Abstract

An air conditioning register includes a downstream fin, primary upstream fins, a secondary upstream fin, and an operation knob slidably attached onto the downstream fin. The operation knob sandwiches a shaft of the secondary upstream fin. The air conditioning register has a link mechanism that includes arms and a coupling rod. The arms extend from pivots of the primary and secondary upstream fins in a direction orthogonal to the pivots, and have a pin at the tip of the arms. The coupling rod couples the respective pins. The distance between the pivot and the pin in the arm of the secondary upstream fin is longer than the distance between the pivot and the pin in the arm of each primary upstream fin. The coupling rod includes coupling portions, each of which couples the pins of an adjacent pair of the arms. Adjacent coupling portions are pivotally coupled.

First claim

The invention claimed is:

1. An air conditioning register to adjust a flow direction of air for air conditioning, the register comprising:
a case having a ventilation passage for the air;
at least one plate-shaped downstream fin that has a downstream fin pivot and is pivotally supported by the case via the downstream fin pivot;
a plurality of primary upstream fins that are located upstream of the downstream fin in the ventilation passage, wherein each of the primary upstream fins extends in a direction orthogonal to the downstream fin, includes a primary upstream fin pivot, and is pivotally supported by the case via the primary upstream fin pivot;
a secondary upstream fin that is located upstream of the downstream fin in the ventilation passage, wherein the secondary upstream fin includes a pivot, extends in the direction orthogonal to the downstream fin, is pivotally supported by the case via the secondary upstream fin pivot, and has a shaft extending along the secondary upstream fin pivot of the secondary upstream fin;
an operation knob that is slidably attached onto the at least one downstream fin and has a pair of fork portions sandwiching the shaft of the secondary upstream fin; and
a link mechanism that couples the primary upstream fins and the secondary upstream fin to each other, wherein
the link mechanism includes a plurality of arms and a coupling rod, wherein each arm extends from one of the primary upstream fin pivot of the primary upstream fins and the secondary upstream fin in a direction orthogonal to the secondary upstream fin pivot, wherein each arm has a pin formed at a position offset from the primary upstream fin pivot or secondary upstream fin pivot,
the primary upstream fins and the secondary upstream fin are capable of adjusting the flow direction of the air and selectively opening and closing the ventilation passage by tilting,
a distance between the secondary upstream fin pivot and the pin in the arm of the secondary upstream fin is set to be longer than a distance between the primary upstream fin pivot and the pin in the arm of each primary upstream fin,
the coupling rod couples each arm together via the pins, wherein the coupling rod includes a plurality of coupling portions each of which is coupled to the pins in the arms of each adjacent pair of the arms, and
adjacent coupling portions are pivotally coupled via the pin in the arm.

2. The air conditioning register according to claim 1 , wherein the secondary upstream fin includes a main portion, and the secondary upstream fin pivot is located at a most upstream part of the main portion.

3. The air conditioning register according to claim 2 , wherein a hollow is formed in the main portion of the secondary upstream fin between the secondary upstream fin pivot and the shaft, the hollow formed to cooperatively slide the operation knob along the shaft of the secondary upstream fin.

4. The air conditioning register according to claim 2 , wherein the secondary upstream fin is located between a pair of the primary upstream fins, and one of the pair of the primary upstream fins has an integrally formed auxiliary fin, which is located upstream of the secondary upstream fin pivot and the integrally formed auxiliary fin tilts with the primary upstream fin.

5. The air conditioning register according to claim 1 , wherein adjacent coupling portions are each rotationally engaged with one of the pins in the arms at different positions in a longitudinal direction of the pin and are pivotally coupled to each other via a common pin.

6. The air conditioning register according to claim 1 , wherein in the coupling rod, adjacent coupling portions are integrally formed via a hinge portion and are rotationally engaged at the hinge portion with the pin, and adjacent coupling portions are pivotally coupled to each other at the hinge portion.
