Japanese Patent Laid-Open No. 2004-210111 JP 2011-79374 A

  Registers used for air conditioning in automobiles may be installed with an air outlet opening on the front of the instrument panel, but the location of the register is related to the display, operation panel, etc. installed there. May be placed at the top of the instrument panel near the dashboard.For example, when a register is placed near the dashboard at the top of the instrument panel, it should be aligned with the slope on the top of the dashboard at the top of the instrument panel. The air outlet of the register is formed in an inclined shape with the upper part retracted upstream and the lower part protruded downstream (see, for example, Patent Document 1).

  In addition, when a register is installed with the air outlet of the register placed at the top of the instrument panel, a curved surface that bulges out so as to protrude toward the occupant side is provided on the front of the instrument panel below the air outlet. There is a case where a design provided with a shelf portion is used for an instrument panel.

  When the front movable louver is swung downward, the resistor attached to the upper part of the instrument panel with such a design is bent downward by the air blown from the air outlet. The phenomenon of flowing downward along the outer surface of the shelf tends to occur so as to stick to the surface of the shelf that bulges.

  That is, in the instrument panel on the lower side of the air outlet, when a shelf having a curved surface that bulges so as to protrude toward the occupant is located, when blowing air obliquely downward, the Coanda effect of the fluid, A phenomenon occurs in which air flows so as to stick to the outer surface of the shelf. For this reason, when the passenger operates the front movable louver downward, for example, in order to blow air from his / her chest toward the waist, the air blown obliquely downward is applied to the outer surface of the shelf of the instrument panel. It flows underneath and sticks along, making it difficult to direct the wind in the direction desired by the passenger.

  Therefore, the applicant of the present invention is a case where a shelf having a curved surface that bulges out toward the occupant side is located on the front surface of the instrument panel below the air outlet of the register in Patent Document 2. However, a resistor has been proposed that prevents the wind that flows downward so that it sticks along the outer surface of the shelf when blowing air obliquely downward.

  This register is provided with a bypass passage at the bottom of the flow path inside the air outlet, and the wind that flows upward through the bypass passage is applied to the mainstream air that is blown obliquely downward from the lower part of the air outlet, and blown obliquely downward However, as a bypass passage, a stepped portion is formed at the bottom of the flow path in the register, and a rectangular box-shaped flow path member is fitted into the step-shaped flow path member. It is necessary to provide a plurality of air inlets and outlets, and there are many components for that purpose, and the structure is complicated.

  The present invention solves the above-described problem, and even when a bulging curved shelf is located in front of the air outlet of the air outlet, the wind sticking phenomenon can be prevented with a simple configuration, An object of the present invention is to provide a register capable of improving the directivity of the.

In the register according to the present invention, a retainer having a flow path is connected to the back side of a bezel provided with an air outlet, and a front rotating louver is provided inside the air outlet by a bearing portion provided on a wall portion of the bezel. is arranged to provide a plurality of fins pivotably, to blow side near the front of the air outlet, at a site ledge of the bulging curved is positioned at the installation registers,
The fin on the shelf side of the front movable louver is provided with a notch opening at the downstream end of the fin and along the longitudinal direction of the fin, and the front movable louver is inclined toward the shelf side. When rotating, the airflow is obliquely blown through the notch opening to the wind flowing along the direction of the front movable louver, and the airflow flowing in the direction of the shelf is changed to a direction away from the shelf. It is characterized by.

  According to this invention, when the fin of the front movable louver is rotated so as to be inclined toward the shelf side, the air flow is obliquely blown through the notch opening portion with respect to the air flow flowing inclined along the fin, Since the airflow that flows in the direction of the shelf is changed to the direction away from the shelf, this can prevent the phenomenon of sticking of the wind that flows along the outer surface of the bulging curved shelf, and the user can The directivity of the wind can be improved by correctly blowing air in the direction of the operated front movable louver. In addition, it is possible to prevent the wind sticking phenomenon with a simpler configuration than the conventional one.

  Here, the front movable louver is disposed in the front part inside the air outlet with a plurality of horizontal fins pivotally supported in the horizontal horizontal direction, and the air outlet retreats the upper part to the upstream side and the lower part to the downstream side. It can be configured such that a resistor is attached to a portion formed so as to protrude so as to protrude and the shelf is located on the lower front side of the air outlet.

