Abstract

A printhead includes a printhead housing and a handle. The handle is movably coupled to the printhead housing. The handle rotatably moves with respect to the printhead housing between a folded position and the non-folded position. In the folded position, the handle extends along a respective housing surface of the printhead housing. In the non-folded position, the handle extends outward from the respective housing surface of the printhead housing.

First claim

What is claimed is:

1. A printhead comprising:
a printhead housing;
a handle movably coupled to the printhead housing, the handle to rotatably move with respect to the printhead housing between a folded position in which the handle extends along a respective housing surface of the printhead housing and a non-folded position in which the handle extends outward from the respective housing surface of the printhead housing; and
wherein the handle in the non-folded position is configured to be accessed by a user to removably move the printhead housing into and out of a printer; and
a plurality of resilient members that bias the handle in two opposing directions to an intermediate position between the folded position and an upright position.

2. The printhead of claim 1 , wherein a folded angle formed by the handle and the respective housing surface of the printhead housing in a folded position is about zero degrees.

3. The printhead of claim 1 , wherein a non-folded angle formed by the handle and the respective housing surface of the printhead housing in the non-folded position is in a range of 25 degrees to 75 degrees.

4. The printhead of claim 1 , wherein the resilient member comprises both a lift spring to provide a force to bias the handle away from the folded position to the non-folded position and a return spring to provide a force to bias the handle away from the upright position to the intermediate position.

5. The printhead of claim 1 , wherein the handle is U-shaped.

6. The printhead of claim 1 , wherein the printhead housing comprises: a removable printhead cartridge including a nozzle surface on one end thereof and the respective housing surface on another end thereof.

7. A printhead installed in a printer comprising:
a printhead housing including a removable printhead cartridge removably inserted into the printer; and
a handle movably coupled to the printhead housing, the handle to rotatably move with respect to the printhead housing between an upright position, an intermediate position, and a folded position;
the folded position corresponds to the handle extending along a respective housing surface of the printhead housing;
the upright position corresponds to the handle extending outward from the respective housing surface of the printhead housing and forming a first non-folded angle with the respective housing surface; and
the intermediate position corresponds to the handle extending outward from the respective housing surface of the printhead housing and forming a second non-folded angle with the respective housing surface less than the first non-folded angle;
a resilient member to bias the handle away from the folded position; and
a cover that, when closed, forces the handle into the folded position against the bias;
wherein the handle in a non-folded position is configured to be accessed by a user to removably move the printhead housing into and out of a printer.

8. The printhead of claim 7 , wherein the first non-folded angle is about 90 degrees.

9. The printhead of claim 7 , herein the second non-folded angle is in a range of 25 to 75 degrees.

10. The printhead of claim 7 , wherein a folded angle formed by the handle and the respective housing surface of the printhead housing in a folded position is about zero degrees.

11. The printhead of claim 7 , wherein the resilient member comprises a lift spring to lift the handle from the folded position to the intermediate position.

12. The printhead of claim 11 , wherein the lift spring comprises:
a first lift leg portion to contact the handle;
a second lift leg portion to contact the printer; and
a lift intermediate portion to contact the handle disposed between the first lift leg portion and the second lift leg portion.

13. The printhead of claim 11 , wherein the resilient member further comprises a return spring to push the handle from the upright position to the intermediate position.

14. The printhead of claim 13 , wherein the return spring comprises:
a first return leg portion to contact the handle;
a second return leg portion to contact the printer, and
a return intermediate portion to contact the handle disposed between the first return leg portion and the second return leg portion.

15. The printhead of claim 7 , further comprising: a lift spring and a return spring to provide forces to bias the handle to the intermediate position to be accessed by the user to remove the removable cartridge from the printer.

16. The printhead of claim 1 , wherein the resilient member comprises:
a lift spring to bias the handle away from the folded position toward the intermediate position; and
a return spring, opposing the lift spring, to bias the handle from the upright position toward the intermediate position.

17. The printhead of claim 16 , wherein:
the return spring comprises
a first return leg portion to contact the handle;
a second return leg portion, having a U-shape, to contact a printer, and
a return intermediate portion to contact the handle disposed between the first return leg portion and the second return leg portion; and

the lift spring comprises
a first lift leg portion to contact the handle;
a second lift leg portion to contact the printer; and
a lift intermediate portion to contact the handle disposed between the first lift leg portion and the second lift leg portion, wherein the second lift leg portion wraps around a portion of the first lift leg adjacent the lift intermediate portion.

18. The printhead of claim 1 , wherein a weight of the printhead causes the handle, when pulled by a user, to extend to the upright position to provide tactile feedback to the user.

19. The printhead of claim 7 , wherein the resilient member biases the handle in two opposing directions to the intermediate position between the folded position and the upright position.

20. The printhead of claim 7 , wherein a weight of the printhead causes the handle, when pulled by a user, to extend to the upright position to provide tactile feedback to the user.
