ABSTRACT:
A roller/foot device (1) comprising a cylindrical outer sleeve (10), a guide sleeve (20) arranged inside the outer sleeve (10), locking sleeve (30) arranged inside the outer sleeve (10), a spring device where one end abuts against the outer sleeve's closed end (13) and the other end abuts against one end portion of the guide sleeve or the locking sleeve and a roller element (41) which is rotatably mounted abutting against the locking sleeve's (20) end portion which is located at the extreme end of the outer sleeve (10). The sleeves comprise ribs which can slide towards each other and cause the roller element (41) to assume different positions in the longitudinal direction of the outer sleeve (10) when the device (1) is subjected to forces. The device (1) can thereby be employed as a roller device with the roller element (41) in an outer position and as a foot device with the roller element (41) in an inner position.
