This invention relates to sashes for mounting in a door
or window frame and is applicable both to ~ashes comprising a
single transparent pane and a plurality of generally parallel
transparent panes.
It-is well known to mount a pane or panes using rigid
elongate members in contact with a least one side of said pane
or panes and which may form a ~ater-tight seal with a frame
surrounding the pane or panes. However all the systems
suggested so far are complicated to put into practice. In ~act
their mounting requires many hours of work because it requires
use of mastic, positioning of air-tight joints and marking,
positioning and adjustment of pieces connected to the frame, such
as hinges, locks, bolts, casement bolts, handles, candlestic~
holders and the like.
In order to avoid at least some of these disadvantages
it has been suggested to provide the rigid elongate member, on
at least one of its sides, with external fixing members and
particularly a slide of V-shaped section with a narrow gap be-
tween the branches placed at the edge of the frame and allowing
mounting of the latter in any manner by means of members
inserted in the groove; advantageously this slide extends
around the four sides of a rectangular pane. The manufacturer
can thus produce a large number of identical units in an unin-
terrupted productio~ area and these units are suitable for a
large number of different applications allowing a major reduction
in stocks which have to be held.
According to one aspect of the invention there is provided
a sash for mounting in a door or window frame so as to be
pivotally movable relative to the frame, said sash including one
or more transparent panes each having edges,
an elastic sealing member attached to and extending along
the edges of the pane or panes,

a rigid elongate member located at least partially within
the elastic member and having a slideway,
members for pivotally mounting the sash located in said
slideway,
said members for pivotally molmting the sash being slidably
displaceable along the slideway and fixable at a desired position
along the slidewayj each member for pivotally mounting the sash
defining a pivot axis about which the sash is pivotally movable.
Preferably the elastic sealing member or seal surrounds
the periphery of the pane and, in the case of a plurality of
panes, it forms at the same time a joining member for the panes
and an internal seal; such a joining member may be waterproof
and formed of composite layers. Advantageously the elastic seal
may form a seal between the panes and an outer frame in which
it is mounted in use.
~he rigid elongate member may be composed of elements,such
' as rectilinear sections, with or without angle members, obtained
- for example by moulding but it may also surround completely the
periphery of the pane.
Parts of the rigid elongate member within the sealing
member may abut the faces of the panes.
Alternatively, the rigid elongate member may be joined to
a longitudinal separating member between the panes and/or an
~ngle member separating the panes at a corner of the panes.
In one preferred embodiment the elastic seal is formed
of an elastomer such as polyethylene tetrasulphide and the rigid
elongate member is formed of a metal or rigid plastics material
~uch as polyvinylchloride or reinforced polyester; the elastic
seal may be extruded on to the rigid elongate member which
facilitates automatic manufacture. The elements, i.e. the pane
or panes and spacers, may be applied after extrusion and before
polymerisation.

In another advantageous embodiment the rigid elongate
member and the elastic seal are made in a single soft-on-hard
extrusion operation carried out directly on to the pane or panes;
they may however be obtained from the same base composition.
~ mbodiments of the invention will be described by way
of ~xample with reference to the accompanying drawings,
in which,

according to the invention comprising two panes,

~ ig. 3 is a partly cut away perspective view of the
window sash o~ Figs. 1 and 2,

of mounting connecting pieces between the sash and an outer

of mounting of the connecting pieces between the panes and an
outer frame (not shown) for an opening about a horizontal axis,
Fig. 6 is a view from above in section representing a
French window.
As shown in Figures 1, 2 and 3, the sash is formed by
two panes or sheets of glass 1 and 2 maintained a certain
distance one from the other by hollow elongate members 3 in such
a manner as to form between the two sheets a space 4. ~he hollow
elonga*e members 3 are mounted at the four corners of the unit
in known manner by the angle members 5, members 3 containing a
dehydrating substance so as to avoid condensation of water vapour
in the space 4 between the two sheets after the unit is sealed.
If the unit is not sealed, so that the space is in communication
with the external atmosphere, no dehydrating substance is necessary.
~he sheets 1 and 2 are connected and held together by an elongate
elastic sealing member 6, in this case of rubber or an elastic
plastics material such as a polysulphide, moulded or extruded on
., ,

the four sides of the pane. This elongate member 6 comprises
lips 6', 6" and 6" ' intended to be squeezed against the outer
frame in order to e~sure air-tight sealing. Within this elongate
member 6 there is mounted a rigid elongate member 7 having a
slideway in the form of a groove of dove-tail cross-section.
The groove may also be of ~ or other desired shape.
This rigid elongate member may be made o~ metal or a rigid
plastics material such as PVC or reinforced polyester. This
rigid elongate member is connected solidly to the angle members 5
by screws 8, screwed into the members 5, the penetration of the
screws 8 not being shown. This type of connection, although it
is used in the embodiment of ~igures 1 to 3 to give an increase
in strength, is not indispensable; it is possible to form the
elongate member 3 intended to maintain the two sheets 1 and 2 at
a certain distance from each other, of the same material, integral
with and at the same time as the elongate member 6. It is also
possible to make integrally the rigid slongate member 7 and the
elongate members 6 and 3 of the same plastics material in a
soft-on-hard extrusion operation which may be carried out directly
on the panes. In the latter case the lips 6' and 6" are flexible
whereas the corresponding parts of the elongate member 3 are
relatively more rigid and that corresponding to the rigid elongate
member 7 will give a maximum rigidity.
~ onversely the member 3 may be replaced in known manner by
a plastics channel member which is not impervious to water vapour,
containing the desiccant material.
In ~igures 4 and 5 is shown in perspective a method of
mounting the connection pieces between the panes and the outer
frame allowing opening o~ the mounted window sash by rotation about
different axes. ~he hinges or hinge parts 9 and 10 comprise a
male dove-tail part 11 and 12 engaging in-the rigid elongate
member 7 of which the dove-tail is rebated at the angles of the
frame.
1~4783~
Two screws 13 or 14 allow fixing of the connection
piece 9 or 10 at an~ required position.
It should also be noted that t;he external part of the
member 6 could be considerably reduced~ framing of the panes
thus being assured by the V-shaped elements covering the edges
of the panes and provided with openings for passage of hinges or
hinge parts 9 and 10 or other fittings.
In ~igure 6 is shown in view from above and in section,
a ~rench window formed by two window sashes 15 and 16. This
embodiment illustrates clearly the universality of the system;
in fact the two window sashes 15 and 16 are mounted on vertical
mountings 17 and 18 by hinges 19 and 20 held in the rigid elongate
member 7 of the elongate member 6 by male dove-tail pieces held
in place by the screw 21. At the edge of the window sash 15
- opposed to the hinges the window sash is provided with a casement
bolt closing system 22 comprising a handle 23 and a vertical
closing slider 24 activated by the handle 23.
This casement bolt closing is maintained in the rigid
elongate member 7 of the pane by male dove-tail pieces 25 held
by screws 26. ~he pane 16, for its part, is provided at its
edge opposed to the h~geS 20 with a member 27 of ~-shape i~tended
to ensure water-tightness between the two window sashes 15 and 16.
~his ~-shaped piece 27 is also mounted in the rigid elongate
member 7 of the window sash 16 by dove-tail male members 28 held
by the screws 29.
The flexible lips 6', 6" and 6"' of the rigid elongate
member 7 ensure water-tightness in the mPnner described above.
It will be appreciated that the above-described sashes,
apart from ease of manufacture owing to the construction of the
elastic sealing member and ease of mounting owing to the rigid
elongate member, have good sound insulation.properties because
of the elasticity of the lips of the elastic sealing member.
