Description

Writing stick

The present invention relates to a lighting stick, and more specifically, to a lighting stick that can increase a promotional effect by emitting artificial light to the outside of a housing through an exposed member, and for easily finding a writing instrument in a dark place.

In general, writing instruments are convenient to use during the day, but they have the disadvantage of being impossible to use in dark places without separate lighting.

To overcome these shortcomings, many light pens have been designed that emit light at the tip of the pen.

That is, in order to supply current to the light-emitting diode of the light pen, a battery with a length and thickness of approximately the same as a finger is built into the upper part of the pen. However, if such a battery is put inside the pen, the actual required length of the pen tip cannot help but be shorter due to the length of the battery.

In addition, a separate button-type switch for turning the power on/off is provided to be exposed on the outside of the housing, but assembling a separate switch and connecting a complex circuit not only significantly increases the production cost, but also causes frequent failures.

In addition, conventionally known light pens have a light-emitting part provided at the location of the pen tip to identify the current writing status when taking notes in a dark place.

Therefore, the front part where the pen tip is located becomes brighter, which has the simple effect of enabling the user to write while seeing their writing situation.

However, since conventional light pens only emit light around the pen tip, it is not possible to expect commercial value or promotional effects for purposes other than the effect of being able to write in the dark, such as a knock to operate the pen tip, or light emitting from a specific part of the clip or housing, for decorative purposes.

The advantages and features of the present invention and the methods for achieving them will become apparent with reference to the embodiments described in detail below together with the accompanying drawings.

However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and the present embodiments are provided only to make the disclosure of the present invention complete and to fully inform a person having ordinary skill in the art to which the present invention belongs of the scope of the invention, and the present invention is defined only by the scope of the claims.

Additionally, the terminology used herein is for the purpose of describing embodiments only and is not intended to limit the present invention.

In this specification, the singular includes the plural unless specifically stated otherwise in the phrase. As used in the specification, "comprises" and/or "comprising" do not exclude the presence or addition of other components other than the mentioned components.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in a commonly understood sense by a person of ordinary skill in the art to which the present invention belongs.

Hereinafter, in order to explain the present invention more specifically, embodiments according to the present invention will be described in more detail with reference to the attached drawings.

The present invention comprises a housing (100), an exposed member (110) accommodated inside the housing (100) and having a portion exposed to the outside of the housing (100) by an operation applied from the outside, a battery (500) accommodated inside the housing (100) and having two electrodes (+, -) formed at different positions, an LED element (600) accommodated inside the housing (100) and emitting light when two terminals (610) (620) are respectively brought into contact with the electrodes of the battery (500), and a light transmission means (800) provided with one side facing the LED element (600) and the other side facing the LED element (600) to transmit a light source of the LED element (600), wherein the light source of the LED element (600) transmitted through the light transmission means (800) is transmitted when a portion of the exposed member (110) is exposed to the outside of the housing (100). This is the configuration observed from the outside of the housing (100).

Here, the externally applied action can connect or disconnect the electrodes (+, -) of the battery (500) and the two terminals (610) (620) of the LED element (600).

For example, the present invention applies a sealing structure of an object emergence mechanism including a housing in which a contents cartridge having a guide projection is accommodated inside, a cam groove is provided at a tip end and a guide groove is provided inside, a sleeve that is fitted into the contents cartridge and has a cam projection integrally formed on the outside, a twist cam groove in which the cam projection is fitted and slides, a cam pin that protrudes to move under the guidance of the cam groove of the housing at a position misaligned from the twist cam groove, and arms that extend toward the tip end and have a shaft hole formed therein, a center pin that protrudes outwardly at a central position in a ball shape, and an eccentric pin that protrudes at an eccentric position at a distance from the center pin and is fitted into the shaft hole of the arm to open and close an access passage, thereby controlling the position of a passage hole when the operating tube rotates in a twist direction and moves forward or backward at the same time under the guidance of the cam groove (Application No. 10-2021-0136917). It may be implemented to connect or disconnect the electrodes (+, -) of the battery (500) and the two terminals (610) (620) of the LED element (600).

