  However, the conventional portable verticality measuring instrument has the following problems to be solved. In the measuring instruments disclosed in Patent Documents 1 to 3, the display surface cannot be easily confirmed from the position where the worker is away. In Patent Document 1, the display surface is facing upward, and an operator needs to stand beside the installed pole and look into the display surface from above. In the measuring instrument disclosed in Patent Document 2, two display surfaces face sideways, but face different directions. Therefore, the worker cannot confirm both display surfaces simultaneously from a remote position.

  In the measuring instrument disclosed in Patent Document 3, an operator can check the display surface from the same side. However, the display surface that displays the tilt in the left-right direction is a plane that faces sideways, but the display surface that displays the tilt in the front-rear direction is an arc surface. When the arc surface is viewed from the front, the position of the pointer moving up and down along the arc surface may not be easily confirmed. In addition, the tilt in the left-right direction is displayed by a pointer that moves left and right, while the tilt in the front-rear direction is displayed by a pointer that moves up and down along the arc surface. For this reason, it may be difficult to understand the state in which the degree of verticality in the front-rear direction is obtained by simply looking at the display surface.

  In view of these points, the problem of the present invention is that the front, rear, left and right tilt states can be displayed on the same plane, and it can be immediately understood that the vertical degree is obtained in the front, rear, left and right with a glance at the display surface. The purpose of this is to propose a perpendicularity measuring device.

In order to solve the above problems, the verticality measuring instrument of the present invention is
Case and
A display board attached to the case;
A vertical scale line formed on the display surface of the display board and extending in the vertical direction of the display board; and a horizontal scale line extending in the horizontal direction of the display board perpendicular to the vertical scale line;
A first pointer suspended from the first support shaft in a swingable manner in the left-right direction about the first support shaft perpendicular to the display surface on the display surface;
A second pointer suspended from the second support shaft in a swingable manner in the left-right direction about the second support shaft perpendicular to the display surface on the display surface;
A pendulum suspended from the third support shaft in a swingable manner in the front-rear direction of the display surface around a third support shaft parallel to the horizontal scale line inside the case;
A swing arm extending in a direction from the swing center of the pendulum toward the display plate and swinging in the vertical direction of the display plate when the pendulum swings in the front-rear direction;
Have
The tip of the swing arm protrudes forward of the display surface from a through hole formed in the display plate, and engages with a portion of the second pointer that is disengaged in the left-right direction from the second support shaft. It is characterized by being.

  The perpendicularity measuring instrument of the present invention is used by being attached to a member to be measured, for example, a side surface of a pile. Attach the verticality measuring instrument to the side of the pile so that the vertical scale line coincides with the center axis of the pile. The state in which the first pointer coincides with the vertical graduation line is a state in which the verticality in the left-right direction of the pile is obtained. Moreover, the state in which the second pointer coincides with the horizontal graduation line is a state in which the verticality in the front-rear direction of the pile is obtained. The piles can be driven vertically by correcting the posture of the piles so that both pointers coincide with both index lines.

  The inclination of the pile in the left-right direction and the inclination in the front-rear direction can be confirmed by viewing the first and second pointers arranged on the same display surface from the same direction. Therefore, it is possible to easily know the verticality of the front, rear, left and right of a pile or the like.

  Here, in order to enable the verticality measuring device to be easily attached to the side of the pile or column to be measured, the case is attached to the case of the verticality measuring device of the present invention. It is desirable to have a magnet attached.

In the perpendicularity measuring instrument of the present invention,
The second spindle is located at the intersection of the vertical scale line and the horizontal scale line;
The first support shaft is located on the vertical scale line below the intersection;
A first vertical indicator line extending from the center of the first support shaft is formed on the surface of the first pointer,
A second vertical index line and a horizontal index line extending in a direction orthogonal to each other from the center of the second support shaft are formed on the surface of the second pointer.
When the display surface faces the direction of gravity without tilting in the left-right direction, the first vertical index line coincides with the vertical scale line;
It is desirable that the second vertical index line coincides with the vertical scale line and the horizontal index line coincides with the horizontal scale line when the display surface is directed in the direction of gravity without tilting in the front-rear direction.

