DIAL CLOCK WITH COUNTER-ROTATING INDICATORS

Abstract

A clock comprises a dial comprising two or more positions. Each position has an associated time value and the associated time values of the two or more positions increase in a first clock direction around the dial. An indicator provided in combination with the dial indicates a position on the dial with respect to the two or more markings that represents a time. An actuator provides a motive force to move the indicator from one position to another position on the dial under the control of a controller so that the indicator transitions from a first time to a later second time by moving the indicator in a second clock direction opposite the first clock direction around the dial. The clock can comprise one or more indicators, actuators, and sensors for sensing the position of each indicator. Indicators can be clock hands, for example minute, hour, or second hands.

DETAILED DESCRIPTION OF EMBODIMENTS

[0026] Clocks are generally instruments for measuring and recording time, especially by mechanical or electronic means, usually with hands or changing numbers to indicate a time, for example the present hour, minute, and sometimes second, or even portions of a second. As shown in FIG. 1, embodiments of the present disclosure provide a clock 10 comprising a dial 20 comprising two or more positions or locations indicated in the figures by markings 30. Each position has an associated time value that can be indicated by a marking 30 and the associated time values of the two or more positions indicated by markings 30 increase in a first clock direction 70 around dial 20. An indicator 40 that rotates about an axis 42 can be provided in combination with dial 20. Indicator 40 indicates a position on dial 20 with respect to two or more markings 30 that specify or correspond to a time. Under the control of a controller 50, an actuator 60 provides a motive force that moves indicator 40 from one position to another position on dial 20 and thereby sets the position and orientation of indicator 40 with respect to the positions indicated by two or more markings 30 so that indicator 40 transitions from representing a first time to representing a second time later than the first time by moving indicator 40 in a second clock direction 72 opposite first clock direction 70 around dial 20. A later second time is a time after or subsequent to the first time. For example, two o'clock is a later time than one o'clock in a single day. For clarity herein, a position or location on dial 20 indicated by a corresponding marking 30 is interchangeably referred to as the corresponding marking 30. A marking 30 can be a mark or marker or other graphic indicator.

[0027] In some embodiments, dial 20 is a clock face and markings 30 are hour markings or minute markings or both. In some embodiments of the present disclosure, clock 10 can comprise first, second, and third indicators 40, 44, 46 for example corresponding to minute, hour, and second hands respectively or any combination of those, as shown in FIG. 2. One or more indicators 40, 44, 46 can, but do not necessarily, rotate about a common axis 42. Markings 30 can be numbers or numerals (as shown in FIG. 1), for example numbers having values associated with a time or time duration. In some embodiments, some markings 30 are ordinal numbers, line segments, dashes, dots or other graphic marks, either with or without explicit values. In some embodiments, some markings 30 are numerals and other markings 30 on the same dial 20 are dots or other non-numeric graphics disposed between numerals. Non-numeric graphic markings 30 can have implicit values provided by cultural context or expectations and are considered herein to have an increase in value in first clock direction 70. For example, a conventional clock can have twelve markings 30 spaced around the center of a clock face. If the twelve markings 30 are numeric, they are generally labelled with the numbers one to twelve (e.g., ‘1’ to ‘12’), with the twelve at the top of the clock face and the numbers one to eleven ordered around the face in a clockwise direction. If the twelve markings 30 are non-numeric, it is understood that each marking 30 is associated with the numbers one to twelve as found on a conventional number clock face of dial 20. In some embodiments of the present disclosure, the positions are implicit and are not indicated with markings 30. In such embodiments, the positions are understood to have implicit values provided by cultural context or expectations or by education. Since users of clock 10 are accustomed to other clocks with markings 30, they implicitly assume the values of the positions, even in the absence of corresponding markings 30.

[0028] As used herein, a dial 20 can be a plate, disk, face, or other surface containing markings 30 or figures upon which the time of day is indicated by hands, pointers, or shadows. Dial 20 can comprise a metal, paper, plastic, wood, cloth, or other surface on which markings 30 are indicated, for example by printed ink, embossings, imprintings, threads, or other graphic markings and can be made using stamping, printing, weaving, sewing or other known manufacturing or construction methods. In some embodiments, indicators 40 are metal, wooden, or plastic pointers having a length greater than a width and a thickness less than the width that extends from an axis 42 to, beyond, or at least partly towards markings 30. Indicator 40 can rotate about axis 42 under the control of controller 50 and by the motive force of actuator 60.

[0029] In some embodiments, first clock direction 70 is a clockwise direction and second clock direction 72 is a counterclockwise direction (as shown in FIG. 1). In some embodiments, first clock direction 70 is a counterclockwise direction and second clock direction 72 is a clockwise direction (as shown in FIG. 3). Indicator 40 can move fewer than 360 degrees around dial 20, for example can move substantially 354 degrees in second clock direction 72 around dial 20. A substantial movement is one made within the limitations of a manufacturing process or a control mechanism and is not necessarily exact. An indicator 40 rotation of 354 degrees is 59/60 of a complete rotation (360 degrees) around dial 20 and therefore corresponds to a movement on dial 20 corresponding to a time period of 59 minutes. A rotation of indicator 40 corresponding to a time period of 59 minutes in second clock direction 72 is equivalent to rotating indicator 40 an amount corresponding to a time period of one (1) minute in first clock direction 70.

