Description

FIELD

The present invention relates generally to an insole, and more particularly to an insole that increases the surface area of the foot to provide comfort and support, thereby enabling a user to correct coordination and postural imbalances.

BACKGROUND

Poor postural and body alignment can have a negative impact on one's physical and mental health. Most of the population experiences postural imbalances because of lifestyle choices and unconscious slouching. Continuous poor posture can cause several diseases and disorders with debilitating effects.

Research has proven that sensory foot stimulation can combat postural imbalances. The feet play a major role in allowing one to have awareness of the position and movement of his or her body. This concept is known as proprioception. A classic example of proprioception is when the feet sense that they are on sand or hard cement, and in turn, adjust the position of the body to prevent one from falling. The signals the feet receive from external stimuli comes from the somatosensory system. The somatosensory system is part of the sensory system and allows one to consciously perceive touch, pressure, movement, vibration, position, etc. As the body perceives signals through the feet, sensory neurons transmit responses to the brain to change body alignment.

Most conventional support insoles provide cushioned arch support to the foot when the user moves. These devices provide comfort to the user, but do not continuously correct the user's coordination and postural imbalances while the user is both weight-bearing and non-weight-bearing.

Moreover, conventional sensory insoles stimulate foot receptors through electric currents, electromagnetic waves, or electromagnetic fields controlled by a device placed within the insole or an external device placed near the heel of a shoe. These conventional designs often incorporate wires, circuits, or batteries that create a thick insole that includes all the electronics needed to operate within, or a thin insole with an external housing unit for the electronic components. The art lacks a sensory insole that uses the physiological reflex zones of the foot to stimulate receptors.

Thus, there is a long-felt need for an insole that provides continuous support for the foot and stimulates the sensory receptors of the foot to correct postural imbalances to improve foot alignment and coordination.

SUMMARY

The present invention broadly comprises an insole having a base layer, a top layer fixedly secured to the base layer, a middle layer comprised of the base layer and the top layer positioned between the base layer and the top layer, a pressure projection extending upwardly from within the middle layer and extending past an upper surface of the upper layer, the projection including a disc fixedly secured within the middle layer, an annular ring fixedly secured atop the disc, a circular metal insert fixedly secured atop the disc within the annular ring, the circular metal insert having a horseshoe-shaped aperture therein.

The present invention may also broadly comprise an insole having a base layer, a top layer fixedly secured to the base layer, a middle layer comprised of the base layer and the top layer positioned between the base layer and the top layer, a pressure projection extending upwardly from within the middle layer and extending past an upper surface of the upper layer, the projection including a disc fixedly secured within the middle layer, an annular ring fixedly secured atop the disc, a circular metal insert fixedly secured atop the disc within the annular ring, the circular metal insert having a horseshoe-shaped aperture therein, and a pair of projections, one of said pair of projections positioned proximate an inside arch and one of the pair of projections positioned proximate an outside arch, the pair of projections proximate to a hindfoot region.

The present invention may further comprise a base layer, a top layer fixedly secured to the base layer, a middle layer comprised of the base layer and the top layer positioned between the base layer and the top layer and, a pair of projections, one of the pair of projections positioned proximate an inside arch and one of the pair of projections positioned proximate an outside arch, the pair of projections proximate a hindfoot region, where the inside projection and the outside projection form a wedge on the top layer.

The present invention may still further comprise a base layer, a top layer fixedly secured to the base layer, a middle layer comprised of the base layer and the top layer positioned in between the base layer and the top layer, a projection positioned proximate to an inside arch of a hindfoot region, the projection extending from the top layer and a projection positioned proximate to a midfoot region, the projection of the midfoot region extending from the top layer, where the inside projection and the projection of the midfoot region form a wedge proximate the midfoot region on the top layer.

An object of this insole is to improve the brain-body connection through sensory receptors. The activation of sensory receptors improves feet alignment and corrects postural imbalances. The frequency and vibration resonator in the center of the insole comprised of a disc, zinc annular ring and copper insert with a horseshoe-shaped aperture, stimulates the receptors within the feet as they respond to pressure, stretch, and frequency. The signal from the feet travels through ascending sensory pathways to the brain and arrives at the sensory cortex. The signal then transmits to the motor cortex where the brain adjusts the position of the body. The center projection increases the surface area on the foot to increase sensory feedback. This increased sensory feedback gives the body continuous awareness of its position in space to improve alignment of the feet to correct the position of the knee, hip, or back to improve posture.

This and other objects, features, and advantages of the present disclosure will become readily apparent upon a review of the following detailed description of the disclosure, in view of the drawings and appended claims.

