Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mainspring mechanism module for operating a drive mechanism by the power of a mainspring and a device using the same.

[0002]

2. Description of the Related Art Conventionally, in order to assemble a mainspring mechanism module into a drive mechanism such as a lid or a door of equipment, it is necessary to assemble it with an initial number of windings so that a torque required to drive the drive mechanism is generated. was there.

Further, as disclosed in Japanese Patent Laid-Open No. 59-222631, after assembling, a thin pin or the like is inserted from the outside of the mainspring accommodating portion into a cylindrical hole rounded into a cylindrical shape at the outer end of the mainspring, and inside the accommodating portion. There has been a method of adjusting the initial winding number at which the required torque is generated by moving the hooking position of the mainspring.

[0004]

However, in the case of the prior art, in order to give a predetermined initial number of turns to the mainspring, it was necessary to count the number of turns of the mainspring at the time of tightening. Therefore, a dedicated device is required, and it is difficult to assemble easily and quickly, which is not suitable for mass production. Furthermore, if there is variation in the torque characteristics of the mainspring,
If you set the initial number of turns only by the number of turns, the torque characteristics of the spring mechanism module output will vary, so
There was a problem in quality.

Further, a method of adjusting the initial number of turns of the mainspring mechanism module after installation has been proposed. However, this method requires specialized tools and techniques and is not suitable for mass production.

Further, when the mainspring is completely rewound due to accidental rewinding of the mainspring due to a failure or drop, or when the mainspring is completely rewound and the mainspring mechanism module is replaced, according to the conventional technique, the mainspring is again provided with a predetermined initial number of windings. It was very difficult to handle because it required specialized equipment, tools and techniques to give.

Moreover, in the prior art, the mainspring is damaged or deformed due to over-tightening, which not only affects the durability and characteristics of the mainspring, but also leads to a reduction in the reliability of the device itself equipped with the mainspring mechanism module. There was an occasion.

From such a background, there has been a demand for a mainspring mechanism module having a structure capable of easily giving a predetermined initial winding number of a mainspring.

SUMMARY OF THE INVENTION The present invention comprises a mainspring for accumulating mechanical energy, a mainspring accommodating portion for accommodating a mainspring, and a transmission means for exchanging mechanical energy between the mainspring and a drive mechanism. In addition, the mainspring mechanism module is provided with an initial number-of-winding means for regulating the number of turns so that the mainspring has a predetermined initial number of turns when the mainspring is incorporated.

That is, in order to incorporate the mainspring mechanism module into a drive mechanism such as a lid or door of a device or the like, it is necessary to incorporate the mainspring in a state in which an initial winding number is given. This is because it is necessary to provide an initial number of turns that satisfies the following conditions in order to realize stable movement over the entire drive section of the drive mechanism. That is, when the mainspring is rewound, the drive mechanism connected to the mainspring must always be in a state where the mainspring torque is applied. This allows
Torque is always applied in all drive sections of the drive mechanism, and stable movement can be realized. If the mainspring torque when rewinding is the minimum set torque,
If the torque generated when the mainspring is wound is set to the maximum set torque after satisfying this condition, the number of turns of the mainspring at this time becomes the initial number of turns. That is, the stable movement of the drive mechanism can be realized by incorporating it with the initial number of turns.

In the present invention as described above, the number of windings is regulated by the initial number of windings imparting means, so that the number of windings does not increase even if the mainspring is wound more than the initial number of windings. Therefore, it is possible to easily give a predetermined initial number of turns only by tightening the mainspring into an appropriate number of turns.

Therefore, when assembling the mainspring mechanism module into the drive mechanism, the step of setting the initial number of turns is not required, and a predetermined initial number of turns can be quickly obtained.
Productivity is improved and mass production is possible. Moreover, the winding device can quickly give the predetermined number of windings only by tightening the predetermined number of windings or more, so that it is possible to provide the mainspring mechanism module which is also advantageous in terms of cost.

Further, even if the torque specification of the mainspring is changed, it is not necessary to count the number of windings at the time of assembling. Therefore, if the shape of the mainspring mechanism module is the same, simply changing the initial number of windings and using the same assembling line. It becomes possible to incorporate products with various torque specifications. As a result, since products having different specifications can be incorporated using the same assembling line, it becomes possible to cope with small-lot production of a wide variety of products, and it is possible to provide a spring mechanism module that is cost effective.

Further, when the mainspring is completely rewound due to a sudden rewinding of the mainspring due to a failure, a drop or the like, or when the mainspring is completely rewound, conventionally, a special device, tool or technique is used for re-tightening. It was necessary to tighten the mainspring to a predetermined initial number of turns. According to the present invention, since the mainspring mechanism module is provided with the means for providing the initial number of turns, no special device or technique for setting the predetermined number of turns is required, and anyone can easily handle it. Therefore, it is possible to provide a mainspring mechanism module having excellent assemblability and maintainability.

Further, in the conventional structure, if the mainspring is over-tightened, an excessive load is applied to the outer end of the mainspring,
The mainspring could break or deform due to stress concentration. However, by providing the initial number-of-winding means of the present invention, the number of windings does not become tighter than the initial number of windings.

As described above, anyone can easily give a predetermined initial number of turns to the mainspring mechanism module, and since the method for incorporating the mainspring mechanism module is generalized, the mainspring mechanism module of the present invention is mounted. The reliability of the manufactured product is improved.

Further, in the mainspring mechanism module according to claim 1, the transmitting means is a rotating shaft rotatably held in the center of the mainspring accommodating portion, and an inner end of the mainspring is engaged with the transmitting means. The outer end of the mainspring may be engaged with the mainspring housing portion.

According to this structure, the mainspring mechanism module has a structure in which torque, force and speed are directly obtained from the rotating shaft which is the transmission means, as in a general motor. In the present invention, since the mainspring mechanism module can be handled in the same manner as a motor, it is possible to divert the conventional motor assembling technology. Further improve.

