1 and 2 are diagrams showing an example of the measuring instrument 1 according to the present embodiment. 1 is a perspective view of the measuring instrument 1, FIG. 2A is a side view showing a state in which the first stage staff 10 of the measuring instrument 1 is standing, and FIG. 2B is a first view of the measuring instrument 1. It is a side view which shows the state which the stage staff 10 has fallen down. The measuring instrument 1 stands on its own with the stage staff standing perpendicular to the ground, and when taking a site-recorded photograph, it is reflected in a photograph such as a reinforcing bar arrangement so that the length such as the interval between the reinforcing bars can be known. Do not use.

The measuring instrument 1 connects a first stage staff 10 having a first surface 11 and a second surface 12 on the opposite side thereof, a pedestal 20 supporting the first stage staff 10, and a first scale 10 and a pedestal 20. The joint portion 30 and the joint portion 30 are provided.

The first stage staff 10 has a rectangular thin plate shape, and has a scale notch on at least one of the first surface 11 and the second surface 12. The first stage staff 10 may be any material as long as it can be processed into a thin plate shape such as aluminum, wood, and plastic resin. In the present embodiment, the first stage staff 10 is graduated every 1 mm on the first surface 11. Further, the first stage staff 10 has a length of 1 m in the present embodiment, but the length is not particularly limited, and may be, for example, 50 cm, 70 cm, or the like.

The pedestal 20 has a thin plate shape and a quadrangular shape. The pedestal 20 is made of a material heavier than the first stage staff 10, and a thin but heavy material such as steel or iron is used. By making the pedestal 20 heavy, the first stage staff 10 in a standing state can stably stand on its own without being blown by the wind.

The pedestal 20 comes into contact with one short side of the first stage staff 10 when the first stage staff 10 stands vertically, and supports the first stage staff 10. Since the first stage staff 10 is connected to the pedestal 20 by a joint portion 30 described later, the end portion of the first stage staff 10 and the pedestal 20 are in contact with each other but are not fixed. Further, the end of the first stage staff 10 and the pedestal 20 may be close to each other without being in contact with each other.

The joint portion 30 connects the first stage staff 10 and the pedestal 20 so as to be able to change between a standing state and a tilted state of the first stage staff 10. The joint portion 30 may have any joint mechanism as long as the first stage staff 10 can be changed between a standing state and a collapsed state.

For example, in the present embodiment, the joint portion 30 has a substantially L-shape composed of two arms 31 and 32, and a reinforcing arm 33 connected to the two arms 31 and 32, a lever 34, and the like. It includes a connecting piece 35 for connecting the reinforcing arm 33. The ends of the two reinforcing arms 33 are connected by a connecting piece 35, and are connected to the arms 31 and 32. The reinforcing arm 33 is fixedly connected to the arm 31 so as to be slidably movable in the rail 311 and rotatably fixed to the arm 32. The rail 311 is provided from the central portion to the end portion of the arm 31. As a result, the connecting piece 35 slides in the rail 311 so that one end of the reinforcing arm 33 can move from the center to the end of the arm 31.

The arm 31 is on the one end side in the longitudinal direction of the first stage staff 10, specifically, the lower end side of the first stage staff 10 (pedestal 20) with the first scale 10 standing perpendicular to the pedestal 20. It is fixed to the side) with screws or the like. The arm 32 is fixed to the flat surface portion of the pedestal 20 with screws or the like.

When the measuring instrument 1 is used, when the end side of the first scale 10 away from the pedestal 20 is raised, the reinforcing arm 33 slides and the arm 31 rises. Since the connecting piece 35 is locked by the lever 34 near the center of the arm 31 and the movement of the reinforcing arm 33 is fixed, the first stage staff 10 is fixed in a standing state. When the lever 34 is pushed to unlock the connecting piece 35, the reinforcing arm 33 slides and the first stage staff 10 can be tilted.

When the measuring instrument 1 is used, the first scale 10 is fixed in a standing state, and when not in use, the first scale 10 can be tilted, so that the measuring instrument 1 can be carried in a compact state. Further, the measuring instrument 1 is self-supporting in a stable state without falling or tilting because the pedestal 20 heavier than the first stage staff acts as a weight when the first stage staff 10 is standing. To do.

