[Detailed description of the invention] (Field of industrial application) The present invention presses the rear end of the cartridge that protrudes from the rear end of the barrel, and connects the engaging part that protrudes from the vertical hole of the barrel to the locking hole at the tip of the clip. This relates to a knob-type writing instrument with a clip that is locked to the cartridge and pulled outward to release the lock and retract the cartridge. If you try to insert the clip into a pocket, etc., the tip of the cartridge will automatically be accommodated in the shaft cylinder to prevent the pocket etc. from being soiled with ink, lead core, etc., and the overall structure will be The aim is to make it extremely simple and inexpensive to manufacture.

(Prior art and its problems) Conventionally, as shown in Japanese Unexamined Patent Publication No. 49-48418, a locking step was provided on the inner surface of the tip of the clip, and the notch of the presser was used to press and move the cursive body toward the tip. The engaging part interlocked with the clip is locked to the locking step part, and by knocking the pusher again, the detachment operating body is pressed and the tip of the clip is pushed outward, thereby causing the engaging part to engage with the clip. Knot-type writing instruments are known in which the tip of the writing body is inserted into the barrel by removing it from the stop, but if the clip swings sideways during writing, the lock is released and the tip of the writing body enters the barrel. It gets stuck, making it impossible to write on it, and when inserting it into a pocket, etc., the locking step provided at the tip of the clip tends to get caught on the edge of the pocket, which causes the front part of the clip to move outward from the barrel. If you have to pull it apart, and if you use it repeatedly, the front part of the clip will become lifted up from the barrel (deformation).
As a result, the locking force between the clip locking stepped portion and the engaging portion becomes extremely weak, and when writing, a light shock causes the tip of the writing body to be pulled into the barrel, making it impossible to write. Ta.

(Means for Solving the Problems) The present invention includes a non-circular ring that is fitted and locked in the narrow diameter portion of the intermediate portion of the cartridge, and an engaging portion protruding from the non-circular ring that protrudes from the vertical hole of the shaft cylinder. This device eliminates the drawbacks of the conventional device through an extremely simple structure in which the rear end of the cartridge is pressed to fit and lock the engaging portion into the locking hole at the tip of the clip.

(Example) Next, an example of the present invention shown in the accompanying drawings will be described in detail. The tip of the clip 2 attached to one side of the outer surface of the barrel 1 has a V section 2a with a V-shaped longitudinal section that contacts or approaches the outer surface of the barrel 1, and the tip of the V section 2a has a A locking hole 2b is provided, and a vertical hole 1a is formed in the shaft cylinder opposite to the locking hole 2b. 3 is a cartridge made of a well-known writing instrument such as a ballpoint pen with a writing part attached to the tip and ink stored inside, or a sharp pencil using a lead lead; a narrow diameter part 3a is formed in the middle part; 3
An elliptical ring 4 having a non-circular cross section is fitted and locked to a, and an engaging portion 4a protruding from the elliptical ring 4 is made to protrude from the vertical hole 1a. When assembling, the elliptical ring 4 is inserted from the rear end of the barrel, the engaging part 4a protrudes from the vertical hole 1a, and held in the state shown in FIG. 1. Next, the cartridge 3 is inserted into the elliptical ring 4 from the rear end of the barrel Press in. A spring 5 is inserted inside the tip of the barrel 1 and constantly presses the cartridge 3 toward the rear end.

(Action) Next, the action will be explained. When the writing part is housed in the barrel, the engaging part 4a is out of the locking hole 2b of the clip 2, as shown in FIG.
The cartridge 3 is pushed to the rear end by the elasticity of the cartridge 3, the tip writing part is retracted into the barrel 1, and the rear end of the cartridge 3 is sufficiently protruded from the rear end of the barrel 1. In this state, insert the clip 2 into a pocket or the like.

Next, when making the writing part protrude from the tip of the barrel,
When the rear end of the cartridge 3 in the state shown in FIG. 1 is pressed against the elasticity of the spring 5, the oval ring 4 fitted and locked in the middle of the cartridge 3 moves forward together.
The engaging portion 4a moves forward in the vertical hole 1a, passes over the V portion 2a of the clip 2, and is fitted and locked into the locking hole 2b as shown in FIG. 3. In this state, the writing portion at the tip of the cartridge 3 protrudes from the tip of the barrel 1, allowing writing.

Next, when you want to retract the writing part at the tip of the cartridge 3 into the barrel 1, either pull the tip of the clip 2 outward with your finger, or insert your finger between the tip of the clip 2 and the barrel 1.
Alternatively, if the engaging portion 4a is removed from the locking hole 2a by pressing the rear end 2c of the clip toward the shaft cylinder,
The cartridge 3 is pushed rearward by a spring 5 within the barrel 1 and returns to its original position as shown in FIG. In this state, insert the clip 2 into a pocket or the like. When replacing the cartridge 3 with a new one, remove the oval ring 4 as shown in FIG. 4 and assemble it as described above.

(Effects of the invention) According to the invention, a locking hole is provided in the clip, a non-circular ring is fitted and locked in the middle part of the cartridge, and an engaging part is provided in the non-circular ring to protrude from the vertical hole of the shaft cylinder, and after the cartridge is inserted. The structure is such that the engaging part is locked into the locking hole of the clip by pressing the end, so if you try to insert the clip into a pocket etc. with a writing instrument in which the tip of the cartridge protrudes from the tip of the barrel, the clip will not lock. The locking hole and the engaging part of the non-circular ring become disengaged, and the cartridge is automatically stored into the barrel by the force of the spring installed in the barrel, so the pocket etc. cannot be used for ink, etc. Since the non-circular ring is fitted and locked to the middle part of the cartridge, assembly is easy, and the overall structure is extremely simple and can be manufactured at low cost. Additionally, the non-circular ring prevents the cartridge from wobbling laterally within the barrel, allowing smooth writing.

Furthermore, since the locking part of the clip is a locking hole instead of a stepped part, when writing, the lock may be released due to sideways movement of the clip, making it impossible to write, and when inserting the clip into a pocket, etc., the clip will not lock. It is also possible to prevent the stopper from easily catching on the edge of the pocket and causing the clip to become loose.

Note that the non-circular ring may be fixed to the cartridge by other means, and furthermore, although the non-circular ring is described as an elliptical ring in this embodiment, it may also be triangular or square as shown in FIGS. 5 to 7. The shape may be polygonal.
