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 assembly comprising:
a housing;
a printhead coupled with the housing, the printhead having a nozzle surface; and
a handle movably coupled to the housing, the handle to rotatably move with respect to the housing between a folded position in which the handle extends along a respective housing surface of the housing and a non-folded position in which the handle extends outward from the respective housing surface of the housing; 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 assembly of claim 1 , wherein a folded angle formed by the handle and the respective housing surface of the housing in a folded position is about zero degrees.

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

4. The printhead assembly of claim 1 , wherein the plurality of resilient members 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 assembly of claim 1 , wherein the handle is accessible by a user to removably move the housing, the housing being moved with the handle attached thereto, into and out of a printer when the handle is in the non-folded position.

6. The printhead assembly of claim 1 , wherein the printhead comprising a printhead cartridge that is removably coupled with the housing.

7. The printhead assembly of claim 1 , wherein the plurality of resilient members comprise:
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.

8. The printhead assembly of claim 7 , 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.

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

10. A printhead assembly installed in a printer comprising:
the printhead assembly comprising a housing and a removable printhead cartridge installed on the housing, the printhead cartridge comprising a nozzle surface, the printhead assembly being removably installed in the printer;
the printhead assembly further comprising a handle movably coupled to the housing, the handle to rotatably move with respect to the housing between an upright position, an intermediate position, and a folded position,
wherein:
the folded position corresponds to the handle extending along a respective housing surface of the housing;
the upright position corresponds to the handle extending outward from the respective housing surface of the 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 housing and forming a second non-folded angle with the respective housing surface less than the first non-folded angle;
the printhead assembly further comprising a resilient member to bias the handle away from the folded position, wherein the resilient member comprises a lift spring to lift the handle from the folded position to the intermediate position, biasing the handle to the intermediate position; and
the printer comprising 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.

11. The printhead assembly of claim 10 , wherein the first non-folded angle is about 90 degrees.

12. The printhead assembly of claim 10 , wherein the second non-folded angle is in a range of 25 to 75 degrees.

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

14. The printhead assembly of claim 10 , 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.

15. The printhead assembly of claim 10 , wherein the resilient member further comprises a return spring to push the handle from the upright position to the intermediate position.

16. The printhead assembly of claim 15 , wherein the return spring comprises:
a first return leg portion to contact the handle;
a second return leg portion, and
a return intermediate portion to contact the handle disposed between the first return leg portion and the second return leg portion.

17. The printhead assembly of claim 10 , further comprising: a lift spring and a return spring to provide opposing forces to bias the handle to the intermediate position to be accessed by the user to remove the removable cartridge from the printer.

18. The printhead assembly of claim 10 , wherein the resilient member biases the handle in two opposing directions to the intermediate position between the folded position and the upright position.

19. The printhead assembly of claim 10 , wherein a weight of the printhead assembly causes the handle, when pulled by a user, to extend to the upright position to provide tactile feedback to the user.
