Description

WINDOW SCORES

FIELD

[0001] The invention relates to window braces, in particular the invention relates to sliding window braces.

BACKGROUND S

[0002 3 Window braces (also known as window brace hinges or friction braces) are well known in the window industry. »Typically, a window brace connects the window frame to the window frame, and acts as a hinge. so that the window can be opened and closed. Often, a window frame will include a frame plate configured for affixing to the window frame, a frame plate configured for affixing to the window frame, and a number of arms pivotably connected between the frame places and the frame plate. . Window braces are available in many different configurations, depending on the type of window and type of opening mechanism required.

In a1g some struts already therein, there may be a cart that is capable of sliding on the frame plate. One or more of the arms may be attached to the cart as opposed to directly attached to the frame plate. The cart can then slide as part of the window opening mechanism.

For example, GB23113243, the contents of which is incorporated by reference, exposes a so-called 'four bar' window sill. The window brace includes a short arm and a long arm pivotally connected between the frame plate and the sash plate. The short arm is connected to the frame plate by a sliding cart. Under normal operation, the cart is restricted from sliding by a locking means, and the arrangement of the arms is such that the sash plate can be moved relative to the frame plate (corresponding to the window being operated from one position). closed to a first open position). Upon further operation, the locking means may be released, allowing the cart to slide over the frame plate, so that the window may be additionally opened from the first open position to a second open position. The treatment medium taught by GB23113243 includes a button formed integrally with a projection. The projection fits with the slide restraint frame plate. The projection is oriented to a position locked by a spring portion, also integrally formed with the knob. [00051 A problem associated with the window brace exposed by GB2311324B is that since the spring portion is made of plastic, the knob and the projection (being integrally formed with the spring portion) are also made of plastic. Projection subsequently experiences wear, affecting the performance of the locking medium over the life of the window strut.

An additional problem associated with window props including one. Sliding cart is the bezel plate must be configured to hold the cart. One approach is to form a. frame board using an extrusion process, so that the frame board has a profile suitable for use as a rail. For example, the window frame frame plate exposed by GB2311324B is an extruded length having a generally 'U' shaped profile on which the cart rests. a sliding arrangement.

A reference to any prior art in this descriptive report does not constitute an admission that such prior art forms part of common general knowledge.

The present invention may provide an improved window brace or at least provide the public with a useful choice.

DETAILED DESCRIPTION j.0.03 3] Figure 1 shows a window shade 1 according to one embodiment, Ά window shade 1 includes, a frame plate 2 for mounting on a window frame and a frame plate 3 for mounting on a window frame. Although neither the window frame nor the window frame are shown in Figure 1, it will be appreciated by those skilled in the art how a window frame of the present invention can be fitted with any suitable types of window frame and window frame resulting in a tilt type or swing type.

[0054] A carriage 4 is configured to slide on frame plate 2. A connecting element in the form of a short arm 5 and gaskets 6, 7 connects the carriage to the sash plate. An additional connecting element in the form of a long arm 8 and gaskets 9, 10 connects the frame plate to the sash plate. Joints 6, 7, 9, 10 may be any suitable type of pivoting joint, such as friction rivet joints, which are well known for this application. The arrangement of the connecting elements 5, 6 and joints 6, 7, 9, 10 allows relative movement between the frame plate 2 and the sash plate 3. As will be discussed in more detail below, this relative movement allows a installed window frame is moved from a closed position to an open position. One or more holes 11, 12, 13, 14, 15 are provided in the frame plate and the frame plate for receiving fasteners suitable for affixing the plate. frame to window frame e. from the sash plate to the window sash. 10055; Figure 1 shows the window strut 1 in an open position. In the partially open position, the window sash plane (not shown) is at an angle between 10 and 60 degrees with the window frame (not shown). In the mode of. 1, this angle is generally indicated by a dashed arc 16 and is about 32 degrees.

[0056] Figure 2 shows the window brace 1 of figure 1 in a closed position. In the closed position, the sash plane and window (not shown) is parallel to the plane of the window frame (not shown).

