The flexible mounting element is a single resilient component that provides dampening and restoring force. The method of using the flexible mounting assembly includes providing a flexible mounting element within the socket of a support frame of the laundry assembly and dampening vibrations from the laundry assembly by resisting pivoting of the suspension rod engaging the flexible mounting element.
Description
TITLE: FLEXIBLE MOUNTING ASSEMBLY FUR A LAUNDRY APPLIANCE
AND ME'1 HOD OF USE
BACKGROUND OF THE INVENTION
Laundry appliances have been developed that support an internal laundry assembly with a hanging suspension system or a hung strut assembly. Previously, these systems have been designed using a rigid part to rotate relative to a rigid support member.
Commonly, this design has taken a rigid ball and socket configuration which requires relative sliding between the ball and socket components to permit the hung suspension rod to pivot.
The prior art encounters a number of disadvantages including wear at the interface between the two rigid components that may effect performance and may create additional vibration transferred to the frame in the laundry assembly. In addition, this prior art often does not have an interface between the two rigid components that prevents the separation of the ball component from the socket component especially during large displacement situations. Additionally, the prior a_~t devices often include temporary solutions including grease between the interface of the two rigid components, the application of Teflon~, additional plastic parts, or some other combination thereof. Still other solutions require mufti-piece rigid members.
The prior art recognized the use of flexible components to dampen vibrations resulting from the hung suspension rod laundry assembly configuration. These utilize multiple rubber members clamped together to form a flexible joint. This solution lacks the simplicity of a single part mounting element with integral attachment features to secure the part to the frame of the washer.
Therefore, a primary objective of the present invention is to overcome the problem of the prior art.
A further objective of the present invention is a flexible mounting assembly for use with a laundry appliance which is economical to manufacture, durable, and effective in use.
These and other objectives become apparent from the following description of the invention and claims.
SL~MIvIARY OF THE INVENTION
'hhe foregoing problems of the prior art may be solved by a mounting element designed for use in a laundry appliance having a laundry assembly hung bs- a suspension rod to an upper frame that is a single resilient component that provides dampening and/or restoring force. 'The mounting element has a body having a passageway that accepts a suspension rod, a seating surface adapted for mating.with a socket on a frame of the laundry appliance, and an attachment integrally formed with the body to secure the body to the upper frame.
According to another feature of the present invention the attaclunent may be a snap-fit connection, a twist-lock connection, a helix comiection, adhesive, and/or over-molding the mounting element into the frame. By using a single resilient component there is a cost reduction compared to the rigid sliding interface of the prior art.
Additionally, the foregoing problems of the prior art may be overcome utilizing a flexible mounting assembly that includes a socket on the frame of a laundry assembly with an opening to receive the suspension rod and a flexible mounting element, the flexible mounting element having a body with a passageway therethrough so that the suspension rod can extend through the body and a seating surface for mating with the socket. The flexible mounting element allows the suspension rod to pivot to provide dampening and/or restoring force to the laundry assembly.
According to another feature of the present invention, the flexible mounting element is made of an elastomeric material. The elastomeric material grips the socket and prevents separation of the mounting element from the socket.
According to another feature of the present invention, the flexible mounting element provides a dampening force as a response to the pivoting of the suspension rod.
According to another feature of the present invention, the flexible mounting element provides a non-linear restoring force during large displacement situations of the laundry assembly in response to the pivoting of the suspension rod.
The foregoing problems of the prior art may also be solved by a method of using a flexible mounting assembly with a laundry assembly, utilizing a suspension rod, including the step dampening vibration from the laundry assembly by resisting pivoting of the suspension rod engaging the flexible mounting element.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to Figure l, a top loading, vertical axis washing machine 10 includes a cabinet 12 having a control panel 14 and a door 16 movable between an open and closed position.
As illustrated in Figure 2, the washing machine 10 has a laundry assembly 18 supported by front suspension rod 20 and rear suspension rod 22. The suspension rods 20, 22 cooperate to brace the laundry assembly 18 against forces during all portions of the laundry cycles.
The front rod 20 has a bottom end 24 that is moveably connected within a front shock 26 that is attached to base 28. The front rod has a top end 30 removably attached to a front arm 32 of the laundry assembly. The rear rod 22 is moveably connected at a bottom end 34 to a rear shock 36. 'hhe rear shock 36 is removably attached to a rear arm 37 of the laundry assembly 18. 'the front and rear shocks 26, 36 provide a dampening force to the laundry assembly 18 during large displacements.
