Door assembly for use in a home appliance
An appliance and door assembly having a body; a member extending from the body; at least one door mounted to the member; an articulated handle mounted to the door; and a first linkage member connecting the handle to the member. The articulated handle and door includes a door, a handle mounted to the door via a hinge, and a linkage member mounted to the handle via a hinge.
1. An appliance and door assembly, comprising:
a body;
a member extending from the body;
at least one door mounted to said member;
a handle mounted to said door; and
a first linkage member connecting said handle to said member; wherein said member comprises a hinged joint between said member and said first linkage member;
a second linkage member connecting said first linkage member to said handle; and
wherein said door comprises an elongated slot wherein said first and second linkage members slide along said slot.
2. The appliance and door assembly of claim 1 , wherein said member comprises an arm which extends at substantially 90 degrees from said body.
3. The appliance and door assembly of claim 1 , wherein said handle further comprises a hinged joint between said handle and said door.
4. The appliance and door assembly of claim 1 , wherein said handle further comprises a hinged joint between said handle and said second linkage member.
5. The appliance and door assembly of claim 1 , wherein said member comprises a hinged joint between said member and said door.
6. The appliance and door assembly of claim 1 , wherein said handle is mounted to said door so that said handle rotates relative to said door.
7. The appliance and door assembly of claim 6 , wherein when said door is opened and closed, said handle rotates relative to said door.
8. The appliance and door assembly of claim 1 , wherein when said door is turned in a clockwise direction relative to said member, said handle turns in a counterclockwise direction relative to said door.
9. The appliance and door assembly of claim 8 , wherein angular velocity of said handle relative to said door and angular velocity of said door relative to said member vary at different rates at least for a part of the maximum door rotation angle.
10. The appliance and door assembly of claim 8 , wherein a dwell period exists for rotation of said handle or rotation of said door relative to each other.
11. The appliance and door assembly of claim 10 , wherein a beginning of said dwell period coincides either with fully open or fully closed position of said door.
12. The appliance and door assembly of claim 1 , further comprising a second member extending from said body and a second door mounted to said second member.
13. The appliance and door assembly of claim 12 , wherein said second door comprises a second handle and a third linkage member which connects said second handle to said second member.
14. The appliance and door assembly of claim 12 , wherein said second member comprises an arm which extends at substantially 90 degrees from said body.
15. The appliance and door assembly of claim 14 , further comprising a fourth linkage member connecting said third linkage member to said second handle.
16. The appliance and door assembly of claim 12 , wherein said second handle is mounted to said second door so that said second handle rotates relative to said second door.
17. A method of articulating a handle for an appliance door, comprising:
mounting a door to a member of an appliance body via a first hinged joint;
mounting a handle to said door via a second hinged joint;
mounting a first linkage member to said member of said appliance body via a third hinged joint;
mounting a second linkage member to said handle via a fourth hinged joint and to said first linkage member via a fifth hinged joint;
rotating said handle about said second hinged joint;
rotating said door in an opposite direction to said handle about said first hinged joint; and, wherein said first linkage member and said second linkage member slide within an elongated slot within said door.
18. The method of claim 17 , wherein said handle is rotated at the same time as when said door is rotated.
19. The method of claim 17 , wherein said handle and said door are rotated in opposite directions to each other.
20. The method of claim 17 , wherein angular velocity of said handle relative to said door and angular velocity of said door relative to said appliance body are varied at different rates at least for a part of the maximum door rotation angle.
21. The method of claim 17 , wherein a dwell period is introduced for rotation of said handle or rotation of said door relative to each other.
22. The method of claim 21 , wherein a beginning of said dwell period is coincided either with fully open or fully closed position of said door.
