Frictionless cabinet latch

Claim 2

A flush mounted cabinet latching mechanism with recessed handle for actuating a sliding bolt latch the end of which has an anti-friction rocker arm for actuating the sliding bolt upon contact with a striker, the mechanism comprising: a. a yoke shaped sliding bolt, b. a spring urging the open ended arms of the yoke shaped sliding bolt outward, c. a recessed handle pivotally mounted and having an offset lever arm extending into, and in contact with, the base of, the slot between the open ended arms, such that movement of the lever arm moves the sliding bolt against the spring, d. a pivot pin located near the end of and extending between the open ended arms, and e. a rocker arm slotted to accept the pin extending between the open ended arms, and rotatably pinned to the support structure.

Claim 3

A flush mounted cabinet latching mechanism as recited in claim 1, wherein: the rocker arm extends beyond the open ended arms of the sliding bolt to become a latch member.

Claim 4

A flush mounted cabinet latching mechanism as recited in claim 2, wherein the sliding bolt is rotated 180 degrees and the pin for pivoting the rocker arm is mounted to the support structure at a point to retain the relationship between the sliding bolt and the rocker arm.

Claim 5

A flush mounted latching mechanism for passenger transport aircraft interior doors comprising: a. a slideably mounted yoke shaped latch bolt; b. a yoke pin between the double armed end of the yoke and extending through a slot in, c. a rocker arm rotatably pinned to the latch mechanism structure such that contact of the rocker arm against a striker causes rotation of the rocker arm to act against the yoke pin to slide the latch bolt, d. a recessed handle, having an offset lever arm in contact with the base of the yoke, and being pivotally mounted such that rotation of the handle acts through the offset lever arm to slide the latch bolt to disengage the latch, and e. a spring resiliently urging the latch bolt into engagement.

Claim 6

A flush mounted latching mechanism for passenger transport aircraft interior doors comprising: a. a slideably mounted yoke shaped latch bolt; b. a yoke pin between the double armed end of the yoke and extending through a slot in, c. a rocker arm rotatably pinned to the latch mechanism structure such that contact of the rocker arm against a striker causes rotation of the rocker arm to act against the yoke pin to slide the latch bolt, d. a recessed handle, having an offset lever arm in contact with the base of the yoke, and being pivotally mounted such that rotation of the handle acts through the offset lever arm to slide the latch bolt to disengage the latch, and e. a spring resiliently urging the latch bolt into engagement.

Claim 7

A flush mounted latching mechanism for passenger transport aircraft interior doors as recited in claim 4, wherein: the rocker arm Extends beyond the latch bolt to become the latching means in combination with the striker.

Claim 8

A flush mounted latching mechanism for passenger transport interior doors as recited in claim 5, wherein: the attach point, on the latching mechanism structure, of the pivoting pin for the rocker arm is relocated on the opposite side of the latch bolt and the latch bolt is turned over to provide latching from the opposite direction.

Claim 9

A flush latching mechanism for passenger transport aircraft interior doors with recessed handle for actuating a sliding bolt latch the end of which has an anti-friction rocker arm for actuating the sliding bolt upon contact with a striker, the mechanism comprising: a. a yoke shaped sliding bolt, b. a spring urging the open ended arms of the yoke shaped sliding bolt outward, c. a recessed handle pivotally mounted and having an offset lever arm extending into, and in contact with, the base of, the slot between the open ended arms, such that movement of the lever arm moves the sliding bolt against the spring, d. a pivot pin located near the end of and extending between the open ended arms, and e. a rocker arm slotted to accept the pin extending between the open ended arms, and rotatably pinned to the support structure, such that contact of the rocker arm with a striker imparts rectilinear movement to the sliding bolt latch to first clear then engage the striker due to reciprocal movement imparted by the spring.

Claim 10

A flush latching mechanism for passenger transport aircraft interior doors with recessed handle for actuating a sliding bolt latch the end of which has an anti-friction rocker arm for actuating the sliding bolt upon contact with a striker, the mechanism comprising: a. a yoke shaped sliding bolt, b. a spring urging the open ended arms of the yoke shaped sliding bolt outward, c. a recessed handle pivotally mounted and having an offset lever arm extending into, and in contact with, the base of, the slot between the open ended arms, such that movement of the lever arm moves the sliding bolt against the spring, d. a pivot pin located near the end of and extending between the open ended arms, and e. a rocker arm slotted to accept the pin extending between the open ended arms, and rotatably pinned to the support structure, such that contact of the rocker arm with a striker imparts rectilinear movement to the sliding bolt latch to first clear then engage the striker due to reciprocal movement imparted by the spring.
