BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle measuring device for easily and continuously measuring any one of horizontal, vertical and inclination angles between arbitrary two points.

[0002]

2. Description of the Related Art For example, in the case of constructing a working hut, when a pillar is erected and viewed vertically, a method of measuring this is to hang a weight with a thread and adjust the consistency between the tip of the weight and the center line of the pillar. There is a way to see. In addition, when trying to make a wall by stacking blocks, a method is generally used in which water threads are stretched to match the length of the wall, and a leveler is applied to the top to check the levelness. In addition, when setting the inclination angle in the slope work of civil engineering work, first set the upper point and the lower point with optical instruments, then install the tensioning material according to the inclination angle between the upper point and the lower point. There is. In addition, as a case where no optical instrument is used, Japanese Patent Laid-Open No.
There was also a technology like that in No. 6-168111.

[0003]

[Problems to be Solved by the Invention] When viewing verticality, the weight sways, and it takes time and effort to stop the oscillation. In addition, if you move the center of the object to match the center line of the object such as a pillar to see the verticality with the tip of the weight, the weight will also sway, and it will take time for the sway to stop. was there. When looking at the levelness, I try to stretch the water thread and apply a leveler to the upper part, but the weight of the leveler causes the water thread to sink and the water thread itself loosens a little It has the drawback of being slightly damaged. In the slope work of civil engineering work, as shown in Fig. 6, the slope 20 is installed and then the slope is made, but the slope around the slope 20 is made according to the inclination angle. Although it is good to go, the inclination is difficult to understand at a place away from the tensioning 20, and as a countermeasure, the water thread 21 is fixed to the lower portions of the tensioning 20 with nails 22 and the tensioning is performed. The direction in which 20 is installed is that it is stretched in a direction at a right angle to see its levelness, but it takes time and hinders the work. The same thing can be said in JP-A-56-168111.

DETAILED DESCRIPTION OF THE INVENTION A description will be given below with reference to FIGS. Horizontal, vertical and tilt angles can be easily and accurately
And this device was invented for continuous measurement. The structure of the device shown in FIG. 1 has a supporting portion 15 including a finger hole 16 for the purpose of facilitating the handling of the device by inserting the fingers and holding the device with the palm. In order to make the main body 1 and this unit horizontal and vertical, they are mounted so that they are in a 90-degree relationship with each other.
And 1 as a set, and another set of leveling device C4 and leveling device D5 that are also attached to the main body 1 so that they are in a 90-degree relationship with each other. When you measure the angle with 4 attached levelers,
The protractor 6 for displaying an angle, a peripheral contact surface 13 which has the same center point as the angular center point of the protractor 6 and has the same radius, is formed on the side surface of the main body in contact with the protractor scale, and the protractor 6 A water thread 11 used to connect the device and an arbitrary measurement target point radially and linearly around the angle center point
Alternatively, the metal thread and the thread holder fixed hole 17 formed in the center of the protractor 6 as shown in FIG. 3 are used for fixing the water thread and threading the water thread, respectively, so that the projection light of the laser pointer 8 can be exchanged according to the use situation. The metal fitting 10 and the laser pointer holder 7 can be exchanged for use.

In the case of using a water thread, as shown in FIGS. 1, 2 and 3, the water thread 1 tied from this device to an arbitrary point to be measured.
1 passes through the water thread lead-out hole 14 of the metal thread fixing and water thread threading metal fitting 10 attached to the fitting hole 17 of the metal fitting and holder held at the center of the protractor 6 of the instrument, and then the water thread passage hole. 1
After passing through 2, and further wound by the water thread winding device 9, it is tightly tightened by being wound,
Water thread pull-out hole 1 of metal thread fixing and threading metal fitting 10
4, that is, the angle can be measured by moving continuously and radially around the angle center point of the protractor 6.

When the laser pointer is used, as shown in FIGS. 4 and 5, the laser pointer holder 7 is used to rotatably move the laser pointer 8 to the metal fitting and holder mounting hole 17 formed at the center of the protractor 6. Since it is mounted so that it can be moved, it can be moved radially around the angular center point of the protractor 6, and after the projection light of the laser pointer 8 is applied to any measurement point, the protractor attached to this unit The angle can be read by 6. In this case, the light emitting portion of the projected light at the tip of the laser pointer 8 is read by the protractor 6.

