Abstract
Abstract A frame formed at least in part of metal and adapted to be combined with a box spring assembly to provide a support for the spring assembly. The frame is generally rectangular and consists of side and end frame rails and a plurality of spaced cross rails connected to and extended between the side rails, the majority of the springs being mounted in pairs of aligned slots formed in the cross rails. Two forms of the invention are disclosed, an all metal form and a combination wood and metal form in which the side and end rails are made of wood. In the all metal form, wood strips and plastic strips are assembled with the side and end rails so as to provide tacking surfaces on which the conventional cloth cover for the box spring assembly can be mounted.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
A generally rectangular frame for a box spring assembly which includes a plurality of connected wire springs, each of said springs having a body portion located a predetermined distance above said frame and depending mounting portions having ends which terminate in substantially horizontal attaching portions, said frame comprising side and end frame rails and spaced cross rails extending between said side rails, each of said cross rails being formed of a rigid material and having upright leg sections which are horizontally spaced, said leg sections being connected together at one of their ends and the space between said legs being open at their other ends, said leg sections being formed with a plurality of slots arranged in horizontally aligned pairs, and said spring attaching portions on at least some of said springs being extended horizontally through pairs of said slots and being spring biased into frictional engagement with said leg sections at the ends of said slots as to mount said springs on said cross rails.
Claim 2
Dependent Claim
166 words
A generally rectangular frame for a box spring assembly which includes a plurality of connected wire springs, each of said springs having a body portion located a predetermined distance above said frame and depending mounting portions having ends which terminate in substantially horizontal attaching portions, said frame comprising side and end frame rails and spaced cross rails extending between said side rails, each of said cross rails being formed of a rigid material and having upright leg sections which are horizontally spaced, said leg sections being connected together at one of their ends and the space between said legs being open at their other ends, said leg sections being formed with a plurality of slots arranged in horizontally aligned pairs, and said spring attaching portions on at least some of said springs being extended horizontally through pairs of said slots and being spring biased into frictional engagement with said leg sections at the ends of said slots as to mount said springs on said cross rails.
Claim 3
Dependent Claim
59 words
A frame according to claim 1 wherein said side and end rails are formed of wood and said cross rails are secured at the ends thereof to said side rails, and further including a support bar secured at the ends thereof to said end rails and disposed in a supporting relation with said cross rails intermediate the ends thereof.
Claim 4
Dependent Claim
51 words
A frame according to claim 1 wherein each of said spring attaching portions is of generally U-shape having a pair of leg portions which are spring biased so that they tend to spring away from each other and frictionally engage said cross rail leg sections at the ends of said slots.
Claim 5
Dependent Claim
56 words
A frame according to claim 3 wherein one of said attaching leg portions is formed adjacent one end with a curved substantially hook shape section positioned in one of said slots so as to engage a cross rail at the end of said one slot and prevent movement of said attaching portion out of said slot.
