A door handle lock assembly includes a housing configured to be attached to a door. A interconnecting member is rotatably and axially movably supported by the housing. A first handle is fixed to the interconnecting member at a first end of the interconnecting member and a second handle is fixed to the interconnecting member at a second end of the interconnecting member. The door is between the second handle and the housing. The door handle lock assembly is changed from a locked condition to an unlocked condition by axially moving the interconnecting member from a first position to a second position and then rotating the interconnecting member.

What is claimed is: 1. A door handle lock assembly, comprising: a housing configured to be attached to a door; an interconnecting member rotatably and axially movably supported by the housing; a first handle fixed to the interconnecting member at a first end of the interconnecting member; a second
What is claimed is: 1. A door handle lock assembly, comprising: a housing configured to be attached to a door; an interconnecting member rotatably and axially movably supported by the housing; a first handle fixed to the interconnecting member at a first end of the interconnecting member; a second handle fixed to the interconnecting member at a second end of the interconnecting member, wherein the door is between the second handle and the housing, the door handle lock assembly is changed from a locked condition to an unlocked condition by axially moving the interconnecting member from a first position to a second position and then rotating the interconnecting member, and the first and second handles axially move in unison during axial movement of the interconnecting member from the first position to the second position, and a lock member fixed to the interconnecting member between the first handle and the second handle, the lock member configured to engage the housing to prevent rotation of the interconnecting member when the interconnecting member is in the first position and to disengage from the housing when the interconnecting member is moved from the first position to the second position to permit rotation of the interconnecting member. 2. A door handle lock assembly according to claim 1, further comprising: a spring between the lock member and the housing that biases the interconnecting member into the first position. 3. A door handle lock assembly according to claim 1, wherein the second handle is configured to be received in a recess in the door when the interconnecting member is in the first position. 4. A door handle lock assembly according to claim 3, wherein the recess comprises a first recess having a shape complementary to the shape of the second handle. 5. A door handle lock assembly according to claim 4, wherein the recess further comprises a second recess and/or the second handle includes a recess. 6. A door handle lock assembly according to claim 3, wherein the second handle is configured to be flush with an outer surface of the door when the interconnecting member is in the first position. 7. A door handle lock assembly according to claim 1, wherein the interconnecting member is a shaft. 8. A door handle lock assembly, comprising: a housing configured to be attached to a door; an interconnecting member rotatably and axially movably supported by the housing; a first handle fixed to the interconnecting member at a first end of the interconnecting member; a second handle fixed to the interconnecting member at a second end of the interconnecting member, wherein the door is between the second handle and the housing, and the door handle lock assembly is changed from a locked condition to an unlocked condition by axially moving the interconnecting member from a first position to a second position and then rotating the interconnecting member; a lock member fixed to the interconnecting member between the first handle and the second handle; and a spring between the lock member and the housing that biases the interconnecting member into the first position, wherein the lock member includes a locking projection that engages the housing to prevent rotation of the interconnecting member when the interconnecting member is in the first position and is disengaged from the housing when the interconnecting member is moved from the first position to the second position to permit rotation of the interconnecting member. 9. A door handle lock assembly according to claim 8, further comprising a locking bolt pivotally connected to the locking member. 10. A door handle lock assembly according to claim 9, wherein the locking bolt is pivotally connected to the locking member by the locking projection. 11. A door handle lock assembly according to claim 10, further comprising a locking pin pivotally connected to an end of the locking bolt opposite an end at which the locking bolt is pivotally connected to the locking member. 12. An aircraft including a door and a door handle lock assembly, the door handle lock assembly comprising: a housing configured to be attached to the door; a interconnecting member rotatably and axially movably supported by the housing; a first handle fixed to the interconnecting member at a first end of the interconnecting member a second handle fixed to the interconnecting member at a second end of the interconnecting member, wherein the door is between the second handle and the housing, the door handle lock assembly is changed from a locked condition to an unlocked condition by axially moving the interconnecting member from a first position to a second position and then rotating the interconnecting member, and the first and second handles axially move in unison during axial movement of the interconnecting member from the first position to the second position, and a lock member fixed to the interconnecting member between the first handle and the second handle, the lock member configured to engage the housing to prevent rotation of the interconnecting member when the interconnecting member is in the first position and to disengage from the housing when the interconnecting member is moved from the first position to the second position to permit rotation of the interconnecting member. 13. An aircraft according to claim 12, further comprising: a spring between the lock member and the housing that biases the interconnecting member into the first position. 14. An aircraft according to claim 12, wherein the second handle is configured to be received in a recess in the door when the interconnecting member is in the first position. 15. An aircraft according to claim 14, wherein the recess comprises a first recess having a shape complementary to the shape of the second handle. 16. An aircraft according to claim 15, wherein the recess further comprises a second recess and/or the second handle includes a recess. 17. An aircraft according to claim 14, wherein the second handle is configured to be flush with an outer surface of the door when the interconnecting member is in the first position. 18. An aircraft according to claim 12, wherein the interconnecting member is a shaft. 19. An aircraft comprising: a door; and a door handle lock assembly comprising: a housing configured to be attached to the door; a interconnecting member rotatably and axially movably supported by the housing; a first handle fixed to the interconnecting member at a first end of the interconnecting member; a second handle fixed to the interconnecting member at a second end of the interconnecting member, wherein the door is between the second handle and the housing, the door handle lock assembly is changed from a locked condition to an unlocked condition by axially moving the interconnecting member from a first position to a second position and then rotating the interconnecting member; a lock member fixed to the interconnecting member between the first handle and the second handle; and a spring between the lock member and the housing that biases the interconnecting member into the first position, wherein the lock member includes a locking projection that engages the housing to prevent rotation of the interconnecting member when the interconnecting member is in the first position and is disengaged from the housing when the interconnecting member is moved from the first position to the second position to permit rotation of the interconnecting member. 20.