Next, the characteristics of the measuring instrument will be explained. The protractor 6 attached to this instrument has a scale of 0 ° to 90 ° and 90 ° to 0 °, which is obtained by dividing the full angle of the circle of 360 ° into four equal parts. It has a structure that combines four protractors. This makes 4
The indicator thread can be moved radially with reference to the 0 degree scale at each point. The peripheral contact surface 13 is formed on the side surface of the main body in contact with the protractor scale. Also, of the four levelers, level A2
And level device B3 as one set, and level device C4 and level device D5 as another set, so that the moving directions of the bubbles of the respective level devices of each set are perpendicular to each other in the horizontal direction. When the level gauge A2 and the level gauge B3 are level at the same time, or the level gauge C is attached.
4 and the level device D5 at the same time indicate that the level is horizontal, so that the level device can be kept horizontal when the specific level devices attached to the device are in synchronization with each other. . In addition, water thread 11 is used as an instruction thread for displaying the angle.
Alternatively, the projection light of the laser pointer 8 can be replaced and used as required.

As to how to use this device, as shown in FIGS. 1 to 3, first, a water thread 11 is attached from a water thread winding device 9 to a metal fitting and holder attachment hole 17 to fix and thread the water thread. Since it has been pulled out a little from the portion of the water thread pull-out hole 14 through the water thread passage hole 12 of 10, the water thread 11 is further pulled out and the tip of the water thread 11 is tied and fixed at an arbitrary measurement point. The water thread 11 continuously while moving the machine to the other measuring point, and at the time when the device has finished moving to the other measuring point, the water thread winding device 9
The water thread 11 is stretched by tightening and tightening the support portion 15 with a hand and pulling. And of the four levelers attached to this unit, leveler A2 and leveler B3
Basic use is horizontal use when and are located above, or vertical use when level devices C4 and D5 are located above.

On the other hand, since the circumferential contact surface 13 has the same center point as the protractor 6 and has the same radius, and is formed on the side surface of the main body in contact with the protractor scale, this peripheral contact surface 13 is formed. The water thread 11 which is brought into contact with the measurement surface and stretched between an arbitrary measurement target point and this device is used as the indicator thread of the angle scale.

Then, holding the supporting portion of this device, the water thread 11 is rotated on the angular scale of the protractor 6 as if the water thread 11 looks like a continuously moving wind. That is, since the circumferential contact surface 13 has the same center point and the same radius as the protractor 6, by continuously rotating the circumferential contact surface 13 while contacting it with the measurement surface, the water thread 11 Appears to move on its own on the angle scale of the protractor 6. Then, when the horizontal level A2 and the horizontal level B3 simultaneously indicate the horizontal level, or when the horizontal level C4 and the horizontal level D5 indicate the horizontal level, the angle scale indicated by the water thread 11 may be read.
On the contrary, with the level gauge A2 and the level gauge B3 of the instrument simultaneously indicating the level, or the level instrument C4 and the level instrument D5 indicating the level simultaneously, the water thread 11 is measured at an arbitrary object. It is also possible to move from the point and read an arbitrary angle on the angle scale of the protractor 6.

This device is provided with a finger hole 16 integrated with the support portion 15. It is possible to easily handle the instrument by inserting a finger into the finger-passing hole 16 and grasping the support portion 15 by hand, and by inserting the finger into the finger-passing hole 16 and pulling the water thread 11, It is also possible to have tension on 11.

This instrument measures the angle by emitting the projection light of the water thread 11 or the laser pointer 8 as an indicator thread from the center point of the protractor 6 and connecting it to an arbitrary measuring object point. Therefore, the exit of the projection light of the water thread 11 or the laser pointer 8 as the instruction thread is higher than the bottom portion of the instrument by the radius of the protractor 6. On slopes and general road surfaces,
When observing the tilt angle and horizontality of the measurement surface, the bottom surface of the instrument is placed in close contact with the measurement surface, and as shown in Figures 7-a and 7-c, the measurement target point on the other side is measured. X also needs to be raised by the radius of the protractor 6. The above is the case where only one unit is used.