It will be appreciated from a comparison of FIG. 1 and FIG. 2 how the arrangement of the connecting elements 5, 6 and joints 6, 7, 9, 10 allows relative movement between the frame plate 2 and the It will be appreciated further that this allows the window sash to be shifted from the partially open position of figure 1 to the closed position of figure 2 (and again). It will further be appreciated for both the partially open position of FIG. 1 and the closed position of FIG. 2, that the carriage 4 remains in the same first carriage position in relation to the frame plate. As will be discussed in more detail below, the trolley may be restricted from sliding on the bezel for a period of 11 inches to 1.7. (0058.) Figure 3 shows the window sash 1 of Figure 1 in a fully open position In the fully open position, the plane of the window frame (not shown) is at an angle between 60 and 110 degrees with the window frame plane (not shown). In the embodiment of Figure 3, this angle is generally indicated by a dashed arc 3.8 and is about 71 degrees. It will be appreciated from a comparison of FIG. 1 and FIG. 3 how the arrangement of connecting elements 5, 6, joints 6, 7, 9, 10 and carriage 4 allows relative movement between the frame plate 2 and the. sash plate 3. It will be further appreciated that this therefore allows the window sash to be shifted from the open position parallel to figure 2 to the fully open position of figure 3 (and back again). To allow the window sash to be moved from the open position: · sliding 1 minute from figure 1 to open the carriage, the carriage 4 is allowed to slide along the frame plate 2 from the first one. trolley position to the second trolley position.

Figure 4a shows a partial view of the window brace of figure 1 to show cart 4 in more detail. The carriage includes a carriage body 19 and a hitch mechanism 17. The carriage body is configured to slide on the frame plate 2. The carriage 4 further includes flanges 20 as shown in the bottom view of figure 4b extending along the sides of the carriage 4. The flanges 20 effectively wrap around the lower side of the frame plate 2, thus keeping the carriage in a fixed relationship with the frame plate 2 while still allowing the carriage to slide along the length of the bezel plate (as shown by the arrows K). The trolley body can be made from any suitable material. Preferably, the trolley body is made from plastic. This is easily molded and results in less friction as the trolley body slides on the frame plate.

The coupling mechanism 17 of carriage 4 includes a button 2-1 and a coupling element 22. The coupling element engages with a notch 23 provided in the frame plate 2. This restricts carriage 4 from sliding on the frame board. When the concrete 21 is depressed, the engaging member 22 is detached from the notch 23, thus allowing the cart to slide on the frame plate. In use, a user may wish to open the window frame from partially open to fully open, and thus, he may press button 21 to disengage the engaging mechanism and to disengage, [0062] Fig. 5 shows a cross-sectional view of cart 4 of Fig. 1 to further demonstrate the structure of the cart. Figure 1 shows the short arm 5 connected to the cart by a rivet joint 1. The cart body 19 is wrapped around the frame plate 2 with one. flange 20 shown on the underside of the frame plate 2. The carriage 4 may further include an insert 24. The short arm 5 is connected to the carriage body 19 and the insert 24. One such insert. It can be made of metal, providing more rigidity to the cart. The insert can also act as a fail-safe structural element in case the cart body fails (for example, if the cart body has melted in a fire). The metal insert would retain the short arm and remain affixed to frame plate 2. The metal insert extends to flanges 20. In one embodiment, flanges 20 may be integrally formed with the insert.

[0063] A. Figure 5 shows the coupling mechanism 17 in more detail. The coupling mechanism includes a knob 21 and a coupling member 22. The carriage body 19 is configured to accommodate the coupling mechanism. The knob and the coupling element may be formed into. so that when the button is pressed the coupling element is moved. In figure 5, the coupling mechanism 1.7 is shown in a engaged position. In the engaged position, the engaging mechanism is engaged with the frame plate 2. In particular, the engaging member 22 is engaged in a notch 23 located on the frame plate. With the engaging member engaged in the notch, the carriage is engaged and restricted from sliding on the frame plate 2. In the engaged position, button 21 is not depressed. The engaging mechanism includes a guide member 25. The guiding member orientates the engagement mechanism to the engaged position. The guide member 25 is integrally formed with the carriage body 19. In a preferred embodiment, the carriage body and The guide member is formed of plastic. Such plastic may be chosen to provide the guide member 25 with the required restorative force (i.e., for the provision of force, sufficiently to orientation of the coupling mechanism 17 to the engaged position). By having the guiding element formed with the cart body, the manufacture and assembly of the cart is simplified. As will be discussed in more detail below, having the orientation element not formed with. The engaging mechanism The engaging mechanism can then be formed from a high strength material such as metal.

