Implementation of the invention

As mentioned above, one of the objectives of the invention is to provide a design of the body of the writing instrument, which allows you to minimize temperature fluctuations within the hollow body of the writing instrument.

It is known that a significant disadvantage when using ballpoint pens or rollerballs is the sensitivity to temperature changes of both the ink paste used in ballpoint pens and the ink supply system in the rollerball.

As the temperature rises, the paste in ballpoint pens heats up, which causes the paste to flow out of the pen, as it becomes less viscous. At the same time, as the temperature decreases, the paste, on the contrary, becomes thicker and, as a result, the ballpoint pen writes poorly. Thick pastes build up on the ball, which causes a lot of paste to build up on the tip of the pen and the pen starts to stain and stain with the paste. This causes the ballpoint pen to write poorly. Unlike ballpoint pens, rollerballs use special ink refills that have a very large capacity. In this case, water-based inks are used as ink in rollerball pens. The quality roller refills have a special very thin ink supply system. The only drawback of this system is that it is sensitive to air temperature. At the same time, a significant increase in temperature can disable this system, in particular, this can lead to drying of the ink.

At the same time, the creation of the design of the body of the writing instrument, which contains a closed insulating air circuit, allows you to minimize temperature differences inside the hollow body of the writing instrument, which in turn reduces the temperature effect on the rod inside the body.

According to the claimed invention, the writing instrument device comprises a body that consists of several elements. As shown in figure 2, the body of the writing instrument consists of the following constituent elements: the lower part, the middle part and the upper part

The lower part of the body consists of three elements: a tip 1, a support element 2 and a sleeve of the lower part 3.

The tip 1 has the shape of a cone (see Fig. 2). In the example shown, the tip 1 is made from a shell of a 7.62 caliber bullet. The bullet shell is cut to the required size. Next, the bullet is polished and ground. Also, the bullet can be subjected to a galvanizing process, for example, for gilding.

The supporting element 2 is made in the form of a tube. In this example, the specified support element 2 is made from a cartridge case (caliber 7.62 × 39). The sleeve body is cut to size. Next, the body of the sleeve is polished and, if necessary, painted.

The bushing of the lower part 3 is made with a thread. The bushing of the lower part 3 is installed on the support element 2 in the form of a permanent connection.

Next, consider the housing element - the middle part. The middle part of the body consists of a sleeve of the middle part 4, an inner tube 5, an outer tube 6.

A feature of the middle part of the handle body is the ability to install two tubes - an inner tube 5 and an outer tube 6 with the creation of an air gap - a closed insulating air circuit - between the walls of tubes 5 and 6. This installation feature is possible by attaching the inner tube 5 and the outer tube 6 to bushing of the middle part 4, which has a complex outer stepped structure.

The bushing of the middle part 4 has an outer stepped surface. The first stage of the sleeve of the middle part 4 has a helical thread, due to which the inner tube 5 is tightly attached to it by means of a threaded connection. The second stage of the bushing of the middle part 4 has a smooth seating surface, on which the outer tube 6 is tightly mounted with an abutment against the fixing shoulder of the third stage of the bushing of the middle part 4. An additional internal thread is also applied to the bushing of the middle part 4 for attaching the lower part of the handle body using the lower part 3.

Now let's look at the next element of the case - the upper part. The upper part of the body consists of a sleeve of the upper part 7, a fixing nut 8, a plug 9, a nozzle 10, a screw 11 and a capsule 12.

The sleeve of the upper part 7 has an outer stepped surface. The first stage of the sleeve of the upper part 7 has a helical thread, due to which the inner tube 5 is tightly attached to it by means of a threaded connection. The second stage of the sleeve of the upper part 7 has a smooth seating surface, on which the outer tube 6 is tightly installed with an abutment against the locking ledge of the third stage of the sleeve of the upper part 7. In turn, the sleeve of the upper part 7 is fixed with a locking nut 8 on one side, and on the other side it abuts end ledge into the nozzle 10. The fixing nut 8 is secured with a plug 9 through a threaded connection 9. The plug 9 is built into the nozzle 10 and fixed in it with a screw 11. In the embodiment under consideration, the nozzle 10 is made from a cartridge case (caliber 7.62 × 39) cut to size. Next, the body of the sleeve is polished and, if necessary, painted. Screw 11 is closed by capsule 12.

