Figures 1 and 2 show a secure enclosure 100 for a tablet display device 102 forming an embodiment of the invention. The secure enclosure 100 comprises a tablet display device holder 104 which is formed from a case 106 and a faceplate 108. The case 106 and faceplate 108 define thcrchctwccn a cavity for receiving the tablet display device 102 within the holder 104. The faceplate 108 is held securely to the case 106 by means of a latch mechanism (described in greater detail below) which is operated by a lock 124. A faceplate through-hole 110 within the faceplate 108 allows access to a screen 112 of the tablet display device 102.
The secure enclosure 100 further comprises a stand 114 which is attached at its upper end 116 to the device holder 104 at the case 106. The stand 114 comprises a neck ring body 117 at the upper end 116 of the sLnd 114. a stalk 118. a stalk base 120 distal to the neck ring body 117 and a stalk base cover 122.
Figure 3 is a partially exploded sectional side view of the secure enclosure 100. In this view, the faceplate 108 has been separated from the case.
Figure 4 is a rear view of the case 106 of the device holder 104. The case 106 has a central aperture 126. Around the aperture 126 there is a case fixing ring 128 for mounting the case 106 on the upper end 116 ol the stand 114. As can he seen in Figure 3, the case fixing ring 128 is recessed within an outer shell of the ease 106.
The case fixing ring 128 has a number of through-holes. namely four case fixing through-holes 130 interspersed between four case location through-holes 132. The case location through-holes 132 are used to position the case 106 on the upper end 116 of the stand 114 which has case location pins 136 as shown in Figure 5. The case location pins 136 are inserted into the case location through-holes 132 of the case 106.
To secure the case 106 to the upper end 116 of the stand 114, case fixing bolts (not shown) are inserted through the case fixing through-holes 130 and screwed into the upper end 116 of the stand 114.
With reference to Figure 6, a flange 142 is formed at a bottom end 144 of the stalk base 120. Apertures 146 in the flange 142 receive lixing screws 148 br attaching the stand 114 to a surface, such as a counter, wall or table. Alternatively, bolts, screws or other fixing means may be used to attach the stand 114 to a surface from beneath the stand 114.
Figure 7 is a view of the inside of the case 106. The case 106 includes a vanity panel which is shown in Figure 8. The vanity panel 150 covers most of the moving parts of the case 106. Figure 9 is the same view as Figure 7 but with the vanity panel removed. Figures IDA and lOB are views of a lock huh 152 forming part of the case 106 and Figure 11 is a perspective view of one of six latch mechanisms 154 deployed around a perimeter of the case 106.
A locking arrangement comprises the lock 124. a lock cam 156. the lock hub 152. six latch cables 158 and the six latch mechanisms 154. The lock 124 is connected by a shaft (not shown) to the latch cam 156.
With reference to Figures IDA and lOB, the lock huh 152 is annular, having a central aperture 182. The outer edge 192 of the lock hub 152 is comprised of six arcs 193 which follow a circumference of a circle. Between each pair of arcs 193 the outer edge 192 follow a partial chord 195 after which it curves around in the shape of a hook 194, such that there are six hooks 194 around the penphery of the lock hub 152 between the six arcs 193. The inner edge 197 of the lock huh 152 comprises seven ares 199 which follow a circumference of a first circle, six arcs 201 which follow a S circumference of a second circle of greater diameter than thc first circle and a notch 153 which extends from the central aperture 182 into the body of the lock hub 152 to accommodate the lock cam 1 56.
With reference to Figure 9, in the assembled enclosure 100, the lock hub 152 is disposed in a generally annular channel 186 defined in the case by an inner wall 188 and outer wall sections 190 which extend from the shell of the case 106 into the cavity of the case 106. The inner wall 188 and the outer wall sections 190 can be seen in the detailed views of Figure 3 and in Figure 9. The outer wall 190 and the inner wall sections 188 of the annular channel 186 include arcs which follow a circumference of respective circles of diameters similar to the diameters of the respective arcs 193, 199 of the outer 192 and inner 197 edges of the lock huh 152, such that the lock huh 152 is arranged to have limited rotation within the annular channel 186.
