Embodiments of the present invention relate to a window actuator linkage assembly having barrel brackets, a mounting bracket, and a clamping plate and, more particularly, to a window actuator linkage assembly on a moveable portion of the window that facilitates adjustment of the alignment of a chain extending from a fixed portion of the window to the moveable portion of the window.
As referred to in this document, a window is an opening constructed in a wall, door, or roof for the purpose of admitting light or air to a space within a building enclosure and is framed and spanned with glass mounted to permit opening and closing.
Windows in buildings can be installed with motorized actuators for convenience of opening and closing the moveable portion of the window, without having physical human contact with the window. The actuator can be mounted on an exposed fixed surface of a window frame or mounted unexposed and recessed into the fixed frame part of the window. The actuator utilizes a conventional push-pull chain or similar chain (hereinafter “chain” or “actuator chain”), such as described in U.S. Pat. No. 8,250,846, that can bend in one direction only and thus allows the chain to push a load, and to thus open and close the moveable portion of the window. U.S. Pat. No. 8,250,846 is incorporated herein by reference in its entirety.
One end of the chain is connected to a window chain linkage on the moveable portion of the window, and the other end of the chain is connected to an actuator chain linkage of the actuator. The chain is driven by an actuator motor, which causes the chain to extend from the actuator and retract into the actuator, to thereby respectively open and close the window.
Difficulties can arise in obtaining proper mounting alignment between the actuator chain linkage—when the actuator is either mounted on or recessed into the fixed portion of the window—and the window chain linkage, particularly when the actuator is mounted unexposed and recessed into the fixed frame part of a window. Even relatively small misalignments between the ends of the chain proximate the actuator chain linkage and the window chain linkage can cause binding of the actuator chain such that moveable portion of the window may not close properly.
Misalignments can be caused by conditions such as imprecise surface mounting of the actuator, imprecise machining of the concealed recess within the window frame, slightly out of square moveable portions of the window, slightly out of plumb or level window frame installation, and/or window component movement caused by thermal expansion and contraction. The relatively small tolerances required for proper operation make issues caused by slight misalignment common.
When the moveable portion of the window does not close properly and contact the window seals, water, air and noise intrusion can occur, and security can be compromised. Attempts to resolve misalignment between the actuator chain linkage and the window chain linkage, such as by remounting the actuator or attempting in-place machining of the actuator linkage on the moveable portion of the window, can be time consuming and costly, and may not effectively correct the misalignment.
Misalignment between the window chain linkage and the actuator chain linkage can be further complicated when, for example, large windows utilize multiple actuators. Under such circumstances, one actuator may not pull the window closed fully while the other actuator does, thereby causing a potentially dangerous out-of-plane bending force to be applied to the moveable portion of the window that could potentially cause the glass to break, especially in the presence of thermal stresses due to indoor to outdoor temperature differences.

A conventional window actuator 1104 (such as the KIMO 202 model by Nekos SRL, Colceresa (VI), Italy) having a conventional push-pull actuator chain 104, can be used to open and close the movable portion 1101 of window 1106, without having direct physical human contact with the window. The actuator chain 104 includes, for example, inner plates 104a, 104b, outer plates 104c, 104d, window chain linkage 104e, pinhole 104f, and pins 104g, 104h, which are conventional and part of the KIMO 202 actuator.
Barrel brackets 101a, 101b are separated by a space into which the window chain linkage 104e is positioned. When window chain linkage 104e is positioned between the barrel brackets 101a, 101b, the window chain linkage 104e and barrel brackets 101a, 101b are kept in alignment by a fastener 105, such as a screw or pin, that is inserted through the respective openings, such as a conventional bore hole, of the first barrel bracket 101a, the window chain linkage 104e, and the second barrel bracket 101b, such as in an analogous manner to the two leaves of a door hinge and the hinge pin that holds them together. Barrel brackets 101a, 101b respectively include screw holes 107a, 107b. Fasteners, such as screws 109a, 109b, are inserted through screw holes 107a, 107b to respectively fasten barrel brackets 101a, 101b to desired locations along the length of bracket 106, as explained further herein. Screws 110a, 110b are respectively inserted into screw holes 108a, 108b and tightened to secure the actuator linkage assembly 100 to a moveable portion 1101 of window 1106, as shown, for example, in
In an embodiment, the bracket 106 has two oblong slotted holes 202a, 202b, which can be equidistant from a midpoint along the length of the bracket 106. Generally, slotted holes 202a, 202b will have a smaller transverse width than the corresponding transverse width of slotted holes 201a, 201b, because slotted holes 202a, 202b can be sized to accommodate the diameter of screws 108a, 108b, whereas slotted holes 201a, 201b are sized to accommodate the relatively larger transverse width of bracket extensions 101c, 101d that are used with barrel bracket extensions 101c, 101d.
