Register

Abstract

A register has a narrow and long air outlet that is long in the longitudinal direction and short in the short-side direction, includes, but is not limited to a front movable louver that changes the wind direction in the short-side direction arranged inside the air outlet, and includes a rear movable louver that changes the wind direction in the longitudinal direction arranged upstream from the front movable louver. A back movable louver is arranged upstream from the rear movable louver in order to change the wind direction in the short-side direction. The back movable louver changes the wind direction by turning in a direction opposite to a direction in which the front movable louver is turned in the short-side direction.

1 . A register, comprising:
 a narrow and long air outlet that is long in a longitudinal direction and short in a short-side direction;   a front movable louver that changes a wind direction in said short-side direction arranged in an air passage inside of said narrow and long air outlet;   a rear movable louver that changes the wind direction in said longitudinal direction arranged upstream of said rear movable louver;   a back movable louver disposed upstream of said rear movable louver in order to change the wind direction in said short-side direction; and   a first back fin and a second back fin axially supported along both inner surfaces in said air passage, so as to be turnable via pivots that are parallel to the longitudinal direction,   wherein when the wind direction is changed in a short-side direction, said first back fin is turned in a short-side direction while the other of said second back fin is kept parallel to said air passage, and   wherein the front movable louver is turned in a direction opposite to a direction in which said back movable louver is turned in the short-side direction to change the wind direction in the short-side direction.   
     
     
         2 . The register according to  claim 1 , wherein inner recesses are formed on both inner surfaces in the air passage, and the first back fin and the second back fin are arranged so as to be storable in said inner recesses. 
     
     
         3 . A register, comprising:
 a narrow and long air outlet that is long in a longitudinal direction and short in a short-side direction;   a front movable louver that changes the wind direction in said short-side direction arranged in an air passage inside of said narrow and long air outlet;   a rear movable louver that changes the wind direction in said longitudinal direction arranged upstream of said rear movable louver,   a back movable louver disposed upstream of said rear movable louver in order to change the wind direction in said short-side direction; and   a back fin is axially supported in said air passage so as to be turnable via pivots that are parallel to a longitudinal direction,   wherein when the wind direction is changed in a short-side direction, said one back fin is turned in a short-side direction, and the front movable louver is turned in a direction opposite to a direction in which said back movable louver is turned in the short-side direction to change the wind direction in the short-side direction.   
     
     
         4 . The register according to  claim 1 , further comprising at least two front fins of the front movable louver are axially supported so as to be turnable via pivots that are parallel to the longitudinal direction, all of said front fins turn in conjunction are oriented in a direction to change the wind direction in a short-side direction. 
     
     
         5 . A register, comprising:
 a narrow and long air outlet that is long in a longitudinal direction and short in a short-side direction;   chevron projections having inclined surfaces at an upstream side formed along the longitudinal direction on both inner surfaces in an air passage along the longitudinal direction near said narrow and long air outlet, and formed so as to bend an air flow of said air passage close to a center of the air outlet while blown out with the direction of said inclined surfaces of the chevron projections oriented upstream of said air passage, and   a rear movable louver arranged upstream from said chevron projections so as to change the wind direction in said longitudinal direction and   a back movable louver in said air passage and upstream from the rear movable louver having one back fin axially supported so as to be turnable via pivots along the longitudinal direction,   wherein an air flow contracted by a turn of said back fin is bent by said chevron projections in a direction opposite to that of a bend in a short-side direction by said back fin to change the wind direction in a short-side direction.   
     
     
         6 . The register according to  claim 5 , wherein the chevron projections are continuously formed with substantially the same cross-sections in the longitudinal direction of said narrow and long air outlet on both opposite inner surfaces in the air passage along the longitudinal direction near the air outlet, and surfaces at a downstream side of said chevron projections are formed in a shape opened so as to expand forward. 
     
     
         7 . The register according to  claim 1 , further comprising at least two front fins of the front movable louver axially supported so as to be turnable via pivots that are parallel to the longitudinal direction, all of said front fins turn in conjunction are oriented in a direction to change the wind direction in a short-side direction.
