  2. Description of the Related Art In recent years, a register used for air conditioning for automobiles has an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and a small number of front movable fins of about 1 to 3 are provided inside the air outlet. In some cases, a thin register is manufactured mainly from a design or design demand. Such a thin register is known, for example, from Patent Document 1 below.

JP 2002-103954 A

  A thin register having an elongated air outlet has a front movable fin of about 1 to 3 sheets disposed along the longitudinal direction inside the elongated air outlet that is long in the longitudinal direction and short in the lateral direction. The rear movable fin is disposed in the short direction perpendicular to the front movable fin on the upstream side of the movable fin. However, the thin resistor has a long and narrow air outlet, and the air flow blown from the ventilation path toward the air outlet is compressed in the short direction. In particular, the phenomenon that the directivity of the wind when the rear movable fin is shaken in the longitudinal direction is likely to be deteriorated due to the contracted flow.

  In other words, a conventional thin register is generally a long and short rectangular air blow at the front part of a ventilation path 71 formed in the case body 70 of the register, as shown in FIG. An outlet 72 is provided, and for example, three front movable fins 73 with a small number of sheets are arranged along the longitudinal direction inside the air outlet 72, and a rear movable fin with a large number of sheets is disposed upstream of the front movable fin 73. 74 has a structure arranged in a direction orthogonal to the front movable fin 73.

  However, as shown in FIG. 11, such a thin register has an elongated shape in which the air outlet 72 is long in the longitudinal direction and short in the short direction, and therefore air blown from the ventilation path 71 toward the air outlet 72. The flow is compressed in the short direction and the contraction flow is likely to occur. In particular, when the rear movable fin 74 is swung left and right, that is, in the longitudinal direction, the air flow is generated in the vicinity between the rear movable fin 74 and the front movable fin 73. A contracted flow, that is, a flow of air compressed in the vertical direction is likely to occur.

  For this reason, when the front movable fin 73 is swung up and down and the rear movable fin 74 is swung left and right, that is, in the longitudinal direction, the direction of the air flow is returned by the contracted flow, so that the wind is difficult to bend and the rear movable fin 74 There existed a subject that the directivity of the wind when changing the direction of the fin 74 was easy to deteriorate.

  The present invention has been made in view of the above points, and is a thin register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and a movable louver is provided inside the air outlet. An object of the present invention is to provide a register capable of improving the directivity of wind.

  As a result of earnest development research on the register having the above structure, the present inventor has a wind current flow generated by rotating a movable louver on the downstream side, which is composed of contraction and deflection of the air flow. If the flow of the louver is large, when the upstream movable louver is rotated to transform the wind, the phenomenon of returning the current flow occurs, and the directivity of the wind direction by the upstream movable louver is likely to decrease. As a result, the inventors have reached the following invention.

That is, the register according to the present invention has an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and a movable louver before the air direction is changed in the lateral direction in the ventilation path inside the air outlet. In a register in which a movable louver is disposed on the upstream side of the front movable louver and the rear movable louver is disposed in the longitudinal direction.
A rear movable louver is arranged on the upstream side of the rear movable louver to change the wind direction in the short direction,
The inner movable louver is pivotally supported so that the first inner fin and the second inner fin are rotatable through a supporting shaft parallel to the longitudinal direction along both inner side surfaces in the ventilation path.
When changing the wind direction in the short direction, either the first back fin or the second back fin is rotated in the short direction, while the other second back fin or the first back fin is moved to the ventilation. The front movable louver is rotated in the direction opposite to the short direction in which the inner movable louver is swung while being held parallel to the road, and the wind direction is changed to the short direction.

  According to the present invention, for example, when the front movable louver is directed obliquely downward in the short direction, the rear movable louver is directed obliquely upward in the opposite direction, so that the air flow flowing through the ventilation path is first shortened by the rear movable louver. It is bent obliquely upward in the hand direction and is compressed, and passes through the rear movable louver in a compressed state, and changes the wind direction in the longitudinal direction according to the direction of the rear movable louver, and in that state, the air flow is next It passes through the front movable louver, is deflected and bent obliquely downward in the short direction, and is blown from the air outlet.

  For this reason, in the current transformation part that changes the wind direction in the short direction (for example, up and down), the part of the back movable louver becomes the contraction part and the part of the front movable louver becomes the deflection part, and the wind direction is obliquely below in the short direction. The current changing operation at the time of bending is divided into the contracted flow by the back movable louver and the deflection by the front movable louver.

