[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a positioning tool for an electronic measure suitable for measuring the width and length of a site when building a house or the like.

[0002]

[Prior Art]

 Generally, when building a house, the width and length of the site and the position where the foundation should be installed were measured using a tape measure. However, in recent years, instead of a tape measure, by transmitting ultrasonic waves (or infrared rays) to a reflector such as a wall and receiving the ultrasonic waves reflected from the reflector, the distance from the time from transmission to reception can be reduced. Measuring electronics measures have come into use.

This electronics measure is a box having a size equivalent to that of a new edition, and has an ultrasonic wave emitting section for transmitting and receiving ultrasonic waves on its front end face. An ultrasonic wave transmitting device and a microcomputer are built in the electronics measure, and the distance from the time difference to the reflector can be instantly measured within an error range of 1% or less. In addition, the electronics measure has a simple calculation function. For example, the area of a room can be calculated by measuring the length and width of the room.

Conventionally, when measuring the distance from the wall to the wall of a room by using such an electronic measure, for example, a measurer should contact the rear end surface of the electronic measure with the side surface of one wall. Supports the electronics measure by hand and radiates ultrasonic waves to the other wall. At this time, the electronics measure displays the distance from the rear end of itself to the reflector by adding the distance from the front end to the rear end of itself to the distance obtained from the time difference from the transmission of ultrasonic waves to the reception of ultrasonic waves. It is like this.

As described above, the electronic measure is in a state where it is easily supported by the measurer by hand without the trouble of extending the other end while keeping one end at the measurement position like a tape measure. Therefore, the distance from the electronics measure to the reflector can be accurately measured.

[0006]

[Problems to be solved by the device]

 By the way, as described above, the electronic measure is extremely small and lightweight, easy to handle, and extremely convenient when measuring the distance from wall to wall in a divided space such as a room. However, it was difficult for the electronics majors to measure the distance by using the markings provided on the ground such as boundary markings and piles as a standard on the land that is not divided. This is because the distance can be easily measured only by supporting it by the operator. In other words, the electronic measure has a structure in which the distance is measured with its rear end face abutting against a wall, so that the measurer can only support it by hand in a place without a break. It was difficult to measure the distance accurately.

In addition, when there is a sloped part on the site, it is possible to measure the distance along the slope, but in order to measure the horizontal distance and the height of the sloped part, The law had to be used, and a person with specialized knowledge such as a surveying engineer was required.

The present invention has been proposed in view of the above circumstances, and an object of the present invention is to set the distance between two points as a standard based on the marking provided on the ground such as a boundary mark or a pile. An object of the present invention is to provide a positioning tool for an electronic measure that can easily position the electronic measure when measuring with a measure.

[0009]

[Means for Solving the Problems]

 The electronic measure positioning device of the present invention is an electronic measure positioning device for positioning an electronic measure for measuring distance by reflection of ultrasonic waves on a marking on the ground such as a boundary mark. A tripod supporting the measure, a cylindrical rotary shaft that vertically penetrates the center of the base of the tripod, and is rotatably supported by the base, and an upper part of the rotary shaft integrally with the rotary shaft. , A support plate which is rotatably supported to the left and right and horizontally supports the electronic measure, and the rotation shaft has an upper end serving as an eyepiece so that it can be seen directly below the tripod. The fact that the above has become is the solution to the above-mentioned problems.

In the present invention, the support plate is rotatably supported in the vertical direction by the rotation shaft so that the direction of the ultrasonic wave emitted by the electronic measure can be changed up and down. Further, an electronic goniometer that rotates integrally with the support plate is attached so as to measure the angle of the radiation direction of the ultrasonic wave with respect to the horizontal line.

