Mano-D5-Handheld laser rangefinder with 5 laser units and digital inclinometer

专利摘要:
Handheld laser rangefinder with 5 laser units and digital inclinometer (Fig. B1), for use mainly in the construction industry. In the rangefinder, a laser unit is located at each end of the box (1,2) so that they measure in opposite directions in the same axis to the left (1) and right (2), respectively. Next to each of these is located a laser unit (3,4) measuring perpendicular to this axis downwards, these two being parallel. In the center of the box is a laser unit (5) which also measures perpendicular to the axis, but upwards. The laser rangefinder can thus measure in opposite, perpendicular and parallel directions to each other at the same time, ie. 0⁰ (1), 90⁰ (5) 180⁰ (2), 270⁰ (3), 270⁰ (4). This provides flexible positioning and orientation. You can make point measurements and markings with just one measurement, and make sure the measurements are parallel and perpendicular. The invention achieves efficient and accurate measurement and marking.

专利说明:

The invention relates to a laser rangefinder with 5 laser units built into an oblong box which is essentially handheld. A laser unit is located at each end of the box so that they measure in opposite directions in the same axis to the left and right, respectively. Adjacent to each of these is a laser unit measuring perpendicular to this axis downwardly, these two being parallel and substantially spaced apart. In the center of the box is a laser unit that also measures perpendicular to the axis, but upwards. The laser rangefinder can thus measure in opposite, perpendicular and parallel directions to each other at the same time, ie. 0 °, 90 ° 180 °, 270 °, 270 °. When the lasers are activated, they measure continuously. The measuring instrument also has a digital inclinometer built into it, which also functions as a digital spirit level.
With the handheld laser rangefinders already known, it is often seen that an inclinometer is also built-in. However, in the known handheld models, only 1 laser unit is used for measurements in one direction.
Several simple measurements as well as markings (marking of targets) can be effectively handled by these handheld laser rangefinders. However, these have certain limitations that make it tedious and time consuming and sometimes require the involvement of other aids to make measurements and markings mainly within the construction industry.
The first disadvantage lies in having to place the odometer at one end point. This is especially a disadvantage of working at height from scaffolding and ladders. It is often necessary to move ladders or scaffolding to obtain a measurement. This is time-consuming, destructive to the work rhythm and can cause more work injuries, as the craftsman will sometimes stretch into dangerous postures to avoid moving. When working from the floor, there can also be a slight loss in efficiency, by constantly having to position itself at the end point and possibly. bad postures. Some rangefinders have partially solved the problem of the possibility of mounting on a tripod (auxiliary). You can then shoot to several points and the distance meter can calculate a length based on geometric calculation. Measurements from a tripod can of course have an advantage mainly for, for example, architects who can take many measurements from the same position to their drawings. For the performing craftsman, however, this is a difficult task, as he almost always uses targets for a specific task he performs, ie he stands right where the work is done, and has to use goals and markings right there (hence the definition of the future craftsman). Therefore, it is extra time-consuming to reposition and find a tripod. In any case, the laser rangefinder is mounted on a tripod thus no longer handheld.
The other disadvantage is that the marking of items that are common to the craftsman requires several processes. A point almost always has two references, for example, down and
DK 2017 00500 A1 to the side. To mark such a point, one will usually take a measurement to the side and make a dash. Then you will find the target down by that line and set that target with a line. These two strokes will rarely intersect in the first attempt, which is why you now have to make the goal again and set aside a new line that now intersects. One must therefore make 3 measurements to deduce one point. In addition, in some cases, for example, freshly painted walls remove the first line again if it remains visible, depending on the task. Incidentally, this method is the same whether using a laser rangefinder, thumbnail or tape measure. It has to be said that it is a disadvantage that one can only measure in one direction at a time when you consider how often a process has to be to allocate points.
