplified and speeded up.

[0026] Further, by proceeding with the tatami mats being spread, the number of times of moving furniture and the like is reduced, so that the set right angle reference device is less likely to be erroneously moved.
Work loss due to re-measuring is also reduced.

Since the end contact reference tool provided with the needle hole can be temporarily fixed, even if the area of the contact surface is reduced in consideration of attachment to the tatami mat, stable measurement can be performed.

In the case where the collation line is provided on the front face of the receiving portion, the right-angle reference can be moved without causing the deviation of the right-angle reference, or the deviation of the right-angle reference caused by an unexpected movement of the reference can be corrected. Can help improve the efficiency of work.
