BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying pole holder.

[0002]

2. Description of the Related Art Japanese Patent Application No. 2-4 previously filed by the applicant of the present application
The support leg of the surveying pole according to 02283 forms a gate-shaped support leg by connecting the upper ends of the leg rods to both ends of the horizontal rod in a foldable manner, and uses a pole gripping tool for holding the surveying pole. The horizontal rod is connected via a retractable fine adjustment device, and the surveying pole set up according to the measurement point is vertically installed by vertically expanding and contracting the fine adjustment device.

[0003]

[Problems to be Solved by the Invention] Two leg rods foldably connected to both ends of a horizontal rod have a constant length, and a polling tool fixed to a fine adjustment device is used for surveying. Depending on the terrain and structures, the legs may not be in contact with the ground because they are held, and even if the surveying pole is installed upright at a corner according to the measuring point, it will be forced to move and rebuild again. Requires that.

Further, due to obstacles such as soft ground, unevenness, and weeds, the ground contact point of the supporting leg may be wrong and the gripping tool may not reach the surveying poll.

[0005]

Means for Solving the Problems A screw hole is provided in one holding piece of a pinch-shaped holding tool for holding a surveying pole, and a long hole is formed in one surface of an L-shaped plate and a through hole is formed in the other surface. Forming a connecting member provided respectively, one side of the connecting member is connected to one of the gripping pieces of the gripper so as to be capable of being tilted up and down, and a locking screw is inserted into a long hole provided in the connecting member, and Securely connect the connecting member to the connecting member by sliding it over the screw hole provided on one surface of the connecting member, and slidably cover the connecting rod on the long rod and connect the upper end of the short rod to the connecting rod with the thumbscrew. At the same time, the lower ends of the long rod and the short rod are respectively connected to the connecting rods which are bent downward at both ends to form a ridge, and a supporting leg is formed, and a screw hole provided on the other surface of the connecting member and the connecting member. Attach the adjustment bolt to the through hole provided on the other surface, and operate the adjustment bolt located between the screw hole and the through hole. Sticking to, and, which is inserted the upper end of the long rod connecting, regardless of terrain and structures, surveying port - aims to make the rigidly stations Le.

[0006]

The surveying poll is temporarily erected with its tip aligned with the measuring point, and the connecting member is raised and lowered according to the terrain, or the connecting member is slid back and forth by operating the knob.

Further, the long rod which constitutes the supporting leg is rocked to the left and right, and the connecting rod which connects the short rod is slid up and down along the long rod so as to be connected to the lower ends of the long rod and the short rod. Ground the butt of the ground to the ground surface.

After the surveying poll was erected vertically at the measuring point,
The thumbscrew that fixes the connecting member to the grip is tightened to fix the connecting member, the connecting member, and the supporting leg.

[0009]

EXAMPLE As shown in FIGS. 1 and 2, a surveying poll 1
A screw hole 2c is provided in one gripping piece 2b of the pinch-shaped gripping tool 2 for sandwiching between the arc-shaped crimping portion 2a.

The connecting member 3 is formed by providing the through hole 3c and the screw hole 3b on one surface of the L-shaped plate and the screw hole 3c on the other surface thereof.

The connection member 3 is connected to the gripper 2 by means of a thumbscrew 4 so as to be able to move up and down.

A long hole 5a is provided on one surface of the L-shaped plate and a through hole 5b is provided on the other surface to form a connecting member 5. The locking screw 6 is inserted into the long hole 5a, and the connecting member 3 The connecting member 5 is slidably connected to the connecting member 3 by being fixed to the screw hole 3b provided on one surface.

A rectangular plate member is bent to provide a circular holding portion 7a and an overlapping portion 7b, and a screw hole 7c is provided in the overlapping portion 7b to form the connecting fitting 7.

A long rod 8 made of a round pipe is slidably covered with a holding portion 5a of a connecting fitting 7, and an upper end of a short rod 9 made of a round pipe is connected to an overlapping portion 7b of the connecting fitting 7 with a thumbscrew 10. To do.

The lower ends of the long rods 8 and the short rods 9 are pivotally attached to the U-shaped connecting fittings 12 fixed to the both ends of the connecting rod 11 in which both ends are bent downward to form the stone protrusions 11a, and the supporting legs are supported. 13 is formed.

A screw hole 3c provided on the other surface of the connecting member 3,
The adjusting bolt 14 is attached to the through hole 5b provided on the other surface of the connecting member 7, and the operating knob 15 is fixed to the adjusting bolt 14 located between the screw hole 3c and the through hole 5b. The upper end of 8 is inserted and connected.

3 to 6 show a use state of the present invention. FIG. 3 shows the case where the corner of the retaining wall 16 is a measuring point, the surveying poll 1 is aligned with the measuring point, and the supporting leg 13 is attached. It shows a state in which the connecting member 3 is tilted, the connecting member 5 is slid as necessary to stand on the ground surface behind the retaining wall 16, and the surveying poll 1 is supported vertically.

In FIGS. 4 and 5, when there is a measuring point in the middle of the slope 17, the gripping tool 2 is moved to align the surveying poll 1 with the measuring point, and the supporting leg 13 is positioned more than the measuring point. Upper slope 17
2 shows a state in which the surveying poll 1 is erected vertically at the measuring point by tilting the connecting member 3 and sliding the connecting member 7, and the thumbscrew 4 is tightened and fixed. In this case, the range of 360 degrees around the measurement point is the grounding range of the support leg 13.

Further, the connecting metal fitting 7 held by the long rod 8 is slid on the long rod 8 so that the butt 11a can be stably stood on the inclined surface.

FIG. 6 shows that when the survey point is in the entering corner or the exit corner, the supporting leg 13 is erected in front of the measuring point, and the supporting leg 13 is used to measure the polling pole 1.
Shows the state of standing upright in accordance with the measurement point.

[0021]

[Effect of the Invention] The movable range of the support leg 13 around the surveying poll 1 is widened, and the grip 2 is located in the surveying poll.
The distance that can be connected to the poll 1 is also long, and therefore the surveying poll 1 is set up vertically at the survey point without being hindered by uneven terrain, soft ground, or obstacles such as weeds. The surveying poll 1 and the support leg 13 can be fixed by tightening the 10 to firmly stand.

Further, since the grounding points of the supporting leg 13 are two points and can be set up on the line, it is easy to select the grounding place of the supporting leg 13 and move after positioning and grounding the supporting leg 13. The survey work can be done quickly without the need.
