A locking device for a telescoping pole for use with a retractable handle system, the pole having at least one moveable section slideably mounted in a guide member having at least one opening. The locking device includes a body fixed to the movable section, a locking member carried by the body and movable between locking an unlocking positions, a rotatable lever carried by the body and pivotable between a release position, in which relative movement is permitted between the movable section and the guide member, and a blocking position, in which the lever comes to bear on the guide member and exerts a force assuring a transverse immobilization of the moveable section in the guide member. The lever is coupled to the locking member to be displaced toward the blocking position when the locking member is engaged in the opening under the force produced by a restoring element.

1. A locking device for a telescoping pole for use with a retractable handle system, the telescoping pole having at least one moveable section slideably mounted in a guide member having at least one opening, said locking device comprising: a body fixed to the movable section;a locking member carried by said body, said locking member being movable relative to said body between a locking position, in which said locking member engages the opening to lock the movable section in position relative to the guide member, and an unlocking position, in which said locking member is disengaged from the opening to permit the movable section to be displaced relative to the guide member;restoring means coupled to said locking member for urging said locking member into the locking position when said locking member is opposite the opening;a rotatable lever carried by said body and pivotable between a release position, in which relative movement is permitted between the movable section and the guide member, and a blocking position, in which said rotatable lever comes to bear on the guide member and exerts a force assuring a transverse immobilization of the moveable section in the guide member, wherein said rotatable lever is coupled to said locking member to be displaced toward the blocking position when said locking member is engaged in the opening under the force produced by said restoring means. 2. The locking device according to claim 1, wherein said rotatable lever is constructed to not exert any pressure on the guide member when in the release position. 3. The locking device according to claim 2, further comprising an unlocking button coupled to said locking member, said button being operable to displace said locking member in opposition to said restoring means into the unlocking position, and wherein said rotatable lever is displaced toward the release position when said locking member is in the unlocking position. 4. The locking device according to claim 3, wherein: said locking member is mounted for displacement in translation in said body along an axis transverse to the longitudinal dimension of said guide member;said locking member has an inclined surface; andsaid locking device further comprises an actuator that comes to bear on said inclined surface and that is displaceable by operation of said unlocking button. 5. The locking device according to claim 4, wherein said rotatable lever has a free end and said locking member has a lateral groove in which said free end of said rotatable lever engages. 6. The locking device according to claim 5, wherein said rotatable lever is mounted to pivot about an axis, and said rotatable lever has a convex surface extending in proximity to the axis and forming a cam that comes to bear on the guide member when said rotatable lever is displaced with said locking member by said restoring means. 7. A household electric appliance comprising: a wheeled base; a transport handle mounted on at least one telescoping pole composed of at least one moveable section slideably mounted in a guide member having at least one opening, wherein said telescoping pole has a locking device as defined in claim 6. 8. The appliance according to claim 7, wherein said base comprises a steam generator and a wrinkle removal brush. 9. A household electric appliance comprising: a wheeled base; a transport handle mounted on at least one telescoping pole composed of at least one moveable section slideably mounted in a guide member having at least one opening, wherein said telescoping pole has a locking device as defined in claim 1. 10. The appliance according to claim 9, wherein said base comprises a steam generator and a wrinkle removal brush. 11. The locking device according to claim 1, further comprising an unlocking button coupled to said locking member, said button being operable to displace said locking member in opposition to said restoring means into the unlocking position, and wherein said rotatable lever is displaced toward the release position when said locking member is in the unlocking position. 12. The locking device according to claim 11, wherein: said locking member is mounted for displacement in translation in said body along an axis transverse to the longitudinal dimension of said guide member;said locking member has an inclined surface; andsaid locking device further comprises an actuator that comes to bear on said inclined surface and that is displaceable by operation of said unlocking button. 13. The locking device according to claim 1, wherein said rotatable lever has a free end and said locking member has a lateral groove in which said free end of said rotatable lever engages. 14. The locking device according to claim 1, wherein said rotatable lever is mounted to pivot about an axis, and said rotatable lever has a convex surface extending in proximity to the axis and forming a cam that comes to bear on the guide member when said rotatable lever is displaced with said locking member by said restoring means.