  For this reason, when the air flow passes from the rear movable louver to the front movable louver, the contracted flow (compressed air flow) is reduced, thereby rotating the rear movable louver and changing the wind direction in the longitudinal direction. In this case, the phenomenon that the wind direction is returned by the contracted flow is reduced. For this reason, even in the case of a thin register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, the direction of the rear movable louver is elongated in the state where the direction of the front movable louver is shaken in the lateral direction. When swung in the direction, the wind is not returned by the contracted flow, and the direction of the wind can be changed favorably according to the direction of the rear movable louver to improve the directivity of the wind.

  Here, in the register, inner concave portions are formed on both inner side surfaces in the ventilation path, and the first inner fin and the second inner fin can be disposed so as to be housed in the inner concave portion. . According to this, when the first back fin or the second back fin does not perform the contraction operation of the air flow, the first back fin or the second back fin is stored in the inner concave portion, thereby reducing the pressure loss during blowing. Can be reduced.

Another register has an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and a pre-movable louver is disposed in the ventilation path inside the air outlet before changing the air direction in the lateral direction. In a register in which a rear movable louver is arranged on the upstream side of the front movable louver to change the wind direction in the longitudinal direction,
A rear movable louver is arranged on the upstream side of the rear movable louver to change the wind direction in the short direction,
The inner movable louver is pivotally supported in the ventilation path so that one inner fin is rotatable through a supporting shaft parallel to the longitudinal direction,
When the wind direction is changed to the short direction, the one back fin is rotated in the short direction, and the front movable louver is rotated in a direction opposite to the short direction in which the deep movable louver is swung, It is characterized by changing the wind direction to the short direction.

  According to the register of the present invention, in the same manner as described above, in the current changing portion that changes the wind direction in the short direction (for example, up and down), the back movable louver portion becomes the contracted portion, and the front movable louver portion becomes the deflecting portion. The current changing operation when the wind direction is bent obliquely downward in the short direction is divided into the contracted flow by the back movable louver and the deflection by the front movable louver.

  For this reason, as described above, when the air flow passes from the rear movable louver to the front movable louver, the contracted flow (compressed air flow) is reduced, thereby rotating the rear movable louver to change the wind direction. When changing in the longitudinal direction, the phenomenon that the wind direction is returned by the contracted flow is reduced. For this reason, even in the case of a thin register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, the direction of the rear movable louver is elongated in the state where the direction of the front movable louver is shaken in the lateral direction. When swung in the direction, the wind is not returned by the contracted flow, and the direction of the wind can be changed favorably according to the direction of the rear movable louver to improve the directivity of the wind.

  Here, the front movable louver is supported so that two or three front fins are pivotally supported via a support shaft parallel to the longitudinal direction, and all front fins are directed in the same direction. It can be configured to rotate and change the wind direction to the short direction.

Further, another register of the present invention has an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and is provided on both inner side surfaces in the ventilation path along the longitudinal direction in the vicinity of the air outlet on the upstream side. An angled ridge is formed along the longitudinal direction, and the direction of the angled surface of the angled ridge is directed upstream of the ventilation path, and the air flow in the ventilation path is closer to the center of the air outlet. In a register formed so as to be bent and blown, and a rear movable louver disposed on the upstream side of the chevron ridge to change the wind direction in the longitudinal direction,
A back movable louver having one back fin that changes the wind direction in the short direction is pivotally supported in the ventilation path on the upstream side of the rear movable louver via a support shaft along the longitudinal direction. The air flow which is contracted by the rotation of the back fin is bent in the opposite direction to the short direction bending by the back fin by the chevron ridge to change the wind direction to the short direction. .

  According to this invention, the wind direction can be changed to the short direction by turning only one back fin. For example, when the back fin is directed obliquely upward in the short direction, the airflow flowing through the ventilation path First, it is bent obliquely upward in the short direction by the back fin, and then flows through the movable louver in a contracted state, where the wind direction is changed in the longitudinal direction according to the direction of the movable louver, and in this state, The air flow is then deflected and bent obliquely downward in the short direction through the chevron ridges and blown from the air outlet.

  For this reason, the current transformation part which changes a wind direction to a short direction (for example, up and down), the location of a back fin turns into a contraction part, and the part of a mountain-shaped protruding item | line becomes a deflection part, and a wind direction is made into a short direction (for example, diagonally downward) ) Will be divided into the contracted flow by the back fin and the deflection by the chevron.

  For this reason, when the air flow passes through the ridges from the movable louver, the contracted flow (compressed air flow) is reduced, thereby turning the rear movable louver to change the wind direction to the longitudinal direction. The phenomenon that the wind direction is returned by the contracted flow is reduced. For this reason, even in the case of a thin register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, the direction of the rear movable louver is shaken in the longitudinal direction while the back fin is shaken in the lateral direction. Then, the wind is not returned by the contracted flow, and the direction of the wind can be favorably changed according to the direction of the rear movable louver to improve the directionality of the wind.