Fig. 6 shows the same view of the cart as Fig. 5 with coupling mechanism 17 in the disengaged position. At. In the disengaged position, the engaging mechanism is disengaged from the frame plate 2. In particular, the engaging member is disengaged from the notch 23 in the frame plate. With the coupling element detached from the notch, the carriage is allowed to slide on frame plate 2. In the disengaged position, button 2.1 has been pressed. In one embodiment, the trolley body 19 may include a latch 26 that is configured to interact with an edge 27 of the engaging mechanism such that the engaging mechanism is held in the temporarily disengaged position. A latch such as this can be used to prevent a user from having to manually hold button 21 while still trying to slide cart 4 from his or her first post. In the disengaged position, the orienting element 25 is compressed, so that the orienting element tends to orient the engaging mechanism 17 to the engaged position. It will be appreciated that latch 26 must be configured such that the guide member 25 itself does not defeat the latch. The engaging mechanism includes a projection 28 extending away from the button 21. The frame plate 2 may include a recess 29 to accommodate that projection when the button is pressed. When the carriage 4 begins to slide along the frame plate 2, the projection 28 hits a recess rope 30, the edge is suitably arched so that it forces the projection to cirna, which together with the frame member. orientation 25 is sufficient to overcome the latch 26. Therefore, once the carriage 1 slides over the frame plate, the engaging mechanism 17 is no longer retained by the latch. Then, if the engaging member 22 encounters a notch, the engaging mechanism returns to the engaged position.

[0.066] Em. A preferred embodiment, the engaging mechanism 17 is made from a high strength material such as metal. It will be appreciated that for the lifetime of a particular window strut the coupling mechanism may be used many times. This can impose not insignificant wear and stress on the components, particularly those with an interface with other parts of window brace 1, such as; • the engaging member 22 which has an urn. having a face with the notch 23 of the frame plate 2, which itself is preferably made of metal; The edge 27 of the engaging mechanism 17 which has an interface with the latch 26; and • projection 28 which. has an interface with the edge 30 of the recess.

Additional wear and tension is supported by the engaging member as it supports a significant portion of the weight of the window frame through the short arm (particularly in baseuant type windows). Having the coupling mechanism made of a high strength material, these components will not wear out and deteriorate as quickly. This will improve the ability of the window brace to function as intended for the life of the window brace.

Returning to Figure 1, an additional notch 31 and an additional recess 32 are also shown on the frame plate 2. It will be appreciated that as carriage 4 slides into the second carriage position of the fully open configuration (as shown in Figure 3), the engaging member will engage with the additional notch 31, thereby engaging the cart in the second cart position. Figure 7 shows a cross section of the window strut of Figure 3. Figure 7 shows the engaging member 22 engaged in the additional notch 31.

[0.069] It will be appreciated from the above description that the frame plate 2 must be configured to work with carriage 4 so that the carriage is fixed to the frame plate while still being able to slide along the length. In one embodiment, the frame plate may be extruded with a profile that is suitable for the particular geometry of the cart. However, in a preferred embodiment, the frame plate is formed by stamping, pressing or a similar process from stainless steel.

[0070] Figure 1 shows the window brace frame plate 2 discussed above with respect to figures 1 to 7. The frame plate is formed from a generally flat elongate member. The frame plate includes holes II.13 for receiving suitable fasteners for attaching the frame plate to the window frame (not shown). The bezel plate includes an additional hole 33 for connection to the long arm (not shown) by a suitable gasket. The frame plate also includes notch 23., recess 29, additional notch 31. and additional recess 32 discussed above. It will be appreciated that the holes, notches and recesses may be formed in the frame plate by any suitable process, such as, for example, punching, punching or stamping.

Frame plate 2. includes a first affixing section 34 and a second securing section 35. Ά first affixing section and the second securing section are configured to affix the framing plate 2 to the window frame (-not shown). For this purpose, the first display section 34 is provided with a hole 11. and the second display section is provided with a hole 13.

Frame 2 also includes a rail section 36 which extends between the first display section 34 and the second display section 35. The rail section is connected to the first display section by a first section. 37 and the second attachment section by a second elevation section 38. The elevation sections 37, 38 are generally inclined or perpendicular to the plane of the frame plate, and serve to elevate the rail section 36 with respect to the first section. 34 and the second display section 35. The rail section is raised so that when the frame plate is installed, the rail section is separated from the window frame (not shown) by a space as indicated by arrows B in figure 8. For skin minus a portion of the length of the rail section 36, the space extends from one edge of the rail section 39 to the other edge of the rail section (i.e. extends across the transverse width of the rail section).

