Description

[Detailed Description of the Invention] This invention belongs to the technology of the structure of a ruler which is a measuring instrument,
Among these, the one that measures height, particularly the one that relates to a beveled feeler gauge that has a horizontally elongated triangular shape, is a feeler gauge that measures the height of a gap. Furthermore, it is based on technology for correcting irregularities on the surface of wall panels (hereinafter referred to as panels) of movable partitions.

A bevel feeler gauge is a measuring ruler with a perpendicular line hanging down from the long hypotenuse of a horizontally elongated triangular ruler toward the bottom, and ordinal scales are carved in order from 0 depending on the length of the perpendicular line. .

It is a type of feeler gauge that is a ruler that measures the gap between objects, but in the movable partition industry, this beveled feeler gauge is used to correct irregularities that occur on the front and back surfaces of panels during manufacturing. Use it. That is, tension strings with weights attached to both ends are stretched across the left and right (or lower E) edges of the panel to be inspected, and the height of the gap created between the tension strings and the panel board surface is measured. used for Push the bottom of the angled feeler gauge on the panel surface perpendicular to the tension threads, and read the scale when it touches the tension threads to determine the degree of unevenness of the panel surface.

However, the problem is that when inserting the bevel feeler gauge into the tension thread, you have to stop when it comes into contact with the tension thread, which often results in reading the value on the ruler with the tension thread lifted up. It was a win. The same effect can be obtained even if a metal wire such as a piano wire is used as the tension thread. In other words, the above-mentioned state of being held up remains unchanged.

The weight for tensioning the wire or thread only needs to be strong enough to tension the wire or thread, and it does not need to be so heavy that the wire or thread cannot be lifted easily. This is because the thread is likely to break and other troubles may occur during work.

Also, methods using metal rods or strips have not been adopted. This is because the metal itself tends to warp and become uneven, which causes many inconveniences in use and storage.

It should be noted that it is rare to use a large side measuring device that uses lenses or light beams to measure the unevenness of a panel.

In the movable partition industry, the measurement methods using tension threads, vias/wires and beveled feeler gauges are the most accurate.

In the field of movable partitions, this method is performed at several locations on one panel, such as the top, middle, and bottom, to determine the unevenness or bending of the panel, and then use a press machine to correct any panels that require correction. be. Therefore, accurately and quickly determining the unevenness of a panel is one of the most important issues when manufacturing a panel.

The present invention is a tension thread with a weight lowered (the same applies to piano wire, and the same applies hereinafter), which is considered to be the most convenient way to measure the unevenness of a panel.
The above-mentioned disadvantages that occur when using a bevel gap gauge while using the conventional method of using a bevel gap gauge,
This was done in an attempt to resolve the issue.

That is, the present invention is characterized in that a paragraph is provided for each scale on the oblique side of the beveled feeler gauge that comes into contact with the tension thread.
In the past, the operator's manual pressure was used to break the tension and lift up tension threads without restriction by holding the oblique side like inserting a wedge into a gap. It is possible to indicate accurately by restraint, and at the same time, work efficiency is significantly increased, making it possible to use it regardless of whether one is skilled or unskilled. Note that the material used in the present invention is one that is conventionally used for rulers, such as resin or metal, and any known material is used, regardless of whether it is transparent, translucent, or opaque.

In order to describe the present invention in more detail, the present invention will be described below with reference to the accompanying drawings. A conventional A-angle feeler gauge l is shown in FIG. That is, it is a small piece of an elongated triangular flat plate, hanging perpendicularly to the base 3 from the hypotenuse 2, lowering Ij4, and using the tip in front of the triangle as the starting point, 1 ma + length of perpendicular line 4 to the hypotenuse 2. ) The major scale 7 is carved (engraved) in ordinal numbers from small to large according to the difference in strawberries, and the space between the major scales 7 and 7 is further divided into 10 equal parts and the minor scales 8 are carved, and 9 is the handle. .

On the other hand, the beveled feeler gauge lO of the present invention is as shown in FIG. 3, and is basically the same as the beveled feeler gauge A shown in FIG. The difference is that paragraphs 11 are sequentially formed by cutting out each division (section) of the major scale 7 and minor scale 8, excluding 0, from the small number to the large number. be.

z The shape of paragraph 11 is not limited to the one with a step-like shape cut out in a horizontal line as shown in the enlarged diagram in Figure 5, but also the shape of paragraph a in Figure 6.
-yf The waveform shown in the figure may be used. As shown in the figure, paragraph 11 includes, for example, 5. At the position of the major scale 7 of Qmm and the minor scale 8 of 5°1 mm, respectively,
.

The height and length of vertical M4.4) are 5.0 m+n and 5.0 m+n.
While maintaining the length of 1 mm, a notch is made between 5.0 and 5.1 mm. The structure of the present invention is such that the height of the perpendicular line 4 of the scale portion is maintained at each division of the large and small scales, and the section is cut out.

In addition, in paragraph 11 cut out along a horizontal line in Figure 5,
They are not evenly spaced as shown in the diagram, but for example, the major scale 7 is 1 mm to 2 ml! 1 perpendicular line 4.4 interval by 2
cm, and also 2I! Perpendicular line of lff1~3mm 4.4
They may be spaced at uneven intervals, such as 3 am. This uneven spacing is caused by the wave-shaped paragraph 1 following the horizontal line seen in the Q and aS f diagrams in Figure 6.
1 can also be done.

The bevel gap gauge 10 of the present invention does not have to have a zero point at the tip, that is, it may have a shape with the tip cut off. It is also possible to make the measurement work easier by applying a different color to each case, applying a luminescent material, or attaching magnets to the three ends of the base.

Next, to describe the measurement procedure using the present invention, first, at the center of the front plate 15 of the panel 12, weights 14.14 are placed at both ends.
Place the tension threads 15 with
Tension between the two ends (see Figure 7).

If the top plate 15 of the panel 12 has irregularities, a gap 16 will be created between the panel 12 and the tension thread 15 (see FIG. 4).
If you place the bevel gauge IO in this gap 16, with its 0 point (tip) part first, and push it forward with the handle 9 gently facing the tension thread 15 at right angles and with the base 3g on the top plate 16, In the case of the example shown in Figure @5, for example, the height of the gap L is 5
．． 5+++ m, 5.5 m in paragraph 11
The part m passes through tension thread 15, but 5.6 of paragraph 11
The +t+m portion is pulled by the tension thread 15 and cannot pass through. Then, the worker (determining the Ill) reads the scale of the bevel gap gauge lO and determines that the hole of the gap 16 is 5.
．． 5 m tn In the waveform paragraph 11 in Fig. 6, there is a concave point 17, and the tension thread 15 can be locked at this point. When it is stopped by the thread 15, the bevel gap gauge 10 can be lifted up a little by X and the scale at the tension thread 15 can be read, and the workability is much improved compared to the conventional A bevel gap. Depending on the gauge l, as shown in FIG. 2, the height of the gap 16 is likely to be measured with the tension thread 15 lifted up, and it is difficult to ensure accurate reading of the scale. For this reason, different measurement values were reported at the same location depending on the person performing the measurement or each time the measurement was performed. In the present invention, such failures are not observed, and even beginners can measure numerical values as accurately as experts.

The present invention can be used not only to measure irregularities on the top plate 16 of the panel 12, but also to measure gaps, such as between connecting panels 12 and 12, or in the joint between a column and a panel 12. .
