BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting member of a reflector device for an optical distance meter having different offset values.

[0002]

2. Description of the Related Art Conventionally, in a reflector device used for measuring a distance between two points by a modulated light wave, a vertical direction passing through a virtual reflecting surface of a corner cube type prism used in the reflector device and a measured point. A type in which the line matches (this is called prism constant 0) and a type in which the vertical line passing through the virtual reflection surface and the measured point is displaced by ε (this is called prism constant ε; ε = −30 m
In contrast to this, even in the light wave rangefinder that generates a modulated light wave, there is an offset mechanism that corrects the measured distance data by the prism constant ε. A prism constant corresponding to the type of the reflector device was set in the offset mechanism and used. This set value is called an offset value.

[0003]

By the way, since the offset mechanism is generally provided inside the optical distance meter, it is extremely troublesome to reset the offset mechanism for each type of the reflector device. However, it has been demanded to be compatible with an optical distance meter in which a predetermined offset value is set by the setting on the support member side that supports the reflector device corresponding to this. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a support member for a reflector device that can easily correspond to any of the optical rangefinders having different offset values. To provide.

In order to achieve the above-mentioned object, according to the present invention, there is provided a support member of a reflector device for an optical distance meter having different offset values, the support member being a reflector device. A through-hole for fixing the first surveying pole mounted thereon, a fixing portion for fixing the second surveying pole at a position in front of the through-hole and separated by a distance corresponding to the offset value, and the through-hole. It is characterized in that a projecting part which is orthogonal to a line connecting the fixing part and the fixing part and which projects to the left and right on a line passing through the center of the through hole is integrally formed. Further, through holes formed by fixing the first surveying pole and the second surveying pole mounted on the support member configured as described above respectively through a distance corresponding to the offset value are formed. It is characterized in that the formed spacing member is attached.

[0005]

The operation of the present invention will be described below with reference to FIG. When the offset value is set to 0, the offset value is set to 0 by placing the lower apex 10a of the first survey pole 10 on which the reflector device 1 is mounted at the measured point. It is possible to accurately perform surveying with the lightwave range finder set to. On the other hand, when used for an optical distance meter whose offset value is set to ε, the reflector in a state in which the first survey pole 10 with the reflector device 1 attached is penetrated through the through hole 21 of the support member 20. The aiming projection 9a of the device 1,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. First, the configuration of the reflector device 1 according to the embodiment will be described with reference to FIG. FIG. 2 is a perspective view showing the relationship between the reflector device 1 and the support member 20 according to the embodiment. In the figure, a reflector device 1
Has a support base 2 for swingably supporting a prism storage member 4 for storing a prism 5 of a corner cube type via an arm 3, and a vertical through hole through which the first survey pole 10 penetrates. 7, a locking screw 8 for pressing and locking the first surveying pole 10 penetrating the vertical through hole 7 from the rear side, and a bubble tube for knowing whether or not the reflector device 1 is installed vertically. 6 are provided. Also,
The prism housing member 4 is attachable to and detachable from the arm 3 by screwing a male screw portion (not shown) formed at the rear end thereof into a female screw portion (not shown) formed at the center of the front surface of the arm 3. Can be attached to the arm 3, while the arm 3
Is formed in a U shape and is swingably attached to the support base 2 with a fixing screw that also serves as aiming protrusions 9a and 9b with both sides sandwiched between the left and right sides of the support base 2. In addition, the aiming protrusions 9a and 9b formed in a conical shape are aligned with the horizontal standard line of the optical wave surveying instrument, so that the modulated optical wave emitted from the optical wave surveying instrument is always directed toward the center of the prism 5. Can be irradiated.

In the reflector device 1 configured as described above, the virtual reflection surface of the prism 5 is the vertical through hole 7
About the center, to be exact, the first through the upper and lower through holes 7.
It is a surface that passes through the center of the surveying pole 10, and a line that connects the sighting projections 9a and 9b is also included in this surface. Therefore, in the reflector device 1 according to the present embodiment, since the virtual reflecting surface of the prism 5 passes through the center of the first survey pole 10, its prism constant is 0, and therefore the offset value is 0. When measuring a distance using an optical wave survey meter set to, the lower apex 1 of the first survey pole 10 with the reflector device 1 attached
By placing 0a at the measured point, it becomes possible to measure the distance accurately.

