Description

  The present invention relates to a register for adjusting air blowing used in an air conditioner such as an automobile, and more particularly to a register for preventing sound hitting when a fin of a movable louver disposed in a ventilation path is rotated.

  A front movable louver and a rear movable louver are arranged in the retainer that forms the ventilation path as a register for air blow adjustment used for air outlets for air conditioning in automobiles, etc. When air is blown out from the air outlet, a register that adjusts the air blowing direction up, down, left, and right by changing the angle of each fin of the front movable louver and the rear movable louver is used in an air conditioner of an automobile or the like.

  As this type of register, the operation knob is slidably fitted on the front fin of the front movable louver, and a bifurcated engagement portion is provided on the rear upstream side of the operation knob. A register having a structure provided with an engagement shaft portion with which the bifurcated engagement portion is engaged is proposed in Patent Document 1 below.

  In this register, when the operation knob is slid on the front fin, the bifurcated engagement portion and the engagement shaft portion are engaged, and the rear fin of the rear movable louver is rotated around an axis orthogonal to the axis of the front fin. The rear fin swings in the sliding direction of the operation knob and operates to change the wind direction. The movement range of the operation knob on the front fin is such that a convex or step is provided on the surface of the front fin, and when the operation knob is slid to the movement limit on the front fin, a part of the operation knob is on the front fin surface. In this structure, the rotation position of the rear fin is stopped at the maximum deflection angle.

JP 2004-210117 A

  However, in a register that is actually manufactured, there is a dimensional variation within the dimensional tolerance of each part, the variation in the position of the convex or stepped portion of the front fin surface, or the size of the rear fin and the link bar that connects them. When the operation knob is slid to the movement limit due to variations or the like, the rotation stop angle of the rear fin may exceed the designed maximum swing angle.

  In such a register, when an overstroke occurs in the rotation of the rear fin during the sliding operation of the operation knob, the outer edge of the rear fin may hit the wall surface in the ventilation path. At this time, the outer edge of the rear fin is away from the support shaft and has a large radius of rotation, and its peripheral speed is relatively high. In addition, the outer edge of the rear fin made of a hard synthetic resin such as ABS resin is hard. Since it hits the wall surface of the retainer made of synthetic resin, there was a problem that the impact at the time of contact was great and an irritating sound was generated.

  The present invention solves the above-described problem, and prevents the occurrence of a hitting sound by preventing the fin from coming into contact with the wall surface when the operating knob is slid greatly to shake the movable louver. An object is to provide a register that can be used.

  The register according to the present invention is a register in which a movable louver that pivotally supports a plurality of fins in a ventilation path is provided, and the wind direction is changed by rotating the fins of the movable louver by a sliding operation of an operation knob. An engagement projection is provided on a support shaft provided on the fin body of the fin in a direction perpendicular to the support shaft, and a contact portion with which the engagement projection contacts with the maximum swing angle of the fin is the support shaft. Provided on the shaft bearing member, when the operation knob is slid to the vicinity of the movement limit, the engaging convex portion comes into contact with the corresponding contact portion, and the rotation of the fin is stopped by the contact of the engaging convex portion. It is characterized by doing.

  There is a case in which the size of the register parts varies and the outer edge of the fin hits the wall surface of the ventilation path when the operation knob is slid to the vicinity of the limit of movement. According to the above, even when the operation knob is slid to the movement limit, the engaging convex part comes into contact with the contact part as a stopper and the fin stops rotating before the edge part of the fin comes into contact with the wall surface. The edge of the fin does not abut against the wall portion of the ventilation path, and the hitting sound due to the abutment of the fin edge can be reliably prevented.

  Here, the bearing member is provided with a bearing concave portion around the shaft hole, the engagement convex portion is rotatably disposed in the bearing concave portion, and the contact portion with which the engagement convex portion abuts is, It can be provided on the side in the bearing recess.

  Further, here, the operation knob is slidably fitted to a front fin of a front movable louver disposed inside an air outlet of the register, and a rear movable louver having a plurality of rear fins orthogonal to the front fin is provided. Arranged on the upstream side of the front fin, the engaging projection protrudes from the support shaft of the rear fin, and the contact portion of the bearing member can be provided on the bearing member of the support shaft of the rear fin. .

