Description

  The present invention relates to an air-conditioning register that adjusts the direction of air-conditioning air sent from an air-conditioning apparatus and blown into a room.

  In an instrument panel or the like of a vehicle, an air conditioning register is provided at an outlet of air for air conditioning (hot air or cold air) sent from an air conditioner. For design reasons, a type called a round register may be used as the air conditioning register. For example, an air-conditioning register (round register) disclosed in Patent Document 1 includes a retainer, a barrel, and an elastic member as main components. The retainer includes an outer cylinder portion having a flow path for air conditioning air, and an inner cylinder portion accommodated coaxially in the outer cylinder portion. The inner cylinder part is supported by the outer cylinder part so as to be able to rotate around both central axes of the outer cylinder part and the inner cylinder part. The barrel has a plurality of blades in the inner cylinder portion for changing the air direction of the air-conditioning air blown from the retainer, and is rotatably supported by the inner cylinder portion by a shaft. The elastic member is interposed between the shaft and the inner cylinder portion, and gives sliding resistance to the shaft by being in elastic contact with the shaft.

  According to the above type of air-conditioning register (round register), the inner cylinder part is rotated through the barrel with respect to the outer cylinder part, and the barrel is rotated with respect to the inner cylinder part. The direction can be arbitrarily set, and the air direction of the air-conditioning air blown from the retainer can be adjusted.

  Further, the air conditioning register (round register) is provided with a moderation portion that gives a moderation feeling to the turning operation of the inner cylinder portion with respect to the outer cylinder portion. In Patent Document 1, the annular inner wall portion of the inner cylindrical portion is provided with a wave-like portion formed by continuously forming irregularities in the circumferential direction. On the other hand, the bottomed cylinder part provided in the outer cylinder part is provided with a hard ball and a spring for urging the hard ball toward the waved part. Therefore, when the inner cylinder portion is rotated about the central axis with respect to the outer cylinder portion through the barrel, the spring is expanded and contracted according to the unevenness of the wavy portion, and the position of the hard sphere in the wavy portion changes. By changing the operation load along with the expansion and contraction of the spring, a feeling of moderation is imparted to the rotation operation of the inner cylinder portion, and the operation feeling is improved.

  However, in the air-conditioning register (round register) described in Patent Document 1, a hard ball and a spring are added separately from the main components in order to give a moderation feeling to the turning operation of the inner cylinder portion. Therefore, the number of parts of the entire air conditioning register increases. In addition, a process of assembling the hard ball and the spring into the bottomed cylindrical portion of the outer cylindrical portion is required, and there is a problem that the man-hour for assembling the air-conditioning register increases accordingly.

  The present invention has been made in view of such circumstances, and an object thereof is to provide an air-conditioning register that can reduce the number of parts and the number of assembly steps.

In order to achieve the above object, the invention according to claim 1 includes an outer cylinder part having a flow path for air conditioning air, and an inner cylinder part accommodated coaxially in the outer cylinder part.

<Barrel 40>
As shown in FIGS. 1 and 3, the barrel 40 includes a plurality of (three in the present embodiment) blades 41 to 43 arranged at regular intervals so as to be parallel to each other. Each of the blades 41 to 43 is for changing the air direction of the air-conditioning air A blown from the air outlet 13 of the outer cylinder portion 11, and is formed in a disk shape. The central blade 42 in the arrangement direction has a larger diameter than the blades 41 and 43 on both sides. As shown in FIG. 4, when each of the blades 41 to 43 is parallel to at least the central axes L1 and L2, the flow path of the air-conditioning air A in the outer cylinder portion 11 is opened, and the blade A part of the downstream side of 41 to 43 protrudes from the air outlet 13 of the outer cylinder part 11.

  As shown in FIGS. 3 and 7, the plurality of blades 41 to 43 are connected by a pair of connecting portions 44 and 45 each having an arc shape. A shaft 46 protrudes radially outward of the blade 42 (downward in FIG. 7) from the connecting portion 44, and a shaft 47 extends radially outward from the connecting portion 45 (opposite direction to the shaft 46: FIG. 7). Projecting upward).

  One shaft 46 (downward in FIG. 7) has a round bar shape, and is rotatably engaged (supported) with the support hole 26 of the inner cylinder portion 21. The other shaft 47 (above each of FIGS. 3 and 7) has a substantially circular tube shape with an open end, and rotates into the support hole 27 of the inner cylinder portion 21 via an elastic member 50 described later.

<Elastic member 50>
The elastic member 50 is interposed between the shaft 47 and the inner cylinder portion 21, and is used to give sliding resistance to the shaft 47 by being in elastic contact with the shaft 47.

