Description

Multicolor writing instruments with clips

The present invention relates to a multi-color writing instrument having a clip, and more particularly, a clip attached to the outside of the case when a plurality of pen nibs of different colors are provided in a writing instrument case so that the corresponding pen nib appears and retracts by a lifting operation of a knob. It was invented to ensure convenience in operation by preventing interference in knob operation.

In general, pens for various purposes, including ballpoint pens, are composed of a pen nib, a spring, a knob, etc. in a housing, and expose the nib to the outside while elevating the pen nib in the housing.

In addition to the above-mentioned single-color pen, a multi-color writing instrument capable of simultaneously providing and using various colors in one case has recently been widely used.

The multi-color writing instrument is a sliding method using a knob to expose nibs of a plurality of colors, so that nibs of a color desired by the user are extracted during writing, enabling writing.

In this multi-color writing instrument, several pen nibs 30 are mounted in a limited space of the housing, and a return spring 50 that requires elastic force when the pen nibs 30 protrude and retract, and the upper housing of the body is filled with multi-color ink. Each knob 40 connected to (30) is installed.

The knob 40 slides through a hole provided inside the housing 10 to be moved and released, and when the selected pen nib 30 is moved, the nib located at the tip is exposed to the outside of the writing instrument.

For example, when the user performs blue writing, the operating unit of the blue knob 40 connected to the blue pen core 30 slides downward.

Then, while the return spring 50 is compressed, the selected knob 40 and the pen core 30 move forward in the housing.

The knob 40 slides along the guide hole 11 dug according to the direction and number of the pen cores 30 in the longitudinal direction on the top of the housing 10, and at this time, the knob 40 slides along the guide hole 11 ) While moving slightly into the interior, the core of the pen core 30 protrudes to the outside, so that, for example, a blue ballpoint pen can be written.

The same goes for other colored pen nibs.

In this way, while accommodating blue, red, black, green, and multi-colored pen nibs in one pen housing, the pen nibs of desired colors can be selected and used as a multi-colored writing instrument.

Meanwhile, a clip 20 capable of maintaining elasticity is provided at an outer upper end of the upper housing 10 of the writing instrument.

Depending on the type of writing instrument, a clip is integrally injection-molded from the upper side of the housing 10 to retain elasticity with the elasticity of the synthetic resin material, but recently, a separately manufactured clip 20 is used as a hinge pin ( 21) is assembled to pivot around the center and a separate coil spring 22 is mounted between the housings 10, which is widely used.

Multi-color pens are usually equipped with two to five color pen cores.

In general, when three or less color pen nibs are mounted, the interval between the knobs 40 assembled to be vertically elevated in the housing 10 can be maintained relatively wide, so even if the clip 20 is mounted between the knobs 40, the knob Interference does not occur when the pen core 30 is moved up and down for the pen core 30 to emerge and descend.

However, in the case of a multi-color pen having nibs 30 of four or more colors, the distance between the knobs 40 movably installed in the housing 10 must be designed to be very narrow.

1 is a front view showing a clip 20 of a conventional structure.

In the conventional clip 20, the spring 22 must be inserted inside and installed, and the overall width is constant in order to maintain strength with the hinge pin 21 integrally provided for pivoting, or rather, the upper side is lowered Compared to the left and right, the width is wider.

Therefore, when the pen core 30 and the knobs 40 of four or more color pens are assembled to the housing 10 using a conventional clip as an example, the knobs 40 installed to slide up and down at equal intervals in the upper housing 10 Interference with the clip 20 occurs when the knob 40 is moved up and down due to the narrowing of the arrangement interval.

In particular, when the user moves the knob 40 in contact with the knob 40 with his or her finger, the space where the finger can move is not secured at all, resulting in difficulty in operation and inconvenience due to repeated interference with the clip 20. In addition, there were problems such as feeling pain.

Hereinafter, the configuration of the present invention will be described in detail according to embodiments with reference to the accompanying drawings.

