Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic timepiece for diving, and more particularly to an auxiliary power generation technique for the electronic timepiece.

[0002]

2. Description of the Related Art A so-called diving computer dedicated to diving has already been devised as a device for measuring the depth of a dive and other values and displaying them. According to this dive computer, in addition to the depth of the dive and the like, it also displays how much water on the surface should be reserved for the next dive.

[0003]

However, the conventional diving computer has a problem that it is inconvenient because it does not have a built-in clock function for the purpose of reducing the power consumption. That is, the diving computer
Since it is used while being carried, there is a lot of information to be displayed even though the size of the battery is limited. Therefore, if a function such as a clock function that needs to continue displaying information is installed, the battery is likely to run out during diving, which is not only inconvenient, but also the safety of the diver cannot be ensured.

In view of the above problems, the object of the present invention is to
It is to realize an electronic timepiece for diving in which the battery does not run out during diving even if a display function for time and dive recording data is added.

[0005]

In order to solve the above-mentioned problems, the present invention has a display device for displaying at least time information and diving record data, and a display control means for controlling the display operation of this display device. The watch body is connected to the diving breathing apparatus via a ventilation pipe, and is connected to the turbine chamber to which the air flow is supplied from the diving breathing apparatus side, and is arranged in this turbine chamber and is rotated by the air flow passing therethrough. And a power storage element that stores electric energy generated by the auxiliary power generation means and supplies electric power to the display device and the display control means. Have. That is, the turbine is rotated by compressed air supplied directly from the diving breathing apparatus, inhalation supplied from the diving breathing apparatus to the mouthpiece, or compressed air supplied from the diving breathing apparatus is exhaled from the mouthpiece. It is characterized by the provision of auxiliary power generation means.

According to such a configuration, even if the power consumption is increased due to the provision of the function for displaying the time and diving record data, since the power can be generated during the diving, the battery does not run out. Moreover, since there is no problem of running out of battery, it is possible to improve display quality or enrich display information.

In the present invention, it is preferable that a rotary weight that is rotated by an external force applied to the timepiece body and a main power generation means that is driven by the rotary weight to generate power and store electrical energy in a storage element are provided. . That is, the auxiliary power generation means driven by the turbine and the normal AGS (main power generation means) driven by the rotary weight, that is, JP-A-52
It is preferable to provide both a power generation device utilizing the movement of the arm and gravity as disclosed in Japanese Patent Publication No. 82478. In this case, it is preferable that the main power generation means and the auxiliary power generation means share the power generation rotor or the power generation coil. With such a configuration, even if the battery runs out in a region where the battery cannot be obtained or replaced, it is convenient because the main power generation means generates power while carrying the electronic timepiece for diving. Also, even if the battery runs out during long-term storage, it can be used without purchasing the battery.

In the present invention, it is preferable that the wristwatch is connected to the wristband.

According to the present invention, the pipe attaching / detaching portion for connecting the ventilation pipe to the turbine chamber is formed on the case body of the timepiece body, and the pipe attaching / detaching portion for connecting the ventilation pipe to the turbine chamber is a wrist band. In the latter case, the air passage extending from the pipe attachment / detachment section to the turbine chamber is formed on the side of the arm mounting band. Here, the pipe detaching portion is in a state of covering the pipe detaching portion when the ventilation pipe is not connected to the turbine chamber, and in this state, the pipe detaching portion is opened when connecting the ventilation pipe to the turbine chamber. It is preferable to provide a shutter mechanism that switches to the state.

In the present invention, the watch body is divided into a first case body in which the display device is arranged and a second case body in which the turbine chamber is formed. It is preferable to provide a back cover that can open the turbine chamber. Since dust etc. is likely to accumulate inside the turbine chamber,
This is so that maintenance can be performed easily.
Further, it is preferable to cover the turbine chamber with a transparent cover so that it is possible to easily confirm whether or not dust is accumulated inside the turbine chamber and whether or not the turbine moves.

Further, it is preferable that a satellite positioning system is provided on the timepiece main body, and the positioning result of this satellite positioning system is also displayed on the display device by the display control means. This is because, in the sea, the visibility may deteriorate suddenly as the direction interval becomes weaker.

In the present invention, it is preferable to use a microdot type liquid crystal display panel having a backlight as a display device.