When the water thread 11 is used, as shown in FIGS.
As shown in Fig. 8-c, using two units of this instrument, make the water thread 11 attract each other, and after adjusting the water thread 11 to 0 degree or 90 degree of the protractor scale of both instruments, set the horizontal direction of both instruments. When the level is adjusted with a container, the measuring point on this side and the measuring point on the other side are at the same height. In addition, even when the measurement is performed without the instrument being in close contact with the measurement surface, two instruments can be used to
0 degree or 9 on the protractor scale of both instruments
After aligning the water thread 11 at 0 degree, aligning the levels with the levelers of both instruments enables accurate and simple horizontal and vertical alignment between any two points. The above description is based on the assumption that the water thread 11 is used.

When the laser pointer 8 is used for the measurement, as shown in FIGS. 9-a, 9-b and 9-c, as in the case of using the water thread 11, the leveler A2 and the leveler B3 of this device are used. After the and indicate horizontal simultaneously, or in the state where the level C4 and level D5 simultaneously indicate horizontal, after freely moving the laser pointer 8 attached to the laser pointer holder 7, the angle is set. , Laser pointer 8
The small point Z on which the projection light hits is set as the set angle. Further, it is also possible to irradiate an arbitrary measurement target point Z with the projected light of the laser pointer 8 to set a small point Z on which the projected light hits and read the angle at that time on the angle scale of the protractor 6. At that time, the light emitting portion at the tip of the laser pointer 8 is read.

EFFECTS OF THE INVENTION A leveling device, a protractor, a circumferential contact surface having the same center point as the angle center point of the protractor and having the same radius and formed on the side surface of the main body in contact with the protractor scale, The present invention was invented in combination with water thread as a thread or projection light of a laser pointer. With this device, horizontal and vertical alignment between any two points and angle measurement can be performed easily and continuously in a short time, and the stitching work can be simplified.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle measuring device for easily and continuously measuring any one of horizontal, vertical and inclination angles between arbitrary two points.

[0002]

2. Description of the Related Art Usually, a so-called leveler is a rectangular parallelepiped body to which one or more bubble tubes, which are cylindrical glass tubes having bubbles inside, are attached. The purpose is to observe the position of bubbles when placed on the installation surface of the building and the top surface of the installed building, and to check the levelness.
When you want to use this leveler to determine the levelness between two distant points, you need to stretch the thread and look at the leveler. On the other hand, when obtaining the verticality from an arbitrary point, a work called a plumb bob is also performed in which a weight having a conical tip portion is attached to the tip of the thread and hung.

On the other hand, as a prior art in which the angle between two distant points can be measured or set, as a practical technique, Shokai 57-139.
In Japanese Patent No. 15 and Japanese Utility Model Laid-Open No. 58-130211, a protractor is used as a display unit, and the protractor or index is moved by a water thread to measure or set. In Japanese Utility Model Laid-Open No. 4-69702, a method using a tape measure is used, and in Japanese Utility Model Laid-Open No. 9-10795, the light emitted from a laser pointer is used. In Japanese Utility Model Laid-Open No. Sho 19-19109, a leveler is integrated with the thread itself. When setting the inclination angle in the slope construction, first set the upper point and the lower point by the optical instrument, and then install the stakes according to the inclination angle between the upper point and the lower point. The one disclosed in Japanese Utility Model Application Laid-Open No. 56-16811 is a technique using a tensioning material.

[0004]

Although it is possible to check the levelness using a leveler, it is not possible to obtain an arbitrary angle. In addition, when you look at the horizon with a water level on it, the weight of the horizon may cause the water thread to sink, or the water thread itself may become loose while being stretched for a long time. On the other hand, even in plumbing work, it takes time before the weight stops, and there is the influence of wind. In addition, it is difficult to understand the tilt angle in a place away from the surrounding area of the tensioning during slope work.
As shown in FIG. 6, the parallel tensions 30 are attached to each other by the water thread 3
1 is fixed with nails 32 and the direction in which the tensioner 30 is installed is to extend in a direction at a right angle to see its levelness, but it takes time and hinders the work.