Furthermore, since the same mainspring mechanism module can be used for various drive mechanisms simply by changing the output wheel such as a gear or pulley attached to the transmission means, the mainspring mechanism module can be standardized. It is possible to provide products that are excellent in function and cost.

If the rotary shaft, which is the output means, is arranged so that it can be adjusted from the outside of the mainspring mechanism module, and the groove (minus, plus groove, etc.) for engaging a general-purpose tool is provided at the tip of the rotary shaft, the mainspring No need for a special device or tool when tightening, and anyone can easily tighten, and by using it together with the initial winding number giving means,
Since the number of windings is not required to be set, the installability is further improved.

Furthermore, since the transmission means is held by the mainspring accommodating portion, it is possible to realize a sealed structure that prevents foreign matter such as dust from entering the accommodating portion. Therefore, it is possible to suppress torque fluctuation and stress concentration due to adhesion of foreign matter on the surface of the mainspring, so that the characteristics and durability of the mainspring are improved. On the contrary, in order to reduce the friction between the mainsprings, it is possible to prevent the lubricating oil applied inside the mainspring housing from flowing out, so the energy loss due to the friction between the mainsprings is reduced and the durability is further improved. It is possible to let

Further, in the mainspring mechanism module according to claim 1 or 2, the initial winding number giving means is provided between the inner wall of the mainspring accommodating portion and the outer end of the mainspring. You can also

In this way, when the mainspring reaches the initial winding number, the initial winding number providing means provided between the inner wall of the mainspring container and the outer end of the mainspring separates the inner wall of the mainspring container and the outer end of the mainspring. That is, by setting the force for separating the outer end of the mainspring and the inner wall of the mainspring housing portion and the force when the mainspring has reached the initial winding number, the mainspring mechanism having an initial winding number providing means for obtaining the initial winding number only by tightening the winding. Module can be realized. In other words, an arbitrary initial winding number can be set by setting the force for separating the mainspring outer end and the mainspring housing inner wall, so that the initial winding number providing means can be obtained with a simple design. In other words, a versatile design according to a drive mechanism that incorporates the mainspring mechanism module is possible, the marketability is improved, and the required initial number of turns can be reliably provided.

Moreover, the initial winding number providing means can be realized with a relatively simple structure, and a space for installing the initial winding number is hardly required, so that the size can be reduced.

Further, in the mainspring mechanism module according to a third aspect of the present invention, the initial winding number imparting means is constituted by the mainspring accommodating portion having a plurality of grooves on an inner wall thereof and the mainspring having a protrusion engaging with the grooves. It may be characterized.

Usually, the protrusion formed on the outer end of the mainspring is in a state of being caught in a plurality of grooves provided on the inner wall of the mainspring accommodating portion. Therefore, if the mainspring is wound more than the initial number of turns, the protrusion is formed. The slipping out of the groove makes it possible to easily give the mainspring mechanism module an initial number of turns. In other words, by setting the force for the protrusion on the outer end of the mainspring to separate from the groove on the inner wall of the mainspring housing,
Since an arbitrary initial winding number can be set, it is possible to obtain the initial winding number giving means with a simple structure.

In addition, since the protrusions on the outer end of the mainspring can be easily formed by pressing or bending, the manufacturing can be easily selected according to the cost and the delivery date. Further, the function of the initial winding number imparting means can be satisfied even if the material of the mainspring accommodating portion is made of not only metal but also plastic material such as resin, so that it is possible to design in consideration of cost reduction regardless of material. . Further, by using oil-impregnated plastic, it is possible to realize a maintenance-free mainspring accommodating portion that can be lubricated.

Further, when the mainspring reaches the initial number of windings, a squeaking noise is made when the protrusion at the outer end of the mainspring is separated from the groove of the mainspring storage portion, so that the winding tightening state can be easily known. As a result, it is possible to provide a mainspring mechanism module with excellent embeddability.

Further, in the mainspring mechanism module according to a third aspect of the present invention, the initial winding number imparting means may be a slipping attachment mechanism including a friction member between the mainspring and the mainspring accommodating portion. .

With this configuration, when the mainspring exceeds the initial number of windings, the outer peripheral portion of the mainspring slides out of the inner wall of the mainspring housing portion through the friction member, so that the initial number of windings can be easily provided to the mainspring mechanism module. Furthermore, by setting the static frictional force of the friction member, it is possible to set an arbitrary initial winding number, so that it is possible to obtain the initial winding number providing means with a simple design.

Further, since the inner wall of the mainspring accommodating portion does not need to be fixed to fix the mainspring and the inner wall of the mainspring accommodating portion may have a simple circumferential shape, the mainspring accommodating portion can be formed by a simple turning process using a lathe or the like. Since it can be processed, a spring mechanism module with excellent processing cost and productivity can be provided.

Further, in the mainspring mechanism module according to claim 1 or 2, the initial winding number imparting means includes a fixing member for fixing the mainspring mechanism module to a device or the like, and the mainspring mechanism module. It may be arranged between them.

By doing so, even when the initial winding number giving means cannot be incorporated in the mainspring mechanism module, it can be arranged outside the mainspring mechanism module. Therefore, since the initial winding number providing means can be made large in design, sufficient strength can be obtained, and it is possible to correspond to the mainspring mechanism module that generates a large torque at the initial winding number.

Further, since the mainspring mechanism module can be made large in design, it is possible to provide a mechanism for finely adjusting the initial winding number. This allows you to have multiple drive mechanisms that require different initial windings,
The same mainspring mechanism module can be used by setting by fine adjustment. Therefore,
There is no need to create various standards, leading to cost reduction. In addition, it is possible to adjust the error of the mainspring output due to the difference in the mainspring lot and the friction amount of the drive mechanism to a certain level by fine adjustment, which leads to the improvement of the quality of the device equipped with the drive mechanism. Moreover, even if the driving force becomes small due to fatigue due to long-term use of the mainspring, it is possible to reset the driving force to the original value by making fine adjustments. Can provide products. Further, the driving force can be adjusted according to the taste of the user, so that the marketability is improved.

