Abstract
Description
Background The present invention relates generally to laser leveling devices and, more specifically, to an electronic accessory designed to' assess and confirm the perpendicular projection of laser beams from existing laser levels. Laser levels are essential tools widely used in the construction, surveying, and many other industries, where precision alignment and leveling tasks are vital. These instruments project a laser beam, allowing professionals to establish straight, level, or plumb lines in various applications. Ensuring that the laser is projected perpendicularly to a reference surface, typically a wall or floor, is fundamental to guarantee the accuracy and reliability of the measurement. However, the calibration of these laser levels to ensure that they are projecting beams perpendicularly has been a challenge. It is crucial that these devices project their beams accurately to prevent measurement errors, which can have significant implications in construction or surveying projects. For professionals using these tools, ease of calibration and confirmation that the device is accurately set up can save time and reduce potential errors.

Accordingly, this description of the present technology is set forth without any loss of generality to, and without imposing limitations upon, the present technology. The innovative nature of this invention lies in its capability to enhance the functionality of traditional laser levels by ensuring that their projections are perfectly perpendicular to a given surface. This is crucial for a variety of applications, including construction, interior design, and other fields where precision alignment is necessary. The following detailed description outlines the components of the invention and their synergistic operation, as visualized in Figure 1, Referring to Figure 1, the proposed invention consists of the following parts: Screw Thread (1): Situated at the topmost portion of the device, the screw thread is specifically designed to seamlessly interface with existing laser levels. Its universal design ensures compatibility with a wide range of laser level models, offering users the flexibility to utilize the device without needing specialized equipment. Adjustment Screw Thread (2): This component is a finer, more intricate version of the primary screw thread. It permits the user to make micro-adjustments to the positioning of the laser level, ensuring that the device can be calibrated with the utmost precision, accounting for even minute discrepancies in alignment. Adjustment Thumb Wheel (3): Adjacent to the adjustment screw thread, the thumb wheel offers tactile control to users. It is ergonomically designed to provide smooth and efficient manual adjustments. Through its rotation, users can fine-tune the alignment of the attached laser level with ease. AA Battery Compartment (4): The heart of the device's power system, this compartment has been engineered to house standard AA batteries securely. It ensures that the device remains operational for extended periods, catering to prolonged usage without the constant need for battery replacements. Laser Distance Sensor (5): Arguably the most critical components, the two laser distance sensors are set at a predefined angle relative to one another. They measure the distance from the wall to the laser beam projected by the attached laser level Their precise positioning and high sensitivity ensure accurate readings, which are then used for calibration. LED Display (6): The LED display serves a dual purpose: it offers a visual representation of the sensor readings and provides immediate feedback on the calibration status. Once the device confirms that the attached laser level is projecting its beam perpendicularly, the LEDs illuminate, signaling successful calibration to the user. Laser Distance Sensor Projected Beam (7): This beam, emitted by the distance sensor, travels to the reference surface and returns, allowing the sensor to calculate the distance. Its sharpness and precision play a pivotal role in the accuracy of the calibration process. Wall / Surface (8): This is the reference against which the entire calibration process is benchmarked. It can be any flat surface, such as a wall, floor, or ceiling, that the laser level's projection is intended to be perpendicular to. Operational Synergy: Upon securing an existing laser level to the invention using the screw thread (1), the device is activated. Power is drawn from the housed AA batteries in the battery' compartment (4), which ensures the invention’s prolonged operation. The user can then fine-tune the position of the attached laser level using the adjustment screw thread (2). This fine adjustment capability is particularly useful when dealing with surfaces that may not be perfectly even or when meticulous precision is required. The adjustment thumb wheel (3) further aids this process, allowing for user-friendly, tactile control, making micro-adjustments both smooth and intuitive. With the laser level in place and operational, it projects its beam towards the reference wall / surface (8). In tandem, the two laser distance sensors (5) emit their respective laser distance sensor projected beams (7) towards the same wall or surface. These sensors, strategically positioned at a predefined angle to one another, measure the distance between their emitted beams and the wall. Given the fixed angle between the sensors and utilizing the principle of the Pythagorean theorem, the device's built-in computational mechanism calculates the discrepancies, if any, between the laser level's projection and a perfect perpendicular. The LED display (6) serves as an immediate feedback system throughout this process. If the attached laser level's beam is confirmed to be perfectly perpendicular to the wall / surface (8), the LED display illuminates, signaling to the user a successful calibration. Conversely, if adjustments are still required, the LED indicators can guide the user on the necessary corrections. In summary, this invention exemplifies a holistic approach to laser level calibration. By synergistically combining each component— from the screw threads for attachment, the battery compartment for power, to the laser sensors for distance measurement, and the LED display for real-time feedback — it offers users an unparalleled tool. This invention not only ensures that laser level projections are accurate but also simplifies the calibration process, making it both efficient and user-centric. Although the present disclosure has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the inventive aspects of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
