2. Description of the Related Art Conventionally, when a distance to a wall is measured by using a reflector for measuring the distance between two points using a modulated light wave, the wall must be located at a position of a virtual reflection surface. However, the distance could not be measured with the reflector mounted on the support. For this reason, conventionally, as shown in FIG. 5, the reflector 6 is removed from the support base 2, and the male screw 6a of the reflector 6 has a conical wall surface survey that matches the distance to the virtual reflection surface L1 of the reflector 6. Screw the auxiliary tool 23,
As shown in FIG. 6, the reflector 6 was brought into contact with the wall surface while the wall surface survey aid 23 was attached to measure the distance.

[0003]

Therefore, in order to measure the distance to the wall surface, it is necessary to remove the reflector 6 from the support base 2 and attach the wall measuring aid 23 to the male screw 6a of the reflector 6. This is extremely troublesome, and has the disadvantage that the wall surface survey aid 23 must be managed so as not to be lost. The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a lightwave distance meter reflector support base that allows anyone to easily and quickly measure an accurate distance to a wall surface. is there.

[0004]

Means adopted by the present invention to achieve the above object will be described with reference to FIGS. 1 to 6. Referring to FIGS. 1 to 6, upper and lower through holes through which a columnar surveying support 4 penetrates. 7, a bubble tube 9 provided on the rear upper surface orthogonal to the upper and lower through holes 7, and a virtual reflection surface L of the reflector 6.
1. A support table 2 integrally provided with a mounting swing table 3 which is swingably provided around a center 1 and a reflector 6 can be mounted on a front surface thereof, wherein the virtual reflection surface L1 and the support By forming the length D up to the rear end 24 of the table 2 to be an integer value, when the object to be measured is the wall surface 27, the reflector 6 is detached from the support table 2 as in the related art, and the wall surface is removed. Without attaching the measuring aid 23, the distance is measured by applying the rear end 24 to the wall surface 27 with the reflector 6 attached to the support base 2, and then adding an integer value to the measured distance to obtain an accurate distance. This is advantageous in that the distance to the wall surface can be measured simply and quickly.

As shown in FIG. 4, when the support base 2 is bent at right angles to the mounting swing base 3 in a direction in which the bottom surface 26 faces outward, the virtual reflection surface L1 and the bottom surface are bent. By forming the length d up to the portion 26 to be an integer value, when the object to be measured is the wall surface 27, the reflector 6 is detached from the support base 2 and the wall measurement auxiliary tool 23 is removed. Without mounting, the reflector 6 was left attached to the support table 2 and the support table 2 was bent at right angles to the mounting swing table 3, and the bottom portion 26 was pressed against the wall surface 27 to measure the distance, and then the measurement was performed. If an integer value is added to the distance, the distance becomes accurate, and it is advantageous in that the distance to the wall surface can be measured easily and quickly. In this case, the bottom surface portion 26 is
Forming a flat surface so as to make a surface contact when brought into contact with the substrate has an advantage that a measurement error of the distance to the wall surface 27 is reduced as compared with a case where the line contact is made.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show the entirety of a lightwave distance meter reflector 1 according to the embodiment, and FIG.
FIG. 2 is a plan view of the lightwave distance meter reflector 1, FIG. 2 is a sectional view of an upper portion of the lightwave distance meter reflector 1, and FIG. 3 is a perspective view of the lightwave distance meter reflector 1.

In the figure, a lightwave distance meter reflector 1
Is a support 2 for supporting the reflector 6, and the support 2
And a pedestal 5 mounted on the lower end of the surveying column 4 and supporting the entire lightwave distance meter reflector-1.

First, a support table 2 for supporting the reflector 6
Will be described. The support base 2 includes an upper and lower through hole 7 through which the columnar surveying support column 4 penetrates, a bubble tube 9 provided on a rear upper surface orthogonal to the upper and lower through hole 7, and a virtual reflection surface L1 of the reflector 6. A swing center 3 is provided at the center so as to be swingable, and a reflector 6 can be mounted on the front surface thereof.

