2. Description of the Related Art In the case of a pointer-type timepiece, a time display portion provided on the front of a frame body is attached to a dial and a pointer shaft which penetrates the dial and protrudes forward and is attached to the front of the dial. The dial consists of a rotating hand (hour hand, minute hand and second hand) and a transparent cover covering the front surface of the hand. On this dial, numerals indicating the hour display characters 1 to 12 or scales and dots representing minute units are written. It is common. Further, as a clock used in traffic, for example, in the case of a clock installed in a station, the above-described normal time display characters 1 to 12 are used.
And the numbers 13 to 24 obtained by adding 12 to 1
Some are marked on one dial.

[0003]

The timepiece reads the time according to the position of the hands. However, in the case of using a general timepiece as described above to teach a child how to read the time, the hands are used. It is difficult to tell what time, minute, and second the position represents. Therefore, it is convenient if one frame can be replaced with a plurality of clock dials having several kinds of scale indications so that an infant can easily read the time. However, in the ordinary timepiece described above, the dial constituting the time display unit is fixed, and is not configured on the assumption that the dial is removed from the frame and replaced with another dial. If the dial is to be removed from the frame, it is necessary to first remove the transparent cover and the pointer, and such disassembly work is troublesome and difficult.
Further, when the dial is firmly adhered to the frame, the dial may not be removed from the frame unless the dial is damaged. Therefore, one dial is premised on one dial, and it is difficult to teach such a general clock how to read the time, especially to an infant. Therefore, it is conceivable to provide all the scale indications in units of hours, minutes and seconds on one dial, but there is a limit to providing a plurality of scale indications due to space limitations of one dial. In addition, the clock becomes difficult to read the time. Also, for diver watches, etc.,
A rotating bezel having a scale in units of minutes is provided on its front surface so as to surround the outer periphery of the time display unit (the dial). This rotating bezel is provided to make it easier for the user to see the elapsed time of diving and the like, but is not provided to make it easier to read the time. An object of the present invention is to make it easy to read the time by the position of the hands by making it possible to detachably attach another dial having a scale display different from a normal time display unit to the frame body, and particularly to make it easy to read the time. Another object of the present invention is to provide a pointer-type timepiece suitable for use as educational materials for infants.

[0004]

In order to achieve the above object, a pointer-type timepiece according to the present invention comprises a ring-shaped timepiece on a front surface of a frame so as to surround an outer periphery of a time display portion provided on the front of the frame. A mounting portion is formed, a ring-shaped dial is detachably provided on the ring-shaped mounting portion, and a scale display different from the scale display of the time display portion is provided on a front surface of the ring-shaped dial. Thea Ru. In the ring-shaped dial, one of a plurality of scale indications different from each other is attached to the ring-shaped attachment portion , or a plurality of scaled indications different from each other are attached to the ring-shaped attachment portion in a stacked state. Characterized by

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a clock face dial 2 having a front circular shape is fixed to the front surface of a concave portion of a frame 1 having a front circular shape. The clock dial 2 has twelve bar-shaped hour scales 2a. In the concave part on the back of the frame 1, the watch body 3
A pointer 4 consisting of a minute hand 4a and an hour hand 4b is attached to each end of a pointer shaft 3a projecting from the timepiece mechanical body 3 and penetrating the timepiece dial 2. A transparent protective cover 5 is attached in front of the pointer 4. Frame 1
Has an outer peripheral portion extending outward to surround the timepiece dial 2 in a wide ring shape, a portion (inner peripheral portion) 1a in contact with the outer periphery of the transparent cover 5 and an outermost peripheral portion (outer peripheral edge portion) of the frame 1. ) 1b each have the same height as the front surface of the transparent cover 5 (see FIG. 2 (b)), and the region 1c sandwiched between the two edges 1a, 1b is one level higher than the front surface of the transparent cover 5.
The area is a ring-shaped mounting portion 1c on which a ring-shaped dial described later is mounted.

As shown in FIGS. 2 and 3, at positions corresponding to 12:00, 4:00 and 8:00 on the ring-shaped mounting portion 1c, a rectangular through hole 1d and a partly semicircular through hole are respectively provided. 1
e, 1e are bored, and between the outer sides of the through holes 1d, 1e and the rising portion of the outer peripheral edge 1b of the frame, project from the outer periphery of a ring-shaped dial described later. Engaging portions 1f and 1g are formed for fitting and engaging certain engaging projections. 3
The through holes 1e, 1e, each of which has a semicircular shape, are formed in a size that allows a user's finger to be inserted.

