Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a clock or watch which has a face that changes color due to the time of day and more particularly pertains to a new day and night depicting clock device for demonstrating daytime and nighttime on a clock.




2. Description of the Prior Art




The use of a clock or watch that has a face that changes color due to the time of day is known in the prior art. More specifically, clocks or watches which has a face that changes color due to the time of day are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.




Known prior art includes U.S. Pat. No. 3,777,475; U.S., Pat. No. 3,595,009; U.S. Pat. No. 5,349,572; U.S. Pat. No. 5,586,089; U.S. Pat. No. Des. 251,362; and U.S. Pat. No. Des. 286,755.




While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new day and night depicting clock device. The inventive device includes a clock having a clock face wall and an hour drive shaft rotating once every twelve hours. A first disk is mounted on the hour drive shaft for rotation with the hour drive shaft, has a radially extending first slot, is formed of a resiliently flexible material to permit flexing of a portion of the first disk, and has a relatively light color to identify a daytime period. A second disk is positioned behind the first disk, is fixed against rotation with respect to the clock face wall, has a radially-extending second slot, is formed from a resiliently flexible material to permit flexing of a portion of the second disk, and has a relatively dark color to identify a night-time period. The first disk is movable through the second slot of the second disk. A shifting assembly shifts a portion of one of the disks with respect to another of the disks to cause the first disk to move through the second slot of the second disk to shift the first disk either from a position behind the second disk to a position in front of the second disk or from a position in front of the second disk to a position behind the second disk. An actuating assembly periodically actuates the shifting assembly.




In these respects, the day and night depicting clock device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of demonstrating daytime and nighttime on a clock.




SUMMARY OF THE INVENTION




In view of the foregoing disadvantages inherent in the known types of a clock or watch which has a face that changes color due to the time of day now present in the prior art, the present invention provides a new day and night depicting clock device construction wherein the same can be utilized for demonstrating daytime and night-time on a clock.




The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new day and night depicting clock device which has many of the advantages of the clock or watch which has a face that changes color due to the time of day mentioned heretofore and many novel features that result in a new day and night depicting clock device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art a clock or watch which has a face that changes color due to the time of day, either alone or in any combination thereof.




To attain this, the present invention generally comprises a clock having a clock face wall and an hour drive shaft rotating once every twelve hours. A first disk is mounted on the hour drive shaft for rotation with the hour drive shaft, has a radially extending first slot, is formed of a resiliently flexible material to permit flexing of a portion of the first disk, and has a relatively light color to identify a daytime period. A second disk is positioned behind the first disk, is fixed against rotation with respect to the clock face wall, has a radially-extending second slot, is formed from a resiliently flexible material to permit flexing of a portion of the second disk, and has a relatively dark color to identify a night-time period. The first disk is movable through the second slot of the second disk. A shifting assembly shifts a portion of one of the disks with respect to another of the disks to cause the first disk to move through the second slot of the second disk to shift the first disk either from a position behind the second disk to a position in front of the second disk or from a position in front of the second disk to a position behind the second disk. An actuating assembly periodically actuates the shifting assembly.

DESCRIPTION OF THE PREFERRED EMBODIMENT




With reference now to the drawings, and in particular to

FIGS. 1 through 11

thereof, a new day and night depicting clock device embodying the principles and concepts of the present invention and generally designated by the reference numeral


10


will be described.




A day and night depicting clock device of the present invention includes a clock


12


having a clock body


13


, and the clock body has a clock face wall


14


. The clock may have a clock movement


16


mounted on the clock body with a plurality of concentric drive shafts


18


extending through the clock face wall and including an hour drive shaft


19


rotating once every twelve hours. A pair of time-displaying hands


20


,


22


are mounted on the drive shafts, and an annular bezel


24


may be mounted on the clock body in front of the clock face wall.




A first disk


30


is positioned in front of the clock face wall and mounted on the hour drive shaft


19


for rotation with the hour drive shaft. The first disk includes a first central hole


32


extending through a center of the first disk. A collar


34


may be mounted on the first disk adjacent to the first central hole and may also be mounted on the hour drive shaft. A first slot


36


extends radially in the first disk from the first central hole to an outer edge of the first disk. The first disk is preferably formed out of a resiliently flexible material to permit flexing of a portion of the first disk out of a plane of a remainder portion of the first disk. The first disk also preferably has a relatively light color to identify a daytime (for example, A.M.) period.