[0011]

[Action]

 According to the above configuration, in the positioning device of the present invention, the rotary shaft attached so as to penetrate the pedestal has a cylindrical shape, and it is possible to look down from the upper end thereof. After standing the tripod, looking down from the hole of the rotation axis, align the center of the hole of the rotation axis with the center of the boundary mark, and shift the position of the tripod to accurately position the electronics measure. Can be aligned with the boundary mark. Then, when measuring the distance, a reflecting plate for reflecting ultrasonic waves is installed at a point where the distance from the boundary mark is measured, and the electronic measure is measured in the direction of the reflecting plate.

When there are a plurality of points where the distance from the boundary mark is measured, the electronics measure is rotated about the rotation axis, so that the position of the electronics measure is not displaced from the boundary mark and the ultrasonic wave is transmitted. Since the radiation direction can be changed, measurement can be performed without re-aligning the electronics measure.

Further, by mounting the support plate on the rotary shaft so as to be vertically rotatable, the distance between two points along the slope of the slope can be easily measured. At this time, the angle of the electronics measure is obtained together with the distance between the two points on the sloping land by the electronics goniometer, and the horizontal distance and the height difference between the two points can be easily obtained from the distance and the inclination angle. ..

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 are drawings showing a positioning tool A of an electronic measure according to the present embodiment. The positioning tool A is used when the electronic measure 1 is used to measure a distance between two points. The position of is accurately aligned with the markings such as boundary marks and piles on the ground.

As shown in FIG. 3 and the like, the positioning tool A vertically penetrates a tripod 2 supporting an electronic measure 1 and a pedestal 3 of the tripod 2 and is rotatably supported by the pedestal 3. A cylindrical rotary shaft 4, an angle-shaped support plate 5 rotatably attached to the upper part of the rotary shaft 4 up and down, and an electronic goniometer 6 attached to the side surface of the support plate 5. And a reflection plate 7 attached to the upper surface of the support 5 plate.

The tripod 2 is a known tripod as shown in FIGS. 1 and 3, and the three legs 2a ... Are rotated on the lower surface of the plate-like base 3 so as to open in three directions at a predetermined angle. It is attached so that it can move freely. Each of the three legs 2a is formed by inserting thin cylinders having different diameters into the through holes of the thick cylinders in order of diameter. Then, the length of the leg 2a can be adjusted so that the pedestal becomes horizontal.

The rotating shaft 4 is a pipe formed in a tubular shape with a through hole 4a formed along the center line thereof. The upper part of the rotary shaft 4 is tapered so that its diameter becomes wider toward the upper end to form an eyepiece part 4b. Further, columnar shafts 4c and 4c extend rightward and leftward at right angles to the length direction of the rotating shaft 4 below the eyepiece 4b of the rotating shaft 4.

The rotary shaft 4 is arranged at the center of the base 3 of the tripod 2 so as to penetrate the base 3 at a right angle. The portion of the pedestal 3 through which the rotary shaft 4 penetrates serves as a well-known bearing that rotatably supports the rotary shaft 4. The support plate 5 is formed in an angle shape from a rectangular plate-shaped upper plate 5a and a side plate 5b extending downward from one side edge of the plate 5a.

The upper plate 5a is formed with a long hole 5c extending from the center of the upper plate 5a to the rear side along the length direction of the upper plate 5a. The rotary shaft 5 is inserted into the elongated hole 5c. Then, on the upper surface of the upper plate 5a, projecting portions 5d and 5d, which serve as bearings for the shaft 4c of the rotary shaft 4, are provided at positions on the left and right sides of the elongated hole 5c. A fitting hole 5e into which the shaft 4c of the rotary shaft 4 is rotatably fitted is formed in the protrusions 5d and 5d.

Based on such a configuration, the support plate 5 is rotatable left and right integrally with the rotation shaft 4 that is rotatable with respect to the pedestal 3 of the tripod 2, and the support plate 5 is also rotatable. The protrusions 5d and 5d are supported by the shaft 4c of the rotary shaft 4 so that the front part of the support plate 5 can rotate up and down.

