US Patent:

58333070, Nov 10, 1998

Filed:

Jul 25, 1997

Appl. No.:

8/900635

Inventors:

Thomas R. Leach - Midway TN
Mark S. Williams - Bluff City TN

International Classification:

A47C 1300

US Classification:

297133

Abstract:

A rocker conversion unit for a molded, stackable lawn-type chair. The rocker conversion unit has an upwardly curved channel shaped rocker having elongated base means adapted to provide the bottom of said rocker and to contact and rock on lawn or other supporting surface, first and second side means integrally connected to opposite edges of said base means and extending upwardly therefrom along substantially the full length thereof. The channel has a substantially uniform side-to-side width and base-to-shoulder height throughout its length and foot retainers to engage the lateral foot segment of a mold lawn chair in a tight frictional fit that locks the chair leg into the channel and stabilizes the rocker on the chair leg.

Abstract:

A digital gas sensing system comprises a plurality of satellite subassembly units each including a central processing unit (CPU) and a plurality of "intelligent" sensors connected to the satellite subassembly units by a single pair of leads. The satellite subassembly units communicate to the sensors in a code having a predetermined number of digital bits. Each sensor has internal "intelligence" and recognizes its own unique address and responds to the satellite subassembly unit in a predetermined code that varies from the satellite subassembly unit code by one parity bit. This arrangement makes it possible for other sensors to distinguish between transmissions from the satellite subassembly unit and transmissions from other sensors. The net result is that the system is able to operate very reliably using only two leads to connect all of the sensors to the satellite sub subassembly unit thereby greatly reducing the wiring and installation costs of the system. To further expand the potential of the system it is also possible to link a plurality of satellite subassembly units together to a single master control unit.

International Classification:

A47C 1300

US Classification:

297133

Abstract:

A rocker conversion unit for affixing rockers to an ordinary molded plastic lawn chair, wherein the unit has an upwardly curved channel shaped rocker the sides of which have an inwardly extending lip providing a first shoulder downwardly facing and adapted to provide a stop for preventing withdrawal of structure upwardly from the channel, a block slidable within the channel and having a second and upwardly facing shoulder extending along each side edge thereof and adapted to engage the first shoulder and be stopped in its upward movement thereby, the block having a height dimension from its bottom to its second shoulder which is less than the base-to-shoulder height dimension of the channel to provide a space in which a lateral foot segment of a molded lawn chair leg can be positioned, and wherein the block further has a manually operable pressure portion adapted to simultaneously force a lower portion of the block downwardly against the foot segment and to force the second shoulder upwardly against the first shoulder whereby the foot segment is rigidly, frictionally locked in position against the bottom of the channel and the rocker is stabilized on the chair.
