Description

The present invention relates to a watch.

In general, a timepiece allows a user to visually recognize a time display from a relative position between an hour letter and a pointer on a dial through a windshield (see Patent Document 1). Some watches are provided with a dial ring arranged so as to surround the dial, and some clocks are provided with a counter ring for hour letters (see Patent Document 2).

JP-A-2009-63490 JP-A-2015-137884

The dial ring is located radially outside the dial, so if the user is not facing the watch, that is, if the watch is viewed from a direction that is not up or down (approximately perpendicular to the dial). Higher visibility than the dial. That is, the visibility of the time display can be improved by providing the hour character on the return ring.

However, for example, when the user wants to check the current time, the clock may be viewed from the side, that is, a direction orthogonal to the vertical direction or almost from the side, depending on the positional relationship between the clock and the user. In this case, there is a problem that the visibility is not sufficient because the visible time character area is remarkably smaller than that when viewed from the front.

The present invention has been made in view of the above, and an object of the present invention is to propose a timepiece that can improve the visibility of the time display when the user does not face the timepiece.

In order to solve the above-mentioned problems and achieve the object, the clock in the present embodiment covers a body having an opening, one of the openings, a windshield fixed to the body, and the other of the openings. A back cover fixed to the body, a facing ring that can be visually recognized from the outside through the windshield, and one or more hour letters provided on the facing ring and facing the windshield in the vertical direction. The facing ring is provided with an inclined portion that is inclined outward in the radial direction from an upward side to a downward side in the vertical direction, and the hour character is provided on the inclined portion. ..

The timepiece of the present invention has the effect of improving the visibility of the time display when the user does not face the timepiece.

The oscillator is a source for measuring the time displayed on the clock 1 and generating a reference frequency related to other functional operations, and for example, a crystal oscillator can be used. Since the oscillation characteristics of the crystal oscillator tend to fluctuate depending on the external temperature, a temperature-compensated crystal oscillator (TCXO) may be used.
The control circuit is a circuit that controls the clock 1, measures the internal time of the clock 1 based on the clock signal output from the oscillator, and outputs control signals according to each function. The control circuit is composed of a circuit including a CPU (Central Processing Unit) and a memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory).

The drive mechanism includes a drive circuit, a motor, a train wheel gear, and the like, and a control signal from the control circuit is input to the drive circuit, and the motor is driven according to the input signal. The train wheel gears connected to the motor move in cooperation. For example, when a pointer is attached to one end of the train wheel gear, the pointer can be rotationally driven. In the present embodiment, as the motor, a step motor (not shown) and an electret motor (hereinafter, may be referred to as “EM”) 85 are arranged. Details of EM85 will be described later.

The power generation mechanism generates power from external energy and supplies the generated power to electronic components such as secondary batteries and control circuits. As the power generation mechanism, a photoelectric conversion element that converts light energy, a thermoelectric conversion element that converts thermal energy, a mechanical electric conversion element that generates power from mechanical motion such as vibration energy, and the like can be used. In this embodiment, two electret generators (hereinafter, may be referred to as “EG”) 81 and 82, which are mechanical electric conversion elements, are used as the power generation mechanism. Details of EG81 and 82 will be described later.
The secondary battery is a power source that can store the electric power generated by the power generation mechanism and also supplies the control circuit, the drive mechanism, and other electronic components. As the secondary battery, for example, a lithium ion battery or an all-solid-state battery can be used.

Here, the electret motor (EM85) and the electret generator (EG81, 82) used in the drive mechanism and the power generation mechanism of the present embodiment will be described. Both EM85 and EG81, 82 are electrostatic induction type mechanical electric conversion elements. The electrostatic induction type mechanical electric conversion element is composed of, for example, a mover formed with a plurality of charged electrodes and a stator formed with a plurality of counter electrodes arranged so as to face the charged electrode, and moves. The relative movement of the child and the stator allows for electrical-mechanical conversion.
In the present embodiment, the mover has a substantially disk shape and is a rotor that rotates about a rotation axis. A gear is attached to the rotating shaft of the mover, and is connected to a train wheel gear (not shown). The stator is a substrate on which an electrode of a rotor and a plurality of electrodes having a substantially body shape are formed, and a resin substrate or a glass substrate can be used as the substrate.