  According to this invention, for example, when the register is installed on the upper side of the bulging curved shelf provided on the front surface of the instrument panel of the automobile, when the front movable louver is shaken downward, the bulging curved shape However, it is possible to effectively prevent the sticking phenomenon of the wind that flows along the outer surface of the shelf part of the shelf and effectively blow the wind toward the front movable louver operated by the passenger. It can be carried out.

  Here, the front movable louver is provided with a lower auxiliary horizontal fin at the inner lower portion of the air outlet, and on both sides of the lower auxiliary horizontal fin, a support shaft is provided by being deviated downstream, and the lower auxiliary horizontal fin is provided. It is preferable to provide the said notch opening part in the downstream end part of a fin along the longitudinal direction of a fin. According to this, when the front movable louver is shaken down, the downward airflow flowing on the lower auxiliary lateral fin is blown obliquely upward through the notch opening and flows along the outer surface of the shelf. Easy air flow can be effectively changed away from the shelf.

Also here, in the register, the upper Symbol air outlet is formed in a shape constricted in the vertical cross-sectional shape of the flow path in the retainer at the distal end side, on the inside bottom of the air outlet, the flow An inclined surface that is inclined obliquely upward from the bottom surface of the road is provided, and when the front movable louver is directed downward during blowing, an air flow flows from the inclined surface through the notch opening of the lower auxiliary lateral fin, It can be configured to flow so as to push the wind upward.
Furthermore, in the register, the air outlet is horizontal transversely formed in a long vertical longitudinally shorter elongated, the front movable louver along the inside of the air outlet in the horizontal transverse direction arranged And
The front movable louver pivotally supports one central lateral fin at a substantially vertical center inside the air outlet so as to be pivotable in the horizontal lateral direction, while an upper auxiliary lateral fin is provided at the upper part inside the air outlet. It is pivotally supported so as to be rotatable in the horizontal lateral direction, and the lower auxiliary horizontal fin is pivotally supported in the lower part inside the air outlet so as to be rotatable in the horizontal horizontal direction.
The central horizontal fin, the upper auxiliary horizontal fin, and the lower auxiliary horizontal fin are pivotally supported by pivots that are deviated and protruded on the downstream side of both sides, and when the front movable louver is rotated. The central horizontal fin, the upper auxiliary horizontal fin, and the lower auxiliary horizontal fin can be configured to rotate together at the same angle.

  According to this, the shape of the air outlet of the register is an elongated shape that is long in the horizontal and horizontal directions and short in the vertical and vertical directions, which is likely to cause a phenomenon of wind flowing along the outer surface of the bulging curved shelf. Even with the formed resistor, when the front movable louver is shaken down, the air flow flowing along the front movable louver passes through the notched opening of the lower auxiliary lateral fin through the inclined surface inside the air outlet. By blowing air diagonally upward, the air flow that tends to flow along the outer surface of the shelf can be effectively changed to the direction away from the shelf.

  According to the register of the present invention, even when the register is installed at a portion where the bulging curved shelf is located in front of the air outlet of the air outlet, the outer shape of the shelf can be reduced with a simpler configuration than the conventional one. The phenomenon of wind sticking along the surface can be prevented and the directivity of the wind can be improved.

The vertical fins 4a are supported so as to be rotated in the left and right directions within a predetermined angle range. A bezel 1 having a substantially rectangular air outlet 15 formed in the front is formed in the front portion of the retainer 2 with the air outlet 15 aligned with the opening of the flow path 5. It is formed to communicate from the retainer 2 to the air outlet 15 of the bezel 1.

  As described above, the front movable louver 3 is disposed at one central lateral fin 7 that can be pivotally adjusted up and down, and above and below the central lateral fin 7. Accordingly, an upper auxiliary horizontal fin 8 and a lower auxiliary horizontal fin 9 that rotate up and down together with the central horizontal fin 7 are provided.

  The central lateral fin 7 is configured to have the widest fin body in the front movable louver 3, and support shafts 7 a project from both ends. As shown in FIGS. 1 and 2, one support shaft 7 a It penetrates the side wall of the flow path 5 and protrudes outside, and is supported rotatably. An operation knob 16 is externally fitted to the central lateral fin 7 so as to be slidable in the left and right longitudinal directions. The user holds the operation knob 16 and rotates the front movable louver 3 in the vertical direction. By sliding left and right, the direction of the rear movable louver 4 can be changed to the left and right.

