DETAILED DESCRIPTION OF EMBODIMENTS

Attention is directed to the annexed drawings, showing in Fig. 1A a 2x2 cabinet generally designated 10 comprising (apart for its non-referenced side walls, top base, bottom base, back, shelves, etc.) a top right door 12, a bottom right door 14, a top left door 16 and a bottom left door 18. It is appreciated that in the given example components of the cabinet disclosed may be made of injection molded plastic material.

The four doors 12, 14, 16 and 18 are in fact the same molded element, i.e. one form of molded panel 22 (Figs. IB and 1C) can be used as any of the four doors. As seen in these Figures, the panel 22 at the orientation of Fig. IB serves as a right-rail hinged door configuration (namely suitable as top door 12 and/or bottom door 14 in the cabinet 10 of Fig. 1A), whilst rotating the panel 22 upside-down, as in Fig. 1C, renders it suitable for use as a left-rail hinged door configuration (namely suitable as top door 16 and/or bottom door 18 in the cabinet 10 of Fig. 1 A).

It is seen in Figs. IB and 1C that the panel 22 is configured at its respective bottom/top rail with a first cavity 24 and a second cavity 26, each configured for snapingly receiving therein a door reinforcing element 30 (seen in detail in Fig. 2). Each such door reinforcing element 30 extends within the respective opening of the top/bottom rail of the panel 22, between respective hinge stile edge 34 to the respective locking stile 36, thus rigidifying/stiffening the panel board 22.

As will be clarified herein after with reference to Figs. 4A-4D, there is a designated right side door reinforcing element 30 member and a left side member door reinforcing element. Each door reinforcing element 30 comprises a flat top surface 40, which at the assembled position extends flush with a respective top/bottom edge of the door panel (best seen in Figs. 3A-3C).

Door reinforcing element 30 further comprises a handle portion 42 configured such that at the assembled position it extends near an inside edge of the door (i.e. near the locking stile 36 and remote from the hinge stile 34), and a plurality of support ribs 44 and flanges 46 configured for reinforcing the panel edge and stabilized positioning of the door reinforcing element 30 within the cavity at the open rail end of the door panel (24; 26), whereby lateral projections 47 serve for snapingly engaging with openings 49 at the panel 22, for arresting the door reinforcing element 30 within the cavity (24; 26) at the panel's respective rail. Handle portion 42 is configured with a recessed groove 48 having a flat base surface 50, extending towards an opening 52 and configured at that location with an indention 54, for snapingly arresting a locking member (80 in Figs. 5A- 5B) as will be discussed hereinafter.

At the event that the handle portion 42 is left free, i.e. without inserting a locking member 80 (as will be discussed below), neighboring doors at a side-by-side configuration (such as doors 62 and 64 of cabinet 66 in Fig. 6) can be locked to one another at their closed position, with a padlock 68 (single shackle or U-shaped shackle) extending through the opening 52 of the neighboring respective door reinforcing element 30A and 30B (as seen in Fig. 3F). In Fig. 3F there is an enlarged view of the center handle portion of the cabinet 10, wherein the four neighboring door reinforcing elements 30A and 30B are seen, however without a locking member 80 introduced. Thus, each of the four doors 12, 14, 16 and 18 is independently pivotable between its closed and open position; further, each pair of side-by-side doors, i.e. top doors 12 and 16, and bottom doors 14 and 18, can be locked to one another by introducing a pad lock (schematically represented by dashed lines 68, applied over the bottom doors only) through the respective vacant openings 52A and 52B, now serving as locking eyes, thereby locking the respective doors and preventing unauthorized opening thereof.

Figs. 5A and 5B illustrate a locking member 80 according to an example of the disclosure, the locking member 80 generally has an L-shape and comprises a first leg portion 84 and a second leg portion 94. The first leg portion 84 has two opposite flat sliding surfaces 86 sized and shaped for snugly receiving and sliding over the flat base surface 50 within recessed groove 48 of the door reinforcing element 30. An end of the respective sliding surfaces 86 is provided with chamfered snap protrusion 88, configured for snapingly arresting by indentions 54 at the door reinforcing element 30. Furthermore, the locking member 80 is provided with a support and locking projection 90, configured for snugly arresting within opening 52 of the respective door reinforcing element 30. The second leg portion 94 is configured with a locking eye 96 and can optionally serve as a gripping handle.

