Abstract
A pivot bracket for use in support of an outwardly opening window comprises an elongate mounting member (10), for securement to the inside of a window frame, an elongate support member (11) for attachment to an edge of a window, and two arms (12, 13) pivoted at opposite ends to the two members. The members (10) (11) having means (24) (25) for holding them in the closed position. The axes of the pivot connections (16, 18) to the mounting member (10) are further apart than the axes of the pivot connections (20, 22) to the support member (11) to provide a swinging movement to the window during opening whereby both sides of the window can be cleaned from inside the window frame. The geometry is such as to provide a self-locking action when the window is closed. <IMAGE>
Description
SPECIFICATION
A pivot bracket for supporting an outwardly-opening window casement
This invention relates to a pivot bracket for use in the support of an outwardly-opening window casement or the like where, in the open position, a gap for cleaning exists between the pivot side of the casement and the fixed window frame.
While pivot brackets for such windows have been proposed in the past, for example as shown in U.S. Patent Specification No. 2,784,459 and German Auslegeschrift No. 2,237,669, these have generally not been suitable for use with heavy window casements with an installation rebate of, for example, only 20 mm deep and 13 mm high. These prior constructions generally are cumbersome with, for example, a slide mechanism which renders them unsuitable for use with larger and heavier window casements.
According to the present invention there is provided a pivot bracket for use in the support of an outwardly-opening window casement, such bracket comprising an elongate mounting member for securement to the inside of a window frame, an elongate support member for mounting an edge of a window, and two arms each pivotably connected to both said members, one arm being shorter than the other with the axes of the pivotable connections to the mounting member being further apart than the axes of the pivotable connections to the support member, interengaging means being provided at those ends of the members nearer the short arm for holding the members in an aligned closed position. Preferably these interengaging means are so located that they cause the arms to be under compression in the closed position of the window so as to provide a force holding the window in its closed position.Preferably the pivot axes are so relatively arranged as to provide an overcentering action to hold a window closed in use of the brackets. Conveniently the interengaging means may comprise flanges provided at the cooperating ends of the two members, these flanges extending in planes perpendicular to the planes of the members and being inclined to the longitudinal axis of the members so as to provide a detent action. Both flanges may, although not necessarily, be equally inclined to the longitudinal extent of the respective members.
In an alternative embodiment an anti-friction means in the form of, for example, a roller may be provided on one of the members, preferably the support member, for engagement with the flange comprising the interengaging means of the mounting member. Such anti-friction means helps to resist wear of the interengaging means during use of the window over an extended period of years.
The invention will be described by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a side elevational view of a pivot bracket in accordance with the invention shown in a partly open condition;
Figure 2 illustrates the bracket of Figure 1 in a
closed condition;
Figure 3 shows the pivot bracket of Figure 1 in a
fully open position;
Figure 4 is a detail elevational view showing part
of a modified embodiment of the invention;
Figure 5 is a plan view of the showing of Figure 4; and
Figure 6 is a view similar to Figure 1 showing a
modified embodiment of the invention.
Figure 1 shows a pivot bracket comprising a
mounting member (10) for securement to the inside of a window frame by fasteners extending through fastening apertures (32) (Figure 3). An elongate support member (11) is provided with apertures (35) to connect it to the window casement and is connected to the mounting bracket (10) by means of two arms (12) and (13) of unequal length.
The longer (12) of these arms has one end pivotably connected at (18) to the mounting bracket (10) and the other end pivotably connected at (20) to the support member. The shorter arm (13) has one end connected by pivot (16) to the mounting member (10) and the other end pivotably secured at (22) to the support member (11). Slight cranks (38) and (37) are provided in the elongate arms (12) and (13) in order to permit the outer end of the arm (12) to overlie the arm (13) in the closed position of the bracket as shown in Figure 2.
Interengaging means are provided on the ends of the mounting and support members nearer the shorter arm (13) to hold the window in its closed position in use of the pivot bracket. These interengaging means comprise flanges (24) and (25) provided on the members (10) and (11) respectively.
Both these flanges extend generally at right angles to the plane of the members and are inclined relative to the longitudinal extent of the members to provide a detent action to resist outward-opening movement of the pivot bracket. While in Figure 2 these flanges are shown as being differently inclined, preferably they are inclined by equal amounts to the longitudinal extent of their respective members as shown in the embodiment of Figure 10 where equally inclined flanges (40) and (42) are shown on the respective mounting and support members (10) and (11).
Figure 4 shows a modified embodiment in which instead of the flange (25) a roller (25') is shown for engagement with the flange (24). The arrangement of this roller for engagement with the flange can also be appreciated from the plan view of Figure 5.
The provision of this roller is to avoid wear on the interengaging means bearing in mind that they will engage with some force in that in the preferred construction, in the closed position of the bracket, the arms (12) and (13) will be under compression.
The pivots (16), (18), (20) and (22) are so locted as to provide an overcentering action at the last part of closing movement of the pivot bracket.
Thus it will be noted that the pivot (18) is nearer the open side of the window than the pivot (16) so that upon movement of the pivot bracket from the closed position shown in Figure 2 initially the axis of the pivot (20) will need to have a small upward component of movement to increase the compression in the arms (12) and (13) prior to the window opening easily to the fully open position shown in
Figure 3.
A stop (30) is provided as means to limit opening movement of the pivot bracket. This top limits pivotal movement of the shorter arm (13) in a window-opening direction.
