Abstract
Description
- The present innovation relates to a ribbon informative barrel for writing instruments.
- From the U.S. patent No. 2,191,662 there is known a ribbon informative barrel for writing instruments comprising: a barrel provided with a window; a ribbon set inside the barrel for scrolling in front of the window; two shafts, which are mounted so that they can turn about their own axes inside the barrel and are fixed to respective end portions of the ribbon for taking up complementary portions of the ribbon itself; and a kinematic chain for movement of the shafts themselves, which is set in the barrel and which in turn comprises: a pinion for each shaft fitted on the corresponding shaft in a position axially fixed and staggered with respect to the pinion of the other shaft; a control pinion, which can move axially against the action of a helical spring and which can selectively engage with the pinions of the two shafts; and a control element, which is axially and radially fixed to the control pinion and is designed to be actuated manually from outside the barrel.
- The ribbon informative barrel for writing instruments described in the U.S. patent cited above presents some drawbacks, which are basically due to the axially staggered position of the pinions of the shafts. In fact, the axial staggering of these pinions necessarily implies the adoption both of a barrel having a considerable axial dimension and of the helical spring for re-positioning the control pinion in one of its initial positions, as well as leading to wear of the pinions owing to the coupling of an axial type, to which they are subjected whenever it is necessary to bring about scrolling of the ribbon in front of the window.
- The purpose of the present innovation is to provide a ribbon informative barrel for writing instruments, which will be free from the drawbacks described above.
- According to the present innovation, there is provided a ribbon informative barrel for writing instruments comprising: a barrel provided with a window; a ribbon set inside the barrel for scrolling in front of the window; two shafts, which are mounted so that they can turn about their own axes inside the barrel and are fixed to respective end portions of the ribbon for taking up complementary portions of the ribbon itself; and a kinematic chain for movement of the shafts themselves, which in turn comprises: a pinion for each shaft; a control pinion, which can be selectively engaged with the pinions of the two shafts; and a control element fixed to the control pinion and designed to be actuated manually from outside the barrel; the informative barrel being characterized in that the pinions of the two shafts and the control pinion are set on one and the same plane of selection transverse to a longitudinal axis of the barrel, the control pinion being angularly mobile about said axis for engaging the pinions of the two shafts at the front.
- The innovation will now be described with reference to the attached drawings, which illustrate a non-limiting example of embodiment thereof and in which:
- Figure 1 illustrates, in side elevation, a preferred embodiment of a ribbon informative barrel for writing instruments according to the present innovation;
- Figures 2 and 3 are views, in longitudinal median section according to two respective planes transverse with respect to one another, of the ribbon informative barrel of Figure 1;
- Figures 4, 5 and 6 illustrate, at an enlarged scale and with parts in cross-sectional view and parts removed for reasons of clarity, three operating positions of an item of the ribbon informative barrel of Figure 1;
- Figures 7-10 are cross-sectional views according to the lines VII-VII and X-X of Figure 3; and
- Figures 11 and 12 are side elevations of two details of the ribbon informative barrel of Figure 2.
