Abstract
Abstract The top of the panel in a window or door of the turn-and-tilt type is secured to the associated frame by a pivot assembly having a vertical axis and attached to the frame and by an arm whose one end portion is conformingly received in a connector on the pivot assembly. The connector is a channel whose flanges slope obliquely toward each other from the web so as to permit sliding longitudinal movement of the arm, but to prevent transverse movement of the arm out of the channel. Cooperating, partly adjustable abutments limit the longitudinal movement of the arm relative to the connector. The free end of the arm is movably attached to the panel top.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
A stay arrangement for a window or door panel pivotally movable relative to an associated frame comprising: a. a pivot assembly having a stationary part adapted to be attached to said frame, and a movable part connected to said stationary part for relative movement about an axis; b. a connector member fixedly attached to said movable part and elongated radially relative to said axis, said connector member being channel-shaped and having a web portion and two flange portions sloping away from said web portion at respective acute angles and toward each other; c. an elongated arm member, one longitudinally terminal portion of said arm member being received in said connector member in conforming, longitudinally slidable engagement with said web and flange portions; d. securing means for securing the other longitudinally terminal portion of said arm member to said panel; and e. limiting means for limiting relative longitudinal movement of said arm member in said connector member.
Claim 2
Dependent Claim
156 words
A stay arrangement for a window or door panel pivotally movable relative to an associated frame comprising: a. a pivot assembly having a stationary part adapted to be attached to said frame, and a movable part connected to said stationary part for relative movement about an axis; b. a connector member fixedly attached to said movable part and elongated radially relative to said axis, said connector member being channel-shaped and having a web portion and two flange portions sloping away from said web portion at respective acute angles and toward each other; c. an elongated arm member, one longitudinally terminal portion of said arm member being received in said connector member in conforming, longitudinally slidable engagement with said web and flange portions; d. securing means for securing the other longitudinally terminal portion of said arm member to said panel; and e. limiting means for limiting relative longitudinal movement of said arm member in said connector member.
Claim 3
Dependent Claim
56 words
An arrangement as set forth in claim 1, wherein said arm member is a flat bar having top and bottom faces and lateral edge faces narrower than said top and bottom faces, said edge faces being beveled for conforming engagement with said flange portions, each edge face being formed with at least one laterally open notch.
Claim 4
Dependent Claim
16 words
said securing means securing said other longitudinally terminal portion of said arm member to said panel.
Claim 5
Dependent Claim
16 words
said securing means securing said other longitudinally terminal portion of said arm member to said panel.
Claim 6
Dependent Claim
16 words
An arrangement as set forth in claim 2, wherein said notch tapers in a lateral direction.
Claim 7
Dependent Claim
136 words
An arrangement as set forth in claim 1, wherein one of said members is formed with a bore therethrough, and the other member is formed with a recess therein, said bore and said recess communicating in all operative positions of said pivot assembly, said limiting means including a pin element having an axis and received in said bore for pivotal movement about said axis thereof, and an enlarged head element fixedly fastened to one axial end of said pin element, said head element being received in said recess and dimensioned for angular movement in said recess during said pivotal movement, an orthogonal projection of said head element in a plane radial relative to the axis of the pin element having a geometrical center, and said axis of the pin element being radially spaced from said center.
Claim 8
Dependent Claim
20 words
An arrangement as set forth in claim 4, wherein said projection has the shape of a quadrangle having rounded corners.
Claim 9
Dependent Claim
33 words
An arrangement as set forth in claim 4, wherein said head element includes tool engaging means engageable by a tool for rotation of said plate element about the axis of said pin element.
Claim 10
Dependent Claim
16 words
An arrangement as set forth in claim 4, wherein said one member is said arm member.
Claim 11
Dependent Claim
46 words
An arrangement as set forth in claim 4, wherein said limiting means further include a lug on said connector member, said arm member being formed with a recess, said lug being received in said recess with clearance in the direction of elongation of said arm member.
Claim 12
Dependent Claim
37 words
A window or door comprising, in combination: a. a frame member defining one side of an opening b. a panel dimensioned for being received in said opening; and c. the stay arrangement set forth in claim 1,