The upper and lower through holes 7 are formed as shown in FIG.
It is formed in the front part of the support base 2, and the shape of one side surface is formed in a triangular shape with the virtual reflection surface L1 as a bisector, and the other side surface is formed in a substantially square shape. The hole is slightly larger than the diameter of the column 4. A fastening screw 18, which will be described later, is screwed into the other side surface. By tightening the fastening screw 18, the surveying support 4 inserted into the upper and lower through holes 7 is triangulated on one side surface. The state is brought into contact with the shape side surfaces 7a and 7b. In this state, the support 2 having the reflector 6 is fixed to the surveying column 4. At this time, even if the diameters of the surveying columns 4 are different, the center of the surveying columns 4 is always located on the virtual reflection surface L1 in a fixed state, so that an accurate distance can always be measured. .

The bubble tube 9 is accommodated in a bubble tube accommodating chamber 8 formed in a columnar recess at the rear portion of the support table 2. The bubble tube 9 is provided with air bubbles in a plastic container. Is formed. Thereby, even if the bubble tube 9 is inserted too much when the pointed surveying support 4 is inserted into the upper and lower through holes 7, there is an advantage that it is not broken unlike a conventional glass bubble tube. There is.

The bubble tube 9 has a bubble tube support base 10 adhered to the lower portion thereof, and the integrated bubble tube 9 is inserted from above the bubble tube accommodating chamber 8 to surround the upper portion thereof. By inserting the O-ring 14, it is mounted so as not to be pulled out. The O-ring 14 fits into a fitting groove formed inside the upper part of the bubble tube accommodating chamber 8. The bubble tube support 10 has a fulcrum hole 12 formed at the center of the bottom surface thereof. The fulcrum hole 12 is placed on a fulcrum protrusion 11 protruding from the center of the bottom surface of the bubble tube accommodating chamber 8. It is inclined in either direction. Thus, a plurality of adjusting screws 13 (two screws are drawn in the drawing, inserted in the bubble tube supporting base 10 from the back of the supporting base 2, but actually three screws are formed in a triangular shape). Are arranged). For this reason,
By adjusting these three adjusting screws 13, the inclination of the bubble tube support base 10 and the bubble tube 9 adhered thereto can be adjusted, so that the bubbles in the bubble tube 9 are positioned at the center in a horizontal state. Can be adjusted.

Further, the rear portion of the support base 2 is formed in a columnar overall shape for accommodating the above-described bubble tube 9, and the rear end portion 24 of the columnar shape and the virtual reflection surface L are formed.
The length D up to 1 is designed to be an integer value.
In the case of this embodiment, it is designed to be 35 mm. This is for the following reasons.

That is, when the object to be measured is a wall surface, the wall surface must be located at the position of the virtual reflection surface L1, so that the distance can be measured while the reflector 6 is mounted on the support base 2. could not. For this reason, conventionally, the reflector 6 is detached from the support base 2 and, as shown in FIG. As shown in FIG. 6, the auxiliary tool 23 was screwed on, and the reflector 6 was brought into contact with the wall surface in a state where the wall surveying auxiliary tool 23 was attached to measure the distance.
For this reason, when measuring the distance to the wall surface, the work of removing the reflector 6 from the support 2 and the reflector 6
The operation of attaching the wall surveying auxiliary tool 23 to the male screw 6a is necessary, which is extremely troublesome.
3 had to be managed so as not to be lost.

On the other hand, when the length D between the virtual reflecting surface L1 and the rear end portion 24 is an integer value as in this embodiment, the surveying column 24 is detached from the support 2 (case Depending on the case, the rear end 2
4 is brought into contact with the wall surface 27 (see the wall surface 27 in FIG. 4) to measure the distance, and an integer value can be added to the measured value, so that anyone can easily and quickly measure the accurate distance to the wall surface. can do.

At the front of the support table 2, a mounting swing table 3 is swingably provided. Specifically, both sides of the mounting swing table 3 formed in a U-shape are positioned so as to sandwich the side surface of the support table 2, and one side piece is mounted on the mounting table fixing screw 16.
By screwing the other side piece with the fastening screw 18, the mounting swing base 3 is pivotally supported on the support base 2 so as to be vertically swingable. Also, at the front center of the mounting swing base 3,
A reflector connecting screw portion 15 in which a female screw is formed is formed, and a male screw 6 a formed at the rear end of the reflector 6 is screwed to the connecting screw portion 15, so that the reflector 6 is moved via the mounting swing base 3. And is swingably supported by the support base 2. By the way, the mounting base fixing screw 16 and the fastening screw 18 are formed such that the tip portions thereof are formed as conical horizontal indicating vertices 19, and a straight line connecting the horizontal indicating vertices 19 indicates the swing center. The swing center line is designed to be included in a virtual reflection surface L1 described later in detail.
Also, by making the line connecting the conical horizontal pointing apex 19 coincide with the standard line of the telescope provided on the side of the modulated light source, the modulated light can be always emitted toward the center of the reflector 6.

