Abstract

Each fin shaft of auxiliary fins passes through each of upper and lower bearing parts in a first wall part. A pair of transmission shafts provided for the upper and lower fin shafts is arranged outside of the first wall part. A cam member is rotationally arranged outside of the first wall part. A fin shaft of a main fin is rotationally supported by the first wall part. The fin shaft of the main fin has an arm and a transmission shaft. The cam member has cam holes in which the transmission shafts of the upper auxiliary fin are fitted, cam holes in which the transmission shafts of the lower auxiliary fin are fitted, and a long hole in which the transmission shaft of the fin shaft of the main fin is fitted.

First claim

The invention claimed is:

1. A register for air conditioning comprising:
a cylindrical case formed of two first wall parts that are opposite each other in a first direction and two second wall parts that are opposite each other in a second direction, which is substantially orthogonal to the first direction, wherein the case has a dimension in the first direction that is larger than a dimension in the second direction;
two auxiliary fins arranged in the case near corresponding ones of the second wall parts, wherein the auxiliary fins extend in the first direction and rotate in the second direction about corresponding fin shafts;
a main fin arranged between the auxiliary fins and supported by each of the first wall parts through a fin shaft, wherein the main fin extends in the first direction and rotates in the second direction; and
an interlock mechanism to rotate each of the auxiliary fins while moving at least one of an upstream end and a downstream end of each of the auxiliary fins toward one of the second wall parts in response to rotation of the main fin,
the interlock mechanism including:
two bearing parts formed in the first wall parts near the second wall parts, wherein the bearing parts permit the fin shafts of each of the auxiliary fins to pass therethrough such that the fin shafts of each of the auxiliary fins become closer to and farther from one of the second wall parts;
two transmission shafts arranged outside of each of the first wall parts, wherein the transmission shafts are coupled to each of the fin shafts passing through the bearing parts;
a cam member rotationally arranged outside of each of the first wall parts, wherein the cam member has a fitting target in which each of the transmission shafts is fitted, the fitting target being formed of a groove part or a long hole; and
a transmission unit to rotate the cam member by transmitting rotation of the main fin to the cam member.

2. The register for air conditioning according to claim 1 , wherein
the fin shaft of the main fin penetrates through each of the first wall parts, and
the transmission unit includes:
an arm provided outside of each of the first wall parts, the arm extending from the fin shaft of the main fin in a direction orthogonal to the fin shaft of the main fin;
a transmission shaft provided in a position on the arm shifted from the fin shaft of the main fin; and
a transmission fitting target formed in the cam member, the transmission fitting target receiving the transmission shaft of the transmission unit, the transmission fitting target being formed of a groove part or a long hole.

3. The register for air conditioning according to claim 1 , wherein
the fin shaft of the main fin penetrates through each of the first wall parts, and
the transmission unit includes:
a drive gear provided outside of each of the first wall parts and fixed to the fin shaft of the main fin; and
a driven gear provided to the cam member, the driven gear forming meshing engagement with the drive gear.

4. The register for air conditioning according to claim 1 , wherein the fin shafts of each of the auxiliary fins are arranged between the center of a thickness direction of this auxiliary fin and one of the second wall parts.

5. The register for air conditioning according to claim 4 , wherein each of the bearing parts is partially formed in a boundary area between one of the second wall parts and one of the first wall parts.
