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, and a movable louver is provided along the longitudinal direction inside the air outlet. Related to the register.

  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 And the register which changes the angle of each fin which orthogonally crosses a longitudinally movable louver and adjusts the blowing direction of air is provided in the instrument panel etc. as a blower outlet of the air conditioner of a car.

In recent years, the design in the vicinity of an instrument panel in an automobile interior is based on the concept of a simple and uncomfortable image as a whole, and because of the increased display layout, the space for air conditioning registers has been reduced. The outlet shape is not conspicuous in design and tends to be designed as a thin slit shape. Such a slit-type register has an elongated shape in which the air outlet is inevitably long in the longitudinal direction and short in the lateral direction, and usually 1 or 2 sheets are provided in the front movable louver of the air outlet. A certain degree of fin is provided along the longitudinal direction (see, for example, Patent Document 1 below).
JP 2007-331417 A

  The register having this elongated air outlet has an elongated shape that is long in the longitudinal direction and short in the lateral direction, so that the number of fins of the front movable louver that is long in the longitudinal direction is inevitably 1, 2. The number of fins is smaller than the number of fins of the front movable louver of a normal register.

  However, a register having such an elongated air outlet has a short direction of the air outlet when the number of fins of the front movable louver along the longitudinal direction is as small as, for example, about one or two. 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 the directionality of the wind during blowing deteriorates.

  For this reason, the front and rear width of the fins of the front movable louver is usually increased to improve the directivity. However, when the front and rear width of the fins of the front movable louver is increased, for example, as shown in FIG. When the front movable louver 50 has three fins 51, 52, 53, when the direction of the fins 51, 52, 53 is adjusted, the rear end of the fin 53 positioned outside the whole fin direction is the ventilation path 54. Interfering with the wall surface H.

  In order to avoid such interference with the wall surface H of the fin 53, the front-rear width “a” of the fin 53 is shortened, the width of the ventilation path 54 in the vertical direction (short direction) is increased, or the wall H is recessed. However, for that purpose, even when manufacturing a slit type register having an elongated air outlet, the width of the air passage and the air outlet in the short direction must be widened. was there.

  The present invention has been made in view of the above points, and even when the shape of the air outlet is an elongated shape and the number of fins is small, the directivity at the time of wind direction adjustment can be improved. The purpose is to provide a register.

In order to achieve the above object, a register according to claim 1 of the present invention includes a movable louver in which a plurality of fins are rotatably arranged in a ventilation path and the direction of the fins is changed to adjust the wind direction. In the register,
Fins of the movable louver arranged adjacent to the wall surface of the ventilation path are formed as expansion and contraction fins. The expansion and contraction fins are parallel to the plane and open on the back surface, and are provided with body fins and slits. A sliding fin that is slidably inserted into the groove, and both end portions of the main body fin are pivotally supported on the wall surface of the air passage by a pivot, and guide shafts are provided on both end portions of the sliding fin. The guide shaft is engaged with a guide groove formed on the wall surface of the ventilation path, and the movable louver is oriented from the front so that the rear end of the expansion and contraction fin faces the center side of the ventilation path. The sliding fin protrudes backward from the inside of the main body fin and moves when it is changed vertically or horizontally.

  According to the register of the present invention, for example, when three fins are arranged side by side in the movable louver, the sliding direction is such that the direction of the movable louver is parallel to the ventilation direction of the ventilation path and is directed to the front of the air outlet. The moving fin is accommodated in the slit groove of the main body fin, and there is no or little protrusion to the rear. However, when the direction of the movable louver is swung up and down or left and right from the front, the expansion and contraction fin that directs the rear end of the fin adjacent to the wall surface toward the center of the air passage slides the guide shaft of the sliding fin in the guide groove. Since the sliding fin moves so that it protrudes backward from the main body fin, this increases the front-back width of the expansion and contraction fins and improves the directivity of the wind when the direction of the movable louver is adjusted up and down or left and right Can be made.

