Mobility systems and methods
Described herein are various improvements to mobility devices. These improvements include, for example, adjustable lateral body supports, multi axial supports for accommodating movement of the pelvis during walking, frame folding assemblies for accommodating storage and transportation, detachable support couplings for supportive accessories, foldaway footplate assemblies for allowing users to rest, wheel brake systems, caster wheel systems, suspension support systems, control button assemblies, and center of gravity adjustment assemblies. One or more these improvements can be combined into various mobility devices as will be described in more detail hereinafter.
1 . A gait trainer comprising:
a frame having a lower frame portion and a vertical frame portion; the lower frame portion comprising first and second extended frame portions and a space therebetween; the vertical frame portion comprising at least one patient support;
a leg rest assembly coupled to the lower frame portion, the leg rest assembly comprising:
a frame attachment assembly having first and second spaced apart members, each member having: first and second portions, a mounting opening proximate the first portion and a projection proximate the second portion;
a footplate assembly pivotably connected proximate to the second portion, the footplate assembly comprising:
substantially planar surface for supporting a foot of a user; and
first and second spaced apart bracket portions disposed on sides of the planar surface, each bracket portion having first and second openings for receiving the projection of one of the first and second members; the first and second openings limiting the pivotal movement of the planar surface.
2 . The gait trainer of claim 1 wherein the first opening comprises a notch.
3 . The gait trainer of claim 1 wherein the first and second openings are disposed along an arcuate path.
4 . The gait trainer of claim 1 wherein the mounting opening comprises a non-circular shape and receives therein a section of the lower frame portion to resists turning motion of the frame attachment.
5 . The gait trainer of claim 1 wherein the footplate assembly is mounted to one of the first or second extended frame portions.
6 . The gait trainer of claim 1 wherein a second footplate assembly is mounted to the lower frame portion.
7 . The gait trainer of claim 1 wherein the bracket portion comprises an angled extension and wherein the first and second openings are disposed in the angled extension.
8 . The gait trainer of claim 1 wherein the substantially planar surface comprises a first position extending into the space and wherein the first position is configured to allow the gait trainer to be rolled from a first location to a second location.
9 . The gait trainer of claim 1 wherein the bracket portion comprises a pivoting joint for connecting the substantially planar surface to the frame.
10 . The gait trainer of claim 1 wherein the first and second extended frame portions are horizontally extendable and retractable from the lower frame portion.
11 . The gait trainer of claim 1 wherein the first and second extended frame portions are horizontally telescoping support members that are inserted into corresponding lower frame members of the lower frame portion so as to slidingly extend therefrom or retract thereinto.
12 . The gait trainer of claim 11 wherein a plurality of holes or apertures is provided in the horizontally telescoping support members to releasably fix the position of the telescoping support members relative to the lower frame members.
13 . The gait trainer of claim 1 wherein the first and second extended frame portions are each provided with a wheel hub system for attachment of a wheel.
14 . The gait trainer of claim 1 further comprising a suspension system coupling the at least one patient support to the vertical frame portion.
15 . The gait trainer of claim 1 wherein the projection comprises a stop pin.
16 . The gait trainer of claim 1 wherein the first opening comprises an arcuate notch having:
a first portion that is open to receive the projection,
a second portion having an end wall to contact the projection; and
the first and second portions spaced part by a curved portion.
17 . A mobility system comprising:
a frame having first and second extended frame portions and a space therebetween;
a leg rest assembly coupled to the frame, the leg rest assembly comprising:
a frame attachment assembly having first and second spaced apart members, each member having an upper and lower portion; the upper portion comprising a mount opening and the lower portion comprising a projection;
a footplate assembly pivotably connected proximate the lower portion, the footplate assembly comprising:
a substantially planar foot support surface; and
first and second spaced apart brackets disposed on sides of the planar foot support surface, each bracket comprising first and second openings for receiving the projection; the first and second openings limiting pivotal movement of the foot support surface.
18 . The system of claim 17 wherein the first and second openings are disposed along an arc formed in each of the brackets.
19 . The system of claim 17 wherein the mount opening comprises a non-circular shape and receives therein a section of the frame to resist turning motion of the frame attachment.
20 . A mobility system comprising:
a frame having first and second extended frame portions and a space therebetween;
a leg rest assembly coupled to the frame, the leg rest assembly comprising
first and second spaced apart frame attachment members, each member comprising an upper portion having a mount opening and a lower portion having a projection;
a footplate assembly pivotably connected to the lower portion and comprising first and second spaced apart brackets, each bracket comprising first and second openings for receiving the projection, the first and second openings limiting pivotal movement of the footplate assembly.
21 . The system of claim 20 wherein the first and second openings are disposed along an arc formed in each of the brackets.
22 . The system of claim 20 wherein the mount opening comprises a non-circular shape and receives therein a section of the frame to resist turning motion of the frame attachment.
