Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring device for measuring the distance between objects by using distance measuring means.

[0002]

2. Description of the Related Art When measuring a distance from an object A to an object B, for example, one person sets a tip of a measure at a measurement reference position of the object A, and another person measures a dimension at a measurement point of the object B. However, such a method requires two people and takes time. Further, it is necessary to crawl the measure on the floor surface, which may cause physical pain, or the floor surface may be injured due to scattering of building tools and the like. In order to solve these problems, conventionally, there is known a measuring device that measures a distance by a distance measuring unit including a light emitting element and a light receiving element. This type of measuring device projects light from a light emitting element toward the object B from the reference position of the object A, and receives reflected light at the light receiving element to detect the object AB.
It measures the distance between them.

[0003]

However, in the above measuring device, the measurer needs to bring the measuring device to the reference position of the object A or the object B. If left in place, it will be difficult to reach the reference position object. Further, if the object serving as the reference position is far away, it takes time and labor for measurement. Furthermore, when trying to measure the distance between the objects AB, it is necessary to first measure the distance to the object A, then measure the distance to the object B, and add the two measured values by the measurer. Work efficiency is low. Further, if the reference position of the measuring device moves during these two measurements, an error occurs, and there is a problem that the distance between the objects cannot be accurately measured. The present invention solves the above-mentioned problems, and when measuring the distance between objects, the distance between the objects can be easily and accurately measured, which reduces the number of measurement steps and improves work efficiency. It is an object of the present invention to provide a measuring device that can be achieved.

[0004]

In order to achieve the above object, the present invention provides a measuring device for measuring a distance to an object by a distance measuring device, wherein the distance measuring device is provided on both side surfaces of the device. It is provided with a control device for adding the distance to the object facing each distance measuring means measured by the distance measuring means and the distance between these distance measuring means.

[0005]

According to the above construction, the measuring device is set at an appropriate place between the objects, the distances to the respective facing objects are measured by the respective distance measuring means, and the distance between the respective measurement results and the distance measuring means is measured. The distance and the distance between the objects can be measured by adding the distance and the control device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the appearance of the measuring device. FIG. 2 shows a schematic block configuration of the measuring device. In FIG. 1, distance measuring units 2 and 3 each including a combination of a light emitting element and a light receiving element are provided on both side surfaces of the main body of the measuring device 1, and a display unit 4 for displaying a measurement result and the device 1 on the upper surface of the main body. A level 5 indicating the levelness is provided, and a measuring button 6 for on / off controlling the operation of the device 1 is provided on the front surface of the main body. In FIG.
The control device 7 adds the respective measurement values measured by the distance measuring units 2 and 3 and the distance between the distance measuring units 2 and 3, and
Control the entire device 1. The distance measuring units 2 and 3 of this embodiment
Is a known active triangulation method and its detailed description is omitted. The control device 7 includes a distance measuring unit 2 and 3, a measurement button 6, a power supply unit 8 for supplying power, a memory 9 for storing the measurement result of the control device 7, a display unit 4 and data to a terminal such as a personal computer. Is connected to the output unit 10.

Next, the measuring operation of the apparatus 1 will be described with reference to FIG. The device 1 is set using the tripod 11 at an appropriate position between the wall A and the wall B, and the device 1 is adjusted so that the spirit level 5 becomes horizontal. When the measurement button 6 is pressed, the distance measuring units 2 and 3 simultaneously function and the distance measuring unit 2 measures the distance to the wall A.
The distance measuring unit 3 measures the distance to the wall B, respectively. After that, the control device 7 adds the distance to the wall A, the distance to the wall B, and the distance between the distance measuring units 2 and 3 stored in advance, and displays the addition result as a linear distance between the walls AB. The data is output to the section 4, and one measurement is completed. It should be noted that measurement is continued while the measurement button 6 is held down, and the latest measurement value is held and displayed when the measurement button 6 is released. In this way, the present device 1
When the measurement is performed by arranging between the walls AB, the distance measuring units 2 and 3 measure the distances to the opposing walls A and B, respectively. You don't have to. Therefore, the working time can be shortened. It should be noted that the present apparatus 1 can be similarly measured even when the present apparatus 1 is brought into contact with the wall A as shown in FIG.

Further, the present apparatus 1 can measure the straight line distance between objects without using the tripod 11. The minimum dimension search mode (minimum mode) will be described with reference to FIG. FIG. 5 shows a case where the distance between the walls AB is measured by the device 1 without using a tripod. First, the minimum mode is selected by a selection button (not shown), the device 1 is held in a hand (not shown), and the measurement button 6 is pressed and shaken in the directions indicated by arrows a and b. At this time, the measurement points of the walls A and B measured by the distance measuring units 2 and 3 move variously as shown by the alternate long and short dash line, and accordingly, the measurement result changes sequentially as shown in the graph of FIG. . After the measurement for several seconds, the control device 7 selects and displays the minimum value at the time of measurement as the linear distance between the objects AB. As described above, in the minimum mode, it is possible to easily measure the distance between objects with high accuracy even when there is no tripod. Therefore, it is usually difficult to accurately measure the distance between objects due to camera shake when the measurement device is held in the hand, but with the present device 1, the measurement device is held in the hand and measured. There is no problem.

FIG. 7 shows an embodiment in which colored light is applied to a portion of the apparatus 1 whose distance is measured from both sides. In this embodiment, a light source for irradiating a distance measurement area with chromatic color light may be provided separately from the light emitting element for distance measurement. Also,
It is also possible to adopt a configuration in which the reflected light of the irradiation light is used for distance measurement. By irradiating the distance measuring portion with chromatic color light in this manner, it becomes easy to understand where the distance measuring units 2 and 3 are measuring. The present invention is not limited to the above embodiment, and various modifications can be made. For example, as the distance measuring units 2 and 3 in the above embodiment, an element that emits ultrasonic waves or a laser beam may be used.
A passive method may be used in which distance measurement is performed only with constant light.

[0010]

As described above, according to the present invention, the distance measuring means provided on both side surfaces of the apparatus main body measures the distance to the object facing each distance measuring means, and the distance measuring means is used. Since the distance between the objects is obtained by adding the distances between the objects, it is possible to measure the distance between the objects with high accuracy simply by positioning the measuring device between the objects and performing a simple operation. Therefore, it can be measured by one person, the number of measurement steps can be reduced, and it takes only a few seconds to measure one dimension, and the measurement time can be shortened. Since it is not necessary to perform the measurement, the workability can be improved and the safety can be improved because the measurement can be performed at a safe place even at the construction site.
