The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A self-coiling removable guard comprising:
a flexible main body strip;
a bistable spring strip embedded within the main body strip; and
a flexible magnetic strip attached to said main body strip.
2. The self-coiling removable guard of claim 1 wherein said flexible magnetic strip is composed of a composite of magnetic materials imbedded in a flexible polymer material.
3. The self-coiling removable guard of claim 1 wherein said bistable spring strip has a first stable linear state and a second stable coiled state, wherein said spring strip may be induced to transition from said first stable linear state to said second stable coiled state upon a force being applied by a user to said spring strip so as to bend said spring strip.
4. The self-coiling removable guard of claim 3 wherein said bistable spring strip, when induced by a user to transition from said first stable linear state to said second stable coiled state, produces a coiling force applied to said main body strip, causing said main body strip to coil.
5. The self-coiling removable guard of claim 3 wherein said bistable spring strip, when in its first stable linear state, supports said main body strip in a substantially straight position for attaching to another object.
6. The self-coiling removable guard of claim 1, further comprising a transparent sleeve attached to a top side of said main body strip, said sleeve being adapted to receive printed materials.
7. The self-coiling removable guard of claim 1 wherein said main body strip is composed of high-density polyethylene foam.
8. The self-coiling removable guard of claim 1 further comprising a soft bottom layer that is attached to a bottom side of said guard.