  As shown in FIG. 2, a crank 11 is attached to the tip of one support shaft 7 a of the central lateral fin 7, and a link member 13 is connected to the crankshaft 12 in which the crank 11 is displaced. Similarly, the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 are respectively provided with support shafts 8a and 9a projecting on both sides, and one of the support shafts 8a and 9a protrudes outward through the side wall of the flow path 5, It is rotatably supported.

The link member 13 causes the central horizontal fin 7 and the upper auxiliary horizontal fin to be connected. 8 and the lower auxiliary horizontal fin 9 are interlocked with each other as shown in FIGS.

  As shown in FIG. 4, the lower auxiliary horizontal fin 9 of the front movable louver 3 has a notch opening 9b at the end of the fin body on the front side, that is, the downstream side where the support shaft 9a is located, and the longitudinal direction (horizontal horizontal direction) of the fin. It is formed along. By providing the notch opening 9b at the downstream end of the lower auxiliary horizontal fin 9, as shown in FIGS. 3 and 5, when the front movable louver 3 is rotated horizontally or obliquely downward, The air flow flowing through the bottom of the flow path 5 hits the inclined surface 1a inside the air outlet 15 of the bezel 1, and is blown out upward through the notch opening 9b. Thereby, it has the structure which acts so that the airflow which goes to the direction of the front movable louver 3 may be pushed up from the lower side.

  A rear movable louver 4 is disposed in the flow path 5 on the upstream side of the front movable louver 3, and a plurality of vertical fins 4a are vertically arranged in the rear movable louver 4 at regular intervals on the left and right. The Each vertical fin 4a is provided with a support shaft 4b at the upper and lower portions, and the upper and lower support shafts 4b are supported by bearings provided on the upper and lower walls of the flow path 5 and can be rotated in conjunction with the left and right. It is supported by.

  As shown in FIGS. 1 and 2, an operation knob 16 is fitted on the central lateral fin 7 so as to be slidable in the left-right longitudinal direction, and the central lateral fin 7 is rotated in the vertical direction by holding the operation knob 16. By operating the front movable louver 3 so that the vertical direction of the front louver 3 can be rotated and the operation knob 16 is slid in the left-right direction, the rear movable louver 4 is swung left and right to change the wind direction to the left and right. Yes.

  For this reason, although not shown in the drawings, the rear portion of the operation knob 16 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 support shaft 4b of the vertical fin 4a, and the crankshafts of the cranks are connected to each other by a single link bar. Thus, when the operation knob 16 is slid left and right on the central horizontal fin 7, the vertical fins 4a of the rear movable louver 4 are rotated to the left and right in conjunction with each other to change the wind direction to the left and right.

  Next, the operation of the register having the above configuration will be described with reference to FIGS. The register is attached, for example, in the vicinity of the upper portion of an instrument panel or dashboard in an automobile, with an air inlet on the back side connected to a ventilation duct (not shown). As shown in FIG. 3, the air outlet 15 of the register is exposed on the front surface of the instrument panel or dashboard, and has a curved surface that bulges out to the passenger side on the lower front side of the air outlet 15. The shelf 20 is provided on an instrument panel or the like. That is, the register air outlet 15 is located above the portion where the bulging and curved shelf 20 such as an instrument panel or dashboard is provided, and the register is installed.

  When air is blown straight in front of the register, the front movable louver 3 is set in a horizontal state, that is, in a state facing straight forward as shown in FIG. In this state, the central horizontal fin 7, the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 of the front movable louver 3 are all kept horizontal, and the air flow flowing through the flow path 5 is the central horizontal fin 7 and the upper auxiliary horizontal fin. It is guided by the fins 8 and the lower auxiliary horizontal fins 9 and is blown in the horizontal front direction. At this time, as shown in FIG. 3, the airflow flowing through the bottom (lower part) of the flow path 5 hits the inclined surface 1 a, passes through the cutout opening 9 b of the lower auxiliary lateral fin 9 from the bottom to the top, and the air outlet 15 It hits the main wind blown through the air and acts to reduce the air flow. For this reason, the wind which has been shrunk from the register is blown to the occupant, and the occupant can be supplied with a wind with a spot feeling.

  On the other hand, when the operation knob 16 on the central lateral fin 7 of the front movable louver 3 is operated to rotate the front movable louver 3 downward as shown in FIG. 5, the central lateral fin 7, the upper auxiliary lateral fin 8 and The lower auxiliary horizontal fin 9 rotates so as to face obliquely downward.

