Abstract: A frictional clutch for a hand-held device for transferring a film from a backing tape onto a substrate comprises a first main member having a cylindrical element coaxially protruding into a circular center opening of a second main member. The first and second main member are supported such that they can carry out a relative rotational movement. The second main member include coaxial tensioning elements for holding and pre-tensioning an elastic ring guided around the tensioning elements. The tensioning elements are geometrically arranged such that the ring is exposed in the form of at least one secant-shaped leg in the center opening. The secant-shaped leg of the ring is biased radially outwards when the cylindrical element of the first main member is inserted into the center opening of the second member in order to produce a frictional force between the ring and the circumferential wall of the cylindrical element.

Abstract: A writing instrument that includes a body extending along a central axis between a front end provided with a writing tip and a rear end, the body presenting a grip zone and comprising at least first and second elements that are assembled together, and a tubular grip sleeve covering the grip zone at least in part. The grip sleeve presents at least one projection extending towards the central axis, and the first and second body elements define a housing adapted to receive the projection of the sleeve, the projection being pinched in the housing by the first and second assembled-together elements.

Abstract: A writing implement mechanism comprises includes a tubular first element (10) having a central axis and including first and second walls (12, 14) presenting that include respective first and second edges (16, 18) defining a guide (20) extending longitudinally in a direction that is inclined relative to the central axis between a first end and a second end. The mechanism further comprises includes a second element (26) adapted to slide along the first element (10) and including a nib (28) sliding in the guide (20). The second wall (14) is offset towards the central axis relative to the first wall (12) in a direction that is radial relative to said the central axis (Z).
