Description

  The present invention relates to an air outlet adjustment register used for an air outlet of an air conditioner such as an automobile, and in particular, has an elongated air outlet that is long in the horizontal and horizontal directions and short in the vertical and vertical directions, and is located inside the air outlet. The present invention relates to a register provided with a front movable louver having lateral fins along the longitudinal direction.

  As a register for adjusting the air blowing, a laterally movable louver and a longitudinally movable louver are arranged in front and back in a bezel or retainer that forms a ventilation path, and when the air is blown from an air outlet provided in the bezel, In general, a register that adjusts the air blowing direction by changing the angle of each fin of the longitudinally movable louver is used for air conditioning of automobiles.

In addition, as this type of register, a register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and provided with a few movable fins on the inside of the air outlet is mainly designed. There are cases where it is produced from the demands of sex and design. Such a register is known, for example, from Patent Document 1 below.
JP 2002-103954 A

  In this conventional register, the air outlet has a horizontally long shape that is long in the horizontal direction and short in the vertical direction, and the front movable louver has three horizontal louvers that rotate horizontally in the horizontal direction inside the air outlet. A longitudinal louver of a rear movable louver is pivotally supported via a vertical shaft at a rear portion at the back thereof.

  This type of register has an air outlet that is horizontally long in consideration of design, etc., and the front movable louver has a small number of horizontal fins, and the orientation of the front movable louver is adjusted up and down. In this case, the three horizontal fins rotate in the same direction and operate to change the wind direction.

  However, in the above register, a front movable louver having three horizontal fins is arranged in a thin air outlet that is horizontally long and short in the vertical direction. Therefore, when only a single horizontal fin is provided in the front movable louver. Compared with, pressure loss during blowing tends to increase due to the air resistance of the three horizontal fins.

  Further, as shown in FIG. 8 showing the air flow during blowing, when the front movable louver 30 is adjusted upward, for example, and the three horizontal fins 31, 32, 33 are shaken upward, Turbulence occurs due to the influence of airflow passing through the gap between the upper wall surface and the gap between the lowermost lateral fin 33 and the lower wall surface, and the direction of the wind tends to spread up and down. For this reason, the directivity of the wind at the time of adjusting the front movable louver 30 up and down easily deteriorates the performance of blowing the wind having a sufficient flow velocity in the direction of the horizontal fins 31 to 33.

  On the other hand, a register has been prototyped in which a front movable louver with a single horizontal fin is arranged inside the thin air outlet so that it can be adjusted in the vertical direction. Or, when the wind direction is changed to the upper or lower side by shaking downward, many airflows pass straight through the gap between the horizontal fin and the upper or lower wall surface, and this airflow causes There was a problem that the flow rate was easily affected.

  The present invention has been made in view of the above points, and in a register having a thin air outlet and a small number of lateral fins, the lateral fins can be rotated without increasing pressure loss during blowing. An object of the present invention is to provide a register capable of ensuring good wind directivity according to the above.

  In order to achieve the above object, the register according to claim 1 of the present invention has an elongated air outlet that is long in the horizontal and horizontal directions and short in the vertical and vertical directions, and the horizontal and lateral directions at the inner front portion of the air outlet. In the register in which the front movable louver is disposed along the front side, the front movable louver pivotally supports one central lateral fin so as to be pivotable in the horizontal lateral direction at a substantially vertical center inside the air outlet. The upper auxiliary lateral fin is pivotally supported near the upper wall surface inside the air outlet and is pivotable in the horizontal lateral direction, and the lower auxiliary lateral fin is arranged close to the lower wall surface inside the air outlet. An auxiliary horizontal fin rotation mechanism is connected to the rotation shafts of the central horizontal fin, the upper auxiliary horizontal fin, and the lower auxiliary horizontal fin. When the central lateral fin is swung up or down, the turning mechanism Auxiliary horizontal fin is characterized in that rotating the upper auxiliary horizontal fin and lower auxiliary horizontal fin as pushed out toward the downstream side edge portion on the inner side of the channel.