As shown, the multi-colored pen, for example, black, red, blue, green, etc. pen nibs 30 are accommodated in the housing 10 so that the pen nibs 30 of the desired color are ejected by operating the knob 40. is to do

By the push operation of the knob 40, the core of the corresponding color is exposed to the outside to enable writing, and by manipulating the knob 40 of a different color that is not exposed, the color can be replaced or all of the pen cores 30 are inside. It is manipulated so that it can be accepted as

The housing 10 has a hollow cylindrical shape, and a pen nib entrance hole passes through the front end so that the nibs of the color pen nibs 30 can enter and exit from the inside.

The upper portion of the housing 10 is capable of accommodating the pen cores 30 and the return spring 50 in an accommodation space provided therein.

In the upper circumference of the housing 10, guide holes 11 are drilled in the longitudinal direction in consideration of the number of pen nibs 30 installed. By manipulating with a finger, the pen nib 30 is moved forward, and writing is possible in a state where the nib is exposed to the front end of the housing 10.

A support part 12 is provided in the housing 10, and the clip 20 is movably installed around the hinge pin 21, and a spring 22 is assembled between the clip 20 and the housing to maintain elasticity.

Such a clip 20 serves to prevent separation in a state where a multicolored writing instrument is elastically worn in a pocket of clothing, for example.

The pen nibs 30 are filled with at least two or more different color inks to enable writing through the tip of the nib, and the knobs 40 are connected to the pen nib 30 in the longitudinal direction of the guide hole 11. It is installed to be slidably movable with a guide, so that writing can be performed by selecting the pen core 30 of the corresponding color.

That is, when the user wants to use the blue pen nib 30 as an example, when the knob 40 of the corresponding color exposed to the outside of the housing 10 is pressed, it is moved to the guide hole 11 and writing is possible. state will be maintained.

And, in this state, when the knob 40 of the corresponding color is pressed to use the red pen core 30, the jammed state of the blue knob 40 is compressed while the unhung release portion of the red knob 40 is in contact. It returns to its original position by the elasticity of the return spring 50.

Then, as the user continues to move the red knob 40 further, the core of the red pen core 30 protrudes to the outside so that the red ballpoint pen can write.

In this way, while accommodating multi-color pen nibs such as blue, red, and black in one pen housing, it is possible to select a pen nib of a desired color and use it as a multi-color writing instrument.

It is common for a cap to be firmly assembled at the top of the housing 10 to finish the exterior beautifully and to prevent the introduction of foreign substances into the interior.

On the other hand, the clip 20 is located between the knobs 40 that slide up and down on one side or both sides.

Therefore, in order to write by exposing the pen nib, press the knob 40 exposed to the outside of the housing 10 using a finger to descend along the guide hole 11, or the pen nib 30 and the knob ( 40) repeats the rising motion. In particular, when the pen nibs 30 and the knobs 40 of four or more color pens are assembled to the housing 10, the arrangement interval of the knobs 40 installed to slide up and down at equal intervals in the upper housing 10 can be narrowed. there is only

Therefore, interference occurs between the clip 20 and the knob 40 or between the finger and the clip 20 when the knob 40 is moved upward and downward for writing.

At this time, due to repeated interference between the clip 20 and the finger, discomfort and pain are felt.

The present invention is located on one side or both sides of the clip 20 and forms a narrow width portion D1 that is narrow by the length corresponding to the operating range L of the knob 40 that slides up and down to form a wide portion ( It is characterized in that it is molded in a single layer with D2).

Here, it is preferable to form a rounded portion R at the boundary between the narrow width portion D1 and the wide width portion D2 so that a soft touch can be felt without burden when a finger touches it.

In addition, when the number of knobs 40 operated so that the pen nibs 30 installed in the housing 10 are selected between 4 and 5, the narrow width portion D1 of the clip 20 is widened. Part (D2) and is molded to be stepped.

Accordingly, when the knobs 40 disposed in a protruding state around the housing 10 are lifted and moved with a finger, interference with the clip 20 or pain may be prevented, thereby improving operation convenience.
