Detailed description of the invention
(the basic opinion as the present invention)
The present inventors are in order to solve above-mentioned existing problem, after repeatedly studying intensively, draw following opinion.
First, the present inventors have carried out the investigation relevant with existing air conditioner. At Figure 12, Tu13Zhong, represent the structure of existing air conditioner 100. Figure 12, Figure 13 represent the Zhou Biantu of the supporting end of the blade of wind deflection up and down 101 in air conditioner 100. As shown in Figure 12 and Figure 13, existing air conditioner 100 includes upper and lower wind deflection blade 101, blow-off outlet 102, torsion-coil spring (torsioncoilspring) 103, supporting axle 104 and main body 105. Figure 13 represents in air conditioner 100, and upper and lower wind deflection blade 101 is in the state of " closed position " of closing blow-off outlet 102.
As shown in Figure 12 and Figure 13, in existing air conditioner 100, as the forcing unit on the direction (being counterclockwise in fig. 13) close blow-off outlet 102, upper and lower wind deflection blade 101 exerted a force, it is provided with torsion-coil spring 103. Torsion-coil spring 103 is fixed in main body 105, and links with the supporting axle 104 as the axle supporting upper and lower wind deflection blade 101. Supporting axle 104 is the center of rotation of upper and lower wind deflection blade 101. Supporting axle 104 is supported on main body 105 with the state that can rotate by axle.
Closed position shown in fig. 13, is in the position of roughly the same height as the supporting axle 104 of center of rotation of upper and lower wind deflection blade 101 and the center of gravity 106 of upper and lower wind deflection blade 101. Now, about the mutual horizontal direction of supporting axle 104 and center of gravity 106 apart from the longest. In this state, the torque T a (in fig. 13 for clockwise arrow) of supporting axle 104 it is applied to because of the deadweight of upper and lower wind deflection blade 101 also for maximum. In fig. 13, with such when upper and lower wind deflection blade 101 is in the closed position, the form that the torque T a being applied to supporting axle 104 because of the deadweight of upper and lower wind deflection blade 101 is maximum is that example illustrates.
When upper and lower wind deflection blade 101 is in rotary moving in the direction opening blow-off outlet 102 from the closed position shown in Figure 13, namely in fig. 13 by support rotate clockwise centered by axle 104 time, the center of gravity 106 of upper and lower wind deflection blade 101 in the horizontal direction relative to supporting axle 104 close. Thus, the torque T a being applied to supporting axle 104 because of the deadweight of upper and lower wind deflection blade 101 also tapers into.
So, in rotary moving downwards from closed position with upper and lower wind deflection blade 101, the torque T a being applied to supporting axle 104 because of the deadweight of upper and lower wind deflection blade 101 diminishes. Finally, when upper and lower wind deflection blade 101 has rotated to downwards about 90 degree from closed position, torque T a is almost 0.
On the other hand, the active force that produced by torsion-coil spring 103 and be applied to the reactive torque Tb (in fig. 13 for counterclockwise) of supporting axle 104, in rotary moving in the direction opening blow-off outlet 102 from closed position with upper and lower wind deflection blade 101 and become big. Rotating with the supporting axle 104 of upper and lower wind deflection blade 101, becoming greatly from the deformation of original state of torsion-coil spring 103, the power that will return to origin-location becomes big.
