Abstract

An adjustable drop includes an inner casing, the inner casing comprising: a distal end; a proximal end opposite the distal end, the proximal end comprising a shouldered segment; and a threaded segment between the distal end and the proximal end, the threaded segment starting at the shouldered segment and extending along the inner casing towards the distal end, the shouldered segment defining an outer radius that is greater than an outer radius of the threaded segment; and an outer casing surrounding the inner casing, the inner casing and the outer casing including corresponding threading to permit rotation between the inner casing and the outer casing to adjust an axial height, along a lengthwise axis of the adjustable drop, of the inner casing.

First claim

What is claimed is:

1 . An adjustable drop comprising:
an inner casing, the inner casing comprising:
a distal end;
a proximal end opposite the distal end, the proximal end comprising a shouldered segment; and
a threaded segment between the distal end and the proximal end, the threaded segment starting at the shouldered segment and extending along the inner casing towards the distal end, the shouldered segment defining an outer radius that is greater than an outer radius of the threaded segment; and
an outer casing surrounding the inner casing, the inner casing and the outer casing including corresponding threading to permit rotation between the inner casing and the outer casing to adjust an axial height, along a lengthwise axis of the adjustable drop, of the inner casing.

2 . The adjustable drop of claim 1 , wherein the outer casing further comprises a proximal end, a distal end, and an inner surface, and wherein the inner surface comprises a distal shoulder configured to contact the shouldered segment of the inner casing and to prevent the inner casing from being released out the distal end of the outer casing.

3 . The adjustable drop of claim 2 , wherein the threading of the inner casing is provided on an outer surface of the inner casing, and wherein the threading of the outer casing is provided on the inner surface of the outer casing.

4 . The adjustable drop of claim 2 , wherein the inner casing is a gasket, the gasket including a set of O-rings in contact with the inner surface of the outer casing.

5 . The adjustable drop of claim 1 , further comprising a keying feature formed in a distal end of the adjustable drop, the keying feature configured to receive a device for rotating the inner casing or the outer casing.

6 . An adjustable drop comprising:
an inner casing comprising:
an expandable component;
a first tube; and
a second tube, wherein the expandable component extends between the first and second tubes, and wherein the expandable component permits movement of the first tube relative to the second tube along a lengthwise axis of the adjustable drop; and
an outer casing surrounding the inner casing.

7 . The adjustable drop of claim 6 , wherein the inner casing and the outer casing include corresponding threading to permit rotation between the inner casing and the outer casing to adjust an axial height, along the lengthwise axis, of the inner casing.

8 . The adjustable drop of claim 6 , wherein the inner casing comprises a bellow, the bellow comprising the expandable component disposed within an interior cavity of the outer casing.

9 . The adjustable drop of claim 8 , wherein the outer casing comprises a side wall extending between a first end wall and a second end wall.

10 . The adjustable drop of claim 9 , wherein a distal end of the bellow includes a support ring at an intersection of the bellow and the second tube.

11 . The adjustable drop of claim 10 , wherein the support ring is positioned directly adjacent an interior surface of the second end wall of the outer casing, and wherein the interior surface of the second end wall engages the support ring to move the second tube towards the first tube.

12 . The adjustable drop of claim 8 , wherein the bellow comprises a metal material and defines a plurality of screw-shaped corrugations.

13 . An integral hub and drop assembly comprising:
a bracket hub; and an adjustable drop integrally formed with the bracket hub, the adjustable drop defining a lengthwise axis; wherein the bracket hub defines an inverted U-shaped opening offset to a first side of the lengthwise axis, the inverted U-shaped opening configured to receive a bracket bar, and wherein the bracket hub further defines a U-shaped side opening transverse to the inverted U-shaped opening, the adjustable drop extending through the U-shaped side opening.

14 . The integral hub and drop assembly of claim 13 , wherein the U-shaped side opening is integrally coupled to the first side of the adjustable drop.

15 . The integral hub and drop assembly of claim 14 , wherein the U-shaped side opening is welded to the first side of the adjustable drop.

16 . The integral hub and drop assembly of claim 13 , wherein the adjustable drop comprises an inner casing and an outer casing surrounding the inner casing.

17 . The integral hub and drop assembly of claim 16 , wherein each of the inner casing and the outer casing include corresponding threading configured to permit rotation between the inner casing and the outer casing to adjust an axial height of the inner casing along the lengthwise axis.
