More Information
Summary:A stair 1 including at least one tread portion 30 and an elevating mechanism 50 by which the tread portion is elevatable to a deployed position in which the tread portion is presented to be stepped on by a person. The stair further includes a pedal 61. The elevating mechanism includes a stop 51e and a striking portion 54b. The striking portion is arranged to move into abutment with the stop when the tread portion is so elevated to its deployed position. The striking portion is also arranged to be driven against the stop by at least a portion of the person's weight. The pedal is pressible to move the striking portion away from the stop. The elevating mechanism is configured such that, when the striking portion is so moved away, depressing the tread portion moves the striking portion further away from the stop.