The third major disadvantage of being able to measure only in one direction at a time with a handheld laser rangefinder is that you do not have secure control of whether the measurement is parallel or perpendicular to the desired. It is necessary to do this on purpose, or to carry out control measurements if necessary. When taking measurements, for example, around the center of a ceiling surface, it becomes difficult to reach targets, as you are now away from lines you could escape, and you therefore shoot the target freehand. The risk of inaccurate measurements is increased the further away from other escape lines. Therefore, making parallel or perpendicular measurements in these situations is not accurate with a single laser unit laser rangefinder.
This problem is clarified when one has to find the center point of a ceiling surface, which is relatively often needed, for example by centering ceiling panels, lamp outlets, many other divisions based on the center point. In order to find the center point, the two first mentioned disadvantages will also apply (moving ladders around to endpoints and the lines do not intersect in the first attempt). First, the total length must be found in one direction in the middle parallel to the walls. Then in the width direction. Then you have to make calculations for the half goals. Now the half length can be set aside, then the half width, then set aside the half length again so that the lines intersect. However, this point must be presumed inaccurate as it is all done in freehand, and hardly perpendicular / parallel. One must check the length in the opposite direction, the width in the opposite direction, and correct the lines. To be absolutely sure, many craftsmen take cross-purposes (diagonally) to make sure of a precise center point. You have moved ladders a minimum of 3 times. This has to be said to be a complicated process, to find a center point.
Many other commonly occurring survey situations are difficult and / or time-consuming due to these 3 drawbacks, and often require calculator involvement, writing down goals, marking escape lines with spirit levels, etc. requires many measurements and calculations for each point, as well
DK 2017 00500 A1 the challenge of keeping a parallel line. Square meter calculation of wall and ceiling surfaces in a whole property for example material calculation does not seem so efficient either.
Another disadvantage these handheld laser rangefinders have is that one cannot calculate relative angles (angles not associated with a slope from levels), but must shoot to several points individually before it can calculate angles. This is extra difficult when not only measuring angles, but depositing angles on surfaces where a certain angle is desired to be set.
In addition, in the handheld models there is no solution to make the measurement precisely in level or exactly parallel / perpendicular. There is a lack of auto function for this, found only in models on tripods. Although you can orient yourself using the inclinometer, it is so sensitive to hit a spot with your hand that you use a tripod when high precision is required. However, this solution for stands also only applies to level measurements and they still cannot make precise parallel / perpendicular measurements.
In the known handheld laser rangefinders, there is also no safe way to adjust the measurement so that it takes place precisely along an edge, or at a certain desired distance to an edge on, for example, boards. For example, if you have to set up cladding boards on a gable with low ends at both ends, the dimensions change a lot by just a small displacement from the desired line. As a rule, the ratio is approx. 1: 2 depending on the angle, ie if you measure, for example, 3 mm offset from the escape line, the target has changed approx. 6 mm, due to miter on both ends. Often, gable cladding boards have an overlap of e.g. 10 mm, which is why you need to make the measurement exactly 10 mm from the edge, this precise adjustment in the measurement is not possible to make efficiently and accurately. Also, there is no effective solution for adjusting measurements whether to shoot to the most common foot panels and frames, or past these to floor or wall respectively.
One final detail is that the rangefinders have not plotted physical targets / rulers on a surface, for quick deposition of extra targets, in combination with a laser measurement. For example, if a new wall is to be built and you have found the distance where the finished wall surface is desired, the performing craftsman will often mark extra targets from this line. Eg. a line 26 mm from here if there should be two layers of plaster, and one will mark where the rule should stand, as this is the first one to put in wall construction. Therefore, you will need to take an extra measurement, or find a thumbnail rather than marking the relative dimensions from the line. Regularly, such relative extra goals occur for artisans. Furthermore, all smaller targets will be either impossible to accomplish, or cumbersome, which means that measuring tape / thumb is often used for small targets.
DK 2017 00500 A1
All in all, the handheld laser rangefinder is not effective enough for the day-to-day work of executive craftsmen, which causes many craftsmen to continue to use mainly thumb or measuring tape and use the laser rangefinder as a supplement where this makes sense.
