DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blackout laser device for projecting a laser beam onto an object to be irradiated, such as a wall, a ceiling, or a floor, when performing blackout work at a building site or the like. More specifically, the present invention relates to a blackout laser device in which an oscillator having a laser light emitting device is swingably supported on an apparatus body.

[0002]

2. Description of the Related Art Conventionally, this type of ink-marking laser device has
It is based on a configuration in which a rocking body to which a laser light emitting device is attached is pivotally supported by a vertical adjuster so as to be swingable in the vertical direction. Since the rocking body is always supported in a swingable state, the rocking body swings unnecessarily during transportation or work, causing a problem that the laser light emitting device or the device itself is damaged.

Therefore, as a blackout laser device having a device for fixing the oscillating body at the time of movement for transportation or operation, a laser device disclosed in Japanese Patent Application Laid-Open No. 8-271252 is known.

It can swing freely with respect to.

Since the microswitch 33 is connected to a circuit connecting the laser light oscillation circuit 15a and the battery 17, the ON / OFF of the microswitch 33 causes a current to flow to the laser light oscillation circuit 15a. Can be opened and closed, and the operation and non-operation of the laser oscillation module 15 can be performed.

A mode of use in the laser device for blackout having the above configuration will be described. As shown in FIG.
When the black-out laser device is used, since there is no interference on the outer peripheral surface of the rocking body 6 positioned at the center, the rocking member 6 can be rocked freely. 26 is located at the large diameter portion 29a of the cam portion 29.

When the rocking body 6 is swingable, the locking member 22 of the rocking body fixing device 20 is rotated in a direction away from the rocking body 6, and the pressing portion of the locking member 22 is pressed. twenty five
Are in contact with the inner peripheral surface of the base 21.

The pressing portions 2 of the three locking members 22,.
Since one of the pressing portions 25 of 5,... Presses the switch lever 34 of the micro switch 33 embedded in the base 21, the micro switch 33 is turned on, and laser light is emitted from the laser oscillation module 15. The light is projected, and it is possible to perform a blackout operation.

Next, a case in which the use of the blackout laser device is terminated will be described with reference to FIG. The rocking body
6 to fix the operation piece 31 protruding from the operation member 28.
Thus, the operation member 28 is rotated. That is, by moving the operation piece 31 counterclockwise, the rotation groove 32 formed in the operation member 28 slides on the support column 4 and the operation member 28 is rotated about the center of the swing body 6 as the rotation center. Rotates.

When the operation member 28 is rotated, the cam portion 29 provided on the operation member 28 is also rotated, so that the projection 26 provided on the locking member 22 follows the movement of the cam portion 29. While sliding. At this time, the projecting portion 26 is
It is located at the small diameter portion 29b of 29.

The protrusion 26 follows the movement of the cam 29 and moves to the small-diameter portion 29b.
The locking member 22 provided with is also rotated about the support column 4 as a rotation center, and the locking member 22 abuts on the rocking body 6, that is, the locking portion 24 formed on the locking member 22 is rotated. It comes into contact with the outer peripheral surface of the oscillator 6.

Since the locking members 22 are evenly arranged at three equal positions on the base 21, the locking members 22
22 comes into contact with the triangular position of the outer peripheral surface of the oscillating body 6 evenly, so that the locking member 22 surrounds the oscillating body 6 so that the oscillating body 6 can be securely fixed.

In addition, the three locking members 22 are
By rotating the operating member 28, all the locking members 22 move while rotating in the direction of the oscillating body 6 in synchronization with each other.
4,... Come into contact with each other so as to surround the outer peripheral surface of the oscillator 6, thereby fixing the oscillator 6.

Further, when the locking member 22 rotates, the pressing portion 25 of the locking member 22 separates from the switch lever 34, the micro switch 33 is turned off, and the laser beam is emitted from the laser oscillation module 15. The light emission stops, and the blackout operation ends.

Since the cam portion 29 is provided with a step portion 30 for locking the projecting portion 26, the projecting portion 26
In order to pass through the step 30, artificial force is required, so that the operation member 28 does not inadvertently reversely rotate and the fixed state is not released.

That is, even if the operating member 28 naturally rotates clockwise and the projecting portion 26 located at the small diameter portion 29b of the cam portion 29 slides to the step portion 30, the cam portion of the step portion 30 29 is bent to the inner diameter side, and the protrusion of the step portion 30 protrudes.
26 is locked, so that the projection 26 cannot naturally pass through the step 30.

Therefore, the rocking body 6 can be freely fixed by the rocking body fixing device 20, and the power of the device itself can be turned on and off.

The present invention is not limited to the above-described embodiment, and the design can be changed as appropriate. For example, at least two cylinders are provided, and the cylinders are locked by synchronizing the cylinders. It may be a member that comes into contact with the outer peripheral surface of the oscillator 6 to fix the oscillator 6. In short, if the plurality of locking members are operated and moved synchronously by the operating member, and the locking members can be moved by the operating member to come into contact with and separate from the oscillating body, the intention of the present invention is as follows. Is about to do.

The shapes of the locking member 22, the cam portion 29 and the like are not limited. In short, by operating the operation member,
All the locking members 22 can be operated simultaneously, and
The present invention is intended if the structure is such that the abutment 22 comes into contact with the outer peripheral surface of the rocking body 6.

Further, in the present embodiment, the cam portion 29 is provided on the operating member 28 and the protruding portion 26 as a cam follower is provided on the locking member 22, but the reverse is also possible. That is, the cam portion 29 may be provided on the locking member 22, and the protrusion 26 as a cam follower may be provided on the operation member.

The locking member 22 and the cam portion 29 are provided in three pairs, but if there are two or more pairs, they come into contact with each other so as to surround the outer peripheral surface 6 of the oscillating body 6 and fix the oscillating body 6. be able to. However, in order to securely fix the oscillator 6, it is preferable that the number of pairs is three or more.

Further, in the present embodiment, the support column 4 is used as the pivot of the locking member 22, but the present invention is not limited to this, and a new pivot may be provided. .

In this embodiment, a switch composed of a micro switch is used as the operating circuit switch. However, as long as the circuit can be turned on and off, a limit switch, a magnet switch, or the like may be used. Good.

Further, in the present embodiment, the microswitch is embedded in a groove formed on the lower surface of the base 21, but may be simply fixed directly on the lower surface of the base 21.
