Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruler for scoring wood hole drilling positions in which scoring lines are inserted at standardized hole positions in wood.

[0002]

2. Description of the Related Art Wooden frame construction has mainly been composed of a frame construction method such as a tenon joint or a precut construction method, but in recent years, a metal fitting construction method of joining with a metal fitting has become popular. An example of this metal fitting method will be described. As shown in FIG. 13, one metal, for example, a pillar material 30, is attached with metal fittings 31 by several bolts, and the other wood, for example, a horizontal member 32 is attached to the tip end in the longitudinal direction. Two slits 32a are formed with a saw blade, and a part between the slits 32a is cut off with a groove cutter or the like to form a joint. Further, holes corresponding to the jaw portion 31a and the hole portion 31b formed on the side of the fitting 31 from the side near the joint are opened at three places with a hand drill or the like, and the bolts 33 are inserted into the two holes 32b and 32c. Then, when the horizontal member 32 is dropped from above so that the fitting 31 of the pillar member 30 and the joint of the horizontal member 32 are aligned with each other, the bolt 33 is caught on the jaw portion 31 a of the fitting 31. Then, the pin 34 is driven into the lowermost hole 32d,
The column member 30 and the horizontal member 32 are joined by penetrating the hole 31b of the metal fitting 31. In this series of operations, the positions of the holes 32b, 32c, 32d formed on the lateral side of the horizontal member 32 are determined to have predetermined dimensions from the end of the horizontal member 32, and the drilling position is the metal fitting to be used. It is standardized into 3 to 4 types according to

Conventionally, holes 32b, 32c, 32 are formed in wood 32.
In order to open d, measure the size of the drilling position with a scale, etc., against the vertices and top surface of the reference wood, and
There was a score line on the horizontal cross.

[0004]

In the conventional scoring method, it takes time to insert a scoring line, and the scoring is wrong due to misreading of the scale dimensions. If there is a hole at the hole position, there is a problem that the wood is wasted.

An object of the present invention is to solve the above-mentioned problems of the prior art and to enable accurate and easy scoring of hole positions in wood.

[0006]

[Means for Solving the Problems] The above object is to sandwich a right angle of a flat surface portion having a round or cross groove for scoring in a quadrangular scoring ruler in which a scoring line is formed in a hole position in wood. This is achieved by providing a wood mouth surface on two sides and an abutting surface that abuts the upper surface or the lower surface of the wood.

Further, two kinds of cross grooves corresponding to hole positions in the vicinity of the right end and the left end of the wood are formed on the flat surface portion,
One cross groove is chamfered from the front surface of the flat surface portion, and the other cross groove is chamfered from the back surface of the flat surface portion so that a scoring line is formed in a desired cross groove.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view of a scoring ruler, FIG. 2 is a plan view of FIG. 1, and FIGS. 3 and 4 are plan views showing examples of use of the scoring ruler.

Explaining one example of the hole positions in the wood,
A hole position 11 having a dimension a (69 mm) from the right tree mouth surface 10a of the wood 10 and a dimension d (50 mm) from the top surface 10b, the dimension b (104 mm) and the dimension e ( 120mm) hole position 12
Then, a hole is made at three places of hole position 13 of size a and size f (190 mm), and a total of three hole positions 14, 15 and 16 are made in the same manner as described above with the left mouth side and the upper surface of the wood 10 as reference positions. Drill holes in 6 places.

The scoring ruler 1 is made of a thin iron plate and is composed of a quadrangular plane portion 2. The top side portion 2a and the right side portion 2b, which are two sides that cross the right angle of the plane portion 2 as viewed from FIG. Is bent at a right angle to form abutting surfaces 3 and 4, and the lower side portion 2c and the left side portion 2d of the flat portion 2 are bent at a right angle to form abutting surfaces 5 and 6. The abutting surfaces 3 to 6 may be attached to the flat surface portion 2 at a right angle by welding or the like as a separate member other than bending the flat surface portion 2.

On the flat surface portion 2 is a right wood mouth surface 10a of the wood 10.
And cross grooves 7, 7 and 7 formed of vertical and horizontal grooves indicating the center points of the hole positions 11 to 13 on the basis of the upper surface 10b, and the wood 1 similarly.
Hole position 14 with reference to the left cutout surface 10c and the upper surface 10b of 0
Cross groove 8 consisting of vertical and horizontal grooves indicating the center point of
8 are provided. The groove widths of the cross grooves 7 and 8 are formed so that the tip (0.3 to 0.8 mm) of a writing instrument can be inserted therein. Instead of the cross grooves 7 and 8, round grooves 9 may be formed as shown in FIG.

