Abstract

A hinge can be used between two structures to allow the structures to be quickly and easily folded and unfolded. The hinge has a first body connected to a structure and a second body connected to a structure. The first and second bodies are also connected to one another by a sliding member that allows the hinge to be extended and folded.

Claims

1. A hinge comprising:

a first body having a post, the first body configured to be attached to a first structure and having a neck portion;

a second body configured to be attached to a second structure;

a sliding member having a slot formed therein, the sliding member slidably attached to the first body and pivotally connected to the second body; and

a collar connected to the second body and configured to selectively engage the neck portion such that when the collar is engaged with the neck portion the hinge is in a locked position and the second body cannot be rotated with respect to the first body; and

wherein the collar has an interior rim and when the collar is engaged with the neck portion, the interior rim contacts a stud of the second body to hold the second body in position with respect to the first body; and

wherein the slot has a detent to selectively hold the post within a portion of the slot.

2. The hinge of claim 1 wherein the post is a fastener for securing the first body to the first structure.

3. The hinge of claim 1 wherein when the collar is rotated in a first direction, the collar disengages the neck portion such the hinge is in the unlocked position and when the collar is rotated a second direction, the collar engages the neck portion such that the hinge is in a locked position.

4. The hinge of claim 3 wherein the collar is rotated between about 30 and 60 degrees to move the hinge between the locked position and unlocked position.

5. The hinge of claim 3 wherein the collar has an opening formed therein sufficient to allow the second structure to extend through the opening to slidably attach the collar to the second structure.

6. The hinge of claim 1 wherein the stud is a fastener for securing the second body to the second structure.

7. A hinge comprising:

a first body configured to be attached to a first structure and having a neck portion;

a second body configured to be attached to a second structure;

a sliding member slidably attached to the first body and pivotally connected to the second body; and

a collar connected to the second body and configured to selectively engage the neck portion such that when the collar is engaged with the neck portion the hinge is in a locked position and the second body cannot be rotated with respect to the first body; and

wherein the collar has an interior rim and when the collar is engaged with the neck portion, the interior rim contacts a stud of the second body to hold the second body in position with respect to the first body; and

wherein the sliding member is rotatably attached to a bar at one end of the bar and the bar is rotatably attached to the second body at a second end of the bar.

8. The hinge of claim 7 wherein the sliding member has a first recess formed therein and the second body has a second recess formed therein and the bar is partially located in the first recess and second recess.

9. The hinge of claim 7 wherein the bar is rotatably connected to a post portion of the second body and the post portion includes an angled surface such that when the second body is rotated with respect to the first body, the second body does not contact the neck portion.

10. A hinge for pivotally connecting a first structure to a second structure,

the hinge comprising:

a sleeve body configured to be attached to the first structure;

a base body having at least one tab and configured to be attached to the second structure;

a post slidably received by the base body and rotatably attached to the sleeve body;

a boom rotatably attached to the post at a first end of the boom and rotatably attached to the sleeve body at a second end of the boom; and

a sleeve configured to selectively engage the at least one tab such that when the sleeve is engaged with the at least one tab the post cannot be slid and when the sleeve is not engaged with the at least one tab, the post can be slid such that a portion of the post extends out of the base body.

11. The hinge of claim 10 wherein when the sleeve is not engaged with the at least one tab and the portion of the post extends out of the base body, the sleeve can be rotated with respect to the base body.

12. The hinge of claim 11, wherein the sleeve can be rotated to be generally parallel to the base body.

13. The hinge of claim 12 wherein the sleeve has at least one groove that is configured to receive the at least one tab.

14. The hinge of claim 13 wherein the at least one groove includes a bump to selectively hold the at least one tab within a portion of the at least one groove.

15. The hinge of claim 10 wherein the post is slidably received in an opening formed in the base body, the opening having at least one straight side and wherein the post has at least one flat portion configured to cooperate with the straight side of the opening to slide into and out of the base body.

16. The hinge of claim 15 wherein the opening has opposing straight sides;

wherein the post has opposing flat portions that cooperate with the opposing straight sides; and

wherein a distance between the flat portions increases from a front end of the post such that when the portion of the post is sufficiently extended out of the base body, the flat portions will contact the flat sides to selectively wedge the post in the opening.

17. A collapsible accessory comprising:

a frame having at least a first structure and a second structure; and

a hinge located between and attached to the first structure and second structure, the hinge further comprising;

a first body having a neck portion;

a post having a slot;

a first fastener extending through the first body, first structure and slot to attach the first body to the first structure and slidably attach the post to the first body;

a second body having a post portion and attached to the second structure by a second fastener,

a collar with an opening forming an interior surface and an interior rim,

a boom rotatably connected at a first end to the post and at a second end to the second body;

wherein the second structure extends through the opening to attach the collar to the second structure to allow the collar to move along the second structure,

wherein the movement of the collar is limited in a first bearing when the interior rim contacts the second fastener;

wherein the interior surface has a plurality of grooves;

wherein each groove of the plurality of grooves is generally L-shaped;

wherein the neck portion has a plurality of tabs that correspond to the plurality of grooves;

wherein the collar be slid in the first bearing such that the plurality of tabs are received in the plurality of grooves;

wherein when the plurality of tabs are received in the plurality of grooves, the collar can be rotated to engage the hinge and prevent the collapsible accessory from collapsing;

wherein when the plurality of tabs are not received in the plurality of grooves, the post can slide at least partially out of the first body and the collapsible accessory can collapse.
