JP3080998U - Light irradiation level - Google Patents

Abstract

(57) [Summary] [Purpose] It is possible to move and measure the level by one person, and because it is small and lightweight, it is rich in labor saving and can secure work safety. [Structure] A horizontal level with a level (1) on a level base (2), a light irradiator (4) incorporated in an adjusting cylinder (3), and a focus adjusting lens (5). It is characterized by.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a level with a light illuminator to move the level to a remote place.

[0002]

[Prior art]

 In the past, a level, level gauge, and level gauge were used to determine the level, and a water thread was stretched between two points to determine the level at the midpoint.

[0003]

[Problems to be solved by the invention]

 In order to determine the level at a place separated by a level, it is necessary to apply a straight patch called an idiot stick to make a fool farther than the level and to use it, and it is necessary to use two or more people. Each had to do the work of leveling, stupid sticks and markings. Also, since the level gauge is a peeping measurement using a telescope such as a level or transit, one person is always required to mark the level measuring point, which is the point to be measured, and fixed equipment such as a tripod is always required. Due to the large number of equipment, the equipment could not be temporarily fixed to a reference point such as a building. Also, the level gauge is heavy because it uses water, it takes time for the water surface in the hose to swing up and down and stabilizes, and the length of the hose increases in proportion to the distance, and it obstructs and works at heights. Is very difficult and dangerous. Also, when measuring the intermediate point with the water thread between the transferred levels, make sure that the longer the distance, the more the intermediate point becomes slack, and that the water thread is stretched around at 90 cm intervals at construction sites. When working on the inside, the water thread gets in the way when working inside and cannot move, and the level of the water thread moves or wraps around due to obstacles. There were many problems, such as worried about the yarn and the danger of falling. The present invention has been devised to solve these problems of the prior art.

[0004]

[Means for Solving the Problems]

 A level (1) is provided above the level stand (2). The light irradiation device (4) is combined with the focus adjustment lens (5), and the adjustment cylinder (3) is provided inside the level stand (2) provided in the adjustment cylinder (3). A light irradiation leveling device having the above configuration.

[0005]

[Action]

 Place or temporarily fix the light irradiation level at the reference point or reference plane. The level is checked with the level (1) at the top of the level table (2), and light is applied to the level measuring point where the level is to be obtained, and the focus is adjusted by the focus adjusting lens (5). Go to the level measurement point while irradiating light and mark. Since light takes the place of the water thread, the level can also be determined at the midpoint.

【Example】

 Hereinafter, embodiments of the present invention will be described. In FIG. 1 to FIG. 3, the level base (2) is a rectangular tube having a square cross section and a rectangular tube which is easy to be worked like aluminum and is light and hard to deform. At the top of the level table (2), seal the antifreeze in a slightly curved glass tube or plastic resin to leave a few air bubbles, and when the tube is horizontal, the air bubble is at the center. Attach (1). The light irradiator (4) uses an aluminum tube or a plastic resin or vinyl chloride tube, etc., and uses a battery as a power source and a miniature bulb or a light emitting diode for generating light inside the cylinder. Attach the focusing lens (5) to the front of 4). The adjusting cylinder (3) uses an aluminum tube, and the inclination of light irradiation is adjusted by an angle adjusting screw (8). The light irradiator (4) is fixed with six angle adjusting screws (8) in each of three places before and after, and the inclination is adjusted, and then it is mounted inside the level table (2). The present invention has the above-mentioned structure. When this is used, the bottom of the level table (2) is placed on the reference plane, and the level is adjusted so that the bubble comes to the center by the level (1) at the top. The light emitted from the light irradiator (4) is adjusted by a focus adjusting lens (5) so as to focus on the level measurement point. Since the light level is focused on the level measurement point and the light is illuminated, marking the light point with a pencil or the like completes the level movement. Also, the light can take the place of the water thread at the intermediate point, so that the level can be easily guided. By changing the direction of the level in this way, the level can be guided in the 360-degree direction. As shown in FIG. 2, a tripod can be used by using a fixing stand (6), or a tripod can be temporarily fixed to, for example, a pillar, a wall or a ceiling of a building. By tilting up and down around the axis of rotation, distortion, twist and tilt can be measured.

[0007]

[Effect of the invention]

 Since the present invention is configured as described above, it is easy to miniaturize without deteriorating its functions, and it is light and rich in workability. Measurement is easy and labor saving can be expected. In addition, since light is irradiated instead of the water thread, the work can be performed safely and accurately without the thread getting in the way.
