Definitions

  • the following invention consists of a subjection system for washing machine counterweights, of the type of those in which the counterweight is formed by a rectangular-section block provided with a concavity in relation to the side whereby it is attached to the tub to adapt to shape thereof, so that said counterweight remains in relation to the upper part of the washing machine tub positioning.
  • the anchoring element can be formed by a general cylindrical-shaped body, provided with a central axial threaded hole in part of its height and the rest of its height is defined by a series of branches, longitudinally separated from one another, which will be fitted in the corresponding hole of the concrete block, the anchoring occurring when a screw, which will open the independent branches, is threaded.
  • the securing system disclosed is applied to the anchoring of the upper counterweight of washing machine tubs, so that said counterweight is set in the upper part of the tub in its positioning in the washing machine.
  • the counterweight defined by a block of pressed concrete, is thus fixed to the body of the tub, which has an upper counterweight and a front counterweight.
  • fixing elements are defined during the manufacturing process which are formed by pairs of curved facing projections which form a guide, whilst a pair of through holes in relation to the side whereby it is attached to the tub are defined in the pressed concrete block which acts as a counterweight.
  • the screws are thus placed on the guides defined in the tub body with the head fitted in the slot formed by the pair of curved facing projections, so that it is fixed using a flat washer, a spring washer and the corresponding nut.
  • GB 2 121 833 a subjection system for washing machines counterweights, wherein the counterweight is of the kind of those that are made up of a pressed concrete block that is placed in the upper part of the washing machine tub. While the known tub is from metal sheet, additional parts also from metal sheet, welded to the tub, are necessary for the fixing of the concrete block of counterweight. this kind of fixing is not usable with plastic tanks.
  • a securing system for upper counterweights of washing machine tubs is disclosed, which is of the type of those formed by a block of pressed concrete positioned in the upper part of the tub in its arrangement in the washing machine, being formed by the means of anchoring the counterweight to the tub and the means to solidly fix both bodies.
  • the claimed system is defined by claim 1.
  • the means of anchoring the counterweight to the plastic tub are defined by a pair of projections joined to the tub, of dovetailed-section, or equivalent shape, longitudinally divided in two halves, which correspond to their respective recesses in the counterweight of equal dovetailed-section, or equivalent shape.
  • the dovetailed-section projections divided in two longitudinal halves, have a central longitudinal recess through which a rod passes which causes the divergence of both halves, pressing against the counterweight and solidly fixing it, preventing any displacement of the counterweight.
  • the system of anchoring the counterweight to the tub can be defined by a pair of general tubular-shaped projections joined to the tub, in a pair of parallel axial flanges, said body being formed by a perimetrically closed section with a central axial threaded hole and with axial grooves which define independent branches on its outer section, which are fitted in respective similar sectioned holes of the counterweight, and which are closed by one of their bases.
  • Said closed base of the counterweight holes wherein the bodies joined to the tub are fitted has a threaded through hole coinciding with the threaded hole of the body joined to the tub, fixing it by means of a threaded screw which, on acting on the independent branches, separates them from one another, coming up against the body of the counterweight and forming a perfect fit, preventing the displacement of the counterweight in any direction.
  • the securing system for upper counterweights of washing machine tubs is formed by the counterweight 1 and anchoring element thereof joined to the tub, so that said counterweight 1 has the central part 2 of the side whereby it is attached to the tub 3 of curved-concave shape, similar to the shape of the tub, as well as a pair of dovetailed-section projections 4.
  • the anchoring element joined to the tub 3 is thus defined by a pair of dovetailed-section projections 5, centrally and longitudinally divided in two halves with a recess 6 between their opposite sides which define a circular slot, which on inserting a rod therein, causes them to separate, diverging against the counterweight and solidly fixing them.
  • the pair of projections joined to the tub 3 are defined by a general cylindrical tubular-shaped body 7, provided with a pair of parallel axial flanges 8, through which it is joined to the tub 3 and which are combined with respective similar sectioned recesses 9 of the counterweight 1.
  • one of the bases 10 of the recesses 9 is closed and has a hole 11, whilst the body 7 has a perimetrically closed section with a central axial threaded hole 12, and an outer section that has axial grooves 13 that define independent branches 14.
  • the closed base 10 of its recesses 9 is placed in relation to the perimetrically closed base of the body 7, and with its central axial hole 12 in relation to the hole 11 of said perimetrically closed base of the body 7.

Claims (7)

  1. Système d'assujettissement dans une machine à laver pour fixer un contrepoids de machine à laver à une cuve de machine à laver, le contrepoids (1) étant du type de ceux qui sont constitués d'un bloc de béton comprimé, qui est placé dans la partie supérieure de la cuve de machine à laver (3), caractérisé en ce que
    le contrepoids (1) est muni d'une paire ou de quelques évidements (4, 9);
    la cuve de machine à laver (3) est munie d'une paire de saillies (5, 7) assemblées à celle-ci, lesdites saillies étant l'élément d'ancrage du contrepoids (1) à la cuve (3);
    lesdites saillies (5, 7) de la cuve (3) présentent une plus grande largeur dans la partie externe et sont de section similaire à celle desdits évidements (4, 9);
    lesdites saillies (5, 7) de la cuve (3) sont insérées dans les évidements correspondants (4, 9) de sorte que la libération verticale du contrepoids (1) est évitée;
    les saillies (5, 7) possèdent une cavité centrale longitudinale (évidement 6, 12) dans laquelle une tige ou une vis est insérée pour faire diverger les saillies (5, 7) contre le contrepoids (1) et réaliser une fixation par assemblage qui empêche tout déplacement du contrepoids.
  2. Système d'assujettissement selon la revendication 1, caractérisé en ce que les moyens d'ancrage du contrepoids (1) à la cuve (3) sont définis par une paire de saillies à section en queue d'aronde (5), assemblées au corps de cuve, divisées longitudinalement en deux moitiés qui correspondent à des évidements respectifs (4) de section égale du contrepoids (1).
  3. Système d'assujettissement selon les revendications 1 et 2, caractérisé en ce que la fixation solide du contrepoids (1) à la cuve (3) est formée par une tige ou une vis traversant l'évidement (6), qui est au centre entre les deux moitiés des saillies à section en queue d'aronde (5), et qui les fait diverger et appuyer sur le corps de contrepoids.
