Abstract

A modular door kit for a vehicle HVAC system includes first, second, and third subcomponents. The first subcomponent defines a receptacle and is configured to be standardized for first and second door configurations. The second subcomponent has a first protrusion and is configured to be standardized for the first door configuration but not the second door configuration. The first protrusion is configured to engage the receptacle to rigidly affix the position of the second subcomponent relative to the first subcomponent to form the first door configuration. The third subcomponent has a second protrusion and is configured to be standardized for the second door configuration but not the first door configuration. The second protrusion is configured to engage the receptacle to rigidly affix the position of the third subcomponent relative to the first subcomponent to form the second door configuration.

First claim

What is claimed is:

1 . A modular door kit for a vehicle HVAC system comprising:
a first subcomponent defining a keyed receptacle and configured to be standardized for first and second door configurations; a second subcomponent having a first keyed protrusion and configured to be standardized for the first door configuration but not the second door configuration, wherein the first keyed protrusion is configured to engage the keyed receptacle to rigidly affix the position of the second subcomponent relative to the first subcomponent to form the first door configuration; and a third subcomponent having a second keyed protrusion and configured to be standardized for the second door configuration but not the first door configuration, wherein the second keyed protrusion is configured to engage the keyed receptacle to rigidly affix the position of the third subcomponent relative to the first subcomponent to form the second door configuration.

2 . The modular door kit for a vehicle HVAC system of claim 1 , wherein the engagement between first keyed protrusion or the second keyed protrusion and the keyed receptacle forms a pivot shaft.

3 . The modular door kit for a vehicle HVAC system of claim 1 , wherein the first subcomponent includes a first plate and the second subcomponent includes a second plate, and wherein engagement between the first keyed protrusion and the keyed receptacle is configured to orient the first plate relative to the second plate such that the first plate and the second plate are parallel.

4 . The modular door kit for a vehicle HVAC system of claim 3 , wherein the third subcomponent includes a third plate, and wherein engagement between the second keyed protrusion and the keyed receptacle is configured to orient the first plate relative to the third plate such that an angle between the first plate and the third plate is less than 180°.

5 . The modular door kit for a vehicle HVAC system of claim 3 , wherein the third subcomponent includes a third plate, and wherein engagement between the second keyed protrusion and the keyed receptacle is configured to orient the first plate relative to the third plate such that an angle between the first plate and the third plate is less than 90°.

6 . The modular door kit for a vehicle HVAC system of claim 1 , wherein the second subcomponent includes a plate and a pivot shaft disposed at a proximal end of the plate, and wherein the first keyed protrusion is disposed on the plate between the pivot shaft and a distal end of plate.

7 . The modular door kit for a vehicle HVAC system of claim 1 , wherein the first subcomponent is a flag type door and the second subcomponent is a barrel type door.

8 . A modular door kit for a vehicle HVAC system comprising:
a first subcomponent having a keyed protrusion and configured to be standardized for first and second door configurations; a second subcomponent defining a first keyed receptacle and configured to be standardized for the first door configuration but not the second door configuration, wherein the keyed protrusion is configured to engage the first keyed receptacle to rigidly affix the position of the second subcomponent relative to the first subcomponent to form the first door configuration; and a third subcomponent defining a second keyed receptacle and configured to be standardized for the second door configuration but not the first door configuration, wherein the keyed protrusion is configured to engage the second keyed receptacle to rigidly affix the position of the third subcomponent relative to the first subcomponent to form the second door configuration.

9 . The modular door kit for a vehicle HVAC system of claim 8 , wherein the engagement between keyed protrusion and the first keyed receptacle or the second keyed receptacle forms a pivot shaft.

10 . The modular door kit for a vehicle HVAC system of claim 8 , wherein the first subcomponent includes a first plate and the second subcomponent includes a second plate, and wherein engagement between the keyed protrusion and the first keyed receptacle is configured to orient the first plate relative to the second plate such that the first plate and the second plate are parallel.

11 . The modular door kit for a vehicle HVAC system of claim 10 , wherein the third subcomponent includes a third plate, and wherein engagement between the keyed protrusion and the second keyed receptacle is configured to orient the first plate relative to the third plate such that an angle between the first plate and the third plate is less than 180°.

12 . The modular door kit for a vehicle HVAC system of claim 10 , wherein the third subcomponent includes a third plate, and wherein engagement between the keyed protrusion and the second keyed receptacle is configured to orient the first plate relative to the third plate such that an angle between the first plate and the third plate is less than 90°.

13 . The modular door kit for a vehicle HVAC system of claim 8 , wherein the first subcomponent includes a plate and a shaft disposed at a proximal end of the plate, and wherein the keyed protrusion is disposed on the plate between the shaft and a distal end of plate.

14 . The modular door kit for a vehicle HVAC system of claim 8 , wherein the first subcomponent is a flag type door and the second subcomponent is a barrel type door.

15 . A method of producing a modular door for a vehicle HVAC system comprising:
producing a first subcomponent defining a receptacle and configured to be standardized for first and second door configurations; producing a second subcomponent having a first protrusion and configured to be standardized for the first door configuration but not the second door configuration; and producing a third subcomponent having a second protrusion and configured to be standardized for the second door configuration but not the first door configuration.

16 . The method of claim 15 further comprising:
inserting the first protrusion into the receptacle to rigidly affix the first subcomponent to the second subcomponent and to form the first door configuration.

17 . The method of claim 15 further comprising:
inserting the second protrusion into the receptacle to rigidly affix the third subcomponent to the first subcomponent and to form the second door configuration.

18 . The method of claim 15 further comprising:
producing a fourth subcomponent defining a second receptacle and configured to be standardized for third and fourth door configurations.

19 . The method of claim 18 further comprising:
inserting the first protrusion into the second receptacle to rigidly affix the fourth subcomponent to the second subcomponent and to form the third door configuration.

20 . The method of claim 18 further comprising:
inserting the second protrusion into the second receptacle to rigidly affix the fourth subcomponent to the third subcomponent and to form the fourth door configuration.