  Here, it is preferable that the bearing recess of the bearing member is formed as a plate-like space continuous from the edge in the plane of the bearing member, and a shaft hole is provided in the bearing recess. According to this, when assembling the plurality of rear fins of the rear movable louver so as to be pivotally supported by the bearing member, the rear fin is fitted into the shaft hole while sliding the spindle of each rear fin within the bearing recess of the bearing member. The engaging convex portion can be positioned in the concave portion.

  Further, here, the engaging convex portion protruding from the support shaft of the rear fin has a round pointed head and can be formed to extend from the edge of the fin main body. According to this, the engagement convex portion can be easily formed integrally with the fin body, and the rear fin can be reliably stopped at the maximum deflection angle.

  According to the register of the present invention, when the operation knob is slid largely to the vicinity of the movement limit and the movable louver is shaken, it is possible to prevent the fin from coming into contact with the wall surface and to prevent the generation of a hitting sound.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. This register is configured by fitting a bezel 1 forming a design surface on the front surface of a retainer 2 having a ventilation path 8 formed therein, and the front surface of the bezel 1 has a deformed horizontally long air as shown in FIG. The blower outlet 11 is formed.

  The register as a whole is configured as a thin register that is horizontally long and has a short vertical width, and a front movable louver 3 having three front fins 31 arranged in the horizontal and lateral directions is vertically located immediately inside the air outlet 11. It is arranged so as to be rotatable. The rear movable louver 4 is disposed in the direction orthogonal to the front movable louver 3, that is, in the longitudinal direction, on the upstream side (rear side) of the front movable louver 3. As shown in FIG. 3, before and after the register, the bezel 1 side is front (F), the retainer 2 side is rear (R), and in the ventilation path 8, the downstream side is front and the upstream side is rear.

  As shown in FIG. 1, the front shape of the bezel 1 is formed in a deformed shape in which the upper left part is inclined, and an air outlet 11 having a similar shape is formed on the inside thereof. As shown in FIGS. 2 and 3, the locking pieces 12 protrude rearwardly on the upper and lower surfaces of the bezel 1, and the locking pieces 12 are attached to the locking portions 21 with the locking claws 21 a on the retainer 2 side. As a result of the fitting, the retainer 2 is fitted to the rear rear side of the bezel 1. As shown in FIGS. 5 and 7, the retainer 2 is a duct having a rectangular cross section, and its front part is formed in an enlarged shape, and a ventilation path 8 is formed inside.

  As shown in FIG. 5, the rear movable louver 4 is disposed on the rear side in the ventilation path 8, that is, on the upstream side of the front movable louver 3, and as shown in FIG. The fins 41 and 49 are rotatably arranged in parallel in the vertical direction and at the left and right. The second rear fin 49 from the right is formed by separating the fin body into two left and right, and an engagement shaft portion 49a is provided at the center position for engagement with the operation knob 5. As will be described later, the engagement shaft portion 49a engages with the bifurcated engagement portion 52 of the operation knob 5 that is slidably fitted onto the front fin 31 of the front movable louver 3, and the slide operation of the operation knob 5 causes the engagement shaft portion 49a to slide. The rear movable louver 4 rotates left and right around the upper and lower support shafts 43 and 44.

  The rear movable louver unit including the rear movable louver 4 is configured as shown in FIGS. 8 to 11, and the upper support shaft 43 of each rear fin 41 of the rear movable louver 4 arranged side by side is supported by the upper bearing member 6. The lower support shaft 44 is rotatably supported by the lower bearing member 7.

  The upper bearing member 6 is formed of a relatively soft synthetic resin such as polypropylene resin, for example, and as shown in FIG. 8, a bearing portion having shaft holes at predetermined intervals is formed on the lower surface thereof. As this bearing portion, a bearing recess 61 in a thin plate space is formed at a predetermined interval on the lower surface of the upper bearing member 6, and a shaft hole is formed near the center of each bearing recess 61. The support shaft 43 of each rear fin 41 is fitted into a shaft hole in the bearing recess 61 and is supported so as to be rotatable with an appropriate frictional resistance.

