  • Patent number: 11566814
    Abstract: Provided is a register that can more surely suppress abnormal noise caused by air passing through a space between a damper and a retainer. An inner wall of an upper side wall of the retainer is formed with a plurality of rib parts provided on a downstream side relative to an outer periphery on the downstream side of a plate member in a closed state of a damper. The plurality of rib parts is arranged in a direction parallel to a turning axis of the damper, and adjacent rib parts are formed into different shapes. A soft seal member is provided with a plurality of protrusion parts on an upper surface of the outer periphery on the downstream side of the plate member.

  • Patent number: 11351844
    Abstract: A register includes an annular fin that can improve the directivity of air conditioning air while suppressing increase in the number of parts. A front fin includes an annular-shaped annular fin portion. A bezel has upstream side inclined surfaces formed on inner peripheral surfaces facing with each other in the shorter side direction (vertical direction) of an air blow outlet. The upstream side inclined surfaces incline toward a direction of approaching the annular fin portion from an upstream side toward a downstream side of an air blowing direction. An air conditioning air flowing in the air blowing direction is guided to the annular fin portion side by the upstream side inclined surfaces.

  • Publication number: 20170057327
    Abstract: A front fin of a front movable louver is axially supported immediately inside of an air outlet, and an auxiliary fin is axially supported in a recessed portion under the front fin. The front fin and the auxiliary fin are joined via a link member, and opposite side end portions at an upstream side of the auxiliary fin are axially supported via pivots. An inclined surface is provided on a distal end portion at a downstream side of the auxiliary fin. A recessed portion cover to overlay the recessed portion is attached to the recessed portion. When the front movable louver is operated so as to turn, the auxiliary fin turns so as to project its distal end portion upward through an opening in a front portion of the recessed portion cover and make the inclined surface of its distal end portion hit against an air flow flowing under the front fin.

  • Patent number: 9162551
    Abstract: A register has a narrow and long air blow outlet long in the longitudinal direction and short in the shorter-side direction, and is provided with a front movable louver along the longitudinal direction inside the air blow outlet. The front movable louver has one vertical fin having an annular fin portion at the center. The annular fin portion is formed so as to have a substantially rectangular opening in an air blowing direction in a front view, and has flat plate portions on both side portions. Upper shaft portions are provided on both end portions of the annular fin portion via upper fin portions, and lower shaft portions are provided via lower fin portions. The upper shaft portions and lower shaft portions are supported turnably on bearing portions of fixed walls.
