Description

[Detailed description of the invention] The present invention relates to a collapsible support leg for a measuring pole, in which the upper ends of the leg rods are connected to both ends of the horizontal rod, and a gripping tool for holding the surveying pole set at a surveying point is attached to the side. The gist is that the rod is pivotally attached to the center of the rod so that it can be tilted freely, and if necessary, a locking rod that fixes both leg rods is removably hung across both leg rods, allowing surveying work to be carried out quickly. With the goal.

Conventionally, surveying has been carried out by standing a surveying pole perpendicular to a survey point and supporting the pole with a tripod rod. If the ground is soft, it will rattle, and if the ground is soft, it will take time and effort to push the tips of the legs into the ground. It is time-consuming and difficult to carry out rapid survey work, and depending on the topography of the survey point, it may be impossible to set up a tripod rod.

The present invention eliminates such drawbacks, and its embodiment will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the cross section is formed into a flat convex shape,
A surveying pole 6 is supported by fixing an L-shaped bracket 5 to the side surface of the thick part of the horizontal rod 4, which has elongated holes 2, 2 bored in the thin part 1 and recesses 3, 3 at both ends. A leg rod 9 has a clip-shaped gripping tool 7 pivotably attached to the bracket 5 so as to be freely tiltable and screwed with a wing screw 10, and a thin wall portion 8 overlapping the thin wall portion 1 formed on the horizontal rod 4 is formed at the upper end. , 9 are screwed into the elongated holes 2, 2 of the horizontal rod 4 with wing screws 10, 10, respectively, in a gate shape. Furthermore, a protrusion 11 that engages with the recess 3 is provided protrudingly on the side surface of the step formed at the boundary between the thin part 8 and the base rod, so that the leg rod 9,
9 is expanded in a direction in which it is linearly connected to the horizontal rod 4, and the leg rods 9, 9 are moved in a direction in which they approach each other, so that the recess 3 and the protrusion 11 are engaged with each other, and the thumbscrews 10, 10 are tightened. As shown in FIG. 3, it is shaped like a single rod and can also be used as a measuring pole.
When the locking rod 12 is removably hung on the lower part of the leg rods 9, 9 hinged in a gate shape, the leg rods 9, 9 are firmly fixed. As another example, as shown in FIGS. 4 and 5, a gripping tool 7 provided on the horizontal rod 4
Adjacent to this, another bracket 5' is fixed to the transverse rod 4, and a clip-shaped gripping tool 7' that supports the other leg rod 9' is pivotally pivoted so as to be tiltable, and the thumbscrew 10' Tighten. In addition, 13 in the figure is a boundary stone.

Since the present invention is constructed in this way, when the leg rods 9, 9 fixed in a gate shape to the horizontal rod 4 are held between the measuring points such as the boundary marker 13 and the connecting rod 12 is pressed with the feet, the leg rods 9, 9 The tip of the pole easily pierces the ground, allowing quick positioning of the leg rods 9, 9.Next, the surveying pole 6 is held in the gripping tool 7, the tip of the pole is aligned with the survey point, and then the surveying pole By slightly moving and adjusting the horizontal rod 4 in the horizontal direction so that the pole 6 is erected vertically, the work of erecting the surveying pole 6 is easily and extremely quickly completed, and when the surveying of the survey point is completed,
While holding the surveying pole 6, carry it to the next survey point, push the leg rods 9, 9 into the ground so as to sandwich the survey point, align the tip of the survey pole 6 with the survey point, and then check the verticality of the pole. All you have to do is adjust it. In addition, if the ground surface has elevations and is paved, by tilting the horizontal rod 4 diagonally, it is possible to create a difference in height between the tip positions of the leg rods 9, 9, so that the legs can be placed along the ground surface without wobbling. If the rods 9, 9 can be installed upright, and there is a risk of the two leg rods 9, 9 falling down in the event of strong winds, another gripping device 7' may be used in which the other leg rods 9' are provided on the horizontal rod 4. If the surveying pole 6 is held upright by the tripod rod, there is no risk of the surveying pole 6 falling over and making surveying impossible. When the leg rods 9, 9 are extended in a direction in which they are aligned with the horizontal rod 4 and fixed with thumb screws 10, 10, it can also be used as a surveying pole.

As described above, the present invention has a simple structure, is easy to manufacture, is easy to handle, and is inexpensive.
