Abstract
Abstract A top loading clothes washer adapted for installation under a fixed or stationary upper structure such as a stacked dryer or countertop wherein the washer is pivotable to a forward tilt-out position providing access to its top. The bottom front of the washer is truncated and the pivot axis which is defined by a stable base is behind the truncation and in front of the center of gravity of the washer. A latch is provided to lock the washer in its upright washing position. The latch is releasable by an operator actuated control provided the water level in the tub is below a predetermined level. Accordingly, forward tilting of a full tub is prevented. Also, the operator actuable control energizes a mechanism which assists in the forward tilting of the washer thereby reducing the pull force required of the operator. More specifically, a biased hinge creates a backward torsion on the washer to provide increased stability during a spin cycle and the mechanism functions to counteract the torsion. Further, a washer spin cycle is delayed until at least a portion of the water has been pumped from the tub.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
89 words
A top loading clothes washer rotatable about a horizontal axis to a forward tilt-out position from under a stationary structure, comprising: a stable base comprising means for pivotally supporting said washer about said horizontal axis wherein said washer is rotatable between an upright position used for washing and said tilt-out position used for loading and unloading clothes; and means responsive to water in said washer being above a predetermined level for locking said washer in said upright position thereby preventing forward rotation of said washer toward said tilt-out position.
Claim 2
Dependent Claim
89 words
A top loading clothes washer rotatable about a horizontal axis to a forward tilt-out position from under a stationary structure, comprising: a stable base comprising means for pivotally supporting said washer about said horizontal axis wherein said washer is rotatable between an upright position used for washing and said tilt-out position used for loading and unloading clothes; and means responsive to water in said washer being above a predetermined level for locking said washer in said upright position thereby preventing forward rotation of said washer toward said tilt-out position.
Claim 3
Dependent Claim
17 words
The washer recited in claim 1 wherein said locking means comprises a latch mounted to said base.
Claim 4
Dependent Claim
33 words
The washer recited in claim 2 wherein said locking means further comprises a solenoid mounted to said washer and having a plunger aligned for engagement with said latch in said upright washing position.
Claim 5
Dependent Claim
48 words
The washer recited in claim 3 wherein said locking means further comprises an operator actuable switch for energizing said solenoid for disengaging said plunger from said latch in said upright washing position, said locking means further comprising a pressure sensitive switch in series with said operator actuable switch.
Claim 6
Dependent Claim
171 words
In combination: a clothes washer having a housing comprising a bottom platform, a cabinet front, cabinet sides, and a cabinet top having an opening for loading and unloading clothes; a stable rectangular base having front, side, and back members; said base comprising means for pivotally supporting said housing about a horizontal axis lateral to said washer between said cabinet front and the center of gravity of said washer; said washer having at least one back foot for supporting the rear of said washer on said back member of said base when said washer is an upright washing position, said foot horizontally securing said washer to said base; said washer being rotatable about said axis from said upright position to a forward tilt-out position used for loading and unloading clothes through said opening; means for locking said washer in said upright position; an operator actuable switch for unlocking said locking means; and means responsive to water in said washer being above a predetermined level for preventing said locking means from being unlocked.
Claim 7
Dependent Claim
171 words
In combination: a clothes washer having a housing comprising a bottom platform, a cabinet front, cabinet sides, and a cabinet top having an opening for loading and unloading clothes; a stable rectangular base having front, side, and back members; said base comprising means for pivotally supporting said housing about a horizontal axis lateral to said washer between said cabinet front and the center of gravity of said washer; said washer having at least one back foot for supporting the rear of said washer on said back member of said base when said washer is an upright washing position, said foot horizontally securing said washer to said base; said washer being rotatable about said axis from said upright position to a forward tilt-out position used for loading and unloading clothes through said opening; means for locking said washer in said upright position; an operator actuable switch for unlocking said locking means; and means responsive to water in said washer being above a predetermined level for preventing said locking means from being unlocked.
Claim 8
Dependent Claim
21 words
The combination recited in claim 5 wherein said locking means comprises a latch mounted to said back member of said base.
Claim 9
Dependent Claim
38 words
The combination recited in claim 6 wherein said locking means further comprises a solenoid connected to said bottom platform of said washer housing, said solenoid having a plunger aligned for engaging said latch in said upright washing position.
Claim 10
Dependent Claim
97 words
In combination: a top loading washer pivotally supported about a horizontal axis for rotating between an upright washing position and a forward tilt-out position used for loading and unloading clothes from the top thereof; means for providing a torque force on said washer urging rotation of said washer about said axis toward said upright washing position for providing stability during washing dynamics of said washer; and an operator actuable control for at least partially counteracting said torque force of said providing means to assist in opening said washer from said upright washing position to said tilt-out position.
Claim 11
Dependent Claim
97 words
In combination: a top loading washer pivotally supported about a horizontal axis for rotating between an upright washing position and a forward tilt-out position used for loading and unloading clothes from the top thereof; means for providing a torque force on said washer urging rotation of said washer about said axis toward said upright washing position for providing stability during washing dynamics of said washer; and an operator actuable control for at least partially counteracting said torque force of said providing means to assist in opening said washer from said upright washing position to said tilt-out position.
Claim 12
Dependent Claim
20 words
