Description

  The present invention relates to a method of using a fountain pen and a weight adjuster for the fountain pen.

Conventionally, a fountain pen has a cylindrical body shaft, a pen core attached to the tip of the fountain pen body, and a cap for protecting the pen core. Fountain pens are roughly classified into a suction type and a cartridge type. In the case of the suction type, ink is stored inside the barrel shaft, and in the case of the cartridge type, ink is stored inside the cartridge or the converter (Patent Document 1). And Patent Document 2).
Fountain pens are generally mass-produced products. For example, in the Slaven series, which is a typical fountain pen made by Pelican, the weight and thickness of the fountain pen are defined at regular intervals.
The fountain pen is formed with a spiral groove for screwing the cap on the tip end side of the barrel shaft to prevent the fountain pen held on the fingertip from slipping with sweat.

However, in the conventional fountain pen, the relationship between the thickness and the weight of the fountain pen is defined in a step shape, and the thickness and the weight are not independent parameters. Therefore, for example, among the lovers of the Slaven series, it has been wondering whether to purchase the Slaven M600 or the Slaven M800. While the Slaven M800 is heavy and the writing speed is insufficient, there are lovers that the Slaven M400 is too light and the writing speed is increased to make it impossible for the clumsy person to write the letters beautifully. The weights of the fountain pens are 16 g, 18 g, and 29 g for Slaven M400, M600, and M800, respectively, and the thicknesses are 13 mm, 14 mm, and 15 mm. In particular, there is a large change in weight between M600 and M800, and those who use the size between them may consider selecting fountain pens from other manufacturers.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method of using a fountain pen and a weight adjustment tool for a fountain pen that can write characters neatly even if the writing speed is increased.

As a result of intensive studies on such problems, the present inventor has found that an adhesive tape can be wound around the rear end side of the barrel shaft of the fountain pen to adjust the weight, thereby completing the present invention. It came to.
The method of using the fountain pen of the present invention is characterized in that an adhesive tape is wound around the rear end side of the barrel shaft for adjusting the weight of the fountain pen. The adhesive tape preferably has an adhesive surface on the back surface and a non-adhesive surface on the surface. For example, when the pressure-sensitive adhesive tape is wound around the rear end side of the barrel shaft, the non-adhesive surface exhibits a non-slip function when the surface is rough.

The weight adjustment tool for a fountain pen according to the present invention is a weight adjustment tool for a fountain pen made of a plurality of rubber tubular members fitted on a barrel shaft, and the plurality of tubular members have different weights. It is characterized by. The cylindrical member may be changed in weight by varying the thickness. And it is preferable to change the color of a cylindrical member according to weight.
Alternatively, the weight adjustment tool for a fountain pen according to the present invention includes a cylindrical member that is externally fitted to the barrel shaft and a weight for weight adjustment, and the cylindrical member is formed with a pocket for attaching the weight. It is characterized by being. It is preferable to prepare a plurality of weights for changing the weight of the fountain pen.

  With the fountain pen usage method and fountain pen weight adjuster of the present invention, it is possible to write characters cleanly even if the writing speed is increased.

FIG. 1 is an explanatory view showing an embodiment of a method of using the fountain pen of the present invention. FIG. 2 is an explanatory view showing a modification of the method of using the fountain pen. FIG. 3 is an explanatory view showing a modification of the method of using the fountain pen. FIG. 4 is an explanatory view showing a weight adjuster for a fountain pen according to the present invention. FIG. 5 is an explanatory view showing a method of using the cylindrical member of FIG. FIG. 6 is an explanatory view showing another embodiment of the weight adjusting tool for a fountain pen according to the present invention.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 shows one embodiment of the method of using the fountain pen of the present invention. The fountain pen 1 of the present embodiment is an ink bottle type and includes a cylindrical body shaft 2 that is slightly curved along the axial direction. Ink is stored in the barrel shaft 2. The ink is sucked by immersing the pen core 4 of the fountain pen in a separately prepared ink bottle and rotating the shaft end 3. The pen core 4 is screwed to the tip of the barrel shaft 2. A noble metal such as 14 gold or 18 gold is used for the pen core 4. An anti-slip spiral groove 2 a is formed in the fingertip clamping portion of the trunk shaft 2. A cap (not shown) for protecting the pen core is screwed into the spiral groove. The spiral groove 2a may be a male spiral or a female spiral.

  A feature of the method of using the fountain pen 1 is that an adhesive tape 5 is wound around the barrel shaft for adjusting the weight of the fountain pen 1. The adhesive tape 5 preferably has an adhesive surface on the back surface and a non-adhesive surface on the surface. This is because when double-sided tape is used, dust adheres to the surface, or when the fountain pen 1 is sandwiched, it sticks to the base end of the finger and is difficult to write. For example, a commercially available so-called gum tape can be used.

  The adhesive tape 5 is wound around the rear end side of the trunk shaft 2. Since this portion is located at the base of the index finger when the fountain pen 1 is gripped, the anti-slip function is exhibited when the non-adhesive surface is rough. In order to make the surface rough, for example, shallow irregularities such as so-called gummed tape may be formed. Alternatively, a tape whose surface is embossed or a rigid resin film whose surface is roughed with a file can be used. Alternatively, a mesh cloth, resin, metal, or the like can be applied to the adhesive tape itself. In short, it is only necessary to increase the weight of the fountain pen 1.

Further, when the adhesive tape 5 is wound around the fountain pen 1, the thickness of the barrel 2 changes, so that the thickness can be easily written by the writer. Further, the weight balance of the fountain pen 1 can be adjusted by the position where the adhesive tape 5 is applied. By adjusting the center of gravity of the fountain pen 1, the fountain pen can be made more suitable for the writer.
As a method of applying the adhesive tape 5, for example, as shown in FIG. 2, a method of wrapping several times perpendicularly to the pen shaft in the circumferential direction, or a method of winding while tilting (tennis racket) as shown in FIG. As in the case of Grip).

FIG. 4 shows a weight adjuster for a fountain pen according to the present invention. As shown in the figure, the weight adjuster is composed of rubber tubes 6A to 6C which are a plurality of cylindrical members having different thicknesses. The rubber tubes 6A to 6C have the same inner diameter and different outer diameters. Therefore, the weights of the rubber tubes 6A to 6C are different.
As shown in FIG. 5, the rubber tubes 6 </ b> A to 6 </ b> C are inserted into the fountain pen 1 from the shaft end side of the fountain pen 1. The rubber tube has flexibility, is easily deformed, and can be fitted to the trunk shaft.

FIG. 6 shows another example of a weight adjusting tool for a fountain pen according to the present invention. As shown in the figure, a pocket 6Da for attaching a weight 7 is formed in the rubber tube 6D, and the weight 7 is inserted into the pocket 6Da. A plurality of types of weights 7 are prepared for changing the weight of the fountain pen, and the weight of the fountain pen can be adjusted by adjusting the weight of the weight 7. Further, from the viewpoint of the stability of the fountain pen, it is preferable to provide a plurality of pockets 6Da around the central axis at regular angular intervals.
In short, the present invention only needs to be configured so that the weight 7 can be attached to the rubber tube 6D.

  The fountain pen of the above-described embodiment can provide a fountain pen with the optimum weight and weight balance for the writer, so that even if the hand is clumsy or the wrist joint is broken, the writing speed is increased. When writing, you can write beautifully.

  Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the essence thereof.

  The present invention can be used for adjusting a fountain pen when the fountain pen is used. For example, it is convenient for adjusting a fountain pen when it is necessary to write many characters in a short time, such as a national qualification examination.
