Description

FIELD OF THE INVENTION

The present invention relates generally to a customizable pressure relieving component. More specifically, the present invention is a footwear component that may be used as a shoe insole insert or as a footwear itself to improve foot function and to relieve foot pain.

BACKGROUND OF THE INVENTION

Soreness and stiffness at certain pressure points and joints are common problems faced by a lot of individuals. However, the position and intensity of these pressure points and soreness change from one individual to the other. The function of a human foot is to support body weight, provide balance, redistribute stresses, and absorb shocks. Further, each individual has a unique foot pattern and a gait as well. When we wear shoes to protect foot, foot loses direct contact with the surface and thus our natural flexibility and ability to redistribute the weight which the barefoot provides is also compromised. So, wearing the shoes that misfit or does not respond to stress, can result in problems associated with foot. While standing or moving, if foot does not adapt to the position and/or redistribute the weight, the resulting unbalanced posture can damage various parts of the body. Foot also have nerve ending connecting to multiple parts of the body. Large populace suffers from various foot-related ailments such as flat foot, knee and ankle pain, plantar fasciitis, bunions, corns etc., which makes foot pain a common problem. A large variety of over the counter (OTC) insoles for foot support are manufactured to address general problems like arch support or flat foot or to sooth pain from corns and bunions. However, most OTC insoles have minimal arch support and cushions in such OTC soles wear down, harden, or shrink and get dirty over time causing more discomfort and prompting periodic replacement. The insole which does not fit properly inside the shoe will distribute body weight in such a way that foot pain may alleviate but can cause knee and calf pain. Custom orthotics prescribed by a doctor and custom-fitted are expensive and mostly reserved for more severe foot problems. Thus, there is a need for an economical, comfortable, durable pressure relieving apparatus, that is effective in redistributing weight while providing support with minimum loss of flexibility. Further, there is a need for a customizable inner sole insert to meet individual needs.

An objective of the present invention is to provide users with a pressure relieving component that may be customized to user's needs and preferences. To that end, the present invention comprises a sleeve with one or more compartments that may be individually filled and refilled with a deformable media. The deformable media further comprises a mixture of both non-rigid deformable and rigid non-deformable particles that enable the device to conform to any shape when acted upon by a pressure and deformable media rearranges back to an alternate configuration when pressure is removed. It is further an aim of the present invention to provide a footwear component for use as a shoe insole insert which may be customized by the user to relieve pain in the areas of foot where most required. In other words, the insole of the present invention is intended to provide cushion and support selectively in various parts of the foot to suit individual needs of the user. According to the present invention, the footwear component adapts to the user's foot pattern while standing or moving. Furthermore, the present invention is durable, washable and reusable. Additionally, the present invention may be used with open shoes, closed shoes or even without any shoes, according to the preferences of the user.

In reference to FIG. 1 through FIG. 6, the present invention is a pressure relieving device. An objective of the present invention is to provide users with a pressure relieving component that may be customized to user's needs and preferences. To that end, the present invention comprises a sleeve with one or more compartments that may be individually filled and refilled with a deformable media. The deformable media further comprises a mixture of both non-rigid deformable and rigid non-deformable particles that enable the device to conform to any shape when acted upon by a pressure and recover back to an alternate configuration when pressure is removed. It is further an aim of the present invention to provide a footwear component for use as a shoe insole insert which may be customized by the user to relieve pain in the areas of foot where most required. In other words, the insole of the present invention is intended to provide cushion and support selectively in various parts of the foot to suit individual needs of the user. According to the present invention, the footwear component adapts to the user's foot pattern while standing or moving. Furthermore, the present invention is durable, washable and reusable.

The following description is in reference to FIG. 1 through FIG. 6. According to a preferred embodiment, the present invention comprises a sleeve 1, a pressure responsive media 2 and at least one pocket 3. Preferably, the sleeve 1 is a sealed enclosure, and the sleeve 1 comprises a first layer 4 and a second layer 5. In the preferred embodiment, the sleeve 1 has the shape of a human feet. As seen in FIG. 1, the first layer 4 and the second layer 5 have identical shapes and the first layer 4 is perimetrically connected to the second layer 5 to form the sealed sleeve 1 with a re-closable gap in between. Preferably the first layer 4 is sewn/stitched with the second layer 5 along the perimeter. However, any other attaching means that are known to one of ordinary skill in the art may be employed to connect the first layer 4 and the second layer 5, as long as the intents of the present invention are not hindered. Examples of such attaching means include, but are not limited to stitching, zipping, using adhesives, hook and loop fasteners etc.