Further, in the mainspring mechanism module according to the first to sixth aspects, the initial winding number giving means may be an elastic body.

By doing so, the initial winding number giving means can be realized with a simple structure utilizing the elastic force and the frictional force of the elastic body. Further, if the elastic force can be adjusted, the static frictional force between the mainspring mechanism module and the fixing member can be adjusted, so that the mechanism for setting the initial number of turns can be easily realized.

Further, the mainspring mechanism module according to any one of claims 1 to 7 may further include a damper braking means.

Conventionally, when the drive mechanism is driven, it depends only on the force of the mainspring. Therefore, the speed at which the drive mechanism drives is the speed at which the mainspring rewinds, and the drive speed is high.
It was difficult to adjust this speed to an arbitrary speed. By using the damper braking means together as in the present invention, it becomes possible to obtain a braking force proportional to the rewinding speed of the mainspring, and it is possible to realize a smooth movement. In particular, when it is used for a cover or a lid of a small device, an added value such as a high-class feeling can be added to the device body.

Further, the load applied to the drive mechanism by the repeated rapid drive operation is reduced, and the durability can be improved. Particularly, if a rapid force is continuously applied to the initial number-of-winding imparting means, it may be damaged, and by attaching a damper, it serves as a cushioning material, leading to improvement in reliability.

When the power of the mainspring is extremely large,
There is a possibility that a user may be injured by pinching a finger or the like in the drive mechanism, but this can be prevented because smooth driving can be realized by the damper braking means.

When the damper braking means is attached,
The force applied to the drive mechanism requires a balance between the force generated from the mainspring and the force braked by the damper, and delicate force management is required. Therefore, the torque management of the mainspring becomes strict, but according to the present invention, an accurate initial winding number can be easily provided, so that the drive mechanism can be reliably driven.

Further, the present invention can be characterized by being a device using the mainspring mechanism module according to any one of claims 1 to 8.

Present portable devices are required to be multifunctional and downsized. Along with that, it was necessary to sacrifice operability in order to mount many functions in a small space. In order to solve this, a drive mechanism is often used, but since the installation space is small and the device body itself is small, the drive mechanism cannot be easily installed.

When the drive mechanism is incorporated in a small device,
A motor has been widely used as a driving power source. In the case of a motor, although it is easy to install, it is required to reduce the size and power consumption, and a power source that does not require electrical energy like the mainspring mechanism module in the present invention is required.

However, in consideration of the assembling property, the conventional mainspring drive mechanism had to have an assembling process in consideration of the initial winding number. However, as in the present invention, the initial winding number providing means is provided. The number of windings can be omitted, and workability and assembling are improved. Further, although a strict torque specification may be required as in the case of a motor, in the present invention, since the initial number of turns can be set, a device with high performance can be provided. In addition, since the operation of starting the operation is automatically performed by the power of the mainspring, it is possible to improve the operability of the device and also improve the merchantability.

Further, the mainspring mechanism module may be mounted on a device which is not electronically controlled, such as a toy.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] FIG. 1 shows a first embodiment of the present invention.
1 illustrates a portable device 1 including a drive mechanism 3 including a mainspring mechanism module 2 according to an embodiment.

FIG. 1 is an example, and any device may be used as long as it has a drive mechanism for driving a lid or a cover.
The portable device 1 includes a main body 10 including an input unit 11, a display unit 12, and a processing unit that does not display, and a cover 13 that is driven by the drive mechanism 3 and covers the input unit 11. Here, as what is driven by the drive mechanism 3,
It may be an input unit or a display unit.

The output wheel 21 of the mainspring mechanism module 2 is engaged and incorporated in the main body 10. Output car 2
1 may be anything as long as it can transmit power, and examples thereof include a gear, a pulley, and a cylindrical friction wheel. further,
The cover 13 includes a rack 8 so that the output car 21 is engaged with the rack 8.
1 is equipped. Here, the slide drive operation of the cover 13 is realized by the movement of the output wheel 21 and the rack 81, but the present invention is not limited to such a slide drive operation, and the output wheel 21 of the mainspring mechanism module 2 is not limited thereto.
By directly using to drive the lid, a rotary drive mechanism can also be realized. Further, in FIG. 1, the rotation axis of the output wheel 21 is arranged parallel to the surface of the cover 13, but it may be arranged so that the rotation axis of the output wheel 21 is perpendicular to the surface of the cover 13. . Further, the rack 81 is the main body 10.
Further, the mainspring mechanism module 2 may be attached to the cover 13.

The cover 13 is slidably mounted on the main body 10 and can be driven between A and B. When the upper end of the cover 13 is at the position A, the cover 13 is in a closed state. , B position when cover 1
3 is open. Further, when the cover 13 reaches the position B, the cover 13 is prevented from coming off.

FIG. 2 shows a perspective view of the mainspring mechanism module 2 incorporated in the portable device 1 of FIG. 1 when disassembled.

First, the structure of the mainspring mechanism module 2 shown in FIG. 2 will be specifically described. A gear, which is the output wheel 21, is engaged with a rotating shaft, which is the transmitting means 5 of the mainspring mechanism module 2, and the rotating shaft is rotatably held in the center of the upper lid 23 and the mainspring housing portion 24. Here, a gear is used as the output wheel 21, but a pulley or the like can be freely selected depending on the output target. In addition to the rack 81 shown in FIG. 1, when the output vehicle is a pulley, the belt meshing with the output vehicle 21 may be a belt corresponding thereto. Further, a rotary bearing, a sintered bearing, an oil-impregnated bearing, or oil is applied to the upper lid 23 that rotatably holds the transmission means 5 and the bearing portion 25 of the mainspring accommodating portion 24, and fluid is applied by non-diffusion treatment or the like. May be lubricated. By arranging the bearings in this way, it is possible to prevent an increase in load and a decrease in output due to friction.

