Abstract

A vehicular airflow outlet comprising a plurality of outlet units having an airflow unit, a ball joint, and a connection member; a control knob unit including a control knob coupled to a ball joint; and a connection mechanism configured to couple the ball joint of the each of the outlet units and the ball joint of the control knob unit is provided. The airflow outlet allows for the direction of airflow throughout a vehicle passenger compartment without the use of multiple sets of vanes. The airflow outlet directs airflow through the use of a single control knob. Force applied to the face of the control knob is operable to simultaneously pivot the ball joints of each of the plurality of outlet units and the ball joint of the control knob unit in unison to adjust airflow direction, allowing for the direction of air at a variety of angles.

First claim

The invention claimed is:

1. A vehicular airflow outlet comprising:
a plurality of outlet units, each outlet unit including:
an airflow unit defining a cavity;
a connection member disposed within the cavity;
a ball portion coupled to the connection member;
a first interlocking portion defining a cavity therein for receiving the airflow unit, the first interlocking portion having a first plurality of retention features;
a second interlocking portion defining a cavity therein for receiving the airflow unit, the second interlocking portion having a second plurality of retention features configured to engage the first plurality of retention features to couple the first interlocking portion and the second interlocking portion;

a control knob unit including a control knob having a first face side and a second connection side, the control knob unit further including a ball portion coupled to the second connection side;
a connection mechanism configured to couple the ball portion of the each of the outlet units and the ball portion of the control knob unit; and
wherein the direction of air flowing through the vehicular airflow outlet is controlled by a force applied to the first face side of the control knob, such that the force applied to the first face side of the control knob is transitioned to the ball portion of the control knob unit and the ball portion of each the plurality of outlet units through the connection mechanism, such that the ball portion of each of the plurality of outlet units and the ball portion of the control knob unit are rotated in unison to adjust airflow direction.

2. The vehicular airflow outlet of claim 1 wherein the connection mechanism further includes:
a plurality of joint sockets, each of the respective joint sockets configured to receive one of the ball portion of one of the outlet units and the ball portion of the control knob unit;
a bracket interlocking array configured to interconnect and couple each of the respective joint sockets.

3. The vehicular airflow outlet of claim 2 wherein an interconnection of the joint socket which houses the ball portion of the control knob unit and the bracket interlocking array is reinforced with an overmold or bracket.

4. The vehicular airflow outlet of claim 3 wherein the overmold or bracket is formed of a polymeric material.

5. The vehicular airflow outlet of claim 1 wherein the control knob unit further includes:
a first interlocking portion defining a cavity therein for receiving the control knob, the first interlocking portion having a first plurality of retention features extending from the first interlocking portion;
a second interlocking portion defining a cavity therein for receiving the control knob, the second interlocking portion having a second plurality of retention features configured to engage the first plurality of retention features to couple the first interlocking portion and the second interlocking portion; and
wherein the first plurality of retention features and second plurality of retention features of each of the respective outlet units and the control knob unit are arranged in an interlocking engagement forming an outlet array.

6. The vehicular airflow outlet of claim 5 wherein the at least one outlet further comprises:
a trim plate defining an interior void, the trim plate configured to encase the outlet array;
a housing defining a cavity therein, the cavity configured to receive the outlet array and the trim plate.

7. The vehicular airflow outlet of claim 5 wherein each of the first interlocking portion and the second interlocking portion of each of the outlet units and the first interlocking portion and second interlocking portion of the control knob unit are formed in the shape of any even sided polygon having at least four sides.

8. The vehicular airflow outlet of claim 7 wherein each of the first interlocking portion and the second interlocking portion of each of the outlet units and the first interlocking portion and second interlocking portion of the control knob unit are formed in the shape of a square.

9. The vehicular airflow outlet of claim 7 wherein each of the first interlocking portion and the second interlocking portion of each of the outlet units and the first interlocking portion and second interlocking portion of the control knob unit are formed in the shape of a hexagon.

10. The vehicular airflow outlet of claim 7 wherein each of the first interlocking portion and the second interlocking portion of each of the outlet units and the first interlocking portion and second interlocking portion of the control knob unit are formed in the shape of an octagon.

11. The vehicular airflow outlet of claim 7 wherein each of the first interlocking portion and the second interlocking portion of each of the outlet units and the first interlocking portion and second interlocking portion of the control knob unit are formed in the shape of a decagon.

12. The vehicular airflow outlet of claim 1 wherein each of the airflow units, the ball portion, and the connection member of each of the respective outlet units are formed of a polymeric material.

13. The vehicular airflow outlet of claim 1 wherein each of the first interlocking portion and the second interlocking portion of each of the respective outlet units are formed of a polymeric material.

14. The vehicular airflow outlet of claim 5 wherein each of the control knob, ball portion, first interlocking portion, and the second interlocking portion of the control knob unit are formed of a polymeric material.

15. The vehicular airflow outlet of claim 2 wherein each of the joint sockets and the bracket interlocking array are formed of a polymeric material.

16. A vehicle having a passenger compartment comprising:
a plurality of airflow outlets including:
a plurality of outlet units, each outlet unit including:
an airflow unit defining a cavity;
a connection member disposed within the cavity;
a ball portion coupled to the connection member;
a first interlocking portion defining a cavity therein for receiving the airflow unit, the first interlocking portion having a first plurality of retention features;
a second interlocking portion defining a cavity therein for receiving the airflow unit, the second interlocking portion having a second plurality of retention features configured to engage the first plurality of retention features to couple the first interlocking portion and the second interlocking portion;

a control knob unit including a control knob having a first face side and a second connection side, the control knob unit further including a ball portion coupled to the second connection side;
a connection mechanism configured to couple the ball portion of each outlet unit and the ball joint of the control knob unit; and
wherein the direction of airflow flowing through the airflow units is controlled by a force applied to the first face side of the control knob, the force applied to the first face side being operable to simultaneously pivot the ball portions of each of the plurality of outlet units and the ball portion of the control knob unit in unison to adjust airflow direction.

17. The vehicle of claim 16 wherein the connection mechanism further includes:
a plurality of joint sockets, each of the respective joint sockets configured to receive one of the ball joint of one of the outlet units and the ball joint of the control knob unit;
