Abstract
Abstract A latch mechanism is mounted on a door or panel hingedly mounted on the frame of a construction vehicle or the like. The latch mechanism comprises a handle pivotally mounted in exposed relationship on an upper side of the door for movement between latched and unlatched positions thereon. A guide block is secured to an underside of the door and a latch member is slidably mounted in the guide block. The latch member is connected to the handle for sliding movements between a latched position underlying a stationary panel of the vehicle and an unlatched position whereby the door may be opened in response to raising of the handle. Detent means are provided between the guide block and the latch member to hold the member in its unlatched position when the door is open. A key lock may be mounted on the door to selectively hold the latch member plate in its latched position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
176 words
A latch mechanism mounted on a first member movably mounted on a second member comprising handle means movably mounted on an outer side of said first member for movement between latched and unlatched positions thereon, guide means secured to an underside of said first member, and a latch member comprising a resilient spring-like member slidably mounted on said guide means and connected to said handle for sliding movements between said latched position underlying an inner side of said second member and said unlatched position in response to movement of said handle means, said latch member including a bent spring portion formed unitarily therewith to function as a spring for biasing said latch member against said inner side of said second member when the latch member is in said latched position, said spring-like latch member further including a detent portion formed unitarily thereon, said guide means including a recess defined therein positioned to accommodate said detent portion, said detent portion resiliently deflecting into said recess to thereby releasably hold said latch member in said unlatched position thereof.
Claim 2
Dependent Claim
