Definitions

  • This invention is concerned with a writing instrument equipped with a world time indicator.
  • a world time indicator incorporated in a writing instrument wherein a world time table is arranged on the peripheral surface of an inner cylinder mounted rotatably within the writing instrument and the outer body of the instrument has view windows serving to display at a glance the standard time of the time zones concerned.
  • This invention is primarily based on the following two findings.
  • areas of the world have their own standard times based on longitude totaling 24 different standard times.
  • the standard time difference is expressed in hours, "minutes” and “seconds" are mostly uniform all over the world. Therefore, the number of minutes and seconds can be determined by the time of the place where one is and only information on the "hour” is necessary in order to know the exact time in another area of the world.
  • a writing instrument such as a ball point pen, propelling pencil and fountain pen are commodities which are normally carried by people in pockets, or handbags or are on a desk for daily use, and are readily available at relatively low prices.
  • This invention based on the above-mentioned findings, combines a world time indicator with a writing instrument. Since the outer body of the writing instrument can be used as part of the indicator arrangement and, in addition, the internal space of the instrument may be effectively utilized to accomodate other parts of the.indicator, a particularly compact design can be acheived. Further, a writing instrument according to the invention has multiple functions in that it serves as a writing means, on the one hand, and a world time indicator, on the other hand.
  • the actuating member such as a push button is efficiently utilized also as an actuator for the world time indicator.
  • An elongate core or ink cartridge with a ball point 2 is housed in a rotatable inner tube 4 which has a cylindrical cavity therethrough.
  • the inner tube 4 is received within a co-axial outer tube 6.
  • a clip 8 for attaching the ball--point pen in position to a pocket of a coat.
  • a tapered, hollow member 10 At the other end of the outer tube 6, there is mounted a tapered, hollow member 10.
  • the core or ink cartridge 2 is resiliently held inside the main body of the ball-point pen which comprises the inner tube 4, the outer tube 6, and the tapered member 10, by means of a compression coil spring 12 bearing against an inside wall of the tapered member 10.
  • a push button 14 is provided at the top end of the main body of the ball-point pen. The push button 14 is permanently subjected to a biassing force towards the outside of the main body of the ball-point pen from a compression coil spring 15 which comes in contact with both the lower edge of the push button 14 and the top end of the inner tube 4.
  • the base part 17 of an actuator 16 accommodating the head of the core or ink cartridge 2 is engaged with the inner tube 4 by means of a spline coupling (not shown) in such a manner that these two parts slide relative to each other upon axial movement of the actuator but rotate together by interlocking with each other when the actuator is turned in the direction of its circumference.
  • the push button 14 has two different functions. In the first place, it is used to rotate the inner tube 4 for time indication. The user holds the push botton in his fingers and rotates it in either direction thereby to rotate the actuator 16, fixed to the push button 14, conjointly through a desired angle so that the inner tube 4 which is coupled with the actuator 16 by a spline is in turn rotated in a desired direction. Another function of the push button is to propel the ink cartridge or core 2 out of the tapered portion of the ball-point pen, when the ball-point pen is to be used as a writing instrument. When the push button 14 is pressed into the body of the ball--point pen by the user's finger, the pointed end of the core 2 is pushed out of the tapered member of the ball-point pen. The core 2 is held in its projected position by a proper stopping mechanism accommodated in the base part 17. In this way, this ball-point pen can perform its original function as a writing instrument.
  • an outer shell or sheath 18 is provided for protection of the main body of the ball-point pen, and is designed to rotate through a fixed angle around the outer tube 6.
  • Rings 20 and 22, located respectively at the upper and lower ends of the inner tube 4, are for keeping the inner tube 4 at a fixed position.
  • a ring 24 secured to the outer tube 6 and rings 26 and 28 secured to the shell 18 are for lateral positioning of the outer shell 18.
  • the outer tube 6 has adjacent to the upper end thereof a slot 30 which extends circumferentially through a certain angle and which engages a projecting tongue 32 formed at the upper end of the protection shell 18. The slot 30 cooperates with the associated tongue 32 thereby guiding the rotation of the outer shell 18 and limiting the rotational angle thereof.
  • a ring 34 is provided for stabilizing the lengthwise movement of the push button 14.
  • Fig. 2 is a perspective view, part cut-away, of the writing instrument of Figure 1, showing the inner tube 4, outer tube 6 and protection shell 18.
