1. Field of the Invention
The present invention relates to actuating holders for aerosol containers and more particularly pertains to a new spray can trigger system for actuating the spray head of an aerosol container such as a spray can.
2. Description of the Prior Art
The use of actuating holders for aerosol containers is known in the prior art. More specifically, actuating holders for aerosol containers heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. Nos. 4,579,258; 4,098,436; 3,734,357; 3,112,849; 2,803,383; and U.S. Pat. No. Des. 189,323.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new spray can trigger system. The inventive device includes a base for resting an aerosol container thereon. An elongate rod upwardly extends from the base. An elongate top member is coupled to the rod. The proximal end of a lever arm is pivotally coupled to the top member. A distal end of the lever arm is designed for positioning above a spray head of the aerosol container resting on the base. A handgrip is downwardly depended from the top member. A pivot extent is pivotally coupled to the handgrip and has an elongate trigger downwardly depending therefrom. A pull loop is upwardly extended from the pivot extent. The lever arm and the top member are extended through the pull loop.
In these respects, the spray can trigger system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of actuating the spray head of an aerosol container such as a spray can.

Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new spray can trigger system embodying the principles and concepts of the present invention will be described.
As best illustrated in FIGS. 1 through 4, the spray can trigger system generally comprises a base for resting an aerosol container thereon. An elongate rod upwardly extends from the base. An elongate top member is coupled to the rod. The proximal end of a lever arm is pivotally coupled to the top member. A distal end of the lever arm is designed for positioning above a spray head of the aerosol container resting on the base. A handgrip is downwardly depended from the top member. A pivot extent is pivotally coupled to the handgrip and has an elongate trigger downwardly depending therefrom. A pull loop is upwardly extended from the pivot extent. The lever arm and the top member are extended through the pull loop.
In closer detail, the spray can trigger system is designed for use with a generally cylindrical aerosol container 10 having a top and a bottom, and a depressible spray head 11 mounted to the top of the aerosol container. Typically, the bottom of the aerosol container has a cavity 12 therein.
The trigger system is an assembly comprising a planar base 13 having arcuate proximal and distal ends 14,15, and a pair of straight sides 16,17 extending between the proximal and distal ends of the base. The distal end of the base has a radius of curvature greater than a radius of curvature of the proximal end of the base so that the sides of the base converge towards one another in a direction towards the proximal end of the base.
The bottom of the aerosol container is rested on the base adjacent the distal end of the base such that the aerosol container upwardly extends from the base. Preferably, the base has a generally disk-shaped stage 18 upwardly extending therefrom adjacent the distal end of the base. The cavity of the bottom of the aerosol container receives the stage of the base therein such that the stage holds the aerosol container in position on the base.
In an ideal illustrative embodiment, the base has a length defined between the proximal and distal ends of the base between about 7 1/2 inches and about 8 inches to provide an optimal amount of stability to the trigger assembly when rested on a resting surface with the aerosol container resting on the base while also not being too long to hinder use of the trigger assembly in the hand of a user.
An elongate rod 19 upwardly extends from the base adjacent the stage such that the rod is positioned between the stage and the proximal end of the base. Preferably, the rod is extended substantially perpendicular to the base. The rod has opposite top and bottom ends with the bottom end of the rod being coupled to the base.
An elongate top member 20 is coupled to the top end of the rod and is extended substantially perpendicularly from the rod in a direction towards the proximal end of the base. The top member has a free end opposite the top end of the rod.
An elongate lever arm 21 is included having opposite proximal and distal ends 22,23. The proximal end of the lever arm is pivotally coupled to the free end of the top member by a mushroom-head pin 24 upwardly extending from the free end of the top member and through a hole at the proximal end of the lever arm. Preferably, the proximal end of the lever arm is biased towards the free end of the top member by a coiled spring 25 disposed around the mushroom-head pin between the head of the pin and the proximal end of the lever arm.
The distal end of the lever arm is extended upwardly and outwardly in a direction towards the distal end of the base from the proximal end of the lever arm. The distal end of the lever arm is positioned directly above the spray head of the aerosol container. In use, the distal end of the lever arm is designed for pivoting downwards towards the spray head of the aerosol container to depress the spray head to spray the contents of the aerosol container therefrom. Preferably, the lever arm has a pair of bends 26,27 located towards the distal end of the lever arm for making a more parallel contact between the distal end of the lever arm and the spray head of the aerosol container.
A handgrip 28 is downwardly depended and coupled to the top member adjacent the free end of the top member. In use, the handgrip is designed for grasping with the hand of a user to hold the trigger assembly.
A pivot extent 29 is pivotally coupled to an upper portion of the handgrip and extended from the handgrip towards the rod. The pivot extent is pivotable about an axis substantially perpendicular to the rod such that the pivot extent pivots in a plane substantially parallel to the rod.
An elongate trigger 30 is downwardly depended from the pivot extent and positioned between the handgrip and the rod. In use, the trigger is designed for squeezing with the hand of the user towards the handgrip to pivot the pivot extent downwards.
The pivot extent has a distal end 31 opposite the handgrip and located towards the rod. A generally annular pull loop 32 is upwardly extended from the distal end of the pivot extent. The pull loop has upper and lower portions with the lower portion of the being coupled to the distal end of the pivot extent. The lever arm and the top member is extended through the pull loop with the lever arm positioned directly beneath the upper portion of the pull loop. In use, pivoting downwards of the pivot extent by pulling on the trigger moves the pull loop downwards which in turn forces the distal end of the lever arm to move downwards to depress the spray head of the aerosol can.
A generally L-shaped retaining clip 33 is preferably included having an upper elongate portion 34 and an end portion 35 downwardly extending from the upper elongate portion of the retaining clip. The upper elongate portion is rotatably mounted to the top member adjacent the top end of the rod and above the pivot extent by another mushroom-head pin 36 upwardly extended from the pivot extent and extended through generally coaxial holes in the top member and upper elongate portion of the clip. This allows rotation of the retaining clip about the pin in a plane parallel to the top member.
The end portion of the retaining clip is positioned between the top end of the rod and the distal end of the base. In use, the end portion of the retaining clip is inserted into an annular lip 37 upwardly extending around the top of the aerosol container to hold the aerosol container between the base and the retaining clip. The rotatable mounting of the retaining clip providing a means for moving the retaining clip to release it from the lip of the aerosol container or to mount to a replacement spray container.
The retaining clip is preferably biased downwards to bias the end portion of the retaining clip down by a coiled spring 38 disposed about the mushroom head pin between the top member and the pivot extent to help securely hold the aerosol container between the retaining clip and the base.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
