Definitions

  • ABSTRACT OF THE DISCLOSURE A wheeled mechanism for stabilizing a washing machine particularly during the period that the washing machine drum rotates at high speed.
  • a pair of wheels are mounted such that the wheel axes are at an obtuse angle with respect to each other. Further, at least one of the wheels is elliptical in shape.
  • This invention relates to washing machines of the type in which the base surface is provided with wheels.
  • machines of this type acquire an alternating movement about their position of equilibrium in the longitudinal direction, that is to say at right angles to the axis of rotation of the drum. If the amplitude of this movement remains small it sufiicies to make allowance for it upon installation of the machine, but if the amplitude is considerable the machine may tend to displace itself, which may cause damage to the machine or to articles present in the vicinity thereof.
  • the present invention aifords the advantage that no additional mechanical device whatever is necessary for limiting the amplitude of the alternating movement in the longitudinal direction and thus avoiding displacement of the machine.
  • the invention is characterized in that the axes of at least two of the wheels define an obtuse angle between 170 and 179 to one another.
  • the tendency of the machine to displace itself is decreased still further if, according to the invention, the machine has at least one wheel in which the distance from the running surface to the axis of rotation is variable.
  • variable distance from the running surface to the axis of rotation is to be understood herein to mean that the distance between the running surface and the axis, as viewed in the direction of the running surface, is not constant such as is the case, for example, if the wheel is elliptical in shape, or if the axis has an eccentric position in a cylindrical wheel.
  • FIG. 1 is a view on the bottom of a washing machine of known type
  • FIG. 2 is a view on the bottom of a washing machine a co di g o the inve ti a d
  • FIG. 3 shows one example of a wheel according to the invention.
  • FIG. 1 shows the positions of wheels 1, 2 and 3 provided under a base plate 4 of a washing machine of known type.
  • the axes of the wheels 2 and 3 are aligned and indicated by a dot-and-dash line 6 at right angles to said median plane.
  • FIG. 2 shows an arrangement of the wheels 1, 2 and 3 in accordance with the invention.
  • the mounting of the wheel 1 is similar to that in FIG. 1.
  • the axes 7 and 8 of the wheels 2 and 3 are at angles between /2 and 5 to the dot-and-dash line 6 thereby defining an obtuse angle therebetween ranging between and 179.
  • the longitudinal axis passes through the point of intersection of the wheel axes and bisects the angle therebetween.
  • FIG. 3 shows an example of a wheel 9 according to the invention which is mounted on a spindle 10.
  • a running surface 11 is symmetrical with respect to the spindle 10, that is to say elliptical in this particular case.
  • a wheel mounting assembly for resisting displacement along a longitudinal axis of a machine comprising: a plurality of wheels rotatably mounted on the base of said machine, the central axes of at least two of said wheels being substantially parallel to said base and positioned at an obtuse angle to one another, said angle ranging from 170179, said obtuse angle being bisected by the longitudinal axis of said machine.
  • a wheel mounting assembly according to claim 1 wherein the running surface of at least one of said wheels is at a variable distance from the central axis of said at least one wheel.