Represent the relation of this torque T a and Tb in fig. 14. In fig. 14, transverse axis is the open angle (unit: degree) of the self closing position of upper and lower wind deflection blade 101, and the longitudinal axis is moment of torsion (unit: g cm). For the open angle of transverse axis, for closed position is set to 0 degree, the situation that maximum open position is 120 degree illustrates. Lines 1 represent the torque T a being applied to supporting axle 104 because of the deadweight of upper and lower wind deflection blade 101. Lines 2 represent the reactive torque Tb being applied to supporting axle 104 because of the active force of torsion-coil spring 103. Lines 3 represent the difference (synthesis moment of torsion) of the moment of torsion of lines 1 and the moment of torsion of lines 2. These lines 3 represented as the difference of lines 1 and lines 2 represent the torque T c (hereinafter referred to as distortion torque T c) of the reason of the distortion becoming upper and lower wind deflection blade 101. Although not representing in Figure 12, Figure 13, but the end of the opposite side contrary with the side being configured with torsion-coil spring 103 of supporting axle 104 (one end of supporting axle 104) is fixed in the rotating shaft of the motor driving upper and lower wind deflection blade 101. By the internal structure of motor, the rotating shaft of motor resists above-mentioned torque T a, and upper and lower wind deflection blade 101 is maintained at the open position of regulation. On the other hand, in the end (other end of supporting axle 104) of the side being configured with torsion-coil spring 103 of supporting axle 104, the moment of torsion resisting above-mentioned torque T a is only above-mentioned torque T b. Therefore, the supporting axle 104 of upper and lower wind deflection blade 101, the moment of torsion of torque T a that opposing causes because of the deadweight of upper and lower wind deflection blade 101, in the side (another side) linked from torsion-coil spring 103 be different with the side (end side) that the rotating shaft of motor links. That is, the above-mentioned torque T c produced in the side being configured with torsion-coil spring 103 is the moment of torsion of the reason becoming the distortion of upper and lower wind deflection blade 101. Particularly descend wind direction deflecting blade 101 in the side being configured with torsion-coil spring 103 in the closed position, an upper, compared with the side being configured with motor, it is easier to be positioned at the direction opening blow-off outlet 102.
As shown in the lines 3 of Figure 14, the distortion torque T c in upper and lower wind deflection blade 101, the open angle at upper and lower wind deflection blade 101 is 0 when being approximately 45 degree, and leaves with open angle from 45 degree and become big. Especially, when the open angle of upper and lower wind deflection blade 101 is close to 0 degree or when being more than substantially 90 degree, the distortion torque T c of upper and lower wind deflection blade 101 becomes big.
When there is the distortion torque T c of this upper and lower wind deflection blade 101, when upper and lower wind deflection blade 101 opening and closing, when upper and lower wind deflection blade 101 closes blow-off outlet, there is the situation producing gap between upper and lower wind deflection blade 101 and blow-off outlet 102. Namely, it is possible to blow-off outlet 102 can not be closed with good precision.
In consideration of it, the present inventors have studied intensively. Its result draws, by being applied to the change of the torque T a of supporting axle 104 according to the deadweight because of upper and lower wind deflection blade 101, torque T b to be applied to supporting axle by the active force of torsion-coil spring is set in the way of changing too, it is possible to effectively cancel out each other torque T a, Tb, reduce distortion torque T c.

Additionally, at the distance between centers of connecting portion 12 (supporting axle A) and jut 9c than the position of connecting portion 12 (supporting axle A) and the distance between centers length of roller 13, be provided with jut 9c.
Torsion-coil spring 11 is the example producing the force application part for the active force reducing the moment of torsion caused because of the deadweight of upper and lower wind deflection blade 2. Torsion-coil spring 11 configures in the way of contacting with the roller 13 of rotary part 10, and is fixed on lid 9a (jut 9c). Torsion-coil spring 11 from the connecting portion 12 of the center of rotation as rotary part 10 in the position of radial disbalance, contact with rotary part 10. Torsion-coil spring 11 is configured to, by rotary part 10 is exerted a force, it is possible to via rotary part 10 and supporting axle A, upper and lower wind deflection blade 2 is exerted a force.

The part that 2nd extension 16b extends from the other end with the 1st extension 16a opposite side, spire 15, and it is fixed on lid 9a. According to this structure, become the fulcrum of torsion-coil spring 11 as spire the 15 and the 2nd extension 16b being fixed on the part covering 9a.
It follows that for the action of distortion dampening mechanism of above-mentioned air conditioner 1 and effect, use Fig. 7-Fig. 9 to illustrate.
Fig. 7 represents that upper and lower wind deflection blade 2 closes the state (closed position) of blow-off outlet 4. Fig. 8 represents that upper and lower wind deflection blade 2 have rotated downwards the state of about 45 degree from closed position. Fig. 9 represents that upper and lower wind deflection blade 2 have rotated downwards the state of about 90 degree from closed position, and namely wind deflection blade 2 is opened to the state (maximum open position) of bottom up and down.
