Description

Technical Field

[0001] This invention relates to a writing instrument with a safety device that achieves the core-dropping action by shaking, and more specifically, to a writing instrument with a safety device that achieves the core-dropping action by shaking, wherein the safety device restricts the action to prevent the core-dropping component, which has a predetermined load due to impact during movement, from falling due to external vibration. Background Technology

[0002] Generally, in writing instruments that perform the core-feeding action, the core-feeding rod extends to the upper part of the pen body, and the pen lead is extended and retracted by pressing the core-feeding rod.

[0003] This existing writing instrument with a core-feeding action has the inconvenience of requiring the user to change the position of their fingers holding the pen and move their thumb to the core-feeding rod in order to perform the core-feeding action.

[0004] Therefore, a writing instrument was developed that, while holding the pen body, can perform the core-feeding action by shaking the writing instrument without changing the position of the fingers.

[0005] Existing writing instruments that use a load body, i.e., writing instruments that perform the core-feeding action by shaking the writing instrument, have a core-feeding actuation member formed inside the pen body, which is attached to the outer surface of the core-feeding actuation member, and the core-feeding action is performed by applying a load to the core-feeding actuation member.

[0006] However, while existing writing instruments using a load-bearing body improve the convenience of the refill action, when subjected to vibration while stored in a bag or similar container without being used, the load-bearing body presses down on the refill action, causing the protruding refill to contaminate the bag or similar items.

[0009] Korean Utility Model Registration No. 20-0308080 Summary of the Invention

[0010] Therefore, the object of the present invention is to provide a writing instrument with a safety device that achieves the core-dropping action by shaking, by having a stop to restrict the movement of the core-dropping action member formed in the pen body, thereby preventing the core-dropping action due to vibration when the writing instrument is stored and not in use.

[0011] The present invention includes: a pen body; a telescopic cap coupled to the lower part of the pen body; a core actuating member formed inside the pen body; a core gear formed on the upper part of the core actuating member; a pen clip coupled to the upper part of the pen body to prevent the core actuating member inserted inside from disengaging; and a stop block on the upper side of the pen body to restrict the movement of the core actuating member between it and the pen clip constituting the pen clip.

[0012] Furthermore, the present invention provides a writing instrument with a safety device that achieves the core-falling action by shaking, comprising:

[0013] The pen body has a marking groove formed on the upper part, which is used to fasten the pen clip to the correct position. A pen body lifting hole is formed on the lower part of the marking groove to guide the lifting of the stop. The pen body is formed such that the diameter of the lower part is smaller than the diameter of the upper part so as to couple the rubber retainer. A stepped surface is formed on the inner side to contact the lower part of the core gear. A rubber retainer and a telescopic cap are coupled on the lower outer side.

[0014] A refill actuating member, inserted into the pen body, is formed of a load body having a predetermined load and is a tube with an open lower portion to allow insertion of the pen refill. The refill actuating member includes: a refill rod extending upwards from the upper side of the pen clip; a locking protrusion formed on the lower side of the refill rod with a diameter larger than that of the refill rod; a rotating protrusion formed at a predetermined interval from the locking protrusion; and a locking protrusion formed at a predetermined interval below the rotating protrusion.

[0015] The pen clip consists of a pen clip body and a pen clip plate. The pen clip body is attached to the upper part of the pen body to prevent the internal structure from disengaging and is formed into a tube to limit the movement of the stop block due to vibration. The pen clip plate protrudes to one side.

[0016] The pen clip body has a pen clip lifting hole, which allows the stop protrusion of the insertion block to move up and down. A disengagement protrusion protruding towards the pen clip lifting hole is formed on the lower inner side of the pen clip piece to prevent the stop block from disengaging. An anti-disengagement protrusion is formed at predetermined intervals above the anti-disengagement protrusion to prevent the stop block from being released from its locked state.

