Description

[Detailed explanation of the invention] A. Purpose of the invention (industrial application field) The invention is useful in the manufacturing industry of tools used in architecture and civil engineering work, and is convenient because one person can easily set the desired angle. This relates to angle adjusters used for foundation construction, etc.

(Prior art) Conventionally, surveying instruments used to measure angles at construction or surveying sites have, for example, a protractor with a water string attached to its outer diameter that rotates freely around an axis passing through the center, and a protractor with a water string attached to the outer diameter that rotates freely around an axis passing through the center. It is known that the indicator consists of an indicator with a water thread attached to the outer end, which rotates freely regardless of the minutes with this in mind. (Refer to Japanese Utility Model Publication No. 130211/1983) (Problem to be solved by the invention) The above-mentioned invention uses a water thread to rotate the minute and index in the direction of the water thread so that it can be easily and accurately held in hand even in a narrow space. In addition, this angle meter has the effect of being able to directly measure in diagonal directions as well as horizontal and vertical directions, but since this angle meter is configured to be hand-held,
When measuring angles, the other ends of the two water strings are fixed to a spear shape, etc., so it is possible to measure the angle formed by connecting these three points. Conversely, when the angle is set to a certain angle, for example 90°, it is not possible to measure which point in the spear shape is the desired position while moving the other end of one water thread.

Further, if the angle is determined at a far position away from the angle meter, the degree cannot be read from this point, so accurate angle determination cannot be performed.

It had various problems such as.

The present invention was made in order to solve the above-mentioned conventional problems, and an angle setting means is provided on a rotatable angle setting rotary plate with a basic water line, and a separate angle setting means is provided for this angle setting means. A convenient foundation that allows a single worker to easily angle the foundation, etc. at a construction site, by providing a display means that indicates that the set angle has been reached when the angle setting water line comes into contact with it. The purpose is to provide anglers for use in construction work, etc.

B. Structure of the invention (means for solving the problem) The means of the invention for achieving the above-mentioned purpose are: a base supported at a predetermined height by a support leg; and an angle rotatably supported on the base. A turning plate, a basic water line connected to the turning plate, an arcuate groove recessed on the outer circumferential side of the turning plate, and an electrically conductive state between the inside of the arcuate groove and the basic shaft. A current-carrying member is formed between the wiring connected to the wire, a current-carrying angle setting means movably protruding into the arcuate groove, and the angle setting means, and one end of which is fixed to the basic shaft. An angle setting device for use in foundation construction, etc., comprising: a set angle display means, which is provided on the outside of the shaft and lights up when the angled set water line comes into contact with the angle setting means. It is in the composition of the vessel.

(Function) When the angle setting device of the present invention is used for setting the horizontal angle of the foundation shown in the embodiment, the angle setting means 16 is set in advance on the angle setting rotary plate 6 to obtain an angle of, for example, 90°. As shown in Figure 5 of the drawings, first fix the base 1 to the part where the angle is to be adjusted, and then
