The invention relates to a device and method for simultaneously determining the time in at least two different time zones. More particularly, the invention relates to a device having at least a first clock and a second clock and a map of a geographical area depicting at least a first time zone and a second time zone, the first clock being positioned proximate to the first time zone and the second clock being positioned proximate to the second time zone; and a method of using the device to simultaneously determine the time in at least the first and second time zones.
Over-the-road truckers, airline personnel, and others who frequently travel between distant geographical areas often have a need to know the time in two or more time zones. This is typically achieved by a person calculating the time in a first time zone by determining the time in that zone and then adding or subtracting the number of hours to or from that time in accordance with how many time zones are between the first and second time zones. Because a mental calculation is involved in this method, it can be inconvenient, slow, and susceptible to human error.
Devices for automating this calculation have been developed to overcome the foregoing issues. For example, wristwatches that simultaneously display the time in more than one time zone are known. While these devices are convenient, they are less than optimal for travelers such as over-the-road truck drivers who move through more than two different time zones during a single trip. For such travelers, what is needed is a device that simultaneously displays the time in multiple time zones in such a manner that time in any of the multiple time zones can be determined with minimal mental effort. Such an easy-to-use device would be especially useful for travelers operating a motor vehicle, particularly over-the-road truck drivers who need to maintain their attention on the road.
The invention relates to the development of a device that allows a user to easily and readily determine the time in multiple time zones without requiring significant mental effort. The device is advantageous for motor vehicle operators who travel across multiple time zones and have a need to know the time in at least one of the time zones.
Accordingly, the invention features a device having mounted thereon both a plurality of clocks including at least a first and second clock, and a map of a geographical area depicting a plurality of time zones including at least the first and second time zones. In the device, the first clock is positioned proximate to the first time zone and the second clock is positioned proximate to the second time zone.
In one variation, the first clock is positioned on the device directly above the first time zone and the second clock is positioned on the device directly above the second time zone. In another variation, the first clock is positioned on the device directly below the first time zone and the second clock is positioned on the device directly below the second time zone.
In the device, the geographical area can include the continental 48 states of the United States of America, the plurality of clocks mounted on the device can further include at least a third clock and a fourth clock; and the plurality of time zones can include four time zones: the Pacific time zone, the Mountain time zone, the Central time zone, and the Eastern time zone.
In one embodiment of the device, the first clock is mounted to the device within a first clock mounting area of the device and the second clock is mounted to the device within a second clock mounting area of the device, and the first time zone, the first clock mounting area, and/or the first clock are marked with a first discernible identifier and the second time zone, second clock mounting area and/or the second clock are marked with a second discernible identifier differing from the first discernible identifier. The discernible identifiers might be shades, colors, and/or alphanumeric characters.
The device might also include a front portion including the plurality of clocks and the map of the geographical area; and a back portion including a fastener (e.g., an adhesive, a mechanical connector, and a hook and loop type connector) for affixing the device to the dashboard of a motor vehicle.
In some variations, the device further includes a base portion (e.g., including a non-slip material) for supporting the device on a horizontal surface such as a desktop.
The front portion can be substantially planar or non-planar, and at least one of the plurality of clocks might be analog, digital, reversibly removable from the device, and/or battery-operated.
In another aspect, the invention features a device for simultaneously displaying the time in at least a first time zone, a second time zone, a third time zone, and a fourth time zone. This device includes a plurality of clocks mounted on the device, the plurality of clocks including at least a first clock, a second clock, a third clock and a fourth clock; and a map including the continental 48 states of the United States of America mounted on the device, the map depicting a plurality of time zones, the plurality of time zones including at least the first time zone, the second time zone, the third time zone, and the fourth time zone. In this device, the first clock is positioned proximate to the first time zone, the second clock is positioned proximate to the second time zone, the third clock is positioned proximate to the third time zone, and the fourth clock is positioned proximate to the fourth time zone, and the first time zone is the Pacific time zone, the second time zone is the Mountain time zone, the third time zone is the Central time zone, and the fourth time zone is the Eastern time zone.
The invention further features a method for determining the time in a different time zone. The method includes the steps of:(a) providing a device in a first time zone, the device including a plurality of clocks mounted on the device, the plurality of clocks including at least a first clock and a second clock; and a map of a geographical area mounted on the device, the map depicting a plurality of time zones, the plurality of time zones including at least the first time zone and a second time zone, wherein the first clock is positioned proximate to the first time zone and the second clock is positioned proximate to the second time zone; and (b) determining the time on the second clock.

The invention encompasses various devices and methods that facilitate determining the time in a particular time zone among a multitude of contiguous time zones. The below described preferred embodiments illustrate adaptations of these devices and methods. Nonetheless, from the description of these embodiments, other aspects of the invention can be made and/or practiced based on the description provided below.
Referring to
The front portion 16 features four clock mounting areas 14a-d into which four clocks 12a-d are placed. The clocks 12a-d shown are battery-operated, round, analog clocks, but might take the form of any suitable time display device, e.g., a clock with a digital (LED, LCD) display. Also on the housing 11 is a map of a geographical area 20. In the embodiment shown, the map 20 is of the continental United States that depicts its four time zones 22a-d. Each of the clocks 12 is positioned proximate to the corresponding time zones 22.
