Abstract

A hinge used to mount a door to an overhead storage cabinet is disclosed. The hinge provides a combination linear and articulated motion to provide the clearance between the door of the cabinet and the upper, outer corner of the cabinet. Further, the hinge provides a user assist on the opening of the cabinet door and a self-dampening motion on the closing of the cabinet door without the use of pneumatic cylinders.

Claims

1. A hinge for a cabinet having a vertical door comprising:

a stationary member for attachment to said cabinet;

a moving member for attachment to said door;

a first pivoting member pivotally attached to said stationary member at a single point and pivotally attached to said moving member at a single point;

a second pivoting member pivotally attached to said stationary member at a single point and pivotally attached to said moving member at a single point; and

a spring pivotally attached to said stationary member and to said second pivoting member.

2. The hinge of claim 1 wherein said moving member exhibits a non-centered pivoting motion.

3. The hinge of claim 1 wherein said spring is a spring assembly comprising:

two or more springs arranged in a parallel relationship;

a first attachment member connected to one side of said two or more springs; and

a second attachment member connected to the opposite end of said two or more springs.

4. The hinge of claim 3 further comprising:

a first post defined on said stationary member; and

a second post defined on said second pivoting member;

wherein said first and said second attachment members define holes therein for pivotal connection to said first and said second posts.

5. The hinge of claim 4 wherein said spring assembly contains four springs.

6. The hinge of claim 5 wherein each of said springs has a spring constant of approximately twelve pounds per inch.

7. The hinge of claim 1 further comprising a stop limit defined on said stationary member, said stop limit engaging said second pivoting member when said hinge is in a fully opened position.

8. The hinge of claim 1 wherein said stationary member, said first and second pivoting members and said moving member are constructed from 12 gauge steel.

9. The hinge of claim 1 wherein said spring operates to assist in the opening of said door and further operates to hold said door in an open position.

10. The hinge of claim 1 wherein said spring operates to dampen the motion of said hinge.

11. A hinge for a cabinet having a vertical door comprising:

a stationary member for attachment to said cabinet;

a moving member for attachment to said door;

a first pivoting member pivotally attached to said stationary member and pivotally attached to said moving member at a first pivot point, said first pivot point circumscribing a first arc as said door is opened or closed;

a second pivoting member pivotally attached to said stationary member and pivotally attached to said moving member at a second pivot point, said second pivot point circumscribing a second arc as said door is opened or closed; and

a spring pivotally attached to said stationary member and to said second pivoting member,

wherein said first arc and said second arc intersect.

12. The hinge of claim 11 wherein said spring is a spring assembly comprising:

two or more springs arranged in a parallel relationship;

a first attachment member connected to one side of said two or more springs; and

a second attachment member connected to the opposite end of said two or more springs.

13. The hinge of claim 11 further comprising a stop limit defined on said stationary member, said stop limit engaging said second pivoting member when said hinge is in a fully opened position.

14. The hinge of claim 11 wherein said spring operates to assist in the opening of said door and further operates to hold said door in an open position.

15. The hinge of claim 11 wherein said spring operates to dampen the motion of said hinge.
