Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to preservers, and more particularly, to moisture absorbing preservers including an expandable bladder surrounded by an absorbing member, all disposed within a moisture permeable cover adapted to deodorize and maximize the draw of moisture from all interior surfaces of a protective covering, such as a shoe, boots, gloves, a helmet and the like.

2. Description of the Related Art

Various solutions have been proposed to deodorize, and remove moisture from a shoe. For example, U.S. Pat. No. 5,291,669 to Khoury et al. discloses a shoe preserver having a wicking portion and an absorbing portion retained within a flexible porous covering. However, the shoe preserver of Khoury et al. is not expandable to snugly fit within shoes of various sizes and shapes. Khoury et al. shoe preserver is specifically made for a particular size and shape of a shoe. Furthermore, since the Khoury et al. shoe preserver is not expandable, it cannot completely come in contact with all interior surfaces of a shoe thereby limiting the ability of the shoe preserver to maximize that moisture drawn from within the shoe.

Likewise, the following other conventionally devices also fail to maximize the amount of moisture being drawn from within the interior of a shoe. U.S. Pat. No. 3,131,036 to Hirschberg discloses a shoe drying device having a porous semi-rigid plastic foam wherein the foam defines a cavity which is filled with a powdered desiccant material. U.S. Pat. No. 896,536 to Hayden discloses a shoe tree having an absorbent sponge material surrounded by a porous fabric, wherein a wooden block or piece is disposed within the sponge material to provide for insertion and removal of the shoe tree. U.S. Pat. No. 2,173,528 to Beale discloses a disinfectant pad including an absorbent material enclosed by a porous covering.

There is still a longstanding need to solve this problem. In accordance with this invention, an exemplary moisture absorbing preserver having an expandable bladder surrounded by an absorbing member, all disposed within a moisture permeable cover adapted to deodorize and maximize the draw of moisture from all interior surfaces of various protective coverings, such as a shoe, boots, gloves, a helmet, and the like.

SUMMARY OF THE INVENTION

The present invention addresses the shortcomings identified in providing a preserver capable of absorbing moisture, as well as to deodorize a protective covering in accordance with this invention.

In one exemplary embodiment, the preserver may be implemented as a shoe preserver including a permeable flexible covering received within a shoe. An absorbing material may be disposed within the permeable flexible covering to retain moisture withdrawn from the interior surface area of the shoe. A bladder including an inlet valve is also disposed within the absorbing material. The bladder is adapted to expand the shoe preserver to completely fill an interior surface area of the shoe.

When the bladder is expanded so that the permeable flexible covering completely fills an interior surface area of the shoe, a pressure force is evenly distributed outward from the air in the bladder throughout the interior surface area of the shoe causing the shoe preserver to be securely wedged into the shoe. Consequently, the shoe preserver is prevented from slipping out of the shoe upon exertion of a sufficient perpendicular force along a strap during transport of the shoe.

Another object of this invention is to integrate a pump with an inlet valve of the bladder. When the bladder is inflated by repeatedly compressing the pump, the permeable flexible covering will completely fill the interior surface area of the shoe.

Yet another aspect of this invention is to integrate an interconnecting flexible strap including a first distal end having a first attachment point adapted to engage the first preserver, at any side and at any attachment point. And, a second distal end having a second attachment point adapted to engage the second preserver, at any side and at any attachment point.

Attachment points may be provided at the distal ends of the interconnecting flexible strap in order to secure the interconnecting flexible strap to the first and second preservers.

These and other objects, features, and/or advantages may accrue from various aspects of embodiments of the present invention, as described in more detail below.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Particular embodiments of the present invention will now be described in greater detail with reference to the figures.

In accordance with this invention, it is to be understood that the preserver described herein may be adapted for use with various different types of protective coverings, and that the various embodiments described and shown herein are not intended to cover all modifications and changes within the scope and spirit of the invention.

FIG. 1 illustrates an exemplary shoe preserver 10 for a shoe 2 in a deflated state. As shown in the deflated state, the preserver 10 resembles the shape of a shriveled foot and includes a toe portion, a heel portion, a sole portion, and a tongue portion. The shoe preserver 10 further includes a permeable flexible covering 20, an absorbing material 30, and a bladder 40.

FIG. 2 depicts the shoe preserver 10 in an operable inflated state in accordance with this invention. As shown in FIGS. 1 and 2, the permeable flexible covering 20 is substantially configured in the shape of a foot. The permeable flexible covering 20 includes a toe end 22 sized to be disposed within the forefoot of the shoe 2 and a heel end 24 sized to placed within the heel portion of the shoe 2.

As shown in the deflated state in FIG. 1, the permeable flexible covering 20 is sized and resembles a shriveled foot. The permeable flexible covering 20 can be expanded to fill the entire volume defined by the interior surface area 4 of the shoe 2 (as shown in FIG. 2). In the deflated state of FIG. 1, the shoe preserver 10 only nominally comes into contact with the internal surface area 4 of the shoe 2. However, in operation and as shown in FIG. 2, when the bladder 40 of the shoe preserver 10 is inflated, the shoe preserver 10 expands and fills the entire volume and internal surface area 4 of the shoe 2. In the inflated state, the shoe preserver 10 comes into direct contact with all of the internal surfaces 4 of the shoe 2.