  As a result, the air flow flowing from the flow path 5 toward the air outlet 15 is guided by the central horizontal fin 7, the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 which are all directed obliquely downward as shown in FIG. 5. Then, the air is blown obliquely downward from the air outlet 15.

  When the bulging and curved shelf 20 is located on the lower front side of the air outlet 15, the wind tends to flow along the outer surface of the shelf 20 due to the Coanda effect of the fluid. However, in the register of the present invention, as shown in FIG. 5, the air flow flowing through the bottom of the flow path 5 hits the inclined surface 1 a on the inner lower side of the air outlet 15, so The air is blown toward the mainstream air guided by the front movable louver 3 through 9b, and acts to push the mainstream air upward. As a result, the wind flowing along the outer surface of the shelf 20 is peeled off from the surface, and air can be blown correctly toward the chest, waist, etc. of the passenger, which is the operation direction of the front movable louver 3.

  Thus, even when the bulging and curved shelf 20 is positioned on the lower front side of the air outlet 15, it is easy to simply provide the notch opening 9 b in the lower auxiliary lateral fin 9 of the front movable louver 3. With this structure, it is possible to prevent the phenomenon of wind flowing along the outer surface of the bulging curved shelf 20 when the front movable louver 3 is rotated downward, and to adjust the front movable louver. It is possible to improve the directionality of the wind by appropriately blowing air in the direction of 3.

  On the other hand, when the operation knob 16 on the central lateral fin 7 of the front movable louver 3 is operated to rotate the front movable louver 3 upward as shown in FIG. 6, the central lateral fin 7, the upper auxiliary lateral fin 8 and The lower auxiliary horizontal fins 9 rotate so as to face obliquely upward at the same angle. Thereby, when passing through the front movable louver 3, the air flow flowing through the flow path 5 is guided upward and blown obliquely upward from the air outlet 15.

  In the above embodiment, the front movable louver 3 is provided with the central horizontal fin 7, the upper auxiliary horizontal fin 8, and the lower auxiliary horizontal fin 9, but the fins of the front movable louver are a plurality of fins that rotate in conjunction with each other. If so, a plurality of horizontal fins having the same shape may be arranged in a rotatable manner, or a plurality of vertical fins may be arranged in a rotatable manner. Moreover, although the said air blower outlet 15 was inclined and formed so that upper part might reverse | retreat to an upstream side and the lower part protruded downstream, it can also be set as a vertical air blower outlet, without inclining.

  In the above-described embodiment, the register having the flat air outlet 15 which is formed in a flat and elongated rectangle and is long in the horizontal and horizontal directions and short in the vertical and vertical directions has been described. However, the air outlet 15 is rotated by 90 degrees. The present invention can also be applied to a register having a vertically long air outlet that is long in the vertical direction and short in the horizontal and horizontal direction. In this case, the front movable louver has a plurality of vertically long fins, and a register is disposed at a position where the bulging curved shelf is disposed in front of the side portion of the air outlet, and the front movable louver is located on the side. When it is swung to the side, it is possible to prevent the phenomenon that the wind swung to the side flows along the bulging curved shelf in front of the side portion.

  7 to 10 show the register of the second embodiment. As shown in FIG. 9, this register is provided with a ridge 29 b on the lower auxiliary lateral fin 29 disposed on the inner side of the air outlet 15 on the front movable louver 23. When it is swung, the air flow guided by the ridges 29b acts on the mainstream wind to prevent the wind from sticking to the shelf 20. Note that components similar to those in the register are denoted by the same reference numerals in FIGS. 7 to 10 and description thereof is omitted.

  As shown in FIG. 7, the front movable louver 23 is arranged at one central lateral fin 27 that can be pivoted up and down, and above and below the central lateral fin 27. An upper auxiliary horizontal fin 28 and a lower auxiliary horizontal fin 29 that rotate up and down together with the central horizontal fin 27 according to an operation are provided.

  The central lateral fin 27 is configured to have the widest fin body in the front movable louver 23, and a support shaft 27 a protrudes from both ends. One support shaft 27 a penetrates the side wall of the flow path 5 and is outside. And is supported so as to be rotatable. An operation knob 16 is fitted on the central lateral fin 27 so as to be slidable in the left and right longitudinal directions, and the user holds the operation knob 16 and rotates the front movable louver 23 in the vertical direction. By sliding left and right, the direction of the rear movable louver 4 can be changed to the left and right.