  In addition, since only the expansion and contraction fins that direct the rear end of the fin toward the center of the air passage project the sliding fin, the expansion and contraction fin that directs the rear end of the fin toward the wall surface of the air passage and the sliding fin is the main body fin. It is housed inside and its front-rear width is short. For this reason, the rear end of the expansion and contraction fin does not interfere with the wall surface of the ventilation path, and even if it is a slit type register in which the width in the short direction of the ventilation path is narrowed and the air outlet is elongated, The fin can be rotated without interfering with the wall surface in the air passage. For this reason, in order to avoid the interference of fins, it is not necessary to provide a notch recess in the wall surface of the ventilation path or to extend the shape of the ventilation path in the short direction, and the external shape of the register can be reduced in size.

  Here, in the register, the movable louver is composed of three fins in which two expansion fins are arranged on both sides of the central fin, and only the two expansion fins open a slit groove parallel to the plane on the back surface. The main body fin provided in this manner and a sliding fin that is slidably inserted into the slit groove, and the pivots of the three fins are connected to each other via a crank and a link bar. Can do.

  Further, in the register, the movable louver is a front movable louver, a rear movable louver is disposed behind the front movable louver, and the rear movable louver rotates a plurality of fins orthogonal to the fins of the front movable louver. They can be arranged side by side as possible.

  Further, the register according to claim 4 of the present invention has a long and narrow air outlet that is long in the longitudinal direction and short in the lateral direction, and is movable in front of the air outlet and includes a single fin along the longitudinal direction. In a register in which a louver is disposed and a rear movable louver is disposed behind the front movable louver, the fins of the front movable louver are formed as expansion / contraction fins whose front and rear widths expand and contract, and the expansion / contraction fins are parallel to a plane. The main body fin is provided with a slit fin provided on the back surface thereof and a sliding fin that is slidably inserted into the slit groove. Both side ends of the main body fin are pivotally connected to the wall surface of the ventilation path. The guide shaft protrudes from both side end portions of the sliding fin, and the guide shaft is engaged with a guide groove formed on the wall surface of the ventilation path. When changed to the left-right direction, Emissions is thus being moved projecting rearwardly from the body fins.

  According to the register of the present invention, in a state in which one expansion / contraction fin of the front movable louver faces the front of the air outlet, the sliding fin is accommodated in the slit groove of the main body fin and is not projected backward. Or, although small, when the direction of the expansion and contraction fins is swung up and down or left and right from the front, the guide shaft of the sliding fin slides in the guide groove and moves so that the sliding fin protrudes rearward from the main body fin. Thereby, the front-back width | variety of an expansion-contraction fin increases, and the directivity of a wind can be improved.

  In addition, when the direction of the expansion / contraction fins of the front movable louver is parallel to the air flow direction of the ventilation path, the sliding fins are housed in the main body fins, and the front / rear width of the expansion / contraction fins is shortened, allowing the position of the rear movable louver. As close as possible to the air outlet, it is possible to improve the directivity of the wind when the direction of the fins of the rear movable louver is adjusted vertically or horizontally.

  According to the register of the present invention, even when the shape of the air outlet is elongated and the number of fins is small, the directivity at the time of adjusting the wind direction can be improved. The length of the direction can be shortened to make the register compact.

It is a description longitudinal cross-sectional view of the conventional register | resistor.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 8 show the register of the first embodiment. In the figure, reference numeral 1 denotes a bezel having a rectangular horizontally long air outlet 10 formed in the front, and a retainer 2 is connected to the rear portion of the bezel 1. As shown in FIG. 1, the air outlet 10 is formed in a flat and elongated rectangle, and is formed in a horizontally long rectangle that is long in the longitudinal direction and short in the lateral direction.