- With reference to Figures 1, 2 and 3, the number 1 designates as a whole a ribbon informative barrel for a
writing instrument 2. - The informative barrel 1 comprises a
barrel 3 provided with aside window 4 and with twoend portions window 4 along a longitudinal axis A of thebarrel 3 itself, and of which theportion 6 can be assembled on thewriting instrument 2. Eachportion respective flange 7 and 8, which is transverse to the axis A and has twoholes 9 made on eachflange 7, 8 on opposite sides of the axis A. - The informative barrel 1 moreover comprises: a
ribbon 10, which is set inside thebarrel 3 for scrolling in front of thewindow 4; and twoshafts 11, which are mounted parallel to one another and to the axis A, with their own opposite ends inserted in such a way that they can turn inside theholes 9, and are glued to respective end portions 12 (Figure 7) of theribbon 10 for taking up on themselves complementary portions of theribbon 10 itself. - For scrolling of the
ribbon 10, according to what is illustrated more clearly in Figures 7-10, the informative barrel 1 moreover comprises akinematic chain 13 for movement of theshafts 11, which in turn comprises: apinion 14 for eachshaft 11; acontrol pinion 15, which can be selectively engaged with thepinions 14; and acontrol element 16, which is fixed to thecontrol pinion 15 and is designed to be actuated manually from outside thebarrel 3. - According to what is also illustrated in Figure 11, the
pinions 14 form a single structure with thecorresponding shafts 11 and are set in one and the same selection plane P, which is transverse to the axis A and is identified by a supporting flange 17, which is set substantially in a position corresponding to theportion 5 directly facing theflange 7, and is provided with a semicircular slot 18 and with two throughholes 19, which are engaged by theshafts 11 in such a way as to enable rotation thereof. - According to what is also illustrated in Figure 12, the
pinion 15 is also set in the plane P and has two axial end portions 20, engaged in a slidable way in the slot 18 and in aslot 21, which is similar to the slot 18, and is made in theflange 7. The shape of theslots 18 and 21 is such as to enable angular movement of thepinion 15 about the axis A in such a way as to cause thepinion 15 itself to engage thepinions 14 at the front, so enabling selective rotation of the twoshafts 11. - The
control element 16 is defined by a ring, which is mounted in such a way as to enable its rotation on theportion 5 of thebarrel 3, and has an internal toothing 22, which always remains engaged with thepinion 15. - The
ring 16 may have an external knurling for facilitating gripping thereof and is axially blocked on theportion 5 by aclosing plug 23, which forms part of the informative barrel 1, and comprises a bottom wall defined by theflange 7, and atenon 24 axially inserted in the flange 17. - According to what is illustrated in Figures 4, 5 and 6, free rotation of the
ring 16 about the axis A both in the clockwise direction and in the counterclockwise direction brings about sliding in the plane P of thepinion 15 and drawing of thesame pinion 15 between two alternative positions of arrest (illustrated in Figures 4 and 6), in which thepinion 15 is selectively engaged with just one of thepinions 14, and through an intermediate neutral position (illustrated in Figure 5), in which thepinion 15 is free from thepinions 14. In addition, when thepinion 15 is set in either alternative position of arrest, further rotation of thering 16 about the axis A also brings about rotation of thepinion 15 about its own axis, as well as, consequently, rotation of theshaft 11, thepinion 14 of which meshes with thepinion 15. - Since the two
shafts 11 are set in rotation in directions opposite to one another and since, when onefirst shaft 11 is angularly engaged with thepinion 15 thesecond shaft 11 is instead idle, the rotation of thefirst shaft 11 brings about winding of theribbon 5 onto thefirst shaft 11 and simultaneous unwinding of theribbon 5 off thesecond shaft 11, so enabling reading through thewindow 4 of what appears on the surface of theribbon 5. - In particular, the
ribbon 5 is defined by a film of plastic material, such as polypropylene or polyvinyl chloride, of a thickness smaller than 25 µm, whilst thewindow 4 is obtained by rendering a rectangular portion of thebarrel 3 transparent, and, in order to facilitate reading of theribbon 5, thewindow 4 may also take the form of a cylindrical lens. - Alternatively, according to one embodiment, which is not illustrated but is readily inferable from what is described above, the
window 4 may also be defined by a rectangular opening made through thebarrel 3 to enable direct writing of theribbon 10. - From the foregoing description, it emerges that the informative barrel 1 can be assembled on any
writing instrument 2, such as, for example, a pencil, a fountain pen, or else a ball-point pen having a refill 25 and atubular body 26, which contains the refill 25, and is connected to the informative barrel 1 at theend 6 of the informative barrel 1 itself. - In addition, the informative barrel 1 may also form an integral part of a
writing instrument 2 and be provided together with thewriting instrument 2 itself. - It is understood that the innovation is not limited to the embodiments described and illustrated herein, which are to be considered as examples of embodiment of the ribbon informative barrel for writing instruments, which may, instead, undergo further modifications regarding the embodiments and arrangements of parts, and details of construction and assembly.