The invention provides a handheld laser rangefinder as initially described. Characteristic in that it can measure in opposite, perpendicular and parallel directions at the same time, ie. 0 °, 90 ° 180 °, 270 °, 270 °. Thus, one does not have to take measurements from the endpoint, but achieves flexible positioning and orientation. You can thus at one time orientate yourself to targets left, right, up, down and combined goals. In the invention, point measurements and markings can be made with just one measurement (ie points where two perpendicular targets intersect). One can find in the invention a center point of e.g. a ceiling surface, and find fractional divisions into 2 perpendicular axes at the same time by just one measurement, without the use of a calculator or other aids. You can make M2 measurements at one measurement, also at inclined walls. In accordance with the invention, it is possible, at the same time as a measurement, to check that these are done in parallel, perpendicular or in level, and use a semi-auto function to achieve high precision in this. The invention also provides the opportunity to set angles on materials by one measurement (however, using an external right rail, for example, a spirit level), and to measure most relative angles by one measurement (limited by the range of operation of the lasers). In the invention one can adjust measurements +/- 0-15 mm from the edge of the material. In the invention, measurements can easily be made either for foot panels or past these to floors. The invention also has a physical ruler designed for rapid deposition of smaller targets, individually or in combination with the laser measurement.
This is achieved according to the invention by a laser rangefinder of the kind mentioned above. The invention will be explained in more detail below with reference to the following drawings

Q Rear view of laser rangefinder
As initially described, an invention is provided for a laser rangefinder with inclinometer, characterized by the relationship of 5 laser units in a handheld box (Fig. A). Thus, two laser units are located in the same axis (1, 2) at each end of a box, measuring in precisely opposite directions, is referred to as the main axis (6). Perpendicular to the main axis and substantially at the widest possible spacing, as well as the same distance to the center axis (7), 2 downward laser units (3, 4) are located. In the center of the box at the center axis is a laser unit (5) which also measures perpendicular to the main axis, but upwards. Characteristic that measurements can be made at 0 ° (1), 90 ° (5), 180 ° (2), 270 ° (3, 4). The dimensions of FIG. A is indicative of indication of the size ratio, being essentially a handheld laser rangefinder.
According to FIG. B1 / B2 is the upper surface called the measuring surface (6), this figure also shows the center line (7). In FIG. C, the measuring surface is seen from above. On this surface, as shown here, the center line (1) and measuring lines have been introduced to assist in the setting of targets. The center line is located in the middle at the center axis, and it is at this line and measuring surface that the 5 laser targets measure (exceptions are described later). According to FIG. B1 / B2 is achieved by the laser units (1, 2) being programmed to display measured distance including distance from the center axis (11, 12). The laser units (3, 4, 5) are programmed to display the distance to this upper surface, the measuring surface (13, 14,15). The dimensions of the measuring surface can be either fixed to the top surface of the box in e.g. millimeters, or on a replaceable or reversible rail
DK 2017 00500 A1 to be mounted. This allows for a rail with alternative units of measurement e.g. inches. The essence is that a center dash and measuring dashes are present on this surface. Markings are deposited at the center line, and the dashes can be used for the quick sale of several relative targets from this point, for example. a wall construction. Dimensions smaller than the minimum range of the lasers can also be deposited from this surface.
In addition to the 5 laser targets, and how these refer to the center line and the measuring surface as described, according to FIG. B1 / B2 also be given a total target in the main axis (16) and total target in the center axis (17). This is achieved by programming so that the laser targets (11, 12) are added and will result in the total target in the main axis (16). The programming for the center axis will be the average of (13, 14) added by (15), thus resulting in the total target in the center axis (17). However, in later mentioned menus that do not visually contain these total targets, it is still this calculation method that applies to total targets in the main axis and the center axis.
Thus, as demonstrated by this, in this construction of the laser units, the laser distance meter can be optionally positioned at measurement, and is not forced to make measurements from an endpoint.
