Abstract

A collapsible cabinet frame articulates between a collapsed form and an expanded form. The collapsible cabinet form includes a first side frame with front corner posts, rear corner posts, and a plurality of front to back beams extending between the front corner post and the rear corner post. A second side frame with front corner posts, rear corner posts, and a plurality of front to back beams extending between the front corner post and the rear corner post. A front upper side to side beam and a front lower side to side beam are hingedly connected to the first side frame and the second side frame. A rear upper side to side beam and a rear lower side to side beam are hingedly connected the first side frame and the second side frame.

First claim

1 . A collapsible cabinet frame for articulating between a collapsed form and an expanded form, the collapsible cabinet frame comprising:
a first side frame and a second side frame, the first side frame and second side frame each include a front corner post, a rear corner post, and a plurality of front to back beams extending between the front corner post and the rear corner post; a front upper side to side beam and a front lower side to side beam hingedly connected to the first side frame and the second side frame: and a rear upper side to side beam and a rear lower side to side beam hingedly connected to the first side frame and the second side frame.

2 . The collapsible cabinet frame of claim 1 , wherein the plurality of front to back beams includes an upper front to back beam, a middle front to back beam, and a lower front to back beam.

3 . The collapsible cabinet frame of claim 2 , wherein the upper front to back beams have a top flange with hinge pin guide holes and a bottom flange with hinge pin guide holes; and
the lower front to back beams have a top flange with hinge pin guide holes and a bottom flange with hinge pin guide holes.

4 . The collapsible cabinet frame of claim 3 , wherein the front upper side to side beam and the rear upper side to side beam are positioned between the top flange and the bottom flange of the upper front to back beams of the first side frame and the second side frame; and the front lower side to side beam and the rear lower side to side beam are positioned between the top flange and the bottom flange of the lower front to back beams of the first side frame and the second side frame.

5 . The collapsible cabinet frame of claim 4 , wherein the front upper side to side beam and the front lower side to side beam include hinge pin guide holes; the rear upper side to side beam and the rear lower side to side beam include hinge pin guide holes.

6 . The collapsible cabinet frame of claim 5 , wherein the hinge pin guide holes in the upper front to back beams align with the hinge pin guide holes in the upper front side to side beam and the upper rear side to side beam; and
wherein the hinge pin guide holes in the lower front to back beams align with the hinge pin guide holes in the lower front side to side beam and the lower rear side to side beam; whereby the aligned hinge pin guide holes receive hinge pins to hingedly connect the collapsible cabinet frame.

7 . The collapsible cabinet frame of claim 3 , wherein casters are mounted to the bottom flange of the lower front to back beams.

8 . The collapsible cabinet frame of claim 3 , wherein the top flange of each upper front to back beam includes locking pin holes; the bottom flange of each lower front to back beam includes locking pin holes; and the side to side beams include locking pin holes at each end, whereby when the cabinet is expanded the locking pin holes of the side to side beams align with the locking pin holes of the upper front to back beams and the lower front to back beams for receiving a fastener to lock the expanded frame.

9 . The collapsible cabinet frame of claim 1 , wherein the front corner post, the rear corner post and the front to back beams are welded together to form the first side frame and the front corner post, the rear corner post and the front to back beams are welded together to form the second side frame.

10 . The collapsible cabinet frame of claim 1 , wherein the front upper side to side beam and the front lower side to side beam are positioned between the first side frame and the second side frame; and the rear upper side to side beam and the rear lower side to side beam are positioned between the first side frame and the second side frame.

11 . The collapsible cabinet frame of claim 1 , wherein the frame further comprising a door positioned between the first side frame and the second side frame; at least one equipment rail secured to one of the front to back beams; and a top cap.

12 . The collapsible cabinet frame of claim 11 , wherein the door, equipment rails and top cap are positioned inside the cabinet frame while in the collapsed form for shipping.

13 . The collapsible cabinet frame of claim 1 , wherein the frame is rotated from a collapsible form to an expanded form.