When scoring corresponding to the hole positions 10 to 13 at the right end of the wood 10, as shown in FIG.
Of the ruler 1 on the wood 10 with the surface 2e of the
Then, the abutting surface 3 is abutted against the lower surface 10d of the wood 10 and the abutting surface 4 is abutted against the right wood mouth surface 10a of the wood 10. With this, the reference position of the scoring ruler 1 with respect to the wood 10 is set with the right wood mouth surface 10a and the upper surface 10b facing each other, and the scoring ruler 1 does not shift on the wood 10 during scoring. . In this state, the writing instrument 20 is inserted into the cross groove 7 and the scoring line 17 is inserted in the cross shape.

Next, when scoring corresponding to the hole positions 14 to 16 at the left end of the wood 10, the scoring ruler 1 is turned over so that the back surface 2f of the flat surface portion 2 faces up, and as shown in FIG. Abutting the upper surface 10b of the wood 10 and the abutting surface 6 against the left incision surface 10c of the wood 10 and making the left inward surface 10c and the upper surface 10b of the wood 10 abutting each other, the standard of the ruler 1 for the wood 10 Set the position. In this state, wood 1
0 The writing tool 20 is inserted into the cross groove 8 corresponding to the hole positions 14 to 16 at the right end, and the scoring line 18 is inserted in the cross. Although only the cross grooves 7 and 8 corresponding to one type of metal fitting are formed on the scoring ruler 1, the cross groove corresponding to the hole positions of a plurality of types of metal fittings may be formed on the flat surface portion 2. After the scoring work, an electric drill or the like is used to make a hole at the center point of the scoring lines 17 and 18.

Further, the hole positions 11 to 11 at the left and right ends of the wood 10
Since two kinds of cross grooves 7 and 8 are formed so as to correspond to 16, the scoring line 17 should be put in the cross groove 7 originally corresponding to the hole positions 11 to 13, but the erroneous hole positions 14 to 1 are mistaken.
There is a possibility that the cross groove 8 corresponding to 6 may be marked.
A configuration that solves this problem will be described with reference to FIGS. 5 is a plan view of a ruler for scoring showing a second embodiment, FIG. 6 is a sectional view taken along the line AA of FIG. 5, FIG. 7 is an enlarged view of a portion B of FIG.
FIG. 8 is an enlarged view of portion C of FIG. 6, and FIGS. 9 and 10 are explanatory views showing a state in which a writing instrument is inserted.

In FIG. 5, the cross groove 7 on the front surface 2e of the flat surface portion 2 is chamfered 7a, and the cross groove 8 on the back surface 2f is chamfered 8a. Thereby, for example, the surface 2 of the flat portion 2
When e is located on the upper surface, it can be visually observed that only the cross groove 7 is chamfered 7a. Therefore, if the scoring line 17 is to be placed in the cross groove 7 having the chamfer 7a, it is possible to check at a glance which cross groove the scoring line 17 should be placed in.

Further, as shown in FIG.
When the writing instrument 20 is inserted from the e into the cross groove 7 having the chamfer 7a, the tip 20a of the writing instrument 20 reaches the wood 10 and the scoring line 17 can be inserted. When the writing instrument 20 is inserted into the cross groove 7 from the back surface 2f, the writing instrument 2 is placed on the wood 10 as shown in FIG.
The point 20a of 0 does not reach.

Therefore, if the scoring line 17 is inserted in the cross groove 7 with the surface 2e of the flat surface portion 2 facing upward, even if the cross groove 8 (cross groove not chamfered) is accidentally scribed, The scoring line cannot be inserted, and the worker notices this scoring error. Therefore, it is possible to prevent double marking errors.

[0018]

As described above, according to the present invention, since the ruler for scoring is abutted on the two sides serving as the reference of the wood and the scoring line can be easily inserted along the cross groove with the pen for scoring, the scoring time can be reduced. It is fast and does not require a scale when marking lines, and can prevent mistakes due to incorrect reading of the scale.

Further, by chamfering one cross groove from the front surface of the flat surface and chamfering the other cross groove from the back surface of the flat surface, it is possible to confirm at a glance which cross groove should have the scoring line. In addition, even if an attempt is made to scribe a wrong cross groove, a scoring line cannot be inserted, so that a scoring error can be prevented twice.