  A fitting portion (not shown) for connecting to the retainer 2 is provided on the back side of the bezel 1, and the duct-like retainer 2 is fitted and connected to the fitting portion. A ventilation path 9 is formed in the bezel 1 and the retainer 2, and the front movable louver 3 and the rear movable louver 4 move back and forth in the ventilation path 9, and the respective horizontal fins (central horizontal fins 11) and vertical fins 21 are connected. They are arranged in an orthogonal form. As shown in FIG. 6, a bearing portion 1 b for the front movable louver 3 is attached to the left and right side walls of the ventilation path 9 of the bezel 1, and the central horizontal fin of the front movable louver 3 is attached to the shaft hole provided in the bearing portion 1 b. 11 pivot shafts 11a, pivot shafts 13a of main fins 13 of upper telescopic fins 12, and pivot shafts 16a of main fins 16 of lower telescopic fins 15 are rotatably supported.

  As shown in FIG. 6, the front movable louver 3 is configured by arranging three fins including a central lateral fin 11, an upper telescopic fin 12, and a lower telescopic fin 15 in parallel. An upper telescopic fin 12 is disposed in parallel above the central lateral fin 11, and a lower telescopic fin 15 is disposed in parallel below the central lateral fin 11. The central lateral fin 11 is a normal single fin, but the upper elastic fin 12 and the lower elastic fin 15 arranged adjacent to the wall surface of the air passage 9 are respectively the main body fins 13 and 16 and the main body fin. The sliding fins 14 and 17 slide with respect to 13 and 16, and the sliding fins 14 and 17 are slid so that the front-rear width can be expanded and contracted.

  As shown in FIGS. 6 and 7, the main fins 13 and 16 of the upper elastic fin 12 and the lower elastic fin 15 are respectively provided with slit grooves 13b and 16b from the back to the front, that is, parallel to the plane and on the back. A sliding fin 14 is slidably inserted in the slit groove 13b of the main fin 13 of the upper telescopic fin 12 so as to be slidable in the front-rear direction, and is slid into the slit groove 16b of the main fin 16 of the lower elastic fin 15. The moving fins 17 are inserted so as to be slidable in the front-rear direction. That is, the upper elastic fin 12 and the lower elastic fin 15 are arranged so that the sliding fin 14 and the sliding fin 17 enter and exit in the slit grooves 13b and 16b of the main body fins 13 and 16, so 15 has a structure in which the front-rear width is expanded and contracted.

  The upper telescopic fin 12 provided with the main body fin 13 and the sliding fin 14 supports the pivot shafts 13a and 13a projecting on both sides of the main body fin 13 on the bearing portion 1b on the side wall of the ventilation path 9, and rotates up and down. In particular, when the upper telescopic fin 12 is operated so that the rear end portion of the upper telescopic fin 12 is directed to the center in the ventilation path 9, from within the slit groove 13b of the main body fin 13 The sliding fin 14 protrudes rearward and moves, and the front-rear width of the upper telescopic fin 12 increases. On the other hand, when the upper telescopic fin 12 is operated downward so that the rear end portion of the upper telescopic fin 12 is directed to the side wall of the ventilation path 9, the front and rear width of the upper telescopic fin 12 is reduced.

  Similarly, the lower telescopic fin 15 provided with the main body fin 16 and the sliding fin 17 supports the pivots 16 a and 16 a protruding from both sides of the main body fin 16 on the bearing portion 1 b on the side wall of the ventilation path 9. In particular, when the lower telescopic fin 15 is operated so that the rear end portion of the lower telescopic fin 15 is directed to the center in the ventilation path 9, the slit groove of the main body fin 16 is provided. The sliding fin 17 protrudes backward from the inside of 16b and moves, and the front-rear width of the lower telescopic fin 15 is increased. On the other hand, when the lower telescopic fin 15 is operated upward so that the rear end portion of the lower telescopic fin 15 is directed to the side wall of the ventilation path 9, the front and rear width of the lower telescopic fin 15 is reduced. Yes.

