Featherbed with hourglass construction
View Patent ↗The featherbed includes upper and lower outer fabric sections, which are substantially identical in configuration, secured together along their respective longitudinal and end edges. A plurality of baffle members extend between and are secured to the upper and lower layers substantially from end to end of the featherbed. The baffle members are arranged in pair forms a substantially hourglass configuration.
1. A featherbed, comprising;
upper and lower outer fabric layers, substantially identical in configuration and secured together along their respective longitudinal and end edges;
a plurality of solid connections between the upper and lower layers, each connection having an undulating configuration from end-to-end thereof, in one direction of the featherbed and extending to opposing edges of said featherbed, thereby preventing communication between adjacent internal volumes between the solid connections, wherein the connections are spaced apart in the orthogonal dimension of the featherbed, wherein the connections are positioned in pairs having opposing undulating configurations, generally in the form of hourglass arrangements which include enlarged portions and narrow portions alternating along the length thereof, the enlarged portions being at least three times as wide as the narrow portions, wherein the narrow portions are at least 2½ inches wide to restrict migration of solid filling within the internal volumes while permitting loose solid filling to be blown in to fill the internal volumes; and
loose solid filling positioned within the featherbed between the individual connections and the outer fabric layers.
2. The featherbed of claim 1 , wherein the connections are in the form of fabric baffles which are secured along the lengths thereof to the upper and lower fabric sections.
3. The featherbed of claim 1 , wherein the one direction is the longitudinal direction of the featherbed.
4. The featherbed of claim 1 , wherein the connections are substantially continuous along the length thereof.
5. The featherbed of claim 1 , wherein the narrow portions are approximately 4½ inches wide and approximately 5 inches long, while the enlarged portions are approximately 18 inches wide and approximately 15 inches long.
