Description

{GRADUATED RULER HAVING A CUTTER}

The present invention relates to a ruler of a cutting function which is capable of cutting an object to be cut straight to an exact length and is easy to carry and use.

Generally, since the knife-type cutter is intended to be used for precisely cutting the object to be cut such as paper or plastic to a length, a separate scale is required for accurately adjusting the cutting length when the knife-type cutter is used for learning or working.

However, since the ruler must be provided separately from the cutter, the user is inconvenient to use the cutter, and in particular, when the user is immature in using the knife-type cutter such as a student or a child,

In order to solve this problem, a technique of integrating a knife (knife-type cutter) and a ruler has been proposed (Registration Practical Utility Model No. 20-0342922; hereinafter referred to as "Prior Art").

However, in the conventional art, since the cutting object (paper) 50 is inserted between the ruler body 10 and the blade supporting portion 20 and the inserted object to be cut is cut by the blade supporting portion 20, And the cutting target can be cut only when the user directly moves the cutting target itself. Therefore, when the cutting object is cut by the conventional technique, the cutting object is bent or deviated from the insertion position of the blade support portion 20 during movement of the ruler body 10, the blade support portion 20, or the cutting object, There was a problem that I could not do.

In addition, since the knife-type cutter is capable of cutting various positions of the object to be cut, the knife-supporting portion 20 is engaged only with the sliding groove 12 at the position specified in the ruler body 10, There was also the problem that there were restrictions on location.

On the other hand, since the prior art has only a knife-type cutter, the object to be cut is limited to paper or the like. Therefore, in the case where the plastic or the like needs to be cut, there is a limitation that the conventional technology can not be used.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view explaining an embodiment of a ruler according to the present invention, and FIG. 2 is a plan view showing an embodiment of a connection between a reference element and a connector of the ruler.

The ruler of this embodiment includes a reference member 100, a connector 200 movably connecting the cut module 300 and the reference piece 100, and a cutting module 300 cutting the cut object.

The reference mark 100 has a straight mark 110 as shown in FIG. 2, and a unit of length is displayed along the edge. Accordingly, the user can draw a line or measure the length according to the scale mark 110. [

The connector 200 includes a main body 210 having one end connected to the reference member 100 in parallel and a connecting rail 211 formed along the longitudinal direction at the other end, And a connector 220 connected to each other.

The main body 210 is formed with both ends 212 and 212 'for preventing the cutting module 300 from stopping and departing from both ends of the connecting rail 211 when the connecting rail 211 ends. The main body 210 of the connector 200 has a scale marking 213 such as a scale mark 110 of the reference mark 100 displayed along the connection rail 211 so that the moving length of the cutting module 300 is changed by the user .

The connecting member 220 integrally connecting the reference member 100 and the connector 200 is formed by inserting the bracket protruding from the main body 210 of the connector 200 into the reference member 100, And the bracket and the reference member 100 are fastened to each other with bolts or pins but the connection member 220 is not limited thereto and the reference member 100 and the connector 200 can be integrally connected Various modifications may be made without departing from the scope of the following claims.

FIG. 3 is a side view showing the operation of the reference between the reference and the connector of the scale.

The connecting body 220 of the present embodiment is rotatably connected to the main body 210 through a hinge 222. 3 (b), the main body 210 rotates about the hinge 222 of the connector 220 so that the user can use the cutting module 300 to perform a tilting operation The object can be precisely cut.

FIG. 4 is a perspective view explaining the configuration of the cutting module, and FIG. 5 is a front view showing an operation of the cutting module shown in FIG.

The cutting module 300 of the present embodiment includes a moving body 310 that is movably engaged with and connected to the main body 210, a rotating body 310 rotatably connected to the moving body 310, And includes a whole body 320 and a heat wire cutter 330 that generates heat for cutting the object to be cut T. [

The moving body 310 of the present embodiment includes a base 311, a coupling 312 protruded from the base 311 so as to be engaged with the coupling rail 211 of the main body 210, A supporter 314 for supporting the rotator 320 and restricting its rotation angle and a spring 315 for elastically rotating the rotator 320 from the supporter 314.

The base 311 divides the rotating body 320 so that the rotating body 320 rotates smoothly without interference with the body 210. To this end, one surface of the base 311 facing the rotating body 320 preferably has a flat surface shape. The indexing grooves 311a are formed on the upper surface of the base 311 so that the movement length of the cutting module 300 can be checked based on the scale markers 110 and 213 formed on the reference marker 100 and the connector 200, .

