Description

  The present invention relates to an air blowing adjustment register used for an air-conditioning outlet of an automobile or the like, and more particularly to a register having a structure in which the front surface of an air outlet is visually non-transparent.

  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, the laterally movable louver A register that adjusts the air blowing direction by changing the angle of each fin of the longitudinally movable louver is provided on an instrument panel or the like as an air outlet of an automobile air conditioner.

  In recent years, interior design in the vicinity of instrument panels in automobile interiors has a tendency to be based on the concept of a simple, modularized image with a sense of unity overall. A non-transparent air-conditioning register is proposed in Patent Document 1 below.

This register covers the front surface of the air outlet with a lattice, and the lattice makes the internal mechanism such as the interference member for adjusting the wind direction arranged in the interior a non-transparent structure that is difficult to visually see. A lattice having a structure in which a large number of polygonal holes are arranged inside a substantially rectangular annular rim is attached so as to cover the entire front surface of the air outlet of the register.
JP 7-504632 A

  However, although this conventional register makes the wind direction adjustment mechanism of the register difficult to see visually by the lattice, a lattice having an annular rim at the peripheral edge is fitted over the entire air outlet. Therefore, the pressure loss at the time of the ventilation by a grating | lattice is large, and when the wind direction was adjusted by moving an internal wind direction adjustment mechanism with an operation knob, there existed a subject to which the wind speed feeling and spot feeling of a wind fell remarkably by a grating | lattice.

  Furthermore, the wind direction adjusting mechanism of this register is structured to change the wind direction by tilting the rectangular frame-shaped interference member left and right or up and down with the operation knob, so that the wind direction can be obtained only by tilting the rectangular frame-shaped interference member. As a result, the wind speed feeling and the spot feeling at the time of blowing were impaired.

  On the other hand, in order to make the interior design of the interior of the vehicle uniform, or to make the front of the air outlet of the register visually non-transparent, the shape of the air outlet is formed into a slit shape that is elongated vertically or horizontally. However, in the conventional register described above, when the shape of the air outlet is a long and narrow slit in the longitudinal direction, the rectangular frame-shaped interference member is tilted so that the air direction is changed in the short direction of the outlet. Even if the adjustment is made, the wind direction adjustment function of the interference member is low, and there is a problem that the wind speed feeling and the spot feeling during the wind direction adjustment are poor.

  The present invention has been made in view of the above points, and provides a register capable of visually making the front surface of an air outlet visually non-transparent and improving a wind speed feeling and a spot feeling at the time of wind direction adjustment. For the purpose.

In order to achieve the above object, the register of the present invention provides:
In a register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and a barrel pivotally supported around the longitudinal axis inside the air outlet,
A movable louver is provided in the barrel such that a plurality of fins are pivotally supported around an axis orthogonal to the rotation axis of the barrel.
An operation knob is provided to rotate the barrel about the rotation axis and adjust the wind direction by rotating the fins of the movable louver about the axis;
A lattice portion is provided so as to substantially cover the front of the air outlet,
A slit opening is provided on both sides of the lattice portion in the longitudinal direction of the air outlet.

  According to the register of the present invention, the lattice portion is provided so as to cover the front of the air outlet, and the interior is concealed. Therefore, the inside of the register is visually made non-transparent, and the design of the register front is improved. When the wind direction is adjusted by rotating the barrel, it is possible to effectively blow air from the slit openings on both sides of the lattice portion, thereby improving the wind speed feeling and the spot feeling at the time of adjusting the wind direction.

  Here, in the register, a front surface of the register is integrally formed by a front plate of a bezel that forms a front portion of the register, the air outlet is formed in a central portion of the front plate, and the lattice portion is It extends from the edge of the face plate and substantially covers the air outlet and is formed by providing slit openings on both sides of the lattice portion, and an opening for the knob is provided at the edge of the front plate. It is preferable to arrange the operation knob in the opening.

