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 longitudinal direction and short in the lateral direction, and the air outlet is located inside the air outlet. The present invention relates to a register suitable for a register having a structure having a small number of fins parallel to the longitudinal direction.

  As a register for adjusting the air blowing of an automobile, a horizontally movable louver and a longitudinally movable louver are arranged in front and back in a retainer that forms a ventilation path. When blowing air from an air outlet provided in a bezel, a horizontally movable louver A register that adjusts the air blowing direction by changing the angle of each fin of the longitudinally movable louver is used.

By the way, 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

  Since the air blower outlet has an elongated shape that is long in the longitudinal direction and short in the lateral direction, the number of movable fins that are long in the longitudinal direction is inevitably as small as 1 to 3. Thus, the number of fins is smaller than that of a normal movable louver of a register.

  However, in a register having a long and narrow air outlet in the longitudinal direction of the fin, when the number of fins along the longitudinal direction is as small as, for example, about 1 or 2, the direction of the fin is reduced to the short side of the elongated air outlet. Even if the direction is changed up and down or left and right along the direction, it is difficult to sufficiently change the direction of the wind in that direction, and there is a problem that the directivity of the wind is poor.

  That is, in a register provided with an elongated air outlet 33 that is long in the longitudinal direction and short in the lateral direction, as shown in FIG. 9, when the number of fins 31 of the front movable louver 30 is a small number of about 1 to 3, The air flow is narrowed in the short direction (vertical direction in FIG. 9) in the short ventilation path 32 in the short direction, and is further restricted by the air resistance by the fins 31.

  For this reason, when passing through the ventilation path 32, the air flow having a certain level of blowing pressure is throttled in the short direction, and is accelerated and blown out in the linear direction. For this reason, even if a small number of fins 31 such as one or two sheets are changed upward or downward, as shown in FIG. The bending condition is strong and easily affected. For this reason, the wind is difficult to bend in the direction in which the fins 31 face, and when the direction of the fins 31 of the front movable louver 30 is changed, there is a problem that the directivity of the wind tends to deteriorate.

  The present invention has been made in view of the above points, and has a long and narrow air outlet and a resistor provided with a small number of fins inside the air outlet in parallel with the longitudinal direction. It is an object of the present invention to provide a register that can effectively improve the directivity of wind when the direction of fins is changed.

  In order to achieve the above object, in the register of the present invention, a front movable louver is disposed inside the air outlet at the front end of the ventilation path, and a fin orthogonal to the fin of the front movable louver is disposed behind the front movable louver. In the register having the rear movable louver, the plurality of fins orthogonal to the fins of the front movable louver are pivotally supported in the rear movable louver so as to be rotatable in the barrel. The barrel is pivotally supported around an axis parallel to the fin of the louver, and the barrel is rotated in the same direction as the fin in synchronization with the rotation of the fin of the front movable louver when the front movable louver is rotated. It is characterized in that an associated rotation mechanism for rotating the is arranged.

  Here, the air outlet is formed in an elongated shape along the longitudinal direction of the fins of the front movable louver, and one to three fins are provided in the front movable louver in parallel with the longitudinal direction of the air outlet. Can be arranged.

  Further, the barrel is formed by providing shaft portions for pivotally supporting the frame-shaped main body on the short frame portions on both sides of a rectangular frame-shaped main body similar to the air outlet, A plurality of fin shafts can be supported between the longitudinal frame portions and the longitudinal frame portions on both sides of the main body.

  Further, the linkage rotation mechanism is configured by providing a gear on the fin shaft of the front movable louver and linking a gear provided on the shaft portion of the barrel to a gear on the front movable louver side via an intermediate gear. can do.

  Further, an operation knob is slidably attached to the fin of the front movable louver, and the rear portion of the operation knob is engaged with the fin of the rear movable louver in the barrel, so that the operation knob is It can be set as the structure which rotates the fin of a rear movable louver by sliding.

