A manual wheelchair including a collapsible frame having a first lateral member that is connected to first and second braces at their respective first ends. A drive wheel axel extends along a first axis of rotation and engages a drive wheel, the first brace, and a portion of a transmission. A push rim axel extends along a second axis of rotation and engages a push rim wheel, the second brace, and a portion of the transmission, which transmits rotation of the push rim to rotation of the drive wheel. The collapsible frame additionally includes a second lateral member that is connected to the first and second braces as their respective second ends. The first and second braces are configured to release the second lateral member to collapse the manual wheelchair.

The specification relates to a mobile exerciser. The mobile exerciser can include a mobile exerciser frame; a foot rest assembly attached to the mobile exerciser frame having a working position and a stored position; and a pedal assembly attached to the mobile exerciser frame having a working position and a stored position. The mobile exerciser can be converted from a push mode to a pedal mode by moving the foot rest assembly into a stored position and the pedal assembly into a working position and the mobile exerciser can be converted from a pedal mode to a push mode by moving the foot rest assembly into a working position and the pedal assembly into a stored position.

The invention relates to an insert for connecting an electrical connector to a wall (9) and to a corresponding method. The insert comprises an electrically conductive bolt (1) having a head (3), which extends along a first longitudinal axis (I), and a shaft (4), which is provided with at least one connecting means (5), and a ring (2), which has a through-opening (7) and extends along a second longitudinal axis (II). The head (3) comprises an outer contour which, at least in regions, is produced by the rotation about the first longitudinal axis (I) of a first line (L1), which is curved with a first radius (R1) and spaced apart from the first longitudinal axis (1). The through-opening (7) comprises an inner contour which, at least in regions, is produced by the rotation about the second longitudinal axis (II) of a second line (L2), which is curved with a second radius (R2) and spaced apart from the second longitudinal axis (II).

The present disclosure describes a system and method for a providing an assistive driving force to a wheelchair.

Wheelchair drive boost apparatuses, drive assisted wheelchairs, and wheelchair drive boost systems are disclosed. A wheelchair drive boost apparatus includes a housing, a drive wheel including a drive axis that is movable with respect to the housing, a drive lever that engages with the drive wheel to cause the drive wheel to rotate, a transmission that couples the drive lever to the drive wheel, and an engager having a first position and a second position. The engager is configured to move the drive axis with respect to the housing.

A retrofitable drive assembly attaches and detaches quickly, easily, and reversibly from a conventional, manually powered wheelchair and is employed to convert the manually powered wheelchair into an electrically powered wheelchair. The drive assembly includes a plurality of wheel troughs, each adjustably sizeable to receive therein a rear push wheel of the manually powered wheelchair, regardless of the wheelchair's size and its rear push wheels' dimensions. In addition, the drive assembly includes two drive wheels positioned towards a front end of the drive assembly and a single caster-wheel assembly positioned towards a rear end of the drive assembly.
