Description

  The present invention relates to a register that is used in an air outlet for ventilation or air conditioning in an automobile interior or the like, and that supports a damper plate in an air passage so that the damper plate can be opened and closed, and opens and closes the damper plate by operating a dial knob.

  As an air conditioning register for automobiles, a laterally movable louver and a longitudinally movable louver are arranged in the bezel to adjust the wind direction, etc., and the air flow is stopped or the air volume is adjusted at the rear of the ventilation path provided with the movable louver. A register provided with a damper plate that can be opened and closed is known in Patent Document 1 below.

  The damper mechanism used in this register is such that a damper plate is pivotally supported in the ventilation path, and a dial knob for manual operation is pivotally supported on the front side of the retainer, and a tooth portion provided at the rear of the dial knob. In addition, the damper arm is linked and connected to the shaft of the damper plate, and the damper plate is rotated by the operation of the dial knob to stop the blowing or adjust the air volume.

  By the way, in this type of resistor damper mechanism, in order to smoothly rotate the damper plate by manually operating the dial knob, between the bearing hole of the boss portion of the dial knob and the support shaft on the retainer side, In addition, a certain amount of clearance is created between the support shaft of the damper plate and the shaft hole of the retainer that serves as the bearing portion to prevent biting of the shaft due to dimensional variation within the dimensional tolerance range of each part, and smooth The damper plate can be rotated.

  However, the gap between the bearing hole of the dial knob boss and the support shaft on the retainer side, or between the support shaft of the damper plate and the shaft hole of the retainer serving as the bearing portion is caused by a dimensional error or the like. When the size is increased, the member that connects the dial knob and the damper plate vibrates due to the vibration of the automobile, the flow of wind, and the like, and there is a problem that abnormal noise is easily generated.

Therefore, as described in Patent Document 2 below, the present applicant makes the support shaft of the damper plate perpendicular to the shaft by a spring member such as a linear spring or a leaf spring with respect to the retainer that is the bearing portion. We proposed a register that urges it in the direction and presses it to prevent the generation of noise due to vibration.
Japanese Utility Model Publication 1-148553 JP 2007-106352 A

  The support shaft of the damper plate of this register is urged by a spring member in the direction perpendicular to the shaft and pressed against the bearing. Even if there is a gap between the shaft and the bearing, noise is generated due to vibration. However, for this reason, a spring member that biases the support shaft is necessary, and the assembly man-hours for assembling the spring member are required, which increases the manufacturing cost of the register. was there.

  The present invention has been made in view of the above points, and prevents the vibration and noise of the damper plate and the mechanism for operating the rotation without increasing the number of parts and without increasing the manufacturing cost. An object of the present invention is to provide a register capable of performing the above.

  According to a first aspect of the present invention, a damper plate is pivotally supported in the air passage of the retainer so that the damper plate can be opened and closed, and a damper lever portion is provided outside a damper support shaft that rotatably supports the damper plate. A dial knob for plate operation is pivotally supported by a part of the retainer, and a knob lever portion is provided for transmitting the turning force of the dial knob to the damper plate. The damper lever portion and the knob lever portion are guided by In a register that is linked by engagement of a groove and a pin and opens and closes the damper plate by operating the dial knob, a rubber seat is attached to the base of the pin, and the rubber seat is connected to the guide groove. The damper lever portion is pressed against the knob lever portion or the damper lever portion on the side so as to slightly bend the damper support shaft.

  According to this device, the rubber lever seat attached to the pin urges the damper lever portion in a direction slightly bending the damper support shaft, so that there is a gap between the damper support shaft and the shaft hole of the retainer. Even in such a case, the vibration of the automobile or the vibration caused by the wind in the ventilation path is prevented from being transmitted to the damper support shaft and the damper lever portion.

  Therefore, it is possible to prevent rattling and abnormal noise due to vibration of the damper support shaft and the damper lever portion. In addition, the rubber-like seat part can be attached and molded by insert molding, for example, so as to cover the base part of the thermoplastic elastomer, etc., so that it is carried out at an inexpensive manufacturing cost without increasing the number of parts. Can do.

  According to a second aspect of the present invention, in the first aspect of the present invention, a ridge is formed on the retainer side surface of the knob lever portion, and the ridge contacts and slides on the side surface of the retainer when the knob lever portion rotates. The guide protrusion to be provided is provided along the rotating direction of the knob lever portion.

  According to this device, when the rubber-like seat portion presses the damper lever portion in the bending direction of the damper support shaft, the knob lever portion receives the reaction force from the guide protrusion via the protrusion, and the damper is more effectively performed. It is possible to prevent vibration of the support shaft and the damper lever part, and to prevent rattling and abnormal noise due to vibration.

