Definitions

  • the invention relates to a counterweight for washing machines or the like.
  • a base body made of concrete, which can be reinforced by an embedded reinforcing part which extends essentially over the length of the counterweight and with at least one connecting element connected to the reinforcing part for fastening a tub.
  • a generic balance weight (DE-GM 78 27 714) has a base body in which a flange is embedded as a reinforcing part. This has as connection element an annular edge extending radially outward from the base body.
  • connection element an annular edge extending radially outward from the base body.
  • an outer profile is provided which partially covers an edge of the tub and the edge of the flange and clamps the two edges together.
  • the use of an outer ring increases the number of parts to be manufactured and the assembly effort when attaching the balance weight to the tub.
  • This type of attachment also stands in the way of at least partially automating the assembly of the balance weights with the tub.
  • the invention has for its object to form a generic balance weight so that it can be easily connected to the tub without using additional components.
  • connection element for a screw connection has a through opening and this has an area adjacent to it outside the concrete.
  • connection element for a screw connection has a through opening
  • counterweights can be connected to a tub in a simple and at least partially automated manner. Due to the fact that an area lying outside the concrete is adjacent to the through opening, the screw connection with the tub can be made directly via connection elements substantially without reducing the mass and the rigidity of the balance weight. Because in the area of Attachment no concrete is present, at least local crack formation in the base body due to compressive forces acting on the concrete is avoided.
  • a tab can be connected to the reinforcing part as a connecting element.
  • the stiffening effect of the reinforcing parts can be increased by, for example by welding, tabs which can be connected to reinforcing parts such as, for example, monier iron, and at the same time the connecting elements can be produced in a simple manner.
  • a substantially U-shaped extension is formed as a connecting element in the reinforcing part.
  • Connection elements are thereby particularly easy to manufacture, for example, by appropriate shaping of the iron.
  • the stiffness of reinforcement parts can be increased at the same time by means of U-shaped approaches.
  • an elastic bushing can be used for an elastic fastening in a through opening.
  • the connection of balancing weights with tubs can be made flexible in a simple manner. This is particularly expedient if the number of connection elements provided on a balance weight can lead to a statically overdetermined attachment to the tub.
  • fastenings and tension and pressure peaks resulting therefrom can be avoided in subsequent areas of the connecting elements, reinforcing parts and the base body. This also prevents cracking in the base body.
  • the through opening is formed in a tab which is resiliently connected to a tab. This can be achieved in a particularly simple manner without additional components and de associated assembly work, an elastic attachment of the balance weights to tubs.
  • the base body is formed in a closed ring.
  • Such basic bodies are easy to manufacture. Because all balance weights for a tub are made in one piece, they are also particularly simple and can be connected to the tub in an at least partially automated manner. Furthermore, the closed ring-shaped design of the base body stiffens the region of the tub adjacent to it.
  • balance weight has an incompletely shown base body 3.
  • This consists of a concrete that can be produced with relatively little water and has a relatively smooth surface, which after forming the Base body, for example by casting, does not have to be reworked.
  • a reinforcing iron 5 is embedded in the base body 3 as a reinforcing part. This extends essentially over the length of the base body 3, which can be formed, for example, in a closed ring. Closed ring-shaped base bodies result in balancing weights that are easy to manufacture and that can be easily and automatically at least partially assembled.
  • This training can continue an adjoining area of a tub, not shown, with which the balance weight 1 can be connected, according to the application (internal file number PHD 87 257) of the applicant with the same filing date, is reinforced.
  • the mounting iron 5 has at least one U-shaped projection 7. Between the two legs of the extension 7, an essentially elongated through-opening 9 is formed for carrying out fastening screws, not shown.
  • the area adjoining the passage opening 9 is free of concrete, so that due to the fastening there can be no impact of compressive forces on the concrete and the resulting cracking in the base body 3.
  • the approach 7 is surrounded by concrete all around. It protrudes cantilever-shaped into a substantially frustoconical cavity 11 formed inside the base body. So that the shoulder 7 can be brought directly into contact with a retaining element on the tub, and not over an end face of the base body 3, it is at least in the direction of the retaining element led up to the face. For this purpose, it is connected to the mounting iron 5 embedded in the base body 3 by an area 13 bent towards the end face.
  • the second embodiment shown in Fig. 3 egg-nes altogether designated 1 ' only partially shown balance weight has a base body 3', which, like that of the first embodiment, can be made of concrete, and in the reinforcing part a iron 5 'in some areas is embedded.
  • a tab 15 that can be made of metal is connected to the mounting iron 5 ', for example by welding.
  • the also partially embedded in the base body 3 'tab 15 extends radia outward from the base body 3' in a concrete-free, substantially slot-like area 17, which is open in the radially outward direction.
  • the tab 15 is formed for a good connection to the base body 3 'in the form of a segment of a circle and the end projecting into the base body 3' has an angled area 16.
  • the angled area 16 can also be shown in a manner not shown be angled.
  • breakthroughs can also be provided for a good connection to the base body 3 'can be provided for receiving concrete in the part of the tab 15 not shown.
  • the tab 15 also has a through opening 19 into which an elastic bushing 23 made of plastic, rubber or the like can be used to produce an elastic fastening between the tab 15 and an essentially pot-shaped holding element 21 connected to the tub, not shown is.
  • an elastic bushing 23 made of plastic, rubber or the like can be used to produce an elastic fastening between the tab 15 and an essentially pot-shaped holding element 21 connected to the tub, not shown is.
  • the third exemplary embodiment shown in FIGS. 4 and 5 differs from the second exemplary embodiment only in the manner in which the fastening is designed to be flexible in the axial direction. Parts that correspond to those of the second embodiment are provided with the same reference numerals.
  • a resilient tab 29 having a through hole 9 ' is formed on the tab 15', which is designed in the manner of a tab 15 in the form of a segment of a circle.
  • the rag 29 is formed by a tongue-shaped section 15 'punched out from the tab portion.
