Abstract

A frame member for a glazed door or window has inner <B>2</B> and outer <B>4</B> aluminium sections connected by a thermally insulating web <B>6</B> which extends along the locking edge of the door and has a formation, which may be a groove <B>8</B>, for receiving a lock mounting plate <B>10</B> which supports a locking device <B>12</B>. A second thermally insulating web <B>36</B> may extend between the inner <B>2</B> and outer <B>4</B> aluminium sections.

Description

<Desc/Clms Page number 1>
Frame Members This invention relates to frame members and more particularly to thermally broken frame members suitable for fabricating windows and doors which are required to be fitted with a lock mechanism along a closing edge for locking engagement with an adjacent fixed frame.
For certain applications, glazing frames fabricated from extruded aluminium alloy glazing bars remain the preferred choice, having superior strength, stability, durability and other advantages compared with frames of pvc-U material.
A recognised disadvantage of frames fabricated from aluminium alloy bars is that, in the event of low external temperatures occurring, the good thermal conductivity of aluminium may result in the cooling of the interior-facing surfaces of the frame resulting in heat loss and also condensation, if the interior atmosphere is sufficiently warm and humid.
Many proposals have been made to mitigate this problem by introducing so called'thermally broken'designs in which the inner and outer sections of an extruded alloy frame member (which may be referred to herein as a'profile') are interconnected by means of a rigid member of heat insulating material which substantially reduces heat conduction between the inner and outer sections of the profile.
In the case of doors and windows which are intended to be fitted with a lock mechanism, such as multi-point locking espagnoilette devices, which may extend the full length of the frame, it has been difficult if not impossible to
<Desc/Clms Page number 2>
achieve an adequate U value without increasing the depth of the frame.
The insertion of a lock mechanism effectively forms a thermal bridge between the inner and outer sections of the frame.
Accordingly, if the U is to be maintained which extends a deeper frame is required to accommodate both the lock mechanism and separate conventional insulating members on each side of the mechanism.
This problem is overcome by the present invention which consists in: a thermally insulating frame member suitable for use in the construction of a glazed door or window, comprising inner and outer alloy elements interconnected by a web of thermally insulating material characterised in that the insulating web has a longitudinally extending formation which is adapted to receive and locate a lock mechanism along an edge of the frame, the mechanism including a lock mounting member, and one or more bolt members adapted to retractably project through apertures in the lock mounting member and actuating means operable from at least one side of the frame for causing each bolt member to retractably project into locking engagement with keep members provided on an adjacent frame member.
<Desc/Clms Page number 3>
Preferably, the longitudinally extending formation is an outwardly opening groove, adapted to locate and receive the said lock mounting member.
Retaining means may be provided to retain the lock mounting member in the groove member.
The insulating web preferably has a channel section for at least partially accommodating the bolt member or members.
The web is preferably formed as a plastics extrusion of an suitable material such as polyamide.
The web may have formations along the inner and outer edge portions, which are adapted to be retained by complimentary formations provided along the respective adjacent inner and outer alloy sections.
Preferably, the formations and complimentary formations are adapted to be inter-engaged by a rolling process.
A locking door frame or window frame which incorporates a frame member as claimed in any preceding Claim is thinner and lighter than a conventionally constructed unit of the same frame U value.
<Desc/Clms Page number 4>
This invention will now be described by way of example only with reference to the accompanying drawing which shows a cross section of the edge of an door frame and the adjacent edge of a fixed frame or door jamb.
The locking edge of a door frame has inner and outer alloy sections 2,4 interconnected along the locking edge by an extruded polyamide web 6 which forms a continuous thermal break between the inner and outer sections 2,4 to provide a specified U value.
A rebate or groove 8 (also referred to a'Eurogroove') is provided to receive and locate the lock mounting member 10 which constitutes part of an industry-recognised 'Eurogroove' lock having form of espagnolette lock mechanism 12.
Although no formal standards exist,'so called'Eurogroove' locks of different manufacturing origin are all intended to be interchangeable and should fit into standardised grooves and cavities formed to receive them in at the closing edges of industrially produced door and window products.
Apertures are provided along the lock member through which bolts such as 16 may retractably project (by means not shown) into locking engagement with a keep 18 located on the jamb 20 The main body 14 of the lock 12 which forms no part of this invention, is supported between the inner and outer sections 2,
<Desc/Clms Page number 5>
4, whereas the retractable bolt mechanism is accommodated within a channel formation 22.
Web 6 is rigidly interconnected between inner and outer sections 2,4 by means of complimentary inter-engaged formations 24,26 which are rolled together to give an interference fit and further by means of bracing webs 28 which abut the opposed surfaces of sections 2,4 to enhance rigidity further.
The opposite edge of the frame optionally may be adapted to receive the edge of a glazing panel, not shown, in rebate 30 and retained therein by means including a glazing bead 32 and glazing gasket 34. A second web 36 of thermally insulating material is provided interconnecting the inner and outer sections. A preferred arrangement, illustrated, is more fully described in our co-pending UK Patent Application No. 0117104. 0 entitled Secure Window Units and need not be described further.

Claims (10)

  1. What we claim is :- 1.

  2. 2. A frame member as claimed in Claim 1 in which the web is formed with an outwardly opening groove, which is adapted to receive the said lock mounting member.
  3. 3. A frame member as claimed in Claim 2 in which retaining means are provided to retain the lock mounting member in the groove member.
    <Desc/Clms Page number 7>
  4. 4. A frame member as claimed in Claim 1, 2 or 3 in which the web has a channel section for at least partially accommodating the bolt members
  5. 5. A frame member as claimed in any preceding Claim in which the web is formed as a plastics extrusion.
  6. 6. A frame member as claimed in Claim 5 in which the web has formations along the inner and outer edge portions which are adapted to be retained by complimentary formations provided along the respective adjacent inner and outer alloy sections.
  7. 7. A frame member as claimed in Claim 6 in which the formations and complimentary formations are adapted to be inter-engaged by a rolling process.
  8. 8. A door frame or window frame which incorporates a frame member as claimed in any preceding Claim
  9. 9. A door frame or window frame as claimed in Claim 8 in which the opposite side of the frame incorporates a
    <Desc/Clms Page number 8>
    thermally insulating web extending between the inner and outer sections of the frame.