  Here, the upstream side and the downstream side mean the upstream side or the downstream side of the airflow flowing through the flow path, and in each member, the front part means the downstream part and the rear part means the upstream part.

  According to this invention, when the central horizontal fin is swung upward or downward, the upper auxiliary horizontal fin is pushed toward the inner side of the flow path by the operation of the auxiliary horizontal fin rotation mechanism. In other words, the lower auxiliary lateral fin is rotated obliquely downward and downstream, and the lower auxiliary lateral fin is rotated obliquely upward and downstream so that its downstream edge protrudes toward the inside of the flow path. As a result, the airflow that flows near the upper wall surface and the lower wall surface of the flow path is restricted so as to gather around the central horizontal fin by the upper auxiliary horizontal fin and the lower auxiliary horizontal fin, and follows the upper surface or the lower surface of the central horizontal fin. It flows like.

  For this reason, the airflow which blows off from an air blower becomes a flow along the direction which a center horizontal fin faces, and can improve the directivity of the wind at the time of the vertical adjustment of a center horizontal fin. In addition, the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are located close to the upper wall surface or close to the lower wall surface when the front movable louver is horizontally adjusted. It can be minimized.

  According to a second aspect of the present invention, in the register of the first aspect, when the central lateral fin is in a horizontal state and the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are in a horizontal state, the upper auxiliary horizontal fin and the lower auxiliary horizontal fin The fins are housed in housing recesses provided on the upper wall surface and the lower wall surface of the flow path.

  According to this invention, when the central lateral fin is in a horizontal state and the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are in a horizontal state, the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are on the upper wall surface and the lower wall surface of the flow path. Because it is stored in the storage recess provided, when blowing the wind straight ahead of the air outlet, pressure loss during blowing can be minimized, and the upper auxiliary horizontal fin or lower auxiliary from the front of the register Since the horizontal fins are difficult to see, the design of the register can be improved.

  According to a third aspect of the present invention, in the register of the first or second aspect, the position of the downstream side edge of the central lateral fin is located downstream of the positions of the downstream side edge of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin. The rotation axis of the central lateral fin is positioned in the vicinity of the downstream edge thereof, and the rotation axes of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are located at the upstream edge of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin. It is located in the vicinity.

  According to the present invention, the air flow blown out from the air outlet becomes a flow along the direction of the central lateral fin, which further improves the directivity of the wind when adjusting the vertical position of the central lateral fin. it can.

  According to a fourth aspect of the present invention, in the register according to the first, second, or third aspect, the front and rear widths of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are shorter than the front and rear widths of the central horizontal fin. And the position of the pivot axis of the lower auxiliary horizontal fin is located upstream of the position of the pivot axis of the central lateral fin.

  According to this invention, the air flow blown out from the air outlet becomes a flow further along the direction of the central horizontal fin, and the directivity of the wind at the time of adjusting the vertical of the central horizontal fin is further improved. Can do. Further, the upper auxiliary horizontal fin and the lower auxiliary horizontal fin having a short front-rear width can reduce pressure loss and a decrease in wind speed when the fin is swung up or down.

  According to a fifth aspect of the present invention, in the register of the first aspect, the auxiliary horizontal fin rotation mechanism includes a crank having an eccentric crankshaft attached to the rotation shaft of the central horizontal fin, and a cam groove on the crankshaft. A first cam member engaged and pivotally attached to the pivot shaft of the upper auxiliary lateral fin; and a second cam member engaged with the crankshaft and pivotally attached to the pivot shaft of the lower auxiliary lateral fin. Characterized in that the downstream side edges of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are rotated toward the inside of the flow path according to the vertical rotation of the central horizontal fin. To do.

  According to the present invention, using the auxiliary horizontal fin rotation mechanism having a relatively simple structure, the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are rotated by following the vertical rotation of the central horizontal fin, and the central horizontal fin is rotated. When the fins are swung up or down, the downstream side edges of the upper auxiliary horizontal fins and the lower auxiliary horizontal fins are rotated toward the inner side of the flow path, and the upper auxiliary horizontal fins and the lower auxiliary horizontal fins You can change the direction.

