20120181494 | TELESCOPIC LIFTING DEVICE WITH SAFETY STRAP - A lifting device with a telescopic pole having at least three successive modules mounted so that the modules can slide vertically with respect to each other. A drive strap transfers movement in order to extend an upper module with respect to an intermediate module when the intermediate module is caused to move with respect to a lower module of the modules. The drive strap is kept taut between two fixation points placed respectively on the lower module and upper modules and pass along a return pulley device mounted on the intermediate module. A safety system is normally maintained in inactive position by tension of the drive strap is automatically released into active locking position to prevent the upper module from continuing to move with respect to the intermediate module if the drive strap breaks. | 07-19-2012 |
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 |
