(54) IMPROVEMENTS RELATING TO SEALS FOR JOINTS BETWEEN
ADJOINING PANEL MEMBERS
(71) We, SOUTH LONDON ELECTRICAL EQUIPMENT COMPANY LIMITED, a Company incorporated under the laws of Great Britain,
of Lanier Works, Hither Green Lane,
London, S.F. 1.3 do hereby declare the inven
tion, for which we pray that a patent may be
granted to us, and the method by which it is
to be. performed,. to be particularly described
in and by the following statement:- This invention relates to a self-locating
seal, particularly but not exclusively for
environmental areas and so-called «clean
rooms» and is particularly concerned with
providing joints between adjoining panel
members, such as wall panels and/or ceiling
units or panels.In such areas or rooms,
the interior- must be hermetically sealed
and in addition should be free from the
generation or formulation of particulate
matter. The provision of seals for use in
constructions consisting of specially designed
wall panelling and ceiling modules which
produce an efficient seal between adjoining
interfaces is an exacting and costly procedure.
The present invention seeks to provide an
effective seal in a simpler and cheaper
manner, and according to the invention
there is provided a self-locating seal for a
joint between two adjoining panel members,
the seal being adapted to accommodate
manufacturing and/or assembly tolerances,
the seal being an elongate member of uniform
cross-section having, in cross section a central,
web comprising a centre base portion and
two side webs extending, in the unstressed
state, from the edges of the centre portion
generally towards the centre thereof to define
a channel section, a respective lateral exten
sion extending at an angle from each of
the side webs in a direction away from the
free edge of the respective side web.
Preferably, the seal is made from a syn
thetic plastics material such as polyvinyl
chloride and is, for example, an extrusion.
The free edges of the lateral extensions are
preferably knife-edged and, in effect, are self sealing.
Two embodiments of the seal and their application will now be described by way of example with reference to drawings in which:
Figure 1 shows a cross-sectional view of a first embodiment, and
Figure 2 shows a cross-section through a second embodiment applied to a different construction.
In the first embodiment shown in Figure 1 the seal is designed to be applied to the joint between a planar surface and a further panel at right angles thereto, or between two co-planar surfaces, such as two adjoining ceiling or wall panels and a further panel such as a wall located at right-angles between the two co-planar surfaces.
The seal is an elongate member formed of a polyvinyl chloride extrusion having a central web 1 extending in the installed condition, along the joint line between the three panels The centre web has a base portion 2 and side webs 3 extending therefrom so as to form a channel section which, in use, fit over the edge of a wall panel 5. In the free state of the seal the free edges 4 of the side webs are curved inwardly to the position shown in dotted lines at references 41, the natural resilience of the material enabling the seal to be slipped onto the wall panel 5 and to be held in position.
Lateral extensions 7 extend at an acute angle from the side webs 3 in the direction away from the free edge 4 of the respective side web 3. In their free, unstressed, position the lateral extensions extend generally inwardly as shown in dotted line at reference 71
In the installed position the extensions 7 are resiliently urged to the position shown in solid lines so as to bear against ceiling panels 6.
Two spaced lips 8 extend along the central web 2 to provide a further seal.
In use, the seal is applied over the edge of the wall panel 5 so that the side webs 3 lie against adjacent opposed faces of the panel, with the lateral extensions 7 directed away from the edge of the panel 5. When the panel 5 is assembled to the ceiling, or to adjoining wall panels or frame 6, the two extensions 7 are deflected outwards to provide a smooth seal and fillet along each side of the joint line, free of any dust traps or ledges.
In the second embodiment of the sealing strip shown in Figure 2 the seal is applied to the joint between two ceiling panels 6 resting on horizontal flanges 9a of a ceiling beam 9. As can be seen the base position 2 is applied to the exposed face of the beam 9 and the two side webs 3 embrace the edges of the flange. The lateral extensions 7 rest by their knife-edges against the ceiling panels 6 to form an air-tight and dust-preventing seal.
This embodiment can equally be used for the joint between two wall panels secured to a vertical flange. An additional seal is provided by lips 10 formed on the faces of the side webs 3 that abut the ceiling panels 6.
The seal of this invention avoids the use of any mastic or other sealant and renders the currently used foam-sealing techniques unnecessary.
WHAT WE CLAIM IS 1. A self-locating seal for a joint between two adjoining panel members, the seal being adapted to accommodate manufacturing and/or assembly tolerances, the seal being an elongate member of uniform cross-section having, in cross section, a central web comprising a centre base portion and two side webs extending, in the unstressed state, from the edges of the centre portion generally towards the centre thereof to define a channel section, a respective lateral extension extending at an angle from each of the side webs in a direction away from the free edge of the respective side web.
2. A seal as claimed in claim 1 wherein the free edges of the lateral extensions are knife-edged.
3. A seal as claimed in claim 1 or 2 wherein the lateral extensions extend from respective points on the respective side webs adjacent the centre base portion.
4. A seal as claimed in claim 1, 2 or 3 wherein the lateral extensions each extend from respective points intermediate the length of the respective side web.
5. A seal as claimed in any one of claims 1 to 4 wherein the seal is made of a synthetic plastics material.
6. A seal as claimed in claim 5 wherein the seal is made of polyvinylchloride.
7. A seal as claimed in any one of claims 1 to 6 wherein the seal is formed by an extrusion process.
8. A seal for a joint between two adjoining panel members substantially as described herein with reference to, and as illustrated in,
Figure 1 or Figure 2 of the accompanying drawings.

5 is assembled to the ceiling, or to adjoining wall panels or frame 6, the two extensions 7 are deflected outwards to provide a smooth seal and fillet along each side of the joint line, free of any dust traps or ledges.
In the second embodiment of the sealing strip shown in Figure 2 the seal is applied to the joint between two ceiling panels 6 resting on horizontal flanges 9a of a ceiling beam 9. As can be seen the base position 2 is applied to the exposed face of the beam 9 and the two side webs 3 embrace the edges of the flange. The lateral extensions 7 rest by their knife-edges against the ceiling panels 6 to form an air-tight and dust-preventing seal.
This embodiment can equally be used for the joint between two wall panels secured to a vertical flange. An additional seal is provided by lips 10 formed on the faces of the side webs 3 that abut the ceiling panels 6.
