Description

  The present invention relates to an operation knob used to operate a movable louver in an air blowing adjustment register used for an air outlet of an air conditioner such as an automobile, and more particularly to an elongated air that is long in the longitudinal direction and short in the lateral direction. The present invention relates to an operation knob suitable for a thin register having an air outlet.

  As a register for adjusting the air blowing of the air conditioner, the laterally movable louver and the longitudinally movable louver are arranged in the bezel or retainer forming the ventilation path so as to be perpendicular to each other, and air is supplied from the air outlet provided in the bezel. A resistor that adjusts the air blowing direction by changing the angle of each fin of the horizontally movable louver and the vertically movable louver is used for air conditioning of automobiles.

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

JP 2002-103954 A

  In this type of thin register, about 1 to 3 front movable fins are arranged along the longitudinal direction inside a slender air outlet, and a number of rear movable fins are arranged upstream of the front movable fins. These are pivotally supported in the short direction perpendicular to the front movable fin, and are arranged in parallel in the longitudinal direction at intervals.

  However, if the air outlet of the register has a long and narrow shape that is long in the longitudinal direction and short in the lateral direction, and the length in the lateral direction is very short and extremely thin, the air outlet is directed toward the air outlet. The air flow to be blown is compressed in the short direction and a contracted flow is likely to occur, and in particular, the phenomenon that the directivity of the wind when the rear movable fin is shaken in the longitudinal direction is likely to deteriorate due to the contracted flow occurs. It was.

  Therefore, in order to improve the deterioration of directivity caused by the contraction flow as described above in the thin register, the front movable fin is arranged in parallel to the short direction of the air outlet and the rear movable fin is parallel to the longitudinal direction. A thin register has been developed to improve the directivity of the wind when the rear movable fin is shaken in the short direction.

  This type of register has both sides along the longitudinal direction so that the ridges with an inclined surface on the upstream side just inside the air outlet and the air flow in the ventilation path bend toward the center of the air outlet. And a front movable louver having a plurality of front fins immediately upstream of the chevron ridges is rotatable in a longitudinal direction through a support shaft along the short direction of the air outlet. A rear movable louver having a single rear fin that changes the wind direction in the short direction in a ventilation path upstream of the front movable louver and is arranged in parallel at intervals, is rotated via a support shaft along the longitudinal direction. It is pivotally supported.

  In such a thin register, when the wind direction is changed to the short direction of the air outlet, the rear fin of the rear movable louver is rotated in the short direction, and the air flow contracted by the rear fin is applied to the chevron. By this, it bends in the direction opposite to the short direction bending by the rear fin, and operates to change the wind direction to the short direction. When the wind direction is changed in the longitudinal direction, the plurality of front fins of the front movable louver are rotated in the longitudinal direction so as to change the wind direction in the longitudinal direction.

  By the way, in the case of the conventional register as described in Patent Document 1, the operation mechanism for changing the wind direction is fitted on the front fin of the front movable louver so that the operation knob is slidable along the longitudinal direction. When the engagement portion is provided on the back side of the operation knob, the engagement portion engages with the rear fin arranged in parallel in the short direction of the rear movable louver, and when the operation knob is slid in the longitudinal direction, The rear fin is rotated to change the wind direction in the longitudinal direction of the air outlet.

  However, in the case of the thin register as described above, that is, it has an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and a plurality of front movable fins are arranged in parallel to the lateral direction, and parallel to the longitudinal direction. In the thin register with the rear movable fin arranged on the front, when the conventional operation knob is used, the front fin of the front movable louver is very short, so the operation knob is slidably fitted on the front fin. Even if the operation knob is slid on the front fin, it is difficult to effectively rotate the rear fin of the rear movable louver. Therefore, there has been a demand for a small operation knob that can be easily operated on the front surface of the thin register as described above and can change the wind direction appropriately.

  The present invention has been made in view of the above points, and is a thin type including a front movable louver in which a plurality of front fins are arranged in the short direction and a back movable louver in which a back fin is arranged in the longitudinal direction on the upstream side.

Opening and closing in the road 3 is performed.