Each of the six latch cables 158 is attached to a hook 194 around the periphery of the lock hub 152. Each latch cable 158 runs from the lock hub 152 around a respective latch cable diverter 160 to its respective latch mechanism 154.
Each latch mechanism 154 comprises a latch housing 162 having a bore (not shown) in which a latch 164 is slidably mounted. An end of the latch 164 protrudes from the bore into a latch cavity 168. A latch return spring 166 (see Figure 9) is disposed between the latch housing 162 and the latch 164 to bias the latch 164 into the latch cavity 168.
The end face 170 of the latch 164 is inclined. Each latch 164 is connected by its respective latch cable 158 to the lock hub 152. Figure 11 also shows a tablet support insert 184 which is disposed proximal to the latch housing 162.
Figure 12 is a rear view of the faceplate 108 and Figure 13 is a side view thereof.
There are six striker heads 172 protruding from a body 174 of the faceplate 108. A rubber compression foot 179 protrudes from a surface 178 of each striker head 1 72 which is distal to the faceplate body 174. The striker head 172 without the compression foot 179 is shown in greater detail in Figures 14A to l4C. From these figures it can been seen that there is a cavity 196 open to an end 198 of the striker head 172 distal to the compression foot 179. The cavity 196 is defined partially by an overhanging wall 200 forming pail of the upper surface 178 of the striker head 172.
Figure 15 is a sectional view of the enclosure 100. In this view it can be seen that when the faceplate 108 is mounted on the case 106 the rubber compression foot 179 abuts a compression point 180 on the case 106. Furthermore, it can been seen that when the latch return spring 166 is frilly extended, the latch 164 is fully extended from the latch housing 162 and engages with the overhanging wall 200 of the striker head 172 to prevent separation of the faceplate 108 from the case 106. This Figure also shows how the faceplate 108 is curved around to meet the case 106. This features provides a security benefit by making levering the faceplate 108 off the case 106 more difficult than if the body 174 of the faceplate 108 was flat and also means that any spillages onto the faceplate 108 are more likely to flow onto the rear of the case 106, rather than to seep inside the enclosure 100. In addition, by moving the split line, where the faceplate 108 meets the case 106. backwards it is less likely that fingers will come in contact with the split line, so that if a user has wet or dirty hands when touching the enclosure 100 the water or dirt will not come in contact with the split line.
In operation, when the enclosure 100 is unlocked the faceplate 108 can be removed from the case 106 as follows. With reference to Figure 9 when the lock 124 is rotated the lock cam 156 is in turn rotated clockwise, as shown in this Figure. The lock cam 156 abuts a wall of the lock hub notch 153 and urges the lock hub 152 to rotate clockwise. The clockwise rotation of the lock hub 152 causes each of the latch cables 158 to move away from its respective lock housing 162. This causes compression of the latch return springs 166 and withdraws the latches 164 from engagement with the striker head overhanging wall 200. Once the latch 164 is fully reiracted from the striker head overhanging wall 200 the faceplate 108 may be removed from the case 106 and the tablet display device 102 may be removed from or placed into the case 106.
To secure the faceplate 108 to the case 106, the lock is returned to its original position.
This moves the lock cam 156 away from the lock hub 152, allowing the latch return springs 166 move the atches 164 into the latch cavity 168 and rotating the lock huh 152 anti-clockwise in Figure 9. The faceplate 108 is positioned over the ease 106.
When the faceplate 108 is pushed towards the case 106 the upper surface 178 of the striker heads 172 ride along the inclined surface 170 of the latches 164. to push the latches 164 into the bores of the atch housing 162. Once the faceplate 108 and the case 106 are pressed together sufficiently for the striker heads 172 to pass beyond the latches 164, the latch return springs 166 urge the latches 164 away from the latch housings 162 so that the rear of the latch 164 engages with the overhanging wall 200 oithe striker head 172.