The joint portion 30 may be detachably attached to the first stage staff 10 and the pedestal 20. If the joint portion 30 is removable, the first scale 10 can be removed from the joint portion 30 and used as a scale for measuring the length of a material or the like. Of course, since the first scale 10 can be tilted without removing it from the joint portion 30, the first scale 10 can be used as a scale for measuring the length.

The measuring instrument 1 can be used alone or in combination. FIG. 3 is a diagram showing an example of use of the measuring instrument 1 according to the present embodiment. As shown in FIG. 3, the two measuring instruments 1 and the stage staff A can be used in combination.

In this usage example, a cross metal fitting (not shown) is attached to the tip of the first stage staff 10 in a standing state, and the stage staff A is horizontally hung for use. Since the measuring instrument 1 is self-supporting without the support of an operator or the like, it is possible to display not only the length of the vertical plane but also the length of the horizontal plane and whether it is parallel to the ground, etc. Even in the case of, the photography work can be performed efficiently.

According to the measuring instrument 1 of the present embodiment, since the measuring instrument 1 can be stood up without being tilted at the time of taking a field record photograph, it is possible to take a photograph without being affected by wind or the like, and when working alone. Work accuracy and work efficiency can be improved. Further, since the measuring instrument 1 can be in a state where the first stage staff 10 is tilted down, it is easy to carry without being bulky.

FIG. 4 is a diagram showing an example of the measuring instrument 1a according to the modified example of the present embodiment. In this modified example, the second stage staff 40 serves as the pedestal 20 instead of the pedestal 20. Hereinafter, the same configurations as those in the embodiment will be designated by the same reference numerals, the description thereof will be omitted as appropriate, and different parts will be described.

Like the first stage staff 10, the second stage staff 40 has a rectangular thin plate shape, and has a second surface (not shown) of a surface opposite to the first surface 41. The second stage staff 40 has graduations on at least one of the first surface 41 and the second surface. In this modification, a scale is engraved on the first surface 41 every 1 mm. The first stage staff 10 and the second stage staff 40 are connected by a joint portion 30 so that both ends are in contact with or close to each other while the first stage staff 10 is standing.

By providing the measuring instrument 1a with the first stage staff 10 and the second stage staff 40, it can serve as an index of not only the vertical plane but also the length of the horizontal plane. Since it is possible to display with one measuring instrument 1a without preparing a scale corresponding to each of the vertical plane and the horizontal plane, it is possible to easily take a site-recorded photograph even in the case of one-person work.

The measuring instrument 1a may include a magnetic material on the second surface of the first stage staff 10 and / or the second stage staff 40. Since the measuring instrument 1a is firmly self-supporting because it is firmly fixed to the reinforcing bar arrangement or the like, it is possible to take an accurate on-site recorded photograph.

FIG. 5 is a diagram showing an example of the measuring instrument 1b according to another modified example of the present embodiment. In this modification, the measuring instrument 1b does not include the pedestal 20, but includes the level 50 on the second surface 12 of the first stage staff 10.

The first stage staff 10 is provided with a level 50 on the second surface 12. Since the level (level) is a known one, detailed description thereof will be omitted. The level 50 is a rectangular parallelepiped and is attached so that the longitudinal direction is located in the longitudinal direction of the first stage staff 10. In this modification, a spirit level that can inspect whether or not it is horizontal when placed in either the longitudinal direction or the lateral direction is used.

The measuring instrument 1b is provided with a magnetic material (not shown) on the surface of the level 50 opposite to the second surface 12. By providing the magnetic material, the measuring instrument 1b can be attached and fixed to the magnetic material such as the reinforcing bar arrangement, so that an accurate on-site recorded photograph can be easily taken. Further, since the measuring instrument 1b includes a level 50, it is possible to confirm whether or not the measuring instrument 1b is horizontal. Since the first scale 10 includes the level staff 50, the measuring instrument 1b can be easily carried because it is not necessary to prepare the stage staff and the level staff separately. If the lower end surface of the first stage staff 10 and the lower end surface of the level staff 50 are flattened, the measuring instrument 1b can be made independent.