  The register having the above configuration adjusts the blowing direction of the wind, for example, by operating an operation knob mounted on the fin of the front movable louver. When the fins of the front movable louver are arranged horizontally and horizontally, the operation knob mounted on the fins is operated to rotate the fins up and down to adjust the direction of the wind upward or downward. At this time, as the fin of the front movable louver rotates, the barrel rotates in the same direction as the fin via the linkage rotation mechanism in synchronization with the rotation of the fin.

  When the operation knob is operated and the fin of the front movable louver is directed obliquely downward, the barrel faces obliquely downward, and when the fin of the front movable louver is directed obliquely upward, the barrel faces obliquely upward. Thereby, the longitudinal frame portion of the barrel is in a state of guiding the wind passing through the vicinity of the upper wall or the lower wall of the ventilation path obliquely upward or obliquely downward.

  Therefore, the air flow that blows straight through the gap between the fin of the front movable louver and the upper wall or between the fin and the lower wall in a straight line as in the past is prevented, and the wind is directed in the direction toward the fin of the front movable louver. Can be blown out well, and the directivity of the wind by the fins of the front movable louver can be greatly improved.

  In particular, in the case of a register having an elongated air outlet in the longitudinal direction and a small number (for example, 1 to 3) of fins provided in the front movable louver in parallel to the longitudinal direction inside the air outlet, the front movable louver The directivity of the wind can be effectively improved without increasing the width of the fins, and the pressure loss of the blast and noise due to the airflow can be suppressed by reducing the width of the fins.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 shows a perspective view of the register, FIG. 2 shows a longitudinal sectional view thereof, and FIG. 3 shows a transverse sectional view thereof. In these drawings, reference numeral 1 denotes a bezel having a substantially rectangular air outlet 1a formed in the front. As shown in FIGS. 1 and 2, the air outlet 1 a is formed in an elongated slit shape, and is formed in a horizontally long rectangular shape that is long in the longitudinal direction and short in the lateral direction.

  A fitting portion for connecting to the retainer 2 is provided on the inner side (back side) of the bezel 1, and the duct-like retainer 2 is fitted and connected to the fitting portion. Bearing portions of the front movable louver 3 are formed on the left and right side walls inside the air outlet 1 a of the bezel 1, and the rotating shaft 14 of the lateral fin 13 of the front movable louver 3 is supported by the bearing portion. A rubber-like elastic body 14a is attached to the rotation shaft 14 to give an appropriate rotation resistance.

  The retainer 2 is formed in a duct shape having a substantially square cross section, and an air passage 2a is formed therein. A barrel 10 is pivotally supported in the ventilation path 2a of the retainer 2 so as to be rotatable about a horizontal and horizontal axis. The both side walls of the retainer 2 are provided to protrude on both the left and right sides of the barrel 10. A bearing portion that pivotally supports the shaft portion 12 is formed, and the shaft portion 12 is supported by the bearing portion. As shown in FIG. 3, the front portion of the retainer 2 is formed to be inclined left and right so that the left portion protrudes forward and the right portion is lowered rearward, and a substantially rectangular shape is formed at the inclined front end portion. The bezel 1 having the air outlet 1a formed as an opening is fitted in a state where the air outlet 1a is aligned with the opening of the air passage 2a.

  The front movable louver 3 includes one horizontal fin 13 and an operation knob 5 that is slidably fitted on the horizontal fin 13. As shown in FIG. 4, the horizontal fins 13 have pivot shafts 14 projecting at both ends, and the pivot shafts 14 on both sides of the horizontal fins 13 are inserted into bearing portions on both side walls of the bezel 1 or the retainer 2. , Supported in a pivotable manner. As described above, the operation knob 5 is fitted on the horizontal fin 13 so as to be slidable left and right.

