[Problems to be solved by background art and device]

 In construction sites such as civil engineering and construction, vertical and horizontal markings are performed as needed, but for efficient construction, these markings must be performed in a short time. On the other hand, various types of conventional inking devices using lasers are already known, but all have complicated structures and require a considerable amount of time to get used to handling. In addition, equipment may be too large to carry in, especially in small sites. Furthermore, when installing the equipment, it is necessary that the floor is firm. For example, in the case of an unstable object such as a scaffold, there is a possibility that the ink cannot be accurately extracted.

[0003] The present invention focuses on these points, and an object of the present invention is to provide a laser device that can easily perform inking in a short time even in a narrow place or an unstable place. It is assumed that.

Alternatively, a switch of the laser beam means is provided at a fulcrum portion of the structure, and a laser beam is output when the structure is supported at the fulcrum.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 shows the overall configuration of the first embodiment of the present invention. In FIG. 1, the plunger 10 includes an upper cylindrical portion 11 and a lower conical portion 12. Four laser pointers (laser oscillators) 21 to 24 are mounted on the upper end surface of the column 11 so as to be substantially orthogonal to each other on a horizontal plane. On the other hand, a laser pointer 25 is attached to the tip of the conical portion 12.

[0007] The laser pointers 21 to 24 of the cylindrical portion 11 are configured to output laser beams in the horizontal direction indicated by arrows FA1 to FA4, and the laser pointer 25 of the conical portion 12 is indicated by an arrow FB. The laser beam is output in the vertical direction shown. At the center of the laser pointers 21 to 24, a threader 31 for tying a thread (or wire) 30 for suspending the plunger 10 is provided.

The laser pointers 21 to 25 have a configuration in which a semiconductor laser element using, for example, a button battery as a power supply is built in. Since the semiconductor laser element can output laser beams in two directions, at least two laser elements are required. The switches S for turning on and off the laser pointers 21 to 25 may be provided as appropriate. For example, if the laser pointers are turned on when the thread pusher 31 is pulled, the laser in the use state may be used. It is convenient that a beam is output.

Next, a use state of the above-described embodiment will be described with reference to FIG. This example is an example of a case where horizontal blackout is performed on the wall surface 42 so as to be at a predetermined height from the reference point 41 of the floor surface 40. The swing 10 is suspended from the ceiling using a thread or the like. Then, the switch S is turned ON, and a laser beam is output from the laser pointer 25 in the direction indicated by the arrow FB. The suspension position of the swing down 10 is adjusted so that the laser beam hits the reference point 41. Next, the height of the laser beam in the horizontal direction from the reference point 41 is adjusted to a predetermined value. Then, the positions where the laser beams hit the laser pointers 21 to 24 are at predetermined height positions from the reference point 41.

On the other hand, in the present embodiment, four laser pointers are provided as described above. For this reason, if any two beams, for example, the beams of the laser pointers 21 and 22 are made to hit the wall surface 42, it is possible to easily perform horizontal blackout by connecting them. Even if the floor surface 40, wall surface 42, or ceiling is inclined or curved, the ink can be satisfactorily marked because the laser beam is used. In addition, since it is sufficient to install the plunger 10, it is possible to carry out blackout work even in a small site. Note that the above method of use is merely an example, and various methods of use are possible as needed.

Next, FIG. 3 shows a second embodiment of the present invention. In the figure, the inking device is mainly composed of a structure for balancing, and balancers 53, 54 for adjustment are screw-mounted on legs 51, 52 having both ends of an arm 50 extending in the orthogonal direction. It has been. A fulcrum 55 is provided below the center of the arm 50, and laser pointers 60 and 61 are provided above the arm 50 along the longitudinal direction of the arm 50. Laser beams are output from the laser pointers 60 and 61 in directions of arrows FC1 and FC2, which are substantially opposite directions. As described above, since the semiconductor laser element can output a laser beam in two directions, the laser pointers 60 and 61 may be constituted by one laser element. The above components are symmetrical with respect to the fulcrum 55, and have a configuration like a so-called "Yajirobe".

It is convenient that the switches of the laser pointers 60 and 61 are turned on when the fulcrum 55 is pressed, for example, when the apparatus is installed as shown in FIG. Further, the balancers 53 and 54 for adjustment may be provided only on one of the feet 51 and 52. Only one laser pointer may be provided.

Next, a description will be given of a use state of the second embodiment configured as described above. First, the fulcrum 55 of the ink marking device is applied to the top surface of an appropriate convex support 70, and the entire device is supported 70. To support. Note that a jig in which the support 70 is erected on a plate or the like may be separately prepared. Next, if necessary, the balancers 53 and 54 are adjusted so that the arm 50 is balanced around the fulcrum 55. Then, the laser beams of the laser pointers 60 and 61 are output in the horizontal direction.

Here, when the arm 50 is slightly rotated about the fulcrum 55 in the direction of the arrow FD, the laser beam spot on the wall moves in the horizontal direction. This makes it possible to easily perform blackout in the horizontal direction. Even if the optical axis of the laser beam output from the laser pointers 60 and 61 is tilted from the horizontal direction, if the arm 50 is rotated while maintaining the tilted state, the horizontal direction of the laser beam is similarly determined from the beam trajectory. Can be issued. Also in this embodiment, similar to the above-described embodiment, it is possible to perform blackout in a horizontal direction in a narrow site. The device is small and portable.

FIG. 4 shows another example of the second embodiment. In this example, the arms 81 to 84 of the blackout device extend in four directions substantially orthogonal to each other, and relatively long legs 85 to 88 extend in the orthogonal directions at the ends of each arm. A fulcrum 90 is provided at the intersection of the arms 81 to 84. The laser pointer is housed in the arms 81 to 84, and the legs 85 to 88 are provided with balancers 91 to 94, respectively. Note that the balancers 91 to 94 are screw-type movable in the direction of arrow FE. Also in this example, the basic operation is the same as the example of FIG. Since the laser beam is output in four directions as in the example of FIG. 1, it is possible to easily perform horizontal marking from two beams formed on the wall surface.

There are many embodiments of the present invention, and various modifications can be made based on the above disclosure. For example, various laser pointers have already been put into practical use, and any of them may be used. In the above embodiment, a plurality of pointers are used. However, a plurality of laser beams may be obtained by optically dividing laser light output from one laser oscillator. The plumb bob and the shape of the structure may be changed as necessary. For example, in the above embodiment, the structure for balancing is branched in two directions or four directions. However, if the balance can be obtained, the structure may be appropriately changed in three directions or the like as needed. Further, even in the four directions as shown in FIG. 4, the angles do not necessarily have to be orthogonal. The shape of the structure does not need to have arms and legs, and may be, for example, an arcuate shape (so-called jarrobe shape) that draws an arc as a whole. Of course, the longer and larger the structure is, the more convenient it is for balancing, and it has the advantage of requiring little adjustment by a balancer. In the above example, the longer the foot, the better.
