Abstract

The front movable louver ( 3 ) includes one central fin ( 7 ) and an upper auxiliary fin ( 8 ) and a lower auxiliary fin ( 9 ) storable in storing recesses ( 6 a, 6 b ) inside an air outlet. The central fin ( 7 ) is axially supported turnably by pivots ( 7 a ) provided on both sides of the vicinity of the downstream side end portion. The upper auxiliary fin ( 8 ) and the lower auxiliary fin ( 9 ) are axially supported turnably so as to stick out their downstream side end portions to the passage ( 5 ) side by pivots provided on both sides of the vicinities of the upstream side end portions. A cam link mechanism ( 10 ) turns the upper auxiliary fin ( 8 ) and the lower auxiliary fin ( 9 ) so that the upper auxiliary fin ( 8 ) sticks out its downstream side end portion to the passage side, and the lower auxiliary fin ( 9 ) becomes parallel to and approaches the central fin ( 7 ) so that these fins function as one large fin when the central fin ( 7 ) is turned in the short-side direction of the air outlet ( 15 ).

First claim

The invention claimed is:

1. A register comprising:
a narrow and long rectangular-shaped air outlet, with a front movable louver that is provided with a plurality of front fins turnably and disposed inside the air outlet, wherein
the front movable louver is configured so that while one central fin is axially supported at substantially a center of an inside of the air outlet turnably around an axis parallel to a longitudinal direction of the air outlet, a pair of auxiliary fins are axially supported in such a manner that the auxiliary fins are storable in storing recesses provided on wall surfaces on both sides inside the air outlet and turnable around axes parallel to the axis of the central fin while being parallel to the central fin,
the central fin is axially supported turnably by pivots provided on both sides of a vicinity of a downstream side end portion, and the pair of auxiliary fins are axially supported turnably so as to stick out their downstream side end portions to a passage side by pivots provided on both sides of vicinities of upstream side end portions,
a cam link mechanism is provided which turns the auxiliary fins so that when the central fin is turned in a short-side direction of the air outlet, one of the auxiliary fins sticks out its downstream side end portion to the passage side, and the other auxiliary fin becomes parallel to and approaches the central fin with the other auxiliary fin and the central fin being in line so that these fins function as one fin, and
the cam link mechanism is configured so that a plurality of cam grooves are provided in a cam plate axially supported rotatably, and in the cam grooves, an engagement pin of a link joined to one of the pivots of the central fin is engaged and engagement pins of links joined to the pivots of the pair of auxiliary fins are engaged.

2. The register according to claim 1 , wherein in the cam plate of the cam link mechanism, two cam grooves in which the engagement pins of the links of the pair of auxiliary fins engage are formed into symmetrical shapes, and a rotary shaft of the cam plate is disposed on an upstream side further than tip end positions of the auxiliary fins.

3. A register comprising:
a narrow and long air outlet that is long in a horizontal direction and short in an up-down vertical direction, with a front movable louver disposed along the horizontal direction in an inner front portion of the air outlet, where the air outlet is formed to incline so as to retract its upper portion to an upstream side and project its lower portion, to a downstream side, wherein
the front movable louver is configured so that while one central horizontal fin is axially supported in the horizontal direction turnably at substantially an up-down center of an inside the air outlet, an upper auxiliary horizontal fin is axially supported so as to be storable and turnable in the horizontal direction in a storing recess provided on an upper wall surface inside the air outlet, and a lower auxiliary horizontal fin is axially supported so as to be storable and turnable in the horizontal direction in a storing recess provided on a lower wall surface inside the air outlet,
the central horizontal fin is axially supported turnably by pivots provided on both sides of a vicinity of a downstream end portion, and the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are axially supported turnably so as to stick out their downstream side end portions to a passage side by pivots provided on both sides of vicinities of upstream end portions,
a cam link mechanism is provided so as to, when the central horizontal fin is turned up or down, turn the upper auxiliary horizontal fin and the lower auxiliary horizontal fin in such a manner that the upper auxiliary horizontal fin or the lower auxiliary horizontal fin sticks out its downstream side end portion to the passage side, and the lower auxiliary horizontal fin or the upper auxiliary horizontal fin becomes parallel to and approaches the central horizontal fin with the lower auxiliary horizontal fin or the upper auxiliary horizontal fin and the central horizontal fin being in line so that these fins function as one fin, and
the cam link mechanism is configured so that a plurality of cam grooves are formed in a cam plate axially supported rotatably, and in the cam grooves, an engagement pin of a link joined to one of the pivots of the central horizontal fin and engagement pins of links joined to the pivots of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are engaged.

4. The register according to claim 3 , wherein in the cam plate of the cam link mechanism, two cam grooves in which the engagement pins of the links of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin engage are formed into symmetrical shapes, and a rotary shaft of the cam plate is disposed on the upstream side further than tip end positions of the upper auxiliary horizontal fin and the lower auxiliary horizontal fin.

5. A register comprising:
a narrow and long air outlet that is long in an up-down vertical direction and short in a horizontal direction, with a front movable louver disposed along the up-down vertical direction in an inner front portion of the air outlet, where the air outlet is inclined so as to retract one side portion to an upstream side and project another side portion to a downstream side, wherein
the front movable louver is configured so that while one central vertical fin is axially supported in the up-down vertical direction turnably at substantially a right-left center of a retraction side inside the air outlet, a retraction-side auxiliary vertical fin is axially supported so as to be storable and turnable in the up-down vertical direction in a storing recess provided on a side wall surface on the retraction side inside the air outlet, and a projection-side auxiliary vertical fin is axially supported so as to be storable and turnable in the up-down vertical direction in a storing recess provided on a side wall surface on a projection side inside the air outlet, the central vertical fin is axially supported turnably by pivots provided on both sides of a vicinity of a downstream side end portion, and the retraction-side auxiliary vertical fin and the projection-side auxiliary vertical fin are axially supported turnably so as to stick out their downstream side end portions to a passage side by pivots provided on both sides of vicinities of upstream side end portions,
a cam link mechanism is provided so as to when the central vertical fin is turned right or left, turn the retraction-side auxiliary vertical fin and the projection-side auxiliary vertical fin in such a manner that the retraction-side auxiliary vertical fin and the projection-side auxiliary vertical fin stick out their downstream side end portions to the passage side, and the projection-side auxiliary vertical fin or the retraction-side auxiliary vertical fin becomes parallel to and approaches the central vertical fin with the projection-side auxiliary vertical fin or the retraction-side auxiliary vertical fin and the central vertical fin being in line so that these fins function as one fin, and
