Description

Window stay and window

Technical Field

The present invention relates to a window stay (window stay), and more particularly, to a window stay having a carriage movable along a rail of a frame plate (frame plate).

Background

The window may have one or more window stays to allow the sash to move relative to the frame.

One form of window brace is a four-bar window brace. The four-bar window stay has a frame plate attached to the window frame, a sash plate attached to the sash, and short and long arms connecting the frame plate and the sash plate. The long and short arms allow the sash to be opened at an angle with respect to the frame.

In some cases, the short arm is attached to a carriage, and the carriage can slide along the track of the frame plate. This allows the sash to open in a different configuration relative to the sash.

Disclosure of Invention

In a first exemplary embodiment, there is provided a window brace including: a frame plate configured for attachment to a window frame, the frame plate comprising a rail and a stop (stop) at an end of the rail; and a carriage configured to move along the track, the carriage comprising an abutment; wherein the abutment portion is configured to abut (abut) the blocking portion when the carriage moves to an end of the rail.

In a second exemplary embodiment, there is provided a window brace including: a frame panel configured for attachment to a window frame, the frame panel including a track; and a carriage configured to move along the track; wherein the edges of the frame plate are configured to prevent the carriage from moving past the ends of the frame plate.

Detailed Description

In some embodiments, the window brace has a carriage configured to move along the track of the deckle. This may enable the window to be moved between a normal mode (in which the sash may be opened at an acute angle to the frame) and a cleaning mode (in which the sash may be opened approximately at right angles to the frame). The edge of the frame plate prevents the carriage from moving past the end of the frame plate, for example by having an abutment which abuts a stop of the frame plate. This end may be the end opposite the connection between the frame plate and the long arm. This limits the sliding of the carriage off the track of the frame plate and, in case of strong forces (as may occur in windy conditions), may reinforce the other limiters.

Fig. 1 illustrates an exemplary window brace.

The window brace has a sash plate 100 configured to be attached to a window frame. The bezel 100 is generally flat and elongated and may have a length and width similar to the edges of a window frame. The bezel 100 may be made of a relatively high strength material, such as aluminum or steel. A plurality of fixing holes 101 are distributed along the length of the frame plate 100. Screws or other fasteners may pass through the fixing holes 101 and into the window frame (or corresponding fixing holes or fastener receivers in the window frame). This allows the bezel 100 to be securely attached to the window frame.

The long edge of the bezel 100 has a lip 130 that projects laterally from the main body of the bezel 100. The edges of the lip 130 may be generally rounded. The lip 130 may have a thickness that is less than the thickness of the body of the bezel 100.

The carriage 500 moves longitudinally (i.e., along axis B-B) along a track defined by the lip 130 of the bezel 100. The carriage 500 has a recess. The recess is defined by an inner surface 501 of the body of the carriage 500 and a pair of L-shaped arms 502 depending from the body of the carriage. The L-shaped arms 502 each define a respective channel 530 configured to receive the lip 130 on each of the two sides of the bezel 100. The fit between each lip 130 and the respective channel 530 may be such that the carriage 500 is substantially unable to move laterally (i.e., parallel to axis C-C). There may be low friction between each lip 130 and the respective channel 530 to allow the carriage 500 to move along the track. For example, a force of less than about 2.5Nm may be sufficient to slide the carriage 500 along the track. The carriage may be made of a self-lubricating material, such as plastic, to allow the carriage 500 to slide along the track.

The blocking portion 120 protrudes from an outer surface of the bezel 100 (i.e., a surface that does not abut the window frame). The blocking portion may be stamped or punched out of the frame plate 100. The stop 120 is located in a U-shaped recess 520 of the carriage 500 to limit the movement of the carriage 500. When the carriage 500 moves towards the end 102 of the frame plate 100, the blocking portion 120 abuts the end of the recess 520. This prevents further movement of the carriage 500 towards the end 102. In this position, the end 102 of the bezel 100 may be flush with the carriage 500. Since the recess 520 is open, the blocking portion 120 does not hinder the carriage from moving towards the end 103 of the frame plate 100.