Further, the mainspring 4 is accommodated in the mainspring accommodating portion 24, the inner end of the mainspring 4 is connected to the transmitting means 5, and the outer end is engaged with the initial winding number giving means 30. As shown in FIG. 2, an engaging portion between the inner end of the mainspring 4 and the transmitting means 5 has an inner hook portion 26 in the transmitting means 5, and the inner end of the mainspring 4 is sandwiched in the inner hook portion 26 so as to sandwich the mainspring. 4 and the transmission means 5 are engaged with each other.

In addition to this engagement method, the following method can be adopted. It is also possible to provide a pawl on the outer circumference of the rotating shaft which is the transmission means 5, and to make a hole at the inner end of the mainspring so that the hole and the pawl are hooked. At that time, if the cross-sectional shape of the rotary shaft is shaped so as to form an Archimedean spiral, the most preferable and stable torque can be extracted from the mainspring, and the theoretically uniform stress can be tightened without gaps, so stress concentration Generation can be suppressed and durability is improved.

Further, the spring may be made of any material, but when it is required that the material has excellent toughness and durability, it is desirable to use an alloy containing Cr, Co and Ni. For example, Co: 30-40%, Ni: 10
~ 20%, Cr: 8-15%, W: 3-5%, Mo: 3
~ 12%, C: less than 0.03%, Ti: 0.1 to 2%, M
A composition of n: 0.1 to 2%, Si: 0.1 to 2%, and Fe: balance is used.

The initial winding number imparting means 30 is in contact with the inner wall of the mainspring accommodating portion 24, and slips when a force of a certain level or more is applied. When the initial force is less than that, the initial winding number imparting means 30 and the spiral spring accommodating portion 24 have static friction. It remains engaged by force.

Further, the mainspring mechanism module 2 is fixed to the main body 10 in such a manner that the outer wall of the mainspring accommodating portion 24 is tightly fitted or sandwiched by screws or the like and held. Here, a collar may be provided in the mainspring housing portion 24, and the collar and the main body 10 may be fixed.

Next, the operation of the mainspring mechanism module 2 will be specifically described with reference to FIGS.

First, when the cover 13 is closed manually or the like, the linear movement of the cover 13 is converted into the rotational movement via the rack 81, and the rotational force is transmitted to the gear serving as the output wheel 21. This rotational force is transmitted to the mainspring 4 via the transmission means 5, and energy is accumulated in the mainspring 4. Cover 13
When completely closed, the switch mechanism (not shown)
The stopper 14 of the switch mechanism is engaged with the cover 13 to prevent the cover 13 from opening due to the rewinding of the mainspring 4.

When the cover 13 is opened, the switch 15 provided in the switch mechanism is pushed to interlock the stopper 14, and the cover 13 is disengaged from the stopper 14, and at the same time, the energy stored in the mainspring 4 is transmitted to the transmission means 5.
It is transmitted to the cover 13 via the output vehicle 21 and the rack 81, and is automatically opened by the mainspring energy.

Next, the winding of the mainspring mechanism module 2 will be specifically described.

As shown in FIG. 1, the drive section of the cover 13 is between AB. In order for the cover 13 to be driven by the mainspring, it is necessary to apply the torque required for driving to the cover 13 over the entire AB section. In order to do so, it is necessary to set the mainspring 4 so that the required torque is generated over the entire AB section.

FIG. 3 shows a torque curve showing the relationship between the torque of a mainspring and the number of turns. As the mainspring is tightened, the torque sharply increases with respect to the number of turns in the first section 12, but gradually becomes gentle, and the torque hardly increases with respect to the number of turns in the section 23, and finally the maximum torque point. Reach 4. When such a mainspring is used, since a stable operation can be performed by using a section in which torque fluctuation is small, a gentle section 23 is used in the torque curve. Further, the maximum torque generation region, that is, the maximum value in terms of stress also occurs just before winding, and the mainspring is deformed due to overwinding, which greatly affects the durability of the mainspring. Therefore,
In actual use, the point 3 after rewinding about 1 turn is used as the maximum set torque. That is, this maximum set torque is
The torque is generated at the point A, and is the torque generated at the initial winding number. Further, the minimum set torque is the torque generated at point B shown in FIG. Here, if the minimum set torque is too small, it becomes unstable when the cover 13 is opened, and the opening / closing operation is also unstable. Therefore, when setting the initial number of turns, it is desirable to determine the minimum setting torque and then set the maximum setting torque.

As described above, in order to assemble the mainspring mechanism module with the cover 13 closed, the number of turns at the maximum set torque of FIG.
That is, it is necessary to give the initial number of turns in advance.

Next, the initial winding number giving means of the present invention will be described. In the present invention, as shown in FIG. 2, the initial number of windings imparting means 3 which does not exceed the predetermined number of windings even if it is tightened more than a predetermined number of windings.
It has 0. That is, the mainspring mechanism module 2
When the initial winding number is given to, since the initial winding number giving means 30 and the inner wall of the mainspring accommodating portion 24 are engaged with each other up to a predetermined initial winding number, the transmission means 5 is turned to tighten the mainspring 4. On the other hand, when the number of turns exceeds the predetermined number of turns, that is, when the mainspring torque becomes equal to or more than the static frictional force, the initial number of turns imparting means 30
Regulates so that the mainspring does not slip beyond the inner wall of the mainspring accommodating portion 24 and the number of turns of the mainspring does not exceed that. As a result, just tighten the mainspring 4 without any special adjustment.
An initial winding number can be given to the mainspring mechanism module 2.

According to the first embodiment as described above, the following effects can be obtained.

That is, by the initial winding number giving means 30,
Since the number of windings is regulated, even if the mainspring 4 is tightened more than the initial number of windings to obtain the torque required for the operation of the cover 13,
The number of turns does not increase. Therefore, it is possible to easily give a predetermined initial number of turns only by tightening the mainspring 4 to an appropriate number of turns.

