Description
Technical Field
The present invention relates to a writing tool in which a pen core is extended and contracted by a knock button provided at a side surface, and more particularly, to a writing tool in which a pen core is extended and contracted by a knock button provided at a side surface of a pen body, and the knock button is operated in one direction to facilitate the operation of the knock for extending and contracting the pen core, thereby improving the convenience of use, and the knock button is operated in only one direction to facilitate the operation of the pen core for extending and contracting the pen core, thereby accurately performing the knock operation.
Background
In general, a writing instrument of the knock type is configured such that a writing lead elastically supported by a spring is extended and contracted from a writing lead holder inside a pen body in response to a user's pressing.
The core-drop type writing instrument is classified into the following writing instruments according to the core-drop action: a writing tool which is coupled to the upper part of the pen body and completes the pressing action on the upper part and the releasing action on the side surface, and a writing tool which performs the extension and contraction of the pen core and the pen point by repeatedly performing the pressing action on the upper part.
However, the conventional knock-type writing instrument has a problem that it is inconvenient to change a state of holding the pen for the telescopic operation.
In order to solve the above-described problems, writing instruments have been developed in which the extension and retraction of the writing core is operated on the side surface of the pen body without changing the state of holding the writing instrument.
In a conventional writing instrument, a guide groove is formed in a side surface of a pen body, and an operating member which moves up and down along the guide groove and in which a pen core is provided is formed, and the operating member is configured by a knock button exposed to an outer side of the pen body.
Further, a plurality of locking protrusions are formed in the guide groove of the pen body, and a locking protrusion to be locked to the locking protrusion is formed in the actuator, so that the pen core is completely protruded or retracted depending on whether the locking protrusion is located in one of the plurality of locking protrusions.
On the other hand, when the knock button formed on the outer side of the actuator is pressed in order to extend or retract the writing instrument, the locking protrusion is disengaged from the locking protrusion and is moved in the vertical direction of the guide groove, and then the knock button is moved in the vertical direction, thereby completing the extension or retraction of the writing lead.
However, the operation of moving the knock button in the up-down direction is an operation of moving the knock button in the up-down direction while keeping the locking protrusion disengaged from the locking protrusion, and the operation of moving the knock button in the up-down direction or the down direction while keeping the direction of the force applied to the knock button in order to extend and retract the pen core in the inward-pressed state has a problem that the extending and retracting operation is difficult.

When the knock actuator 30 is coupled to the pen body 10, the knock button 32 protruding outward can be depressed inward by the elastic surface 35, and thus can be easily inserted and coupled.
The expansion control unit coupling part 33 is formed with an engaging protrusion 33a having an open upper end protruding inward at a predetermined interval, thereby preventing the elevation operation member 42 constituting the inserted expansion control unit from being separated to the upper side.

The lower end of the telescopic operation protrusion 41b and the upper end of the rotation guide protrusion 41c are formed as inclined surfaces in opposite directions, and are rotated in one direction while contacting the upper and lower ends of the fixing protrusion 42a formed at the elevation operation member 42.
The lifting/lowering actuator 42 is formed as a pipe body so as to be rotatably inserted into the rotary actuator 41, and fixed protrusions 42a are formed on both sides of an upper portion of an inner side of the lifting/lowering actuator 42, and both outer side surfaces of the lifting/lowering actuator 42 are formed as flat coupling surfaces 42b, and protruding insertion protrusions 42c are formed on both surfaces between the coupling surfaces 42 b.
A fixing groove 42d is formed on the upper inclined surface of the fixing protrusion 42a to lock the lower corner of the expansion/contraction operation protrusion 41 b.
The upper end and the lower end of the fixing projection 42a are formed with inclined surfaces facing in opposite directions, the upper end inclined surface is formed to be in surface contact with the lower end inclined surface of the expansion/contraction operation projection 41b, and the lower end inclined surface is formed to be in surface contact with the upper end inclined surface of the rotation guide projection 41 c.
As shown in the other embodiment of fig. 12, the present invention may be implemented such that the rotation operating member 41 is fixedly installed at the upper end of the pen body 10 to prevent rotation, and the lifting operating member 42 coupled to the extension control unit coupling part 33 is coupled to be lifted and lowered to complete the rotation operation.
The operation of the present invention will be described below.
As described above, when the present invention including the pen body 10, the knock actuator 30 inserted into the pen body 10, and the expansion control unit coupled to the upper end of the knock actuator 30 to control the expansion and contraction of the pen point of the pen core 1 is applied, the pen core 1 is expanded or contracted while the knock actuator 30 configured to be operable on the side surface of the pen body 10 is repeatedly lowered in a state where the pen body 10 is held.
More specifically, in the present invention, when the pen point of the pen refill 1 needs to be protruded, the knock button 32 of the knock actuator 30 is operated to be lowered, and at this time, the lift actuator 42 constituting the telescopic control means is lowered together with the knock button 32, and the fixing protrusion 42a formed inside is brought into contact with the locking rotation guide protrusion 41c-1 of the rotation protrusion 41c of the rotation actuator 41 to be lowered, and the locking rotation guide protrusion 41c-1 is pushed to one side to rotate the rotation actuator 41 by a predetermined angle, so that the lowered fixing protrusion 42a moves to the space D where the locking rotation protrusion 41b can be locked, and the pen point of the pen refill 1 is lowered together to be protruded.
