Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a surveying instrument support device and a surveying device.

[0002]

[Prior art]

 As one type of surveying instrument, level and transit have been well known. These surveying instruments are usually used by setting the surveying instrument on a tripod stand. The tripod stand has a certain large triangle bottom area and is stably erected.

[0003] However, this conventional surveying instrument always has to carry a heavy tripod base, and places a great physical burden on surveying operators.

[0004] Furthermore, in an actual surveying site, it is not always possible to always secure the bottom area of the tripod mount in an area required for stable standing. For example, when conducting surveying in a narrow place indoors in a house or building under construction, it often occurs that it is difficult to secure a bottom area necessary for stable standing of a tripod stand. In such a case, conventionally, there has been no alternative but to reduce the bottom area of the tripod stand and perform surveying in an unstable standing state. For this reason, in some cases, a survey error occurred.

[0005]

[Problems to be solved by the invention]

 An object of the present invention is to provide a surveying instrument supporting device and a surveying device which are highly portable and can be stably supported even in a small place.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a surveying instrument support device (hereinafter, referred to as a support device) according to the present invention includes a bottom plate, first to fourth side plates, and an opening.

The bottom plate has a rectangular shape as a whole, and has a mounting hole in a plane. The first to fourth side plates are erected on four sides of the bottom plate, respectively, and constitute an internal space inside. The opening is located at a position facing the bottom plate.

[0008] The support device according to the present invention is combined with a surveying instrument to constitute a surveying device. In a combination of the surveying instrument with the supporting device, the surveying instrument is housed in the internal space of the supporting device.

[0009] Since the support device according to the present invention includes the opening, the surveying instrument can be stored in the internal space of the support device through the opening.

[0010] Since the opening is located at a position facing the bottom plate, the surveying instrument housed in the internal space is supported by the bottom plate. Since the bottom plate has a mounting hole in the plane, the surveying instrument can be fixed to the bottom plate using the mounting hole.

In this way, since the surveying device can be configured with the surveying instrument incorporated in the support device, a surveying device excellent in portability can be obtained.

The bottom plate has a rectangular shape as a whole, and the first to fourth side plates are erected on four sides of the bottom plate, respectively. Therefore, the first to fourth side plates constitute an orthogonal reference plane in which adjacent ones intersect at substantially right angles. Therefore, for example, two adjacent surfaces of the first to fourth side plates of the support device are brought into contact with a portion where the wall surfaces intersect at right angles to determine the position, and the survey can be performed in this state. Unlike a conventional surveying instrument that has had to use a tripod mount, a space for stably installing the tripod mount is not required, and a vertical reference plane such as a wall surface may be used. Therefore, even in a narrow place, the wall can be stably supported by using the wall surface.

The mounting hole 20 is provided substantially at the center of the bottom plate 10. The mounting hole 20 is used as a hole for mounting and fixing a surveying instrument. The mounting hole 20 may be a circular hole or a square hole. Further, it may be a screw hole.

The first to fourth side plates 11 to 14 are respectively erected on four sides of the bottom plate 10, and constitute an internal space 16 inside. Since the bottom plate 10 is rectangular, the first to fourth side plates 11 to 14 have a rectangular tube shape in which adjacent face plates are orthogonal to each other. Therefore, the two adjacent side plates, namely, the first side plate 11 and the second side plate 12, the second side plate 12 and the third side plate 13, the third side plate 13 and the fourth side plate 13 The side plate 14, the fourth side plate 14, and the first side plate 11 are orthogonal to each other.

The first to fourth side plates 11 to 14 have finger holes 21 to 24 at substantially central portions, respectively. The hole diameter of these finger holes 21 to 24 is arbitrary, and the mouth shape is not limited to a circle but may be a square. The number is also arbitrary, and a plurality of long holes may be formed at intervals in each of the first to fourth side plates 11 to 14. Further, a handle may be attached to the first to fourth side plates 11 to 14.

The opening 15 is located at a position facing the bottom plate 10. More specifically, it forms the same spatial plane as bottom plate 10.

In the illustrated embodiment, a total of four straps 31 to 34 are provided inside each of the intersections of the first to fourth side plates 11 to 14 in a bridging manner to two adjacent side plates. It is provided.

The bottom plate 10 and the first to fourth side plates 11 to 14 are formed into a predetermined shape by press bending of a thin metal plate or plastic molding.
