Undercarriage (chassis):
Picture no. 3 NF-Walker 2 undercarriage (chassis) (this picture shows the undercarriage of NF-Walker 2 size S)
The undercarriage has an H-shape. The front axle (12) and rear axle (18) are connected by the main
frame (10). When a user is using the NF-Walker 2, she/he will have one leg at each side of the main
frame (10), between the front axle (12) and the rear axle (18). Having the main frame (10) between
the user’s legs will prevent the user of crossing hers/his legs while using the NF-Walker 2.
The undercarriage has four wheels (8 and 16) with 185mm diameter. The rear wheels (8) are fixed in
direction, and a brake (7) can be activated to prevent the undercarriage from rolling. The front
wheels (16) can freely rotate 360° or be locked in forward direction using the direction lock (15). The
rear wheels (8) are assembled to the rear axle (18) which is having a fixed width. The front wheels
(16) are connected to the front axle (12) which is fixed in width.
