Abstract
An improved spring support system is disclosed for use in seating or bedding. The invention includes an outer frame having opposed top edges. A plurality of vertically resilient members having top ends and lower ends are fixedly disposed within the outer frame in a plurality of rows and columns. An elastic top sheet is stretched between the opposed top edges of the frame and over the top ends of the vertically resilient members. The resilient top sheet and vertically resilient members cooperate to provide a resilient support surface for supporting a person seated or reclined on the support surface.
Claims26
An improved spring support assembly comprising:
- (a) an outer frame including an open bottom and open top, a front and a back, the front and back having opposed top edges;
- (b) a lower spring support grid affixed to the frame and spanning the open bottom;
- (b) at least two rows of vertically oriented springs having top ends and bottom ends, the bottom ends of the springs being affixed to the lower spring support grid;
- and
- (c) a top sheet having opposed margins, the margins being affixed to the opposed top edges of the outer frame such that the sheet is stretched between the top edges and over the open top of the frame and top ends of the springs, the top sheet being formed of an elastic material, whereby each of the springs is at least partially vertically compressed between the lower spring support grid and the top sheet.
A seat comprising:
- (a) a frame portion comprising opposed front and rear panels and opposed end panels defining a frame interior, the front and rear panels having top and bottom edges and a first height, and the end panels having upper and lower edges and a second height, wherein the bottom edges and lower edges are substantially coplanar and define a bottom support plane;
- (b) a plurality of coil springs having top ends and bottom ends, the springs having an uncompressed spring height which is greater than the first height of the frame side panels, the springs being vertically oriented in at least two rows to form a spaced array of springs within the frame interior;
- (c) a lower spring support grid for laterally fixing and vertically supporting the bottom ends of the coil springs at points proximate the bottom support plane of the frame portion;
- (d) a top sheet formed of knit or woven elastic yarns in at least the warp direction, and having opposed edges, the opposed edges of the sheet being affixed to the top edges of the opposed front and rear panels such that the sheet is stretched between the top edges over the top ends of springs, whereby each of the springs is at least partially vertically compressed between the lower spring support grid and the top sheet.
A box spring comprising:
- (a) an outer frame having opposed top edges;
- (b) a plurality of vertically resilient spring members having top ends and having lower ends which are fixedly disposed within the outer frame in a plurality of rows and columns;
- (c) an elastic top sheet stretched between the opposed top edges of the frame and over the top ends of the vertically resilient members;
- (d) wherein the elastic top sheet and vertically resilient spring members cooperate to provide a resilient support surface for supporting a person seated or reclined on the support surface.
