Flexible crevice tool for vacuum cleaners

摘要

An accessory tool for a vacuum cleaner comprises an elongated body having a plurality of furrows for imparting flexibility to the accessory tool. The elongated body is further be made of a material that is selected to impart flexibility to the accessory tool so that the longitudinal axis of the elongated portion can be bent about a radius through an angle up to 45° without kinking or breaking in a direction transverse to and laterally of elongated cross-sectional configuration.

主权项

1. An accessory tool for a vacuum cleaner comprising:
a body having an attachment end for attachment to a suction hose and an elongated portion having an exterior surface, a substantially smooth interior surface defining an air flow channel, and a nozzle opening in fluid communication with the air flow channel for ingestion of debris-containing air; and a plurality of spaced furrows formed in the exterior surface transverse to a longitudinal axis of the body, the furrows having a relatively narrow width as compared with the spacing on each side of the furrows; wherein the elongated portion has two spaced, straight side walls joined by a curved upper wall and a curved lower wall which together define a cross-sectional configuration perpendicular to the longitudinal axis; wherein the furrows are shaped and the elongated portion is made of a material that is selected to impart flexibility to the elongated portion transversely to the longitudinal axis; wherein the nozzle opening comprises a rim that lies in a plane at an acute angle to the longitudinal axis of the body; and where the furrows lie in planes that are parallel to the plane of the rim.
