Description
TITLE: RELEASABLE JOINT
Field of the Invention
The present invention relates to a releasable joint and method of achieving the
same. The joint is particularly suited for joining elongate extruded members such as
aluminium window elements and the like and will be described hereinafter with
reference to this use. However, it will be appreciated that the invention is not limited to
this particular application and can be adapted to provide a simple means for releasably
joining any pair of suitably configured elements.
Description of the Prior Art
It is often necessary for aluminium window frame elements to be constructed from
two or more separate sections. In some cases this arises due to a desire to rationalise
stock elements, whereby special sections are constructed in a modular fashion from more
standard common sections. In other cases the multi-part design arises from a need to
enable on-site assembly whereby intermediate members such as window or door sashes
must first be installed within the outer frame before the final element ofthe window or
door frame is secured thereto.
An example ofthe latter case is in sliding door and window structures, where it is
often necessary or desirable to attach an outer guide rail to the frame only after the inner
window or door assembly has been hung. Such a connection needs to be releasable to
enable dismantling of the window structure for repair. In the past this connection of
separate elements has been achieved using conventional mechanical fasteners and the
like. These fixing methods come with several associated disadvantages such as the need
to provide holes in the extruded elements either during or prior to assembly. Also, such
mechanical fasteners are often unsightly and unless special steps are taken the joints are
not weatherproof and can be prone to vibration, all of which can become worse with
wear. Further, it is often difficult to dismantle the joint due, for example, to the need for
specialist tools and corrosion ofthe fasteners etc.
It is an object ofthe present invention to provide a releasable joint and method of
achieving the same that overcomes or ameliorates one or more ofthe above discussed
disadvantages ofthe prior art or at least offers a useful alternative thereto.
Disclosure ofthe Invention
According to a first aspect ofthe invention there is provided a releasable joint
including:
a first member having an elongate generally T-sectioned connecting formation
defining opposing securing flanges;
a second member having a corresponding generally elongate undercut channel in a
surface thereof defining, at the edge of said channel, two opposing retaining
protuberances, said connecting formation and undercut channel being configured such
that said channel is adapted to: (i) receive therein from a direction generally transverse to
the plane of said surface the generally T-sectioned connecting formation ofthe first
member; and (ii) permit subsequent displacement ofthe connecting formation within the
undercut channel into a locking position wherein removal thereof in a direction
transverse to said surface is prevented by said retaining protuberances and whereby in
said locking position a receiving groove is simultaneously defined along an edge of said
channel immediately adjacent one of said securing flanges; and
an elongate resilient beading element;
said resilient beading element being captively retained upon insertion into said
receiving groove so as to urge and maintain said connecting formation in the locking
position within the undercut channel.
According to a second aspect ofthe invention there is provided a method of
making a joint between first and second members wherein said first member has an
elongate generally T-sectioned connecting formation defining opposing securing flanges,
and said second member has a corresponding generally elongate undercut channel in a
surface thereof, wherein said connecting formation and undercut channel are configured
such that said channel is adapted to: (i) receive therein from a direction generally
transverse to the plane of said surface the generally T-sectioned connecting formation of
the first member; and (ii) permit subsequent displacement ofthe connecting formation
within the undercut channel into a locking position wherein removal thereof in a
direction transverse to said surface is prevented and whereby a receiving groove is
simultaneously defined along an edge of said cavity immediately adjacent one of said
securing flanges, said method including the steps of:
inserting the T-sectioned connecting formation ofthe first member into the
undercut channel ofthe second member in a direction that is generally transverse to said
surface;
displacing said connecting formation within the undercut channel into the locking
position thereby simultaneously defining a receiving groove along an edge of said
channel immediately adjacent one of said securing flanges; and
inserting into said receiving groove an elongate resilient beading element so as to
urge and maintain said connecting formation in the locking position to thereby secure the
joint.
It should be noted that the term T-sectioned connecting formation is used herein to
define any structure that defines opposed securing flanges that extend upon assembly in
a direction generally parallel to said surface in which the undercut channel is provided,
so as to be operable within the bounds ofthe claim defined above. Similarly, reference
to insertion ofthe T-sectioned connecting formation in a direction generally transverse to
said surface is intended to include within it's scope part rotational and /or part
translational movements.