When an electrostatic induction type mechanical electric conversion element is used as an electlet motor, for example, the rotor is rotated by inputting a signal from a drive circuit that applies different potentials to adjacent electrodes among a plurality of fixed electrodes. Can be driven. In order to rotate continuously, the potential applied to the fixed electrode may be switched over time. The rotation speed depends on the signal switching interval (frequency).
When the electrostatic induction type mechanical electric conversion element is used as an electret generator, for example, a rotary weight (not shown) is connected to the train wheel gear. The rotary weight is configured to be freely rotatable around a rotation axis as the posture of the clock 1 changes, and the rotation of the rotary weight causes the rotor via the train wheel gear to rotate. As a result, a potential difference is generated between the adjacent electrodes among the plurality of fixed electrodes, so that power can be generated.
The EM85 and EG81, 82 of the present embodiment have a configuration in which a stator arranged at least on the upward side forms a plurality of transparent conductive films on a transparent substrate, and when incorporated into the watch 1, the user Is arranged on the upper side of the movement 8 so that the movement 8 can be visually recognized.

A drive mechanism, a power generation mechanism, and the like are attached to the main plate 83. The presser plate 84 rotatably supports each train wheel gear arranged between the pressing plate 84 and each plate 83.

The clock display unit 3 has a pointer 33, a dial 34, and a dial ring 31. The clock display unit 3 displays the internal time measured by the control circuit of the movement 8 and displays functions related to other functions.

The pointer 33 is arranged so as to be rotatable around the center O of the clock 1, is connected to the train wheel gear of the movement 8, and is driven to rotate via a motor that is driven in response to a drive signal of the drive circuit. To do. The pointer 33 has a rod shape and is formed of a metal material, a resin material, or the like.
In the present embodiment, the pointer 33 is the second hand 33A, the minute hand 33B, and the hour hand 33C, and is arranged on the upper side (windshield 4 side) of the upper opening 21a of the body 2. Depending on the position pointed to by the pointer 33, the current time based on the internal time can be displayed, and if it has other functions, setting information corresponding to the function can be displayed. Information display of other functions includes ON / OFF setting of the alarm function, alarm setting time, chronograph display, remaining battery level, and the like.

The dial 34 is arranged between the pointer 33 and the movement 8 to protect the movement 8.
The return ring 31 is arranged along the circumferential direction of the rotating surface of the pointer 33. Hourji 32 (hours 32A, 32B) are provided on the surface of the return ring 31 (the side facing the windshield 4). That is, the hour character 32 is arranged so as to face the windshield 4 in the vertical direction, and can be visually recognized by the user through the windshield 4. The user can recognize the current time, function setting information, and the like by the relative positions of the pointer 33 (second hand 33A, minute hand 33B, and hour hand 33C) and the hour character 32.

The return ring 31 has an inclined portion 312 that is inclined outward in the radial direction from the upward side to the downward side in the vertical direction. The hour character 32 is formed on the inclined portion 312. As a result, when the user does not face the clock 1, it is possible to suppress an increase or decrease as compared with the case where the visible area of the hour character 32 faces the clock 1, so that each hand for the hour character 32 can be suppressed. It becomes easier for the user to confirm the relative positions of 33A to 33C. Therefore, it is possible to improve the visibility of the time display when the user does not face the clock 1.

In the present embodiment, as shown in FIG. 3, the return ring 31 is arranged on the return receiving portion 29 formed on the body 2. The inner circumference of the return receiving portion 29 corresponds to the above-mentioned upward side opening 21a, and the return ring 31 is configured to surround the upward side opening 21a. Further, the return ring 31 has a flat portion 311 and an inclined portion 312 and a tip portion 313 from the outside to the inside in the radial direction, and the facing receiving portion 29 has a flat portion 311 and an inclined portion 312 and a tip portion 313. It has a corresponding flat portion 24, a corresponding inclined portion 25, and a corresponding tip portion 26 so as to correspond to each portion of the above.

