The engagement rod is movable up and down along the back in correspondence with the pivotable movement of the support rod such that the back is supported at a selected position by engaging the engagement rod is one of the notches.

Abstract: A caster mechanism for a carriage having foot rods a, b includes a stopper mechanism 3 fixedly secured to a lower end of each foot rod. A wheel support mechanism 2 is rotatably positioned below the stopper mechanism, and includes an engagement bracket 1 extending parallel to the stopper mechanism. The engagement bracket has an engagement fitting portion 12 formed at a first end of an arm plate 11 having a predetermined length. The stopper mechanism also has an actuating lever 8 at a first end of a base plate 34 having a predetermined length, which is adapted to turn upwardly and downwardly about an end thereof. An engagement member 7 adapted to turn up and down in operative association with the actuating lever is positioned below the first end of the base plate.

Abstract: An infant restraining chair for installation in a corner or other compact area of a bathroom, for restraining an infant while the infant's guardian makes use of bathroom facilities. A chair supporting and surrounding a substantial portion of an infant's body is mounted on top of a column having a cross-section of a generally triangular shape. Arcuate seat belt portions of substantially rigid construction are maintained in a body of the chair normally in a position retracted into the chair, but are selectably extendable out of the chair body to encircle and restrain an infant seated in the chair. A retraction arrangement utilizes force from gravity constantly to bias the seat belt portions into a retracted position. A mechanical locking arrangement may be provided for locking the seat belt portions in a restraining position.