  According to the present invention, the front surface of the register is formed integrally with the front plate of the bezel, and the lattice portion is provided so as to cover the air outlet of the front plate. .

  Further, in the register, the operation knob is configured such that a knob body is slidably supported on a knob shaft horizontally supported on a lower side of the front plate of the bezel, and the knob body includes a knob. A holding portion is provided so as to be movable together with the knob body, and a barrel link mechanism is provided that transmits the movement of the knob body in the axial direction to the turning shaft of the barrel via the knob holding portion, and rotates. It is preferable to provide a movable louver link mechanism that transmits the rotation of the knob body to each fin of the movable louver to tilt the knob body.

  According to the present invention, the angle of the barrel direction and the angle of the fins of the movable louver can be adjusted by a simple mechanism and operation of one knob body, and the wind direction can be easily changed vertically and horizontally.

  According to the register of the present invention, the front surface of the air outlet can be made visually non-transparent to improve the feeling of wind speed and the feeling of spot when adjusting the wind direction.

It is a front view of the register | resistor which shows one Embodiment of this invention. It is a left view of the register. It is a disassembled perspective view of the register. It is IV-IV sectional drawing of FIG. It is VV sectional drawing of FIG. It is IV-IV sectional drawing of the state which turned the horizontal fin of the movable louver downward. It is VV sectional drawing of the state which turned the direction of the barrel to the left.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 7, the register of the present embodiment is such that the front surface of the air outlet 10 formed in the bezel 1 is substantially covered with the lattice portion 13, so that the inside thereof is visually non-transparent. It has a structure. The front plate 11 of the bezel 1 is formed by bending a substantially rectangular plate up and down, and an air outlet 10 is formed there in a vertically long rectangular shape. The air blower outlet 10 is formed so that the lattice part 13 covers the blower outlet at the center, and longitudinally long slit openings 12 are formed on both sides of the lattice part 13 in the longitudinal direction (vertical direction) of the air blower outlet 10. Formed along.

  That is, the air outlet 10 includes a lattice portion 13 that covers the center portion, and slit openings 12 and 12 that are disposed on both sides of the lattice portion 13, and the lattice portion 13 has upper and lower edges of the front plate 11. It is integrally formed so as to extend from the part. The lattice of the lattice portion 13 is formed by arranging a large number of hexagonal holes vertically and horizontally, and the lattice portion 13 is formed by bending in the vertical direction in the same manner as the front plate 11. Here, the lattice portion 13 is formed in a honeycomb shape by arranging a large number of hexagonal holes vertically and horizontally, but can also be formed by arranging a large number of circular holes and square holes vertically and horizontally in addition to the hexagonal holes.

  In the embodiment shown in FIG. 1, the width ratio between the lattice portion 13 and the slit openings 12, 12, that is, the ratio of a: b: a in FIG. 1 is 7: 30: 7, and the air outlet 10 The ratio of the width of the lattice portion 13 and the ratio of the width of the slit opening 12 when the width of the slit is set to 100 (%) are 16 (%): 68 (%): 16 (%).

  The relationship between the width b of the lattice portion 13 and the width a of the slit opening 12 is such that as the width of the lattice portion 13 is narrower and the width of the slit opening 12 is wider, the inside of the register becomes easier to visually see and the design is degraded. On the other hand, the flow of the wind when the direction of the wind is swung left and right is improved, and conversely, as the width of the lattice portion 13 is wider and the width of the slit opening portion 12 is narrower, the inside of the register becomes less visible visually. As a result, the design is improved, but the draft of the wind is worsened when the direction of the wind is swung from side to side.

  In consideration of this point, in order to make the inside of the register difficult to see visually, to improve the design, and to improve the draft of the wind when the direction of the wind is swung to the left and right, The width ratio between the slit openings 12 and 12 is effectively in the range of 10 (%): 80 (%): 10 (%) to 22 (%): 56 (%): 22 (%). Yes, desirably, it is in the range of 13 (%): 74 (%): 13 (%) to 19 (%): 62 (%): 19 (%).