  The elastic member 50 is formed of a thermoplastic elastomer (TPE: Thermo Plastic Elastomer). Thermoplastic elastomers are polymeric materials that are plasticized (flowable) at high temperatures, can be processed like plastics, and exhibit the properties of rubber elastic bodies (elastomers) at room temperature. In this embodiment, the elastic member 50 is formed of a polyester-based thermoplastic elastomer (TPEE) that has a high crystallization speed, excellent injection moldability, and good mechanical strength, chemical resistance, low-temperature flexibility, and the like. .

  As shown in FIGS. 3 and 6, the elastic member 50 has a square plate shape and includes four corner portions 51. However, the tip of each corner 51 is formed flat and not sharp. Most of the elastic member 50 is fitted into the frame portion 29. In a state of being fitted into the frame portion 29, only one corner 51 of the elastic member 50 is exposed to the air outlet 13 side (left side in FIG. 6) outside the frame portion 29 through the notch 31. .

A through hole 52 is formed at the center of the elastic member 50, and the shaft 47 of the barrel 40 is press-fitted into the through hole 52.
<Moderation part 60>
As shown in FIG. 2 and FIG. 6, the moderation portion 60 is provided in order to give a moderate feeling of moderation to the turning operation of the inner cylinder portion 21 through the barrel 40. A part of the moderation portion 60 is constituted by a wave-like portion 61 formed on the inner wall portion 17 of the outer cylinder portion 11. The wavy portion 61 is formed by continuously providing irregularities 62 in the circumferential direction of the inner wall portion 17 (around the central axis lines L1 and L2). In the present embodiment, the corrugated portion 61 is formed over the entire circumference of the inner wall portion 17. The wavy portion 61 is integrally formed with the outer cylinder portion 11 by the same resin material as that of the outer cylinder portion 11.

  The moderation part 60 is provided with the engaging part 53 engaged with the one part unevenness | corrugation 62 of this wavy part 61 other than the said wavy part 61. FIG. The engaging portion 53 is constituted by a part of the elastic member 50. In the present embodiment, one corner 51 exposed from the frame 29 to the air outlet 13 through the notch 31 functions as the engaging portion 53. The moderation portion 60 imparts a sense of moderation by elastic deformation and elastic recovery when the engaging portion 53 moves on the wave-like portion 61 as the inner cylinder portion 21 rotates.

  The air conditioning register is configured as described above. In manufacturing the air conditioning register, as shown in FIGS. 2 and 3, first, the above-described components (the outer cylindrical portion 11 and the inner cylindrical portion 21 of the retainer 10, the barrel 40, the elastic member 50, the corrugated portion 61, etc.). ) Are formed.

  Next, the barrel 40 is assembled to the inner cylinder portion 21. In this assembly, the barrel 40 is accommodated in the peripheral wall portion 22 of the inner cylinder portion 21, the one shaft 46 is fitted into the support hole 26, and the other shaft 47 is inserted into the inner shaft 47 via the elastic member 50. Supporting to the cylinder part 21 is performed.

  When the shaft 47 is supported on the inner cylinder portion 21 via the elastic member 50, the shaft 47 is positioned substantially at the center of the square cylindrical frame portion 29. In this state, as shown in FIG. 6, many portions of the elastic member 50 are inserted into the frame portion 29. In the process of this insertion, the shaft 47 is press-fitted into the through hole 52 of the elastic member 50, and a part (one corner 51) of the elastic member 50 passes through the notch 31 and the frame portion 29 (attached portion 28). Exposed outside. By inserting many portions of the elastic member 50 into the frame portion 29, the elastic member 50 is attached to the adherend portion 28. In this state, one shaft 46 is rotatably supported by the inner cylinder portion 21 without the elastic member 50, and the other shaft 47 is rotatably supported by the inner cylinder portion 21 via the elastic member 50. .

  Here, the elastic member 50 of the present embodiment having a square plate shape has a plurality (four) of corners 51. For this reason, one of the plurality of corner portions 51 is exposed to the air outlet 13 side through the notch 31 by inserting many portions of the elastic member 50 into the frame portion 29 as described above.

  Subsequently, the inner cylinder part 21 supported by the barrel 40 as described above is inserted into the outer cylinder part 11. With this insertion, the flange portion 24 of the inner cylinder portion 21 approaches the annular inner wall portion 17 of the outer cylinder portion 11. In addition, each claw portion 25 of the inner cylinder portion 21 approaches the annular protrusion 14 of the outer cylinder portion 11.