Therefore, when assembling the mainspring mechanism module into the drive mechanism, the step of counting the initial number of windings is not required, and a predetermined initial number of windings can be quickly obtained.
Productivity is improved and mass production is possible. Moreover, the winding device can quickly give the predetermined number of windings only by tightening the predetermined number of windings or more, so that it is possible to provide the mainspring mechanism module which is also advantageous in terms of cost.

Further, even if the torque specification of the mainspring is changed, it is not necessary to count the number of windings at the time of assembling. Therefore, if the shape of the mainspring mechanism module is the same, simply changing the initial number of windings and using the same assembling line. It becomes possible to incorporate products with various torque specifications. As a result, since products having different specifications can be incorporated using the same assembling line, it becomes possible to cope with small-lot production of a wide variety of products, and it is possible to provide a spring mechanism module that is cost effective.

Further, when the mainspring is completely rewound due to a sudden rewinding of the mainspring due to a failure, a drop or the like, or when the mainspring is completely rewound, conventionally, it is necessary to use a dedicated device, tool and technique for re-tightening. It was necessary to tighten the mainspring to a predetermined initial number of turns. According to the present invention, since the mainspring mechanism module is provided with the means for providing the initial number of turns, no special device or technique for setting the predetermined number of turns is required, and anyone can easily handle it. Therefore, it is possible to provide a mainspring mechanism module having excellent assemblability and maintainability.

Further, in the conventional structure, when the mainspring is over-tightened, an excessive load is applied to the outer end of the mainspring,
The mainspring could break or deform due to stress concentration. However, by providing the initial number-of-winding means of the present invention, the number of windings does not become tighter than the initial number of windings.

As described above, anyone can easily give a predetermined initial number of turns to the mainspring mechanism module, and since the method of incorporating the mainspring mechanism module is generalized, the mainspring mechanism module of the present invention is mounted. The reliability of the manufactured product is improved.

Further, as shown in FIG. 2, in the mainspring mechanism module 2, the transmission means 5 is connected to the mainspring accommodation section 24.
The mainspring holding portion 24 is rotatably held in the center and the main body 1
By fixing it to 0, the mainspring mechanism module 2 has a structure similar to a general motor. That is, the mainspring accommodating portion 24 corresponds to the case of the motor, and by fixing the mainspring accommodating portion 24, torque, force, and speed can be directly obtained from the rotating shaft 5, so that the mainspring mechanism module 2 is handled like a motor. Will be possible.

In the present invention as described above, the mainspring mechanism module has a structure in which torque, force and speed are directly obtained from the rotating shaft which is the transmission means 5, like a general motor. In the present invention, since the mainspring mechanism module 2 can be handled in the same manner as a motor, it is possible to divert the conventional motor incorporating technique, and by using it together with the initial winding number giving means 30 which does not require counting in setting the number of windings, The property is further improved.

Furthermore, by simply changing the output wheel 21 such as a gear or a pulley attached to the transmission means 5, the same mainspring mechanism module can be used for various drive mechanisms, so that the mainspring mechanism module can be standardized. It is possible to provide a product that is excellent in function and cost.

If the rotary shaft which is the output means 5 is arranged so that it can be adjusted from the outside of the mainspring mechanism module 2, and a groove (minus, plus groove, etc.) for engaging with a general-purpose tool is provided at the tip of the rotary shaft. In addition, anyone can easily tighten the mainspring 4 without the need for a special device or tool when tightening it, and by using it together with the initial number-of-winding means, the number of windings need not be set. Therefore, the assembling property is further improved.

Further, the transmission means 5 is attached to the mainspring housing portion 24.
Since the structure is held by, it is possible to realize a sealed structure that prevents foreign matter such as dust from entering the housing portion. Therefore, it is possible to suppress torque fluctuation and stress concentration due to adhesion of foreign matter on the surface of the mainspring, so that the characteristics and durability of the mainspring are improved. On the contrary, in order to reduce the friction between the mainsprings, it is possible to prevent the lubricating oil applied inside the mainspring housing from flowing out, so the energy loss due to the friction between the mainsprings is reduced and the durability is further improved. It is possible to let

Further, since the initial winding number imparting means 30 is provided between the outer end of the mainspring 4 and the inner wall of the mainspring accommodation section 24, when the mainspring 4 is wound more than a predetermined initial number of windings, the mainspring accommodation section 24 and the mainspring 4 are wound. Is separated.

In this way, when the mainspring 4 reaches the initial winding number, the initial winding number providing means 30 provided between the inner wall of the mainspring accommodation section 24 and the outer end of the mainspring 4 causes the inner wall of the mainspring accommodation section 24 and the outer end of the mainspring 4. Is separated. That is, by making the force for separating the outer end of the mainspring 4 and the inner wall of the mainspring accommodating portion 24 and the force when the mainspring 4 has reached the initial winding number, the initial winding number imparting means 30 for obtaining the initial winding number only by tightening the winding. It is possible to realize the mainspring mechanism module 2 having. In other words, by setting the force for separating the outer end of the mainspring 4 and the inner wall of the mainspring housing portion 24, an arbitrary initial number of windings can be set, so that the initial winding number providing means 30 can be obtained with a simple design. That is, a versatile design according to the drive mechanism in which the mainspring mechanism module 2 is incorporated can be realized, and the commercialability is improved, and the required initial number of turns can be surely given.

Moreover, the initial winding number imparting means 30 can be realized with a relatively simple structure, and a space for installing the initial winding number imparting means 30 is hardly required, so that the size can be reduced.

However, the position of the initial winding number giving means 30 is as follows.
The present invention is not limited to the outer end of the mainspring 4 and the inner wall of the mainspring accommodating portion 24, but may be between the output wheel 21 and the transmitting means 5, between the transmitting means 5 and the inner end of the mainspring 4, and the outer wall of the mainspring accommodating portion 24 as shown in the third embodiment. It may be installed between the fixing member 6 and the fixing member 6.