  If comprised in this way, when the perpendicularity of the front and rear, right and left of a pile and a column to be measured is obtained, the first vertical index line of the first pointer and the vertical index line of the second pointer are aligned on a straight line. Therefore, it is possible to know whether or not the vertical degree of the front, rear, left and right is obtained only by glance at the display surface.

  In this case, in order to improve the visibility from a distant position, the display surface is color-coded with the vertical scale line and the horizontal scale line as a boundary, and the surface of the first pointer is the first vertical index. It is preferable that the lines are color-coded on the boundary, and the surface of the second pointer is color-coded on the boundary of the second vertical index line and the horizontal index line.

  Embodiments of a perpendicularity measuring device to which the present invention is applied will be described below with reference to the drawings. FIG. 1 is a front view of a verticality measuring instrument according to this embodiment, and FIGS. 2 and 3 are a front perspective view and a rear perspective view thereof. 6-8 is a figure which shows 6 surfaces of a perpendicularity measuring device. Referring to these drawings, the verticality measuring instrument 1 includes a case 2, a display board 3 attached to the front surface of the case 2, and two magnets 4 a and 4 b attached to the rear surface of the case 2. ing.

  The case 2 has a predetermined height that is bent so as to have a substantially square groove-shaped cross section. The display board 3 is fixed to the case 2 so as to seal the opening in front of the case 2. The display board 3 has the same height as the case 2, but is wider than the case 2. The magnets 4a and 4b have a disk shape, and are fixed to the back plate 2a of the case 2 by fixing screws 5a and 5b attached so as to penetrate through the central portions thereof. By the magnets 4a and 4b, the verticality measuring instrument 1 is attached to the side surfaces of the piles, columns, etc. to be measured. In addition, rectangular through holes 3 a to 3 d are formed at four corners of the display panel 3. When the measurement target pile or pillar is made of a material such as wood, the perpendicularity measuring device 1 can be attached to the measurement target pile, pillar, or the like through a fastener such as a fastening band through the through holes 3a to 3d.

  The display board 3 has a flat display surface 6. A vertical scale line 7 and a horizontal scale line 8 are drawn on the display surface 6. The vertical scale line 7 extends from the middle position in the vertical direction to the lower edge 6 a of the display surface 6 at the center in the left-right direction of the display surface 6. The horizontal scale line 8 extends from the upper end of the vertical scale line 7 to one side edge 6 b in the left-right direction of the display panel 3. The surface color of the display surface 6 is a first color such as black. In this example, the rectangular area surrounded by the vertical graduation line 7, the horizontal graduation line 8, the lower edge 6a and the side edge 6b is filled with a second color that is easily visible, such as yellow, which is different from the first color. This is a colored area 9. In the figure, the portion displayed in gray is a colored region 9.

  A first pointer 11 and a second pointer 12 made of a plate material are arranged on the display surface 6. The first pointer 11 has a rectangular outline that is long in the vertical direction, and its lower end is pointed in a mountain shape downward. The upper end portion of the first pointer 11 is suspended from the first support shaft 13 while being swingable in the left-right direction of the display surface 6 about the first support shaft 13 fixed perpendicularly to the display surface 6. It has been. The first support shaft 13 is located on the vertical scale line 7 below the intersection of the vertical scale line 7 and the horizontal scale line 8 on the display surface 6.

  The second pointer 12 has a flat T shape including an elongated rectangular arm portion 12a extending in the left-right direction and a leg portion 12b projecting downward from the center in the left-right direction of the arm portion. An end of the arm portion 12a on the side edge 6b side of the display surface 6 is a tip end pointed in a mountain shape. The second pointer 12 has the center portion of the arm portion 12a swingable in the left-right direction of the display surface 6 about the second support shaft 14 fixed perpendicularly to the display surface 6. It is suspended from the support shaft 14. The second spindle 14 is located at the intersection of the vertical scale line 7 and the horizontal scale line 8.

