Extension pipe having a joint for vacuum cleaner

Abstract

An extension tube for a vacuum cleaner for providing a sealed passage between a main body of the cleaner and a suction brush, the extension tube having a joint including a curved portion bendable according to a user's desire, the extension tube The pipe device includes: a first extension pipe; a second extension pipe pivotably connected to the first extension pipe; The member has a locking protrusion to selectively engage one of a plurality of locking recesses formed in the first extension tube to selectively restrict pivotal movement of the first and second extension tubes relative to each other. A joint cover connected to one side of the second extension pipe can pivot together with the second extension pipe to seal the connection joint. In a second embodiment, the release handle is connected to a pair of locking members, each locking member having a locking projection to selectively engage one of the plurality of locking recesses.

Description

technical field [0001] The present invention relates generally to vacuum cleaners, and more particularly to an extension tube for a vacuum cleaner having a bendable connection portion that facilitates cleaning the space under various pieces of furniture such as a bed or sofa. Background technique [0002] In general, the vacuum cleaner sucks dirt and dust on the surface to be cleaned together with ambient air using a vacuum suction force generated by a vacuum suction motor provided in the main body of the cleaner. The vacuum cleaner has a channel connecting the cleaner body and a suction brush, wherein the suction brush has air in a flow port sealed to the channel. [0003] Various forms of ducting may be employed depending on the type of vacuum cleaner being operated, and generally, the ducting may comprise a flexible hose for connection to the main body of the vacuum cleaner, an operating handle and an extension tube from the operating handle to the Suction brush. Such a...
