  • Such an unlocking member is generally located opposite the articulation device, and therefore in a lower part of the vacuum cleaner duct. As a result, the unlocking member is barely visible to a user handling the vacuum cleaner conduit, which may make it difficult for certain users to manipulate the unlocking member and therefore cause the first and second rigid conduit parts to move. in the folded configuration.
  • the present invention aims to remedy all or part of these drawbacks.
  • the technical problem underlying the invention consists in particular of providing a vacuum cleaner duct which is simple, reliable and ergonomic in structure.
  • the unlocking member comprises two lateral gripping parts, such as lateral gripping lugs for example, which are located on either side of one of the first and second rigid conduit parts and which each comprise at least one gripping surface, each of the lateral gripping parts being intersected by a plane which is parallel to the articulation axis and which contains the central longitudinal axis of the vacuum cleaner duct in the unfolded configuration of the first and second rigid duct parts.
  • the two lateral gripping parts extend beyond a plane which is parallel to the hinge axis and which contains the central longitudinal axis of the vacuum cleaner duct in the unfolded configuration of the first and second rigid conduit parts.
  • Such a configuration of the two lateral gripping parts allows a user to be able to view, and therefore operate, the unlocking member more easily.
  • unlocking member allows a user to move the unlocking member into the unlocking position either by exerting pressure on a central part of the unlocking member which is diametrically opposite to the device. articulation, or by pulling on at least one of the two lateral gripping parts.
  • the action of pulling simultaneously on the two lateral gripping parts is advantageously done with the fingers of one hand, for example the thumb and index finger or the thumb and middle finger.
  • the unlocking member according to the present invention allows a user to easily move the first and second rigid conduit parts in the folded configuration, and therefore gives increased ergonomics to the vacuum cleaner conduit according to the present invention.

  • the user can move the locking member towards the release position by pulling on at least one of the two lateral gripping parts.
  • the user can initiate a pivoting of the first part of rigid conduit relative to the second part of rigid conduit towards the folded configuration in which the first and second parts of rigid conduit define between them an angle less than 180°.
  • the user can push the first or second part of rigid conduit by for example bearing on an exterior surface of the first or second part of rigid conduit located on the same side of the vacuum cleaner conduit as the articulation device.
  • the action of pulling the two lateral gripping parts towards the hinge pin, to move the locking member towards the release position can be done for example with the thumb and index finger.

  • Such a configuration of the unlocking member further promotes the manipulation of the unlocking member, while conferring a greater movement stroke, namely a greater clearance, of the unlocking member during its movements between the positions rest and unlocking. Indeed, if the connecting part extended to the end of each of the lateral gripping parts located opposite the locking member, the connecting part would abut against an external wall of one of the first and second rigid conduit parts after only a short stroke of movement of the unlocking member.
