Description

{SCISSORS HAVING BLADES TO USE SELECTIVELY}

The present invention relates to scissors, and more particularly, to a scissors capable of performing a dual function as a knife and scissors, and capable of selectively using a blade having excellent safety.

Knife and scissors are commonly used as cutting devices for personal and portable purposes.

The scissors are cutting devices in which two bodies are connected to each other by mutual hinges, and the blade portions are opposed to each other and the two knobs are spaced from or adjacent to the hinge so that the pair of blade portions are in close contact with each other, As shown in Fig.

FIG. 1 discloses such a general type of scissors. In the case of scissors having a general structure, two blades having one end coupled with a handle are opposed to each other with a hinge piece, the contact surfaces of both blades are in contact with each other, So that the cutting object can be cut.

However, in the case of such a scissors, since it performs only one operation, it is often required to be used in parallel with the sword, and there is an inconvenience in using the scissors according to the size because scissors have different functions according to their sizes.

In recent years, a blade capable of separating blades or capable of being used in parallel with a knife has appeared in order to solve this problem. Registration Utility Model No. 20-0381162 discloses such a knife-combination scissors.

Fig. 2 is an exploded view of the scissors of this publication.

Specifically, the knob 20a of the blade portion comprises a protruding piece 22a for forming a gripping groove 21a and a pressing piece 23a for pressing upon scissors so as to insert a thumb. The handle 10a of the scissors portion is formed with a grip portion 11a on its bottom surface so as to be able to hold the fingers except for the thumb and has a pressing piece receiving groove 12a Is formed.

Thus, the interference between the pressing piece 23a to be used as a scissors and the handle 10a of the scissors portion is reduced, that is, the frictional force is reduced, so that the scissors can be easily scissored. When the knife is used as a knife, the pressing piece 23a is flush with the knob 10a of the scissors so that the knob of the knife can be integrally formed.

In this way, the scissors separating the blade and the blade have the advantage of being able to flexibly adapt to various environments because the use of a knife can be used, which has a problem in durability because the hinge portion is repeatedly separated.

In the case of the general scissors shown in Fig. 1, as the use is repeated, the blade's adhesion is gradually weakened, so that the function as scissors is deteriorated or the function is seriously lost. In the case of the improved blade of Fig. 2, .

In addition, the structure for repetitive desorption is complicated, and there is a possibility of physical damage due to blade separation.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a scissors capable of selectively using scissors and knives while being structurally stable and capable of selectively using dies that are durable.

The first blade portion and the second blade portion function to cut the object to be cut which is interposed therebetween repeatedly in close contact or spacing in some or all of the same manner as general scissors, and these blades may be linear, curved, wavy, serrated And the like.

The first handle portion and the second handle portion may be connected to the first and second blade portions, respectively, and may have various forms capable of being grasped by hand. The description of the present invention and the drawings are not intended to limit the scope of the present invention Do not.

The user repeatedly separates the first and second grips from the first body and the second body while holding the first and second grips with one or both hands. In the description of the present invention, 2 bodies are in close contact with each other so that the first and second blade portions are not completely exposed to the upper side or the lower side, more precisely, the first blade portion is disposed along the surface of the second body, And a state in which the first and second blade portions are spaced apart from each other by a predetermined angle are defined as the use state of the scissors.

In the concept of the present invention, a state in which the blade is rotated in the opposite direction to the use state is defined as a blade use state, and will be described later.

The direction in which the handle extends from the handle to the body is referred to as both sides and the position or direction in which the second handle is disposed with respect to the first handle is referred to as the upper side or the height direction as in the illustrated embodiments. In addition, the position of the first body is defined as the forward position and the position of the second body is defined as the rearward position in the state where the first body and the second body overlap each other. It should be noted, however, that this directionality can be explained differently depending on the arrangement state of the scissors.

3 is a plan view of a scissors that can be selectively used with a blade according to a first embodiment of the present invention.