As it is shown in fig. 7, when upper and lower wind deflection blade 2 is in the closed position, the height and position of the center of gravity 2g of upper and lower wind deflection blade 2 is roughly the same with the height and position of the supporting axle A of the center of rotation as upper and lower wind deflection blade 2. Now, mutual for center of gravity 2g and supporting axle A horizontal direction distance D1 is substantially maximum. Thus, the torque T 1 of upper and lower wind deflection blade 2 (supporting axle A) it is applied to because of the deadweight G of upper and lower wind deflection blade 2 also for substantially maximum.
On the other hand, in distortion dampening mechanism 7, by torsion-coil spring 11, rotary part 10 is exerted a force, along the direction (reverse direction of torque T 1) reducing torque T 1, rotary part 10 is exerted a force. Specifically, the 1st extension 16a of torsion-coil spring 11 contacts with the roller 13 of rotary part 10, and pressing roller 13. Thus, rotary part 10 is given the external force S1 in the direction shown in Fig. 7.
As it is shown in fig. 7, the 1st extension 16a contacts with roller 13 at contact position P1, and contact with the contact angle of regulation relative to rotary part 10. Here contact angle refers to, based on the angle in the 1st extension 16a contacted with rotary part 10 direction extended or the direction of the external force S1 effect vertical with the direction. By this external force S1 is imparted to rotary part 10, in the rotary part 10 being center of rotation with connecting portion 12, produce the torque T 2 reverse with the torque T 1 shown in Fig. 7. By producing this torque T 2 in rotary part 10, it is possible to make torque T 2 act on the supporting axle A that the connecting portion 12 with rotary part 10 links, so that the torque T 1 caused because of the deadweight of upper and lower wind deflection blade 2 reduces (counteracting).
Being set as in the present embodiment, when upper and lower wind deflection blade 2 is in the closed position, the torque T 2 as the active force of distortion dampening mechanism 7 generation is substantially maximum. Specifically, in the state shown in Fig. 7, torsion-coil spring 11 and rotary part 10 being configured to, the center of the direction of the external force S1 of the roller 13 of rotary part 10 and the connecting portion 12 (supporting axle A) from rotary part 10 of being applied to is substantially vertical (angle [alpha] 1 mutually formed is about 90 degree) towards the direction L1 of roller 13. By this configuration, the force component in the direction of rotation of rotary part 10 that torsion-coil spring 11 gives rotary part 10 is roughly equal with external force S1. Thus, the torque T 2 making the external force S1 supporting axle A being applied to upper and lower wind deflection blade 2 is substantially maximum.
So, in the air conditioner 1 of present embodiment, the torque T 2 in the direction of the torque T 1 being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 and the reduction torque T 1 produced by distortion dampening mechanism 7 is all configured to, and is substantially maximum when upper and lower wind deflection blade 2 is in the closed position. By this setting, it is possible to effectively cancel out torque T 1 and torque T 2. Thereby, it is possible to reduce the moment of torsion in the distortion produced in upper and lower wind deflection blade 2 being configured with distortion dampening mechanism 7 side place, it is possible to suppress the distortion of upper and lower wind deflection blade 2.
Also it is set as follows in the present embodiment, namely when upper and lower wind deflection blade 2 is in the closed position, torque T 2 larger than torque T 1 (using Figure 10 to describe below). By this setting, when upper and lower wind deflection blade 2 closes blow-off outlet 4, it is possible to close blow-off outlet 4 with good precision more reliably.
It follows that be in the state of the position opening predetermined angular (being 45 degree in the present embodiment) from closed position for the blade of wind deflection up and down 2 shown in Fig. 8, illustrate.
In the state shown in Fig. 8, upper and lower wind deflection blade 2 is in rotary moving downwards from closed position, and thus the center of gravity 2g of wind deflection the blade 2 and mutual horizontal direction distance D2 as the supporting axle A of center of rotation becomes shorter than above-mentioned D1 up and down. Thus, it is applied to the torque T 3 of supporting axle A because of the deadweight G of upper and lower wind deflection blade 2, diminishes compared with the torque T 1 under the state shown in Fig. 7.
On the other hand, in distortion dampening mechanism 7, rotating with upper and lower wind deflection blade 2, the rotary part 10 linked with upper and lower wind deflection blade 2 also rotates to equidirectional (being clockwise in fig. 8) centered by connecting portion 12 (supporting axle A). Thus, the change in location of the roller 13 of rotary part 10, and the contact position P2 that the 1st extension 16a of torsion-coil spring 11 contacts with roller 13 is also from above-mentioned contact position P1 change, and contact angle also changes.