When manipulating the appearance state of the exposed member (110) in a lighting stick having such a configuration, when the knock cap (200) protruding from the top of the housing (100) is pressed, the rotating cam (300) and the exposed member (110) are lowered simultaneously, and while compressing the spring (400), the ball tip (111) of the exposed member (110) is exposed outside the end of the housing (100).

When the knock cap (200) that was pressed is released after the bolt tip (111) is exposed, the exposed member (110) and the rotary cam (300) rise together due to the repulsive force of the spring (400) that was extruded, and the rotary cam (300) rotates at a certain angle due to the cam structure and is caught on the end face of the projection-inducing groove (120) provided in the housing (100), so that the rise of the exposed member (110) stops, and the bolt tip (111) at the tip of the exposed member (110) is exposed outside the housing (100).

With the operation of the housing (100) and the knock cap (200) and the rotating cam (300) having this structure, the exposure member (110) and the ball tip (111) repeatedly move in and out according to the repeated pressing operation of the knock cap (200).

Typically, the housing (100) is made of synthetic resin and has a hollow cylinder shape, with the upper and lower bodies separated and connected by screws, or recently, the upper and lower bodies are molded as one piece.

Inside the housing (100), ink is stored and writing is performed through the ball tip (111), and each component, including an exposed member (110), a knock cap (200), a rotating cam (300), and a spring (400), is accommodated, and a clip (140) is also provided on the outside.

In addition, a projection-guiding groove (120) is provided on the upper inner side of the housing (100) to guide the knock cap (200) to rise and fall through the gear projection (210), and also to catch the rotating cam (300) by making contact with the projection-guiding groove (120) when it rises.

The above knock cap (200) is integrally provided with a gear projection (210) to enable straight lifting and lowering movement through a lifting and lowering guide groove (120) inside the housing (100).

In addition, the above-mentioned rotary cam (300) is positioned so as to be able to rise and fall and rotate between the exposed member (110) and the knock cap (200), and a guide protrusion (310) is formed so as to come into contact with the above-mentioned gear protrusion (210) and the emergence/exit guide groove (120).

And, a spring (400) is elastically installed between the end of the exposed member (110) and the nib case (130) which is connected to the end of the housing (100) and has a hole (131) through which the ball tip (111) emerges.

Due to the elasticity of this spring (400), the rotary cam (300) and the exposed member (110) maintain the upward force when no external force is applied. The knock cap (200), the rotary cam (300), and the retraction-inducing groove (120) are used to press the knock cap (200) in and the exposed member (110) and the ball tip (111) are exposed through the hole (131) of the nib case (130) each time the process of pressing the knock cap (200) is repeated. Since the process of repeating the forward and backward movement is the same as the configuration of a knock-type ballpoint pen that is already known, a more detailed description will be omitted.

The present invention has a feature in its structure that when the knock cap (200) is pressed to move the exposed member (110) of the knock-type ballpoint pen forward, light generated from an LED-Light-Emitting Diode-element (600) provided inside at a specific location can be emitted from the housing (100), the knock cap (200), or the surroundings of the ball tip (111).

That is, a battery (500) is stored inside the housing (100).

The battery (500) mainly used in the present invention has two electrodes, +/-, each provided at different locations, and for example, it is made of a diameter of approximately 3 mm, which is similar to the thickness of an exposed member (110) used in electronic fishing lures, and a cylindrical product with a length of 5 to 20 mm depending on the capacity is applied.

This battery (500) has a centrally protruding electrode that is mainly a - pole, and a cylindrical side portion that is made of an electrical conductor and has a + pole.

Accordingly, when both terminals (610)(620) of the LED element (600) are in contact with these two +/- electrodes, a specific color is emitted at a set brightness from the LED element (600) by power from the battery (500).

As is known, LEDs have a high efficiency in converting electrical energy into light energy, so the battery (500) has a very long lifespan.

Meanwhile, inside the housing (100), a return spring (700) for power short-circuiting is further installed, the elastic coefficient of which is set to be relatively lower than the elasticity of the spring (400) that is elastically installed at the tip of the exposed member (110).

Accordingly, in order to use the ballpoint pen of the present invention, when the knock cap (200) is pressed to expose the ball tip (111) to the outside of the nib case (130), the return spring (700) with lower elasticity than the elasticity of the spring (400) for maintaining the elasticity of the exposed member (110) is pressed, so that the two electrodes of the battery (500) and the two terminals (610) (620) of the LED element (600) can each come into electrical contact to emit light.