  The operation knob 5 is formed so that the knob body 5a has a substantially U-shaped side surface, and the knob rear part 5b is fitted to the rear part of the knob body 5a. The knob rear portion 5b has two protrusions, and an engagement convex portion 5c protrudes rearward so as to be engageable with an engagement portion 15a of a vertical fin 15 of the rear movable louver 4 described later. In addition, a rubber-like elastic body 5d is disposed in the knob main body 5a so as to be slidable on the front portion of the lateral fin 13 so as to apply an operation load. It has a structure that generates a load.

  Such an operation knob 5 is slidably fitted on the horizontal fin 13, and when the operation knob 5 is operated so as to be pushed down with a finger or the like, the horizontal fin 13 of the front movable louver 3 is tilted downward, and obliquely below Can be directed. On the other hand, when the operation knob 5 is slid right or left on the horizontal fin 13, the engagement convex portion 5 c at the rear portion of the operation knob 5 is engaged with the engagement portion 15 a of the vertical fin 15 of the rear movable louver 4, The vertical fin 15 rotates to the right or left.

  Further, as shown in FIGS. 2 to 4, a fan-shaped gear 21, which is a part of the linkage rotation mechanism 20, is attached to the left rotation shaft 14 of the horizontal fin 13 to rotate the horizontal fin 13. Accordingly, the gear 21 rotates. The gear 21 meshes with the intermediate gear 22, and the intermediate gear 22 further meshes with a fan-shaped gear 23 that is pivotally attached to the shaft portion 12 of the barrel 10. As a result, the gear 21 transmits the rotation of the rotation shaft 14 of the horizontal fin 13 to the gear 23 of the barrel 10 via the intermediate gear 22 and transmits the rotation in the same direction as the gear 21 to the shaft portion 12 of the barrel 10. It has a structure to do. The linkage rotation mechanism 20 includes a gear 21, an intermediate gear 22, and a gear 23.

  As shown in FIG. 4, the barrel 10 has a frame-shaped main body 11 formed in a substantially rectangular frame shape having the same shape as the transverse cross-sectional shape of the ventilation path 2 a. The frame-shaped main body 11 is formed by integrally forming a left and right short frame portion 11a and an upper and lower long frame portion 11b, and a shaft portion 12 protrudes horizontally from the center outside of the left and right short frame portions 11a. . A fan-shaped gear 23 is attached to the left shaft portion 12.

  On the other hand, the upper and lower longitudinal frame portions 11b of the frame-like main body 11 of the barrel 10 are provided with axial holes for vertical fins at predetermined intervals, and the vertical fins 15 of the rear movable louver 4 are arranged at the upper and lower sides thereof. The rotation shaft 16 is rotatably fitted in each shaft hole of the longitudinal frame portion 11b. Each vertical fin 15 engages a frame-like engagement portion 15a provided on the second vertical fin 15 from the right with an engagement convex portion 5c of the operation knob 5, and when the operation knob 5 slides left and right, The direction of the fin 15 is changed to right and left. The engaging portion 15a of the vertical fin 15 can be a fan-shaped gear portion, and the engaging convex portion 5c of the operation knob 5 can be a rack-like tooth portion.

  As shown in FIG. 4, rotating shafts 16 project from the upper and lower portions of the respective vertical fins 15 of the rear movable louver 4, and these rotating shafts 16 are respectively axial holes of the longitudinal frame portion 11 b of the barrel 10. It is fitted to be rotatable. Further, eccentric shafts 17 project from the eccentric positions below the vertical fins 15, and these eccentric shafts 17 are connected to each other by a link bar 18. By this link mechanism, the vertical fins 15 of the rear movable louver 4 rotate so as to change their directions all at once.

  The shaft portions 12 projecting from the short frame portions 11a on both sides of the barrel 10 are provided with wall portions on both sides in the retainer 2 in a state where rubber-like elastic bodies 12a are mounted in order to give an appropriate rotational resistance. It is rotatably supported by the bearing part provided in. In this state, the gear 23 of the shaft portion 12 on the left side of the barrel 10 is located outside the retainer 2 and meshes with the intermediate gear 22 that is pivotally attached to the side surface of the retainer 2. The intermediate gear 22 meshes with the gear 21 of the lateral fin 13.