Since the six latch mechanisms 154 are located around the periphery of the enclosure 100. this provides multiple locking points to securely attach the faceplate 108 to the ease 106 and enhances the security of the enclosure 100. In addition, by depthying multiple latches the security of the enclosure 100 is enhanced, since it would be necessary for each of the latches to be broken during an attempted theft.
With reference to Figures 2 and 3. the secure enclosure 100 includes two rotation mechathsms which allows the enclosure 100 to rotate around a vertical first axis X-X at. its base 120 and around a second axis Y-Y. which is inclined to the vertical and which is orthogonal to the device holder 104. Figure 16 shows the secure enclosure oriented in different positions about the axis X-X. The rotation mechanisms described below provide the secure enclosure 100 with limited rotation about these axes. Regarding rotation about axis X-X, the rotation is limited so that the case does not extend beyond a broken line 202 shown in Figure 16. For example, if the secure enclosure 100 is mounted against a wall represented by the line 202, the case 106 will not strike against the wall, thereby preventing damage to both the case 106 and the wall. It will be understood that the rotation mechanism can be configured to provide rotation about the axis X-X of other amounts, such as 180° and 270°, which are provided as non-limiting examples only.
With reference to Figure 3, the stalk 118 is able to rotate about the axis X-X of the annular stalk base 120 and the rotation mechanism is described below. The stalk base is shown in greater detail in Figures 17A to 17D. The stalk base 120 can be divided vertically into five sections as shown in Figure 17B. The upper section of the stalk base 120 is a foot 208, which protrudes beyond a surface 232 of the tubular second section 120a of the stalk base 120. With reference to Figure 17D, the foot 208 follows an arc above the tubular second section 120a and subtends an angle of around degrees between its vertical end faces 222. The end faces 222 are concave such that their shape conforms to thc outer surfacc of the rotation stopper pin 218.
The diameter of the tubular portion 120a corresponds to the inner diameter of a shouldered hearing sleeve 210, shown in Figure 3. The outer diameter of the sleeve 210 corresponds to the inner diameter of the stalk 118. The thickness of the wall of the stalk 118 is set such that the extemal surface of the stalk 118 is flush with the middle section 12Db of the stalk base 120 shown in Figure 17B.
The lowest portion of the stalk base 120 is the flange 142 described above, which is used to attach the stand 114 to a surface. The portion 120c of the stalk base 120 between the flange 142 and the middle section 120b has a diameter which is greater than the diameter of the middle section 12Db and less than the diameter of the flange 142. As shown in Figure 3, the stalk base covcr 122 is thc same height as the combined height of the flange 142 and the section 120c of the stalk base 120 such that when the stalk base cover 122 is placed over the stalk base 120 the flange 142 and the lower portion 120c are concealed by the stalk base cover 122. Furthermore, since the tubular portion l2Oa of the stalk base 120 is disposed within the stalk 118 and the sleeve 210, the only exposed portion of the stalk base 120 is the middle section 12Db.
The stalk base 120 is attached by a through hole bolt 204 to a through bolt mount ring 206. The through hole bolt 204 is a hollow bolt which allows a power/data cable for the tablet display device 102 to be fed therethrough. The through hole bolt 204 has a bolt head 224 at a first end 226 and a threaded external portion 228 at an end 230 distal to the bolt head 224.
The through bolt mount ring 206 is shown in greater detail in Figures 18A to 18D.
Like the through hole bolt 204, the through bolt mount ring 206 is hollow so that a power cable can pass therethough. As can be seen in Figure 18C, the upper portion 206a of the through bolt mount ring 206 is chamfered to assist guidance of a power cable into the through bolt mount ring 206. The lower portion 206b of the through bolt mount mg 206 has a constant inner diameter and is threaded so that the threaded external portion 228 of the through hole bolt 204 can be screwed into the lower portion 206h of the through boll mount ring 206.
In the assembled stand 114, a plurality of friction washers 140 arc disposed between the head 204 of the through hole bolt 204 and the stalk base 120. The function of the friction washers 140 is to provide variable tension in the rotatable connection between the through bolt mount ring 206 and the stalk base 120. During the assembly of the stand 114 the through hole bolt 204 is screwed into the through bolt mount ring 206 until the correct tension is set to allow for rotation between the stalk base 120 and the stalk 118. The friction washers 140 also prevent loosening of the threaded connection between the threaded external portion 228 of the through hole bolt 204 and the through bolt mount ring 206.
