Description

Laser level with a plurality of laser measuring units

[0001] The present invention relates to a laser level for measuring horizontality and parallelism at construction sites or during interior construction, and more specifically, to a multi-functional laser level capable of simultaneously measuring distances to wall or ceiling structures and rapidly determining parallelism using multiple laser measuring instruments.

[0002]

[0003] In general, at construction or interior work sites, it is essential to accurately align horizontally and parallelly with reference lines when erecting walls or installing lighting fixtures on ceilings.

[0004] To address this, conventional methods involved repeatedly measuring and comparing distances at multiple points using measuring tapes, single-laser distance meters, or spirit levels. For example, when installing a square light fixture on a ceiling, the worker had to go through a complex and cumbersome process: temporarily fixing the fixture, measuring the distance from each of the surrounding walls to every corner of the light, and then adjusting the position and remeasuring if the alignment was off.

[0005] These conventional methods had problems such as long working times, a high possibility of errors occurring during the measurement process, and increased labor costs due to the need for two or more workers in some cases.

[0006]

[0007] The present invention was devised to solve the problems of the conventional technology described above, and aims to dramatically improve the accuracy and efficiency of the work by using a plurality of laser measuring modules to simultaneously measure the distance to a measurement target at multiple points and comparing the results to immediately determine whether it is parallel.

[0008]

[0009] A laser leveler equipped with a plurality of laser measuring devices according to the present invention for achieving the above-mentioned purpose may include a main body, a plurality of front laser measuring devices provided on the front of the main body, and a display unit provided on the upper part of the main body and displaying a measurement value measured by the laser measuring devices.

[0010] In addition, it may further include side laser measuring devices provided on both sides of the main body.

[0011] Furthermore, the display unit may display the distance measured by each laser measuring instrument, and the display unit may further include a notification device that indicates when the measurements of the plurality of front laser measuring instruments match.

[0012] In addition, the display unit may further include a notification device that indicates when the measurement value of the side laser measuring device matches.

[0013] Here, the front laser measuring device may be composed of two.

[0014] Furthermore, the above-mentioned display unit can light up when the measurements of two laser measuring devices match.

[0015] In addition, the above notification device can provide notification by illuminating a light or by sounding an alert.

[0016]

[0017] According to the present invention, parallelism can be quickly and accurately verified with a single measurement in various situations requiring parallel work, such as wall construction, lighting fixture installation, and the installation of picture frames or shelves. As a result, repetitive measurements and corrections become unnecessary, shortening work time and reducing worker fatigue, while enabling precise work with only one worker, thereby increasing labor efficiency.

However, the present invention is not limited to the presented embodiments and can be implemented in various forms.

[0026] and known features and techniques to clarify the description of the described embodiments of the present invention

[0027] A detailed explanation of may be omitted.

[0028] FIG. 1 shows an embodiment of a laser level equipped with a plurality of laser measuring devices according to the present invention.

[0029] Referring to the drawings, the laser level (100) of the present invention, equipped with a plurality of laser measuring devices, may include a main body, a plurality of front laser measuring devices (120) provided on the front of the main body, and a display unit (140) provided on the upper part of the main body and displaying a measurement value measured by the laser measuring devices.

[0030] In addition, it may further include side laser measuring devices (130) provided on both sides of the main body.

[0031] Furthermore, the display unit (140) may display the distance measured by each laser measuring device, and the display unit (140) may further include a notification device (not shown) that indicates when the measurements of the plurality of front laser measuring devices (120) match.

[0032] Additionally, the display unit (140) may further include a notification device (not shown) that indicates when the measurement of the side laser measuring device (130) matches.

[0033] FIG. 2 is another embodiment of a laser level equipped with a plurality of laser measuring devices according to the present invention. Referring to the drawings, the description is as follows.

[0034] Here, the front laser measuring device (220) may be composed of two.

[0035] Furthermore, the above-mentioned display unit (240) can be displayed in such a way that it lights up when the measurements of two laser measuring devices match.