The rail section 36 provides a region in which a trolley can slide (as discussed with reference to figures 1 to 7}. In particular, the space is sufficient to accommodate the trolley flanges so that the trolley is retained on the rail section while sliding along the rail section The rail section may include a recess 41. The recess may include an additional hole 12 for receiving multiple fasteners affixing the recess to the window frame. Ά recess may increase the stiffness of the rail section.It will be appreciated that the recess is positioned towards the middle of the cross section width of the rail section so that a sufficient amount of the rail section remains for retaining the trolley to the rail section. (as indicated by the arrows C), The recess can be positioned so that it does not break the flanges, and in the form of the 1 izarsohre a r e n n r r n c i a.

The first elevation section 37 and the second elevation section 38 may be formed by a stamping process. 'Tapping' will be understood to include any type of forming process pressing. Those skilled in the art will appreciate how a stamping g e r at 1 m then e f u n c 1 o n e not r e c e s and r e x p. 1 i c a d e m details. Briefly, the embossing includes placing the generally flat elongate member on a printing press. which has a suitable mold or matrix. The printing press then subjects the generally flat elongate member to sufficient pressure so that it deforms to the shape of the mold or die. matrix. In this case, the sta.mpa.gem process forms the first elevation section · 37 and a. second elevation section · 38, thus also resulting in rail section 36 being elevated with respect to prim *>; > I affix 4 and à. second securement of the attachment 35. The same embossing process can be used simply for forming some or all of the recess 41, the holes 11, 12, 1.3, 3.3, the notches 23, 31 and the recesses 29, 32.

[C 075,] Preferably, the frame plate is made from one. metal. In one particular embodiment, a. Bezel plate is made from stainless steel.

Figure 9 shows a view of the underside of the window brace 1 of figure 3- (i.e. in the fully open position). Cart 4 is engaged in the second cart position. The figure demonstrates how the flanges 2.0 will wrap around the outer edges of the rail section, so as to retain the carriage on the rail section 3.6 of the frame plate 2.

[0077] Cart 1 may be prevented from sliding off of the 36 era rail section. one direction by the second lifting section 38. In particular, the carriage flanges 20 are unable to slide in front of the second lifting section. However, the first elevation section may include indentations 43 defining edges 44, so that the first elevation section does not prevent carriage 4 from slipping off the rail section. In particular, the carriage flanges are capable of sliding in front of the section elevation section. That is, at least a portion of the first elevation section has a width transverse to the length of the frame plate. In the frame plate 2 embodiment shown in Figure 9, the indentations 4.3 extend partially to the rail section 36 and fully to the first section. 34, The indentations 43 allow the trolley to slide into and out of the cross section during window mounting and dismounting. 1. In one embodiment, after carriage 4 has been slid into the rail section (for example, during window brace fabrication), the first section 34 of frame plate 2 may be suitably fastened or stabbed for creation. of a stop. Thus, when the window strut 1 is installed, the stopper can permanently prevent the frame plate 2 from sliding back in front of the cutouts 43 and being removed from the rail section 36.

Figures 10a to 10c show window sash 1 installed in a window 4.5 showing a section of both window sash 46 and window sash 47. It will be appreciated that the window sash can be installed with any suitable type of window frame and window sash resulting in. a tilt-type or swing-type window. Further, there may be one or more window sills (usually two or more) installed by particular window sash.

In figure 10a, the window 45 and the window brace are in the closed position. The window brace is not visible as it is healed by window frame 47. In figure 10b, window 45 and window brace 1 are in the partially open position. Cart 4 is in the first cart position relative to frame plate 2. In figure 10c, window 45 and window strut 1 are in the fully open position. Cart 4 is in the second cart position relative to frame plate 2.

[.0.080] Figures 11 to 20c illustrate a second embodiment of window sash 1. This arrangement is shown with respect to a window shank smaller than that of figures 1 to 10c. However, each embodiment may be extended to a window shank of any desired size. It is. The second embodiment is generally similar to the first embodiment described above.

[0081] Figure 11 shows a window brace 3 including a frame plate 2 and a sash plate 3.

A carriage 4 is configured to slide on frame plate 2. A connecting element in the form of a short arm 5 and gaskets 6, 7 connects the carriage to the sash plate. An additional connecting element in the form of a long arm 8 and joints 9, 10 connects the frame plate to the sash plate. One or more holes 11, 12, 13, 14, 15 are provided in the bezel and sash plate to receive suitable fasteners for affixing the bezel to the window frame and the sash plate below. ane1a.

