Abstract
Abstract A latch arrangement for latching one furniture component to another in side-by-side abutting relationship includes a horizontal crank arm attached to the underside of one component and a hook attached to the underside of the other component in a position to be engaged by the crank portion of the crank arm or by a link pivotally carried by the crank arm. In operation the crank arm is rotated about its axis, by means of a removable handle, first in one direction to extend the crank portion of the arm laterally of its respective furniture component so as to be engageable with the hook and then in the opposite direction to draw the components together. Both the hook and the crank portion of the crank arm are arranged to lie wholly underneath their respective furniture components when not in use, so as to be concealed from view. In the construction in which the crank portion directly engages the hook, the latter is arranged to move in a vertical plane to accommodate the vertical component of movement of the crank portion of the crank arm during rotation of the crank arm toward its latching position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A latch arrangement for latching one furniture component to another in adjacent abutting relationship comprising: a horizontal crank arm rotatable about its axis carried on the underside of one furniture component, said arm having a crank portion projecting outwardly from the rotation axis and said arm being located such that in a first rotational position of the arm the crank portion lies wholly underneath its respective furniture component and in a second rotational position of the arm the crank portion lies laterally of its respective furniture component; and an engageable hook carried by the underside of the other furniture component, means mounting said hook on said other furniture component for movement between a position concealed below said component and another position projecting laterally of said other furniture component, the arrangement being such that in moving from its second position to its first position said crank portion swings first downwardly and then upwardly thereby being capable of applying a pulling force to said hook.
Claim 2
Dependent Claim
163 words
A latch arrangement for latching one furniture component to another in adjacent abutting relationship comprising: a horizontal crank arm rotatable about its axis carried on the underside of one furniture component, said arm having a crank portion projecting outwardly from the rotation axis and said arm being located such that in a first rotational position of the arm the crank portion lies wholly underneath its respective furniture component and in a second rotational position of the arm the crank portion lies laterally of its respective furniture component; and an engageable hook carried by the underside of the other furniture component, means mounting said hook on said other furniture component for movement between a position concealed below said component and another position projecting laterally of said other furniture component, the arrangement being such that in moving from its second position to its first position said crank portion swings first downwardly and then upwardly thereby being capable of applying a pulling force to said hook.
Claim 3
Dependent Claim
54 words
A latch arrangement as in claim 1 wherein said crank portion is arranged to directly engage said hook in swinging from its second position toward its first position, said arrangement including means mounting said hook for movement in a vertical plane to accommodate the vertical component of the swinging movement of said crank portion.
Claim 4
Dependent Claim
31 words
A latch arrangement as in claim 1 including an intermediate swingable link between said hook and said crank portion for accommodating the vertical component of swinging movement of said crank portion.
Claim 5
Dependent Claim
30 words
A latch arrangement as in claim 3 wherein said link is a U-shaped link having legs pivoted to said crank portion and having a body directly engageable with said hook.
Claim 6
Dependent Claim
24 words
A latch arrangement as in claim 1 wherein the position of said hook is adjustable in a horizontal plane to permit plural extended positions.
Claim 7
Dependent Claim
28 words
A latch arrangement as in claim 1 wherein said mounting means for said hook permits swinging movement of said hook between its concealed position and its projecting position.
