A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

The present invention relates to a footrest device for a wheelchair, and more particularly to a footrest device and safety device for a wheelchair, in which a footrest provided in a lower side of the wheelchair moves up and down in accordance with a weight applied by a foot of a sitting person, thereby preventing a falling accident caused by stepping on the footrest when the sitting person rises from or sits in the wheelchair.

The presently disclosure describes a motion assistance system for a wheelchair, for example, a powered drive wheel system that can continually drive a wheelchair in a circular or elliptical path. The motion assistance system comprises a mounting mechanism attachable to one or more structural elements of the wheelchair, and a drive linkage pivotable with respect to the mounting mechanism. A drive wheel can be mounted to an end of the drive linkage such that the drive wheel contacts the ground when installed on the wheelchair. The drive wheel comprises a plurality of lateral rollers positioned radially about the circumference of the power drive wheel. The lateral rollers can rotate about an axis tangential to the circumference of the drive wheel in order to facilitate driving the wheelchair in a radial direction.

EXOSKELETON WITH CAMBERED WHEELS FOR HUMAN LOCOMOTION, comprises an orthosis in the form and function of exoskeleton articulated with actuators, and cambered wheels (9, 10) integrated between the lower limbs of the user for human locomotion, mainly intended for people with motor physical disabilities, being a motorized and intuitively controlled by the user (6) and by balance sensors, joystick (8), central RF (7), gyroscope, magnetometer, accelerometer, containing an inertial disk balancing system (19, 50), also has actuator to articulate the user between sitting and standing position, all systems being integrated electronically to a central control CPU (16) also covering the functions of starting, brake, steering and balance, traction control, up and down stairs.

The present disclosure relates to a locking mechanism (7) of an armrest assembly for a wheelchair, comprising: an elongated inner arm (9) having a pivot end portion (9a), and a first elongated body (9b) extending from the pivot end portion (9a), an elongated outer profile (11) having a proximal outer profile end face (11a) provided with an axially extending channel (11b) configured to receive the first elongated body (9b), and a distal outer profile end portion (11c), the outer profile (11) being configured to move linearly relative to the inner arm (9), between a proximal position relative to the pivot end portion (9a) and a distal position, a locking handle (13) having a second elongated body (13a) configured to receive the outer profile (11), the locking handle (13) having a proximal locking handle end portion (13b) relative to the pivot end portion (9a) of the inner arm (9) and a distal locking handle end portion (13c), the distal locking handle end portion (13c) being configured to be pivotally attached to the distal outer profile end portion (11c) thereby forming a first pivot connection (7b), wherein the locking handle (13) is configured to pivot about the first pivot connection (7b) relative to the outer profile (11) and the inner arm (9), between a proximal pivot position and a distal pivot position in which the locking handle (13) is pivoted further away from the outer profile (11) than in the proximal pivot position, and a locking structure (15). The locking handle (13) is configured to cause the locking structure (15) to engage with the outer profile (11) and the inner arm (9) to axially interlock the outer profile (11) with the inner arm (9), and wherein the locking handle (13) is configured to move the locking structure (15) from engagement with the outer profile (11) and the inner arm (9) to release the outer profile (11) from axial interlocking with the inner arm (9) when the outer profile (11) is in the proximal position and the locking handle (13) is moved from the distal pivot position towards the proximal pivot position.

A brake system for use with a wheeled device, such as a wheeled person transportation device, such as a wheelchair. The brake system comprises a handle comprising a first portion and a second portion, wherein the first portion is moveably coupled to the second portion; a carrier comprising an internal cavity; a brake actuator for actuating a brake, the brake actuator being arranged within the internal cavity; brake actuator biasing means for applying a biasing force to the brake actuator for biasing the brake actuator to a brake-engaged position; and force-transfer means coupled to the first portion and to the brake actuator such that movement of the first portion towards the second portion causes the brake actuator to move along the internal cavity of the carrier against the biasing force to a brake-disengaged position.

A mobile chair apparatus is described that comprises a drive assembly that preferably includes one or more moveable foot pedals, and drive wheels which rotate in response to rotation of the foot pedals by the mobile chair occupant, and a steering assembly which comprises two steering wheels and at least one tiller, configured such that forward and backward movement of said tiller will translate into movement of both steering wheels, wherein the drive assembly and the steering assembly concurrently enable the mobile chair occupant to propel and steer the mobile chair apparatus without assistance from another person.

This relates to a propulsion attachment for a manual wheelchair and methods of operation. The propulsion attachment can include three wheels, a motor, a gearbox, and a handlebar. The propulsion attachment can attach to the footrest of the wheelchair using a pin. The motor can be located in the rear side of the propulsion attachment and can push the user in a forward direction. Alternatively, the user can manipulate a switch located on the handlebar to allow the propulsion attachment to pull the user in a reverse direction. The propulsion attachment can include a plurality of brakes, where each brake can control one of the wheels. Additionally, the propulsion attachment can operate at variable speeds using the motor and the power from one or both batteries.

Apparatus and method using two couplings connecting a wheelchair to a walker for safely assisting a patient regaining their ability to walk. Physical therapists use the walker to train patients on walking to build strength, endurance, and balance. The couplings provide a fixed gap between the wheelchair and walker and keeps the wheelchair close to the patient. The patient can easily sit in the wheelchair, and the presence of the wheelchair minimizes the risk of falling, allows the patient to rest when fatigued, provides a sense of security, and eliminates a need for an assistance to push the wheelchair behind the patient.