  In the approaching process, the corner 51 exposed from the notch 31 of the elastic member 50 abuts on the corrugated portion 61 and engages with the irregularities 62. Thus, when the inner cylinder part 21 is accommodated in the outer cylinder part 11 coaxially, the exposed part (one corner part 51) of the elastic member 50 from the adherent part 28 is uneven. By engaging with 62, it functions as the engaging portion 53.

  Further, the claw portions 25 come into contact with the annular protrusion 14 before and after the contact (engagement). When the inner cylinder portion 21 is further inserted into the outer cylinder portion 11 from this state, the engaging portion 53 of the elastic member 50 is slightly elastically deformed. At the same time, the claw portions 25 are elastically deformed away from the central axes L1 and L2, thereby overcoming the annular protrusion 14 and engaging with the outer cylinder portion 11 (see FIGS. 5 and 7).

  As described above, when the elastic member 50 is mounted on the adherend portion 28 of the inner cylinder portion 21 and the inner cylinder portion 21 is accommodated coaxially in the outer cylinder portion 11, the inner cylinder is interposed via the elastic member 50. An operation of rotatably supporting the shaft 47 on the portion 21 and an operation of engaging the engaging portion 53 of the elastic member 50 with the unevenness 62 of the wave-like portion 61 are performed.

Next, the operation of the air-conditioning register of the present embodiment manufactured as described above will be described.
In this air conditioning register, the elastic member 50 interposed between the shaft 47 of the barrel 40 and the inner cylinder portion 21 of the retainer 10 is in elastic contact with the shaft 47 in the through hole 52. The elastic member 50 has a rectangular plate shape that is a non-disk shape and is fitted into the rectangular tube-shaped frame portion 29, and therefore does not rotate within the frame portion 29. By this elastic contact, a sliding resistance is applied to the shaft 47 and the rotation of the barrel 40 relative to the inner cylinder portion 21 is restricted. Further, a part of the elastic member 50 is engaged as an engaging portion 53 with an uneven portion 62 of a wave-like portion 61 provided on the inner wall portion 17 of the outer cylinder portion 11. By this engagement, the rotation of the inner cylinder part 21 with respect to the outer cylinder part 11 is restricted.

  The air-conditioning air A sent from the air conditioner blows out from the air outlet 13 of the outer cylinder portion 11 after passing through the retainer 10 of the air-conditioning register. The air-conditioning air A flows along the blades 41 to 43 of the barrel 40 when passing through the retainer 10, whereby the blowing direction from the air outlet 13 is determined.

  Here, the inner cylinder portion 21 on which the barrel 40 is supported is rotatable with respect to the outer cylinder portion 11 about the central axes L1 and L2 together with the barrel 40. Further, the barrel 40 is rotatable with respect to the inner cylinder portion 21 with the shafts 46 and 47 as fulcrums. Since the extending direction of the central axes L1 and L2 and the extending direction of the axis L3 (see FIGS. 4 and 5) passing through both the shafts 46 and 47 of the barrel 40 are orthogonal to each other, the barrel 40 is connected to the outer cylinder portion 11. On the other hand, it can be rotated about two axes. Therefore, while rotating the inner cylinder part 21 with respect to the outer cylinder part 11 through the barrel 40, and rotating the barrel 40 with respect to the inner cylinder part 21, the air-conditioning air A with respect to the central axes L1 and L2 is obtained. By adjusting the inclination of the blades 41 to 43 with respect to the flow direction, the air-conditioning air A can be blown out from the air outlet 13 in an arbitrary direction.

  Incidentally, in FIG. 4, the blades 41 to 43 are made parallel to both the central axes L1 and L2, the flow path of the air conditioning air A in the outer cylinder portion 11 is opened, and the air conditioning air A passes from the air outlet 13. The case where it blows straight to the passenger side is shown.

  As shown in FIG. 7, when the barrel 40 is rotated so that the blades 41 to 43 are orthogonal to the central axes L1 and L2, the blades 41 to 43 and the outer tube portion 11 or the inner tube portion 21 are rotated. The air-conditioning air A flow path in the outer cylinder portion 11 is blocked by the blades 41 to 43, and the air-conditioning air A is not blown out from the air outlet 13. It is done.

  The rotation operation with respect to the inner cylinder portion 21 of the barrel 40 around the shafts 46 and 47 is performed against the sliding resistance applied from the elastic member 50 to the shaft 47. Due to this sliding resistance, a load (operation load) when the barrel 40 is rotated is created.