On the other hand, the one disclosed in Japanese Utility Model Laid-Open No. 57-13915, which is given as an example of the prior art, seems to have a small range of measurable angles. In addition, in Japanese Utility Model Laid-Open No. 58-130211, it is doubtful how to check the level without a leveler. In Japanese Utility Model Laid-Open No. 4-69702, a tape measure and a goniometer are combined, but the tape measure is affected by the condition of the road surface (measurement surface). In Japanese Utility Model Laid-Open No. 9-10795, the light emitted from the laser pointer is used, but the light of the laser pointer is very difficult to see under bright light in the daytime. In all of the above five types of measuring instruments, it is necessary to bring the main body into contact with the surface to be measured. In Japanese Utility Model Laid-Open No. Sho 64-19109, the measurer cannot see the leveler. The one disclosed in Japanese Utility Model Laid-Open No. 56-16811 requires time and labor for installation.

From the above, considering an ideal instrument for angle measurement, the operator himself can easily handle it, and it does not take time and time for installation, and a wide range of angles can be measured. There is a demand for a device that is not easily affected by the condition of the measurement surface and has a long measurable distance.

[0007]

In order to achieve the above object, an angle measuring device according to claim 1 of the present application is attached to a main body, a water thread provided in the main body, and the angle center point. It is composed of a protractor that operates a water thread as a base point and a bubble level that is mounted on a surface substantially perpendicular to the surface on which the protractor is mounted.

[0008] With this, a water thread is stretched between the main body and an arbitrary measuring point, the position of the air bubble of the bubble type spirit level attached to the main body is adjusted, and the horizontality of the main body is determined. Read the angle indicated by the water thread on the angle scale of the attached protractor.

The protractor 6 of the angle measuring device of claim 2 is used as an angle display portion. The feature is that the angle scale has a structure that combines four 90-degree protractors, which are composite scales of 0 degrees to 90 degrees and 90 degrees to 0 degrees in different directions, and the angle center of the protractor 6. The water thread 11 is pulled out from the point and used. Then, the four 0-degree scales are used as the angle reference line, and the water thread 11 is instructed the angle with the angle center point, which is one end of the angle reference line, as the base point. The water thread 11 is pulled out from a water thread drawing hole 14 which is an angular center point of the protractor 6. Further, since the circumferential contact surface 13 is formed along the scale of the protractor, the circular shape of the protractor can also be used for measurement.

The bubble tube level of the angle measuring device according to claim 3 may have a shape in which a substantially circular object is attached to the upper surface portion and the right side surface portion, but in the present application, movement of bubbles to each other on the upper surface portion. Two bubble tube level A (2) so that the direction of movement is vertical
And B (3) as one set, and another set C (4)
And D (5) were similarly attached to the right side surface. By installing two sets, it is possible to set the angle in the horizontal direction with the protractor of this device flat. Further, by attaching another set to the lower surface, the usability is further improved. In this case, a substantially circular object may be attached.

In the angle measuring device of the fourth aspect, the grasping portion 15 puts a finger into the finger passage hole 16 and grasps firmly with the palm,
The first purpose is to provide tension to the water thread 11 by holding it loosely, and the second purpose is to improve operability.

Explaining the first object, the present device puts out the water thread 11 from the angular center point of the protractor 6 and stretches it between an arbitrary measuring point, and the angular center point on the angular scale of the protractor 6 serves as a base point. However, at this time, the water thread 11 as the instruction thread is required to have no slack, so holding the grip portion 15 of the device slightly (or the measurement point of the other side). It is possible to give proper tension to the water thread 11 (by pulling it from one side). Therefore, the first purpose of the grip portion of the device is to give tension to the water thread 11.

The second purpose is to improve operability. By firmly grasping the grip, the instrument can be operated freely with one hand up / down / left / right. At the time of measurement, while adjusting the bubble position of the bubble level with the water thread 11 having an appropriate tension and making it horizontal, the protractor scale indicated by the water thread 11 is read, but these series of operations can be performed smoothly. The reason is that it has a gripping part.

