1 and 2, the multipurpose ruler 100 according to an embodiment of the present invention includes a rotation shaft 110, a pair of length measuring units 131 and 141, and an angle measuring unit 150.

The rotation shaft 110 provides a center axis around which the length measuring units 131 and 141 and the angle measuring unit 150 rotate.

The rotation shaft 110 may be coupled to a center portion of the length measuring part 131, 141 and the center of the angle measuring part 150.

One end of the pair of length measuring units 131 and 141 is connected to the rotation shaft 110.

In one embodiment of the present invention, when the length measuring parts 131 and 141 each have a rectangular plate shape, the corners of the length measuring parts 131 and 141 may be connected to the rotation shaft 110. That is, through grooves are formed in the corners of the length measuring units 131 and 141, and the rotation shaft 110 is inserted into the through grooves, so that the length measuring units 131 and 141 and the rotating shaft 110 are formed. Can be fastened to each other.

In another embodiment of the present invention, fastening portions (not shown) having through grooves that may be connected to the corner portions of the length measuring parts 131 and 141 may be disposed. That is, as the pair of length measuring units 131 and 141 have one fastening unit connected to each other, and the rotating shaft 110 is fastened to the through groove, the length measuring units 131 and 141 and the rotating shaft 110 are connected. Can be fastened to each other.

In one embodiment of the present invention, any one of the pair of length measuring unit (131, 141) to measure the length in meters, while the other is to measure the length in inches each ruler respectively Can provide. Alternatively, both of the pair of length measuring units 131 and 141 may each provide a ruler to measure the length in meters.

 The angle measuring unit 150 has a semicircular shape. The angle measuring unit 150 may measure 180 degrees according to the shape of the semicircle. The angle measuring unit 150 includes a semicircle and a straight portion. The center of the straight portion is fastened to the rotation shaft 110. For example, when the length measuring part 131, 141 is fastened to the rotation shaft 110 at the center of the straight part and the length measuring part 131, 141 contacts each other, the angle measuring part 150 is any one of the length measuring part 131, 141. It can be contacted to the upper surface of.

In one embodiment of the present invention, when the angle measuring unit 150 has a semi-circular shape, a through groove is formed in the center of the straight portion of the angle measuring unit 150 and the rotating shaft 110 is formed in the through groove. Can be fastened. That is, a through groove is formed at the center of the straight portion of the angle measuring unit 150, and the rotation shaft 110 is inserted into the through groove, so that the angle measuring unit 150 and the rotating shaft 110 are fastened to each other. Can be.

In another embodiment of the present invention, a fastening part which may be connected to the center of the straight part of the angle measuring part 150 and the through groove is formed may be disposed. That is, as one fastening part is connected to the center of the straight part of the angle measuring part 150 and the rotating shaft 150 is fastened to the through groove, the angle measuring part 150 and the rotating shaft 110 may be fastened to each other. have.

Therefore, the angle measuring unit 150 rotates the angle measuring unit 150 and the length measuring units 131 and 141 about the rotation axis 110 so that the angle measuring unit 150 measures the angle of the object and the length measuring units 131 and 141 rotates the object. The length of can be measured effectively.

In an embodiment of the present invention, at least one of the length measuring parts 131 and 141 may have a first groove 135 formed therein along its long axis. The writing instrument 170 or the blade 160 may be mounted in the first groove 135.

An example of the writing instrument 170 may include a pencil lead. As the pencil lead is mounted in the first groove 135, the multipurpose ruler 100 of the present invention may function as a writing instrument 170.

In another embodiment of the present invention, the second groove 145 may be formed in the length measuring unit 141 in which the first groove 135 is not formed. The blade 160 may be mounted in the second groove 145. As the blade 160 is mounted in the second groove 145, the multipurpose ruler 100 may function as a knife for cutting an object.

3A is a partial front view illustrating the coupling structure in which the blade of FIG. 1 is coupled to the first groove. 3B is a partial front view illustrating a coupling structure in which the writing instrument of FIG. 1 is coupled to the second groove.

The first and second grooves 135 and 145 may be formed in a crisscross shape along the long axis, respectively. In addition, pressing portions 165 and 175 may be formed to be connected to one end of the blade 160 or the writing instrument 170 and to hold the hand by the user to press the blade 160 or the writing instrument 170. Can be. The pressurizing portions 165 and 175 extend from the bodies 166 and 176 and the bodies 166 and 176 protruding upward from the pair of length measuring units 131 and 141. It may include connections 167 and 177 having a wide horizontal cross-sectional area. The connecting portions 167 and 177 may be inserted into the centers of the first and second grooves 135 and 145 formed in the cross shape so as to detach or attach the blade or the writing instrument along the long axis.

In an embodiment of the present invention, each of the length measuring parts 131 and 141 is formed with a first groove 135 and a second groove 145 extending along a long axis. The blade 160 and the writing instrument 170 are mounted in the first groove 135 and the second groove 145, respectively. Accordingly, the multipurpose ruler 100 may perform a knife function for cutting an object and a writing instrument function for writing on the object.

While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