As a modified example of this embodiment, the spring mechanism module 2A having the structure shown in FIG. 4 can also be provided with the initial winding number giving means 30. In the present embodiment, as shown in FIG.
The mainspring holding portion 24 is rotatably held in the center and the main body 1
I took up the method of fixing to 0, but as shown in FIG.
The transmission means 5A is composed of a gear that is the output wheel 21A and a mainspring accommodating portion 24A.
, The fixed shaft 22 is fixed to the fixed bearing 84 of the fixing member 83, the inner end of the mainspring 4 is engaged with the fixed shaft 22, and the outer end of the mainspring 4 is engaged with the inner wall of the mainspring housing portion 24A to rotate the mainspring housing portion 24A. It is also possible to adopt a structure that makes it freely.
Here, the gear and the mainspring accommodating portion 24A may be integrally molded or may be separate bodies. Further, the mainspring housing portion 24A is provided with a rotary receiver 28 fixed to the fixed shaft 22 so as not to come off from the fixed shaft 22.

The initial winding number regulating means 30 is attached to the outer end of the mainspring 4, as in FIG. Further, the mainspring mechanism module 2A can be fixed to the main body 10 by passing a screw, a bolt or the like through the fixing hole 85 of the fixing member 83. Here, the fixing member 83 may be shared with the main body.

In this way, the mainspring mechanism module can be made smaller and thinner.

[Second Embodiment] FIG. 5 shows a second embodiment of the present invention.
3 illustrates a mainspring mechanism module 2B according to an embodiment.

As shown in FIG. 5, the initial winding number giving means 30
A is a rounded outer end which is the protrusion 31 of the mainspring 4A,
This is realized by utilizing the catching and friction between the curved portion 32 and the groove 33 on the inner wall of the mainspring housing portion 24B. Specifically, the protrusion 31 having the outer end portion of the mainspring 4A formed in a cylindrical shape, the curvature portion 32 having the outer end formed with a curvature smaller than the inner curvature of the mainspring accommodation portion 24B, and the inner wall of the mainspring accommodation portion 24B are provided. , The groove 3 that engages with the protrusion 31
3 is provided in plural. That is, when the protrusion 31 of the mainspring 4A is engaged with the plurality of grooves 33 provided on the inner wall of the mainspring housing portion 24B, the protrusion 31 slips out when a certain force is applied. With the number of turns, the initial number-of-turns imparting means 30A can be easily realized.

FIG. 6 shows the torque curve of the mainspring used in this embodiment. Assuming that the torque generated at the initial winding number is the maximum set torque, even if the winding is tightened for A or more, the winding will not be tightened for more than the maximum set torque, and the initial winding number imparting means 30A
It can be seen that the mainspring is given an initial winding number.

In the second embodiment as described above, the same actions and effects as those of the first embodiment can be obtained, and the following effects can be added.

Normally, the protrusion 31 formed on the outer end portion of the mainspring is in a state of being caught in the plurality of grooves 33 provided on the inner wall of the mainspring housing portion 24B. Therefore, if the mainspring is wound more than the initial number of turns. The protrusion 31 slips out of the groove 33 to allow the spring mechanism module 2B to be easily given an initial number of turns. In other words, an arbitrary initial winding number can be set by setting the force with which the protrusion 31 at the outer end of the mainspring separates from the groove in the inner wall of the mainspring housing portion, so that the initial winding number imparting means 30A can be obtained with a simple design. become.

In addition, since the protrusion 31 at the outer end portion of the mainspring can be easily formed by pressing or bending, manufacturing can be easily selected according to cost and delivery. Further, the function of the initial winding number imparting means can be satisfied even if the material of the mainspring accommodating portion is made of not only metal but also plastic material such as resin, so that it is possible to design in consideration of cost reduction regardless of material. . Further, by using oil-impregnated plastic, it is possible to realize a maintenance-free mainspring accommodating portion that can be lubricated.

Further, when the mainspring has reached the initial number of turns, the protrusion 31 at the outer end of the mainspring has the mainspring storage section 24.
Since a squeaking noise is heard when leaving the groove 33 of B, it is possible to easily know the winding tightened state, and it is possible to provide a spring mechanism module excellent in assembling.

As a modified example of this embodiment, a spring mechanism module having winding number limiting means 30B and 30C as shown in FIGS. 7 and 8 can be proposed.

In FIG. 7, a slipping attachment 34 is provided between the inner wall of the mainspring housing portion 24C and the mainspring 4B. That is, the slipping attachment 34 is designed to have a curvature smaller than the curvature of the inner wall of the mainspring housing portion 24C, and by applying a force that always tries to unwind the spring inside the mainspring housing portion 24C,
Friction is provided between the inner wall of the mainspring container 24C and the slipping attachment 34. The slipping attachment 34 has an outer hook 35 for hooking the mainspring 4B, and the force of the mainspring 4B is transmitted to the slipping attachment 34 via the outer hook 35. That is, the maximum set torque value can be finely set by adjusting the curved shape of the slipping attachment 34.

FIG. 8 shows the slipping attachment 34.
A does not directly contact the inner wall of the mainspring accommodating portion 24C, and the outermost periphery of the mainspring 4C is attached to the slipping attachment 34A.
The force is applied to spread the spring and bring it into contact with the mainspring housing portion 24C to generate friction, and thus the mainspring winding number regulating means 30.
C has been realized. In this case, the spring 4C and the slipping attachment 34A can be joined by spot welding without the need to use the press to form the outer hanging portion on the slipping attachment 34A.

By adopting the slipping attachment in this way, the following effects can be added.

With this configuration, when the mainspring exceeds the initial number of windings, the outer peripheral portion of the mainspring slides out of the inner wall of the mainspring housing portion through the friction member, so that the initial number of windings can be easily provided to the mainspring mechanism module. Furthermore, by setting the static frictional force of the friction member, it is possible to set an arbitrary initial winding number, so that it is possible to obtain the initial winding number providing means with a simple design.