The connection hole 312 is protruded from the base 311 so as to be engaged with the connection rail 211. In this embodiment, the connection rail 211 has a groove shape, and the connection hole 312 is inserted into the connection rail 211 to form a protrusion. In addition, the connecting portion 312 inserted into the groove-shaped connecting rail 211 has a neck portion having a relatively narrow width, and the connecting rail 211 also has a bottleneck structure corresponding thereto. The connecting port 312 is moved along the longitudinal direction of the connecting rail 211 without being separated from the connecting rail 211. [ In this embodiment, the connection rail 211 is of a groove shape and the connection hole 312 is a protrusion shape. However, the connection rail 211 may be a protrusion shape and the connection hole 312 may be a groove shape.

The connection shaft 313 is a medium for connecting the rotation body 320 to rotate based on the base 311. To this end, the connection shaft 313 protrudes from the base 311, and the rotation body 320 forms a rotation groove 322 in which the connection shaft 313 is engaged. In this embodiment, the connection shaft 313 protrudes from the base 311 and the rotation shaft 322 is engaged with the connection shaft 313 in the rotation body 320. However, Various modifications can be made.

The supporter 314 protrudes from the base 311 so as to limit the rotation angle of the rotating body 320. Therefore, the rotating body 320 rotates only within the range limited by the supporter 314. The supporter 314 is disposed below the rotating body 320 connected to the base 311 so that the rotating body 320 does not rotate below the point where the supporter 314 is located. 5 (b), the supporter 314 prevents the body of the knife-shaped cutter 323 formed on the rotating body 320 from coming into direct contact with the cutting target T .

The spring 315 elastically supports the rotating body 320 between the rotating body 320 and the supporter 314. In this embodiment, the spring 315 is U-shaped, but various types of spring shapes and materials such as a coil spring may be used.

The rotating body 320 of the present embodiment includes a rotating shaft 321 rotatably connected to the moving body 310 via a rotating shaft 313 and a rotating groove 322 rotatably engaged with the rotating shaft 313, A knife-shaped cutter 323 for detachably mounting the knife 324, and a wrapper 326 for attaching / detaching the heat wire cutter 330 to / from each other.

The rotating shaft 321 constitutes the base of the rotating body 320 and is rotatably connected to the moving body 310 through mutual meshing of the rotating shaft 313 and the rotating groove 322.

The knife-shaped cutter 323 has a shape capable of removing and attaching a common knife 324, and a knob 325 connected to the knife 324 is protruded so that the user can easily remove the knife 324. Accordingly, the user can remove the knife 324 from the knife-shaped cutter 323 by using the handle 325, and cut the cutting target T with the knife 324 positioned on the same line with the zenithal core 331 Or the cutting position can be displayed on the surface of the object T to be cut.

The wrapper 326 protrudes from the upper end of the knife-shaped cutter 323, and removes the heat-wire cutter 330. Accordingly, the user can insert the hot wire cutter 330 into the wrapper 326 to cut the cutting target T based on the knife-shaped cutter 323 when the hot wire cutter 330 needs to be utilized.

The heat wire cutter 330 of the present embodiment is a general pen-shaped cutter, and the protruding core 331 is brought close to the cutting target T to cut the cutting target T. Since the hot wire cutter 330 is a well-known technology, its structure, structure, and operation method will not be described.

The cutting module 300 described above allows the user to cut the cutting target T precisely while moving according to the guidance of the reference person 100 and the connector 200. [ At this time, the rotating body 320 of the cutting module 300 according to the present embodiment is elastically moved upward from the cutting target T by the spring 315 as shown in Fig. 5 (a), so that the knife- 323 and the heat core 331 of the hot wire cutter 330 are separated from the cutting target T and the cutting process is not performed on the cutting target T in a state in which the user does not operate the knife 324 and the heat core 331 of the hot wire cutter 330 . 5 (b), the knife-shaped cutter 323 and the hot-wire cutter 330 are cut off from the cutting target (T) The knife 324 of the knife-shaped cutter 323 comes into contact with the object to be cut T and the core 331 of the heat-wire cutter 330 comes close to the object T to be cut. As a result, the corresponding position of the cutting target T is cut by the knife 324 and the core 331. For reference, the knife 324 can be displayed in a straight line while moving the cutting position of the cutting target T, and the heat core 331 of the heat wire cutter 330 heats the cutting target T along the display to cut it .

5 (a), the spring 315 pushes up the rotating body 320 by its own elastic force, and the knife 324 (see FIG. 5 And the core 331 are separated from the object to be cut T.

FIG. 6 is a perspective view explaining another embodiment of the connection between the reference element and the connector of the scale according to the present invention, FIG. 7 is a plan view showing the operation of the reference element, the connector and the cutting module shown in FIG. 6 .

Since the connector 200 of the present embodiment has a limitation on its own length, the cutting module 300 moving along the connector 200 moves straight within the length of the connector 200, You can cut straight. However, if the length to be cut by the user in the cutting target T is longer than the length of the connector 200, the user can not cut the cutting target T at a time, Must be repeated several times with manual movement. Of course, in this process, there is a problem that the reference position 100 and the connector 200 change positions and the cutting reference can not be maintained straight.

