## Abstract

The outer side of a slide-out floor (20) is supported by the outer end of an inner rail member (40). The inner rail member (40), or at least a support wall thereof, is telescopically angled within an outer rail member (32) such that the angle increases as the inner rail member (40) is extended, so as to position the outer end of the slide-out floor (20) at an elevation that is substantially flush with the fixed floor (74) when the slide-out floor (20) is fully extended.

## Claims

### Claim 1

In a flat floor slide-out assembly having a first floor, a second floor mounted so as to be movable with respect to said first floor between an extended position in which said second floor is a substantially flush extension of said first floor and a retracted position in which at least half of said second floor overlaps said first floor, a first support member mounted under said first floor, and a second support member telescopically mounted to said first support member and having an outer end mounted to said second floor so as to push or pull said second floor between said extended position and said retracted position, the improvement wherein a wall of said second support member on which said second support member is supported is at an outwardly and downwardly inclined angle relative to said first support member in said retracted position, said angle progressively increasing as said second floor is moved from said retracted position to said extended position.

### Claim 2 (depends on 1)

The improvement of claim 1, wherein said first support member is substantially parallel to said first floor.

### Claim 3 (depends on 1)

The improvement of claim 1, wherein said outer end of said second support member is pivotally connected to said second floor.

### Claim 4 (depends on 1)

The improvement of claim 1, wherein said second support member has a first roller arrangement at an inner end of said second support member and said first support member has a second roller arrangement at an outer end of said first support member, said first roller arrangement and said second roller arrangement being positioned to obtain an angle at said extended position which positions an outer end of said second floor substantially coplanar with said first floor in said extended position.

### Claim 5 (depends on 1)

The improvement of claim 1, wherein a vertical spacing between points of contact between said first support member and said second support member, which points of contact establish said angle, is substantially the same in said retracted and extended positions.

### Claim 6 (depends on 1)

The improvement of claim 1, wherein said wall of said second support member on which said second support member is supported is at an angle relative to a wall of said second support member which is opposite from said wall of said second support member on which said second support member is supported.