Moreover, since the inner wall of the mainspring accommodating portion need not be processed to fix the mainspring and the inner wall of the mainspring accommodating portion may have a simple circumferential shape, the mainspring accommodating portion can be formed by a simple turning process using a lathe or the like. Since it can be processed, a spring mechanism module with excellent processing cost and productivity can be provided.

[Third Embodiment] FIG. 9 shows a third embodiment of the present invention.
3 shows a mainspring mechanism module 2C according to an embodiment.

Here, the initial winding number giving means 30D is provided between the mainspring mechanism module 2C and the fixing member 83A for fixing to the main body. Further, the initial winding number giving means 30D is engaged with the mainspring mechanism module 2C and is held by friction with the inner wall of the fixing member 83A. If a force above a certain level is applied, the initial winding number giving means 30D
A slip occurs between the fixing member 83A and the fixing member 83A, and in the case of less than that, the initial winding number imparting means 30D and the fixing member 83A are engaged by the static friction force. As a result, an initial winding number is given to the mainspring mechanism module.

The initial winding number giving means 30D and the fixing member 8
As a mechanism for holding between 3A, other than the mechanism using friction as shown in this embodiment, a modified example of this embodiment is shown in FIG.
1, a holding mechanism using elastic materials 88 and 88A as shown in FIG. 12 may be used.

Further, by disposing the initial winding number holding means on the outer periphery of the mainspring mechanism module, it becomes possible to mount a mechanism capable of adjusting the initial winding number.

FIG. 10 shows an example of the adjusting mechanism. The initial winding number imparting means 30D is engaged with the mainspring mechanism module 2C and is in frictional contact with the inner wall of the fixing member 83B. An adjusting gap 86 communicating from the outer wall to the inner wall is provided in a part of the fixing member 83B, and the width of the adjusting gap 86 can be adjusted by the adjusting screw 87. That is, by adjusting the adjustment gap 86, it is possible to adjust the amount of friction between the mainspring mechanism module 2C and the fixing member 83B, and as a result, the initial winding number can be finely adjusted.

In this third embodiment as well, the same actions and effects as those of the first embodiment can be obtained, and the following effects can be added.

By doing so, even when the initial winding number giving means cannot be incorporated in the mainspring mechanism module, it can be arranged outside the mainspring mechanism module. Therefore, since the initial winding number providing means can be made large in design, sufficient strength can be obtained, and it is possible to correspond to the mainspring mechanism module that generates a large torque at the initial winding number.

Further, since the mainspring mechanism module can be made large in design, it is possible to provide a mechanism for finely adjusting the initial winding number. This allows you to have multiple drive mechanisms that require different initial windings,
The same mainspring mechanism module can be used by setting by fine adjustment. Therefore,
There is no need to create various standards, leading to cost reduction. In addition, it is possible to adjust the error of the mainspring output due to the difference in the mainspring lot and the friction amount of the drive mechanism to a certain level by fine adjustment, which leads to the improvement of the quality of the device equipped with the drive mechanism. Moreover, even if the driving force becomes small due to fatigue due to long-term use of the mainspring, it is possible to reset the driving force to the original value by making fine adjustments. Can provide products. Further, the driving force can be adjusted according to the taste of the user, so that the marketability is improved.

As a modification of this embodiment, initial winding number giving means 30E and 30F as shown in FIGS. 11 and 12 can be proposed.

In FIG. 11, an elastic material 88 having a curvature smaller than that of the inner wall of the fixing member 83A is attached to the outer periphery of the mainspring mechanism module 2C, and the elastic force gives friction between the mainspring mechanism module 2C and the fixing member 83A. .
Therefore, the initial number of turns can be set by setting the maximum set torque to the same value as the elastic force and the static friction force.

In FIG. 12, a plurality of hooking grooves 89 are provided on the inner wall of the fixing member 83C, and an elastic member 88A having a protrusion that engages with the hooking grooves 89 is attached to the mainspring mechanism module 2C, and the elastic force thereof causes the mainspring mechanism module to move. Friction is to be applied between 2C and the fixing member 83C. Therefore, in order to set the initial number of turns as in the embodiment of FIG. 11, the maximum set torque may be the same as the elastic force and the static friction force.

The embodiment shown in FIG. 12 can also have a simple adjusting function. Since a plurality of hooking grooves 89 are provided, if the elastic member 88A is provided with a shape such that a thin rod can be hooked, the initial winding number can be simplified by moving the position where the protrusions are engaged with each other after tightening the mainspring. It becomes possible to adjust it.

[Fourth Embodiment] FIG. 13 shows a mainspring mechanism module 2D according to a third embodiment of the present invention.

An example in which the damper braking means 70 is attached to the embodiment shown in FIG. 2 will be described here. First, the structure will be described. The damper case 73 that is sufficiently filled with the fluid material 75 and the braking plate 7 that is dipped in the damper case 73.
2, and a damper braking means 70 including a damper lid 71 is attached below the mainspring housing portion 24.
The rotating shaft which is the transmitting means 5 and the braking plate shaft 74 are engaged with each other, and when the transmitting means 5 rotates, the braking plate 72 also rotates and the braking plate 72 traverses through the fluid substance 75 to generate a braking force.

A high-viscosity fluid substance 75 such as silicone oil is immersed in the damper case 73, and the force generated by the braking plate 72 traversing the fluid substance 75 is utilized according to the number of revolutions. Has gained a braking force. Here, as the fluid substance 75, in addition to silicone oil,
A high-viscosity viscous fluid or gas can be used. Further, in the damper case 73, in addition to the fluid substance,
A braking force using an electromagnetic brake or a wind turbine whose speed is increased may be used.

The operation when the mainspring mechanism module 2D of this embodiment is incorporated will be described below with reference to FIGS. 1 and 13.

