Abstract
Abstract A latch assembly for use with a stationary member having a drawer opening and a drawer to limit the distance which the drawer may be pulled from the opening, including a curved resilient bifurcated stop for affixing to the stationary member and a ball on the end of a resilient arm for affixing to the drawer, the ball being engageable with the stop to limit outward movement of the drawer and the ball being movable, by bending of the arm, from one side of the stop to the other.

Claim 1
Independent Claim
288 words
A latch assembly for use with a receptacle member having an access opening, a closure member, and means for supporting the closure member for movement along a predetermined path toward and away from said receptacle on the exterior thereof, said latch assembly releasably preventing more than minimum movement of said closure member from a closed position toward a fully opened position, said latch assembly comprising: a stop member and a latch member, said stop member comprising a base portion, and a pair of parallel, spaced-apart arcuate, resilient abutment portions depending from said base portion and extending over an arc of from about 45* to about 90*, the space between said abutment portions being greater at their depending ends than adjacent their point of attachment to the base portion, said latch member comprising a base portion, a resilient arm extending upwardly at an incline from said base portion, and a latching lug with a circular surface on the end of said arm, the diameter of said circular surface being greater than the space between said abutment portions and the width of said arm being less than the space between said abutment portions, and the radius of said circular surface being substantially less than the radius of the arc of the abutment portion whereby upon movement of said closure member toward said receptacle member said circular surface slides on and is cammed downwardly by said abutment portions until it passes the abutment portions, at which point the resiliency of the arm moves it upwardly into the space between the abutment portions, and whereby upon movement of said closure member away from said receptacle member the circular surface engages the arcuate abutment portions to stop such movement of the closure member.