Further, a power generation section monitoring means for monitoring whether or not the turbine room is connected to the ventilation pipe is provided, and the display control means determines that the ventilation tube is installed in the turbine room based on the monitoring result of the power generation section monitoring means. When it is determined that they are connected, the display means performs a display operation with a large load, and when it is determined that the ventilation pipe is not connected to the turbine chamber, only a display operation with a small load is performed on the display means. It is preferable to perform it. Further, when a liquid crystal display panel equipped with a backlight is used, the display control means displays the liquid crystal display when it determines that the ventilation pipe is connected to the turbine chamber based on the monitoring result of the power generation section monitoring means. Display operation is performed with the backlight on the panel, and when it is determined that the ventilation pipe is not connected to the turbine chamber, the display operation is performed with the backlight off for the liquid crystal display panel. It is preferable that it can be performed. Here, when the power generation unit monitoring means monitors whether the ventilation pipe is connected to the turbine chamber or not inside the pipe detaching unit,
Any configuration may be used for monitoring whether or not the turbine is rotating.

[0014]

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing the appearance of the electronic timepiece for diving of this example, and FIG. 2 is a side view of the timepiece body.

(Overall Structure) In FIG. 1, an electronic timepiece 1 for diving of this example has a timepiece body 1 similar to an ordinary electronic timepiece.
A display surface 31 of the liquid crystal display device 3 is provided on the upper surface of the case 0 of 0, and normal time is digitally displayed on the display surface 31. Further, the display surface 31 of the liquid crystal display device 3
It also displays the diving record data such as the water temperature during diving, the passage of diving time, the internal pressure value of the atmospheric cylinder, and the depth. Since the liquid crystal display device 3 is a microdot type liquid crystal display panel provided with a backlight, bright and clear display is possible. Moreover, various information can be displayed while the display surface 31 is divided into arbitrary areas.

In the electronic timepiece 1 for diving of this example, a slide switch 4 of a three-position type is constructed so as to project from the case 2, and as will be described later, the display surface 3
The contents displayed in 1 can be switched.

As shown in FIG. 2, the electronic timepiece 1 for diving includes:
Upper half 11 (first case body) with built-in clock function etc.
And the lower half 12 (second case body) are joined to each other by screws at four places to form a two-piece structure, which is partitioned from each other by a partition wall. Therefore, the user can easily exchange the color plate sandwiched between the upper half 11 and the lower half 12 and enjoy the color design according to his / her preference. Further, the lower half portion 12 is formed with a back cover 13 that opens the inside thereof, and a band mounting groove 15 for connecting the wrist mounting band 14 to the watch body 10. Therefore, since the watch body 10 can be dived with the wrist band 14 attached to the wrist, the display surface 3
The display of No. 1 can be seen immediately, and the timepiece body 10 does not hit marine organisms and cause damage.

The watch body 10 is provided with a detector group 90 such as a cylinder pressure measuring sensor 91, a water depth measuring sensor 92, a satellite positioning system 93 (GPS), and a temperature sensor 94.

(Power Generation System) FIG. 3 is a configuration diagram showing a usage state of the electronic timepiece for diving of this example.

FIG. 3 shows the inside of the electronic timepiece 1 for diving of this example.
As schematically shown in FIG. 1, a rotary weight 51 that is rotated by an external force applied when the user moves while wearing it on his arm.
A power generation rotor 52 to which the rotational driving force of the rotary weight 51 is transmitted via the train wheel, and a power generation coil 53 that generates an electromotive force by the rotation of the power generation rotor 52 are arranged. . Thus, in this example, the main power generation system 5 including the power generation rotor 52 and the power generation coil 53 is configured. Electric power generated by the main power generation system 5 is stored in a capacitor 55 (electric storage element) via a rectifying circuit or the like, and the capacitor 55 serves as a power source for the electronic timepiece 1 for diving. The configuration of this power generation system is disclosed in Japanese Patent Application Laid-Open No. 52-82478, and the detailed description thereof will be omitted.

Further, in this example, the case 2 also projects to the side opposite to the slide switch 4, and inside the projecting portion 21, there is a turbine chamber 61 whose side end face is open to the inlet and the outlet. Has been formed. The upper surface of the turbine chamber 61 is covered with a transparent glass cover 22 (transparent cover), and what can be seen through from the glass cover 22 is a turbine 62 arranged inside the turbine chamber 61. The turbine 62 includes an auxiliary power generation rotor 63.
Are integrally formed, and an auxiliary power generation coil 64 is arranged around the auxiliary power generation rotor 63. That is, the auxiliary power generation rotor 63 and the auxiliary power generation coil 64 configure the auxiliary power generation system 6. The power generated by the auxiliary power generation system 6 is also stored in the capacitor 55 (storage element) via a terminal, a rectifying circuit, and the like.