[0036] In addition, the above notification device (not shown) can provide notification by turning on a light or by sounding a notification sound.

[0037] The present invention is not limited to the presented embodiments and can be implemented in various modified forms within the scope of the technical concept. Below, various modified embodiments based on the basic configuration of the present invention are described.

[0038] Additionally, the following various embodiments may be considered.

[0039] 1. Example of extended laser measurement function

[0040] The laser level of the present invention is based on having laser measuring devices on the front and both sides, but the number can be expanded to perform a wider variety of functions. For example, additional laser measuring devices can be installed on the upper and lower parts of the main body. In this case, the user can place the device against a wall and simultaneously measure the distance from the floor to the ceiling to find the vertical center point or easily verify the vertical parallelism of the object to be installed.

[0041] In addition, an embodiment in which laser measuring devices are installed in all four directions—front, back, left, and right—of the main body is also possible. This configuration is particularly useful when installing lighting fixtures or ceiling fans in the center of the ceiling. By positioning the device at any point on the ceiling and simultaneously measuring the distances to the four surrounding walls to find the point where the distances in all four directions coincide, the operator can quickly secure the accurate center point of the indoor space without separate calculations or repeated measurements.

[0042] 2. Examples of Advanced User Interface and Notification Methods

[0043] The present invention includes indicating whether the measured values ​​match by using an LED light or a numerical display. As another embodiment, the auditory notification function can be enhanced. For example, if the measurement distances on both sides match, a single "beep" notification sound is emitted, and if they do not match, an irregular "beep-beep-beep" sound is emitted to help the user concentrate on the task without looking at the device screen.

[0044] Furthermore, variable sound feedback can be provided where the interval of the notification sound shortens or the pitch rises as the difference in measurement values ​​decreases. This allows users to intuitively perceive that they are approaching a balanced state and make fine adjustments.

[0045] As a visual notification method, there is also a method of changing the color of the laser beam itself. A red laser beam is emitted when the measurement distance is misaligned, and a green laser beam is emitted when it reaches a perfectly aligned parallel state, allowing the operating status to be clearly recognized even from a distance.

[0046] 3. Example of Smart Function Interconnection

[0047] The laser level of the present invention may be equipped with a short-range wireless communication module, such as Bluetooth or Wi-Fi, internally. In this case, the device is linked with a dedicated application on a user's smartphone or tablet PC.

[0048]

[0049] Users can check distance values ​​measured by each laser meter in real time through the application, and save measured data and manage work history. For example, if the length of each wall in a specific space is measured and saved, the application can provide an additional feature that automatically calculates the area or volume of that space. Furthermore, collaboration efficiency can be enhanced by creating work plans based on the saved measurements or sharing data with colleagues.

[0050] 4. Examples of Modular Structure and Power Supply Method

[0051] As another embodiment of the present invention, the laser measuring part can be designed in a modular form. Users can additionally combine a side laser module or an upper / lower laser module with the basic main body as needed. This modular structure increases economic efficiency by allowing users to selectively configure only the necessary functions to suit their main type of work, without the need to purchase an expensive product that includes all functions.

[0052] Regarding the power supply method, in addition to the disposable battery method, an embodiment incorporating a rechargeable lithium-ion battery using a USB-C type port is possible. This allows users to conveniently charge anywhere using a smartphone charger or the like, thereby reducing the hassle of battery replacement and providing the effect of lowering maintenance costs.

[0053] 5. Example of an additional measurement mode

[0054] The laser level of the present invention can combine the functions of a digital level and an angle gauge by adding an accelerometer or a gyroscope sensor internally. Through this, the user can perform various measurement tasks with a single device by comprehensively measuring not only distances but also the inclination of floors or walls and the horizontal status of shelves.

[0055] Additionally, a 'reference value setting mode' can be added. If the user inputs a specific distance (e.g., 30 cm) as a reference value, this feature provides a notification when the measured distance matches that reference value when the device is moved. This can be very useful for repetitive tasks, such as hanging multiple picture frames at regular intervals from a wall or installing electrical outlets.
