Abstract

A vertically sliding sash window is hinged to a guide rail 4, 5 via a hinge (12, Fig 3) connected to a guide plate (11, Fig 3) which can slide along a slot or groove (10, Fig 3); the opposite side of the sash is releasably connected to its adjacent guide rail by spring biased catches (13, Fig 3) so that the sash can be swung into a room for cleaning. <IMAGE>

Description

SASH WINDOW The invention relates to a vertically sliding window and in particular to one arranged so that it is particularly simple and safe to clean opposite sides of the sash windows.

According to the invention in one aspect there is provided a vertical sliding window comprising a guide frame having two side vertical guide rails, a top sash and a bottom sash, each sash having at one side means for moving that sash vertically in the frame, the moving means being present in the adjacent guide rail, the sash being hinged to the guide rail associated with the moving means therefor by hinge means arranged to pivot the sash with respect to the frame about the respective rail, the opposite side of each sash being releasably engaged with--the adjacent guide rail.

In order that the invention may be well understood it will now be described by way of example only with reference to the accompanying diagrammatic drawings, in which: Figure 1 is a front inside elevation of the vertically sliding window, having an upper sash and bottom sash; Figure 2 is a plan view showing the window of Figure 1 with both sashes in the cleaning position; Figure 3 is a partial transverse sectional view through the vertical stiles of the window frame of Figure 1, and Figure 4 is a partial vertical sectional view of one of the stiles of Figure 3.

The window includes an outer frame 1 comprising a cill 2, a head 3, a left hand guide rail or pulley stile 4 and a right hand guide rail or pulley stile 5. The frame contains a bottom or inner sash B, comprising a bottom rail B1, a top rail B2, a left hand stile B3 and a right hand stile B4, together with an upper or outer sash U comprising a bottom rail U1, a top rail U2, and left and right hand stiles U3, U4 respectively. The sashes B and U contain a glass pane or a sealed glass unit G, together with the usual glazing beads etc. As will be explained below, each sash is arranged for vertical movement within the outer frame 1 in the usual way, but in addition is hinged so that it may be pivoted to extend into a room, and to the condition shown in Figure 2 allowing both sides of the sash to be cleaned without the need for the cleaner to lean over or otherwise reach outside the building.Each sash is hinged on a different pulley stile.

Each pulley stile is of the same structure but of the opposite hand. For convenience the structure will be described with reference to the right hand stile 5 shown in Figure 3. The stile has two parallel vertical slots 6, 7 each being of generally T shape. The upper slot 6 as shown in Figure 3, has a main slot part 8, containing a sash spring 9 incorporating a balance and a front slot or groove 10 containing a guide plate 11 which faces the stile of the sash. A hinge 12 is present at the top and bottom of the stile facing the slot 6, one hinge plate 12a of each hinge being screwed into the stile of the sash and the other hinge plate 12b being screwed into the adjacent wall of the guide plate 11. The lower slot 7 is empty to receive a spring biased guide block or catch 13 mounted in a slot 14 in the facing wall of the other sash.Two catches 13 are present, one at the top and the other at the bottom of the sash stile. It will be clear that once the guide block 13 is released from its facing slot 7 the sash is free to pivot about the hinge on the opposite stile to the condition shown in Figure 2.

The sashes are used in the usual way, i.e. to slide the bottom sash B vertically, the bottom rail is gripped and,the sash is moved up or down. The upper sash U is operated in the same way, gripping the top rail U1. To open the bottom sash B for cleaning, the sash is pulled upwards to a position about 150 mm from its lowest point and the lower catch is withdrawn by sliding from the slot 7. The sash is lowered to its lowest point and the same procedure is repeated with the other catch. The sash is then free of the adjacent stile and can be rotated about its hinges mounted on the other stile. The sash can then be cleaned while within the room, and it is easy to gain access to both sides of the glass. The sash is returned to the frame until the catches 13 and engaged with the respective slots 7.

Claims