Further, the shaft 4c of the rotary shaft 4 is tightly fitted in the fitting hole 5e of the protrusion 5d, and the operator can manually rotate the support plate 5 up and down. However, the support plate 5 does not rotate under its own weight including the electronics measure 1 and the like, so that it does not move from an angle determined by the operator.

The shaft 4c of the rotary shaft 4 is provided with a recess (not shown), and the fitting hole 5e of the protrusion 5d is urged by a spring (not shown). A substantially conical locking part (not shown) that can be retracted and retracted is provided, and when the support plate is at a right angle to the rotation axis, the locking part fits into the recess, thereby supporting the support plate 5 It can be fixed. It should be noted that this fixing can be easily released by moving the support plate 5 by hand.

As described in the conventional example, the electronics measure 1 emits ultrasonic waves from its front end, measures the time until the ultrasonic waves bounce off a reflector such as a wall and return. To measure the distance. The electronics measure 1 is formed in a rectangular box shape, and an ultrasonic wave radiating section 1a for transmitting and receiving ultrasonic waves is provided on the front end surface thereof. In addition, on the upper surface of the electronics measure 1, a digital display unit 1b for displaying a measurement value is provided, and an operation switch (not shown) and the like are provided.

The lower surface of the electronic measure 1 is attached to the upper plate 5 a of the support plate 5. Then, the center line along the length direction of the upper plate 5a and the radiation direction of the ultrasonic waves of the electronics measure 1 are parallel to each other. Further, a pyramidal protrusion 1c is attached to the center of the width of the upper surface of the electronics measure 1.

The electronics goniometer 6 has a tilt box sensor (not shown) built in a box 6a in the shape of a rectangular box, and when the box 6a is tilted, the tilt of the box 6a is reduced. The tilt angle is displayed on the digital display section 6b.

The inclination angle sensor is a sensor that captures the change in the inclination of the liquid surface in the chamber by capacitance, or the ratio of the area where the movement of the bubble due to the change in the inclination covers the left and right two electrodes. By changing the resistance value, the resistance value is changed, and an electrical output is generated through a bridge circuit connected to the resistance value.

The reflector 7 uses two positioning tools A and A ′ according to this embodiment, and positions the positioning tools A and A ′ at two points where the distance is desired to be measured, and one positioning tool is used. When A is an ultrasonic wave transmitting portion and the other positioning tool A ′ is an ultrasonic wave reflector, it is a portion that actually reflects ultrasonic waves.

The reflection plate 7 is a rectangular plate-shaped plate that is vertically provided on the upper surface of the rear end portion of the upper plate 5 a of the support plate 5. The front surface of the reflection plate 7 is arranged at a right angle to the center line along the length direction of the upper plate body 5a. Further, the distance from the center of the rotating shaft 4 to the front surface of the reflection plate 7 and the distance from the center of the rotating shaft 4 to the rear end surface of the electronics measure 1 are arranged to be equal.

This is because the electronics measure 1 is designed to measure the distance from the rear end face of the electronics major 1 to the reflector in the normal case, but the upper plate 5a is provided with the elongated hole 5c. This is because the electronics measure 1 is away from the rotation axis 4 which is the standard for alignment. That is, by arranging the reflection plate 7 rearward by a distance away from the rotation axis 4 by the electronics measure 1, it is attempted to subtract the distance away from the rotation axis 4 from the electronics measure 1 from the measurement value to zero. It is a thing.

A through hole 7 a is formed in the reflection plate 7, and a line connecting the through hole 7 a and the projection 1 c on the upper surface of the electronic measure 1 is parallel to the ultrasonic wave emitting direction of the electronic measure 1. It has become. Then, under such a structure, the operator can see the position of the projection 1c and the position of the front reflector overlapping each other through the through hole 7a from the rear side of the reflection plate 7 so that the operator can see the support plate. The directions of ultrasonic waves can be adjusted by adjusting the directions of 5.