  In addition, a crank is pivotally attached to the tip of one of the support shafts 27a of the central lateral fin 27, and a link member is connected to the crankshaft in which the crank is displaced, as shown in FIG. The Similarly, each of the upper auxiliary horizontal fin 28 and the lower auxiliary horizontal fin 29 has support shafts 28a and 29a projecting on both sides, and one of the support shafts 28a and 29a penetrates the side wall of the flow path 5 and projects outward. It is rotatably supported. Also, a crank is pivotally attached to the tip of one of the support shafts 28a, 29a, and the crankshaft whose crank is displaced is connected to a link member, and the central lateral fin 27, the upper auxiliary horizontal fin 28, and the lower auxiliary are connected by the link member. The horizontal fins 29 are interlocked to rotate at the same angle in the vertical direction.

  As shown in FIG. 8, the lower auxiliary horizontal fin 29 of the front movable louver 23 has a protrusion 29b on the upper surface of the end portion on the front side where the support shaft 29a is located, that is, on the downstream side of the fin body. It is formed along. By providing the ridge 29b on the downstream end of the lower auxiliary horizontal fin 29, as shown in FIG. 9, when the front movable louver 23 is rotated obliquely downward, the airflow flowing through the flow path 5 is increased. The ridges 29b are bent upward and blown. Thus, the air flow guided downward toward the front movable louver 23 acts to push up from below.

  Further, on the upper auxiliary horizontal fin 28 of the front movable louver 23, a protrusion 28b extends along the longitudinal direction (horizontal horizontal direction) of the fin on the front side where the support shaft 28a is located, that is, on the downstream side of the end of the fin main body. Is formed. By providing the protrusion 28b below the end portion on the downstream side of the upper auxiliary horizontal fin 28, as shown in FIG. 7, when the front movable louver 23 is in a horizontal state, it passes below the upper auxiliary horizontal fin 28. The air flow is pushed down by the ridges 28b, and the main wind is contracted.

  Next, the operation of the register having the above-described configuration will be described with reference to FIGS. 7 to 10. The register is attached with the air outlet 15 exposed on the front surface of the instrument panel or the dashboard as described above. A shelf 20 having a curved surface that bulges so as to protrude toward the occupant is provided on the instrument panel or the like on the lower front side of the air outlet 15. In other words, the register air outlet 15 is located above the portion where the bulging and curved shelf 20 such as an instrument panel or dashboard is provided, and the register is installed.

  When air is blown straight in front of the register, as shown in FIG. 7, the front movable louver 23 is set in a horizontal state, that is, in a state facing straight forward. In this state, the central horizontal fin 27, the upper auxiliary horizontal fin 28, and the lower auxiliary horizontal fin 29 of the front movable louver 23 are all kept horizontal, and the airflow flowing through the flow path 5 is the central horizontal fin 27, the upper auxiliary horizontal fin. It is guided by the fins 28 and the lower auxiliary horizontal fins 29 and is blown in the horizontal front direction. At this time, as shown in FIG. 7, the air flow flowing below the upper auxiliary horizontal fins 28 of the front movable louver 23 acts to push down the upper part of the main flow, while the air flow flowing above the lower auxiliary horizontal fins 29. Acts to push up the lower part of the mainstream. As a result, the mainstream air flow blown through the air outlet 15 is contracted, the contracted wind is blown to the passenger, and a spot-like wind can be supplied to the passenger.

  On the other hand, when the operation knob 16 on the central lateral fin 27 of the front movable louver 23 is operated to rotate the front movable louver 23 downward as shown in FIG. 9, the central lateral fin 27, the upper auxiliary lateral fin 28, and The lower auxiliary horizontal fin 29 rotates so as to face obliquely downward.

  As a result, the airflow flowing from the flow path 5 toward the air outlet 15 is guided by the central horizontal fin 27, the upper auxiliary horizontal fin 28, and the lower auxiliary horizontal fin 29, all of which are directed obliquely downward, as shown in FIG. Then, the air is blown obliquely downward from the air outlet 15.

