Adjustable hinge
View Patent ↗An adjustable hinge fixture that includes a base plate for adjustable fixation to an article of furniture, a connecting plate assembly including a generally U-shaped cross-section formed by a top portion and a pair of spaced apart side walls, and an adjustment screw operable to move the connecting plate assembly relative to the base plate about a curved region of the connecting plate assembly. The connecting plate assembly has a projection through a curved region to a lower portion of the projection positioned between the side walls and generally parallel to the top portion. The curved region is elastically deflectable to permit the lower and top portions to move relative to each other. The lower portion is adjustably connected to the base plate.
1. An adjustable hinge fixture comprising:
a base plate for adjustable fixation to an article of furniture;
a connecting plate assembly including a generally U-shaped cross-section formed by a top portion and a pair of spaced apart side walls, the connecting plate assembly having a projection through a curved region to a lower portion of the projection positioned between the side walls and generally parallel to the top portion, the curved region being elastically deflectable along a bending axis to permit the lower and top portions to move relative to each other, wherein the lower portion is adjustably connected to the base plate;
a hinge arm pivotably connected to the connecting plate assembly with a first pin having a first longitudinal axis;
a hinge cup pivotably connected to the hinge arm with a second pin having a second longitudinal axis;
wherein the bending axis is generally parallel to the first longitudinal axis and the second longitudinal axis; and,
an adjustment screw operable to move the connecting plate assembly relative to the base plate about the curved region of the connecting plate assembly.
2. The adjustable hinge fixture of claim 1 , wherein the base plate includes an open slot adapted to receive the adjustment screw, the adjustment screw being positioned in a threaded opening of the top portion and adjustably secured within the open slot.
3. The adjustable hinge fixture of claim 2 , wherein the connecting plate assembly includes an eccentric operator configured to allow adjustment of the connecting plate assembly along the base plate in a longitudinal direction.
4. The adjustable hinge fixture of claim 3 , wherein the base plate includes a boss positioned between the U-shaped cross section operatively allowing slideable movement of the connecting plate assembly along the base plate in a longitudinal direction.
5. The adjustable hinge fixture of claim 4 , wherein the eccentric operator is mounted in the lower portion and projects into a hole formed in the base plate, and wherein the eccentric operator is adapted for adjustably connecting the connecting plate assembly to the base plate.
6. The adjustable hinge fixture of claim 5 , wherein the eccentric operator includes a screw head, and wherein an opening formed on the top portion is positioned above the screw head.
7. The adjustable hinge fixture of claim 6 , wherein adjustment of the screw head moves the connecting plate assembly along the base plate in a longitudinal direction.
8. The adjustable hinge fixture of claim 5 , wherein the eccentric operator includes an off-center cam that is secured in the base plate.
9. The adjustable hinge fixture of claim 8 , wherein the off-center cam is riveted in the base plate.
10. The adjustable hinge fixture of claim 8 , wherein the off-center cam is bolted in the base plate.
11. The adjustable hinge fixture of claim 4 , wherein the base plate includes first and second wing portions extending transversely on opposite sides thereof, the first and second wing portions each being adapted for receiving fixing screws for securing the base plate to the article of furniture.
12. The adjustable hinge fixture of claim 11 , wherein the first and second wing portions each include an elongated slot extending transversely and adapted to receive a fixing screw for securing the base plate to the article of furniture and operable to allow adjustment of the base plate in a transverse direction.
13. The adjustable hinge fixture of claim 12 , wherein the first and second wing portions each further include a downward extending flap which is configured to rest against a side of the article of furniture.
14. The adjustable hinge fixture of claim 1 further comprising;
a four-bar linkage having a first end pivotally connected to the connecting plate assembly and a second end pivotally connected to a hinge cup mounted in a door, wherein the adjustable hinge fixture provides an adjustable space between the article of furniture and the door.
15. An adjustable hinge comprising:
an adjustable hinge fixture including:
a base plate for adjustable fixation to a first article of furniture,
a connecting plate assembly including a generally U-shaped cross-section formed by a top portion and a pair of spaced apart side walls, the connecting plate assembly having a projection through a curved region to a lower portion of the projection positioned between the side walls and generally parallel to the top portion, the curved region being elastically deflectable alone a bending axis to permit the lower and top portions to move relative to each other, wherein the lower portion is adjustably connected to the base plate, and
an adjustment screw operable to move the connecting plate assembly relative to the base plate about the curved region of the connecting plate assembly;
a door-related part secured to a second article of furniture;
a linkage means, having a set of pins with a set of parallel longitudinal axes, for movably interconnecting the door-related part and the adjustable hinge fixture; and,
wherein the longitudinal axes of the set of pins and the bending axis are generally parallel.
16. The adjustable hinge of claim 15 , wherein the connecting plate assembly includes an eccentric operator configured to allow adjustment of the connecting plate assembly along the base plate in a longitudinal direction.
17. The adjustable hinge of claim 16 , wherein the base plate includes first and second wing portions extending transversely on opposite sides thereof, the first and second wing portions each including an elongated slot extending transversely and adapted to receive a fixing screw for securing the base plate to the first article of furniture and operable to allow adjustment of the base plate in a transverse direction.
18. The adjustable hinge of claim 15 , wherein the adjustable hinge has an adjustable gap between the first and second articles of furniture and wherein the linkage means further comprises a four-bar linkage.
19. The adjustable hinge of claim 18 , wherein the adjustable hinge comprises a self-closing adjustable hinge.
