## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to timepieces, and particularly to an adjustable global timepiece.
2. Description of Prior Art
A traditional timepiece generally includes a case, a dial, a movement mechanism, and time pointers, i.e. a hour hand, a minute hand and a second hand. Such timepiece can only display the time in a local time zone and cannot instantly display the time in another time zone. However, for those people frequently traveling around the world, it becomes more and more important to understand and master the local time in different time zones. Under this kind of demand, the common timepiece will not be able to provide this kind of information. Gradually, various kinds of global timepiece have been developed to improve this inconvenient situation, which can show the local time all over the world through the reading of a single timepiece.
China patent application serial No. 03215040.7 discloses a global timepiece. The global timepiece includes a dial assembly, a movement mechanism, and a date memory. The dial assembly includes a time dial and a time zone dial. The movement mechanism has a main shaft. The main shaft extends through the time dial and engages with the time zone dial so as to drive the time zone to rotate. However, the global timepiece is unduly complex, compared with a traditional timepiece. It is difficult for a user to directly understand and master the time through a glance.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an adjustable global timepiece, which has a simple structure, and is easy and convenient for operation.
In order to achieve the above-mentioned object, an adjustable global timepiece is provided. The adjustable global timepiece includes a minute pointer, a hour pointer, a movement mechanism, an inner time dial, a time zone dial and an outer time dial. The movement mechanism has a shaft. The inner time dial has 24 equally divided labeled blocks configured for displaying a first time in a first time zone. The inner dial is coupled to the shaft so as to be driven by the movement mechanism. The time zone dial has 24 equally divided labeled blocks. The time zone dial is manually adjustably rotatable relative to the shaft. The outer time dial has 24 equally divided labeled blocks configured for displaying a second time in a second time zone. The outer time dial has a time zone pointer located at the location of 24 o'clock thereof configured for indicating the second time zone. The outer time dial is manually adjustably rotatable relative to the shaft.
In another aspect of the present invention, an alternative adjustable global timepiece is provided. The adjustable global timepiece includes a minute pointer, a hour pointer, a movement mechanism, an inner time dial, a time zone dial and an outer time dial. The movement mechanism has a shaft. The inner time dial has 12 equally divided labeled blocks configured for displaying a first time in a first time zone. The inner dial is coupled to the shaft so as to be driven by the movement mechanism. The time zone dial has 12 equally divided labeled blocks. The time zone dial is manually adjustably rotatable relative to the shaft. The outer time dial has 12 equally divided labeled blocks configured for displaying a second time in a second time zone. The outer time dial has a time zone pointer located at the location of 12 o'clock thereof configured for indicating the second time zone. The outer time dial is manually adjustably rotatable relative to the shaft.
The adjustable global timepiece may further includes a mounting base with the inner time dial, the time zone dial, and the outer time dial being mounted thereon. Correspondingly, the mounting base has 12 or 24 equipage first indentations, 12 or 24 resilient members and 12 or 24 beads. The resilient members and beads are received in the corresponding first indentations. The outer time dial has a lower surface with 12 or 24 equipage second indentations defined therein for partially receiving the beads. The second indentations spatially correspond to the 12 or 24 equally divided labeled blocks of the outer time dial and the first indentations.
The outer time dial may advantageously have a peripheral portion raised relative to the mounting base for facilitating manually rotation thereof. The time zone dial may include a knob configured for facilitating manually rotation thereof. Alternatively, the adjustable global timepiece may further includes a gear mechanism configured for facilitating manually rotation of the time zone dial. The gear mechanism includes a linkage shaft having a first end and an opposite second end, a gear arranged at the first end, and a wind knob arranged at the second end. The gear is meshed with the time zone dial.
Compared with conventional global timepiece, the present global timepiece has the following advantages. Firstly, the global timepiece may employ driving means of a traditional timepiece, e.g. a clockwork, a movement mechanism, and so on. By simply modification of the traditional timepiece to further provide a time zone dial and an outer time dial, the global timepiece can thus display time in two global time zones by adjusting the relative position of the time zone dial, the outer time dial, and the inner time dial. Secondly, the time zone dial and the outer time dial may be manually operated without the need for extra driving mechanisms.
The above and other features of the invention, including various novel details of construction and combination of parts, will now be more particularly described with reference to the accompanying drawings, in which:

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Reference will now be made to the drawings to describe the present invention in detail.
