A retractable writing instrument that includes a barrel, a writing tip, an actuating mechanism that includes a plurality of parts for extending and retracting the writing tip upon actuation of the actuation member, and a cushioning device enabling a retraction of the writing tip when an excessive pressure is exerted by a user. The cushioning device includes a spring member elastically deformable, which is integrally formed with a movable part of the actuating mechanism, the part being movable relative to the barrel. The spring member has a free end abutting the barrel toward its rear end and has a through hole. A stem extends within the spring member's hole and connects the actuating member to the actuating mechanism.

A writing instrument, which has an inner and outer writing element with separate writing medium reservoirs. The writing elements are coaxially mounted in an outer barrel and axially moveable with respect to one another. A driving mechanism may be actuated to allow a user to selectively extend one writing element. The inner and outer writing elements may have an inner sleeve therebetween to improve, for instance, rigidity of the outer writing element and to prevent contamination of the writing medium reservoirs. An outer sleeve may also be provided over the outer writing element. The outer sleeve can function to hold various components of the outer writing element together, and to allow for clean and easy refill of the outer writing element, especially when the outer writing element is a nib-type writing element with a filler-type reservoir. The writing instrument is designed so that a user can replace the inner and/or outer writing elements when their respective writing medium have been expended.

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.

A writing instrument that includes an ink reservoir and a writing tip fluidly connected to the reservoir and through which the ink comes out during use of the instrument. The reservoir contains, in addition to the ink, grains that are separate and that may have angles and sharp edges of dimensions that are significant relative to an apparent dimension d of the grains.

The invention relates to a writing instrument, comprising a body (2), a lateral button (7) with a first cam (11) and a forwarding mechanism, having a movable member (20) with a first inclined plane (23). The lateral button (7) remains in a release position, in which the first cam faces the first inclined plane and can perform a first tilting movement, during which the first cam cooperates with the first inclined plane. Said button (7) comprises a second cam (12) which is longitudinally displaced from the first cam and the movable member has a bearing (25) which is adjacent to the second inclined plane (26). The second cam (12) is supported on the bearing during the first tilting movement and faces the second ramp at the end of said movement. The button can then perform a second tilting movement, during which the second cam cooperates with the second inclined plane.

The invention relates to a hand-held device for transferring a film of, for example, adhesive, covering, or colored material onto a substrate. The device has a housing accommodating a film supply and an application member longitudinally projecting from the housing. Film extends from the supply at the lower longitudinal side of the application member facing the substrate during the mode of operation to an application edge of the application member running transversely at the front end. The application member is composed of two application member portions movable relative to each other. In order to enhance the movability of the hand-held device, the relative movement is limited by motion stops provided as an integral part at the application member portions.