On the other hand, when the distance is measured using an optical wave surveying instrument whose offset value is set to ε, the supporting member 20 is used. Here, the configuration of the support member 20 will be described with reference to FIG. FIG. 3 is a plan view (A), a sectional view (B), and a rear view (C) of the support member 20. In the figure, the support member 20 is formed in a substantially triangular planar shape, and has a through hole 21 through which the first surveying pole 10 passes vertically and a distance in front of the through hole 21 and corresponding to an offset value ε. Second survey pole 1 at a distance
1 (or 12) is screwed into the fixing screw hole 25 and a line L1 that is orthogonal to the line L1 connecting the through hole 21 and the fixing screw hole 25 and protrudes left and right on a line L2 passing through the center of the through hole 21. The protrusions 27a and 27b are integrally formed of an aluminum alloy (of course, other materials such as hard synthetic resin or brass may be used for molding).
A locking screw hole 22 is exposed from the side in the through hole 21,
The support member 20 can be locked at a predetermined position of the first survey pole 10 by screwing the locking screw 23 into the locking screw hole 22. In addition, in order to prevent the locking screw 23 from falling off, a locking screw 24 (not shown) is screwed downward from the center of the locking screw hole 22.
Are formed. Further, as shown in FIG. 3C, cavities 26a and 26b are formed on the back surface of the support member 20 in order to reduce the weight, reduce the cost, and ensure the precision during molding.

When using the support member 20 having the above-described structure, as shown in FIG. 2, the first survey pole 10 having the reflector device 1 mounted thereon is inserted into the through hole 21 of the support member 20. In this state, as shown in FIG. 5, the aiming projections 9a and 9b of the reflector device 1 and the support member 20 are provided.
The projecting portions 27a and 27b of the above are aligned with each other and locked by the locking screw 23, while the second survey pole 12 is screwed into the fixing screw hole 25 formed at the front side apart from the through hole 21 by the distance ε. By placing the lower apex 12a of the second survey pole 12 at the measured point, the reflector device 1 having a prism constant of 0 can be positioned backward by the same distance as the offset value ε, so that the offset value becomes ε. It is possible to perform the surveying in the set lightwave rangefinder extremely easily and accurately without changing and setting the offset value. The aiming protrusions 9a, 9b of the reflector device 1
By making the protrusions 27a and 27b of the support member 20 coincide with each other, the backward movement of the distance ε with respect to the irradiation direction of the optical survey instrument can be accurately maintained.

By the way, in the embodiment shown in FIG.
Since the case where the reflector device 1 is installed at a low position and the distance is measured is illustrated, the second survey pole 12 is short, but when the reflector device 1 is installed at a high position, the sighting of the reflector device 1 is performed. Projections 9a, 9
Since it is necessary to align b with the protrusions 27a and 27b of the support member 20, the reflector device 1 and the support member 20 cannot be mounted so apart from each other. In this case, as shown in FIG. It is necessary to attach the second survey pole 11 having a long length to the fixing screw hole 25 of. In such a case, the distance between the first survey pole 10 to which the reflector device 1 is attached and the second survey pole 11 may not be accurate, so that the first survey pole 10 mounted on the support member 20 and Set the second survey pole 11 to the interval ε
The distance maintaining member 30 that holds the reflector device 1 is installed below the support member 20 to hold the reflector device 1 with respect to the measured point.
This ensures accurate surveying even when the position is high.