  Here, the above-mentioned chevron ridges are continuously formed on the opposite sides of the inner surface in the vicinity of the air outlet with the same cross section in the longitudinal direction of the air outlet, and further, on the downstream side of the chevron The surface can be formed in an open shape so as to spread forward. According to this, it is possible to improve the directivity of the wind when the direction of the fins of the rear movable louver is changed while the back fin is shaken in the short direction.

  According to the register of the present invention, when the direction of the front movable louver or the back movable louver is shaken in the short direction and the direction of the rear movable louver is shaken in the longitudinal direction, the wind is not returned by the contracted flow. The wind direction can be changed favorably according to the direction of the rear movable louver, and the directivity of the wind can be improved.

It is a longitudinal cross-sectional view when the wind direction is directed downward in the short direction. It is a longitudinal cross-sectional view when the wind direction is directed in the short direction. It is a longitudinal cross-sectional view of 2nd Embodiment which comprised the front movable louver from two front fins. It is a longitudinal section of a 3rd embodiment which constituted a back movable louver from one back fin. It is a longitudinal cross-sectional view of the same embodiment of the state which turned the wind direction on the transversal direction. It is a longitudinal cross-sectional view of 4th Embodiment which replaced with the front movable louver and used the mountain-shaped protruding item | line. It is a longitudinal cross-sectional view of the same embodiment of the state which turned the wind direction on the transversal direction. It is sectional explanatory drawing of the conventional register | resistor.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 show the register of the first embodiment. The case body 1 of the register is formed in a thin box shape, and an air passage 3 having a thin rectangular cross section is formed therein. An air inlet is formed at the end opening of the air passage 3, and an air outlet 2 having an elongated shape is formed on the front surface to blow out air passing through the air passage 3. Yes.

  That is, as shown in FIGS. 1 and 2, the air outlet 2 is formed in a flat and elongated slit shape, and is formed in a horizontally long rectangle that is long in the longitudinal direction (left and right direction) and short in the lateral direction (vertical direction). Yes. A front movable louver 4 composed of three lateral fins 41, 42, 43 is rotatably disposed just inside the air outlet 2 of the case body 1.

  The front movable louver 4 has three horizontal fins 41, 42, 43 arranged at predetermined intervals in the vertical direction along the longitudinal direction of the air outlet 2, and from both sides of each horizontal fin 41, 42, 43. The protruding horizontal support shafts 41a, 42a, 43a are rotatably supported on both side walls of the case body 1. The horizontal fins 41, 42, 43 of the front movable louver 4 are rotated synchronously and interlocked from the state shown in FIG. 2 to the state where the wind direction shown in FIGS. In cooperation with the back movable louver 6, the wind direction is changed in the vertical direction.

  Further, as shown in FIG. 2, inner concave portions 44 and 45 are respectively formed in the upper wall portion and the lower wall portion in the front portion of the case body 1, and the upper lateral fin 41 is formed in the upper inner concave portion 44. The lower lateral fins 43 are disposed so as to be retractable, and the lower lateral fins 43 are disposed so as to be retractable. When the wind direction is swung downward, the upper lateral fins 41 are moved from the inner recesses 44 as shown in FIG. In the case where the air is directed inward and obliquely downward and the wind direction is swung upward, the lower horizontal fin 43 is configured to protrude inward from the inner concave portion 45 and obliquely upward as shown in FIG.

  When air is blown straight in front of the air outlet 2, the upper and lower horizontal fins 41 and 43 are housed in the inner recesses 44 and 45 as shown in FIG. 2, minimizing pressure loss during front air blowing. The horizontal fin 42 at the intermediate position of the front movable louver 4 is disposed in the central longitudinal direction of the air outlet 2 and rotates in the same direction in synchronization with and interlocking with the upper and lower horizontal fins 41 and 43.

  The rotating mechanism 46 of the front movable louver 4 is configured by a manually operated link mechanism, a gear mechanism, or a motor drive mechanism. When air is blown straight ahead of the air outlet 2, the central lateral fin 42 is horizontal, When the upper and lower horizontal fins 41 and 43 are housed in the inner recesses 44 and 45 and the wind direction is directed downward, the central horizontal fin 42 is swung downward as shown in FIG. When the air is directed inward from the recess 44 and directed obliquely downward, and the wind direction is directed upward, the central lateral fin 42 is swung upward as shown in FIG. 5, and the lower lateral fin 43 is ejected inward from the inner recess 45 and obliquely upward. Configured to point to.