[0017] A stop is included between the pen clip body and the pen clip plate. The stop includes: a stop body, which is formed into a curved surface like the shape of a pen body; a grip protrusion that protrudes from both sides of the stop body and protrudes from the outside of the pen clip plate, so that it can be gripped by hand; and a stop protrusion that passes through the pen body lifting hole and the pen clip lifting hole on one side of the pen body and is inserted into the interior of the pen body.

[0018] Preferably, a space is formed between the locking protrusion and the rotating protrusion, and a stop protrusion of the block is inserted into the space to allow it to move up and down.

[0019] Preferably, the rotational induction gear is divided into teeth, and when coupled with the core-operating component, in order to allow the locking protrusion to enter the lower side of the locking gear, the opposing tooth portions on both sides form an insertion groove that penetrates towards the locking gear side.

[0020] Preferably, the anti-detachment protrusion and the fixing protrusion are formed as arc-shaped or triangular inclined surfaces, so that when coupled with the stop block and raised and lowered, the pen clip can be lifted and moved outward.

[0021] Preferably, the gripping protrusion is formed as a curved surface composed of valleys and hills to prevent slippage.

[0022] Invention Effects

[0023] The present invention has a stop block at the upper part of the pen body between the pen body and the pen clip. The stop block restricts the lifting and lowering movement of the pen core dropping mechanism, thereby preventing the pen core from dropping due to shaking when stored in a bag or similar object, and preventing the bag or similar object from being contaminated.

[0024] Furthermore, even when neither the core-feeding mechanism nor the core-feeding gear is fixed inside the pen body to prevent vertical lifting or rotation, the core-feeding action is still performed by vertical lifting. Moreover, since no protrusions or grooves are formed inside the pen body to prevent the core-feeding mechanism or core-feeding gear from rotating, assembly is not only easy, but productivity is also improved.

[0034] The following is a detailed description with reference to the accompanying drawings.

[0035] The present invention includes: a pen body 10; a telescopic cap 20 coupled to the lower part of the pen body 10; a core actuating member 30 formed inside the pen body 10; a core gear portion 40 formed on the upper side of the core actuating member 30; a pen clip portion 50 coupled to the upper part of the pen body 10 to prevent the core actuating member 30 inserted inside from disengaging; and a stop block 60 on the upper end side of the pen body 10 to restrict the movement of the core actuating member 30 between it and the pen clip piece 52 constituting the pen clip portion 50.

[0036] The pen body 10 has a marking groove 11 formed on the upper part for coupling the pen clip 50 to the correct position, and a pen body lifting hole 12 formed on the lower part of the marking groove 11 for guiding the lifting and lowering of the stop block 60.

[0037] The pen body 10 is formed such that the diameter of its lower part is smaller than the diameter of its upper part so as to couple the rubber retainer 13, and a stepped surface 14 is formed on the inner side of the pen body to contact the lower part of the drop core gear 40.

[0038] The lower outer side of the pen body 10 is provided with a rubber retainer 13 for anti-slip purposes.

[0039] A telescopic cap coupling portion 15 is formed at the lower part of the pen body 10.

[0040] The telescopic cap 20 is coupled to the lower telescopic cap coupling part 15 of the pen body 10 and has a telescopic hole for the pen refill 1 to extend and retract.

[0041] The core-feeding actuating member 30 is formed by a load body having a predetermined load, and is formed as a tube with an open lower part, so that the pen refill 1 can be inserted.

[0042] The upper end of the dropper actuation member 30 is formed by a dropper rod 31 extending to the upper side of the pen clip 50.

[0043] A locking protrusion 32 with a diameter larger than that of the core rod 31 is formed on the lower side of the core rod 31 of the core actuating member 30, and a rotating protrusion 33 is formed at a predetermined interval from the locking protrusion 32, and a locking protrusion 34 is formed at a predetermined interval on the lower side of the rotating protrusion 33.

[0044] The locking protrusion 32 is composed of a pen clip locking surface 32a that contacts the upper inner side of the pen clip body 51 and a stop locking surface 32b that contacts the stop protrusion 63.

[0045] The rotating protrusion 33 is formed in four equally spaced protrusions.