And, when the knock cap (200) is pressed to release the knock state in order to bring the ball tip (111) into the housing (100) or the nib case (130) after finishing the writing instrument, the spring (400) exerts elastic force to raise the exposed member (110) and the rotary cam (300), and at the same time, the return spring (700) separates the electrodes of the battery (500) and the terminals (610) (620) of the LED element (600), thereby turning off the light.

In this way, when the two electrodes of the battery (500) and the two terminals (610)(620) of the LED element (600) are electrically contacted and light is generated from the LED element (600), a light transmission means (800) is further included to transmit the light source to a specific location so that it can be observed from the outside of the pen.

More specifically, the light source of the LED element (600) transmitted through the light transmission means (800) is observed from the outside of the housing (100) when a portion of the exposed member (110) is exposed to the outside of the housing (100).

Here, one side of the light transmission means (800) is in direct or indirect contact with the LED element (600) and the other side is in direct or indirect contact with the cross section of the housing (100), so that the light source of the LED element (600) is transmitted to the housing (100) through the cross section.

In addition, one side of the light transmission means (800) may be implemented to be in direct or indirect contact with the LED element (600), and the light source of the LED element (600) transmitted through the outer surface of the light transmission means (800) may be transmitted to the housing (100).

Below, specific embodiments to which the present invention is applied are described in detail.

Figures 1 to 4 illustrate a first embodiment according to the present invention.

That is, the rotating cam (300) has a hollow space formed inside it, and the LED element (600) is installed in this space with the terminals (610) (620) facing downward.

In addition, a case (450) for accommodating a battery (500) is interposed between the above-mentioned rotating cam (300) and the exposed member (110), and a fitting projection (451) is integrally formed in the case (450) so as to be inserted and connected into the interior of the exposed member (110).

And, a return spring (700) is elastically installed between the case (450) and the rotating cam (300).

This return spring (700) is set to have lower elasticity than the spring (400) for elastically supporting the exposed member (110).

In this first embodiment, a passage (320) is formed to communicate with the space in the rotating cam (300) by the light transmission means (800), so that light generated from the LED element (600) can be transmitted to the knock cap (200) through the passage (320).

Meanwhile, an optical fiber (810) is installed in a passage (320) through the rotating cam (300), and the knock cap (200) is formed of a transparent or translucent material so that light transmitted through the optical fiber (810) can be observed from the outside.

Accordingly, the light generated from the LED element (600) can be observed with the naked eye from the outside through the knock cap (200) selected as a transparent or translucent material through the passage (320).

In addition, when an optical fiber (810) is installed in the passage (320), the light generated from the LED element (600) is transmitted through the optical fiber (810) with greater efficiency.

It is already known that optical fibers are made of glass fibers with different densities and refractive indices inside and outside, so that the light that enters them undergoes total reflection and can be transmitted over long distances without loss.

At this time, the color and brightness generated from the LED element (600) are produced according to the consumer's taste or selected and installed from products already available on the market.

In addition, it is disclosed that the surrounding area of the rotating cam (300) and the housing (100) located mainly on the upper body can be formed transparently as a light transmission means (800) so that the light generated from the LED element (600) is emitted to the outside through the rotating cam (300) and the housing (100).

Figures 5 and 6 illustrate a second embodiment according to the present invention.

That is, the rotating cam (300) has a hollow space formed inside it, and the battery (500) is installed with two electrodes facing downward.

In addition, a case (450) for accommodating an LED element (600) is interposed between the above-mentioned rotating cam (300) and the exposed member (110), and a fitting projection (451) is integrally formed in the case (450) so as to be inserted into and connected to the inside of the exposed member (110).

And, a return spring (700) is elastically installed between the case (450) and the rotating cam (300).

This return spring (700) is set to have lower elasticity than the spring (400) for elastically supporting the exposed member (110).

In this second embodiment, the exposed member (110) filled with ink by the light transmission means (800) is made of an optical fiber material so that light can be transmitted to the position of the ball tip (111).

