(Cl. 222-180) ABSTRACT OF THE DISCLOSURE A body secured adjacent an edge of a hingeably mounted door having an inlet passage and means communicating therewith for securing an aerosol insecticide container to the body in communication with the inlet passage, an outlet passage and means secured thereto for dispersing a fluid and a resilient door engaging means secured to an actuator for being engaged by the door when the door is opened and opening the valve of an aerosol bomb to spray insecticide adjacent the door is disclosed.

Background of the invention Field of the invention-This invention relates to valve actuators and more particularly to actuators for operation automatically upon engagement by a door.

Description of the prior art.--Plunger operated valves are well known in the art; however, valves especially adapted for being engaged by a hingeably mounted door for automatically opening the valve have not been found useful for dispersing the contents of an aerosol bomb in the space adjacent the door heretofore. Numerous valves are shown in the prior art constructed and arranged for inclusion in conduit systems of comparatively complex construction. Valves which are specially constructed for being operated by the opening of a door and for securing an aerosol container adjacent the door are, to my knowledge, not known in the prior art.

Summary The present invention relates to a door and valve actuator combination in which a body is secured to the facing adjacent the door, an aerosol container is secured in communication with a passage in the body, means for dispersing the contents of the aerosol container to the space adjacent the door and means received in the body for being operated by the opening of the door for opening the aerosol valve to permit dispersion of the fluid therein.

A novel aerosol holder and valve actuator forms the subject of this invention which includes the following features, of which are objects of the invention:

A holder body having inlet and outlet passages, means for detachably securing an aerosol container in communication with the inlet passage and means for securing fluid dispersing means to the outlet passage and actuator means in the body for engaging and opening the aerosol valve when a door is opened;

A holder including a body having inlet and outlet passages therethrough, means for detachably securing an aerosol container in communication with the inlet passage and means for dispersing the contents of the aerosol container secured to the outlet passage and a plunger slidably received in a passage in the body for engaging and opening the aerosol valve upon being engaged by a door when said door is opened; and

A resilient door engaging member which lies in a plane substantially parallel to the plane of the door when closed for being engaged by the door for actuating a valve to disperse the contents of an aerosol bomb into the space adjacent the door.

The specific construction and arrangement of parts constitutes a further object of the invention.

FIGURE 4 is a perspective view in detail of the inlet tube of FIGURE 3 shown in perspective.

Description of the preferred embodiment This invention comprises, in combination, -a door 12 which preferably is mounted hingeably in a frame which includes a facing 14 adjacent a side of the door 12. An aerosol container 16 is hingeably mounted to holder body 10 which includes a resilient actuator 18 which will be described in greater detail hereinafter; A fluid dispersing nozzle 20 is secured to an outlet passage in the body 10.

Referring with particularity to FIGURES 2 and 3, the device of this invention comprises a body 22 which has therein an outlet passage 24 and a second outlet passage 25, if desired. Preferably, the ends of outlet passages 24 and 26 are threaded at 23 and 30, respectively, for threadably receiving coupling half unions 32 and 24 or another convenient fitting as desired. As shown in FIGURE 3, dispersing nozzle 20 may conveniently be secured to fitting 32 and arranged as shown in FIGURES 1 and 2. Body 22 also includes an inlet passage 36 and an additional passage 38, the function of which will be described hereinafter. Inlet passage 36 is preferably threaded at 40 and the additional passage 38 is preferably threaded at 42 for threadably receiving fittings as will be described.

In a preferred form, the body also includes a pair of brackets 44 which includes an aperture 46, and 48, which includes an aperture 50, for providing convenient means to secure the body to the facing adjacent the door.

As shown best in FIGURES 3 and 4, an inlet tube or conduit 52 extends into inlet passage 36, and is provided at one end with outlet relief ports 54 and at the other end with a flanged gasket holder 56. A threaded sleeve 58 is received on the exterior end of conduit 52 and a resilient gasket 60 is secured in threaded sleeve 68, preferably annularly between the flange 56 and the wall of fitting 58. A fitting or adaptor 62 fixedly secures the conduit 52 in position extending inwardly through the inlet passage 36, as shown in FIGURE 3.