  Each bearing recess 61 as a thin plate-like space is formed in a substantially U-shaped plane that opens rearward as it is, and side portions on both sides of each bearing recess 61 are formed as stepped contact portions 63. On the other hand, as shown in FIG. 12, an engaging projection 45 is provided on the support shaft 43 of the rear fin 41 so as to project at a right angle to the shaft. The protruding engaging projection 45 is located in a bearing recess 61 on which the support shaft 43 is pivotally supported as a stopper. As a result, the contact portions 63 on both sides of the bearing recess 61 are engaged convexly as stoppers when the rear fin 41 is rotated to its maximum swing angle, that is, before the edge of the rear fin 41 contacts the wall surface. The portion 45 is in contact with the contact portion 63 and stops the rear fin 41. As shown in FIG. 14, the engaging convex portion 45 is provided so as to project only at the support shaft 43 of the rear fin 41 located on both sides at a right angle to the shaft, and is rotatably disposed in the bearing concave portion 61. Further, as shown in FIG. 12, the engaging convex portion 45 is formed so as to extend from the upper edge portion of the fin main body 42 of the rear fin 41, and the support shafts 43 and 44, the arm portion and the connecting shaft 46 are connected. When integrally molding with the fin main body 42 with synthetic resin, the engaging convex part 45 can be easily integrally molded and provided.

  As shown in FIG. 12, the fin body 42 of the rear fin 41 is formed in a substantially rectangular plate shape with a rear lower portion cut out into a substantially rectangular shape, and a support shaft 43 projects upward from the upper end portion of the fin body 42. The support shaft 44 protrudes downward at the lower end portion. An arm portion 48 protrudes laterally at a portion of the fin body 42 that is cut out into a substantially rectangular shape at the lower rear portion, and a connecting shaft 46 protrudes downward from the arm portion 48. As described above, on the side portion of the upper support shaft 43, the engagement convex portion 45 extends integrally with the upper edge portion of the fin body 42 at a right angle to the shaft of the support shaft 43.

  As shown in FIG. 12 (b), the planar shape of the engaging convex portion 45 is formed with a rounded pointed head, and as shown in FIGS. When rotated to the maximum deflection angle, the vicinity of the tip of the engagement convex portion 45 abuts against the abutting portions 63 on both sides of the bearing concave portion 61, and the rear fin 41 stops within the maximum deflection angle. That is, the position, size, and shape of the engaging convex portion 45 are such that when the operation knob 5 is slid to the vicinity of the movement limit and the rear fin 41 is rotated to the front of its maximum swing angle, the engaging convex portion 45 is Even when the rear fin 41 stops by contacting the contact portion 63 and the operation knob 5 is overstroked (for example, moved beyond a predetermined slide distance) due to variations in the dimensions of the register components, the rear fin 41 Is stopped before hitting the wall surface in the retainer 2.

  As shown in FIGS. 8 and 14, in this embodiment, only the two rear fins 41 located at both ends of the rear movable louver 4 are provided with the engaging projections 45 protruding from the upper support shaft 43. However, of course, it is also possible to provide the engaging convex portion 45 on the support shaft 43 of all the rear fins 41 of the rear movable louver 4.

  When each component is manufactured at the time of manufacturing the register, the rear fin 41 shown in FIG. 12 is formed using a relatively hard synthetic resin such as an ABS resin, and the engaging convex portion 45 is also formed of the same hard synthetic resin. It is integrally formed with. On the other hand, the contact portion 63 of the upper bearing member 6 is formed from a relatively soft synthetic resin such as polypropylene resin as described above. For this reason, at the maximum deflection angle of the rear fin 41, the impact when the engaging convex portion 45 abuts against the abutting portion 63 is suppressed, and almost no sound is generated. Further, the circumferential speed of the engaging convex portion 45 when the rear fin 41 is rotated is relatively low because the position is close to the support shaft 43, so that almost no hitting sound is generated.