  In the invention of claim 3, in the invention of claim 2, the guide ridge on which the ridge contacts and slides, at a position where the ridge is inserted at the fully open position and the fully closed position of the damper plate, A groove for generating a moderation feeling is formed.

According to this device, when the damper plate is fully closed or fully opened by operating the dial knob, a feeling of moderation is generated, and the damper plate can be reliably stopped and held at the fully closed position or the fully open position. .

  According to the register of the present invention, even if there is a gap between the damper support shaft and the shaft hole of the retainer, the damper lever portion is urged by the rubber-like seat portion in the direction of bending the damper support shaft. It is possible to prevent the damper plate and the damper support shaft from vibrating due to the wind in the ventilation path, and it is possible to prevent rattling and abnormal noise due to the vibration. In addition, since the rubber-like seat portion to be urged can be attached by insert-molding, for example, a thermoplastic elastomer so as to cover the base portion of the pin, the number of parts is not increased and the manufacturing cost is low. Can be implemented.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a register for air conditioning mounted on an instrument panel or the like of a vehicle, FIG. 2 is a sectional view taken along the line II-II, and FIG. 3 is a left side view of the register.

  This register includes a retainer 2 formed in a duct shape having a square cross section and a bezel 1 fitted to the front portion of the retainer 2. The lower portion of the retainer 2 protrudes from the front and the upper portion is rearward. It is formed in a slanted shape that is retracted, and a ventilation path 2 a is formed in the retainer 2. An air outlet 1a and a knob opening 1b for a dial knob are provided on the front surface of the bezel 1 which is attached to the front portion of the retainer 2 at an angle.

  A damper plate 8 of a damper mechanism is disposed in the rear part of the ventilation path 2a in the retainer 2 so as to be capable of rotating operation in order to stop air blowing or adjust the air volume. A damper shaft portion 8 b is projected from one side portion of the damper plate 8, and the damper shaft portion 8 b is rotatably fitted in a recess provided on the side wall of the retainer 2. The damper plate 8 is formed in a plate shape, and a soft edge portion 8a such as a sponge sheet is attached to the edge portion thereof. When the damper plate 8 is closed, the soft edge portion 8a is brought into contact with the inner peripheral surface of the air passage 2a to provide a sealing property. Good.

  The other end portion of the damper plate 8 is fitted with a tip end portion of a damper support shaft 9 inserted from the outside into the insertion hole 2b of the retainer 2, and the damper plate 8 includes the damper support shaft 9 and the damper shaft. It is rotatably supported by the portion 8b. As shown in FIG. 5, a fitting portion 9 c is provided at the tip of the damper support shaft 9, and the fitting portion 9 c of the damper support shaft 9 is fitted and fixed to the left edge portion of the damper plate 8.

  When the damper plate 8 is mounted in the retainer 2, the damper shaft portion 8 b is first fitted into the retainer 2, and the damper support shaft 9 is inserted from the outside of the insertion hole 2 b (FIG. 5) provided in the left side wall of the retainer 2. 2, the tip fitting portion of the damper support shaft 9 is fitted to the left side edge portion of the damper plate 8. A certain amount of gap is provided between the damper support shaft 9 and the insertion hole 2b in consideration of a dimensional error and rotation within the dimensional tolerance range of each member. As will be described later, the vibration of the damper support shaft 9 due to the gap is caused by slightly bending the damper support shaft 9 by pressing the damper lever portion 9a of the damper support shaft 9 toward the retainer side (inner side). I try to prevent it.

  As shown in FIG. 5 and the like, a damper lever portion 9a extends in the direction perpendicular to the outer end portion of the damper support shaft 9, and a guide groove 9b is formed in the damper lever portion 9a along the longitudinal direction. The A pin 15 of a knob lever portion 13 (to be described later) is fitted in the guide groove 9b, so that the turning operation force of the dial knob 10 is transmitted to the damper lever portion 9a. Here, the guide groove 9b is a concept including a bottomed elongated hole (concave line) and a penetrating elongated hole.

  On the other hand, as shown in FIGS. 2 and 5, a dial knob 10 is pivotally supported by a knob support shaft 7 on the left side surface of the front portion of the retainer 2 so that the damper plate 8 can be rotated. Has been. The dial knob 10 has a knob body 11 having a substantially wheel shape. The dial body 10 is formed by covering a soft skin portion 14 on the front portion of the knob body 11. In addition to having a hole, an operation load applying portion (rubber-like elastic body) for applying an operation load is provided.

