The invention relates to a supporting element which takes the form of an angle bar. Suitable means are used to provide the bar with a cable guide sheave and the supporting element and the sheave, together with the aforementioned means, are mounted on a guide section of the type used in window regulators. Preferably, a supporting element and a sheave are provided close to each of the ends of the above-mentioned section.

The present invention provides a window operator for a casement window assembly that has secure and moveable linkage of pivoting parts of the operator. The linkage of the moveable operator parts is provided by a rivet having a rivet head with a plurality of fingers or petals extending radially outward of the center of the rivet, and wherein the petals are formed of thickened rivet material. The rivet head is formed in a conical configuration by the force of bending the rivet head with a conical shaped recess in the forming die, thus providing the method of forming the rivet connection in a smooth and progressive force of deforming the rivet head into a domed shape with the thickened petals extending radially outward and downward due to the conical die surface.

An egress 4-bar hinge assembly having two load-bearing links that pivot about spaced-apart bearing pivot points, wherein an entire length of at least one of the links overlies a planar bearing surface. The two links include a cooperating interface selected to engage through only a portion of the respective range of motions. The hinge assembly includes a support extension to define the bearing surface, wherein the support extension can include an integral end cap.

A snap stud usable in window hardware, such as window operators and window hinges, for releasably pivotally interconnecting a pair of members. The snap stud has a stud extending from a first of the members and provided with an external peripheral groove which mounts a C-ring of spring music wire. The C-ring has a retention position partially extending beyond the periphery of the stud for overlying a second of the members and a compressed release position substantially entirely within the periphery of the stud, with the movement of the C-ring to the compressed release position occurring automatically in assembly and disassembly of said members.

A hinge assembly pivotally couples adjacent panels together in an overhead sectional door. The panels include stiles between each lateral end of the panel to which the hinge assemblies are attached. The hinge assembly includes an upper hinge leaf on an upper panel with a pair of spaced generally parallel flanges which span the juncture between the upper and lower panels. The hinge assembly also includes a lower hinge leaf with a pair of flanges projecting generally parallel to each other. The lower hinge leaf is mounted to one of the stiles of the lower panel and each flange includes a pivot axis hole near a terminal end thereof for alignment with a pivot axis hole in one of the flanges of the upper leaf. The stile includes a pair of spaced, parallel sidewalls and a notch, depression or recess is on each sidewall. The recesses provide a seat for the respective flanges of the hinge leaves and clearance between the sidewall of the stile and any adjacent components. A rivet or similar pivotal connector device is seated within the pivot axis holes on each side of the hinge.

A rail bracket is attached to a window rail with a rivet. The rivet has a non-circular shape, such as an oval shape, which cooperates with an opening in the rail bracket to prevent the rail bracket from rotating relative to the window rail during riveting.

A stud (1) for mounting a pulley (2) to a plate (3) by a cold forming process has a large diameter head (5), a cylindrical shank (6) which acts as the stub shaft for the pulley (2), the end of the shank remote from the head being connected to a smaller diameter shank (7) via a shoulder (9) (which may include an annual grove (10) into which the plate (3) is deformed), and, beyond the smaller diameter shank, an e.g. threaded shaft (8). To resist rotation after the stud (1) is cold formed to the plate (3), the stud (1) has ribs or studs or flat facets on the shoulder or on the narrow shank (7) against which the plate is cold formed.

An apparatus is disclosed for correcting misalignment problems in a casement window. An adjustment stud is included in an improved casement window unit. The adjustment stud includes a tenon mounted on a track assembly and a post to which a sash arm is rotatably attached. The tenon and post are eccentric with respect to one another. When alignment problems occur the central axis of the post may be rotated about the central axis of the tenon to a desired orientation such that the alignment problem is corrected.
摘要:
A connection for adjustably holding two window hardware members in pivotally connected relationship, including a first hardware member with a first cylindrical opening, a second hardware member with a second cylindrical opening, and a stud. The stud has a flange having two substantially parallel faces and a peripheral surface therebetween, with a rivet portion projecting from one face and a pivot portion projecting from the other face. The rivet portion includes a cylindrical neck extending through the first cylindrical opening and a head on the end of the neck, the flange and the head engaging opposite sides of the first hardware member to frictionally secure the stud against freely pivoting relative to the track. The pivot portion includes a cylindrical shaft eccentric from the cylindrical neck and extending through the second cylindrical opening. A C-ring is disposed in an external peripheral groove in the pivot portion to secure the second hardware member thereto for pivoting about the cylindrical shaft. A part of the C-ring is in the peripheral groove and a part extends radially beyond the pivot portion periphery when the C-ring is in a securing position. The peripheral groove has a depth to enable deformation of the C-ring by movement of the spaced-apart ends towards each other to a release position in which substantially all of the C-ring is in the peripheral groove. The stud flange peripheral surface is engageable with a tool to allow for adjustment of the pivotal connection by pivoting the stud.