  • a plurality of rows of figures 42 are printed on the outer circumference of the inner tube 4.
  • Fig. 3 which is a developed view of the inner tube 4, these rowsof figures are arranged in such a manner as to form, when developed, a table of standard times of selected cities or time zones of the world.
  • Each row of figures 42 consists of twenty four figures corresponding to every hour of the day, arranged in order around the circumference.
  • Each vertical row of figures 42 is for indicating the standard time in a respective one of a number of selected cities of importance throughout the world.
  • the vertical rows of figures 42 are arranged in order across the table according to the time differences between the selected cities.
  • Those figures which are horizontally aligned in the table of Figure 3, that is, in the lengthwise direction of the inner tube 4, indicate the corresponding times in the selected cities at a chosen moment. Therefore, the difference of the positions of the same figures in different rows of the figures 42 corresponds to the difference of standard time among those cities.
  • the outer tube 6 which covers the inner tube 4 has two series of openings or windows 44 of which only the series of openings 44 is visible in Fig. 2.
  • the openings 44 are located so as to correspond to the positions of the rows of figures 42, thereby allowing at-a-glance reading of selected figures from the outside.
  • the openings 44 are aligned along the lengthwise direction of the outer tube 6. Adjacent to each opening 44, the outer tube bears one or more city names, such as TOKYO, NEW YORK, etc., on the surface thereof, the rows of figures in the table corresponding to the local standard time of those cities.
  • the protective shell or sheath 18 is provided with a larger opening 52 for exposing the figures in the rows 42 on the inner tube 4 as well as the city names 46 marked near the openings 44 of the outer tube 6.
  • the opening 52 is set to reveal the figures and city names 46 at an operative position of the time indicator, as shown in Figure 2.
  • the protection shell 18 In its rest position, the protection shell 18 can be turned by holding the protection shell 18 with the fingers of the right hand and holding the outer tube 6 with the fingers of the left hand and by rotating the outer tube 6 through an angle determined by the length of the slot 30 until the figures and the city names 46 are covered for protection.
  • Fig. 4 is a perspective view,part cut-away,of the outer tube shown in Fig. 2 but rotated through an angle, say 75°.
  • another series of openings 54 is formed on the outer tube 6, spaced from the series of openings 44 shown in Fig. 2 and corresponding to the positions of each row of figures 42.
  • City names 56 are also provided near the openings 54.
  • the openings 54 are so positioned that the times indicated therethrough are 5 hours behind those shown in the openings 44. Therefore, the city names indicated near the openings 54 are selected so that their local standard time are 5 hours behind the standard times of the cities indicated in the corresponding openings 44.
  • the openings are not limited to two series. For simpler construction, there may be only one. Additional series of openings will enable indication of time in a larger number of cities where standard times are different. In the embodiment shown in Fig. 2 and 4, there are-14 openings indicating the time of 14 different areas. However, the number of openings is not limited to 14. Furthermore, the number of rows of the figures is not limited to seven; larger or smaller number of rows are also possible.
  • the invention is described with reference to the use of the indicator in a ball-point pen, the invention can also be applied to other writing instruments such as a propelling pencil or fountain pen.
  • this invention can be adapted to a writing instrument of the type which has a cap 62 serving to protect the inner tube 4 as shown in Fig. 5.
  • Fig. 6 shows another form of the world time table that is provided on the circumferential surface of the inner tube.
  • the table comprises seven vertical rows and twelve horizontal lines.
  • Each vertical row is subdivided into two columns of sign groups each consisting of a code ("A" for A.M. and "P” for P.M.) and an hour number from 1 to 12 (the exception to this being the sign groups for A12 and P12-which are replaced by the designations "NOON" and "MID” respectively).
  • the two columns of the same vertical row are spaced from one another in such a manner that any pair of horizontally aligned sign groups from the two columns can be made to appear simultaneously in one window of the outer tube.
  • the two sign groups of each pair represent two adjacent hours of the day while adjacent sign groups in a column represent hours separated by a two-hour interval. Since there are only twelve horizontal lines, this embodiment is particularly suitable for a writing instrument having a smaller diameter.
  • Fig. 7 shows another embodiment of this invention, similar to that shown in Fig. 1, wherein the protection shell 18 is held in position by stop rings 72 and 74 fixed to the outer tube at the upper and lower ends of the outer shell 18.