  The bezel 1 having the front plate 11 in which the lattice portion 13 and the slit openings 12 and 12 are formed in the air outlet 10 is integrally formed with, for example, ABS resin. By forming the lattice portion 13 integrally when the bezel 1 is formed, it is possible to reduce the number of parts and the number of assembling steps as compared with the case where a separate lattice member is fitted into the air outlet.

  As shown in FIG. 1, a knob opening 14 is formed in the lower part of the front plate 11, and the knob body 6 of the operation knob 5 is disposed so as to be exposed (projected) forward from the opening 14. The left and right directions of the barrel 3 are adjusted by sliding the operation knob 5 to the left and right, and the horizontal fins 31 of the movable louver 4 are adjusted up and down by rotating the operation knob 5.

  A rectangular fitting portion for connecting to the retainer 2 is provided on the inner side (rear side) of the bezel 1, and two pairs of locking portions 18 are arranged at the rear side as shown in FIG. 3 on both sides of the fitting portion. Projected toward. On the other hand, a duct-like retainer 2 is connected to the rear portion of the bezel 1 by fitting the locking portions 18 to two pairs of locking receiving portions 21 provided on the side walls thereof.

  As shown in FIG. 3, the retainer 2 is formed in a substantially square duct shape, and has an air passage 9 formed therein, and is open to the front and rear. Bearing portions 22 and 23 for supporting the upper and lower rotary shafts 3a and 3b of the barrel 3 are formed on the upper and lower portions of the front edge portion of the retainer 2, and the barrel 3 is interposed between the bearing portions 22 and 23. The upper and lower rotary shafts 3a and 3b are inserted into and supported by the bearing portions 22 and 23 so as to be supported. Further, the bearing portions 22 and 23 are provided with locking claws or locking recesses, and when the bezel 1 is fitted to the front portion of the retainer 2, the bearing portions 22 and 23 are fitted to the rear portion of the bezel 1. It has a structure. Thus, the bezel 1 having the air outlet 10 formed in the front is fitted to the front portion of the retainer 2 so as to match the air outlet 10 with the opening of the air passage 9.

  As shown in FIG. 3, the barrel 3 has a vertically long opening space, is formed to open in the front and rear, is attached to the front portion of the retainer 2, and the upper and lower rotary shafts 3 a and 3 b are used as axes. By turning left and right, the direction of the wind blown from the air outlet 10 is changed to the left or right. A crank 3 c is connected to the rotating shaft 3 b at the lower part of the barrel 3, and a biased shaft 3 d of the crank 3 c is engaged with a forked engagement portion 15 a of the knob holding portion 15 in the knob body 6 of the operation knob 5.

  The knob holding part 15 is formed with an opening 15b that exposes or protrudes the knob body 6 forward, and a bearing part 15c that holds the knob shaft 16 that supports the knob body 6 is provided inside the knob holding part 15. In a state where the knob shaft 16 is held by the bearing portion 15c, the knob body 6 is attached so that a part of the knob body 6 is exposed from the opening 15b. Accordingly, when the knob body 6 of the operation knob 5 is moved to the right or left on the knob shaft 16, the bifurcated engagement portion 15a of the knob holding portion 15 is similarly moved to the right or left, and the crank 3c is moved to the bias shaft 3d. The rotating shaft 3b in the lower part is rotated by receiving the rotational force through the shaft 3 and the barrel 3 is rotated right and left about the upper and lower rotating shafts 3a and 3b.

  As shown in FIGS. 2 and 3, the knob body 6 of the operation knob 5 is slidable in the axial direction on the knob shaft 16 supported horizontally by the knob bearing portions 25, 25 provided at the lower portion of the retainer 2. Attached to. The knob shaft 16 has a cross section formed as an axis of a non-circular cross section, and a deformed hole having a shape corresponding to the cross section of the knob body 6 is formed at the axial center position of the knob main body 6. The knob body 6 can be slid in the direction, and the turning force can be transmitted to the knob shaft 16 when the knob body 6 is rotated. An operation load applying material 6a such as a rubber-like elastic body is fitted into the deformed hole of the knob body 6 so that an appropriate operation load is applied when the knob body 6 is slid on the knob shaft 16. I have to.