  According to the register of the present invention, even in a register provided with a small number of horizontal fins in a thin air outlet, it is good according to the rotation of the central horizontal fin while suppressing pressure loss during blowing. Therefore, the upper auxiliary horizontal fin or the lower auxiliary horizontal fin is difficult to see from the front of the register, and the design of the register can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 shows a front view of the register, FIG. 2 shows a left side view thereof, and FIG. 3 shows a horizontal cross-sectional view thereof. 4 is a longitudinal sectional view thereof, FIG. 5 is an exploded perspective view of the auxiliary horizontal fin rotation mechanism 10, and FIG. 6 is a left side view when the auxiliary horizontal fin rotation mechanism 10 is operated. FIG. 7 shows a cross-sectional view thereof.

  In these figures, reference numeral 1 denotes a bezel in which a rectangular horizontally long air outlet 18 is formed in the front. As shown in FIG. 1, the air outlet 18 is formed in a flat and elongated rectangle, and is formed in a horizontally long rectangle that is long in the longitudinal direction and short in the lateral direction.

  A fitting portion (not shown) for connecting to the retainer 2 is provided on the back side of the bezel 1, and the duct-like retainer 2 is fitted and connected to the fitting portion. Bearing portions 1a for the front movable louver 3 are formed on the left and right side walls inside the air outlet 18 of the bezel 1, and the rotating shaft 7a of the central lateral fin 7 of the front movable louver 3 and the upper auxiliary lateral fin 8 are formed on the bearing portion. The pivot shaft 8a and the pivot shaft 9a of the lower auxiliary lateral fin 9 are supported.

  The retainer 2 is formed in a substantially square duct shape, and a ventilation flow path 5 is formed therein. Bearing portions 2a are formed at predetermined intervals on the upper wall and lower wall of the downstream edge of the retainer 2, and the vertical fins 4a of the rear movable louver 4 are pivotally supported on these bearing portions 2a as shown in FIG. A bezel 1 having a substantially rectangular air outlet 18 formed in the front is fitted to the front of the retainer 2 with the air outlet 18 aligned with the opening of the flow path 5. It is formed so as to communicate from the retainer 2 to the air outlet 18 of the bezel 1.

  The front movable louver 3 is arranged at one central lateral fin 7 that can be pivoted up and down, and above and below the central lateral fin 7, and rotates up and down according to the pivoting operation of the central lateral fin 7. An upper auxiliary horizontal fin 8 and a lower auxiliary horizontal fin 9 that move; an auxiliary horizontal fin rotation mechanism 10 that rotates the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 in conjunction with the rotation of the central horizontal fin 7; It is configured with. The central lateral fin 7 has pivot shafts 7a projecting at both ends, and as shown in FIGS. 1 and 5, one pivot shaft 7a penetrates the side wall of the flow path 5 and projects outward. A crank 11 is attached to the tip of the shaft 7a.

  As shown in FIG. 4, when the central lateral fin 7 is in a horizontal state, that is, when the wind direction is adjusted so as to blow straight forward, the rotation shaft 7a of the central lateral fin 7 is downstream from the center of the fin body. It is located at the downstream edge. As a result, when the central lateral fin 7 is swung upward or downward (rotated), the upstream edge of the central lateral fin 7 is largely directed upward or downward.

  As shown in FIG. 4, the upper auxiliary lateral fin 8 is disposed close to the upper wall surface 6a in the flow path 5, while the upper wall surface 6a is formed with a storage recess 6c, and the upper recess in the storage recess 6c. The auxiliary horizontal fins 8 are stored in a horizontal state. The lower auxiliary horizontal fin 9 is disposed close to the lower wall surface 6b in the flow path 5, while the lower wall surface 6b is formed with a storage recess 6d, and the lower auxiliary horizontal fin 9 is formed in the storage recess 6d. It is designed to be stored horizontally. The upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 are formed so that the width in the front-rear direction is as short as about ½ of the width in the front-rear direction of the central horizontal fin 7.