Now, as shown in Figure 8, from torsion-coil spring 11 relative to roller 13, give in the direction vertical with the bearing of trend of the 1st extension 16a and have external force S2. Here, the contact position P1 of the state shown in contact position P2 and Fig. 7 that torsion-coil spring 11 contacts with rotary part 10 compares, farther from spire the 15 and the 2nd extension 16b of the fulcrum as torsion-coil spring 11, therefore, this external force S2 is larger compared with external force S1. On the other hand, the direction of this external force S2, relative to the direction L2 of the centrally directed roller 13 from connecting portion 12 (supporting axle A), forms the predetermined angular �� 2 less than 90 degree. Therefore, to give the force component F in the direction of rotation of rotary part 10 of rotary part 10 less than external force S2 for torsion-coil spring 11. Thus, external force S2 the torque T 4 of the supporting axle A being applied to upper and lower wind deflection blade 2 is also little than the torque T 2 under the state shown in Fig. 7.
So, in the present embodiment, by the rotation of upper and lower wind deflection blade 2, the torque T 3 being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 diminishes, in response to this, the mode that also diminishes of torque T 4 for distortion dampening mechanism 7 generation reducing torque T 3 is set. By this setting, it is possible to effectively reduce torque T 3 by torque T 4, therefore, it is possible to suppress the distortion at the blade of wind deflection up and down 2 being configured with distortion dampening mechanism 7 side place.
It follows that be in the state of maximum open position for the blade of wind deflection up and down 2 shown in Fig. 9, illustrate.
In the state shown in Fig. 9, upper and lower wind deflection blade 2 is in rotary moving from the side further downward of the state shown in Fig. 8, thus rotate substantially 90 degree from closed position. Here, the mutual horizontal direction distance substantially 0 of the center of gravity 2g and supporting axle A as center of rotation of upper and lower wind deflection blade 2. Thus, the moment of torsion too substantially 0 of the supporting axle A of upper and lower wind deflection blade 2 it is applied to because of the deadweight G of upper and lower wind deflection blade 2.
On the other hand, in distortion dampening mechanism 7, rotating with upper and lower wind deflection blade 2, the rotary part 10 linked with upper and lower wind deflection blade 2 also rotates to equidirectional (being clockwise in fig .9) centered by connecting portion 12 (supporting axle A). Thus, the 1st extension 16a of torsion-coil spring 11 contacts with roller 13 contact position P3 and its contact angle also change. Now, as it is shown in figure 9, from torsion-coil spring 11 relative to roller 13, give along the direction vertical with the bearing of trend of the 1st extension 16a and have external force S3. Therefore, the contact position P2 of the state shown in contact position P3 and Fig. 8 that torsion-coil spring 11 contacts with rotary part 10 compares, farther from spire the 15 and the 2nd extension 16b of the fulcrum as torsion-coil spring 11, therefore this external force S3 is larger than external force S2. On the other hand, the direction of this external force S3 becomes almost parallel (angle mutually formed substantially 0 degree) with the direction L3 of the centrally directed roller 13 from connecting portion 12 (supporting axle A). Therefore, torsion-coil spring 11 gives the force component in the direction of rotation of rotary part 10 of rotary part 10 substantially 0. Thus, external force S3 is applied to the moment of torsion of the supporting axle A of upper and lower wind deflection blade 2 also substantially 0 via rotary part 10.
So, in the present embodiment, it is applied to the moment of torsion substantially 0 of supporting axle A because of the deadweight G of upper and lower wind deflection blade 2, in response to this, is also substantially set in the way of 0 by the moment of torsion reducing moment of torsion that produced by distortion dampening mechanism 7. By this setting, it is possible to suppress the distortion of upper and lower wind deflection blade 2 with good precision.
Illustrate the curve chart representing above-mentioned torque relationship in Fig. 10.
In Fig. 10, transverse axis is set to the open angle (degree) of the self closing position of upper and lower wind deflection blade 2, and the longitudinal axis is set to moment of torsion (g cm). Lines 4 represent the moment of torsion (comprising T1, T3) being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2. Lines 5 represent the reactive torque (comprising T2, T4) being applied to supporting axle A by the active force of torsion-coil spring 11. Lines 6 are the differences of moment of torsion 4 and moment of torsion 5, and it represents the synthesis moment of torsion of respective moment of torsion. These lines 6 represent " the distortion moment of torsion " of upper and lower wind deflection blade 2.