A second disk


40


is positioned in front of the clock face wall and behind the first disk


30


. The second disk is fixed against rotation with respect to the clock face wall. This may be accomplished by one or more pins


46


protruding from the clock face wall


14


, and one or more corresponding holes


48


in the second disk receiving the pins. The second disk


40


includes a second central hole


42


extending through a center of the second disk. A second slot


44


extends radially from the second central hole to an outer edge of the second disk. The second disk is preferably formed from a resiliently flexible material to permit flexing of a portion of the second disk out of a plane of a remainder portion of the second disk. The second disk also preferably has a relatively dark color to identify a nighttime (for example, P.M.) period. The second disk may have a diameter greater than a diameter of a first disk for permitting the shifting means to contact the second disk without contacting (and possibly impeding rotation of) the first disk. Also, the smaller diameter of the first disk allows the first disk to rotate without contacting the pins


46


supporting the second disk. The first disk is movable through the second slot of the second disk as the first disk rotates on the hour drive shaft.




Shifting means is provided for shifting a portion of one of the disks with respect to an other of the disks. The shifting means may selectively move a portion of the disks toward the clock face wall to cause the first disk to move through the second slot of the second disk to shift the first disk either from a position behind the second disk to a position in front of the second disk or from a position in front of the second disk to a position behind the second disk.




In one embodiment of the invention, the shifting means comprises a pair of shifting assemblies


50


,


60


. Each of the shifting assemblies is positioned laterally to a twelve o'clock position on the clock face wall so that the shifting assemblies are laterally spaced from each other. A left one


50


of the shifting assemblies is positioned laterally left of the twelve o'clock position and a right one


60


of the shifting assemblies is positioned laterally right of the twelve o'clock position.




Each of the shifting assemblies may comprise a shifting arm


52


,


62


and a shifting solenoid


54


,


64


. The shifting arm is provided for selectively contacting a location on the second disk for shifting the disks toward the clock face wall. The shifting arm may extend over the clock face wall from a position radially outward from the clock face wall, and press against the disks toward the wall


14


. The shifting arm may also be pivotally mounted on the clock body for moving between an active position


56


and a passive position


58


. The active position


56


is relatively closer to the clock face wall


14


than the passive position


58


. The shifting arm may be biased toward the passive position when the shifting solenoid is not energized.




The shifting solenoid


54


,


64


is provided for moving the shifting arm toward the clock face wall, and from the passive position to the active position. The shifting solenoid may be mounted on the clock body adjacent to the clock face wall.




Actuating means may be provided for periodically actuating the shifting means. The actuating means may comprise an electrical actuating circuit for selectively energizing (or providing power to) the shifting solenoid of one of the shifting assemblies to move the respective shifting arm from the passive position to the active position. Which shifting assembly is activated depends upon whether the first disk is positioned substantially in front of or substantially behind the second disk.




The actuating circuit may comprise a pair of electrical contacts


72


A mounted on one side of the second disk and another pair of electrical contacts


72


B mounted on the opposite side of the second disk. One pair


70


A,


72


A of contacts are electrically connected to one of the shifting assemblies, and the other pair


70


B,


72


B of contacts are electrically connected to the other of the shifting assemblies. The contacts are operatively connected to the respective shifting assemblies and a power source such that electrically connecting one of the pairs of contacts completes or closes the electrical circuit of the respective shifting assembly, and causes the shifting solenoid to be energized and the shifting arm to be moved by the solenoid from the passive position to the active position for as long as the circuit is closed. The pair of electrical contacts may be circumferentially spaced from each other on each side of the second disk. Illustratively, radial axes


74


,


75


pass through the electrical contacts define a contact separation angle


76


. The contact separation angle in one illustrative embodiment of the invention measures approximately 5 degrees. Also, a contact bisecting axis


78


bisects the contact separation angle


76


and defines an offset angle


80


with respect to the second slot


44


of the second disk.




The actuating circuit may also include an electrical connector strip


84


A,


84


B mounted on both faces of the first disk for periodically completing or closing one of the actuating circuits of the shifting assemblies. The connector strip


84


A,


84


B is mounted on a face of the first disk at a location that permit the rotating first disk to periodically electrically connect one of the pairs of electrical contacts during rotation of the first disk with respect to the second disk, with the particular circuit being closed depending upon the position of the first disk with respect to the second disk (e.g., in front of or in back of). The connector strip


84


A,


84


B extends along an arc, and illustratively the arc measures approximately 10 degrees. The arc is bisected by a connector bisecting axis


86


, and the connector bisecting axis is offset from the first slot


36


by an angle


90


that is approximately equal to the offset angle


80


of the pair of electrical contacts.




With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.




Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
