Imaging unit having a pivoting, collapsible handle
View Patent ↗An imaging unit of an image forming apparatus is provided including a handle mechanism. The imaging unit includes at least one of a photoconductor unit and a developer unit for developing a toner on the photoconductor unit. The handle mechanism is mounted on a frame portion of the housing and is configured to pivot between a collapsed position and an extended position. When in the collapsed position, the handle mechanism is substantially flush with a surface of the housing to accommodate a toner cartridge. When in the extended position, the handle mechanism automatically returns to the collapsed position by gravity when released from a user's grip.
1. A removable unit of an imaging device, comprising:
at least one of a photoconductor unit and a developer unit for developing a toner on the photoconductor unit;
a housing for holding the at least one of the photoconductor unit and the developer unit, wherein the housing includes a frame portion; and
a handle mechanism mounted on the frame portion and configured to pivot between a collapsed position and an extended position, the handle mechanism including,
a handle member having a gripping segment and a plurality of side segments, each side segment being attached to and extending from the gripping segment and pivotably connecting the handle member to the frame portion; and
a plurality of arms, each arm pivotably engaging with the handle member and slidably mounting to the frame portion;
wherein in the collapsed position, the handle member, side segments and arms are substantially flush with a surface of the frame portion.
2. The removable unit of claim 1 , wherein each side segment includes a first coupling mechanism for connecting to the frame portion, and the frame portion including a plurality of apertures for receiving the first coupling mechanism of the side segments.
3. The removable unit of claim 1 , wherein each side segment includes a first coupling mechanism for connecting to the frame portion, each first coupling mechanism includes a first tab extending therefrom and the frame portion includes a plurality of apertures for receiving the first coupling mechanisms of the side segments, each aperture having a slot configured to receive the corresponding first tab to prevent disconnection of the handle member from the frame portion.
4. The removable unit of claim 1 , wherein each arm includes a second coupling mechanism on a first end thereof for engaging with the handle member, and a third coupling mechanism on a second end of the arm for connecting to the frame portion, the frame portion including track members for slidingly receiving the third coupling mechanism of the arms.
5. The removable unit of claim 1 , the extended position being defined by a first angle and a second angle, the first angle being an angle between the handle member and the frame portion, the second angle being an angle between at least one of the arms and the handle member, wherein at least one of the first and the second angles is an acute angle.
6. The removable unit of claim 5 , wherein the first angle is between about 25 degrees and about 35 degrees.
7. The removable unit of claim 5 , wherein the second angle is greater than 90 degrees.
8. The removable unit of claim 1 , wherein each arm includes a second coupling mechanism on a first end thereof for engaging with the handle member, and a third coupling mechanism on a second end of the arm for connecting to the frame portion, each second coupling mechanism includes a second tab to prevent disconnection of the arms from the handle member, and the handle member includes a plurality of apertures for receiving the second coupling mechanisms, each aperture including a slot configured to receive the second tab.
9. The removable unit of claim 1 , wherein each arm includes a second coupling mechanism on a first end thereof for engaging with the handle member, each second coupling mechanism includes a second tab and the handle member includes a plurality of apertures for receiving the second coupling mechanisms, and each aperture including a slot configured to receive the second tab to prevent disconnection of the arms from the handle member.
10. The removable unit of claim 2 , wherein the gripping segment extends substantially between two side segments towards the first coupling mechanisms to prevent a user's thumb from being slid underneath the gripping segment when in the extended position.
11. The removable unit of claim 1 , wherein one side of the gripping segment is bowed in a central portion thereof for facilitating initial grasping by a user of the gripping segment when the handle mechanism is in the collapsed position.
12. The removable unit of claim 1 , wherein the handle mechanism automatically returns to the collapsed position by gravity when released from a user's grip.
13. The removable unit of claim 1 , wherein the gripping segment includes at least one indention for engaging with a tip of a finger of a user for facilitating initial lifting of the handle member from the collapsed position to the extended position.
14. A handle mechanism mounted on a consumable item of an imaging device and configured to pivot between a collapsed position and an extended position, comprising:
a handle member pivotably connected to a frame portion of a housing of a consumable item; and
at least one arm pivotably engaging with the handle member and slidingly engaged with the frame portion;
wherein in the collapsed position, the handle member and the at least one arm are substantially flush with a surface of the housing.
15. The handle mechanism of claim 14 , wherein the at least one arm includes a first end coupled to the handle member and a second end, and the frame portion includes a track for receiving the second end of the at least one arm.
16. The handle mechanism of claim 14 , wherein the handle member and the at least one arm define a first angle and a second angle, the first angle being an angle between the handle member and the frame portion, the second angle being an angle between the at least one arm and the handle member, the first angle varying between about 25 degrees to about 35 degrees between the extended position and the collapsed position.
17. The handle mechanism of claim 16 , wherein the first angle is from about 25 degrees to about 35 degrees when the handle member is in the extended position and about zero degrees when in the collapsed position.
18. The handle mechanism of claim 16 , wherein the second angle is greater than 90 degrees when the handle member is in the extended position and about 180 degrees when in the collapsed position.
19. The handle mechanism of claim 14 , wherein the handle member includes a substantially planar member to prevent a user's thumb from being slid underneath the handle member when in the extended position.
20. The handle mechanism of claim 14 , wherein the handle member is bowed in a central portion thereof for facilitating initial grasping by a user when the handle mechanism is in the collapsed position.
21. The handle mechanism of claim 14 , wherein the handle mechanism automatically returns to the collapsed position by gravity when released from a user's grip.