As described above, the first blade 110 of the first body 100 is formed in a tip shape and has a blade part 120 leading to the upper side. In a state of using a blade to be described later, ) To function as a blade.

In the present invention, the first end 130 of the first body 100 has a sharp-pointed shape, and the second end 230 of the second body 200 maintains the obtuse state. Here, the storage state means that the first end 130 is not exposed in the longitudinal direction. In this case, it is possible to prevent damage to the body or damage to the body by the sharp first end 130 in the storage state.

Accordingly, the second end portion 230 may be formed in a blunt shape, and may be formed in a rounded shape, and the second end portion 230 may be longer in one side than the first end portion 130 in the storage state .

The blade portion 120 is formed substantially in the opposite direction to the first blade portion 110 and extends upward from the first end portion 130 to the back portion of the first body 100 so as to function as a blade. The blade 120 is formed on the end of the first body 100 and has a predetermined inclination with respect to the first blade 110 as shown in FIG. According to this concept, the first body part 100 is formed such that the first blade part 110 of the bottom part extends from the other side where the hinge part 300 is disposed and the blade part 120 extends upwardly from the first end part 130 Are formed. The blade portion 120 may have a length shorter than that of the first blade portion 110 to prevent exposure in an undesirable storage state.

In this state, the first body 100 is rotated upward, the second body 200 is rotated downward, and the second body 200 is separated from the upper body and the lower body and is in close contact with the front and rear sides, As shown in Fig.

The first end 130 and the second end 230 are spaced apart from each other in a state where the first body 100 is rotated downward and the second body 200 is rotated upward, Which means that the blade 120 can be operated in the space.

The first handle 410 connected to the first body 100 is disposed below the second handle 420 connected to the second body 200 in the form of a scissors, And to change the usage status.

To this end, it is preferable that the handle portion is provided with a stopper structure that can prevent the knob portion from being inadvertently switched from the stored state to the blade used state.

In the first embodiment of the present invention, as the stopper, a first stopper part 411 provided in the first handle part 410, a second stopper part 421 provided in the second handle part 420, And a configuration capable of being elastically deformed in a part of the section is proposed.

3, the first handle 410 is disposed in front of the second handle 420, and the first stopper 411 protruding upward from the first handle 410 is disposed on the second handle 420, And is engaged with the second stopper portion 421 protruded to the lower side of the portion 420 to function to prevent further rotation in the stored state.

Fig. 4 is a plan view for explaining a case in which the scissors capable of selectively using the blade of Fig. 3 are operated in a state of using the blade. Fig.

The first handle 410 and the first body 100 are disposed at the front side while the second handle 420 and the second body 200 are disposed at the rear side in the storage state and the scissors use state, Only the upward and downward rotational movements are made centering on the branch 300.

However, as described above, when the first stopper portion 411 and the second stopper portion 421 hold the scissors in a used state, the rotation of the first and second blade portions 110 and 210 is limited , And additional operation is required to switch to the blade state.

However, in this case, it is preferable that the first blade portion 110, which is formed in an advanced shape, is moved to the outside It is preferable to perform a predetermined additional operation when switching from the storage state to the blade use state because there is a possibility of damage to the body,

The first handle 410 and the second handle 420 may be substantially in the shape of plates facing each other in the front and rear directions. In order to restrict the rotation of the stopper unit, the first stopper unit 411, And the second stopper portion 421 may have protrusions or steps so as to be engaged in the front and rear directions.

When the first stopper portion 411 and the second stopper portion 421 are in confrontation with each other, the rotation is further restricted. In the first embodiment of the present invention, the first handle 410 or the second handle 421, The portion 420 is elastically deformed in the forward and backward directions so that the grip portion can be cross-moved.

Specifically, at least one of the first handle 410 or the second handle 420 has a deformable portion 412 that can be elastically deformed in forward and backward directions, and the first stopper 412, The front and rear positions of the first stopper portion 411 and the rear stopper portion 421 are switched so that the first stopper portion 411 is positioned rearward and the second stopper portion 421 is positioned forward, 410 and the second handle 420 can be rotated more tightly.

