DETAILED DESCRIPTION
Embodiments described in this application can provide a memory button mount that is simple, compact, durable, and effective in providing electrically readable IDs for security objects, such as keys. Memory buttons can be attached to tags connected to keys to give each key or group of keys an ID. The tags cooperate with respective pockets or cages attached to a support surface to mount the memory buttons to which they are connected. The pockets can bias the memory buttons toward the support surface to engage contacts so that each memory button can be read electrically. In addition, the pockets can facilitate removal and replacement of memory buttons, as well as keys connected thereto via the tags.
With reference to FIGS. 1-5, a mount 100 can include a tag 200 which can be inserted into a pocket or cage 300 attached to a support 10, which can include a support surface 12 (FIGS. 3-5). Tag 200 can include main body 210 that can hold a memory button 220. A key flange 230 can project from main body 210 and can include a ring passage 232 through which a key ring 20 or the like can pass to attach at least one key 30 to tag 200 or vice versa. A label flange 240 can also extend from main body 210 and can be used to bear indicia 242 or the like to identify tag 100 and/or associated keys attached thereto or vice versa.
As can be seen, tag 200 can be inserted into pocket or cage 300, with main body 210 sliding against an inner surface of a main wall 310 of pocket or cage 300 and key flange 230 sliding in a slot 312 of main wall 310 of pocket or cage 300. Slot 312 in embodiments can include rounded entry corners 314 to aid insertion of tag 200 into pocket or cage 300, and can include an end 316 that can stop key flange 230 at a desired point. Pocket or cage 300 can include opposed sidewalls 320 which can each bear at least one leg 322. Each leg 322 can include a knee 324 to hold sidewall 320 off of the support surface 12 (FIGS. 3-5). In embodiments, pocket or cage 300 can also include an end wall 330, which can also include at least one leg 332, which can each include a respective knee 334. Where end wall 330 is included, it can strengthen the connection between pocket or cage 300 and the support structure 10, though in embodiments the end wall 330 can be omitted.
While tag 200 and pocket or cage 300 can be made from any suitable material and/or by any suitable method, embodiments include forming tag 200 and/or pocket or cage 300 from sheet metal. With reference to FIGS. 6-9, tag 200 can be formed from a flat 202, which can be formed from sheet metal or the like. Flat 202 can include a central main body portion 212 with a hole 214 therein through which memory button 220 can be inserted. Here button 220 is left out so that it does not obstruct the view of tag 200, but it should be understood that memory button 220 should be inserted through hole 214 before bending flat 202 to form tag 200. FIGS. 10-13 show tag 200 formed and with memory button 220 inserted therein. In particular, a rim 226 of memory button 226 can be engaged by portions of flat 202 and/or tag 200 to facilitate electrical communication with memory button 220.
As can particularly be seen in FIG. 6, flat 202 can include left and right main wall portions 216,218, as well as left and right key flange portions 234, 236. Each key flange portion 234, 236 can include a respective key passage hole 237, 238. Inner fold lines 211, 213 and outer fold lines 215, 217 are included in FIG. 6 for illustrative purposes, but it should be understood that these are not necessarily marked on flat 202. In embodiments, however, material along fold lines 211, 213, 215, 217 can be removed and/or thinned and/or perforated and/or otherwise weakened to reduce force required to bend the relevant portions of flat 202, as well as to reduce formation of sharp corners and/or edges during bending.
Referring again to FIGS. 6-9, left and right main wall portions 216, 218 can be folded in a first direction around inner fold lines 211, 213 toward central main body portion 212, with left and right key flange portions 234, 236 folded in a second, opposite direction around outer fold lines 215, 217 away from central main body portion 212. Left and right main wall portions 216, 218 can thereby press against memory button 220 (not shown in FIGS. 6-9) to retain it in hole 214. In addition, with left and right key flange portions 234, 236 aligned and/or in engagement, key passage holes 237, 238 can form key passage 232. Further, a grommet or the like can be inserted into key passage 232 to urge and retain key flange portions 234, 236 together, as well as to facilitate insertion of a key ring through key passage 232.