  For this reason, the pivot shafts 13 a and 13 a at both end portions of the main fin 13 of the upper telescopic fin 12 are pivotally supported by the bearing portions 1 b on the side wall of the ventilation passage 9, and guide shafts 14 a are disposed at both end portions of the sliding fin 14. The guide shaft 14 a is projected and engaged with the upper guide grooves 2 a and 2 a formed on both side walls of the ventilation path 9. When the orientation of the upper telescopic fin 12 is adjusted upward from the front as shown in FIG. 7C and the rear end of the upper telescopic fin 12 faces the center of the ventilation path 9, the guide shafts 14a and 14a are As shown in FIG. 5, the upper guide grooves 2a and 2a are formed in an arc shape so that the guide grooves 2a and 2a slide in the guide grooves 14a and the slide fins 14 project rearward from the main body fins 13 and move. .

  Similarly, the pivot shafts 16 a and 16 a at both end portions of the main fin 16 of the lower expansion and contraction fin 15 are pivotally supported by the bearing portions 1 b on the side wall of the ventilation passage 9, and guide shafts 17 a and 16 b are mounted at both end portions of the sliding fin 17. The guide shafts 17 a and 17 a are engaged with lower guide grooves 2 b and 2 b formed on both side walls of the ventilation path 9. As shown in FIG. 7B, the shape of the lower guide grooves 2b, 2b is adjusted such that the direction of the lower elastic fin 15 is downward from the front, and the rear end of the lower elastic fin 15 faces the center of the ventilation path 9. As shown in FIG. 5, the guide shafts 17a and 17a slide in the lower guide grooves 2b and 2b, and the sliding fins 17 project rearward from the main body fins 16 and move. .

  3 and 6, the upper guide groove 2a and the lower guide groove 2b provided on both side walls of the air passage 9 are shown penetrating through the upper guide groove from the outside in consideration of airflow leakage. It is desirable to cover 2a and the lower guide groove 2b to prevent air leakage. Actually, the upper guide groove 2a and the lower guide groove 2b are closed from the outside by a cover or the like.

  Thus, when the upper telescopic fin 12 is operated downward or the lower telescopic fin 15 is operated upward so that the rear end of the upper telescopic fin 12 or the lower telescopic fin 15 is directed to the side wall side of the ventilation path 9, Since the front and rear widths of the upper telescopic fin 12 and the lower telescopic fin 15 are reduced, the rear end portions of the upper telescopic fin 12 and the lower telescopic fin 15 are less likely to interfere with the wall surface of the air passage 9, The ventilation path 9 can be reduced in height (vertical width) to make a flatter slit type register.

  On the other hand, the central lateral fin 11 is composed of a single fin, and the front-rear width in the front-rear direction is the front-rear direction of the upper telescopic fins 12 and the lower telescopic fins 15 with the sliding fins 14, 17 protruding rearward. It is formed approximately the same as the width. The pivots 11 a protrude from both side ends of the central lateral fin 11, and are supported by the bearing portion 1 b on the side wall of the ventilation path 9. Similarly, the pivot 13a of the main fin 13 of the upper telescopic fin 12 and the pivot 16a of the main fin 16 of the lower telescopic fin 15 are also supported by the bearing portion 1b on the side wall.

  When the direction of the front movable louver 3 is adjusted, as shown in FIGS. 4 and 6, the pivot 11a is arranged so that the central lateral fin 11, the upper telescopic fin 12, and the lower telescopic fin 15 rotate in the same direction. Cranks 18 are provided at the distal ends of the pivot shaft 13a and the pivot shaft 16a, and one link bar 19 is connected to the deflection shaft of the cranks 18, and the central lateral fin 11, the upper telescopic fin 12, and the lower telescopic fin 15 is structured to be interlocked when rotating. Although omitted in the drawings, it is preferable to provide an operation knob portion used for adjusting the direction of the fin of the front movable louver 3 up and down at the front portion of the central lateral fin 11.

