DOOR MOUNTED SPRAYING DEVICES BACKGROUND OF THE INVENTION The present invention relates to a door-supported spraying device of the type that is attached to and is carried by a movable door and is adapted to spray a deodorant or other desired fluid into the room that is closed by the door, this operation being performed each time that the door is closed. A spraying device of this general character is shown in my US. Pat. No. 3,344,959 and the present invention relates primarily to an improved means for mounting a unit of this kind on a door.
The improved construction includes a supporting clip for hangingthe spraying unit from a top edge of a door and to secure the assurance of operation as well as to improve the ease of installation of the unit. It is well known that the gap between the top edge of adoor and the door frame or jamb is not always uniform. This is due to installation, shrinkage or for many'other reasons and may vary up to one-quarter of an inch, or even more. As a result, in order to have a door-spray unit operate properly, shims were often required and this 7 made it difficult for the user to install it properly and this affected consumer acceptance.
The present invention eliminates the use of any screws or other fasteners to the door or the door frame for installation of the spraying device. Installation can be made quickly by anyone without the use of tools. No adjustments or additional brackets are required for the proper operation of the device, whether the door swings in or out. The invention involves the employment of a metal clip which has a part fitting over the top of the door, such clip supporting the housing of the spray device and automatically tending to adjust the unit to the proper position, thereby improving its performance. The metal clip, used as above stated, has flexibility and acts as a spring and will adjust itself to the size of the door gap.
More particularly, the invention contemplates the provision of a substantially U-shaped springy metal clip which embraces the top of a door and is provided with lug portions fitting into slots in the housing to thereby attach the clip to the housing. The clip has spring means which enable it to adjust itself on the door so that the position of the operating lever of the sprayer with respect to a part of the door frame to secure the required spraying effect each time that the door is closed, will be assured.
DESCRIPTION OF THE INVENTION Reference is to be had to the accompanying drawings, wherein an illustrative embodiment of the invention is shown and in which:
FIG. 1 is a side elevational view of a spray device made in accordance with the invention;
FIG. 2 is a front elevation of the same;
FIG. 3 is a top plan view of the same;
FIG. 4 is a perspective view of the clip for fitting the unit at the top of a door;
FIG. 5 is a rear view of the housing, with the clip removed in order to show the slots provided for the reception of parts of the clip;
FIG. 6 is a sectional view, taken substantially on the line 6-6 of FIG. 2, looking in the direction of the arrows;
FIG. 7 shows the device in place on a door-and the door being in a closed position. to actuate the sprayer;
FIG. 8 shows the device with the door slightly open and just beginning to be moved to a closed position;
FIG. 9 shows the device fitted with a modified form of mounting clip, and
FIG. 10 is a perspective view of the clip shown in FIG. 9.
Referring to'the drawings, there is shown therein a housing or casing generally indicated at 1 and which can be composed of plastic, metal or other suitable material. It includes a base portion 2 and a cover or closure member 3 that is telescopically fitted over the base. The container thus produced contains a spray holder or bottle, such as is disclosed in my US. Pat. No. 3,344,959 and a part of such container is shown at 3a in FIG. 6. Such a spray container includes a plunger 6 which when depressed will spray out some of its contents through a hole 4 provided in the front wall of the portion 3 of the housing.
Pivotally mounted at 11a is lugs 12 on the base 2 near the top of the base is an operating lever 5 which has a part 6 projecting above the base portion and in such a position that when the unit is mounted at the top of a door 7 and the door is brought to a close, the door jamb or frame 8 will contact with the projecting part of the lever and will pivot the lever in such a manner as to cause it to depress the plunger of the spray container thus causing the ejection of some of the contents of the container into the room for which the door is a closure.
The housing 1 is mounted on a door by means of a springy, metallic clip generallyindicated at 9. The clip is roughly of inverted U-shape and it thus includes substantially parallel leg portions indicated respectively at 10 and l I. Said leg portions are integrally connected by a web 16. When the'clip is fitted on the housing, the web 16 will extend over the top of the door as seen in FIGS. 7 and 8.
The leg 10 of the clip is bifurcated to divide it into a pair of laterally-projecting lugs 13, these lugs being received in slots 14 (FIG. 5) provided in the base 2 of the housing adjacent to the top of the same. The lugs 13, projecting laterally from the leg 10, are provided with struck-out tabs 17 that engage in openings 18 (FIG. 6) formed in the top wall of the base 2. This arrangement firmly attaches the clip to the housing. The clip has an aperture 21 in the leg 10 between the lugs 13 and such aperture provides clearance for the part 6 of the operating lever 5 and permits it to be pivotally moved by contact with a part of the door frame.
Near the top, the leg 10 of the clip is formed with a pair of rounded nodes 22 which come into initial contact with the door frame stop, or molding thereon when the door is brought to a close. This insures the proper contact with the door frame stop, or molding on the closure of the door to thereby cause the positive movement of the spray lever.
The operation of the spraying device will be clear from FIGS. 7 and 8. FIG. 8 shows the door just about to assume a closed position and the operating lever 5 not yet depressed. FIG. 7 shows the door in closed position and in contact with the door frame 23. The flexibility of the legs 10 and 11 of the clip 9 permits movement of the door when the nodes 22 contact with the stop 8, for a distance sufficient for the door to contact with the part 6 of the lever 5 and swing the lever on its pivot 11a to cause it to depress the plunger of the spray container and result in the ejection of a mist of the deodorant into the room for which the door is a closure. The housing 1 is always fitted on a door in such a way that it faces into the room and this is so whether the door swings inwardly or outwardly.
The clip shown at 25 in FIGS. 9 and 10 is a slightly modified arrangement. It has a leg 26 and a second shorter leg or offset 27 provided with the projecting lugs 28 which enter into the slots 14 to attach this clip to the base of the housing 1. The legs 28 have struckout tabs 29 similar to those shown at 17 and they are used for the same purpose.
Located centrally of thetop of the clip 25 isa struckout and downwardly projected tongue 30 constituting a leaf spring. In FIG. 9 the manner in which the clip 25 operates is shown. The springy tongue 30 on the clip contacts with the top edge of the door 7 and this assures that the projecting part 6 of the operating lever will be in position to contact with the edge of the door stop 8 on the door frame 23 and result in the desired spraying. This is of importance since in many cases the unit, when fitted on a door, might not be positioned high enough to enable the part 6 of the lever 5 to contact with the door frame 23. The resiliency of the tongue, causing it to act as a leaf spring, compensates for any difference in spacing between the top of the door and its frame.
