Abstract

A hinged system includes a preassembled hinge module for pivotally coupling a first component to a second component. The preassembled hinge module includes a shaft, a torque element frictionally engaging the shaft, and a housing. The housing includes a cover, a side wall, and a rear wall that define an interior space enclosed within the housing. The interior space receives the torque element inside the housing. The cover defines a first aperture, and the rear wall defines a second aperture, the first aperture and the second aperture aligned with a pivot axis of the shaft. The shaft extends through at least the first aperture, the interior space, and the second aperture. The shaft is separate from, and configured to be mounted to, the first component. The housing is separate from, and configured to be mounted to, the second component.

First claim

What is claimed:

1. A preassembled hinge module configured for coupling a first component to a second component for pivotal movement relative to one another, the preassembled hinge module comprising:
a shaft defining a pivot axis;
a torque element frictionally engaging the shaft, the torque element having a perimeter defining a recess; and
a housing having a side wall, a rear wall, and a cover, the side wall and the rear wall and the cover together defining an interior space within the housing, wherein the interior space is configured to receive the torque element inside the housing, wherein the side wall of the housing comprises a rounded detent or protrusion extending into the interior space within the housing, the detent or protrusion being configured to secure the torque element inside the housing and limit rotation of the torque element relative to the housing;
wherein the cover defines a first aperture and the rear wall defines a second aperture, the first aperture and the second aperture being aligned with the pivot axis of the shaft, with the shaft extending through at least the first aperture, the interior space of the housing, and the second aperture;
wherein the shaft is separate from, and configured to be mounted to, the first component; and
wherein the housing is separate from, and configured to be mounted to, the second component.

2. The preassembled hinge module of claim 1 , wherein the detent or protrusion extends into the recess defined in the perimeter of the torque element, thereby limiting movement of the torque element relative to the housing.

3. The preassembled hinge module of claim 1 , wherein the detent or protrusion extends into a recess defined in the cover, thereby limiting movement of the cover relative to the housing.

4. The preassembled hinge module of claim 1 , wherein the rear wall of the housing defines a groove, the groove defined in the rear wall of the housing and the torque element together defining a receptacle configured to receive a lubricant.

5. The preassembled hinge module of claim 4 , wherein the interior space forms a reservoir that contains the lubricant.

6. The preassembled hinge module of claim 4 , wherein the lubricant includes grease.

7. The preassembled hinge module of claim 4 , the groove having a transverse portion oriented to extend in a direction transverse relative to the pivot axis of the shaft.

8. The preassembled hinge module of claim 4 , the groove having a radial portion oriented to extend in a direction radial relative to the pivot axis.

9. The preassembled hinge module of claim 1 , wherein the rear wall of the housing defines a passageway, the passageway defined in the rear wall of the housing being configured to receive a lubricant.

10. The preassembled hinge module of claim 9 , wherein the rear wall of the housing further defines a groove, the groove defined in the rear wall of the housing being in communication with the passageway defined in the rear wall of the housing for flow of the lubricant into the passageway and into the groove.

11. The preassembled hinge module of claim 1 , wherein the rear wall of the housing comprises a universal mounting surface configured to be mounted to the second component.

12. The preassembled hinge module of claim 1 , wherein the torque element defines an aperture aligned with the pivot axis of the shaft, with the shaft extending through the aperture in frictional engagement with the torque element.

13. The preassembled hinge module of claim 1 , wherein the side wall has an inner surface, supplemental to the detent or protrusion, configured to secure the torque element inside the housing and prevent the torque element from rotation with respect to the housing.

14. The preassembled hinge module of claim 1 , wherein the side wall has an inner surface, supplemental to the detent or protrusion, also configured to secure the torque element inside the housing and prevent the torque element from rotation relative to the housing, and the inner surface defines one or more ridges for securing the torque element.

15. The preassembled hinge module of claim 1 , wherein the rear wall extends beyond the side wall to form an extension.

16. The preassembled hinge module of claim 15 , wherein the extension of the rear wall defines a third aperture for receiving a mounting fastener to mount the housing to the second component.

17. The preassembled hinge module of claim 1 , wherein the rear wall and the side wall of the housing are integrally formed as a single body of unitary construction that is separate from the cover.

18. The preassembled hinge module of claim 1 , comprising plural torque elements frictionally engaging the shaft.

19. The preassembled hinge module of claim 1 , wherein the interior space receives the torque element in a form-locking fit.

20. The preassembled hinge module of claim 1 , wherein at least a portion of a perimeter edge of the cover is engaged with a surface of an upper portion of the side wall that extends inwardly and over the portion of the perimeter edge of the cover, thereby securing the cover in place.

21. A preassembled hinge module system configured for coupling a first component to a second component for pivotal movement relative to one another, the preassembled hinge module comprising:
a shaft defining a pivot axis, the shaft being separate from, and configured to be mounted to, the first component;
a torque element frictionally engaging the shaft;
a housing containing the torque element, the housing having a side wall and a cover, and wherein at least a portion of a perimeter edge of the cover is engaged with a surface of an upper portion of the side wall that extends inwardly and over the portion of the perimeter edge of the cover, thereby securing the cover in place; and
an adapter having an end configured for fixed coupling to the shaft and an opposite end configured for releasable coupling to the first component.

22. The preassembled hinge module system according to claim 21 , wherein the shaft is mated to the adapter, the adapter defining a counterbore opening to receive a portion of an end of the shaft.

23. The preassembled hinge module system of claim 21 , wherein when the at least a portion of the perimeter edge of the cover is engaged with the surface of the upper portion of the side wall, the surface of the upper portion of the side wall and the at least a portion of the perimeter edge of the cover is in a fluid tight crimped connection.

24. The preassembled hinge module system of claim 21 , wherein an entirety of the perimeter edge of the cover is engaged with the surface of the upper portion of the side wall.

25. The preassembled hinge module system of claim 21 , wherein the surface of the upper portion of the side wall is deformable in at least one of a downward and inward direction, thereby engaging the at least a portion of the perimeter edge of the cover.

26. The preassembled hinge module system of claim 21 , wherein when the at least a portion of the perimeter edge of the cover is engaged with the surface of the upper portion of the side wall, the cover provides a partial or full seal against ingress of contaminants into an interior space of the housing.

27. The preassembled hinge module system of claim 21 , wherein when the at least a portion of the perimeter edge of the cover is engaged with the surface of the upper portion of the side wall,
