JP-A-11-198646

  However, according to the conventional Finshut register, when the operator rotates the operation knob, the sensation that the operator receives from the operation knob is almost constant over the entire rotation range of the operation knob. However, there is a problem that the operator cannot realize that the operation of rotating the operation knob in the closing direction is completed even though the air outlet is closed.

  In addition, when the air outlet is in an open state close to the closed state, an abnormal noise, a so-called whistling noise, is generated, and the entire air outlet is automatically closed by the strong air pressure, and air is blown out from the air outlet. There is a problem that it may occur.

  The present invention solves the problems of the prior art as described above, and the operator can easily realize that the operation of turning the operation knob in the closing direction is completed and the air outlet is closed. It is a first object to provide a click-sensing mechanism for a fin-shut register that can be used. In addition, the present invention prevents the generation of an abnormal noise when the air outlet is in an open state close to the closed state, so-called whistle blowing noise, and prevents the air outlet from being automatically closed due to a strong air pressure. It is a second object of the present invention to provide a click-sensing mechanism for a fin shut register that can be used.

  The click-sensing mechanism of the fin shut register according to the present invention includes a plurality of fins arranged in parallel to each other, an operation knob provided on any one of the fins and rotated by an operator, and the fins connected to each other. And a connecting means for changing the inclination angle of each fin in conjunction with the rotation operation with respect to the operation knob, and when the rotation operation in the direction of closing the air outlet with respect to the operation knob is completed, In the fin shut register in which the air blowing port is closed by the whole fin through the connecting means, from one end of the rotation shaft of the fin provided with the operation knob, the direction perpendicular to the rotation shaft The elastic arm portion extends from the front side of the angular position where the elastic arm portion generates a whistling sound to the housing side in the closing direction with respect to the operation knob. A deformation imparting portion is provided for repeatedly elastically deforming and elastically returning the elastic arm portion a plurality of times within a range in which the rotation operation is completed before the angular position where the rotation operation is completed, and the deformation imparting portion is based on the blowing air pressure. The elastic arm portion is configured to be capable of restricting the rotation of the elastic arm portion.

  In the click-sensing mechanism of the fin shut register according to the present invention, when the operator rotates the operation knob to close the air blowing port, the elastic arm portion is in front of the angular position where the whistling sound is generated. During the rotation to the position before the angular position where the rotation operation in the closing direction is completed, the deformation imparting unit repeatedly elastically deforms and elastically returns a plurality of times. The repetition of elastic deformation and elastic return of the elastic arm part is transmitted to the operator as a click feeling, and the operator feels this click feeling and the rotation operation is completed, and the air outlet is closed. Can be easily recognized. In other words, the operator can easily recognize that the air outlet is not yet closed while not feeling a click.

  In addition, when the fin starts to automatically rotate in the closing direction due to the strong blowing air pressure, the elastic arm portion comes into engagement with the deformation imparting portion through the connecting means by the rotation of the fin. Can no longer be rotated by the deformation imparting portion. For this reason, the automatic rotation of the fin is stopped and the air outlet is not closed. Moreover, since the rotation stop position of the fin is before the whistling sound is generated, no whistling sound is generated.

  Here, the elastic arm portion has an arc-shaped deformation portion formed concentrically with the rotation shaft on the base side, and the deformation imparting portion protrudes from the outer surface of the housing. The arc-shaped deformable portion is elastically deformed when the tip protruding portion of the arc-shaped deformable portion gets over the protruding portion of the boss portion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an exploded perspective view of a fin-shut register having a click feeling mechanism according to an embodiment of the present invention, FIG. 2 is a perspective view of a lateral fin provided with an operation knob, and FIGS. Explanatory drawing showing the transition of the positional relationship between the elastic arm portion and the boss portion when the operation knob is turned in the closing direction is shown.

  In FIG. 1, the fin shut register includes a rectangular tubular retainer 1 as a housing.

  Although not shown, five through holes are formed in the ceiling portion 1a of the retainer 1 in the lateral direction, and the upper end rotation shaft portion 2a of the vertical fin (back fin) 2 is rotatable in each through hole. It is inserted. Also, the floor 1b of the retainer 1 is formed with five grooves 1c that open forward in the horizontal direction, and the lower end pivot shaft 2b of the vertical fin 2 is rotatably fitted in each groove 1c. Is done.

