Safety spray gun trigger

Claim 2

A spray gun trigger disabling apparatus effective on removal of the spray gun spray tip retainer, comprising means for pivoting said trigger about a pivot point for providing a spray gun trigger actuating leverage force; means for moving said pivot point to a position of disabling said spray gun trigger actuating leverage force; a slidable rod connected between said means for moving the pivot point and the spray tip retainer, whereby the removal of the spray tip retainer causes the pivot point to move to the disabling position.

Claim 3

Apparatus as claimed in claim 1 wherein the means for pivoting said trigger further comprises a pin extending between said trigger and said spray gun.

Claim 4

Apparatus as claimed in claim 2 wherein said means for moving said pivot point further comprises a slotted passage in said spray gun and within said pin resides.

Claim 5

Apparatus as claimed in claim 3 wherein said slidable rod extends between said slotted passage and the edge of said spray tip retainer.

Claim 6

Apparatus as claimed in claim 4, wherein the length of said slidable rod is selected to hold said pin in an actuating position when said tip retainer is secured on said spray gun.

Claim 7

A spray gun safety apparatus for diabling the spray gun trigger on removal of the spray tip retainer from the spray gun housing. comprising: a threaded portion on the spray gun for accepting and securing said spray tip and spray tip retainer; a pivot pin contacting said trigger with the spray gun housing; a slotted passage in said spray gun housing for accepting said pivot pin; and a slidable rod extending between said slotted passage and said spray tip retainer to hold said pivot pin in an actuating position when said tip retainer is secured.

Claim 8

A spray gun safety apparatus for diabling the spray gun trigger on removal of the spray tip retainer from the spray gun housing. comprising: a threaded portion on the spray gun for accepting and securing said spray tip and spray tip retainer; a pivot pin contacting said trigger with the spray gun housing; a slotted passage in said spray gun housing for accepting said pivot pin; and a slidable rod extending between said slotted passage and said spray tip retainer to hold said pivot pin in an actuating position when said tip retainer is secured.

Claim 9

Apparatus as claimed in claim 6, further comprising a passage in said gun housing of diameter slightly greater than said slidable rod, said passage extending between said slotted passage and a spray gun surface adjacent the edge of said secured tip retainer, wherein said slidable rod resides.

Claim 10

Apparatus as claimed in claim 7 wherein said pivot pin contacts the trigger near the end of said trigger.

Claim 11

A spray gun trigger disabling apparatus effective on removal of the spray tip and retainer to prevent actuation of the spray gun fluid valve, comprising: a pivot pin passing through the spray gun body and through the trigger; an oversized passage in said spray gun body for passage therethrough of said pivot pin, whereby said pivot pin has freedom of movement therein to at least two positions; a movable member extending between said retainer and said pivot pin, whereby said member holds said pivot pin in a first position when said retainer retains said spray tip and releases said pivot pin to a second position when said retainer is removed.

Claim 12

A spray gun trigger disabling apparatus effective on removal of the spray tip and retainer to prevent actuation of the spray gun fluid valve, comprising: a pivot pin passing through the spray gun body and through the trigger; an oversized passage in said spray gun body for passage therethrough of said pivot pin, whereby said pivot pin has freedom of movement therein to at least two positions; a movable member extending between said retainer and said pivot pin, whereby said member holds said pivot pin in a first position when said retainer retains said spray tip and releases said pivot pin to a second position when said retainer is removed.

Claim 13

The apparatus of claim 9, further comprising a rotatable safety latch means in said spray gun and extending into the path of movement of said trigger, said latch means having a first position restraining trigger movement when said pivot pin is in its first position and having a second position restraining trigger movement when said pivot pin is in a second position.

Claim 14

The apparatus of claim 10, wherein said movable member further comprises a rod slidable within a passage in said spray gun.

Claim 15

Apparatus as claimed in claim 11, wherein said oversized passage in said spray gun body further comprises a slot elongated in the direction of said retainer.
