254095000 | RACK AND PINION | 6 |
20080210915 | Jack bar with extendable tubes and fixturing mechanism - A jack bar includes an outer tube, an inner tube and a positioner tube coaxially located. The positioner tube is extendable to adjust a length to the jack bar in use while enabling the jack bar to be retracted for storage. The jack bar further includes a clamp configured to receive tubes of various shapes. The clamp is further configured to prevent twisting or turning of clamped tubes. | 09-04-2008 |
20110253953 | RACK AND PINION MECHANISM, VACUUM PROCESSING APPARATUS, METHOD OF DRIVING AND CONTROLLING RACK AND PINION MECHANISM, DRIVE CONTROL PROGRAM, AND RECORDING MEDIUM - The present invention provides a rack and pinion mechanism which avoids collision between respective tooth tops of a rack gear and a pinion gear due to a phase shift between the rack gear and the pinion gear with a simple mechanism and meshes the rack gear and the pinion gear smoothly. | 10-20-2011 |

20120181490 | Telescopic Rack-And-Pinion Lifting Device - A lifting device with a telescopic pole that has a lower module and an upper module which is mounted in vertical sliding relation with respect to the lower module and which is movable along the pole by a crank handle through a rack-and-pinion drive mechanism. A non-return locking device is automatically implemented by friction coupling mechanism with a drive pinion of the drive mechanism driven by rotating the crank handle for more than one complete turn. | 07-19-2012 |
20130327997 | Automatically Extensible Telescopic Apparatus - An automatic extensible telescopic apparatus includes an internal tube inserted in an external tube. A positioning unit includes a ferrule, two fins, an axle, a toothed wheel and a first detent. The ferrule is provided on the external tube. The fins extend from the ferrule. The axle is supported on the fins. The toothed wheel is supported on the axle and includes teeth for insertion in recesses defined in the internal tube. The first detent is supported on the fins for engagement with the toothed wheel. A handle includes two leaves and a second detent. The leaves are placed between the fins and supported on the axle. The second detent is supported on the leaves for engagement with the toothed wheel. An extending unit is connected to the axle so that the extending unit rotates the toothed wheel via the axle, thus extending the internal tube from the external tube. | 12-12-2013 |
