Patent number: 8840087Abstract: 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.Type: GrantFiled: January 24, 2012Date of Patent: September 23, 2014Assignee: Talbot Decoupage EmboutissageInventor: Francois-Xavier Guyard

Patent number: 8807534Abstract: 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.Type: GrantFiled: January 24, 2012Date of Patent: August 19, 2014Assignee: Talbot Decoupage EmboutissageInventor: Francois-Xavier Guyard

Patent number: 8695945Abstract: A hand winch including a winding roll, a flexible elongated member, a shaft connected to the winding roll, a friction brake including a brake disk and a gear element engaging the winding roll and mounted on the shaft. The gear element has a release position and a brake position in which the gear element enters into frictional contact with the brake disk, generating a braking torque resisting winding off the flexible elongated member. Friction means is provided between the shaft and the gear element for generating a frictional resistance therebetween such that, if a driving force acting on the gear element does not overcome the frictional resistance established by the friction means, the gear element drives the shaft through friction means. However, if the driving force between the shaft and the gear element overcomes the frictional resistance, relative movement between the gear element and the shaft occurs.Type: GrantFiled: August 12, 2010Date of Patent: April 15, 2014Inventor: Francois-Xavier Guyard
