Women's Malleable and Resilient Shoe-Tree

Abstract

A shoe-tree that allows the user to care for and maintain the form of their shoes when not in use by employing a malleable form that can be molded to the shape and contour of the interior of said shoe, regardless of heel height. The shoe tree has a malleable, foam like soft body and a solid yet resilient and moldable infrastructure that allows the user to also bend the shoe-tree back to its original shape or to the shape to accommodate another shoe with a different heel height and interior shape. The invention, when inserted into a shoe, extends vertically beyond the interior heel area of the shoe to mimic the shape of the ankle. In this way, the shoe-tree is able to accommodate the straps, buckles and/or closures of the shoe by allowing them to wrap around the shoe-tree to maintain their intended form when the shoe is not in use.

2. The malleable and resilient shoe-tree of claim 1, wherein said soft resilient body is comprised of a closed cell foam, an open cell foam, rubber, horse hair, cotton, flocked material or felted material or any combination of the above listed pliable and resilient materials.

3. The malleable and resilient shoe-tree of claim 2, wherein said malleable infrastructure is comprised of a material including but not limited to metal, plastic, rubber, resin, wood, stone, horn, bone, metal, glass or ceramic or any combination of the above listed materials.

4. The malleable and resilient shoe-tree of claim 3, with an optional cap, wherein said cap is comprised of leather, plastic, rubber, resin, wood, stone, horn, bone, metal, glass or ceramic or any combination of the above listed materials.

5. The malleable and resilient shoe-tree of claim 4, with an optional textile covering, wherein said textile covering is comprised of any woven or non-woven fabric.

6. The malleable and resilient shoe-tree of claim 5, with an optional knob or ring pull, wherein said knob or ring pull is comprised of a material including but not limited to metal, plastic, rubber, resin, wood, stone, horn, bone, glass or ceramic or any combination of the above listed materials.

DETAILED DESCRIPTION OF THE INVENTION

[0044] The infrastructure of the invention has 4 pieces.

[0045] The toe part of the malleable infrastructure 34, the heel part of the malleable infrastructure 26 and the ankle part of the malleable infrastructure 16 are plastic parts made by reaction injection molding or CNC cutting.

[0046] The three plastic parts are connected by a flexible strap 42 that is stamped from a sheet of metal. The strap must be stamped or cut from a thickness of metal that is thin and pliable enough to allow the user to bend it with ease, but also thick and strong enough to hold its shape and hold the shape of the foam body of the shoe tree 12 when bent and in use in the interior of a shoe.

[0047] The top end of the flexible strap 42 is then slid into the flexible strap slot 22 of the ankle part of the malleable infrastructure. A screw 46 is then inserted thru the screw hole of the flexible strap 44 and secured into the screw hole in the ankle part of the malleable infrastructure 24. The bottom end of the flexible strap is then slid into the toe part of malleable infrastructure flexible strap slot 36. A screw 46 is then inserted thru the screw hole of the flexible strap 44 and secured into the screw hole in the toe part of the malleable infrastructure 38.

[0048] The central portion of the flexible strap 42 there is a cross piece that is connected to the heel portion of the malleable infrastructure 26 thru the screw holes in the cross portion of the strap 44 and then secured into the screw holes in the heel part of the malleable infrastructure 30 with two screws 46.

[0049] The malleable infrastructure piece as assembled is then placed inside of a mold that is injected with foam and formed to the shape of the body of the shoe-tree. During this part of the process, pins are used inside the mold to hold the infrastructure in place in the center of the mold to secure that the entire piece is covered in the foam.

[0050] After the injection molding process, the foam body 12 of the shoe-tree is then placed inside of the fabric covering 14 of the shoe-tree. The fabric covering 14 of the shoe-tree is a sock-like covering that is slid onto the foam body 12 of the shoe-tree beginning at the toe area. The fabric cover 14 encases and protects the foam body 12 and allows the user to more easily slide the shoe-tree into a shoe. Any remaining surplus fabric from the covering 14 is then gathered and hidden under a rigid cap 48 that is placed over the ankle portion of the malleable infrastructure 16 and secured in place with the knob screw post 54. The screw end of the knob is put thru the screw hole 50 in the rigid cap 48 and is screwed into the screw hole 18 that is in the concave shaped top of the ankle part of the malleable infrastructure piece 20.

[0051] Once assembled and in use, the shoe-tree 10 is bent to the angle to correspond to the interior of a shoe based upon the height of the heel of the shoe and inserted in said shoe 68. To remove the shoe-tree 10 from the shoe, the user simply uses the knob 52 at the top of the piece to pull the shoe-tree from the shoe. The shoe-tree 10 can then be used in another shoe with the same corresponding interior angle (heel height) or bent to work in a shoe with a different interior angle (heel height).

[0052] The flexible strap 42 is the malleable component that allows the user to bend the shoe-tree to their desired shape, while the ankle part of the malleable infrastructure 16, the heel part of the malleable infrastructure 26, and the toe part of the malleable infrastructure 34 provide the stability to the foam body 12 of the shoe-tree to keep the shape of the shoe tree as it is bent in various ways. Connecting the three rigid pieces at ankle 16, heel 26 and toe 34 to the flexible strap 42 creates an infrastructure for the shoe-tree 10 to ensure the shoe-tree will bend on the proper axis and not lose its shape over time. FIG. 6 shows the invention in another exemplary shoe 70 with a heel height and resulting angle that is different from the angle shown in FIG. 5. As shown in this sectional drawing (FIG. 6) the invention also extends beyond the heel area of the shoe to allow the user to secure the shoe's ankle strap around the invention and thus further protect the materials of the shoe.

[0053] The above description illustrates the principles of the invention and how the components of the invention could be manufactured, assembled and function together to create the invention. Said description is not meant to limit the invention to this method of manufacturing, but rather is used for illustrative purposes to explain the invention and its various components and parts. Variations on the dimensions, materials and method of assembly are intended to fall under the scope of the invention.