  Here, on the surface of the first pointer 11, a first vertical index line 15 extending linearly in the length direction of the first pointer 11 from the center of the first support shaft 13 is drawn. In this example, with the first vertical index line 15 as a boundary, the colored region 9 side of the display surface 6 is filled with the same second color as the colored region 9, and the other is the first of the display surface 6. It is the same color as

  On the surface of the second pointer 12, a straight horizontal index line 16 extending from the center of the second support shaft 14 to the tip side is drawn on the arm portion 12a. A straight second vertical index line 17 extending downward from the support shaft of the second support shaft 14 is drawn on the leg portion 12b. Also on the surface of the second pointer 12, the colored region 9 side of the display surface 6 is filled with the same second color with the horizontal index line 16 and the second vertical index line 17 as a boundary, and the other region Is the same color as the first color of the display surface 6.

  Next, FIG. 4 is a longitudinal sectional view of the verticality measuring instrument 1. As can be seen from this figure, in the case 2, the third support shaft 21 is bridged between the case side plates 2 b and 2 c on both sides thereof. The third spindle 21 extends in parallel with the horizontal scale line 8 at the same height as the horizontal scale line 8 drawn on the display surface 6. An upper end portion of a plate-like pendulum 22 is suspended from the third support shaft 21 so as to be swingable in the front-rear direction of the display plate 3. A weight 23 is attached to the lower end portion of the pendulum 22.

  A swing arm 24 is integrally formed at the upper end of the pendulum 22 so as to bend and extend at a right angle from the center of the third support shaft 21 toward the front toward the display panel 3. When the pendulum 22 swings in the front-rear direction about the third support shaft 21, the swing arm 24 swings up and down about the third support shaft 21.

  A tip end 24 a of the swing arm 24 protrudes forward from a through hole 3 e formed in the display panel 3. As shown in FIG. 1, the through hole 3 e is a long hole that is long in the vertical direction so as not to interfere with the distal end portion 24 a of the swing arm 24 that swings in the vertical direction. The front end portion 24 a protruding forward is engaged with a through hole 12 c formed in the arm portion 12 a of the second pointer 12. As shown in FIG. 1, the through-hole 12 c is formed in a portion of the arm portion 12 a that is off the rear end side from the center of the second support shaft 14. The tip portion 24a is engaged with the through hole 12c in a slidable state in the left-right direction. When the tip 24a of the swing arm 24 swings in the vertical direction, the second pointer 12 engaged therewith swings in the vertical direction around the third support shaft 21.

  FIGS. 5A and 5B are explanatory diagrams showing the usage state of the verticality measuring instrument 1. For example, when driving a pile vertically into the ground, the verticality measuring instrument 1 is attached to the side surface of the pile 30. The verticality measuring instrument 1 is attached so that the vertical scale line 7 of the display surface 6 of the verticality measuring instrument 1 coincides with the central axis of the pile 30. The display surface 6 of the verticality measuring instrument 1 is visually observed, and the presence or absence of the inclination of the pile 30 in the left-right direction and the front-rear direction can be confirmed by the first pointer 11 and the second pointer 12.

  If the first pointer 11 coincides with the vertical scale line 7 of the display surface 6, the pile 30 is vertical in the left-right direction of the display surface 6. FIG. 5A shows this state. When the first vertical index line 15 of the first pointer 11 matches the vertical scale line 7 of the display surface 6, it can be confirmed that there is no inclination of the pile 30 in the left-right direction.

  When the pile 30 is inclined in the front-rear direction of the display surface 6, the display surface 6 is inclined in the front-rear direction with respect to the hanging direction of the pendulum 22. Accordingly, the swing arm 24 of the pendulum 22 faces in a direction inclined upward and downward with respect to the display surface 6. For this reason, the second pointer 12 engaged with the distal end portion 24 a of the swing arm 24 is tilted about the second support shaft 14 and tilted with respect to the horizontal scale line 8 of the display surface 6. That is, the horizontal indicator line 16 of the second pointer 12 is inclined with respect to the horizontal scale line 8 of the display surface 6. Further, the second vertical index line 17 of the second pointer 12 is inclined with respect to the vertical scale line 7 of the display surface 6. FIG. 5A shows this state. By adjusting the direction of the pile 30 in the front-rear direction so that they match, the inclination of the pile 30 in the front-rear direction can be eliminated.

  As shown in FIG. 5B, the first pointer 11 and the second pointer 12 intersect at a right angle on the display surface 6 in a state where the verticality in the front-rear and left-right directions is obtained. Therefore, it is possible to know whether or not the verticality of the pile or the like has been obtained only by glance at the display surface 6.