  That is, the front / rear width of the central lateral fin 7 is formed to be wide and about twice as long as the front / rear width of the upper auxiliary lateral fin 8 and the lower auxiliary lateral fin 9, and further, the central lateral fin 7 is upstream in the plan view. The side halves are arranged so as to overlap the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9, and the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 are positioned above or below the central horizontal fin 7 and downstream from the horizontal state. The side edge is pivotally supported so as to protrude toward the flow path 5.

  As shown in FIGS. 4 and 5, the rotation shaft 8 a of the upper auxiliary horizontal fin 8 protrudes on both sides near the upstream edge of the upper auxiliary horizontal fin 8, and the rotation shaft 9 a of the lower auxiliary horizontal fin 9 is The lower auxiliary horizontal fins 9 are protruded on both sides in the vicinity of the upstream edge portion, and the positions thereof are substantially the same planar positions as the upstream edge portion of the central horizontal fin 7. That is, the rotational axes 8 a and 9 a of the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 have a reverse positional relationship with the rotational axis 7 a of the central horizontal fin 7 in the front-rear direction.

  Accordingly, as shown in FIG. 7, when the central lateral fin 7 is swung upward (rotated) and the upper auxiliary lateral fin 8 is swung downward (rotated), the central lateral fin 7 and the upper auxiliary lateral fin are swung. The fins 8 are substantially parallel, and when the central horizontal fin 7 is swung downward and the lower auxiliary horizontal fin 9 is swung upward, the central horizontal fin 7 and the lower auxiliary horizontal fin 9 operate so as to be substantially parallel.

  In order to make the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 move as described above when the central horizontal fin 7 is swung upward or downward as described above, the auxiliary horizontal fin is placed outside the left side surface of the bezel 1. A fin rotation mechanism 10 is provided. The auxiliary horizontal fin rotation mechanism 10 includes a crank 11 that is attached to the rotation shaft 7a of the central horizontal fin 7 described above, and a first cam member 13 that is attached to the rotation shaft 8a of the upper auxiliary horizontal fin 8. The second cam member 14 is pivotally attached to the rotating shaft 9a of the lower auxiliary lateral fin 9.

  An elongated cam groove 13 a bent in a substantially U shape is formed in the first cam member 13, and a similar cam groove 14 a is formed in the second cam member 14. These cam grooves 13a and 14a are formed as through holes. Further, as shown in FIG. 2, the first cam member 13 and the second cam member 14 are formed symmetrically with respect to each other, while the upper auxiliary horizontal fins 8 and the lower auxiliary horizontal fins disposed at the upper part and the lower part. In the usage mode in which the upper or lower part is attached to the nine rotating shafts 8a, 9a, the rotating shafts 8a, 9a are arranged symmetrically with the horizontal line as the symmetrical line. Further, as shown in FIG. 5, a crankshaft 12 projects from the tip of the crank 11 that is pivotally attached to the rotating shaft 7a of the central lateral fin 7. The crankshaft 12 is connected to the first cam. The cam groove 13a of the member 13 and the cam groove 14a of the second cam member 14 are both inserted and assembled.

  The upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 linked to the auxiliary horizontal fin rotating mechanism 10 configured as described above have the vertical direction of the central horizontal fin 7 facing straight front as shown in FIG. In the horizontal direction, the crank 11, the first cam member 13, and the second cam member 14 act as horizontal postures and are stored in the storage recesses 6 c and 6 d. On the other hand, when the central lateral fin 7 is rotated downward as shown in FIG. 7A, that is, when the direction of the central lateral fin 7 is swung downward, the orientation of the upper auxiliary lateral fin 8 is similarly lower. And the direction of the lower auxiliary horizontal fin 9 is rotated upward. In other words, the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 are rotated so that the downstream edge thereof is pushed into the flow path 5 regardless of whether the direction of the central horizontal fin 7 is swung upward or downward. To do.

  A rear movable louver 4 is disposed in a flow path 5 behind (back) the front movable louver 3. In the rear movable louver 4, a plurality of vertical fins 4 a are arranged side by side vertically with a constant interval. Each vertical fin 4a is provided with a rotating shaft at the upper and lower portions, and the upper and lower rotating shafts are supported by bearings provided on the upper wall and the lower wall of the flow path 5, and are supported so as to be rotatable left and right. ing.