[0030] In some embodiments of the present disclosure and as shown in both FIGS. 1 and 2, indicator 40 is a first indicator 40 and clock 10 comprises a second indicator 44 provided in combination with dial 20. Second indicator 44 indicates a position on dial 20 with respect to the two or more positions 30 that specifies a time. For example, first indicator 40 can be a minute hand and second indicator 44 can be an hour hand. In some embodiments, first or second indicators 40, 44, or third indicator 46, can be a second hand (not shown in the figures). A first position 30 of the two or more positions 30 can have a first associated value and a second position 30 of the two or more positions 30 can have a second associated value greater than the first associated value. In embodiments, second indicator 44 moves from first position 30 to second position 30 in either first or second clock directions 70, 72.

[0031] Second indicator 44 can move fewer than 360 degrees, for example, can move substantially 330 degrees in second clock direction 72 around dial 20. A second indicator 44 rotation of 330 degrees is eleven twelfths of a complete rotation (360 degrees) around dial 20 and therefore corresponds to a movement of second indicator 44 corresponding to a time period of 11 hours on dial 20. A rotation of second indicator 44 corresponding to a time period of 11 hours in second clock direction 72 is equivalent to a movement of second indicator 44 corresponding to a time period of one (1) hour in first clock direction 70.

[0032] In some embodiments, clock 10 transitions from representing a first time to representing a second time later than the first time by moving second indicator 44 in first clock direction 70 (e.g., from first position 30 to second position 30). In some embodiments, clock 10 transitions from representing a first time to representing a second time later than the first time by moving second indicator 44 in second clock direction 72. For example, an hour hand (e.g., second indicator 44) can rotate in a counterclockwise direction for 11/12 of a complete rotation to move from an hour to an immediately successive hour. By moving second indicator 44 in a counterclockwise direction, a clock 10 observer can derive additional interest, novelty, enjoyment, and entertainment from clock 10.

[0033] In some embodiments, second indicator 44 moves in first clock direction 70 from a first time to a second time for some portion of a time period defined by the time difference between the first and second times. For the remaining portion of the time period, second indicator 44 moves in second clock direction 72. For example, a minute hand can move in first clock direction 70 (e.g., a clockwise direction) for the first 59 minutes and 59 seconds of an hour and then rotates in second clock direction 72 (e.g., a counterclockwise direction) for the remaining second in the hour.

[0034] In some embodiments, as shown for example in FIG. 4, indicator 40 is a first indicator 40 and clock 10 comprises a second indicator 44 provided in combination with dial 20. Actuator 60 provides a motive force to indirectly move first indicator 40 and second indicator 44 through any combination of gears 80, pulleys, linkages, couplers or magnets. As shown in FIG. 5, in some embodiments indicator 40 is directly driven by actuator 60.

[0035] In some embodiments of the present disclosure, as shown in FIGS. 1-5, actuator 60 comprises any one or combination of a brushed motor, a brushless motor, a stepper motor, a synchronous motor, a hydraulic motor, an escapement, a pendulum with weights, a solenoid, or a spring.

[0036] As shown in FIG. 6, in some embodiments of clock 10 actuator 60, controlled by controller 50, is a first actuator 60 and indicator 40 is a first indicator 40. Clock 10 can comprise a second indicator 44 provided in combination with dial 20 and a second actuator 62, controlled by controller 50, that provides a motive force to move second indicator 44. First and second indicators 40, 44 are therefore capable of independent movement, adding novelty, increased interest, and entertainment to clocks 10 of the present disclosure.

[0037] In some embodiments of the disclosure, as shown in FIG. 6, second actuator 62 comprises any one or combination of a brushed motor, a brushless motor, a stepper motor, a synchronous motor, a hydraulic motor, an escapement, a pendulum with weights, a solenoid, or a spring. In some embodiments, both first actuator 60 and second actuator 62 comprise any one or combination of a brushed motor, a brushless motor, a stepper motor, a synchronous motor, a hydraulic motor, an escapement, a pendulum with weights, a solenoid, or a spring.

[0038] As shown in FIG. 7, clock 10 comprises a sensor 90 that senses a rotational position of indicator 40 by any method, including, but not limited to optical, magnetic, resistive, capacitive, electrical contact or servo-motor feedback. In some embodiments and as shown in FIG. 7, indicator 40 is a first indicator, sensor 90, is a first sensor 90, and clock 10 comprises a second indicator 44 provided in combination with dial 20 and a second sensor 92 that senses the rotational position of second indicator 44 by any method, including, but not limited to optical, magnetic, resistive, capacitive, electrical contact or servo-motor feedback.

[0039] In some embodiments and as shown in FIG. 1, indicator 40 is a first indicator 40 and clock 10 comprises a second indicator 44 provided in combination with dial 20, and first and second indicators 40, 44 rotate about a common axis 42.

[0040] As shown in FIG. 8, indicator 40 is a first indicator 40 and clock 10 comprises a second indicator 44 provided in combination with dial 20. First indicator 40 rotates about axis 4 and second indicator 44 rotates about a different axis 43.

[0041] In some embodiments of clock 10, each position of the two or more positions is indicated with a mark on dial 20, at least one but less than all positions of the two or more positions are indicated with a mark on dial 20, or each position of the two or more positions is not indicated on dial 20. In some embodiments, all of markings 30 are a numeral, all of markings 30 are a dot, or all of markings 30 are a dash. In some embodiments, some but not all of markings 30 are a numeral, some but not all of markings 30 are a dot, or some but not all of markings 30 are a dash.

[0042] Having described certain embodiments, it will now become apparent to one of skill in the art that other embodiments incorporating the concepts of the disclosure may be used. Therefore, the invention should not be limited to the described embodiments, but rather should be limited only by the spirit and scope of the following claims.