  When the bulging and curved shelf 20 is located on the lower front side of the air outlet 15, the wind tends to flow along the outer surface of the shelf 20 due to the Coanda effect of the fluid. However, in this register, as shown in FIG. 9, the air flow that passes through the front movable louver 23 is blown by the air flow that particularly flows above the lower auxiliary lateral fin 29 being bent upward by the ridges 29b on the upper surface. And acts to push the mainstream wind upward. As a result, the wind that flows along the outer surface of the shelf 20 is peeled off from the surface, and the air can be blown correctly toward the chest, waist, etc. of the passenger below the operation direction of the front movable louver 23. it can.

  Thus, even when the bulging and curved shelf 20 is located on the lower front side of the air outlet 15, it is easy to simply provide the ridge 29 b on the lower auxiliary lateral fin 29 of the front movable louver 23. With this simple structure, it is possible to prevent the phenomenon of sticking of the wind flowing along the outer surface of the bulging curved shelf 20 when the front movable louver 23 is rotated downward, and the adjusted front movable louver It is possible to improve the directivity of the wind by appropriately blowing air in the direction of 23.

  On the other hand, when the operation knob 16 on the central lateral fin 27 of the front movable louver 23 is operated to rotate the front movable louver 23 upward as shown in FIG. 10, the central lateral fin 27, the upper auxiliary lateral fin 28, and The lower auxiliary horizontal fins 29 rotate so as to face obliquely upward at the same angle. Thereby, when passing through the front movable louver 23, the airflow flowing through the flow path 5 is guided upward and is blown obliquely upward from the air outlet 15. At this time, as shown in FIG. 10, the air flow flowing below the upper auxiliary horizontal fin 28 of the front movable louver 23 acts to push down the upper part of the main flow, and the air flow flowing above the lower auxiliary horizontal fin 29 is the main flow. The main air flow blown through the air outlet 15 is contracted, the contracted wind is blown to the passenger, and a wind with a spot feeling is supplied to the passenger. can do.

As shown in FIGS. 11 to 13, this register is different from the front movable louver 33 disposed inside the air outlet 15 in that the central horizontal fin 37, the upper auxiliary horizontal fin 38 and the lower auxiliary horizontal fin 39 are different. In particular, when the front movable louver 33 is swung down, the lower auxiliary lateral fin 39 is rotated at a shallower angle (small angle θ5) than the other fins, and the lower auxiliary The air flow guided by the horizontal fins 39 is caused to act on the mainstream wind, thereby preventing the wind from sticking to the shelf 20. Note that components similar to those in the register are denoted by the same reference numerals in FIGS. 11 to 13 and description thereof is omitted.

  In the same manner as above, this register has an oblong air outlet 15 formed in the front of the bezel 1, and the air outlet 15 is formed into a flat and elongated rectangle, and is long and short in the longitudinal direction (horizontal lateral direction). It is formed in a horizontally long rectangle that is short in the direction (vertical and vertical directions). Further, the air outlet 15 on the front side of the register is formed so as to be inclined so that the upper part is retreated to the upstream side and the lower part is protruded to the downstream side, and the front face of the air outlet 15 is formed with respect to the vertical surface in the short direction. It is inclined so that its upper part is retracted backward at an angle of about 25 degrees, and has a so-called slant shape. Further, the air outlet 15 at the tip of the bezel 1 is formed so that the cross-sectional shape of the base portion of the bezel 1 and the flow path 5 of the retainer 2 is narrowed up and down on the tip side.

  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. A front movable louver 33 is disposed immediately inside the air outlet 15 of the bezel 1 so as to change the wind direction up and down.

  The central horizontal fin 37, the upper auxiliary horizontal fin 38, and the lower auxiliary horizontal fin 39 have a structure in which each fin rotates at each angle when the front movable louver 33 is rotated up and down. Further, the front and rear positions of the central horizontal fin 37, the upper auxiliary horizontal fin 8, and the lower auxiliary horizontal fin 39 of the front movable louver 33 are matched with the inclined state of the air outlet 15 as shown in FIG. The upper auxiliary horizontal fin 38 is shifted to the upstream side, and the lower auxiliary horizontal fin 39 is shifted to the downstream side.

