Description

Vacuum cleaner nozzle provided with pivot blocking device {VACUUM CLEANER NOZZLE PROVIDED WITH A PIVOT BLOCKING DEVICE}

The invention relates to the field of vacuum cleaners equipped with a vacuum cleaner nozzle, also called a suction head, which makes it possible to suction dust and waste present on the surface to be cleaned, which can be, for example, tiles, parquet floors or laminate.

The vacuum cleaner nozzle is manufactured in a known manner:

- a body comprising a brush, the brush being provided with a lower surface configured to be oriented towards the surface to be cleaned and a suction opening emerging into the lower surface of the brush,

- a connecting sleeve intended to hold the suction tube of a vacuum cleaner, fluidly connected to the suction port,

- a hinge device mechanically connecting the connecting sleeve to the body, the hinge device defining a first pivot axis extending transversely to the main direction of movement of the vacuum cleaner nozzle, the connecting sleeve being positioned anteroposteriorly and transversely relative to the body; It includes a first pivot connection configured to be tilted centrally, and a second pivot connection defining a second pivot axis and configured to cause the connecting sleeve to be tilted left and right relative to the body and about the second pivot axis.

These vacuum cleaner nozzles may include, for example, a suction tube configured to be connected to a connecting sleeve; a flexible suction pipe connected to a connection endpiece provided on the suction tube; an unfolded configuration hingedly mounted on the suction tube about a hinge axis substantially perpendicular to the longitudinal axis of the suction tube, wherein the gripping handle extends substantially parallel to the suction tube, and the gripping handle and the suction tube are disposed between them. , for example, may be connected to an accessory comprising a gripping handle between the folded configurations defining an angle of approximately 90°.

When the aforementioned vacuum cleaner nozzle is connected to such an accessory and the accessory is in a folded configuration, the connecting sleeve and suction tube extend substantially horizontally and thus allow the user to move the vacuum cleaner nozzle (without the suction tube interfering with such displacement). It can be moved under furniture, for example under a sofa, to clean the area located under this furniture.

However, when the user moves the vacuum cleaner nozzle while the accessory is in the folded configuration, the vacuum cleaner nozzle is unwieldy due to the relative movement between the main body and the connecting sleeve about the second hinge axis, making it difficult to control the vacuum cleaner nozzle. There is a high possibility of causing undesirable lateral displacement. Additionally, such hinges around the second hinge axis are likely to result in unwanted lifting of the vacuum cleaner body when the accessory is in a folded configuration, which is likely to be detrimental to the cleaning effectiveness of the vacuum cleaner nozzle.

The object of the present invention is to improve these shortcomings.

The fundamental technical task of the present invention consists, in particular, in providing a vacuum cleaner nozzle that is simple in structure, economical, ergonomic, and has increased cleaning performance and operability.
