Description

Standard, world combined use clock using ring (ring) gear

1 is an exploded perspective view of the whole.

2 is a structural diagram of a longitudinal section.

The present invention arranges an electric gear for acceleration for 24 hours in the hour hand rotating gear, which is a 12-hour rotation period in a watch movement, and the front end of the electric gear penetrates one side of the no-bearing front surface. The ring-shaped gears interlocked with each other rotate in a 24-hour cycle, so that the clocks of the world's time can be read by the 24-hour rotating plate which rotates simultaneously with the usual instructions and the function of a normal clock by a 12-hour dial. It is time, 24-hour clock.

For the reading of the world time, the simultaneous display of 24 hours should be the entire time. Conventional clocks generally use the 12: 1 deceleration ratio between the minute and hour hands in the rotating gear of the clock connected to the second, minute and hour hands. By changing the rotation period of the gear corresponding to the hour hand to a 24-hour period, the method of reading and reading the names of countries around the world was taken. However, this is a 24-hour read-only. The user has caused confusion in reading local time, and has had the discontinuity of using a common clock for reading local time with relatively high frequency of use. In another example, 24 hours of the same type besides normal seconds, minutes, and hour hand The rotating rod is double-exposured on the outside of the rotating rod for hour hand rotation, and during normal 12 hours, the rotating plate is rotated simultaneously with the minute hand on the same central axis. The function of the key is 12 hours and 24 hours of indication function, but 12 and 24 hours should be doubled on the same letter board and 12 and 24 hours of instructions are overlapped on the central axis. There was a confusion because of the complexity of reading the supporting angles of the guidelines.

The present invention eliminates the above problems, and the known hour, minute hand and 12 hour dials rotate in a known manner and read the local time, and the 24-hour rotating plate rotates from the back of the 12 hour dial and the outside of the 12 hour problem farm. It is to facilitate the separate reading of 12 hours and 24 hours by the contrast reading of the names of the countries shown in the circumference at a certain interval as described in detail by the drawings as follows.

That is, the dial 5 of the present invention has a central 12-hour display portion 5 ', the outer portion of which is a circular transparent portion 5 ", and a triangular visual indication and the names of the countries 5 " Is shown.

In addition, the round 24-hour rotating plate 4 disposed on the back thereof is a thin plate, and the circumference is marked with a 24-hour mark separated by day and night as color brown, and a fixing pin 4 'is protruded on the back of the ring-shaped gear 3 and The ring-shaped gear 3 has a hollow inside whose inner diameter is larger than the outer diameter of the middle part of the fixing bolt 6, and is rotated around the fixing bolt 6 as a central axis. The toothed end of the ring-shaped tooth 3 engages and interlocks the electric gear through hole 1 'of the movement 1 with the tip 2' of the protruding electric gear 2, but the electric gear 2 is well known. By interlocking with the small pinion (10) formed separately in the rotating gear (10) to decelerate in a rotation period of 24 hours, the coupling state of the upper portion of the fixing bolt (6) as shown in Figure 2 Move through the dial (5), the 24-hour rotating plate (4), and the hollow of the ring gear (3) Each of the guide rods which are engaged and fixed to a well-known nut (NUT) formed on the rotary bar protrusion 1 "of the bolt 1, and protrudes to the front of the character board 5 through the inner hole of the fixing bolt, respectively. Known hour hand 7, minute hand 8, and second hand 9 are inserted and used. Reference numeral 12 denotes a reduction gear of known minute hand-hour hand, and 13 is also a known minute hand turning gear.

In the present invention, the 24-hour rotating plate 4 and the ring-shaped tooth 3 are rotated about the middle of the fixing bolt 6, and the 24-hour rotating plate 4 and the ring-shaped tooth 3 are hollow ( The inner diameter of the hollow should be greater than or equal to the outer diameter of the middle of the fixing bolt 6, and in this case, a considerable safety is given to the rotation of the 24-hour rotating plate 4, which is inevitably larger in diameter than a relatively small watch movement.

Effects of the present invention configured as described above are as follows.

That is, when the movement 1 is driven to operate with the minute hand, minute hand, and hour hand rotating gears, the instructions 7, 8, and 9 inserted at each end of the rotating rod rotate, and the 12-hour display part 5 ′ of the character board 5 is rotated. In contrast to the conventional 12-hour clock function is performed, while the electric gear (2) interlocked with the hour hand turning gear (10), the front end of the movement (2) of the front end of the movement (1) ring type Rotate the gear (3), but the reduction of 1/2 of the rotation period is made by the electric gear (2) and the ring-shaped gear (3) described above. The integrated rotating plate 4 also makes the same rotation, allowing the time display on the outer circumference to be projected through the circular transparent portion 5 "of the dial 5 and again displaying the clock angle name display shown at regular intervals on the outer circumference (5). In contrast to "), the current time of the world is read.

As described above, the present invention enables a 24-hour display function without damaging the movement's unique 12-hour indication function as a simple means added to a normal watch movement, and uses a ring-shaped gear with a relatively large 24-hour rotating plate. In addition, the fixed bolt, which was used only as a simple coupling means, is rotated to its center axis, which enables stable rotation. It is devised to provide a very beneficial and convenient, without causing.

Claims (1)

As shown, a circular plate (24) is shown in which a ring-shaped tooth (2) having an inner hole which allows the upper end (2 ') of the electric gear to protrude to one side of the known movement (1) and penetrates the fixing bolt (6) ( 4) Integrate with one fixing pin (4 ') and make it interlock with the upper end (2') of the major gear, rotate once every 24 hours, and the letter board (5 ') for 12 hours in the center, and the ring-shaped transparent part (5) A standard, world-wide watch using a ring-shaped gear combined with a letter board (5) where a place name is shown at the edge of ").