  A rear movable louver 5 is disposed in the ventilation path 3 upstream of the front movable louver 4, that is, immediately upstream of the front movable louver 4 in order to change the wind direction in the longitudinal direction of the air outlet 2, that is, in the left-right direction. The As shown in FIGS. 2 and 3, the rear movable louver 5 includes a large number of vertical fins 51 arranged in parallel in the longitudinal direction at intervals, and the large number of vertical fins 51 have support shafts 51a that protrude vertically. The air passage 3 is fitted into shaft holes provided in the upper and lower side walls of the ventilation path 3 and is pivotally supported.

  A large number of vertical fins 51 have a crank 51b attached to a lower support shaft 51a so that they rotate in synchronization with each other, and a link bar 51d is connected to a connecting shaft 51c displaced from the crank 51b. . In the rear movable louver 5, one of the support shafts 51 a is rotationally driven within a predetermined angle range by the rotation mechanism 56, and thereby, the many vertical fins 51 are rotated in the same direction in synchronization and interlocking with each other. This structure changes the wind direction in the longitudinal direction, that is, in the left-right direction. The rotation mechanism 56 of the rear movable louver 5 can be structured to rotate the support shaft 51a of the vertical fin 51 by operating the operation knob or rotating a cam or crank driven by a motor. The direction of the many vertical fins 51 is swung to the left and right by a moving operation or the like, and the air direction in the longitudinal direction of the air outlet 2 is changed.

  Further, in the ventilation path 3 immediately upstream of the rear movable louver 5, the inner movable louver 6 composed of the first inner fin 61 and the second inner fin cooperates with the front movable louver 4 in the vertical direction. Is arranged to change.

  In general, in a register in which a front movable louver and a rear movable louver are arranged in an orthogonal direction, the flow of wind generated when the downstream front movable louver is rotated is caused by the contraction and deflection of the air flow. If the front movable louver is configured with a large contraction flow, even if the rear movable louver is turned to change the wind direction, the phenomenon that the current flow is returned by the contraction occurs, and the directionality of the wind direction by the rear movable louver occurs. Is prone to decline.

  Therefore, in the present register, the rear movable louver 6 disposed on the upstream side of the rear movable louver 5 creates a contracted portion that compresses the airflow in the vertical direction, and the rear movable louver 6 moves the airflow upward or downward. After contracting downward, the front movable louver 4 deflects downward or upward to divide the up-and-down current transformation into contracted current by the rear movable louver 6 and deflection by the front movable louver 4. As a result, the phenomenon that the current transformation is returned between the rear movable louver 5 and the front movable louver 4 is suppressed, and the directivity when the rear movable louver 5 is rotated and the wind direction in the left-right direction is adjusted is improved. I have to.

  The back movable louver 6 has a first back fin 61 and a second back fin 62 arranged along the longitudinal direction of the air outlet 2 at the upper and lower portions in the ventilation path 3. Horizontal support shafts 61 a and 62 a projecting from both sides of the back fin 62 are rotatably supported on both side walls of the case body 1. Moreover, the 1st back fin 61 and the 2nd back fin 62 of the back movable louver 6 are each accommodated in the inner side recessed parts 63 and 64 provided in the upper wall part and lower wall part in the ventilation path 3 in a horizontal state. It is arranged as follows. Accordingly, when the first back fin 61 or the second back fin 62 does not perform the air flow contracting operation, the first back fin 61 is stored in the inner recess 63 and the second back fin 62 is stored in the inner recess 64. Thereby, the pressure loss at the time of ventilation is reduced.

  In such a back movable louver 6, when the front movable louver 4 is rotated obliquely downward and the wind direction is downward as shown in FIG. 4, for example, the second back fin 62 is inclined upward in conjunction with the operation. When the front movable louver 4 is rotated obliquely upward as shown in FIG. 5 and the wind direction is upward as shown in FIG. 5, the first back fin 61 is rotated obliquely downward in conjunction with the operation. It has become.

  For this purpose, the support shafts 61a and 62a of the first back fin 61 and the second back fin 62 of the back movable louver 6 are structured to be rotated by an operation knob or a motor-driven rotation mechanism 66. When the air is blown straight in the front direction, the rotation mechanism 66 keeps the first back fin 61 and the second back fin 62 in a horizontal state and accommodates them in the inner recesses 63 and 64 as shown in FIG. When the movable louver 4 is rotated and the wind direction is swung upward, as shown in FIG. 5, the first back fin 61 is directed downward and the front movable louver 4 is rotated and the wind direction is swung downward. 4, the second back fin 62 is configured to face upward. As described above, the back movable louver 6 rotates the first back fin 61 or the second back fin 62 in conjunction with the rotation of the front movable louver 4, and cooperates with the front movable louver 4 to move up and down. The direction of the wind is changed in the direction.

