Levy, 2930 Rockaway Ave., Oceanside, N.Y., and Harry M. Durst, 552 Brookside Ave., Freeport, NY.

Filed Feb. 9, 1965, Ser. No. 431,281 10 Claims. (Cl. 222180) The present invention relates to a device for the automatic treatment of the air in a room and, more particularly, to a device for the automatic spraying of the air in a room, as with a sterilizing, de-odorizing or perfuming spray.

It is an object of the present invention to provide a device, including a pressurized spray dispenser that is operable by the movement of a door of an enclosed space, that will cause the discharge of spray from the dispenser into the space, each time the door is used, preferably each time the door to the space is closed.

It is another object of the present invention to provide a device, of the character described, that is actuated directly and solely by the door, to produce a spray into the space upon the movement of the door.

It is still another object of the present invention to provide a device, of the character described, which is of relatively simple and economical construction and simple and easy to install.

It is a further object of the present invention to provide a device, of the character described, which is sure and certain in operation.

It is a still further object of the present invention to provide a device, of the character described, which permits the easy and ready replacement of spent pressure dispensers.

The foregoing and other objects and advantages of the device of the present invention will become more readily apparent to those skilled in the art from the embodiments thereof shown in the accompanying drawing, and from the description following. It is to be understood, however, that such embodiments are shown by way of illustration only, to make the principles and practice of the invention more readily comprehensible and without any intent of limiting the invention to the specific details therein shown.

In the drawings:

FIG. 1 is a fragmentary, perspective view showing one embodiment of the device of the present invention as installed for operation by a door, ready for operation, the door being shown in open position;

FIG. 2 is a side elevation, on an enlarged scale, of an installation of the device of the present invention, on a wall above a door; the device being shown in non-operating position;

FIG. 3 is a view similar to that of FIG. 2, of the device, with the installation shown in spraying position;

FIG. 4 is a front elevational view of the device of the present invention, shown in FIG. 2; partly broken away to illustrate structural details; and

FIG. 5 is a fragmentary side elevation of the lower portion of the pressure-dispenser supporting frame of the invention, with the dispenser-bottom supporting member shown in open position for the insertion and removal of a pressure-dispenser.

Referring now, in greater detail to the embodiment of the invention illustrated in the drawings, the same is ice shown to utilize a pressure dispenser, generally designated as 10, consisting of a conventional, cylindrical container 12, having a domed top section, 14, mounting a depressible, valve-opening, discharge nozzle head, 16, having the spray output, 17, the head 16 being normally resiliently held in upwardly displaced, valve-closing position.

The invention further comprises a holder for the pressure dispenser 10, generally designated as 18, which is securable against a wall, 20, immediately above the opening 22, for a door, 24.

The pressure-dispenser supporting frame may preferably be of open-work construction, comprising an upright bar, 26, having screw openings, 28, and is preferably of a height substantially equal to the height of the container 12 of the pressure dispenser 10, exclusive of the nozzlehead 16.

The bar 26 has secured thereto, in normal relation thereto, a pair of annular members or rings, 30, of equal diameter, which are disposed in spaced relation to the ends of the bar 26 and spaced apart from one another a distance less than the height of the cylindrical portion 14 of the container 12. The two rings 30 are connected, at a point diametrically opposed to the bar 26, by a second bar, 32, which extends from the upper of the rings 30 to a point below the lower of the rings 30; the rings and bars forming a cylindrical housing for a pressure dispenser 10.

A base or bottom closure bar, 34, of a size equal approximately to the outer diameter of the rings 30, is hinged by one end, as at 36, to the lower end of the bar 26, for movement into and out of position transverse to the axis of the frame 18, and is provided with an offset portion, 38, at its other end, which is adapted, when the bar 34 is in horizontal or transverse position, to be disposed against the lower projection of bar 34; the offset end 38 and projection of bar 34 being provided with the respective openings, 40 and 42, for receiving means, such as a cotter pin, 44-, for securing the bar in transverse position, across the bottom of the frame 18 for supporting a dispensing container 10 disposed within the frame.