In the present example, the auxiliary power generation system 6 (the turbine chamber 61 and the turbine 62) is all in the timepiece body 1.
It is configured in the lower half 12 of 0. In the lower half portion 12, when the back cover 13 is removed, the turbine chamber 61 and the turbine 6 are removed.
Since 2 is exposed, dust and the like accumulated there can be easily removed. However, even when the back cover 13 is removed, the upper half 11 having the built-in clock function and display function remains completely sealed, so that the user does not touch them.

In this example, the main power generation system 5 and the auxiliary power generation system 6 each have a power generation rotor or a power generation coil.
For the train wheel from the rotary weight 51 to the power generation rotor 52,
The turbine 62 of the auxiliary power generation system 6 may be configured to transmit the rotational force to any of the gears that configure it. In this case, the power generation rotor or the power generation coil can be shared between the main power generation system 5 and the auxiliary power generation system 6. However, for the purpose of reducing the load on the train wheel, for example, when an air flow is supplied to the turbine 62 of the timepiece body 10 by providing a train wheel switching mechanism, the train wheel and the rotary weight 51 of the main power generation system 5 are supplied.
A switching mechanism is provided to release the connection with.

(Induction Structure for Auxiliary Power Generation System) As shown schematically in FIG. 3, the auxiliary power generation system 6 includes a compressed air cylinder 7 of a diving breathing apparatus which becomes a breathing air source of a diver during diving. The turbine 62 is rotated by the intake air supplied to the mouthpiece 71. For this reason, in this example, in the intake path 72 from the compressed air cylinder 7 to the mouthpiece 71, a cylinder side ventilation pipe 721 having a double pipe structure is provided between the first stage 79 of the compression cylinder 72 and the pressure regulating valve 74. The watch side ventilation pipe 75 having a double pipe structure is connected to the ventilation pipe.
Therefore, the airflow can be supplied from the compressed air cylinder 7 to the turbine chamber 61. A rectifying valve 77 shown in FIG. 4 is used to connect the cylinder side ventilation pipe 721 and the timepiece side ventilation pipe 75. This rectifying valve 77 has a marker 771
Is described, and the air flow is supplied from the cylinder side ventilation pipe 721 in the direction indicated by the marker 771.

For example, as shown in FIG.
When 71 is directed toward the watch side ventilation pipe 75, the arrow Ai
As indicated by r1, compressed air from the compressed air cylinder 7 side (first stage 79 side) is supplied to the cylinder side ventilation pipe 7
The gas is supplied to the turbine chamber 61 through the inner passage of 21 and the inner passage (air supply pipe 73) of the clock side ventilation pipe 75. Further, compressed air is returned from the turbine chamber 61 to the pressure regulating valve 74 via the outer passage (exhaust pipe 74) of the timepiece-side ventilation pipe 75 and the outer passage of the cylinder-side ventilation pipe 721, as indicated by arrow Air2. It is like this.

On the other hand, when the marker 771 is directed toward the cylinder side ventilation pipe 721, the inside passage and the outside passage of the cylinder side ventilation pipe 721 are connected. That is, the compressed air from the first stage 79 side of the compressed air cylinder 7 is directly supplied to the valve 74 side without passing through the timepiece side ventilation pipe 75 and the turbine chamber 61 as shown by an arrow Air3.

Further, in this embodiment, the hose joint 76 shown in FIG. 5 is used to connect the timepiece ventilation pipe 75 and the timepiece body 2.
To use. FIG. 5 is an explanatory view of a connection portion of the electronic timepiece for diving, the timepiece-side ventilation pipe, and the timepiece body.

In FIG. 5, a pipe attaching / detaching portion 60 is formed on the side of the timepiece body 2 which is recessed at the side end surface of the projecting portion 21 of the case 2, and a hose joint 76 is attached thereto. In the pipe detaching unit 60, the turbine chamber 61
Two vent passages 611, 612 open from to respectively as an inlet 613 and an outlet 614. On the other hand, on the side of the hose joint 76, the air supply pipe 7 of the watch side ventilation pipe 75 is provided.
3 and the exhaust pipe 74 are branched, and the hose joint 7
6 is attached to the pipe attaching / detaching portion 60, the air supply pipe 73 is connected to the inlet 61.
The exhaust pipe 74 is connected to the outlet 614. Between the hose joint 76 and the pipe attaching / detaching portion 60, a known lock mechanism (not shown) that automatically becomes a locked state when the hose joint 76 is inserted into the pipe attaching / detaching portion 60 is configured. On the other hand, on the side surface of the hose joint 76, a lock release button 761 for releasing the lock mechanism between the hose joint 76 and the pipe attaching / detaching portion 60 is formed.

