Claims15
A latch assembly comprising a base, a knob movably mounted on the base for movement between a latched position and an unlatched position, a latch pivotally mounted between the base and the knob, the base including a fulcrum which engages the latch and about which the latch is pivotable, the latch having a generally V-shaped fulcrum portion which includes a trough portion which engages said fulcrum and a pair of cam-engaging portions which diverge from the trough portion, and cam means on the knob engageable with the latch for pivoting the latch into a latched position when the knob moves to its latched position and for pivoting the latch into an unlatched position when the knob moves to its unlatched position, said cam means including a first cam which is engageable with one of said cam-engaging portions of the latch when the knob moves to its latched position and a second cam which is engageable when the other of said cam-engaging portions of the latch when the knob moves to its unlatch position.
A latch assembly comprising a base, a knob slidably mounted on the base for sliding movement between a latched position and an unlatched position, the knob having an elongated slot which extends in the direction of sliding movement, a latch pivotally mounted between the base and the knob, the base including a fulcrum which engages the latch and about which the latch is pivotable, and cam means on the knob engageable with the latch for pivoting the latch into a latched position when the knob moves to its latched position and for pivoting the latch into an unlatched position when the knob moves to its unlatched position, the latch and the base being providing with openings which are aligned with the elongated slot in the knob, and fastener means extending through the slot and the aligned openings for holding the knob, latch and base together.
A latch assembly comprising a base, a knob movably mounted on the base for movement between a latched position and an unlatched position, a latch pivotally mounted between the base and the knob, the base including a fulcrum which engages the latch and about which the latch is pivotable, and cam means on the knob engageable with the latch for pivoting the latch into a latched position when the knob moves to its latched position and for pivoting the latch into an unlatched position when the knob moves to its unlatched position, the latch including a flexible latching portion which can be flexed out of its latched position when the cam means engages the latch in the latched position.
A latch assembly comprising a base, a knob slidably mounted on the base for movement between a latched position and an unlatched position, a latch pivotally mounted between the base and the knob for pivoting movement about an axis which extends parallel to the direction of sliding movement of the knob, the base including a fulcrum which engages the latch and about which the latch is pivotable, and a pair of cam surfaces on the knob which are spaced apart on opposite sides of said pivot axis and which extend generally parallel to said pivot axis, one of the cam surfaces being engageable with the latch when the knob slides to its latched position for pivoting the latch about said pivot axis to its latched position and the other cam surface being engageable with the latch when the knob slides to its unlatched position for pivoting the latch about said pivot axis to its unlatched position.
A latch assembly for a picnic cooler having a chest and a cover hingedly attached to the chest, the latch assembly comprising a base secured to the cover, a knob movably mounted on the base for movement between a latched position and an unlatched position, a latch pivotally mounted between the base and the knob and including a pivot portion, a hook portion, and an intermediate portion connecting the hook portion and the pivot portion, the base including a fulcrum which engages the pivot portion of the latch and about which the latch is pivotable, and cam means on the knob engageable with the pivot portion of the latch for pivoting the latch into a latched position in which the hook portion is positioned in a recess in the chest when the knob moves to its latched position and for pivoting the latch into an unlatched position in which the hook portion is out of the recess in the chest when the knob moves to its unlatched position.
A latch assembly comprising a base, a knob movably mounted on the base for movement between a latched position and an unlatched position, a latch pivotally mounted between the base and the knob, the base including a fulcrum which engages the latch and about which the latch is pivotable, and cam means on the knob engageable with the latch for pivoting the latch into a latched position when the knob moves to its latched position and for pivoting the latch into an unlatched position when the knob moves to its unlatched position, said knob being mounted on the base for sliding movement between its latched position and its unlatched position, the knob being slidable in a direction generally parallel to the axis about which the latch pivots, said cam means including a pair of cam surfaces on the knob which are spaced apart on opposite sides of said pivot axis and which extend generally parallel to said pivot axis, one of the cam surfaces being engageable with the latch when the knob slides to its latched position for pivoting the latch about said pivot axis to its latched position and the other cam surface being engageable with the latch when the knob slides to its unlatched position for pivoting the latch about said pivot axis to its unlatched position in which the latch includes a pivot portion engaging said fulcrum, a hook portion adapted to be received in a latching recess when the latch is in its latched position, and an intermediate portion connecting the hook portion and the pivot portion, the intermediate portion being flexible to permit the hook to be forced out of the recess when the latch is in its latched position.
