Description

Brace hinge assemblies and window assemblies for windows

technical field

This invention relates to stay hinge assemblies for doors and windows. In particular, the present invention relates to, but is not limited to, four-bar sliding stay hinge assemblies and/or six-bar sliding stay hinge assemblies for windows.

Background technique

Windows typically include one or more movable sashes and sashes that are mounted into openings in the wall. A variety of different hinges for windows are known, depending on the particular size and strength required. One such hinge is known as a slider, and may be, for example, a four-bar slider, also known as a four-bar bracket. In a stay, the window is supported on a sash plate which is connected by a plurality of support arms to a frame plate to which the frame plate is mounted. In a four-bar hinge, the sash and frame panels are connected by three support arms that pivot at their junctions. One of the support arms is slidably connected to the frame panel to allow opening and closing of the window.

Therefore, in order to properly operate a stay hinge assembly and/or not place undue stress on the components of the hinge assembly, each component of the stay hinge assembly must be specifically and accurately manufactured with respect to the other components to properly operate the stay hinge assembly. support. This is time consuming and cost prohibitive.

Further, in known sliding stays, the movement of the elements of the bracket may break off the tip of the sash panel or come into contact with a plug on the sash panel. This effect may occur and/or be exacerbated over time depending on wear of the components or due to other events that cause the struts to misalign. It is desirable to have a stay where the tip moves through the plug before moving outward from the window frame.

Contents of the invention

For reliable and consistent opening and closing of windows, it is important that the geometry of the hinge assembly be accurate and precise. The geometry of a brace hinge assembly is said to be fixed when the fixed spacing between the joint points of the hinge assembly remains the same. The two geometries of the brace hinge assemblies are considered to be different if at least one fixed distance between the connection points of the two hinge assemblies differs.

As used herein, the term "fixed spacing" between connecting members of a brace includes maintaining the same distance between connection points in a consistent brace hinge assembly during opening and closing operations. In the context of the present invention, the term "fixed spacing" may only be used as a designation, as in aspects of the invention, one or more of the "fixed spacings" may actually vary. The fixed spacing may be measured along the length of one of the support arm, frame panel or sash panel.

The geometry of the stay hinge assemblies can thus be defined by the fixed spacing of said stay hinge assemblies. The geometry of the stay hinge assembly need not constrain the relative angles between the frame panels, sash panels and/or support arms at any given point during the opening/closing of the hinge assembly, as those differ depending on the hinge assembly. The relative angle of the position. Rather, the geometry of the hinge assembly may be determined by the fixed spacing and length of the frame panels, sash panels and/or support arms as they define the opening and closing of the sash panels at the hinge assembly. process itinerary.

The inventors understand that by varying the length of one or more support arms (or linkages) of a sliding stay, the travel of these support arms during opening and closing of the window can be varied. In particular, if the hinged support arms of the braces increase in length, the travel of the tip of the sash plate is changed so that it has a greater clearance of the plug of the sash plate before moving outwards from the window frame. However, by changing the length of one or more of the support arms, for example by increasing the length of the hinge support arms, the geometry of the stay assembly is changed such that the stay hinge assembly is inoperable. This is because one of the fixed spacings of the brace hinge assembly has been changed and the remaining elements of the brace hinge assembly cannot accommodate the new geometry.

During an opening operation of the hinge assembly, the spacing changing means is movable from the first position to the second position. This movement may have been biased. Movement between the first and second positions of the spacing changing means may be caused by an initial movement of the hinge assembly from the closed position to the open position. Alternatively, the movement between the first geometric shape and the second geometric shape may take place during a later stage of the opening operation of the hinge assembly.

Illustrative embodiments of the present invention will be described herein with reference to the accompanying drawings. In the attached picture:

Fig. 1 is the plane view of four-bar sliding stay hinge assembly;

Figure 2 is a perspective view of a portion of the stay hinge assembly;

Detailed ways

FIG. 1 shows a four-bar hinge assembly 1 . Assembly 1 includes sash plate (or fourth link) 2, window frame plate (or track) 4, and three support arms: hinge support arm (or first link) 6, main support arm (or third link) ) 8, and a bridging support arm (or a second link) 10, wherein the bridging support arm 10 extends between the main support arm 8 and the window frame panel 4. The sash panel 2 has a tip 12 configured to be received in a plug 14 of the sash panel 4 during operation of the closing hinge assembly 1 .

The sash end of the hinge support arm 6 is pivotally connected to the sash panel 2 by a connection 16 towards the tip 12 of the sash panel 2 . At the sash end, the hinge support arm 6 is pivotally connected to the sash panel 4 by means of a connection 18 .

