Definitions

  • ABSTRACT A calendar display mechanism adapted to be mounted on the wrist band of a watch or similar device comprising a unitary casing having a curvature on the undersurface adapted to conform to the curvature of the wrist band, the upper surface of the casing providing in its intermediate portion a display area over which a flexible calendar may pass.
  • a hollow cylindrical portion is provided to house the opposite ends of the calendar strip and spindles are mounted coaxially therein to store and afford displacement of the strip to thereby enable display of the different portions of the strip containing different months.
  • the spindles are provided with exterior knobs at one end and are journaled in the endwalls of the hollow cylindrical portions of the casing.
  • the present invention relates to calendars and more particularly to a year calendar of the kind comprising a flexible band provided with successive representations of month calandars, which band is wound up upon shafts, rollers, drums or the like which by rotation can display said calendars at a reading position.
  • the calendar thereby always will be in double meaning at hand, it being possible to read it just as well as a wrist-watch.
  • the calendar with advantage can be secured to the strap of a wrist-watch for instance immediately in front of the watch itself. Not only the hour but also all the data from the calendar are available.
  • FIG. 1 shows a cross-section through a calendar arrangement according to the invention on an enlarged scale.
  • FIG. 2 shows the calendar of FIG. 1 as seen in perspective and on somewhat reduced scale, but larger than the natural.
  • the calendar according to the example shown consists of a casing 1 which has a curved form corresponding to the curvature of a wrist-watch strap or a bracelet.
  • the casing l is provided with cylindrical parts 2.
  • the casing is provided with guiding and reinforcing edges 1.
  • shafts or drums 4 are arranged on which a flexible band 5 is wound up.
  • At the one side of said band is printed monthly calendar representations in a way known per se, one of which is seen from FIG. 2 displaying the month of March.
  • the cylindrical parts 2 of the casing are at the one side provided with passages for shaft journals or the like provided with the set knobs 8 whereby one can bring the desired month to appear at the curved intermediate part 1 of the casmg.
  • the intermediate part 1 can be provided with a transparent cover (not shown). If the band carrying the calendar prints is made from water resistant plastic material such cover is superfluous.
  • the casing is as shown provided with securing clips 7 which in FIG. 2 are shown bent in at the lower surface of a waist-watch strap 9 or the like.
  • the casing can be made from artificial material, light metal or the like.
  • the calendar according to the invention can be made as a once-for-all device which is discarded after use, or it can be so arranged that for example the one of the end walls of each circular part 2 is secured thereto by a snap latch and thus can be removed to change calendar band.
  • a calendar display device for attachment to an arcuate strap adapted to encircle the wrist comprising:
  • an elongated, generally-rectangular, one-piece display casing having cylindrical hollow portions at the opposite ends thereof and an intermediate portion having an arcuate under side conforming to the arcuate form of said strap and an upper side constituting a display backing surface area,
  • an elongated flexible calendar band in strip form and having indicia providing a series of month calendars therealong, the respective opposite ends of said strip being wound around and secured to the shafts mounted in said opposite end hollow portions,
  • each of said cylindrical hollow portions having coaxial end passages rotatably mounting its associated shaft to journal the same for rotation therein, and an axially-extending slot in the cylindrical wall thereof adjacent said display surface area to afford passage of said calendar band outwardly from within one of said hollow portions through its associated slot, across said display surface area, and inwardly into the other hollow portion through its associated slot,
  • each of said shafts projecting through the end passages of the hollow portions and terminating in a knob exteriorly of said display casing whereby each I of said shafts may be manually rotated to displace the flexible calendar band across said display surface area for displaying a selected portion of said indicia.
  • a calendar display mechanism including a transparent cover for the central portion of said casing to overlie the flexible calendar band displayed thereon.
  • a calendar display mechanism according to claim 1 wherein said attaching means includes a pair of clips mounted on said intermediate portion and extending outwardly therefrom to bend around the wrist strap and to engage the undersurface thereof, thereby to mount the display mechanism on said strap.
