Abstract

A top panel of an appliance defines an appliance profile. A hinge assembly coupled to the appliance and an appliance lid allows the lid to pivot relative to the appliance between a lowered position in which the appliance lid rests horizontally above the appliance and a raised position in which the appliance lid defines a non-horizontal plane away from the appliance allowing access to at least a portion of the appliance. The hinge assembly includes one or more snap fit portions to engage the appliance profile of the appliance, such that the appliance operates as a cam and the one or more snap fit portions operates as a follower when in contact with the cam, thereby slowing the descent of the lid from the raised position to the lowered position by travel of the follower along the cam.

First claim

What is claimed is:

1. A soft-close lid assembly for an appliance, comprising:
a top panel of the appliance defining an appliance profile;
an appliance lid; and
a hinge assembly coupled to the appliance and the appliance lid to allow the appliance lid to pivot relative to the appliance between a lowered position in which the appliance lid rests horizontally above the appliance and a raised position in which the appliance lid defines a non-horizontal plane away from the appliance allowing access to at least a portion of the appliance,
wherein the hinge assembly includes one or more snap fit portions configured to engage the appliance profile of the appliance, such that the appliance is configured to operate as a cam and the one or more snap fit portions are configured to operate as a follower when in contact with the cam, and the weight of the appliance lid biases the one or more snap fit portions of the hinge against the appliance profile, thereby slowing descent of the lid from the raised position to the lowered position by travel of the follower along the cam.

2. The appliance of claim 1 , wherein the hinge assembly includes a left hinge and a right hinge supporting respective sides of the appliance lid.

3. The appliance of claim 2 , wherein the one or more snap fit portions include at least one snap fit portion on each of the left and right hinges.

4. The appliance of claim 2 , wherein the left and right hinges are mirror images of one another.

5. The appliance of claim 2 , wherein the left and right hinges are formed of an injected molded polymer.

6. The appliance of claim 1 , wherein the top panel includes one or more heating elements, and the appliance lid is sized to cover the one or more heating elements in the lowered position.

7. The appliance of claim 6 , wherein the appliance lid includes a glass top.

8. The appliance of claim 1 , wherein the weight of the appliance lid biases the one or more snap fit portions of the hinge assembly against the appliance profile.

9. The appliance of claim 1 , wherein the hinge assembly is coupled to the rear of the appliance to allow the lid to pivot relative to the rear of the appliance.

10. A soft-close apparatus for an appliance, comprising:
a hinge for coupling to an appliance and an appliance lid to allow the appliance lid to pivot relative to the appliance,
wherein the hinge includes one or more snap fit portions configured to engage an appliance profile of the appliance, such that the appliance is configured to operate as a cam and the one or more snap fit portions are configured to operate as a follower when in contact with the cam, thereby slowing the descent of the lid by travel of the follower along the cam,
wherein the weight of the appliance lid biases the one or more snap fit portions of the hinge against the appliance profile.

11. The soft-close apparatus of claim 10 , wherein the hinge allows the appliance lid to pivot relative to the appliance between a lowered position in which the appliance lid rests horizontally above the appliance and a raised position in which the appliance lid defines a non-horizontal plane away from the appliance allowing access to at least a portion of the appliance.

12. The soft-close apparatus of claim 10 , wherein each of the snap fit portions defines a protrusion extending towards a side of a top panel of the appliance, the top panel defining the appliance profile against which the snap fit portions run in a controlled motion to brake rotational motion of the appliance lid against the profile of the top panel.

13. The soft-close apparatus of claim 12 , wherein the one or more snap fit portions include a plurality of snap fit portions.

14. The soft-close apparatus of claim 11 , further comprising the appliance lid, wherein the appliance lid is sized to cover one or more heating elements when in the lowered position.

15. The soft-close apparatus of claim 14 , wherein the appliance lid includes a glass top.

16. A soft-close apparatus for an appliance, comprising:
an appliance lid; and
a hinge for coupling to an appliance and an appliance lid to allow the appliance lid to pivot relative to the appliance, wherein the appliance lid is sized to cover one or more heating elements when in the lowered position,
wherein the hinge allows the appliance lid to pivot relative to the appliance between a lowered position in which the appliance lid rests horizontally above the appliance and a raised position in which the appliance lid defines a non-horizontal plane away from the appliance allowing access to at least a portion of the appliance,
wherein the hinge includes one or more snap fit portions configured to engage an appliance profile of the appliance, such that the appliance is configured to operate as a cam and the one or more snap fit portions are configured to operate as a follower when in contact with the cam, thereby slowing the descent of the lid by travel of the follower along the cam, and
wherein the weight of the appliance lid biases the one or more snap fit portions of the hinge against the appliance profile.

17. The soft-close apparatus of claim 10 , wherein the hinge is formed of an injected molded polymer.

18. The soft-close apparatus of claim 10 , wherein the hinge is coupled to the rear of the appliance to allow the lid to pivot relative to the rear of the appliance.

19. The soft-close apparatus of claim 10 , wherein the hinge defines an aperture configured to receive a pin about which the hinge provides the appliance lid to pivot relative to the appliance.

20. The soft-close apparatus of claim 10 , wherein the hinge further comprises a lid support having a longitudinal groove for mounting of the appliance lid.