In addition, the light transmission means (800) is formed by embedding a plurality of optical fibers (810) having a small diameter into the interior of the exposed member (110) filled with ink, so that light can be transmitted to the location of the ball tip (111) through the optical fibers (810).

The above light transmission means (800) is formed by molding a case (450) with the above transparent material, and then installing an optical fiber (810) in the passage (320) of the rotating cam (300), and the knock cap (200) is molded with a transparent or semitransparent material so that the light transmitted through the optical fiber (810) can be observed from the case (450) and the outside.

Accordingly, light generated from the LED element (600) can be emitted to the outside through a hole (131) located around the exposed member (110) and the tip (111) connected to the end.

In addition, light can be observed from the outside with the naked eye through the knock cap (200) selected as a transparent or translucent material through the passage (320) of the rotating cam (300).

In addition, when an optical fiber (810) is installed in the passage (320), the light generated from the LED element (600) is transmitted through the optical fiber (810) with greater efficiency.

Meanwhile, it is disclosed that the surrounding area of the rotating cam (300) and the housing (100) located mainly on the upper body can be formed transparently as a light transmission means (800) so that the light generated from the LED element (600) is emitted to the outside through the exposed member (110) and the housing (100). (Fig. 19)

Figures 7 to 9 illustrate a third embodiment according to the present invention.

That is, an exposed member (110) is connected to the lower portion of the above-mentioned rotating cam (300), and a cylindrical support member (330) is provided at the upper portion thereof to accommodate a battery (500).

And, the LED element (600) is mounted on the inside of a knock cap (200) formed in a cap cross-section shape made of transparent material, and an electrode return spring (700) is elastically installed between the LED element (600) and the battery (500).

At this time, an insulating tube (510) is installed on one side of the periphery of the battery (500) to short-circuit the current when it comes into contact with the terminal (620) of the LED element (600).

The LED element (600) positioned in the inner space of the knock cap (200) has terminals (610) (620) installed facing downward, and the terminal (620) positioned toward the outside is formed of a relatively long, elastic, and electrically conductive ferrous metal material.

This long terminal (620) is located on the outer side of the battery (500).

And, an electrode return spring (700) is elastically installed between the battery (500) and the LED element (600).

The return spring (700) for this electrode is set to have lower elasticity than the spring (400) mounted on the lower part of the pen to elastically support the exposed member (110).

Fig. 7 shows a state in which the ball tip (111) is inserted into the nib case (450) just before the knock cap (200) is pressed, and among the two terminals (610) and (620) of the LED element (600), the terminal (620) with a longer length located on the outside is in contact with the insulating tube (510) wrapped around the lower side of the battery (500) to short-circuit the electricity.

The insulating tube (510) is made of synthetic resin or vinyl material and has the function of blocking contact between the outer part of the battery (500) that acts as an electrode and the outer long terminal (620) of the LED element (600).

The return spring (700) for the electrode is compressed by the strong elasticity of the spring (400) mounted at the lower end of the pen, so that even if the central electrode of the battery (500) is in contact with the short terminal (610) of the LED element (600), the LED element (600) is in the off state because the long terminal (620) located on the outside is in contact with the insulating tube (510).

Fig. 8 shows a state in which the knock cap (200) is pressed to expose the ball tip (111) for writing, and the rotary cam (300) is caught by coming into contact with the rising-inducing groove (120) provided inside the housing (100) as it rises, and the knock cap (200), which is free to rise and fall due to the elasticity of the return spring (700) for the electrode, is raised to the maximum.

In this state, the return spring (700) for the electrode made of an electric conductor is in contact with one - electrode protruding from the center of the battery (500) and the central terminal (610) of the LED element (600), and the long outer terminal on the side of the battery (500) is elastically contacted to connect the + electrode, thereby connecting electricity and causing the LED element (600) to emit light.

In this third embodiment, a knock cap (200) is formed of a transparent or translucent material as a light transmission means (800), and light generated from an LED element (600) mounted inside thereof is shined outward through the knock cap (200), thereby allowing the user to observe the light with the naked eye.

At this time, the color and brightness generated from the LED element (600) are produced according to the consumer's taste or selected and installed from products already available on the market.

Figures 10 to 12 illustrate a fourth embodiment according to the present invention.