Base 21 preferably has an outer diameter that is greater than the outer diameter of annular ring 22, such that when annular ring 22 is fixed to base 21 an outer ledge is formed on upper surface 21a of base 21 that extends outwardly from the outer diameter of annular ring 22. When pressure projection 20 is fully assembled, metal insert 23 is fixedly secured to upper surface 21a of base 21 within inner edge 22a of annular ring 22, specifically metal insert 23 is fixedly secured to attachment location 21c of upper surface 21a where outer edge 23a of metal insert 23 is within inner edge 22a of annular ring 22. Metal insert 23 includes a substantially central located aperture, horseshoe-shaped aperture 24, where aperture 24 in a preferred embodiment comprises a U-like, or horseshoe-shaped, configuration. In a preferred embodiment, annular ring 22 is comprised of solid zinc. In a preferred embodiment, metal insert 23 is comprised of solid copper.

Adverting now to the second embodiment of the present invention, insole 200 is illustrated in FIGS. 4A-5B.

FIGS. 5A and 5B illustrate a cross-sectional view of insole 200 taken generally along line 5-5 in FIG. 4B. Pressure projection 20 is embedded within the respective layers of insole 200, i.e., base layer 233 (shown in FIGS. 5A and 5B), middle layer 232, and top layer 231. Base layer 233 and middle layer 232 are adhered to top layer 231 via a double-sided adhesive tape, although it should be appreciated that various other methods of binding the base layer and the top layer may be employed, e.g., heat lamination, or other suitable means. Top layer 231 includes bulge 20a which covers, or contains, pressure projection 20 within base layer 233 and middle layer 232. It should be appreciated that middle layer 232 is illustrated to depict the material between base layer 233 and top layer 231 (shown in greater detail in view of FIGS. 5A and 5B). Pressure projection 20 and bulge 20a of insole 200 are of the same construction as that of insole 100, as described supra, and shown in greater detail in view of FIGS. 3A-3C.

Insole 200 is defined by forefoot region 210, midfoot region 211, and hindfoot region 212. Specifically, forefoot region 210 is defined by the toes of the foot of the user, that is, the area where the toes will rest thereon, midfoot region 211 is defined by the arch of the foot of the user and where pressure projection 20 is preferably located, and hindfoot region 212, defined by the heal of the foot of a user, that is, the area where the heal will rest thereon.

Inside arch projection 251 and outside arch projection 252 are preferably located in insole 200 proximate to hindfoot region 212 and partially within midfoot region 211 of insole 200.

Arch projections 251 and 252 could be integral with top layer 231 and middle layer 232, as shown in FIG. 5A. Alternatively, inside arch projection 251a and outside arch projection 252a could be separate components that are affixed to top layer 231, as shown in FIG. 5B.

The difference between insole 100 and insole 200 is the presence of inside arch projection 251 (or 251a) and outside arch projection 252 (or 252a), discussed supra. Inside arch projection 251 and outside arch projection 252 are preferably positioned in between the midfoot region 211 and hindfoot region 212, where inside arch projection 251 is configured on inside arch 213 and outside arch projection 252 is specifically configured on outside arch 214, thereby contacting the inside arch and outside arch of a user's foot that is resting on insole 200. Inside arch projection 251 (or 251a) and outside arch projection 252 (or 252a) form wedge 260, which is a combination of top layer 231, inside arch projection 251 (or 251a) and outside arch projection 252 (or 252a). The benefits imparted by the configuration of wedge 260 are described in greater detail, infra.

Adverting now to the third embodiment of the present invention, insole 300. The following description should be taken in view of FIGS. 6A-7B. FIG. 6A illustrates a perspective view of insole 300 and FIG. 6B illustrates a top view of insole 300. FIGS. 7A and 7B illustrate a cross-sectional view of insole 300 taken generally along line 7-7 in FIG. 6B. Base layer 333 and middle layer 332, are adhered to top layer 331 via a double-sided adhesive tape, although it should be appreciated that various other methods of binding the base layer and the top layer may be employed, e.g., heat lamination, or other suitable means. It should be appreciated that middle layer 332 is illustrated to depict the material between base layer 333 and top layer 331 (shown in greater detail in view of FIGS. 7A and 7B).