The arrangement is such that the locking member 80 is applied first to a door reinforcing element 30B bottom door panel (e.g. bottom left door 18) within recessed groove 48 and is slidingly displaced over the flat base surface 50 towards the locking stile end, whereupon the protrusion 88 snapingly arrests by indention 54 at the door reinforcing element 30B with simultaneous arresting of the locking projection 90 within opening 52 of the respective door reinforcing element 30B, whereby the locking member 80 is now fixed to a bottom door panel 18 of a pair of doors (18 and 16). Then, the top door (16 respectively) is manipulated and slightly twisted (owing to resiliency of the door panel) such that the locking member 80 snaps into position within the door reinforcing element 30A of the top left door panel 16, similar to the arrangement discussed hereinbefore regarding door reinforcing element 30B, whereby the two doors 16 and 18 become integrated (Figs. 3G, 3J, 4A, 4C), i.e. are affixed to one another such that displacing one of the doors entails corresponding, simultaneous displacement of the attached door.

The same arrangement is then applied to the right pair of doors, namely bottom right door panel 14 and top right door panel 12, wherein a locking member 80 is applied and interlocked between said doors, (Figs. 31 and 3J), whereupon the two doors 14 and 12 integrate and will simultaneously displace. Further, a single pad lock can now be applied (schematically represented by dashed lines 68) for locking of all four door panels (12, 14, 16 and 18).

For sake of clarity, in Fig. 4B there is illustrated a pair of door reinforcing elements 30A and 30B integrated to one another by a respective locking member 80 interlocked therebetween, as explained herein, wherein the two door reinforcing elements 30A and 30B (with their associated doors; not shown) become united one with the other. In Fig. 4D there are illustrated two pairs of door reinforcing elements 30A and 30B integrated to one another by a respective locking member 80 interlocked therebetween, as explained herein, wherein each of the left set of doors and right set of doors (doors not shown) become united with one another respectively.

It is appreciated that the locking members 80 can be readily removed, at any time, at a reverse sequence of mounting to that described hereinabove.

It is noted, that at the integrated position of the doors, the respective flat surface 40 of the top door reinforcing elements 30A and 30B are in close proximity and can extend flush over one another.

Further realized, applying the two locking members to the doors of a 2x2 cabinet in fact convert it into lockable, two doors at a side-by-side door configuration. Also, the integration of doors to one another through a locking member can take place in larger scale, for example, a 2x6 door cabinet can be manipulated so that three left side doors and/or three right side doors are integrated to one another (not shown), thereby resulting in a united side-by-side door configuration, wherein a top rail of a bottom left door panel is secured to a bottom rail of a middle left door, and further a top rail of the middle left door is secured to a bottom rail of the top left door panel.

Further attention is directed to Fig. 7, illustrating a top door 100 over a bottom door 102, of a cabinet (not shown), wherein at a neighboring portion of the two doors there is applied a locking member 106 snapingly fastened at 108 and 110 to the two doors 100 and 102, respectively, thereby uniting the two doors, such that they now act in an integrated fashion. Similar to the previous example, the locking member 96 is configured with a locking eye 114 for locking with a neighboring locking eye (not shown). It is appreciated that whilst the locking member 106 is fastened to the respective doors 100, 102 at a handle portion 116, 118, respectively, other locations can be configured, however at the respective top rail 120 and bottom rail 122 of the doors, and near the locking stile thereof. The handle portion of the door panels can be integral with or assembled thereto.

It is also appreciated that snap-type fastening as disclosed herein before is an example and other arrangements can be facilitated as well, such as a threaded coupling, wedge-coupling, etc.

The disclosed arrangement is such that at door-over-door orientation the locking member can be removed upon displacing the door panels into an at least partially open position. Accordingly, at the closed position of the doors the locking member articulating the two doors cannot be manipulated/removed.
