BACKGROUND OF THE INVENTION-FIELD OF INVENTION
The present invention relates to clocks, specifically to clocks with unique time displays that are interpreted through traditional means.
BACKGROUND OF THE INVENTION
For centuries man has designed and built clocks which served the dual purpose of indicating the current time and adding to the aesthetic decor of an area.
Traditionally, mechanical clocks, whether driven by weights, springs and/or electrical energy, have consisted of a clock face and a number of hands rotating about a central point on the clock face. The hour hand is typically shorter and completes one revolution every twelve hours. The minute hand is typically larger and completes one revolution every sixty minutes. To aid in the user's interpretation of the device, the clock face usually features time demarcations. This configuration is ubiquitous and is popular in architectural clocks, wall clocks, desk clocks, and wrist watches.
Many clock designers, such as in U.S. Pat. No. 2,153,004, by C. H. H. Rodanet, issued Apr. 4, 1939, seek to achieve aesthetic distinction by altering the symbols used on the clock face and/or by designing uniquely shaped hands. That clock also featured hands attached to rotating disks to give the appearance that the hands were floating.
Other clock designers, such as in U.S. Pat. No. 5,999,496, by Y. Chaut, issued Dec. 7, 1999, seek to achieve aesthetic appeal through a unique configuration of elements that do not feature hands or traditional clock faces. While aesthetically striking, these clocks do not allow the use of traditional clock interpretation means to determine the indicated time.
There remains a need, and it would be advantageous to have, clocks which are aesthetically unique and do not possess traditional faces or hands, but nonetheless are interpreted using traditional clock interpretation means.
BACKGROUND OF THE INVENTION-OBJECTS AND ADVANTAGES
Accordingly, objects and advantages of my invention include:
(a) to provide a clock with a unique design which is easily read using traditional clock interpretation means;
(b) to provide a clock where the indicators are set by placing the indicators in the correct orientation, thereby simplifying the clockwork by no longer requiring a clock-setting mechanism;
(c) to provide a clock which is configurable by the reversal or removal of a background ring;
(d) to provide a wall clock which appears to have no supporting frame whatsoever and appears to float and is easily read using traditional clock interpretation means.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

DETAILED DESCRIPTIONS—FIGS. 1 AND 2—PREFERRED EMBODIMENT
A preferred embodiment of the clock with unique time display of the present invention is illustrated in FIG. 1 (front view) and FIG. 2 (section view). The motion of the clock is driven by a clockwork 30 that drives a minute indicator drive wheel 26 and an hour indicator drive wheel 28. The clockwork 30 can be mounted on a wall or a frame to allow the demarcation ring 20, the minute indicator ring 24 and the hour indicator ring 22 to hang freely.
In the preferred embodiment, the demarcation ring 20 has the numerals 3, 6, 9, and 12 placed at their corresponding clock positions to aid the viewer in the determination of the indicated time. Alternately, all of the clock numerals 1 through 12, roman numerals, or other graphic indication could be used on the demarcation ring 20 to aid the viewer in the determination of the indicated time. The demarcation ring 20 is not a driven member and does not move. The demarcation ring 20 rests on the body of the clockwork 30.
In the preferred embodiment, the minute indicator ring 24 and the hour indicator ring 22 are constructed of a clear material which allows for the demarcation ring 20 to be viewed through the minute indicator ring 24 and the hour indicator ring 22. The minute indicator ring 24 has an indicator to denote the minute of the hour. The indicator can be either printed on, attached to, or machined into the minute indicator ring 24. Likewise the hour indicator ring 22 also has an indicator which is smaller than the indicator on the minute indicator ring 24 to denote the hour. The indicator can be either printed on, attached to, or machined into the hour indicator ring 22.
The minute indicator drive wheel 26 and an hour indicator drive wheel 28 have small flanges which keep the minute indicator ring 24 and the hour indicator ring 22 properly aligned with respect to each other and the demarcation ring 20. The clockwork 30 rotationally drives the minute indicator drive wheel 26 at a rate such that the minute indicator ring 24 is rotated 360 degrees every 60 minutes. The clockwork 30 rotationally drives the hour indicator drive wheel 28 at a rate such that the hour indicator ring 22 is rotated 360 degrees every 12 hours. The resulting effect is that the clock has a unique design that does not have the traditional clock hands, yet the time is interpreted using traditional clock interpretation means. In all embodiments, the time is set by manually positioning the time indicating disks, wheels or plates so that the indicators of hour, minute and second are oriented properly. There is no need to have a time adjustment mechanism on the clockworks.
FIGS. 3–16 Additional Embodiments
An additional embodiment is shown in FIG. 3 and FIG. 4. This embodiment is substantially similar to the preferred embodiment but with the addition of a third driven wheel, the seconds indicator drive wheel 42, to a clockwork with support arm 34. The seconds indicator drive wheel 42 is constructed of a clear material which allows for the demarcation ring 20, the minute indicator ring 24, and the hour indicator ring 22 to be viewed through the seconds indicator ring 38. The seconds indicator ring 38 has an indicator to denote the second of the minute. The indicator can be either printed on, attached to, or machined into the seconds indicator ring 38.
