1. Field of the Invention
The present invention relates to a measuring device, and more particularly to a measuring device for measuring the size of a workpiece to be measured.
2. Description of the Related Art
A conventional ruler is used to measure the size of a workpiece, such as a cloth, a paper pattern or the like. The conventional ruler includes a transparent ruler body made of acrylic material, and a plurality of scales mounted on the ruler body. However, the user has to measure the size from a start point of the scales, thereby wasting the measuring time and the manual work. In addition, the marking lines of the scales are too clear to shelter the user's sight of view, so that the user cannot align the marking lines of the scales exactly. Further, in the metric measuring system, the basis unit of each of the scales is one millimeter (1 mm). Thus, the scales have too many marking lines, so that the scales are made vague and the user cannot distinguish the scales easily, thereby causing inconvenience to the user in measurement of the size of the workpiece.
The primary objective of the present invention is to provide a measuring device that is used to measure the size of the workpiece at any direction and any start point, thereby saving the measuring time and the manual work.
Another objective of the present invention is to provide a measuring device, wherein the counting numbers on the scales have a two-dimensional corresponding manner so that the measuring device can obtain the size of the workpiece to be measured instantaneously from left to right or from right to left without having to rotate or change the direction of the ruler body.
A further objective of the present invention is to provide a measuring device, wherein the measuring device can obtain the size of the workpiece directly without needing further calculation.
A further objective of the present invention is to provide a measuring device, wherein the vertical line of a specified scale is provided with a line segment marking so that the user can mark the scale quickly, thereby enhancing the measuring velocity and efficiency.
A further objective of the present invention is to provide a measuring device, wherein each of the intersecting points of the horizontal marking lines and the vertical marking lines is indicated by a specified sign and phantom lines so that the marking lines produce an extended and concentrated effect to present an outstanding appearance, thereby preventing the marking lines from sheltering the user's sight of view, and thereby facilitating the user aligning each of the intersecting points of the marking lines exactly.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
In the preferred embodiment of the present invention, the counting numbers 4 on the scales 2 have a two-dimensional corresponding manner and adopt two measuring units, including the metric measuring system (such as 16 cm) and the British measuring system (such as 16 in). The counting numbers 4 are numbered from one to fifteen (1–15) and arranged from left to right, wherein each of the counting numbers 4 has a corresponding numeral which is located under the respective the counting number 4 for measurement of different directions. For example, one (1) is corresponding to fifteen (15), two (2) is corresponding to fourteen (14), three (3) is corresponding to thirteen (13), etc., and fifteen (15) is corresponding to one (1). Thus, the measuring device can obtain the size of the workpiece to be measured instantaneously from left to right or from right to left without having to rotate or change the direction of the ruler body 1. In addition, the measuring device can obtain the size of the workpiece to be measured directly without needing further calculation.
In addition, in the metric measuring system as shown in

Accordingly, the counting numbers 4 on the scales 2 have a two-dimensional corresponding manner so that the measuring device can obtain the size of the workpiece to be measured instantaneously from left to right or from right to left without having to rotate or change the direction of the ruler body 1. In addition, the measuring device can obtain the size of the workpiece directly without needing further calculation. Further, the measuring device is used to measure the size of the workpiece at any direction and any start point, thereby saving the measuring time and the manual work. Further, the vertical line of a specified scale 2 is provided with a line segment marking so that the user can mark the scale 2 quickly, thereby enhancing the measuring velocity and efficiency. Further, each of the intersecting points of the horizontal marking lines 3 and the vertical marking lines 3 is indicated by a specified sign and phantom lines so that the marking lines 3 produce an extended and concentrated effect to present an outstanding appearance, thereby preventing the marking lines 3 from sheltering the user's sight of view, and thereby facilitating the user aligning each of the intersecting points of the marking lines 3 exactly.
Although the invention 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 scope 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.