Then, when the knock button 32 of the descending knock actuator 30 is released, the knock actuator 30 ascends due to the elasticity of the spring S, and the ascending/descending actuator 42 coupled to the expansion control unit coupling part 33 ascends together.
When the vertically movable operation member 42 is lifted, the upper end inclined surface of the fixed protrusion 42a and the lower end inclined surface of the telescopic operation protrusion 41b are lifted in contact with each other, and at this time, the telescopic operation protrusion 41b is pushed open to rotate the operation member 41 by a predetermined angle, and the lower end corner portion of the telescopic operation protrusion 41b is inserted into the fixed groove 42d of the vertically movable operation member 42 fixed to the lifting operation member being lifted, so that the lifting operation member is not further lifted, and the pen tip of the pen core 1 protruded is not retracted.
On the other hand, the fixing groove 42d formed at the upper end of the fixing protrusion 42a is located at a position not passing through the corner of the expansion/contraction operation protrusion 41b by the difference of the degree of the distance a between the expansion/contraction operation protrusion 41b and the rotation guide protrusion 41c-2, so that the corner of the expansion/contraction operation protrusion 41b is inserted into the fixing groove 42d of the ascending/descending operation member 42, and the ascending is not continued in a state where the pen core 1 is protruded, and the pen core 1 can maintain the protruded state.
In addition, when the present invention is used, if it is necessary to retract the pen tip of the protruding pen core 1, the knock button 32 of the knock actuator 30 is lowered again, and at this time, the lower end inclined surface of the fixing protrusion 42a formed in the lift actuator 42 comes into contact with the upper inclined surface of the release rotation guide protrusion 41c-2 of the rotation protrusions 41c to complete the lowering, and at this time, the lowered fixing protrusion 42a pushes the release rotation guide protrusion 41c-2 open and the rotation actuator 41 rotates, so that the fixing protrusion 42a is positioned in the space E between the release rotation guide protrusion 41c-1 and the release rotation guide protrusion 41c-2, which can retract the protruding pen core 1.
When the knock button 32 of the knock actuator 30 is released in the above state, the knock actuator 30 is lifted by the repulsive force of the spring S, and the lift actuator 42 coupled to the expansion control unit coupling portion 33 of the knock actuator 30 is lifted, and the upper inclined surface of the fixing protrusion 42a of the lift actuator 42 is brought into contact with the lower inclined surface of the expansion operation protrusion 41b to complete the lifting, so that the rotating actuator 41 is rotated by the lifting force of the expansion operation protrusion 41b, and the fixing protrusion 42a is positioned between the two expansion operation protrusions 41b, whereby the pen point of the pen cartridge 1 is completely retracted.
At this time, when the fixing groove 42d of the fixing protrusion 42a, which is lowered between the rotation guide protrusions 41c, is raised, it is separated from the corner portion of the expansion/contraction operation protrusion 41b and positioned on the inclined surface, thereby completing the raising operation.
Further, the distance B between the telescopic operation protrusion 41B and the rotation release guide protrusion 41C-2 is formed to be narrower than the length C of the fixing protrusion 42a, so that even if the fixing protrusion 42a is shaken by an external impact or the like when it is lowered toward the space D for the extension and retraction of the pen core 1, the fixing protrusion 42a is longer than the distance B and the lower end is locked to the rotation release guide protrusion 41C-2, and is stably lowered to the space D and then raised to the telescopic operation protrusion 41B, so that the protruding pen core 1 can be maintained in a protruding state, and the locking operation can be completed.
On the other hand, the falling core operation rotation preventing surface 10a formed on the inner surface of the pen body 10 is in surface contact with the rotation preventing surface 36 of the falling core operation member 30 inserted into the pen body 10, so that the falling core operation member 30 is lifted and lowered without shaking left and right, the coupling surface 42b of the lifting operation member 42 inserted into the telescopic control unit coupling portion 33 is in surface contact with the insertion guide surface 33b, and the lifting operation member 42 is lifted and lowered without shaking left and right, so that the rotation operation member 41 inserted into and coupled to the lifting operation member 42 is rotated to complete the telescopic operation.
In another embodiment of the present invention, as shown in fig. 12, when the rotational actuator 41 is fixedly installed at the upper end of the pen body 10 and the elevation actuator 42 coupled to the extension/contraction control unit coupling portion 33 is coupled to be elevated and rotated inside the extension/contraction control unit coupling portion 33, the fixed protrusion 42a formed on the inner wall surface of the elevation actuator 42 is elevated and rotated in one direction by a predetermined angle by the extension/contraction operation protrusion 41b and the rotation guide protrusion 41c formed on the outer wall surface of the rotational actuator 41.