  On the other hand, as shown in FIG. 7, the rear movable louver 4 is disposed in the ventilation path 9 at the rear (back) of the front movable louver 3. In the rear movable louver 4, a plurality of vertical fins 21 are vertically arranged side by side at regular intervals. As shown in FIG. 6, each vertical fin 21 has a pivot 22 projecting from the upper and lower parts, and the upper and lower pivots 22 are inserted into shaft holes of bearing portions provided on the upper wall and the lower wall of the air passage 9. Is rotatably supported.

  In addition, a crank 23 is provided on the lower pivot 22 of each vertical fin 21, and one link bar 24 is connected to the biased shaft of the crank 23, and all the vertical fins 21 rotate in conjunction with each other. It has a structure to do. Further, as shown in FIGS. 4 and 7, the operation knob 5 is disposed so as to be exposed from the opening 1 a provided at the lower center of the bezel 1, and the shaft 5 a for the operation knob is vertically disposed at the center of the bottom of the bezel 1. The operation knob 5 is rotatably supported on the shaft 5a. On the rear part of the operation knob 5, a biasing shaft 5b projects downward. On the other hand, a link 25 provided with a bifurcated portion 25a is connected to the center of the link bar 24, and the bias shaft 5b of the operation knob 5 is engaged with the bifurcated portion 25a.

  Accordingly, when the operation knob 5 is rotated to the right, the vertical fins 21 of the rear movable louver 4 are rotated to the right via the link 25, the link bar 24, the crank 23, and the pivot shaft 22, and the wind direction is changed to the right. Adjust to. On the other hand, when the operation knob 5 is turned to the left, the vertical fins 21 of the rear movable louver 4 are turned to the left via the link 25, the link bar 24, the crank 23, and the pivot 22, and the wind direction is turned to the left. It comes to adjust.

  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 retainer 2 and the ventilation path 9 in the bezel 1 through the air outlet 10.

  As shown in FIG. 7A, the air flow straightens in the ventilation path 9 with the horizontal fins of the front movable louver 3 and the vertical fins 21 of the rear movable louver 4 parallel to the air blowing direction of the ventilation path 9. The air travels between the rear movable louver 4 and the front movable louver 3 and blows forward from the air outlet 10. At this time, the upper telescopic fin 12 and the lower telescopic fin 15 of the front movable louver 3 have their sliding fins 14 and 17 accommodated in the slit grooves 13b and 16b of the main body fins 13 and 16 up to an intermediate position. The front-rear width a1 of the fin 12 and the lower telescopic fin 15 has an intermediate length as shown in FIG.

  When the air blowing direction is adjusted up and down, the center horizontal fin 11 of the front movable louver 3 is held and rotated up or down. When the central lateral fin 11 is rotated downward, for example, as shown in FIG. 7B, the central lateral fin 11 faces downward, and the upper telescopic fin 12 and the lower telescopic fin connected via the crank 18 and the link bar 19. 15 is similarly turned downward and turned downward.

  At this time, the sliding fin 14 of the upper telescopic fin 12 enters and is accommodated in the slit groove 13b of the main body fin 13 by moving the guide shaft 14a engaged with the upper guide groove 2a. Thereby, the front-rear width a2 of the upper telescopic fin 12 is reduced as shown in FIG. For this reason, the upper extensible fin 12 can face downward without the rear end portion interfering with the wall surface of the ventilation path 9.

  On the other hand, the sliding fin 17 of the lower telescopic fin 15 is in a state of projecting rearward from the slit groove 16b of the main body fin 16 by the guide shaft 17a engaging and moving in the lower guide groove 2b. The front-rear width a3 of the lower elastic fin 15 is enlarged as shown in FIG. 7B, and the rear end of the enlarged lower elastic fin 15 faces the center of the ventilation path 9. For this reason, the airflow which flows from the center of the ventilation path 9 to the lower part is effectively guided downward by the wide lower expansion and contraction fins 15, so that downward blowing with good directivity can be performed.

