Description

1.- "Ballpoint pen with ink reserve cartridge supported

  The invention relates to a ballpoint pen provided with an ink reserve cartridge that is elastically supported. To date, the ball pens are made in such a way that a pressure of the hand exerted on a scripting ball mounted in an envelope of the stylograph and transmitted through various functional elements of a moving mechanism is

  intensity corresponding to the pressure exerted

  vidually by the act of writing springs that limit

  Attempt the extreme positions of the reserve cartridge dent cre in the envelope of the stylograph simply have this role

  limiting the movement and have no effect of

  tr 8 on the pressure exerted by the hand on the ball of

the cartridge.

  The writing operation of a stylograph

  in principle, in the fact that a ball

  in a seat of the stylograph carries a script pulp of a tank on the paper A rotation of the

  ball is required to perform 19 writing

  the rotation of the ball, it is necessary that the friction on the paper is greater than the friction in the

  its seat inside the point scriptriceo Being don-

  Although the friction of the ball in its seat is of great constant magnitude, but the friction of the ball on the paper is directly proportional to the force which is applied to the ball when writing, it is evident that there is some minimal force with which one has to press the stylograph on the paper so that the ball

  turns and is reliable for writing.

  The lower the force required, the softer the writing. The scribe tip slides even on the paper, the writing is less tiring and can be considered as high quality. Various means can be used to guarantee these advantages. a lower friction of the ball in its seat, it is used balls made especially of a hard and slippery material, such as, for example, austenitic steel> sapphire, corundum, carbides such as carbide of tungsten and others, which also increases the life of the ball and the permanence of its shape On the other hand, the ball seat is made of specially made materials

hard and slippery.

  In order to increase the friction of the ball on the paper and to transfer the ink paste more effectively onto the paper, it is known to use beads having a porous surface to facilitate the application of the pie on the paper However, all these measurements do not solve the mainly physiological factor which affects the effort of maintaining the tip of the stylograph downwards resulting in fatigue. of the hand to write When moving the stylograph to the person writing,

  the tip leaves its contact with the paper, the

  strength, that is, the strength component

  the point is pressed on the paper This is the main factor causing the fatigue of the hand to write, as well as any subjective feeling that the act of writing is tiring, that the slip on the paper is not soft enough, etc. The principle is that, to control the increased vertical pressure of resistance to writing, it is necessary that the stylograph be kept tightly pressed in the fingers, so that the hand is more tired When the stylograph is raised, the fingers have to move upwards which represents an additional increase in the

fatigue by stiffening the tendons.

  The above disadvantages, as well as increased expenses by the choice of special materials and

  This is achieved by the fact that the ink reserve cartridge is not fixed on a seat, so that, in the case of increased pressure exerted by the hand, it can be moved partially backward, which decreases both the effort of the fingers

  These two operations are carried out by means of the displacement mechanism By rotating the lower part 2 of the casing, the spring mono-element 13 is also rotated in the grid 11 at the same time as the body 8 and, in their movement of rotation, they move upwards on the spiral segments 12 against the pressure of the compression spring 17, or in a same downward spiral movement, in the opposite direction of the pressure of the spring 17.