As shown in the lines 4 of Figure 10, the open angle of upper and lower wind deflection blade 2 is more big, and the moment of torsion being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 is more little. On the other hand, as shown in the lines 5 of Figure 10, the moment of torsion (making the moment of torsion that the moment of torsion being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 reduces) being applied to supporting axle A by the active force of torsion-coil spring 11 is set as similarly, the open angle of upper and lower wind deflection blade 2 is more big, and this moment of torsion is more little. Thus, as shown in lines 6, no matter the open angle of upper and lower wind deflection blade 2 is how, can both by be applied to the distortion moment of torsion of upper and lower wind deflection blade 2 close to 0 in the way of effect. According to this structure, it is possible to suppress the distortion caused because of the deadweight G of upper and lower wind deflection blade 2 with good precision.
As shown in the lines 5 of Figure 10, at least it is set as follows: compared with when being in maximum open position (90 degree) with upper and lower wind deflection blade 2, during upper and lower wind deflection blade 2 (0 degree) in the closed position, the active force of torsion-coil spring 11 moment of torsion force component in the direction of rotation of rotary part 10 of rotary part 10 (torsion-coil spring 11 give) being applied to supporting axle A is bigger. Thus, different from existing air conditioner, it is possible to suppress the distortion (lines 2 with reference to Figure 14) caused because of the deadweight G of upper and lower wind deflection blade with good precision.
In addition, it is set as follows: when upper and lower wind deflection blade 2 (0 degree) in the closed position, with because of upper and lower wind deflection blade 2 deadweight G and be applied to supporting axle A moment of torsion (lines 4) compared with, torsion-coil spring 11 force component (lines 5) in the direction of rotation of rotary part 10 giving rotary part 10 is bigger. That is, when upper and lower wind deflection blade 2 is in the closed position, the value of the moment of torsion shown in lines 6 is just. By being configured so that rotary part 10 and torsion-coil spring 11, it is possible to do not produce the mode in gap when above lower wind direction deflecting blade 2 is in the closed position at blow-off outlet 4, utilize upper and lower wind deflection blade 2 to close blow-off outlet 4 with better precision.
It addition, in order to make the torque relationship shown in Figure 10 set up, in the distortion dampening mechanism 7 of present embodiment, with the relation of the position of regulation and angle configuration rotary part 10 and torsion-coil spring 11. Specifically, as Figure 7-9, the rotation of accompanying rotation parts 10, the contact angle change of rotary part 10 and torsion-coil spring 11, thus make to be given force component (F with reference to Fig. 8) change in the direction of rotation of rotary part 10 of rotary part 10 by torsion-coil spring 11. Rotary part 10 and torsion-coil spring 11 is configured in the way of producing this change. So, by utilizing the relation of the change of the contact angle of rotary part 10 and torsion-coil spring 11, it is possible to realize distortion dampening mechanism 7 with more easy structure.
Further, in the distortion dampening mechanism 7 of present embodiment, the rotation of accompanying rotation parts 10, the position that torsion-coil spring 11 contacts with rotary part 10 from torsion-coil spring 11 fulcrum (spire the 15 and the 2nd extension 16b) more away from, the power (S1-S3) that torsion-coil spring 11 gives rotary part 10 is more big. On the other hand, in the way of the force component (F with reference to Fig. 8) in the direction of rotation of rotary part 10 in this power (S1-S3) diminishes, configure torsion-coil spring 11. So, by being set in the way of giving the increase/reduction of the force component (F) in the direction of rotation of rotary part 10 in the increase/reduction of the power (S1-S3) of rotary part 10 and this power by torsion-coil spring 11 and reversing each other, it is possible to realize distortion dampening mechanism 7 with more easy structure.
Additionally, in the distortion dampening mechanism 7 of present embodiment, use torsion-coil spring 11 as the force application part that rotary part 10 is exerted a force. So, by using torsion-coil spring as force application part, it is possible to realize distortion dampening mechanism 7 with more easy structure.
