The sill trim component comprises a main body portion adapted to be presented to an angle to the vertical for facilitating water drainage thereacross and having a depending apron along its normally outer longitudinal edge. Each trim component embodies a base flange for supported disposition upon an underlying end portion of the sill trim component and a depending skirt for presentation outwardly of the adjacent portion of the sill apron with such skirts incorporating inturned lips for underlying the bottom edge of the apron. ## Claims ### Claim 1 A window trim assembly for use with a building window having a sill and jambs at opposite sides of said window, for the purpose of modifying the appearance of said window, said assembly comprising a sill trim component for covering disposition of said sill including a main or body section of planar configuration and an apron depending from a horizontal edge of said main body portion for obscuring the adjacent edge portion of said sill, said apron having a planar configuration and being in substantially planar perpendicular relationship to said main or body section, and a pair of jamb trim components, each of said jamb trim components having a panel portion for covering disposition of corresponding portions of said jambs, each said panel portion being directed toward the opening of said window and being presented in upstanding relationship to the main or body section of said sill trim component, each said panel portion having a base extension projecting from said panel portion inwardly from the corresponding jamb member toward the opposite panel portion in overlying relation to the adjacent portion of the main or body section of said sill trim component, each base extension including a skirt integral with said base extension extending over the proximate portion of said apron of said sill trim component in covering disposition, and means securing together said sill trim component and jamb trim components. ### Claim 2 (depends on 1) A window trim assembly as defined in claim 1 wherein a plurality of transverse ribs are provided on the undersurface of said main or body section of said sill trim component, said ribs being in inclined relationship to said main or body section so as to be of lesser height adjacent said apron. ### Claim 3 (depends on 2) A window trim assembly as defined in claim 2 wherein said base extension of said jamb trim components is planarwise angularly related to the associated panel portion at substantially the same angle as the angle of inclination of said ribs. ### Claim 4 (depends on 1) A window trim assembly as defined in claim 1 wherein said jamb trim components each incorporate a lateral flange coextensive with the maximum dimension of the associated panel portion, said lateral flange being substantially planarwise perpendicular to said panel portion and to said base extension. ### Claim 5 (depends on 1) A window trim assembly as defined in claim 1 wherein a lip is provided on the lower end edge of each jamb trim component skirt and being turned inwardly beneath the lower edge of said apron. ### Claim 6 (depends on 1) A window trim assembly as defined in claim 1 wherein the panel portion of each jamb trim component contains opposed vertically extending forward and rearward longitudinal edges and upper and lower end edges, said base extension projecting from, and being continuous with, said lower end edge of said panel portion, a lateral flange continuous with said forward longitudinal edge being coextensive therewith and extending in a direction from the plane of said panel portion opposite that from which said base flange extends. ### Claim 7 (depends on 6) A window trim assembly as defined in claim 6 wherein each skirt is coextensive with the combined widths of said base flange and said lateral flange. ### Claim 8 In combination with a room window having an external side and an inner side, said window having a sill and side jambs extending inwardly from the inner side thereof at opposite sides of said sill, a window trim assembly comprising a sill trim component having a main or body section of generally panel formation for disposition upon said window sill in covering relationship thereto, said sill trim component having also an apron depending from the window-remote side of said main or body section, a pair of jamb trim components each of which contains a panel portion for overlying disposition against the related window jamb for covering corresponding portions thereof, a base extension projecting from the lower end portion of the related panel portion for disposition overlyingly upon said sill trim component main or body section, and a skirt depending from an edge portion of said base extension for presentation occludingly of said apron and being of relatively greater vertical extent, and adhesive means for securing said jamb trim components to said window jamb and to said sill trim component and for securing said sill trim component upon said window sill. ### Claim 9 (depends on 8) The combination set forth in claim 8 wherein means are provided on said main or body section of the window sill trim component for disposing said section at an angle of less than 180.degree. to the horizontal for liquid drainage purposes. ### Claim 10 (depends on 8) The combination as defined in claim 8 wherein a plurality of transversely extending ribs are provided on the undersurface of the main or body section of the sill trim component, said ribs inclining downwardly toward the apron thereby presenting said main or body section at an angle to the horizontal for promoting liquid gravity flow thereacross.