As also shown in FIGURE 3, the means for opening the aerosol container 16 comprises an actuator which includes a plunger 64- which is slidably received in the additional passage 38. Plunger 64 is provided with a groove 66 for receiving an O-ring 68 which coacts between groove 66 and the walls of passage 38 to form a seal therebetween. The interior end of the plunger is tapered as shown at 70 for selectively comating with a complementarily tapered interior portion of passage 38. A plunger guide and keeper 72 is threadably received in the threaded end 42 of the additional passage 33. The keeper 72 is provided with a ring flange which engages the exterior end of plunger 64 to limit the outward movement of the plunger in the holder body.

A rigid actuator rod 74 is secured to the exterior end of plunger 64.

A highly important feature of the present invention is the provision of a resilient door engaging means 18 which includes an elongate resilient member 76 which is substantially coaxial with plunger 64 and a resilient tip 78 secured on the distal end of the resilient elongate member 76. As shown in FIGURE 1, and in FIGURE 2, the resilient door engaging means 18 lies in a plane which is substantially parallel to the door in its closed position and is engaged by the door when the door is opened and moves when the door is opened to move the plunger inwardly in the passage 38 in valve body 22. A rigid elongate member 80 is secured to the other end, the interior end, of plunger 64 and is specially constructed and arranged for engaging a valve 82 which is conventionally provided in aerosol containers such as aerosol container 16. When the door 12 engages the tip member 78 and the resilient elongate member 76 and moves the plunger 64 inwardly in passage 38, the rigid elongate member 80, which is, in the preferred embodiment, coaxial with th plunger and with the opening of the aerosol container, engages the valve 82 of the aerosol container and thereby opens the valve 82 to permit escape of the contents of the aerosol container. The plunger 64 may be resiliently biased outwardly in passage 38 by a spring 84 to maintain the plunger in the position wherein the valve is closed normally.

Operation In operation, each time door 12 is swung open it engages the resilient actuating means 18 which, acting through rod 74, moves plunger 64 inwardly in passage 38 which in turn moves the rigid elongate means 80 toward the valve 82 of the aerosol container 16, thereby opening the valve 82 to permit the fluid to flow from aerosol container 16, through conduit 52 and consequently through inlet passage 36, through ports 54 and through outlet passages 24 and 26, if two passages are provided. The fluid is then dispersed through dispersing nozzle 20 which is secured by means of fitting 32 in communication with passage 24. An additional dispersing means or conduit carrying the fluid to a desired location, such as a light 01' the like, may be secured to fitting .34 in the manner described with respect to dispersing means 29.

It Will be seen from the foregoing that a novel and highly useful valve system has been provided which is especially adapted and constructed for automatically dispersing the contents of an aerosol bomb in the vicinity of a door each time the door opens. The invention has particular utility as a means for dispersing an insecticide in the space adjacent the door each time it is opened. The device is particularly valuably used around the barns, dairies, industrial establishments and the like where cleanliness and freedom from insects is of great importance. The invention is not limited to these applications, however, and may be used around dwelling houses, business establishments and the like. In addition to dispersing insecticides, which constitutes the primary utility of the invention, the invention may be used to disperse deodorants, perfumes and the like around the doors of residential buildings and business and industrial establishments. For example, the device may be used to disperse a deodorant into a bathroom each time the door is opened, as when a person enters and when a person leaves. Thus it will be seen that an invention of great practical utility has been described.

While the invention has been described, abstracted, and summarized in very specific terms to aid in the ready understanding of the invention and to comply with the disclosure provisions of the patent statutes it will be realized that while a single preferred embodiment has been described the scope of the invention is intended to be limited only by the appended claims and that the disclosure and the drawings are intended merely as exemplary of the invention and not in a limiting sense.