The seconds indicator drive wheel 42 has small flanges that keep the seconds indicator ring 38 aligned with respect to the minute indicator ring 24, the hour indicator ring 22, and the demarcation ring 20. The clockwork with support arm 34 rotationally drives the seconds indicator drive wheel 42 at a rate such that the seconds indicator ring 38 is rotated 360 degrees every minute. The clockwork with support arm 34 has a support arm 35 extending from the body of the clockwork and supporting the far end of the drive shaft for the drive wheels 42, 44 and 46. The resulting effect is that the clock has a unique design that does not have the traditional clock hands, yet the time is interpreted using traditional clock interpretation means.
An additional embodiment is shown in FIG. 5 and FIG. 6. In this embodiment of the clock with unique time display the motion of the clock is driven by a clockwork 56 that drives a minute indicator drive wheel 54 and an hour indicator drive wheel 52. The clockwork 56 can be mounted on a wall or a frame to allow the minute indicator ring 50 and the small hour indicator ring 48 to hang freely. The minute indicator ring 50 and the small hour indicator ring 48 are constructed of a opaque material. The minute indicator ring 50 has an indicator to denote the minute of the hour. The indicator can be either printed on, attached to, or machined into the minute indicator ring 50. Likewise the small hour indicator ring 48 also has an indicator which is smaller than the indicator on the minute indicator ring 50 to denote the hour. The indicator can be either printed on, attached to, or machined into the small hour indicator ring 48.
The minute indicator drive wheel 54 and an hour indicator drive wheel 52 have small flanges which keep the minute indicator ring 50 and the small hour indicator ring 48 properly aligned with respect to each other. The clockwork 56 rotationally drives the minute indicator drive wheel 54 at a rate such that the minute indicator ring 50 is rotated 360 degrees every 60 minutes. The clockwork 56 rotationally drives the hour indicator drive wheel 52 at a rate such that the small hour indicator ring 48 is rotated 360 degrees every 12 hours. The small hour indicator ring 48 is sized so that the indicator on the minute indicating ring 50 is not blocked from view. The resulting effect is that the clock has a unique design that does not have the traditional clock hands, yet the time is interpreted using traditional clock interpretation means.
An additional embodiment is shown in FIG. 7 and FIG. 8. In this embodiment the clockwork 56, the minute indicator drive wheel 54 and an hour indicator drive wheel 52 are essentially the same as in the previous embodiment shown in FIG. 5 and FIG. 6. The clockwork 56 can be mounted on a wall or a frame to allow the minute indicator wheel 58 and the hour indicator wheel 60 to hang freely. The minute indicator wheel 58 and the hour indicator wheel 60 are constructed of a opaque material. The minute indicator wheel 58 has an indicator to denote the minute of the hour. The indicator can be either printed on, attached to, or machined into the minute indicator wheel 58. Likewise the hour indicator wheel 60 also has an indicator, which is smaller than the indicator on the minute indicator wheel 58 to denote the hour. The indicator can be either printed on, attached to, or machined into the hour indicator wheel 60.
The clockwork 56 rotationally drives the minute indicator drive wheel 54 at a rate such that the minute indicator wheel 58 is rotated 360 degrees every 60 minutes. The clockwork 56 rotationally drives the hour indicator drive wheel 52 at a rate such that the hour indicator wheel 60 is rotated 360 degrees every 12 hours. The hour indicator wheel 60 is configured such that it masks the clockwork 56 and the drive wheels from view. The minute indicator wheel 58 is configured so that the surface with the minute indicator is coplanar with the surface of the hour indicator wheel 60 with the hour indicator. The resulting effect is to give the unique appearance of floating rings, yet the time is interpreted using traditional clock interpretation means.
An additional embodiment is shown in FIG. 9 and FIG. 10. This embodiment is essentially the same as that shown in FIG. 7 and FIG. 8 with the addition of a demarcation frame 66. The demarcation frame 66 has the numerals 3, 6, 9, and 12 placed at their corresponding clock positions to aid the viewer in the determination of the indicated time. Alternately, all of the clock numerals 1 through 12, roman numerals, or other graphic indication could be used on the demarcation frame 66 to aid the viewer in the determination of the indicated time. The demarcation frame 66 is not a driven member and does not move. The clockwork 56 is attached to the demarcation frame 66. The demarcation frame 66 can be mounted on a wall or a frame.
An additional embodiment is shown in FIG. 11 and FIG. 12. This embodiment is essentially the same as that shown in FIG. 7 and FIG. 8 except that the hour indicator wheel 60 has been replaced with an hour indicator plate 68. The hour indicator plate 68 has an indicator that is smaller than the indicator on the minute indicator wheel 58 to denote the hour. The indicator can be either printed on, attached to, or machined into the hour indicator plate 68. The clockwork 56 rotationally drives the hour indicator drive wheel 52 at a rate such that the hour indicator plate 68 is rotated 360 degrees every 12 hours. The hour indicator plate 68 is configured such that it masks the clockwork 56 and the drive wheels from view. The resulting effect is to give the unique appearance of a floating time indication surface, yet the time is interpreted using traditional clock interpretation means.
