WRITING DEVICE, PARTICULARLY CAPACITIVE PENCIL, FOR AFFIXING GRAPHIC SIGNS SUCH AS DRAWINGS AND WRITINGS OF VARIOUS KIND WITH VARIABLE INCLINATIONS ON TO TACTILE SCREENS OR TOUCH SCREENS

Description

[0001] The invention relates to a writing device, in particular capacitive pencil, adapted to affix graphic signs such as drawings and writings of various kind with variable inclinations on to tactile screens or touch screens.

[0002] From DE19731978A1 it is known a quill which includes an elongated element which ranges between far and near ends. Said element has a surface which tapers between the two ends and forms a peak at the far end, furthermore, such an element has an inner volume in which the end of a tracer pin is securely and detachably held using a near opening. The diameter of the inner volume of said element is smaller than the diameter of the tracer pin. Said opening expands laterally due to the diameter differences.

[0003] The elongated element consists at least partly of an elastomer material with a hardness which is less than the hardness of the monitor.

[0004] From US2012194484A1 it is known a stylus comprising a tip and a body, which stylus may be configured to attach to a writing utensil and may be a capacitive stylus for use with a capacitive touch screen. Said tip may be removably attached to said body.

[0005] The object of the present invention is to realize a writing device for affixing graphic signs such as drawings and writings of various kind, with different characters and signs and more or less marked lines and with variable inclinations thereof, on to tactile screens or touch screens, which is made in a manner different than that disclosed by the state of the art represented by the above references.

[0007] In the above Figures, it is schematically illustrated a writing device for affixing graphic signs such as drawings and writings of various kind, having different characters and signs and lines more or less marked and with variable inclinations thereof, on to tactile screens or touch screens of per se known capacitive type, which are utilized alone or combined with informatics appliances such as computers or informatics plants of various kind.

[0008] In particular, such writing device allows to realize and to display on to the tactile screen some graphic signs such as alphabetical letters, technical drawings, designs of furnishings products, various hand made drawings, drawings of cartoons and the like, with more or less marked and shaded signs, which graphic signs may then be memorized into storages included into the same tactile screen, or portable storages such as USB devices and the like, and/or they may be transmitted and made recognizable even on to the screen of other informatics appliances or plants in case utilized.

[0009] In the present description no reference is made to the operation and the construction of the tactile screens or touch screens utilized for affixing and displaying the graphic signs, as they are well known for long time from the art, but it is described exclusively and in detail the writing device of new type according to the invention, and its interaction with the tactile screens for attaining the above mentioned purpose.

[0010] The writing device 5 according to the invention is substantially constituted (see Fig. 1) by at least a pencil 6 acting as capacitive element, and interacting with the capacitors distributed on to the screen outer surface, in order to determine the desired graphic signs by means of instantaneous changes of the capacities of these capacitors, in the areas of the screen which are from time to time contacted by the tip 7 of the pencil, which is constituted by graphite or by charcoal 8, namely by electric conductor material forming the inner core of the pencil, which is enclosed by the lengthened and rectilinear body 9 of the same pencil, and is made of wood, plastic or other electric insulating material, which is grasped by the user and displaced with different movements on to the outer surface of the same screen. The present writing device 5 is also constituted by at least an accessory element 10, which is made separately and is shaped as it will be described, and thereafter is applied removably in correspondence of the tip 7 of the pencil 6, for co-operating with the pencil when the latter is used for writing on to the outer surface of the tactile screen or touch screen 11 (see Figs. 13-15). In the Figs. 1-12 it is shown the configuration of the accessory element 10 in a preferred first embodiment thereof. As visible particularly from the Figs. 1-10, the accessory element 10 is formed by an electric insulating paper element, which is porous, and is constituted substantially by a first widened part 12 having rectangular form and by a second lengthened part 13 having a size smaller than the preceding part, in which the first widened part 12 has a development (see Fig. 5) with the longitudinal sides 14 and lateral sides 15 of a determinate extent, such that they can be wound on itself for forming a cylinder 16 with a length sufficient for being inserted on to the terminal portion of the pencil body 9, upstream the pencil tip 7, and cannot be moved from this position, and that such cylinder 16 has such a diameter that to be able to be at first inserted with a light pressure on to the pencil body 9 and then in case adequately secured on to the same pencil body, for example by a light layer of adhesive. In turn, the second lengthened part 13 is shaped as a narrow rectangular strip 17, an end portion of which is joined integrally with or adequately secured near one of the lateral sides 15 of the first widened part 12, and is extended orthogonally from this latter with a determinate extension, and the other end portion of which is moved away in the longitudinal direction from the first widened part 12 for a determinate length, so as to be able to fold the extended strip 17 many times, in the manner and for the scope which will be described later on. The two longitudinal sides 14 of the so obtained cylinder then are at first slightly overlapped to each other and thereafter suitably joined to each other, preferably by means of an adhesive zone 18 which, as visible from the Fig. 8, is applied along the one of the longitudinal sides 14, in such a way that such longitudinal sides 14 cannot be detached from each other, thereby obtaining a stable cylinder, wherein in the Figs. 9 and 10 there are shown the subsequent steps of sticking such sides of the cylinder. In turn, in the so obtained cylinder the strip 17 is arranged in the central zone thereof, and is projected outward from the lateral side 15 turned toward the tip 7 of the pencil 6. Then, the strip 17 is folded (see Figs. 6, 9 and 10) a first time downward along a first right line 19 in correspondence of said lateral side 15, in a manner to obtain an inclined strip portion 20, and thereafter it is again folded a second time upward along a second right line 21, which is parallel to the first right line 19, in a way to obtain a strip portion 22 slightly raised again, which is shorter than said inclined strip portion 20 and has a relatively wide surface, adapted to come into contact with both the tip 7 of the pencil 6 and the outer surface of the tactile screen or touch screen 11. On to the outer surface of the short strip portion 22 which, as already specified is made of paper material relatively porous, it is applied at least a layer 23 of graphite, charcoal or the like, namely an electric conductor material, on a position turned toward the pencil tip 7, in a manner that when the accessory element 10 is applied on to the free end portion of the pencil 6, by introducing such end portion through the central cavity of the cylinder 16, and by securing adequately this latter (for example by means of adhesive) on to the body 9 of the same pencil (see Fig. 11), by folding suitably the projected and flexible strip 17, such tip 7 may be pushed toward the opposite strip portion 22 and comes into contact of the layer of graphite or charcoal 23 (see Fig. 12), thereby establishing an electric conductor contact between the core of the graphite 8 of the pencil and the layer 23 of electric conductor material.

