At the outset, it is pointed out that the apparatus may be constructed to be fitted to a door which opens from the left hand side or the right hand side and the device will be constructed accordingly.
- It will further be understood that the device may be used on the inside or outside of a door and may be used on a door which opens inwardly or outwardly.
- The apparatus or
device 10 is for dispensing a spray of disinfectant liquid onto ahandle 11 or a push plate (not shown) mounted on a door 12 (FIG. 4 a). - The
apparatus 10 comprises a housing having abase plate 13 and acover 14. InFIGS. 1-3 , there is shown aframe 15 which is mounted to thebase 13. Theframe 15 has aslot 16 for accommodating a slideable arm (slider) 17 which can slide axially in theslot 16. - A
spray head 18 is disposed at one end of theframe 15. An actuatingarm 19 is mounted at the opposite end of thebase 13 to thespray head 18 and projects laterally outwardly from theapparatus 10. The spray head is connected by aconduit 20 to a container ofdisinfectant liquid 21 which is also mounted on thebase 13. Thecontainer 21 has anipple 22 which is accommodated in aboss 23, theboss 23 having aneedle 24 which is connected to theconduit 20 so that a replacement bottle can be readily engaged with theneedle 24 when a new bottle is being put in place. It will be appreciated that thecontainer 21 in this embodiment could be a flexible bag or pouch type of liquid container, or a solid walled container. - The
base 13 and thecover portion 14 together provide an enclosed housing to secure the various components of the apparatus. - The construction shown in
FIG. 1 is to be mounted on a door which opens from the right hand side whereas the construction shown inFIGS. 2 and 3 is to fitted to a door which opens on the left hand side. - As shown more clearly in
FIGS. 2 and 3 , thespray head 18 is disposed between anend wall 25 of theframe 15 and the slidable arm (slider) 17. The spray head has anaperture 26 for spraying a charge of liquid downwardly through an opening in the housing onto a door handle or pushplate 11. - The
actuating arm 19 has a doorframe engaging portion 30 and acam portion 31. Thecam portion 31 is disposed within the housing and the door engaging portion projects forwardly of the plane of the base 13 which abuts the door surface to which it is fitted in use. Theactuating arm 19 is pivotally mounted on the base 13 at 32. - The
cam portion 31 engages acam surface 33 on theslider 17 so that movement of thecam portion 31 against theslider 17, causes the slider to move against thespray head 18 and cause activation of the spray head to produce a spray of liquid. - As shown more clearly in
FIGS. 3 and 4 a-4C, in the open position of the door, the doorframe engaging portion 30 of theactuating arm 19 projects slightly adjacent the edge of the door as shown clearly inFIG. 4 b. As the door is closed (FIG. 4 c) the doorframe engaging portion 30 engages with thedoor frame 40 causing theactuating arm 19 to pivot and causing thecam portion 31 to engage thecam surface 33 of theslider 17. Theslider 17 therefore moves against the spray head to activate the spray head and produce a spray of liquid onto thehandle 11. When the door is opened again, a spring bias in the spray head pushes against theslider 17 causing theactuating arm 19 to pivot and return to its initial position. - It will be appreciated that the
handle 11 may be freely rotatable about its vertical axis. In another embodiment, the handle may be mounted horizontally or it may be a conventional handle. - In this embodiment, when it is desired to replace the container of
disinfectant liquid 21, it is a simple matter to remove thecover 14 from the base of the unit and to replace thecontainer 21. - Referring now to
FIGS. 5-12 there is shown therein another embodiment of the invention. In this embodiment, the housing has a base 13 which holds a container ofdisinfectant fluid 21 and thecontainer 21 is moveable within the housing. The container is pivotably mounted on thebase 13 by aboss 50 on the base projecting through anaperture 51 in the container. Thecontainer 21 has mounted thereon aspray head 18 and thespray head 18 abuts aside wall 52 of thebase 13. Theactuating arm 19 is mounted on the base 13 so that thecam portion 31 engages aside wall 53 of thecontainer 21. Thespray head 18 may be attached to thecontainer 21 via aboss 54 or indeed may be integral with thecontainer 21. - In this embodiment the
container 21 is of a solid wall construction being substantially rigid to enable it to be moved by theactuating arm 19. Thecontainer 21 andspray head 18 may be supplied as a refill unit, enabling easy replacement of the disinfectant when it needs to be replenished. - In
FIGS. 10 , 11 and 12 there is shown the apparatus ofFIG. 5 mounted to adoor 12. In this embodiment, the apparatus is arranged for mounting to a left hand opening door. InFIGS. 7 and 8 , there is shown the door in the open position (FIG. 7 ) and in the closed position (FIG. 8 ). When the door is closed, the doorframe engaging portion 30 of theactuating arm 19 abuts against thedoor frame 40 causing theactuating arm 19 to pivot so that thecam portion 31 engages against theside wall 53 of thecontainer 21 causing the container to move within the housing and to operate thespray head 18. When the door is opened, the bias of thespray head 18 acts against thecontainer 21 to move the container to its initial position and to also move theactuating arm 19 to its initial position as shown inFIG. 7 . It will be noted inFIG. 7 that the doorframe engaging portion 30 of theactuating arm 19 projects forwardly of the plane of the surface of the door on which the apparatus is mounted. - This embodiment of the invention has considerable advantages particularly in that the number of parts is considerably reduced and therefore the cost of production is low and the reliability of the apparatus is extremely good.
