Title:
FLOOR FITNESS DEVICE WITH VARIABLE STEP HEIGHT
Document Type and Number:
Japanese Patent JPH06339545
Kind Code:
A
Abstract:
PURPOSE: To adjust a large angle of inclination under meeting every requirements for safety technique by fitting a circular arc-like supporting surface formed in a sidewall of a footboard to a supporting surface of lower structure members. CONSTITUTION: A floor fitness device 1 has an upper footboard 2 and a plurality of lower structure members 3. A circular arc-like supporting surface 5 of the footboard 2 which has a radius 7 of the same radius 12 of the lower structure member 3 is made as a circular arc part having a span of a circular arc L shorter than that of a circular arc L'. A circular locus 10 is drawn by the radius 7 and the center 8 at a supporting point 9 which located at an extreme outside and is the same as each area. The radius 7 of the supporting surface is held within the uppermost member of the lower structure members 3 for not being inclined by the lower structure members 3. Since there is the only terminal point of the sidewall 4 at an radius terminal 14 of the supporting surface 5, a full arc span L of the supporting surface 5 is held on the supporting surface 6 of the lower structure members 3 by configuration connection.
