Abstract
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 writing instrument comprising:
- a first portion and a second portion, the second portion being at least partially fitted into the first portion and being moveable in an axial direction relative to the first portion;
- the first portion includes a first distal end while the second portion includes a second distal end opposite the first distal end, and a lock;
- the first distal end is provided with a first head that includes a writing tip or a nib;
- the second distal end is provided with a second head;
- wherein the lock is movable between a first configuration and a second configuration by gravity only,
- wherein in the first configuration, the lock is configured to permit relative axial movement between the first portion and the second portion, and in the second configuration, the lock is configured to prevent relative axial movement between the first portion and the second portion;
- wherein the first head includes a retraction mechanism, the retraction mechanism facilitates a retractable movement of the first head to protrude either outside or extend inside of the writing instrument.
A writing instrument comprising:
- a first portion and a second portion, the second portion being at least partially fitted into the first portion and being moveable in an axial direction relative to the first portion;
- the first portion includes a first distal end while the second portion includes a second distal end opposite the first distal end, and a lock;
- the first distal end includes a writing tip or a nib;
- wherein, when the first distal end is arranged above the second distal end in a direction of gravity, the lock is configured to:
- prevent relative axial movement between first portion and the second portion when the writing tip or nib is in a retracted position;
- and
- allow relative axial movement between the first portion and the second portion when writing tip or nib is in an extended position.
A writing instrument comprising:
- a first portion and a second portion, the second portion being at least partially fitted into the first portion and being moveable in an axial direction relative to the first portion;
- the first portion includes a first distal end while the second portion includes a second distal end opposite the first distal end, and a lock;
- the first distal end includes a writing tip or a nib;
- wherein the lock is movable between a first configuration and a second configuration, the lock including a chamber and a movable element disposed in the chamber, wherein the chamber is positioned within only the second portion,
- wherein in the first configuration, the lock is configured to permit relative axial movement between the first portion and the second portion, and in the second configuration, the lock is configured to prevent relative axial movement between the first portion and the second portion;
- wherein the lock is configured to move between the first configuration and the second configuration by inversion of the writing instrument.
