Abstract
Abstract A series of parallel, equally spaced channels support a series of depending baffles below a light or series of lights. The baffles are spaced equally along the respective channels and have a width less than their own spacing but greater than the distance between supports to provide an overlap of the edges of adjacent light intersecting baffles, when turned angularly, such as 45*, to the channels and in alternating angular positions on adjacent channels. The baffles are held in the angular positions by clips cooperating with spaced slots in the channels and centrally disposed holes in a right angled portion of the respective baffles. These holes are slanted, rectangular or octagonally pointed. When turned in alignment with the channels to form rows, the baffles are readily cleaned.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
146 words
An illuminator grid adapted to be disposed beneath a source of light to intercept direct light rays disposed at less than a predetermined angle to the horizontal, comprising: a substantially horizontal array of substantially parallel and substantially equally spaced supports; a series of baffles depending from said supports at substantially equally spaced positions along each support and in interspaced positions on adjacent supports; means connecting each baffle with the corresponding support to permit each baffle to be turned on the corresponding support to an aligned position and to a position angular to the support, with baffles on alternating supports being oppositely inclined to the baffles on the supports therebetween; the width of said baffles being less than the center to center spacing of said baffles on the corresponding support; and the width of said baffles being greater than the center to center distance between said supports.
Claim 2
Dependent Claim
146 words
An illuminator grid adapted to be disposed beneath a source of light to intercept direct light rays disposed at less than a predetermined angle to the horizontal, comprising: a substantially horizontal array of substantially parallel and substantially equally spaced supports; a series of baffles depending from said supports at substantially equally spaced positions along each support and in interspaced positions on adjacent supports; means connecting each baffle with the corresponding support to permit each baffle to be turned on the corresponding support to an aligned position and to a position angular to the support, with baffles on alternating supports being oppositely inclined to the baffles on the supports therebetween; the width of said baffles being less than the center to center spacing of said baffles on the corresponding support; and the width of said baffles being greater than the center to center distance between said supports.
Claim 3
Dependent Claim
46 words
An illuminator grid as defined in claim 1, wherein: said means connecting each baffle with the corresponding support is constructed and arranged to hold said baffles in a shifted position of alignment with said support and a shifted position of 45* with respect to said support.
Claim 4
Dependent Claim
38 words
An illuminator grid as defined in claim 2, including: a resilient device for attaching each said baffle to its support; and generally registering openings in said support and a portion of said baffle for receiving said resilient device.
Claim 5
Dependent Claim
36 words
An illuminator grid as defined in claim 3, wherein said generally registering openings include: a slot in said support; and an opening in a portion of said baffle generally perpendicular to the remainder of said baffle.
Claim 6
Dependent Claim
51 words
An illuminator grid as defined in claim 4, wherein said portion of said baffle comprises: an integral, normally upper first portion of said baffle but perpendicular to the remainder of said baffle; and a second integral portion coplanar with said first portion but severed from said baffle adjacent said first portion.
Claim 7
Dependent Claim
70 words
An illuminator grid as defined in claim 1, including: a resilient device for attaching each said baffle to its support; generally registering openings for receiving said resilient device including a slot in said support and an opening in a portion of said baffle generally perpendicular to the remainder of said baffle; and said baffle opening is generally rectangular but is inclined in opposite directions for baffles attached to alternate supports.
Claim 8
Dependent Claim
87 words
An illuminator grid as defined in claim 1, including: a resilient device for attaching each said baffle to its support; generally registering openings for receiving said resilient device including a slot in said support and an opening in a portion of said baffle generally perpendicular to the remainder of said baffle; and said baffle opening is generally octagonally pointed, to engage opposite sides of said resilient device to hold said baffle in alignment with and at a plurality of selected angular positions with respect to said support.
Claim 9
Dependent Claim
156 words
An illuminator grid adapted to be disposed beneath a source of light to intercept direct light rays disposed at less than a predetermined angle to the horizontal, comprising: a series of baffles extending in the same direction away from said light source; means for turnably supporting said baffles for movement to two positions in the first of which said baffles are disposed in generally perpendicular relation in each row and in adjacent rows, and in the second of which said baffles are in aligment in parallel rows angular to the rows of said first position; in said first position, the width of said baffles being greater than the center to center distance between adjacent baffles of the same row and also greater than the center to center distance between said rows; and in said second position, the width of said baffles is less than the center to center spacing of said baffles in the same row.
Claim 10
Dependent Claim
156 words
An illuminator grid adapted to be disposed beneath a source of light to intercept direct light rays disposed at less than a predetermined angle to the horizontal, comprising: a series of baffles extending in the same direction away from said light source; means for turnably supporting said baffles for movement to two positions in the first of which said baffles are disposed in generally perpendicular relation in each row and in adjacent rows, and in the second of which said baffles are in aligment in parallel rows angular to the rows of said first position; in said first position, the width of said baffles being greater than the center to center distance between adjacent baffles of the same row and also greater than the center to center distance between said rows; and in said second position, the width of said baffles is less than the center to center spacing of said baffles in the same row.
Claim 11
Dependent Claim
38 words
An illuminator grid aS defined in claim 8, wherein: said supporting means permits said baffles to be shifted to positions in alignment in a second series of rows disposed at an acute angle to said first mentioned rows.
Claim 12
Dependent Claim
24 words
An illuminator grid as defined in claim 9, wherein said second series of rows are disposed at about 45* to said first mentioned rows.
Claim 13
Dependent Claim
58 words
An illuminator grid as defined in claim 1, wherein said baffle comprises: a flat, sheet-like first member having a predetermined width and height; means connected to said first member providing a second member generally perpendicular to said first member and disposed at one end thereof; and an opening in said second member having a generally octagonally pointed configuration.
Claim 14
Dependent Claim
48 words
An illuminator grid as defined in claim 11, wherein: said second member is integral with said first member and comprises a bent over portion of said end of said first member carrying in coplanar relation therewith a lug severed from said first member immediately adjacent said second member.
Claim 15
Dependent Claim
38 words
An illuminator grid as defined in claim 11, wherein: said first member and said second member are formed of different material; and said second member is attached to said first member by an extension of said second member.
Claim 16
Dependent Claim
24 words
An illuminator grid as defined in claim 13, wherein: said first member is formed of plastic; and said second member is formed of metal.