The permeable flexible covering 20 may be formed from any number of flexible porous material, including but not limited to for example, nylon, spandex, cotton, and/or any other flexible porous material, now known or later discovered in accordance with this invention. Another aspect of the permeable flexible covering 20 is to use a material that is capable of providing sufficient flexibility so that when the bladder 40 (as described in more detail later) expands, the permeable flexible covering 20 can likewise expand to fill the internal compartment of the protective covering such that all internal surfaces may come into contact with the expanded permeable flexible covering 20. The permeable flexible covering 20 may also be capable of allowing aromatic scents there though while preventing the material substance containing the aromatic and/or deodorant from escaping across the permeable flexible covering 20 from within the preserver 10.

The absorbing material 30 is disposed within the permeable flexible covering 20 and is provided to withdraw and retain moisture from within the interior surface area 4 of the shoe 2. The absorbing material 30 may be selected from any number of absorbent, including but not limited to for example, sponge, cotton, foam, gel, cedar chips, a wicking material, and any other suitable absorbent material that biases moisture from the interior surface area of a shoe into the absorbing material, now known or later discovered in accordance with this invention.

It is within the scope of this invention to integrate a separate and/or combined wicking member (not shown) with the absorbing material 30 such that the absorbing material 30 will act to draw, or/or retain moisture from the wicking member from the interior of the shoe 2 into the absorbing material 30.

FIGS. 3-5 illustrate another aspect of this invention in which the absorbing material 30 may be constructed to be self contained separate unit within a permeable flexible liner 34. The flexible liner 34 may be positioned between the permeable flexible covering 20 and the bladder 40. In this construction, the absorbing material 30 may be disposed to evenly encase the bladder 40 such that the absorbing material 30 within the permeable flexible liner 34 may be evenly distributed within the interior volume of the shoe 2 when the bladder 40 is expanded.

The permeable flexible liner 34 may be formed as a compartment 35 by stitching 8 the permeable flexible liner 34 to form the compartment 35 into which the absorbing material 30 may be received, as shown in FIG. 4. FIG. 5 depicts the permeable flexible liner 34 in a closed configuration through whish the inlet vale 42 is extended through an orifice 36 in the permeable flexible liner 34.

FIGS. 6-7 illustrate the bladder 40 in a deflated and an inflated state, respectively. The bladder 40 includes an inlet valve 42 adapted to receive air from an external source, which in turn expands the shoe preserver 10 to a size that completely fills the interior surface area 4 of the shoe 2, as shown in FIG. 2.

The bladder 40 may be inflated in a variety of different ways. In FIG. 6, the bladder 40 is shown substantially deflated having little air disposed therein. In FIG. 7, the bladder 40 is shown substantially inflated by an external source of air. In the shoe 2, the inflated bladder 40 is expanded so that the permeable flexible covering 20 completely fills the interior surface area 4 of the shoe 2. The bladder 40 is positioned so that when it is inflated the bladder is located central to the absorbing material 30 and urges the absorbing material 30 against the inner surface area of the shoes 4.

The bladder 40 may be inflated by manually blowing air into the inlet valve 42 by mouth until the permeable flexible covering bladder 40 expands from the deflated to the inflated state (as shown in FIGS. 6-7) to completely fill the interior surface area 4 of the shoe 2. Alternatively, and as described later, the bladder may be filled by an external pump.

The internal air disposed within the bladder 40 creates an internal pressure force (F, as shown in FIG. 7) within the bladder 40 that is transferred to the shoe preserver 10 that is evenly distributed outward throughout the interior surface area 4 of the shoe 2. The internal pressure force (F) causes the shoe preserver 10 to be securely wedged into the shoe 2. As a result of the built up internal pressure force (F) and the resultant forces acting against the shoe preserver 10, the shoe preserver 10 is securely lodged within the shoe 2 and therefore prevented from slipping out of the shoe 2. The internal pressure force (F) generated by the air pressure in the bladder 40 is substantially strong enough to overcome the exertion of a significantly strong perpendicular forces directed out of the ankle opening of the shoe 2, which would otherwise cause the shoe preserver 10 to be dislodged from the shoe 2.

FIGS. 8-9 depict a simplified pump 50 as another exemplary source for producing air within the bladder 40. In FIGS. 8-9, the pump 40 is integrated as a part of the inlet valve 42 attached to the bladder 40. As shown, the bladder 40 may be inflated by repeatedly compressing a resilient bulb 68 of the pump 50 until the shoe preserver 10 completely fills the interior surface area 4 of the shoe 2.

The pump 50 may be implemented in a variety of different constructions. For example, as shown in FIGS. 8-9, the pump 50 may be integrated as part of the inlet valve 42 and the bladder 40. The pump 50 may be disposed within (as shown in FIGS. 8-9) the shoe preserver 10 and/or on an outer surface (not shown) of the preserver 10 in accordance with this invention.

