Abstract

Claims (11)

1. A bootie application device comprising:

a rail system including a first set of rails disposed adjacent a first side of the bootie application device and a second set of rails disposed adjacent a second side of the bootie application device opposite the first side of the bootie application device, the first set of rails operable to receive one or more tabs disposed on one end of a bootie and the second set of rails operable to receive one or more tabs disposed on a second end of the bootie such that the bootie is operable to slide from an upper portion of the rail system to a lower portion of the rail system and spacing between the first and second set of rails stretches the bootie along its width for assisting application of the bootie to a foot of a user adjacent the lower portion of the rail system; and

a tensioning apparatus connected to at least one of the first and second set of rails, the tensioning apparatus operable to adjust the spacing between the first and second set of rails based on the width of the bootie being received by the rail system and applied to the foot of the user.

2. The bootie application device of claim 1 , wherein the tensioning apparatus comprises at least one of leaf springs, coil springs, and thermoplastic members operable to expand the spacing between the first and second set of rails when an increased tension is applied to the rail system and operable to contract the spacing between the first and second set of rails when the increased tension is removed from the rail system.

3. The bootie application device of claim 1 , wherein the tensioning apparatus comprises a manually-adjustable portion operable to contract the spacing between the first and second set of rails when an increased tension is applied to the rail system and operable to expand the spacing between the first and second set of rails when the increased tension is removed from the rail system.

4. A bootie application device comprising:

a rail system including a first set of rails disposed adjacent a first side of the bootie application device and a second set of rails disposed adjacent a second side of the bootie application device opposite the first side of the bootie application device, the first set of rails operable to receive one or more tabs disposed on one end of a bootie and the second set of rails operable to receive one or more tabs disposed on a second end of the bootie such that the bootie is operable to slide from an upper portion of the rail system to a lower portion of the rail system and spacing between the first and second set of rails stretches the bootie along its width for assisting application of the bootie to a foot of a user adjacent the lower portion of the rail system; and

a tensioning apparatus connected to at least one of the first and second set of rails operable to adjust the spacing between the first and second set of rails based on the width of the bootie being received by the rail system and applied to the foot of the user, the tensioning apparatus comprising:

a manually adjustable tensioning member operable to contract the spacing between the first and second set of rails when an increased tension is applied to the rail system and operable to expand the spacing between the first and second set of rails when the increased tension is removed from the rail system, and

an automatically adjustable tensioning member operable to expand the spacing between the first and second set of rails when an increased tension is applied to the rail system and operable to contract the spacing between the first and second set of rails when the increased tension is removed from the rail system.

5. The bootie application device of claim 4 , wherein the automatically adjustable tensioning member comprises at least one of leaf springs, coil springs, and thermoplastic members.
