Abstract
Abstract A control arm assembly for hinged members, and including a pair of arms pivotally connected together and with the free ends of the arms being attachable to a hinged member and an anchor point, and with the arms limiting the extent of pivot of the hinged member. The arms serve as either left-hand or right-hand assembly, depending upon arrangement of parts, and one of the arms includes an arcuate slot and the other of the arms has two spaced-apart openings for alternately receiving a bolt which also goes through the slot, and, depending upon which of the two holes the bolt is received in, the arms are either left-hand or righthand in assembly. The arms may also be fastened together, by means of a threaded knob, so that they can be retained in a selected pivoted position to hold the hinged member in a certain pivoted position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A control arm assembly for hinged members, comprising a pair of arms pivotally connected together at the ends thereof and extending into free ends for pivotally connecting to a hinged member to be controlled in hinged position, one of said arms having an arcuate slot therein spaced from and centered with the pivot axis, the other of said arms having two openings aligned with said slot and being on opposite sides of the pivot axis of said arms for alternately receiving said fastener and thereby alternately forming a left-hand and a right-hand assembly, and a fastener extending through said arcuate slot and a selected one of said openings for releasably tightening said arms together and thereby releasably secure said arms in a set pivoted position.
Claim 2
Dependent Claim
125 words
A control arm assembly for hinged members, comprising a pair of arms pivotally connected together at the ends thereof and extending into free ends for pivotally connecting to a hinged member to be controlled in hinged position, one of said arms having an arcuate slot therein spaced from and centered with the pivot axis, the other of said arms having two openings aligned with said slot and being on opposite sides of the pivot axis of said arms for alternately receiving said fastener and thereby alternately forming a left-hand and a right-hand assembly, and a fastener extending through said arcuate slot and a selected one of said openings for releasably tightening said arms together and thereby releasably secure said arms in a set pivoted position.
Claim 3
Dependent Claim
27 words
The control arm assembly as claimed in claim 1, wherein said fastener includes a knob for hand gripping in tightening and loosening said fastener on said arms.
Claim 4
Dependent Claim
