Latching system
First Claim
1. Latching apparatus for releasably latching a first door element, such as a vending machine door, or the like, and a second door element, such as a vending machine frame, or the like, said apparatus comprising:
- a post member defining, at least, a multi-surfaced latching portion, which latching portion includes at least one axially extending notched surface and at least one axially extending smooth surface alternately disposed about the circumference of said post member;
a latching assembly comprising a passage for accepting said latching portion of said post member therein, and a latch means for effecting a grip on said notched surface when said latching portion of said post member is within said passage, thus resisting removal of said latching portion of said post member from said passage of said latching assembly; and
a releasing means for releasing said grip between said notched surface and said latch means, thus facilitating removal of said latching portion of said post member from said passage of said latching assembly.

Abstract
A latching system comprises a notched post assembly, a post gripping assembly and a handle assembly, and, in preferred embodiments, a lock assembly associated with the handle assembly, wherein the notched post assembly is comprised of an elongated post formed at one end with at least two opposing, axially extending rows of notches or teeth and alternately disposed smooth surfaces and the post gripping assembly comprises a channel for accepting the notched end of the post and comprises movable cam elements which cooperate with the notches of the post to effect the primary latching function of the system; and wherein the unlatching of the post from the channel is accomplished by rotating the post to disengage the notches and the cam elements. A pick-resisting improvement to the cylinder lock assembly includes facial piece defined with a plurality of knobs protruding partly into the key entry passage of the lock assembly.

31. Latching apparatus for releasably latching a first door element, such as a vending machine door, or the like, and a second door element, such as a vending machine frame, or the like, said apparatus comprising:
-
a post member supported by one of the door elements, said post member including, at least, a coupling segment and a radial pin which protrudes radially from said coupling segment; a latching assembly supported by the other of the door elements, said latching assembly comprising a passage for accepting at least a portion of said post member therein and means for effecting a grip on said post member when said post member is within said passage, thus resisting removal of said post member from said passage of said latching assembly; a cinch cam means for exerting an axial cinching force on said post member, said cinch cam means comprising a force-receiving cam surface and a force-exerting cam surface; and a handle assembly comprising a releasing means for releasing said grip between said post member and said latching assembly, and primary cylindrical cam means for exerting a primary axial force opposite said cinching force on said cinch cam means, wherein said cinch cam means is constructed to; through said force-receiving cam surface, receive said primary axial force from said primary cylindrical cam means and convert said axial force into a rotational force which effects rotation of said cinch cam means, and through said force-exerting cam surface, convert said rotational force into said axial cinching force and transfer said cinching force to said coupling segment of said post member though said radial pin.

32. Latching apparatus for releasably latching a first door element, such as a vending machine door, or the like, and a second door element, such as a vending machine frame, or the like, said apparatus comprising:
-
a post member defining, at least, a multi-surfaced latching portion, which latching portion includes at least one axially extending notched surface and at least one axially extending smooth surface alternately disposed about the circumference of said post member; a latching assembly comprising a passage for accepting said latching portion of said post member therein, and, at least, one latch element protruding into said passage; and alignment means for changing the relative alignment of said post member and said latching assembly between (i) a latched alignment, while said latching portion is within said passage, wherein said latch element is in alignment with said notched surface, and (ii) an unlatched alignment, while said latching portion is within said passage, wherein said latch element is in alignment with said smooth surface, whereby, in said latched alignment, relative movement of said post member and said latching assembly is prevented in at least one axial direction, and, in said un-latched alignment, relative movement of said post member and said latching assembly in both axial directions is unprevented.