That is, an exposed member (110) is connected to the lower portion of the above-mentioned rotating cam (300), and a cylindrical support member (330) is provided at the upper portion thereof to accommodate a battery (500).

And, the LED element (600) is mounted on the inside of a knock cap (200) formed in a cap cross-section shape made of transparent material, and an electrode return spring (710) is elastically installed between the LED element (600) and the battery (500).

At this time, an insulating tube (510) is installed on one side of the periphery of the battery (500) to short-circuit the current when it comes into contact with the terminal (620) of the LED element (600).

The LED element (600) positioned in the inner space of the knock cap (200) has terminals (610) (620) installed facing downward, and the terminal (620) positioned toward the outside is formed of a relatively long, elastic, and electrically conductive ferrous metal material.

This long terminal (620) is located on the outer side of the battery (500).

And, an electrode return spring (710) is elastically installed between the battery (500) and the LED element (600).

The return spring (710) for this electrode is set to have lower elasticity than the spring (400) mounted on the lower part of the pen to elastically support the exposed member (110).

Fig. 10 shows a state in which the ball tip (111) is inserted into the nib case (450) just before pressurizing the knock cap (200), and among the two terminals (610) and (620) of the LED element (600), the longer terminal (620) located on the outside is in contact with the insulating tube (510) wrapped around the lower side of the battery (500) to short-circuit the electricity.

The insulating tube (510) is made of synthetic resin or vinyl material and has the function of blocking contact between the outer part of the battery (500) that acts as an electrode and the outer long terminal (620) of the LED element (600).

The return spring (710) for the electrode is compressed by the strong elasticity of the spring (400) mounted at the lower end of the pen, so that even if the central electrode of the battery (500) is in contact with the short terminal (610) of the LED element (600), the LED element (600) is in the off state because the long terminal (620) located on the outside is in contact with the insulating tube (510).

Fig. 11 shows a state in which the knock cap (200) is pressed to expose the ball tip (111) for writing, and the rotary cam (300) is caught by coming into contact with the rising-inducing groove (120) provided inside the housing (100) as it rises, and the knock cap (200), which is free to rise and fall due to the elasticity of the return spring (710) for the electrode, is raised to the maximum.

In this state, the return spring (710) for the electrode made of an electric conductor is in contact with one - electrode protruding from the center of the battery (500) and the central terminal (610) of the LED element (600), and the long outer terminal on the side of the battery (500) is elastically contacted to connect the + electrode, thereby connecting electricity and causing the LED element (600) to emit light, which is the same as in the third embodiment.

And, in order to install the battery (500) and LED element (600) in two groups, upper and lower, respectively, the rotating cam (300) has a hollow space formed at the bottom so that the battery (500) is installed facing downward.

In addition, a case (450) for accommodating a lower portion of a battery (500) and an LED element (600) is interposed between the above-mentioned rotating cam (300) and the exposed member (110). A fitting projection (451) is integrally formed in the case (450) so as to be inserted into and connected to the inside of the exposed member (110).

And, a return spring (700) is elastically installed between the case (450) and the rotating cam (300).

This return spring (700) is also set to have lower elasticity than the spring (400) for elastically supporting the exposed member (110).

Accordingly, the LED element (600) can be turned on/off by operating the knock cap (200) with the same effect as the operation of the second embodiment described above.

In this fourth embodiment, a knock cap (200) is formed of a transparent or translucent material as a light transmission means (800), and light generated from an LED element (600) mounted inside thereof is shined outward through the knock cap (200), thereby allowing the user to observe the light with the naked eye.

In addition, the light transmission means (800) is formed by molding the case (450) with the transparent material, and then installing an optical fiber (810) in the passage (320) of the rotating cam (300), and the knock cap (200) is molded with a transparent or semitransparent material so that the light transmitted through the optical fiber (810) can be observed from the case (450) and the outside.

Accordingly, light generated from the LED element (600) can be emitted to the outside through a hole (131) located around the exposed member (110) and the tip (111) connected to the end.

At this time, the color and brightness generated from the LED element (600) are produced according to the consumer's taste or selected and installed from products already available on the market.

Figures 13 to 15 illustrate a fifth embodiment according to the present invention.