In order to solve this problem, the reference member 100 and the connector 200 are movably connected to each other. For this purpose, the connector 220 'for connecting the reference member 100 and the connector 200 And a connection padding 221 'and a guide line 222'. Here, the connection padding 221 'is protruded from the reference member 100 or the connector 200, and the guide line 222' is a groove type for movably accommodating the connection padding 221 '. In this embodiment, the connection shim 221 'is formed along the longitudinal direction of the reference member 100, and the guide line 222' is formed along the longitudinal direction of the connector 200.

The reference member 100 and the connector 200 are movably connected to each other through the connecting body 220 'of the present embodiment. Therefore, The cutter module 300 may be moved while the reference member 100 is stopped and the cutter module 300 may be moved to the cutting target T by moving the connector 200 and the cutter module 300, (200). In addition, only one or more of the reference member 100, the connector 200, and the cutting module 300 may be moved. 7 (b), when the user cuts the cutting object T to a length longer than the length of the connector 200, the connector 200 and the cutting module 300 are moved together to perform a cutting operation, and when the limit of the reference member 100 is reached, the cutting module 300 is moved based on the connector 200 to perform a cutting operation. Accordingly, the user can accurately move the cutting module 300 with a length corresponding to the length of the reference member 100 and the connector 200, and the user can move the cutting module 300 with a length equal to or longer than the length of the reference member 100 and the connector 200 The cutting target T can be cut.

FIG. 8 is a perspective view explaining another embodiment of the connection between the reference and the connector of the scale according to the present invention, and FIG. 9 is a sectional view showing the operation of the linker shown in FIG.

The reference member 100 and the connector 200 of the present embodiment are movably connected to each other along the longitudinal direction. Thus, as described above, the cutting module 300 moves to a length longer than the reference member 100 or the connector 200 and can perform the cutting operation.

However, in order to perform such an operation, it is troublesome and inconvenient for the user to hold both the connector 200 and the cutting module 300 together, and inconvenience may arise in this process.

In order to solve this problem, the present embodiment allows the user to stop the position of the connector 200 relative to the reference member 100 while adjusting various positions of the connector 200. For this purpose, the connector 220 ' 223).

To be more specific, the connection shim 221 '' of this embodiment has a tubular shape having a hollow 221a, and a plurality of through holes 221b having a hollow 221a are formed on the circumferential surface. In addition, the brake pad 221c is fixed to the through hole 221b at one end so as to constitute a brake pad 221c of a friction material which performs a wing motion to the inside and the outside of the hollow 221a.

The fixed padding 223 has a rod 223a which is rotatably inserted into the hollow 221a of the connection padding 221 "and a rod 223a which is connected in line with the rod 223a and rotates along the rotation of the rod 223a And a handle 223c disposed at an end of the fixed shim 223 so as to be operated by the user for rotation of the rod 223a is constituted by a presser bar 223b having a protrusion for pushing the brake pad 221c to the outside, The rod 223a is rotated by the operation of the user's handle 223c while being inserted into the hollow 221a of the connection padding 221 ". At this time, the pressing rod 223b also rotates the rod 223a And then rotates in the hollow 221a. The pressure pad 223b is disposed at a position in parallel to the through hole 221b of the connection padding 221 "and the through hole 221b is formed with the brake pad 221c which performs the wing motion. As shown in the drawing, the projecting portion of the presser bar 223b does not abut against the brake pad 221c, and the brake pad 221c is recessed from the through hole 221b into the hollow 221a, So that the guide line 222 'can smoothly move along the connection padding 221' 'without interference. 9 (b), the protrusion of the presser bar 223b presses the brake pad 221c and presses the through hole 221b, as shown in Fig. 9 (b). When the user presses the handle 223c to turn the presser bar 223b, The brake pad 221c brakes the guide line 222 'in close contact with the inner surface of the guide line 222'. That is, the standardizer 100 and the connector 200 connected to each other through the connector 220 'can not but maintain the current layout. Of course, when the user manipulates the handle 223c to adjust the position of the projection of the presser band 223b, the brake pad 221c loses the braking pressure, and the user moves the reference member 100 and the connector 200 to each other To adjust the layout.

In order to increase the braking efficiency of the brake pads 221c, the present embodiment may be arranged along a plurality of connection pads 221 ", or two or more may be arranged along the circumference of the same position as in the present embodiment. The brake pads 221c may have a tapered thickness so that the brake pads 221c may be tilted in the thickness direction of the brake pedal 223b, It is preferable that the brake pad 221c at the position is projected largely from the peripheral surface of the connection padding 221 ".

While the present invention has been described in connection with what is presently considered to be practical 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.
