Abstract

<P>PROBLEM TO BE SOLVED: To provide a timepiece capable of improving the winding-up efficiency by an automatic wind-up mechanism while using both of a manual wind-up mechanism and the automatic wind-up mechanism. <P>SOLUTION: An engaging and disengaging means 70 of a computerized mechanical timepiece 1 is composed of an intermediate transmission shaft 72 on a convex lens, and a circular hole 71 of a transmission intermediate wheel 45 fitted to the intermediate transmission shaft 72, and the transmission intermediate wheel 45 is disengaged from a transmission wheel 60 in automatic winding-up by a rotary weight. Accordingly, the intermediate wheel 45, a circular hole wheel 44, and a winding pinion 43 are not rotated in automatic winding-up, as a result, much rotational energy of the rotating weight can be used for winding-up a spring 10, which improves the winding-up efficiency. When the spring 10 is winded up by operating the winding stem 41, the transmission intermediate wheel 45 is engaged with the transmission wheel 60, thereby, the rotation of the winding stem 41 is transmitted to manually wind-up the spring 10. <P>COPYRIGHT: (C)2004,JPO

らきち車に伝達され、伝え車を一方向に回転させる。[0003] In general, a manual winding mechanism manually rotates a crown integrated with a winding stem to transmit its rotation from a clutch wheel to a transmission wheel through a pinion wheel, a round hole wheel, and a transmission intermediate wheel. It is configured to rotate the square wheel that meshes with the transmission wheel and wind up the mainspring. At this time, a ratchet mechanism is formed between the clutch wheel and the ratchet wheel, and by rotating the winding stem in only one direction, this rotation is transmitted from the clutch wheel to the ratchet wheel and the transmission wheel is transmitted. Rotate in one direction.

低下させていた。However, in the automatic hoisting mechanism, the transmission member rotates the transmission wheel in one direction. However, since the transmission intermediate wheel of the manual winding mechanism meshes with this transmission wheel, this transmission intermediate wheel is engaged. The car also rotates at the same time. In addition, since the round wheel meshes with the transmission intermediate wheel and the gear wheel meshes with the round hole wheel, they also rotate at the same time. That is, the rotational energy of the rotary weight in the automatic hoisting mechanism is not only consumed for hoisting the mainspring, but is also consumed for rotating the transmission intermediate wheel, round hole wheel and pinion wheel of the manual hoisting mechanism. This causes a large load (energy loss) and reduces the winding efficiency.

構による巻上げ効率を低下させていた。Further, a ratchet mechanism is formed between the clutch wheel and the ratchet wheel, and when the ratchet wheel rotates from the automatic winding mechanism side, the ratchet wheel overcomes the biasing force (spring force) of the bolt. It moves in the axial direction of the winding stem, disengages from the ratchet wheel, and the rotation of the ratchet wheel is not transmitted to the winding stem.The load when disengaging the clutch wheel and the ratchet wheel It was also large, which also reduced the winding efficiency of the automatic winding mechanism.

Most of the car does not rotate, the rotational energy of the rotary weight is more consumed for winding the mainspring, and the winding efficiency of the mainspring is improved. Further, since the wheel on the manual winding mechanism side does not rotate, it is not necessary to disengage the clutch wheel and the ratchet wheel provided on the side close to the winding stem against the urging force of the bolt. However, energy loss is suppressed and the winding efficiency of the automatic winding mechanism is improved. When the mainspring is manually wound by operating the winding stem, the wheel of the manual winding mechanism is engaged with the vehicle side, so the rotation of the winding stem is transmitted to wind the mainspring, and the manual winding mechanism and automatic winding mechanism The mechanism can be used together without any problems.

上げ機構によるぜんまいの巻上げ効率が最良となる。In the timepiece of the present invention, it is preferable that the wheel that is disengaged is an intermediate transmission wheel that is disengageable from the transmission wheel. According to the timepiece having such a configuration, in particular, even in the vehicle of the manual winding mechanism, the transmission intermediate wheel that directly meshes with the transmission wheel is disengaged, so that all the vehicles on the manual winding mechanism side do not rotate during the automatic winding. Therefore, the winding efficiency of the mainspring by the automatic winding mechanism becomes the best.