The latch 110 is provided on an outer surface of the bezel 100. The latch 110 moves between a latched mode and an unlatched mode. In the latching mode, the latch 110 abuts an inner surface of a latch recess 503 located in the carriage 500. Latch 110 blocks carriage 500 from moving along the track toward end 103. In the unlatched mode, the latch 110 is positioned closer to the outer surface of the bezel 100. The latch 110 does not abut the latch recess 503 and therefore does not impede the carriage 500 from moving along the track towards the end 103. Latch 110 may be biased toward the latched mode by a spring or other biasing device. The latch 110 may be moved from the latched mode to the unlatched mode by a force on the latch 110 toward the outer surface of the bezel 100. The force may come from the user or from the carriage 500 moving towards the end 102.

The window stay has a sash plate 200 configured to be attached to a window sash. The fan plate 200 is generally flat and elongated and may have a length and width less than or equal to the edge of the sash. The length and width of the fan plate 200 are generally less than the length and width of the bezel 100. The fan plate 200 may be made of a relatively high strength material, such as aluminum or steel. A plurality of fixing holes 201 are distributed along the length of the fan plate 200. A screw or other fastener may pass through the securing hole 201 and into the sash (or a corresponding securing hole or fastener receiver in the sash). This allows the fan plate 200 to be securely attached to the sash.

The frame plate 100 and the fan plate 200 are connected by a long arm 300. The long arms 300 are pivotally connected at the frame panel fixing points 301 and the fan panel fixing points 302 by respective fasteners. The fasteners may be rivets, screws, or other types of fasteners that allow the elongated arm 300 to pivot relative to the frame and

fan plates

100, 200. The long arm 300 is substantially flat and elongated. The length of the long arm 300 defines (at least in part) the angle at which the sash can be opened relative to the frame, and may be selected according to the desired angle. The width of the long arm 300 may be less than or equal to the width of the bezel 100.

The fan plate 200 and the carriage 500 are connected by a short arm 400. The short arm 400 is pivotally connected at a carriage fixing point 401 and a fan plate fixing point 402 by respective fasteners. The fasteners may be rivets, screws, or other types of fasteners that allow the short arm 400 to pivot relative to the carriage 500 and the sector plate 200. The short arm 400 is substantially flat and elongated. The short arm 400 has a smaller length than the long arm 300. The width of the short arm 400 may be less than or equal to the width of the bezel 100. The carriage 500 has a short arm holder 510 into which the short arm can be mounted.

When the window stay is closed, the short arm 400 is positioned in the short arm holder 510 of the carriage 500. This may result in the short arm 400 being positioned substantially entirely within the footprint of the carriage 500 when viewed from the perspective of fig. 1. Similarly, the long arm 300 may be positioned entirely within the footprint of the bezel 100 when viewed from the perspective of fig. 1. The fan plate 200 is aligned with the frame plate 100 and the fan plate is partially positioned over the carriage 500 and the long arm 300. To make this possible, the frame plate fixing point 301, the fan plate fixing point 302, the carriage fixing point 410 and the fan plate fixing point 402 may be configured such that the frame plate 100, the fan plate 200 and the long arm 300 operate on different planes.

When the window stay is opened, the long and

short arms

300 and 400 pivot at their respective pivot points to move the sash plate 200 (and thus, the sash) from the frame plate 100 (and thus, the frame). This allows the window to be opened. The long arm 300 and the short arm 400 bear the weight of the sash when the window is open, and thus they are configured to support such loads. The long and

short arms

300 and 400 may be made of a relatively high strength material, such as steel or aluminum, and may have a thickness that avoids bending under load. One or both of the long arm 300 and the short arm 400 may be a reinforcing member such as a rib to provide further strength.

The sash fixation point 301 and the fan plate fixation point 302 of the long arm 300 and the carriage fixation point 401 and the fan plate fixation point 402 of the short arm 400 may be relatively high friction to keep the sash in position relative to the frame of the window without user force. For example, a force of about 5Nm may be required to overcome the friction of these fixing points to move the sash relative to the frame.