  As shown in FIG. 1, an operation knob 19 is externally fitted to the central lateral fin 7 so as to be slidable in the left-right longitudinal direction, and the central lateral fin 7 can be rotated up and down by holding the operation knob 19. In addition, the rear movable louver 4 is adjusted to the left and right by sliding the operation knob 19 in the left and right direction.

  For this reason, although not shown in the drawing, the rear portion of the operation knob 19 is provided with an engaging portion that engages with one vertical fin 4a of the rear movable louver 4 and includes all the vertical fins 4a. A crank (not shown) is pivotally attached to the rotating shaft 4b of the vertical fin 4a, and the crankshafts of the cranks are connected to each other by a single link bar. As a result, when the operation knob 19 is slid left and right on the central horizontal fin 7, the vertical fins 4a of the rear movable louver 4 are pivoted to the left and right to adjust the wind direction to the left and right.

  The register having the above-described configuration is attached to an instrument panel or a dashboard in an automobile with the end of the retainer 2 connected to a ventilation duct (not shown). Air sent from the ventilation duct during use of the air conditioner is blown out from the flow path 5 in the retainer 2 through the air outlet 18.

  As shown in FIGS. 2 and 4, when the central lateral fin 7 of the front movable louver 3 is in a horizontal state, that is, in a state of facing straight forward, both the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 maintain the horizontal state, It is stored in the storage recesses 6c and 6d of the wall surface 6a and the lower wall surface 6b. Therefore, the airflow flowing through the flow path 5 is blown with very little pressure loss in the horizontal front direction toward the central lateral fin 7 without receiving almost any air resistance by the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9. The Thereby, the pressure loss at the time of level adjustment can be reduced as compared with a register in which three conventional horizontal fins are arranged in parallel with the air outlet.

  On the other hand, as shown in FIGS. 2 and 4, when the central lateral fin 7 is in a horizontal state, the operation knob 19 is operated to rotate the central lateral fin 7 upward as shown in FIG. In the first cam member 13 and the second cam member 14 of the auxiliary lateral fin rotation mechanism 10, as shown in FIG. 2, the crankshaft 12 positioned at the central corner of the cam groove 13a and the cam groove 14a is shown in FIG. As shown in a), the cam groove 13a and the cam groove 14a are moved obliquely downward. At this time, along with the movement of the crankshaft 12, the first cam member 13 rotates about the rotation shaft 8a in the clockwise direction of FIG. 6A, and the second cam member 14 counteracts about the rotation shaft 9a. Rotate clockwise.

  As a result, as shown in FIG. 7A, the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 are moved by the action of the cam grooves 13a, 14a of the first and second cam members 13, 14 and the crankshaft 12. Each of the downstream side edges is rotated so as to protrude toward the inside of the flow path 5, that is, the upper auxiliary horizontal fin 8 is turned obliquely downward, and the lower auxiliary horizontal fin 9 is turned obliquely upward. .

  Thereby, the airflow flowing from the flow path 5 toward the air outlet 18 is gathered in the vicinity of the vertical center of the flow path 5 by the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9, that is, in the vicinity of the central horizontal fin 7. The air flow collected in the vicinity of the central lateral fin 7 flows along the central lateral fin 7 and is blown toward the obliquely upward direction toward the central lateral fin 7.

  At this time, as shown in FIG. 7A, the lower auxiliary horizontal fin 9 is positioned so that at least half of the upper surface of the lower auxiliary horizontal fin 9 overlaps the central horizontal fin 7 in plan view. Are directed in the same direction, so that the air flow is effectively collected in the vicinity of the central lateral fin 7 and the wind is caused to flow along the central lateral fin 7 so that a gap between the lower wall surface 6b of the flow path 5 and the lower auxiliary lateral fin 9 is formed. There is almost no air flow flowing straight in front.