In FIG. D and E, the basic measurement principle is illustrated by this construction of 5 laser units in a handheld laser rangefinder. FIG. D shows a correct measurement, while FIG. E shows an incorrect measurement. The laser rangefinder (center bar) is in the drawing located at point (5). The 5 dashed lines (1-5) indicate the measured directions of the 5 laser units (corresponding to the laser units 1-5 in Figures A and B1). When the 2 parallel lasers (3, 4) have the same target, the measurement will be correct ie. parallel or perpendicular (Fig. D). When they have different measurements, the measurement will be incorrect (Fig. E). For measurements in one axis, e.g. a total length measurement in the main axis, the other laser units will act as support targets to ensure the target in the main axis is made at the desired height, and that the measurement is made perpendicular or parallel to a correct measurement, and will not serve as actual targets to be stored . These support measures are especially useful for measurements on ceiling surfaces and floor surfaces where the inclinometer cannot function as a support. When measuring on wall surfaces, one will most often choose that the targets are leveled using the inclinometer.
FIG. D and E also demonstrate how it is possible to find a point using one measurement. As the lasers are continuously measuring, the targets will be constantly updated as the rangefinder moves. As shown in FIG. B1 / B2 can therefore optionally use the measurements to the left (11), right (12), up (15) or down (13,14), depending on which reference is needed, and thus move the distance meter to the desired point. At this point, the rangefinder is moved so that the 2 parallel lasers (3, 4) have the same target (13, 14), thus ensuring as described a correct measurement, and in practice the 2 targets will now
DK 2017 00500 A1 could be perceived as being taken midway between the 2 lasers, ie in the center axis and in the same axis as the upward laser (5). You can thus deduce the point at the center line (7).
Thus, with the 2 parallel lasers (3, 4) one can make sure that measurements are parallel or perpendicular. In combination with the built-in inclinometer (10), one can alternatively make sure that the measurements are level. This is achieved by simple reading, or by the auto function described later.
In FIG. B shows the construction of the laser rangefinder. Navigation buttons (8) are provided containing arrow keys, enter button in the middle, and a return button. These buttons are used to navigate the screen, to select features and menus, or to go back to the latest screen. When the return button is held for approx. 2 seconds, you always return to the home screen. The design of the buttons is indicative here, the essential being that you can navigate effectively in menus and functions. The rangefinder also has a laser button (9). When held for approx. 2 seconds, the unit turns on or off. At one press of the laser button, the lasers and the inclinometer (10) are activated and continuously measure. At the next push of the laser button, the laser targets and the inclination of the inclinometer on that measurement are locked and the lasers are turned off. The screen changes to fig. F, and in this screen you have the option of using the navigation keys to select which target (s) to save, by default, the total target in the main axis is suggested by highlighting this (1). The essence of this screen is that one can check whether the laser measurements and inclination from the inclinometer were satisfactory before saving, or alternatively delete the measurement. The return button can also be programmed here as a shortcut to delete and make a new measurement.
The digital inclinometer is represented, by the numerical value of the slope in degrees from levels (Fig. B2-10). a visual spirit level / pilot stick is recorded and programmed to guide these values as indicative as suggested here. Essentially, a digital inclinometer is represented by numerical values in degrees.
As seen in FIG. B2, representing the home screen with all 5 lasers selected, has 5 icons (18-22) at the bottom of the screen. There is a menu overview (22), a list of saved targets (21), and 3 icons (18,19, 20) each representing variations of the home screen with the option to select fewer active lasers where appropriate. When one of these icons is selected by means of the navigation buttons you enter the respective menu, so if icon (18) is selected, the home screen changes to fig. G with 2 active lasers in the main axis. Selecting the icon (20) changes the screen to FIG. H from which laser measurement with 1 active laser as we traditionally know it is an option.
In FIG. G with 2 active lasers, programming is only done with these targets from the main axis in the same way as previously described with 2 laser targets for the center axis (1, 2) and a total target in the main axis (3).
DK 2017 00500 A1
This feature is characteristic in that it can be measured in two opposite directions (180 °) in the same axis, without the need to take measurements from an end point, but with optional placement. Since this menu does not have perpendicular measurement, it will typically be useful for measurements in one axis along the escape surfaces, e.g. measurements along wall and ceiling or wall and floor, or e.g. along window frames / door frames or the like where support measures are not needed.
