The invention describes a releasable wheel mount system for a rollator comprising a wheel axel (1) fastened to a frame (2) comprising a groove (3) near an outer end of the wheel axel (1) and a circular sloped gliding surface (25) at the outer end. The system further comprises a release trigger (4) engaging the groove (4) by means a locking shape (5) locking the release trigger (4) and wheel axel (1) to each other, and releasing the release trigger (4) from the wheel axel (1) a releasing shape (6). The system further comprises a housing (7) with a central cylinder (8) with a cavity accommodating the wheel axel (1), an outer (9) and inner (10) rim stopper, and a trigger cavity (11) accommodating the release trigger, thus locking the release trigger (4) and housing (7) to each other and to the wheel axel.

This is a mobility aid for disabled persons, including a front frame, a rear frame, and a handle frame. The front frame comprises two front legs having front wheels at the bottom ends thereof. The rear frame is attached to the front frame and includes a saddle seat and a rear leg having a rear wheel attached thereto. The handle frame includes a handle horizontal tube and a vertical handle member depending therefrom. The vertical handle member is attached to the front frame. The handle horizontal tube includes an elbow support at each end and a hand rest support plate having a pair of hand rest spheres. A patient can sit on the saddle seat with their elbow resting on the elbow support so that some or most of their body weight is supported by the saddle and elbow support, while the feet can walk freely.

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 adapted for attachment to a wheelchair may be used to assist a user with walking while retaining the wheelchair in close proximity behind the user for use when the user needs to sit. The walker may be removably attached to the frame of the wheelchair for easy exchange of use from one wheelchair to another. A pivotable, removably attachable gate between two lateral frame members may allow for the walker to be manipulated from a walking position to a stored position. The gate may include an extendable width to allow for use with wheelchairs of different widths. A frame of the walker may be extendably attached to the wheelchair, thereby allowing the user to extend and retract the walker between the walking position and the stored position.

A personal mobility system with multiple adjustments is presented. The personal mobility system may comprise one or more elastic stabilizer mechanisms. The adjustments may comprise a telescoping adjustment system for multiple handles, to adjust height and position of handles. The personal mobility system presents handles at a variety of positions, and of different types, to assist a user in moving from sitting to standing to walking, and to and from other positions, and presents a seat. The personal mobility system with elastic stabilizer mechanisms stabilizes the system against tipping over, improving user safety by reducing the occurrence of tips and falls. The elastic stabilizer mechanisms may be engaged by all handles and grip surfaces, or by a subset thereof, of the personal mobility system when a user begins to tip. The personal mobility system presents improvements in folding, convenience, and useability.