The first end portion 130 is exposed downwardly of the second end portion 230 and the blade portion 120 is spaced apart from the bottom portion of the second blade portion 210 to face each other.

At this time, the first end 130 can perform a prying action at the tip end portion, and when the object is placed on the knife edge portion 120, the first end portion 130 can be cut by the action of pushing the object at the cut portion of the object. At this time, since the sharp edges of the blade 120 and the blade 120 intersect with each other, the function as the blade can be further improved.

The first stopper portion 411 and the second stopper portion 421 are fixed to each other so as to be meshed with each other, and the blade portion 120 and the second blade portion 421 are engaged with each other, Which means that the angle and position of the body 210 can be fixed and used. When the second grip portion 420 is further moved forward or the first grip portion 410 is further moved rearward to release the fixed state, the first grip portion 410 is moved backward by the elastic restoring force, 2 can be switched to the storage state and the scissors use state by moving to the front of the handle portion 420. [

At least one of the first handle 410, the second handle 420, the first body 100, or the second body 200 may have elastic deformation and restoring force for forming the deformed portion 412 It is preferable that the deformable part 412 is formed of a superior material. In some cases, the deformable part 412 may be connected to a separate member or may be formed to have a thin thickness compared to other parts.

On the other hand, in the case of the above-mentioned concept of elastic deformation, there is a possibility of permanent deformation because repetitive deformation is performed forward and backward, and there is a possibility of a problem of clearance in the use state of the scissors. In consideration of this, a separate adjusting member may be alternatively or additionally attached to the concept of elastic deformation between the first handle 410 and the second handle 420. The adjusting member may be in a first state such that the handle can be in contact with only the storage state, and can function to turn the handle further in the detached state or the deformed second state to switch to the blade use state.

5 is a plan view of a scissors that may optionally be used with a blade according to a second embodiment of the present invention.

In the second embodiment of the present invention, the concept that the elastic member 500 is further disposed for switching the use state of the scissors, the storage state, and the blade use state will be described. The description overlapping with the first embodiment will be omitted.

An elastic member 500 is interposed between the first handle 410 and the second handle 420 or between the first body 100 and the second body 200, It is possible to provide an elastic restoring force in a direction in which the portions are spaced apart.

At this time, the concept of the modification of the first embodiment and the configuration of the first stopper part 411 and the second stopper part 421 may be applied. However, for the sake of simplicity and durability, The stopper portion 411 and the second stopper portion 421 may be arranged to have a spaced distance l.

The time when the elastic restoring force of the elastic member 500 is provided is from the storage state. When the first grip portion 410 and the second grip portion 420 are about to be rotated more than the stored state, that is, By providing resistance, it serves to prevent undesirable switching to blade use.

At this time, the user closely contacts the knobs against the resilient restoring force of the elastic member 500, and when the first body 100 is moved to the lower side of the second body 200, the user is switched to the state of using the blade .

When the user exerts the compressive force, the elastic member 500 can be switched to the storage state again.

The elastic member 500 may be in the form of a bent leaf spring coupled to a predetermined receiving space between the first handle 410 and the second handle 420, Various elastic means capable of providing an elastic restoring force such as a block can be applied.

The gap l can be variously formed according to a spaced distance or angle between the second blade part 210 and the blade part 120. It should be noted that the first stopper portion 411 and the second stopper portion 421 are in close contact with each other in a state of using the blade, thereby preventing further rotation.

A holding member (not shown) for closely contacting the first and second knobs 410 and 420 may be further provided for holding the blade in use, A hook, a ring, or a ring that prevents the elastic member 500 from being worn by the elastic member 500.

Figs. 6 and 7 are plan views of scissors that can be selectively used with a blade according to a third embodiment of the present invention.