  That is, when the wind direction is directed downward, the rear movable louver 6 as shown in FIG. 4 is centered on the support shaft 62a at its end so that the tip of the second back fin 62 is directed obliquely upward. The second inner fin 62 is rotated in the clockwise direction so that the air flow in the ventilation path 3 is contracted upward. At this time, the front movable louver 4 has three horizontal fins 41, 42, 43 directed obliquely downward, but the current flow at this time is divided into a contracted flow by the back movable louver 6 and a deflection by the front movable louver 4. Thus, the phenomenon that the current flow caused by the rear movable louver 5 is returned between the rear movable louver 5 and the front movable louver 4 is suppressed.

  On the other hand, when the wind direction is directed upward, the rear movable louver 6 as shown in FIG. 5 is centered on the support shaft 61a at its end so that the front end of the first back fin 61 is directed obliquely downward. The first back fin 61 is rotated in the counterclockwise direction, and the air flow in the ventilation path 3 is contracted downward. At this time, the front movable louver 4 has the three horizontal fins 41, 42, 43 directed obliquely upward, so that the current flow at this time is reduced by the rear movable louver 6 and the front movable louver 4 as described above. Thus, the structure is configured to suppress the phenomenon in which the current is returned by the rear movable louver 5 between the rear movable louver 5 and the front movable louver 4.

  The register having the above-described configuration is attached to an instrument panel or a dashboard in an automobile so that the end of the case body 1 is connected to a ventilation duct (not shown). The air sent from the ventilation duct is blown out from the ventilation path 3 of the case body 1 through the air outlet 2.

  When the air blowing direction is directly in front of the register, as shown in FIG. 2, the horizontal fins 42 of the front movable louver 4 are parallel to the air blowing direction of the ventilation path 3, and the upper and lower horizontal fins 41, 43 are formed in the inner recesses 44, 45. The first inner fin 61 and the second inner fin 62 of the inner movable louver 6 are stored in the inner recesses 63 and 64. As a result, the air flow goes straight through the ventilation path 3, passes between the vertical fins 51 of the rear movable louver 5, and is blown straight forward from the air outlet 2 to the front front.

  At this time, if the vertical fins 51 of the rear movable louver 5 are rotated to the left and right, the wind direction changes in that direction, and there is no current flow in the vertical direction due to the front movable louver 4, so that the air flow contracts. However, it is possible to blow with a favorable change in the wind direction in the horizontal direction.

  On the other hand, when the air blowing direction is changed downward, as shown in FIG. 4, the horizontal fins 41, 42, 43 of the front movable louver 4 are rotated downward, and the inner movable louver 6 is moved to the tip of the second inner fin 62. Rotate the part to face upward.

  As a result, the airflow flowing through the ventilation path 3 is bent and contracted obliquely upward in the short direction by the second back fin 62 of the back movable louver 6 as shown in FIG. It passes between the vertical fins 51 of the movable louver 5 and changes the wind direction in the longitudinal direction (left-right direction) according to the direction of the rear movable louver 5, and in this state, the air flow is then the horizontal fin of the front movable louver 4. Passes between 41, 42, 43, is deflected and bent obliquely downward in the short direction, and is blown from the air outlet 2.

  On the other hand, when the air blowing direction is changed upward, as shown in FIG. 5, the lateral fins 41, 42, 43 of the front movable louver 4 are rotated upward, and the rear movable louver 6 is moved to the tip of the first rear fin 61. Rotate the part to face downward.

  As a result, the airflow flowing through the ventilation path 3 is bent and contracted obliquely downward in the lateral direction by the first back fin 61 of the back movable louver 6 as shown in FIG. It passes between the vertical fins 51 of the movable louver 5 and changes the wind direction in the longitudinal direction (left-right direction) according to the direction of the rear movable louver 5, and in this state, the air flow is then the horizontal fin of the front movable louver 4. Passes between 41, 42, 43, is deflected and bent obliquely upward in the short direction, and is blown from the air outlet 2.

  In this way, in the current changing portion that changes the wind direction in the short direction (vertical direction), the rear movable louver 6 portion becomes the contraction portion and the front movable louver 4 portion becomes the deflection portion, so that the wind direction changes in the short direction. The current changing operation at the time of bending downward or upward is divided into contraction by the rear movable louver 6 and deflection by the front movable louver 4.