Additionally, in the distortion dampening mechanism 7 of present embodiment, in rotary part 10, roller 13 is arranged on the position contacted with torsion-coil spring 11. By arranging this roller 13, it is possible to suppress the abrasion and the damage that cause due to the contact of rotary part 10 and torsion-coil spring 11.
As it has been described above, the air conditioner 1 of present embodiment includes: wind deflection blade 2, distortion dampening mechanism 7, motor 8 and force application part 11 (torsion-coil spring 11) up and down. Upper and lower wind deflection blade 2 has supporting axle A, by support axle A central rotation, between closed position and the open position opening blow-off outlet 4 of closing blow-off outlet 4, deflecting wind direction in the vertical direction. Distortion dampening mechanism 7 is connected with the other end of the supporting axle A of upper and lower wind deflection blade 2, it is suppressed that the distortion caused because of the deadweight G of upper and lower wind deflection blade 2. Distortion dampening mechanism 7 includes rotary part 10. Rotary part 10 is connected with the other end of supporting axle A, and rotates with the rotation of supporting axle A. Motor 8 is connected with one end of the supporting axle A of upper and lower wind deflection blade 2, is driven in the way of making supporting axle A rotation. Force application part 11 is contacting from the center of rotation eccentric position of rotary part 10 with rotary part 10, and on the direction making the moment of torsion being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 reduce, rotary part 10 is exerted a force. Force application part 11 gives the force component F in the direction of rotation of rotary part 10 of rotary part 10 and is configured to, and force component F when rotary part 10 is in the position corresponding with the closed position of upper and lower wind deflection blade 2 is bigger than the force component F that rotary part 10 is in during the position corresponding with the maximum open position of upper and lower wind deflection blade 2.
In general air conditioner, it is applied to the moment of torsion of supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 mostly, maximum when upper and lower wind deflection blade 2 is in the closed position, minimum when upper and lower wind deflection blade 2 is in maximum open position. Given this, the force component F in the direction of rotation of rotary part 10 that force application part 11 gives rotary part 10 is set as, force component F when rotary part 10 is in the position corresponding with the closed position of upper and lower wind deflection blade 2 is bigger than this force component F that rotary part 10 is in during the position corresponding with the maximum open position of upper and lower wind deflection blade 2. By this setting, the open angle according to upper and lower wind deflection blade 2, it is possible to effectively reduced the moment of torsion being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 by the active force of force application part 11. Thereby, it is possible to suppress the distortion caused because of the deadweight G of upper and lower wind deflection blade 2 with good precision.
Additionally, present embodiment for suppressing the distortion dampening mechanism 7 of distortion caused because of the deadweight G of upper and lower wind deflection blade 2 to include rotary part 10 and force application part 11. Rotary part 10 is connected with the supporting axle A of upper and lower wind deflection blade 2, rotates with the rotation of supporting axle A. Force application part 11 is contacting from the center of rotation eccentric position of rotary part 10 with rotary part 10, and rotary part 10 is exerted a force. Force application part 11 gives the force component F in the direction of rotation of rotary part 10 of rotary part 10 and is configured to, and force component F when rotary part 10 is in the position corresponding with the closed position of upper and lower wind deflection blade 2 is bigger than the force component F that rotary part 10 is in during the position corresponding with the maximum open position of upper and lower wind deflection blade 2.
According to this structure, it is possible to suppress the distortion caused because of the deadweight G of upper and lower wind deflection blade 2 with good precision.
Above, describe the present invention for above-mentioned embodiment, but the present invention is not limited to above-mentioned embodiment. Such as, in embodiments, it is illustrated for being provided with the torsion-coil spring situation as an example of force application part 11, but is not limited to this situation, it is possible to use other force application part. For example, it is also possible to use leaf spring (leafspring), reversing spring (reversalspring), resin spring (resinspring), elastomeric spring (spring) etc. as force application part. Even if in this case, the relation of the mutual alignment relation and contact angle by suitably setting force application part and rotary part 10, it is also possible to reach the effect same with embodiment. Specifically, the force component in the direction of rotation of rotary part 10 giving rotary part 10 to major general's force application part is set as, force component when force component when upper and lower wind deflection blade 2 is in the closed position is in maximum open position than upper and lower wind deflection blade 2 is greatly. Thereby, it is possible to suppress the distortion caused because of the deadweight G of upper and lower wind deflection blade 2 with good precision. It is further possible to carry out setting as follows: be applied to the moment of torsion of supporting axle A by the active force of force application part, become big with the open angle of upper and lower wind deflection blade 2 and diminish. By this setting, it is possible to suppress the distortion caused because of the deadweight G of upper and lower wind deflection blade 2 with better precision.