The peripheral contact surface and the ground contact surface of the angle measuring device according to claim 5 are formed and set as a measurement reference surface on a surface substantially perpendicular to the surface to which the protractor 6 attached to this device is attached. It was done. The circumferential contact surface 13 is a variable reference surface formed along the protractor scale, and is capable of continuously moving a contact point which is a reference surface with respect to the measured surface. On the other hand, the ground contact surface is a fixed reference surface, and the upper surface is used as the upper ground contact surface 18, the right side surface is used as the side ground contact surface 19, and the lower surface is used as the lower ground contact surface 20. The four 0-degree graduations of the protractor 6 are in parallel or perpendicular relation to each ground plane. When the bubble tube levelers A (2) and B (3) attached to the upper surface of the instrument are horizontal, the upper ground plane 18 and the lower ground plane 20 are in a horizontal state and The ground 19 is vertical. And when the bubble level C (4) and D (5) are horizontal,
The side ground plane 19 is in a horizontal state, and the upper ground plane 18 and the lower ground plane 20 are in a vertical state.

As a result of the above, the circumferential contact surface 13 is used as a variable reference surface for measuring slopes such as slopes and road surfaces. On the other hand, the lower ground contact surface 20 is used when setting a slope such as a slope or a road surface,
It is used for horizontal and vertical alignment when the surface to be measured is flat. Also, if the plumb bob is used in combination with this device, the inclination of the ceiling surface can be measured on any of the upper ground surface 18, the side ground surface 19, and the lower ground surface 20. And if you use a small object with a plumb bob, it is possible to measure slopes such as slopes and roads. This is possible because the four 0 degree graduations of the protractor 6 are in parallel or perpendicular relation to the respective ground planes.

The laser pointer of the angle measuring device according to claim 6 has the drawback that the projected light of the laser pointer is very difficult to see under bright light in the daytime, but if the outdoors is twilight, it is in the daytime. Even if it is used, and that it is more likely to be used indoors, paying attention to the fact that the projected light of the laser pointer can instantly indicate a far point and that it is easy to handle. It is an object to be used as an indicator thread instead of the water thread of claim 1.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing an angle measuring device according to an embodiment having claims 1 to 5 of the present application. The appearance of this device is composed of a circle, two parallel lines that are tangents to the circle, and one perpendicular line to the parallel line. From a different point of view, this is a shape that combines a circle and a quadrangle with the diameter of the circle as one side. The protractor 6 is attached to the circle portion, and the water thread 11 is pulled out from the angular center point of the protractor 6. A finger-passing hole 16 was drilled in the rectangular portion and a grip portion 15 was provided. Then, a set of two levelers is provided on the upper surface with leveler A (2) and leveler B (3), and on the right side with leveler C.
(4) and leveler D (5) were attached.

On the other hand, the surface substantially perpendicular to the surface to which the protractor 6 is attached is a peripheral contact surface formed in contact with the protractor scale, and the three surfaces of the quadrangular portion are respectively the upper ground surface 18 and the side contact surface. It was used as the ground 19 and the lower ground contact surface 20.

FIG. 2 is a top view of the angle measuring device of FIG. 1, and FIG.
FIG. 3 is a partial structural view of FIG. 2. As shown in FIG. 3, a water thread 11 connected from an arbitrary measuring point to this unit is attached to a metal fitting and a holder mounting hole 17 formed in the center of the protractor 6 for fixing and threading the water thread. After passing through the water thread drawing hole 14 of the metal fitting 10, the water thread passing hole 12 is further wound up by the water thread winding device 9 as shown in FIG. With a slight grip, it has sufficient tension, and can be moved radially and continuously around the water thread pull-out hole 14 of the metal thread fixing and water threading metal fitting 10, that is, the angle center point of the protractor 6. The angle scale on the protractor 6 can be designated. At this time, the level is determined by either set of the bubble type spirit level attached as a set of two on the upper surface part and the right side surface part of the instrument, and then the water thread 1
The angle can be measured by reading the angle scale on the protractor 6 indicated by 1.

The characteristics of the measuring device will be described below. This device is premised on that most of the conventional devices for measuring angles are used with the body itself in contact with the surface to be measured. Unlike the above, it is not necessary to make contact with the surface to be measured, and the angle can be measured even if the measurement point on the other side is simply in the air or the device itself is placed in the air.

This is made possible by the fact that this device uses the water thread 11 as the indicator thread, and that the grip portion 15 including the finger hole 16 is provided so that it can be securely gripped with five fingers and the palm. This means that the operator can operate it freely with one hand, and the measurer can move the bubble of the level and the movement of the water thread 11 on the scale of the protractor.
You can measure the angle by adjusting the points.