  The lower bearing member 7 that supports the lower support shaft 44 of the rear movable louver 4 is formed in a horizontally long shape as shown in FIGS. 8, 9, and 11, and corresponds to the lower support shaft 44 of each rear fin 41. A shaft hole is provided at a position to be used. The support shaft 44 of each rear fin 41 is rotatably inserted in each shaft hole of the lower bearing member 7 and is supported by the shaft. The lower bearing member 7 is integrally molded from a relatively soft synthetic resin such as polypropylene resin, for example, like the upper bearing member 6. The rear movable louver unit including the rear fins 41 and 49 that are pivotally supported between the upper bearing member 6 and the lower bearing member 7 is assembled as shown in FIGS. 8 to 11, and in that state, in the ventilation path 8 of the retainer 2. It is inserted into the fixed position and assembled.

  On the other hand, as shown in FIGS. 1 and 7, on the downstream side (front side) of the rear movable louver 4 in the ventilation path 8, the front movable louver 3 composed of three front fins 31 is in the vicinity of the inside of the air outlet 11. In addition, it is pivotally supported in the horizontal lateral direction so that it can be pivoted (tilted) up and down.

  Each front fin 31 of the front movable louver 3 has a support shaft 32 projecting from both ends of the fin body, and the support shaft 32 is fitted into a bearing portion provided on the side wall of the bezel 1 or a bearing portion inserted into the bezel 1. And supported so as to be rotatable about a horizontal support shaft 32. A connecting shaft 34 as shown in FIG. 13 is provided at the end of each front fin 31 so as to be offset from the support shaft 32, and one link bar 33 is connected to these connecting shafts 34. Both the front fins 31 rotate in conjunction with each other.

  As shown in FIGS. 1 and 7, the operation knob 5 is fitted on the front fin 31 located at the center of the air outlet 11 so as to be slidable in the horizontal horizontal direction which is the longitudinal direction. The operation knob 5 is exposed to the front of the register, and when the operation knob 5 is held and rotated up and down, the front movable louver 3 rotates up and down, and when the operation knob 5 is slid left and right, the rear movable louver 4 Is designed to rotate left and right.

  As shown in FIG. 13, the operation knob 5 is fitted to the front fin 31 so as to be slidable by inserting the front fin 31 into an insertion long hole provided in the knob main body 51. In order to guide the slide of the operation knob 5, a guide groove 35 is provided at the edge of the front fin 31, and a guide convex portion 53 that engages with the guide groove 35 is provided inside the operation knob 5. The guide convex portion 53 of the front fin 31 engages with the guide groove 35 of the front fin 31 to guide the slide. An operation load applying material is accommodated in the operation knob 5 in contact with a part of the front fin 31 to apply an operation load during sliding.

  Further, as shown in FIG. 13, a bifurcated engagement portion 52 is provided at the rear portion (upstream side) of the operation knob 5 toward the rear side (upstream side). The bifurcated engagement portion 52 is made of a bifurcated (fork-shaped) member, and engages the bifurcated member by causing the engagement shaft portion 49a of the rear fin 49 to enter. Thus, when the operation knob 5 slides to the left and right, the engagement shaft portion 49a and the forked engagement portion 52 are engaged to rotate the rear fins 41 and 49 to the left and right as shown in FIGS. It is.

  As shown in FIG. 8, the rear fin 49 for engagement of the rear movable louver 4 is composed of two fin bodies, and an engagement shaft portion 49 a is vertically provided at the center front portion thereof. Engage with the joint 52. As a result, when the operation knob 5 is slid to the right, the rear fin 41 of the rear movable louver 4 swings to the right, and when the operation knob 5 is slid to the left, the rear fin 41 of the rear movable louver 4 swings to the left. On the other hand, when the front movable louver 3 is swung up and down, when the front fin 31 is turned up and down around the support shaft 32 by holding the operation knob 5, the three front fins 31 are moved around the support shaft 32. It will swing up and down.

  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 8 in the retainer 2 through the air outlet 11.

  As shown in FIGS. 1 and 14, when the operation knob 5 is in a horizontal state at the center position and air is blown, the air flow passing through the ventilation path 8 passes through the rear fins 41 and 49 of the rear movable louver 4, Further, it passes through the front fins 31 of the front movable louver 3 and is blown forward in the front.

