Definitions

  • the invention relates to a manual device equipped with a device for locking in translation of one part relative to another as a function of the relative position of the two parts considered in the direction of gravity.
  • a manual device can be a writing instrument, but not exclusively.
  • Manual devices having a first mobile part relative to a second part, such as for example the rear part carrying a rubber of a mechanical pencil which is movable relative to the front part of the mechanical pencil, see for example FR-A- 1100962 , which discloses such a device.
  • the second part when we want to use the second part, for example when we want to erase, the second part remains mobile relative to the first part, which can cause the user to move the second part relative to the first part inadvertently, causing thus for example to advance the mine of the mechanical pencil while it is erasing.
  • Such an operation is generally not intended. There is therefore a need in this direction.
  • One embodiment relates to a manual device comprising a first part and a second part, the first part being at least partly fitted with the second part while being movable in translation in an axial direction relative to the second part (and vice versa) , the first part having a first distal end while the second part has a second distal end opposite the first distal end in the axial direction, and a locking device configured to block the translation in the axial direction of the first part with respect to to the second part (and vice versa) only when, considered according to the direction of gravity, the first distal end is disposed below the second distal end, the locking device comprising a chamber and a ball or equivalent housed in the chamber .
  • first part can be fitted in whole or in part in the second part or, conversely, the second part is fitted in whole or in part in the first part.
  • press-in direction of the first part with the second part corresponds to the axial direction.
  • each part can be formed from one and the same part, or from several parts assembled together.
  • displacement / translation / sliding of the first part relative to the second part is obviously meant the relative displacement / translation / sliding of the first part relative to the second part and vice versa. (ie the relative displacement / translation / sliding of the second part compared to the first part).
  • direction of gravity is understood of course the direction of the Newtonian gravitational acceleration created by the Earth or, more generally by the body or the star on which the manual device is used.
  • ball or equivalent any solid element of any shape, movable in the chamber, and capable of moving in the chamber under the effect of gravity relative to the walls delimiting the cavity of the chamber.
  • ball is meant “ball or equivalent”.
  • shape of the chamber is arbitrary, and can be simple or complex.
  • the locking device allows relative translation in the direction axial of the first part with respect to the second part while when the first distal end is above the second distal end, the locking device blocks the relative translation in the axial direction of the first part with respect to the second part .
  • the relative position "above” or “below” of the first and second distal ends is considered according to the direction of gravity.
  • the locking device is a gravity locking device.
  • the locking device blocks, automatically and solely thanks to the effects of the gravity, the translation in the axial direction of the first part with respect to the second part while in a second state where, considered according to the direction of gravity, the first distal end is disposed below the second distal end, the blocking device allows, automatically and solely by virtue of the effects of gravity, the translation in the axial direction of the first part relative to the second part.

  • the manual device also has a second configuration where the first part cannot be moved in the axial direction with respect to the second part thanks to the blocking device, for example, but not necessarily, to block said mechanism to bring in / out the head, this configuration corresponding to the configuration where the first distal end is above the second distal end.
  • the blocking operated by the blocking device can be a strict blocking without axial play between the first and the second part, a blocking with axial play between the first part and the second part, or even a limitation of the relative axial stroke. between the first part and the second part (ie a blockage with a relatively large play).
  • the ball of the blocking device cooperates with the first part and the second part so as to block their relative movements in translation in the axial direction while in the first configuration the ball does not cooperate with the first part and the second part so as to block their relative movements in translation in the axial direction.
  • the ball in the first configuration, the ball is in a so-called free position (ie position where the locking device leaves the first part free in axial translation with respect to the second part) while in the second configuration, the ball is in a so-called blocking position (ie position where the blocking device blocks the first part in axial translation relative to the second part).
  • the locking device is carried out in the second configuration independently of any configuration of any any other element / mechanism of the manual device.
