Abstract

PURPOSE: To obtain a watch in which the face of the watch can be turned with respect to a strap through a simple structure by holding a spherical protrusion from casing in the socket means of a strap for receiving the protrusion while catching loosely. CONSTITUTION: The casing of a watch 1 has two different indicating faces 2, 3 which are made turnable so that they can be indicated alternately. For that purpose, attachment means 4-7 for fixing the casing to straps 8, 9 are provided. The means 4, 5 are, fitted removably to means 6, 7, i.e., spherical protrusions from the casing, formed as corresponding receiving sockets and riveted to the straps 8, 9. A slot 10 in the means 6, 7 has a wide part 11 for inserting the means 4, 5 and a narrow part 12 for preventing removal of the means 4, 5 and the means 4, 5 can move freely along the slot 10. Consequently, the watch can be fitted loosely over the wrist and can be turned to show any one face 2, 3.

Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD This invention relates to improvements in timing mechanisms, particularly watches.

For example, clocks with both analog and digital displays on the same device are widely (desired).An analog display often gives a broader sense of the time of day than a digital display, but a digital display More often used when making accurate time measurements.

[Prior art and problems with the invention]

To avoid the need for a double display on one side of the clock,
Sometimes it is desired to have a watch with different indications on each side. In this case, it must be possible to rotate the watch face during use. Utility Model No. 58-87510 and 59
No. 177325 discloses such a watch. However, in the configurations described in these publications, the timepiece has a normal strap attachment structure, and the strap has a complicated structure for rotating the timepiece as a whole. The aim of the invention is to provide a very simple arrangement which allows the watch face to be rotated relative to the strap. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a timepiece that can display two and more prongs separately.

[Means to solve the problem]

The timepiece according to the present invention has two surfaces with different indications arranged on both sides of the casing, and is provided with attachment means for attaching the casing to a strap or the like, so that one or the other of the two surfaces is displayed. the watch is rotatable relative to the strap or the like, the attachment means comprising a spherical projection extending from the casing along the stem and aligned with the axis of rotation thereof; The device is characterized in that it has socket means for loosely receiving the head-shaped projection, and the spherical projection is held within the socket means.

In embodiment B of the invention, a watch is provided in which the other display is a further time display. Preferably, the two different displays are an analog display and a digital display, or a stopwatch display.

Preferably, the attachment means comprises a bulbous projection and the receiving socket has a slot through which the stem of the bulbous projection passes but the bulbous head cannot pass. Furthermore, a ball-headed projection is attached to or part of the casing, and a receiving socket is attached to or part of the strap.

〔Example〕

The watch 1 has a first face 2 with an analog display and a second face 3 with a digital display. The casing of the watch 1 is provided with opposing attachment means 4, 5, which are used to rotatably attach the watch 1 to the corresponding attachment means 6.7 of the strap 8, 9. . The attachment means 4.5 are spherical projections from the casing, and the corresponding receptacles are removably fitted into attachment means 6.7 which are formed as receiving sockets. The attachment means 6.7 is formed as a socket and has a rivet (not shown).
It is attached to the strap 8.9 by.

The attachment means 6.7 each have a slot 10. Referring to FIGS. 2 and 3, the slot O has a wide portion 11 which is sufficiently wide to allow insertion of either of the spherical attachment means 4, 5. The slot 10 further has a narrowed portion 12, which has a spherical attachment means 4.
The stem of the attachment means 4.5 is narrow enough to prevent the slip-out of the attachment means 4.
It is designed to allow free movement along the

As shown in FIG. 6, in order to attach the watch 1 to the strap 8, the spherical attachment means 4 is inserted through the wide part 11 of the slot 10 into the attachment means 6, which is formed as a receiving socket. Then insert the stem of the spherical attachment means 4 into the slot 1.
0 into the narrow part 12 of the slot 100 until it reaches the end opposite the wide part 11 of the slot 100. By doing so, the axis of rotation of the watch is shifted approximately 90 degrees so that it extends in the plane of the strap 8. In the ball and socket configuration, the distance of the wide portion 11 from the end of the attachment means 6 is such that the length of the stem of the spherical attachment means 4 is such that the distance of the wide portion 11 from the end of the attachment means 6 is such that the length of the stem of the spherical attachment means 4 is the same as that of the wide portion 1.
This prevents it from falling without reaching 1. When the watch 1 is attached to the two straps 8, 9, the watch 1 can be worn on the wrist, and while worn on the wrist, either the first side 2 or the second side 3 of the watch 1 can be worn. can be rotated to show usually,
The watch is worn loosely and rotation of the watch 1 is not hindered by the wrist.

Another design for the attachment means 6, 7, which are designed as receiving sockets, is to provide a narrowing where the wide part 11 and the narrow part 12 of the slot 10 meet. This means pushing the stem of the spherical attachment means 4 into the stenosis with force, thereby reducing the possibility that the spherical attachment means 4 will fall out unexpectedly.

A further design for the attachment means 6, 7 formed as a receiving socket is to manufacture the attachment means 6, 7 as an integral part of the strap 8.9 as described above. Similarly, the spherical attachment means 4.5 can be manufactured integrally with the casing of the watch 1 or can be manufactured separately and fitted accordingly.

The timepieces and attachment means described above are not limited to use in wristwatches. The attachment means has the added advantage of being very easy to use, making it very easy to replace them on the same watch strap. Furthermore, such attachment means can also be used to attach the watch to other forms of support. Referring to FIG. 8, a clock is shown attached to a strap 13 for a hanging clock used on automobile dash boards or often found in sleeping cars.

Although the above description has been made with reference to a watch with an analogue display on one side and a digital display on the other side, this is not intended to limit the possibilities of what may be displayed on each side of the watch. A non-zero watch may have a digital display instead of an analog display on its first side and some other display on the opposite side. Such other display may be a stopwatch, or need not necessarily be a second time display, but may include a thermometer, barometer, heartbeat or pulse measuring device, etc. can.