The flat end portion 311 is located on the outer side of the return ring 31 in the radial direction, and is located on the back cover 5 side of the inclined portion 312 and the tip portion 313 when viewed from the vertical direction. Further, when viewed from the vertical direction, the downward side end surface 311a is formed as a flat surface. The corresponding flat portion 24 corresponding to the flat end portion 311 has an upward side end surface 24a which is a flat surface corresponding to the downward side end surface 311a of the flat end portion 311 on which the flat end portion 311 is placed.
The inclined portion 312 is located at the central portion in the radial direction of the return ring 31. The inclined portion 312 is inclined outward in the radial direction from the upward side to the downward side, and the upward side end surface 312a is formed as an inclined surface. That is, the upward side end surface 312a is formed in the direction between the upward direction and the radial outer direction. The upper end surface 312a in the present embodiment is formed of an annular flat surface, but may be a curved surface such as a curved surface, or a composite surface obtained by combining a curved surface and a flat surface. Similar to the inclined portion 312, the corresponding inclined portion 25 corresponding to the inclined portion 312 is formed so as to be inclined inward in the radial direction from the downward side to the upward side in the vertical direction, and the inclined portion 312 is mounted on the inclined portion 312. Be placed.
The tip portion 313 is located at the inner end portion in the radial direction of the return ring 31, is formed so as to project inward from the inclined portion 312, and is upward side from the flat end portion 311 when viewed from the vertical direction. Is located in. The corresponding tip portion 26 corresponding to the tip portion 313 is formed so as to project from the radial inside of the corresponding inclined portion 25 in the radial inward direction, and the tip portion 313 is placed therein.

The flat end portion 311 of the return ring 31 has a boss 314 formed so as to project downward, and the corresponding flat end portion 24 of the return receiving portion 29 is above the flat end portion 24 corresponding to a position corresponding to the boss 314. It has a boss hole 27 formed by being recessed downward from the directional end surface 24a. By inserting the boss 314 into the boss hole 27, the position of the return ring 31 on the body 2 (clock 1) can be determined and can be easily fixed.
When viewed from the vertical direction, one or a plurality of bosses 314 are formed with respect to the circumferential direction of the return ring 31, and at least a number corresponding to the boss 314 is formed in the circumferential direction of the return receiving portion 29. ing.

In the present embodiment, the return ring 31 has a flat end portion 311 and a tip portion 313 on the outside and the inside of the inclined portion 312 in the radial direction, respectively, but the present invention is not limited to this. Either one or both of the flat end 311 and the tip 313 may be omitted. Further, the boss 314 of the return ring is formed at the flat end portion 311 but is not limited to this, and may be formed at the inclined portion 312 or the tip portion 313, and the boss hole 27 also corresponds to the position of the boss 314. It may be formed on the corresponding inclined portion 25 or the corresponding tip portion 26, and is preferably provided arbitrarily according to the shape of the return ring 31.
Further, the return ring 31 is not limited to being arranged in the return receiving portion 29 of the body 2, and the return ring 31 may be arranged directly on the dial 34 by providing a boss hole 27 in the dial 34. A boss hole 27 may be provided in a movement receiving member (not shown) of the movement 8 to arrange the return ring 31.
Further, the fixing of the return ring 31 is not limited to the combination of the boss 314 and the boss hole 27, and the return ring 31 and the receiving member may be adhesively fixed by using an adhesive.

Here, it is preferable that at least a part of the inclined portion 312 of the return ring 31 protrudes upward from the upward end portion of the body 2 with respect to the upward side surface or end portion in the vertical direction. ..
In the present embodiment, as shown in FIGS. 2 and 3, the body 2 has an annular outer wall portion 23 on the outer peripheral portion on the upper side in the vertical direction and on the outer side in the radial direction. In other words, the outer wall portion 23 is formed so as to project upward from the radial outside of the corresponding flat portion 24. The outer wall portion 23 functions as a positioning and fixing member for inserting, positioning and fixing the windshield 4 with the waterproof member 6 interposed therebetween. Then, an annular accommodation space portion S2 surrounded by the outer wall portion 23 and the return receiving portion 29 is formed. That is, it can be said that the windshield 4, the waterproof member 6, the dial ring 31 and the hour character 32, which are a part of the clock display unit 3, are arranged in the accommodation space portion S2.