As shown in FIGS. 2 (b) and 3, at positions corresponding to 12:00, 4:00 and 8:00 on the back surface of the frame 1, an inner periphery of a ring-shaped dial described later is engaged. A holding piece 1h for holding the lever on the back side of the frame body 1 is projected. FIG. 4 shows an example of the ring-shaped dial 6 attached to the ring-shaped mounting portion 1c of the frame 1 described above. A minute scale 6a in units of one minute is written on the front surface of the ring-shaped dial plate 6, and engagement protrusions 6b projecting in a rectangular shape are provided at positions corresponding to 12:00, 4:00, and 8:00 on the outer periphery. And an engagement projection 6c projecting in an arc shape is provided. These engagement projections 6b, 6c
The engagement portions 1e are formed at positions corresponding to 12:00, 4:00, and 8:00 of the ring-shaped mounting portion 1c, respectively (see FIG. 5). As described above, the engagement protrusions 6b,
When the ring 6c is engaged with the engaging portions 1f and 1g, the ring-shaped dial 6 is mounted on the ring-shaped mounting portion 1c, and the ring-shaped dial 6 itself cannot be rotated with respect to the frame 1. As shown in FIG. 4, since the shapes (sizes) of the engagement projections 6 b and 6 c protruding from the outer periphery of the ring-shaped dial 6 are changed, positioning can be performed, and the mounting position is incorrectly set. It is possible to prevent the ring-shaped dial plate 6 from being mounted on the ring-shaped mounting portion 1c. The ring-shaped dial 6
Is attached to the ring-shaped mounting portion 1c, the ring-shaped dial 6
Of the ring-shaped mounting portion 1c at 12:00, 4:00, and 8
Portions facing the through holes 1d and 1e drilled at occasionally corresponding positions are exposed on the rear surface of the frame 1.

When the ring-shaped dial plate 6 is mounted on the ring-shaped mounting portion 1c of the frame 1, the ring-shaped dial plate 6 is warped to a certain extent, and the engagement convex portions 6b, 6c, 6
c may be engaged with the engaging portions 1 f, 1 g, 1 g of the frame body 1 by pushing them respectively. As shown in FIG.
If the ring-shaped dial plate 6 having the minute scale 6a in units of minutes is mounted on the ring-shaped mounting portion 1c, it is easy to read the "minute" by the position of the minute hand 4a. Therefore, in the case of teaching the infant how to read the time, in FIG. 5, since the number on the minute scale 6a indicated by the minute hand 4a is "8", the current time is read as "8 minutes". Can be easily taught.

In addition to the one shown in FIG. 4, a plurality of ring-shaped dials 6 having different scales are prepared in advance, and one of them is mounted on the ring-shaped mounting portion 1c. ing. FIG. 6 shows an example of another ring-shaped dial 60. On the front face of the ring-shaped dial plate 60, hour scales 60a in units of hours are written in hiragana instead of numbers. The engagement projections 60b and 60c on the outer periphery are substantially the same as those shown in FIG. If this ring-shaped dial 60 is mounted on the ring-shaped mounting portion 1c,
Reading the "hour" by the position of the hour hand 4b becomes easier. Therefore, when teaching the infant how to read the time, for example, if the tip position of the hour hand 4b is between “10” and “11” of the hour scale 60a, the current time is “10”. You can easily teach that you read "time."

[0010] Of the plurality of ring-shaped dials, except for one attached to the ring-shaped mounting portion 1c, the remaining unused management is provided by protruding from the back surface of the frame 1. What is necessary is just to engage the inner periphery with a certain holding piece 1h and hold it. When removing the ring-shaped dial 6 from the ring-shaped mounting portion 1c of the frame 1, the through holes 1e,
1e, a finger is inserted, and the ring-shaped dial plate 6 is lifted so that the engagement protrusions 6c, 6c on the outer periphery thereof and the engagement portion 1 of the frame 1 are formed.
The engagement between the engaging protrusion 6b and the engaging portion 1f may be released by disengaging the engagement with the g and 1g and pulling the ring-shaped dial 6 from the front surface.

Although not shown, the ring-shaped mounting portion 1
c may be formed deep or the ring-shaped dial may be formed thinly, and may be mounted on the ring-shaped mounting portion 1c in a state where a plurality of ring-shaped dials having different scales are stacked. In such a configuration, the holding piece 1h protruding from the back surface of the frame 1 to hold a plurality of ring-shaped dials on the back surface becomes unnecessary. Although not shown,
The ring-shaped dial may be provided with different display scales on the front surface and the rear surface, respectively. In this case, twice as many variations can be provided as compared to the case where the display scale is provided only on one surface of the ring-shaped dial. In the above-described embodiment, the ring-shaped dial is attached to the ring-shaped mounting portion by projecting the engaging convex portion on the outer periphery of the ring-shaped dial and engaging the engaging convex portion with the engaging portion 1e. However, the present invention is not limited to this, and the ring-shaped dial may be attached to the ring-shaped mounting portion using, for example, a magnet system or a Velcro system. Furthermore, the number of engaging projections is not limited to three, and it is sufficient if at least two or more. Furthermore, the scale display provided on the front face of the ring-shaped dial is not limited to those shown in FIGS. 4 and 6, but also displays both the morning display and the afternoon display, and also displays the numbers and hiragana. May be used. Or, the normal display characters 1 to
Write the number from 13 to 24, which is 12 plus 12.
The hour may be read as "13:00". Furthermore, the ring attachment portion and the ring-shaped dial are not limited to the above-described circular shape (donut shape), but may be elliptical shapes or triangular shapes.
