2 is a perspective view of a safety-enhanced cutter knife according to an embodiment of the present invention.

2, the safety-enhanced cutter knife according to an embodiment of the present invention includes a main body case 10, a guide member 20, a blade main body portion, a safety case 40, a hinge member 50, (60).

The main body case 10 is provided with a guide rail 110 for sliding the blade main body portion as means for receiving the blade main body portion.

The guide member 20 is slidably coupled to the guide rail 110 formed in the main body case 10 and the user operates the guide member 20 to push or pull the guide member 20 Thereby sliding the blade main body portion.

The blade main body portion is accommodated in the main body case 10 while being detachably coupled to the guide member 20. When the user operates the guide member 20, the blade main body portion is slid with the guide member 20. [

The safety case 40 is hinged to the main body case 10 through the hinge member 50 and is provided with a blade protrusion groove 410 for protruding the blade main body 30 outwardly from the blade main body 30, And functions to house the blade main body 30 in accordance with the angle of the hinge connection or to protrude the blade main body 30 to the outside through the blade protrusion groove 410.

The hinge member 50 is a means for hinging the main body case 10 and the safety case 40 together.

Examples of specific shapes of the safety case 40 and the hinge member 50 will be described later with reference to FIGS. 3 and 4 additionally.

The stopper 60 prevents the detachment of the blade main body portion 30 and the guide member 20 from each other. When the user desires to replace the blade body 30, the new blade body 30 is coupled to the guide member 20 after the stopper 60 is separated from the body case 10, The blade main body 30 can be replaced.

3 is a cross-sectional view for explaining a state in which the blade main body 30 is housed in the safety case 40 in one embodiment of the present invention. FIG. 4 is a cross- Sectional view for explaining a state in which the blade main body portion 30 protrudes outward through a blade protrusion groove 410 formed in the safety case 40. [

3 and 4, the hinge member 50 may be configured to include a fixing pin 510 and an elastic member 520.

The fixing pin 510 is inserted into a first coupling hole (not shown) formed in the main body case 10 and a second coupling hole (not shown) formed in the safety case 40, (10).

The fixing pin 510 may be positioned at the lower end of the safety case 40 and the lower end of the main body case 10 and may be disposed between the safety case 40 and the upper end of the main body case 10, A clearance (D) is formed to limit the angle of rotation. The clearance D restricts the degree of protrusion of the blade main body 30 to the outside by limiting the rotation angle of the safety case 40.

The elastic member 520 provides an elastic force to the safety case 40 in a direction in which the blade main body 30 is accommodated in the safety case 40 to rotate the safety case 40 to the main body case 10 at a predetermined angle Thereby performing a hinge coupling function. For example, the elastic member 520 may be a torsion spring.

Hereinafter, the specific use state of the cutter blade with enhanced safety according to an embodiment of the present invention will be described as a storage mode in which the blade main body 30 is not used and a use mode in which the blade main body 30 is used .

5 is a view showing a state in which the blade main body 30 is housed in the safety case 40 in a storage mode in which the blade main body 30 is not used.

5, in the storage mode in which the blade main body 30 is not used, the safety case 40 is urged in the longitudinal direction of the main body case 10 by the elastic force provided by the torsion spring which is the elastic member 520 The blade main body 30 is housed in the safety case 40 without protruding out of the safety case 40. [

6 is a view illustrating a state in which the blade main body 30 protrudes outward through a blade protrusion groove 410 formed in the safety case 40 in a use mode using the blade main body 30. [

6, in the use mode using the blade main body 30, the safety case 40 is rotated around the center axis of the fixing pin 510 by an external force exerted by the user, (30) protrudes through a blade protrusion groove (410) formed in the safety case (40).

As described in detail above, according to the present invention, the blade main body can be securely housed in a state in which the cutter knife is not used, and even when the cutter knife is used, So that it is possible to provide a cutter knife which greatly enhances safety in use.

In addition, there is an effect that a cutter knife capable of improving convenience in use is provided by allowing the blade main body to be used only by an operation of bringing the cutter knife into contact with a target object such as paper.

Further, when the user finishes using the cutter knife, there is an effect that the cutter knife can be provided that can automatically store the blade main body into the safety case by rotating the safety case using the elasticity of the torsion spring.

In addition, there is an effect that a cutter knife capable of ensuring the safety of children and juveniles who are not conscious of safety is provided.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. Further, it is obvious that various modifications and variations can be made without departing from the scope of technical idea of the present invention by anyone having ordinary skill in the art.