The bridging support arm 10 is pivotally connected to the main support arm 8 by a link 20 and to the sash panel 4 by a link 22 .

Ahead of the point at which link 16 of hinge support arm 6 connects to sash panel 2 (ie further away from plug 14 and closer to the front edge of assembly 1 ), the sash end of main support arm 8 is pivotally connected by link 24 to sash panel 2. The sash end of the main support arm 8 is pivotally connected to the sash panel 4 by a link 26 ahead of where the connection 18 of the hinge support arm 6 and the connection 22 of the bridging support arm 10 are connected to the sash panel 4 .

In an exemplary glide stay, the connection 26 of the main support arm 8 to the window frame panel 4 or the connections 18, 22 of the bridge support arm 10 and the hinge support arm 6 to the window frame panel 4 can slide. However, only the spacing between link 26 and links 22 and 18 (if they move, they move together) can vary and may be referred to as variable spacing. All other spacings between the connectors are fixed spacings, which are called fixed spacings because they do not change during opening and closing of the door or window.

In use, a pair of hinge assemblies, comprising hinge assembly 1 and a mirrored hinge assembly, are mounted to opposite sides of a window or door. The sash plate 2 of the hinge assembly may be attached to the top and bottom edges of the sash (or the sides when used in a top-hung or awning window) while the sash plate 4 is attached to the corresponding edge of the sash .

When the sash is opened, the front edge end 18 of the sash panel 2 is pushed outwards due to the outward (relative to the building) force exerted by the user on the sash. In the exemplary arrangement of FIG. 1 , the main support arm 8 is only pivotally movable relative to the sash panel 4 and cannot slide along the sash panel 4 . Thus, the slider 28 is pulled along the sash panel 4 towards the pivot connection 26 where the main support arm 8 is connected to the sash panel 4 . The sash panel 2 swings outwards (clockwise in FIG. 1 ) the sash panel 4 . Movement of the slider 28 causes the tip 12 to separate from the plug 14.

It will be appreciated that other arrangements of the four-bar slider hinge assembly are also possible. For example, the pivot connection 26 of the main support arm 8 can slide along the sash panel 4 . In these arrangements, the remaining pivot connections, ie the pivot connections of the bridge support arm 10 and the hinge support arm 6 to the sash panel 4 , are all in fixed positions. However, as defined above, in all arrangements there are both fixed pitches and variable pitches. Further, the provision of a sliding connection between one or more components of the hinge assembly and the sash panel does not cause a change in geometry because the spacing between the connections of the other arms remains fixed.

To reiterate and for the avoidance of doubt, there are multiple relatively space-consuming fixed pivot connections and one or two slidable pivot connections in a brace. If there are two slidable connections, they are usually fixed relative to each other. Thus, there are multiple fixed spacings between the connectors and multiple (usually two) variable spacings between the connectors.

As used herein, the term "geometry" when used in relation to a stay hinge assembly includes the fixed spacing of the stays. The geometry of the stay hinge assembly is not the specific position or orientation of each component at any particular time, as it can change, for example, at any position during opening and closing of the sash. More precisely, the geometry includes a fixed spacing between the connecting parts of the support arms. In known stays, the geometry is fixed and in particular the spacing between the connections of the individual parts of the stay is fixed. One of the links to the sash panel will be movable (or both links can move together), but the other links are fixed relative to each other. The movable link is connected to a sliding friction block.

In order to ensure that the geometry of the assembly allows the tip 12 to be received securely in the plug 14, it is desirable to have a hinged support arm 6 which is longer relative to the other support arms than those used in known sliders. This causes the tip 12 to move away from the plug 14 substantially along the line of the sash panel 4 . The geometry used in known stay hinge assemblies may result in a travel of the tip 12 that collides with the plug 14 over time if the geometry becomes misaligned for some reason.

It is desirable to have a strut that accommodates the travel of the tip 12 out of the plug 14 before the tip 12 moves outwardly from the window frame. The inventor understands that this can be achieved by incorporating a longer hinge support arm 6, although this causes problems with the geometry of the hinge assembly 1 stopping alignment. In an exemplary arrangement, the hinge support arm may lie in the range from 10% to 30% longer than the hinge support arm used in fixed geometry with the same spacing as between the other connections.

As explained in detail below, the struts disclosed herein incorporate pitch changing means that allow for one or more fixed pitch changes. The distance changing means allow one or more fixed (ie non-slidable) links of the strut to be movable relative to other fixed links. This creates a gap in the location of the connector that can accommodate different sized support arms elsewhere in the brace hinge assembly. The pitch changing device is an exemplary way of changing the geometry of a brace hinge assembly.