In the turbine chamber 61, the compressed air from the compressed air cylinder 7 is supplied with the cylinder pressure as it is. Therefore, by arranging the cylinder pressure measuring sensor 91 in the pipe attaching / detaching portion 60, the internal pressure of the compressed air cylinder 7 is increased. Can be measured. The signal from the cylinder pressure measuring sensor 91 is input to the data signal input unit 103 of the control IC 100a (display control means) inside the timepiece body 2.

A sensor 66 for monitoring whether or not the hose joint 60 is mounted is arranged in the pipe attaching / detaching portion 60, and the detection result is a monitoring signal of the control IC 100a inside the timepiece body 2. It is input to the input unit 105. The purpose is to make the electronic timepiece 1 for diving exhibit a relatively large power consumption function only when the hose joint 60 is attached, that is, when the auxiliary power generation system 6 is ready for power generation. is there. For example, the liquid crystal display device 3 can perform display while the backlight is on. On the other hand, when the hose joint 60 is not attached, only the function of relatively low power consumption is exerted. For example, the liquid crystal display device 3 is caused to perform display with the backlight turned off.
This is because the backlight consumes the largest power among the components of the electronic timepiece 1 for diving in this example. Here, a sensor 67 that monitors whether or not the turbine 62 is rotating may be arranged in the turbine chamber 61, and the backlight may be turned on only while the turbine 62 is rotating, that is, during actual charging.

Further, when the hose joint 76 is removed from the pipe attaching / detaching portion 60, the shutter 69 automatically covers the pipe attaching / detaching portion 60, and when the hose joint 76 is inserted from this state. , Shutter 69
The shutter mechanism 68 is configured so that the hose joint 76 can be attached to the pipe attaching / detaching portion 60 by being automatically pushed away. Therefore, when the electronic timepiece for diving 1 is used in daily life, even if it is carried without connecting the hose joint 76, dust or the like does not enter the turbine chamber 61, and the fashionability is high. Further, even if the electronic timepiece for diving 1 is used for diving without being connected to the hose joint 76, dust in the sea does not enter the turbine chamber 61. In addition, when the shutter mechanism 68 is waterproof, seawater does not enter the turbine chamber 61 even if the user dives as it is.

The hose attaching / detaching portion 60 may be formed on the arm mounting band 14 instead of being provided on the case 2. In this case, the two ventilation passages 61 connecting the hose attachment / detachment portion 60 formed on the arm mounting band 14 and the turbine chamber 61.
1, 612 are formed on the side of the wrist mounting band 14.

As described above, in the present example, the timepiece main body 10 has
Since the auxiliary power generation system 6 that generates power by the airflow of the diving breathing apparatus is configured, power can be generated even during diving. Therefore, even if a lot of information such as the time display and the dive record data is displayed, the battery will not run out during the dive. Further, since the normal AGS driven by the rotary weight 51 is also provided, even if the battery runs out in a region where the battery cannot be obtained or replaced, the electronic timepiece 1 for diving can be charged while being carried.

(Switch operation) Referring again to FIG. 3,
The switch operation for switching the operation of the electronic timepiece 1 for diving of this example will be described.

In this example, a single electronic timepiece 1 for diving is equipped with a plurality of functions. However, for the purpose of improving operability, most of the functions can be switched by operating the slide switch 4. There is. Further, in each mode, only the slide switch 4 needs to be operated when changing the condition.

First, when the slide switch 4 is slid from the normal position P0 shown by the solid line in FIG. 3 to the first switching position P1 shown by the one-dot chain line or the second switching position P2 shown by the two-dot chain line, a locking sound is produced. As a result, the slide switch 4 is locked. This operation is a hard touch operation, and this operation switches the mode. Also, a soft touch operation is to lightly move the slide switch in the upward direction (direction of arrow A) or in the downward direction (direction of arrow B). By this operation, the set value and data in each mode can be switched. It is possible.
Furthermore, pushing the slide switch 4 from the lateral direction (direction of arrow C) is a push operation, and by this operation, the locked state can be released and reset. In addition, a plurality of buttons (not shown) are formed on the side surface of the case 2, and when this button is pressed, the corresponding display (time, alarm set time, etc.) blinks, and in this state, By performing a soft touch operation, it is possible to change the time, the alarm set time, and the like.