The upper surface or end of the body 2 in the present embodiment corresponds to the upper end of the outer wall 23, and is located on the uppermost side of the body 2. Then, a part of the inclined portion 312 and the tip portion 313 of the return ring 31 are located above the upward end portion of the outer wall portion 23 in the vertical direction. As a result, it is possible to prevent the inclined portion 312 of the return ring 31 from being hidden by the outer wall portion 23, so that the visibility of the time display, the function display, and the like can be further improved.

The hour character 32 is an index for the user to recognize the information regarding the position of the pointer 33, and is fixed to the inclined portion 312 of the return ring 31. The hour character 32 may be printed on the surface of the facing ring 31, may be formed integrally with the facing ring 31, or may be formed separately. When the hour character 32 is formed separately, it is fixed to the dial ring 31 with an adhesive, a boss and a boss hole, or the like. Hereinafter, an example will be described in which a decorative member formed as a separate body is adhesively fixed as an hour letter 32. A plurality of hour characters 32 are arranged along the circumferential direction of the return ring 31. The shape of the hour letter 32 may be different. In the present embodiment, as shown in FIG. 1, two types of hour letters 32A and 32B are regularly arranged. The hour characters 32A are formed at equal intervals of, for example, 12 o'clock in the circumferential direction of the return ring 31 at every 30 degrees. That is, each hour character 32A corresponds to 1 o'clock to 12 o'clock, respectively. The hour letters 32B are formed at equal intervals of 5 degrees between adjacent hour letters 32A in the circumferential direction of the return ring 31. The hour characters 32A and the hour characters 32B correspond to "minutes" and "seconds" in the time information. The hour character 32 can be used alone or in combination with the pointer 33 in order to display the status confirmation of the function of the clock 1 and to display the information caused by the function.

In the vertical direction, at least a part of the hour character 32A is formed so as to project radially inward of the inclined portion 312 or upward from the tip portion 314. In other words, a part of the hour character 32A projects upward from the upward end of the return ring 31 in the vertical direction. As a result, when the user looks at the clock display unit from a direction that does not face the clock 1, the hour character located on the side opposite to the user's viewing side can also be visually recognized. Therefore, the visibility of the time display, the function display, and the like can be further improved.
Further, since the distance between the pointer 33 and the hour character 32 in the vertical direction can be shortened, it becomes easier for the user to confirm the relative position of the pointer 33 with respect to the hour character 32.
In the present embodiment, an example in which each of the hour characters 32A protrudes upward from the upward end of the return ring 31 has been described, but at least one of the plurality of hour characters 32A has been described. Only one may protrude upward. For example, if the configuration is such that only the hour character 32A arranged at the 12 o'clock position protrudes, it becomes easier for the user to recognize the viewing direction. Similarly, the hour character 32A at four locations in the 3 o'clock, 6 o'clock, 9 o'clock, and 12 o'clock directions may be configured to protrude. Further, the hour character 32B may also have a configuration that protrudes upward from the return ring 31 in the same manner as the hour character 32A.

The hour character 32A is formed so that at least a part of the hour character 32A projects upward from the outer wall portion 23 of the body 2 described above in the vertical direction. In other words, a part of the hour character 32A projects upward from the upward end of the body 2 in the vertical direction. As a result, the hour character 32A is hidden by the outer wall portion 23 even when the user views the clock display unit 3 from a direction different from the facing direction, particularly from a direction close to the horizontal plane (XY plane) orthogonal to the vertical direction. It can be visually recognized without being affected. Therefore, it is possible to prevent the hour character 32 from being hidden by the outer wall portion 23, so that the visibility of the time display, the function display, and the like can be further improved.