In a preferred form ofthe invention the T-sectioned connecting formation ofthe
first member has a first long retaining flange and a second shorter retaining flange. The
corresponding undercut channel in the second part similarly defines two opposed first
and second retaining protuberances having a cavity therebehind, the protuberances being
spaced to allow insertion and subsequent movement ofthe T-sectioned formation therein
as described above, such that upon movement ofthe connecting formation to the locking
position a receiving channel is defined intermediate the first retaining flange and first
protuberance sized to captively retain therein an elongate resilient beading element
which retains the joint.
In one preferred form the generally T-sectioned connecting formation is configured
to enable insertion into the undercut channel, one ofthe securing flanges, that is
preferably the first longer securing flange, needs to be hooked as far as possible under
the first of said protuberances after which the remaining portion ofthe connecting
formation including the second securing flange can be rotated into position in the
undercut channel. The entire connecting formation is then moved across the channel
such that the second securing flange is then retained behind the second protuberance.
Due to the sizing ofthe interacting components this then results in the first longer
securing flange still being retained behind the first protuberance whilst also defining an
undercut receiving groove intermediate the first retaining flange and first protuberance.
The beading element can comprise any resilient material which includes, but is not
limited to, rubber and polymeric compounds as well as sheathed or unsheathed coil
spring type structures made of metal or polymeric materials. In one particularly
preferred form, the resilient material is an ultra violet light resistant neoprene rubber.
The beading element can be inserted into the receiving channel by any suitable means,
including use of a suitably profiled offset wheel device that progressively urges the
beading into position by rolling it into the groove.
It will be appreciated that the resilient beading element is removable thereby
making the joint releasable without damage to the members themselves as may happen
when fasteners such as rivets or screws are used. Further, the resilient qualities ofthe
beading also act to suppress vibration and depending on the material selected can also
assist to exclude draughts and inclement weather.
Brief Description of the Drawings
A preferred example of the invention will now be described, by way of example
only, with reference to the accompanying drawings in which:
Figure 1 is a sectional view a first embodiment joint in accordance with the
invention showing step one ofthe assembly process;
Figure 2 is a sectional view of the joint of Figure 1 showing steps two and three of
the assembly process; and
Figure 3 is a perspective view ofthe assembled joint ofthe previous Figures.
Modes for Carrying Out the Invention
Referring to the drawings there is illustrated a first embodiment releasable joint
according to the invention shown generally at 1. The joint includes a first member 2
having a generally T-sectioned elongate connecting formation 3 defining opposed first
and second securing flanges 4 and 5 respectively.
The second part of the joint includes a second member 6 having in it's outer surface 7 a generally elongate undercut channel 8. The channel has at its outer edges
two opposed retaining protuberances 9 and 10 respectively, behind which is a cavity 11
which is sized to receive the connecting formation 3 ofthe first member.
Referring next in particular to Figure 1, it can be seen that to assemble the joint 1, the T-sectioned connecting formation 3 ofthe first member is presented to the undercut
channel 8 from a direction generally transverse to the surface 7 ofthe second member 6.
The longer first securing flange 4 is then hooked under the first protuberance 9 ofthe
channel 8 as far as it will go, such that the remaining portion ofthe connecting formation can then be rotated into the channel. The first member is then moved transversely within
the channel until the second securing flange 5 is located beneath the second protuberance
10 ofthe channel 8. This position is referred to as the locking position as the first
securing flange, by virtue of its length, is still located behind the first retaining
protuberance 9.
In this locking position, an undercut receiving groove 12 is defined intermediate
the first flange 4 ofthe first member and the first protuberance 9 ofthe channel 8. A
resilient beading element 13 is then captively inserted into the receiving groove to secure
the joint. The insertion can be achieved by any suitable method including the use of an
offset rolling wheel device, the latter device being particularly useful for fast non- damaging insertion of beading over longer lengths.
As discussed previously the beading element can comprise any resilient material
which includes, but is not limited to, rubber and polymeric compounds as well as
sheathed or unsheathed coil spring type structures made of metal or polymeric materials.
It will also be appreciated that the resilient beading element is removable thereby
making the joint releasable without damage to the members themselves as may happen
when fasteners such as rivets or screws are used. Further, the resilient qualities ofthe
beading also act to suppress vibration and depending on the material selected can also
assist to exclude draughts and inclement weather. The end result is a joint which: requires no prior drilling or machining of any
kind; which with the use of an appropriate material for the beading element can also
eliminate or minimise vibration and a provide a weatherproof seal; and which is readily
releasable without the use of specialist tools or particularly skilled tradesmen.
It will be appreciated by those skilled in the art that the potential applications of
this joint according to the invention are endless and are clearly not limited to the
examples described in detail above.