Figure 11 shows window sash 1 in. urn. open position, partner Intente. Figure 12 shows the window brace 1 of figure 11 in a closed position. In both a. partially open position of FIG. 11 and the closed position of FIG. 1.2, carriage 4 remains in the same first carriage position with respect to the frame plate.

Figure 13 shows the window brace 1 of figure 11 in a fully open position. To allow the window frame to be moved from the partially open position of figure 11 to the fully open position of figure 13, the carriage 4 is allowed to slide along the frame plate 2a. from the first cart position to the second content position.

[00.84] Figure 14a shows a partial view of the window brace of figure 1 to show cart 4 in more detail. The cart is generally constructed similar to that of Figures 1 to 10c. However, the orientation of the coupling mechanism 17 has been reversed, as can be seen by comparing figures 4a and 14a. The carriage includes a trolley body 19 and an engaging mechanism 17. The carriage body is configured to slide on the frame plate 2. Cart 4 further includes flanges 20 as shown in the lower side view of figure 14b extending along the sides of cart 4. The The flanges 20 effectively wrap around the underside of the frame plate 2, thus keeping the trolley in a fixed relationship with the frame plate 2, while still allowing the trolley to slide ... Lze along the length of the frame plate frame. In this embodiment, the flanges may be provided by insert 24 and bends 20a formed in the material of the carriage body 19.

The mechanism 4 to 17 of carriage 4 includes a button 21 and a locking element 22. The locking element fits with a notch 23 provided in the frame plate 2. This restricts the carriage 4 sliding on the bezel. When the button 21 is depressed, the engaging member 22 is detached from the notch 23, thus allowing the carriage to slide on the frame plate.

Figures 15 and 16 are cross-sectional views of carriage 4. As shown, the projection 28 of the engaging mechanism 17 is formed with a step 2-8 'to engage the latch 26 in the position of Figure 16. Still In this embodiment, the recess 29 in the frame plate 2 is formed by a stamping or punching operation, which leaves the frame plate material in place, but deforms it to provide a recess 29 with a ramp structure, providing less resistance to a projection 28 movement out of the recess 2.9. In other words, in this embodiment, recess 29 does not consist of an opening through the frame plate. This construction can also be seen in figure 16, for example.

[0 0 8 8] O c a r r i n h o 4 a i n. d a d e i n c 1 u i r an i, n s e ration 24 similar to that of Figures 1 to 10c. The engaging mechanism includes a bearing of orientation 25 similar to that of figures 1 to 10c. However, beyond. In addition, an additional spring 49 may be provided acting against an end surface of the coupling mechanism 17. This spring 49 also tends to force the coupling mechanism 17 to the disengaged position shown in figure 15 by acting downward (as shown ) against the end of the coupling mechanism 17.

Figure 11 also shows an additional notch 31 and an additional recess 32 in the frame plate 2 which operate similarly to those of figures 1 to 10c.

In this embodiment, one or more friction elements 50 may be provided on the frame plate 2. These friction elements act to stop the movement of the carriage 4 rapidly upward when the strut and window are in the fully open position. and the engaging mechanism 17 is released. In the fully open position, when the engaging member is released, the friction elements 50 prevent or slow down movement of the window frame. The frame may be moved, however, in a user-controlled manner after a coupling mechanism disengagement. The user simply applies a force to the window frame to overcome the atheristic force created by the friction elements. The friction elements 50 also slow the movement of the carriage 4 as it approaches the fully open position. This helps to limit damage to the mechanism, which can be caused by sudden snapping with the additional notch 31 and the additional recess 32 while moving at too high a speed.

In the embodiment shown, the friction elements 50 simply consist of raised ridges embossed or pressed into the frame plate 2 which engage with channels 51 formed in the cart. However, in other embodiments, inserts or additional elements of a high friction material (e.g., rubber or a suitable polymer) could be used, (00931. Figure 18 shows the window sill molding plate 2 of Figure 11, Figure 19 shows a view of the underside of the window sash 1 in the fully open position. Figures 20a to 20c show the window sash 1 installed in a window showing a section of the window frame 46 and the window frame. window 47.