  Further, the upper auxiliary lateral fin 8 rotates downward and operates so that its downstream edge is pushed toward the inside of the flow path 5, and the air flow flowing through the flow path 5 is near the periphery of the central lateral fin 7. Therefore, an air flow along the central horizontal fin 7 is generated, and an air flow that flows straight in front of the gap between the upper wall surface 6a of the flow path 5 and the upper auxiliary horizontal fin 8 hardly occurs.

  Therefore, unlike the conventional register having three horizontal fins, the air flow flowing along the central horizontal fin 7 flows smoothly without being disturbed, and the central horizontal fin 7 of the front movable louver 3 is moved upward. It is possible to greatly improve the directivity when shaken.

  On the other hand, as shown in FIGS. 2 and 4, when the central lateral fin 7 is in the horizontal state, the operation knob 19 is operated to rotate the central lateral fin 7 downward as shown in FIG. 7B. In the first cam member 13 and the second cam member 14 of the auxiliary lateral fin rotation mechanism 10, the crankshaft 12 positioned at the central corner of the cam groove 13a and the cam groove 14a as shown in FIG. In this manner, the cam groove 13a and the cam groove 14a are moved obliquely upward. At this time, along with the movement of the crankshaft 12, the first cam member 13 rotates about the rotation shaft 8a in the clockwise direction of FIG. 6A, and the second cam member 14 counteracts about the rotation shaft 9a. Rotate clockwise.

  As a result, as shown in FIG. 7B, the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 are moved by the action of the cam grooves 13a and 14a of the first and second cam members 8 and 9 and the crankshaft 12. In the same manner as described above, the respective downstream edges are rotated so as to protrude toward the inside of the flow path 5 so that the upper auxiliary horizontal fin 8 faces obliquely downward and the lower auxiliary horizontal fin 9 turns obliquely upward. Move.

  Thereby, the airflow flowing from the flow path 5 toward the air outlet 18 is gathered in the vicinity of the vertical center position of the flow path 5 by the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9, that is, in the vicinity of the central horizontal fin 7. The air flow collected in the vicinity of the central lateral fin 7 flows along the central lateral fin 7 and is blown toward an obliquely downward direction toward the central lateral fin 7.

  At this time, as shown in FIG. 7B, the upper auxiliary horizontal fin 8 is positioned so that more than half of its upper surface overlaps the central horizontal fin 7 in plan view, and rotates in the same direction as the central horizontal fin 7. Therefore, the air flow is collected in the vicinity of the central lateral fin 7, and the air flowing straight in front through the gap between the upper wall surface 6 a and the upper auxiliary horizontal fin 8 and the gap between the lower wall surface 6 b and the lower auxiliary horizontal fin 9. There is almost no flow.

  Further, the lower auxiliary horizontal fin 9 rotates upward and operates so that its downstream edge is pushed toward the inside of the flow path 5, and the air flow flowing through the flow path 5 is near the periphery of the central horizontal fin 7. Therefore, an air flow along the central horizontal fin 7 is generated, and an air flow that flows straight through the gap between the lower wall surface 6b of the flow path 5 and the lower auxiliary horizontal fin 9 is hardly generated.

  Therefore, similarly to the above, when the central lateral fin 7 is shaken downward, the air flow flowing along the central lateral fin 7 is disturbed like a conventional register having three lateral fins. Therefore, the directivity when the central lateral fin 7 of the front movable louver 3 is swung down can be greatly improved.

  In the above-described embodiment, the movement of tilting the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 so as to protrude toward the inside of the flow path 5 following the rotation of the central horizontal fin 7 is performed by the crank 11, 1. Realized by the auxiliary horizontal fin rotation mechanism 10 using the second cam members 13 and 14, but the movement of the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 is realized by using another link mechanism or cam mechanism. You can also

  In the above embodiment, the rectangular air outlet 18 is used. However, the air outlet may not be necessarily rectangular but may be an elliptical air outlet having an elongated shape.

  The storage recesses 6c and 6d for storing the upper auxiliary horizontal fins 8 and the lower auxiliary horizontal fins 9 are stepped recesses having steps, but are recesses that can store the upper auxiliary horizontal fins 8 and the lower auxiliary horizontal fins 9. If there is, the shape such as a recess having a concave curved surface is arbitrary.