The mounting base fixing screw 16 penetrates through the mounting oscillating base 3, and a screw portion (not shown) formed at the end thereof is screwed into the side surface of the support base 2 so that the mounting base is fixed. The moving table 3 is supported and fixed to the supporting table 2, and a washer 17 made of a synthetic resin is attached to the mounting table 3 when mounting the moving table 3.
And a spring washer (not shown)
Is not easily detachable, and the angle is held at the position where the mounting swinging is performed. Therefore, the swinging operation of the mounting swing base 3 is performed by the washer 17 made of the synthetic resin. It is performed by the sliding action. On the other hand, the fastening screw 18 penetrates through the mounting swing base 3 and the threaded portion formed at the tip thereof is screwed into the screw hole formed on the side surface of the support base 2 while being screwed therethrough. A pressing piece 18a made of a synthetic resin adhered to the tip of the threaded portion 18 is pressed against the surveying column 4. Therefore, the swing motion of the mounting swing table 3 is performed by the sliding action of the synthetic resin pressing piece 18a. An E-ring is fitted in the middle of the screw portion of the fastening screw 18 so that the fastening screw 18 does not fall off the mounting swing base 3 by the E-ring.

As described above, the support table 2 includes the mounting swing table 3
When the bottom surface 26 of the support base 2 is bent at a right angle to the direction in which the support base 2 faces outward, the swing center, that is, the virtual reflection surface It is formed so that the length d between L1 and the bottom portion 26 is an integer value. This is based on the same idea as the length D up to the rear end 24. As shown in FIG. 4, the reflector 6 is still attached to the support 2 and the support 2 is attached to the mounting swing base 3. The bottom 26 is bent at a right angle to the wall 27
Then, the distance is measured by adding the integer value to the measured distance, and then the distance becomes accurate, and the distance to the wall surface can be easily and quickly measured. In the case of the present embodiment, the length d is designed to be 15 mm. In addition, when the position of the light source is shifted slightly from the front position of the reflector 6 and is irradiated slightly obliquely, the error is smaller when the bottom surface 26 is in contact with the wall surface 27 than when the rear end 24 is in contact. .

In the middle of the surveying support 4 penetrating through the upper and lower through holes 7 of the support 2, there is formed a step 22 with which the lower end of the support 2 abuts when the support 2 is inserted. A screw portion 20 is formed below the step portion 22, and a lower portion of the screw portion 20 is formed in a conical shape. The pedestal 5 is screwed into the screw portion 20, and a lock nut 21 for fixing the screwed position of the pedestal 5 is also screwed. The pedestal 5 is formed in a three-point supporting bridge shape so that the inside can be visually recognized from the outside.
When attached to the apex, the apex 25 of the conical shape is visible. At this time, it is preferable that the pedestal 5 is screwed into the screw portion 20 so that the position of the vertex 25 becomes a slightly floating position, and the lock nut 21 is fixed at that position to make the vertex 25 coincide with the measurement point.

In the lightwave distance meter reflector 1 formed as described above, the vertex 25 of the surveying column 4 is designed to pass over the virtual reflection surface L1 of the reflector 6, but the virtual reflection surface of the reflector 6 It is not necessarily designed to pass through the intersection P between L1 and the optical axis L2 of the reflector 6. This is because the center (corresponding to the vertex 25) of the surveying support 4 is located at a different position on the virtual reflection surface L1 when the surveying support 4 having a different diameter is inserted into the upper and lower through holes 7. . Thus, the intersection P
Even if the center of the survey support 4 does not coincide with the center of the survey support 4, the intersection P and the center (vertex 25) of the survey support 4 are on the virtual reflection surface L <b> 1, so even when the survey support 4 having a different diameter is used. No error occurs in the distance measurement.

