Abstract

On a centerline parallel to an air blowing direction inside a retainer, a ball joint with a ball is disposed. On a turning louver, a central axial support portion from which axial support portions are projected radially is disposed at the center of a cylindrical frame. The central axial support portion is attached tiltably and turnably by fitting a ball hole provided at the center with the ball. Inside the cylindrical frame, movable fins are axially supported turnably at substantially even intervals by pivots in radial directions, and the inner-side portions of each movable fin are axially supported by each axial support portion. To the front surface side center of the central axial support portion, an operation portion is fitted turnably around the centerline of the turning louver, and the operation portion is linked to the inner-side portions of each movable fin via a bevel gear mechanism.

First claim

The invention claimed is:

1. A register comprising:
a turning louver turnable with a cylindrical frame disposed inside a cylindrical retainer, and a plurality of movable fins including five movable fins axially supported on the turning louver radially from a centerline parallel to an air blowing direction turnably by radial pivots inside the cylindrical frame, wherein
on the centerline parallel to the air blowing direction inside the retainer, a ball joint with a ball is disposed, the ball is provided on a tip end of a shaft portion attached at a center of a support frame provided on a rear portion in the retainer, and the shaft portion and a ball joint support portion extend axially from the support frame
on the turning louver, a central axial support portion with a plurality of axial support portions including five axial support portions projected radially is disposed at a center of the cylindrical frame, and the central axial support portion is attached tiltably and turnably by fitting a ball hole provided at the center with the ball,
the five movable fins are axially supported at substantially even intervals inside the cylindrical frame so as to be turnable by the pivots in radial directions, and inner-side portions of the five movable fins are axially supported by the five axial support portions of the central axial support portion,
the five axial support portions are provided at even intervals to project radially from the central axial support portion of the turning louver, and the five movable fins are disposed at even intervals inside the cylindrical frame of the turning louver and configured so as to close an inside of the cylindrical frame when the five movable fins turn until they become substantially parallel to a cross section of the cylindrical frame,
an operation portion that is disposed in front of the central axial support portion is fitted turnably around the centerline of the turning louver, and the operation portion is linked to each of the five movable fins via a bevel gear mechanism, and
according to a turning operation of the operation portion around the centerline, the five movable fins turn around the five axial support portions of the central axial support portion via the bevel gear mechanism, and when the operation portion is moved in a radial direction of the cylindrical frame, the turning louver tilts around the ball in a state where the cylindrical frame and a retainer inner surface are not in contact with each other and the turning louver is supported by the ball joint.

2. The register according to claim 1 , wherein a cup-shaped load applying member is interposed between the ball of the ball joint and the ball hole of the central axial support portion.

3. The register according to claim 1 , wherein the bevel gear mechanism is configured so that a bevel gear portion of a drive side is joined to the operation portion and axially supported turnably by a center shaft projected from the center of the central axial support portion, and bevel gear pieces of a driven side are molded integrally with the five movable fins at a radially inner side of the five movable fins, and the bevel gear portion of the drive side and each of the bevel gear pieces of the driven side mesh with each other.

4. The register according to claim 1 , wherein the cylindrical frame of the turning louver is formed by fitting a front cylindrical frame and a rear cylindrical frame, and along the cross section of the cylindrical frame, a lattice portion is provided, and on a front surface of the lattice portion, the operation portion is supported turnably, and a center portion of the operation portion is joined to the bevel gear mechanism.

5. The register according to claim 4 , wherein the pivots are projected outward from the five movable fins of the turning louver, and the pivots are sandwiched and supported turnably between the front cylindrical frame and the rear cylindrical frame.

6. The register according to claim 1 , wherein inside the retainer, the cylindrical frame of the turning louver is disposed turnably by leaving a gap between an outer peripheral surface of the cylindrical frame and an inner peripheral surface of the retainer, and in this state, a bezel is fitted to a front portion of the retainer.