When the cover 13 is closed, the rotational energy is transmitted to the transmission means 5 via the rack 81 and the gear 21. The rotational energy is transmitted to and accumulated in the mainspring 4, and at the same time, transmitted to the damper braking means 70, which serves as a load when the cover 13 is closed. On the other hand, cover 1
When opening 3, the energy of the spring 4 is transmitted to the rotary shaft 5, and at the same time, a braking force is generated from the damper braking means 70 according to the opening speed. As a result, cover 1
3 opens smoothly at a constant speed.

Here, the damper braking means 70 does not necessarily have to be arranged below the mainspring storage section 24. As long as it can be handled as one unit, it may be on the mainspring storage portion or may be arranged so as not to overlap in a plane. Further, the braking plate 72 and the braking plate shaft 72 may have an integrated structure.

In the fourth embodiment as described above, the same actions and effects as those of the first embodiment can be obtained, and the following effects can be added.

Conventionally, when the drive mechanism is driven, it depends only on the power of the mainspring. Therefore, the speed at which the drive mechanism drives is the speed at which the mainspring rewinds, and the drive speed is high.
It was difficult to adjust this speed to an arbitrary speed. By using the damper braking means together as in the present invention, it becomes possible to obtain a braking force proportional to the rewinding speed of the mainspring, and it is possible to realize a smooth movement. In particular, when it is used for a cover or a lid of a small device, an added value such as a high-class feeling can be added to the device body.

However, in order to realize the above movement, it was necessary to strictly manage the number of turns of the mainspring 4. For example, if the drive distance AB of the cover shown in FIG. 1 is 4 cm, the speed at which the cover looks smooth for about 0.3 seconds,
If it is 0.1 seconds earlier than this, it does not seem to be a smooth drive. If 0.1 second is late, it is too late this time to give the user an unpleasant feeling. Thus, by mounting the damper braking means 70, strict winding number control of the mainspring was required. However, as shown in the present embodiment, by providing the mainspring winding number regulation means 30, it becomes possible to obtain a predetermined torque easily and accurately, and to realize a smooth drive mechanism without managing the number of windings. became.

Further, the load applied to the drive mechanism by repeating the abrupt drive operation is reduced, and the durability can be improved. Particularly, if a rapid force is continuously applied to the initial number-of-winding imparting means, it may be damaged, and by attaching a damper, it serves as a cushioning material, leading to improvement in reliability.

When the power of the mainspring is extremely large,
There is a possibility that a user may be injured by pinching a finger or the like in the drive mechanism, but this can be prevented because smooth driving can be realized by the damper braking means.

When a damper braking means is attached,
The force applied to the drive mechanism requires a balance between the force generated from the mainspring and the force braked by the damper, and delicate force management is required. Therefore, the torque management of the mainspring becomes strict, but according to the present invention, an accurate initial winding number can be easily provided, so that the drive mechanism can be reliably driven.

[Fifth Embodiment] FIGS. 14, 15, and 16.
In the figure, there are shown devices 1, 1A and 1B in which the mainspring mechanism module 2 according to the fifth embodiment of the present invention is incorporated.

FIG. 14 is a cover 13 that includes an input unit 11, a display unit 12, and a processing unit that does not display, and covers the input unit 11.
1 shows a portable device 1 composed of By manually sliding the cover 13, the input unit 1
By covering 1 and pressing a switch or the like, the cover 13 is opened by the power of the mainspring, and the state shown in the drawing is obtained. Here, the display unit 12 may be covered by the cover 13. Further, the cover 13 may be equipped with an input unit, a display unit, and the like.

FIG. 15 shows a portable device 1A in which a driving body 13A having an input section 11A mounted thereon pops out of a main body 10A. By manually sliding the driving body 13A, the driving body 13A fits inside the main body 10A, and by pressing a switch or the like, the driving body 13A pops out of the main body 10A by the force of the mainspring, and the state shown in the drawing is obtained. Further, not only the input section, but also the display section, the camera, etc. may pop out. Moreover, an input unit or the like may be mounted on the main body.

FIG. 16 shows an example in which the rotational force output from the mainspring mechanism module 2 is used as it is to drive the lid 13B. The lid 13B is manually closed, and the lid 13B is opened by the power of the mainspring by a switch or the like, and the state shown in the drawing is obtained.

Also in the fifth embodiment as described above, the same operation and effect as those of the first embodiment can be added.

The current portable equipment is required to be multifunctional and downsized. Along with that, it was necessary to sacrifice operability in order to mount many functions in a small space. In order to solve this, a drive mechanism is often used, but since the installation space is small and the device body itself is small, the drive mechanism cannot be easily installed.

When incorporating the drive mechanism into a small device,
A motor has been widely used as a driving power source. In the case of a motor, although it is easy to install, it is required to reduce the size and power consumption, and a power source that does not require electrical energy like the mainspring mechanism module in the present invention is required.

However, in consideration of the assembling property, the conventional mainspring drive mechanism had to have an assembling step in consideration of the initial winding number. However, by providing the initial winding number providing means as in the present invention. The number of windings can be omitted, and workability and assembling are improved. Further, although a strict torque specification may be required as in the case of a motor, in the present invention, since the initial number of turns can be set, a device with high performance can be provided. In addition, since the operation of starting the operation is automatically performed by the power of the mainspring, it is possible to improve the operability of the device and also improve the merchantability.

Further, the mainspring mechanism module may be mounted on a device which is not electronically controlled, such as a toy.

Further, as the shape of the mainspring, a spiral spring may be used, or a contact type constant torque mainspring may be used. The thickness and width of the mainspring may be not only uniform over the entire length but also continuously changing.

[0133]

As described above, according to the present invention,
By equipping the mainspring mechanism module with the initial winding number providing means, the initial winding number at which a predetermined torque is generated can be easily and accurately generated by simply tightening the mainspring without counting the winding winding number at the time of installation. Can be given.
