Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
354 words
A fitted sheet comprising: A top panel, side panels and end panels for covering the top, sides and end respectively of a mattress, said side panels and end panels having straight adjacent ends seamed together to form corners extending from the top panel to free marginal edge or edges of the side panels and end panels, the sheet having fullness in the corners and adapted to extend beyond the bottom of the mattress to which it is applied, said side panels and end panels including retaining flap portions or flaps extending from a lower portion of said side panels and end panels to the respective free edge of each said side panels and end panels having fullness in the edges to form an open bottom of the sheet; corner elastic means in each of said corners extending along the seamed length of each corner wherein the resilient force of said elastic means is in a direction parallel to said corner seam for drawing the corners towards the top panel in order to take up fullness of said corners; and edge elastic means extending along entire edge margins of the respective end panels from corner to corner, and at least along selected portions of the side panels, and extending to the corners for drawing said edges inwardly of the top panel in order to take up fullness in said edges, said edge and corner elastic means meeting at the juncture of each respective corner and adjacent ends of the side panels and end panels for drawing the corners and the free edges laterally inwardly of the top panel of said fitted sheet, whereby when said sheet is in position on said mattress, said corner elastic means and said edge elastic means draw the retaining flaps against the underside of the mattress and draw the side panels and end panels and the top panel of the sheet tightly against the mattress without significant bunching, to thereby simultaneously take up fullness in the corners and adjacent edges, said corner and edge elastic means being extensible for removing the fitted sheet from the mattress wthout deforming the same.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
93 words
A fitted sheet as defined in claim 1 in which the side panels and retaining flaps are of a length sufficient to engage the sides and underside of a relatively thick mattress of a given nominal size, and wherein the elasticity of the corner and edge elastic means is sufficient so that when the fitted sheet is applied to a mattress of a relatively lesser thickness than the aforementioned mattress, the respective side, end and top panels and the corners of the fitted sheet are drawn closely against said mattress without significant bunching.
Claim 4
Dependent Claim
26 words
A fitted sheet as defined in claim 1 wherein the edge elastic means extends along the side panels about 10 to 15 inches from each corner.