Referring to FIG. 1, this shows an adjustable global timepiece in accordance with a first preferred embodiment. The adjustable global timepiece beneficially includes an inner time dial 2, a time zone dial 3 and an outer time dial 4. The inner time dial 2 has 24 equally divided labeled blocks configured for displaying a first time in a first time zone. In the present embodiment, the adjustable global timepiece further includes a movement mechanism, a second pointer, minute pointer, a hour pointer, each of which may be replaced with a conventional configuration of a tradition timepiece. The movement mechanism has a shaft. The inner time dial 2 is coupled to the shaft so as to be driven by the movement mechanism. The time zone dial 3 has 24 equally divided labeled blocks. The time zone dial 3 is configured to be manually adjustably rotatable relative to the shaft. The outer time dial 4 has 24 equally divided labeled blocks configured for displaying a second time in a second time zone. The outer time dial 4 has a time zone pointer 13 located at the location of 24 o'clock thereof configured for indicating the second time zone. The outer time dial 4 is configured to be manually adjustably rotatable relative to the shaft.
In the illustrate exemplary embodiment, the 24 equally divided labeled blocks of the inner time dial 2 and outer time dial 4 correspond to 1 though 24 o'clock of a whole day, respectively. The 24 equally divided labeled blocks of the outer time dial 4 correspond to the 24 time zones, i.e. ZERO time zone, WEST 1 though WEST 12 (EAST 12), and EAST 12 though EAST 1, in a clockwise order.
In use, firstly, the time pointers, the inner time dial 2 and the time zone dial 3 are set to indicate the time in the first time zone. As shown in FIG. 1, in the present embodiment, the first time zone is EAST 8, the time zone dial is therefore adjusted such that the block of the time zone dial 3 that is labeled with EAST 8 is set to the location of 24 o'clock of the inner time dial 2. In addition, the time in the EAST 8 time zone is 7:48:38, the time pointers are then set with respect to the inner time dial 2 to indicate 7:48:38. Secondly, the outer time dial 4 is adjusted such that the time zone pointer 13 thereof points at the block of the time zone dial 3 that shows the second time zone, e.g. EAST 1 time zone, in the illustrated embodiment. As a result, the time that is indicated by the time pointers with respect to the outer time dial 4 is the time in the second time zone, i.e. 0:45:38 in EAST 1 time zone.
Referring to FIG. 2, this shows an adjustable global timepiece in accordance with a second preferred embodiment. The adjustable global timepiece beneficially includes an inner time dial 2, a time zone dial 3 and an outer time dial 4. The inner time dial 2 has 12 equally divided labeled blocks configured for displaying a first time in a first time zone. In the present embodiment, the adjustable global timepiece further includes a movement mechanism, a second pointer, minute pointer, a hour pointer, each of which may be replaced with a conventional configuration of a tradition timepiece. The movement mechanism has a shaft. The inner time dial 2 is coupled to the shaft so as to be driven by the movement mechanism. The time zone dial 3 has 12 equally divided labeled blocks. The time zone dial 3 is configured to be manually adjustably rotatable relative to the shaft. The outer time dial 4 has 12 equally divided labeled blocks configured for displaying a second time in a second time zone. The outer time dial 4 has a time zone pointer 13 located at the location of 12 o'clock thereof configured for indicating the second time zone. The outer time dial 4 is configured to be manually adjustably rotatable relative to the shaft.
In the illustrate exemplary embodiment, the 12 equally divided labeled blocks of the inner time dial 2 and outer time dial 4 correspond to 1 though 12 o'clock of a half day, respectively. As is known, the time differences between EAST 1 and WEST 11, EAST 2 and WEST 10, EAST 3 and WEST 9, . . . EAST 12 and WEST 12, are all 12 hours. Therefore, the 12 equally divided blocks of the outer time dial 4 are labeled to indicate the foregoing 12 pairs of time zones, i.e. EAST 1 and WEST 11, EAST 2 and WEST 10, EAST 3 and WEST 9, . . . EAST 12 and WEST 12.
In use, firstly, the time pointers, the inner time dial 2 and the time zone dial 3 are set to indicate the time in the first time zone. As shown in FIG. 1, in the present embodiment, the first time zone is EAST 8, the time zone dial is therefore adjusted such that the block of the time zone dial 3 that is labeled with EAST 8 is set to the location of 12 o'clock of the inner time dial 2. In addition, the time in the EAST 8 time zone is 3:45:38, the time pointers are then set with respect to the inner time dial 2 to indicate 7:48:38. Secondly, the outer time dial 4 is adjusted such that the time zone pointer 13 thereof points at the block of the time zone dial 3 that shows the second time zone, e.g. EAST 11 time zone, in the illustrated embodiment. As a result, the time that is indicated by the time pointers with respect to the outer time dial 4 is the time in the second time zone, i.e. 6:45:38 in EAST 11 time zone. Understandably, due to the time difference between the EAST 11 and WEST 1 is 12 hours, the time in the WEST 1 time zone is thus 18:45:38.
Referring to FIG. 3, this shows an adjustable global timepiece in accordance with a third preferred embodiment. The adjustable global timepiece beneficially includes a movement mechanism, an inner time dial 2, a time zone dial 3 and an outer time dial 4. The movement mechanism has a shaft.
