Description

Adjustable vertical and vertical laser scales {vertical and horizontal alignment apparatus capable of moving up and down}

The present invention relates to a horizontal vertical laser scale device used in a construction site, and more particularly to a horizontal vertical laser scale device that can be set at the same time the horizontal reference line and the vertical reference line, the structure is improved so as to be elevated by the drive unit.

In general, there is a necessity to accurately set the vertical reference line and the horizontal reference line, such as building blocks perpendicular to the ground or laying the wood horizontally.

In this case, until now, the horizontal and vertical reference lines have been mostly set in a very primitive way. An example of such a conventional method is illustrated in FIG. 1.

FIG. 1 illustrates a method of setting a horizontal reference line between two points to measure whether two points A and B are exactly horizontal to each other. According to this method, the operator installs a transparent tube 10 having a hollow portion formed between two points A and B to be measured, injects a liquid 11 such as water therein, and then, It was determined whether or not the horizontal alignment between the two points A, B according to whether or not the water surface matches the preset baseline.

Referring to FIG. 2, which shows another conventional horizontal reference line setting method, a horizontal scale 20 containing antifreeze 21 is installed in a transparent container between two points A and B to be measured, and the surface of the antifreeze 21 is provided. The horizontal alignment is determined according to whether or not it is horizontal with the preset reference line.

3 shows a conventional vertical scale for setting a vertical reference line, and is vertically installed between two points C and D to be measured. That is, first, the hanging hook 30 is suspended at a point C of the ceiling 100 by using the string 31, and then hangs it up to the bottom 200, which is the point at which the hook 30 is in contact with the floor 200. Mark D to set the vertical reference line.

However, such horizontal scale instruments are not only cumbersome, but also unreliable in measuring the degree of agreement between the surface and the baseline after visually installing the instrument between two points to be measured.

In addition, since the vertical scale 30 should be stretched by using the line 31 as much as the length between the two points C and D to be measured, the vertical reference line should be set. The measurement task was difficult.

First of all, despite the necessity of setting the horizontal line and the vertical line at the same time in the actual construction site, the apparatus has been inconvenient to set the horizontal reference line and the vertical reference line separately.

In addition, there are conventional devices for setting horizontal and vertical reference lines in addition to such kinds of means, but these are very expensive and the operation also has complex disadvantages.

The present invention was devised to solve the above problems, and there is no need to install the device by moving according to the point to be measured at the construction site, and it is very easy and convenient to measure the horizontal reference line and the vertical reference line at the same time. It is an object of the present invention to provide a movable vertical and horizontal laser scale.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 shows the configuration of the liftable horizontal vertical laser scale according to a preferred embodiment of the present invention. Referring to the drawings, the vertical and horizontal laser laser device of the present invention is composed of a scale 40 and a drive unit 70 for lifting the scale 40.

The scale 40 forms a reverse cone shape, and is divided into an upper end 41 and a lower end 42 as shown in FIG. 5. These upper and lower ends 41 and 42 may be coupled to each other by, for example, a screw. The upper surface of the upper end portion 41 is provided with a coupling portion 45 is formed with a coupling hole 45a so that the string 60 can be coupled.

There are horizontal holes 42a and 42b formed horizontally on the side of the lower end 42, and vertical holes 42c are formed downward to be perpendicular thereto. At least one of the horizontal holes 42a and 42b may be formed, and two or more horizontal holes 42a and 42b may be formed as necessary.

The upper and lower ends 41 and 42 have hollow portions, and the laser oscillation device 50 is inserted into the hollow portions. The laser oscillator 50 is aligned with the horizontal holes 42a and 42b and horizontal laser oscillators 51a and 51b which emit the laser beam laterally through these horizontal holes 42a and 42b, and vertically. And a vertical laser oscillation portion 52 which is aligned with the hole 42c and emits the laser beam downwardly through the vertical hole 42c.

Preferably, these laser oscillators 51a, 51b, 52 include a semiconductor laser including a surface light laser that emits a laser beam in the stacking direction of the semiconductor material layer. In addition, the laser oscillation device 50 is provided with a battery 53 as a power source.

Referring back to FIG. 4, the driving unit 70 lifts the scale 40, and brackets 72a and 72b are formed on both upper surfaces of the housing 71, which is a body, and the brackets 72a and 72b. ), A screw hole 73 is formed.

The housing 71 is provided with attachment means for attaching the driving unit 70 to the ceiling. More specifically, a plurality of magnets 74 are attached to the upper surface of the housing 71. In addition, the front of the housing 71 is provided with a display window 75 such as a fluorescent display tube or an LCD display. This display window 75 is used to display the length of the string 60 connected to the scale 40.

