Patent number: 8991928Abstract: A constricting member of a chair footrest ring is revealed. The constricting member is mainly a constricting sleeve with a hole mounted on a center thereof. A plurality of tapered-shaped mounting and fixing parts is disposed projectingly on an outer surface of the constricting sleeve, from top to bottom and expanded outward. At least one trench is also formed on the outer surface of the constricting sleeve. A positioning projective ring is projecting from and integrally formed on an outer edge on a top end of the constricting sleeve. The structure is simple so that the manufacturing cost is reduced and the assembling is more convenient and faster.Type: GrantFiled: September 14, 2012Date of Patent: March 31, 2015Inventor: Kun-Yu Hsieh

Patent number: 8646841Abstract: An ergonomic pedestal seat that interacts with the sitter's musculoskeletal system in a way that optimizes their use of gravitational forces is provided. This seat orients a sitter toward an alignment that encourages a balance between gravity's descending force and its ascending counterforce, the ground reaction force. The seat comprises a four-tier seat base, a non-vertical central supporting column and a contoured seat pan. The base has a surface that allows the sitter to sustain a stable alignment and to rock forward or sideward or both, as well as a Lazy Susan mechanism that permits turning. This seat supports the sitter through a range of seated activities, including quiet activities such as meditation and complex tasks requiring reaching, bending and turning. When on this seat sitting becomes a source of pleasure rather than an activity of drudgery.Type: GrantFiled: August 13, 2010Date of Patent: February 11, 2014Inventor: Mary Ann Molnar