The rear rod 22 has a top end 38 attached to an upper frame 40 of the washing machine 10 by a support brace 42. A mounting element 44 is provided between the rod 22 and the support brace 42 to provide dampening. The mounting element 44 also applies a restoring force which centers the laundry assembly 18 in the washing machine I0. The flexible mounting element 44, in combination with the support brace 42 is generally referred to as a flexible mounting assembly 45. In an alternate embodiment (not shown), the flexible mounting element 44 may be attached directly to the upper frame 40.
The mounting element 44 is flexible and may be made of a elastomeric material such as ethylene-propylene-dime monomer rubber (EPDM), styrene-butadiene rubber (SBR), thermoplastic elastomer/rubber (TPE/TPR), or other flexible material.
As shown in Figure 3, the flexible mounting element 44 is placed upon strut rod 22.
The flexible mounting element 44 is obstructed from movement upward beyond the top end 38 of the rod 22 by a washer 46 abutting crimps 48. The washer 46 is designed to fit adjacent an upper horizontal surface 50 of the flexible mounting element 44.
The horizontal surface 50 may be upon a conical platform 52. Alternatively, as seen in Figure 6, the horizontal surface 50 may have alternative locations including the bottom surface of a recess 53 upon the top end of the flexible mounting element 44.
The flexible mounting element 44 has a seating surface 54 as best seen in Figures 5-8 that is substantially spherical shaped and convex. This seating surface 54 may take various other shapes and configurations but is particularly useful in this shape and form when used as a retrofit replacement for rigid ball mounting elements.
As shown in Figure 3, a socket 56 with a central hole 59 is located on the support brace 42. As illustrated, the socket 56 is substantially spherical shaped and concave. The socket further includes a lower cylindrical flange 58 to assist in aligning the flexible mounting element 44 within the socket 56. The flange 58 cooperates with an outer rim 60 of the flexible mounting element 44. At a lower portion of the outer rim 60 an attachment 62 is provided to connect the mounting element 44 to the support brace 42. As illustrated, a lip attachment 62 is shown that permits a "snap-fit" between the flexible mounting element ~l-1 and the support brace 42. The snap-fit occurs when the attachment lip 62 is fitted adjacent the flange ~8 and pushed through central hole ~9, allowing the attachment lip 62 to be released outv.~~ardl5~. The snap-fit feature may have a high insertion/retention force by utilizing the weight of the suspended laundry unit 18 to help seat the flexible mounting element 44 during assembly. Other attaclunents 62 may include a twist-lock, helix, adhesive, tongue and groove, over-molding into the socket, and/or other structure that attaches the flexible mounting element to either the support brace 42 or upper frame 40.
As seen in Figure 4, once seated, the flexible mounting element 44 eliminates a bearing/wear surface that is typical of a rigid ball and socket type mounting element.
Wearing and abrasion at this interface can affect performance of the washing machine or provide an interface through which vibration is transferred to the frame 40.
The described attachment of the flexible mounting element 44 to the support brace 42 creates an interface that is not susceptible to wearing of the socket 56.
As seen in Figure 5, the flange 58 may have a lower horizontal surface 64 that engages the lip 62 to hinder an upward vertical force from disengaging the flexible mounting element 44 from the support brace 42.
As seen in Figures 5-8, the flexible mounting element 44 has an inner hollow shaft 68 extending downward from a main body 70 of the flexible mounting element 44.
The inner hollow shaft 68 and the main body 70 has formed therein a common rod passageway 72. A gap 74 is provided between the outer rim 60 and the inner hollow shaft 68.
As seen in Figure 7, in Iow displacement situations such as one that occurs when a well balanced load is operated at a high spin, no dampening is needed and therefore shaft 68 gripping the rod 22 moves toward the outer rim 60 closing the gap 74 but with little damping force. In these situations the seating surface 54 does not move within the socket 56 thus avoiding wearing at this interface.
As seen in Figure 8, a non-linear restoring force can be provided where there is a larger displacement of the suspended laundry assembly I 8 such as passing through critical speeds. In this situation, the horizontal gap 74 is closed by the rod 22 pivoting the shaft 68 i() of the flexible member 44 until it contacts rim 60 which generates a significantly higher, thus non-linear, restoring f~orcc by the body 70 against the upper portion 38 of rod 22. .
The invention has been shown and described above with the preferred embodiments, alld it is understood that many modifications, substitutions, and additions may be made which are within the intended spirit and scope of the invention.
From the foregoing, it can be seen that the present invention accomplishes at least all of its stated objectives.
