PORTE COULISSANTE, DU TYPE COUPE-FEU OU ISOLANT

English Abstract

ABSTRACT OF THE DISCLOSURE
The invention provides a sliding door constructed for
use in fire protection or insulation comprising a framework
including a pair of side vertical profiles, each connected to a
top horizontal profile at a respective end by means of a flat,
right angled corner piece, an underguiding profile connected
near the bottom of said side vertical profiles, framework panels
interconnected to each other and attached to said profiles,
corner profiles clamping said panels against said top and vertical
profiles, a web rubber sealing profile extending over the edges
of said panels and clamped between said corner profiles and said
panels, and a respective wheel bracket with guiding wheels
attached at each top corner of said framework.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A sliding door constructed for use in fire protec-
tion or insulation comprising a framework including a pair of side
vertical profiles, each connected to a top horizontal profile at
a respective end by means of a flat, right angled corner piece,
an underguiding profile connected near the bottom of said side
vertical profiles, framework panels interconnected to each other
and attached to said profiles, corner profiles clamping said
panels against said top and vertical profiles, a web rubber
sealing profile extending over the edges of said panels and
clamped between said corner profiles and said panels, and a
respective wheel bracket with guiding wheels attached at each top
corner of said framework.
2. A sliding door of claim 1 in which a pair of
guiding wheels are attached to each wheel bracket with their
axes at an obtuse angle to each other.

Description

lo~zas
The invention relates to a sliding door particularly
for use in fire-proof, sound-proof or thermal insula-tion. Such
sliding doors must be mounted so as to be hermetically sealed
against a door-frame. For this purpose, the sliding door must
have a rigid construction, which usually is in the form of a
beam- and lath-construction put together in such a way that it
cannot shrink by means of glue or screws. The door is also pro-
vided with a front and a rear panel between which insulation
material may be heated, depending on the use of the sliding door.
Particularly with large sliding doors, this construction has the
disadvantage that the doors are difficult to handle and to trans-
port, among other reasons because of their weight. Especially
when long distance transportation is required, for example when
the doors are being exported, these disadvantages become unaccept-
able.
The present invention provides a sliding door, espe-
cially for use in fire-proof, sound-proof or thermal insulation,
which can be prefabricated as a construction kit in a workshop
and which can be easily assembled at the building-site.
Accordingly, the present invention provides a sliding
door constructed for use in fire protection or insulation compris-
ing a framework including a pair of side vertical profiles con-
nected to a top horizontal profile, an underguiding profile con-
nected near the bottom of said side vertical profiles, corner
pieces in the-shape of flat right angles connecting said top hori-
zontal profile at each of its ends to each of said side vertical
profiles, framework panels interconnected to each other and
attached to said profiles, corner profiles clamping said panels
against said profiles, a web rubber sealing profile ex-tending
over the edges of said panels and clamped between said corner
profile and said panels, and at least one wheel bracket with
guiding wheels attached at a top corner of said framework.

Such a construction has -the advantage that the entire
construction can be prefabricated in the right dimensions at the
factory, whereafter transportation as a construction kit is simple
and the assembly at the building-site can be carried out in a
simple manner, while a sliding door is obtained with sufficient
rigidity to yuarantee an hermetic sealing against the doorcase
of the sliding door.
The profiles are preferably metal profiles, which at
the top side of the door are connected to one another by corner
pieces, whereas at the under side the profiles are connected;to
one another by an under guiding profile.
The panels are clamped against the profiles by means of
corner profiles. A rubber sealing profile is clamped between the
panels and the corner profiles.
The invention will now be described in more detail, by
way of example only, in which the single figure shows an exploded
view of a sliding door assembly according to the invention.
In the drawing, the sliding door comprises a frame-work
formed of profiles 1, 2, 3 and a lower guiding profile, formed of
parts 4, 5 attached to the profiles 1 and 3 by means of screws.
The profiles 1 and 2 are connected to one another at the upper
edge of the door by means of a corner piece 6, and the profiles
2 and 3 are connected together by means of a corner piece 7.
Panels 8, 9, 10 are attached to the frame-work and
sealed against one another in a simple, known way. The panels
are clamped on the framework by means of corner profiles 11, 12
and 13 provided with a projecting lip. A sealing profile 14, con-
sisting e.g. of rubber, is clamped between the corner profiles
and the door panel.
A wheel bracket 15 having guiding wheels 16 and 17 is
attached to each corner of the upper edge of the framework.
