Description

Proactive Mobility Device (PMD)

Technical Field

The number of people who find themselves in limited mobility scenarios is increasing by the day. More than often this is owing to the nature of their job occupation. The body is built innately to handle various complex movements. However, the prolonged immobility becomes a significant risk factor for stiffness, loss of range of movements and impaired blood flow. We also see this in cases where subjects are immobile due to either age or even long distance travel.

Background Art

The proactive mobility device allows motion, flexion and increases blood flow while the subject continues to remain in their stationary position for the most part. This invention has several advantages and benefits. The foot pedals allow for a range of motion along the ankles while the piston models and cyclic models take into account higher range of motions for the legs and knees. There are four basic models listed here that apply the same inherent principle of inducing the ability for mobility while the subject is stationary. Please note that we intend to extend this principle to an electronic version of the same with Bluetooth capability so that the activity can be captured on smart apps/devices for tracking and measuring purposes. The same principles can also include rotational motors below the pedals that will allow for movement without the subject having to self-induce the force themselves (passive motion).

Patent CA 2512656 is a simple device which allows the exercise of legs and ankles. There is a need for improvement in such devices in order to be used.

Disclosure of Invention

The invention allows for foot rests that allow mobility compromising of the following components:

1 . Foot pedals: These pedals (Fig. 1 : 1 .1 , Fig. 5: 2.1 , Fig. 8: 3.1 , Fig. 12: 4.1 , Fig.14: 5.1 ) allow (but is not limited to) dorsiflexion, plantarflexion, inversion and eversion.

i. The foot pedals with the joystick joints (Fig. 3, Fig. 4) allow plane based tilts and rotary motion for the ankles (as shown in Fig. 3: 1.1 and Fig. 4: 1.1 ). Model 1 has a total tilt of 30 degrees on each pedal (Fig. 3 and Fig. 4), resulting in a forward, backward, left, and right pedal movement. The pedals in Model 1 have an optional accessory in which the two pedals can be joined by a hook (Fig. 2: 1 .6), resulting in both pedals moving simultaneously.

ii. The foot pedals with the gear ball and track path (Fig. 5) allow for a more guided path based motion allowing the subject's feet to traverse along a set path (Fig. 5: 2.4). The resulting path is in a forward, backward, left, and right motion, in the form of a cross.

iii. The foot pedals with the piston (Fig. 9: 3.2) allow for a resistance/pressure based motion allowing the user to increase the blood flow along the ankles and feet. This feature is unique to Model 3.

iv. The cyclic motion foot pedals (Fig. 4: 4.1 ) allow for a complete forward rotation with the ability to increase the pressure resistance.

v. The circular-based foot pedals (Fig. 16: 5.1 ) allows for a curved up-down swing (Fig. 5) allowing the user a wider range of motion while continuing to remain seated and not adding to the height of the base allowing the same kind of knee flexion as desired.

Joints:

i. The joints for the basic model are joystick-spring based (Fig. 3: 1 .2, 1 .3) allowing for an even tilt in all directions along with allowing the basic yet subtle rotational motion (Fig. 4).

ii. The joint for the motion-track-path (Fig. 5) allow the pedals to be connected to the track via a ball (Fig. 6: 2.2) allowing a smooth glide along a predefined motion path (Fig. 5: 2.4).

iii. The piston-resistant joint (Fig. 9) has the simple piston mechanism (Fig. 9: 3.2) giving the subject the feel of applying the brakes/accelerator of a car.

iv. The cyclic motion model (Fig.13) has the basic full forward rotation (Fig. 12) encompassed in a closed casing (Fig. 13: 4.2).

v. The circular up-down joint has the swing motion (Fig. 16) incorporated to the base (Fig. 14: 5.5) and pedal (Fig. 14: 5.1 ).

The base: The base (Fig. 1 : 1.4, Fig. 5: 2.5, Fig. 8: 3.3, Fig. 12: 4.3, Fig. 14: 5.5) by itself is comprised of two pieces.

i. The lower base level (Fig. 3: 1 .4, Fig. 7: 2.5, Fig. 9: 3.3b, Fig. 13: 4.3b, Fig. 15: 5.4) serves as ground support of the device to the floor with the rubber stoppers (Fig. 3: 1 .5, Fig. 7: 2.6) and/or anti-slip sheets (Fig. 11 b: 3.3b, Fig. 13: 4.3, Fig. 15: 5.4). ii. The top sheet of the base (Fig. 9: 3.3a, Fig. 12: 4.3a) allows for an angulation (Fig.

11 b) of the entire proactive mobility device, so that the angle of the pedals can be adjusted based on the height and inclination (Fig.10b) of the subject when seated. This is applicable for all models.

Best Mode for Carrying Out the Invention

Basic leg motions tend to enhance the blood flow during prolonged immobility of seated subjects (this can range but is not limited to people with office desk jobs, travellers, those who cannot walk that often owing to age). The following devices will allow for basic movements. Two of the models come with no metal allowing it to be an easy travel companion on flights as well as those who require using it in the office. It also keeps the price point low. The other models listed allow for greater traction and range of motion.