  On the other hand, when the central lateral fin 11 is rotated upward, as shown in FIG. 7C, the central lateral fin 11 faces upward, and the upper telescopic fin 12 and the lower telescopic joint connected via the crank 18 and the link bar 19. The fin 15 is similarly turned up and turned upward.

  At this time, the sliding fins 17 of the lower expansion and contraction fins 15 are accommodated in the slit grooves 16b of the main body fins 16 by moving the guide shafts 17a engaged with the lower guide grooves 2b. The front-rear width of the lower telescopic fin 15 is reduced. For this reason, as shown in FIG. 7C, the lower extensible fin 15 can face downward without the rear end portion interfering with the wall surface of the ventilation path 9.

  On the other hand, the sliding fin 14 of the upper telescopic fin 12 is in a state of protruding backward from the slit groove 13b of the main body fin 13 by the guide shaft 14a engaging and moving with the upper guide groove 2a. The front-rear width of the upper elastic fin 12 is enlarged, and the rear end of the enlarged upper elastic fin 12 faces the center side of the ventilation path 9. For this reason, as shown in FIG.7 (c), the airflow which flows through the upper part from the center of the ventilation path 9 is bent upward effectively by the wide upper expansion-contraction fin 12, and it blows upward with favorable directivity. Can do.

  Thus, when the direction of the front movable louver 3 is adjusted upward or downward from the front, the upper elastic fin 12 or the lower elastic fin 15 adjacent to the wall surface of the ventilation path 9 is located at the rear end thereof toward the center of the ventilation path 9. The upper elastic fin 12 or the lower elastic fin 15 to be directed slides the guide shafts 14a and 17a of the sliding fins 14 and 17 in the upper and lower guide grooves 2a and 2b, and the sliding fins 14 and 17 move from the main body fins 13 and 16, respectively. Move to protrude backwards. For this reason, the front-rear width of the upper telescopic fin 12 or the lower telescopic fin 15 is increased, and the directivity of the wind when the front movable louver 3 is adjusted upward or downward can be improved.

  Furthermore, when the direction of the front movable louver 3 is adjusted upward or downward from the front, only the upper elastic fin 12 or the lower elastic fin 15 that directs the rear end of the fin toward the center side of the air passage 9 is the sliding fin 14, The lower expansion fin 15 or the upper expansion fin 12 that protrudes 17 and faces the rear end of the fin toward the wall surface of the air passage 9 has its sliding fins 17 and 14 accommodated in the main body fins 16 and 13 and its front and rear width. Shrinks.

  For this reason, the rear end of the upper telescopic fin 12 or the lower telescopic fin 15 is less likely to interfere with the wall surface of the air passage 9, and the width of the air passage 9 in the short direction is reduced to make the air outlet 10 an elongated shape. Even the slit type resistor can be rotated without causing the fins of the front movable louver 3 to interfere with the wall surface in the air passage 9. For this reason, in order to avoid the interference of the fins, it is not necessary to provide a notch recess in the wall surface of the air passage 9 or to enlarge the length of the air passage 9 in the short direction, and to reduce the outer shape of the register. it can.

  In the above embodiment, for the register having the horizontally long air outlet 10, the front movable louver 3 is provided with the upper telescopic fin 12, the central lateral fin 11 and the lower telescopic fin 15, and the rear movable louver 4 is provided with the vertical fin 21. Although they are in a state where they are rotated 90 degrees, they are made into a vertically long air outlet, a plurality of vertical fins are provided on the front movable louver, a plurality of horizontal fins are provided on the rear movable louver, and the vertical fins of the front movable louver are provided. It can also be configured as a telescopic fin.

The register of this example uses a front movable louver 8 provided with one type of expansion and contraction fins 32 in place of the three-sheet type front movable louver 3 described above. About the same part as the said embodiment, since the same figure code | symbol is attached | subjected in drawing, please refer to the above.