(Structure of Control Unit) Next, the structure of the control unit incorporated in the electronic submersible timepiece of this embodiment will be described with reference to FIG. FIG. 6 is a block diagram showing the configuration of the control unit of this example.

00a is mounted and operates based on the program stored in the program memory 104.

In the control IC 100a, the operation signal input section 101 uses the content of the hard touch operation performed on the slide switch 4 as a signal SA to output the core CPU 1
Enter 00. Further, the operation signal input unit 101 outputs the content of the soft touch operation performed on the slide switch 4 as a signal SB, and outputs the presence or absence of the push operation as a signal SC.

The data signal input section 103 is used for the watch body 10
The core CPU 100 uses the detection results of the detector group 90 such as the cylinder pressure measuring sensor 91, the water depth measuring sensor 92, the satellite positioning system 93, and the temperature sensor 94 provided in the core CPU 100 as a signal SD.
To enter. The monitoring signal input unit 105 uses the result of the sensor 66 monitoring whether or not the hose joint 76 is connected to the timepiece body 10 as a signal SE to the core CPU 100.
To enter.

In the data memory 102, in addition to a counter for storing time data 102a such as current time and calendar, logbook data 102b such as surface rest time rank and no-decompression limit time, diving profile and maximum depth, etc. A counter for storing diving record data such as the profile data 102c of FIG. Further, in the present example, the data memory 102 is also configured with a counter for recording the positioning data 102d such as the direction and distance data of the GPS entry point.
The control IC 100a thus configured constitutes a display control unit that controls the display operation performed by the liquid crystal display device 3.

Further, the core CPU 110 issues a command to sound an alarm to the alarm device 110 when the residual pressure of the compressed air cylinder 7 falls below a predetermined condition. .

In this mode, when a soft touch operation is performed on the slide switch 4 and the slide switch 4 is slid upward (in the direction of arrow A), the depth rank is increased and the slide switch 4 is slid in the downward direction (direction of arrow B). And, the depth rank is designed to descend. This mode can be used when planning a dive, because a predetermined dive condition is set in accordance with such a condition change.

[Profile Mode on Land] In the state where the slide switch 4 is slid to the second switching position P2 until it is locked and the hose joint 76 is not connected, the dip recording performed so far is as follows. The date, dive time, exit time, dive profile, water temperature at MAX depth, maximum depth, average depth, and tank level are displayed. In this mode, when a soft touch operation is performed on the slide switch 4 and the slide switch 4 is slid upward (in the direction of arrow A), the oldest dive record is displayed starting from the latest dive record. On the other hand, when the slide switch 4 is slid downward (in the direction of arrow B), the new dive record is displayed in order from the oldest dive record. This mode is used to record diving records in the logbook and to plan diving.

[Dive table mode during dive] When the slide switch 4 is slid to the first switching position P1 until the lock state is established and the hose joint 76 is connected, as shown in FIG. 7 (d). The dive table during diving is displayed on. That is, the dive profile such as the limit time at the set water depth, the maximum depth and the current depth, the remaining time, the dive point, and among the display contents in the main mode, the dive time, the depth rank, the tank remaining amount, the tank remaining amount graph, etc. are displayed. It In this mode, when a soft touch operation is performed on the slide switch 4 and the slide switch 4 is slid upward (in the direction of arrow A), the depth rank is increased and the calculation result of the remaining time is displayed accordingly. On the other hand, when the slide switch 4 is slid downward (in the direction of arrow B), the depth rank is lowered and the calculation result of the remaining time is displayed accordingly.

Further, when the turbine chamber is covered with the transparent cover, it is possible to easily check whether or not dust is accumulated inside, and also it is possible to easily check whether or not the turbine moves.

When the positioning result of the satellite positioning system is also displayed on the display device, the diver's safety can be ensured even if the direction interval in the sea becomes weak and the field of view suddenly deteriorates.

When a microdot type liquid crystal display panel having a backlight is used as the display device, information can be confirmed under the sea without illuminating the display surface of the display device with a light. In addition, the microdot method can clearly display a large amount of information in an arbitrary pattern.

When the turbine room is not connected to the passage of the diving breathing apparatus based on the monitoring result by the power generation unit monitoring means, when only the display operation with a small load is performed, there is no electric power margin. It is possible to save power.