  For this reason, when the air flow passes from the rear movable louver 5 to the front movable louver 4, the contracted flow (compressed air flow) is reduced, whereby the rear movable louver 5 is rotated to change the wind direction. When changing in the longitudinal direction, the phenomenon that the wind direction is returned by the contracted flow is reduced. Therefore, even in a register having an elongated air outlet 2 that is long in the longitudinal direction and short in the lateral direction, the direction of the rear movable louver 5 is changed with the direction of the front movable louver 4 being shaken in the lateral direction. When shaken in the longitudinal direction, the wind is not returned by the contracted flow, and the direction of the wind can be favorably changed according to the direction of the rear movable louver 5 to improve the directionality of the wind.

  FIG. 6 shows a register of the second embodiment. As shown in FIG. 6, the number of front movable louvers may be two, and the front movable louver 4 including only two upper and lower horizontal fins 41 and 43 is connected to the upper wall portion and the lower wall portion of the front portion in the case body 1. It can be pivotally supported via the support shafts 41a and 43a so as to be housed in the inner concave portions 44 and 45 provided on the inner surface. The register of FIG. 6 is particularly suitable for a thin register having a low case body 1 height.

  Similarly to the above, in the register shown in FIG. 6, when the wind direction is swung downward, the horizontal fin 41 on the front movable louver 4 is protruded obliquely downward with the tip portion protruding from the inner recess 44 toward the center. Then, the tip of the second back fin 62 of the back movable louver 6 is blown obliquely upward. On the other hand, when the wind direction is swung upward, as in the case of FIG. 5, the horizontal fins 43 below the front movable louver 4 are moved in the back direction with the tip portion protruding toward the center from the inner recess 45 and directed obliquely upward. The first louver 61 of the louver 6 is blown with the tip of the first back fin 61 obliquely downward. In this way, by forming the front movable louver 4 from only the two lateral fins 41 and 43, the shape of the slit-like air outlet 2 can be formed in a shorter and shorter direction.

  7 and 8 show the register of the third embodiment. In this example, a back movable louver 8 including a single back fin 81 is provided on the upstream side of the ventilation path 3 in the case body 1 in place of the above-described back movable louver 6. About the same part as the above, the same code | symbol as the above is attached | subjected to FIG.7, 8, and the description is abbreviate | omitted.

  As shown in FIGS. 7 and 8, the front movable louver 4 disposed just inside the air outlet 2 has two horizontal fins 41 and 43 vertically arranged along the longitudinal direction of the air outlet 2. The horizontal support shafts 41 a, 43 a that protrude from both sides of the horizontal fins 41, 43 are rotatably supported on both side walls of the case body 1. The horizontal fins 41, 43 of the front movable louver 4 are rotated in the vertical direction by a rotation mechanism 46, and the wind direction is changed in the vertical direction in cooperation with the rear movable louver 8.

  The rotation mechanism 46 of the front movable louver 4 is constituted by a manually operated link mechanism, a gear mechanism, or a motor drive mechanism. Similarly to the above, when air is blown straight ahead of the air outlet 2, the upper and lower horizontal fins 41 and 43 are accommodated in the inner recesses 44 and 45, and when the wind direction is directed downward, as shown in FIG. 7, the upper horizontal fin 41 is protruded inward from the inner recess 44 and directed obliquely downward, and the wind direction is changed. When facing upward, as shown in FIG. 8, the lower horizontal fins 43 are configured to protrude inward from the inner recess 45 and be directed obliquely upward.

  The rear movable louver 5 disposed on the upstream side of the front movable louver 4 has a large number of vertical fins 51 arranged side by side in the longitudinal direction, and the large number of vertical fins 51 are vertically supported. The shaft 51a is fitted into shaft holes provided in the upper side wall and the lower side wall of the ventilation path 3, and is pivotally supported. Similarly to the above, the rear movable louver 5 operates such that the vertical fins 51 are swung left and right by the rotation mechanism 56 and the wind direction is changed left and right.

  Further, in the ventilation path 3 immediately upstream of the rear movable louver 5, the rear movable louver 8 composed of only one rear fin 81 changes the wind direction in the vertical direction in cooperation with the front movable louver 4. It is arranged. The back fin 81 of the back movable louver 8 is formed in a long horizontally long shape along the longitudinal direction (horizontal horizontal direction) of the air outlet 2, and support shafts 81 a are projected from both side end portions thereof. The shaft 81a is pivotally supported so as to be vertically rotatable in the ventilation passage 3 in such a manner that the support shaft 81a is fitted into shaft holes provided in both side walls of the air.