  The structure of the bezel 1 and the retainer 2 constituting the main part of the register is the same as described above, and a fitting portion (not shown) for connecting to the retainer 2 is provided on the back side of the bezel 1, The duct-like retainer 2 is fitted and connected. A ventilation path 9 is formed in the bezel 1 and the retainer 2, and the front movable louver 8 and the rear movable louver 4 are disposed in the ventilation path 9 so as to be orthogonal to each other with the expansion and contraction fins 32 and the vertical fins 21 orthogonal to each other. It is installed. As shown in FIGS. 10 and 12, a bearing portion 1 c for the front movable louver 3 is attached to the left and right side walls of the ventilation path 9 of the bezel 1, and the shaft hole provided in the bearing portion 1 c extends and contracts the front movable louver 3. The pivot 33a of the main body fin 33 of the fin 32 is rotatably supported.

  As shown in FIGS. 10 and 12, the front movable louver 8 is composed of a single expansion / contraction fin 32 disposed in the horizontal and horizontal directions. The expansion / contraction fin 32 slides relative to the main body fin 33 and the main body fin 33. The sliding fin 34 moves, and the sliding fin 34 is slid to expand and contract the front-rear width of the fin. A slit groove 33b is formed in the main body fin 33 of the expansion and contraction fin 32 from the back surface to the front surface, that is, parallel to the plane and opened to the back surface, and the sliding fin 34 is formed in the slit groove 33b in the front-rear direction of the fin. The sliding fin 34 is slidably inserted, and the sliding fin 34 enters and exits from the main body fin 33 so that the front-rear width of the telescopic fin 32 is expanded and contracted.

  The telescopic fin 32 provided with the main body fin 33 and the sliding fin 34 is pivoted up and down by supporting the pivot shafts 33a and 33a projecting on both sides of the main body fin 33 on the bearing portion 1c on the side wall of the air passage 9. In particular, when the rear end portion of the expansion and contraction fin 32 is directed to the side wall side of the ventilation path 9 with the direction of the expansion and contraction fin 32 directed in the vertical direction, the inside of the slit groove 33b of the main body fin 33 The sliding fin 34 protrudes rearward and moves, and the front-rear width of the telescopic fin 32 is increased. On the other hand, when the telescopic fin 32 is directed to the front of the register, that is, as shown in FIG. 13A, when the telescopic fin 32 is operated in a horizontal state, the front-rear width of the telescopic fin 32 is reduced. It has become.

  For this reason, the pivot shafts 33 a and 33 a at both end portions of the main body fin 33 of the expansion and contraction fin 32 are pivotally supported by the bearing portions 1 c on the side wall of the ventilation passage 9, and the guide shaft 34 a protrudes from both end portions of the sliding fin 34. The guide shaft 34 a is engaged with guide grooves 2 c formed on both side walls of the air passage 9. The shape of the guide groove 2c is formed in an arc shape as shown in FIGS. 12 and 13, and when the direction of the expansion and contraction fin 32 is adjusted in the vertical direction from the front, the guide shafts 34a and 34a pass through the guide grooves 2c and 2c. The sliding fins 34 are configured to slide and move backward from the main body fins 33.

  As shown in FIG. 12, an operation knob portion 33 c is provided at the front portion of the main body fin 33 to be used when the direction of the telescopic fin 32 of the front movable louver 8 is adjusted up and down.

  As described above, since the front movable louver 8 is composed of one expansion and contraction fin 32, the register is higher in height than the air blower outlet 10 and the ventilation path 9 (as compared with the case where a plurality of front movable louvers are provided. By reducing the vertical width, a flatter slit type register can be obtained.

  On the other hand, as shown in FIGS. 12 and 13, the rear movable louver 4 is disposed in the ventilation path 9 at the rear (back) of the front movable louver 8. In the rear movable louver 4, a plurality of vertical fins 21 are vertically arranged side by side at regular intervals. Each vertical fin 21 is provided with a pivot 22 at the upper and lower portions, and the upper and lower pivots 22 are inserted into shaft holes of bearing portions provided on the upper wall and the lower wall of the ventilation path 9 and supported so as to be pivotable to the left and right. ing.