It may have been done. According to the timepiece having such a structure, the wheel provided in the manual hoisting mechanism so that the wheel can be disengaged is pivotally supported by the fixed shaft that is inserted into the shaft insertion hole of the vehicle. Since it is inserted in the insertion hole in a loosely fitted state, a gap is formed between the fixed shaft and the shaft insertion hole, and the vehicle swings by this gap to ensure that the transmission wheel side is not disengaged. Will be done.

るようになる。In the timepiece of the present invention, it is preferable that the shaft insertion hole is a round hole, and the fixed shaft is formed in a convex lens shape in cross section having a thick central portion and a thinner peripheral portion. According to the timepiece having such a structure, since the shaft insertion hole is a round hole and the fixed shaft has a convex lens shape in section, the car that can be disengaged meshes with the transmission wheel side at the time of winding by the manual winding mechanism. If so, the car rotates smoothly while contacting the arc surface of the fixed shaft. In addition, since the shaft insertion hole is a round hole, the fixed shaft having a convex lens-shaped cross section satisfactorily contacts any portion of the inner circumference of the shaft insertion hole regardless of the rotation (rotation) position of the vehicle. . Then, in the shaft insertion hole, a crescent-shaped gap is formed in a portion other than the fixed shaft having a convex lens-like cross section, and the car is disengaged by utilizing this gap.

するだけでよく、構造が簡単である。In the timepiece of the present invention, the biting-out means may be configured to be able to bite out the wheel by a ratchet mechanism. In a timepiece having such a configuration, the rotation of the transmission wheel is not transmitted to the vehicle on the manual winding mechanism side by the ratchet mechanism during the winding by the automatic winding mechanism, and the rotation of the winding stem is transmitted through the vehicle only during the manual winding. As a result, it is transmitted to the vehicle, and the gear on the side of the manual hoisting mechanism is surely engaged with and disengaged from the transmission wheel. Further, in this configuration, it is only necessary to devise the tooth profile of the vehicle or the tooth profile of the transmission wheel, and the structure is simple.

伝え車側から確実に外れるようになる。In the timepiece of the present invention, the car can be held against the self-weight of the car to be bitten out and has a holding force smaller than the force for disengaging the car on the winding stem side of the car. It is desirable to have a holding member. In the timepiece having such a structure, since the holding member has a holding force against the own weight of the car that can be bitten off, even if the direction in which the own weight of the vehicle acts changes due to the change in the attitude of the watch, the holding member The car is held securely by the car and there is no need to worry about the car moving carelessly. Therefore, when meshing with the transmission wheel side, the meshed state is reliably maintained with respect to the change in the attitude of the timepiece, and when disengaged, the disengaged state is reliably maintained. Since the vehicle is held with a predetermined holding force of the holding member, when operating the winding stem from the disengaged state to engage the winding stem, the rotating force from the winding stem side causes the vehicle to spin on the spot. Without rotating, it will surely move to the transmission side and mesh with it while rotating. Further, when the vehicle is being held by the holding member and is about to be disengaged from the transmission wheel side, on the winding stem side of this vehicle, the meshing force between the other vehicles exceeds the holding force of the vehicle by the holding member. Since these other vehicles do not rotate at all, the vehicle revolves around another vehicle (for example, a round hole wheel in the embodiment described later) that meshes with this on the winding true side. To move,
It will surely come off from the car side.

る。In the timepiece of the present invention, the holding member may be provided so as to push the wheel that bites out in the axial direction, or may be provided so as to push in the radial direction. The holding member that pushes the biteable wheel in the axial direction is used well when the vehicle is disengaged from the transmission wheel in the radial direction or in the axial direction and is pressed in the radial direction. The holding member is particularly effective when the vehicle is dislocated in the radial direction.