  The rotation mechanism 86 of the back movable louver 8 is configured by a link mechanism or a motor drive mechanism that rotates the back fin 81 according to the operation of the operation knob, and when the blowing direction is changed downward, the downstream side of the back fin 81. When the tip portion is rotated so as to face obliquely upward, which is opposite to the air blowing direction, and the air blowing direction is changed upward, the downstream side tip portion of the back fin 81 is turned so as to face obliquely downward. Composed.

  When changing the blowing direction downward, the register having the above configuration rotates the horizontal fins 41 and 43 of the front movable louver 4 downward as shown in FIG. Is rotated diagonally upward.

  Accordingly, the air flow flowing through the ventilation path 3 is bent and contracted obliquely upward in the short direction by the back fins 81 of the back movable louver 8 as shown in FIG. 5 passes between the vertical fins 51 and changes the wind direction in the longitudinal direction (left and right direction) in accordance with the direction of the rear movable louver 5, and in that state, the air flow is next to the horizontal fins 41 of the front movable louver 4. 43 passes through 43, is deflected and bent obliquely downward in the short direction, and is blown from the air outlet 2.

  On the other hand, when changing the blowing direction upward, as shown in FIG. 8, the horizontal fins 41, 43 of the front movable louver 4 are rotated upward, and the rear movable louver 8 has the downstream end portion of the rear fin 81 downward. Rotate to face.

  Thus, the air flow flowing through the ventilation path 3 is bent and contracted obliquely downward in the short direction by the back fins 81 of the back movable louver 8 as shown in FIG. 5 passes between the vertical fins 51 and changes the wind direction in the longitudinal direction (left and right direction) in accordance with the direction of the rear movable louver 5, and in that state, the air flow is next to the horizontal fins 41 of the front movable louver 4. Passing through 43, deflected and bent obliquely upward in the short direction, and blown from the air outlet 2.

  As described above, in the current changing portion that changes the wind direction in the short direction (vertical direction), the rear movable louver 8 portion becomes the contracted portion and the front movable louver 4 portion becomes the deflecting portion, as described above. The current-transforming operation at the time of bending diagonally downward or upward in the short direction is divided into contraction by the rear movable louver 8 and deflection by the front movable louver 4. For this reason, when the air flow passes from the rear movable louver 5 to the front movable louver 4, the contracted flow (compressed air flow) is reduced, whereby the rear movable louver 5 is rotated to change the wind direction. When changing in the longitudinal direction, the phenomenon that the wind direction is returned by the contracted flow is reduced.

  9 and 10 show a register according to the fourth embodiment. In this example, instead of the front movable louver 4, chevron ridges 11 and 12 are provided at the upper and lower portions immediately inside the air outlet 2. It is provided along the longitudinal direction of the blower outlet 2.

  The air blower outlet 2 of this register is formed as an air blower outlet of a thin register having a horizontally long and short vertical width, and the upper and lower chevron ridges 11 and 12 are formed on the upper and lower inner side surfaces of the air blower 2 in the longitudinal direction. In the embodiment of this drawing, the height of each mountain-shaped ridge 11, 12 is about 9% of the height of the air outlet 2 (the length of the short side in the vertical direction), Depending on the height of the air outlet 2, it can be about 7 to 12% of the height.

  The upper and lower chevron ridges 11 and 12 are formed with inclined surfaces 11a and 12a on the upstream side. The inclined surfaces 11a and 12a on the upstream side of the angle ridges 11 and 12 are formed with their inclination directions directed toward the vertical fins 51 of the rear movable louver 5, and the inclined surfaces 11a and 12a of this embodiment The inclination angle with respect to the horizontal line is set to about 45 ° here, but can be set to about 35 ° to 55 ° depending on the height (length in the short direction) of the air outlet 2.

  As shown in FIGS. 9 and 10, the chevron ridges 11 and the chevron ridges 12 are symmetrical with respect to the horizontal center line of the air outlet 2 on the opposed upper and lower portions of the inner side surface of the air outlet 2. It is formed. Further, the chevron ridges 11 and the chevron ridges 12 are continuously formed in the longitudinal direction with the same cross section.

  On the other hand, the downstream surface of the ridges 11 and 12, that is, the surface on the front side of the register, is open so as to expand forward, that is, to expand toward the front diagonally upper side and the front diagonally lower side. Are formed as front inclined surfaces 11b and 12b. As shown in FIGS. 9 and 10, the angle ridges 11 and the angle ridges 12 are blown out from the air outlet 2 when the downstream end of the inner fin 81 of the inner movable louver 8 is directed upward or downward. The air flow direction is bent downward or upward.