That is, the case (450) is installed on the upper part of the exposed member (110) to accommodate the LED element (600) and is integrally provided with a fitting projection (451) to be inserted and connected into the interior of the exposed member (110), which is the same as in the above embodiments.

And, a connecting body (910) that is inserted and connected into the interior of this case (450), a fixing body (920) that securely installs the battery (500) to prevent movement inside, and a return spring (930) are provided between this connecting body (910) and the fixing body (920). This connecting body (910), the fixing body (920), and the return spring (930) are integrally formed into a single tension module (900) and interposed between the case (450) and the rotating cam (300).

The tension module (900) is formed of a synthetic resin material with excellent elasticity, and the return spring (930) located at the center has elasticity due to the material properties.

A protrusion (921) is provided inside the fixture (920) to support the battery (500).

The case (450) and tension module (900) have the effect of simplifying the parts and improving the assembling efficiency.

The above light transmission means (800) embeds an optical fiber (810) inside an exposed member (110) made of an optical fiber material formed by molding a case (450) with the above transparent material, so that light generated from an LED element (600) can be emitted to the outside through a hole (131) located around a ball tip (111) connected to the end of the case (450) and the exposed member (110).

In addition, it is disclosed that the surrounding area of the rotating cam (300) and the housing (100) located mainly on the upper body can be formed transparently as a light transmission means (800) so that the light generated from the LED element (600) is emitted to the outside through the exposed member (110) and the housing (100). (Fig. 19)

Figure 17 is an enlarged cross-sectional view showing an example in which an optical fiber (810) is formed while being embedded in the cross-sectional portion of an exposed member (110).

Fig. 18 is an enlarged cross-sectional view showing an example in which a slit groove (112) is dug into an exposed member (110) and optical fibers (810) are each installed by fitting into the slit groove (112).

Referring to FIG. 20, the light source of the LED element (600) transmitted to the housing (100) can be observed from the outside of the housing (100) through the light guide film (L-1) formed on the outer surface of the housing (100).

In addition, the light-guiding film (L-1) may be provided at either the outside or inside of the housing (100), or at least at either the inner or outer surface of the exposed member (110), and may be manufactured as an integral or separate type.

When the light-guiding film (L-1) is provided separately on the housing (100) and the exposed member (110), it can be provided on the outer surface of the housing (100) through an adhesive method such as bonding, pressing, or fusion.

This light-guiding film (L-1) can prevent the light source emitted from the LED element (600) to the housing (100) from diffusing to unnecessary locations, thereby increasing the brightness of the light source.

Here, the light guide film (L-1) forms another light guide path (L-2) at at least one location.

The light source (L-2) selectively guides the light emitted by the housing (100) to a specific location, thereby concentrating and emitting artificial light to a location desired by the user, thereby significantly reducing the spread of unnecessary artificial light and increasing brightness.

At this time, it is desirable that the light source (L-2) be formed so that it can emit a certain pattern, character, picture, or other shape toward the outside of the housing, rather than being limited to a scratch.

Here, the artificial light emitted through the light-emitting module (10) is directly transmitted to the exposed member (110) and emits artificial light toward the outer surface of the writing instrument or the ball tip (111).

At this time, it is preferable that the bolt tip (111) be made of a material that receives artificial light emitted through the light-emitting module (10) and emits artificial light.

Although this writing instrument is implemented as a knock pen by pressing an exposed member (110) filled with ink of a single color as in the above-described embodiment, it should be noted that the writing instrument of the present invention can be implemented in various writing instruments, such as a multi-color pen, in which a plurality of exposed members (110) are provided, ink of various colors is filled in the plurality of exposed members (110), and the user presses a button (not shown) to press the exposed members (110) to replace the plurality of exposed members (110).

That is, the present invention is not limited to a knock pen, and can include any writing instrument that allows a user to make a light-emitting module (10) light up with a pressing motion as determined by a person skilled in the art.

Therefore, according to the lighting stick of the present invention, the promotional effect can be increased by emitting artificial light to the outside of the housing through the exposed member, and there is an effect of making it easy to find a writing instrument in a dark place.

In addition, there is an effect of reducing the manufacturing process and manufacturing cost through the tension module being formed as one piece.

The embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.