  The knob shaft 16 is rotatably supported by knob bearings 25, 25 provided at the lower portion of the retainer 2, and a crank 17 is provided at the end of the knob shaft 16, and the crank 17 is connected via a link 38. It is linked to a fin rotation shaft 35 that rotates the horizontal fin 31 of the movable louver 4.

  The movable louver 4 is configured, for example, by horizontally arranging four horizontal fins 31 in the barrel 3 in the horizontal state, and each horizontal fin 31 has both sides in the barrel 3 as shown in FIGS. The fin shaft 32 is inserted into a shaft hole provided in the barrel side wall, and is supported so as to be rotatable up and down in the barrel 3. As shown in FIGS. 4 and 5, biased shafts 31a are provided on both sides of the fins 32 on both sides of the rear portion of the lateral fins 31 so as to protrude from both sides, and a pair of links is formed by connecting the biased shafts 31a on both sides. Bars 33 and 33 are attached, and the pair of link bars 33 and 33 are connected by an arcuate link 34.

  On the other hand, the fin rotation shaft 35 for rotating the horizontal fin 31 of the movable louver 4 is horizontally supported by horizontal bearing portions 24 and 24 provided on the side wall of the retainer 2 as shown in FIGS. A bifurcated engaging portion 36 is provided at an intermediate portion of the fin rotation shaft 35, and an arcuate link 34 connected to the lateral fin 31 engages with the bifurcated engaging portion 36. As a result, when the fin rotation shaft 35 rotates, the bifurcated engagement portion 36 rotates up and down, and the pair of link bars 33 move up and down via the arc-shaped links 34, and the link bars 33 move up and down. Thus, the four horizontal fins 31 of the movable louver 4 are rotated up and down around the fin shaft 32.

  Since the fin rotation shaft 35 is connected to the link 38 via the crank 37 and the link 38 is connected to the knob shaft 16 via the crank 17, the knob shaft 16 is rotated by operating the operation knob 5. The fin rotation shaft 35 is rotated via the link 38, and the bifurcated engagement portion 36 pivotally attached to the fin rotation shaft 35 is rotated. As a result, the arc-shaped link 34 and a pair of link bars are rotated. As the link bar 33 moves up and down, the horizontal fins 31 of the movable louver 4 in the barrel 3 rotate up and down around the fin shaft 32.

  Therefore, the movable louver link mechanism for rotating the horizontal fins 31 of the movable louver 4 by rotating the operation knob 5 includes the knob shaft 16, the crank 17, the link 38, the crank 37, the bifurcated engagement portion 36, and the fin rotation. The shaft 35 is composed of an arc-shaped link 34 and a pair of link bars 33. The barrel link mechanism for rotating the barrel 3 to the left and right by the sliding operation of the operation knob 5 includes a knob shaft 16, a knob holding portion 15, a bifurcated engagement portion 15a, a biased shaft 3d, a crank 3c, and a rotating shaft 3b. A structure in which the horizontal fin 31 of the movable louver 4 is rotated up and down by rotating the operation knob 5 and the direction of the barrel 3 is changed to right or left by sliding operation of the operation knob 5 in the horizontal direction. It has become.

  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).

  As shown in FIG. 1, the front surface of the register is provided with a lattice portion 13 in the center of the front surface of the air outlet 10 and the lattice portion 13 conceals the inside of the register. The design of the front side of the register is improved.

  During blowing of the register, air sent from a ventilation duct (not shown) passes through the barrel 3 from the ventilation path 9 in the retainer 2 and is blown out through the lattice portion 13 and the slit opening portion 12 of the air outlet 10.