[0011] In this way, for affixing some graphic signs of various kind (drawings, alphabetical letters, etc..) on to the tactile screen or touch screen 11 it is sufficient (see Fig. 14) at first to bring into contact the core of graphite or charcoal 8 against the conductor layer 23 of the strip portion 22, and thereafter to arrange the opposite surface of this latter into contact against the outer surface of the tactile screen or touch screen 11, and under this condition the graphite or charcoal passes through the pores of the paper material of the strip portion 22, which determines a wide electric conductor contact surface between the graphite or the charcoal and the capacitive areas of the outer surface of the same screen, on to which during the displacements of the tip of the pencil 6 and the strip portion 22 there are produced instantaneous changes of the capacities of the surface areas from time to time interested, with consequent reproduction of the desired graphic signs on to such outer surface. This reproduction effect of the graphic signs with a common pencil, instead of writing devices of traditional type, is made possible thanks to the presence of the present writing device, which allows on the one hand the passage and the contact of the conductor material such as the graphite or the charcoal on to the outer surface of the tactile screen or touch screen 11 and on the other hand a relatively wide contact surface with the tactile screen or touch screen 11, which is greater than that of a pencil tip, which allows to obtain the writing on to the same screen, since in the contrary case the use of the pencil tip only having an extremely reduced contact surface with such screen would not permit to attain such result. Therefore, it appears evident the constructive simplicity of the writing device according to the invention, which is constituted by paper material with a part contacting the screen 11 (strip portion 22), ensuring the continuity of the electric conduction, with an articulation (joining zone of the strip 17 with the cylinder 16) making resilient the same strip and permitting to fold it at will, and with the connection of the accessory element 10 to the pencil body 9, and this writing device operates in an optimum manner and allows to affix on to the screen 11 some graphic signs of any kind, with different markings and shadings, thereby eliminating the need to utilize the complex and expensive writing devices used hitherto for performing the same functions.

[0012] Of course, the present writing device may be realized also with different variants, for example by shaping the accessory element 10 with a profile different than that cylindrical described by way of example only, or by making the accessory element integral with the pencil terminal portion, or with more separated parts which are joined to each other, or by applying in the pencil a suitable anchorage element for the accessory element (by anchoring such accessory element for example by insertion, rolling, fixed joint, sticking, screwing, magnetic attraction, or other suitable systems), and in case by substituting the paper material of the accessory element with another material permeable to the passage of the graphite or charcoal, etc..., thus without departing from the protection sphere of the present invention. The Fig. 13 shows a pencil 6 to be utilized together with the above described accessory element (not visible in the Figure), together with two tactile screens or touch screens 11 with different dimensions, while in the Fig. 14 it is shown the writing device according to the invention in which the pencil 6 is grasped and displaced by the fingers 24 of the hand 25 of a draftsman and/or writer, while the accessory element 10 is put into contact of the screen 11 and is displaced with a determinate inclination on to the same screen, and in the Fig. 15 it is shown the writing device with three different inclinations with respect to the screen 11, for obtaining the graphic signs with the desired markings and shadings. Finally, in the Fig. 16 there are shown some examples of further possible embodiments of the present writing device, in which the accessory element 10 is always constituted by a flexible strip 17 identical to the above one and anchored in different manners to the relative pencil 6. In the Figs. 16a, b, c, d, e, f, g, h there are noted eight different modes of anchorage of the widened part 12 of the accessory element to the pencil 6, and in particular in the Fig. 16 a it is noted that the strip 17 is fixed to the widened part 12, which is shaped as a sleeve formed by two frustums of cone symmetrical and converging to each other with their smaller diameter, into which a through slot 26 is provided for the passage of the opposite end portion of the strip 17, which is adequately fixed to the outer surface of the two frustums of cone referred to.

[0013] In the Fig. 16b it is noted that the strip is fixed with its opposite end portion to a thin circular ring 27, applied to and adequately fixed around the pencil 6. In the Fig. 16c it is noted that the strip 17 is inserted with its opposite end portion through a through slot 28 provided on a clamp 29 wound around the pencil 6, and such end portion is suitably fixed in position. In the Fig. 16d it is noted that the strip 17 is fixed with its opposite end portion, by means of a nail, screw, rivet 30 etc.. on to the pencil body 6.

[0014] In the Fig. 16e it is noted that the strip 17 is joined with its opposite end portion with an indented collar 31, suitably wound and fixed around the pencil 6.

[0015] In the Fig. 16f it is noted that the strip 17 is stuck with its opposite end portion on to the pencil 6. In the Fig. 16g it is noted that the strip 17 is joined with its opposite end portion with a frusto-conical sleeve 32, which is inserted into and adequately secured to the pencil 6. In the Fig. 16h it is noted that the strip 17 is joined integrally with its opposite end portion to the pencil body 6.
