Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
303 words
A grille for air conditioning comprising: a main body portion having an opening for blowing out a wind; a plurality of reinforcing plates each said plate having a longitudinal axis, a proximal edge located at a downstream side of the wind and a distal edge located at an upstream side of the wind, said reinforcing plates being connected at each longitudinal end thereof between opposing walls of said main body portion so that said reinforcing plates are disposed in parallel spaced relation, said reinforcing plates being disposed so that the edges thereof extend in a substantially intersecting direction with a blowing direction of the wind; a plurality of flexible wind deflecting plates, each said flexible wind deflecting plate having a longitudinal axis, a proximal edge located at a downstream side of the wind and a distal edge located at an upstream side of the wind, said distal edge of each said flexible wind deflecting plate being connected to the proximal edge of a respective said reinforcing plate so that the longitudinal axis of each said flexible wind deflecting plate is substantially parallel to the longitudinal axis of said respective reinforcing plates; a plurality of front wind deflecting plates mounted to said main body so as to be disposed downstream of said flexible wind deflecting plates, each said wind deflecting plate having a longitudinal axis disposed substantially perpendicular to said longitudinal axis of said flexible deflecting plates; and an operating piece slidably supported by one of said front wind deflecting plates, said operating piece having an upstream portion and a downstream portion, said upstream portion of said operating piece having grooves defined therein, each said groove engaging a center of said downstream edge of a said flexible wind deflecting plate, the engaged portions of said flexible wind deflecting plates being movable within said grooves.

A grille for air conditioning comprising: a main body portion having an opening for blowing out a wind; a plurality of reinforcing plates each said plate having a longitudinal axis, a proximal edge located at a downstream side of the wind and a distal edge located at an upstream side of the wind, said reinforcing plates being connected at each longitudinal end thereof between opposing walls of said main body portion so that said reinforcing plates are disposed in parallel spaced relation, said reinforcing plates being disposed so that the edges thereof extend in a substantially intersecting direction with a blowing direction of the wind; a plurality of flexible wind deflecting plates, each said flexible wind deflecting plate having a longitudinal axis, a proximal edge located at a downstream side of the wind and a distal edge located at an upstream side of the wind, said distal edge of each said flexible wind deflecting plate being connected to the proximal edge of a respective said reinforcing plate so that the longitudinal axis of each said flexible wind deflecting plate is substantially parallel to the longitudinal axis of said respective reinforcing plates; a plurality of front wind deflecting plates mounted to said main body so as to be disposed downstream of said flexible wind deflecting plates, each said wind deflecting plate having a longitudinal axis disposed substantially perpendicular to said longitudinal axis of said flexible deflecting plates; and an operating piece slidably supported by one of said front wind deflecting plates, said operating piece having an upstream portion and a downstream portion, said upstream portion of said operating piece having grooves defined therein, each said groove engaging a center of said downstream edge of a said flexible wind deflecting plate, the engaged portions of said flexible wind deflecting plates being movable within said grooves.
Claim 3
Dependent Claim
35 words
A grille for air conditioning, as set forth in claim 1, wherein the front wind deflecting plates are rigid plates, which are rotatably supported at their rear ends by shafts supported by said main body.
Claim 4
Dependent Claim
79 words
A grille for air conditioning, as set forth in claim 2, wherein the flexible wind deflecting plates are formed from an elastomeric material, recessed notches are formed on the front ends of the flexible wind deflecting plates, the front end of each said notch being provided with a shaft that engages with a respective said groove in said operating piece, said shafts being inserted in the front end portions along the entire length of said flexible wind deflecting plates.
Claim 5
Dependent Claim
71 words
A grille for air conditioning, as set forth in claim 2, wherein said reinforcing plates each have a groove defined therein and the rear end portions of said flexible wind deflecting plates each having an insertion portion sized so as to be receivable in a said groove of a respective reinforcing plate so that said reinforcing plates are connected to said flexible wind deflecting plates by an insert and lock structure.
Claim 6
Dependent Claim
54 words
A grille for air conditioning, as set forth in claim 2, wherein the flexible wind deflecting plates are formed such that their cross sectional areas, taken in the direction perpendicular to the direction of the wind coming from the rear portion of said main body, become smaller toward the front portions of the plates.
Claim 7
Dependent Claim
31 words
A grille for air conditioning, as set forth in claim 5, wherein the flexible wind deflecting plates are formed such that their thickness becomes smaller toward the front of the plate.
Claim 8
Dependent Claim
32 words
A grille for air conditioning, as set forth in claim 5, wherein the flexible wind deflecting plates are formed such that their vertical length becomes smaller toward the front of the plate.
Claim 9
Dependent Claim
26 words
A grille for air conditioning, as set forth in claim 1, wherein said main body is supported inside a wind duct such that it is rotatable.
Claim 10
Dependent Claim
56 words
A grille for air conditioning, as set forth in claim 8, wherein the flexible wind deflecting plates are formed from an elastomeric material, recessed notches are formed on the front ends of the flexible wind deflecting plates, the front end portions thereof being mounted with engagement pieces that engage with said grooves in said operating piece.
Claim 11
Dependent Claim
75 words
A grille for air conditioning, as set forth in claim 8, wherein said reinforcing plates each have a groove defined therein and the rear end portions of said flexible wind deflecting plates each having an insertion portion sized so as to be receivable in a said groove of a respective reinforcing plate so that said reinforcing plates are connected to said flexible wind deflecting plates to form single units by an insert and lock structure.
Claim 12
Dependent Claim
56 words
A grille for air conditioning, as set forth in claim 8, wherein the flexible wind deflecting plates are formed such that their cross sectional areas, taken in the direction perpendicular to the direction of flow of the wind coming from the rear portion of the main body, become smaller toward the front ends of the plates.
Claim 13
Dependent Claim
32 words