  The retainer 2 is formed in a substantially square duct shape, and a ventilation flow path 5 is formed therein. Bearing portions are formed at predetermined intervals on the upper wall and the lower wall of the downstream edge of the retainer 2, and the rear movable louver 4 on the upstream side (rear portion) of the front movable louver 33 is provided on the vertical fin 4 a. The support shaft 4b is pivotally supported. The plurality of vertical fins 4a of the rear movable louver 4 are configured to rotate in conjunction with the left and right within a predetermined angle range. A bezel 1 having a substantially rectangular air outlet 15 formed in the front is formed in the front portion of the retainer 2 with the air outlet 15 aligned with the opening of the flow path 5. It is formed to communicate from the retainer 2 to the inside.

  The front movable louver 33 is disposed immediately inside the air outlet 15 in the bezel 1, and can be adjusted to rotate up and down and has a single central horizontal fin 37 having the widest front-rear width, An upper auxiliary lateral fin 38 disposed at a lower position and pivoted at a different angle from the central lateral fin 37 according to the pivoting operation of the central lateral fin 37 and having a front and rear width smaller than the central lateral fin 37. A lower auxiliary lateral fin 39.

  As described above, the air outlet 15 is formed in an elongated shape that is long in the horizontal horizontal direction and short in the vertical and vertical directions, and the front movable louver 33 is disposed inside the air outlet 15 along the horizontal horizontal direction. The front movable louver 33 pivotally supports one central lateral fin 37 having a wide front and rear width in a horizontal lateral direction at a substantially vertical center inside the air outlet 15. Further, an upper auxiliary lateral fin 38 having a small front-rear width is pivotally supported in the upper part inside the air outlet 15 so as to be rotatable in the horizontal lateral direction, and a lower auxiliary having a small front-rear width is provided in the lower part inside the air outlet 15. The lateral fin 39 is pivotally supported so as to be rotatable in the horizontal lateral direction.

  The support shafts 37a, 38a, 39a on one side of the central horizontal fin 37, the upper auxiliary horizontal fin 38, and the lower auxiliary horizontal fin 39 protrude outward from the side wall, and a fin rotation mechanism (not shown) is provided on the outer side. . This fin rotation mechanism is composed of, for example, a cam mechanism or a link mechanism, and when the user operates the operation knob 16 to rotate the front movable louver 33 (central lateral fin 37) downward, FIG. As shown, the lower auxiliary horizontal fin 39 rotates so as to be at a shallower angle (smaller downward angle θ5) than the downward angle (θ3, θ4) of the central horizontal fin 37 and the upper auxiliary horizontal fin.

  Further, when the front movable louver 33 (central lateral fin 37) is in a horizontal state, as shown in FIG. 11, the upper auxiliary lateral fin 38 faces obliquely downward at a small downward angle θ1, and the lower auxiliary lateral fin 39 is small downward. The fin rotation mechanism is configured to face obliquely upward at an angle θ2. Further, when the front movable louver 33 (central lateral fin 37) is turned upward, as shown in FIG. 13, the central lateral fin 37 and the lower auxiliary lateral fin 39 are directed obliquely upward at upward angles θ7 and θ9. The fin rotation mechanism is configured such that the auxiliary lateral fin 38 faces upward at a shallower angle (small upward angle θ8).

  The rear movable louver 4 is disposed in the flow path 5 on the upstream side of the front movable louver 33 in the same manner as described above, and a plurality of vertical fins 4a are vertically arranged at regular intervals on the left and right sides of the rear movable louver 4. Side by side. Each vertical fin 4a is provided with a support shaft 4b at the upper and lower portions, and the upper and lower support shafts 4b are supported by bearings provided on the upper and lower walls of the flow path 5 and can be rotated in conjunction with the left and right. It is supported by.

  An operation knob 16 is fitted on the central lateral fin 37 so as to be slidable in the left-right longitudinal direction. The operation knob 16 is gripped and the central lateral fin 37 is rotated up and down to move the front movable louver 33 up and down. Can be rotated and the operation knob 16 is slid in the left-right direction to swing the rear movable louver 4 to the left and right to change the wind direction to the left and right.

  Although not shown, the rear portion of the operation knob 16 is provided with an engaging portion that engages with one vertical fin 4a of the rear movable louver 4, and all the vertical fins 4a including the vertical fin 4a are provided. A crank (not shown) is pivotally attached to the support shaft 4b, and the crankshafts of the cranks are connected to each other by a single link bar. Thus, when the operation knob 16 is slid left and right on the central lateral fin 37, the vertical fins 4a of the rear movable louver 4 are rotated to the left and right in conjunction with each other, and the wind direction is changed to the left and right.

