Description

[Detailed Description of the Invention] This invention relates to a fixing device for a clip in a writing instrument such as a fountain pen, a ballpoint pen, or a mechanical pencil.

Up to now, there have been known writing instruments in which a clip is movably attached to the barrel, and when the writing instrument is carried, the clip protrudes largely from the barrel, and when writing, the clip is brought closer to the barrel. For example, JP-A-49-15
No. 519), but in most of these types of devices, the fixing means of the clip and the means for taking in and out the writing tip are connected, so if you accidentally press the clip while carrying the writing instrument, the writing tip may fall out of the barrel. There is a risk that it will protrude and stain or damage clothing, and it is inconvenient that it cannot be applied to writing instruments such as fountain pens where the writing tip cannot be inserted or removed.

On the other hand, in writing instruments in which the clip is not connected to the insertion and removal of the writing tip, the clip C is generally attached to the end of the cylindrical body a, such as the cap or barrel, as shown in FIG. These clips C are fixedly or elastically attached by clips S, etc., but these clips C always protrude largely from the outer surface of the cylinder a, regardless of whether the writing instrument is in use or not, so they cannot be touched by the hand when writing. The disadvantage is that it gets in the way and requires you to change your writing instrument from time to time.

This idea was devised to eliminate the above drawbacks,
When the writing instrument is not in use, the clip protrudes from the outer surface of the cylindrical body to make it easier to attach to clothing, and when the writing instrument is not in use, that is, when it is carried, it is recessed into the cylindrical body so that it does not interfere with writing. Moreover, the present invention provides a clip fixing device that can be applied to a wide range of writing instruments without the fear of the writing tip protruding when carried. The clip is formed into a hook shape by a plate-shaped part whose length and width are slightly smaller than the slit, and a fixing part extending rearward from the upper end of the plate, and a spring is compressed in the horizontal hole provided in the fixing part. At the same time, the slider is fitted and inserted, and a locking part that protrudes downward is provided at the tip, and the upper part of the cylindrical part of the middle ring that fits into the cylindrical body has a vertical part with the same width as the slit in the cylindrical body. A split slit is provided, and the bottom of the vertically split slit has a first
, forming second and third step portions, and providing a flat surface with the same width as the vertical slit on the wall surface on the first step side, and inserting the fixing portion of the clip into the cylindrical body through the slit. It is characterized in that the ring is fitted into the vertical slit of the middle ring, and the locking portion at the tip is engaged with the second and third step portions at the bottom of the vertical slit.

Figure 2 shows an exploded example of this invention.
Reference numeral 1 denotes an elongated cylindrical body serving as a cap or barrel of a writing instrument, and a slit 2 of a desired length and width is bored along the axis in a part of the side wall so as to sink into the upper end surface 1a.

Reference numeral 3 denotes a middle ring fitted into the cylindrical body 1, and the upper part of the cylindrical part 3a has a vertically divided slit 3 having the same width as the slit 2 of the cylindrical body 1.
It is formed into two forks by b, and is vertically divided) 3b
At the bottom, there are first, second and third step sections 3/, 3//, 3/// which are stepped in three steps, and the wall surface on the side of the highest first step section 3' is vertical. Following the split 1-3b is a flat surface 3C having the same width.

Reference numeral 4 denotes a clip, which has a hook-like shape with a plate-like part 4a for hooking and a fixing part 4b stepped from its upper end and projecting backward, and its length and width are equal to that of the cylindrical body 1. The length and width of the slit 2 are slightly smaller than the length and width of the fixing section 4.
A horizontal hole 4C is bored in b, and a cylindrical slider 5 with a closed tip, which is slightly longer than the horizontal hole 4C, is fitted into this horizontal hole 4C together with a spring 6. It is provided with a locking portion 4d extending downward.

Therefore, the fixing part 4b extending from the rear of the clip 4 is inserted into the cylindrical body 1 through the slit 2, and the plate part 4a is fitted into the slit 2 and held by hand. At this time, the spring 6 is compressed. If the inner ring 3 is inserted into the cylindrical body 1 from below while aligning the position of the flat wall surface 3C with the slit 2, the fixing part of the clip 4 will be fixed. 4b fits into the vertical slit 3b of the middle ring 3, and the locking part 4d at the tip engages with the lowest step 3'' at the bottom of the vertically divided slit 3b as shown in FIG. It is fixed to the cylindrical body 1.

The state shown in FIG. 3 also shows the state in which the writing instrument is used. At this time, the plate-like portion 4a of the clip 4 enters the slit 2 of the cylindrical body 1 and touches the flat surface of the inner ring 3. 3C
Since the clip 4 does not protrude significantly from the outer surface of the cylindrical body 1, even if the cylindrical body 1 is gripped and written, the clip 4 will not hit the hand and become a hindrance.

Furthermore, when the required writing is completed and the paper is stored in the pocket 1 of clothing, etc., if the clip 4 is pushed up in the direction of arrow A in the state shown in FIG. 3, the locking part 4d of the fixing part 4b is The slider 5 comes off from the lowermost step 3"' of the middle ring 3 and expands the spring 6 in the horizontal hole 4C, and at the same time the slider 5 protrudes, and the reaction force pushes the fixing part 4b outward. As shown in FIG.
, the upper part of the clip 4 largely protrudes from the outer surface of the cylindrical body 1, and the writing metal is in a state in use.

In this state, when a force is applied to the upper end 4a' of the clip 4 in the direction of the arrow C toward the cylindrical body 1 against the spring force of the spring 6, the locking part 4d of the fixing part 4b and the middle ring 3 The lower end 4a of the plate-like portion 4a is connected to the uppermost step 3' as a fulcrum.
'' is opened outward, and when the cylindrical body 1 is stored in a pocket of clothing or the like, and the cloth is held between the plate-like portions 4a of the clip 4, the stored state as shown in FIG. 5 is achieved.

When the cylindrical body 1 is removed from a pocket or the like, the plate portion 4a is fitted into the slit 2 of the cylindrical body 1 again by the action of the spring 6, as shown in FIG. 4.

Here, push in the upper end 4a' of the clip 4 until the plate-shaped part 4a abuts against the flat wall surface 3C of the middle ring 3, and further push down the clip 4 in the direction of arrow B while keeping it pushed in, so that the fixing part 4b The locking portion 4d is connected to the lowermost stepped portion 3 of the middle wheel 3.
'', the clip 4 is in the retracted state as shown in FIG. 3.

As described above, according to this invention, a state in which the writing instrument is not in use, with the clip largely protruding from the outer surface of the cylindrical body, and a state in which the writing instrument is in use, in which the clip is inserted into the slit of the cylindrical body. It can be changed into two ways,
When using the writing instrument, the clip does not protrude from the outer surface of the cylindrical body, and unlike conventional products, it does not hit your hand while writing.
It doesn't get in the way, and it's convenient because you don't have to change your writing instrument.Furthermore, it has nothing to do with the insertion and removal of the writing tip, so even if you press the top end of the clip when carrying the writing instrument, the writing tip will not stick out. There is no risk of staining or damaging clothes, and it can be applied to a wide range of writing instruments such as fountain pens, ballpoint pens, and mechanical pencils.
It has the advantage of being easy to assemble.