  Since such a rear movable louver 4 is disposed behind (backward) the front movable louver 8, its position is far from the air outlet 10 of the register, and when the direction of the vertical fin 21 is swung left and right, As the position of the movable louver 4 is rearward, it is more difficult to bend the air blowing direction left and right. However, when the front movable louver 8 has the expansion and contraction fins 32 and is horizontally adjusted so that the expansion and contraction fins 32 face the front, the sliding fins 34 are accommodated in the main body fins 33 and the front and rear widths of the fins are reduced. Therefore, the position of the rear movable louver 4 can be moved forward by the reduced width of the telescopic fin 32. For this reason, the directivity of the wind at the time of adjusting the vertical fin 21 of the rear movable louver 4 in the left-right direction can be improved by bringing the position of the rear movable louver 4 closer to the air outlet 10.

  On the other hand, a crank 23 is provided on the lower pivot 22 of each vertical fin 21, and one link bar 24 is connected to the biased shaft of the crank 23, and all the vertical fins 21 rotate in conjunction with each other. It has a structure to do. Further, as shown in FIG. 10, the operation knob 5 is disposed so as to be exposed from the opening 1 a provided at the lower center of the bezel 1, and the shaft 5 a for the operation knob is provided in the vertical direction at the center of the bottom of the bezel 1. The operation knob 5 is rotatably supported on the shaft 5a. On the rear part of the operation knob 5, a biasing shaft 5b projects downward. A link 25 provided with a bifurcated portion 25a is connected to the center of the link bar 24, and the deflection shaft 5b of the operation knob 5 is engaged with the bifurcated portion 25a.

  As a result, when the operation knob 5 is turned to the right, the vertical fins 21 of the rear movable louver 4 are turned to the right via the link 25, the link bar 24, the crank 23, and the pivot shaft 22, and the wind direction is turned to the right. adjust. On the other hand, when the operation knob 5 is rotated to the left, the vertical fins 21 of the rear movable louver 4 are rotated to the left via the link 25, the link bar 24, the crank 23, and the pivot 22 to adjust the wind direction to the left. Configured to do.

  As shown in FIG. 13A, the register having the above-described configuration is configured so that the expansion and contraction fins 32 of the front movable louver 8 and the vertical fins 21 of the rear movable louver 4 are in parallel with the air blowing direction of the ventilation path 9 during the air blowing. The air flow goes straight through the ventilation path 9, passes between the rear movable louver 4 and the front movable louver 3, and is blown forward from the air outlet 10. At this time, the expansion fin 32 of the front movable louver 8 has its sliding fin 34 housed in the slit groove 33b of the main body fin 33, and the front-rear width a4 of the expansion fin 32 is shortened as shown in FIG. Yes.

  When the air blowing direction is adjusted up and down, the operation knob portion 33c of the telescopic fin 32 of the front movable louver 8 is held and rotated up or down. When the telescopic fin 32 is turned up or down, the main body fin 33 of the telescopic fin 32 rotates about the pivot 33a, and the guide shaft 34a of the sliding fin 34 engages with the guide groove 2c on the side wall. Accordingly, the sliding fin 34 moves so as to protrude rearward from the slit groove 33b of the main body fin 33. Thereby, even in the case of the single-type front movable louver 8, the front-rear width a5 of the expansion and contraction fin 32 is expanded as shown in FIG. The directivity of the wind when shaken can be improved.

  Further, as described above, when the expansion and contraction fins 32 are horizontally adjusted so as to face the front, the sliding fins 34 are accommodated in the main body fins 33 and the front and rear widths of the fins are reduced. The position of the rear movable louver 4 can be moved forward by the reduced width. Thereby, the position of the rear movable louver 4 can be brought as close to the air outlet 10 as possible, and the directivity of the wind when the vertical fins 21 of the rear movable louver 4 are adjusted in the left-right direction can be improved. .
