Description

Knock-down writing instruments with contamination protection

The present invention relates to a writing implement, and more particularly, a pollution prevention function capable of preventing contamination of clothing and the like by pens by inserting an externally exposed pen region into a pen housing by lifting a clip. It relates to a writing implement provided.

In general, writing instruments have fixed refilling shims and fixed writing instruments which expose or conceal the reticle nibs to the outside by using an opening and closing cap, and by rotating a part of the axis, the refilling cores move linearly, thereby causing the refilling cores to appear in and out. The rotary writing implement may be divided into a knock type writing tool which moves a spring by pressing a part of the shaft to give a refilling lead, and a sliding writing tool which slides the refilling lead to protrude and immerse the refilling lead.

Among them, the knock-type writing implements are convenient because they can simply wreak the refilled feel through the operation of pressing the button portion provided on the upper end of the housing.

When the knock type pen has a button portion provided on the upper end of the housing, the refill tip is protruded to be written, and when the button is pressed once again, the protruding refill tip is retracted into the housing to be stored and protected.

Conventional knock writing instruments are accommodated in the interior of the housing refilled to store the ink, the upper portion of the housing is coupled to the knocking body protrudingly manipulated to the slot formed in the inner wall of the housing. The rotary cam is rotatably disposed between the refill core and the knock body. The knock body and the rotating cam serve to enable the exposure operation of the refill core. A spring is disposed between the housing and the refill core to apply an elastic force to the refill core in a direction in which the refill core retreats into the interior of the housing.

The conventional knock-type writing implements described above have a problem that the user's clothes are contaminated by ink leaking from the refill tip when the pen tip is inserted into the clothes while the pen tip protrudes out of the housing when stored in the pocket of the user's clothes. .

The above-described technical configuration is a background art for helping understanding of the present invention, and does not mean a conventional technology well known in the art.

The stopper protrusion 340 of the button unit 300 is caught in the locking groove 231a of the clip unit 200 when the writing tool refill core 400 is exposed to the outside of the housing 100. Maintain an exposure state of 400.

In this embodiment, the stopper protrusion 340 may be provided on the upper surface of the elastic bar 330, the area of the stopper protrusion 340 in contact with the inclined surface portion 231b of the locking portion 230 is also provided to be inclined stopper projection 340 may be smoothly moved on the inclined surface portion 231b.

In addition, the rear portion of the stopper projection 340 in the present embodiment, as shown by way of example in Figure 3, is provided with a stepped vertically to prevent unintentional detachment of the stopper projection 340 caught in the locking groove 231a. Can be.

The writing tool refill core 400 is, as illustrated in FIG. 3, the writing tool holder 410 having one side fitted to the receiving body 320, and the writing tool holder 410. One side portion is combined with the writing implements member 420 moved with the writing implements holder 410, and the writing implements cover 430 is detachably coupled to the writing implements holder 410 to cover the writing implements member 420 do.

In the present embodiment, the writing implements holder 410 is provided with a plurality of support guides 411 and holder grooves 412, as exemplarily illustrated in FIG. 5. In the present embodiment, the plurality of support guides 411 serve to hold the ink container or ink stand of the writing implement member 420, and the holder groove 412 has a button engaging protrusion 322 provided in the receiving body 320. The fit can be combined.

The handle cover 500 may be detachably fitted to the front outer circumferential surface of the housing 100 and may be made of a material including a rubber material.

In this embodiment, the handle cover 500 may be provided with a handle hole 510, as shown in Figure 2, to improve the grip of the user, the handle hole 510 may be provided in plurality. have.

Hereinafter, the operating state of the present embodiment will be briefly described with reference to the aforementioned drawings.

First, the state illustrated in FIG. 3 is a state in which the writing implement refill core portion 400 is in a state accommodated inside the housing 100 and does not use this embodiment. At this time, the stopper protrusion 340 is spaced apart from the locking groove 231a, as shown in FIG.

In this state, when the exposure body 310 is pressed forward based on FIG. 3, the button unit 300 and the writing implement refill core 400 are moved forward. If the exposure body 310 is continuously pressed, the stopper protrusion 340 stops, ie, hangs on the locking groove 231a of the locking unit 230, and the writing tool member 420 is applied even if a force is applied to the writing tool member 420. Can maintain a fixed position.

Finally, when the clip plate 220 is lifted upward in order to release the stopper protrusion 340, the stopper protrusion 340 is released, and the contracted spring S is expanded. While pushing the writing implements holder 410 rearward. As a result, the writing implement refill nib 400 and the button unit 300 are moved to their original positions so that the writing implement refill nib 400 is housed inside the housing 100.

As described above, in the present embodiment, when the clip unit is fastened to a wearing object including clothes, the writing tool is refilled when the clip plate is lifted in the process of being inserted into the wearing object and the stopper protrusion is released to expose the outside. The part is automatically introduced into the housing to prevent contamination of the object to be worn.