- The embodiments of the invention have the advantage that they provide a simple inexpensive and reliable apparatus to enable a spray of disinfectant liquid to be applied to a door handle, door push plate or other door surface when a door is opened or closed. In this regard, it will be appreciated that the apparatus could be arranged to apply the spray of disinfectant liquid onto the door handle when the door is being opened rather than when it is being closed.

FIGS. 13 and 14 there is shown therein another embodiment of a cleaning device generally indicated at 60 according to the invention. This embodiment is useful where it is desirable to use a flexible bag or pouch type of liquid container or reservoir. The device 60 has abase 13, the lower portion of which has a moveable slidable arm (slider) 70 mounted thereon. Aspray head 71 is disposed at one end of the base and anactuating arm 72 is mounted at the opposite end. Aflange 73 on thespray head 71 abuts against a sidewall of thebase 13. Thespray head 71 is connected by aconduit 74 via aboss 75 to a flexiable bag or pouch type of container shown in dotted outline at 76. - The
slider 70 has acam surface 77. Theactuating arm 72 is mounted on thebase 13, as described previously in relation to the previous embodiments and also in relation to the following embodiments. Acam portion 79 of theactuating arm 72 engages thecam surface 77 of theslider 70 so that movement of thearm 72 andcam portion 79 causes theslider 70 to move against thespray head 71 and cause activation of the spray head, to spray a disinfectant liquid onto a door handle or door push plate. - The
conduit 74 may be engaged in spring urgedclips 80 mounted on theslider 70. It is envisage that the flexible bag orpouch 76, theboss 75 together with theconduit 74 and thespray head 71 may if desired be supplied as a “refill” so that when abag 76 is empty it may be removed including theconduit 74 andspray head 71 and replaced with a complete new system. - It will be clear therefore that the invention further provides a refill container of disinfectant fluid having a conduit connected to a spray head, for a cleaning device.
- Further the invention provides a refill container of disinfectant fluid having a conduit for connecting to a spray head.
- It will be clear that the actuating
member 72 is similar to that of the actuatingmember 19 described in relation to the other embodiments and that the components and parts of the various embodiments are interchangeable. - Referring now to
FIGS. 15 and 16 there is shown another embodiment of acleaning device 85 according to the invention having an actuating arm for an outwardly opening door according to the invention. In this embodiment the interior of thedevice 85 may be similar to the other embodiments described herein and in this case the main difference is that theactuating arm 86 is generally wedge shaped. In the closed position of the door, thearm 86 is pivoted inwardly against the bias of the spray head by the door frame so that the spray is activated as the door is closed and when the door is opened the arm is released to ready the apparatus to spray again when the door is next closed. - Referring now to
FIGS. 17-20 there is shown another embodiments of cleaningapparatus 90 according to the invention. In this embodiment theactuating arm 85 is separate from the housing. Theactuating arm 85 is mounted in the interior of the door structure and comprises a spring urgedarm 85 which has an end which engages with the door frame. The actuating arm has anextension part 87 havingseveral holes 88, to receive atrigger pin 89 which projects from the rear of theapparatus 90. Thetrigger pin 89 is engaged inside thehousing 90 with a slidable arm (slider) not shown. - The
door 95 has ahole 96 cut in it to enable thetrigger pin 89 to engage with one of theholes 88 in theextension part 87 of theactuating arm 85. - Therefore, when the door closes the
arm 85 is pushed inwardly into thedoor 95 and with thepin 89 engaged in ahole 88, in theextension part 87, the pin moves the slider (inside the housing 90) to activate the spray head. - It will be appreciated that suitable means may be provided to enable positional adjustment of the spray head, in all embodiments of the invention, so that the angle of the spray can be adjusted for optimal effect. Such positional adjustment of the spray head can be achieved, for example, by providing suitable pins or holding elements on the base 13 which enable the spray head to be located and held as desired.
- The invention has particular applications in many environments including hospitals, restaurants and other areas where members of the public are present. The invention will greatly assist in minimising and eliminating the spread of bacteria and infection from doors, door surfaces and door handles by reducing or eliminating contamination on the surfaces which are regularly touched by many individuals.
- The invention also has the advantage that it does not require a cam mounted on the door frame to actuate the spray head since the actuating arm can engage directly with the door frame. In particular, the actuating arm can be made of a plastics material which is suitably contoured and moulded to minimise any impact with the door frame.
- The invention is not limited to the embodiment described herein which may be modified or varied without departing from the scope of the invention.