The difference between insole 100 and insole 300 is the presence of inside arch projection 351 (or 351a) and outside arch projection 352 (or 352a), and the absence of pressure projection 20, discussed supra. Inside arch projection 351 and outside arch projection 352 are preferably positioned in between the midfoot region 311 and hindfoot region 312, where inside arch projection 351 is configured proximate to inside arch 313 and outside arch projection 352 is specifically configured proximate to outside arch 314, thereby contacting the inside arch and outside arch of a user's foot that is resting on insole 300. Inside arch projection 351 (or 351a) and outside arch projection 352 (or 352a) form wedge 360, which is a combination of top layer 331, inside arch projection 351 (or 351a) and outside arch projection 352 (or 352a). The benefits imparted by the configuration of wedge 360 are described in greater detail, infra.

Adverting now to the fourth embodiment of the present invention, insole 400. The following description should be taken in view of FIGS. 8A-9B. FIG. 8A illustrates a perspective view of insole 400 and FIG. 6B illustrates a top view of insole 400. FIGS. 9A and 9B illustrate a cross-sectional view of insole 400 taken generally along lines 9A-9A and 9B-9B in FIG. 8B, respectively. Base layer 433 and middle layer 432, are adhered to top layer 431 via a double-sided adhesive tape, although it should be appreciated that various other methods of binding the base layer and the top layer may be employed, e.g., heat lamination, or other suitable means. It should be appreciated that middle layer 432 is illustrated to depict the material between base layer 433 and top layer 431 (shown in greater detail in view of FIGS. 9A and 9B).

Insole 400 is defined by forefoot region 410, midfoot region 411, and hindfoot region 412. Specifically, forefoot region 410 is defined by the toes of the foot of the user, that is, the area where the toes will rest thereon, midfoot region 411 is defined by the arch of the foot of the user and hindfoot region 412, defined by the heal of the foot of a user, that is, the area where the heal will rest thereon. Insole 400 includes two sides, inside arch 413 and outside arch 414, where inside arch 413 would be arranged proximate to the inside arch of a user's foot resting on insole 400 and where outside arch 414 would be arranged proximate to the outside arch of a user's foot resting on insole 400.

Insole 400 also comprises inside arch projection 451 and is arranged to have a substantially semicircular configuration, a semi-domed configuration, or a combination thereof. Inside arch projection 451 is preferably located in insole 400 proximate to hindfoot region 412 and partially within midfoot region 411 of insole 400.

Arch projection 451 could be integral with top layer 431 and middle layer 432. Alternatively, inside arch projection 451a could be a separate component that are affixed to top layer 431, as shown in FIG. 9B.

Insole 400 also includes midfoot projection 470. Midfoot projection 470 has a quadrilateral-like shape and has toe end 471 and midfoot end 472. Arranged proximate to midfoot end 472 is midfoot slope 474. Midfoot slope 474 has a straight configuration such that it bifurcates insole 400 within midfoot region 411. Arranged proximate to toe end 471 is toe slope 473. Toe slope 473 has a curved arrangement, unlike midfoot slope 474, where the curve juts outwardly in a substantially central position horizontally and the jut is proximate to forefoot region 410. Midfoot projection may be arranged to extend upwardly from top layer 431 or could be a protrusion extending from middle layer 432 that is covered by top layer 431.

Arch projection 451, midfoot projection 470, and top layer 431 collectively create wedge 480. Wedge 480 is preferably arranged proximate inside arch 413 and within midfoot region 411. The benefits imparted by the configuration of wedge 480 are described in greater detail, infra.

The following description should be taken in view of all of the aforementioned figures. The first and second embodiments of the present invention, insoles 100 and 200 are configured to enhance physical and mental performance, via frequency imparted through the foot of user contacting either insole 100 or 200. This frequency stimulates nerve centers to intensify muscle tone, stability, and mobility. A constant stimulation to the nervous system allows the human brain to create new neural pathways. Feedback from the skin of a person's foot is a primary source of sensory input. This sensory input is supplied to the brain from approximately 100,000 to 200,000 receptors in the sole of each human foot. Limiting the sensory inputs from human feet has been shown to introduce issues of maintaining stability and balance. Pressure projection 20 of insoles 100 and 200 are arranged to provide sensory feedback through a user's foot through constant contact with pressure projection—resolving the issue of losing sensory input that could hinder maintaining stability and balance.

Pressure projection 20 of insoles 100 and 200 provide constant sensory input to a user's nervous system. The constant stimulation of pressure projection allows a user's brain to create new neural networks to resolve poor postural habits that may be introduced from sensory input deprivation. Pressure projection 20 works by:

• • 1. The signal, or sensory input, from the skin of a user's foot travels to their brain through channels known as the ascending sensory pathways;
  • 2. The signal arrives in a user's sensory cortex of the brain, located in your parietal lobe;
  • 3. The signal is then transmitted to the motor cortex located in the frontal lobe;
  • 4. The frontal lobe is the center where a user's brain plans the execution of movement; and,
  • 5. Pressure projection 20 has a configuration that optimizes the signal to provide for accurate movement and proper alignment.

