Definitions
- the present invention relates to a writing device for a pen designer.
- the writing feathers having at their end two beaks separated by a slit.
- This slot has a double function, on the one hand, to give the pen the flexibility desired, on the other hand, to ensure the ink supply of the writing tip.
- the pen is applied against a power supply unit comprising several channels connected to the ink tank and arranged opposite the slot in the pen.
- This slot is generally formed by cutting the pen, using, for example, a grinding wheel or any other instrument of this type, then the beaks of the writing tip are brought into contact with one of the other.
- the grinding wheels used in this technique are particularly fine, it is not possible, for mechanical reasons, to reduce the thickness of the grinding wheels below a certain threshold, corresponding to a width of slot minimum.
- the object of the present invention is to propose a writing device for a pen stylus in which the pen itself comprises a slot of usual dimensions, which can thus be produced by known techniques, but which is equipped with a simple and inexpensive means to implement, in order to limit the soiling by ink spraying when the stylographer is subjected to a shock or sudden impulse.
- the subject of the invention is a writing device for a stylographer comprising an ink supply block and a pen with two nozzles, these two nozzles being separated by a slot, the ink supply of the pen being provided by at least one channel of the power supply unit in communication with an ink tank, on the one hand, and with said slot, on the other hand, this device being characterized in that the internal and / or external faces of the two beaks of the pen comprise, over part of their length, a film of a material compatible with the ink and capable of being wetted by the latter and forming two lips, these lips extending under and / or on the slit and being contiguous in the rest position of the pen.
- the Applicant has established that a feather thus equipped on each of its beaks with a film these films forming at the right of the slot two lips covering the latter in the rest position, prevents accidental soiling of the free surface of the pen, when the pen is subjected to a shock, without however opposing a supply of normal ink to the writing tip.
- Said films can be placed both on the outer face of the pen and on its inner face, between the latter and the feed channel.
- the lips will extend to the writing tip of the pen.
- They may be made of any material compatible with the ink and suitable for being wetted by the latter, possibly after a surface treatment.
- liquid varnishes which one coats the beaks of the feather and which adhere to them while drying. Mention will in particular be made of varnishes based on cellulose acetate or acetobutyrate.
- plastics in particular of the A B S type (acrylonitrile-butadiene-styrene copolymers) or polytetrafluoroethylene, which is optionally treated at the surface in order to increase their wettability.
- a B S type acrylonitrile-butadiene-styrene copolymers
- polytetrafluoroethylene which is optionally treated at the surface in order to increase their wettability.
- the thickness of the film covering the beaks of the pen is not critical. It is generally of the order of a few hundredths to a few tenths of a millimeter.
- the film can be deposited on each of the spouts in continuous form by completely covering the slit of the feather, the film obtained being then cut in line with the slit, either by a tear, following a simple spacing of the spouts of the feather, or by using means known in the art such as laser beam, etc. so as to form two lips, contiguous in the rest position.
- a manufacturing process also falls within the scope of the present invention.
- the feathers forming part of the writing device described above constitute another object of the invention.
- the writing device shown in Figures 1 to 4 comprises, in a manner known per se, a pen 1 supported by an ink supply unit 2, comprising a supply channel 3, which communicates with an ink tank (not shown) and whose free surface is turned towards the internal face of the pen 1.
- the tips 4a and 4b of the pen are coated, on one of their faces - their internal face, in the case of FIGS. 1 to 5, with a film forming two lips, respectively 7a, 7b, of a material compatible with the ink, that is to say chemically inert with respect to it, and wettable by the latter.
- These films extend over at least part of the length of the spouts and are in mutual contact over this entire length, thus covering the slot 5, as seen for example in FIGS. 2 and 4.
- the lips 7a and 7b which cover the slot 5 in the rest position prevent ink splashes through it, without however opposing the ink supply to the pen, and, more particularly , writing tips 6a, 6b.
- the lips 7a, 7b can favor the supply of ink, when the tips 6a and 6b are spaced from one another, when the pen is pressed against the paper (FIG. 3). Indeed, while this spacing normally has the effect of a retraction of the ink film, which then no longer comes into contact with the tips 6a, 6b, it is sufficient, to remedy this drawback, to extend the lips 7a, 7b up to at the end of the pen (see Figure 5, where the bodies already described retain the same reference numbers), to minimize their separation and thus promote the accessibility of the tips 6a, 6b, to the ink film.
- lips 7a or 7b can be indifferently arranged on the internal face or on the external face of the feather (see FIG. 6, on which the organs described above retain the same references assigned to the index '), while performing the same function.
- the invention therefore provides a simple and easy-to-use means for opposing ink splashes, under the effect of a shock, through the slit of a pen of a stylographer, and thus to avoid the dirt on the outside of the feather which usually results.