This round hole car, said intermediate car,
It is desirable that the transmission pinion of the transmission wheel that meshes with the transmission intermediate wheel and the square hole wheel that meshes with the transmission pinion be arranged at substantially the same height position in a sectional view. Vehicles with manual hoisting mechanism such as round hole wheel, transmission intermediate wheel, transmission wheel and square hole wheel have very large reaction force (radial reaction force) generated when winding the mainspring. And load countermeasures become important. In particular, if the meshes of the vehicles are largely displaced in the axial direction, the reaction force applied to the shaft is also displaced in the axial direction, and a large moment is generated on the contact surface such as the outer diameter of the vehicle, resulting in a large load. On the other hand, in the timepiece of the present invention, since each car is arranged at substantially the same position in the axial direction, the position of the load applied to each car becomes substantially the same in the axial direction,
When the mainspring is wound up, the moment generated on the contact surface of each car is reduced, and the generation of load is suppressed.

い。In the timepiece of the present invention, the automatic winding mechanism includes a pawl lever that operates in conjunction with the rotation of the rotary weight and that engages with the transmission wheel to rotate the transmission wheel in one direction. It is desirable that the pawl lever be disengaged from the transmission wheel when the transmission wheel is driven by the manual hoisting mechanism. According to the timepiece having such a configuration, the claw lever is disengaged from the transmission wheel when the manual winding mechanism winds the winding wheel. Therefore, even if the manual winding mechanism rotates the transmission wheel, this rotation is transmitted to the rotary weight side. No need to worry about rotating the weight when rotating the winding stem.

なる。In the timepiece of the present invention, it is desirable that, in a plan view from the rotary weight side, the wheel that disengages, the transmission wheel, and the mainspring are arranged on the left side of the winding stem. In a timepiece having such a structure, the mainspring is wound up by rotating the winding stem clockwise like a normal timepiece (a timepiece having a mainspring) while reducing the number of cars constituting the manual winding mechanism. As a result, the usability is improved.

械時計に本発明を適用するメリットは大きい。In the timepiece of the present invention, the mainspring is used as an energy source to drive the train wheel, and electric power is generated in the rotating generator by receiving rotation from the train wheel. It is preferable that the electronic timepiece is a mechanical timepiece in which the train wheel is braked to control the speed by controlling the rotation cycle of the machine. In electronically controlled mechanical watches, the mainspring torque is generally the system torque (the torque required for control to move the pointer accurately).
Since it is set to a higher value in consideration of the above, the reaction force during winding, for example, with the clutch wheel and ratchet wheel becomes larger, and the meshing with the clutch wheel and ratchet wheel during automatic winding becomes larger. The removal force for removing On the other hand, in the timepiece of the present invention, by disengaging the vehicle that constitutes the manual winding mechanism from the transmission side, it is not necessary to disengage the clutch wheel and the ratchet wheel in the first place. Therefore, it is not necessary to provide a large removing force for the rotation energy of the rotary weight. Therefore, it is sufficient to set the rotating weight to a size corresponding to the mainspring torque, and it is not necessary to consider such disengaging force, so that the increase in size is suppressed and the overall size of the electronically controlled mechanical timepiece is increased. Suppressed. Therefore, the merit of applying the present invention to an electronically controlled mechanical timepiece which is difficult to escape from a large size is great.

ときには、外れた状態を確実に維持できる。(8) Holding member 7 which constitutes biting means 70
Since 3 has a holding force against the own weight of the transmission intermediate wheel 45, even if the direction in which the own weight of the transmission intermediate wheel 45 acts changes due to a change in the attitude of the electronically controlled mechanical timepiece 1, the holding member 73 The transmission intermediate wheel 45 can be reliably held, and the transmission intermediate wheel 45 can be prevented from moving carelessly. Therefore, when the transmission intermediate wheel 45 meshes with the transmission wheel 60, the meshed state can be reliably maintained against the change in the attitude of the electronically controlled mechanical timepiece 1, and when the meshing is disengaged, the disengaged state is maintained. Can be reliably maintained.

ができる。(9) Since the intermediate wheel 45 is held by the holding force of the holding member 73, when operating the winding stem 41 from the disengaged state and engaging the winding stem 41 from the winding stem 41 side. It is possible to prevent the transmission intermediate wheel 45 from idling on the spot by the rotational force of the transmission intermediate wheel 45, and to move the transmission intermediate wheel 45 while rotating it so that the transmission intermediate wheel 45 can surely mesh with the transmission wheel 60.

