Abstract
A friction stay for mounting an opening vent 5 in a surrounding frame 6 has frame plate 2 for securing to the frame 6 and a vent plate with end portions 13, 14 extending normal to each other for securing to the vent 5 on two adjoining edges at the corner of the vent 5 such that fixing screws 16 for the vent plate do not penetrate a ventilation slot 20 provided in the top rail 21 of the vent 5. <IMAGE>
Description
FRICTION STAY
This invention relates to friction stays and in particular, though not exclusively, friction stays suitable for windows.
It is well known to support an opening window vent in a surrounding frame by a pair of friction stays arranged either on opposite sides or at the top and bottom of the vent. The vent is held in any adjusted open position by the friction of the stays.
With the increased use of double glazing, the weight of the vent can be considerable even for small window sizes, and to ensure adequate fixing, the known friction stays have elongate mounting plates for securing to the vent and surrounding frame at several positions spaced apart along the length thereof.
Recent legislation requires all windows to be provided with a ventilator to ensure adequate ventilation when the vent is closed.
To meet this requirement, it is known to form a slot extending through the vent, usually in the top rail, and to mount the ventilator on the inside of the vent to control the airflow through the slot.
Where the vent is mounted in the surrounding frame by friction stays at the top and bottom of the vent, the screws used to secure the elongate mounting plate of the friction stay can pierce the slot provided in the top rail leading to inadequate fixing of the friction stay. This is a particular problem in timber windows where the provision of the slot can weaken considerably the top rail leaving very little timber for the screws to screw into to secure the elongate mounting plate of the friction stay to the vent.
The present invention has been made from a consideration of this problem.
According to the present invention there is provided a friction stay for mounting an opening vent in a surrounding frame, the stay comprising respective mounting plates for securing to the frame and vent connected by a link mechanism permitting opening movement of the vent relative to the frame characterised in that the mounting plate for securing to the vent has first and second portions extending substantially normal to each other for securing on two adjoining edges of the vent.
By securing the mounting plate on two adjoining edges of the vent, a slot can be provided in the top rail of the vent for fitting a ventilator without adversely affecting the fixing of the stay.
Other features, benefits and advantages of the invention will be understood from the following description of an exemplary embodiment wherein:
FIGURE 1 is a plan view of a friction hinge embodying the invention in an open position;
FIGURE 2 is a side view of the friction hinge in the direction of arrow A in Figure 1; and
FIGURE 3 is a side view of the friction hinge in a closed position fitted to an opening window vent.
The friction window stay 1 shown in the drawings comprises a pair of mounting plates 2,3 connected by a link mechanism 4 for supporting an opening window vent 5 in a surrounding frame 6.
The frame mounting plate 2 is of elongate channel-section with three longitudinally spaced apart holes 7 for fixing screws 8 and inwardly directed longitudinal lips 9 to retain a friction block 10 for sliding movement lengthwise of the plate 2. The frictional engagement between the block 10 and plate 2 is adjustable by means of a screw 11.
The vent mounting plate 3 is of L-shape with a bend 12 intermediate its ends connecting end portions 13 and 14 extending normal to each other.
Each end portion 13,14 has two longitudinally spaced apart holes 15 for fixing screws 16.
The link mechanism includes a first short arm 17 pivotally connected at one end to the friction block 10 and at the other end to the end portion 13 adjacent to the bend 12. A second long arm 18 is pivotally connected at one end to the frame mounting plate 3 and at the other end to the end portion 13 remote from the bend 12. A third arm 19 is pivotally connected at one to the friction block 10 and at the other end to the long arm 18 intermediate its ends.
The link mechanism 4 enables the stay 1 to fold between the open position shown in Figures 1 and 2 and the closed position shown in Figure 3.
For such folding movement, the friction block 10 is slidable along the frame mounting plate 2 and the vent mounting plate 3 is held in any adjusted position by the frictional engagement between the block 10 and the plate 2.
The friction to hold the plate 3 in any adjusted position may be assisted by using a friction pivot joint for one or more of the pivotal connections of the link mechanism 4.
In use of the stay 1 the vent mounting plate 3 is positioned at the
corner of the vent 5 with the end portions 13,14 secured on two adjoining
edges of the vent 5 and the frame mounting plate 2 is secured to the frame
opposite the end portion 13.
In this way, the screws 16 securing the vent mounting plate 3 are
confined to the corner edge region of the vent 5 enabling a ventilation
slot 20 to be provided in the top rail 21 of the vent clear off the screws 16 whilst the overall length of the vent mounting plate 3 required to support the weight of the vent 5 is maintained by the L-shape.
The above advantages are obtained for both a side hung vent 5 as shown in Figure 3 in which a pair of stays I are provided at the top and bottom of the vent and for a top hung vent in which the stays 1 are provided on opposite sides of the vent such that the end portion 14 would extend along the edge of the vent at the top and bottom.
Finally, it will be understood that the invention is not limited to the friction stay above-described. The L-shaped vent mounting plate could be used in other friction stays as will be familiar to those skilled in the art.
Claims (15)
