Overshoe walking corrector

Abstract

The Overshoe Walking Correctors (OWCs) are a medical walking device to go over a user's feet and shoes and changes the shape in the base of their current walking shoes for correcting gait. They need only be used by the obese and overweight population, who suffer limited mobility in their skeletal joints, due to the burden of weight they are carry on their bodies. The device was designed by Gail McGonigal an Occupational Therapist, who discovered the concept after falling on concrete severely bruising but not breaking her hip, due to a daily intake of oral calcium. She was only able to walk in rocker shoes containing no weight bearing capacity. Gail immediately understood how this concept will help the obese population improve their mobility in gait. She has designed the Overshoe Walking Correctors for all overweight people to wear, so they will feel no more pain in gait. The device is designed to have immediate and positive affects on their health, so the overweight population are encouraged to increase their physical mobility, while reducing the amount of sedentary sitting they perform on a daily basis. The intention is to relieve the pressure on acute medical services in all western populations, where obesity is a leading cause of chronic health issues needing constant attention by the medical practioners in acute care hospitals.

Description

BRIEF DESCRIPTION OF PHOTOGRAPHS AND DRAWINGS

(1) FIG. 1 are four photographs of the inventor's bruised hip taken over a few days to demonstrate the severity of the bruise that propagated following a fall onto concrete.

(2) FIG. 2 is a photograph of the inventor's rocker shoe that were the only pair of shoes she was able to use for gait over the next three months, as the pain from the bruise was so severe.

(3) FIG. 3 are two drawings for viewing each side of the device, in-order to see the whole reverse-pull fastening attachment. This is described in more detail in the final section, as the obese suffer medical problems not usually experienced in the healthy populations.

(4) FIG. 4 is the adjustable part of the device with three views: a) Shows the view from under the foot and shoe/foot appliance that is sandwiched between the pendulum base and the shoe/foot appliance. b) Is a view from above looking down into the walking device, and c) is the same as the previous view, but with a cover over the top like any shoe covering.

(5) The current walking device needs to be adjustable, as many obese sufferer's feet need protection from the medical symptoms of obesity, such as diabetes that causes swollen feet and skin trauma that are difficult to heal caused from immobility. These symptoms can be aided by using this device to increase physical mobility in gait, or else their symptoms will worsen leading to ulcers that will seriously jeopardize their overall medical and physical health and threaten their overall functional independence.

(6) FIG. 5 shows the reverse-pull fastening used to hold the device tightly over their shoe/foot appliance and converts the base of the device into their own shoe/foot appliance base.

DETAILED DESCRIPTION OF THE INVENTION

(7) References is made to the attached drawings with reference numbers and letters used to show the changes and the reason for the changes from the original patent of the first walking device. (Patent No: US 2011/0078023 Al, 2011)

(8) The idea for the device began with FIG. 1 with four replacement photographs taken over several days, to show the severity of the bruise that occurred over the inventor's left hip following a fall that prevented her from weight bearing on her left hip for gait. In theory, the inventor should have been able to weight bear, as the hip wasn't broken, only bruised. But the pain from the bruise was so severe that mobility was impossible for gait.

(9) FIG. 2 is a replacement sheet and photograph of the only shoes the inventor could wear throughout the time the bruise remained over her hip that was about three months. The shoes contain a pendulum in the base that may appear insignificant, but was enough to move the weight bearing pressure from static to one continuous motion to create comfortable and pain free gait.

(10) FIG. 3 is a replacement sheet of the current walking device drawn to show each side of the device: a) is the inside of the view of the device and b) is the outside of the device showing the reverse-pull fastening.

(11) Also on FIG. 3 are sequential numbering for explaining each part of the device:

(12) Number 1 is the pendulum shape in the base and the purpose for designing the walking device. It is the most important element to this design for healing the back pain in obesity for gait. The original walking device cannot be used by the obese, as their feet will not safely fit into the original design for comfort, plus the obese cannot reach their feet to do up the shoe laces. Hence, this particular device is designed for considering the medical needs of obesity by allowing the user to wear their own specialized footwear, for overcoming the medical issues of obesity.

