MECANISME DE PORTE A PANNEAUX MULTIPLES AVEC PROPRIETES D'ISOLATION RENFORCEES

MECHANISM FOR THE OPERATION OF MULTIPLE PANELS DOOR WITH INCREASED INSULATING PROPERTIES

Abrégé français

Un mécanisme amélioré destiné à actionner une porte à multiples panneaux aux propriétés d'isolation accrues inclut un moyen d'éloigner les panneaux du joint d'étanchéité pendant leur course verticale et d'appuyer les panneaux fermement contre le joint d'étanchéité lorsque ceux-ci parviennent à la fin de leur course verticale. Les antériorités montrent une porte à panneaux multiples qui suit les rails de guidage jusqu'à ce que lesdits panneaux parviennent à la fin de leur course le long de ces rails de guidage, s'éloignant alors de ces derniers pour aller s'appuyer contre l'encadrement de porte et exercer une pression sur une bande isolante.

Abrégé anglais

An improved mechanism for the operation of multiple panels door with increased insulating properties comprises a means that keeps the door panels away from the seal as they move up or down vertically and that brings the panels tightly against the seal when the panels have completed their vertical course. In the prior art, a multiple panel door follows the path of the guide rail where in this instant invention, when the panels have run their course along the path of the guide rails, they are moved away from the guide rails and against the door frame, which results in the door panels to apply pressure against an insulating strip.

provides for better insulating properties.
L3ACKGROUIND AP THE INVENT1pN
[0021 Vertically opening doors having multipfe panels are mostly known for
their use as car garage doors although they can be used for other
applications. Over the years steel, aluminum or vinyl covered doors with
an insuiating core have been developped to increase insulating
properties. No matter the insulating properties of the core, there remains
heat loss due to the poor sealing characteristics of the perimeter seal
1.5 which atlows air to circulate. The problem is not so rnuch that the seal
is
poor, it is because the constant friction of the door opening and closing
against the seal makes it less efficient, plus the fact that, to begin with,
in order not to cause to much of a hindrance to the operation of the
door, the seal cannot create too much fric4ion against the door so that it
can open or ctose relatively effort free so as not to over work the motor

OETAILED DESCRIPTION
[0018] A mechanism for the operation of multiple panels door (10) works in
conjunation rn+ith a pair of guide rails (12) (only one shown in dattQd lines
in figs.l ab) as are commonly used in the art. The guide rails(12) do not
require any special modifications except that they are set back from a
door frame (14) in a distance greater than is usually used in the art. It is
a tso recommended that the guide rails (12) have additional bracing (not
shown) so that they can sustain more stress than normai in the arrt.

10019j The door panels (16) are also vuell known in the art and standard off
the
shelf panels (16) can be used in conjunction vvitli standard off the shelf
guide rails (12), where the invention mostly lies is in the hinge
mechanism (18) which is substantially different from hinges of the prior
art (not shown).
10020] When the panels (1fi) have run their course along the path of the guide
rails (12), they are moved away from the guide rails (12) to be put
against the door frat'ne (14), which results in the door panels (16)
applying pressure against an insulating stnp (20). This insulating strip
(20) can be derived fmm ex;sting types keown in the art or it can be
specially cxeated or adapted for this applicafion since, by moving
towards the insulating strip (20), the door (10) applies pressure onto the
strip (20) which can thus be thicker and nesilientiy deformable which can
provide for a better seal. A variety of elastomers could be used to
perform that function. It is not, however, within the scope of this
invention to give more details on the exact composition or properties of
such a sealing strip.
f0021J The hinge mechanism (18) is comprised of a clamshell module (22) and
a cam (24), For each two panels (16), there is a pair of such hinge
mechanism (18) that is shared since the clamsheil module (22) requires

CA 02574253 2008-07-24

to have a first part (22') on one panel (16) and a second part (22") on
another panel (161, this is obvious for anyone familiar with the workings
of any hinge.
i0o22] Each cam (24) is associated with a clamshell module (22) by way of a
plate (26) fixedly attached to a panel (16) proximal the clamshell module
(22). The cam (24) is rotationally attached to the plate (26) at its
proximal end (28) and rotationally attached to a blade (32) at its distal
end (30). Each blade (32) is connected to a caster (34) and each caster
(34) rolls within the guide rail (12) as is known for any prior art multiple
panel door except that in this case, the blades (32) act as if they were
door panels (16).
[00231 As the panels (10) move upwardly or downwardly, the cams (24) are in
a substantially parallel relation with the guide rails (12) as per fig.1 a.
When a first caster (34) reaches the end of the guide rail (12'), all
panels (16) are now parallel with the guide rails (12). A top cam (24')
has the unique feature of being, on ifs proximal end (28), rotationally
attached to a top plate (27) on a top panel (16") wherein another plate
(26) is also fixedly attached and, on its distal end (30), being rotationally
attached to a secondary cam (36)_
20[0024] This arrangement induces all cams (24) ta move from a substantially
parallel position in retation to the guide rails (12), to a substantially

CA 02574253 2008-07-24
$
perpendicular relation to the guide rails (12). As can be seen in fig. 9 a,
there is a a Y a corttiguration between the secondary cam (36), the cam
(24) and a top blade (38) whereas in ftg. 1 b there is is a T>)
configuration between these same elements.
5[0()25] The arctuate shape of the guide rails (12) forr.es this change in
configuration between what is seen in fig. 1 a and fsg. 1 b as a top panel
(16") passes from a horizontal position into a vertical position. The top
blade (38) being substantiaily longer than the cams (24) makes the top
panel (16") move faster which has the effer~ of changing that
eonfiguration and rift all other cams (24), which moves the door (10)
away from the frame (14) when the door (10) is opening, and moving the
door (10) against the frame (14) when it is dosing.
(0026) Also, a top cam (40) situated betrn+een a top caster (34') and a top
plate
(26') contributes to the changing in the confrguration by maintaining a
relative distance between the top plate (26') and the top caster (34) so
as to foroe the change between the conTiguration of fig. 1 a and the that
offig.7b.
f00271 As to a further discussion of the manner of usage and operation of the
present invention, the same should be apparent from the above
descAption. Accordingly, no further discussion relating to the manner of
usage and operation will be provided.

{00281 Wiih respect to the above description then, it is to be realized that
the
optinwm dinmnsional relationships for the parts of the invention, to
aiclude variations in size, materials, shape, form, function and manner of
operation, assembly and use, are deemed readily apparent and obvious
to one skiled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are
intended to be encompassed by the present invention.
10[(10291 Therefore, the foregoing is considered as illustrative only of the
principles of the invention. Further, since numerous modifications and
changes will readily occur to those skilled in the art, it is not desired to
limit the invention to the exad constnrction and operation shovrn and
described, and accordingly, all suitabie modifications and equivalents
may be resorted to, failing within the scope of the invention.