As can he seen from Figures ISA to ISC, the through bolt mount ring 206 has four cylindrical cavities 216. As shown in Figure 3, a rotation stopper pin 218 is inserted into one or more of these cavities 216. The length of the rotation stopper pin 218 is greater than the depth of the cavities 216 such that the rotation stopper pin 218 partially extends above the surface 220 of the through bolt mount ring 206. The height of the portion of the rotation stopper pin 218 which extends above the suitace 220 of tile through bolt mount ring 206 is set such that in the assembled stand 114 the end of the rotation stopper pin 218 is spaced from the surface 232 of tubular second section 120a of the stalk base 120 and engages with the end faces 222 of the foot 208.
Consequently, and to assist with understanding the structure of the rotation mechanism. in the assembled stand 114 there is a cavity 234 between the surface 232 of tubular second section 120a of the stalk base 120 and the surface 220 of the through bolt mount ring 206, as shown in Figure 3. In the assembled stand 114 there is also an annular cavity 235 between the through hole bolt 204 and the stalk base 120.
The engagement of the rotation stopper pin 218 with the end faces 222 of the foot 208, which act as first and second abutment faces, defines the extent to which the stalk 118 is able to rotate about the axis X-X shown in Figure 3. By deploying more than one rotation stopper pin 218 in the cavities 216 of the through bolt mounting ring 206, the extent to which the stalk 118 is able to rotate about the axis X-X can be varied, as required. Similarly, the extent to which the foot 208 subtends around the upper surface 232 of the tubular second section 1 20a of the stalk base 120 can he varied to achieve the same purpose.
With reference to Figure 3, the device holder 104 is able to rotate about the axis Y-Y with respect to the stalk 118 as a result ol the rotation mechanism at the top of the stalk 118 which is described below.
The neck ring body 117 is shown in detail in Figures 19A to 19E. The neck ring body 117 has an end portion 244 which is inserted into and fixed to a hollow upper end portion 242 of the stalk 118. As can be seen in Figure 19C. the neck ring body 117 has a through bore 256. A portion 264 of the bore 256 in the end portion which is inserted into the upper end portion 242 of the stalk 118 is threaded. The end portion 244 of the neck ring body 117 which is inserted into the stalk 118 has a chamfered mouth 246 to assist guidance of a power cable through the bore 256 neck ring body 117. A second portion 248 of the neck ring body 117 which is distal to the first portion 244 has a shallow cylindrical cavity 250. At the foot of the cylindrical cavity 250 there is a shoulder 252 which extends around the bore 256 of the neck ring body 117. Within the shoulder are a pair of cylindrical cavities 254 for receiving a rotation stopper pin 218, as shown in Figure 3.
A switch body 236 is shown in Figures 20A to 20E. The shallow cylindrical cavity 250 of the neck mg body 117 receives a cylindrical boss 258 of the switch body 236.
Figure 5 shows the switch body 236 when it is inserted into the neck ring body 117 at theupperend 116 of the stand 114.
As can he seen in Figure 20A and in Figure 5. the switch body 236 has a central bore 266 and around its periphery four case fixing through holes 238 interposed between four case location cavities 240. As shown in Figure 5, a case location pin 136 is inserted into each of the case location cavities 240 so as to align the switch body 236 with the case 106, by inserting the case location pins 136 into the corresponding case location through holes 132 of the case 106.
With reference to Figure 20D, the switch body 236 has a cylindrical cavity 260 which is open to a first side 262 of the switch body 236. The switch body 236 is attached to the neck ring body 117 by inserting a through hole bolt 204 (the bolt head 224 of which is shown in Figure 5) through the cylindrical cavity 260 and the bore 266 and subsequently screwing the threaded portion 228 of (he through hole bolt 204 into (he threaded portion 264 of the bore 256 of the neck ring body 117. When the through hole bolt 204 is attached to the neck ring body 117 the bolt head 224 is disposed within the cylindrical cavity 260. As with the attachment of the through hole bolt 204 to the through bolt mount ring 206 at the stalk base 120, a plurality of friction washers 140 are disposed between the bolt head 224 of the through hole bolt 204 and the switch body 236.