(13) Number 2 is the adjustable foot plate, where the individual's shoe/foot appliance lies inside of the walking device and allows the balance of the user to remains upright and safe.

(14) Number 3 is the toe guard on the front and number 4 is the heel guard at the back of the device. Both guards prevent the foot in the shoe/foot appliance from slipping out of the adjustable foot plate in gait.

(15) Number 5 and 6 are the reverse-pull fastenings to hold the shoe/foot appliance tightly inside of the device, so the base of the device now becomes the base of their own shoes/foot appliance for gait. Number 5 is the strap closer to the toes and attaches behind the toes, or across the metatarsal bones and under the adjustable plate.

(16) Number 6 attaches to the heel guard and holds the leg around the ankle, preventing the foot from slipping out of the walking device during the final stage of motion in gait. The foot in the shoe/foot appliance is now very secure to commence normal gait.

(17) Number 7 is the adjustable plate that sits on top of the pendulum, in order to allow different sizes of shoe/foot appliances to to be accommodated. The adjustable plate has a raised lip around the edge that forms into the front and back guards to hold each foot inside the shoe/foot appliance securely. The plate is permanently fixed centrally to the pendulum, so the rest of the foot appliance securely. The plate is permanently fixed centrally to the pendulum, so the rest of the shape can accommodate different sizes of feet and footwear.

(18) Number 8 is the flat-based shoe/foot appliance worn by the obese user, as their footwear are mostly specialized for protecting their fragile feet, due to their poor peripheral circulation from lack of movement in their bodies.

(19) FIG. 4 contains three diagrams of the adjustable plate from different views for understanding how adjustable it is. Section A is a view from underneath the base, to show how adjustable the plate becomes for accommodating different sizes of footwear. Section B is an overhead view of the plate with the adjustable parts hidden and Section C is the same as the previous view, but with a foot covering over the top like any normal shoe cover.

(20) FIG. 4 sits on top of the pendulum base, in order to allow different sizes of shoes/foot appliances to be accommodated in the device. The adjustable plate has a raised lip around the edge forms into the front and back guards and holds each foot securely inside of each shoe/foot appliance on the plate. The plate is permanently fixed at a central point on the pendulum, so that the rest of the shape of the base will accommodate the different sizes of feet and footwear. The plate enables the user's footwear base to becomes. the base of the walking shoes without needing to purchase another pair of shoes for correcting gait.

(21) FIG. 5 is a replacement sheet for the diagram of the two reverse-pull fastenings on each device and shows how the separate parts each make up the fastening, for enabling the obese to operate the fastening independently:

(22) Line A shows one D-ring loop and two loops through small pieces of tape for attaching to the inside view of the device.

(23) Line B is the tape with both sides of the velcro stitched to one side of a length of tape and a D-ring loop remaining unattached at the end. (The D-ring loop needs to be larger than the ring loops so that the tape cannot become be undone once opened).

(24) Line C is the completed fastening, showing how the velcrod tape needs to be threaded through the metal loop before attaching the D-ring loop, so it doesn't become fully undone.

(25) Line D is there to explain the velcrod tape needs be threaded through the D-ring FIRST before being attached and to makes the reverse-pull fastening on the device.

(26) Line E is a dressing stick, which is a piece of wooden dowel with a hook attached to one end. This is simple aid for the obese to avoid reaching down over their body to fasten the device for gait. The metal hook on the the stick hooks onto the loops at the end of the fastening, for opening and closing the device independently.

(27) Line F is a photograph of the inventor using the reverse-pull fastening with a dressing stick stitched to her own shoes as an example. It is a typical fastening for users unable to reach their feet independently, due to obesity or lower limb trauma.

(28) In summary, the current walking device is a medical rehabilitation treatment tool for erasing back pain in the obese population caused by incorrect physical mobility, along with too much sedentary sitting that causes back pain leading to weight gain and medical deterioration in their daily lives. By encouraging them to use this walking device in gait, the goal is to increase physical mobility that will reduce their medical symptoms of inactivity. It will also allow them to broaden their social networks and meet other people with similar goals for weight loss, leading to an increase in their health and well being. The device will also speed up the rehabilitation process in lower limb trauma victims, allowing a return to normal activities much sooner than is normally possible for comfort.
