Abstract

An appliance hinge assembly includes: a support member configured to be secured to an appliance; a claw pivotally coupled to the support member; and a lock member pivotally coupled to the claw, wherein the claw and the lock member can be coupled together to create a bounded space therebetween.

Claims

1. An appliance hinge assembly comprising:

a support member configured to be secured to an appliance;

a claw pivotally coupled to the support member; and

a lock member pivotally coupled to the claw,

wherein the claw and the lock member can be coupled together to create a bounded space therebetween.

2. The appliance hinge assembly of claim 1, wherein the claw includes a hook-shaped end that cooperates with the lock member to create the bounded space therebetween.

3. The appliance hinge assembly of claim 1, wherein the lock member includes a hook-shaped end that cooperates with the claw to create the bounded space therebetween.

4. The appliance hinge assembly of claim 3, wherein the claw includes a hook-shaped end that cooperates with the hook-shaped end of the lock member to created the bounded space therebetween.

5. The appliance hinge assembly of claim 1, further comprising a receptacle having a pin and wherein when the support member is coupled to the receptacle, the pin can be secured within the bounded space.

6. The appliance hinge assembly of claim 5, wherein when the pin of the receptacle is secured within the bounded space, the hinge assembly is locked in a first operative position.

7. The appliance hinge assembly of claim 1, wherein one of the lock member and the claw includes at least one protrusion extending from a surface thereof and the other of the lock member and the claw includes at least one of a hole or a recess configured to receive the at least one protrusion therein.

8. The appliance hinge assembly of claim 1, further comprising a link member, the link member having a first end portion secured to a biasing member, a second end portion secured to the claw, and a middle portion coupled to a shaft.

9. The appliance hinge assembly of claim 8, wherein the support member defines a path of travel for the shaft.

10. The appliance hinge assembly of claim 9, wherein the path of travel includes a stop portion, the stop portion configured to stop an appliance door at a position intermediate a fully open and a fully closed position.

11. The appliance hinge assembly of claim 1, wherein the lock member includes a first end configured to lock with the claw and a second end configured to lock with the support member, wherein when the first end is locked with the claw, the hinge assembly is locked in a first position, and wherein when the second end is locked with the support member, the hinge assembly is locked in a second position.

12. An appliance hinge assembly comprising:

a support member;

a claw pivotally coupled to the support member;

a lock member pivotally coupled to the claw;

a receptacle; and

a pin secured to the receptacle,

wherein the claw and the lock member are configured to trap the pin within a bounded space created by the claw and the lock member to retain the appliance hinge assembly in a first predetermined position.

13. The appliance hinge assembly of claim 12, wherein each of the claw and the lock member includes a hook-shaped end configured for snap engagement with each other.

14. The appliance hinge assembly of claim 12, wherein the lock member includes an end portion having at least one hole through a surface thereof and wherein the claw includes an end portion having at least one protrusion extending from a surface thereof such that the at least one protrusion is configured to extend into the at least one hole when aligned.

15. The appliance hinge assembly of claim 12, wherein the lock member is further configured to engage a corresponding portion of the support member to retain the appliance hinge assembly in a second predetermined position.

16. The appliance hinge assembly of claim 15, wherein the lock member includes a tab configured for engagement with a notch provided in the support member.

17. The appliance hinge assembly of claim 12, wherein the receptacle includes an aperture, the aperture being tapered at one end to mitigate side-to-side motion of the receptacle with respect to the support member.

18. An appliance hinge assembly comprising:

a support member;

a claw pivotally coupled to the support member; and

locking means for locking the appliance hinge assembly in first and second predetermined positions, the locking means being coupled to the claw.

19. The appliance hinge assembly of claim 18, further comprising a receptacle and wherein the locking means is configured to lock the claw to the receptacle to lock the appliance hinge assembly in the first predetermined position.

20. The appliance hinge assembly of claim 19, wherein the locking means is configured to engage the support member to lock the appliance hinge assembly in the second predetermined position.