In addition, in embodiments, although for upper and lower wind deflection blade 2 in the closed position time, the moment of torsion being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 is substantially maximum situation, namely supporting axle A and center of gravity 2g is in the situation of roughly the same height and is illustrated, but is not limited to this situation. Specifically, it is also possible to be set as, when position beyond upper and lower wind deflection blade 2 is in the closed position, it is applied to the moment of torsion of supporting axle A because of the deadweight G of upper and lower wind deflection blade 2 for substantially maximum. Even if in this case, the relation of the mutual alignment relation and contact angle by suitably setting torsion-coil spring 11 and rotary part 10, it is also possible to effectively reduce the moment of torsion being applied to supporting axle A because of the deadweight G of upper and lower wind deflection blade 2.
Additionally, in embodiments, although the movable range for upper and lower wind deflection blade 2 is that the situation from the 0 of closed position degree to 90 degree of maximum open position is illustrated, but is not limited to this, and these angles can be suitable for setting, and movable range is not limited to this.
Additionally, in embodiments, although the 1st extension 16a for the torsion-coil spring 11 contacted with rotary part 10 does not bend, and the situation for complete linearity is illustrated, but is not limited to this situation. Such as, as shown in figure 11, torsion-coil spring 21 can also have the extension 26a (the 1st extension 26a) of bent halfway. In the example shown in Figure 11, the extension 26a of torsion-coil spring 21 extends in the way of contacting with the front end of rotary part 10 (roller 13) from the opposition side (roller 13 side) of the center of rotation (connecting portion 12) of rotary part 10. In other words, the extension 26a of torsion-coil spring 21, from the end (being provided with the end of the side of roller 13) of the side contrary with the side of the connecting portion 12 being provided with rotary part 10, extends in the way of contacting with roller 13. Additionally, the front end of extension 26a is bending near the direction of rotary part 10. According to this shape, extension 26a is when the position exceeding bending point 26b contacts with roller 13, by increasing capacitance it is possible to increase torsion-coil spring 21 gives the force component in the direction of rotation of rotary part 10 of rotary part 10. Thus, particularly when the open angle of upper and lower wind deflection blade 2 is big, it is possible to more effectively suppress upper and lower wind deflection blade 2 to conduct oneself with dignity G and the distortion (lines 4,5 with reference to Figure 10) that causes. Therefore, it is possible to suppress the distortion caused because of the deadweight G of upper and lower wind deflection blade 2 with better precision.
In addition, in embodiments, although situation about contacting with roller 13 at side (inner side of the torsion-coil spring 11) place contrary for extension 16b with the 2nd of the 1st extension 16a for torsion-coil spring 11 is illustrated, but is not limited to this situation. Such as, as shown in figure 11, it is also possible to torsion-coil spring 21 is configured to, contact with roller 13 at opposition side (outside of the torsion-coil spring 21) place of the side contrary for extension 26c with the 2nd of the 1st extension 26a. According to this configuration, upper and lower wind deflection blade 2 rotates to open position from closed position, accompanying rotation parts 10 rotate (in fig. 11 for turning clockwise) in the same direction, release the 1st extension 26a near the direction of the 2nd extension 26c. That is, by rotary part 10, helical spring 21 is released to coiling direction. Thus, compared with the situation that helical spring 21 is released to the direction of extension by the rotary part 10 utilizing structure as shown in Figure 6, it is possible to maintain or improve the reliability of helical spring 21.
Additionally, in embodiments, although situation about contacting with torsion-coil spring 11 for eccentric jut 10a and roller 13 that roller 13 is arranged on rotary part 10 is illustrated, but is not limited to this situation. Roller 13 can also be not provided with, make eccentric jut 10a directly contact with torsion-coil spring 11.
Wherein, by the arbitrary embodiment in the middle of appropriately combined above-mentioned various embodiments, it is possible to play respective had effect.