  The five vertical fins 2 are connected to each other by fitting a pin 2 c protruding from the upper end surface of each vertical fin 5 into the through hole 3 a of the horizontal rod 3. Moreover, the rotation lever part 2d is extended in the back from the lower end rotation shaft part 2b of the vertical fin 2 located in the center. The rotating lever portion 2d is engaged with a rib 4a protruding from the upper surface of the rear portion of the substantially disc-shaped operation dial 4 that is rotated by an operator. The operation dial 4 is rotatably attached to the lower surface of the floor portion 1 b of the retainer 1, and the front portion of the operation dial 4, that is, the operation portion 4 b is opened at the lower end portion of the bezel 6 attached to the front surface of the retainer 1. It will be in the state protruded ahead from 6a.

  When the operator rotates the operation portion 4b of the operation dial 4, the rib 4a is fitted to the rotation hole 4c of the operation dial 4 (the rotation convex portion 1d provided on the lower surface of the retainer floor portion 1b). A circular lever movement is performed around the hole portion), and the rotating lever portion 2d rotates around the rotating shafts 2a and 2b of the central vertical fin 2 in conjunction with the circular arc movement of the rib 4a. The vertical fins 2 are rotated, and at the same time, the other vertical fins 2 are also rotated around the rotation shafts 2a and 2b via the horizontal rod 3. The rotation of each vertical fin 2 adjusts the wind direction in the left-right direction.

  At the front end of the left side wall 1e of the retainer 1, there are formed one groove 1f in the vertical direction and six through holes 1g sandwiching the groove 1f in the center, and each through hole 1g has a horizontal fin 5 (front The left end rotation shaft portion 5a of the fin) is rotatably inserted, and a shim 7 that rotatably holds the left end rotation shaft portion 5a of the lateral fin 5 located in the center is fitted in the groove 1f. The Further, seven grooves 1i opened forward are formed in the front end portion of the right wall portion 1h of the retainer 1 in the vertical direction, and the right end rotation shaft portion 5b of the horizontal fin 5 is rotated in each groove 1i. Can be fitted.

  The seven horizontal fins 5 are connected to each other by fitting a pin 5 c protruding from the right end surface of each horizontal fin 5 into the through hole 8 a of the vertical rod 8. The vertical rod 8 is disposed on the outer surface side of the right wall 1 h of the retainer 1. The horizontal fin 5 located at the center is formed with an operation knob 5d that is rotated by an operator.

  An elastic arm portion 5e extends from the right end rotation shaft portion 5b of the lateral fin 5 located at the center in a direction perpendicular to the right end rotation shaft portion 5b and rearward. The elastic arm portion 5e has an arc-shaped deformable portion 5f formed concentrically with the right end rotation shaft portion 5b, and the tip of the arc-shaped deformable portion 5f is constituted by a protruding portion 5g protruding inward.

  On the outer side surface of the right side wall 1h of the retainer 1, a boss 1j as a deformation imparting portion is projected. This boss portion 1j is formed along the locus of the arc motion drawn by the tip projection portion 5g of the arcuate deformed portion 5f of the elastic arm portion 5e when the operation knob 5d is turned, and the boss portion 1j Both end portions 1k and 1l are constituted by projecting portions protruding toward the arcuate deformed portion 5f so as to be able to contact the tip projecting portion 5g of the arcuate deformed portion 5f. Further, as shown in FIG. 2, a stopper 5 h that can come into contact with the front surface 8 b of the vertical rod 8 is formed on the right end rotation shaft portion 5 b of each horizontal fin 5, and one surface 5 i of the stopper 5 h is the vertical rod 8. When in contact with the front surface 8b, all the lateral fins 5 are substantially vertical and the air outlets 9 are closed (corresponding to the state shown in FIG. 5), and the other surface of the stopper 5h. When 5j comes into contact with the front surface 8b of the vertical rod 8, all the horizontal fins 5 are in a substantially horizontal state and the air outlets 9 are in an open state (corresponding to the state shown in FIG. 3). Each horizontal fin 5 can adjust the wind direction from a substantially horizontal wind direction to an obliquely downward wind direction depending on the inclination angle.

