DETAILED DESCRIPTION

(15) In FIGS. 1 to 3, a framework in the form of a sanitization booth 10 has side walls 12 approximately twice as long as it's entrance and exit openings 14, 16 are wide to permit a person to step into the booth and pass therethrough while being sprayed or misted with a sanitization or disinfection liquid, from above 18, below 20, and the sides 22 by liquid sanitizer pumped through a reticulation pipe system 24 and through nozzles 26 along the extent thereof, thereby to sanitize the person, their clothing, as well as their footwear including the soles thereof.

(16) The booth 10 includes a hand sanitization portion 28 at the entrance 14 to the booth 10 so that the person who has been sanitized by passing through the booth also sanitizes their hands which have been used to cover their eyes while in the booth.

(17) The booth 10 has side walls 30, 32 made from stainless sheeting and a grated floor 34 whereby the mist or spray directed at the person from below 20 passes through the floor to wet the soles of the footwear of the person, while also permitting drainage of the booth.

(18) The booth also includes a roof or ceiling 36 also made from the same sheeting so that the booth 10 has two open ends, the entrance and exit openings 14, 16 for the person to enter and exit the booth while preventing the spray or mist from being distributed laterally and upwardly out of the booth.

(19) An upper zone 38 of the liquid reticulation system 24 extends substantially around the periphery of an upper portion of the booth 10, in 0 or rectangular-fashion, so that the spray or mist is directed at the person in the booth from above as well as angularly from above to improve coverage by the liquid. Likewise, the lower zone 40 of the liquid reticulation system 24 extends transversely the floor 34 of the booth 10.

(20) In FIG. 4, in an embodiment of the invention, a booth 50 (detection & sanitization station) has a steel frame 52 passageway, with open ends 54, 56 for person/s to step into, walk through and exit on the opposite end. The booth 50 has a floor 58 which comprises of non-slip grating seated in a steel drip tray/catchment area 60. The frame 52 has sheeting 62 all round except for the entrance 54 and exit 56. On the right is a sub-frame 64 to support a 220V electric motor and pump system 66 with a liquid container 68 (header tank) mounted in flow communication and higher than an inlet of the pump 66.

(21) The pump 66 is connected to and feeds a piping reticulation system 69 which distributes sanitization liquid solution from the container 68 to mist sprayers 70 which are distributed along the piping 69 above, along the sides and from below to achieve a 360 degree coverage and distribution of the liquid over the person/s inside the booth.

(22) An infra-red camera 72 is mounted on the entrance 54 of the booth and is connected to a set of green, amber and red indication lights (not shown) and wired to a control box mounted on the frame (not shown).

(23) A motion sensor 74 is mounted on the ceiling of the frame 52 to detect when a person/s have entered the booth.

(24) A flow meter (not shown) will be mounted to the pump 66 to record volume dispensed for control of efficacy of the booth.

(25) The booth has 5 lockable wheels 76 mounted on the corners of the base 78 and one supporting the sub frame 80.

(26) Thus, in use, a person/s will stand at the entrance of the detection & sanitization station booth and during scanning or standby the amber indication light will be illuminated. Once scanned, if the temperature detected is higher than the upper pre-set limit, the red indication light will be illuminated as an alarm and the person/s will be asked to step aside for further examination. If cleared, the green indication light will illuminate allowing the person/s to enter for sanitization at entrance 54. The motion of the person entering the booth will trigger the motion sensor 74 mounted on the ceiling of the station which will toggle the electric motor to ON, driving the pump 66 which will begin distributing the sanitization liquid solution for a pre-set time period to adequately sanitize the person/s inside the unit, once the run cycle is complete the motor will automatically switch off and the person/s can leave the station.

(27) In order to ensure that there is no manipulation of the quality of the sanitizer or disinfectant, the container 68 is sealed and locked and the key kept by a responsible person to reduce the risk of tampering.

(28) The outflow from the container 68 will be monitored through a flow meter to ensure that the sanitizer or disinfectant is correctly fed to the pump 66. The pump may be a dosing type pump. This is good for quality assurance as only the approved pre-mixed sanitizer or disinfectant will be utilized and records are kept and verified between the flow meter and the quantities supplied by the supplier. This will then allow for effective analysis of the amount of sanitizer or disinfectant used per person who went through the booth.

(29) In another example shown in FIG. 5, the apparatus 100, for example for home use, is in the form of a framework 102 shaped and dimensioned similarly to a doorway 104 opening with which it is operatively associated so that a person passing through the doorway may be sanitized. The apparatus 100 includes nozzles 106 located to spray the footwear of the person including soles thereof.

(30) The apparatus 100 is configured to have nozzles 106 located at 5 locations over the extent of liquid reticulation tubing 108 built into the framework 102 so that they spray inwardly onto the person passing through the apparatus 100 from above, the sides, and from below thereby to mist the person almost entirely or entirely.

(31) This example includes a spray nozzle 110 for spraying a parcel or the hands of a person passing through the apparatus 100.

