Abstract

An electrical vacuum cleaner, including a vacuum cleaner housing, a suction tube nozzle unit, a suction hose, a suction tube and a suction nozzle, and a retaining arrangement for the suction tube nozzle unit which is provided on the vacuum cleaner housing, the retaining arrangement including a pivotable retaining clip for the suction tube and a retaining recess for a hook mounted on at least one of the suction tube and the suction nozzle, a spring arm movably mounted on an inner wall of the vacuum cleaner housing, the spring arm being hinged, at one end, to the retaining clip, its other end being operatively connectable to the hook in the region of the retaining recess, and a resiliently deformable holder mounted on the spring arm substantially at right angles to a direction of movement, the spring arm and the holder having a recoil force which is less than a force exerted by the hook on the spring arm.

Claims

1. A holder for a suction tube nozzle unit of an electrical vacuum cleaner having a vacuum cleaner housing, the suction tube nozzle unit including a suction hose, a suction tube and a suction nozzle, the holder comprising:

a pivotable retaining clip for the suction tube articulated to the housing;

a hook mounted on one of the suction tube and the suction nozzle;

a recess formed in the housing so as to accept said hook;

a spring arm (10) movably mounted on an inner wall (9) of the vacuum cleaner housing (4), the spring arm (10) having a first end (11) hinged to the retaining clip (8), and a second end (12) operatively engageable with and movable by the hook (7) in the retaining recess (6) so that engagement of the hook with the second end of the spring arm moves the spring arm so as to cause the first end of the spring arm to pull down on said pivotable retaining clip and pivot said clip into a position perpendicular to the wall of the housing; and

resiliently deformable connecting arms (17) mounted on the spring arm (10) substantially at right angles to a direction of movement of the spring arm parallel to the inner wall of the housing along an axis running between the first end and second end of the spring arm, the connecting arms (17) having ends attached to the housing so that a tensile force is generated in the holder connecting arms (17) when the spring arm (10) is engaged and moved by the hook (7), the spring arm (10) and the connecting arms (17) having a recoil force which is less than a force exertable by the hook (7) on the spring arm (10), said recoil force causing said spring arm to move, when said hook is disengaged from said second end of said spring arm, so that said spring arm pushes upon on said retaining clip and pivots said clip into a position parallel to the housing wall.

2. A holder according to claim 1, wherein the spring arm (10) is a one-piece member consisting of two plates (15 and 16) at its ends, separated by at least one spring (13).

3. A holder according to claim 1, wherein the spring arm (10) and connecting arms (17) are formed as one piece.

4. A holder according to claim 1, wherein the spring arm (10) is bent at its second end (12) in the region of the retaining recess (6), so that the bend second end (12) of the spring arm (10) engages in the retaining recess (6), a press key (18) being formed on the bend second end (12).
