Abstract

An assembly according to some embodiments of the disclosure includes an enclosure having a housing and door hingedly attached to the housing and a door stop mechanism which holds the door in an open position. The mechanism includes a link member pivotally connected to the door and to the housing. The link member has an elongated slot which extends along a portion of the link member. The slot has a linear portion and an enlarged opening at an end thereof which is offset from the linear portion. When the door is opened, a fastener, which is either mounted to the housing or to the door, slides along the slot until the fastener is positioned in the enlarged opening to hold the door open.

Claims

1. An assembly comprising:

an enclosure comprising a housing and door hingedly attached to the housing, a cavity formed within the housing, the door being configured to be moved into an open position to expose the cavity and configured to be moved into a closed position to close the cavity;

a door stop mechanism configured to hold the door in the open position relative to the housing, the door stop mechanism comprising;

a link member pivotally connected to the door and to the housing, the link member having first and second opposite ends, opposite first and second faces and a centerline defined between the opposite ends, the link member being linear and planar,

a first fastener fixedly attached to one of the link member and the door and being rotatably attached to the other of the link member and the door, the first fastener being proximate to, but spaced from, the first end of the link member;

an elongated slot provided through the link member from the first face to the second face, the slot having first and second ends, the slot extending along a portion of the length of the link member, the first end of the slot being spaced from the first end of the link member, the second end of the slot being proximate to, but spaced from, the second end of the link member, the slot comprising a linear portion which extends along a portion of the length of the link member and an enlarged opening at an end of the linear portion, the enlarged opening being offset from the linear portion but in communication with the linear portion, the enlarged opening being proximate to, but spaced from, the second end of the link member and the first fastener; and

a second fastener fixedly attached to the housing, the second fastener mounted in the slot and slideable within the slot and configured to be positioned within the linear portion when the door is in the closed position and configured to be positioned within the enlarged opening when the door is in the open position, the link member being rotatable around the second fastener.

2. The assembly of claim 1, wherein the link member comprises first and second walls which are offset from each other by an intermediate wall, wherein the slot is provided through the second wall.

3. The assembly of claim 2, wherein the first wall has opposite first and second faces and opposite ends, wherein a length and a centerline of the first wall is defined between the opposite ends, the first wall extending from the first end of the link member, and the second wall having opposite first and second faces and opposite ends, wherein a length and a centerline of the second wall is defined between the opposite ends of the second wall, the second wall extending from the second end of the link member, the intermediate wall connecting the first wall to the second wall such that the centerlines of the first and second walls are offset from each other.

4. The assembly of claim 3, wherein the centerlines of the first and second walls are parallel to each other.

5. The assembly of claim 3, wherein the intermediate wall is angled from the first wall to the second wall.

6. The assembly of claim 3, wherein each of the first and second fasteners comprises a shaft having an enlarged head at an end thereof, the enlarged head of the first fastener being engaged against the first wall and the enlarged head of the second fastener being engaged against the second wall.

7. The assembly of claim 1, wherein the first end of the slot comprises an angled surface and the enlarged opening comprises an angled surface extending from the angled surface of the slot.

8. The assembly of claim 7, wherein the enlarged opening further comprises a linear surface extending at an angle relative to the angled surface of the enlarged opening and a rounded surface which extends from the linear surface.

9. The assembly of claim 1, wherein the housing comprises a rear wall, a first side wall extending forwardly from the rear wall, a second side wall extending forwardly from the rear wall, a top wall extending forwardly from the rear wall and joining the upper ends of the rear wall and side walls together, a bottom wall extending forwardly from the rear wall and joining the lower ends of the rear wall and side walls together, and wherein the second fastener is attached to the bottom wall of the housing.

10. The assembly of claim 1, wherein the enclosure is a job storage box.

11. The assembly of claim 10, wherein the job storage box is formed of metal.

12. The assembly of claim 1, wherein each of the first and second fasteners comprises a shaft having an enlarged head at an end thereof, the enlarged head of the first fastener being engaged against the link member and the enlarged head of the second fastener being engaged against the link member.

13. The assembly of claim 12, wherein the first and second fasteners are screws.

14. The assembly of claim 1, wherein the first and second fasteners are screws.

15. The assembly of claim 1, further comprising a first washer mounted between the link member and the housing, and a second washer mounted between the link member and the door.

16. The assembly of claim 1, wherein the link member is formed of metal.

17. The assembly of claim 1, wherein the first fastener is fixedly attached to the door and extends through an aperture in the first wall.

18. The assembly of claim 1, wherein the first end of the slot is at a midpoint of the link member.