  Further, when the inner cylinder portion 21 is rotated through the barrel 40 with respect to the outer cylinder portion 11, the engaging portion 53 of the elastic member 50 engaged with the unevenness 62 of the waved portion 61 is engaged with another unevenness 62. This is done by moving to a matching position. The above-described movement of the engaging portion 53 is performed by elastically deforming and elastically restoring the engaging portion 53 in accordance with the shape of the engaging unevenness 62. Along with the elastic deformation and elastic recovery of the engagement portion 53, the force (operation load) required for the rotation operation when the engagement portion 53 changes the engagement position in the waved portion 61 changes, and the rotation of the inner cylinder portion 21 changes. A sense of moderation is added to the dynamic operation.

  Thus, in this embodiment, in addition to the function of creating an operation load when the barrel 40 is rotated, the elastic member 50 exhibits a function of imparting a sense of moderation to the rotation operation of the inner cylinder portion 21. For this reason, unlike the case of imparting a sense of moderation by pressing a hard ball against a wave-like portion with a spring (Patent Document 1), a step of assembling the spring and the hard ball becomes unnecessary.

According to the embodiment described in detail above, the following effects can be obtained.
(1) As an air-conditioning register, a register including the retainer 10, the barrel 40, the elastic member 50, and the moderation portion 60 is targeted (FIG. 3). In the retainer 10, the inner cylinder part 21 accommodated coaxially in the outer cylinder part 11 is supported by the outer cylinder part 11 so that it can rotate centering on those center axis lines L1 and L2. The barrel 40 having a plurality of blades 41 to 43 in the inner cylinder portion 21 is supported by the shafts 46 and 47 so as to be rotatable. The elastic member 50 is interposed between the shaft 47 and the inner cylinder portion 21, and a sliding resistance is applied to the shaft 47 by elastic contact with the shaft 47 of the elastic member 50 (FIG. 5). As the moderation part 60, a wave-like part 61 formed by continuously forming irregularities 62 in the circumferential direction of the annular inner wall part 17 in the outer cylinder part 11, and a part of the elastic member 50 are engaged with the wave-like part 61. And an engaging portion 53 (FIGS. 2 and 6). And when the engaging part 53 moves on the waved part 61 with the rotation of the inner cylinder part 21, the engaging part 53 is elastically deformed and elastically restored so that the inner cylinder part 21 can be rotated. A moderation is given. In this manner, the elastic member 50 is allowed to exhibit the function of creating an operation load when the barrel 40 is rotated and the function of imparting a moderation feeling to the rotation operation of the inner cylinder portion 21.

  Therefore, the number of parts of the air-conditioning register can be reduced and the number of assembling steps can be reduced as compared with the one that imparts a feeling of moderation by pressing the hard sphere against the waved portion by a spring (Patent Document 1).

(2) The inner wall portion 17 of the outer cylindrical portion 11 is formed at a location approaching the elastic member 50 in a state where the inner cylindrical portion 21 is coaxially accommodated in the outer cylindrical portion 11 (FIGS. 5 and 5). 7).

  (4) The adherend portion 28 is constituted by a cylindrical frame portion 29 having a notch 31 in part. Then, with a part of the elastic member 50 being exposed from the notch 31, many portions of the elastic member 50 are fitted into the frame portion 29 so that the elastic member 50 is attached to the adherend portion 28. (FIGS. 5 and 6).

  Therefore, only by performing the work of inserting many portions of the elastic member 50 into the cylindrical frame portion 29, a part of the elastic member 50 is exposed to the outside of the frame portion 29 (attached portion 28) through the notch 31. It can be exposed and function as the engaging portion 53 engaged with the wave-like portion 61.

  (5) In the present embodiment in which the elastic member 50 having a rectangular plate shape is used, one of the corner portions 51 of the elastic member 50 is engaged with the corrugated portion 61 as the engaging portion 53. (Fig. 6).

  As described above, since one of the plurality of corner portions 51 is used as the engaging portion 53 to be engaged with the corrugated portion 61, it is not necessary to provide the engaging portion 53 specially on the elastic member 50. . The conventional elastic member 50 can be used as it is.

  Further, since the four corner portions 51 have the same shape, any of the corner portions 51 can be exposed from the notch 31 to be the engaging portion 53. Accordingly, the elastic member 50 can be positioned more easily with respect to the frame portion 29 than in the case where a portion exposed from the notch 31 is provided at only one portion of the elastic member 50, and many portions of the elastic member 50 are fitted into the frame portion 29. It is easy to attach (attached to the adherend portion 28).

  Further, if the engagement portion 53 wears out due to the use of the moderation portion 60 and the feeling of moderation is weakened, the elastic member 50 is temporarily removed from the frame portion 29 and the corner that is not yet used as the engagement portion 53 is used. The part 51 can be exposed from the frame part 29 and can be engaged with the unevenness 62 of the waved part 61 as a new engaging part 53.