As seen in FIG. You can also select just one active laser. This accommodates a very traditional distance measurement as already known, as this can initially meet simple measurements from an endpoint. In this function, 3 targets have been selected, so that (1) is programmed to display the distance measurement to the first edge of the box. The center target (2) is programmed to display the distance measurement including the distance to the center axis. The dimension of the opposite edge (3) is programmed to show the distance measurement including the entire length of the box. As artisans are traditionally used to take measurements with a single laser meter from the edge of the rangefinder box, it is essential that these targets occur to avoid confusion about where the measurement in this menu is taking place. Further, the target at the end of the box (3) is programmed to be clearly highlighted and also programmed to be selected by default when the targets are locked before saving as in principle previously described. Already known developed functions from measurement by one laser can, as it seems relevant, also be programmed into the laser rangefinder based on this possibility.
In FIG. B2, G, H see an auto function (23). With this button you can activate an auto function by taking the measurement (half) automatically in levels. Instead of a costly build with e.g. motor-driven lasers, the challenge here is solved the hallmark of programming. The auto button (23) is programmed so that when activated by the navigation buttons, the normal laser button (fig. B-9) is deactivated. The programming is carried out so that when this function is selected, the lasers and the inclinometer are activated, as it would normally have done at the first push of the laser button. As soon as the rangefinder detects that the inclinometer is showing levels, it automatically locks all targets in the same way that the laser button would normally achieve at second press. It is programmed with as high precision at the inclinometer as is practically possible to achieve, keeping in mind that in this function the user himself has to guide the rangefinder across levels with calm movements, the definition of which is semi-automatic.
In FIG. B2 where all 5 lasers are selected, one must also be able to choose between auto-levers or autoparallel function, e.g. via a pop-up window when the auto button is selected. In auto-parallel, programming is basically the same as described in auto-leveling. Only difference during this programming will be that after activation, the rangefinder is programmed to that moment
DK 2017 00500 A1 it detects the 2 downward lasers have an identical measurement, it automatically locks all targets, as opposed to registration via the inclinometer at auto-levels. Thus, this semi-auto function can also be used to obtain a parallel or perpendicular measurement. During this function, the user must guide the rangefinder towards uniform targets at the 2 downward parallel lasers (13,14).
In FIG. I and J see a menu for fractions. This menu is characterized in that it can calculate fractional divisions in the main axis and the center axis at the same time, so that the divisions can be deposited at the center line, without the use of calculators or other aids. Fractions are represented for the main axis (1) and the center axis (2). When selecting a fraction in an axis, it is highlighted (3, 4). Also, an icon appears for each axis with information for the main axis (5) and for the center axis (6). When using the menu, the lasers continuously measure as normal. The programming of the information in the main axis (5) works such that when a fraction is selected in the main axis (3), it calculates on the basis of the total target in the main axis, all the fraction classifications in the fraction. 1/5, 2/5, 3/5, 4/5 for internal calculation for the information. The fractions are then calculated from the left laser meter and to the center line for internal use. Next, the icon (5) is programmed to automatically display the fraction closest to the center line. In the example of fig. I, 3/5. It is also programmed to show the distance to the fraction, as well as to show an arrow in the direction the distance meter must be moved to hit this fraction. In the center axis the principle is the same, here the total target in the center axis is used for internal calculation. The fractions are then calculated from the downward lasers (the average of the two targets as previously described), and to the measuring surface. It is programmed to automatically display the fraction closest to the measuring surface, as well as the distance to the fraction and an arrow in the direction the distance meter must be moved so that the fraction can be deposited at the center line of the measurement surface. This information is displayed in the center axis icon (6). It is recommended that you also see the laser targets as normal, so that you can combine targets and fractions as needed, and check that the distance meter is kept parallel to the 2 downward lasers.
In FIG. J is an example of when you have positioned the odometer correctly at the fractions. As indicated herein, it must be programmed to be evident once the point is found, as suggested here by color indication (5, 6).
