BENDABLE EXTENSION PIPE FOR VACUUM CLEANER (VERSIONS)

FIELD: mechanical engineering. ^ SUBSTANCE: bendable extension pipe has at least two parts which may be rotated relative to each other in accordance with user's selection. Extension pipe has first part and second part, which are pivotally connected to one another, and unlocking handle adapted for selective fixing of first and second parts of extension pipe in predetermined position. In order to unlock first and second parts of extension pipe, which are locked relative to one another in predetermined position, user lowers unlocking handle by pressing said handle. According to second version, unlocking handle closes at least part of circumferential peripheral surface of first part of pipe and is equipped with at least one lever made integral therewith at one end thereof. Lever is selectively fixed upon rotation of second part of extension pipe. During operation of apparatus, user may bend extension pipe simply by lowering of unlocking handle without necessity of leaning. ^ EFFECT: convenient use and increased efficiency. ^ 13 cl, 5 dwg