Like tag 200, pocket or cage 300 of embodiments can be formed from a flat 302, as seen in FIGS. 14-17. Flat 302 can include main wall 310 as a central portion thereof, with opposed sidewalls 320 included as left and right portions of flat 302. Where included, end wall 330 can be included as a bottom portion of flat 302. Flat 302 can include any or all features of pocket or cage 300, which can include slot 312, rounded entry corners 314, end 316 of slot 312, legs 322, 332, and/or knees 324, 334. Fold lines 311, 313, 315 are shown in FIG. 14, but are not necessarily marked on flat 302. In embodiments, as with tag 200, material along any or all of fold lines 311, 313, 315 can be removed and/or thinned and/or perforated and/or otherwise weakened to reduce bending force required and/or bulk of material in pocket or cage 300 when formed. Opposed sidewalls 320 can be folded in a first direction around fold lines 311, 313 until substantially perpendicular to main wall 310, and, where included, end wall 330 can be bent around fold line 315 until substantially perpendicular to main wall 310.
In embodiments, memory button mount 100 can be part of a security asset management system (SAM) in which support structure 10 can include a circuit board or the like. For example, as seen in FIG. 18, a SAM 40 can include a controller 270 coupled to a user interface 272 and a database 274 including user information and associated authentication information. Controller 270 can also be coupled to an asset panel 276 of support structure 10 via a 1-wire communication bus 278. The 1-wire communication bus refers to the fact that only one signal wire is needed (in addition to a ground connection) for communication. A suitable 1-wire communication bus may be implemented using the Dallas Semiconductor 1-wire protocol developed for their touch memory iButton devices and is familiar to those skilled in the art. Such touch memory iButton devices can be used as memory button 220 of embodiments of tag 200 and mount 100 described above.
A connector 280 can be provided on asset panel 276 to have a 1-wire signal connection 282 and a ground connection 284. A plurality of memory button mounts, here pockets or cages 300, can be present on asset panel 276, each pocket or cage 300 being mounted in electrical communication with a first electrical contact 288 on support surface 12 of panel 276 and over a second electrical contact 290 on support surface 12 of panel 276. Second electrical contacts 290 can be located so that, referring again to FIGS. 3-5 in conjunction with FIG. 18, when a tag 200 is inserted into a pocket or cage 300, a respective contact surface 222 of a respective memory button 220 can be in electrical communication with a respective second electrical contact 290. Second electrical contacts 290 can be coupled to 1-wire signal connection(s) 282 by circuit traces and/or other conductive paths, such as, but not limited to wires. Similarly, first electrical contacts 288 can all be coupled to ground connection 284 by circuit traces and/or other conductive paths, such as, but not limited to wires, and pockets or cages 300 can be in electrical communication therewith. For example, sidewalls 320 and/or legs 322 can be connected to first contacts 288, though other arrangements fall well within the scope of embodiments of the invention disclosed herein.
Using a 1-wire protocol, controller 270 can query the asset panel 276 coupled to 1-wire bus 278 to see what, if any, memory button identification tags 200 are plugged into pockets or cages 300. If a memory button 220 is present, it will respond to a query from controller 270, letting the controller know the memory button (and therefore the asset associated with the memory button) is present. Depending on the embodiment, a greater or fewer number of pockets or cages 300 can be present on a given asset panel 276, and more than one asset panel 276 could be coupled to 1-wire communication bus 278 at the same time.
In embodiments, pocket or cage 300 and tag 200 can be sized so that insertion of tag 200 into pocket or cage 300 results in a snug fit or even a slight interference fit to ensure that contact surface 222 of memory button 220 has sufficient electrical contact with contact 290. In addition, main wall 310 of pocket or cage 300 can be bent in such a way as to exert a spring force on tag 200 when tag 200 is inserted, urging substantially planar contact surface 222 against support surface 12 and/or contact 290.
The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
