## Abstract

The stairway includes a stairway backing, a plurality of paired step anchors affixed to the stairway backing, and a plurality of detachable step members secured between the paired step anchors. The step anchors are affixed to the stairway backing and are spaced vertically apart from one another and paired together to form top and bottom anchors for detachably securing the step members. Each step anchor has an anchor base, which is sewn or bonded directly to the stairway backing and an anchor flap, which is adapted and constructed to fold over the anchor base. The outer face of the anchor bases and anchor flaps are covered in hook and loop fastener material. The replaceable step members form the steps or rungs of the stairway. Each step member has a main body and pair of opposed step flanges covered with hook and loop fastener material for mating to the hook and loop fastener material of the step anchors. The step flanges are interposed between the anchor base and the anchor flaps, which folds back over the anchor base.

## Claims

### Claim 1

A stairway assembly for an inflatable structure comprising:
a stairway backing affixed to the inflatable structure;
a pair of step anchors affixed along the length of the stairway backing; and
a step member detachably mounted to the stairway back between one of the pair of step anchors.

### Claim 2 (depends on 1)

The stairway assembly of claim 1 wherein each of the pair of step anchors includes a first anchor member and a second anchor member spaced from the first anchor member along the stairway backing for receiving the step member there between.

### Claim 3 (depends on 2)

The stairway assembly of claim 2 wherein each of the first anchor member and the second anchor member includes an anchor base affixed to the stairway backing and an integral anchor flap that folds over the flat base part to secure the step member.

### Claim 4 (depends on 3)

The stairway assembly of claim 3 wherein the step member includes a step body and a pair of step flanges extending from opposite sides of the step body.

### Claim 5 (depends on 4)

The stairway assembly of claim 4 wherein the pair of step flanges is restrictively secured to and interposed between the anchor flat base and the anchor flap of the first anchor member and second anchor member when the step member is mounted to the stairway backing.

### Claim 6 (depends on 5)

The stairway assembly of claim 5 wherein the pair of step flanges has opposed flange sides, each of the opposed flange sides has hook and loop fasteners mounted thereto.

### Claim 7 (depends on 6)

The stairway assembly of claim 6 wherein the anchor base has hook and loop fasteners mounted thereto for mating with the hook and loop fasteners on one of the opposed flange sides of the pair of step flanges, the anchor flap has hook and loop fasteners mounted thereto for mating with the hook and loop fasteners on the other one of the opposed flange sides of the pair of step flanges.

### Claim 8

A stairway assembly for an inflatable structure comprising:
a stairway backing affixed to the inflatable structure;
a plurality of paired step anchors affixed along the length of the stairway backing; and
a plurality of step members detachably mounted to the stairway backing between one of the plurality of paired step anchors,
each of the plurality of paired of step anchors includes a first anchor member and a second anchor member space from the first anchor member along the stairway backing for receiving the step member there between, each of the first anchor member and the second anchor member includes an anchor base affixed to the stairway backing and an integral anchor flap that folds over the flat base part to secure the step member,
each of the plurality of step members includes a step body and a pair of step flanges extending from opposite sides of the step body, the pair of step flanges is restrictively secured to and interposed between the anchor flat base and the anchor flap of the first anchor member and second anchor member when the plurality of step members are mounted to the stairway backing, the pair of step flanges has opposed flange sides, each of the opposed flange sides has hook and loop fasteners mounted thereto,
the anchor base has hook and loop fasteners mounted thereto for mating with the hook and loop fasteners on one of the opposed flange sides of the pair of step flanges, the anchor flap has hook and loop fasteners mounted thereto for mating with the hook and loop fasteners on the other one of the opposed flange sides of the pair of step flanges.
