Embodiment Construction

[0030] Different embodiments of elastic fastening devices are shown in the drawings. The invention enables the screw fastening to be replaced by elastic fasteners of this type fastened directly to the outer perimeter of the plastic mounting post 30 (a part of the washing tub) passing through the counterweight 20 .

[0031] The device 10 has an inner periphery 1 forming, in a substantially central region, an axial channel 2 into which a mounting post 30 of the washing tub is inserted and which has, for example, a toothed surface. The locking element 4 is used to lock on the plastic surface of the mounting post 30 when the mounting post is inserted through the axial channel 2 .

[0032] The elastic means 10 can be configured to lock at one or several heights on the mounting post 30 . exist Figures 1 to 4 As can be seen in the two embodiments shown in , the locking element 4 is arranged at two different heights, allowing locking at different heights on the mounting post 30, t...

Abstract

Elastic fastening device 10, characterized in that it comprises an inner perimeter 1 that forms an axial passageway 2 in a central zone of the device and an outer perimeter 3, with the device comprising a plurality of locking elements 4 arranged on the inner perimeter 1 and with the outer perimeter 3 comprising at least one elastic support shaped essentially like a laminar section folded over on itself.

Description

technical field [0001] The invention relates to an elastic fastening device for fastening a balance weight to a household appliance, in particular to an elastic fastening device for fastening a balance weight to a washing tub of a washing machine. Background technique [0002] Various fastening systems exist for fastening counterweights to the tubs of washing machines and dishwashers. These connections are always realized mechanically by means of screws, nuts, adhesives, plastically mounted cylindrical expansion elements or the like. In many fastening processes, threaded parts or material applications are employed that create labor costs during assembly. [0003] Some of these systems use elastic connections with elastic spacers, such as in document EP2159314A1, where some solutions combine two systems into one. [0004] Document WO2006 / 064429A1 describes a mechanism with a balance weight connected to an extension and an elastic spacer, said balance weight comprising one o...