The second end portion 230 of the second body 200 is formed to have a somewhat blunt shape so as to prevent the blade portion 120 from being exposed to the outside in the storage state as in the above embodiments, It is possible to give a sense of aesthetics dangerously because it is smaller, and it is not possible to exclude the possibility of injuring the body if a strong force is actually applied.

In the third embodiment of the present invention, an additional structure capable of further improving safety is presented.

As described above, the first body 100 having the blade unit 120 can be switched between the use state of the scissors, the storage state, and the blade use state through the mutual rotation relationship with the second body 200. The description of the handle, the body, the blade, and the blade is omitted. For convenience of description, both sides of the first and second embodiments are shown inverted, but the definition of the directionality is applied in the same manner as in the embodiments of the present invention.

Here, the first body 100 may further include a protrusion 140 having a length longer than the tip of the blade 120 at least one side of the upper side where the blade 120 is formed.

The protrusion 140 functions as a safety bar, and functions to prevent the blade 120 from being inserted into a body or an object when the one side is pierced. Therefore, it is preferable that the protruding portion 140 is formed in a substantially rectangular shape, a cylindrical shape, or a shape in which the end portions are rounded.

One end of the first body 100 is formed with a projection 140 from the top side, a receiving portion 150 in the form of a groove formed in the lower side thereof, and a receiving portion 150 formed in a bottom portion of the receiving portion 150 according to the structure of the projection 140. [ And a first end 130 which is a lower end and an end of the blade 120.

FIG. 6 shows a storage state, in which the first end 130 of the tip shape is obscured by the second end 230. Accordingly, as in the above-described embodiments, the use of the blade 120 is limited by the second end 230, and the protrusion 140 functions as an additional safety protrusion on the upper side. The protrusions 140 and the second ends 230 are preferably formed at substantially the same position on one side, but are not limited thereto.

7 shows the state of use of the blade, and the first end 130 is exposed downward in a state in which the second end 230 is rotated to overlap with the protrusion 140. [ Accordingly, the blade unit 120 can perform a pricking and cutting function. In the above-described embodiments, the substantially triangular space having the same shape as the receiving part 150 is formed, and cutting is performed by forming a sharp edge at the intersection of the blade part 120 and the second body 200, Same as. The cutting may be performed at the intersection of the blade 120 and the second body 200 but the second body 200 may be further raised so that the inner edge of the receiving part 150 is exposed It might be. In consideration of this, the blade portion 120 preferably maintains a sharp shape to the bottom of the receiving portion 150 as well as the inner edge portion.

In the case of the third embodiment described above, since the blunt protrusion 140 and the second end 230 have a double safety structure in the storage state, the scissors do not have a pointed shape toward the one side as a whole, This has the advantage of improving safety and visually providing a sense of stability.

In the meantime, the structure and the elastic member of the stopper described above may be applied to any one or more of the embodiments, but it is also possible that the protrusion 140 and the second end 230 can prevent further rotation The latching member can be additionally arranged. As the latching member 430 is formed on the first handle 410 and the second handle 420 is lowered, the lower end of the latching member 430 is hooked on the latching member 430, thereby restricting the rotation of the latching member 430. The latching member 430 may be selectively and additionally disposed on the first handle 410 and / or the second handle 420.

The configurations according to the embodiments of the present invention described above may be added or substituted with each other and include the concept of the use state of the scissors, the storage state, and the blade use state through the basic blade part and the body and the blade parts of the present invention Various modified embodiments will be included in the scope of the present invention.

The scissors capable of selectively using the blade of the present invention described above are provided with a scissors and a knife at the same time or overcome the troublesome operation of separating and using the scissors blade and allow the user to arbitrarily switch the use state of the scissors, The convenience for cutting the object to be cut can be maximized.

In addition, it has a structure for protecting the end portion having an advanced shape, and at the same time has a structure capable of restricting the rotation according to each state, so that it is possible to prevent injury to the body or damage to the object, and safety is improved.
