A manual device including a first portion and a second portion. The second portion being at least partially fitted into the first portion and being moveable in translation relative to the first portion. The first portion having a first distal end while the second portion has a second distal end opposite the first distal end. The second portion also includes a locking device designed to prevent the first portion from moving in translation relative to the second portion only when, considered in the direction of gravity. The first distal end is arranged above the second distal end, and the locking device includes a chamber and a ball or equivalent accommodated in the chamber. The chamber is provided only in the second portion.

A hand-held device, in particular a writing instrument, comprising a body, a single carriage carrying a first head and a second head, or a first carriage and a second carriage carrying respectively the first head and the second head, and a blocking device including a cavity and a ball, the ball) blocking the single carriage or the first carriage when the first end is below the second end, such that the first head is blocked and projecting while the second head is retracted, and the ball blocking the single carriage or the second carriage when the first end is above the second end, such that the second head is blocked and projecting while the second first head is retracted.

A hand-held device includes a first portion and a second portion. The first portion is engaged at least in part with the second portion while being movable in translation in an axial direction relative to the second portion. The first portion presents a first distal end while the second portion presents a second distal end opposite from the first distal end in the axial direction. A blocking device is configured to prevent the first portion from moving in translation in the axial direction relative to the second portion only when, considered in the gravity direction, the first distal end is arranged above the second distal end. The blocking device includes a chamber and a ball or the equivalent housed in the chamber.

A handheld implement, configured for example as a writing-instrument, having a shaft that has at least two shaft parts which are releasably connectable together via a plug-in coupling, which have a coupling unit at each front end of the shaft parts. Each coupling unit has a slide that is held immovably in a guide hole open on a face side in the associated shaft part and protrudes beyond the guide hole with a slide portion, the free end of the slide portion is formed as a latching fork that has a latching opening between two fork arms, that the slide portion bears a latching protrusion on its inner side behind the latching fork in the sliding direction, the coupling unit has a guide sleeve that encloses the slide and is guided movably in the guide hole counter to the restoring force of a spring- or rubber-elastic restoring element, and when the front ends, having the coupling units, of two shaft parts are pressed together, the latching fork of one coupling unit is latchable on the latching protrusion of the other coupling unit with at least one of the guide sleeves being pushed back.

A writing, drawing, painting or cosmetic device having at least one honeycomb body formed from a plastic material and/or a composite material consisting of a natural material and a plastic material. The at least one honeycomb body contains a plurality of hollow longitudinal structures that are axially parallel to one another.

The invention relates to an input device 1 for capacitive touch-sensitive displays, wherein the device is a simple pen 11, wherein the simple pen can be sharpened, wherein the device is present as a core, or wherein the device is present as a core with a coating, or wherein the device is present as a core with a casing, or wherein the device comprises a core, a casing and a coating, wherein the core, the casing and/or the coating are configured to be electrically conductive, wherein an element, a contacting element 12 for a tablet/display is formed at one end of the device, and wherein the contacting element is formed as an electrically conductive material.