There is also a button called define area (7), in which an opportunity must be programmed to lock the laser meter on a specific target, which you can. shoots from this menu so that it uses this target as a starting point for the fraction calculation. Likewise, one must subsequently be able to choose which / (which when both axes are used) of the lasers from which fractions are calculated. So that the laser meter after the target is locked, for example only refers to the right laser. This can be used when you want the divisions to follow an escape line eg. between columns, but where you don't have an actual point
GB 2017 00500 A1 to shoot at both ends, but only at one end. Furthermore, an opportunity must be programmed to make an offset at the lasers you want, so that the fraction calculation deducts this offset before the calculation. This is useful when the divisions must follow e.g. a kitchenette that does not go out to the end walls, where you want offset from the kitchen and to the end wall.
In FIG. K, L, M, N, O are the menus for M2 (square meter) calculation. On the basis of the distance meter structure, one can obtain M2 calculation by one measurement also by inclined walls, characterized by M2 calculation on the basis of perpendicular measurement in 2 axes simultaneously. In these menus, it is not necessary to display the respective laser targets, however these are used for the M2 calculation. It is recommended to display the 2 parallel laser targets to help keep the rangefinder parallel. In FIG. K is a standard menu for M2. The menu is programmed to find M2 (1) by multiplying total dimensions in the main axis and the center axis.
Fig. L shows that alternatively one or more of the 4 areas can be chosen divided by the center axis and the measuring surface (parallel to the main axis). This is achieved by multiplying the 5 normal laser targets in the respective manner for each field. For example, at the highlighted field (1), the right laser target (Figs. B2-12) is multiplied by the upward laser target (Figs. B2-15), and so on.
In FIG. M sees the possibility of M2 calculation at inclined walls. In this menu it is essential that the user positions the rangefinder vertically as the image where the lasers shoot in the respective corners. Thus, in this menu, only the 2 lasers in the main axis (1, 2) (corresponding to Figures A -1, 2) and the center laser (3) (corresponding to Figures A - 5) are active, and not the 2 parallel lasers. The result is obtained by adding the M2 calculation for the square field, with geometric M2 calculation for the triangular field. Too high precision can be added to the smaller area the lasers of physical limitations can not measure. Since the lasers of the main axis cannot measure completely into the corners, this can be added by simple calculation, knowing the distance from the main axis to the distance meter edge.
In FIG. You can also select one of the two fields (using the navigation keys) divided by the center laser (3). The principle of calculation is the same as described, only for the selected field.
In FIG. O See M2 calculation at 2 inclined walls. The user must position the odometer horizontally so that the center laser (5) shoots up at the tip of the triangle (6) while the lasers in the main axis (1, 2) shoot into the corners (3, 4)). Then M2 is calculated based on the objectives of the 5 lasers.
In FIG. P shows how the distance meter can calculate angles by one measurement, characterized by geometric calculation by the difference between the measurements of the 2 parallel lasers. Since a right-angled triangle (1) is formed by the difference between the targets (2) of the two lasers and the distance between them
DK 2017 00500 A1 the 2 lasers are fixed (3) an angle can be calculated using Pythagoras. When depositing angles on materials, the user must use a straight rail, for example. a spirit level (4).
The rangefinder can, as illustrated in FIG. Q. make measurements precisely at the main axis laser meters (1, 2), or offset from this axis. Characteristic of 2 retractable adjustable rails (3, 4) on the back of the rangefinder at each end. The rails are designed so that they can be tilted out from the rear and locked in a 90 degree position from the rear, and can be adjusted to the main axis indicated by the 0 point on the scale (7) or offset from the main axis, recommended up to 15mm. Thus, measurements can be made smoothly with materials, or offset by e.g. overlap of boards by gable trim.
In addition, 2 similar foldable (non-adjustable) rails (5, 6) are constructed around the middle, so that when all 4 rails (3, 4, 5, 6) are knocked out, they function together as 4 feet or spacers. The length of the rails is designed so that when they are knocked out and the spacer is held up against a wall surface, the lasers will, as a minimum, shoot past commonly used foot panels / frames
