Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention avoids obstacles in the middle of a laser beam when the level of a wall or the like is raised by a level laser irradiating device, for example, in the construction work or finishing work of a building. The present invention relates to a laser light reflecting device which is a jig for outputting a laser level.

[0002]

2. Description of the Related Art Conventionally, in leveling with a laser beam, for example, a level laser irradiating device is set at a certain position on the floor surface, while irradiating the laser beam.
This is rotated to irradiate a laser beam, and a laser beam or a light receiver projected on an object picks up a point and marks out a level.

[0003]

However, as shown in FIG. 8, an obstacle 2 such as a pillar (H-shaped steel) or a wall is provided between the level laser irradiation device 20 and the laser receiving surface.
If there is 1, the extension line cannot receive the laser beam, and the level cannot be set. Thereby,
The level laser irradiating device 20 will be set again at another place, or the level will be set by rough estimation. Also, when there are many partitions in a small room such as a toilet, there is a case where there is no space for setting the level laser irradiation device even when trying to create a tiled level. As described above, there is a problem that leveling by the level laser irradiation device is a laborious work.
The laser light reflecting device according to the present invention has been proposed to solve such a problem.

[0004]

The gist of the laser light reflecting device according to the present invention to solve the above problems is to provide a mirror, a rotary shaft for suspending the mirror, and a rotary shaft for rotatably mounting the rotary shaft. And a windshield cover that covers the mirror and is attached to the main body.

A weight is attached to the lower portion of the mirror to make the mirror surface substantially parallel to the vertical direction; and a base is provided to attach the laser light reflecting device to the installation location. An arm portion having a root portion swingably supported is projectingly provided on the base, and a main body is supported on a tip end portion of the arm; and, further, an installation place is provided on the base. It includes the provision of any one or all of a magnet plate, a suction cup receiving port, and a board insertion jig for temporarily fixing to.

According to the laser beam reflecting device of the present invention, when the laser beam emitted from the level laser beam irradiating device cannot directly mark the leveling portion such as a wall, the laser beam is appropriately separated. It becomes possible to mark out with laser light by reflecting from the place. This laser light reflecting device can be easily attached to a pillar, a wall or the like to set a reflecting mirror. Therefore, in the conventional example, it takes time to move the level laser irradiating device to a position where marking can be performed, but the laser light reflecting device according to the present invention eliminates the time and labor required for work.

Under the mirror, a mirror surface is automatically maintained in a vertical state by a weight for making the mirror surface substantially parallel to the vertical direction.

Further, a base is provided for attaching the laser light reflecting device to an installation location, and an arm having a root portion swingably supported is projectingly provided on the base, and a tip of the arm is provided. By allowing the main body to be supported by the portion, it becomes possible to guide the laser light to a narrower area and irradiate it.

Further, the base is provided with any one or all of a magnet plate, a suction cup receiving port, and a board insertion jig for temporarily fixing it to an installation place, so that any position can be obtained. Can be easily set.

It has a main body 4 and a windshield cover 5 which covers the mirror 2 and is attached to the main body 4.

A weight 2a is attached to the lower portion of the mirror 2 to make the semicircular mirror surface substantially parallel to the vertical direction. Further, as shown in FIGS. 2 to 3, the main body 4 is provided with a magnet plate 6 and a suction cup receiving port 7 as a temporary fixing member for temporarily fixing the main body 4 to an installation place suitable for reflecting laser light. Alternatively, all of the board insertion jigs 8 are provided. In some cases, any one of these temporary fixing members may be provided.

The mirror 2 is suspended by a rotating shaft 3, and a weight 2a keeps the mirror surface substantially parallel to the vertical direction. The windshield cover 5 is a transparent body, a semitransparent body, or a colored transparent body that entirely covers the mirror 2, and eliminates the adverse effect of the mirror 2 being shaken by wind or the like. By the temporary fixing member,
The laser light reflection device 1 can be easily magnetically attached or attached to any position such as the surface or wall surface of the H-shaped steel for temporary fixing.

As a further improved embodiment of the laser light reflecting device 1, as shown in FIGS. 4 to 6, a laser light reflecting device 9 is provided for attaching the laser light reflecting device 9 to a desired installation place, for example, A rectangular flat plate base 10 is provided, and an arm 11 having a root 11a swingably supported is projectingly provided on the base 10, and the main body 4 is supported at the tip of the arm 11. Is configured.

The laser reflecting mirror 12 is a flat mirror. In this mirror 12, the rotary shaft 3 is fixed to the upper part thereof, and the weight 12 is fixed to the lower part thereof.
a is provided. The rotary shaft 3 is rotatably supported around its axis by a main body 4 or a windshield cover 5.

The shaft portion 1 is attached to the base portion 11a of the arm portion 11.
1b and 11c are provided and are rotatably supported by a bearing support member 10a on the base 10 side. For example, when the base 10 is temporarily fixed to a vertical plane such as a wall by the arm 11 as shown in FIG. 4, the rotatable arm 11 is horizontally swung at an arbitrary angle. By that, the mirror 12
The reflecting surface of can be rotated and moved in the horizontal direction.

The presence of the arm portion allows the mirror 12 to be formed into a flat plate shape, and it is not necessary to form the mirror 12 into a semi-cylindrical shape as in the case of the laser light reflecting device 1, thus reducing the cost. It will be easier to obtain.

By using the laser light reflecting device 1 or the laser light reflecting device 9, as shown in FIG. 7, even if there is an obstacle 21 such as an H-shaped steel, the magnet plate 6, the suction cup receiving port 7 or the board difference. The laser light reflecting device can be temporarily fixed to the obstacle 21 by a temporary fixing member such as the insertion jig 8. Then, the laser light from the level laser irradiation device 20 is irradiated onto the mirror surfaces of the temporarily fixed laser light reflecting devices 1 and 9.

By rotating the level laser irradiation device 20 or rotating the mirror 12 with the arm portion 11,
In a wide range or on a wall surface in a narrow place,
It becomes possible to receive a laser beam.