Further, the present apparatus is provided with a peripheral contact surface 13 and three grounding surfaces, namely, an upper grounding surface 18, a side grounding surface 19 and a lower grounding surface 20, which are supposed to be used in contact with the surface to be measured. Since it has a road surface, a slope, a ceiling surface, etc.

As an example of how to use this device without contacting the measuring surface as a way of using this device, as shown in FIG. 2, the water thread 11 is first fed from the water thread winding device 9 to the metal fitting and holder mounting holes. As shown in FIG. 7, the water thread 11 is further pulled out because it has passed through the water thread passage hole 12 of the metal thread fixing and water threading metal fitting 10 attached to 17 and has been slightly pulled out from the water thread drawing hole 14. Similarly, the tip of the water thread 11 is tied and fixed to an arbitrary measurement point, and the water thread 11 is continuously ejected while moving the device to the other measurement point.

Then, when the device is moved to the other measurement point, the water thread winding device 9 is wound up and
The water thread 11 is tensioned by firmly grasping and pulling the grip portion 15. And, among the four bubble tube type spirit levels attached to this unit, the level level installed on the upper surface using the set of the spirit level A (2) and the spirit level B (3) or on the side surface. While using the set of C (4) and level D (5) to determine the horizontality of the device, the water thread 11 is adjusted on the angular scale of the protractor 6 so as to show the 0 ° scale.

The level of the level A (2) and the level B (3) or the level of the level C (4) and the level D (5) simultaneously shows the horizontal level, and the water thread 11 is the protractor. When showing the 0 degree scale on the angle scale of 6, the water thread 11 stretched between any measuring point and this device is in the horizontal state, and the leveling is completed. Further, vertical alignment can be performed as shown in FIG. In addition, when setting or measuring an arbitrary angle, it is shown in Fig. 9 that the device is moved up or down and the operation according to the leveling is performed.

When they are used in contact with each other, any one of the circumferential contact surface 13, the upper ground surface 18, the side ground surface 19 and the lower ground surface 20 is used. As shown in FIG. 1, since the pull-out hole of the water thread 11 has a height corresponding to the radius of the protractor 6, even if the condition of the road surface is uneven, it is less affected, but on the other side of this device. Even at the measurement point, it is necessary to give the water thread 11 a height corresponding to the radius of the protractor.

First, the case where the circumferential contact surface 13 is brought into contact with each other for use will be described. In the inclined surface as shown in FIG. 10, the circumferential contact surface 1
3 is brought into contact with the surface to be measured, and the water thread 11 stretched between any point to be measured and the instrument is used as an indicator thread of the angle scale, and the grip of the instrument is held and the angle scale of the protractor 6 is adjusted. Rotate the water thread 11 so that it moves continuously.

The water level 11 indicates when the level C (4) and the level D (5) or the level A (2) and the level B (3) are simultaneously horizontal. The measurement is completed by reading the angle scale on the protractor 6.

An example in which the lower ground plane 20 is used is shown in FIG. 11 as a ground plane usage example. In addition, if the plumb bob y is used in combination with this instrument, the inclination of the ceiling surface can be measured as shown in FIG. 12, and if it is a small plumb bob that fits within the radius of the protractor 6, the road surface, slope, etc. The slope of can also be measured.

If two of these instruments are used to draw each other, more accurate measurement is possible, and various utilization methods are possible. An example is shown in FIG.

When the laser pointer is used instead of the water thread as the indicator thread, the laser pointer 8 is diverted by the laser pointer holder 7 as shown in FIGS. Mount it so that it can be rotated around the angle center point of 6. And one set of bubble level A (2) and B (3) or C (4) and D attached to the main body
After confirming the horizontality by a set of (5), the projection light of the laser pointer 8 is applied to an arbitrary measurement point, and the light emitting portion of the tip of the laser pointer 8 is arbitrarily set on the angle graduation on the protractor 6. To the angle of. For example, if leveling is performed, the angle scale of 0 degrees may be set in the horizontal direction.

In this device, the protractor scale of the protractor 6 is made flat, and the levelness is determined by the level device B (3) and the level device D (5), and the water thread 11 or the laser pointer 8 is set. You can also use to set the angle in the horizontal direction.