The configuration of the lightwave distance meter reflector 1 according to the embodiment has been described above. According to this embodiment, the vertical through-hole 7 through which the columnar surveying support 4 penetrates is provided.
A bubble tube 9 provided on the rear upper surface orthogonal to the upper and lower through holes 7, and a mounting rocker that is provided so as to be swingable about a virtual reflection surface L <b> 1 of the reflector 6 and can mount the reflector 6 on its front surface. A support table 2 having a moving table 3
And one side surface of the upper and lower through holes 7 is formed in a triangular shape such that the virtual reflection surface L1 becomes a bisector.
By tightening the fastening screw 18 screwed from the other side surface of the upper and lower through holes 7 in a state where the surveying column 4 is penetrated, the surveying column 4 is brought into contact with the two sides of the triangular side surfaces 7a and 7b. , So that the surveying columns 4 with different diameters
Is fixed to the upper and lower through holes 7 with the fastening screws 18, since the center of the surveying column 4 is always located on the virtual reflecting surface L1.
The distance can be measured accurately.

Further, by forming the bubble tube 9 by a transparent plastic container, even if the bubble tube 9 is inserted when the pointed surveying support 4 is inserted into the upper and lower through-holes 7, the conventional method can be used. There is an advantage that the glass tube is not broken unlike the bubble tube made of glass.

The virtual reflecting surface L1 and the support table 2
When the object to be measured is a wall surface, the reflector 6 is detached from the support base 2 as in the related art, so that the length D up to the rear end 24 is an integer value. Without attaching the reflector 23, the rear end portion 24 is pressed against the wall surface 27 while the reflector 6 is attached to the support base 2 to measure the distance, and then an integer value is added to the measured distance to obtain an accurate distance. This is advantageous in that the distance to the wall surface can be quickly measured.

Further, when the support table 2 is bent at right angles to the mounting swing table 3 so that the bottom surface 26 faces outward, the length d between the virtual reflection surface L1 and the bottom surface 26 is d. Is formed to be an integer value, so that when the object to be measured is the wall surface 27, the reflector 6 is removed from the support base 2 without attaching the wall measurement aid 23 as in the related art. Support stand 2
If the support table 2 is bent at right angles to the mounting swing table 3 and the bottom surface 26 is pressed against the wall surface 27 to measure the distance, and then an integer value is added to the measured distance, accurate This is advantageous in that the distance to the wall surface can be easily and quickly measured. In this case, by forming the bottom surface portion 26 in a flat shape so as to make surface contact when brought into contact with the wall surface 27, the measurement error of the distance to the wall surface 27 is reduced as compared with the case of line contact. There is an advantage that it becomes.

In the above-described embodiment, the surveying column 4 fixed to the pedestal 5 has been described.
There is an advantage that distance measurement can be performed very quickly when it is not possible to install the reflector at the distance measurement point mainly using a tripod, or when it can be easily placed on the measuring table, When the pedestal 5 cannot be installed, a long surveying pole can be used by penetrating the upper and lower through holes 7 of the support base 2. Further, it is also possible to use the lower end of the above-mentioned surveying column 4 by screwing it to a tripod.

As is apparent from the above description, according to the present invention, the columnar surveying column is provided on the upper and lower through-holes penetrating therethrough and the rear upper surface perpendicular to the upper and lower through-holes. A support table integrally including a bubble tube and a mounting swing table swingably provided around a virtual reflection surface of a reflector and capable of mounting a reflector on the front surface thereof, wherein the virtual reflection surface and the support When the object to be measured is a wall surface by forming the length to the end of the table to be an integer value, it is necessary to remove the reflector from the support table and attach the wall measurement aid as in the conventional case. Instead, with the reflector attached to the support, press the rear end against the wall to measure the distance, and then
If an integer value is added to the measured distance, an accurate distance is obtained, which is advantageous in that the distance to the wall surface can be easily and quickly measured.

When the support base is bent at right angles to the mounting swing base in a direction in which the bottom surface faces outward,
By forming the length of the virtual reflection surface and the bottom portion to be an integer value, when the object to be measured is a wall surface, the reflector is removed from the support table as in the related art, and the wall measurement auxiliary tool is used.