I-Iingedly secured to the upper end of the bar 26, as at 46, is one end of a bar, 48, that rests on and is supported by the nozzle-head 16 of the dispenser 10, preferably in slightly upwardly-slooping relation. The bar 48 has an extension, 50, which preferably is offset slightly downwardly relative thereto; the nozzle-head 16 being, pref erably, disposed in the angle formed by the bar 48 and extension 50 and contacted by both of them. The bar extension 50 is provided, at its other end, with a depending extension, 52, ofr'set relative to the extension 50* at such angle that the bar extension 52 is normally disposed alongside of the frame bar 32, in slightly spaced relation thereto, and, when bar sections 48 and 50 rest on a nozzle head 16, in downwardly divergent relation to bar 32. The bar extension 52 may be of a length to terminate substantially coequally with the lower end of the bar 32 and has secured to its lower end portion a strip, 54, of stifily resilient material, such as rubber, which extends a distance below the lower end of bar 32.

For use, the dispenser supporting frame 18 is attached to the wall 20 by bar '26, as by means of screws, 56, passing through the screw-opening 28 in the bar. The frame on housing 18 is so attached that the lower end of bar extension 52 clears the door opening 22 but the resilient strip 54, projecting therefrom, overlies such door opening.

To dispose a dispenser 10 Within the supporting frame 18, the cotter pin 4-4, or like device, is removed so that the bottom closure bar 34 swings downwardly to clear the way into the frame. The dispenser is then inserted, nozzle-head 16 up, through the bottom of the frame, and the bar 34 is raised and interengaged with the projection of the bar 32 by means of the cotter pin, or the like. It may here be stated that the weight of bar 48 with its extensions 50' and 52 is such that it is insuificient of and by itself to cause a valve-opening depression of nozzle head 16, so that such nozzle head will remain in its normal upwardly-biased position and raise bar 48 and its extensions 50 and 52, so that the latter is disposed at a divergent angle to the axis of the frame 18.

It will be clear that when the frame 18 containing a dispenser 10 is in place and the door 24 is opened, the top edge of the door will engage the projecting resilient strip 54 and will move and offset it and the bar extension 52 outwardly and upwardly to clear the door top without any difiiculty and without any effect on the pressure dispenser 10. However, when the door 24 is closed, its edge will engage against the outer face of the strip projection 54 and press it inwardly towards the frame 22, causing the strip and the bar extension to which it is attached to be pushed towards the supporting frame 18 and thereby lowering the bar section 48 and its extension 50 onto the nozzle head 16, to depress the same, causing a discharge of spray through the valve of the pressure dispenser that is opened by such nozzle head movement. It will be understood that the resistance of the resilient strip when added to the weight of the bar sections 48, 50 and 52 will be sufficient to cause the depression of the nozzle head 16 and that, when the nozzle head is in lowermost depressed position its resistance against pressure will be sufficient to overcome the resistance of the resilient strip 54 to bending, so that the latter is resiliently offset to permit clearance of the door under it for shutting; the resilient strip 54 returning to normal, straight position after it is cleared by the door.

This completes the description of the device of the present invention for the automatic discharge of spray into an enclosed space. It will be readily apparent that such device is capable of utilizing conventional pressurized dispense-rs that are now readily available on the market; that such device requires the use, in combination with such pressurized spray dispensers, of a simple supporting and actuating structure that is economical to manufacture, easy to install, and sure and certain in its operation.

It will also be apparent that the installation of the de vice of the present invention will in no way interfere with the function of the door by which it is activated, and that it will not unduly affect the appearance of the space in which it is installed.

It will be further apparent that numerous modifications and variations in the device of the present invention may be made by anyone skilled in the art, in accordance with the principles of the invention hereinabove set forth Without the exercise of any inventive ingenuity. We desire, therefore, to -be protected for any and all such variations and modifications that may be made within the spirit of the invention and scope of the claims hereto appended.