  That is, when the downstream end of the back fin 81 of the back movable louver 8 is directed upward (obliquely upward), the airflow flowing through the ventilation path 3 flows along the vicinity of the upper wall surface as shown in FIG. It hits the inclined surface 11a of the mountain-shaped ridge 11 and is bent downward and blown obliquely downward. On the other hand, when the downstream end of the back fin 81 is directed downward (obliquely downward), the airflow flowing through the ventilation path 3 flows along the vicinity of the lower wall surface as shown in FIG. It strikes the inclined surface 12a of the strip 12, is bent upward, and is blown obliquely upward. In addition, when blowing obliquely downward or obliquely upward, the wind is well guided by the front inclined surfaces 11b and 12b opened so as to spread forward, and the directivity of the wind is not disturbed by the edge of the opening, It is designed to be blown.

  Similarly to the above, the turning mechanism 86 of the back movable louver 8 is constituted by a link mechanism that rotates the back fin 81 in accordance with the operation of the operation knob or a motor drive mechanism. When the tip of the downstream side of the fin 81 is rotated so as to face obliquely upward, which is opposite to the air blowing direction, and the air blowing direction is changed upward, the downstream tip of the back fin 81 is directed obliquely downward. Configured to rotate.

  When the blowing direction is changed downward, the register having the above configuration faces the downstream end portion of the back fin 81 of the back movable louver 8 obliquely upward, which is opposite to the blowing direction, as shown in FIG. Rotate as follows.

  As a result, the air flow flowing through the ventilation path 3 is bent and contracted obliquely upward in the short direction by the back fins 81 of the back movable louver 8, as shown in FIG. 5 passes between the vertical fins 51 and changes the wind direction in the longitudinal direction (left and right direction) according to the direction of the rear movable louver 5, and in this state, the air flow flowing through the ventilation path 3 is near the upper wall surface. It flows along and is bent downward by hitting the inclined surface 11a of the upper chevron 11 and blown obliquely downward from the air outlet 2.

  On the other hand, when changing the blowing direction upward, as shown in FIG. 10, the inner fin 81 of the inner movable louver 8 is rotated so that the downstream end portion thereof faces downward.

  As a result, the airflow flowing through the ventilation path 3 is bent and contracted obliquely downward in the short direction by the back fins 81 of the back movable louver 8 as shown in FIG. 5 passes between the vertical fins 51 and changes the wind direction in the longitudinal direction (left and right direction) according to the direction of the rear movable louver 5, and in this state, the air flow flowing through the ventilation path 3 is near the lower wall surface. It flows along and is bent upward by hitting the inclined surface 12a of the lower chevron 12 and blown obliquely upward from the air outlet 2.

  As described above, in the current changing portion that changes the wind direction in the short direction (vertical direction), the back movable louver 8 portion becomes the contracted portion and the chevron ridges 11 and 12 become the deflecting portions. The current changing operation when the wind direction is bent obliquely downward or upward in the short direction is divided into the contracted flow by the rear movable louver 8 and the deflection by the mountain-shaped ridges 11 and 12. For this reason, when the air flow passes through the chevron ridges 11 and 12 from the rear movable louver 5, the contracted flow (compressed air flow) is reduced, whereby the rear movable louver 5 is rotated to move the wind direction. The phenomenon that the wind direction is returned by the contracted flow is reduced when the is changed to the left and right longitudinal direction.

  For this reason, even in a register having an elongated air outlet 2 that is long in the longitudinal direction and short in the lateral direction, the direction of the rear movable louver 5 is changed while the direction of the rear movable louver 8 is shaken in the lateral direction. When shaken in the longitudinal direction, the wind is not returned by the contracted flow, and the direction of the wind can be favorably changed according to the direction of the rear movable louver 5 to improve the directionality of the wind.

  In the above embodiment, the register having the horizontally long air outlet 2 is configured by providing the front movable louver 4 with the horizontal fins 41, 42, 43 and the rear movable louver 5 with the vertical fins 51. In addition, in a state where they are rotated by 90 degrees, it can be applied to a vertically long thin register. In the case of a vertically long thin register, an air outlet having a vertically elongated shape is provided, and a vertical fin is provided in a front movable louver. Lateral fins can be arranged side by side on the rear movable louver, or chevron ridges can be provided on both the left and right sides inside the vertically long air outlet instead of the front movable louver. In this case, the back fins of the back movable louver are in the same vertical direction as the vertical fins or the ridges of the front movable louver.
