A walking assist device includes: a pair of right and left handles that are movable back and forth with respect to a frame in accordance with arm swing performed during walk of a user; rails on which the handles are provided and which limit movement of the handles in a movable range in accordance with arm swing performed during the walk of the user; a handle information acquisition unit that acquires information related to movement of the handles; and a control unit that controls a drive unit in accordance with the information from the handle information acquisition unit.

A rollator to aid mobility is described. The rollator comprises an A-frame with two pairs of uprights, each pair of uprights connected by at least one respective hinge to allow each pair of uprights to be folded or pivot front-to-back and a seat disposed between the two pairs of uprights, the seat foldable side-to-side. To fold compactly the rollator comprises an X-shaped cross-linkage comprising four linkage members. A method of manufacturing the rollator is also disclosed. The four linkage members may extend from a respective upright to a central hub underneath the seat. The cross-linkage may fold or pivot at the central hub in both front-to back and side-to-side dimensions when the rollator is folded away.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a pivotable securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame; a wheel coupled to the first and second frames; a brake coupled to the wheel to provide friction to the wheel when actuated; and a tensioner coupled to the brake to adjust cable tension during wheel braking.

The invention relates to a robotic walker (1) including a chassis (10) having a front portion (10a), a rear portion (10b), wheels (11a, 11b, 12) arranged to support the rear portion (10b) and the front portion (10a) of the chassis (10), one of the wheels (11a, 11b, 12) being coupled to a displacement motor (20), the robotic walker (1) including a control module (40) configured to control the displacement motor (20), and to: Determine an indicator of an involuntary movement of a user of the robotic walker (1) that could lead to a fall, based on values generated by one or several sensor(s); Identify a previous position, at the given moment, of at least two wheels (11a, 11b, 12); Transmit a command to stop the robotic walker (1); Transmit a command to move the robotic walker (1) so that it returns to the previous position.

A walking aid vehicle (1) includes: an operation part (3) provided on an upper portion of a vehicle body for grasping by a user in a walking posture; a detector (30) for detecting an operation force applied to the operation part; and an inclination detector (20) for detecting inclination of the vehicle body. When an advance direction inclination detected by the detector is less than threshold, a normal control (100) generates a normal direction torque in the drive motor (40L, 40R) responsive to pushing the operation part (3) forward and generates a reverse direction torque in the drive motor responsive to pulling the operation part rearward, and when the advance direction inclination is equal to or greater than threshold and pushing operation force is detected, a shift to a pull control (110) is made which generates normal direction torque in the drive motor responsive to a pulling operation force.

A walker specialized for use on trails by pushing and walking, rather than riding on, with no drivetrain, along with a method of using the walker on trails is provided. The walker can include a frame, two inline wheels, and a handlebar steering mechanism. The walker can further include a braking mechanism, an elbow rest, an electric motor, and racks and/or carriers for gear.

A method for controlling a robotic walking assistant that includes a wheeled base having one or more wheels, two handles and a foldable seat that are coupled to the wheeled base, includes: detecting whether two hands of a user have held the two handles of the robotic walking assistant; receiving a command from the user to select an operation mode in response to detection of the two hands holding the two handles; controlling the wheeled base to move in response to a walking assistive mode being selected; providing resistance to at least one of the one or more wheels according to selection of the user, in response to a walking training mode being selected; and locking the one or more wheels in response to a static training mode being selected.

The invention discloses a brake cable take-up device of folding mobility aids, comprising a frame, a brake cable, and a cable take-up device, wherein the cable take-up device comprises a first pin shaft, a coil spring, and a second pin shaft; the first pin shaft and the second pin shaft are arranged on the frame with a gap; the coil spring comprises an inner end and an outer end; the inner end is rotatably sleeved on the first pin shaft; the outer end is provided with a pulling ring; the brake cable extends from one end of the frame to the cable take-up device, and is movably wound around the second pin shaft and the pulling ring and then extends to the other end of the frame; the frame comprises a longitudinal pipe, and the lower end of the longitudinal pipe is connected with a horizontal pipe.

An assistive mobility device includes a connecting assembly disposed between two frames of a frame assembly, first wheels, second wheels, a positioning assembly disposed between the frames and the connecting assembly, and a stop assembly disposed on the frame assembly. By engaging at least one locking unit and at least one engagement unit of the positioning assembly together, support rods of the connecting assembly are stably unfolded for further use. When the locking unit leaves the engagement unit, the support rods can be folded up, and respective frame bodies of the frames pivotally connected to respective support bodies thereof can also be collapsed by lying down, thereby reducing the bulk of the folded mobility device. The stop assembly serves to prevent random rotations of the second wheels while folding and unfolding the mobility device. Therefore, the mobility device is more convenient and useful to use.

A convertible, self-propelled, motorized mobility assistance device in a plurality of embodiments is provided, comprising a scooter-like chassis (1400) with support deck (300) portion, a handlebar (700), and at least one removable, interchangeable knee rest (800) or seat attachment (1300); wherein the device is mounted atop and driven by at least three motorized wheels (400, 500) which are connected to a source of power and propulsion (1200), and drive (1100). The device further includes a steering system, braking system, and mechanisms for height-adjustability, comfort, and portability.