The windshield 4 has a main body portion 41 and an outer peripheral end portion 42. The main body 41 is formed in a circular diameter shape, and is formed in a flat shape in the vertical direction or a curved shape protruding upward. The outer peripheral end portion 42 is formed on the radial outer side of the main body portion 41. The outer peripheral end portion 42 is formed so as to project toward the back cover 5 side, that is, the downward side in the vertical direction. The outer peripheral end portion 42 is inserted from the upward side opening 21a side, and is held by interposing a waterproof member 6 with the outer peripheral wall 23 in the radial direction. The outer peripheral end portion 42 of the windshield 4 faces the outer wall portion 23 in the radial direction.
Here, the thickness of the outer peripheral end portion 42 is formed to be thinner than the thickness of the portion facing the upward side opening 21a in the vertical direction, that is, the main body portion 41. By reducing the thickness of the outer peripheral end portion 42, the space (accommodation space portion S2) up to the inclined portion 311 of the windshield 4 and the return ring 31 is widened as compared with the case where the thickness is the same when viewed from the vertical direction. This allows the hour character 32 to be increased. Therefore, it is possible to improve the visibility of the hour character 32 by the user.
In FIG. 3, the windshield 4 is fixed with the windshield 4 and the return ring 31 separated from each other by the interposition of the waterproof member 6, but the windshield 4 and the return ring 31 may be in contact with each other. Further, the windshield 4 is arranged on the flat end portion 311 of the dial ring 31, but is not limited to this, and may be arranged directly above the corresponding flat portion 24 of the body 2. Further, although it has been described that the outer peripheral end portion 42 of the windshield 4 has a shape that is inside the inner circumference of the outer wall portion 23 in the radial direction and is arranged in the accommodation space portion S2, the outer peripheral shape of the outer peripheral end portion 42 has been described. May be larger than the outer shape of the outer wall portion 23 on the outer peripheral side. Even in such a case, the windshield 4 can be fixed to the body 2 via the waterproof member 6.

As shown in FIGS. 1 to 4, the dial 34 is arranged between the pointer 33 and the movement 8 in the internal space S1 to protect the movement 8 and to give the user an aesthetic appearance of the watch 1. Has the function of giving. In the present embodiment, the dial 34 is composed of a transparent substrate 36, a decorative substrate 37 which is a decorative member, and decorative substrates 38A and 38B. The structure and arrangement of the dial 34 will be described in detail with reference to FIGS. 1 to 9. FIG. 5 is a front view of the dial 34 in the embodiment. FIG. 6 is a front view of the transparent substrate 36 in the embodiment. FIG. 7 is a front view of the decorative substrate 37 in the embodiment. FIG. 8 is a front view of the decorative substrate 38A in the embodiment. FIG. 9 is a front view of the decorative substrate 38B in the embodiment.

The dial 34 of the present embodiment has a multi-layer structure in which a decorative substrate 37, which is a decorative member, is laminated on a transparent substrate 36, and a decorative substrate 38A and a decorative substrate 38B are laminated on the decorative substrate 37. The dial 34 is inserted and fixed along the inner wall of the opening portion of the body 2. Therefore, on the inner wall of the opening portion of the body 2, a notch for the dial is provided so as to correspond to the thickness of each layer (transmissive substrate 36, decorative substrate 37, decorative substrate 38A, 38B) of the dial 34 having the multi-layer structure described above. 28 is formed.

The dial notch 28 is formed by being cut out radially outward from the inner peripheral surface 21c of the body 2 constituting the internal space S1. That is, the dial notch 28 is formed in an annular shape when viewed from the vertical direction, and is formed radially outside the opening 21a on the upward side. The notch 28 for the dial in the present embodiment is formed by a plurality of steps, and is composed of a first step 28a, a second step 28b, and a third step 28c, and is composed of a first step 28a. , The outer diameter becomes wider in the order of the second step portion 28b and the third step portion 28c. The first stepped portion 28a faces the decorative substrate 37 described later of the clock display unit 3 in the radial direction, and the outer peripheral end portion 37a of the decorative substrate 37 is inserted. The second step portion 28b faces the transmission substrate 36 in the radial direction, and the outer peripheral end portion 36a of the transmission substrate 36 is inserted. The third step portion 28c faces the holding plate 84 of the movement 8 described above in the radial direction.

As shown in FIGS. 1 to 6, the transmission substrate 36 is housed in the internal space portion S1. The transparent substrate 36 faces the windshield 4 in the vertical direction and has transparency. The transparent substrate 36 in the present embodiment is formed in a circular shape and is made of a transparent resin material. That is, since the transparent substrate 36 is transparent, the user can visually recognize at least a part of the internal space portion S1 through the windshield 4 and the transparent substrate 36. The outer diameter of the transparent substrate 36 is formed to be larger than the opening diameter of the upward side opening 21a when viewed from the vertical direction, and the outer peripheral end portion 36a is inserted into the second step portion 28b of the notch portion 28 for the substrate.
