Description

Technical field

The invention relates to a writing device, in particular a ball-point pen (pencil), consisting of a body with a writing pad and a protector of the cylindrical part of the pad ended with a writing tip.

BACKGROUND OF THE INVENTION

There are many different writing devices (ballpoint pens) with a ball-point insert now available. They are available in different mechanics - from plug-in push-button mechanisms to simpler, where the insert is replaceable in the handle to non-removable writing devices. disposable. As far as the material is concerned, writing instruments are available in various material designs, mostly made of plastic, but metal or wood are no exception. In the segment of writing instruments equipped with a removable ballpoint pen protector, this concept is both structurally and technologically demanding. In a metal-plastic or wood-plastic material configuration, both removable pads and non-removable writing devices are the source of a large amount of waste that is difficult to recycle or even non-recyclable, resulting in a high environmental burden with a negative impact on the environment.

One of the earliest CS patents 81766 discloses a ballpoint pen comprising a pen cartridge with an ink container, a ball pen, and an ink supply device for a pen ball. The writing pad is replaceable. The advantage is that the case is expandable and retractable, the writing insert with and can be easily removed and replaced and the length of the case is adjustable.

SK UV 345 discloses a transcription pencil consisting of a conventional tubular writing pad and a multi-purpose recyclable handle made of hardened paper, wood, solid wood waste, pulp or other environmentally acceptable material. The advantage is relatively low production costs.

CS P 139732 discloses a multicolored ballpoint pen having a backdrop instead of a tubular mechanism and a grooved guide, thereby simplifying the complex manufacturing process of the mechanism tube.

EP 1 428 683 B1 discloses a writing tool, in particular a ballpoint pen, in which the support member is located and supported on the peripheral wall portion of the button and is supported by the peripheral wall or peripheral wall portion of the button. The result is a simple shape, which can be easily manufactured, in particular as an injection-molded casting, since no supporting wall extending transversely in the center of the button is required, as was the case in the previous arrangements. In addition to writing devices (ballpoint pens) with one writing pad, two writing pads, or later with a stylus for operating the touch screen, the ball pen described in EP 3 375 625 A1 is also known, in which the drawing line width can be varied by means of two writing parts.

The main disadvantage of all the writing devices mentioned above is, in particular, their constructional complexity, since they consist of a relatively large number of parts (parts).

In addition, there is a writing device consisting of three parts - a writing insert body, a writing pad protector and a writing pad. Its main disadvantage is the fact that the protector is detachable and has often been lost during handling, leaving the ball tip unprotected.

The object of the present invention is to provide a writing device (ball pen) which suppresses as far as possible the negative aspects of the prior art writing devices.

The essence of the technical solution

These drawbacks are largely eliminated and the object of the present invention is met by a writing device according to the present invention, which consists essentially of a writing body, an insert and a pad. The body is rounded at one end and provided with a cylindrical opening extending into a recess formed in the body of the writing means, the length of which corresponds to the length of the insert. The insert is terminated with a cylindrical writing tip and is inserted into the recess and the mating cylindrical opening so that the cylindrical tip portion partially protrudes from the cylindrical opening. The inner diameter of the cylindrical bore is such that it fits snugly against the surface of the cylindrical portion of the insert and the recess is such that its walls fit snugly to the insert and the length of the recess corresponds to the length of the insert, thereby self-locking in the writing body. The cylindrical protector with a writing tip has a stop on the inside. A groove is formed on the body of the writing means, on the side of the cylindrical opening, which by means of a stop on the guard defines the movement of the guard over the body. The groove formed on the body of the writing device may have a shape resembling the letter I, L, C or S. The protector has an inner diameter that closely matches the outside diameter of the writing body. By moving the protector from one position to the expensive one, the cylindrical part with the writing tip is exposed or covered.

N K 50073-2019 U1

The writing body may be rounded at both ends. Preferably, the writing body is cylindrical in shape, but may also have a cross-sectional shape, for example, triangular, square, hexagonal, octagonal, elliptical or oval.

The writing device body in a preferred embodiment is terminated by a clip (clip) or a clip (attachment) serves to secure the writing device to a block or other object, for example. The adapter may preferably be a stylus suitable for typing or typing characters on touch screens.

In a preferred embodiment, the cylindrical time (inserts terminated with a ball tip)

The protector has an internal cross-sectional shape corresponding to the shape of the writing device body, is open at both ends, or may have a rounding at one end, copying the rounding at the end of the body, with the rounded end open.

The writing means may have an insert and a pad mounted on both sides of the body. By using inserts filled with different colors, a two-color writing device is obtained.

The writing body of the present invention may be made of a variety of biodegradable materials such as biodegradable plastic, cured paper, wood, solidified wood waste or pulp. A protector can also be made of the same environmentally acceptable material.

The writing body and protector can be made e.g. by compression or other known methods.

The main advantages of the writing device according to the present invention are both its simplicity of construction (consisting of only three parts), which ensures low production costs, and the fact that the biodegradable materials used for its production can be recycled without harmful intermediates, impact on the environment.
