Definitions

  • the present invention relates to a device for anchoring the basket damper in washing machines or the like .
  • the linen basket of conventional washing machines is suspended, at a top portion thereof, to the bearing framework of the washing machine by a pair of springs and, at a bottom portion thereof, it is anchored or latched to the washing machine bearing framework by a pair of dampers.
  • each damper to the basket is conventionally performed by a bolt, which is engaged in a throughgoing hole defined in a pair of ears of a bracket, which is fixed to the basket.
  • a perforated end portion of the damper is engaged between the ears of the mentioned ear pair, by arranging the end hole of the damper aligned with the holes of the ear pair and, through the mentioned holes, being engaged and clamped the coupling bolt.
  • a rigid spacing bushing and, between the latter and the end hole of the damper, a resilient spacer bushing is provided.
  • This anchoring system is very reliable and efficient, but it is unnecessarily sized with respect to the occurring loads. Moreover, the above disclosed system is very expensive and the making method therefor requires a lot of operating steps.
  • a further alternating solution for anchoring the mentioned dampers to the washing machine baskets is that of using a resilient pin, made of a plastic material, and provided for replacing the connecting bolt.
  • This system provides the advantages of a small cost and a quicker assembling method.
  • the plastic material resilient pin provides a small outwardly directed radial load on the inner surface of the hole receiving said resilient pin, as well as a practically zero cross load, since the tooth element usually included in the mentioned pin, at an axial end portion thereof, is exclusively used for anti-disengaging purposes.
  • the above mentioned tooth element because of its construction, can not provide sufficient axial forces to cross press the anchoring system so as to overcome possible clearances due to inevitable making tolerances and for increasing the stiffness required for limiting possible unbalancings of the swinging assembly comprising the linen basket as well as the related coupling elements for coupling said basket to the washing machine framework.
  • the aim of the present invention is to overcome the above mentioned problems, by providing a device for anchoring or latching the washing machine basket dampers, specifically designed for assuring a very high radial load as well as a high modulable cross load.
  • a main object of the present invention is to provide such a device which is very reliable in operation and has a long duration.
  • Another object of the present invention is to provide such a device which can be quickly assembled.
  • Yet another object of the present invention is to provide such a device which can be made at a very competitive cost.
  • an anchoring device for anchoring the basket damper in washing machines and the like, characterized in that said anchoring device comprises a resilient pin, having a circular cross- section cylindric hollow body, provided, on an outer side surface thereof, with two shoulders which are axially spaced from one another.
  • Said body is provided with at least an axial slit for allowing said body to be radially compressed.
  • At least one of the mentioned two shoulders is coupled to the nearer axial end portion of said body, by a conical surface portion defining an end portion for engaging therein said body.
  • Figure 1 is a schematic view illustrating a linen washing machine
  • Figure 2 is a perspective view illustrating the resilient pin, according to a first embodiment thereof
  • Figure 3 illustrates the resilient pin of Figure 2 , by a side elevation view
  • Figure 4 is a further side elevation view illustrating a second embodiment of the resilient pin
  • Figure 5 is a further side elevation view illustrating a third embodiment of the mentioned resilient pin
  • Figures 6 and 7 are respective partially cross-sectional side elevation view illustrating the assembling method for assembling the resilient pin shown in Figures 2 and 3;
  • Figure 8 illustrates an enlarged detail of
  • Figure 9 is a further partially cross- sectional side elevation view illustrating a fourth embodiment of the resilient pin according to the present invention.
  • Figure 10 is a further partial cross- sectional side elevation view illustrating a fifth embodiment of the resilient pin according to the present invention
  • Figure 11 is yet a further partial cross- sectional side elevation view illustrating the use of the mentioned resilient pin, related to the embodiment being shown in Figure 9
  • Figure 12 illustrates on an enlarged scale an enlarged detail of Figure 11;
  • Figures 13 to 16 are further partial cross- sectional side elevation views illustrating modified embodiments of the resilient pin according to the present invention.
  • Figure 17 is a cross-sectioned side view illustrating another modified embodiment of the subject resilient pin
  • Figure 18 illustrates an extended flat view of a dished sheet metal element provided for use in making the resilient pin shown in Figure 17;
  • Figure 19 is a cross-sectioned side view of a further pin
  • Figure 20 is a side cross-sectioned view of the pin shown in Figure 19;
  • Figure 21 is a side view of a lateral portion of a damper provided for cooperating with and for anchoring to a support of a washing machine by the mentioned resilient pin, the contour thereof having an approximate sinusoidal configuration at the section C-C shown in Figure 20.
