Abstract

Disclosed herein are hinge devices having reduced or minimized free play. Specifically, disclosed herein are hinge devices having surface elements positioned on a surface of a hinge component to reduce or eliminate any free play present between interacting hinge components. In one or more embodiments, the hinge includes a first hinge component having a first guide and a second hinge component having a second guide, wherein the second hinge component is rotatably mounted on at least one surface of the first hinge component such that the first guide is positioned within the second guide or the second guide is positioned within the first guide. At least one surface element is disposed on a surface of the first guide or the second guide to provide a reduction in free play at a location of the at least one surface element.

Claims

1. A hinge comprising:

a hinge frame configured to be connected to a chassis of an electronic device;

a cam configured to be connected to a support component of the electronic device, wherein the cam is in communication with the hinge frame;

a cam follower configured for interaction with the cam during a user manipulation of the support component;

a telescoping link having a first end and a second end, the first end being pivotally connected to the cam follower;

an anchor link having a first end and a second end, the first end being pivotally connected to the hinge frame and the second end having an opening; and

at least one support plate,

wherein the hinge frame comprises a hinge guide,

wherein the at least one support plate comprises a first support plate guide positioned on a first surface and a second support plate guide positioned on a second surface of the at least one support plate, the second surface being an opposite surface of the first surface, wherein the at least one support plate is rotatably mounted on a surface of the hinge frame such that the first support plate guide is positioned within the hinge guide or the hinge guide is positioned within the first support plate guide, defining a first interaction,

wherein the cam comprises a cam guide, wherein the cam is rotatably mounted on a surface of the at least one support plate such that the cam guide is positioned within the second support plate guide or the second support plate guide is positioned within the cam guide, defining a second interaction,

wherein the second end of the telescoping link is positioned within the opening of the anchor link and is configured to slide within the opening between the first end and the second end of the anchor link as the cam moves between a plurality of positions relative to the hinge frame, and

wherein a surface element is disposed on a surface of the telescoping link or a surface of the anchor link to provide a reduction in free play at a location of the surface element as the telescoping link slides within the opening.

2. The hinge of claim 1, wherein the surface element is at least one raised bump or a thermoplastic polymer composition molded over at least a portion of the surface of the telescoping link or at least a portion of the surface of the anchor link.

3. The hinge of claim 1,

wherein an additional surface element is disposed on a surface of the hinge guide, the first support plate guide, the second support plate guide, or the cam guide to provide a reduction in free play at a location of the additional surface element of the first interaction or the second interaction.

4. The hinge of claim 3, wherein the additional surface element comprises a first surface element disposed on the hinge guide or the first support plate guide, and a second surface element disposed on the second support plate guide or the cam guide.

5. The hinge of claim 3, wherein the additional surface element is disposed on the hinge guide or the first support plate guide such that the hinge guide abuts the first support plate guide at the surface element throughout a rotation of the at least one support plate about the hinge plate.

6. The hinge of claim 3, wherein the additional surface element is disposed on the second support plate guide or the cam guide such that the second support plate guide abuts the cam guide at the surface element throughout a rotation of the cam about the at least one support plate.

7. The hinge of claim 1, wherein the reduction in free play is a form fit at the location of the surface element.

8. The hinge of claim 1, wherein the reduction in free play is an interference fit at the location of the surface element.

9. The hinge of claim 1, wherein the surface element is at least one raised bump, wherein each bump is in a shape of a half-sphere.

10. The hinge of claim 9, wherein the at least one raised bump is a same material as the surface of the telescoping link or the surface of the anchor link to which the at least one raised bump is attached.

11. The hinge of claim 9, wherein the at least one raised bump is a polymer composition adhered to the surface of the telescoping link or the surface of the anchor link.

12. The hinge of claim 1, wherein the surface element comprises a thermoplastic polymer composition molded over at least a portion of the surface of the telescoping link or at least a portion of the surface of the anchor link.

13. The hinge of claim 1, wherein the surface element provides a coefficient of friction of 0.2 or less when the surface element interacts with an opposing guide surface.

14. The hinge of claim 1, wherein the surface element comprises a metal coating composition having a Mohs hardness of 4 or less.

15. An electronic device comprising:

a chassis;

a support component; and

a hinge configured to pivotally connect the support component with the chassis, the hinge being positionable in a plurality of positions relative to the chassis, the hinge comprising;

a hinge frame connected to the chassis, the hinge frame having a hinge guide;

at least one support plate having a first support plate guide positioned on a first surface and a second support plate guide positioned on a second surface of the at least one support plate, the second surface being an opposite surface of the first surface, wherein the at least one support plate is rotatably mounted on a surface of the hinge frame such that the first support plate guide is positioned within the hinge guide or the hinge guide is positioned within the first support plate guide, defining a first interaction; and

a cam connected to the support component, the cam having a cam guide, wherein the cam is rotatably mounted on a surface of the at least one support plate such that the cam guide is positioned within the second support plate guide or the second support plate guide is positioned within the cam guide, defining a second interaction,

a cam follower configured for interaction with the cam during a user manipulation of the support component;

a telescoping link having a first end and a second end, the first end being pivotally connected to the cam follower; and

an anchor link having a first end and a second end, the first end being pivotally connected to the hinge frame and the second end having an opening,

wherein the second end of the telescoping link is positioned within the opening of the anchor link and is configured to slide within the opening between the first end and the second end of the anchor link as the cam moves between a plurality of positions relative to the hinge frame, and

wherein a surface element is disposed on a surface of one or more of the hinge guide, the first support plate guide, the second support plate guide, or the cam guide to provide a reduction in free play at a location of the surface element of the first interaction or the second interaction.

16. The electronic device of claim 15,

wherein an additional surface element is disposed on a surface of the telescoping link or a surface of the anchor link to provide a reduction in free play at a location of the additional surface element as the telescoping link slides within the opening.

17. The electronic device of claim 16, wherein the reduction in free play is a form fit at the location of the surface element.