The structure of the spacing member 30 will be described with reference to FIG. FIG. 4 is a plan view (A), a sectional view (B), and a rear view (C) of the spacing member 30. In the figure, the spacing member 30 is formed in a rectangular parallelepiped rod shape, penetrates the first surveying pole 10 and the second surveying pole 11 and is separated from each other by a distance corresponding to the offset value ε. The first through hole 31 and the second through hole 32 to be formed are formed. First through hole 3
The first and second through holes 32 are respectively provided with locking screw holes 33 and 34 from the sides, and the locking screws 35 and 36 are screwed into the locking screw holes 33 and 34, respectively. The spacing member 30 can be locked at a predetermined position (horizontal position) of 10 and the second survey pole 11. In addition, in order to prevent the locking screws 35 and 36 from falling off, the locking screw holes 33 and 34 are attached with locking screws (not shown) downward from the center of the locking screw holes 37 and 38.
Are formed. Further, as shown in FIG. 4C, a cavity 39 is formed on the back surface of the spacing member 30 in order to reduce the weight, reduce the cost, and ensure the precision during molding.

However, by using the spacing member 30 constructed as described above, even when the second survey pole 11 having a long length is mounted on the support member 20, it is mounted on the support member 20. Since the first surveying pole 10 and the second surveying pole 11 can be held at a distance of ε, accurate surveying can be ensured even if the reflector device 1 is located higher than the measured point. . If the first surveying pole 10 and the second surveying pole 11 are further lengthened, the plurality of spacing members 30 may be attached to both poles 10, 11.
You may attach it in between.

The structure of the supporting member 20 of the reflector device 1 for an optical distance meter according to the embodiment has been described above. However, according to the present embodiment, a distance measuring device having an offset value of ε is used. When using, the 1st survey pole 10 with which the reflector apparatus 1 was mounted is attached to the support member 2

Aiming protrusions 9a, 9b and the protrusion 27 of the support member 20
a and 27b are aligned and locked by a locking screw 23, while the second surveying pole 11 is screwed into a fixing screw hole 25 formed in the front which is separated from the through hole 21 by a distance ε. By placing the lower apex 11a of the two surveying poles 11 at the point to be measured, it is possible to accurately perform surveying in the lightwave rangefinder whose offset value is set to ε. Further, when the second survey pole 11 having a long length is mounted on the support member 20, the distance between the first survey pole 10 and the second survey pole 11 mounted on the support member 20 is maintained at a distance ε. By mounting the holding member 30 below the support member 20, accurate surveying can be ensured even if the reflector device 1 is located at a high position with respect to the measured point.

In the above embodiment, the supporting member 20 is used.
Although the triangular shape is shown as above, the shape is not limited to this, and any shape may be used as long as the through hole 21, the fixing screw hole 25, and the protruding portions 27a and 27b are formed. May be. Similarly, the spacing member 30 also has the first through hole 3
Any shape and structure may be used as long as the first and second through holes 32 are formed. Further, the structure of the fixing portion for fixing the second survey pole does not have to be the fixing screw hole type, for example, a structure in which the second survey pole is locked with a locking screw from the side by using a through hole type. May be Also,
It is desirable that the surface of the support member 20 be stamped and displayed with an offset value.

[0015]

As is apparent from the above description, according to the present invention, when the present invention is applied to an optical distance meter having an offset value set to 0, the first reflector equipped with a reflector device is used. By placing the lower apex of the survey pole at the point to be measured, it is possible to accurately perform the survey in the lightwave rangefinder with the offset value set to 0, while the lightwave rangefinder with the offset value set to ε When used with, the sighting protrusion of the reflector device and the protrusion of the support member are aligned and locked with the first surveying pole with the reflector device inserted in the through hole of the support member. At the same time, the second surveying pole is fixed to the fixed portion formed at a distance ε from the through hole, and the lower apex of the second surveying pole is placed at the measured point. Measurements on optical distance meter which is set can also be performed accurately. That is, it is possible to easily and immediately respond to any of the lightwave rangefinders to which different offset values are set. When a long second survey pole is attached to the support member and used, the first survey pole and the second survey pole attached to the support member are used.
By mounting a spacing member that holds the surveying pole at a distance of ε under the support member, accurate surveying can be ensured even if the reflector device is located higher than the surveyed point.