FIG. 2 shows a perspective view of a portion of hinge assembly 101 . Many structural features of the hinge assembly 101 are the same as or similar to those of the hinge assembly 1 described above. These structural features are not described in detail with respect to FIG. 2 , unless necessary to describe the operation of the hinge assembly 101 , or they differ from corresponding structural features of the hinge assembly 1 . Similar structural features are given the same reference numerals, except for the preceding "10".

Hinge assembly 101 includes sash panel 102, sash panel 104 and three support arms: hinge support arm 106, main support arm 108 and bridging support arm 110, wherein bridging support arm 110 is between main support arm 108 and sash panel 104 extend. The arrangement of the hinge support arm 106 , the main support arm 108 and the bridging support arm 110 is substantially the same as the corresponding structure of the hinge assembly 1 . Further, connectors 116, 118, 120, 122, 124, and 126 (not shown in FIG. 2) are substantially identical, except for the exemplary arrangement of FIG. 126 is capable of sliding.

A pivot connection 126 (shown in FIG. 4 ) of the main support arm 108 to the sash panel 104 is slidable along the sash panel 104 via a main support arm slider 128 . The remaining pivot connections 118 , 122 to the sash panel 104 are the pivot connections of the hinge support arm 106 and the bridge support arm 110 . These connecting elements are normally fixed in known struts, as is the distance between them. In the exemplary arrangement of FIG. 2 , the pivotal connection of the hinge support arm 106 to the sash panel is in a fixed position, and the pivotal connection 122 of the bridging support arm 110 to the sash panel 104 comprises a spacing Change device 130. This allows the (usually) fixed spacing between these connections to change during opening and closing of the hinge assembly.

The main support arm slider 128 remains slidably connected with the sash panel 104 . In the example assembly 101 of FIG. 2 , the main support arm slider 128 is configured to travel along a channel in the sash panel 104 during opening and closing of the hinge assembly 101 . The bridge arm 110 is pivotally connected to the sash panel 104 by a slide 132 . In the exemplary assembly 101 of FIG. 2 , bridge arm 110 is pivotally connected to main support arm 108 at a central portion of main support arm 108 .

It should be noted that the one or more spacing changing devices 132 may be positioned at other locations on the strut in other exemplary arrangements. Further, the distance changing device may adopt other forms than those shown in the figure. For example, the spacing changing means may be provided at the pivotal connection 120 of the bridging support arm 110 to the main support arm 108 or any other pivotal connection of the hinge assembly 101 . Further, the spacing changing means may be integrated into one or more of the bridging support arms 110, for example by including a telescoping arrangement within the bridging support arms 110 (or any other support arms). Similarly, the same principles can be applied to other types of stay hinge assemblies, such as six-bar stay hinge assemblies.

The spacing changing means comprise a slide 132 which is movable into a first position (against a bumper 134) and a second position (against a bumper 138, shown in FIG. 2).

The main support arm slider 128 and the spacing changing device slider 132 are configured to slide along the sash panel 104 during the opening and closing operations of the hinge assembly 101. The sliders 132 are independently slidable along the sash panel 104 . That is, the slider 132 is not coupled to the pivot connection 126 of the main support arm 108 to the sash panel 104, or the slider 132 is not coupled to the pivot connection 118 of the hinge support arm 106 to the sash panel 104 . The pivotal connection 122 of the bridging support arm 110 connected to the sash panel is thus independently movable along the sash panel 104 and can be connected to the pivotal connection 126 of the main support arm 108 to the sash panel 104 or The pivotal connection 118 of the hinge support arm 106 to the sash panel 104 moves at different or independent rates.

In the exemplary assembly 101 of FIG. 2 , the connection of the hinge support arm 106 to the sash panel 104 is at a fixed location. The connection of the main support arm 108 to the sash panel 104 is slidable by means of the main support arm slider 128 .

The sash panel 104 includes a first bumper 134 . The first bumper 134 is prevented from moving on the sash panel 104 by protrusions 136 on the sash panel which hold the first bumper 134 in place. The first bumper 134 limits the movement of the slider 132 towards the leading edge segment of the assembly 101 . In addition, the second damper 138 is provided through the end surface of the fixing portion of the hinge support arm 106 connected to the connection piece 118 of the window frame panel 104 . The second bumper 138 limits the movement of the slide 132 towards the hinged end of the assembly 101 .

The carriage 132 is movable between two end positions defined by a first damper 134 and a second damper 138 . The first position is when the slide 132 abuts the first bumper 134, and the second position is when the slide 132 abuts the second bumper 138, which is hingedly supported in the exemplary assembly 101 of FIG. A portion of the connection between the arm 106 and the sash panel 104 is provided.