Next, a method of using the positioning tool A will be described. First, as shown in FIG. 4, when the distance between the two landmarks is measured by using the two positioning tools A and A ′, first, the tripod 2 is set on the landmark B, respectively. .. Then, the position of the tripod 2 is shifted so that the center of the boundary mark B can be seen from above the rotary shaft 4 through the through hole 4a of the rotary shaft 4. Then, the supporting plate 5 is rotated together with the rotating shaft 4 so that the positioning tools A and A ′ facing the protrusions 1c can be seen from the through holes 7a of the respective reflecting plates 7 so as to overlap with each other. adjust .

Then, the electronic measure 1 of the one positioning tool A is operated to measure the distance between the two boundary markers B. Next, when measuring the distance from one boundary mark B to a position different from the other boundary mark B, one positioning tool is left as it is and the other positioning tool A'or a plate to be a reflector. The body is placed at the different position, and the direction of the electronics measure 1 of the one positioning tool A is adjusted by rotating the support plate 5 together with the rotation shaft 4.

At this time, since the support plate 5 is rotated around the rotation axis 4 which serves as a standard for alignment of the positioning tool A, the support plate 5 is rotated to rotate the support plate 5 from the boundary mark B to the electronic tape measure 1. There is no deviation.

When the measurement is performed on the horizontal ground, the not-shown recess of the shaft 4c is engaged with the not-shown engaging portion of the fitting hole 5e of the projecting portion 5d in advance so as to support the support plate. The tripod 2 is installed while the support plate 5 is horizontal while the 5 is fixed at a right angle to the rotation axis 4 while watching the electronics angle meter 6. Further, when measuring the distance between two points by using the positioning tool A at one point and disposing the reflection plate at the other point, the distance x (see FIG. (Shown inside) to give the distance between the two points.

Next, when measuring the distance between two points across a sloping ground as shown in FIG. 5, positioning tools A and A ′ are installed at the respective points as in the case described above. To do. Then, the support plate 5 is rotated to the left or right around the rotation shaft 4, and the support plate 5 is rotated up or down about the shaft 4c of the rotation shaft 4 so that both support plates 5 are rotated relative to each other. Make them face each other. Then, as described above, the distance m between the two positioning tools A and A ′ is measured as described above, and the angle θ of the electronics measure 1 at this time is measured by the electronics goniometer 6.

From the distance m and the angle θ, the height H and the horizontal distance L can be easily obtained from the following equations. H = m * sin θ, L = m * cos θ In this case, the heights h1 and h2 of the positioning tools A and A ′ are equal.

As described above, according to the positioning tool A of the electronics measure 1 of the present embodiment, the position of the electronics measure 1 can be accurately aligned with the marking provided on the ground such as the boundary mark B. .. The electronics measurer 1 is aligned so that the rotation axis 4 is directly above the marking on the ground, so that even if the measuring direction from the marking is changed, the electronics measure 1 does not shift from the marking. , It is not necessary to readjust the position of the tripod 2.

In addition, when measuring the distance between two points on a sloping ground, the inclination angle between the two points can be easily measured by the electronics goniometer 6, so that the distance between the two points and the inclination angle can be measured. Therefore, the horizontal distance between the two points and the height difference between the two points can be easily obtained.

Note that the positioning tool of the present invention is not limited to the above-mentioned embodiment, and the specific constitutional requirements such as the shape, size, and material of each member can be appropriately changed in practice. In addition, in the above-mentioned embodiment, the distance between two points was mainly measured by using the two positioning tools A and A ′. However, the positioning tool A ′ used as the reflector is provided with the reflection plate. It doesn't matter what you get. For example, a rectangular plate may be used. At this time, it is necessary to add the distance x between the rotation axis 4 of the positioning tool A and the rear end surface of the electronics measure 1 to the distance measured as described above.

Further, as shown in FIG. 6, the weight 10 connected to the chain 10 a from the lower surface of the base 3 of the tripod 2 may be lowered. By doing this, it is possible to confirm this if the position is displaced during measurement.