  The register having the above-described configuration can be used by attaching the bezel 2 to the air blower outlet of an air conditioner provided in an instrument panel or the like of an automobile, for example, depending on the design of the instrument panel or the like. As shown in FIG. 14, a separate design cover 10 can be fitted on the outside of the bezel 2 of the register, and the register with the design cover 10 attached can be attached to an instrument panel or the like in the vehicle interior.

  When changing the register blowing direction upward, as shown in FIG. 12, the fan-shaped gripping portion 46 of the operation knob 4 is operated upward, and the front portion of the operation knob main body 42 is moved upward with the knob support shaft 43 as an axis. Turn to. Thereby, the bifurcated engagement portion 45 at the rear of the operation knob main body 42 is rotated downward, and the downstream end portion of the back fin 81 of the back movable louver 8 is rotated so as to be directed obliquely downward.

  Thus, the air flow flowing through the ventilation path 3 is bent and contracted obliquely downward in the short direction by the back fins 81 of the back movable louver 8 as shown in FIG. 5 passes between the front fins 51 and changes the air direction in the longitudinal direction (left and right direction) according to the direction of the front movable louver 5, and in this state, the air flow of the ventilation path 3 starts from the lower wall surface to the lower side. It hits the inclined surface 7a of the side chevron ridge 7 and is bent upward, and is blown obliquely upward from the air outlet 2a.

  On the other hand, when changing the blowing direction downward, as shown in FIG. 11, the fan-shaped gripping portion 46 of the operation knob 4 is operated downward, and the front portion of the operation knob main body 42 is moved downward with the knob support shaft 43 as an axis. Turn to the side. As a result, the bifurcated engagement portion 45 at the rear of the operation knob main body 42 is turned upward, and the back fin 81 of the back movable louver 8 is turned so that the downstream end thereof is directed obliquely upward. To do.

  Accordingly, the air flow flowing through the ventilation path 3 is bent and contracted obliquely upward in the short direction by the back fins 81 of the back movable louver 8 as shown in FIG. 5 passes between the front fins 51, changes the wind direction in the longitudinal direction (left-right direction) according to the direction of the front movable louver 5, and in that state, the air flow flowing through the ventilation path 3 from the upper wall surface, It hits the inclined surface 6a of the upper chevron 6 and is bent downward, and is blown obliquely downward from the air outlet 2a.

  On the other hand, when the air blowing direction is swung left and right, as shown in FIG. 13, the fan-shaped grip 46 on the front surface of the front movable louver 5 is held and rotated left or right. As a result, the operation knob case 41 rotates to the left or right with the operation knob main body 42 and the upper and lower case support shafts 44 as the axis, and the movement of the operation knob case 41 is entirely transmitted through the link member 55 to the front movable louver 5. As shown in FIG. 13, all the front fins 51 of the front movable louver 5 are rotated so as to face left or right, and the wind direction is changed to left or right.

  In this way, in the current-transforming portion that changes the wind direction in the short direction (vertical direction), the back movable louver 8 portion becomes a contraction portion, and the chevron ridges 6 and 7 portions become deflection portions, thereby shortening the wind direction. The current-transforming operation when bending obliquely downward or upward in the hand direction is divided into contraction by the rear movable louver 8 and deflection by the chevron ridges 6 and 7. For this reason, when the air flow passes from the front movable louver 5 through the chevron ridges 6 and 7, the contracted flow (compressed air flow) is reduced, whereby the front movable louver 5 is rotated to move the wind direction. The phenomenon that the wind direction is returned by the contracted flow is reduced when the is changed to the left and right longitudinal direction.

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

  In the above embodiment, in the case body 1 having a horizontally long air outlet 2a and having a vertically short shape, the front fins 51 of the front movable louver 5 are arranged in parallel in the vertical direction as shown in FIG. The back fins 81 of the back movable louver 8 are arranged in parallel with the horizontal horizontal direction, but they are rotated 90 degrees, the case body is vertically elongated, and a vertically long slit-like air outlet is provided. Provided on the case body, the front fin of the front movable louver is arranged in parallel with the horizontal horizontal direction which is the short direction of the air outlet, and the rear fin of the rear movable louver is parallel to the longitudinal direction which is the longitudinal direction of the air outlet It can also be provided. In this case, the ridges on the inner side of the air outlet are provided in the longitudinal direction parallel to the longitudinal direction of the air outlet.
