## Abstract

A connector for coupling an object to a substrate has a first flexible member coupled with a second flexible member. The first and second flexible members have corresponding first and second upper regions, and first and second lower region that define first and second intermediate regions. The first upper region is coupled with the second upper region, while the first lower region is coupled with the second lower region. Through this coupling, the first intermediate region is movable relative to the second intermediate region. To minimize damage to the substrate during removal, the first and second flexible members are configured so that application of a normal force, when coupled with the substrate, causes at least the first upper region to form a critical angle sufficient to peel the connector from the substrate. The normal force is generally normal to and in a direction away from the substrate.

## Claims

### Claim 1

A connector for coupling an object to a substrate, the connector comprising:
a first flexible member having a first upper region and a first lower region defining a first intermediate region;
a second flexible member having a second upper region and a second lower region defining a second intermediate region;
the first upper region being coupled with the second upper region,
the first lower region being coupled with the second lower region,
the first intermediate region being movable relative to the second intermediate region,
the first and second flexible members being configured so that application of a normal force, when coupled with the substrate, causes at least the first upper region to form a critical angle sufficient to peel the connector from the substrate, the normal force being generally normal to and in a direction away from the substrate.

### Claim 2 (depends on 1)

The connector of claim 1 wherein the first upper region and the first lower region include a material configured not to adhere with the substrate.

### Claim 3 (depends on 1)

The connector of claim 1 wherein the first intermediate region has a first inner surface and the second intermediate region has a second inner surface, the first inner surface being configured not to adhere with the second inner surface.

### Claim 4 (depends on 1)

The connector of claim 1 wherein the first intermediate region has a first inner surface and the second intermediate region has a second inner surface, the first inner surface having a stiffening material.

### Claim 5 (depends on 1)

The connector of claim 1 wherein the first flexible member includes a foam layer at least partly coated with a layer of elastomeric adhesive.

### Claim 6 (depends on 1)

The connector of claim 1 wherein the first intermediate region has a first outer surface having a layer of elastomeric adhesive configured to removably couple with the substrate or an object, the elastomeric adhesive being configured to cause the first outer surface to peel from the substrate at an angle equal to or greater than the critical angle.

### Claim 7 (depends on 1)

The connector of claim 1 further comprising a permanent adhesive coupling the first upper region with the second upper region.

### Claim 8 (depends on 1)

The connector of claim 1 wherein the first and second flexible members are configured so that application of the normal force causes the first intermediate region to separate from the second intermediate region.
