Description

[Detailed Description of the Invention] The present invention is characterized in that the tip of the writing body is held by an elastic body, and writing instruments other than fountain pens, such as mechanical pencils, have appropriate elasticity similar to that of the nib of a fountain pen. Toshitomo relates to a storage device held by an elastic body.

Excluding fountain pens (conventional writing instruments do not have adequate elasticity at the tip, and mechanical pencils (a) cannot write smoothly, (b) lead easily breaks, and (c) have to be knocked frequently to draw out the lead.) There were shortcomings in important areas for writing JL. or.

Ballpoint pens, etc. (b) No elasticity at all (b) Hands get tired easily There were drawbacks such as.

The object of the present invention is to eliminate these drawbacks, and at the same time provide a writing instrument other than a fountain pen with a writing feel similar to that of a fountain pen.

There are the following embodiments showing the structure of the present invention, which will be explained with reference to the drawings, and then the operation and effects thereof will be explained.

FIG. 1 is a partial side view A, B, a side sectional view C, D, and a partial perspective view E, F showing the first embodiment; 2 is a plate spring 2' shaped like the tip of a fountain pen, and is provided at the lower end of the main body 1.

(b) The writing body 4 is made into a mechanical pencil 4', which is thinner than the inner diameter of the main body 1, and a certain space is provided between the writing body 1 and the main body 1, and the tip 5 of the mechanical pencil 4' is held by the holding part 3. .

e→The head 6 of the mechanical pencil 4' is supported by a fulcrum 7 provided at the upper end of the main body 1 or at a predetermined position.

In this way, the tip 5 and the head 6 of the mechanical pencil 4' are attached to the lower end of the main body 1, and the holding part 3 of the nib-like plate spring 2' of the fountain pen is attached to the upper end of the main body 1 or a predetermined position. The installation is held and supported by the supporting point 7.

By holding the main body 1 in the same way as a fountain pen and writing, the tip of the fountain pen's nib-like plate spring 2' interlocks with the tip of the mechanical pencil 4' with a certain elasticity depending on the writing pressure. , the tip of a mechanical pencil has the same elasticity as the nib of a fountain pen.

Some conventional mechanical pencils have elasticity that acts up and down, but there are none that have elasticity that acts back and forth in an appropriate manner, like the nib-like leaf spring of a fountain pen.

It is common for writing instruments to be held diagonally to the surface of the paper when writing, and from the point of view of the appropriate IfK response to writing pressure, the tip of a mechanical pencil has the same elasticity as the nib of a fountain pen. It seems more appropriate to do so.

By doing this, (b) Due to its moderate elasticity, it writes smoothly and easily.

(b) Relieve pressure and shock to prevent lead breakage.

(c) You can extend the core a little longer so that it is less likely to break, and you won't have to knock it as often.

) Mechanical pencils with thin leads become easier to use.

At the same time, it eliminates the drawbacks of the conventional mechanical pencil, and at the same time gives a mechanical pencil the writing feel of a fountain pen, making it a companion to conventional technology. The tip of a fountain pen nib-like plate spring is bent, a hole is made in it, a holding part 3 is provided, and a protective cover 10 is provided on the back side, so that it can be used for both hard and soft purposes.

The cylindrical fountain pen nib-shaped plate spring 2' shown in the side view B and side sectional views C and D has the holding part 3 shaped like a cylinder and the other tip part made flat. be.

The side cross-sectional view shows that the head 6 of a mechanical pencil 4', which has a short body with a lead tank 9 protruding like a knock bar, is supported by a fulcrum 7 provided at a predetermined position on the main body 1. It is a companion that is attached so that it does not become fixed.

Further, the coil spring 8 shown in the side sectional views C and D holds down the mechanical pencil 4' so that it is not pushed down.

Note that the fountain pen nib-like plate spring 2I provided with the holding portion 3 at its tip may be split in the same manner as the fountain pen nib.

In addition, the first-part perspective view F shows a simplified version of the holding portion 3 in which a protective cover 10 having a U-shaped tip is provided.

FIGS. 1C and 1D are side sectional views showing the second embodiment, in which the fulcrum 7 provided at the upper end of the main body 1 is made of rubber 7', and supports the head 6 of the mechanical pencil 4'. . This uses the fulcrum 7 as a rubber 7' to support the head 6 of the mechanical pencil 4', eliminating looseness and at the same time holding the mechanical pencil 4'
The tip of the writing instrument is designed to be able to smoothly interlock with the elastic body 2 provided with the holding portion 3 at the tip, thereby enhancing the effectiveness of the writing instrument held by the elastic body of the present invention.

FIG. 2 is a sectional view showing a sixth embodiment, in which an elastic body 2 with a holding part 3 at its tip is formed into an inverted cone-shaped rubber 2'' and is provided at the lower end of the main body 1, and a mechanical pencil 4' This holds the tip 5 of the fountain pen.
The tip of the mechanical pencil 4' is held by the tip of the inverted cone-shaped rubber 2'', which is characterized by its non-directional elasticity, unlike the directional elasticity of the mechanical pencil 4', and its main body 1 By holding it at an angle, the tip of a mechanical pencil 4' becomes in a state similar to having appropriate elasticity, allowing you to write smoothly.Also, this reduces the pressure and shock of the writing, which prevents the lead from breaking. can.

FIG. 6 is a sectional view showing the fourth embodiment, in which the elastic body 2 with the holding part 3 at the tip is made into an inverted cone-shaped rubber 2,
The fulcrum 7 is a resilient adjustment screw 7'' provided at the upper end of the main body 1 to hold and support the tip 5 and head 6 of the mechanical pencil J/.This is the tip 5 of the mechanical pencil 4'. is pushed into the holding part 3 at the tip of the inverted cone-shaped rubber 2'', and the head 6 is supported by an elasticity adjustment screw 7# that is adjusted to give the tip of the mechanical pencil 4' optimum elasticity. , which improves the functionality of the sixth embodiment.

FIG. 4 is a side cross-sectional view showing the fifth embodiment, in which the elastic body 2 with the holding part 3 at its tip is a plate spring 2' shaped like a fountain pen tip, and the basket body 4 is a ballpoint pen 4#. I have to. Similar to the first embodiment, this is a ballpoint pen that has the effect of the nib-like leaf spring 2' of a fountain pen with a holding part 3 at the tip, and by doing so, (a) It becomes easier to define the appropriate elasticity.

(b) It is suitable for long hours of writing as it reduces hand and finger fatigue.

This method eliminates the drawbacks of the conventional technology, while at the same time providing a ballpoint pen with a long-lasting writing quality, which was not possible with conventional technology. FIG. 1A, which also shows the first embodiment;
It protects the tip in the same way as E and F, and at the same time can be used as both hard and soft.

Further, the elastic body 2 having the holding portion 3 at its tip may be made of rubber or a coil spring.

In order to completely protect the tip of the writing instrument held by the elastic body of the present invention, conventional methods such as those used for fountain pens may be appropriately utilized.
