Abstract
Abstract A shutter construction comprising a plurality of slats within a rigid frame. The slats are placed within the frame by means of a plurality of adapters which fit into a groove in the side pieces of the frame. Projections on the adapters project into the rolled edges of the slats thus permitting the slats to be slid down the grooves in the frame. The adapter may consist of two sections so that the slats may be pivoted with respect to the frame.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
A shutter for use in combination with a wall opening and adapted to be positioned in overlying relation to the wall opening, comprising: a peripheral frame comprising two side pieces, a top piece and a bottom piece, said side pieces having longitudinal grooves therein, said grooves opening toward one another; a plurality of adapters each having a strip section and a crossbar section, said strip section slidably fitting into one of said grooves and said crossbar section having two slat projections thereon; and a plurality of slats having rolled edges, said slat projections on said crossbar section of said adapters fitting into the rolled edges of said slats.
Claim 2
Dependent Claim
108 words
A shutter for use in combination with a wall opening and adapted to be positioned in overlying relation to the wall opening, comprising: a peripheral frame comprising two side pieces, a top piece and a bottom piece, said side pieces having longitudinal grooves therein, said grooves opening toward one another; a plurality of adapters each having a strip section and a crossbar section, said strip section slidably fitting into one of said grooves and said crossbar section having two slat projections thereon; and a plurality of slats having rolled edges, said slat projections on said crossbar section of said adapters fitting into the rolled edges of said slats.
Claim 3
Dependent Claim
22 words
A shutter in accordance with claim 1, wherein said crossbar section is integral with said strip sections on each of said adapters.
Claim 4
Dependent Claim
57 words
A shutter in accordance with claim 1, wherein each of said adapters comprise two separate pieces, one being said strip section and the other being said crossbar section and wherein said strip section has a hole therein and said crossbar section has a pivotal projection thereon, said pivotal projection fitting into said hole in said strip section.
Claim 5
Dependent Claim
65 words
A shutter in accordance with claim 3 wherein: said hole in said strip section is round and said pivotal projection on said crossbar section is round and said hole and said pivotal projection are of a size relative to one another such that said pivotal projection fits tightly into said hole and said crossbar section will be held by friction at any set rotational position.
Claim 6
Dependent Claim
68 words
A shutter in accordance with claim 3 wherein: said hole is generally round with a plurality of rises around the circumference thereof, and said pivotal projection is generally round in cross-section with a plurality of teeth on the circumference thereof, said teeth of said pivotal projection being adapted to intermesh with said rises of said hole such that said crossbar will be held in any set rotational position.
Claim 7
Dependent Claim
53 words
A shutter in accordance with claim 5 wherein said strip section and said crossbar section are constructed of a rigid but yieldable plastic such that said pivotal projection may be rotated within said hole, said teeth and said rises acting as a ratchet mechanism to hold said crossbar at any set rotational position.
Claim 8
Dependent Claim
30 words
A shutter in accordance with claim 3 further including: a bar attached to each of said slats for controlling the rotational position of all of said slats at one time.
Claim 9
Dependent Claim
23 words
A shutter in accordance with claim 7 wherein said bar is located on the side of the shutter closest to the wall opening.
Claim 10
Dependent Claim
22 words
A shutter in accordance with claim 1 wherein: each of said slats has a plurality of vents therein for light and ventilation.
