DE10156420B4 - Device for attaching a counterweight to a domestic appliance - Google Patents

Abstract

The aim of the invention is to provide a device, which permits a counterweight to be securely and durably fixed at relatively low cost, for example on a household appliance, in particular a dishwasher or a kitchen range. Said aim is achieved, whereby a device is provided for fixing a counterweight, in which said counterweight (1) is arranged in a drawer-type recess (2), provided in a base and designed, such that the retention force, which is necessary for fixing, is substantially generated by deformable fixing lugs (3).

Description

The invention relates to a device for attaching a counterweight to a domestic appliance, in particular Dishwasher or Stove.

For household appliances, especially dishwashers or Flocks with a front mounted to a horizontal Axis pivoting door the problem arises that when loading or Unloading the dishwasher or the stove a lower basket or a push car from the central body of the household appliance is pushed out and the static load on the household appliance changes significantly.

For free-standing devices that are neither under one Worktop are still fixed in a cabinet arrangement hence the risk that when loading or unloading a dishwasher on the open door the dishwasher's lower basket is in danger of toppling over a stove with a corresponding push car can also tilt it threatening.

To avoid such a danger becomes conventional a counterweight in the rear area of the household appliance arranged, which is designed so that at a maximum expected Loading the dishwasher or cooker a corresponding compensation load is provided, which effectively prevents the household appliance from tipping over.

From the DE 38 29 381 A1 is known a household appliance, in particular a dishwasher or stove, which has a counterweight in the rear area. This balance weight, which is expediently made of an artificial stone, for example concrete, is fixed by means of holding devices on the assembly floor or assembly frame, in particular using screws. To ensure a secure fixation, the in DE 38 29 381 A1 In addition to the counterweight, the proposed device requires at least six further individual parts, namely two clamping brackets or brackets and four fastening screws.

For the assembly of the in DE 38 29 381 A1 The described counterweight also requires several work steps, since the clamping brackets or brackets have to undergo different deformations after being punched out of the corresponding sheets in order to have the appropriate dimensions and shapes.

Has been a disadvantage of this Design and fixation of the balance weight and at Manufacturing of the parts proved that in addition to the high number of parts a long installation period, as well as a variety of cost-intensive Tools are necessary. In addition to these economic disadvantages this known device has the disadvantage that already the loss of just one screw, the secure fixation of the counterweight.

Object of the present invention it is therefore to provide a device that allows a balance weight with relatively little effort safely and permanently on a household appliance, in particular on a dishwasher or to fix the stove.

This object is achieved by the device according to the invention with the features according to claim 1 solved. Advantageous developments of the present invention are in marked the subclaims.

In the device according to the invention to attach a balance weight is the balance weight arranged in a compartment-like recess in a mounting base and the holding force necessary for fastening becomes essentially deformable Holding claws made on the mounting base, the holding claws after the introduction of the Balance weight are permanently deformed so that the balance weight over a Form-locking connection is held.

The counterweight is advantageously designed in the form of a bar and the holding claws made of plastic, preferably made of a thermoplastic.

In a preferred embodiment of the present invention are the holding claws and the like One-story recess connected to the mounting base so that this compartment-like recess already during the manufacture of the preferably made of plastic mounting base becomes.

The holding claws are expediently bar-like educated.

Are advantageously on the bar-shaped balance weight at least two step-like paragraphs trained, in the projection of the deformed holding claws after the introduction of the bar-shaped Balance weight in the compartment-shaped Engage the recess.

They are preferably laid out like bars trained claws during of the deformation process to the projection of the shoulder of the bar-shaped balance weight and then remain there in such a way that the bar-shaped balance weight after Completion of the assembly essentially can no longer be moved can.

A preferred embodiment of the present invention is described below with reference to Drawings explained in more detail. Show it:

• 1 a schematic plan view of the bar-shaped balance weight and the compartment-like recess,
• 2 : a side view of the bar-shaped balance weight without a special recess,
• 3 a sectional view through the introduced in the compartment-like balance weight and
• 4 is a schematic side view of the compartment-like recess formed by the mounting base.

As in 1 shown, the balance weight fits 1 in the compartment-like recess 2 , which is integrated in a mounting base, for example a dishwasher. The balance weight is preferably 1 made of artificial stone, such as concrete, so that when arranging the compartment-like recess 2 A maximum leverage is generated in the rear area of the mounting base, which results in a maximum compensation function. The balance weight 1 is like in 2 schematically shown, advantageously formed bar-shaped, so that the production of the bar-shaped balance weight 1 can be accomplished inexpensively and with little effort.

After inserting the balance weight 1 in the compartment-like recess 2 becomes the locking claw 3 deformed with a designated tool (not shown) so that the inside of the latch-like holding claw 3 on the paragraph 4 of the bar-shaped balance weight 1 rests and so a positive connection with the bar-shaped balance weight 1 forms. The choice of material for the mounting base is also suitable for the latch-like holding claw 3 selected a thermoplastic material that remains in its end position after deformation and thus secure and permanent fixation of the bar-shaped counterweight 1 guaranteed.

As in 4 shown, can with the dimensioning of the bolt-like holding claw 3 achieved that, even when material aging is taken into account, the bar-shaped balance weight is securely and reliably fixed for a long time 1 can be guaranteed.
