Abstract

A method of installing a toilet system on board an aircraft is generally described. The toilet system includes a base support having a right base support and a left base support, a toilet bowl, a right side support and a left side support each supporting the toilet bowl. The method comprises lowering the toilet bowl on to the base supports to at least partially engage a first locking mechanism; sliding the toilet bowl in a forward direction to engage a second locking mechanism; and inserting a first pin to couple the right base support to the right side support and a second pin to couple the left base support to the left side support in order to completely engage the first locking mechanism.

First claim

The invention claimed is:

1. A toilet system configured for use on board an aircraft comprising:
a base support mounted on the aircraft, the base support including a right base support and a left base support;
a toilet bowl;
a right side support and a left side support each supporting the toilet bowl;
a first locking mechanism configured to secure the toilet bowl to the aircraft by coupling the right base support to the right side support and coupling the left base support to the left side support, the first locking mechanism comprising:
a tab provided on each of the left base support and the right base support, each tab having a through-hole and end portion of each of the left side support and the right side support having a corresponding through-hole;
a corresponding cavity on an end face of each of the left side support and the right side support, each tab configured to be inserted into the respective cavity on the end faces of each of the left side support and the right side support; and
a first pin configured to be inserted through the through-hole on i) one of the left side support and the right side support, and the through-hole on the tab on ii) one of the left base support and the right base support; and

a second locking mechanism configured to secure the toilet bowl to the aircraft by coupling the right base support to the right side support and coupling the left base support to the left side support; wherein
the first locking mechanism and the second locking mechanism operate independent of each other.

2. The toilet system according to claim 1 , wherein the first locking mechanism further comprises:
a second pin configured to be inserted through the through-hole on i) the other of the left side support and right side support; and the through-hole on the tab on ii) the other of the left base support and the right base support.

3. The toilet system according to claim 2 , wherein the first pin and the second pin are a hitch pin.

4. The toilet system according to claim 1 , wherein the tabs are provided at a rear portion of the respective left base support and the right base support.

5. The toilet system according to claim 1 , wherein the second locking mechanism comprises:
a right side protrusion extending from an end of the right side support and a left side protrusion extending from an end of the left side support; and
a respective locking receptacle positioned on each of the right base support and the left base support and corresponding to the right side protrusion and the left side protrusion; wherein
the right side protrusion and the left side protrusion are configured to be inserted into the respective locking receptacles.

6. A method of installing a toilet system on board an aircraft, the toilet system including a base support mounted on the aircraft, the base support having a right base support and a left base support, a toilet bowl, a right side support and a left side support each supporting the toilet bowl, the method comprising:
lowering the toilet bowl supported by the left side support and the right side support on to the left base support and the right base support respectively to at least partially engage a first locking mechanism;
sliding the toilet bowl supported by the left side support and the right side support in a forward direction to engage a second locking mechanism; and

inserting a first pin to couple the right base support to the right side support and a second pin to couple the left base support to the left side support in order to completely engage the first locking mechanism.

7. The method according to claim 6 , wherein the first locking mechanism comprises:
a tab provided on each of the left base support and the right base support; and
a corresponding cavity on an end face of each of the left side support and the right side support;
wherein at least partially engaging the first locking mechanism comprises

aligning the tab with the respective cavity on the end faces of each of the left side support and the right side support; and
inserting the tab into the respective cavity on the end faces of each of the left side support and the right side support.

8. The method according to claim 7 , wherein the tab on each of the left base support and the right base support has a through-hole; and
an end portion of each of the left side support and the right side support has a corresponding through-hole; and
wherein completely engaging the first locking mechanism further comprises
inserting the first pin through the through-hole on the right side support and the through-hole on the tab on the right base support; and
inserting the second pin through the through-hole on the left side support and the through-hole on the tab on the left base support.

9. The method according to claim 6 , wherein the first pin and the second pin are a hitch pin.

10. The method according to claim 7 , wherein the tabs are provided at a rear portion of the respective left base support and the right base support.

11. The method according to claim 6 , wherein the second locking mechanism comprises:
a right side protrusion extending from an end of the right side support and a left side protrusion extending from an end of the left side support; and
a respective locking receptacle positioned on each of the right base support and the left base support and corresponding to the right side protrusion and the left side protrusion;
wherein engaging the second locking mechanism comprises
inserting the right side protrusion and the left side protrusion into the respective locking receptacles by sliding the right side support and the left side support in a forward direction.

12. A toilet system configured for use on board an aircraft comprising:
a base support mounted on the aircraft;
a toilet bowl;
a side support configured to support the toilet bowl;
a first locking mechanism configured to secure the toilet bowl to the aircraft by coupling the base support to the side support, the first locking mechanism comprising:
a tab provided on the base support; and
a corresponding cavity on an end face of the side support, wherein the tab is configured to be inserted into the respective cavity on the end face of the side support;
wherein the tab on the base support has a through-hole, an end portion of the side support has a corresponding through-hole, and the first locking mechanism further comprises a pin configured to be inserted through the through-hole on the side support and the through-hole on the tab on the base support; and

a second locking mechanism configured to secure the toilet bowl to the aircraft by coupling the base support to the side support; wherein the first locking mechanism and the second locking mechanism operate independent of each other.

13. The toilet system according to claim 12 , wherein the second locking mechanism comprises:
a protrusion extending from an end of the side support; and
a locking receptacle positioned on the base support and corresponding to the protrusion; wherein
the protrusion is configured to be inserted into the locking receptacle.