In a study conducted on Mar. 10, 2022, force plate measurements were taken of a member of a law enforcement organization. The measurements were taken of both the right and left feet. The test was conducted with the person wearing insoles without pressure projection 20 and subsequently wearing insole 100. The following chart illustrates the benefits imparted on the law enforcement personal via pressure projection 20 of insole 100. Shown below are the differences measured by the force plate of the law enforcement personal without insole 100 and with insole 100:

Blood Pressure & Grip Strength:

	Without Insole 100	With Insole 100
	Blood Pressure	158/105	138/100
	Grip Strength	151 lbs.	154 lbs.

Foot Posture (Weight Distribution %) without Insole 100:

	Left Foot	Right Foot
	Overall	52.3%	47.7%
	Toes	27.7%	18.4%
	Heel	24.6%	30.0%

It should be noted that a perfect foot posture will distribute the overall weight evenly across the left and right feet, i.e., 50% and 50%, and the respective distribution between the toes and heel of perfect foot posture will be distributed evenly across the toes and heel of the respective foot, i.e., 25% and 25%.

Foot Posture (Weight Distribution %) with Insole 100:

	Left Foot	Right Foot
	Overall	51.6%	48.4%
	Toes	22.9%	23.3%

In the second, third, and fourth embodiments of the present invention, insoles 200 and 300, and 400 all include inside arch projection 251 (or inside arch projection 251a), and outside arch projection 252 (or outside arch projection 252a). In the second and third embodiments of the present invention, insoles 200 and 300 include inside arch projections 251 and 351 and outside arch projections 252 and 352, respectively. If a user of insoles 200 or 300 have his or her rear-foot (heel) poorly stimulated, the user's foot sole receptors are missing vital information from sensory inputs, as described supra, which could result in poor activation of the user's posterior chain. When a user has a rearfoot stimulation deprivation, a common indicator is a forward center of mass of the user. The forward center of mass leads to an array of compensations by the body and brain, thereby requiring the user to expend greater energy in order to stay upright against gravity.

It should be appreciated that inside arch projection 251 and outside arch projection 252, referenced herebelow, should also be taken in consideration of inside arch projection 351 (or 351a) and outside arch projection 352 (or 352a) of insole 300. Inside arch projection 251 (or inside arch projection 251a), and outside arch projection 252 (or outside arch projection 252a) of insoles 200 collectively form wedge 260 (or wedge 360 of insole 300). Wedges 260 is arranged to stimulate the receptors in a user's rear-foot that is contacting insole 200 as wedge 260 imparts a deep pressure and stretch to the rear-foot of a user, as follows:

• • 1. The signal, or sensory input received from the skin of a user's foot travels to the user's brain through ascending sensory pathways;
  • 2. This signal arrives in the user's sensory cortex of their brain, located in their parietal lobe;
  • 3. The signal is then transmitted to the motor cortex located in the frontal lobe.
  • 4. The frontal lobe is the center where a user's brain plans the execution of movement; and,
  • 5. The improved signal allows the user's brain to command proper tonicity of the user's posterior chain—encouraging a neutral center of mass and optimal joint mechanics of movement.

Insole 400 includes inside arch projection 451 and midfoot projection 470, which collectively create wedge 480. Common ailments such as rounded shoulders, tight traps, or the occasional tension headache can be commonly addressed and resolved through engaging the sensory receptors in the foot, particularly the midfoot. When the arches of the foot are poorly stimulated, the individual's receptors are necessarily missing essential signaling information that should be communicated to the brain, which in turn means the brain cannot orchestrate proper alignment, specifically in the individual's lower extremities and pelvis. Other ailments include knocked knees and protruding abdomens, i.e., anterior tilt. Wedge 480 resolves these issues by:

• • 1. The signal, received from the skin of a user's foot travels to the user's brain through ascending sensory pathways;
  • 2. This signal arrives in the user's sensory cortex of their brain, located in their parietal lobe;
  • 3. The signal is then transmitted to the motor cortex located in the frontal lobe;
  • 4. The frontal lobe is the center where a user's brain plans the execution of movement; and,
  • 5. The improved signal provided by wedge 480 allows the user's brain to optimize knee alignment while encouraging a neutral pelvis tilt—inducing a positive, less detrimental, impact on the user's joints.

It should be appreciated that the embodiments as shown are only one of a variety of possible embodiments of the claimed invention.

It will be appreciated that various aspects of the disclosure above and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