(32) In use, the control box 112 mounted on frame 102 has a start button 114 which is pushed for 10 seconds for person full-body spray or 2 seconds for parcel spray operations.

(33) In the example shown in FIG. 6, the home or office use apparatus 120 of the invention is a self supporting archway in the form of a free standing tubular frame 122 on which a reticulation system 124 is mounted with 8 nozzles for spraying or misting into the archway from the top, bottom and sides. A 25 liter sanitizing fluid tank 130 with a sight glass and sanitizing fluid pumping system 126 provides the pressurized sanitizing fluid for so that the fluid may sprayed from above, laterally, and below the soles of footwear of a person passing therethrough. The pump has an enclosure 132 and an isolation switch 134. The entire enclosure 132 is removable for ease of assembly and disassembly of the apparatus 120.

(34) The apparatus 120 includes a motion sensor 128 and an IR camera 131 for automated operation and symptom detection.

(35) FIG. 7 shows an apparatus similar to that of FIG. 6, but converted to make a booth 200 having collapsible and detachable cladded panels 202 attached to a tubular frame 204 as well as piping 206 and 10 nozzles 208 typically holds the IR monitor and camera. As shown for FIG. 6, the nozzles are arranged for spraying or misting into the archway from the top, bottom (soles of shoes) and sides. A 25 liter sanitizing fluid tank 230 with a sight glass and sanitizing fluid pumping system 226 provides the pressurized sanitizing fluid so that the fluid may sprayed from above, laterally, and below the soles of footwear of a person passing therethrough. The pump has an enclosure 232 and an isolation switch 234. The entire enclosure 232 is removable for ease of assembly and disassembly of the booth 200.

(36) In FIG. 8 the detail of the enhanced reticulation system of the booth of FIG. 7 over that of the apparatus of FIG. 6 is shown. The reticulation system 206 includes 10 nozzles for spraying or misting into the booth from the top, bottom and sides as well as an additional overhead piping and nozzles ring main and a bottom section 208 including spray nozzles for the soles of shoes.

(37) FIG. 9 is a high-volume booth similar to that of FIGS. 1 to 4 but designed for higher traffic of persons to be sanitized. This booth 300 is automated and intelligent with a built in 2000 liter tank 302 for long running capacity. The booth 300 is clad with cladding 303, has a motion detector and IR temperature scanner 304 to determine whether a person will be allowed to enter the booth and, if permitted to enter, to initialize sanitization. The user will see indication lights 306 which are green and red.

(38) The booth 300 has a tubular frame 308 and a reticulation system 310 of piping with 16 nozzles for misting from all directions inside the booth 300. The person to be sanitized stands on the grating 312 inside the booth 300 and excess liquid from the misting runs into a drip tray 314 and then out of a drip point 316.

(39) The booth 300 is provided with a pump 318 for the sanitizing liquid from tank 302 and an access ramp 322 into the booth. The booth 300 stands on wheels 320 for easy relocation.

(40) An isolation panel and controls 324 with a programmable controller complete the package.

(41) FIGS. 10 to 12 show an example of a kit 400 for assembly of a booth 410 such as that shown in FIGS. 1 to 4, wherein 120 mm length 32 mm32 mm square tubing 402 is used as a shaft 404 which gets welded onto the 38 mm38 mm square tubing 406 that makes up the framework 412. A sleeve 408 is made of 38 mm38 mm square tubing 406 to connect sections of the 32 mm32 mm shaft 404 to corresponding shafts 404 thereby to assemble the framework 412 of the booth 410. This thus forms a joint as the sleeve 408 slides over the shaft 404 and locks into position using bolts passing through the holes (not shown) and tightening the nuts so that the nuts and bolts are the securing means.

(42) All the shafts 404 and the sleeves 408 have two holes 414 that are pre-drilled that are in register and line up perfectly when the shaft 404 and sleeve 408 are assembled. Once assembled, the booth framework 412 stands firm without the bolts being inserted and nuts tightened.

(43) As can be seen in FIG. 10, the shaft 404 and sleeve 408 are aligned and then the shaft 404 is inserted into the sleeve 408 so that the holes 414 are in register as seen in FIG. 11 and the corner of the booth framework 412 is assembled with only the nuts and bolts being inserted thereafter to secure the parts together.

(44) This assembly procedure applies to all the joints of the framework 412 with the exception of the upper crown portion 416 thereof on some models of the booth 410, as well as the tank and pump stands which may have fully welded joints.

(45) Once assembled all the joints conceal the lug which fits like a hand in a glove with the framework material.

(46) This kit thus allows for quick assemble and ease of dismantling of the booth of the invention.

(47) Still further, the sleeves and shafts are standardized which makes for ease of manufacture, maintenance, and parts supply in the event of any part of the framework being lost or damaged.

(48) FIG. 12 shows, by means of arrows, the assembly of the booth framework from the sleeves and shafts described above and shown in FIGS. 10 and 11.