  As shown in FIGS. 4 and 5, in the state in which the direction of the barrel 3 is the front side and parallel to the blowing direction of the ventilation path 9, the blown air flow passes straight through the barrel 3 as it is, and the air outlet 10 lattice parts 13 and slit openings 12, 12 are blown forward. In the state where each horizontal fin 31 of the movable louver 4 faces slightly upward as shown in FIG. 4, the air flow is bent upward when passing around the horizontal fin 31, and blown obliquely upward from the air outlet 10. The

  In this state, when the knob body 6 of the operation knob 5 is held and rotated, for example, downward, the knob shaft 16 and the crank 17 are rotated as shown in FIG. The moving shaft 35 rotates. At this time, the bifurcated engagement portion 36 pivotally attached to the fin rotation shaft 35 is rotated upward, whereby the arc-shaped link 34 and the link bar 33 are raised, and each of the movable louvers 4 is moved as shown in FIG. The horizontal fins 31 are rotated clockwise around the fin shafts 32, and each horizontal fin 31 faces obliquely downward. For this reason, the airflow which passes the ventilation path 9 flows along each horizontal fin 31, and is ventilated diagonally downward from the lattice part 13 and the slit opening parts 12 and 12 of the air blower outlet 10. FIG.

  On the other hand, when adjusting the air blowing direction to the left and right, the knob body 6 of the operation knob 5 is adjusted by moving it to the left or right on the knob shaft 16. For example, when the air blowing direction is directed to the left, when the knob main body 6 of the operation knob 5 is held and moved to the left, the knob holding portion 15 slides to the left on the knob shaft 16 together with the knob main body 6. 15 is moved to the left side, and the rotating shaft 3b at the bottom of the barrel 3 rotates in the clockwise direction in FIG. 7 via the biasing shaft 3d and the crank 3c, whereby the barrel 3 is moved to the movable louver 4. At the same time, it pivots about the upper and lower pivot shafts 3a and 3b, and the direction of the barrel 3 is directed leftward. At this time, as shown in FIG. 7, since there is a slit opening 12 on the left side of the air outlet 10 to which the barrel 3 is directed, the air flow bent to the left by the barrel 3 through the ventilation path 9 is mainly Then, the air passes through the left slit opening 12 smoothly and is blown.

  Similarly, when the knob body 6 of the operation knob 5 is held and moved to the right, the rotating shaft 3b below the barrel 3 via the knob holding portion 15, the bifurcated engaging portion 15a, the biasing shaft 3d, and the crank 3c. Rotates counterclockwise, the barrel 3 rotates about the upper and lower rotation shafts 3a and 3b together with the movable louver 4, and the barrel 3 is directed rightward. At this time, similarly to the above, since there is a slit opening 12 on the right side of the air outlet 10 to which the barrel 3 is directed, the air flow bent to the right by the barrel 3 through the ventilation path 9 is the right slit. Sufficient wind speed and a feeling of spot are obtained for the passenger who has passed through the opening 12 smoothly and is blown and received wind.

  As described above, when the wind direction is adjusted by rotating the barrel 3 to the left and right, the air is effectively blown from the slit openings 12 and 12 on both sides of the lattice portion 13 to improve the wind speed feeling and the spot feeling at the time of the wind direction adjustment. Can be made. In addition, since the lattice portion 13 covers the air outlet on the front of the register to make the inside of the register visually impermeable, the design and appearance of the front of the register are improved, and slit openings 12 and 12 are provided on both sides. Since it is provided, it is possible to improve the escape of the wind particularly when the wind direction is adjusted to the left and right, and to suppress the pressure loss during the blowing.

  In the above embodiment, the lattice portion 13 is provided in the central longitudinal direction of the vertically long air outlet 10 and the slit openings 12 are disposed on both sides thereof. However, the slit openings are provided at the upper and lower portions of the lattice portion. You can also.