The embodiment of figures 11 to 20c is similar to that of figures 1 to 10c, other than the differences cited above. This embodiment may be made and used in a manner similar to that described above with reference to Figures 1 to 10c. Figures 21 to 30c illustrate a third window strut mode. Components similar to those in Figure 1 are designated with the same reference numbers. Window brace 3. includes a frame plate 2 for mounting to a window frame and a sash plate 3 for mounting to a window frame. The window shank 1 can be installed with any suitable types of window frame and window sash resulting in a tilting type or jamb type window. A trolley 4 is configured to slide the frame plate 2, A connecting element in the form of a short arm 5 and joints 6, 7 connects the trolley to the sash plate. An additional connecting element in. The shape of a long arm 8 and joints 9, 10 connects the frame plate to the sash plate. Joints 6, 7, 9, 10 may be any suitable type of pivot joint, such as friction rivet joints, which are well known for this application. The arrangement of the connecting elements 5, 6 and the joints 6, 7, 9, 10 allows relative movement between the frame plate 2 and the sash plate 2. This relative movement allows an installed window frame to be .moved from a closed position to. an open position. One or. Further holes 11, 12, 13., 14, 13 are provided in the frame plate and the receiving frame of suitable pxen.dedor.es suitable for attaching the frame plate to the window frame and plate from frame to frame. from j, aneja.

[.0098.] Figure 21 shows the anchor of window 1 in a partially open position. In the partially opened position, the window frame plane (not shown,) is. in. one, angle between 5 and 50 degrees as plane of window frame (not shown). In the embodiment of Fig. 21, this angle is indicated by a dashed arc 16 and is around 3 degrees. 0099] Figure 22 shows the window brace 1 of figure 21 in a closed position. In the closed position the plane of the window frame (not shown) is parallel to the plane of the window frame (not shown).

[01.0,0-3 A comparison of FIG. 21 and FIG. 22 shows how the arrangement of connecting elements 5, 6 and joints 6, 7, 9, 10 allows relative movement between the frame plate 2 and the sink. This therefore allows the window frame to be shifted from the open position to Figure 21 to the closed position of Figure 22 (and back again). the partially open position of FIG. 21 and the closed position of FIG. 22, the carriage 4 remains in the same first carriage position with respect to the frame plate. The carriage may be restricted by sliding on the frame plate by a mechanism. of coupling 217.

Figure 23 shows the window brace 1 of figure 21 in a fully open position. In the fully open position, the window frame plane (not shown) is at an angle between 50 and 100 degrees with the window frame plane (not shown.). In the embodiment of Fig. 23, this angle is generally indicated by a dashed arc 18 and is around 73 degrees.

[0102] A comparison of Figure 21 and Figure 23 shows how the arrangement of connecting elements 5, 6, joints 6, 7, 9, 10 and carriage 4 allows relative movement between the frame plate 2 and the This therefore allows the window sash to be shifted from the partially open position of figure 21 to the fully open position of figure 23 (and back again). To move the window frame from the partially open position of Figure 21 to the fully open position, the carriage 4 has been moved along the frame plate 2 from a first carriage position to a second carriage position.

[1) 103j Ά Figure 24a shows Cart 1 in more detail. Trolley 4 includes a trolley body 219 and a coupling mechanism 217. Trolley body 219 is configured to slide on the frame plate 2. Trolley 4 further includes Larges 220. as shown in the underside view of the figure. 4b extending along the sides of the carriage 4. The flanges 220 effectively coil at the underside of the frame plate 2, thereby securing the carriage 4 to the frame plate 2 while still allowing the carriage to slide along the frame. frame plate length (as shown by arrows A). The trolley body can be made of any suitable material. Preferably, the cart body is made of plastic. It is easily molded and results in less friction as the trolley body slides on the frame plate.

The carriage 217 coupling mechanism 4 includes a selection switch 226 and a coupling element 222. The coupling element 22: 2 fits with a stepped recess 223 provided in the frame plate 2. This restricts the carriage 4 sliding on the bezel. When the selector switch 226 is moved laterally, the engaging member 222 is free to slide up the ramp 221 in recess 223, thereby allowing the cart to slide on the rr plate older a. In use, a user may wish to open the window sash from partially open to fully open, and thus he may slide the selector switch 226 i ϊ r i ir., · To iesenga Lai o .. ui Lsí. . «. fu release the cart 4.

[0105] Figure 2.5 shows a north view of trolley 4 to better demonstrate the trolley structure. The trolley 4 may further include a structural insert 224. The short arm 5 is connected to the trolley body 219 and the insert 224. This insert may be made of metal, providing more rigidity to the trolley. Insertion can also act as a fail-safe structural element in the event that the trolley body fails (for example, if the trolley body has melted in a fire). Insert 224 would retain the short arm and remain affixed to frame plate 2. Insert 224 extends to flanges 220. In one embodiment, flanges 220 may be integrally formed with the insert.