The upper part of the body is connected to the middle part using the sleeve of the upper part 7.

Additionally, the writing instrument contains a cap 14 and a writing rod 18.

Cap 14 has a conventional cylindrical shape. Clip 15 is fixed in cap 14. Fixation of the spring assembly of the clip with the clip in the cap 14 is made from the inside using the screw 17. The shape of the clip 15 is made in the form of a weapon, the cartridges of which serve as a base (blank) for parts of the lower part and the upper part of the writing instrument. Clip 15 can be made of any precious metal such as silver, gold, platinum. Also, the clip 15 can be made of any non-precious metal, for example, copper, zinc, nickel, aluminum and an alloy, for example, brass, bronze, nickel silver, cupronickel.

The rod 18 is fixed inside the housing with a plug 9 in the upper part and a spring 13 in the lower part.

The outer tube 6 can be made of any material. For example, in one embodiment, the outer tube 6 can be made of precious metals such as gold, silver or platinum. This tube is available in plastic or non-precious material. It is also possible to make the outer tube 6 made of exotic and valuable wood, for example, American walnut, Karelian birch, oak, ash, etc. Also possible are options for the outer tube 6 made of stone, for example, malachite, jasper, charoite. An option may also be considered in which a notch is made over the entire length of the outer tube 6. The profile of the tube may be different. The inner tube 5 can be made of plastic or non-precious metal.

A method of assembling a writing instrument with the formation of an insulating air gap is described in more detail below.

We start assembling the upper part of the writing instrument body. We install the plug 9 in the nozzle 10 and fix it with the screw 11. The nozzle 10 with the plug 9 installed in it is pushed onto the sleeve of the upper part 7. The sleeve of the upper part 7 is fixed using the fixing nut 8. When screwing the fixing nut 8 onto the plug 9, the sleeve of the upper part is tightly pressed by the end ledge to the wall of the nozzle 10. Next, the inner tube 5 is screwed onto the first step of the sleeve of the upper part 7. The outer tube 6 is put on without fixing the sleeve of the upper part 7. Next, we twist the sleeve of the middle part 4 with the second end of the inner tube 5. Install the outer tube 6 to the second stages of bushings 4 and 7 with the formation of a closed air circuit between the walls of tubes 5 and 6. Tight final fixation of the outer tube 6 is carried out by twisting the sleeve of the middle part 4 and the inner tube 5 until it stops. In this case, the outer tube 6 is more tightly pulled together by the fixing with ledges of the third steps of the bushings of the middle part 4 and the upper part 7. В Inside the body, we install the rod 18 with an emphasis on the plug 9. Spring 13 and the lower part of the body are put on the writing rod 18, which is attached to the rest of the body using a threaded connection of the sleeve of the lower part 3 and the sleeve of the middle part 4.

This body assembly ensures that optimal temperature parameters are maintained within the hollow body of the writing instrument.

In addition, the presence of the outer tube 6 protects the inner body of the writing instrument from mechanical stress (shock, falling, squeezing).

As seen in FIG. 1 and FIG. 2, the body of the writing instrument contains two tubes - an outer tube 6 and an inner tube 5. As can be seen from the drawings, when the outer tube 6 is installed between the inner tube 5 and the outer tube 6, a closed insulating air circuit is created. The air in this volume undergoes a process similar to an adiabatic process, that is, work cannot be done over the air in a closed space (cannot be heated, compressed, etc.), which allows us to maintain the temperature inside the hollow body of the handle. This avoids significant temperature changes inside the hollow pen body, which could affect the ink paste in the ballpoint pen or the ink delivery system in the rollerball.

Making a clip in the form of a weapon, the cartridges of which serve as a base (blank) for parts of the lower and upper parts of the body of the writing instrument allows the user of the pen to more easily identify which cartridges this pen is made of.

The analysis also shows that all the general and particular features of the invention are essential, since each of them is necessary, and all together they are not only sufficient to achieve the purpose of the invention, but also allow the invention to be implemented in an industrial way.
