Hold-Open Latch Assembly for Dispensing Device
First Claim
1. A nozzle system comprising:
- a nozzle body configured to dispense fluid therethrough;
a lever coupled to said nozzle body and movable in a lever plane between a non-operating position and an operating position; and
a latch assembly including;
an engagement surface; and
a cam, wherein said cam is coupled to or positioned on one of said nozzle body or said lever and said engagement surface is coupled to or positioned on the other one of said nozzle body or said lever, wherein the nozzle system is configured such that when said lever is moved from said non-operating position to said operating position, said engagement surface engages said cam to cause at least one of said engagement surface or said cam to move relative to the other such that said lever is automatically retainable in said operating position by said latch assembly, wherein said cam does not pivot about an axis aligned with said lever plane when said lever is moved from one of said non-operating position or said operating position to the other one of said non-operating position or said operating position.

Abstract
A nozzle system including a nozzle body configured to dispense fluid therethrough and a lever coupled to the nozzle body and movable in a lever plane between a non-operating position and an operating position. The nozzle system further includes a latch assembly having an engagement surface and a cam. The cam is coupled to or positioned on one of the nozzle body or the lever, and the engagement surface is coupled to or positioned on the other one of the nozzle body or the lever. The nozzle system is configured such that when the lever is moved from the non-operating position to the operating position, the engagement surface engages the cam to cause at least one of the engagement surface or the cam to move relative to the other such that the lever is automatically retainable in the operating position by the latch assembly. The cam does not pivot about an axis aligned with the lever plane when the lever is moved from one of the non-operating position or the operating position to the other one of the non-operating position or the operating position.

24. A nozzle system comprising:
-
a nozzle body configured to dispense fluid therethrough; a lever coupled to said nozzle body and movable in a lever plane between a non-operating position and an operating position; and a latch assembly configured such that when said lever is moved from said non-operating position to said operating position, said lever is automatically retainable in said operating position by said latch assembly, and wherein said latch assembly is configured such that when said lever is in said operating position and is further actuated, said lever is automatically released to enable said lever to return to said non-operating position, wherein said latch assembly includes; an engagement surface; and a cam including a recessed path configured to receive said engagement surface therein, wherein the latch assembly is configured such that when said lever is moved from said non-operating position to said operating position, said engagement surface engages said cam to cause at least one of said engagement surface or said cam to move relative to the other, wherein said recessed path is generally flat and planar.

25. A nozzle system comprising:
-
a nozzle body configured to dispense fluid therethrough; a lever coupled to said nozzle body and movable in a first direction between a non-operating position and an operating position; and a latch assembly including; an engagement surface coupled to or positioned on said lever; and a cam coupled to or positioned on said nozzle body, said cam including a curved or angled surface and a recess, wherein the nozzle system is configured such that when said lever is moved from said non-operating position to said operating position said engagement surface engages said curved or angled surface of said cam to cause said cam to move relative to the nozzle body, wherein sufficient movement of said lever in said first direction causes said lever to move beyond and no longer contact said curved or angled surface, after which movement of said lever in a second direction opposite to said first direction causes said engagement surface to engage and be retainable in said recess.

26. A method for operating a nozzle system comprising:
-
accessing a nozzle system including a nozzle body configured to dispense fluid therethrough, a lever coupled to said nozzle body and movable between a non-operating position and an operating position, and a latch assembly including an engagement surface and a cam, wherein said cam is coupled to or positioned on one of said nozzle body or said lever and said engagement surface is coupled to or positioned on the other one of said nozzle body or said lever; and moving said lever from said non-operating position to said operating position in a lever plane, which causes said engagement surface to engage said cam to cause at least one of said engagement surface or said cam to move relative to the other such that said latch assembly automatically retains said lever in said operating position, wherein said cam does not pivot about an axis aligned with said lever plane when said lever is moved from said non-operating position to said operating position.
