  • Patent number: 5335374
    Abstract: A household implement comprises a cup-shaped plunger member contactable with a household surface and a collapsible handle attached to the plunger member. The handle has an outer tubular handle part and an inner tubular handle part telescopingly inserted therein. One end of the inner tubular handle part is fixed to the plunger member, while an opposite end of the inner tubular handle part is disposed inside a first end of the outer tubular handle part. The first end of the outer tubular handle part is provided with an aperture. The household implement further comprises a hollow casing member attached to the outer tubular handle part at the first end thereof. The hollow casing member is larger than the plunger member, so that the casing member can substantially surround the plunger member upon movement of the outer tubular handle part over the first tubular handle part towards the plunger member.

  • Patent number: 5305880
    Abstract: A household implement comprises a tool member including (i) an operative element, (ii) an elongate rod attached at one end to the operative element, and (iii) a bar shaped flange connected to the rod at an end opposite the operative element, the bar extending substantially orthogonally with respect to the rod. The implement additionally comprises a hollow housing having a longitudinal axis, an opening at one end and a hand grip at an opposite end. A first locking mechanism is provided at the end of the housing where the hand grip is located. The first locking mechanism cooperates with the flange, upon a rotation of the tool member from a retracted neutral position, to releasably hold the tool member in a retracted locked position to the housing.