  On the other hand, when changing the air blowing direction up or down, the operation knob 5 is held and rotated (tilted) up or down. When the operation knob 5 is held and rotated up or down, the front fin 31 in which the operation knob 5 is inserted rotates up or down around the support shaft 32, and the blowing direction is changed to the upper side or the lower side. It is done.

  On the other hand, when the air blowing direction is changed to the left or right, the operation knob 5 is slid left or right to change the air direction to the left or right. At this time, when the operation knob 5 is held and slid to the right or left, the operation knob 5 slides on the front fin 31 and moves in the horizontal direction (lateral direction), and the operation knob 5 and the forked engagement portion 52 are moved. The rear movable louver 4 moves in the same direction while being engaged with the engagement shaft portion 49a of the rear fin 49. Along with this, the rear fin 49 of the rear movable louver 4 receives the operation force of the operation knob 5 and rotates to the right about the support shafts 43 and 44, and the rotation is via the connecting shaft 46 and the link bar 47. , Transmitted to the other rear fin 41, and all the rear fins 41, 49 of the rear movable louver 4 are rotated right or left around the support shafts 43, 44 as shown in FIGS. The wind direction is swung to the right or left.

  At this time, when the operation knob 5 is slid to the vicinity of the left and right movement limits, as shown in FIGS. 15 and 16, the engaging convex portion 45 protruding from the support shaft 43 of the rear fin 41 is brought into contact with the abutting portion 63. The rear fins 41 and 49 stop rotating due to the contact. At this time, as shown in FIGS. 15 and 16, the rear fin 41 stops just before contacting the wall surface in the ventilation path 8 of the retainer 2.

  For this reason, for example, when there is a variation in dimensions for each product and the operation knob 5 slides more than the design stroke during the slide operation and becomes an overstroke, the rear fins 41 and 49 of the rear movable louver 4 are 15. As shown in FIG. 16, the engaging convex portion 45 serves as a stopper to contact the contact portion 63, and the support shaft 43 stops. Thereby, the outer edge part of the rear fin 41 does not contact | abut on the wall surface of the retainer 2, and an unpleasant hitting sound does not generate | occur | produce.

  As described above, when the register parts have variations in dimensions and the operation knob 5 is largely slid to the vicinity of the movement limit, even if an overstroke occurs, the outer edge of the rear fin 41 is placed on the wall surface of the retainer 2. Before the contact, the engaging convex portion 45 contacts the contact portion 63 as a stopper, and the rotation of the rear fin 41 stops. Therefore, even when the operation knob 5 is slid to the movement limit, the outer side of the rear fin 41 is stopped. The edge portion does not come into contact with the wall portion of the ventilation path 8, and it is possible to reliably prevent the hitting sound caused by the contact of the edge portion of the rear fin 41.

  In addition, this invention is not limited to the said embodiment, It can implement also with the following forms.

  In the above embodiment, the bearing recess 61 is provided in the upper bearing member 6 and the contact portion 63 is provided on the side thereof. However, the contact recess can also be provided in the bearing recess of the lower bearing member 7, and the bearing recess is provided. Alternatively, the contact portion can be provided on the bearing member.

  Moreover, in the said embodiment, although it was set as the structure which prevents generation | occurrence | production of the hitting sound by the rear fin 41 of the rear movable louver 4, the generation | occurrence | production of the hitting sound by the fins of movable louvers other than the rear movable louver is similar to the above structure Can be prevented.

  Furthermore, although the said embodiment was set as the register | resistor which has the horizontally long air blower outlet of the left-right asymmetrical shape, it can also be made into the register | resistor which has a left-right symmetrical air blower outlet, or makes an air blower outlet vertically long shape, and is movable front The present invention can also be applied to a register having a vertically long air outlet in which vertical fins are arranged in the louver and a plurality of horizontal fins are arranged in parallel in the rear movable louver.

  In the above embodiment, the front movable louver 3 is provided with the three front fins 31. However, the front movable louver has only one front fin, or two or four or more front fins are arranged in parallel. The front fins can be linked by a crank portion, a connecting shaft and a link bar, and can be rotated by operating the operation knob.