  Further, a knob lever portion 13 is provided on the knob main body 11 of the dial knob 10 so as to extend toward the back side thereof, and a pin 15 is provided at the tip of the knob lever portion 13 toward the outside (on the side opposite to the retainer) and the knob support shaft 7. It is set up substantially in parallel. A rubber seat 16 made of a thermoplastic elastomer or the like is attached to the base portion of the pin 15 so as to cover the portion.

  The rubber-like seat portion 16 is formed in a substantially truncated cone shape, and when the pin 15 is fitted in the guide groove 9b of the damper lever portion 9a, the damper lever portion 9a is pressed outward (on the side opposite to the retainer) as shown in FIG. That is, the damper lever portion 9a is pressed in a direction in which the damper support shaft 9 is slightly bent. Note that the entire pin 15 may be covered with a rubber-like elastic covering layer, and the covering layer may be integrated with the rubber-like seat 16.

  Further, as shown in FIG. 4, a protrusion 17 is projected along the longitudinal direction of the knob lever portion 13 on the back surface (retainer side surface) of the tip portion (near the pin 15) of the knob lever portion 13. The ridge 17 slides in contact with the guide ridge 18 on the retainer 2 side, and the knob lever portion 13 of the dial knob 10 is placed on the guide ridge 18 projecting from the side wall of the retainer 2. The structure is set by pressing 17.

  That is, a protrusion 17 is formed on the retainer side surface of the knob lever portion 13, and a guide protrusion 18 on which the protrusion 17 abuts and slides when the knob lever portion 13 rotates on the side surface of the retainer 2. It is provided along 13 rotation directions. When the boss portion 12 of the dial knob 10 is fitted into the knob support shaft 7 and the pin 15 at the tip of the knob lever portion 13 is set by engaging with the guide groove 9b of the damper lever portion 9a, the knob lever portion 13 is rubber-like. The ridge 17 is pressed against the guide ridge 18 projecting from the side wall of the retainer 2 by the seat portion 16 and set.

  As a result, as shown in FIG. 4, the rubber seat 16 presses the damper lever 9a outward (on the side opposite the retainer), and the damper support shaft 9 has an insertion hole (having its axis Cs formed in the side wall of the retainer. It is bent from the axis C of the shaft hole 2b by a slight angle θ. At this time, the knob lever portion 13 receives a reaction force from the retainer 2 side via the protrusion 17 and the guide protrusion 18, and effectively applies the pressing force (biasing force) of the rubber seat 16 to the damper lever portion 9 a. I can tell you. This slight bending of the damper support shaft 9 prevents the vibration of the damper support shaft 9 and the damper plate 8 and prevents the occurrence of rattling and abnormal noise due to the vibration.

  The knob main body 11 of the dial knob 10 is formed into a predetermined shape by a hard synthetic resin such as PVC at the time of manufacture, but the operation load applying portion of the boss portion 12, the soft skin portion 14, and the rubber seat portion. 16 can be manufactured at a time by insert molding using a soft synthetic resin such as a thermoplastic elastomer with the knob body 11 molded in advance as an insert. As the thermoplastic elastomer, polyolefin, polyurethane, styrene, ethylene, butylene, a copolymer, or the like can be used. Thus, since the rubber-like seat part 16 is shape | molded with the soft skin part 14 and the operation load provision part by insert molding at the time of manufacture of the dial knob 10, it is necessary to shape | mold a rubber-like seat part as another component. In addition, manual assembly is not required and the manufacturing cost is not increased.

  As shown in FIG. 2 and the like, a knob support shaft 7 projects from the left side wall portion of the retainer 2, and the dial knob 10 is rotatably supported on the knob support shaft 7. On the other hand, as shown in FIG. 5, the dial lever 10 is provided with the knob lever portion 13 projecting sideways as described above, and the pin 15 provided at the tip of the knob lever portion 13 is connected to the guide groove 9b of the damper lever portion 9a. The guide groove 9b enters and engages from the inside to the outside.

  When the pin 15 and the guide groove 9b are engaged with each other, as shown in FIG. 4, a truncated cone-shaped rubber seat 16 is attached to the base of the pin 15, so that the rubber seat The portion 16 presses the damper lever portion 9a outward (toward the non-retainer side). Due to the pressing of the damper lever portion 9a by the rubber-like seat portion 16, the damper support shaft 9 is bent at a slight angle as shown in FIG. 4, and vibration and rattling due to the gap between the insertion hole 2b and the damper support shaft 9 are caused. It will be resolved.

  A front movable louver 3 is disposed between the front portion of the retainer 2, that is, between the bezel 1 and the retainer 2, and a rear movable louver 4 is disposed behind (backward) the front movable louver 3. The front movable louver 3 has a plurality of horizontal fins 3a arranged at regular intervals, and each horizontal fin 3a is rotatably held at the front portion of the retainer 2 via the shafts on both sides. Further, as shown in FIG. 2, a crank 3b is provided on one shaft of each horizontal fin 3a, one link bar 3c is connected to the tip of the crank 3b of each horizontal fin 3a, and all the horizontal fins 3a are connected. It is structured to change its direction up and down in synchronization.