  Therefore, when the operation knob 5 is operated up and down to rotate the horizontal fin 13 upward or downward, the barrel 10 is connected to the horizontal fin 13 via the gear 21, the intermediate gear 22, and the gear 23 of the linkage rotation mechanism 20. Rotate in the same direction. That is, when the horizontal fin 13 is tilted (rotated) upward, the barrel 10 tilts upward, and when the horizontal fin 13 is tilted downward, the barrel 10 tilts downward.

  A damper plate 8 is pivotally supported behind the rear movable louver 4 in the ventilation path 2 a of the retainer 2 through a pivot shaft provided at both ends, and the ventilation path 2 a is rotated by the rotation of the damper plate 8. It is the structure which opens and closes. The left rotation shaft 8a of the damper plate 8 is fitted into a shaft hole provided in the side wall of the retainer 2, and the damper shaft 19 with the link lever 19a is fitted into the shaft hole provided in the right side wall of the retainer 2 from the outside. Worn. The damper plate 8 is rotatably supported by the rotation shaft 8a and the damper shaft 19. A long hole 19b is formed in the link lever 19a of the damper shaft 19, and a later-described pin 9b on the damper knob 9 side is fitted into the long hole 19b.

  As shown in FIGS. 3 and 4, the damper knob 9 is pivotally supported at the right end portion of the front portion of the retainer 2 so as to be rotatable, and is disposed so as to be exposed forward from an opening portion 1 b provided at the right end of the bezel 1. The damper knob 9 has a substantially fan-shaped knob body, and a rubber-like elastic body 9c having a shaft hole is fitted to a boss portion at the axial center position to apply an operation load. The damper knob 9 is pivotally supported by fitting the shaft hole of the rubber-like elastic body 9c to a knob shaft protruding from the right end of the retainer front portion. A lever portion 9a is integrally formed at the end of the knob main body of the damper knob 9, and a pin 9b projects from the tip of the lever portion 9a. The pin 9 b engages with the long hole 19 b of the link lever 19 a of the damper shaft 19. Thus, when the damper knob 9 is rotated up or down, the damper plate 8 rotates about the rotation shaft 8a and the damper shaft 19 to open or close the ventilation path 2a.

  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 retainer 2 is connected to a ventilation duct (not shown). The air sent from the ventilation duct is blown out from the ventilation path 2a in the retainer 2 through the air outlet 1a.

  As shown in FIG. 2, in the state in which the horizontal fins 13 of the front movable louver 3 and the vertical fins 15 of the rear movable louver 4 are parallel to the air blowing direction of the ventilation path 2a, the air flow proceeds substantially straight in the ventilation path 2a. Then, it passes between the vertical fins 15 and the horizontal fins 13 and is blown forward from the air outlet 1a.

  When adjusting the air blowing direction to the left and right, the operation knob 5 is moved to the left or right for adjustment. When the control knob 5 is held and moved to the left or right, the control knob 5 slides on the horizontal fin 13 and moves in the horizontal direction (left and right horizontal direction). Accordingly, as shown in FIGS. 7 and 8, the engagement convex portion 5 c at the rear portion of the operation knob 5 is engaged with the engagement portion 15 a of one vertical fin 15 in the rear movable louver 4, thereby 15 rotates to the left and right about the rotation shaft 16 as a fulcrum. At this time, the turning force is transmitted to the other vertical fins 15 via the eccentric shaft 17 and the link bar 18, and each vertical fin 15 rotates about the rotation shaft 16 as a fulcrum. The direction in the left-right direction changes with the rotation shaft 16 as an axis, and the air blowing direction is adjusted to the left or right.

  On the other hand, when adjusting the air blowing direction up or down, the operation knob 5 of the front movable louver 3 is turned up or down for adjustment. When the operation knob 5 is held and rotated downward, as shown in FIG. 5, the horizontal fin 13 to which the operation knob 5 is attached rotates downward about the rotation shaft 14, and the horizontal fin 13 The vertical direction changes obliquely downward with the rotation shaft 14 as an axis.