[0046] The locking protrusion 34 is formed in two on both sides, so that it can pass through the insertion groove 43 when coupled with the core gear part 40.

[0047] A space 35 is formed between the locking protrusion 32 and the rotating protrusion 33, and the stop protrusion 63 of the stop block 60 is inserted into the space.

[0048] The rotating protrusion 33 and the locking protrusion 34 have sharp ends to ensure smooth engagement with the rotating guide gear 41 and the locking gear 42.

[0049] The core gear part 40 is formed as a tube, inserted from the lower part of the core actuating member 30, and located at the lower part of the locking protrusion 32.

[0050] A coupling position confirmation groove 40a is formed on the upper part of the core gear section 40 so that when coupled with the core actuating member 30, the locking protrusion 34 can be inserted after confirming the position of the insertion groove 43.

[0051] The core gear section 40 is composed of a rotation-inducing gear 41 and a locking gear 42 that protrude from the inner side toward the center.

[0052] The rotary induction gear 41 is divided into 8 teeth. When coupled with the core-feeding member 30, in order to allow the locking protrusion 34 to enter the lower side of the locking gear 42, the opposing tooth portions on both sides form an insertion groove 43 that penetrates into the locking gear 42.

[0053] The locking gear 42 is divided into four teeth and forms a locking groove 42a for inserting the locking protrusion 34.

[0054] The rotation-inducing gear 41 and the locking gear 42 of the drop core gear are formed with inclined surfaces that are opposite to each other.

[0055] The pen clip 50 is attached to the upper part of the pen body 10 to prevent the internal structure from detaching, and a stop 60 is provided to control the movement caused by vibration.

[0056] The pen clip 50 includes: a pen clip body 51, which is formed as a tube so that the dropper rod 31 extends to the upper part; a pen clip piece 52 protruding on one side of the pen clip body 51; and an anti-slip surface 53 that contacts the upper surface of the dropper gear part 40.

[0057] A pen clip lifting hole 54 is formed on the side of the pen clip body 51 where the pen clip piece 52 is formed, so that the stop protrusion 63 of the insertion stop 60 can be raised or lowered.

[0058] An anti-disengagement protrusion 52a is formed on the lower inner side of the pen clip 52, protruding toward the pen clip lifting hole 54 to prevent the stop block 60 from disengaging. An anti-release protrusion 52b is formed at a predetermined interval from the upper side of the anti-disengagement protrusion 52a to prevent the stop block 60 from unlocking.

[0059] The pen clip lifting hole 54 is formed through the pen body lifting hole 12 at the same position.

[0060] The anti-detachment protrusion 52a and the fixing protrusion 52b can be formed as arc-shaped or triangular inclined surfaces, so that when coupled with the stop block 60 and raised and lowered, the pen clip 52 can be lifted and moved outward.

[0061] The stop block 60 includes: a stop block body 61, which is formed as a curved surface like the shape of the pen body 10; a grip protrusion 62, which protrudes on both sides of the stop block body 61 and is exposed on the outside of the pen clip 52, and can be gripped by hand; and a stop protrusion 63, which passes through the pen body lifting hole 12 and the pen clip lifting hole 54 on one side of the pen body 10 and is inserted into the interior of the pen body 10.

[0062] The gripping protrusion 62 can be formed as a curved surface composed of mountains and valleys to prevent slippage.

[0063] The operation process of the present invention will be described below.

[0064] The present invention includes: a pen body 10; a telescopic cap 20 coupled to the lower part of the pen body 10; a core-feeding actuating member 30 formed inside the pen body 10; a core-feeding gear portion 40 formed on the upper side of the core-feeding actuating member 30; a pen clip portion 50 coupled to the upper part of the pen body 10 to prevent the core-feeding actuating member 30 inserted inside from disengaging; and a stop block 60 on the upper end side of the pen body 10 to restrict the movement of the core-feeding actuating member 30 between it and the pen clip forming the pen clip portion 50. Thus, when the pen core 1 is retracted, the stop block 60 moves upward to restrict the core-feeding actuating member 30 from descending. Thus, when the pen is not in use, the stop block 60 controls the movement of the core-feeding actuating member 30 by shaking, thereby preventing the pen core 1 from extending.