The location of the pump 50 within the preserver 10 is optimally positioned so that the pump 50 is accessible for use when the preserver 10 is installed in the shoe 2. Various design constructions may be implemented to optimally position the pump 50 in an accessible position when the pump 50 is disposed within the preserver 10. For example, the pump 50 and/or portion thereof may be positioned by being fastened into the preserver 10, such as by being sewn 8 therein (as shown in FIGS. 8-9). As shown in FIGS. 6-7, the inlet valve 42 to the bladder 40 may be optimally positioned to stand adjacent to the ankle opening of the shoe 2. In use, the pump 50 may be attached to the bladder 40 through the ankle opening as shown in FIGS. 1-2. In the alternative, a pouch and/or compartment (not shown) may be formed in which the pump 50 may be placed so that it is always accessible so that the user can inflate the preserver 10.

In the alternative, the pump 50 may be a separable component constructed to work in combination with the preserver 10, 100, 200, 300, 400 as a separate pump system component disconnected from the preserver, as shown in FIGS. 12-15. It is to be understood that various types of pumps may be used in accordance with this invention, including but not limited to, a bicycle pump, an electric pump, a manual pump and/or any other pump now known or later discovered in accordance with this invention.

FIGS. 10-11 depict the pump 50 as a separate pump system 150. In particular and as shown in FIG. 11, the pump system 150 includes a pump 50 having an inlet 53 and an outlet 54 for receiving, and dispensing air. A pair of fluid lines 51, 52 is shown extending from the pump 50. A first fluid line 51 extends from the outlet 54 of the pump 50 adjacent to a first attachment point 55 at a first distal end 56 in which a first outlet valve 57 is disposed. The first outlet valve 57 is adapted to be received by the inlet valve 42 on the bladder 40.

Likewise, a second fluid line 52 extends from the outlet 54 of the pump 50 to a second attachment point 58 at a second distal end 59 in which a second outlet valve (not shown, but similar in construction and operation to the first fluid 51 previously described in FIG. 11) is disposed. The second outlet valve is also adapted to be received by the inlet valve 42 on the other shoe preserver 10.

FIG. 10 further illustrates an interconnecting flexible strap 60 in which a pair of shoe preservers 10 may be carried. The interconnecting flexible strap 60 includes a first distal end 56 having a first attachment point 55 adapted to engage a loop fastener 62 on the preservers 10. The interconnecting flexible strap 60 also includes a second distal end 59 with a second attachment point 58 adapted to engage the other preserver 10. Although the first attachment point 55 is depicted on a first side of the shoe preserver 10, it is to be understood that the attachment points 55, 58 and the associated loop fasteners 62 may be secured on any side of the shoe preserver 10.

Although depicted as a loop fastener 62, the various attachment points 55, 58 of the interconnecting flexible strap 60 may be implemented for use, including but not limited to integrating: snaps, stitches, hook and loop fasteners, adhesives, and/or any other suitable fastener, now known or later discovered in accordance with this invention.

The interconnecting flexible strap 60 may be constructing from any number of various materials, including but not limited to nylon, cotton, plastic, and/or any other durable material for carrying various loads. Likewise, the interconnecting flexible strap 60 may be constructed to include various snaps, stitching, hook and loop fasteners, adhesives, and the like.

In more detail, FIG. 10 illustrates the combination of the interconnecting flexible strap 60 and the pump system 150. As shown, the pump system 150 may be integrated within the interconnecting flexible strap 60. As such, the modified interconnecting flexible strap 60 serves the dual purpose of carrying the shoes 2 including the shoe preservers 10 wedged within the shoes 2, as well as to provide a pumping mechanism to inflate the bladder 40 within the shoe preservers 10.

In use, the bladder 40 is expanded so that the permeable flexible covering 20 can completely fill the interior surface area 4 of the shoe 2. As mentioned before, a pressure force (F) is evenly distributed outward from the bladder 40 throughout the interior surface area 4 of the shoe 2 causing the shoe preserver 10 to be securely wedged into the shoe 2. Consequently, the shoe preserver 10 will be precluded from slipping out of the shoe 2 upon exertion of a sufficient perpendicular force exerted, in the direction of, and along the interconnecting flexible strap 60 during transport of the shoe 2.

As shown in FIG. 11, and in accordance with another aspect of this invention, a deodorant 70 may be disposed within the shoe preserver 10 to impart a pleasant odor to the shoe 2. The deodorant 70 may also be disposed within the permeable flexible covering 20 in order to deodorize the shoe 2 as the absorbing material 30 operates to withdraw moisture from the interior surface area 4 of the shoe 2.

The deodorant 70 may integrated in a variety of different forms, including but not limited to for example, a gel, a powder, cedar chips, a fluid deodorant and/or any other deodorant, now known or later discovered, in accordance with this invention.

Although the preservers 10 are previously described with respect to shoes, it is to be understood that a variety of different embodiments are possible. For example, this invention may be used in combination with any type of protective covering, including but not limited to, a boot, a glove, and/or a hat.