  The rear movable louver 4 has a plurality of vertical fins 4a arranged at regular intervals, and each vertical fin 4a is rotatably held at the front portion of the retainer 2 via a vertically projecting shaft. Also, a crank 4b is provided on the shaft below each vertical fin 4a, and one link bar 4c is connected to the tip of each crank 4b, so that all the vertical fins 4a can be synchronously changed in direction to the left and right. It has a structure. Further, a rod-like linkage portion is provided at the front portion of the vertical fin 4a located substantially at the center, and engages with a bifurcated linkage portion provided at the rear portion of the slide knob 5, so that the slide knob 5 is moved in the left-right direction. When it is slid, the direction of the vertical fins 4a of the rear movable louver 4 is adjusted to the left and right.

  The slide knob 5 is slidably fitted on the lateral fin 3a at the substantially center of the front movable louver 3 so as to protrude forward. The slide knob 5 adjusts the direction of the horizontal fins 3a of the front movable louver 3 up or down by rotating up and down, and through the linkage portion by sliding the slide knob 5 in the left-right direction. The left and right directions of the vertical fins 4a of the rear movable louver 4 are adjusted to the left or right.

  The register having the above-described configuration is attached to an instrument panel or a dashboard in an automobile so that the end of the retainer 2 is connected to a ventilation duct (not shown). The air sent from the ventilation duct is blown out from the ventilation path 2a in the retainer 2 through the air outlet 1a.

  When adjusting the air blowing direction up or down, when the slide knob 5 is operated up or down, the horizontal fins 3a of the front movable louver 3 rotate and the direction changes up and down, and the air blowing direction. Is adjusted up and down.

  When adjusting the air blowing direction to the left and right, if the slide knob 5 is operated to the right or left, the vertical fins 4a of the rear movable louver 4 rotate about the upper and lower rotating shafts, and the left and right directions are It changes in a predetermined angle range, and the blowing direction of air is adjusted to right and left.

  When the air flow is stopped or throttled or the ventilation path 2a is opened, the dial knob 10 located at the front left end of the bezel 1 is pushed with a finger or the like and turned up or down. At this time, the dial knob 10 rotates around the knob support shaft 7.

  The turning force of the dial knob 10 is transmitted from the knob lever portion 13 to the damper plate 8 via the pin 15, the guide groove 9b, the damper lever portion 9a, and the damper support shaft 9, and the damper plate 8 moves in the closing direction of the ventilation path 2a. Or rotate in the opening direction. At this time, as shown in FIG. 4, the rubber seat 16 attached to the base portion of the pin 15 is in contact with the damper lever portion 9a on the guide groove 9b side so that the damper support shaft 9 is slightly bent. Since the damper lever portion 9a is pressed, even if there is a gap between the damper support shaft 9 and the insertion hole 2b of the retainer 2, the vibration of the automobile or the vibration caused by the wind in the ventilation path 2a is applied to the damper support shaft 9 and the damper lever portion 9a. It is prevented from being transmitted. As a result, rattling and abnormal noise due to vibration of the damper support shaft 9 and the damper plate 8 can be prevented.

  Further, when the damper lever portion is rotated, the rubber seat portion 16 at the base of the pin 15 presses the damper lever portion 9a outward, and at this time, the protrusion 17 provided on the retainer 2 side surface of the knob lever portion 13 is Since the side surface of the retainer 2 slides in contact with the guide ridge 18, the rubber seat 16 effectively utilizes the reaction force from the guide ridge 18 via the ridge 17 to effectively lift the damper lever portion 9 a. It can be pressed outward.

  Further, when the damper plate 8 is operated to the fully closed position, the dial knob 10 is rotated in the direction of the arrow (downward) in FIG. 3, but when the damper plate 8 is fully closed, the ridge 17 is guided by the guide protrusion. Since it is inserted into the groove 18a (FIG. 5) of the strip 18, a sense of moderation can be generated, the dial knob 10 can be stopped, and the damper plate 8 can also be reliably stopped and held in its fully closed position. Further, when the damper plate 8 is operated to the fully open position, the dial knob 10 is rotated in the direction indicated by the arrow in FIG. 3, but when the damper plate 8 is fully opened, the protrusion 17 is the groove of the guide protrusion 18. Since it fits in 18b (FIG. 5), a sense of moderation can be produced, the dial knob 10 can be stopped, and the damper plate 8 can also be reliably held in its fully open position.

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