  At this time, in synchronization with the rotation of the horizontal fins 13, the barrel 10 is rotated downward via the linkage rotation mechanism 20, and the direction of the barrel 10 is directed obliquely downward. As a result, the upper and lower longitudinal frame portions 11b of the barrel 10 are inclined so as to face obliquely downward as shown in FIG. 5, and receive the wind passing near the upper wall or lower wall of the ventilation path 2a. It will be in the state of guiding below.

  Therefore, the air flow in the ventilation path 2a is prevented from flowing in a straight line through the gap between the fin and the upper wall of the front movable louver or between the fin and the lower wall as in the prior art. The air flow is first bent along the direction of the barrel 10 (obliquely downward), then bent along the horizontal fins 13 of the front movable louver 3, directed obliquely downward, and blown out from the air outlet 1a. The

  On the other hand, when the operation knob 5 is rotated upward, as shown in FIG. 6, the horizontal fin 13 on which the operation knob 5 is mounted rotates upward about the rotation shaft 14, and the horizontal fin 13 is moved up and down. The direction of the direction changes obliquely upward with the rotation shaft 14 as an axis, and in synchronization with the movement of the lateral fin 13, the barrel 10 is rotated upward via the linkage rotation mechanism 20, and the direction of the barrel 10 is changed. It changes diagonally upward. As a result, as shown in FIG. 6, the upper and lower longitudinal frame portions 11b of the barrel 10 are inclined so as to face obliquely upward, and the wind passing near the upper wall or lower wall of the ventilation path 2a is obliquely upward. It will be in the state to guide.

  Therefore, the air flow in the ventilation path 2a is prevented from flowing in a straight line through the gap between the horizontal fin 13 and the upper wall or between the horizontal fin 13 and the lower wall, as described above. The air flow is first bent along the direction of the barrel 10 (obliquely upward), then bent along the lateral fins 13 of the front movable louver 3, directed obliquely upward, and blown out from the air outlet 1a. The

  As described above, when the horizontal fin 13 is adjusted to be inclined upward or diagonally downward, the barrel 10 and the horizontal fin 13 located behind (in the rear) cooperate to guide the air flow in the same direction. Therefore, even if the register has a long and narrow air outlet 1a in the longitudinal direction and a small number of lateral fins 13 are provided in the front movable louver 3 in parallel with the longitudinal direction, the width of the lateral fins 13 of the front movable louver 3 is increased. The wind directivity can be effectively improved without widening.

  That is, in the case of a register having an elongated air outlet 1a, the number of horizontal fins is inevitably small, and the width of the lateral fins in the short direction is increased in order to effectively change the direction of the wind with the small number of horizontal fins. When the need arises, the width of the horizontal fin 13 can be kept small by rotating the barrel 10 together with the horizontal fin 13 as described above, and the barrel 10 and the horizontal fin 13 cooperate to guide the air flow. It is possible to suppress noise due to air pressure loss and air flow.

  In the above embodiment, only one horizontal fin 13 is provided on the front movable louver 3. However, two to three horizontal fins are arranged in parallel in the horizontal direction, and the longitudinal direction of the elongated air outlet 1a. 2 to 3 horizontal fins can be juxtaposed along the inside.

  Moreover, in the said embodiment, although the horizontal fin 13 was provided in the front movable louver 3 and the vertical fin 15 was provided in the rear movable louver 4 about the register | resistor with the horizontally long air blower outlet 1a, they were rotated 90 degree | times. It is also possible to provide a vertically long air outlet, to provide one to three vertical fins on the front movable louver, and to arrange a plurality of horizontal fins on the rear movable louver.

  In the above embodiment, the rectangular air outlet 1a is used. However, the air outlet is not necessarily rectangular, and may be an air outlet having an oblong shape such as an ellipse.