[0065] In addition, in order to use the writing instrument, when the grip protrusion 62 of the stop block 60 is held and the writing instrument is moved downward, the stop protrusion 63 moves to the lower side of the pen clip lifting hole 54 and the pen body lifting hole 12, releasing the locking state that is in contact with the stop locking surface 32b of the core-feeding member 30.

[0066] That is, the stop protrusion 63 of the stop block 60 rises and falls between the space 35 formed between the locking protrusion 32 and the rotating protrusion 33, thereby restricting the rise and fall of the core-feature actuating member 30 when it contacts the stop block locking surface 32b of the locking protrusion 32, and allowing the core-feature actuating member 30 to rise and fall when it moves to the lower side of the locking protrusion 32.

[0067] Thus, when the moving stop 60 releases the locking state of the core-feeding actuating member 30, if the user shakes the pen body 10, the core-feeding actuating member 30 will descend, and the rotating protrusion 33 of the core-feeding actuating member 30 will contact the rotation-inducing gear 41 of the core-feeding gear part 40, causing the core-feeding gear part 40 to rotate by a predetermined angle. At the same time, the locking protrusion 34 of the core-feeding actuating member 30, which is supported by the spring elasticity, will contact the locking gear 42, causing the core-feeding gear part 40 to rotate and be locked into the locking groove 42a. The core-feeding actuating member 30 will be locked into the locking groove 42a after descending a predetermined interval, thereby performing the extension action of the pen refill 1 extending from the telescopic cap 20.

[0068] Furthermore, when the pen body 10 is shaken again, the core-dropping actuating member 30 descends, the locking protrusion 34 disengages from the locking groove 42a, and at the same time, the rotating protrusion 33 contacts the rotation induction gear 41, causing the rotating gear part 40 to rotate. With the locking protrusion 34 of the core-dropping actuating member 30, which rises again through elasticity, located in the space between the locking gears 42, the core-dropping actuating member 30 rises and performs the retraction action of the pen core 1, which is elastically supported by the spring.

[0069] In addition, when the rotating protrusion 33 of the core-feeding member 30 contacts the rotation-inducing gear 41, the lower side of the core-feeding gear part 40 contacts the stepped surface 14 of the pen body 10 and rotates. When the locking protrusion 34 contacts the locking gear 42, the upper part of the rotating gear contacts the lower part of the anti-slip surface 53 of the pen clip body 51 and rotates.

[0070] In addition, the upper part of the core-feeding member 30 has a core-feeding rod 31 extending to the upper side of the pen clip 50, so that the core-feeding action of the writing instrument can be performed by shaking or pressing the core-feeding rod 31 according to the user's needs.

[0071] Furthermore, when the core-feeding actuating member 30 is coupled to the core-feeding gear 40, the coupling position confirmation groove 40a and the insertion groove 43 are aligned, and the locking protrusion 34 is aligned with the coupling position confirmation groove 40a before coupling, thereby easily coupling the core-feeding gear 40 to the core-feeding actuating member 30.

[0072] In addition, by forming an insertion groove 43 through the opposite two sides of the tooth portion of the rotation guide gear 41 to the side of the locking gear 42, the locking protrusion 43 can be inserted into the lower side of the locking gear 42.

[0073] In addition, when the stop block 60 rises and falls to restrict or release the movement of the core-feeding member 30, it passes through the fixing protrusion 52b protruding from the upper part of the pen clip 52. However, due to the elasticity of the pen clip 52, the pen clip 52 opens outward to move the stop block 60.

[0074] In addition, the stop 60 forms the stop body 61 as a curved surface, such as the outer curved surface of the pen body 10, and is adjacent to the pen body 10, thereby minimizing the protrusion of the grip protrusion 62 for gripping the stop 60 outward to the pen clip 52.
