Abstract

Examples of a hinge set for used for mounting a protractible component of a device are described herein. In an example, the hinge set comprises a support hinge and a guide hinge, each having a first end and a second end. The first end of the support hinge is to pivotably couple to the protractible component and the second end of the support hinge is pivotably coupled to a frame of the device. Further, the first end of the guide hinge is to guide the protractile component and the second end of the guide hinge is to pivotably couple to the frame.

Claims

1. A protractible component for a device, the protractible component comprising:

a body portion comprising a hinging edge having a mounting member to hinge the body portion to a frame of the device; and

a hinge set coupled to the body portion to hinge the body portion to the frame, the hinge set comprising;

a support hinge comprising a first end and a second end, wherein the first end of the support hinge is to be pivotably mounted at a fixed position on the frame and the second end of the support hinge is to pivotably couple at a fixed position on the mounting member of the body portion;

a guide hinge comprising a first end and a second end, wherein the first end of the guide hinge is to cooperate with the mounting member to guide the mounting member, and the second end of the guide hinge is to pivotably couple at a fixed position on the frame;

an elastic member to couple the body portion to the hinge set, wherein the elastic member is to protract the protractible component; and

a damping element to couple the body portion to the hinge set, wherein the damping element is to control protraction by the elastic member.

2. The protractible component as claimed in claim 1, wherein the mounting member comprises a groove to cooperate with a follower at the first end of the guide hinge.

3. The protractible component as claimed in claim 1, wherein the body portion comprises a locking edge having a latching member to detachably latch the body portion to the frame when the protractible component is retracted.

4. The protractible component as claimed in claim 1, further comprising a housing to house the elastic member and the damping element.

5. The protractible component as claimed in claim 1, wherein the body portion is to extend from the mounting member about a bumper edge to an angle of about 160°

to 180°

in a protracted position.

6. A device comprising:

a frame;

a protractible component comprising;

a body portion comprising a hinging edge having a mounting member at each end of the hinging edge, each mounting member having an arcuate profile formed thereon; and

a hinge set coupled between each mounting member and the frame to achieve protractibility of the protractible component, each hinge set comprising;

a support hinge comprising a first end and a second end, wherein the first end of the support hinge is pivotably mounted at a fixed position on the frame and the second end of the support hinge is pivotably coupled at a fixed position on the mounting member of the body portion;

a guide hinge comprising a first end and a second end, wherein the first end of the guide hinge comprises a follower to cooperate with the arcuate profile of the mounting member to guide the mounting member, and the second end of the guide hinge is pivotably coupled at a fixed position on the frame;

an elastic member to couple the body portion to the hinge set, wherein the elastic member is to protract the protractible component; and

a damping element to couple the body portion to the hinge set, wherein the damping element is to control protraction by the elastic member.

7. The device as claimed in claim 6, wherein the arcuate profile is formed as a groove in the mounting member.

8. The device as claimed in claim 6, wherein the body portion comprises a locking edge having a latching member to detachably latch the body portion to the frame when the protractible component is retracted.

9. The device as claimed in claim 6, wherein the protractible component is one of a tray for a reproduction device, a screen, and a cover.

10. The device as claimed in claim 6, wherein the protractible component is to open from the mounting member about a bumper edge to an angle of about 160°

to 180°

in a protracted position.

11. A hinge set for a protractible component of a device, the hinge set comprising:

a first mounting bracket to couple the hinge set to the protractible component;

a second mounting bracket to couple the hinge set to the device for mounting the protractible component on the device;

a support hinge comprising a first end and a second end, wherein the first end of the support hinge is pivotably coupled to the first mounting bracket and the second end of the support hinge is pivotably coupled to the second mounting bracket;

a guide hinge comprising a first end and a second end, wherein the first end of the guide hinge cooperates with the first mounting bracket to guide the first mounting bracket, and the second end of the guide hinge is pivotably coupled to the second mounting bracket;

an elastic member to protract the protractible component; and

a damping element to control protraction by the elastic member, wherein the elastic member and the damping element are coupled between the first mounting bracket and the second mounting bracket.

12. The hinge set as claimed in claim 11, wherein the first mounting bracket comprises a groove having an arcuate shape, the first end of the guide hinge comprising a follower to cooperate with the groove.
