Description

Gun Handle and Trigger Attachments

The present invention relates to a spray gun handle and trigger attachment, particularly for use with an aerosol-type container for spraying a targeted area.

An aerosol container is a dispensing system designed to transform a liquid product into a finely dispersed mist by propelling it with a pressurized propellant liquid stored within it. Aerosol containers are widely used in hygiene products, cosmetics, cleaning products and industrial products. However, there are some inconveniences when handling aerosol containers. For example, push button valve type aerosol containers may leak near the button after a period of continuous use. The contents of the aerosol container may be chemical compounds that are harmful to human health, so it is necessary to avoid direct contact with said chemicals. Many aerosol containers today have incorporated spray guns. A spray gun connects the aerosol container to a handheld device having a trigger assembly for actuating the aerosol container. The trigger assembly is typically activated with the user's finger, and prolonged use can lead to finger fatigue, which can lead to inconsistent spraying of the contents from the aerosol container.

A number of technologies have been implemented to improve existing spray gun handle attachments. One such technology is disclosed in United States Patent (Publication No. US9808816B1 ), which discloses a portable, self-contained, hand-held spray gun system. The spray gun system includes a spray gun and a replaceable container. The spray gun has a handle, a machine tube and a trigger. The replaceable container contains the sprayable substance. When the trigger is squeezed, the sprayable substance, which flows under pressure from the container, passes sequentially through a portion of the machine tube, a selectably positionable needle valve, and out the outlet of the nozzle, allowing the user to release the pressurized contents of the container Sprays on selected surfaces and stops spraying activity by releasing the trigger without the need for a separate power source or electric compressor. Another US patent (publication number: US9533818B2) discloses a clamping device for an aerosol canister, said device comprising a housing. The housing includes a gripping portion and a gripping portion for gripping one end of the aerosol canister. The clamping portion includes a peripheral wall and a receiving opening. The circumferential wall defines a space for receiving the dispenser valve of the aerosol canister. The receiving opening communicates with the space. The peripheral wall is further formed with a window communicating with the space, through which the dispenser valve can spray. Another US patent (publication number: US8052015B2) discloses a gripper device. The gripper device includes a handle formed at one end thereof for gripping and a barrel section extending from the other end thereof. The clamping part is formed by the front end of the barrel section opposite to the armrest, and includes two jaws connected together, two limiting grooves respectively formed in the two jaws and extending along the two jaws, opposite to the two jaws respectively. Two inner edge portions of the limiting groove, and two clamping edges respectively formed on the inner walls of the two jaws associated with the two limiting grooves, wherein the clamping edges clamp the neck of the sprayer and support the edge of the sprayer bottom. US patent (publication number: US20080054025A1) discloses a device for fixing and driving a nebulizer. The sprayer includes a neck, a rim formed by the neck, a button valve and a nozzle on the button valve. The device includes a bracket and a trigger, wherein the bracket includes a handle, a barrel extending from the handle, and a clamp extending from the barrel. Additionally, the clamp includes two jaws formed thereon, a mouth defined between the jaws, and a gap defined between the jaws. The neck of the sprayer can be pushed into the mouth through the gap, and the trigger is attached to the bracket so that the trigger can operate the button valve that pushes the sprayer.