With reference to Figures 20C and 20E, the cylindrical boss 258 has an arcuate cut-out 270 open to a second side 278 of the switch body 236. The arcuate cut-out is open along its inner diameter to the bore 266 of the switch body 236 and has two end faces 272 at its ends. As with the end faces 222 of the stalk base 120, the end faces 272 of the arcuate cut-out 270 are concave such that their shape conforms to the outer surface of the rotation stopper pin 218.
Refening now to Figure 3. a rotation stopper pin 218 is inserted into one of the cylindrical cavities 254 of the neck ring body 117. When the switch body 236 is attached by the through hole bolt 204 to the neck nng body 117, the portion of the rotation stopper pin 218 which protrudes from the neck ring body 117 into the shallow cylindrical cavity 250 is disposed within the arcuate cut-out 270. As the switch body 236 (and the device holder 104, which is attached to the switch body 236) rotates about die axis Y-Y relative to the neck ring body 117, the rotation stopper pin 218 moves along the arcuate cut-out 270. The end faces 272 of the arcuate cut-out 270 define the extent to which the switch body 236 and the device holder 104 are able to rotate relative to the stand 114 and act as first and second abutment faces for the rotation stopper pin 218, thereby providing limited relative rotation of the neck ring body 117 and the switch body 236. The extent to which rotation about the axis Y-Y is possible is typically set such that the device holder 104 can rotate between a vertical (portrait) position and a horizontal (landscape) position.
To assist with understanding the structure of the upper rotation mechanism, in the assembled stand 114 there is a cavity 274 between the wall of the cylindrical cavity 260 and the surface 220 of the through bolt mount ring 206, as shown in Figure 3. In the assembled stand 114 there is also an annular cavity 276 between lie through hole bolt 204 and the stalk neck ring body 117.
Various modifications will be appareni to those in the art and it is desired to include all such modifications as fall within the scope of the accompanying claims.
For example, the secure enclosure 100 described above has six latch mechanisms 154 around the periphery of the case 106. In other embodiments the enclosure may have more or less than six of these latch mechanisms 154. For example the secure enclosure may have only two latch mechanisms, or may have 3, 4, 5, 7, 8 or any other number of latch mechanisms around the periphery of the case 106 and faceplate 108.
In the secure enclosure 100 described above the case central aperture 126 through which the display device power cable is fed is disposed within the central aperture 182 of the lock hub 152 and the annular channel 186 of the case 106, such that the lock hub 152 rotates around the central aperture 126. In other embodiments the lock hub 152 may not rotate about the aperture through which the power cable is fed.
In the secure enclosure 100 described above, the rotation stopper pins 218 are inserted into the neck ring body 117 and the through bolt mount ring 206 and the abutment laces 222, 272 are on the stalk base 120 and the switch body 236. In other embodiments one or both of the rotation stopper pins 218 may be inserted into the stalk base 120 and the switch body 236 and the abutment faces may he on the through bolt mount ring 206 and the neck ring body 117.
In the secure enclosure 100 described above, rotation is limited by abutment of the rotation stopper pin 218 with abutments faces 222, 272. The skilled person will understand that the rotation stopper need not be a cylindrical pin and that other rotation stoppers may he used to abut the abutment faces.. Such rotation stopper protrusions may be integrally formed on their carrying part or, like the rotation stopper pins 218. may be inserted into a cavity of their carrying part (this arrangement providing an easier manufacturing process).
In the secure enclosure 100 described above, the compression foot 179 is described as being made of rubber. In other embodiments springs may be used in place of rubber compression feet. An advantage of using springs is that these springs would push the faceplate 108 away from the case 106 when the enclosure 100 in unlocked.
Alternatively, the function of the rubber compression foot 179 may be integrated into a tablet support insert.
