1. Cabinet Tower
Referring to FIG. 1, a cabinet system 110 includes three towers 112, 114, 116 (e.g., supply towers, cabinets) coupled together in a first configuration 110A. Each tower 112, 114, 116 includes four doors 118, which may be right hinged or left hinged. Each door 118 has a manual lock 120. In other embodiments, the towers may include other numbers of doors. In some embodiments, the doors 118 may not include locks, or may include electric locks (e.g., solenoid latch). The towers 112, 114, 116 may be fastened to each other in any order—for example, in FIG. 2 the towers 112, 114, 116 are coupled together in a different configuration 110B.
The tower 114 (e.g., user access center tower) includes a user interface 122 (e.g., user access center, controller, computer monitor and keyboard, etc.). A user may control features of the cabinet system 110 (e.g., locks, lighting, etc.) or catalog inventory of the cabinet system 110 via a processor (see, e.g., processor 2060 as shown in FIG. 61) coupled to the user interface 122. In other embodiments, features of the cabinet system 110 may be controlled, cataloged, etc., by an external computer or network of computers. In still other embodiments, the cabinet system 110 does not include a controller.
Referring to FIGS. 3-4, a cabinet system 210 includes two towers 212, 214. Each of the towers 212, 214 includes doors 216 having locks 218. The tower 214 includes a user interface 220 having a monitor 222, an extendable keyboard 224, and printer output slots 226. A door 216 above the user interface 220 includes an extension 228 coupled to the bottom thereof. The cabinet system 210 additionally includes a stability bracket 230 (see also FIGS. 15-16) configured to increase the support base of the cabinet system 210, increasing stability. In some embodiments, the cabinet system 210 includes slots for gripping the cabinet system 210 to move the cabinet system 210. An indicator 232 may provide information to an operator, such as whether a particular door 216 is locked. Indicator 232 may be, for example, a light-emitting diode configured to visually indicate (e.g. turn on, flash, blink, pulse, etc.) the status of the door. In one embodiment, an indicator 232 may be configured to turn fully on when a door in unlocked, flash or blink when a door is unlocked and to further indicate the location of a supply item, and turn off when the door is opened or when the door is locked.
Referring now to FIGS. 5-6, 10, cabinet systems 310, 410, 510 each include components similar to those discussed with regard to cabinet systems 110, 210. Cabinet systems 410,510 do not include a user interface. FIGS. 7-9 show the cabinet system 410 from different view points. Referring specifically to FIG. 8, a stability bracket 412 extends the support base of the cabinet system 410. FIGS. 11-13 show the cabinet system 510 from different view points, where casters 512 are shown in FIG. 12 below the cabinet system 510.
Referring now to FIG. 14, a cabinet system 610 includes a first tower 612 having four doors 616, and a second tower 614 in a partially-assembled configuration. In some embodiments, the doors 616 are transparent or translucent, while in other exemplary embodiments, the doors 616 are generally opaque. Doors 616 may be wholly transparent or translucent, e.g. formed from a sheet of transparent or translucent material such as glass or plastic, or may be partially transparent or translucent, e.g. contain a transparent or translucent window within a door frame. A key 620 is removably inserted into a key hole 622 of the first tower 612. In some embodiments, all key holes (of one or more than one tower) share a common key. The first and second towers 612, 614 are configured to be fastened together, or to operate separate from each other. The second tower 614 includes a user interface 618. Additionally, a power cord 624 is coupled to the first tower 612.
II. Support Bracket
Referring to FIGS. 15-16, a cabinet tower 710 includes a support bracket 712 (e.g., extension, stability bracket, etc.). FIG. 15 shows the support bracket 712 in an operational configuration, while FIG. 16 shows the support bracket 712 partially disassembled from the cabinet tower 710. The support bracket 712 may include fastening structures 714 (e.g., bolt holes), and is configured to withstand a large weight without deformation (e.g., a moment greater than 1000 ft-lbf; greater than 2000 ft-lbf). As mentioned, the support bracket 712 is configured to extend the support base of the cabinet tower 710 by moving further forward the point about which the cabinet tower 710 would rotate upon tilting or tipping forward.
