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 of the inner casing with respect to the outer casing to adjust an axial height, along a lengthwise axis of the adjustable drop, of the inner casing, wherein the proximal end and the distal end of the inner casing have openings aligned with a longitudinal axis through the outer 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 further comprises 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.

6 . The adjustable drop of claim 1 , wherein the proximal end of the outer casing has internal threading to receive a sprinkler conduit.

7 . The adjustable drop of claim 6 , wherein the sprinkler conduit is a flexible metal conduit directly coupled to the proximal end of the inner casing via the internal threading.

8 . The adjustable drop of claim 1 , wherein the distal end and the proximal end of the outer casing are aligned with the longitudinal axis.

9 . An integral hub and drop assembly comprising:
a bracket hub; and an adjustable drop integrally formed as one piece with the bracket hub, the adjustable drop defining a lengthwise axis, the adjustable drop having openings at distal and proximal ends that align with the lengthwise axis; wherein the bracket hub defines an inverted U-shaped opening offset outboardingly 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.

10 . The integral hub and drop assembly of claim 9 , wherein the U-shaped side opening is integrally coupled to the first side of the adjustable drop.

11 . The integral hub and drop assembly of claim 10 , wherein the U-shaped side opening is welded to the first side of the adjustable drop.

12 . The integral hub and drop assembly of claim 9 , wherein the adjustable drop comprises an inner casing and an outer casing surrounding the inner casing.

13 . The integral hub and drop assembly of claim 12 , 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.