  Next, the operation of the register having the above configuration will be described with reference to FIGS. Similarly to the above, the register is mounted with the air outlet 15 exposed on the front surface of the instrument panel or dashboard, and a curved surface that protrudes toward the occupant side is formed on the lower front side of the air outlet 15. The shelf 20 is provided on an instrument panel or the like. That is, the register air outlet 15 is located above the portion where the bulging and curved shelf 20 such as an instrument panel or dashboard is provided, and the register is installed.

  When air is blown straight in front of the register, the front movable louver 33 (central lateral fin 37) is set in a horizontal state, that is, in a state facing straight forward as shown in FIG. In this state, the upper auxiliary horizontal fin 38 of the front movable louver 33 faces obliquely downward at a small angle θ1 (inclination angle with respect to the horizontal line), and the lower auxiliary horizontal fin 39 faces obliquely upward at a small angle θ2. Thus, the air flow flowing through the flow path 5 is guided by the central horizontal fin 27 and blown straight forward from the air outlet 15 in the horizontal front direction, and the air flow flowing below the upper auxiliary horizontal fin 38 is the mainstream wind. The air flow that flows above the lower auxiliary lateral fin 39 acts to push up the lower part of the main wind. Thereby, the mainstream wind blown through the air outlet 15 is contracted, and the contracted wind is sent to the occupant, so that the occupant can be supplied with a spot-like wind.

  On the other hand, when the operation knob 16 on the central lateral fin 37 of the front movable louver 33 is operated to rotate the front movable louver 33 downward as shown in FIG. 12, the central lateral fin 37 and the upper auxiliary lateral fin 38 are moved. The lower auxiliary horizontal fins 39 are turned obliquely downward at angles θ3 and θ4 (inclination angles with respect to the horizontal line), and the lower auxiliary horizontal fins 39 are directed obliquely downward at a smaller angle θ5 (shallow inclination angle with respect to the horizontal line).

  Thereby, as shown in FIG. 12, the air flow flowing from the flow path 5 toward the air outlet 15 is guided by the central horizontal fin 37 and the upper auxiliary horizontal fin 38 both facing obliquely downward, and the air outlet 15 The air is blown diagonally downward. On the other hand, since the lower auxiliary horizontal fin 39 faces downward at a shallower angle (angle θ5 smaller than the angles θ3 and θ4), the main wind blown by being guided by the central horizontal fin 37 and the upper auxiliary horizontal fin 38 is lower. The air will be blown so as to push up.

  That is, when the bulging and curved shelf 20 is located on the lower front side of the air outlet 15, the wind tends to flow along the outer surface of the shelf 20 due to the Coanda effect of the fluid. However, in this register, as shown in FIG. 12, the airflow passing through the front movable louver 33 is bent upward and the airflow flowing on the upper side of the lower auxiliary lateral fin 39 is blown upward. As a result, the wind that flows along the outer surface of the shelf 20 is peeled off from the surface, and is directed toward the passenger's chest and waist below the operation direction of the front movable louver 33. The air can be blown correctly.

  Thus, even when the bulging and curved shelf 20 is located on the lower front side of the air outlet 15, the downward angle of the lower auxiliary lateral fin 39 of the front movable louver 33 is set to a shallower angle θ5. By doing so, it is possible to prevent the phenomenon of the wind flowing along the outer surface of the bulging curved shelf 20 during the downward rotation of the front movable louver 33, and the adjusted front movable louver It is possible to improve the directivity of the wind by appropriately blowing air in the direction 33.

  On the other hand, when the operation knob 16 on the central lateral fin 37 of the front movable louver 33 is operated to rotate the front movable louver 33 upward as shown in FIG. 13, the central lateral fin 37 and the lower auxiliary lateral fin 39 are moved. Both the upper auxiliary lateral fins 38 are rotated obliquely upward at the same angle θ7 and θ9, and the upper auxiliary lateral fin 38 is rotated obliquely upward at a shallower angle (smaller angle θ8). As a result, the air flow flowing through the flow path 5 is guided upward when passing through the front movable louver 33 and is blown obliquely upward from the air outlet 15. At this time, as shown in FIG. The airflow flowing below the upper auxiliary lateral fin 38 of the louver 33 acts to push down the upper part of the main wind. For this reason, the mainstream airflow blown through the air outlet 15 is contracted, and the contracted wind is blown to the passenger, so that the passenger can be supplied with a spot-like wind.