In
When barrel bracket extensions 101c, 101d are utilized, screw 109a is inserted through screw hole 107a, which extends through barrel bracket 101a and barrel bracket extension 101c, and is threaded into threaded screw hole 302a of clamping plate 301. Similarly, screw 109b is inserted through screw hole 107b, which extends through barrel bracket 101b and barrel bracket extension 101d, and is threaded into threaded screw hole 302b of clamping plate 301. Screw holes 107a, 107b are preferably unthreaded.

The actuator linkage assembly 1600 includes elements such as barrel brackets 1601a, 1601b that have openings 1603a, 1603b (shown in
A conventional window actuator 1104 (such as the KIMO 202 model by Nekos SRL, Colceresa (VI), Italy) having a conventional push-pull actuator chain 104, can be used to open and close the movable portion 1101 of window 1106, without having direct physical human contact with the window. The actuator chain 104 includes, for example, inner plates 104a, 104b, outer plates 104c, 104d, window chain linkage 104e, pinhole 104f, and pins 104g, 104h, which are conventional and part of the KIMO 202 actuator.
T-shaped base 1602 respectively includes screw holes 1607a, 1607b. Fasteners, such as screws 1609a, 1609b, are inserted through screw holes 1607a, 1607b to respectively fasten barrel brackets 1601a, 1601b in a desired position along the length of slotted base bracket 1606, as explained further herein. In addition, screws 1610a, 1610b are respectively inserted into screw holes 1608a, 1608b and tightened to secure the actuator linkage assembly 1600 to a moveable portion 1101 of window 1106, as shown, for example, in
The barrel brackets 1601a, 1601b may be in the form of an elongate extrusion (for example, of aluminium or another suitable metal) which can be cut to a suitable length. In such an embodiment, the barrel brackets 1601a, 1601b may be formed as an integrally formed element, but it should be appreciated that variations, such as barrel brackets 1601a, 1601b which are formed from two or more parts, are within the scope of the present disclosure.
When window chain linkage 104e is positioned between the barrel brackets 1601a, 1601b, in opening 1702, the window chain linkage 104e and barrel brackets 1601a, 1601b are kept in alignment by fastener 105, which is inserted through a respective openings 1603a, 1603b, such as a conventional bore hole, of the first and second barrel brackets 1601a, 1601b, and an opening of the window chain linkage 104e, as shown in
The slotted base bracket 1606 has a first transverse side 1650a and a second transverse side 1650b, and an inner surface 1658a and an outer surface 1658b. The first transverse side 1650a includes a first wall 1652a that projects substantially perpendicularly away from the inner surface 1658a. The first wall 1652a terminates, along its edge distal from the inner surface 1658a, in a first return portion 1654a which extends away from first wall 1652a substantially towards the second transverse side 1650b of the slotted base bracket 1606.
The first wall 1652a and first return portion 1654a provide the first connection portion 1656a, which together define the first connection slot 1660a. The first connection slot 1660a is thus elongate and bounded in three of its transverse directions (e.g. left, top and bottom as seen in
Similarly, the second transverse side 1650b includes a second wall 1652b that projects substantially perpendicularly away from the inner surface 1658a. The second wall 1652b terminates, along its edge distal from the inner surface 1658a, in a second return portion 1654b which extends away from second wall 1652b substantially towards the first transverse side 1650a of the slotted base bracket 1606.
The second wall 1652b and second return portion 1654b provide the second connection portion 1656b, which together define the second connection slot 1660b. The second connection slot 1660b is thus elongate and bounded in three of its transverse directions (e.g. right, top and bottom as seen in
Thus, it will be appreciated that in this embodiment, the shapes of the first and second transverse sides 1650a, 1650b, are similar and generally symmetrical to each other, and spaced apart in the transverse width direction of the slotted base bracket 1606. The respective first and second connection slots 1660a, 1660b are also similar to each other and spaced apart in the transverse width direction of the slotted base bracket 1606.
