Abstract: A cup supporting device includes a ring having an opening through which a cup can be inserted; two straps secured to the ring in diametrical relation to each other; a hook member secured to the free end of each strap for hanging the cup supporting device from a chair back; a helical coil spring having an upper end secured to the underside of the ring and hanging downwardly from the ring, the helical coil spring being positioned so as to be in axial alignment with the ring so as to restrain sideward movement of the cup and to hold the cup placed therein through the opening in the ring; and a stop bar secured in diametrical relation across the lower end of the helical coil spring for supporting the cup within the helical coil spring.