In Figure 25, the coupling mechanism 21? is shown in a engaged position. In the engaged position, the engaging member 222 is engaged with recess 223 located on the frame plate 2. With the engaging member 222 engaged with recess 223, the carriage 1 is engaged and restricted to a slack in the frame plate 2, Engagement mechanism 217 includes a guide member 225. The guide member orientates or forces the engage member 222. into recess 223. The guide member 225 may be spring or the like to provide the guide member 225 is the required restoring force (i.e., to provide sufficient force to orient the engaging member 222 to the engaged position). The spring may be housed in a cylindrical recess in the engaging member 222, which is seated against a recent 227 on the underside of the selector switch 22.6. The engaging element 222 is restricted to a single axis of normal travel to. plate (2.107] Figure 2.6 shows the same view of the cart as in Figure 25, with the coupling mechanism 217 in the disengaged position. In the disengaged position, the coupling mechanism · is detached from the In particular, the engaging member 222 is detached from recess 223 on the framing plate 2. With the detached engaging member of recess 223, the carriage is allowed to slide into the framing plate 2. In the disengaged position selection switch 226 has been moved laterally In this position, when the user pushes the window open further, the engaging element 222 is free to slide up the ramp 221 and frame plate 2. £ .0106] selection 226 is mounted between carriage body 219 and insert 224. This provides a channel which is transverse to the sliding geometry axis of carriage 4. Selection switch 226 can therefore be moved by the user in the channel from position en.gata.da A detent between the selector switch 26 and the trolley body 219 provides a predetermined resistance to hold it in place in the desired engagement position. The detention is designed to be easily overcome by the user moving between hitch positions. This detention also provides some audible feedback to the user when the new hitch position has been reached, [0109] Thus, the user may not need to keep the selector switch 226 in position while opening the window to its open position. fully. The operation can be done with one hand, firstly by switching the position of the selector switch 226 and secondly by opening the window to its fully open position.

In a preferred embodiment, the mechanism of e n g a t e 217 is f e i. t ci parti r of a mate r L a 1 .. of alpha resistance, such as plastic. The plastic :; iarnenie is cheap, which easily allows a soup sole.

Returning to Figure 21, there is also a second recess 231 and a second ramp 232 on the frame plate 2. As the carriage 4 slides in the second position of the fully open configuration cart (as shown in Figure 35, the coupling element 22-2 will fit into the box 211, o. . u 1: cart in the second cart position. Figure 27 shows a cross section of the engaging member 222 engaged in recess 231.

As can be seen, the first recess 22-3 and the second recess 231 are generally opposite, so that the locking position for the engaging member 222 is to one side in the open wall position 1 and to the other. side in the fully open position. Carriage 4 may include the markings 233 (seen in Fig. 24a) to designate the locking position for the engaging member 222 with respect to the condition of Liner. t; e open or ptename rds open.

[0113] Frame board 2 can be configured to work with carriage 4 so that the carriage is fixed to the frame board while still being able to slide along the length of the frame board. In one embodiment, the frame plate may be extended with a profile that is suitable for the particular geometry of the cart. However, in a preferred embodiment, the framing plate is formed by stamping, pressing or by some means. r t i r of steel i. η o x 1 gives v e 1.

Figure 28 shows the window brace frame plate 2 discussed above with respect to figures 21 to 27. Frame frame 2 is formed from a generally planar elongate member. The bezel includes holes 11, 13 for receiving suitable fasteners for affixing the bezel to the window frame (not shown). Frame plate 2 includes an additional hole for connection to the long arm (not shown) by gasket 10 (not shown). Frame plate 2 also includes first ramp 221, first recess 223, second ramp 232 and second recess 231 discussed above. It will be appreciated that the holes, notches and recesses may be formed in the frame plate by any suitable process, such as, for example, punching, punching or stamping.

[0115j Frame board 2 includes. a first affixing section 234. and a second affixing section 235, The first affixing section and securing securement section are configured to secure the frame plate 2 to. frame plate; not shown). For this purpose, the first affixing section 23-5 is provided with a frame II and the second affixing section 235 is provided with a hole 13. 10116] Frame plate 2 also includes a rail section 236 extending between the first affixing section 234 and a. second display section 235. A. Rail section 236 is connected to the first display section 2.3.4 by a first lift section 237 and to the second display section 2:35 by one. second elevation section 238. Elevation sections 237, 238 are generally inclined or perpendicular to the plane of the frame plate and serve to elevate the choir rail section 236. respect to the first affixing section 234. and the second affixing section 235. The rail section is raised so that when the frame plate is installed, the rail section is separated from the window frame (not shown ) by a space, as indicated by the arrows 5 in Figure 28. At least a portion of the length of. rail section 236, the space extends from one edge of the rail section 233 to the other edge of the rail section (i.e. extends across the transverse width of the rail section).