  When the air outlet 9 is opened in which the horizontal fins 5 are substantially horizontal, the elastic arm portion 5e is positioned farthest from the boss portion 1j as shown in FIG. When the operator rotates the operation knob 5d in the direction of pushing down the operation knob 5d from the open state, that is, in the closing direction, the central horizontal fin 5 rotates about the rotation shafts 5a and 5b. The horizontal fin 5 also rotates around the rotation shafts 5a and 5b. Along with the rotation of the central lateral fin 5, the arcuate deformed portion 5f of the elastic arm portion 5e starts an arc motion around the rotation shafts 5a and 5b. When the arcuate deformed portion 5f reaches the position shown in FIG. 4, the tip projection 5g of the arcuate deformed portion 5f comes into contact with one projection 1k of the boss 1j, and the tip projection 5g is the boss projection. The arcuate deformation portion 5f is elastically deformed so as to get over 1k. When the tip protrusion 5g finishes over the boss protrusion 1k, the arcuate deformed portion 5f is elastically restored. After this elastic return, the tip projection 5g of the arcuate deformed portion 5f is in contact with the other projection 11l of the boss 1j, and the tip projection 5g gets over the boss 11l. The portion 5f is elastically deformed. As shown in FIG. 5, when the tip protrusion 5g finishes over the boss protrusion 1l, the arcuate deformed portion 5f is elastically restored. When this elasticity is restored, one surface 5i of each stopper 5h comes into contact with the front surface 8b of the vertical rod 8, all the horizontal fins 5 are in a substantially vertical state, and the air outlet 9 is closed.

  As described above, when the operator rotates the operation knob 5d in the direction in which the operation knob 5d is depressed, that is, in the closing direction, the horizontal fins 5 in the substantially horizontal state start to rotate, and the tip protrusion 5g of the arcuate deformed portion 5f becomes the boss portion. When the projection 1g comes into contact with one projection 1k, the arcuate deformed portion 5f is elastically deformed so that the tip projection 5g rides over the boss projection 1k, and then elastically returns, and then the tip projection 5g becomes the boss 1j. When the abutment is in contact with the other projection 1l, the arcuate deformed portion 5f is elastically deformed so that the tip projection 5g gets over the boss projection 1l in the same manner as described above, and then elastically returns, so that each lateral fin 5 is substantially vertical. The air outlet 9 is closed.

  Here, one protrusion 1k of the boss 1j is a position where it comes into contact with the tip protrusion 5g of the arcuate deformed portion 5f when the elastic arm 5e is rotated to a position just before the angular position where the whistling sound is generated. In addition, the other protrusion 11 of the boss 1j is circular when the elastic arm 5e is rotated to a position just before the angular position where the rotation of the operation knob 5d in the closing direction is completed. It is formed at a position where it comes into contact with the tip protrusion 5g of the arcuate deformed portion 5f.

  For this reason, when the operator rotates the operation knob 5d to close the air outlet 9, the elastic arm portion 5e rotates in the closing direction from the angle position where the whistling sound is generated. While rotating to a position just before the angular position where the moving operation is completed, the boss portion 1j repeatedly elastically deforms and returns elastically multiple times (in this embodiment, twice). The repetition of elastic deformation and elastic return of the elastic arm portion 5e is transmitted to the operator as a click feeling, and the operator completes the turning operation by feeling the click feeling, and the air outlet 9 is closed. Can be easily recognized. In other words, the operator can easily recognize that the air outlet 9 is not yet closed while the user does not feel a click.

  Further, when the horizontal fin 5 automatically starts to rotate in the closing direction due to the strong blowing air pressure, the elastic arm portion 5e is moved to the boss portion via the connecting means (the pin 5c and the vertical rod 8) by the rotation of the horizontal fin 5. 1j is engaged, but the elastic arm portion 5e cannot be rotated any more by one protrusion 1k of the boss portion 1j. For this reason, the automatic rotation of the horizontal fin 5 is stopped, and the air outlet 9 is not closed. Moreover, since the rotation stop position of the horizontal fin 5 is before the whistling sound is generated, no whistling sound is generated.

  In the above embodiment, the fin shut register of the type in which the air outlet 9 is closed by the horizontal fin 5 is shown, but the present invention is for the type in which the air outlet is closed by the vertical fin 2. Needless to say, is also applicable. Moreover, the deformation | transformation provision part is not limited to the boss | hub part 1j, What is necessary is just to be able to perform the effect | action similar to the boss | hub part 1j.
