Abstract: What is shown and described is a mobile walking and transport aid device (1) for supporting particularly persons with impaired walking ability, with a chassis (2) with wheels (3, 4) and with two outer lateral supports (5, 6), which are fixed to the chassis (2) as supporting elements for a user of the device (1). According to the invention, a provision is made that the lateral supports (5, 6) are attached to the chassis (2) such that they can be swiveled about a horizontal axis from a first, backwardly tilted position for pushing the walking and transport aid device (1) from behind and/or for supporting the user while walking inside and/or behind the walking and transport aid device (1) and/or for the user to sit on the walking and transport aid device (1) into at least one forwardly tilted position for pulling the walking and transport aid device (1) from the front.

Abstract: An electrically driven single-drive-axis vehicle with a platform for a driver, driven about a common wheel axis, which provides the single-drive-axis to improve its handling and its range of uses. The vehicle includes at least one attachment, the attachment being connected to the single-axle vehicle pivotably about at least one first attachment axis.

Abstract: A handle for a screwdriver-type tool rotatable about a tool axis has a front handle portion having a front end adapted to carry the tool and a rear end formed with a pivot centered on an axis transverse to the tool axis and spaced by a predetermined axial distance from the front-portion front end. A rear handle portion is mounted on the pivot on the front handle portion and is displaceable between a normal-use position generally centered on and extending along the tool axis and a high-torque position extending transverse to the tool axis. The portions have a combined axial length in the normal use position equal to less than twice the overall axial length of the front handle portion.