The independent movement of the slides 132 allows the spacing changing device 130 to accommodate increases in the length of the hinged support arm 106 . Movement of slide 132 between the first and second positions also represents a change in the geometry of hinge assembly 101 as the otherwise fixed spacing between links 118 and 122 changes.

Slider 132 is able to move without requiring movement of main support arm slider 128 . This may be the case for at least part of the opening or closing operation of the window. In particular, this may be the case when a movement is initially turned on and eventually turned off. In an exemplary arrangement, the initial opening movement may comprise an angle of the window from a fully closed position to open up to 10°. Similarly, final closing movement may include movement of the window from an angle of 10° or less to a fully closed position. Because the support arms are all pivotally connected, this movement will cause some movement of one or more of the other components of the hinge assembly 101 .

Because the hinge assembly 101 includes a pitch changing device, it is possible to use a longer hinge support arm 106 than a slider with a fixed geometry, into which the hinge support arm 106 can be integrated. It is to be noted that in other exemplary arrangements differently positioned pitch altering means can accommodate the use of other support arms having varying lengths.

Figure 3 shows the hinge assembly 101 in its fully closed position in cross-section. The sash panel 102 and frame panel 104 and the three support arms 106, 108, 110 are all parallel and adjacent. Due to the length of hinge support arm 106, when in the closed position, slide 132 is pulled toward bumper 134 against the bias of biasing mechanism 140, which in the exemplary arrangement is a spring.

It should be noted that the exemplary window assembly may not require the sash panel 102 and the sash panel 104, and other structures may be used to allow connection to the sash or frame and/or slidable connection to the frame.

The method of operation will now be described with reference to FIGS. 2 to 4 .

In the closed position, the main support arm slider 128 is pushed as far as it can travel towards the front edge end of the sash panel 104. When the bridge support arm 110 is pivotally connected to the main support arm, the slide 132 moves into its first position against the first bumper 134 and the biasing force of the spring 140 is overcome.

During the opening operation, the sash (not shown) and thus the leading end of the sash panel 102 is pushed generally in direction D outwardly. The sash panel 102 initially pivots about the setting end 112, and then as the sash panel 102 continues to move outward (in direction D), the pivotal connection 124 between the sash panel 102 and the main support arm 108 moves away from the frame panel 104. to move. The main support arm slider 128 is pulled towards the hinge end of the sash panel 104 , ie towards the plug 114 . This action releases the force on slide 132 , overcoming the biasing force of spring 140 . The spring 140 thus biases the slide 132 towards the second bumper 138 and into its second position. Tip 112 is thus pulled away from plug 114 . The spacing changing means 130 thus prevents the tip 112 from colliding with the saddle 114 which would occur because the hinge support arm was incorrectly dimensioned (eg too long).

During the closing operation, the sash panel 102 is drawn toward the frame panel 104 by the user continuing to pull the sash, and the hinge assembly 101 is attached to the sash in direction C. The support arms 106 , 108 , 110 pivot, thus allowing movement and rotation of the sash panel 102 . The biasing force of the spring 140 is sufficient to maintain the slide 132 in the second position during most of the closing operation. The main support arm slider 128 continues to move away from the plug 114 . In this way, the tip 112 of the sash panel 102 can reach the saddle 114 without colliding with the saddle 114 because the slide 132 is in the second position. When the sash enters the final stage of the closing operation, the main support arm slider 128 is pushed by the moving sash panel 102 as far as it can travel along the sash panel 104 away from the plug 114 . When the force applied to the main support arm slider 128 is now substantially aligned with the spring 140 , the bias of the spring 140 is overcome and the slider 132 moves back to its first position against the first bumper 134 . By having the slide 132 in its first position until the tip 112 is sufficiently close to the plug 114, collisions are avoided. Slider 132 must then be allowed to move to its first position to accommodate the incorrect length of hinge support arm 106 .

By allowing the slider 132 to move relative to the sash panel 104, the hinge assembly 101 is able to accommodate a hinge support arm 106 that is longer than is preferably adapted to use a slider having a fixed geometry.

In an alternative arrangement, the main support arm is pivotally connected to the sash panel at a fixed position and does not slide. Instead, the hinge and bridging support arms are connected to the sash panels by hinge and bridging support arm slides. In such an arrangement, the hinge support arm and bridge support arm slides are at least partially independently movable. Independent movement in this sense includes simultaneous movement in the same direction, but at different rates and/or by different amounts. The bumpers may be omitted to allow adequate travel. The slides may include a biasing mechanism to independently bias the slides of the hinge support arm slides to alter the geometry of the hinge assembly as shown in Figures 2-4.

A person skilled in the art can conceive further embodiments of the invention without departing from the scope of protection of the appended claims.