In the general mode (i.e., when the slider approaches the end 102), the fan plate 200 may be constrained to be at an acute angle to the frame plate 100. In the cleaning mode (i.e., when the carriage 500 is proximate the end 103), the fan plate 200 is in its most open position, which may be at approximately a right angle to the frame plate 100. This allows access to both sides of the window for e.g. cleaning.

The window brace shown in fig. 1 may be referred to as a four-bar window brace because there are four major bar members (i.e., the bezel 100, the fan plate 200, the long arm 300, and the short arm 400). The carriage 500 may be used in other window brace configurations as well, such as a six bar window brace.

Fig. 2 shows a view of the window stay in the direction of arrow a.

At the end 102 of the frame plate 100 (and thus at the end of the rail), the frame plate 100 has a pair of stops 131, one on one of the two long sides of the frame plate 100. Each stopper may be in the form of being pressed in the lip 130 of the frame plate 100, and the stopper 131 may be formed as a portion of the lip 130 inclined toward the carriage 500. An angle θ between the protruding direction of the lip 130 and the blocking portion 131 may be about 45 °. In some cases, the angle tends to make the barrier 131 more solid. The blocking portion may be provided only on one side of the frame plate 100.

When the carriage 500 moves toward the end 102 of the frame plate 100, the stopper 131 abuts the carriage 500. Specifically, each stop 131 may abut a respective abutment 531 of the carriage 500. This may hinder the carriage 500 from passing over the end 102 of the frame plate 100. Each abutment 531 may be a surface of the wall of the carriage defining the channel 530.

An abutment 531 is formed at an end of a recess 532 in the inner surface of the carriage 500. The recesses 532 may be shaped to accommodate the length of the barrier 131 before the barrier 131 abuts the corresponding abutment 531. In this case, when the blocking portions 131 abut the respective abutting portions 531, the end portions 102 of the frame plate 100 may be flush with the carriage 500. The depth of the recess 532 (and therefore the length of each barrier 131) may be about 5 mm. The thickness of each blocking portion 131 may be the same as that of the lip portion 130.

The stop 131 may be configured to abut the abutment 531 while the stop 120 abuts the end of the recess 520. In this way, the stop 131 and the stop 120 provide a plurality of limiters for the movement of the carriage 500 over the end 102 of the frame plate 100. In another embodiment, the barrier 131 may be positioned to abut the abutment 531 only when the barrier 120 fails. In this way, the stopper 131 acts as a candidate limiter.

Fig. 3 and 4 show the window stay in different positions of the carriage 500 with respect to the rail of the frame plate 100. For clarity, other components than the frame plate 100 and the carriage 500 are omitted in fig. 3 and 4.

In fig. 3, the carriage 500 is partially remote from the end 102 of the track. The blocking portions 131 on both sides of the frame plate 100 are aligned with the recesses 532, but outside the recesses 5. In this position, the latch 110 may hold the carriage 500 from further movement toward the end 103 of the frame plate 100.

In fig. 4, the carriage 500 is located at the end 102 of the track such that the carriage 500 is substantially flush with the end 102. The stop 131 is located within the recess 532 and abuts the abutment 531 at the end of the recess 532. This may correspond to a position where the stopper 120 pushes against the end of the recess 520.

Fig. 5 shows a partially transparent view of a portion of fig. 4. The blocking portion 131 of the frame plate 100 is located within the recess 532 and abuts the abutment portion 531 of the carriage 500. The lip 130 of the bezel 100 is positioned within the channel 530 of the carriage 500. Due to the abutment between the blocking portion 131 and the abutment 531, the carriage 500 cannot move beyond the end 102 of the frame plate 100.

In use, under strong winds, the window sash may be subjected to momentary brute forces. This force can be transferred to the carriage 500 via the short arm 400. This may in turn lead to the carriage 500 overriding the control of the stop 120, provided that no further stop is provided. This may require reassembly of the window brace or may result in permanent damage to the window brace.

However, the blocking portion 131 may inhibit the carriage 500 from moving away from the end 102 of the frame plate 100. The lip 130 is adjacent each stop 131 in the channel 530, which may further inhibit the carriage from rising above the stop 131. In this way, the window brace is more resilient and less likely to be damaged even in high wind conditions.