[01.177] Rail section 2 36 provides a region in which a carriage 4 can slide. In particular, the space is sufficient to accommodate the flanges 220 on the cart so that the cart 4 is retained on the rail section 236 while sliding along the rail section 236.

The first elevation section 237 and the second elevation section 238 may be formed by a stamping process. 'Stamping' may include any type of forming process pressing. Those skilled in the art will appreciate how an embossing generally works and need not be explained in detail. Briefly, embossing includes placing the generally flat elongate member in a embossing press having a suitable mold or die. The embossing press then subjects the generally flat elongate member to sufficient pressure so that it deforms to the shape of the mold or die. In this case, the embossing process forms the first elevation section 237 and the second elevation section 233, thus also resulting in the rail section 236 being elevated with respect to the first attachment section 234 and the second attachment section 23. 5. The method of this method is used simultaneously for the formation of some or all of the holes 11, 12, 13, recesses 223, 231 and ramps 221, 23. For example, recesses 223, 23] .. and ramps 221, 232 may be formed by the ramp section being affixed to one end of the frame plate 2 and sloping therefrom. The other end of the ramp is attached to the rectangular section which can be punctuated from the frame plate but is spaced therefrom. The rectangular section forms a. recess base and sides open. The edge of the aperture punctured in the frame plate 2 is an impact plate for. the coupling element 2 2.2 in position and ng a t a da. 10119] Preferably, mind, the sink. The frame frame is made from one. metal. In one particular embodiment, the frame plate 2 is made from stainless steel. By providing the trolley 4 with flanges 220 which wind it around the frame plate 2, this may allow extrusion of a significantly simpler and / or cheaper frame plate. For example, the frame plate 2 may be substantially flat in the side cross section, as opposed to a U-shaped cross section used for cart restraint in prior art designs. The elasticity in the flanges 20 may also allow less resistance to the user move between partially open and fully open and / or longer life / higher reliability.

[Q12 € q Figure 29 shows a view of the underside of jib t 1 of figure 23 (i.e., fully open position). Cart 4 is engaged to the second cart position. flanges 220 wrap around the outer edges of the rail section 236 so as to retain the carriage on the rail section 236 of the frame plate 2.

[0121] The first elevation section 237 may include indentations 243 defining the edges 244 so that the carriage flanges are capable of sliding in front of the section elevation section. That is, at least part of the first elevation section has. a width transverse to the length of the frame plate which is narrower than a width of the rail section transverse to the length of the frame plate. In the frame plate 2 embodiment shown in Fig. 29, the cutouts 243 extend partially to the rail section 243 and fully to the first section 234. Cutouts 243 allow the carriage to slide to and from the section. rail during mounting and even act on the window brace 1. On. In one embodiment, after the carriage 4 has been slid over the rail section (for example, during window brace manufacture), the first section 234 of the frame plate 2 may be suitably fastened or stabbed 24 0, 241 (Figure 28 ) for creating a stop. So when the window anchor. 1 is installed, the permanent stop may prevent carriage 4 from sliding back in front of cutouts 243 and being removed from rail section 243.

Figures 30a. 3.0c will show window frame 1 installed on window 45. showing a section of frame, window frame 4t and window frame 47. window frame can be installed with any suitable type of frame. window frame and window sash »resulting in either a knocker type or a knocker type window. .There may be one or more usually two or more window sills installed per particular window frame.

[01.23] In figure 3.0a, window 45 and window brace 1. are in the closed position. The anchor of window 1 is not visible as it is buzzed through the sash window 47. Figure 3.G.h, window 45 and window strut 1 are in the partially open position. Cart 4 is in the first cart position with respect to frame plate 2. In Figure 30c, window 45 and window strut 1 are in the fully open position. Cart 4 is in the second cart position relative to frame plate 2.

Although the window braces described above are window braces of the four bar type, those skilled in the art will appreciate how the cart with hitch mechanism and frame plate can be used in other window brace configurations having one. sliding cart.