  • the anchoring device comprises a resilient pin which, in its several embodiments, has been generally indicated by the reference numbers la, lb, lc, Id and le, and which is provided with a cylindrical hollow body, of circular cross-section, which, on its outer side surface is provided with two shoulders 2 and 3 which are axially spaced from one another.
  • the resilient pin body is moreover provided with an axial slit 4, for allowing the pin body to be resiliently radially compressed. At least one of the two shoulders 2, 3 is coupled to the nearer axial end portion of the pin body by a conical surface portion, which defines an end portion for engaging therein said resilient pin.
  • the body of the resilient pin is preferably made of a metal curved and contoured blade element, having high elastic deformability properties.
  • the resilient pin la is provided, in its first embodiment, with an axial slit or cut 4, substantially extending through the overall axial length of said pin la.
  • the two shoulders 2 and 3 are defined by ridges projecting from the outer side surface of the resilient pin body. Between the two shoulders 2 and 3, the pin body has a substantially cylindrical configuration.
  • the two shoulders 2 and 3 are coupled to the related axial end portions of the body of the resilient pin by two frustum of cone shaped portions 5 and 6, allowing the resilient pin la to be easily assembled, during the assembling operation, as it will become more apparent hereinafter.
  • the shoulders 2 and 3 are provided by sheared or cut tooth elements 7 and 8 of the body of the pin lb, said tooth element being outwardly bent.
  • the two shoulders 2 and 3 are coupled to their related axial end portions of the pin body, by two conical surface portions 9 and 10.
  • the two shoulders 2 and 3 are also defined by ridges, which project from the outer side surface of the body of the pin lc, as in the first embodiment, but with the difference that only the shoulder 2 is coupled to the nearer axial end portion of the body 2, by a conical surface portion 11.
  • the body of the pin is also provided with a longitudinal slit 12, 13 extending substantially through the overall axial length of the pin body.
  • a longitudinal slit 12, 13 extending substantially through the overall axial length of the pin body.
  • the pin is provided to be engaged through a pair of holes 15, 16, formed in a pair of parallel ears 17 and 18, rigid with the washing machine basket 19, as well as through a hole 20 formed through an end portion of the damper 21, which is brought into alignment with the holes 15 and 16.
  • a resilient spacing bushing 22 is pre-engaged through said hole 20.
  • the distance existing between the two shoulders 2 and 3 of the pin, in a rest condition thereof, is preferably less than the distance existing between the two outer parallel faces of the ears 15 and 16 thereby providing, as clearly shown in Figure 8, an axial load of the pin against the ears 15 and 16 so as to overcome possible clearances deriving from the working tolerances of the pieces being assembled by the mentioned pin.
  • the pin Id is also provided with two shoulders 2 and 3, the shoulder 2 being defined by tooth elements 30 and being coupled to the nearer axial end portion of the pin body, through a conical surface 31.
  • the other shoulder 3 is defined by a reversed wave edge, in the form of the cup spring, of the other axial end portion of the pin body.
  • the distance, at a rest condition, of the shoulders 2 and 3 is less than the distance of the outer surfaces of the two ears 17 and 18.
  • a greater resiliency of at least one of the two shoulders of the pin will be obtained, so as to allow to recover comparatively large clearances, as is clearly shown in Figures 11 and 12.
  • one of the two shoulders is defined by sheared or cut-out tooth element 33, which have their free end portions bent in the direction of the axis of the body of the pin le, in order to provide the shoulder 2 with a great resiliency, to provide an operation of the pin like that of the pin shown in Figure 9.
  • the other shoulder 3 is merely defined by a upturned edge 34 of an axial end of the pin body.
  • the mentioned resiliently compressible element in particular, can comprise, as shown in Figures 13 and 15, a cup-like spring 35 and 36.
  • the above mentioned resiliently compressible element can be also constituted by a ring-like pad, of a resiliently compressible nature, as indicated at 37, or, as shown in Figure 16, it can comprise either one or more coils of a coil spring 38.
  • the pin shown in Figure 17 comprises a portion operating as a latching ring, in replacement of the above disclosed solution comprising several sheared or semi-sheared tooth elements, or dished tooth elements.
  • Said anti-rotating ring 41 after engaging with the corresponding female contour 46 formed on the pin receiving bridging element, will provide a suitable anti-rotating torque.
  • an anchoring device for anchoring the basket damper in washing machines and the like which provides a high radial load, as well as high modulable axial load allowing to recover possible clearances due to the working tolerances of the elements to be coupled by the pin, thereby increasing the required stiffness, and reducing possible unbalancings of the swinging assembly of the washing machine.