It is an aim of the present invention to provide users with an insole/sleeve that has customizable support and cushioning. In order to accomplish that, one or more pockets are filled with the pressure responsive media 2, wherein the pressure responsive media 2 responds to applied pressure over the sleeve 1. More specifically, the nature and pressure responsiveness of the pressure responsive media 2 indicates, responding to any kind of applied pressure. To that end, the pressure responsive media 2 is distributed within the at least one pocket 3, wherein the at least one pocket 3 is positioned within the sleeve 1. Further, the at least one pocket 3 may be partially filled with the pressure responsive media 2 or the filling be customized according to the user's preferences.

In the preferred embodiment, the pressure responsive media 2 comprises a plurality of discrete particles of non-agglomerating deformation medium, allowing the particles to move relative to each other under pressure. In other words, the pressure responsive media 2 comprises a plurality of discrete particles of non-blocking shape, such that the discrete particles will remain free to move and will not mechanically lock under pressure or motion. As seen in FIG. 3, the discrete non-blocking particles are either deformable non-rigid particles 2a or non-deformable rigid particles 2b. It is further preferred that each of the non-deformable rigid particles 2b are smaller in size than each of the deformable particles 2a, the non-deformable particles 2b have lower rolling resistance than the deformable particles 2a, and each of the plurality of non-deformable particles 2b comprises a non-agglomerating shape. More specifically, a first rolling resistance of the non-deformable particles 2b is lower than a second rolling resistance of the deformable particles 2a. This is so that the non-deformable rigid particles 2b facilitate rolling motion, and hence may roll and move easily from a high-pressure area to a low-pressure area. Furthermore, the plurality of deformable particles 2a conforms to various shapes when applied with a pressure and the pressure responsive media 2 rearranges to an alternate configuration when the pressure is removed. In other words, the deformable particles 2a deform under pressure absorbing impact energy and the non-deformable particles 2a roll to a low-pressure area, thereby providing the right amount of support and cushioning under the user's foot. Thus, the pressure responsive media 2 of the present invention allows the foot of the user to adapt to position and posture, by responding to the applied pressure.

As seen in FIG. 3, the deformable particles 2a may comprise spheres or ellipsoids or cylinders (not shown) with maximum characteristic dimension less than 3 mm. According to the preferred embodiment, the deformable particles 2a may be solid or cellular particles made from elastomers, thermoplastic elastomers, thermoplastic vulcanizates or block copolymers with hardness (ASTM D 2240) ranging from 10 to 70 Shore A (ASTM D 395B), compression set at 30 C, temperature ranging from 10-30, and density of 0.2 g/cc to 1.5 g/cc. Furthermore, because of their lower surface hardness, lower compression set, resiliency and recyclability, solid elastomer particles are preferred over cellular thermoplastics like foam PS (polystyrene) or PP (polypropylene) beads. Additionally, thermoplastic elastomers free of plasticizers or with minimum plasticizers based on EPDM (ethylene propylene diene monomer), SEBS (Styrene-ethylene-butylene-styrene), or PU (polyurethane) are also preferred. However, the hardness of the deformable particles 2a of the pressure responsive medium 2 can be tailored to suite individual needs.

As seen in FIG. 3, the rigid particles 2b can be solid or hollow with substantially spherical shape with low static COF (coefficient of friction) and diameter ranging between 1 and 2 mm. Accordingly, the rigid particles 2b may comprise glass, plastics or naturally occurring organic seeds and have sufficient crush strength to avoid breakage under human weight. Organic seeds are preferred as they are biodegradable. Mustard seeds are preferred as they are of 1 mm size, good crush strength and have a low rolling resistance. However, the relative size of particles of the pressures sensitive media 2 may be varied to create different response to the motion. In the preferred embodiment, the pressure responsive media 2 is deformably coupled within the sleeve 1, such that the pressure responsive media 2 undergoes shape conformation under pressure, as the plurality of non-deformable particles 2b rolls and moves from a high-pressure area to a low-pressure area and the plurality of deformable particles 2a deform under pressure, absorbing impact energy. Thus, the present invention helps alleviate stress and pain for users on high pressure points, by adjusting and deforming to the user's specific needs, without sacrificing the essential support.

According to the preferred embodiment, the pressure responsive medium 2 may be selectively filled into the at least one pocket 3.
