Abstract

An air conditioning register is provided that includes a case, a downstream fin, a specific upstream fin extending in a direction perpendicular to the downstream fin, and an operation knob. The specific upstream fin includes a fin main body pivotally supported by the case via an upstream fin shaft and a transmission body pivotally supported by the case via a pivot located further upstream than the upstream fin shaft. The fin main body and the transmission body are coupled to each other. The operation knob is mounted slidably on the downstream fin and includes a pair of fork portions sandwiching a transmission shaft portion of the transmission body therebetween. When the operation knob is operated to slide and thereby the transmission shaft portion is moved, the fin main body of the specific upstream fin is tilted.

First claim

The invention claimed is:

1. An air conditioning register comprising:
a case having a ventilation passage for air conditioning air;
a downstream fin pivotally supported by the case via a downstream fin shaft;
a group of upstream fins including a specific upstream fin and at least one normal upstream fin, wherein each upstream fin is pivotally supported by the case via an upstream fin shaft, the specific upstream fin and the normal upstream fin are located upstream of the downstream fin, extend in a direction perpendicular to the downstream fin, and are coupled to each other, and wherein the specific upstream fin has a transmission shaft portion extending parallel with the upstream fin shafts; and
an operation knob mounted on the downstream fin in a manner slidable in the axial direction of the downstream fin shaft and having a fork portion sandwiching therebetween the transmission shaft portion of the specific upstream fin, the fork portion being configured to move the transmission shaft portion according to sliding of the operation knob, wherein
the normal upstream fin and the specific upstream fin are pivotal to selectively open and close the ventilation passage,
the specific upstream fin is dividable into a fin main body having the upstream fin shaft and a transmission body having the transmission shaft portion and coupled to the fin main body,
the transmission body includes a pair of pivots arranged to be displaced toward the upstream side from the upstream fin shaft of the fin main body,
the transmission body is pivotally supported by the case via the pivots,
the transmission body includes a pair of tilt plate portions sandwiching the fin main body therebetween in the axial direction of the upstream fin shafts,
the transmission shaft portion is bridged between the pair of tilt plate portions,
the pair of pivots extend from the respective tilt plate portions, and
the tilt plate portions are each formed with a cut-out portion.

2. The air conditioning register according to claim 1 , wherein
one of the fin main body and the transmission body has an engaging portion and the other has an receiving portion, and
the engaging portion is arranged to be engaged with the receiving portion so that the fin main body is coupled to the transmission body.

3. The air conditioning register according to claim 2 , wherein
the engaging portion includes an engageable protrusion, and
the receiving portion includes a hole or a recess.

4. The air conditioning register according to claim 3 , wherein
the receiving portion includes an elongated hole, and
the engaging portion includes an engageable protrusion to be engaged with the elongated hole to be movable relative to the elongated hole.

5. An air conditioning register comprising:
a case having a ventilation passage for air conditioning air,
a downstream fin pivotally supported by the case via a downstream fin shaft,
a group of upstream fins including a specific upstream fin and at least one normal upstream fin, the specific upstream fin and the normal upstream fin being coupled to each other, each upstream fin being pivotally supported by the case by an upstream fin shaft, and the specific upstream fin having a transmission shaft portion extending parallel with the upstream fin shafts, both of the specific upstream fin and the normal upstream fin being located upstream of the downstream fin and extending in a direction perpendicular to the downstream fin, and the specific upstream fin having a transmission shaft portion extending parallel with the upstream fin shafts, and
an operation knob being slidably mounted on the downstream fin and slidably moving in the axial direction of the downstream fin shaft, the operation knob having a fork portion sandwiching therebetween the transmission shaft portion of the specific upstream fin, the fork portion being connected to the transmission shaft portion and moving the transmission shaft relative to sliding of the operation knob, wherein
the normal upstream fin and the specific upstream fin pivot about the upstream fin shafts to selectively open and close the ventilation passage,
the specific upstream fin includes a fin main body coupled to a transmission body, the fin main body having the upstream fin shaft, and the transmission body having the transmission shaft portion,
the transmission body includes a pair of tilt plate portions sandwiching the fin main body therebetween in the axial direction of the upstream fin shafts, the transmission shall portion of the transmission body bridging the pair of tilt plate portions,
the transmission body includes a pair of pivots arranged upstream from the upstream fin shaft of the fin main body, the pair of pivots respectively extending from opposing ends of the tilt plate portions of the transmission body into corresponding holes of the case and pivotally supporting the transmission body, and
the tilt plate portions are each formed with a cut-out portion and the upstream fin shafts are located movably in the cut-out portions.

6. The air conditioning register according to claim 5 , wherein one of the fin main body and the transmission body has an engaging portion and the other has a receiving portion, and the engaging portion engages with the receiving portion and couples the fin main body to the transmission body.

7. The air conditioning register according to claim 6 , wherein the engaging portion includes an engageable protrusion, and the receiving portion includes a hole or a recess.

8. The air conditioning register according to claim 7 , wherein the receiving portion includes an elongated hole, and the engaging portion includes an engageable protrusion that engages the elongated hole and moves relative to the elongated hole.