III. Hinge Assembly
Referring to FIGS. 17-20, a first hinge assembly 810 (FIG. 17) and a second hinge assembly 910 (FIGS. 18-19) each include a pin (e.g., pivot) and fasteners 812, 912 (e.g., threaded fasteners) coupling a door 814, 914 (fastened to first bracket 816, 916) to a cabinet tower 818,918 (fastened to a second bracket 820, 920). The second hinge assembly 910 is preferred over the first hinge assembly 810 because the portion of the door 914 to which the hinge assembly 910 is fastened includes a cut-out portion 922 thereof. The cut-out portion 922 allows for easier coupling and decoupling of the door 914 from the second hinge assembly 910, when compared to the first hinge assembly 810. According to an exemplary embodiment, a user need only remove (e.g., unscrew) the fasteners 912 to remove the door 914 from the hinge assembly 910.
FIG. 19 shows the hinge assembly 910 from outside of the door 914, and FIG. 20 shows a hinge assembly 1010 of a design similar to the second hinge assembly 910 of FIGS. 18-19, but with only one door 1012 attached thereto. Each door 814, 914, 1012 may be coupled to two or more hinge assemblies 810, 910, 1010 (e.g., on top and bottom thereof).
Referring now to FIG. 21, a cabinet system 1110 includes two doors 1112, 1114. The two doors 1112, 1114 are fastened together by a coupling kit 1116. The coupling kit 1116 includes a bracket 1118 (e.g., T-shaped bracket) fastened to the bottom of the top door 1112 and to the top of the bottom door 1114. When the doors 1112, 1114 are fastened together with the coupling kit 1116, the two doors 1112, 1114 function as a single door, such as a door to a large compartment. Where two doors (or more) are joined by a T-shaped bracket 1118 to provide access to a large compartment, duplicate access control features (e.g., second electronic lock, second manual lock) may be removed or disengaged such that access to the large compartment is controlled by a single operation. Additionally, operation of a duplicate indicator feature 232 (as shown in FIGS. 3-4) may be disabled to indicate to a user that the doors 1112, 1114 are operable as a single door.
IV. Lighting
Referring to FIGS. 22-27, a lighting feature 1212 of a cabinet tower 1210 includes an array of light-emitting diodes 1214 positioned within walls 1216 of the cabinet tower 1210, behind transparent or translucent panels 1218. In some embodiments, the lighting feature 1212 is activated when doors 1220 of the cabinet tower 1210 open, and is deactivated when the doors 1220 close (e.g., by way of a manual switch, optical switch, potentiometer, etc.). In some embodiments, the lighting feature 1212 may be manually activated or deactivated by a light switch (see, e.g., switch 1318 as shown in FIG. 29).
Where lighting feature 1212 includes light-emitting diodes 1214, illumination levels may be variably operated by pulse-width modulation of the power input to the light-emitting diodes 1214, to output any illumination level between zero brightness and full brightness. Illumination levels may be selectively applied to individual compartments, or uniformly to all compartments of a cabinet. In one embodiment, lighting feature 1212 is activated in at a first brightness (such as full brightness), when a door is opened, and activated at a second brightness (such as 50 percent of full brightness, 25 percent of full brightness, zero percent of full brightness) when a door is closed. In other embodiments, activation of lighting feature 1212 (preferably in a compartment having a transparent or translucent door) may be used to provide information to an operator, such as whether a particular door 216 has been placed in an unlocked condition. Lighting feature 1212 may be modulated (e.g. on-off flashing, bright-dim pulsing) to provide visual information to an operator. Lighting features 1212 of cabinet 1210 may also be placed in a second brightness mode after a period of inactivity or during defined times of day.
In other embodiments, traditional light bulbs or other lighting elements are used. FIG. 22 shows an upper portion of the cabinet tower 1210, and FIG. 23 shows a lower portion of the cabinet tower 1210.