Since the meshing force with the ratchet wheel 43 is superior, the rotation of the clutch wheel 42, the ratchet wheel 43, and the round hole wheel 44 can be suppressed, and the transmission intermediate wheel 45 can be moved around the round hole wheel 44. It can be moved so that it revolves around the sun, and can be reliably removed from the transmission wheel 60.

る。(12) Conventionally, in the case of reducing the energy loss by reducing the disengagement force for disengaging the ratchet mechanism portion of the ratchet wheel 42 and the pinion wheel 43 so as to easily disengage during rotation of the rotary weight 51. However, in this case, even when the winding stem 41 is rotated, the clutch wheel 42 may be disengaged from the tight wheel 43. Therefore, it is necessary to set the release force that satisfies both the energy loss suppression and the reliable transmission of the rotation of the winding stem 41, but this setting is very delicate and unstable, and the winding stem 41 is rotated. However, there was a problem in reliability such as the mainspring 10 not winding up. On the other hand, in the present embodiment, the rotary weight 51
Since the rotation of the ratchet mechanism 42 is not transmitted to the clutch wheel 42 and the pinion wheel 43, the releasing force of the ratchet mechanism portion is set so as to be surely released when the winding stem 41 is rotated in the direction opposite to the winding direction, and is held. It may be set to be larger than the holding force of the member 73, and since it is not necessary to consider the energy loss of the rotary weight 51 at all, the setting can be performed easily and reliably.
The reliability of the manual hoisting mechanism 40 can be improved.

At the time of winding by the automatic winding mechanism 50, it is unnecessary to disengage the clutch wheel 42 and the ratchet wheel 43 in the first place. There is no need to cover the rotational energy of 51. For this reason, the rotary weight 51 may be set to a size corresponding to the mainspring torque, and it is possible to suppress the increase in size as much as there is no need to consider such a removing force, and the overall size of the electronically controlled mechanical timepiece 1 is increased. Can also be suppressed.

When the inclined surface 60B is provided at a portion that contacts the teeth of the transmission intermediate wheel 45, and the transmission pinion 60A (transmission wheel 60) is rotated by the automatic winding mechanism 50 and is on the drive side with respect to the transmission intermediate wheel 45. (The transmission intermediate wheel 45 is on the driven side), its inclined surface 60B contacts the teeth of the transmission intermediate wheel 45,
5 is removed downward against the holding force of the holding member 93 (see the arrow in the figure). On the other hand, when the transmission of the intermediate wheel 45 by the manual hoisting mechanism 40 is on the drive side,
(0A is the driven side), the teeth of the transmission intermediate wheel 45 are 60A.
The tooth surface 60C (the surface on the side opposite to the inclined surface 60B) of the tooth of the tooth is engaged and meshed, and the rotation of the winding stem 41 is transmitted to the transmission wheel 60 to wind up the mainspring 10. Therefore, this ratchet mechanism constitutes the biting-out means according to the present invention.

During automatic winding by the rotary weight 51, the transmission intermediate wheel 45 of the manual winding mechanism 40 moves the transmission wheel 60 and the round hole wheel 44.
Since the transmission intermediate wheel 45, the round hole wheel 44, and the pinion wheel 43 of the manual hoisting mechanism 40 do not rotate during the rotation of the rotary weight 51, the rotational energy of the rotary weight 51 is increased more by the winding of the mainspring 10. Therefore, the winding efficiency of the mainspring 10 can be improved.

より顕著にできる。Further, the holding member 93 presses the transmission intermediate wheel 45 axially with respect to the fixed shaft 62, but since the transmission intermediate wheel 45 has a structure which moves along the axial direction and comes off, The energy consumed to disengage the intermediate wheel 45 from the transmission wheel 60 is sufficient to overcome the retaining force of the retaining member 93, and the disengaging force for disengaging the clutch wheel 42 and the ratchet wheel 43 has no effect. Therefore, the holding member 93 is used to set the removal force of the clutch wheel 42 and the pinion wheel 43.
It is possible to set even the holding power of, regardless of, and the effect of (12) described above can be made more prominent.