An additional embodiment is shown in FIG. 13 and FIG. 14. This embodiment is comprised of the same demarcation ring 20, minute indicator ring 24, hour indicator ring 22, minute indicator drive wheel 26, and hour indicator drive wheel 28 as the preferred embodiment. However, in this embodiment the minute indicator ring 24 and hour indicator ring 22 are driven respectively by the minute indicator drive wheel 26 and hour indicator drive wheel 28 on the outside surface of the indicator rings 24 and 22. The outside drive clockwork 70 rotationally drives the minute indicator drive wheel 26 at a rate such that the minute indicator ring 24 is rotated 360 degrees every 60 minutes. The outside drive clockwork 70 rotationally drives the hour indicator drive wheel 28 at a rate such that the hour indicator ring 22 is rotated 360 degrees every 12 hours. The minute indicator ring 24 and hour indicator ring 22 are held against the drive wheels and idler wheels 74 by the force of gravity. The idler wheels 74 rotate freely about an axis through their centers. The demarcation ring 20 rests on the outside drive clockwork 70 body and an idler wheel 74 and is not driven.
The demarcation ring 20 has the numerals 3, 6, 9, and 12 placed at their corresponding clock positions to aid the viewer in the determination of the indicated time. Alternately, all of the clock numerals 1 through 12, roman numerals, or other graphic indication could be used on the demarcation ring 20 to aid the viewer in the determination of the indicated time. The demarcation ring 20 is not a driven member and does not move. The demarcation ring 20 rests on the body of the clockwork 30.
The minute indicator ring 24 and the hour indicator ring 22 are constructed of a clear material which allows for the demarcation ring 20 to be viewed through the minute indicator ring 24 and the hour indicator ring 22. The minute indicator ring 24 has an indicator to denote the minute of the hour. The indicator can be either printed on, attached to, or machined into the minute indicator ring 24. Likewise the hour indicator ring 22 also has an indicator, which is smaller than the indicator on the minute indicator ring 24 to denote the hour. The indicator can be either printed on, attached to, or machined into the hour indicator ring 22. The minute indicator drive wheel 26 and an hour indicator drive wheel 28 have small flanges which keep the minute indicator ring 24 and the hour indicator ring 22 properly aligned with respect to each other and the demarcation ring 20. The outside drive clockwork 70 and idler wheels 74 are mounted to a support frame 72 which in turn can be placed in a horizontal surface, such as a desk for use as a desk clock, or attached to a wall for use as a wall clock. The resulting effect is that the clock has a unique design that does not have the traditional clock hands, yet the time is interpreted using traditional clock interpretation means.
An additional embodiment is shown in FIG. 15 and FIG. 16. This embodiment is comprised of the same outside drive clockwork 70, support frame 72, idler wheels 74, minute indicator drive wheel 26, and hour indicator drive wheel 28 as the previous embodiment. In this embodiment the outside drive clockwork 70 rotationally drives the minute indicator drive wheel 26 at a rate such that an opaque minute indicator ring 76 is rotated 360 degrees every 60 minutes. The outside drive clockwork 70 rotationally drives the hour indicator drive wheel 28 at a rate such that an hour indicator disk 78 is rotated 360 degrees every 12 hours. The opaque minute indicator ring 76 and the hour indicator disk 78 are held against the drive wheels and idler wheels 74 by the force of gravity. The idler wheels 74 rotate freely about an axis through their centers.
The opaque minute indicator ring 76 has an indicator to denote the minute of the hour. The indicator can be either printed on, attached to, or machined into the opaque minute indicator ring 76. Likewise the hour indicator disk 78 also has an indicator, which is smaller than the indicator on the opaque minute indicator ring 76 to denote the hour. The indicator can be either printed on, attached to, or machined into the hour indicator disk 78. The minute indicator drive wheel 26 and an hour indicator drive wheel 28 have small flanges which keep the opaque minute indicator ring 76 and the hour indicator disk 78 properly aligned with respect to each other.
The hour indicator disk 78 is a flat circular disk of a width at its outer edge which allows it to ride within the flanges of the hour indicator drive wheel 28. The hour indicator disk 78 is wider in its center so that the surface of the hour indicator disk 78 with the indicator is coplanar with the surface which contains the indicator on the opaque minute indicator ring 76. The hour indicator disk 78 is symmetrical about an axis perpendicular to its rotational axis in order to ensure that the disk remains upright and well balanced when driven by the hour indicator drive wheel 28 and resting on idler wheel 74. The resulting effect is that the clock has a unique design that does not have the traditional clock hands, yet the time is interpreted using traditional clock interpretation means.
Thus the reader will see that the clocks of the invention provide unique designs which are easily read using traditional clock interpretation means. While my above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of preferred embodiments thereof. Many other variations are possible. For example, illumination of the rings of the preferred embodiment through the edges of said rings would add aesthetic appeal to the design and allow for time interpretation in low light situations.
Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