Reference numeral 76 denotes a power switch for turning the driving unit 70 on and off, and reference numerals 77a and 77b denote lifting and lowering buttons for lifting and lowering the scale 40, respectively.

Referring to FIG. 6, in which the internal configuration of the driving unit 70 is shown, a driving motor 80 electrically connected to the lifting and lowering buttons 77a and 77b is installed in the housing 71. The pulley 81 is coupled to the rotation shaft of the motor 80. The pulley 81 is wound with a cord 81 connected to the coupling part 45 of the scale 40 so that the scale 40 is raised or lowered according to the rotation of the driving motor 80. Optionally, the drive motor 80 is preferably a step motor.

The operation of the liftable horizontal and vertical laser scale device according to the present invention having the configuration as described above will be described.

First, as shown in FIG. 6, at a construction site where a liftable horizontal and vertical laser scale device of the present invention is installed, the driving unit 70 is installed at a point C of the ceiling 100. In general, since the bar 101 made of steel is installed in the ceiling structure, the driving unit 70 may be maintained on the ceiling by attaching the magnet 74 to the bar 101. In this state, the drive unit 70 may be firmly fixed to the ceiling by selectively coupling the fixing screw 85 to the screw hole 73 formed in the bracket 73 on the upper surface of the housing 71. This fixing means is not limited by this embodiment and any means capable of fixing the drive unit 70 to the ceiling should be understood to be included in the present invention.

In this state, when the power switch 76 is turned on and the down button 77b is pressed, the drive motor 80 is rotated to release the string 60 wound on the pulley 81, thereby lowering the scale 40. do. In this case, the length of the loosened line 60 is displayed on the display window 75. Here, the configuration of the pulley and the drive motor can be any number of modifications at the level of those skilled in the art, it is also possible to intervene a relay gear to rotate the pulley when the drive motor rotates.

Once the scale 40 is lowered to a point to be measured, for example, between two points A and B in FIG. 6, the laser oscillator 50 is driven to drive the laser beam from the laser oscillator 51a, 51b, 52. Eject

At this time, the laser beam emitted from the laser oscillator (51a) (51b) is emitted through the horizontal holes (42a) (42b) to enter the point A. In this state, when the scale 40 is slowly rotated by a predetermined angle, the laser beam draws a horizontal trajectory along the direction of the arrow. Therefore, if the laser beam that draws the horizontal trajectory is accurately incident on the point B, the two points A and B are in the exact horizontal alignment, and the horizontal trajectory of the laser beam coincides with the horizontal reference line. When the horizontal alignment between the two points is made, a horizontal reference line is drawn using a black line.

According to the scheme of the present invention, even if the distance between two points to draw the horizontal reference line is arbitrarily set, it is possible to set the horizontal reference line for all directions by simply rotating the horizontal vertical laser scale.

On the other hand, if you want to set the horizontal reference line between the two points A ', B' at different heights by appropriately operating the lifting and lowering buttons 77a and 77b again to lower the scale 40 to the corresponding position. You can set the horizontal baseline in the same way.

Preferably, a remote controller, that is, a remote controller can be used so that a user working on the floor can easily operate after installing the scale device of the present invention, and the remote controller window 78 to which the beam emitted from the remote controller is incident is provided. The driving unit 70 may be provided.

On the other hand, when setting the vertical reference line between the two points C, D, since the laser beam emitted from the laser oscillator (52 in Fig. 5) is incident perpendicularly to the floor 200 through the vertical hole 42c, it is estimated as conventionally. You can easily find point D without having to lower the weight all the way to the floor.

Embodiments exemplified as described above are merely one embodiment of the present invention and can be modified and practiced at any level of ordinary skill in the art. That is, in the present embodiment, the body of the scale 40 is described as a conical shape of reverse, but need not be limited to this shape. In addition, the body has been described as being configured to be separated into the upper end and the lower end, but is not limited to this, for example, the body may be composed of a single body formed with a hollow portion and the laser oscillation device may be inserted into the hollow portion.

The vertically and horizontally adjustable laser laser scale according to the present invention can not only set the horizontal reference line and the vertical reference line at the same time, but also its configuration is simple and its manufacturing cost is also low. First of all, it is possible to easily set all horizontal reference lines regardless of the direction or height by installing only one point of the ceiling at the work site and simply operating the switch of the drive unit or the remote controller.
